       DESCRIPTION OF THE INVENTION 
     Problems to be Solved 
       [0005]    However, in the case where the part of the container body below the bead portion is tapered like shown in container of Patent Document 1, there is a possibility that the cover cap come off due to the weak engagement force between the container body and the cover cap of the valve assembly in which the cover cap is clinched to the bead portion. Further, because the sealing member is provided between the container body and the cover cap, the sealing force decreases in tandem with the engaging force. 
         [0006]    Moreover, in the case where the sealing member is provided on the inner surface of the bead portion like shown in FIG. 13 of Patent Document 2, there is a problem that the wrinkle formed on the inner surface of the bead portion during the forming of the container body forms the pathway for the propellant to be leaked from the container body, even if the sealing member is pressed to the inner surface of the bead portion. Specifically, while the bead portion is formed by applying the necking processing to the upper part of the barrel portion to reduce the diameter of the neck portion and applying the curling processing to the top of the neck portion, the wrinkle is formed on the inner surface of the neck portion or the synthetic resin coating of the neck portion while the necking processing. Further, the wrinkle formed on the necking processing is further deepened at the curling processing. Because, the sealing member is already provided on the inner surface of the bead portion when it is formed, the deformation amount of the sealing member can not be controlled according to the condition of the bead portion formed on the container body. 
         [0007]    The first aspect of the present invention is directed to the discharge container having high sealing property where it is formed by firmly fixing the valve assembly to the container body made of metal having the bead. 
         [0008]    The second aspect of the present invention is directed to the passage member and the discharge container using the same in which the remaining amount at the end is small because the pathway for the content is secured even if the content is lessen and the pouch shrunk.

       Effect of the Invention 
       [0026]    In the discharge container of the present invention, because it is equipped with a container body made of metal having an opening, and a valve assembly fixed to the opening of the container body; where the opening has a cylindrical portion and a bead portion formed above the cylindrical portion, where the valve assembly has a plug portion inserted into the opening, a valve structure which opens and closes a pathway of a content and is fixed to the plug portion, a sealing member provided on an outer surface of the plug portion, and a cover cap fixing the valve assembly to the container body; where the cover cap has an upper portion covering the plug portion and the valve structure and a plastic deformation portion fixed to the bead portion by deforming in a central direction; and where the sealing member contacts with a part of the cylindrical portion lower than the plastic deformation portion and seals a gap between the container body and the plug portion, the outer diameter of the part of the cylindrical portion which contacts with the sealing member can be controlled when deforming the lower part of the cover cap. In other word, the sealing property of the sealing structure can be controlled at the final stage of the manufacturing process. Therefore, sealing structure having high durability and having high accuracy can be obtained. Further, the fixture of the container body and the cover cap is accomplished between the bead portion of the container body and the cover cap, and the sealing between the container body and the cover cap is accomplished between the cylindrical portion of the container body and the plug portion, that is to say the fixing structure and the sealing structure are independent with each other. Therefore, the process is simple. Moreover, because the opening of the container has the cylindrical portion and the bead portion formed above the upper side of the cylindrical portion, the lower part of the cover cap can be deformed deeply against the cylindrical portion, resultantly, the container body and the valve assembly can be strongly fixed. 
         [0027]    In the discharge container where the container body has a cylindrical barrel portion, a neck portion having diameter small than the barrel portion, and a bead portion formed on top of the neck portion, the sealing property is high, even if the wrinkle is formed on the inner surface of the neck portion or the synthetic resin coating formed on the inner surface of the neck portion when forming the neck portion during necking process. That is because, the sealing can be formed by controlling the outer diameter of the part of the cylindrical portion contacting with the sealing member. Note that when the synthetic resin coating is provided on the inner surface of the neck portion after forming the neck portion or necking process, the sealing property which can seal the propellant can not be obtained reproductively. 
         [0028]    In the case where the valve assembly has the valve holder which holds plural of valve structures and where the plug portion is formed on the outer surface of the valve holder, plural of contents can be stored and plural of stored contents can be independently discharged by providing plural of valve structure. 
