       DESCRIPTION OF THE INVENTION 
     Problems to be Solved 
       [0007]    The present invention is intended to provide an improved multilayer-structured discharge container. 
       Means to Solve Problems 
       [0008]    The first aspect of the present invention is intended to provide a multilayer-structured discharge container, where the structure is simple, the filling of a content and a pressurizing agent can be done easily, and the exhaust of the pressurizing agent after use can be done easily. 
         [0009]    The first aspect of discharge container of the present invention is characterized in that it comprises an outer container, an inner container accommodated in the outer container, and a valve assembly fixed by engaging with the outer periphery of the outer container, closing the outer container and the inner container, in which a content is accommodated in an accommodating chamber between the outer container and the inner container, and a pressurizing agent is filled in a pressurizing chamber in the inner container, in which the valve assembly is provided with a valve mechanism communicating/shutting off a discharge passage of the content which communicates the accommodating chamber and atmospheric air, a valve holder which accommodates the valve mechanism, and a cap which fixes the valve holder to the outer container so as to cover the valve holder and the outer container, and in which it is possible to make the pressurizing chamber and atmospheric air communicated by applying a switching operation to the valve assembly. 
         [0010]    In the first aspect of discharge container of the present invention, it is possible to exhaust the pressurizing agent after use when the whole amount of the content is discharged, by applying the switching operation to the valve assembly. 
         [0011]    In any of the discharge container of the first aspect of the present invention, it is preferable that the valve holder has a housing to accommodate the valve mechanism and an annular flange arranged above the outer container, and that the accommodating chamber and atmospheric air are communicated through the housing and the annular flange. In this case, the structure of the valve assembly can be simplified. 
         [0012]    In any of the discharge container of the first aspect of the present invention, it is preferable that by applying the switching operation to the valve assembly, it is possible to make the pressurizing chamber and atmospheric air communicated through the valve mechanism. In this case, since the pressurizing agent is exhausted through the valve mechanism, the amount of exhaust can be controlled, which is safe. 
         [0013]    In any of the discharge container of the first aspect of the present invention, it is preferable that the valve mechanism is provided with a stem having two independent intra-stem passages, that the valve holder has an intra-holder discharge passage which communicates the accommodating chamber and atmospheric air, and an intra-holder gas passage which communicates the pressurizing chamber and atmospheric air, that the one intra-stem passage communicates with the intra-holder discharge passage, the other intra-stem passage communicates with the intra-holder gas passage, the other intra-stem passage is closed to discharge the content, and that the switching operation is the operation to make the other intra-stem passage open and to make the valve mechanism open. In this case, the pressurizing agent can be exhausted from the other intra-stem passage. And, since the pressurizing agent can be exhausted by performing the pushing down operation of the stem after the switching operation of the valve assembly, this is safe for a user. 
         [0014]    In the discharge container of the first aspect of the present invention, where the switching operation is the operation to open the intra-stem passage, it is preferable that a push button is attached to the stem detachably, the push button having a stem engaging portion to engage with the stem, a discharge hole to discharge the content, and an intra-button passage to connect the stem engaging portion and the discharge hole, that the stem engaging portion communicates the one intra-stem passage with the discharge hole, and shuts off the other intra-stem passage from atmospheric air, and that the switching operation is the operation to detach the push button and to open the valve mechanism. In this case, it is possible to perform the switching operation by detaching the push button, which is simple. 
         [0015]    In any of the discharge container of the first aspect of the present invention, it is preferable that the cap is made so as to be movable vertically to the outer container, an inner seal material being provided between the valve holder and the inner container, an outer seal material of circular cross section being provided between the outer cylindrical surface of the outer container and the inner cylindrical surface of the inner container, the cap being fixed to the fixed position of the outer container, a seal structure being made to be formed by the outer seal material and the inner seal material respectively to discharge the content, and that the switching operation includes to release the seal structure of the inner seal material, while the cap is moved to the temporary position upper than the fixed position to make the seal structure of the outer seal material maintained. In this case, since the switching operation is the operation to move the cap upward, the operation is easy, it is possible to prevent the wrong operation by a user while in use. 
         [0016]    In the discharge container of the first aspect of the present invention, where the switching operation is the operation to move the cap upward, it is preferable that the valve holder and the cap are connected integrally. In this case, the valve holder does not close the outer container and the inner container during filling. 
         [0017]    In the discharge container of the first aspect of the present invention, where the switching operation is the operation to move the cap upward, it is preferable that when the cap is moved to the temporary position and the seal structure of the inner seal material is released, the pressurizing chamber and the discharge passage of the content are communicated, and that the switching operation is the operation to move the cap to the temporary position and to release the valve mechanism. In this case, since the pressurizing agent is exhausted through the valve mechanism, the amount of exhaust can be controlled, which is safe. 
         [0018]    In the discharge container of the first aspect of the present invention, where the switching operation is the operation to move the cap upward, it is preferable that the inner seal material is compressed vertically. In this case, the inner seal material is released together with the ascending of the cap. 
         [0019]    In the discharge container of the first aspect of the present invention, where the switching operation is the operation to move the cap upward, it is preferable that the inner seal material is compressed horizontally. In this case, even if the cap is moved upward, since the seal structure is not released unless the inner seal material is released from the compression from the valve holder or the inner container, the switching operation can be done safely. 
         [0020]    The second aspect of the present invention is intended to provide a multilayer-structured discharge container of high productivity, being easy to fill a concentrate and a pressurizing agent. 
         [0021]    The second aspect of the discharge container of the present invention is characterized in that it is provided with an outer container, an inner container accommodated in the outer container, and a valve assembly closing the outer container and the inner container, the valve assembly has a concentrate passage which communicates a concentrate accommodating portion between the outer container and the inner container, and the exterior, and a gas passage which communicates the interior of the inner container and the exterior, and is provided with a check valve for concentrate which shuts off the concentrate passage to a fluid going toward the concentrate accommodating portion from the exterior, and communicates the concentrate passage to the fluid going toward the exterior from the concentrate accommodating portion. 
         [0022]    In the second aspect of the discharge container of the present invention, when the pressuring agent is filled through the valve assembly, the concentrate passage can be shut off by the check valve, the pressurizing agent does not enter into the concentrate accommodating portion. Hence, the pressuring agent can be filled after filling the concentrate in the concentrate accommodating portion and sealing the discharge container by attaching the valve assembly, the filling process of the concentrate and the pressurizing agent can be simplified, thereby the filling accuracy of the pressurizing agent is high and the productivity is high. In addition, since the check valve for concentrate communicates the concentrate passage to the fluid going toward the exterior from the concentrate accommodating portion, the exhaust of the concentrate is not affected. 
         [0023]    In any of the second aspect of the discharge container of the present invention, it is preferable that a check valve for gas is provided, which shuts off the gas passage to the fluid going toward the exterior from the gas accommodating portion in the inner container, and communicates the gas passage to the fluid going toward the gas accommodating portion from the exterior. In this case, the counter flow of the pressurizing agent after the filling of the pressurizing agent through the valve assembly can be prevented. Moreover, the pressurizing agent never leaks to the exterior during discharge of the concentrate. 
         [0024]    In any of the second aspect of the discharge container of the present invention, it is preferable that the check valve for concentrate has the concentrate passage and an evacuation passage extending from the concentrate passage, and a moving valve which moves between the evacuation passage and the concentrate passage, where the moving valve shuts off the concentrate passage by moving toward the concentrate passage side to the fluid going toward the concentrate accommodating portion from the exterior, and communicates the concentrate passage by moving toward the evacuation passage side to the fluid going toward the exterior from the concentrate accommodating portion. In this case, the manufacture is easy and the productivity is high. 
         [0025]    The third aspect of the present invention is intended to provide a multilayer-structured discharge container which can discharge safely a pressuring agent filled independently to a concentrate. 
         [0026]    The third aspect of the discharge container of the present invention is characterized in that it is provided with an outer container, an inner container accommodated in the outer container, and a valve assembly detachable to the outer container closing the outer container and the inner container, in which a first seal material compressed radially and a second seal material compressed axially are provided between the outer container and the valve assembly. 
         [0027]    The third aspect of the discharge container of the present invention is a discharge container provided with a new double seal structure, where after discharging the concentrate from the valve assembly, when discarding the product, the pressurizing agent can be exhausted safely by releasing the seal of the other seal material, while maintaining the seal of the one seal material. 
         [0028]    For example, by loosening the valve assembly to the outer container, when the valve assembly moves vertically to the outer container, the seal of the second seal material can be released, while maintaining the seal of the first seal material. Moreover, by loosening the valve assembly to the outer container, when the valve assembly expands radially (horizontally), the seal of the first seal material can be released, while maintaining the seal of the second seal material. 
         [0029]    As described above, the other seal is released by maintaining the one seal, without spouting the pressurizing agent to the exterior, the pressurizing agent is made to be communicated with the valve mechanism to make it possible to exhaust the pressurizing agent. 
         [0030]    After that, by operating the stem of the valve assembly, the pressurizing agent can be exhausted to the exterior. Particularly, since the stem is designed so that its amount of the spout is controlled by the stem hole, it is safe. Moreover, even if the valve assembly is loosened in the state that the concentrate remains, since the one seal material is maintained, the concentrate is not spouted to the exterior. In this case, after loosening the valve assembly, by operating the stem, the mixture of the concentrate and the pressurizing agent can be exhausted from the stem safely. 
         [0031]    In any of the third aspect of the discharge container of the present invention, it is preferable that the first seal material seals between the outer container and the exterior, the second seal material seals between the space between the outer container and the inner container. In this case, by releasing the seal of the second seal material, while maintaining the seal of the first seal material, two spaces can be communicated with each other without substantially opening the multilayer-structured discharge container. 
         [0032]    In any of the third aspect of the discharge container of the present invention, it is preferable that the pressurizing agent is filled in the inner container, the concentrate is accommodated in the space between the outer container and the inner container. 
         [0033]    In any of the third aspect of the discharge container of the present invention, it is preferable that the concentrate is accommodated in the inner container and the pressurizing agent is filled in the space between the outer container and the inner container. 
         [0034]    In the case that the concentrate and the pressurizing agent are accommodated even in any of the space, after discharging the concentrate, the pressurizing agent can be exhausted safely. 
         [0035]    In any of the third aspect of the discharge container of the present invention, it is preferable that the first seal material is provided between the outer periphery surface of the outer container and the inner periphery surface of the valve assembly. In this case, even if the valve assembly is loosened and the valve assembly moves vertically to the outer container, the seal is maintained. 
         [0036]    Particularly, it is preferable that the valve assembly has a cylindrical cap covered on the outer container, that the first seal material is an O ring of circular cross section, and that the first seal material is provided between an outer cylindrical portion provided in the outer periphery of the outer container and an inner cylindrical portion provided in the inner periphery of the cap. In this case, the seal structure by the first seal material can be made strong. 
         [0037]    In any of the third aspect of the discharge container of the present invention, it is preferable that the second seal material is provided between the outer container and the valve assembly. In this case, the seal can be released only by moving the valve assembly upward to the outer container. 
         [0038]    Particularly, it is preferable that the valve assembly has the valve holder arranged in the upper end of the outer container, and that the second seal material is provided between the outer container and the valve holder. In this case, it can be made to be of a simple structure. 
         [0039]    Further, it is preferable that the second seal material is provided between the outer container and the valve assembly through the inner container. In this case, by the second seal material, it is possible to seal between the outer container and the valve assembly, and between the inner container and the valve assembly. 
         [0040]    In any of the third aspect of the discharge container of the present invention, it is preferable that a flange portion arranged in the upper end of the outer container is provided in the upper end of the inner container, that the valve assembly has the valve holder arranged in the upper surface of the flange portion so as to close the inner container, and a cylindrical cap covered so as to close the outer container, fixing the valve holder to the outer container, that the first seal material is provided between the outer periphery surface of the outer container, and the inner periphery surface of the cap, and that the second seal material is provided between the outer container and the valve holder through the flange portion of the inner container. In this case, by loosening the cap upward, the second seal material can be released, while maintaining the first seal material, making it possible to exhaust the pressurizing agent safely. 
         [0041]    In any of the third aspect of the discharge container of the present invention, it is preferable that an innermost container accommodated in the inner container and closed by the valve assembly is further provided, In this case, after use, it becomes a two-fluid discharge container capable of exhausting the pressurizing agent safely. 
         [0042]    In any of the third aspect of the discharge container of the present invention, it is preferable that the valve assembly is detached by moving vertically to the outer container. In this case, it is possible to release the seal of the second seal material, while maintaining the seal of the first seal material. Particularly, it is preferable that the valve assembly and the outer container is detachable by a screw. In this case, when the valve assembly is loosened to the outer container, since the valve assembly can be moved gradually vertically, it can be made to be of a simple structure. 
         [0043]    The fourth aspect of the present invention is intended to provide a discharge container of double-layered structure, in which the discard of a pressurizing agent is easy. The fourth aspect of the discharge container of the present invention is characterized in that it has an outer container, an inner container accommodated in the outer container, a valve assembly closing the outer container and the inner container, and a discharge member attached to the stem of the valve assembly, that it is a double-layered discharge container partitioned into a first space between the outer container and the inner container and a second space inside the inner container, in the one space, the concentrate is filled, and in the other space, the pressurizing agent is filled, and that the valve assembly is provided with two independent passages; the concentrate passage which communicates the one space with the exterior, and a pressurizing agent passage which communicates the other space with the exterior, where the discharge member has a closing portion to close the pressurizing agent passage when being attached to the stem. 
         [0044]    Particularly, it is preferable that the valve assembly is provided with two independent passages, each having a cylindrical stem opening in the upper end thereof, the closing portion closing the upper end opening of the one intra-stem passage composing the pressurizing agent passage. 
         [0045]    In the fourth aspect of the discharge container of the present invention, the filling of the concentrate and the pressurizing agent is easy. Moreover, since it has the closing portion to close the pressurizing agent passage, when the discharge member is attached to the stem, the pressurizing agent is not exhausted to the exterior when the concentrate is discharged. And, when the concentrate is depleted and the double-layered discharge container is discarded, the discharge member is detached, and the pressurizing agent is exhausted to the exterior through the pressurizing agent passage. 
         [0046]    In any of the fourth aspect of the discharge container of the present invention, it is preferable that the stem is that in which an inner cylindrical portion and an outer cylindrical portion are formed coaxially, that the inner cylindrical portion protrudes upper than the outer cylindrical portion, and the closing portion is that which closes the upper end opening of the inner cylindrical portion or the outer cylindrical portion. In this case, since the operation direction of the discharge member (downward direction), and the closing direction of the closing portion to close the upper end opening is the same, the pressurizing agent does not leak during the operation of the discharge member (during the concentrate discharge). Particularly, it is preferable that the stem is that in which the inner cylindrical portion and the outer cylindrical portion are formed coaxially, the inner cylindrical portion protrudes upper than the outer cylindrical portion, and that the closing portion is that which closes the upper end opening of the inner cylindrical portion or the outer cylindrical portion. In this case, since the upper end opening of the concentrate passage and the upper end opening of the pressurizing agent passage become different height, the closing portion closing the upper end opening of the pressurizing agent passage can be made to be a simple structure while securing the upper end opening of the concentrate passage. Hence when operating the discharge member (during concentrate discharge), the pressuring agent passage can be certainly sealed, while securing the concentrate passage. 
         [0047]    In any of the fourth aspect of the discharge container of the present invention, it is preferable that an insertion hole is provided in the discharge member, which closes the upper end opening of the other intra-stem passage composing the concentrate passage, and is capable of inserting the inner cylindrical portion of the stem. In this case, when discarding the double discharge container, the pressurizing agent can be exhausted by detaching the discharge member, and by inserting the stem into the insertion hole of the discharge member so as to release the valve assembly. 
         [0048]    In any of the fourth aspect of the discharge container of the present invention, it is preferable that it has a protection cap attached to the upper end of the valve assembly, and that the insertion hole is provided in the protection cap, which closes the upper end opening of the other intra-stem passage composing the concentrate passage, and is capable of inserting the inner cylindrical portion of the stem. In this case, when discarding the double discharge container, the pressurizing agent can be exhausted by detaching the discharge member, and by inserting the stem into the insertion hole of the protection cap so as to release the valve assembly. 
         [0049]    The fifth aspect of the present invention is intended to provide a discharge container in which the sealability of the valve mechanism is stable, and the content can be discharged stably. 
         [0050]    The fifth aspect of the discharge container of the present invention is characterized in that it has a container body and a valve assembly to close the container body, that the valve assembly has a valve unit arranged in the upper end of the container body and a cylindrical cap fixing the valve unit to the container body, that the valve unit is provided with a valve mechanism, a cylindrical valve holder in which a first flange portion arranged in the upper end of the container body is formed accommodating the valve mechanism, and a valve cover which covers the opening of the valve holder, fixing the valve mechanism to the valve holder, and in which a second flange portion arranged above the first flange portion is formed, that above the first flange portion of the valve holder, a communicating hole which communicates the inside and outside of the valve holder is formed, and that a passage which is communicated with the communicating hole, and communicated with the container body, is formed between the first flange portion of the valve holder and the second flange portion of the valve cover. In the fifth aspect of the discharge container of the present invention, the passage can be securely provided regardless of the attaching (tightening) state of the cap to the container body. In addition, when a plurality of the passages is radially provided, the position alignment of the passage between the flange portion and the container body becomes easy. 
         [0051]    Further, it is particularly preferable when the passage is the concentrate passage to let through the concentrate. Further, when the cap is fixed to the container body by screwing, the valve unit is rotated along with the rotation of the cap, even if the above described passage and the passage between the flange portion and the container body are deviated from an initial setting, it is possible to make communication without being affected by the amount of spout, which is preferable. 
         [0052]    In any of the fifth aspect of the discharge container of the present invention, it is preferable that the valve unit is integrated in the state that the valve holder and the valve cover accommodates the valve mechanism. In this case, the seal structure of the valve mechanism is stable regardless of the attached state of the cap, which makes the handling in a manufacturing process easy, allowing stable filling of the pressurizing agent and the content. Particularly, it is preferable when the pressurizing agent is filled from the upper end opening of the cap. 
         [0053]    In any of the fifth aspect of the discharge container of the present invention, it is preferable that a temporary support portion supporting the flange portion of the valve unit at the position lower than the valve unit to the cap in the fixed state is provided in the inner surface of the cap. 
         [0054]    In this case, when in manufacturing, by making the temporary support portion of the cap support the valve unit, the valve assembly can be handled as one body. Since the valve unit is made to be somewhat movable vertically to the cap, the fine adjustment of the seal between the flange of the valve unit and the upper end of the container body can be performed by the press-in quantity of the cap. Particularly, in the case that the cap and the container body are screwed, when the cap is rotated, since the cap can be idled to the valve unit, there never occurs such a problem that the seal materials sealing between the valve unit and the inner container and further between the valve unit and the inner container are twisted or teared, which is preferable because the stable sealability can be obtained. 
         [0055]    In any of the fifth aspect of the discharge container of the present invention, it is preferable that it is provided with the inner container having flexibility accommodated in the container body, of which the opening is closed by the valve assembly, and that the passage communicates the communicating hole and the space between the container body and the inner container. In this case, it is possible to form two independent spaces (between the container body and the inner space, inside the inner space). 
         [0056]    Particularly, when filling the concentrate between the container body and the inner container, the concentrate can be introduced in the valve holder through the passage and discharged to the exterior. 
         [0057]    Particularly, it is preferable that beneath the first flange portion of the valve holder, a second communicating hole which communicates the inside and the outside of the valve holder, and is communicated with the inside of the inner container is formed. In this case, by filling the first concentrate between the container body and the inner container, further, the second concentrate and the pressurizing agent in the inner container, it can be made to be the two-fluid discharge container. 
         [0058]    Further, it is preferable that it is provided with an innermost container having flexibility being closed by the valve assembly, and that the second communicating hole communicates the inside of the valve holder and the inside of the innermost container. 
         [0059]    In this case, three independent spaces (between the container body and the inner space, between the inner space and the innermost space, inside the innermost space) can be formed. In each space, two kinds of concentrate and the pressurizing agent which pressurizes simultaneously the two concentrates can be filled, making it possible to produce a two-fluid discharge product. 
         [0060]    The sixth aspect of the present invention is intended to provide a manufacturing method of a discharge product adopting a new filling method of the pressurizing agent. 
         [0061]    The sixth aspect of the manufacturing method of the discharge product is characterized in that it is a manufacturing method of the discharge product to fill a content and a pressurizing agent in a container having a container body and a valve assembly to close the container body, the valve assembly having a valve unit provided with a flange portion arranged in the upper end of the container body and a cylindrical cap fixing the valve unit to the container body, where the cap is held upper than a fixed position, from the upper end opening of the cap, the pressurizing agent is filled in the container body through between the cap and the valve unit, and between the flange portion and the upper end of the container body, then the cap is fixed to the fixed position. 
         [0062]    The sixth aspect of the manufacturing method of the discharge product is provided with a new filling method of the pressurizing agent being completely non-conventional. Particularly, since the filling of the pressurizing agent can be done from the upper end opening of the cap above the opening of the container body, a filling device can be made compact. 
         [0063]    In any of the sixth aspect of the manufacturing method of the present invention, it is a method to be preferable that the valve unit is provided with the valve mechanism, the valve holder having the cylindrical housing accommodating the valve mechanism, and the valve cover covering the opening of the housing, fixing the valve mechanism to the housing, in which the flange portion is formed, and that the valve holder and the valve cover are integrated in the state that the valve mechanism is accommodated. In this case, unitization makes the seal structure of the valve mechanism stable, being not affected by the attached state of the valve unit by the cap, allowing easy handling in the manufacturing process, thereby allowing stable production of the discharge product. 