         [0029]    In the case where the valve structure is housed in a housing configuring the pathway, where the valve structure is united with the housing by a cap covering the housing, and where the housing is fixed to the plug portion, the sealing property of the valve structure can be secured by fixing the valve structure to the housing with the cap. Therefore, the sealing property is high. In the case where the sealing property of the valve structure is obtained by fixing the valve structure to the housing with the cover cap like shown in Patent Document 1, the performance of the valve structure will be depend on the engaging force of the cover cap to the container body, and the production process will be cumbersome. 
         [0030]    In the case where the valve structure is housed in a penetrating hole of the plug portion configuring the pathway, although the production process will be cumbersome, the downsizing of the valve assembly is possible and use of the material can be reduced. 
         [0031]    In the discharge container of the present invention having a pouch housed in the container body and a joint member connecting the pouch and the valve assembly, and where the joint member has a tubular valve connecting portion which is fixed to the valve assembly, a tubular pouch fixing portion concentrically provided on a lower end of the valve connecting portion which is fixed to the an opening of the pouch, and a guiding portion extending to a bottom portion of the pouch from a lower end of the pouch fixing portion which is to guide the content into the pouch fixing portion, and where the guiding portion has a main body extending in vertical direction, a communicating portion provided on an upper end of the main body which is to communicates a surface of the main body with a center hole of the pouch fixing portion, and a projecting portion projecting from the main body, and where the projecting portion is equipped with at least two main projections formed concentrically line and formed apart in vertical direction, even when the remaining of the content become small and the pouch shrunk, the flow passage of the content to the center hole of the pouch fixing portion in the pouch is secured, the content can be discharge till the last. 
         [0032]    In the discharge container of the present invention where the valve assembly is equipped with a valve holder having the plug portion retaining the valve structure which is to be inserted into the opening of the container body, and a flange portion arranged on an upper end of the opening of the container body, and where the cover cap covers the valve holder and fixes the valve holder to the container body, and a portion covering the valve holder is formed with a penetrating hole, the propellant which is accumulated between the valve holder and the cover cap can be ejected through the penetrating hole. 
         [0033]    The present invention of a method for manufacturing the discharge container where the sealing member is being brought into contact with the cylindrical portion by inserting the plug portion of the valve assembly into the container body, where the valve assembly is fixed to the container body by plastically deforming a lower portion of the cover cap of the valve assembly with clinch claws depressing in center direction, and at the same time, where the outer diameter of the cylindrical portion of the container body is controlled by the tips of the clinch claws, the deforming amount of the sealing member can be controlled at the last stage of the manufacturing method, therefore, the product having high durability of the sealing property and accurate product can be constantly produced. 
         [0034]    In the second aspect of the discharge container of the present invention, because it is equipped with a container body having a pressure resistance, a pouch housed in the container body, a valve assembly fixed to an opening of the container body, and a joint member connecting the valve assembly and the pouch; where the joint member has a tubular valve connecting portion which is fixed to the valve assembly, a tubular pouch fixing portion concentrically provided on a lower end of the valve connecting portion which is fixed to an opening of the pouch, and a guiding portion extending to a bottom portion of the pouch from a lower end of the pouch fixing portion which is to guide the content into the pouch fixing portion; where the guiding portion has a main body extending in vertical direction, a communicating portion provided on an upper end of the main body which is to communicate a surface of the main body with a center hole of the pouch fixing portion, and a projecting portion projecting from the main body; and where the projecting portion is equipped with at least two main projections formed concentrically and formed apart in vertical direction, even when the remaining of the content become small and the pouch shrunk, the flow passage of the content to the center hole of the pouch fixing portion in the pouch is secured, and the content can be discharged till the last. Particularly, because the projecting portion projected from the main body is equipped with at least two main projections formed concentrically and formed apart in vertical direction, the surface area of the whole guiding portion still increased due to the asperity formed on the main body, and the space between the pouch and the guiding portion tends to be formed when the pouch shrunk. Especially, the space of the flow path tends to be form between the foot of the main projection and the pouch, parallel with the main projection. Further, a large flow path is secured with a space formed on the surface (surface of the main body of the guiding portion) between vertically adjacent main projections. Further, the flow path generated by the main projections and the planar space are concentrically formed, the contents can be guided efficiently. 