         [0064]    In any of the sixth aspect of the manufacturing method of the present invention, it is a method to be preferable that the valve cover is provided in the opening of the housing, and is provided with a canopy portion in which a hole to let through the stem of the valve mechanism is formed, the cylindrical portion arranged in the outer periphery of the housing, and the flange portion protruding radially outward from the side surface of the cylindrical portion, that the upper end opening of the cap is arranged in the outer periphery of the cylindrical portion, and that the gap between the valve cover and the cap is opened facing upward. In this case, since the gap between the valve cover and the cap through which the pressurizing agent is filled is opened facing upward, when pressurizing agent is filled by attaching a pressuring agent filling device in the upper part of the discharge container, pressurizing agent can be filled without being made into a complicated structure. 
         [0065]    In any of the sixth aspect of the manufacturing method of the present invention, it is a method to be preferable that it is provided with a temporary support portion to support the valve unit lower than the position of the valve unit to the cap in the fixed state in the inner surface of the cap, and that the valve unit is made to be supported by the temporary support portion to fill the pressurizing agent. In this case, when filling the pressurizing agent, the valve unit moves beneath the cap by the pressure of the pressurizing agent, the gap between the valve unit and the cap can be secured certainly. Moreover, by the filling pressure of the pressurizing agent, it is possible to prevent the valve unit from closing the opening of the container body and plugging the filling passage of the pressurizing agent. Further, before filling the pressurizing agent, by making the temporary support portion of the cap support the valve unit, the valve assembly can be treated as one part, the process until the cap is supported upper than the fixed position can be simplified. 
         [0066]    In any of the sixth aspect of the manufacturing method of the present invention, it is a method to be preferable that the discharge container is accommodated in the container body, and is provided with the inner container having flexibility closed by the valve assembly, and that the pressurizing agent is filled in the inner container or in the space between the container body and the inner container. In this case, the filling of the pressurizing agent can be done easily. 
         [0067]    In any of the sixth aspect of the manufacturing method of the present invention, it is a method to be preferable that the discharge container is accommodated in the container body, and is provided with the innermost container having flexibility closed by the valve assembly, and that the pressurizing agent is filled in the space between the container body and the innermost container. In this case, the filling of the pressurizing agent can be done easily. 
         [0068]    The seventh aspect of the present invention is intended to provide a manufacturing method of a multilayer-structured discharge product which can control irregular contraction of the inner container. The seventh aspect of the manufacturing method of the discharge product of the present invention is characterized in that a multilayer structured discharge container comprises a bottomed outer container, an inner container having flexibility and having an approximately same shape as the inner surface of the outer container, accommodated in the outer container, and a lid body to close the mouth portion of the outer container and the mouth portion of the inner container, that a content composed of the concentrate and the pressurizing agent is filled in the multilayer structured discharge container, and that in the state that a guide member is inserted into the inner container positioned inside the outer container, after contracting the inner container, the concentrate and the pressurizing agent are respectively filled. 
         [0069]    In the seventh aspect of the manufacturing method of the discharge product of the present invention, since the inner container is contracted in the state that the guide member is inserted into the inner container, it can be made to be an intended shape by controlling the contracted shape of the inner container. Hence, the contracted shape of the inner container between products becomes approximately constant (in other words, the content, particularly the storage portion of the concentrate is constant), the variation of quality can be suppressed. Moreover, it becomes possible to restore easily the contracted shape of the inner container, and as the result, it becomes also possible to suppress the remaining of the concentrate. In addition, since the inner container is previously contracted/deformed before filling the concentrate, the convergence of the contraction/deformation to the vicinity of the passage communicating with the storage portion is suppressed, allowing to secure the passage to the storage portion. 
         [0070]    In any of the seventh aspect of the present invention, it is preferable that the lower end portion of the guide member is positioned in the vicinity of the bottom portion of the inner container. In this case, it is possible to suppress such deformation as the inner container being raised, or the bottom portion is rolled up. As the result, it becomes possible to secure the passage to the storage portion certainly, the inner container becomes easy to restore the original shape, and the remaining of the concentrate can be further reduced. 
         [0071]    In any of the seventh aspect of the present invention, it is a method to be preferable that the lower end of the guide member is spherical. In this case, it can be prevented that during the contraction of the inner container, the guide member tends to break (penetrate) the bottom portion of the inner container. 
         [0072]    In any of the seventh aspect of the present invention, it is a method to be preferable that the contraction of the inner container is performed by filling gas between the outer container and the inner container. In this case, by filling gas between the outer container and the inner container, the inner container is easily contracted/deformed. 
         [0073]    In any of the seventh aspect of the present invention, it is a method to be preferable that the contraction of the inner container is performed by reducing the pressure inside the inner container. In this case, the inner container can be easily contracted/deformed. 
         [0074]    In any of the seventh aspect of the present invention, it is a method to be preferable that when contracting the inner container, the inner container is heated. In this case, the inner container gets soft, allowing easy contraction. 
         [0075]    In any of the seventh aspect of the present invention, it is a method to be preferable that irregularity or gap is formed in the outer surface of the guide member. In this case, loosening (fold) generated when the inner container is contracted can be provided in an intended position, suppressing the variation of quality between the products, and the products can get good appearance. 
         [0076]    In any of the seventh aspect of the present invention, it is a method to be preferable that the guide member is provided with a gas passage communicating the inside of the inner container and the exterior. In this case, it is possible to reduce the pressure inside the inner container through the guide member, the inner container can be easily contracted and deformed. 
         [0077]    In any of the seventh aspect of the present invention, it is a method to be preferable that the guide member is provided in the lid body. In this case, the inner container can be contracted in the state that the lid body is attached to the outer container, allowing to simplify the manufacturing process. 
         [0078]    In any of the seventh aspect of the present invention, it is a method to be preferable that the guide member is formed to be extendable and contractable. In this case, the guide member can be gradually contracted while supporting the gradually contracting inner container from inside, thereby the inner container is easy to be contracted along the shape of the guide member. 
         [0079]    In any of the seventh aspect of the present invention, it is a method to be preferable that the guide member is pulled out from the inner container, after the inner container is contracted. 
         [0080]    In any of the seventh aspect of the present invention, it is a method to be preferable that the guide member is saclike, having elasticity, and is made to be expandable and contractable by being expanded or contracted balloon-like. In this case, the continuous support of the inner container becomes possible by the guide member. 
         [0081]    The eighth aspect of the present invention is intended to provide a discharge product of double layer structure which can discharge a composition for discharge to the last, in which the leak of the pressurizing agent is little. 
         [0082]    The eighth aspect of the discharge product of the present invention is characterized in that it is provided with an outer container, an inner container having flexibility, accommodated therein, a valve assembly which closes the outer container and the inner container, and communicates a composition accommodating chamber between the outer container and the inner container with atmospheric air, and a composition for discharge filled in the composition accommodating chamber, and a pressurizing agent filled in the pressurizing chamber inside the inner container, where the composition for discharge is a homogeneous solution composed of the concentrate and a foaming agent dispersed uniformly in the concentrate. In the eighth aspect of the discharge product of the present invention, even if the passage communicated with atmospheric air from the composition accommodating chamber is plugged or becomes small due to the expansion of the inner container by the discharge of the composition for discharge, the passage is expanded by the foaming agent dispersed uniformly in the concentrate, it is possible to discharge the composition for discharge to the last. Moreover, since the composition for discharge is positioned around the pressurizing agent, it is possible to prevent the pressurizing agent from leaking by permeating the outer container. Moreover, since the composition for discharge and the pressurizing agent are filled in the independent separate spaces, even if the outer container is placed in any direction, the composition for discharge can be discharged, allowing to prevent an improper use to spout pressurizing agent only. Further, since the composition for discharge is made to be the homogeneous solution in which the forming agent is dispersed in the concentrate, even if shaking action for dispersing the foaming agent before discharge is not done, it is possible to discharge foam only by opening the valve mechanism between the composition accommodating chamber and atmospheric air. 
         [0083]    In any of the eighth aspect of the present invention, it is preferable that the pressurizing agent is dissoluble compressed gas which dissolves in the composition for discharge, and that the inner container is made of resin having permeability to the pressurizing agent. In this case, the dissoluble compressed gas permeates the inner container, and the dissoluble compressed gas can be dissolved in the composition for discharge, the foamability of the composition for discharge improves. Particularly, when carbon dioxide is used as the compression gas, not only the foamability is enhanced, but also such an effect as blood circulation promotion can be obtained. 
         [0084]    In any of the eighth aspect of the present invention, it is preferable that the steam pressure (gauge pressure) of the composition for discharge at 25° C. is 0.01-0.3 MPa. In this case, since the composition for discharge has a specific steam pressure, even if the passage communicating with atmospheric air from the composition accommodating chamber is plugged or becomes small due to the expansion of the inner container by the discharge of the composition for discharge, the effect of enlarging the passage is further higher, allowing the smooth discharge of the composition for discharge to the last. 
         [0085]    The ninth aspect of the present invention is intended to provide a discharge product which is easy to manufacture, and can discharge the content with its amount of discharge to be constant from the start of use to the just before the end of use.

         [0087]    In the ninth aspect of the discharge container of the present invention, even if the valve mechanism is activated and the content is discharged, the pressure in the pressurizing chamber is maintained to be constant, the discharge amount per unit hour can be made constant from start to finish. Moreover, since the pressure adjusting mechanism is independently accommodated in the inner container, there is no contact with the content, allowing stable pressure adjusting function. Further, according to the content filled between the outer container and the inner container, the permeation of the pressurizing agent filled in the inner container can be made little, the leak of the pressurizing agent when not in use can be made little. 
         [0088]    In any of the ninth aspect of the discharge container of the present invention, it is preferable that the pressure adjusting mechanism is attached to the lower end of the valve assembly. In this case, the assembling of the discharge container is simple. 
         [0089]    In any of the ninth aspect of the discharge container of the present invention, it is preferable that the pressure adjusting mechanism is provided with a high pressure chamber having a gas supplying hole communicated with the inside of the inner container, a reference pressure chamber sealed with a predetermined pressure, a piston which compresses/expands the reference pressure chamber according to the pressing pressure of the reference pressure chamber and the inner container, and a valve which shuts off/communicates the gas supply hole interlocked with the piston, where when the reference chamber is compressed smaller than the predetermined capacity by the piston, the valve shuts off the supply of gas, and when the reference chamber is expanded larger than the predetermined capacity by the piston, the valve communicates the gas supply hole. In this case, it becomes a stable pressure adjusting mechanism not affected by a temperature variation. 
         [0090]    Particularly, it is preferable that a gas container in which the high pressure chamber and the valve are integrated is accommodated in the inner container. In this case, when assembling the discharge container, since there is no need to fill the pressurizing agent into the high pressure chamber, the assembling of the pressure adjusting mechanism is simple. Further, it is preferable that the pressure adjusting mechanism is formed below the valve assembly, a cylinder portion to accommodate the piston is provided, and a gas container is attached to the lower end of the cylinder portion. In this case, the structure is simple. 
         [0091]    In any of the ninth aspect of the discharge container of the present invention, it is preferable that the bottom portion of the gas container is placed in the bottom portion of the inner container. In this case, since the bottom portion of the gas container is supported by the inner container, when attaching the valve assembly, the gas container is easy to be connected to the lower end of the cylinder portion. 
         [0092]    As the manufacturing method of the discharge product in which the pressurizing agent is filled in the discharge container of the ninth aspect of the present invention, a method can be cited, in which the outer container and the inner container are prepared, the gas container is accommodated in the inner container, and by fixing the valve assembly to the outer container and the inner container, the pressure adjusting mechanism is actuated, then the pressurizing agent is filled into the inner container from the gas container. In this case, a special filling process of the pressurizing agent is not necessary, it is possible to assemble the discharge product by a user. Thereby it is possible to build a new refilling system of an aerosol container. 
         [0093]    In any of the ninth aspect of the discharge container of the present invention, it is preferable that the pressure adjusting mechanism is accommodated by being hanged from the opening of the inner container, and there is provided a container holder for holding the gas container, a slit to communicate the inside of the container holder and the inside of the inner container is formed in the container holder. In this case, the position of the gas container becomes stable, and since the bottom portion of the gas container is supported by the container holder, when attaching the valve assembly, the gas container is easy to be connected with the lower end of the cylinder portion. Moreover, the size of the outer container and the inner container can be selected freely. 
         [0094]    As the manufacturing method of the discharge product in which the pressurizing agent is filled in the discharge container of the ninth aspect of the present invention, a method can be cited, in which the outer container and the inner container are prepared, the gas container is accommodated in the inner container, and by fixing the valve assembly to the outer container and the inner container, the pressure adjusting mechanism is actuated, then the pressurizing agent is filled into the inner container from the gas container. In this case, a special filling process of the pressurizing agent is not necessary, it is possible to assemble the discharge product by a user. Thereby it is possible to build a new refilling system of an aerosol container. As the manufacturing method of the discharge product in which the pressurizing agent is filled in the discharge container of the ninth aspect of the present invention, a method can be cited, in which the outer container and the inner container are prepared, the container holder in which the gas container is held is accommodated in the inner container, and by fixing the valve assembly to the outer container and the inner container, the pressure adjusting mechanism is actuated, then the pressurizing agent is filled into the inner container from the gas container. In this case, a special filling process of the pressurizing agent is not necessary, it is possible to assemble the discharge product by a user. Thereby it is possible to build a new refilling system of an aerosol container. 
         [0095]    The tenth aspect of the present invention is characterized in that the discharge container comprises an outer container, an inner container accommodated in the outer container, and a valve assembly engagingly fixed to the outer periphery of the outer container closing the outer container and the inner container, the content is filled in the accommodating chamber between the outer container and the inner container, and a pressurizing agent is filled in a pressurizing chamber inside the inner container, in which the valve assembly is provided with a valve mechanism which communicates/shuts off the discharge passage of a content communicating the accommodating chamber and atmospheric air, a valve holder accommodating the valve mechanism, and a cap which fixes the valve holder to the outer container so as to cover the valve holder and the outer container, in which an inner seal material is provided between the valve holder and the inner container, an outer seal of circular cross section is provided between the outer cylindrical surface of the outer container and the inner cylindrical surface of the cap, the cap is fixed to the fixed position in the outer container, the content is discharged by making the outer seal material and the inner seal material form a seal mechanism respectively, and in which when the cap is arranged in the temporary position upper than the fixed position, the outer seal material is made to form the seal structure, the inner seal material is not made to form the seal structure.

Below the screw  11   a , a cylindrical outer seal holding portion  11   b  consisting of an outer cylindrical portion  11   b   1  and an annular protrusion  11   b   2  of the lower end thereof are formed. In this cylindrical outer seal holding portion  11   b , an annular outer seal material A 1  whose cross section is circular is held. The outer cylindrical portion  11   b   1  is a portion to compress the outer seal material A 1  horizontally, the annular protrusion  11   b   2  is a portion to prevent the outer seal material A 1  from dropping out from the outer cylindrical portion  11   b   1 . Further, below the outer cylindrical portion  11   b , an annular protrusion  11   c  is formed, which is for such as holding the outer container  11  when assembling the discharge container  10 , and for hanging the outer container  11  when filling. The outer periphery shape of the annular protrusion  11   c  may be not only circular but also be shaped as being provided with a plane partially, for the prevention of the rotation of the discharge container  10 , and further may be made to be rectangular. 
         [0145]    The inner container  12  has substantially an identical shape with the inner surface of the outer container  11 , and is a flexible bottomed cylindrical container provided with a cylindrical body portion, a taper like shoulder portion and a cylindrical neck portion (refer to  FIG. 5A ). The inner surface of neck portion of the inner container  12  is shaped to be an inner cylinder portion  12   a  compressing an inner seal A 2  horizontally. The portion upper than the neck portion of this inner container  12  does not deform, the portion lower than the body portion has flexibility and deforms. The shoulder portion is composed so that the flexibility gradually becomes higher toward the body portion from the neck portion. In this embodiment, it gradually becomes thin toward the lower portion from the upper portion of the shoulder portion. The inner container  12  is transparent or translucent, of which the inside is made to be visible. In the upper end of the inner container  12 , a flange portion  12   b  protruding outward is formed. The flange portion  12   b  is arranged in the upper end of the outer container  11 . In the inner container  12 , a plurality of longitudinal passage grooves  12   c  extending vertically, formed continuously in the upper outer surface of the shoulder portion is arranged annularly at an equal interval through the outer surface of the neck portion from the lower surface of the flange portion  12   b.    
         [0146]    In this embodiment, four longitudinal passage grooves  12   c  are provided. However, the number thereof is not particularly limited. Two to eight is preferable. Moreover, the longitudinal passage groove  12   c  may be sufficient as long as it is provided at least from the upper end of the inner container  12  to the non-deformable lower end of the neck portion. The longitudinal passage groove of the shoulder portion can be properly selected according to the flexibility (thickness) of the shoulder portion. This longitudinal passage groove  12   c  serves as a discharge passage of the content filled in the accommodating chamber S 1  between the outer container  11  and the inner container  12 . In addition, the longitudinal passage groove may be made to be provided in the upper surface of the neck portion, the inner surface of the neck portion and the shoulder portion of the outer container  11 . Further, it may be made to be provided both in the inner surface of the outer container  11  and the outer surface of the inner container  12 . 
         [0147]    Such outer container  11  and inner container  12  are made so that an outer preform for the outer container in which the screw  11   a  is formed in the neck portion, and an inner preform for the inner container in which the flange portion  12   b  and the longitudinal passage groove  12   c  are formed in the neck portion are molded individually by injection molding etc. that the inner preform for the inner container is inserted into the outer preform for the outer container to prepare a two-layer preform. Then this two-layer preform is molded simultaneously into a portion lower than the shoulder portion of the outer container  11  and the inner container  12  by biaxial stretch blow molding etc. Thereby, the outer shape of the inner container  12  becomes a shape to be contactable with the inner surface of the outer container  11 , in other words, a substantially identical shape with the inner surface of the outer container  11 . 
         [0148]    As the outer container  11 , it is preferable to use thermoplastic synthetic resin such as polyethylene terephthalate, nylon. And, as the inner container  12 , it is preferable to use thermoplastic synthetic resin such as polyethylene terephthalate, polyethylene, polypropylene. In addition, synthetic resin of the same quality of material may be used for the outer container  11  and the inner container  12 , and synthetic resin of the different quality of material may be used for those. In this case, as the inner container  12 , rubber or synthetic resin having elasticity may be used. 
         [0149]    In addition, if the accommodating chamber S 1  and the valve assembly  13  are communicated by a longitudinal passage formed between the outer container  11  and the inner container  12 , the outer shape of the inner container  12  may be made to be a different shape to the inner surface of the outer container  11 . 
         [0150]    The valve assembly  13  is, as shown in  FIG. 2A , provided with a valve mechanism  16  which lets through two fluids independently and shuts off/communicates those simultaneously, a valve holder  17  which closes the outer container  11  and the inner container  12 , and a cap  18  which fixes the valve mechanism  16  to the inside of the valve holder, and fixes the valve holder  17  to the outer container  11 . 
         [0151]    The valve mechanism  16  comprises a stem  21  in which two independent first intra-stem passage  21   a  and second intra-stem passage  21   b , and a first stem hole  21   a   1  and a second stem hole  21   b   1  respectively communicated with those passages are formed, an annular first stem rubber  22   a  closing the first stem hole  21   a   1 , an annular second stem rubber  22   b  closing the second stem hole  21   b   1 , an elastic body  23  energizing the stem  21  upward always, and a cylindrical support member  24  provided between the first stem rubber  22   a  and the second stem rubber  22   b  supporting those. 
         [0152]    The stem  21  is that in which an inner cylindrical portion  25   a  and an outer cylindrical portion  25   b  whose lower end are closed are coaxially superimposed, the inner cylindrical portion  25   a  protrudes upper and also lower than the outer cylindrical portion  25   b . And, an annular space between the inner cylindrical portion  25   a  and the outer cylindrical portion  25   b  composes the first intra-stem passage  21   a , a columnar space in the inner cylindrical portion  25   a  coaxial with the first intra-stem passage  21   a  composes the second intra-stem passage  21   b . The first stem hole  21   a   1  is a hole formed by penetrating the outer cylindrical portion  25   a  radially so as to communicate with the lower portion of the first intra-stem passage  21   a . The second stem hole  21   b  is formed by penetrating the inner cylindrical portion  25   a  radially so as to communicate with the lower portion of the second intra-stem passage  21   b  in the lower portion than the first intra-stem hole  21   a  (in the inner cylindrical portion  25   a  protruding lower than the outer cylindrical portion  25   b ). Each outer end of the first stem rubber  22   a  and the second stem rubber  22   b  is supported to the inside of the valve holder  17  by a support member  24 , the inner end plugs the first stem hole  21   a   1  and the second stem hole  21   b   1 . And, the downward movement of the stem  21  makes the first stem hole  21   a  and the second stem hole  21   b  released from the inner ends of the first stem rubber  22   a  and the second stem rubber  22   b.    
         [0153]    In the support member  24 , a slit  24   a  communicating the inside and the outside thereof is provided. 
         [0154]    The valve holder  17  is, as shown in  FIG. 2B , is that in which an intra-holder discharge passage R 1  communicating the accommodating chamber S 1  with atmospheric air and an intra-holder gas passage R 2  communicating the pressurizing chamber S 2  with atmospheric air are independently provided. In detail, it has a cylindrical housing  26 , an annular flange  27  extending outward from the central side of the housing  26 , and a cylindrical plug portion  28  provided coaxially outward to the housing  26  in the lower surface thereof. 
         [0155]    The housing  26  has a first communicating hole  26   a  communicating the inside and the outside of the housing in the side surface, and has a second communicating hole  26   b  communicating the inside and the outside of the housing in the lower end. Moreover, in the upper end of the housing  26 , a first rubber support portion  26   c  supporting the first stem rubber  22   a  of the valve mechanism  16  is formed, and a second stem rubber support portion  26   d  supporting the second stem rubber  22   b  of the valve mechanism  16  is formed between the first communicating hole  26   a  and the second communicating hole  26   b , being the inner side surface. 