         [0035]    In the third aspect of the discharge container of the present invention, because it is equipped with a container body having pressure resistance and a valve assembly for an aerosol fixed on an opening of the container body; where the valve assembly has a valve structure which communicates an atmosphere with the container body when operated, a valve holder equipped with a plug portion inserted into the opening of the container body and a flange portion provided on a top of the opening of the container body, and a cover cap which covers the valve holder and which fixes the valve holder to the container body; where a gap between the valve holder and the opening of the container body is seated; and where a penetrating hole is formed on a part of the cover cap which covers the valve holder, the propellant intruded between the valve holder and the cover cap during the under-cup charging which charges the propellant into the container body through the gap between the container body and the valve holder, can be ejected through the penetrating hole. Therefore, the difference between the ejection of the intruded propellant and the leak of the propellant due to the defect assembling of the valve assembly can be easily detected, so the propellant leak test can be operated accurately.

         [0051]    The valve holder  16  has, like shown in  FIG. 2   a ,  2   b , a plug portion  21  inserted into the opening of the container body  11 , a flange portion  22  which is projected radially outwardly from the upper end of the plug portion  21  and which is provided above on the bead portion  11   d  of the container body  11 , and a lid portion  23  projected upwardly from the upper surface of the flange portion  22 . In the valve holder  16 , there are two penetrating holes  24  which vertically penetrates the plug portion  21  the flange portion  22 , and the lid portion  23 . The aerosol valve  17  is inserted into the penetrating hole  24  and is fixed to the valve holder with the cover cap  19 . 
         [0052]    On the outer surface of the plug portion  21 , an annular recessed portion  21   a  for holding the O-ring  18  is formed. The bottom of the recessed portion  21   a  (lateral surface of plug portion) is formed to be vertical plane. The position of the recessed portion  21   a  is designed so as the O-ring  18  held by the recessed portion  21   a  is in contact with the neck portion (cylindrical portion) of the opening of the container body  11 , when the lower part of the cover cap is clinched to the container body  11  from the outside. In this embodiment, it is provided on the lower part of the plug portion  21 . 
         [0053]    The lid portion  23 , like shown in  FIG. 1   b  and  FIG. 2   b  has a cross sectional arc shape where a notch portion  23   a  of a fan shape is trimmed from the circle, to verify the direction of entire container. 
         [0054]    Two penetrating holes  24  are formed in a line parallel with the notch portion  23   a  of the lid portion  23  and opposing to each other, The penetrating hole  24  has a support step port on  26  having a tapered shape which extends downwardly reducing the diameter. The shape of the support step portion  26  is not limited as long as it can hold the aerosol valve  17  discussed below. 
         [0055]    On top of the support step portion  26 , an inside inner surface  17  which continues from the support step portion  26  is formed. On the outside of inside inner surface  27 , an outside inner surface  29  is formed across the annual channel portion  28 . The inside inner surface  27  has a contacting surface  27   a  having tubular shape, a reduced diameter step portion  27   b  formed on top of the contacting surface, and a sealing portion  27   c  having tubular shape contacts with the O-ring  35  sealing a gap between the aerosol valve  17  and the penetrating hole  24 . However, the reduced diameter step portion  27   b  may be omitted and have the abutting surface  27   a  and the sealing portion  27   c  to be combined. 
         [0056]    On the bottom of the support step portion  26 , a lower inner surface  30  having tubular shape extending downwardly is provided, and on its lower side, an engaging claw  30   a  projecting in inner side of the radial direction is provided. The engaging claw  30   a  is formed to hold the joint member  42  which connects the valve holder  16  and the inner container  13 . For the alternative of the engaging claw  30   a,  it may be designed to have the lower inner surface  30  and the tubular joint member  42  to fit with each other. 
         [0057]    The aerosol valve  17 , shown in  FIG. 2   c , is an assembly which united a housing  31  having a tubular shape, a valve structure  32  housed in the housing  31 , and a cap  33  covering the housing  31  and fixing the valve structure  32  to the housing  31 . The housing  31  of the aerosol valve  17  works as a pathway of the content, and the valve structure  32  opens and closes the housing. The housing  31  of the aerosol valve  17  is inserted in the penetrating hole  24  of the valve holder  16 , and the aerosol valve  17  is fixed to the valve holder  16 . 
         [0058]    The housing  31  is a tubular object having a bottom, where a tubular joint portion  31   a  is formed on the lower end extending downwardly, where a holding step  31   b  holding the valve structure  32  is formed on the top of the inner surface, and where a projecting portion  31   c  is formed on the top of the outer surface projecting in radially outwardly direction.

The bottom of the recessed portion  31   d  (lateral surface of plug portion) is formed to be vertical plane. Moreover, an annular step portion  31   e  where the diameter decreases downwardly, is formed on the lower side of the recessed portion  31   d.  Therefore, when the aerosol valve  17  is inserted into the penetrating hole  24 , the annular step portion  31   e  engages with the support step portion  26  of the penetrating hole  24 , and the O-ring  35  held by the recessed portion  31   d  contacts with the sealing portion  27   c.  For the housing  31 , a compact formed by injection molding from the synthetic resin such as poly-acetal may be used. 
         [0059]    O-ring  35  is pressed in radial direction between the recessed portion  31   d  of the housing  31  and the sealing portion  27   c  of the valve holder  16  and seals the gap between the two by restoring force. 
         [0060]    The valve structure  32  is equipped with a stem rubber  36  having a flat ring shape held by the holding step  31   b  of the housing  31 , a stem  37  having a cylindrical shape which is to be inserted in the stem rubber, and a spring which always forces the stem  37  upward. The stem rubber  36  having a ring shaped in which the stem  37  is inserted in the bore portion, closes the housing  31  by provided on the holding step portion  31   b  of the housing  31 . A stem communicating hole  37   b  is formed on the lateral face of the stem  37 , which communicates with a stem inside oath  37   a  formed in the center of the stem  37 . When the stem  37  is inserted in the stem rubber  36 , the bore portion of the stem rubber  36  closes the stem communicating hole  37   b.  Therefore, the housing  31  is always covered by the stem rubber  36 . And by lowering the stem  37  against the stem rubber  36 , the gap is formed between the stem  37  and the stem rubber  36  and the stem communicating hole  37   b  is opened, As a result, the inside of the housing  31  and the stem inside path  37   a  is communicated. However, the valve structure  32  is not limited to above, as long as it closes the housing  31  of content path, and opens the housing  3  of content path by o e kind of operation. The spring  38  is provided between the bottom portion of housing and the lower end of the stem  37 . 
         [0061]    The cap  33  of  FIG. 1  fixes the stem rubber  36 , the stem  37 , and the spring  38  in the housing  31 . The cap  33  covers the top of the housing  31  and the lateral face  33   b  is clinched to the projecting portion  31   c  of the housing. 31 . Therefore, the stem  37  is forced upward by the spring  38  where the stem communicating hole  37   b  is sealed by the stem rubber  36 , and it is easy to handle the aerosol valve  17  as a whole when assembling. The lower end  33   a  of the cap  33  is extended straight in lowering direction. When the aerosol valve  17  is inserted in the penetrating hole  24 , the lower end  33   a  of the cap  33  is inserted in the annual channel portion  28 . The cap is formed with metal such as aluminum. 
         [0062]    The O-ring  18  of the valve holder  16  is a sealing member having a cross sectional view of circle before the valve assembly  12  is fixed to the container body  11  and before it is plastically deformed. The O-ring  18  is pressed in radial direction between the recessed portion  21   a  of the valve holder  16  and the neck portion  11   c  of the container body, and seals its space by the restoring force. Especially the clinching claws which force the neck. portion  11   c  of the container body  11  inside from the outside controls the press force of the sealing part, of the O-ring  18 . The O-ring  18  is made of elastic material such as nitrile rubber (NBR), butyl rubber (IIR), fluoro rubber, silicone rubber and etc. The O-ring  35  of the valve structure  32  also is essentially made of same material as the O-ring  18  of the valve holder  21 . 