         [0156]    Further, the upper periphery of the first communicating hole  26   a  of the housing  26  is expanded in diameter through a step portion  26   e . And, in the bottom portion of the housing  26 , a plurality of leaf springs  26   f  is provided so as to protrude upward. This leaf spring  26   f  composes an elastic body  23  of the valve mechanism  16  (refer to  FIG. 2A ). In this embodiment, four leaf springs are annularly arranged at an equal interval. A nonmetal valve assembly can be composed by molding the elastic body  23  integrally with the housing  26 . 
         [0157]    However, an independent spring may be arranged between the bottom portion of the housing  26  and the stem  21  of the valve mechanism  16 . And, in the center of the bottom portion of the housing  26 , a cylindrical portion  26   g  protruding downward, communicating with the second communicating hole  26   b  is formed. The inside of the housing  26  is divided into two spaces by the second stem rubber  22   b  of the valve mechanism  16 . Stated differently, the inside of the housing  26  is divided into an upper space (a part of the intra-holder passage) between the first stem rubber  22   a  and the second stem rubber  22   b , and a lower space (a part of the intra-holder gas passage) lower than the second stem rubber  22   b  (refer to  FIG. 2A ). 
         [0158]    The annular flange  27  protrudes outward from the housing  26  between the first communicating hole  26   a  and the second communicating hole  26   b . In the upper surface of the annular flange  27 , a plurality of lateral passage grooves  27   a  is radially provided at an equal interval. This lateral passage groove  27   a  is made to be the same number as the longitudinal passage groove  12   c  of the inner container  12 , and is provided so that the arrangement thereof is superimposed with the longitudinal passage groove  12   c  in a planar view. 
         [0159]    The plug portion  28  is a cylindrical portion inserted along the inner surface of the neck portion of the inner container  12 . In the lower side surface thereof, an annular inner seal holding portion  28   a  to hold the inner seal material A 2  is formed. The bottom  28   a   1  of this inner seal material  28   a  compresses the inner seal material A 2  horizontally. 
         [0160]    Since the valve holder  17  is composed as described above, the intra-holder discharge passage is communicated with the housing  26  through the annular flange  27 . In other words, it is communicated with the housing  26  so as to circumvent the annular flange  27  passing through inside the housing  26 . Further in detail, it is composed of the upper space inside the housing  26 , the first communicating hole  26   a , and the lateral passage groove  27   a  of the annular flange  27 . Meanwhile, the intra-holder gas passage is composed of the lower space inside the housing  26  and the second communicating hole  26   b  of the housing  26 . 
         [0161]    The cap  18  has, as shown in  FIG. 2C , a circular plate like cover portion  31  closing the opening of the housing  26  of the valve holder  17 , an upper cylindrical portion  32  arranged in the outer periphery of the housing  26  extending downward from the edge portion thereof, an annular ring portion  33  extending outward radially from the lower end thereof, and a lower cylindrical portion  34  extending downward from the outer end thereof. 
         [0162]    The cover  31  is that which prevents the first stem rubber  22   a  from jumping upward. In the center of the cover  31 , a center hole  31   a  which lets through the stem  21  is formed. 
         [0163]    The upper cylindrical portion  32  is a portion which holds the housing  26  of the valve holder  17 , and forms a discharge passage of the content across the housing  26 . In the inner surface of the upper cylindrical portion  32 , an engaging protrusion  32   a  engaging with the step portion  26   e  of the housing  26  is formed. By tucking the valve holder  17  between the cover  31  and the engaging protrusion  32   a , the valve mechanism  16  is fixed to the valve holder  17  (housing  26 ) and holds the valve holder  17  (refer to  FIG. 2A ). In other words, the cap  18  and the valve holder  17  can be integrated. In addition, the lower inner surface (the inner surface lower than the engaging protrusion  32   a ) of the cylindrical portion  32  forms an annular gap G 1  across the outer periphery of the housing  26  (refer to  FIG. 2A ). This gap G 1  is communicated with the first communicating hole  26   a  of the housing  26 , composing a discharge passage of the content. 
         [0164]    The ring  33  is a portion to cover the upper surface of the annular flange  27  of the valve holder  17  so as to prevent the valve holder  17  from dropping off from the outer container  11 . In addition, since in the annular flange  27 , the lateral passage groove  27   a  is formed, a plurality of passages extending radially is formed between the ring  33  and the annular flange  27 . This passage composes a discharge pass (intra-holder discharge passage) of the content, and is communicated with the gap G 1 . 
         [0165]    The lower cylindrical portion  34  is a portion which is connected to the outer container  11 , and composes a discharge passage of the content across the valve holder  17 . The upper inner surface of the lower cylindrical portion  34  is designed so that the gap G 2  is secured across the outer end of the annular flange  27  of the valve holder  17  (refer to  FIG. 2A ). In the middle inner surface of the lower cylindrical portion  34 , a screw  34   a  engaging with the screw  11   a  of the outer container  11  is formed. 
         [0166]    And, in a position of the outer seal holding portion  11   b  of the outer container  11 , being the lower inner surface of the lower cylindrical portion  34  beneath the screw  34   a , an inner cylindrical portion  34   b  somewhat expanded in diameter than the annular step portion  11   b   2  is formed. This annular cylindrical portion  34   b  is a portion compressing the outer seal material A 1  radially across the outer cylindrical portion  11   b   1  of the outer container  11  (refer to  FIG. 1 ). 
         [0167]    The push button  14  is, as shown in  FIG. 2D , provided with a cylindrical stem engaging portion  14   a  formed in the lower surface, a discharge hole  14   b  provided in the front surface, and an intra-button passage  14   c  which communicates the stem engaging portion  14   a  and the discharge hole  14   b.    
         [0168]    The stem engaging portion  14   a  consists of a diameter-expanded hole  36  into which the outer cylindrical portion  25   b  of the stem  21  is inserted, and a diameter-reduced hole  37  into which the inner cylindrical portion  25   a  of the stem  21  is inserted, being provided in the upper portion thereof. The intra-button passage  14   c  is communicated with the upper portion of the diameter-expanded hole  36 . And, the upper end of the diameter-reduced hole  37  is closed. The height of the diameter-reduced hole  37  is made to be smaller than the protruding amount in regard to the outer cylindrical portion  25   b  of the inner cylindrical portion  25   a  (refer to  FIG. 1 ). Hence, when the stem  21  is inserted into the stem engaging portion  14   a , the upper portion of the inner cylindrical portion  25   a  is arranged inside the diameter-reduced hole  37 , the lower portion of the inner cylindrical portion  25   a  and the upper portion of the outer cylindrical portion  25   b  are arranged inside the diameter-expanded portion  36 . Therefore, the upper end of the inner cylindrical portion  25   a  is closed by the upper end of the diameter-reduced portion  37 , and the upper portion of the outer cylindrical portion  25   b  is communicated with the intra-button passage  14   c , a space G 3  surrounded by the diameter-expanded portion  36  and the inner cylindrical portion  25   a  is formed (refer to  FIG. 1 ). 
         [0169]    Next, the discharge passage of the content connecting the accommodating chamber S 1  and atmospheric air excepting the push button  14 , and the gas passage (gas filling passage and gas exhaust passage) connecting the pressurizing chamber S 2  and atmospheric air are described referring to  FIG. 3 . The accommodating chamber S 1  is, as shown in  FIG. 3A , communicated with atmospheric air through the longitudinal passage groove  12   c , the gap G 2  between the lower cylindrical portion  34  and the valve holder  17 , the intra-holder passage (the lateral passage groove  27   a  between the ring portion  33  of the cap  18  and the annular flange portion  27  of the valve holder  17 , the gap G 1  between the lower inner surface of the upper cylindrical portion  32  of the cap  18  and the outer periphery surface of the housing  26  of the valve holder  17 , and the first communicating hole  26   a  of the housing  26 , and the upper space of the housing  26 ) and the first intra-stem passage  21   a  of the stem  21  of the valve mechanism  16 . Meanwhile, the pressurizing chamber S 2  is, as shown in  FIG. 3B , communicated with atmospheric air through the intra-holder gas passage (the second communicating hole  26   b  of the housing  26  and the lower space inside the housing  26 ) and the second intra-stem passage  21   b  of the stem  21  of the valve mechanism  16 . 
         [0170]    Next, the seal structure of the discharge container  10  is described referring to  FIG. 1 . In this discharge container  10 , the outer seal material A 1  is provided between the outer container  11  and the valve assembly  13 , the inner seal material A 2  is provided between the inner container  12  and the valve assembly  13 . In detail, the outer seal material A 1  is compressed horizontally and held between the outer cylindrical portion  11   b   1  of the outer container  11  and the inner cylindrical portion  34   b  of the cap  18  of the valve assembly  13 . And, the inner seal material A 2  is compressed horizontally between the inner cylindrical portion  12   a  of the inner container  12  and the bottom  33   a   1  of the inner seal holding portion  33   a  of the plug portion  33  of the valve assembly  13 . Stated differently, since the outer seal material A 1  and the inner seal material A 2  are compressed in a perpendicular direction to the axis of the outer container  11  and the inner container  12 , the seal is formed regardless of the degree of fitting of the cap  18  to the outer container  11 . Hence, even if the engaging of the cap  18  with the outer container  11  becomes loose due to an external force etc., the seal is never released, making the risk of spouting the content and the pressurizing agent little. In addition, as the outer seal material A 1  and the inner seal material A 2 , it is preferable to use a ring like gasket (O ring). The first aspect of the present invention is not limited to this seal structure. For example, as the discharge container  10   a  of  FIG. 4 , an annular plate seal material A 3  may be provided between the flange portion  12   b  of the inner container  12  and the annular flange  27  of the valve holder  17 . Or the inner seal material A 2  may be replaced with the plate seal material A 3 . And so forth, as long as the pressurizing chamber S 2  can be sealed, it is not limited to the seal structure of the inner seal material A 2 . Moreover, the outer seal material  17  is also provided beneath the screw  11   a , but it may be provided above the screw  11   a . And so forth, as long as the gap between the outer container  11  and the cap  18  can be sealed, the seal structure of the outer seal material A 1  is not limited. However, the seal structure of the discharge container  10  can reduce costs and is easy to assemble. 
         [0171]    Next, the use method of the discharge container  10  is described. As the use method, by pushing down the push button  14 , the content C can be discharged from the discharge hole  14   b  of the push button  14  (refer to  FIG. 3A ). In detail, by pushing down the stem  21  through the push button  14 , the first stem hole  21   a  and the second stem hole  21   b  of the stem  21  are opened, the discharge passage of the content opens. However, since the closing portion (upper end of a diameter-reduced portion  37 ) of the push button  14  blocks the upper end opening of the second intra-stem passage  21   b  of the stem  21 , only the passage of the content C of the valve assembly  13  is opened. In other words, the pressurizing agent P inside the inner container  12  (pressurizing chamber S 2 ) presses the inner container  12  so as to expand, the accommodating chamber S 1  is contracted, the content C is discharged from the discharge hole  14   b  from the accommodating chamber S 1  through the discharge passage of the content. After discharging whole amount of the content C, the push button  14  is detached, the stem  21  is pushed down (refer to  FIG. 3 b   ). Thereby, the gas discharge passage is opened and the pressurizing agent P is exhausted from the pressurizing chamber S 2 . This discharge container  10  may be discarded in this state. However, by detaching the cap  18  from the outer container  11 , each can be discarded separately. 
         [0172]    Next, the manufacturing method of the discharge product using the discharge container  10  is described. From a double preform, the outer container  11  and the inner container  12  are prepared. Then, the valve holder  17  and the cap  18  are integrated. The integrated valve assembly  13  is fixed to the outer container  11  to assemble the discharge container  10 . Then, in the state that the second intra-stem passage  21   b  of the stem  21  is closed, the stem  21  is pushed down to fill the content C in the accommodating chamber S 1 . After that, in the state that the first intra-stem passage  21   a  of the stem  21  is closed, the stem  21  is pushed down to fill the pressurizing agent P in the pressurizing chamber S 2 . In addition, before attaching the valve assembly  13  to the outer container  11 , the content C may be filled in the accommodating chamber S 1  from the opening of the longitudinal passage groove  12   c.    
         [0173]    As the content C, a content discharged in spray mist, a content discharged in foam, and a content discharged in creaminess or gel-like etc. can be cited. However, as the content C discharged in foam, it is preferable to use a uniform solution composed of a foaming agent dispersed uniformly in the content. In this case, since the foaming agent dispersed uniformly in the content expands the passage, it is possible to prevent the gap between the accommodating chamber S 1  and the longitudinal passage groove  12   c  from being blocked by the inner container  12  expanding to make the outer surface of the inner container  12  and the inner surface of the outer container  11  contact precedently. Thereby, the content is preferably discharged to the last. This uniform solution exerts a similar effect, even if it is not used in the first aspect of the present invention (the eighth aspect of the present invention), as long as it is that in which a discharge container is provided with an outer container, an inner container, and a valve assembly, where the pressurizing agent P is filled in the pressurizing chamber of the inner container, the content C is filled in the accommodating chamber S 1  between the outer container and the inner container. 
         [0174]    As such uniform solution, that which shows an external appearance of transparent or translucent is preferable. The content may be aqueous solution or oily solution. The gauge pressure of the content C at 25° C. is preferable to be 0.01-0.3 MPa, further, 0.02-0.2 MPa. When the gauge pressure is lower than 0.01 MPa, the effect of expanding the passage from the composition accommodating chamber S 1  to the longitudinal passage groove  17   b  becomes insufficient, there may be a case that the discharge is hard to be done. When the gauge pressure becomes higher than 0.3 MPa, the force becomes too strong causing the discharged foam is easy to be spattered. 
         [0175]    As an example of the content in which a foaming agent is dispersed uniformly in the content, for example, the following four types can be cited. 
         [0176]    [Content 1] 
         [0177]    A composition composed of a surface-active agent 1-30% by mass, a monovalent alcohol 5-30% by mass, an oil dissolving in ethanol 1-10% by mass, an aqueous content 40-90% by mass, and a foaming agent 10-60% by mass can be cited. The content (1) is, regardless of containing the foaming agent so much as 10-60% by mass in the composition, since the aqueous content has a specific composition, the foaming agent is dispersed uniformly in the aqueous content, does not separate, and shows transparent or translucent appearance. 
         [0178]    As the foaming agent, for example, propane, normal butane, isobutene, normal pentane, isopentane, and aliphatic hydrocarbon whose carbon number is 3-5 being a mixture of those (for example, LPG etc.), hydrofluoroolefin such as dimethyl ether, trans-1,3,3,3-tetrafluoroprop-1-ene and the mixture of those, of which the steam pressure (gauge pressure) is 0.1-0.5 MPa at 25° C. can be cited. As the surface-active agent, for example, a nonionic surface-active agent, an anionic surface-active agent, a cationic surface-active agent, an amphoteric surface-active agent, a high-molecular surface-active agent, and a silicone surface-active agent can be cited. 
         [0179]    As the monovalent alcohol, for example, monovalent alcohol of carbon number 2-5 such as ethanol, propanol, isopropanol, isobutyl alcohol, and amyl alcohol can be cited. 
         [0180]    As the oil dissolving in ethanol, for example, silicone oil such as octamethyltrisiloxane, decamethyltetrasiloxane, octamethylcyclotetrasiloxane, decamethylcyclopentasiloxane, dodecamethylcyclohexasiloxane, and methylphenylpolysiloxane, ester oil such as isopropyl myristate, myristyl myristate, decyl oleate, lauric acid isostearyl, myristic acid isocetyl, myristic acid isostearyl, octyldodecyl myristate, octyl palmitate, octyl stearate, oleic acid octyldodecyl, ethyl isostearate, isooctane acid cetyl, dioctanate ethylene glycol, dioleat ethylene glycol, propylene glycol dicaprylate, dioleate propylene glycol, glyceryl tricaprylate, glyceryl caprylate, glyceryl tricaprinate/tricaprylate, glyceryl triisostearate, try2-ethyl hexane trimethylol propane, octyldodecyl neopentanoate, dimethyl octanoic acid hexadecyl, cetyl lactate, triethyl citrate, dioctyl succinate, adipic acid diisopropyl, and diethoxyethyl succinate, liquid hydrocarbon oil such as liquid paraffin, and isoparaffin, higher fatty acid such as laulic acid, myristic acid, palmitic acid, stearic acid, oleic acid, and isostearic acid, higher alcohol such as lauryl alcohol, cetyl alcohol, stearyl alcohol, myristyl alcohol, oleyl alcohol, lanolin alcohol, and isostearyl alcohol can be used. Moreover, it is preferable to contain a polyhydric alcohol 1-15% by mass in the aqueous content for enhancing the dispersity of the aqueous content and the foaming agent. 
         [0181]    As the polyhydric alcohol, for example, divalent to trivalent polyhydric alcohol such as ethylene glycol, propylene glycol, 1-3 butylene glycol, and glycerin can be cited. 
         [0182]    Further, it is preferable to contain effective ingredients in the content according to the purpose and the use of the discharge products. As the effective ingredients, for example, a styling agent, a moisturizing agent, an ultraviolet absorber, an amino acid, a vitamin group, an antioxidant, a various extraction liquid, an antiseptic/microbicide, a deodorant, a deodorization agent, an antiphlogistic analgetic, a refrigerant, an astringent, an anti-inflammatory agent, a local anesthetic, an antihistamine, a whitening agent, and a perfume can be cited. 
         [0183]    [Content (2)] 
         [0184]    A composition composed of an aqueous content 90-99.5% by mass containing an nonionic surface-active agent 1-50% by mass, of which the HLB is 13-17, and an aliphatic hydrocarbon 0.5-10% by mass, of which the carbon number is 3-5 can be cited. Since the content (2) contains an aqueous content containing a predetermined quantity of nonionic surface-active agent having a predetermined HLB and a predetermined foaming agent at a predetermined ratio, the foaming agent disperses uniformly in the aqueous content, does not separate, and shows transparent to translucent appearance. Particularly, by containing a divalent to trivalent polyhydric alcohol 5-50% by mass in the aqueous content, it is easy to obtain a transparent and uniform composition.

         [0186]    In addition, other than the nonionic surface-active agent, an anionic surface-active agent, a cationic surface-active agent, an amphoteric surface-active agent, and a polymeric surface-active agent, a silicone surface-active agent such as a polyoxyethylene/methyl polysiloxane copolymer can be added. 
         [0187]    As the monovalent alcohol, the polyvalent alcohol, the foaming agent of the content (2), that which is similar with the content (1) can be used. Moreover, same as the content (1), it is preferable to contain effective ingredients. 
         [0188]    [Content (3)] 
         [0189]    A composition composed of an aqueous content 80-98% by mass containing an amino acidic surface-active agent 0.1-10% by mass and a monovalent alcohol of carbon number 2-3 25-60% by mass, and an aliphatic hydrocarbon (foaming agent) of carbon number 3-5 2-20% by mass can be cited. In the content (3), the foaming agent disperses in the aqueous content uniformly and does not separate, the content (3) showing transparent to translucent appearance. 
         [0190]    As the amino acidic surface-active agent, for example, N-acyl glutamic acid salt such as N-coconut oil fatty acid acyl-L-glutamic acid toriethanolamine, N-coconut oil fatty acid acyl-L-glutamic acid potassium, N-coconut oil fatty acid acyl-L-glutamic acid sodium, N-lauroyl-L-glutamic acid sodium, N-lauroyl-L-glutamic acid toriethanolamine, N-lauroyl-L-glutamic acid potassium, N-lauroyl-L-glutamic acid sodium, N-myristoyl-L-glutamic acid potassium N-myristoyl-L-glutamic acid sodium, and N-stearoyl-L-glutamic acid sodium, N-acyl glutamic acid such as N-coconut oil fatty acid acyl-L-glutamic acid, N-lauroyl-L-glutamic acid, and N-stearoyl-L-glutamic acid, N-acyl glycine salt such as N-coconut oil fatty acid glycine potassium and N-coconut oil fatty acid glycine sodium, N-acyl alanine salt such as N-coconut oil fatty acid-DL-alanine toriethanol amine can be cited. 
         [0191]    As the monovalent alcohol, the foaming agent of the content (3), that which is similar with the content (1) can be used. Moreover, it is preferable to contain effective ingredients. 
         [0192]    [Content (4)] 
         [0193]    A composition composed of an oily content 85-99% by mass containing a surface-active agent 1-20% by mass and an oily base 50-99% by mass, and a foaming agent 1-15% by mass in the content can be cited. 
         [0194]    As the surface-active agent, it is possible to use the nonionic surface-active agent similar with the content (1), particularly, it is preferable to use those in order to ease the foaming of the oily content; polyglycerol fatty acid ester such as monooleate diglyceryl, monostearate diglyceryl, monolaurate diglyceryl, monocaprylate diglyceryl, monolaurate hexadiglyceryl, monoomyristate hexaglyceryl, monolaurate pentaglyceryl, monomyristate pentaglyceryl, monooleate pentaglyceryl, monostearate pentaglyceryl hexastearate pentaglyceryl, trimyristate pentaglyceryl, trioleate pentaglyceryl, monolaurate decaglyceryl, monomyristate decaglyceryl, monostearate decaglyceryl, monoisostearate decaglyceryl, monooleate decaglyceryl, monolinoleic decaglyceryl, pentastearate decaglyceryl, and pentaoleate decaglyceryl. 
         [0195]    As the oily base, similar with the content (1), such as ester oil, avocado oil, camellia oil, turtle oil, macadamia nut oil, corn oil, mink oil, olive oil, rapeseed oil, sesame oil, castor oil, linseed oil, safflower oil, jojoba oil, wheat germ oil, coconut oil, palm oil, and rice salad oil can be cited. 
         [0196]    In addition, in the oily content, water 1-20% by mass, a monovalent alcohol 1-20% may be contained. Moreover, same as the content (1), it is preferable to contain effective ingredients. 
         [0197]    As the foaming agent that which same as the content (1) can be used, but it is preferable to use that in which the steam pressure (gauge pressure) at 25° C. is 0.5-0.85 MPa so as to ease the foaming of the oily content. 
         [0198]    As the pressurizing agent, a compressed gas such as carbon oxide, nitrogen monoxide, nitrogen, oxygen, air, and the mixture of those, liquefied gas such as liquefied petroleum gas, dimethyl ether and the mixture of those can be cited. 
         [0199]    In addition, when using a uniform solution composed of a content and a foaming agent, it is preferable to use nitrogen gas, compressed air, carbon dioxide, nitrogen monoxide etc. Particularly, when using soluble compressed gas of which the solubility to a content is high such as carbon dioxide, nitrogen monoxide, it acts as a foaming agent when the pressurizing agent is permeated from the pressurizing chamber S 2  to the composition accommodating chamber S 1 . Those are easy to foam even if the contained amount of the foaming agent is little, or the steam pressure of the foaming agent is low, which is preferable. In this case, for example, it is preferable that the pressure of the pressurizing agent is made to be 0.1-0.5 MPa. Stated differently, the steam pressure (gauge pressure) at 25° C. of the product pressure measured at the stem after filling the pressurizing agent is preferable to be 0.1-0.8 MPa so as to be 0.1-0.5 MPa higher than the steam pressure (gauge pressure) of the content before filling the pressurizing agent. 
         [0200]    When the steam pressure of the product pressure after filling the pressurizing agent is lower than 0.1 MPa, the effect of filling the pressurizing agent becomes difficult to obtain. When the steam pressure of the product pressure after filling the pressurizing agent is higher than 0.8 MPa, the momentum during discharge becomes too strong, causing the discharged foam easy to spatter. 
         [0201]    In the discharge container  10   a  of  FIG. 4 , the annular plate seal material A 3  compressed vertically is provided between the upper surface of the flange portion  12   b  of the inner container  12  and the lower surface of the annular flange  27  of the valve assembly  13 . Another composition is substantially same as the discharge container  10  of  FIG. 1 , and it has the outer container  11 , the inner container  12  and the valve assembly  13 . By providing the plate seal material A 3  as described above, the plate material is compressed vertically by the fastening of the cap, the sealability of the pressurizing chamber in the inner container is further enhanced. 
         [0202]    The manufacturing method of the discharge product using the discharge container  10   a  may be made to be same as that of the above described discharge container  10 . In  FIG. 5A-5H , another manufacturing method using the discharge container  10   a  is described. This manufacturing method is characterized in that before filling the content C and the pressurizing agent P, the inner container is contracted by inserting the guide member, after that the content C and the pressurizing agent P are filled (the seventh aspect of the present invention). Hence, it is sufficient to be a multilayer structured discharge container comprising the outer container and the inner container having approximately an identical shape with the inner surface of the outer container, having flexibility, being accommodated in the outer container, and a lid body (a valve assembly) closing the mouth portion of the outer container and the mouth portion of the inner container, even if being not used in the first aspect of the present invention, the similar effects can be obtained. The manufacturing method using the guide member can be adopted in any embodiment of the discharge container later described. 
         [0203]    Next, using  FIG. 5A-5H , it is described. First, same as the discharge container  10  of  FIG. 1 , a double preform consisting of the preform for the outer container  11  and the preform for the inner container  12  is prepared, by performing blowing (specifically biaxial stretch blowing) etc. the outer container  11  and the inner container  12  are simultaneously formed. 
         [0204]    Next, as shown in  FIG. 5B , the guide member  40  is inserted into the inner container  12 . The guide member  40  is, as shown in  FIG. 5  and  FIG. 6 , an approximately rod like hollow elastic body, the lower end of which is made to be contacted with the bottom portion  12   d  of the inner container  12 . Moreover, in the outer periphery surface, a convex portion (longitudinal rib)  40   a  and a concave portion (longitudinal groove)  40   b  are regularly formed alternately. Further, in the vicinity of the upper end portion is made to be smaller than the inner diameter of the mouth portion (the inner cylindrical portion  12   a  of the neck portion) of the inner container  12 , so that even in the state that the guide member  40  is inserted into the inner container  12 , the inside of the inner container  12  and atmospheric air are maintained to be communicated. 
         [0205]    Such guide member  40  is composed of an elastic material, for example, such as synthetic resin, silicone rubber. 
         [0206]    And, as shown in  FIG. 5C , a supply and exhaust device etc. (not shown in the figure) is connected to the opening of the guide member  40 , the guide member  40  is expanded to a degree not contacting the inner surface of the inner container  12 . 
         [0207]    Next, as shown in  FIG. 5D , a gas for contraction is filled in the accommodating chamber S 1  through the longitudinal passage groove  12   c  of the inner container  12 . When the gas is filled, the inner container  12  is contracted (contracted in the direction of reduced diameter), and contacts the outer surface of the guide member  40  expanded like a balloon. In addition, as the gas for contraction, that which is heated may be used. In this case, the inner container  12  is softened becoming easy to be contracted. The air in the inner container  12  is naturally exhausted to the exterior through the gap generated between the mouth portion (the inner cylinder portion  12   a  of the neck portion) and the guide member  40 . 
         [0208]    Moreover, as shown in  FIG. 5E , along with the contraction of the inner container  12  by the filling of the gas for contraction, air is evacuated from the guide member  40  to make it gradually contract (deflate). On this occasion, it is preferable that the inner surface of the inner container  12  is made to maintain the state to be contacted with the outer surface of the guide member  40  without a gap, the inner container  12  being supported from inside. By doing in this way, the irregular contraction of the inner container  12  is suppressed, making it easy to be contracted/deformed along the shape of the guide member  40 . 
         [0209]    After contracting the guide member  40  completely, as shown in  FIG. 5F , the guide member  40  is pulled out from the inner container  12 . In addition, on this occasion, the inner container  12  is in the state that a regular slack  12   h  is formed along the irregularity provided in the outer periphery of the guide member  40 , and this state is maintained. 
         [0210]    And, as shown in  FIG. 5G , the valve assembly  13  is screwed to the outer container  11 , the content C is filled in the accommodating chamber S 1 , the pressurizing agent P is filled in the inner container  12 . The filling of the content C into the accommodating chamber S 1  is carried out through the reversed root of the discharge passage of the content shown in  FIG. 3A , by pushing downward the stem  21 , in the state that the upper end of the second intra-stem passage  21   b  is closed. In this moment, since the inner container  12  is contracted, the passage to the accommodating chamber S 1  is secured, the content C can be smoothly filled. Moreover, the filling of the pressurizing agent P in the inner container  12  is carried out through the reverse root of the gas exhaust passage shown in  FIG. 3B , by pushing downward the stem  21 , in the state that the upper end of the first intra-stem passage  21   a  is closed. In addition, before attaching the valve assembly  13  ( FIG. 5F ), the content C may be filled in the accommodating chamber S 1  from the longitudinal passage groove  12   c.    
         [0211]    In addition, after filling the content C ( FIG. 5G ), the air in the inner container  12  before the filling of the pressurizing agent P can be exhausted through the discharge passage of the content by pushing downward the stem  21 , in the state that the upper end of the second intra-stem passage  21   b  is closed (refer to  FIG. 3B ). The air in the accommodating chamber S 1  can be exhausted by leaving the upper end of the second intra-stem passage  21   b  opened, before the pressurizing agent P is filled. 
         [0212]    After filling the content C and the pressurizing agent P ( FIG. 5H ), the stem  21  is pushed down, in the state that the upper end of the second intra-stem passage  21   b  is closed, to exhaust the air remaining in the accommodating chamber S 1 , the accommodating chamber S 1  is filled with the content C (to make it fluid-tight). Moreover, the removal of the content C and the pressurizing agent P remaining in the stem  21  is carried out to complete the manufacture of the discharge product. 
         [0213]    In the manufacturing method described above, since the inner container  12  is contracted in the state that the guide member  40  is inserted into the inner container  12 , the inner container  12  can be contracted along the guide member  40 , the inner container  12  can be deformed into an intended shape. Hence, the variation between the products can be suppressed, further, it becomes also possible to fill the content C in the accommodating chamber S 1  between the outer container  11  and the inner container  12  at an approximately uniform thickness. Moreover, since the irregularity is formed in the outer surface of the guide member  40 , the slack  12   h  by the contraction of the inner container  12  can be provided in an intended portion. Hence, for example, even if the outer container  11  has translucency, it makes a good appearance, further, by the slack  12   h  formed regularly, such an effect can be generated that the inner container  12  is easy to restore the original shape. 
         [0214]    Moreover, since the lower end of the guide member  40  contacts the bottom portion  12   d  of the inner container  12  before the contraction/deformation, such a deformation that the inner container  12  is raised, or the bottom portion  12   d  is rolled up can be suppressed, preventing the blocking of the longitudinal passage groove  12   c  by the shoulder portion of the inner container  12 , allowing uniform filling of the content C in the accommodating chamber S 1 . 
         [0215]    Further, when contracting/deforming the inner container  12  (to form the accommodating chamber S 1  between the outer container  11  and the inner container  12 ), since the gas whose viscosity is much lower compared with the content C is used, the fear that the contraction/deformation converges in the vicinity of the longitudinal passage groove  12   c  of the inner container  12  is small, allowing simple and uniform contraction of the inner container  12 . Moreover, since the method to contract the guide member  40  along with contraction of the inner container  12  is adopted, the inner container  12  becomes easy to be contracted along the guide member  40 , allowing more simple contraction of the inner container  12 . 
         [0216]    The manufacturing method of  FIG. 7  is characterized in that the guide member  42  is made to be a simple shape such as a columnar (rod-like) of which the cross section is, for example, circular, elliptic, polygonal. 
         [0217]    Even in this case, the shape of the inner container  12  after contraction becomes approximately constant, making it possible to suppress the irregular contraction of the inner container  12 . The manufacturing method is same as the method using the guide member  40  other than not having the process to inflate the guide member  40  and the process to deflate the guide member  40 . Therefore the process drawings are shown in  FIG. 7A - FIG. 7F , omitting specific description. In addition, in the present embodiment also, the lower end of the guide member  42  is formed to be spherical, preventing such a case that the guide member  42  resultantly break (resultantly penetrate) the bottom portion  12   d  during the contraction of the inner container  12 . 
         [0218]    The discharge container  10   b  of  FIG. 8A  is characterized in that a guide member  43  is attached to the lower end (the cylindrical portion  26   g ) of the valve holder  17 . Another composition is substantially same as the discharge container  10   a  of  FIG. 4 . The guide member  43  of the discharge container  10   b  is, different to the guide member  40  of  FIG. 5 , not pulled out from the inside of the inner container  12 , being left inside the inner container  12 . 
         [0219]    This guide member  43  is composed of hard resin, for example, such as polybutylene terephthalate, polyacetal, as shown in  FIG. 8B , and is of a hollow rod-like shape, the lower portion of which is formed to be spherical, and a convex portion  43   a  and a convex portion  43   b  are formed spirally, in the surface of which, a plurality of communicating holes  43   d  communicating the inside of the inner container  12  and a hollow portion  43   c  are formed so as to be along the concave portion  43   b . The hollow portion  43   c  can be communicated with atmospheric air through the gas passage of  FIG. 3B  in the state being attached to the cylinder portion  26   g  of the housing  26  of the valve assembly  13 . Hence, when the stem  21  is pushed downward, the inside of the inner container  12  and atmospheric air are communicated through the guide member  43 . 
         [0220]    In place of the guide  43 , a guide member  44  of  FIG. 8B  may be used. The guide member  44  is characterized in that it is of a tubular shape, inside and outside of which is flat, having a hollow portion  44   a , in the lower end thereof it has a spherical attachment  44   b  which makes the opening of the hollow portion  44   a  face laterally. 
         [0221]    The manufacturing method thereof is described. First, as shown in  FIG. 9A , for example, the outer container  11  and the inner container  12  are formed by molding a double preform using biaxial stretch blow molding etc. To the mouth portion of those containers, the valve assembly  13  to which the guide member  43  is attached is screwed. On this occasion, although the lower portion of the guide member  43  is not contacted to the bottom portion  12   d  of the inner container  12 , but is positioned near the bottom portion  12   d . Next, in the state that the stem  21  is pushed downward, a supply and exhaust device (not shown in the figure) such as a pump is connected to the second intra-stem passage  21   b , the air inside the inner container  12  is drained through a suction gas passage consisting of the communicating hole  43   d  of the guide member  43  and the hollow portion  43   c . Since the communicating hole  43   d  is formed so that the opening size becomes larger toward downward, in the lower side of the inner container  12  also, the pressure reduction is made to be carried out smoothly. In addition, on the occasion of the pressure reduction of the inner container, the upper end of the first intra-stem passage  21   a  is made to open, along with the contraction of the inner container  12 , air is made to be supplied between the outer container  11  and the inner container  12 . But, instead, it may be sufficient to fill a gas for contraction (heated gas may be sufficient). 
         [0222]    When the air in the inner container  12  is sufficiently drained, as shown in  FIG. 9B , the inner container  12  deforms along the outer shape of the guide member  43 . In other words, it becomes a shape in which concavity and convexity are spirally formed. 
         [0223]    And, as shown in  FIG. 9C , the manufacture of the discharge product  10   b  is completed by filling the content C in the accommodating chamber S 1 , filling the pressurizing agent P in the inner container  12 , and exhausting the air in the accommodating chamber S 1 . In addition, the filling method is same as the embodiment described above. But, the point that the pressurizing agent P is filled in the inner container  12  through the hollow portion  43   c  of the guide member  43  and the communicating hole  43   d  is peculiar to the present embodiment. 
         [0224]    In the manufacturing method of the discharge product using the discharge container  10   b , since the contraction of the inner container  12  is carried out in the state that the valve assembly  13  is attached, it has a merit that there is no need to pay attention to the return of air to the inner container  12 , allowing simple contraction work of the inner container  12 . Moreover, since the guide member  43  is not taken out, the work process is simplified to that extent. 
         [0225]    In the discharge container  10   c  of  FIG. 10 , a solid guide member  45  is attached to the lower end (the cylindrical portion  26   g ) of the valve holder  17 , the second communicating hole  26   b  of the housing  26  is formed in the lower side surface of the housing  26 . Another composition is substantially same as the discharge container  10   a  of  FIG. 4 . The guide member  45  of the discharge container  10   c  also is made to be left in the inner container  12  without being taken out from the inner container  12 . 
         [0226]    In such guide member  45  also, the deformation such as the inner container  12  being raised, and the deformation such as the bottom portion  12   d  being rolled up can be suppressed. Moreover, since the lower end is spherical, it is prevented that the guide member  45  resultantly breaks (penetrates) the bottom portion  12   d  of the inner container  12 . 
         [0227]    The discharge container  50  of  FIG. 11  is that in which a protection cap  53  to assist the exhaust of the pressurizing agent is provided. In detail, it comprises the outer container  11 , the inner container  12  accommodated in the outer container  12 , a valve assembly  51  closing the outer container  11  and the inner container  12 , and a push button (discharge member)  52  attached to the valve assembly  51 . Moreover, to the valve assembly  51 , the protection cap  53  to protect the stem  21  and the push button  52  of the valve assembly  51  are attached. Further, same as the discharge container  10   a  of  FIG. 4 , the annular plate seal material A 3  is provided. In addition, the outer container  11  and the inner container  12  are substantially same as those of the discharge container  10  of  FIG. 1 . 
         [0228]    A valve assembly  51  is, as shown in  FIG. 12A , provided with the valve mechanism  16  which independently shuts off/communicates two fluids, a cylindrical valve holder  56  accommodating the valve holder  16 , a valve cover  57  covering the valve holder  56  so as to fix the valve mechanism  16  to the inside of the valve holder  56 , and a cap  58  which fixes the valve mechanism  16 , the valve holder  56 , and the valve cover  57  to the outer container  11 . The valve mechanism  16  is substantially same as the discharge container  10  of  FIG. 1 . 
         [0229]    The valve holder  56  is different to the discharge container  10  of  FIG. 1  in the point that a plurality of elongated protrusions  27   b , not the lateral passage groove  27   a , protruding upward is formed in the upper surface of the annular flange  27  as shown in  FIG. 12B, 12C . 
         [0230]    Another composition is substantially same as the discharge container  10  of  FIG. 1 , and is provided with the cylindrical housing  26 , the annular flange  27 , and the plug portion  28  provided coaxially outward to the housing. Between these elongated protrusions  27   b  serves substantially as the lateral passage. 
         [0231]    The valve cover  57  is, as shown in  FIG. 12D , provided with a canopy portion  61  closing the opening of the housing  26  of the valve holder  57 , a cylindrical portion  62  extending downward from the edge portion thereof, arranged in the outer periphery of the housing  26 , and an annular hem portion  63  extending outward radially from the lower end thereof. The valve cover  57  is communicated with the first communicating hole  26   a  of the housing  26  between the hem portion  63  and the annular flange portion  27  of the valve holder  56 , and forms the lateral passage communicated with the accommodating chamber S 1  through the longitudinal passage groove  12   c  of the inner container  12 . 
         [0232]    In the center of the canopy portion  61 , a center hole  61   a  which let through the stem  21  of the valve mechanism  16  is formed. 
         [0233]    In the inner surface of the cylindrical portion  62 , an engaging protrusion  62   a  engaging with the step portion  26   e  of the housing  26  is formed. And, by tucking the valve holder  56  with the canopy portion  61  and the engaging protrusion  62   a , the valve mechanism  16  is fixed to the valve holder  56  (the housing  26 ) and holds the valve holder  56  (refer to  FIG. 12A ). In addition, the lower inner surface of the cylindrical portion  62  (inner surface lower than the engaging protrusion  62   a ) forms the annular gap G 1  with the outer periphery surface of the housing  26  (refer to  FIG. 12A ). This gap G 1  is communicated with elongated protrusion  27   b  of the above described valve holder  56  (intra-discharge passage). 
         [0234]    The hem portion  63  is provided with a first hem  63   a , a step portion  63   b  extending downward from the end portion of the first hem  63   a , and a second hem  63   c  extending outward radially from the lower end of the step portion  63   b . The first hem  63   a  is arranged thereon so as to cover the annular flange portion  27  (the elongated protrusion  27   b ) of the valve holder  57  (refer to  FIG. 12A ). The second hem  63   c  is arranged thereon so as to cover the third seal material A 3  (the flange portion  12   b  of the inner container  12 ) (refer to  FIG. 12A ). In addition, a plurality of downward grooves  63   d  formed continuously toward the lower surface of the second hem  63   c  is formed at an equal interval (refer to  FIG. 3A, 3D ). 
         [0235]    Being composed as described above, the lateral passage between the hem portion  63  of the valve cove  57  and the annular flange  27  of the valve holder  56  is composed by (the gap G 1 ) between the cylindrical portion  62  of the valve cover  57  and the housing  26  of the valve holder  56 , between the first hem  63   a  and the flange portion  27  (the lateral passage between the elongated protrusions  27   b ), and between the lower surface of the second hem  63   c  and the third seal material A 3  (the downward groove  63   d ). 
         [0236]    In addition, the space (lateral passage) between the gap G 1  and the elongated protrusion  27   b  may be communicated by extending the hem portion  63  of the valve cover  57  to the outer end of the third seal material A 3 . 
         [0237]    The cap  58  is, as shown in  FIG. 12E , provided with an upper cylindrical portion  66  covering the outer periphery surface of the cylindrical portion  62  of the valve cover  57 , an annular ring portion (pressing portion)  67  protruding radially outward from the lower end thereof, and a lower cylindrical portion  68  extending downward from the outer end thereof. The ring portion (pressing portion)  67  is arranged thereon so as to cover the hem portion  63  of the valve cover  57  (refer to  FIG. 12A ). The lower surface thereof is formed so as to contact the upper surface of the hem portion  63 . The upper end of the upper cylindrical portion  66  is substantially made to be same height as the upper end of the cylindrical portion  62  of the valve cover  57 . Hence, between the cap  58  and the valve cover  57  becomes an annular opening facing upward. 
         [0238]    In the inner surface of the lower cylindrical portion  68 , a screw  68   a  engaging with the screw  11   a  of the outer container  11  is formed. And, in the position of the annular protrusion  11   b   2  of the outer seal holding portion  11   b  of the outer container  11 , being beneath the screw  68   a , an inner cylindrical portion  68   b  somewhat diameter-expanded than the protrusion of the screw  68   a  is formed. This inner cylindrical portion  68   b  compresses the first seal material  16  radially across the outer cylindrical portion  11   b   1  of the outer container  11  (refer to  FIG. 11 ). Moreover, in the upper outer periphery of the lower cylindrical portion  68 , a protection cap engaging step portion  68   c  engaging with the protection cap  53  is formed. 
         [0239]    For the valve holder  56 , the valve cover  57 , and the cap  53 , it is preferable to use synthetic resin such as polyethylene terephthalate, nylon. 
         [0240]    Thereby, the nonmetal valve assembly  51  can be constructed. 
         [0241]    A push button  52  is, as shown in  FIG. 13A , substantially same as the push button  14  of the discharge container of  FIG. 1  other than that it is communicated with the intra-button passage  14   c  through a mechanical breakup mechanism  69  in the discharge hole  14   b . In detail, a columnar core  69   b  is inserted into a nozzle inserting hole  69   a  formed in the front surface of the push button  14  so as to be communicated with the intra-button passage  14   c , and a cup-like spray nozzle  69   c  in which the discharge hole  14   b  is formed in the center is attached to the front surface of the core  69   b . Hence, the content passing through the intra-button passage  14   c  passes through the outer periphery of the core  69   b , and passes through the groove of the rear surface of the spray nozzle  69   c , goes to the discharge hole  14   b  while being given a turning force. However, another spray mechanism may be provided according to use. 