         [0063]    Back to  FIG. 1 , the cover cap  19  is composed of an upper base  19   a  which covers the top of the container body, valve holder  16  and the aerosol valve  17 , an upper tube portion  19   b  which covers the periphery of the valve holder  16  and the lid portion  23 , and a lower tube portion  19   c  which covers the flange portion  22  of the valve holder  16  and which fixes the valve holder  16  and the aerosol valve  17  to the container body  11 . On the upper base portion  19   a,  a hole  20   a  which passes the stem  37  of the aerosol valve  16 , and a recessed portion  20   b  which presses the cap of the aerosol valve are formed. The cross sectional shape of the upper tube portion  19   b  is a circle in which a part is been deleted like the lid portion  23  of the valve holder  16  (see  FIG. 1   b ). The lower tube portion  19   c  is a fixing portion which sandwiches the flange portion  22  of the valve holder  16  and the bead portion  11   d  of the container body  11 . This lower tube portion  19   c  has a cylindrical shape before assembled, and is formed by plastic deforming the lower end  19   d  of the lower tube portion  19   c  which is to clinch the lower end  19   d  inside to the bead portion lid of the container body  11  with clinching claw (plastic deforming portion). 
         [0064]    The cover cap  19  is made of metal such as aluminum, tin plate and etc. 
         [0065]    The inner container  13  is equipped with a pouch  41  and a joint member  42  having a cylindrical shape which is welded or adhered to the opening of the pouch  41 . 
         [0066]    The pouch  41  is formed by welding or adhering plural of sheets. As for the sheet, a synthetic resin sheet such as polyethylene, polyethylene-terephthalate, nylon, eval, a vapor deposited resin sheet in which a silica or alumina is vapor deposited to the above synthetic resin, and a laminated sheets in which a metal foil such as an aluminum foil is laminated to the synthetic resin sheet, can be used. 
         [0067]    The joint member  42  is composed of a pouch fixing portion  42   a  adhered to the opening of the pouch  41 , and a valve joint portion  42   b  which couples with the joint portion  31   a  of the aerosol valve  17 . The valve joint portion  42   b  is engaged to the engaging projection  30   a  of the valve holder, however it may be engaged to the joint portion  31   a  of the aerosol valve  17 , On the lower end of the pouch fixing portion  42   a  of the joint member  42 , a tube  42   c  which is inserted in the pouch  41 , is provided. However, the tube  42   c  may not be provided. For the joint member  42 , an injection molding piece may be used. 
         [0068]    In this embodiment, the pouch  41  is used. However, a collapsible inner bag made of synthetic resin such as polyethylene, eval, or etc. for double aerosol container may be used. In that case, joint member may also be used to couple the inner bag and the container body, but the inner bag may be directly fitted to the joint portion of the housing of the aerosol valve. 
         [0069]    The discharge container  10  is manufactured by next steps. The valve assembly  12  in which the inner container  13  is fitted is held above the bead portion  11   d  of the container body  11  (see  FIG. 3   a ). Then, the propellant is charged in the arrow direction, through the space between the lower end  19   d  of the cover cap  19  and the bead portion lid of the container body  11 , and the space between the valve holder  16  and the bead portion lid (under cup charging). Simultaneously, the valve assembly  12  is lowered and have the O-ring  18  in contact with the neck portion  11   c  (cylindrical portion) of the container body  11 . And the lower end  19   d  of the lower tube portion  19   c  of the cover cap  19  is plastically deformed against the neck portion  11   c  of the container body  11  to be fixed with the bead portion  11   d  by the clinching claw  20 . At this moment, the neck portion  11   c  lower than the bead portion  11   d  is pressed inside by the tip of the clinching claw  20  and the pressing force of the O-ring  18  is controlled. In other word, the tip of the clinching claw  20  and the O-ring  18  is provided at same height while clinching. For the content, it may be charged into the inner container  13  before assembling the valve assembly, and it may be charged into the inner container  13  after the charging of the propellant and assembling of the valve assembly  12  to the container body by opening the stem  37 . 