         [0242]    As described above, the push button  14  is, by being attached to the stem  21  of the valve assembly  51 , closes the opening of the second intra-stem passage  21   b  of the stem  21 , the upper end surface  20  of the diameter-reduced hole  37  serves as a closing portion. 
         [0243]    The protection cap  53  is, as shown in  FIG. 13B , that which is cylindrical having a top surface  54 . In the center of the top surface  54 , the inner cylindrical portion  25   a  of the stem  21  can be inserted, and a stem inserting hole  54   a  for pressurizing agent exhaust locking the outer cylindrical portion  25   b  is formed. Hence, by turning inside out the protection cap  53  to insert the stem  21  into the stem inserting hole  54   a , and pushing down the stem  21 , the top surface  54  being the outer periphery edge of the stem inserting hole  54   a  engages with the upper end of the outer cylindrical portion  25   b , the stem  21  can be pushed down, while closing the first intra-stem passage  21   a.    
         [0244]    The double discharge container  50  composed as described above, same as the discharge container  10  of  FIG. 1 , can discharge the content C from the discharge hole  14   b  of the push button  52 , by pushing down the push button  52  (refer to  FIG. 14A ). 
         [0245]    Meanwhile, when the discharge container  10  is discarded, the push button  52  is detached, as shown in  FIG. 14B , the operation is carried out so that the inner cylindrical portion  25   a  of the stem  21  of the valve assembly  51  is inserted into the stem inserting hole  54   a  of the protection cap  53  of which the opening is placed facing downward. In this state, by pushing down the outer container  11 , the pressurizing agent P can be exhausted downward. In this moment, since the top surface  54  of the protection cap  53  closes the upper end opening of the first intra-stem passage  21   a  of the stem  21 , the pressurizing agent P in the inner container  12  (gas accommodating portion) only is exhausted from the stem  21 . Since the first intra-stem passage  21   a  is closed, even if the content remains, it is not scattered. And, the pressurizing agent P is exhausted in the protection cap  53 , preventing the scattering. 
         [0246]    Here, the gas passage (intra-holder passage) of the valve assembly  13  consists of the cylindrical portion  26   g , the second communicating hole  26   b , the lower space of the housing  26  of the valve holder  56 , and the second intra-stem passage  21   b  of the stem  21 . 
         [0247]    The discharge product using this discharge container  50  can be manufactured by any of the manufacturing method described above. 
         [0248]    The discharge container  50   a  of  FIG. 15A  is that in which an exhaust mechanism for pressurizing agent exhaust is provided in a push button  71 . Another composition is substantially same as the double discharge container  50  of  FIG. 11 .  FIG. 15A  shows the use state of the discharge container  50   a.    
         [0249]    In the push button  71  of the double discharge container  50   a , a stem hole  72  for pressurizing agent exhaust is formed. The stem hole  72  comprises a diameter-expanded hole  72   a  into which the outer cylindrical portion  25   b  of the stem  21  is inserted, a diameter-reduced hole  72   b  into which the inner cylindrical portion  25   a  of the stem  21  is inserted, being provided in the upper portion thereof, and a step portion  72   c  connecting the diameter-expanded hole  72   a  and the diameter-reduced hole  72   b . The upper end of the diameter-reduced hole  72   b  is opened. Another composition is same as the push button  52  of the discharge container  50  of  FIG. 11 . 
         [0250]    Being composed as described above, when discarding the discharge container  50   a , as show in  FIG. 15B , the push button  71  is detached from the stem  21 , the push button  71  is placed so that the opening of the diameter-reduced hole  72   b  faces upward, the outer container  11  is turned upside down, the outer cylindrical portion  25   b  of the stem is inserted into the diameter-reduced hole  72   b  to engage the upper surface of the push button  72  and the upper end of the outer cylindrical portion  25   b . In this state, by pushing down the outer container  11 , the stem  21  is pushed down, the pressurizing agent P can be exhausted into the stem inserting hole  72  (switching operation). Moreover, even if the content remains, since the upper opening of the outer cylindrical portion  25   b  is closed by the upper surface of the push button  52 , the content is never scattered. 
         [0251]    In addition, the use state is substantially same as the discharge container  10  of  FIG. 1 , by pushing down the push button  71  in which the stem  21  is inserted into the stem engaging hole  14   a , the content C is discharged from the discharge hole  14   b  (refer to  FIG. 6A ). 
         [0252]    The discharge container  50   b  of  FIG. 16  is also that in which the discharge mechanism for pressurizing agent exhaust is provided in a push button  74 . Another composition is substantially same as the discharge container  50  of  FIG. 11 .  FIG. 16A  shows the use state of the discharge container  50   b.    
         [0253]    To the push button  74  of the double discharge container  50   b , an exhaust member  75  to assist the exhaust of the pressurizing agent is connected. In detail, in the upper surface of the push button  74 , an exhaust member holding hole  74   b  to hold the exhaust member  75  is formed. Moreover, below the diameter-reduced hole  36  of the stem engaging hole  14   a , an exhaust member engaging hole  74   a  further expanded in diameter is formed. Another composition is substantially same as the push button  52  of the double discharge container  50  of  FIG. 11 , and it is provided with the discharge hole  14   b  and the intra-button passage  14   c.    
         [0254]    The exhaust member  75  is that which is of flat plate-like, a recessed portion  75   b  in which a center hole  75   a  is provided is formed. The center hole  75   a  has a dimension (shape) letting through the inner cylindrical portion  25   a , and a dimension (shape) not letting through the outer cylindrical portion  25   b , the recessed portion  75   b  has a dimension (shape) letting through the outer cylindrical portion  25   b . The recessed portion  75   b  of the exhaust member  75  protrudes in the view from the back, and the protruding portion (the rear side of the recessed portion  75   b ) is engaged with the exhaust member holding portion  74   b  of the push button  74 , and is held. 
         [0255]    Being composed as described above, when discarding the double discharge container  50   b , as shown in  FIG. 16B , the exhaust member  75  is detached from the push button  74 , the rear surface of the recessed portion  75   b  is inserted into the exhaust member engaging hole  74   a  of the stem engaging hole  14   a  so that the recessed portion  75   b  faces downward, the stem  21  is inserted into the push button  74  being in this state (switching operation). Thereby, the upper end of the inner cylindrical portion  25   a  is not inserted into the diameter-reduced hole  37  of the push button  74 , the second intra-stem passage  21   b  is not closed. Meanwhile, the recessed portion  75   b  of the exhaust member  75  closes the upper end opening of the outer cylindrical portion  25   b , the first intra-stem passage  21   a  is closed. Hence, by pushing down the push button  74  in this state, the pressurizing agent P can be exhausted from the discharge hole  14   b . In addition, the use state is substantially same as the discharge container  50  of  FIG. 11 , by pushing down the push button  74  in which the exhaust member  75  is attached to the exhaust member holding hole  74   b , the content is discharged from the discharge hole  14   b  through the first intra-stem passage  21   a.    
         [0256]    The discharge container  80  of  FIG. 17  is that in which a pressure adjusting mechanism  81  to adjust the inner pressure of the inner container  12  is provided. In detail, it is provided with the outer container  11 , the inner container  12  accommodated therein, the valve assembly  13  closing the outer container  11  and the inner container  12 , fixed by being engaged with the outer periphery of the outer container, and a pressure adjusting mechanism  81  accommodated in the inner container  12  to adjust the inner pressure of the inner container  12 . 
         [0257]    In this discharge container  80  also, the content C is filled in the accommodating chamber S 1  between the outer container  11  and the inner container  12 , and the pressurizing agent P is filled in the pressurizing chamber S 2  inside the inner container. And, it is used by attaching the push button  14  to the valve assembly  13 . And, by detaching the push button  14  from the valve assembly  13 , and pushing down (switching operation) the stem  21  of the valve mechanism  16 , the pressurizing chamber S 2  and the atmospheric air can be communicated. 
         [0258]    In the discharge container  80 , the outer container  11 , the inner container  12 , the push button  14  are substantially same as those of the discharge container  10  of  FIG. 1 . The valve assembly  13  is also same as the valve assembly  13  of the discharge container  10  of  FIG. 1 , other than the point that a cylindrical high pressure chamber  82  of the pressure adjusting mechanism  81  is provided in the lower end of the housing  26  of the valve holder  17  of the valve assembly  13 . 
         [0259]    The pressure adjusting mechanism  81  is, as shown in  FIG. 18A , provided with a cylindrical high pressure chamber body  82 , a cylindrical cylinder portion  83  closing the lower end thereof, a valve rod  84  which communicates/shuts off between the high pressure chamber body  82  and the cylinder portion  83 , a piston  85  interlocked with the valve rod  84 , being accommodated inside the cylinder portion  83 , a lower lid portion  86  closing the lower end of the cylinder portion  83 , and a spring  87  provided between the piston  85  and the lower lid portion  86 . 
         [0260]    In the pressure adjusting mechanism  81 , the inside of the high pressure body  82  serves as a high pressure chamber HP, between the piston  85  inside the cylinder portion  83  and the lower lid portion  86  serves as a reference pressure chamber SP, the valve rod  84  serves as a valve. And, the pressure inside the reference pressure chamber is adjusted by the inner pressure of the reference pressure chamber and the force of the spring  87  pressing the piston  85 . In addition, not providing the spring  87 , it is sufficient that the inner pressure of the reference chamber is made to be constant. 
         [0261]    The high pressure chamber body  82  is a cylindrical body provided coaxially with the housing  26  in the lower end of the housing  26  of the valve assembly  13 , and is communicated with the lower space of the housing  26  through the second communicating hole  26   b . In this discharge container  80 , the high pressure chamber body  82  is formed integrally in the lower end of the housing  26 . However, it may be made to be separate members and to be connected. 
         [0262]    The cylinder portion  83  is a cylindrical body having an upper bottom for closing the lower end of the high pressure chamber body  82 . In the side surface, a gas communicating hole  83   a  is formed. In the center of the upper bottom, a center hole (gas supply hole)  83   b  is formed, in the upper surface of the upper bottom, a cylindrical engaging portion  83   c  closing the high pressure chamber body  82 , being inserted inside the high pressure chamber body  82  tightly is provided. 
         [0263]    The valve rod  84  is a rod body inserted into the center hole  83   b  of the cylinder portion  83 , in the upper end of which a circular plate like clasping portion  84   a  is provided. A ring like valve seal  88  is provided between the lower surface of the clasping portion  84   a  and the upper bottom of the cylinder portion  83 . Stated differently, when the valve rod  84  descends, the clasping portion  84   a  of the valve rod  84  presses the upper bottom of the cylinder  83  through the valve seal  88 , thereby the center hole  83   b  is closed. Meanwhile, when the valve rod  84  ascends, the compression to the valve seal  88  by the clasping portion  84   a  is released, opening the center hole  83   b . The piston  85  is that which is plate-like, and moves vertically on the inner surface of the cylinder portion  83  contacting tightly. 
         [0264]    In the upper surface, a valve engaging portion  85   a  engaging with the lower end of the rod body of the valve rod  84  is formed. The lower surface receives the spring  87 . In the side surface, a ring like seal material  89  is provided. In other words, by the vertical movement of the piston  85  inside the cylinder portion  83 , the reference pressure chamber SP is compressed/expanded. The lower lid portion  86  is a member to close the lower end of the cylinder portion  83  tightly. In the upper surface, a cylindrical engaging portion  86   a  inserted inside the cylinder portion  83  tightly, closing the lower end opening of the cylinder portion  83  is formed. The upper surface of the lower lid portion  86  receives the spring  87 . 
         [0265]    The pressure adjusting mechanism  81  composed as described above operates depending on the difference of the pressing force to the piston  85  by the inner pressure of the reference pressure chamber and the spring, and the pressing force to the piston  85  by the pressure of the inner container  12  (the pressurizing chamber S 2 ). 
         [0266]    In detail, when the pressing force from the reference pressure chamber SP becomes larger than the pressing force from the inner container  12 , the piston  85  moves so as to expand the reference pressure chamber SP, in other words, the piston  85  ascends (refer to  FIG. 8B ). Hence, the valve rod  84  ascends, the pressurizing agent P in the high pressure chamber HP is supplied to the inside of the inner container  12  through the center hole  83   b  and the gas communicating hole  83   a . Meanwhile, when the pressing force from the inner container  12  becomes strong by the supply of the pressurizing agent P inside the inner container  12 , the piston  85  moves so as to contract the reference pressure chamber SP. In other words, the piston  85  descends. Thereby, the valve rod  84  descends, the valve seal  88  between the clasping portion  84   a  of the valve rod  84  and the upper bottom of the cylinder portion  83  is compressed, the center hole  83   b  is shut off (refer to  FIG. 18A ). 
         [0267]    Next, the manufacturing method of the discharge product using the discharge container  80  is shown in  FIG. 19 . 
         [0268]    First, a double bottle consisting of the outer container  11  and the inner container  12  is formed. In this moment, so as to make the accommodating chamber S 1  open securely when filling the content, for example, using the above described guide member (the seventh aspect of the present invention), the inner container  12  may be contracted once. Meanwhile, a lid material in which the valve assembly  13  and the pressure adjusting mechanism  81  are connected is prepared (refer to  FIG. 19A ). The connected portion is preferable to be integrated. 
         [0269]    This lid material is fixed to the double bottle. After that, the stem  21  is pushed down, the pressurizing agent P is filled from the second intra-stem passage  21   b  (refer to  FIG. 19B ). In this moment, it is preferable to fill while closing the first intra-stem passage  21   a . Stated differently, before the pressurizing agent P is filled, since the force of pressing the piston  85  of the pressurizing chamber SP is larger than that of the inner container  12 , the center hole  83   b  is opened, the pressurizing agent P is supplied to inside the inner container  12  through the center hole  83   b  and the gas communicating hole  83   a . When the pressurizing agent P is filled in the inner container  12 , the force of pressing the piston  85  of the inner container  12  becomes larger than that of the pressurizing chamber SP, the piston  85  descends together with the valve rod  84 , the center hole  83   b  is shut off. After that also, by filling the pressurizing agent P inside the high pressure chamber HP, the pressure in the high pressure chamber HP is made to be sufficiently higher than the reference pressure chamber SP even in the expanded state (the state after the content C is discharged), where the outer surface of the inner container  12  contacts the inner surface of the outer container  11 . 
         [0270]    In addition, the filling of the content to the accommodating chamber S 1  may be carried out before the lid material in which the valve assembly  13  and the pressure adjusting mechanism  81  are connected is fixed to the double bottle, moreover, it may be filled from the first intra-stem passage  21   a  of the stem  21  after being fixed to the double bottle. 
         [0271]    Next, the use method of the discharge product is shown. The use method is that the stem  21  is pushed down by the push button  14  to open the valve mechanism  16 , the content C can be discharged by the pressure inside the inner container  12  (refer to  FIG. 20A ). By the discharge of the content C, the inner container  12  expands, when the inner pressure of the inner container  12  decreases, the pressure adjusting mechanism  81  operates as described above, and the pressurizing agent P is replenished to the inner container  12  from the high pressure chamber HP. When the pressure inside the inner container  12  becomes high, the piston  85  descends downward to stop the supply of the pressurizing agent P. Since this supply process and the supply stop process is carried out every time when the content C is discharged, the content C can be discharged at the same momentum to the last. 
         [0272]    After discharging the content C, as shown in  FIG. 20B , by detaching the push button  14  and pushing down (switching operation) the stem  21 , the pressurizing agent P in the high pressure chamber can be exhausted to the exterior. Along with this, since the center hole  83   b  of the pressure adjusting mechanism  81  is opened, the pressurizing agent P in the inner container  12  can be also discharged from the second intra-stem passage  21   b  of the stem  21  through the gas communicating hole  83   a  and the center hole  83   b . Further, by detaching the cap  18  from the outer container  11 , it can be discarded according to the material sorted. 
         [0273]    The discharge container  100  of  FIG. 21  is the first aspect of the present invention, and is that in which an inner seal material is provided between the valve holder and the inner container, an outer seal material whose cross section is circular is provided between the outer cylindrical surface of the outer container and the inner cylindrical surface of the cap, and by moving the cap to a temporary position upper than the fixed position, the seal structure of the inner seal material is released while maintaining the seal structure of the outer seal material. 
         [0274]    In detail, the discharge container  100  comprises the outer container  11  made of resin, the inner container  12  made of resin accommodated therein, a valve assembly  101  closing the outer container  11  and the inner container  12 , fixed by being engaged with the outer periphery of the outer container. The outer container  11  and the inner container  12  are substantially same as the discharge container  10  of  FIG. 1 , the content C is filled in the accommodating chamber S 1  between the outer container  11  and the inner container  12 , and the pressurizing agent P is filled in the pressurizing chamber S 2  in the inner container. A push button  102  is attached to the valve assembly  101 . 
         [0275]    In this discharge container  100 , the cap  18  of the valve assembly  101  is moved to the temporary position upper than the fixed position, and by pushing down (switching operation) the stem  106  of the valve mechanism  103 , the pressurizing chamber S 2  and atmospheric air can be communicated (refer to  FIG. 23 ). 
         [0276]    The valve assembly  101  is, as shown in  FIG. 22A , provided with a valve mechanism  103  which shuts off/communicates one fluid, a valve holder  104  closing the outer container  11  and the inner container  12 , and the cap  18  which fixes the valve mechanism  103  to the inside of the valve holder  104 , and fixes the valve holder  104  to the outer container  11 . The cap  18  is substantially same as the cap  18  of the discharge container  10  of  FIG. 1 . 
         [0277]    The valve mechanism  103  comprises a stem  106  in which a stem hole  106   a  communicating the inside and the outside is formed in the lower portion, an annular stem rubber  107  closing the stem hole  106   a , and an elastic body  108  energizing the stem  106  always upward. 
         [0278]    The valve holder  104  has, as shown in  FIG. 22 , a cylindrical housing  109 , the annular flange  27  extending outward from the central side surface of the housing  109 , and the cylindrical plug portion  28  provided in the lower surface thereof, being outward coaxially with the housing  109 . 
         [0279]    The annular flange  27  and the plug portion  28  are substantially same as the annular flange  27  and the plug portion  28  of the discharge container  10  of  FIG. 1 . The inside of the housing  109  of the valve holder  104  is communicated with the accommodating chamber S 1  through the annular flange  27 . In detail, the inside of the housing  109  is communicated with the accommodating chamber S 1  so as to circumvent the annular flange  27  out of the housing  109 . 
         [0280]    The housing  109  is different to the housing  26  of the discharge container  10  of  FIG. 1  in the point that it does not have a second communicating hole and the second rubber support portion. Another composition is substantially same as the housing  26  of  FIG. 1 , in the side surface of the housing  109 , a communicating hole  109   a  is formed, a rubber supporting portion  109   b  supporting the stem rubber  107  is formed in the upper end of the housing  109 , and a plurality of leaf springs  109   c  composing an elastic body  108  is formed protruding upward in the bottom portion of the housing  64 . And, the upper periphery of the first communicating hole  109   a  of the housing  109  is expanded in diameter through a step portion  109   d.    
         [0281]    Being composed as described above, the discharge passage of the content connecting the accommodating chamber S 1  and atmospheric air excepting the push button  14  is, as shown in  FIG. 22 , communicated with atmospheric air through the longitudinal passage groove  12   c  of the inner container  12 , the gap G 2  between the lower cylindrical portion  34  of the cap  18  and the valve holder  104 , the content passage (the lateral passage groove  27   a  between the ring portion  33  of the cap  18  and the valve holder  104 , the gap G 1  between the lower inner surface of the upper cylindrical portion  32  of the cap  18  and the outer periphery surface of the housing  109  of the valve holder  104 , the first communicating hole  109   a  of the housing  109 , and the inside of the housing  109 ) and the stem  106  of the valve mechanism  103 . 
         [0282]    The push button  102  is, as shown in  FIG. 22C , that which is publicly known attached to a one-fluid type stem, and is provided with a stem engaging portion  102   a  formed in the lower portion, a discharge hole  102   b  formed in front, and an intra-button passage  102   c  connecting those. In addition, a mechanical breakup mechanism etc. as the push button  52  of  FIG. 11  may be adopted in the discharge hole  102   b  according to a discharge form. 
         [0283]    Next, the seal structure of the discharge container is described referencing to  FIG. 21 . 
         [0284]    In this discharge container  100  also, same as the discharge container  10  of  FIG. 1 , the outer seal A 1  is provided between the outer container  11  and the valve assembly  101 , and the inner seal material A 2  between the inner container  12  and the valve assembly  101  (refer to  FIG. 21 ). And, substantially same as the discharge container  10  of  FIG. 1 , since the outer seal material A 1  and the inner seal material A 2  are compressed to the axis of the inner and outer container vertically, the seal is formed regardless of the degree of fitting (degree of screwing) of the cap  18  to the outer container  11 . 
         [0285]    Further, in this discharge container  100 , the arrangement of the outer seal material A 1  and the inner seal material A 2  is made so that, when the cap  18  is ascended together with the valve assembly  101  in the state that the compression of the outer seal material A 1  by the lower portion of the inner cylindrical portion  34   b  of the cap  18  is maintained, the inner seal material A 2  ascends together with the valve assembly  101 , and departs from the inner cylindrical portion  12   a  of the inner container  12  (refer to  FIG. 23 ). Stated differently, when the cap  18  connected with the valve assembly  101  is ascended, the seal structure of the inner seal material A 2  can be released (temporary fixed position), while the seal structure of the outer seal material A 1  is maintained. In addition, in the discharge container  10  of  FIG. 1 , the arrangement may be made to be the same. Thereby, the under cup filling to fill the pressurizing agent at higher speed becomes possible. 
         [0286]    Next, the manufacturing method of the discharge container  100  is shown. The outer container  11  and the inner container  122  are prepared from a double preform. Then, the valve holder  104  and the cap  18  are integrated. Then, the seal structure of the outer seal material A 1  is formed, and the integrated valve assembly  101  is fixed temporarily so that the seal structure of the inner seal material A 2  is not formed (refer to  FIG. 23 ). In this state, the housing  109  of the valve holder  104  and the pressurizing chamber S 2  are communicated (refer to the thick line of  FIG. 23 ). In this state, the stem  106  is pushed down, and from the stem  106 , the pressurizing agent P is filled. After that, the cap  18  of the valve assembly  104  is fixed actually to the outer container  11  to form the seal structure of the inner seal material A 2 . In this state, the stem  106  is pushed down, and the pressurizing agent P invaded to the accommodating chamber S 1  is exhausted. After that the content C is filled in the accommodating chamber S 1 . In this case also, as described above, it is preferable to carry out it after contracting the inner container  12  using the guide member. 
         [0287]    Next, the use method of the discharge product  100  is shown. The use method is same as the discharge container  10  of  FIG. 1 , pushing down the push button  102  to open the valve mechanism  103 , the content C can be discharged from the discharge hole  102   b  of the push button  102 . After discharging the whole amount of the content C, the cap  18  of the valve assembly  101  is moved to the temporary fixed position, the seal structure of the inner seal material A 2  is released, while maintaining the seal structure of the outer seal material A 1  (the temporary fixing position of  FIG. 23 ). Thereby, since the pressurizing chamber S 2  and the housing  109  are communicated, by pushing down the stem  106  (or the push button  102 ), the pressurizing chamber S 2  and atmospheric air can be communicated, the pressurizing agent P can be discharged from the stem  106 . Finally, by detaching the cap  18  from the outer container  11 , each can be sorted and discarded. 
         [0288]    The discharge container  110  of  FIG. 24  is that in which a valve assembly  111  is provided with a valve cover  115 , and the pressurizing chamber S 2  and atmospheric air are communicated only by moving the cap  113  of the valve assembly  111  to the temporary fixed position. In detail, it comprises the outer container  11 , the inner container  12  accommodated therein, and the valve assembly  111  closing the outer container  11  and the inner container  12 , being fixed by engaging with the outer periphery of the outer container  11 . The outer container  11  and the inner container  12  are substantially same as the discharge container  10  of  FIG. 1 , the content C is filled in the accommodating chamber S 2  between the outer container  11  and the inner container  12 , the pressurizing agent P is filled in the pressurizing chamber S 2 . To this valve assembly  111  also, the push button  102  etc. of the discharge container  100  of  FIG. 21  is attached. 
         [0289]    In this discharge container  110  also, the pressurizing chamber S 2  and atmospheric air can be communicated by moving the cap  113  of the valve assembly  111  to the temporary position upper than the fixed position, and by pushing down (switching operation) the stem  106  of the valve mechanism  103  (refer to  FIG. 23 ). 
         [0290]    The valve assembly  111  has a valve unit  112  to which the valve mechanism  103  is fixed, closing the outer container  11  and the inner container  12 , and a cylindrical cap  113  fixing the valve unit  112  to the outer container  11 . The valve unit  112  of the valve assembly  111  is, as shown in  FIG. 25A , provided with the valve mechanism  103 , the cylindrical valve holder  104  in which the annular flange (the first flange portion of the sixth aspect of the present invention)  27  arranged in the upper end of the outer container  11  is formed, accommodating the valve mechanism  103 , and a valve cover  115  in which the hem portion (the second flange portion of the sixth aspect of the present invention)  118  arranged above the annular flange  27 , fixing the valve mechanism  103  to the valve holder  104  is provided. Between the annular flange  27  of the valve holder  104  and the hem portion  118  of the valve cover  115 , the passage (the lateral passage groove  27   a ) extending outward radially is formed. The valve mechanism  103  and the valve holder  104  are substantially same as the discharge container  100  of  FIG. 21 . In addition, the plate seal material A 3  compressed in the vertical direction (the axis of the outer container) is provided across the flange portion  12   d  through the annular flange portion  27  of the valve holder  104  and the flange portion  12   a  of the inner container  12  (refer to  FIG. 24 ). 
         [0291]    The valve cover  115  is, as shown in  FIG. 25B , provided with a canopy portion  116  closing the opening of the housing  109  of the valve holder  104 , a cylindrical portion  117  extending downward from the edge portion thereof, arranged in the outer periphery of the housing  109 , and an annular hem portion  118  extending outward radially from the lower end thereof. 
         [0292]    In the center of the canopy portion  116 , a center hole  116   a  letting through the stem  106  of the valve mechanism  103  is formed. 
         [0293]    In the inner surface of the cylindrical portion  117 , an engaging protrusion  117   a  to engage with the lower end of a step portion  109   d  of the housing  109  is formed. And, by the canopy portion  116  and the engaging protrusion  117   a , the valve mechanism  103  is fixed to the valve holder  104 , the valve unit  112  is integrated. In addition, the lower inner surface of the cylindrical portion  117  (inner surface lower than the engaging protrusion  117   a ) forms the annular gap G 1  with the outer periphery surface of the housing  109 , and is communicated with the lateral passage groove  27   a  (refer to  FIG. 25A ). The hem portion  118  is arranged so as to over the annular flange  27  of the valve holder  104  in the upper portion thereof. In other words, the hem portion  118  is arranged in the upper end of the outer container  11  through the annular flange  27 . And, the valve cover  115  closes the outer container  11 . 
         [0294]    Since the valve cover  115  as described above is provided, the passage between the hem portion  118  of the valve cover  115  and the annular flange  27  of the valve holder  104  is securely formed regardless of the attached state of the cap  113 . 
         [0295]    The cap  113  of the valve assembly  111  is, as shown in  FIG. 25C , provided with an upper cylindrical portion  121  covering the outer periphery surface of the cylindrical portion  117  of the valve cover  115 , an annular connecting portion (pressing portion)  122  protruding outward radially from the lower end thereof, and a lower cylindrical portion  123  extending downward from the outer end thereof. The connecting portion (pressing portion)  122  is arranged on the hem portion  118  of the valve cover  115 , and presses the whole of the valve unit  112 . 
         [0296]    The upper end of the upper cylindrical portion  121  is made to be the same height as the upper end of the cylindrical portion  117  of the valve cover  115  (refer to  FIG. 25A ). Hence, the gap between the cap  113  and the valve cover  15  opens facing upward. 
         [0297]    In the inner surface of the lower cylindrical portion  123 , a screw  123   a  engaging with the screw  11   a  of the outer container  11  is formed. And, in the position of the annular outer seal holding portion  11   b  of the outer container  11 , being beneath the screw  123   a , an inner cylindrical portion  123   b  of which the diameter is somewhat reduced than the thread of the screw  123   a  is formed. This inner cylindrical portion  123   b  compresses the outer seal material A 1  across the outer cylindrical portion  11   b   1  of the outer container  11 . 
         [0298]    Moreover, above the screw  123   a , a plurality of support protrusions (temporary support portion)  123   c  engaging with the lower surface of the hem portion  118  of the valve cover  115  is annularly formed. 
         [0299]    It is preferable that the arranged position of the longitudinal passage groove  12   c  of the inner container  12  comes between the adjoining support protrusions  123   b  in a planar view. This support protrusion  123   c  is formed in the position where a gap between the upper surface of the hem portion  118  of the valve cover  115  and the lower surface of the connecting portion  122  (pressing portion) is formed, when engaging with the lower surface of the hem portion  118  of the valve cover  115 . This support protrusion  123   c  does not contact with the lower surface of the hem portion  118  after the discharge container  110  is assembled (after the cap  113  is fixed to the outer container  11 ). By providing the support protrusion  123   c , before attaching the valve assembly  111  to the outer container  11 , the valve unit  112  can be held with the cap  113 , the valve assembly  111  (the valve unit  112  and the cap  113 ) can be handled as one body. 
         [0300]    Further, by providing the support protrusion  123   c , as later described, during filling the pressurizing agent (temporary fixing in the position upper than the fixed position), the valve unit  112  moving downward to the cap  113  by the filling pressure of the pressurizing agent can be supported, the later described pressurizing agent filling passage can be secured, and it can be prevented that the opening of the outer container  11  is closed by the fall down of the valve unit  112 . 
         [0301]    Being composed as described above, as shown by the thick line of  FIG. 25 , a concentrate passage Z 1  of the valve assembly  111  reaches to the stem  106  from the longitudinal passage  12   c  of the inner container  12  communicating with the accommodating chamber S 1 , through the gap G 2  of the outside of the support flange  27 , between the support flange (the first flange portion)  27  and the hem portion (the second flange)  118  (the lateral passage groove  27   a ), the gap G 1  between the housing  109  and the valve cover  115 , the first communicating hole  109   a , and the inside of the housing  109 . 
         [0302]    Stated differently, by pushing down the stem  106  of the valve mechanism  103 , the stem rubber  107  bends, the inside of the housing  109  is communicated with the exterior, the concentration passage Z 1  is opened. Hence, the concentration C pressurized by the pressurizing agent P in the inner container (the pressurizing chamber S 2 ) is discharged from the stem  106  passing through the concentration passage Z 1 . 
         [0303]    Next, the use method of the discharge container  110  is shown. The use method is that, same as the discharge container  10  of  FIG. 1 , by pushing down the push button  102  to open the valve mechanism  103 , the content C can be discharged from the discharge hole  102   b  of the push button. 
         [0304]    After discharging whole amount of the content C, same as the discharge container  100  of  FIG. 21 , the cap  113  of the valve assembly  111  is moved to the temporary fixed position, the seal structure of the inner seal material A 2  is released, while maintaining the seal structure of the outer seal material A 1 . Thereby, since the pressurizing chamber S 2  and atmospheric air are communicated, the pressurizing agent P can be exhausted from an annular opening between the valve cover  115  and the cap  113  (the reverse direction of the thick line of  FIG. 26A ). Similarly, in the end, by detaching the cap  113  from the outer container  1 , each can be sorted and discarded. 
         [0305]    Next, an example of the filling method of the content C and the pressurizing agent P into the discharge container  110  (the manufacturing method of the discharge container) is described. 
         [0306]    First, a two-layer preform of the outer container  11  and the inner container  12  is prepared, the outer container  11  and the inner container  12  are simultaneously molded from the two-layer preform by biaxial stretch blow molding etc. (refer to  FIG. 5A ). In addition, the outer container  11  and the inner container  12  may be molded separately, and the inner container  12  is inserted into the outer container  12  while squeezing the inner container  12 . 
         [0307]    Then, as shown in  FIG. 26A , the outer container  11  is placed on a rotating table  126   a . Meanwhile, a pressurizing agent filling machine  127  equipped with a pressurizing agent filling nozzle  127   a  is attached to the cap  113  of the valve assembly  111 , the valve assembly  111  is arranged above the outer container  11 . And, to the valve assembly  111  (pressurizing agent filling machine  127 ), the outer container  11  is rotated to fasten the cap  113 , and the valve assembly  111  is held in the temporary fixed position upper than the fixed position. In other words, the cap  113  of the valve assembly  111  is not completely screwed to the outer container  11  to make the inner seal material A 2  and the plate seal material A 3  not exerting seal effect. In this moment, the pressurizing agent filling machine  127  holds the cap  113 , and at the same time, is attached to the cap  113  so that a space PS between the cap  113  and the pressurizing agent filling machine  127  is sealed so that the pressuring agent P does not leak. 
         [0308]    In this temporary fixed state, the pressurizing agent P is supplied to the space PS from the pressurizing agent filling nozzle  127   a . Thereby, the pressurizing agent P is filled inside the inner container  12  passing through a pressurizing agent filling passage PP from between the valve cover  115  and the cap  113 . In detail, the pressurizing agent filling passage PP reaches from between the cylindrical portion  117  of the valve cover  115  and the upper cylindrical portion  121  of the cap  113  to between the hem portion  118  of the valve cover  115  and the connecting portion (pressing portion)  122  of the cap  113 , the gap G 2  outside of the annular flange  27  of the valve holder  104  between the mutual holding protrusion  123   c , and between the annular flange  27  of the valve holder  104  and the flange portion  12   b  of the inner container  12  (the inner seal material A 2 ). In this moment, the valve unit  112  descends somewhat to the cap  113  by the filling pressure of the pressurizing agent P, and is supported to the engaging protrusion  123   c  of the cap  113 . Hence, the gap between the upper surface of the hem portion  118  of the valve cover  115  and the lower surface of the connecting portion  122  of the cap  113  (pressing portion) can be secured largely. Moreover, even if the filling pressure of the pressurizing agent P is applied to the valve unit  112 , the opening of the outer container  11  is never closed by the valve holder  104  etc. 
         [0309]    And, during the pressurizing agent filling, since the outer seal material A 1  seals between the lower portion of the cap  113  and the outer container  11 , the pressurizing agent P does not leak to the exterior from the lower end of the cap  113 . 
         [0310]    In addition, the cap  113  is covered by the pressurizing agent filling machine  127 , whole of the cap  113  may be accommodated in the sealed space PS (for example, as the imaginary line, the lower end of the pressurizing agent filling machine  127  is sealed with the shoulder portion of the outer container  11 ). In this case, even in the state that the outer seal material A 1  is omitted, or the outer seal material A 1  does not seal between the lower portion of the cap  113  and the outer container  11 , the pressurizing agent P can be filled. 
         [0311]    After filling the pressurizing agent P, the outer container  11  is further rotated to fix the valve assembly  111  to the outer container  11 . Thereby, the inner seal material A 2  and the plate seal material A 3  are compressed to seal the inside of the inner container  12 . 
         [0312]    After filling the pressurizing agent P, when the supply of the pressurizing agent P from the pressurizing agent filling machine  127   a  is stopped, the pressure inside the inner container  12  and the space PS becomes substantially equilibrium. Hence, when the outer container  11  is rotated and the cap  113  is descended to the outer container  11 , the valve unit  112  and the outer container  11  (the inner container  12 ) are integrated by the plate seal material A 3 , the valve unit slides  112  against the cap  113 . Thereby, the position between the lateral passage groove  27   a  of the valve unit  112  and the lateral passage groove  12   c  between the outer container  11  and the inner container  12  is hard to be misaligned. Further, the displacement, torsion, cutoff of the inner seal material A 2  between the outer container  11  and the valve unit  112  can be prevented. 
         [0313]    In addition, without providing the inner seal material A 2 , the flange portion  12   a  may be made to be a substitute by compressing the flange portion  12   a  of the inner container  12 . Moreover, the plate seal material A 3  may be omitted. 
         [0314]    After that, the stem  106  is pushed down to exhaust a small amount of pressurizing agent P and air invaded into the accommodating chamber S 1  (the space between the outer container  11  and the inner container  12 ). Finally, the content C is filled inside the accommodating chamber S 1  from the stem  106  while contracting the inner container  12 , the production of the discharge product is completed. Here, the outer container  11  is rotated to screw with the valve assembly  111 , but the cap  113  may be rotated so as to fix the valve assembly  111 . However, since the valve assembly  111  is connected to the pressurizing agent filling machine  127 , it is preferable to rotate the outer container  11 , because the equipment does not become complicated. 
         [0315]    As another example of filling method of the pressurizing agent (manufacturing method of discharge product) to the discharge container  110 , when the valve assembly  111  is held in the temporary fixed position upper than the fixed position to the outer container  11 , as shown in  FIG. 26B , the outer seal material A 1  is positioned lower than the lower end of the cap  113  to make the seal between the cap  113  and the outer container  11  not formed, the pressurizing agent filling machine  127  and the shoulder of the outer container  11  are sealed with a seal material  127   c , the pressurizing agent P may be filled from the pressurizing agent filling nozzle  127   a  arranged near the lower end of the cap  113  through a pressurizing agent filling passage PP 2 . The pressurizing agent filling passage PP 2  reaches from between the outer container  11  and the cap  113  to between the annular flange  27  of the valve holder  104  and the flange portion  12   b  of the inner container  12  (the inner seal material A 2 ). 
         [0316]    In the case of this filling method, since the valve unit  112  (the valve cover  115 ) moves upward by the filling pressure of the pressurizing agent, the hem portion  118  contacts the inner surface of the connecting portion  122  of the cap  113 , the pressurizing agent filling passage can be formed between the outer container  11  and the valve unit  112 , the pressurizing agent can be filled safely. Hence, the engaging protrusion  123   c  of the cap  113  may be omitted. Moreover, even the cap  113  is rotated for fixing to the outer container  11 , since the valve unit  112  and the outer container  11  (the inner container  12 ) are integrated by the plate seal material A 3 , and the valve unit  112  slides with the cap  113  and does not rotate against the outer container  11 , the position of the lateral passage groove  27   a  of the valve unit  112  and the position of the longitudinal passage groove  12   c  between the outer container  11  and the inner container  12  is hard to become misalignment, and the displacement, torsion, cutoff of the inner seal A 2  between the outer container  11  and the valve unit  112  can be prevented. When adopting this filling method, the cap  113  is fixed, and rotating the outer container  11 , the cap  113  may be fixed to the outer container  11 . Moreover, the filling from the both sides; the filling from between the cylindrical portion  117  of the valve cover  115  and the upper cylindrical portion  121  of the cap  113  (filling from the upper part, the passage PP of  FIG. 26A ); the filling from the lower end of the cap  113  (filling from the lower part), may be carried out. 
         [0317]    Further, in the case that this filling method is adopted, the outer seal material A 1  and the inner seal material A 2  may be arranged so that the cap  113  does not have the temporary fixed position. In other words, it is sufficient that when the outer seal material A 1  and the inner seal material A 2  make the cap  113  descend to the outer container  11 , the seal structure is formed simultaneously. 
         [0318]    The discharge container  130  of  FIG. 27A  is that in which the valve assembly and the outer container are fitted with a clip, not by screw type. Moreover, it is the two-fluid discharge type discharge container in which a pouch is accommodated in the inner container, two concentrates are accommodated therein, and are discharged simultaneously. 
         [0319]    The discharge container  130  is provided with a bottomed outer container  131  and the inner container  12  accommodated in the outer container, an innermost container  132  accommodated in the inner container  12 , and a valve assembly  133  closing the inner container  12  and the innermost container  132 . The valve assembly  133  has a valve unit  135  closing the outer container  131  and the inner container  12  and the innermost container  132 , to which the valve mechanism  16  is fixed, and a cylindrical cap  136  which fixes the valve unit  135  to the outer container  131 . And, a first concentrate C 1  is accommodated in the space (the first accommodating chamber S 1 ) between the outer container  131  and the inner container  12  of the discharge container  130 , a second concentrate C 2  is accommodated in the innermost container  42  (the second accommodating chamber S 3 ), the pressurizing agent P is filled in the inner container  12  (pressurizing chamber S 2 ), the two-fluid discharge type discharge product is produced. The inner container  12  is substantially same as the inner container  12  of the discharge container  10  of  FIG. 1 . 
         [0320]    In the outer container  131 , as shown in  FIG. 27B , a first annular protrusion  131   a  is formed in the outer periphery of the neck portion. In the first annular protrusion  131   a , an upper surface  131   b  is made to be a taper like surface expanded in diameter facing downward, a lower surface  131   c  is made to be a horizontal surface (perpendicular to the axis of the outer container  131 ). In this embodiment, two first annular protrusions  131   a  are provided, but it may be also one and more than three. Another composition is substantially same as the outer container  11  of the discharge container  10  of  FIG. 1 , an annular protrusion  11   b   2  and an outer cylindrical portion  11   b   1  are formed in the neck portion. 
         [0321]    The innermost container  132  is, as shown in  FIG. 27A , provided with a pouch  132   a  whose lower end is closed, and a connecting member  132   b  fixed to the upper end opening thereof. The pouch  132   a  is that in which a plurality of sheets is welded or bonded together. As the sheet, synthetic resin sheet such as polyethylene, polyethylene terephthalate, nylon, eval, vapor deposition resin sheet in which silica, alumina are evaporated on the synthetic resin sheet, and that in which synthetic resin sheet etc. is laminated on a metal sheet such as aluminum foil are used. The connecting member  132   b  is that which is cylindrical, pasted on the opening of the pouch  132   a , and is connected to the later described valve assembly  133 . As the connecting member  132   b , that in which synthetic resin such as polyethylene is injection-molded is used. 
         [0322]    The valve unit  135  of the valve assembly  133  is, as shown in  FIG. 28 , provided with the two-fluid type valve mechanism  16 , the cylindrical valve holder  17  in which the annular flange (the first flange portion)  27  arranged in the upper end of the outer container  131  is formed, and the valve cover  115  in which the hem portion  118  (the second flange portion of the sixth aspect of the present invention) arranged above the annular flange (the first flange portion of the sixth aspect of the present invention)  27  fixing the valve mechanism  16  to the valve holder  17 , being provided in the upper portion thereof is provided. The valve mechanism  16  and the valve holder  17  are substantially same as those of the discharge container  10  of  FIG. 1 . The valve cover  115  is substantially same as those of the discharge container  110  of  FIG. 24 . 
         [0323]    The cap  136  is, as shown in  FIG. 28 , has one or a plurality of second annular protrusions  136   a  engaging with a first annular protrusion  131   a  of the container body  131  in the inner surface of the lower cylindrical portion  123 . A lower surface  136   b  of a second annular protrusion  136   a  is made to be a tapered surface expanded in diameter downward, an upper surface  136   c  is made to be a horizontal surface. Another composition is substantially same as the cap  113  of the discharge container  110  of  FIG. 24 , and it has the upper cylindrical portion  121 , the connecting portion (pressing portion)  122  and the lower cylindrical portion  123 . 