         [0070]    In the above manufactured discharge container  10 , the deformation amount of the O-ring  18  may be controlled in 0.1 millimeter order by deforming the cylindrical portion (neck portion  11   c ) in micro order, when fixing the cover cap  19 . Therefore, the durability and accuracy of the sealing function is high. Further, although the dimension of the formed item of the container body  11  and the valve holder  16  of the valve assembly has margin of error, or that the inner surface of the container body  11  has wrinkles formed on the necking processing, the sealing function can be controlled at the last stage, therefore the manufacturing method of the discharge container  10  can be operated easy and will have high productivity. Further, because the fixing portion (lower tube portion  19   c ) of the cover cap  19  and the sealing structure (O-ring  18 ) are independent with each other, the cover cap  19  can be fixed firmly. Moreover, because the lower end  19   d  of the lower tube portion  19   c  of the cover cap  19  is deformed toward the neck portion  11   c,  the plastic deformation can be secured. 
         [0071]    On the discharge container  45  of  FIG. 4 , an annular hollow portion  46  pitted inside is formed on the neck portion  11   c  of the container body  11 , for pressing the O-ring  18  held in the recessed portion  21   a  of the plug portion  21  of the valve holder  16 . The outer diameter of the lower late a surface  47   a  of the plug portion  21  of the valve holder  16  (part lower than the recessed portion  21   a ) is some what smaller than the lateral surface of the plug portion  21  to support the annual hollow portion  46 . That is, because the outer diameter of the lateral surface of the plug portion  21  of the valve holder  16  (part higher than the recessed portion  21   a ) is some what larger than the lower lateral surface  47   a  (part lower than the recessed portion  21   a ), it can avoid the O-ring  18  to escape upward and to twist when the valve holder  16  is inserted into the container body  11 . The rest of the composition is substantially same as the discharge container of  FIG. 10 . 
         [0072]    By providing the annular hollow portion  46 , the sealing function can be enhanced by having the O-ring  18  to be pressed not just from left and right but also from up and down. The annular hollow portion  46  can be formed after the assembling of the discharge container  10  worked from outside or at the manufacturing of the container body  11 . 
         [0073]    Further, the outer diameter of the lower lateral surface  47   a  of the plug portion  21  may be designed to be same or slightly larger than the inner diameter of the annular hollow portion  46  of the container body  11 , and the lateral surface and the lower lateral surface  47   a  of the plug portion  21  may be provided with a channel extending vertically to create the passage for the propellant to be charged. 
         [0074]    The discharge container  50  of  FIG. 5   a  is equipped with a container body  51  made of metal, a valve assembly  52  fixed to the container body, and an inner container  13  inserted into the container body  51 . The container body  51  is substantially same as the container body  11  of  FIG. 1 , except that a barrel portion  51   a,  a shoulder portion  51   b,  a neck portion  51   c,  and a bead portion  51   d  have small diameter than the container body  11 . The inner container  13  is substantially same as the inner container  13  of  FIG. 1 . The discharge product is produced by storing the content in the inner container  13  of the discharge container  50 , and by charging the propellant in the space between the container body  51  and the inner container  13 . The discharge container  50  is a container which discharges one content. 
         [0075]    As for the valve assembly  52 , the valve structure  32  is directly fixed to the penetrating hole. That is, the penetrating hole of the valve holder works as the passage of the content. 
         [0076]    The valve assembly  52  is equipped with a valve holder  56  inserting into the opening of the container body  51 , a valve structure  32  fixed to the valve holder, an O-ring  18  provided on the outer surface of the valve holder  56 , and a cover cap  59  covering those and fixed to the outside of the bead portion of the container body. The O-ring  18  and the valve structure  32  are substantially same as those of  FIG. 1 . 
         [0077]    The valve holder  56  has a plug portion  21  having column shape, a flange portion  22 , and a lid portion  23  having column shape and is substantially same as the valve holder  16  of  FIG. 1 , except for that the valve holder  56  has one penetrating hole  56   a  and has a columned shape without the notch portion. 
         [0078]    The penetrating hole  56   a  is formed with a spring support portion  57   a  supporting the spring  38  of the valve structure  32 , and a holding step  57   b  formed on top of the inner surface holding the stem rubber  36  of the valve structure. 
         [0079]    The cover cap  59  has a upper base  59   a  which is formed in accordance with the shape of the valve holder  56  and which has a hole  60   a  on the center for the stem to be inserted, an upper tube portion  59   b  having a cylindrical shape, and a lower tube portion  59   c  formed on below the upper tube portion. 
         [0080]    This discharge container  50  is also manufactured like the discharge container  10  of  FIG. 1 . That is, after the charging of the propellant, the valve assembly  52  is lowered to have the O-ring  18  to be in contact with the neck portion  51   c  (cylindrical portion) of the container body  51 , and the cover cap  59  is fixed to the container body  51  by plastically deforming the lower end  59   d  of the lower tube portion  59   c  of the cover cap  59  toward the neck portion  51   c  of the container body  51  with the clinching claw. Therefore, the pressing rate of the O-ring  18  can be controlled by pressing the neck portion  51   c  of the container body  51  inwardly with the tip of the clinching claw. Resultantly, the durability and the accuracy of the sealing function are high. 
         [0081]    The discharge container  60  of  FIG. 5   b  is equipped with a container body  51  made of metal, and the valve assembly  52  fixed to the container body. The discharge container  60  does not have the inner container and it is provided with the dipping tube  61  fixed to the lower end of the valve holder  56  of the valve assembly  52 , except that the rest of the composition is substantially same as the discharge container  50  of  FIG. 5   a.    
         [0082]    The discharge product is produced by charging both the content and the propellant into the container body  51  of the discharge container  60 . 
         [0083]    The discharge container  70  of  FIG. 6   b  is equipped with the container body  51  made of metal, a valve assembly  72  fixed to the container body, and the inner container  73  inserted into the container body  51 . The container body  51  is substantially same as the container body  51  of  FIG. 5 . 
         [0084]    In this discharge container  70 , the inner bag having collapsible behavior made of synthetic resin is used as the inner container  73  and the shape of the valve holder of the valve assembly  72  is different from the valve holder of discharge container  50  of  FIG. 5   a , other than that, the discharge container  70  is substantially same as the discharge container  50  of  FIG. 5   a.    
         [0085]    The valve assembly  72  is equipped with a valve holder  75  inserted into the opening of the container body  51 , a valve structure  32  fixed to the valve holder, an O-ring  18  provided on the periphery of the valve holder  75 , and a cover cap covering them and fixed to the periphery of the opening of the container body. The O-ring  18  and the valve structure  32  are substantially same as the one of  FIG. 5 . 
         [0086]    In the valve holder  75 , the flange portion doubles as the lid portion. For the other compositions, it is substantially same as the valve holder  56  of  FIG. 5 , where it has cylindrical column shape without the notch portion, and has plug portion  21  and flange portion  22 . 
         [0087]    The cover cap  74  has a tube portion  74   a  which is formed in accordance with the shape of the valve holder in which the upper tube portion and the lower tube portion is united. The other configuration is substantially same as the valve holder  56  of  FIG. 5   
         [0088]    This discharge container  70  is also manufactured like the discharge container  50  of  FIG. 5 . That is, the valve assembly  72  fitted with the inner container  73  is held above of the bead portion  51   d  of the container body  51  (see  FIG. 6   a ). Then, the propellant is charged in arrow direction from a space between the lower end  74   d  of the cover cap  74  and the container body  51  to a space between the container body  51  and the valve holder  75 . Simultaneously, the valve assembly  72  is lowered to have the O-ring  18  to be in contact with the neck portion (cylindrical portion) of the container body. Finally, the lower end  74   d  of the cover cap  74  is plastically deformed toward the neck portion  11   c  of the container body  11  with the clinching claw and have the cover cap  74  fixed to the bead portion  51   d.  During this clinching process, the press force of the O-ring  18  is controlled by pressing the neck portion  51   c  of the container body  51  inside with the tip of the clinching claw  20 . Therefore, the durability and the accuracy of the sealing function are high. 