         [0324]    Being composed as described above, as shown in  FIG. 29A , the first passage Z 1  of the valve assembly  133  reaches from the longitudinal passage groove  12   c  of the inner container  12 , to the gap G 2  outside of the annular flange  27 , between the annular flange  27  and the hem portion  118  (the lateral passage groove  27   a ), the gap G 1  between the housing  26  and the valve cover  115 , the first communicating hole  26   a , the upper space of the housing  26  (between the first stem rubber  27   a  and the second stem rubber  27   b ), and the cylindrical hole of the first intra-stem passage  21   a  of the stem  21 . Meanwhile, the second concentrate passage Z 2  of the valve assembly  133  reaches to the second communicating hole  26   b , the lower space of the housing  26  (the space lower than the second stem rubber  27   b ), and the center hole of the second intra-stem passage  21   b  of the stem  21 . In other words, by pushing down the stem  21  of the valve mechanism  16 , the first content C 1  and the second content C 2  are discharged from the stem  21  to the exterior through the first concentrate passage Z 1  and the second concentrate passage Z 2 . 
         [0325]    Next, the filling method of concentrate and the pressurizing agent in the discharge container  130  (manufacturing method of discharge product) is described. First, the outer container  131  and the inner container  12  are molded same as the discharge container  10  of  FIG. 1 . 
         [0326]    Then, the innermost container  132  in which the second concentrate C 2  is filled is connected to the cylindrical portion  26   g  of the housing  26  of the valve assembly  133 . The cap  136  of the valve assembly  133  to which the innermost container  132  is connected is attached to the pressurizing agent filling machine  127  (refer to  FIG. 29B ) equipped with the pressurizing agent filling nozzle  127   a , the valve assembly  133  is arranged above the outer container  131 . 
         [0327]    After that, the valve assembly  133  is descended to the outer container  131 , as shown in  FIG. 29B , the taper like upper surface  131   b  of the first annular protrusion  131   a  of the outer container  131  and the taper like lower surface  136   b  of the second annular protrusion  136   a  are made to contact, the cap  136  is held upper than the fixed position to the outer container  131 . In this temporary fixed state, same as the discharge container  110  of  FIG. 24 , the pressurizing agent P is filled from between the valve cover  17  and the cap  113  (the pressurizing agent filling passage PP). In this moment, since the outer seal material A 1  seals between the lower portion of the cap  136  and the outer container  131 , the pressurizing agent P does not leak to the exterior from the lower end of the cap  136 . And, since the valve unit  135  is held by the support protrusion  123   c , even if the filling pressure of the pressurizing agent P is applied, the valve unit  135  never closes the opening of the outer container  131 , the pressurizing agent passage PP is secured. 
         [0328]    After filling the pressurizing agent P, the valve assembly  133  are further descended. In other words, the second annular protrusion  136   a  of the valve assembly  133  is made to override the first annular protrusion  131   a , the upper surface  136   c  of the second annular protrusion  136   a  and the lower surface  131   c  of the first annular protrusion  131   a  are made to engage, making it to be a fixed state (refer to  FIG. 27 ). 
         [0329]    After fixing the outer container  131  and the valve assembly  133 , the first accommodating chamber S 1  is deaired, the first concentrate C 1  is filled from the stem  21  through the first concentrate passage Z 1 . In addition, the empty innermost container  132  is connected to the valve assembly  133 , after filling the pressurizing agent P between (pressurizing chamber S 2 ) the inner container  12  and the innermost container  132  in first, it may be filled through the second concentrate passage Z 2  from the stem  21 . 
         [0330]    In addition, in this discharge container  130  also, as another filling method of the pressurizing agent, same as the discharge container  110  of  FIG. 24 , by composing so that the outer seal A 1  is not formed in the temporary fixed state as  FIG. 26B , the pressurizing agent P may be filled from the lower end of the cap  136  (the tenth aspect of the present invention). Moreover, a slit may be provided in the first annular protrusion  131   a  of the outer container  131  of the discharge container  130  and the second annular protrusion  136   a  of the cap  136  so as to make each other let through. In other words, it is sufficient that between the adjoining first annular protrusions  131   a , the second annular protrusion  136   a  can pass through. Forming the slit as described above, after discharging whole amount of the content (after use), by rotating the cap  136  to ascend the cap  136  up to the temporary fixed position, the pressuring chamber S 2  is communicated with atmospheric air, the pressurizing agent P can be discharged from the opening of the upper end of the cap  136  and the valve cover  115 . 
         [0331]    In the discharge container  130  also, the content and the pressurizing agent may be filled after the inner container becomes accustomed to be contracted uniformly by the insertion of the guide member into the inner container  12 . Further, as the discharge container  140  shown in  FIG. 30 , a connecting portion  141   b  of an innermost container  141  is extended to the vicinity of the bottom portion of a pouch  141   a , it may be made to be a guide member concurrently serving as a dip tube. Another composition is substantially same as the discharge container  130  of  FIG. 27 . 
         [0332]    The discharge product using the discharge container  140  is manufactured as described below. 
         [0333]    First, into the outer container  11  and the inner container  12  molded by blowing, the innermost container  141  attached to the valve assembly  133  (the pouch  141   a  and the connecting member  141   b ) is inserted ( FIG. 31A ). In this moment, the valve assembly  133  is made to be in a state of being suspended. In other words, the outer seal material A 1  the inner seal material A 2 , and the plate seal material A 3  are not exerted. 
         [0334]    Next, a gas for contraction is filled in the first accommodating chamber S 1  between the outer container  11  and the inner container  12  to contract the inner container  12 . In this moment, the pouch  141   a  and the connecting member (tube)  141   b  functions as a guide member, the inner container  12  contracts/deforms along the outer surface of the pouch  141   a  (refer to  FIG. 31B ). In addition, when contracting the inner container  12 , if air etc. is filled inside the pouch  141   a , since the shape of contract and the size of the inner container can be adjusted, it is also possible to contract the inner container  12 , while exhausting the air inside the pouch  141   a.    
         [0335]    And, the pressurizing agent P is filled in the inner container from the lower end of the cap  136  through the gap between the inner container  12  and the housing  26 , at the same time as the completion of filling, the valve assembly  133  is perfectly screwed to the outer container  11  and sealed (what is called undercup filling:  FIG. 31C ). 
         [0336]    After that, the first concentrate C 1  is filled in the first accommodating chamber S 1  through the first intra-stem passage  21   a  of the stem  21 . Further, the second concentrate C 2  is filled in the pouch  24  through the second intra-stem passage  21   b  and a hollow portion  141   c  of the connecting member  141   b  and a communicating hole  141   d  ( FIG. 30  and  FIG. 31D ). And, by attaching a spray member  145  to the stem  21 , the manufacture of the discharge product is completed. In addition, the spray member  145  is composed so that any of the first intra-stem passage  21   a  of the stem  21 , the second intra-stem passage  21   b  of the stem  21  is not closed, by pushing down the spray member  145 , both of the first concentrate C 1  in the first accommodating chamber S 1  and the second concentrate C 2  in the pouch  24  are made to be discharged from the spray member  145 . Moreover, it may be made so that each is discharged independently. 
         [0337]    In addition, here, the innermost container  142  of the pouch is cited, but it may be formed from a preform of more than triple (multiple preform). 
         [0338]    The discharge container  150  of  FIG. 32  is that which is provided with a pressure adjusting mechanism  151  adjusting the inner pressure of the inner container  12 . In detail, it is provided with the outer container  11 , the inner container  12  accommodated therein, a valve assembly  101   a  closing the outer container  11  and the inner container  12 , being fixed by engaging with the outer periphery of the outer container, and a pressure adjusting mechanism  151  adjusting the inner pressure of the inner container  12 . The outer container  11  and the inner container  12  are substantially same as those of the discharge container  100  of  FIG. 21 , the content C is filled in the accommodating chamber S 1  between the outer container  11  and the inner container  12 , the pressurizing agent P is filled in the pressurizing chamber S 2 . The valve assembly  101   a  is substantially same as the valve assembly  101  of  FIG. 21  other than that, as shown in  FIG. 33 , a cylindrical cylinder portion  152  is integrally formed in the lower end (the lower end of the plug portion  28 ) of the housing  109 , and it has the valve mechanism  103 , the valve holder  104 , and the cap  18 . In this discharge container  100 , by moving the cap  18  of the valve assembly  101   a  to the temporary position upper than the fixed position, and pushing down (switching operation) the stem  106  of the valve mechanism  103 , the pressurizing chamber S 2  and atmospheric air can be communicated (refer to  FIG. 37A ). 
         [0339]    The pressure adjusting mechanism  151  is, as shown in  FIG. 34A , provided with a cylinder portion  152  described above, a piston  153  accommodated inside the cylinder portion  152 , an aerosol container (gas container)  154  in which high pressure gas is filled, being inserted into the lower end of the cylinder portion  152 , and a container holder  155  hanged from the opening of the inner container. In addition, in the pressure adjusting mechanism  151 , a space inside the cylinder potion  152  surrounded by the lower surface of the housing  109  and the piston  153  serves as the reference pressure chamber SP, the inside of the aerosol container  154  serves as the high pressure chamber HP, and the valve of the aerosol container  154  serves as a valve. 
         [0340]    The cylinder portion  152  extends further downward from the lower end of the plug portion  33 . In the lower portion of the cylinder portion  152 , a slit  152   a  going upward from the lower end is formed. Moreover, in the lower end, a holding claw  152   b  which holds the piston  153  so that the piston  153  of the later described pressure adjusting mechanism  151  does not fall before the valve assembly  101   a  is attached to the outer container  11  is formed. Stated differently, the pressure adjusting mechanism  151  is fixed to the lower end of the valve assembly  101   a  through the cylinder portion  152 , and is hanged inside from the opening of the inner container  12 . The piston  153  moves up and down contacting tightly the inner surface of the cylinder portion  152 . In other words, the piston  153  seals the pressurizing chamber S 2  and at the same time, seals the reference pressure chamber SP. 
         [0341]    And, by the up and down motion of the piston  153 , the reference pressure chamber SP is compressed/expanded. In addition, by the inside of the reference pressure chamber SP being compressed, the air inside is compressed, and the piston  153  receives a reaction force. 
         [0342]    The aerosol container  154  comprises a pressure resistant container  154   a , an aerosol valve  154   b  closing the opening thereof, and a push button  154   c  attached to a stem  154   b   1  of the aerosol valve  154   b.    
         [0343]    By pushing down the push button  154   c  to descend the stem  154   b   1 , the aerosol valve  154   b  is opened, the pressurizing agent P in the pressure resistant container  154   a  is sprayed from a discharge port  154   c   1  of the push button  154   c . The aerosol container  154  may be fixed to the cylinder portion  152  by engaging the holding claw  152   b  of the cylinder portion  152  with an annular recessed portion  154   d  formed in the outer periphery of the aerosol valve  154   b . In this moment, the piston  153  is arranged on the push button  154   c  of the aerosol container  154 . In addition, the push button  154   c  is not necessary to be provided as long as it is composed so that the stem  154   b   1  and the piston  153  are made to be interlocked. 
         [0344]    The container holder  155  makes it easy to engage the valve assembly  101   a  with the cylinder portion  152  by stabilizing the position of the aerosol container  154 , when the valve assembly  101   a  is attached to the outer container  11 . After attaching the valve assembly  101   a  also, it holds the aerosol container  154  to make it easy for the piston  153  and the push button to operate. In detail, it comprises a cylindrical holder body  155   a , a flange  155   b  formed on the upper end thereof, and a bottom portion  155   c  closing the lower end thereof. The inner upper surface of the holder boy  155   a  is made to be a cylinder, and is a portion to compress the inner container  12  radially. In the lower portion of the holder body  155   a , a slit  155   d  communicating between the holder body  155   a  and the inner container  12  is formed. And, in the lower inner surface of the holder body  155   a , a positioning rib  155   e  for positioning the aerosol container  154  is formed aligned radially. The container holder  155  is held by being clamped between the upper end (the flange portion of the inner container  12 ) of the outer container  11  and the annular flange  27  of the valve holder  17  of the valve assembly  101   a . Moreover, the lower surface of the flange portion  155   b  is a portion to compress the annular plate seal material A 3  downward. 
         [0345]    The pressure adjusting mechanism  151  composed as described above operates according to the difference of the pressure of the reference pressure chamber SP and the pressure of the inner container  12  (pressurizing chamber S 2 ). In detail, as shown in  FIG. 34B , when the pressure of the reference pressure chamber SP becomes larger than the pressure of the inner container  12 , the piston  153  moves so as to expand, in other words, the piston  153  descends. In this moment, the inner pressure of the reference chamber SP decreases. Hence, the push button  154   c  of the aerosol container  154  is pushed, the pressurizing agent P is supplied to the inside of the inner container  12  from the aerosol container  154 . And, when the pressurizing agent P is sufficiently supplied in the inner container  12 , substantially equalizing the pressure of the reference pressure chamber SP and the pressure of the inner container  12 , the piston  153  moves to the original position so as to contract the reference pressure chamber SP by the spring force of the aerosol valve, in other words, the piston  153  ascends. Hence, the push button  154   c  of the aerosol container  154  turns back, and the aerosol valve  154   b  is also shut off. 
         [0346]    In addition, a spring to press the piston  153  downward may be set in the cylinder  152 . Moreover, in place of the piston, a pressure-position transducer such as a diaphragm may be used. 
         [0347]    Next, the assembling method of the discharge container  150  is shown. First, a double container (double bottle) consisting of the outer container  11  and the inner container  12  is molded. In this moment, it is preferable that the inner container  12  is once previously contracted with the guide member etc. so that the concentrate chamber S 1  is securely formed when the content C is filled. Then, the container holder  155  in which the aerosol container  154  is accommodated is housed inside the inner container  12 . Meanwhile, the cap  18  is fixed to the valve holder  17 , and a lid member in which the piston  153  is inserted into the cylinder portion  152  of the valve holder  17  is prepared (refer to  FIG. 35A ). This lid member is fixed to the double container. In this moment, the aerosol container  154  is connected to the cylinder portion  152 , and at the same time, the push button  154   c  of the aerosol container  154  pushes up the piston  153 , the reference pressure chamber SP is sealed and compressed. However, since the pressurizing agent P is not still filled in the inner container  12 , the piston  153  does not ascend higher than the height where the aerosol valve  154   b  of the aerosol container  154  is opened (the state that the push button  154  is somewhat pushed down). Stated differently, as shown in  FIG. 35B , the aerosol valve  154   b  becomes an opened state, the pressurizing agent P is sprayed from the push button  152   c  of the aerosol container  154 , and supplied to the inside of the inner container  12  through the slit  152   a  of the cylinder portion  152  and the slit  155   d  of the container holder  155 . When the inside of the inner container  12  reaches a predetermined pressure, the piston  153  is pushed up to the height where aerosol valve  154   b  is closed, the pressure of the reference pressure chamber SP and the pressure of the inner container  12  substantially balance, the spray of the aerosol container  154  stops (refer to  FIG. 33 ). 
         [0348]    As described above, in the discharge container  150 , the pressurizing agent P can be filled inside the inner container  12  only by assembling, and a special filling facility of the pressurizing agent is not necessary. Moreover, after assembling the discharge container  150 , as later described, the inner pressure of the inner container  12  can be controlled to be constant. 
         [0349]    In addition, the filling of the content C in the accommodating chamber S 1  may be carried out before the valve assembly  101   a  is fixed to the double container, and also it may be filled from the stem  106  after fixing to the double container, opening the valve mechanism  103 . Particularly, in the case that it is carried out before the valve assembly  101   a  is fixed, the double container (the outer container  11  and the inner container  12 ), the aerosol container  154 , and the container holder  155  can be made to be a refill product. When making it to be the refill product, for, example, it is preferable to seal by a lid member  156 , as shown in  FIG. 37C . Thereby, the valve assembly  110   a  etc. can be reused. Moreover, it is possible to replace the aerosol container  154  only. 
         [0350]    Next, the use method of the discharge container is shown. The use method is that, as shown in  FIG. 36A , by the push button etc. (not shown in the figure), the stem  106  is pushed down to open the valve mechanism  103 , the content C can be discharged by the pressure of the inner container  12 . By the discharge of the content C, the inner container  12  expands, decreasing the inner pressure of the inner container  12 , making the pressure adjusting mechanism  151  operate automatically as shown in  FIG. 36B . The pressurizing agent P is supplied to the inside of the inner container  12  from the aerosol container  154 , when the pressure inside the inner container comes into balance with that of the reference pressure chamber SP, the supply of the pressurizing agent P stops automatically. Every time the content C is discharged, since this supply process and supply stop process of the pressurizing agent P is carried out automatically, the content C can be discharged at the same momentum to the last. 
         [0351]    After discharging the content C, as shown in  FIG. 37A , the cap  18  is rotated to ascend the lid member (the pressure adjusting mechanism  151  excepting the container holder  155 ) to the double container (the outer container  11  and the inner container  12 ) and the container holder  155 . In detail, while maintaining the seal structure of the outer seal material A 1 , the lid member is made to ascend so that the inner seal material A 2  held by the inner seal holder  28   a  of the valve holder  17  comes off from the inner surface of the holder body  155   a  of the container holder  155 . Thereby, the seal by the inner seal material A 2  is released, the pressurizing chamber S 2  and the inside of the housing  109  of the valve assembly  101   a  is communicated. Hence, it is possible to induce the pressurizing agent P of the pressurizing chamber S 2  into the housing  109  without discharging to the exterior. After that, by pushing down the stem  106  by push button etc. the pressurizing agent P can be discharged to the exterior safely (refer to the thick arrow of  FIG. 37A ). In this moment, since the inner pressure of the pressurizing chamber S 2  becomes lower than the inner pressure of the reference pressure chamber SP, the piston  153  descends, and the aerosol container  154  is also opened. Hence, the pressurizing agent P inside the gas container (the aerosol container  154 ) can be exhausted to the last. In addition, when the aerosol container  154  is not fixed to the holding claw  152   a  of the cylinder portion  152 , as shown in  FIG. 37B , the aerosol container  154  is supported to the bottom portion  155   c  of the container holder  155 . 
         [0352]    Moreover, the piston  153  descends and goes across the slit  152   a . Hence, the reference pressure chamber SP and the pressurizing chamber S 2  are communicated, the pressuring chamber S 2  can be exhausted without exhausting the pressurizing agent P of the aerosol container  154  (refer to the thick arrow of  FIG. 37B ). In this case, the aerosol container  154  can be reused. 
         [0353]    The discharge container  150   a  of  FIG. 38  is different to the discharge container  150  of  FIG. 32  in the point that the container holder is omitted, and the aerosol container  154  is placed in the bottom portion of the inner container  12 . In detail, it is provided with the outer container  11 , the inner container  12  accommodated therein, the valve assembly  101   a  closing the outer container  11  and the inner container  12 , and the pressure adjusting mechanism  151   a  to adjust the inner pressure of the inner container, being accommodated in the inner container. The pressure adjusting mechanism  151   a  is attached to the lower end of the valve assembly  13 . The outer container  11  and the inner container  12  are substantially same as the discharge container  100  of  FIG. 21 , the content C is filled in the accommodating chamber S 1  between the outer container  11  and the inner container  12 , the pressurizing agent P is filled in the pressurizing chamber S 2  inside the inner container. The valve assembly  101   a  is substantially same other than that the cylinder portion  152  is made to be longer than the cylinder portion  152  of the valve assembly  101   a  of the discharge container  150  of  FIG. 32 . In addition, the length of the cylinder portion  152  of  FIG. 38  may be made to be same as that of the cylinder portion  152  of  FIG. 32 , the pressure resistant container of the aerosol container  154  may be lengthened. The inner seal material A 2  held in the inner seal holding portion  28   a  of the plug portion  28  of the valve assembly  101   a  is compressed between the bottom potion of the inner seal holding portion  28   a  and the inner cylindrical portion  12   a  of the inner container  12 , and seals between the pressurizing chamber S 2  and the valve assembly  101   a.    
         [0354]    The pressure adjusting mechanism  151   a  is provided with the above described cylinder portion  152 , the piston  153  accommodated inside the cylinder portion  34 , and the aerosol container (gas container)  154  in which a high pressure gas is filled, being inserted into the lower end of the cylinder portion  153 , the aerosol container  154  being placed in the bottom portion of the inner container  12 . The piston  153  and the aerosol container (gas container)  154  are substantially same as the pressure adjusting mechanism  151  of  FIG. 32 . And, in the pressure adjusting mechanism  151   a , the space inside the cylinder portion  152  serves as the reference pressure chamber SP, the inside of the aerosol container  154  serves as the high pressure chamber HP, the valve of the aerosol valve  154  serves as a valve. This pressure adjusting mechanism  151   a  also, same as the pressure adjusting mechanism  151  of the discharge container of  FIG. 32 , operates according to the pressure difference of the pressure of the reference pressure chamber SP and the pressure of the inner container  12  (the pressurizing chamber S 2 ). In order to place the aerosol container  154  in the inner container  12 , as later described, the aerosol container  154  is placed in the inner container  12 , and after that, by attaching the valve assembly  101   a , it can be assembled. In this occasion, the cylinder portion  152  and the aerosol container  154  are easy to be connected. 
         [0355]    The assembling method of the discharge container  150   a  is shown below. 
         [0356]    First, a double container consisting of the outer container  11  and the inner container  12  is molded. Then, the aerosol container  154  is housed inside the inner container  12 . Meanwhile, the cap  18  is fixed to the valve holder  17 , and a lid member in which the piston  153  is inserted into the cylinder portion  152  of the valve holder  17  is prepared (refer to  FIG. 39A ). This lid member is fixed to the double container. In this moment, the aerosol container  154  is connected to the cylinder portion  152 , and at the same time, the push button  154   c  of the aerosol container  154  pushes up the piston  153 , the reference pressure chamber SP is sealed and compressed (refer to  FIG. 39B ). Same as the discharge container  150  of  FIG. 32 , the aerosol valve  154   b  of the aerosol container  154  opens at the same time, the pressurizing agent P is supplied to the inside of the inner container  12  from the push button  154   c  of the aerosol container  154 . When the inside of the inner container  12  reaches a predetermined pressure, the piston  153  is pushed up to the height where the aerosol valve  154   b  closes, the pressure of the reference pressure chamber SP and the pressure in the inner container  12  substantially balance, the spray of the aerosol container  154  stops. 
         [0357]    In this discharge container  150   a  also, as described above, same as the discharge container  150  of  FIG. 1 , the pressurizing agent P can be filled inside the inner container  12  by only assembling, making a special filling facility unnecessary. Moreover, after assembling the discharge container  150   a , as later described, the inner pressure of the inner container  12  can be controlled to be constant. In addition, the filling of the content C in the concentrate chamber S 1  may be carried out either before and after the fixing of the valve assembly  101   a  to the double container. In this discharge container  150   a  also, the outer container  11 , the inner container  12 , the aerosol container  154 , and the content C filled in the concentrate chamber S 1  can be made to be a refill product. In the case that it is made to be refill product, same as the discharge container  150  of  FIG. 32 , it is preferable to seal with the lid member  156  as shown in  FIG. 36 . 
         [0358]    In addition, in the discharge container  150   a  of  FIG. 38 , the aerosol container  154  is placed in the bottom portion of the inner container  12 , but it may be hanged in the inner container  12  without being supported by the bottom portion of the aerosol container  154 . 
         [0359]    The discharge container  160  of  FIG. 40  is that in which a check valve for concentrate which shuts off a fluid going to the accommodating chamber S 1  from the exterior and let through the fluid going to the exterior is provided in the discharge passage between the accommodating chamber S 1  and atmospheric air. In detail, it is provided with the outer container  11 , the inner container  12  accommodated in the outer container  11 , and a valve assembly  161  closing the outer container  11  and the inner container  12 , in which the above described check valve for concentrate is provided. The outer container  11  and the inner container  12  are substantially same as those of the discharge container  100  of  FIG. 21 , the content C is filled in the accommodating chamber S 1  between the outer container  11  and the inner container  12 , the pressurizing agent P is filled in the pressurizing chamber S 2  inside the inner container. The valve assembly  161  has the concentrate passage Z 1  (refer to  FIG. 42A ) which communicates the accommodating chamber S 1  and the exterior, and the gas passage Z 2  (refer to  FIG. 42B ) which communicates the pressurizing chamber S 2  and the exterior. And, in the concentrate passage Z 1 , a check valve  163  for concentrate which shuts off the fluid going to the accommodating chamber S 1  from the exterior, and let through the fluid going to the exterior from the accommodating chamber S 1  is provided. In the gas passage Z 2 , a check valve  164  for gas which shuts off the gas going to the exterior from the pressurizing chamber S 2 , and let through the gas going to the pressurizing chamber S 2  from the exterior is provided. 
         [0360]    The valve assembly  161  is, as shown in  FIG. 41A , has a valve holder  165  arranged so as to close the opening of the outer container  11  and the inner container  12 , having a first communicating hole  165   a  (the concentrate passage Z 1 ) communicating the exterior and the accommodating chamber S 1 , and a second communicating hole  165   b  communicating the exterior and the pressurizing chamber S 2 , the valve mechanism  103  accommodated in the valve holder  17 , an annular moving valve  166  (the check valve  163  for concentrate) opening/closing the concentrate passage Z 1 , an elastic valve  167  (the check valve  164  for gas) opening/closing the gas passage Z 2  (the son communicating hole  165   b ), and a cap  168  which holds the valve mechanism  106  in the valve holder  165 , and fixes the valve holder  165  to the outer container  11 . The valve mechanism  106  is substantially same as the discharge container  100  of  FIG. 21 . 
         [0361]    The valve holder  165  is, as shown in  FIG. 41B , is provided with a cylindrical valve housing  171  in which a first communicating hole  165   a  is formed in the side surface, a second communicating hole  165   b  is formed in the side surface lower than the first communicating hole  165   a , and an annular support flange  172  provided in the outer periphery of the valve housing  171  so as to protrude outward radially. 
         [0362]    The valve holder  165  is molded by injection molding etc. from synthetic resin such as polypropylene, polyacetal, polyethylene terephthalate. 
         [0363]    The valve housing  171  comprises a cylindrical housing body  173  in which the valve mechanism  106  is accommodated, and a cylindrical gas supply portion  174  protruding downward so as to communicate with the housing body  173 . 
         [0364]    The housing body  173  has a rubber holding portion  173   a  supporting the stem rubber  107  of the valve mechanism  106  provided in the upper end thereof, a plurality of the first communicating holes  165   a  provided radially in the side surface at an equal interval, an annular bottom portion  173   b  provided beneath the first communicating hole  165   a . Moreover, in the upper outer periphery spaced upper than the first communicating hole  165   a , an annular engaging groove  173   c  engaging with the cap  168  is formed. The first communicating hole  165   a  is provided more than two, for example, 2-8. The gas supply portion  174  is a cylindrical body in which the second communicating hole  165   b  is provided, and is a portion to which the elastic valve  167  is attached, and communicates with the annular bottom portion  173   b  of the valve holding portion  174 . In detail, the outer shape is that in which a large diameter portion  174   a , a medium diameter portion  174   b , a small diameter portion  174   c  are provided coaxially beginning at the top. The lower portion of the small diameter portion  174   c  is closed, and the second communicating hole  165   b  is formed in the side surface thereof. By forming the outer shape with a plurality of step portions as the large diameter portion  174   a , the medium diameter portion  174   b , the small diameter portion  174   c , the falling off of the elastic body  167  is prevented. The outer surface of the gas supply portion  174  (for example, the outer surface of the medium diameter portion  174   b  and the lower surface of the large diameter portion  174   a ) and the inner surface of the elastic valve  167  (for example, the medium diameter portion  167   b  and flange portion  167   c ) may be adhered by an adhesive etc. so that the second communicating hole  165   b  opens to the fluid going to the pressurizing chamber S 2  from the gas supply portion  174 . 
         [0365]    The support flange  172  is provided with a cylindrical valve guide portion  172   a  extending downward from the first communicating hole  165   a  of the valve housing, and an annular flange portion  172   b  extending outward radially from the lower end thereof, and a cylindrical seal material holding portion  172   c  extending downward from the central lower surface of the flange portion  172   b.    
         [0366]    The moving valve  166  is arranged in the outer periphery of the valve guide portion  172   a . The moving valve  166  moves vertically in the outer periphery of the valve guide portion  172   a . Moreover, in the lower end inner surface of the valve guide portion  172   a , an annular engaging protrusion  172   a   1  engaging with the tip of the flange portion  167   c  of the later described elastic valve  167  is provided. 
         [0367]    In the upper surface of the flange portion  172   b , a plurality of the lateral passage grooves  27   a  is provided radially at an equal interval. The number of this lateral passage grooves  27   a  is made to be the same as that of the longitudinal passage groove  12   c  of the inner container  12 , and it is positioned at the same angle with the longitudinal passage groove  12   c  at planar view. Thereby, the lateral passage grooves  27   a  and the outer end side of the flange portion  172   b  compose a part of the above described concentrate passage Z 1 , and are communicated with the longitudinal passage groove  12   c  of the inner container  12  (refer to  FIG. 42 ). 
         [0368]    Moreover, the flange portion  172   b  is composed so that the outer diameter is made to be somewhat smaller than the outer diameter of the flange portion  12   b  of the inner container  12  (refer to  FIG. 40 ). Thereby, the gap G 2  is made to be formed in the outer periphery of the flange portion  172   b , and is easy to be communicated with the lateral passage grooves  27   a.    
         [0369]    However, it may be substantially same as the outer diameter of the flange portion  12   b  of the inner container  12 . In this case, the inner surface diameter of the cap  168  is adjusted so that the gap G 2  is formed in the outer periphery of the flange portion  12   b.    
         [0370]    And, a seal locking portion  172   d  protruding downward is formed in the outside of the seal material support portion  172   c , being the lower surface of the flange portion  172   b.    
         [0371]    A ring like seal material A 2  is arranged in the outer periphery of the seal support portion  172   c  (refer to  FIG. 40, 42 ). This seal material A 2  is a member to seal between the inner container  12  and the exterior by being compressed vertically. In this embodiment, the outer surface of the valve guide portion  172   a  and the outer surface of the valve housing  171  (gas supply portion  174 ) is made to be inside and outside surfaces provided coaxially, but it may be made to be an identical surface, for example, as shown in  FIG. 46 . As this embodiment, by making the gas supply portion  174  of the valve housing  171  to be reduced in diameter than the valve guide portion  172   a  and to be provided inside, it becomes possible to miniaturize the valve holder  165  wholly. 
         [0372]    The moving valve  166  is, as shown in  FIG. 41C , a ring like cylindrical body. In the inside and outside surface of the upper portion, an annular skirt portion  166   a  formed to be taper like so as to expanded in diameter upward is formed. The cross section thereof presents an approximate Y character. Moreover, in the lower end inner surface, an annular notched portion  166   b  formed taper like so as to be reduced in diameter upward is formed. Further, in the center of the upper end surface, an annular groove  166   c  is formed. 
         [0373]    In the moving valve  166 , the skirt portion  166   a  slightly bends so as to close the annular groove  166   c  against a fluid flowing from underneath, the skirt portion  166   a  slightly bends so as to open the annular groove  166   c  against the fluid flowing from above. Since being composed as described above, the fluid from above is stopped and the fluid from underneath is let through. The moving valve  166  like this is molded from, for example, synthetic resin such as low molecular mass poly ethylene, and silicone rubber etc. 
         [0374]    The elastic valve  167  is that which covers the outer periphery of the above described gas supply portion  174 . In detail, as shown in  FIG. 41D , it is provided with a small diameter portion  167   a  covering the small diameter portion  174   c  of the gas supply portion  174 , a medium diameter portion  167   b  covering the medium diameter portion  174   b  of the gas supply portion  174 , being continuous with the small diameter portion  167   a , and a flange portion  167   c  arranged along the lower surface of the large diameter portion  174   a  of the gas supply portion  174 . The tip of the flange portion  167   c  engages with the engaging protrusion  172   a   1  of the support flange  172  of the valve holder  165 . In addition, the shape of the elastic valve  167  may be selected according to the shape of the gas supply portion  174  taking into consideration the attaching state to the gas supply portion  174 . Being composed as described above, against the fluid going to the exterior (inside the inner container  12 ) of the gas supply portion  174  from the second communicating hole  165   b  of the gas supply portion  174 , the small diameter portion  167   a  deforms so as to expand, letting through the fluid to the exterior of the gas supply portion  174 , against the fluid going to the second communicating hole  165   b  from the exterior of the gas supply portion  174 , the gas supply portion  174  disturbs the deformation of the elastic valve  167  to stop the fluid. The elastic valve  167  is molded from, for example, the rubber such as nytril rubber, butyl rubber, silicone rubber. 
         [0375]    The cap  168  is, as shown in  FIG. 41A , comprises a cylindrical cover portion  176  covering the valve holder  165 , and a fixing portion  177  attached to the outer container  11 . The cover cap  168  forms the gap G 1  with the inside surface thereof and the outer surface of the valve holder. 
         [0376]    The cover cap  168  is molded by the injection molding of synthetic resin, for example, such as polyacetal, polybutylene terephthalate. 
         [0377]    The cover portion  176  comprises a circular plate like top surface  181 , a cylindrical valve fitting portion  182  extending downward from the edge portion thereof, and a cylindrical diameter-expanded portion  183  extending downward, being expanded in diameter than the valve fitting portion  182 . In the top surface  181 , a center hole  181   a  to let through the stem  109  is formed. In the lower portion of the valve fitting portion  182 , an annular engaging protrusion  182   a  protruding inward radially is formed. This engaging protrusion  182   a  engages with, as described above, the annular engaging groove  173   c  of the valve holder. Thereby, the valve holder  165  is fixed to the cover cap  168 . 
         [0378]    The diameter-expanded portion  183  is a portion, the inner surface of which is expanded in diameter than the inner surface of the valve fitting portion  182 . Stated differently, between the inner surface of the diameter-expanded portion  183  and the valve guide portion  172   a  (the outer periphery of the valve housing  171 ) of the valve holder  165 , the cylindrical gap G 1  extending vertically is formed. Moreover, a first step portion  183   a  between the valve fitting portion  182  and the diameter-expanded portion  183  becomes upper than the first communicating hole  165   a  at intervals. The space G 1  consists of an evacuation passage space G 1   a  upper side than the first communicating hole  165   a , and a passage space G 1   b  lower side than the first communicating hole  165   a . And, the evacuation passage space G 1   a  serves as an evacuation passage, the passage space G 1   b  serves as a part of the concentrate passage Z 1  (refer to  FIG. 42A, 42B ). 
         [0379]    The fixing portion  177  is, as shown in  FIG. 41A , presents a shape expanded in diameter from the cover portion  176  thereof. In detail, it comprises a ring like medium top face  186  extending outward radially from the lower end of the diameter-expanded portion  183  and a cylindrical locking cylinder portion  187  extending downward from the edge portion thereof. The diameter of the inner surface of the locking cylinder portion  187  is made to be larger than the diameter of the outer end of the flange portion  172   b  of the valve holder  165 . The lower surface of the medium top face  186  is arranged so as to contact the upper surface of the flange portion  172   b  of the valve holder  165 . However, as described above, a plurality of passages is formed radially at an equal interval by the lateral passage groove  27   a  formed in the flange portion  172   b . In addition, this lateral passage groove may be formed in the lower surface of the medium top face  186 . This lateral passage groove  27   a  is, as described above, arranged so as to communicate with the longitudinal passage groove  12   a . Moreover, in the inner surface of the locking cylinder portion  187 , a screw  187   a  engaging with the screw  11   a  of the outer container  11  is formed. Further, beneath the screw  187   a , an inner cylindrical portion  187   b  expanded in diameter is formed so as to cover the seal holding portion  11   b , and it compresses radially the outer seal material (O ring) A 1  held by the outer seal material holding portion  11   b  of the outer container  11  between the outer surface of the neck portion of the outer container and the inner cylinder portion  187   b , and seals between the outer container  11  and the exterior (refer to  FIG. 40 ). 
         [0380]    The concentrate passage Z 1  of the valve assembly  161  is, as shown in  FIG. 42A , passes through the inside of the housing body  173  from the stem  106  communicating with the exterior, goes out to the exterior of the valve housing  171  from the first communicating hole  165   a , and reaches to the passage space G 1   b  (lower side than the first communicating hole  165   a  between the valve holder  165  and the cap  168 ), the lateral passage groove  27   a , and the gap G 2  of the outside of the flange portion  172   b  of the valve holder. 
         [0381]    Stated differently, the concentrate passage Z 1  consists of the stem  106  of the valve mechanism, the inside of the valve housing  171  of the valve holder  165 , the first communicating hole  165   a , the passage space between the outer periphery of the valve housing  171  and the cover cap  168 , and the passage (the gap G 2  of the lateral passage groove  27   a  and the outside of the support flange) between the support flange  172  of the valve holder and the cover cap  168 . And, this concentrate passage Z 1  communicates with the accommodating chamber S 1  between the outer container  11  and the inner container  12  through the longitudinal passage groove  12   c.    
         [0382]    The check valve for concentrate  163  of the concentrate passage Z 1  consists of the passage space G 1   b  which is a part of the concentrate passage Z 1  (lower side than the first communicating hole  165   a  between the valve holder  165  and the cover cap  168 ), the evacuation passage space G 1   a  being the evacuation passage (upper side than the first communicating hole  165   a  of the gap G 1   a  between the valve holder  165  and the cap  168 ) and the moving valve  166  accommodated in the gap G 1 . Stated differently, when the fluid going to the accommodating chamber S 1  from the exterior is supplied to the concentrate passage Z 1 , the skirt portion  166   a  of the moving valve  166  slides inside the space G 1 , and moves to the passage space G 1   b  side (refer to  FIG. 42B ). After that, the fluid presses the annular groove  166   c  of the moving valve  166  supported to the flange  172   b , the skirt portion  166   a  bends slightly so as to open the annular groove  166   c , and seals the concentrate passage Z 1 . Meanwhile, when the fluid going to the exterior from the accommodating chamber S 1  is supplied to the concentrate passage Z 1 , since the skirt portion  166   a  receives pressure from below, the annular groove  166   c  bends slightly to so as to close, the seal across the space G 1  is released, or becomes to be slidable, and it slides in the space G 1  and moves to the evacuation passage G 1   a  side. Thereby, the concentrate passage Z 1  becomes communicated. 
         [0383]    Meanwhile, the gas passage Z 2  of the valve assembly  161  is, as shown in  FIG. 42B , reaches to the second communicating hole  165   b  from the gas supply portion  174 , passing through inside the housing body  173  from the stem  106  communicated with the exterior. 
         [0384]    In other words, this gas passage Z 2  consists of the stem  106 , the inside of the valve housing  171  of the valve holder  65  of the valve assembly  161 , and the second communicating hole  165   b.    
         [0385]    And, this gas passage Z 2  is communicated with the pressurizing chamber S 2  directly. 
         [0386]    The check valve  164  for gas of the gas passage Z 2  consists of the gas supply portion  174 , the second communicating hole  165   b  thereof, and the elastic valve  167 . Stated differently, the fluid going to the pressurizing chamber S 2  from the exterior is supplied to the gas passage Z 2 , the small diameter portion  167   a  of the elastic valve  167  deforms to open the second communicating hole  165   b . Meanwhile, the fluid going to the exterior from the pressurizing chamber S 2  is supplied to the gas passage Z 2 , the outer periphery surface of the gas supply portion  174  disturbs the deformation of the elastic body  167 , the second communicating hole  165   b  is maintained to be in the state being closed by the elastic valve  167 . 
         [0387]    Next, the filling process of the concentrate and the pressurizing agent into the two-layer discharge container  160  is shown in  FIG. 43 . 
         [0388]    As shown in  FIG. 43A , the outer container  11  and the inner container  12  are molded, and the concentrate C is filled between the outer container  11  and the inner container  12  (the accommodating chamber S 1 ). Thereby, the inner container  12  is crushed (refer to  FIG. 43B ). In this moment, as described above, it is preferable to carry out the filling after contracting the inner container  12  previously using the guide member. 
         [0389]    Next, the valve assembly  161  is fixed to the outer container  11  and the inner container  12 . 
         [0390]    After that, as shown in  FIG. 43B , it is manufactured so that at the same time with the pushing down of the stem  106 , the pressurizing agent P is filled in the pressuring chamber S 2  from the stem  106  through the gas passage Z 2 . In this moment, the pressurizing agent P is also supplied to the first communicating hole  165   a , but as described above, since the moving valve  166  of the check valve  163  for concentrate shuts off the concentrate passage Z 1 , the pressurizing agent P is not filled in the accommodating chamber S 1  (refer to Z 2 ′ of  FIG. 42B ). Once, the pressurizing agent P is filled in the pressurizing chamber S 2 , the inside of the pressurizing chamber S 2  becomes higher pressure than the exterior. Hence the pressurizing agent P tends to go to the exterior. But, the check valve for gas  164  shuts off the passage Z 2  for gas (the second communicating hole  165   b ), the flowing back of the pressurizing agent P is prevented. 
         [0391]    The use state of this two-layer discharge container  160  is shown in  FIG. 44A, 44B . 
         [0392]    As shown in  FIG. 44A , by the operation of pushing down the stem  106 , the concentrate C is discharged to the exterior through the concentrate passage Z 1 . Meanwhile, when the concentrate C of the accommodating chamber S 1  is discharged wholly, as shown in  FIG. 44B , the inner container  12  expands, to contact tightly the inner surface of the outer container  11 . Particularly, in this two-layer discharge container  160 , in the case that the outer container  11  and the inner container  12  are made to be transparent or translucent, since the inner container  12  has substantially the identical shape with the inner surface of the outer container  11 , and the space between the outer container  11  and the inner container  12  serves as the accommodating chamber S 1 , when using that which is opaque, particularly cream as the concentrate C, the appearance of the outer container varies suddenly in the conditions between the state that the concentrate C remains and the state the concentrate C does not remain. Stated differently, when the concentrate C remains in the accommodating chamber S 1 , in the outer container  11 , the presence of the concentrate C can be identified, when the concentrate C disappears from the inside of the accommodating chamber S 1 , the outer container  11  becomes transparent suddenly. Hence, the run out of the concentrate C can be visually identified. 
         [0393]    Moreover, after discharging the concentrate C wholly, by turning the cap  168 , it can be separated into each part. Particularly, since it is provided with the inner seal material A 2  which seals by compressing between the inner container  12  and the valve assembly  13  vertically, and the outer seal material A 1  (O ring) which seals by compressing between the outer container and the valve assembly right and left (horizontally), and since the cap  168  is made to be screw type, when the cap  168  is loosened by turning in the direction of unsealing, the seal of the inner seal material A 2  can be released while maintaining the seal of the outer seal material A 1  (temporary fixing). 
         [0394]    Stated differently, the pressurizing agent P in the inner container  12  opens the check valve for concentrate  163 , passing through a part (the outer periphery of the flange portion  172   b  of the valve holder  165 , the lateral passage groove  27   a , the space G 1 ) of the concentrate passage Z 1 , the pressurizing agent P can be discharged to the exterior from the stem  106  by operating the valve assembly  161 . 
         [0395]    Moreover, even in the case that consumers loosen the cap  168  accidently in a state that the concentrate C remains in the accommodating chamber S 1 , since the seal between the outer container  11  and the cap  168  is maintained by the outer seal material A 1 , the concentrate C does not spout from the lower end of the cap  168 .