         [0089]    The discharge container  80  of  FIG. 7  comprises a joint member  82  which efficiently guides the content in the pouch  41  to the valve assembly  12 . That is, the joint member  82  of the inner container  81  has a guiding portion  83  which is to be inserted in the pouch  41 . The container body  11  made of metal, the valve assembly  12 , and the pouch  41  are substantially same as those of discharge container  10  of  FIG. 1 . 
         [0090]    The joint member  82 , like shown in  FIG. 8 , has a pouch fixing portion  42   a,  a valve connecting portion  42   b,  and the guiding portion  83  which extends downward from the lower end of the pouch fixing portion  42   a.  The pouch fixing portion  42   a  and the valve connecting portion  42   b  are substantially same as those of discharge container  10  of  FIG. 1 . 
         [0091]    The guiding portion  83  comprises a main body  84  extending vertically, a communicating portion  85  which is provided on top of the main body  84  and which communicates the surface of the main body  84  with the center hole of the valve connecting portion  42   b,  a projecting portion  86  which extends vertically and which is projected from the surface of the main body, and a bottom portion  87  having a circular plate shape formed on the lower end of the main body  84 . 
         [0092]    The main body  84  is flat plate extending vertically. However, it may be a pole (cylindrical column) like shown in  FIG. 8   e.    
         [0093]    The communicating portion  85  is a hole formed vertically from the top of the main body  84  and which communicates with the center hole of the valve fixing portion  42   a.    
         [0094]    The projecting portion  86  is composed of plural of main projections  91  formed concentrically and formed apart in vertical direction, and plural of sub projections  92  which is provided between the adjacent main projections  91  and which does not intersect with the main projections  91 . The main projection  91  is projected perpendicularity against the surface of the pouch  41 , and the sub projection  92  is projected parallel with the surface of the pouch  41 . 
         [0095]    The main projection  91 , like shown in  FIG. 8   a ,  8   h ,  8   c , is composed of plural of first main projections  91   a  formed concentrically and formed on the front surface of the main body  84  (left side of the  FIG. 8   b ), and the plural of second main projections  91   b  formed concentrically and formed on the rear surface of the main body  84  (right side of  FIG. 8   b ). In this embodiment, the first main projections  91   a  and the second main projections  91   b  are projected in opposite directions on the same position so as to be like a pair. First main projections  91   a  and second main projections  91   b  each have four projections. However, the numbers are not limited as long as it is more than two. It is preferable to have 2 to 8. 
         [0096]    An axis line cross sectional view of the main projection  91  is half moon shape. The center of the main projection has the largest protruding amount from the main body  84  and the protruding amount gently decreases toward the upper end and the lower end. Further, a horizontal. line cross sectional view of the main projection  91 , like shown in  FIG. 8   c , is a mountain shape, where the top is curved or flat and the slope is slightly curved so as to project outwardly or flat. 
         [0097]    The space between the adjacent first main projections  91   a  or the space between the adjacent second main projection  91   b  is a plane face portion  93  which is a front surface or a rear surface of the main body  84 . 
         [0098]    Further, on the foot of the main projection  91  (first main projection  91   a  and second main projection), there is channel portion  94  formed parallel with the main projections  91  respectively (see  FIG. 8   a ,  8   c ). On the other hand, if the main body  84  has a cylindrical column shape like shown in  FIG. 8   e , the plane face portion  93  will be curved surface, and the straight passage will be formed between the foot of the plane face portion which is curved and the channel portion  94 . 
         [0099]    The sub projection  92  has plural of first sub projections  92   a  provided on one line on the right lateral face of the main body  84  (right side of  FIG. 8   a ) and plural of second sub projections  92   b  provided on one line on the left lateral face of the main body  84  (left side of  FIG. 8   b ). In this embodiment, each of the first sub projection  92   a  and the second sub projection  92   b  is provided not just between the adjacent main projections, but also between the main projection  92   a  and the pouch fixing portion  42   a  and between the main projection  91  and the bottom portion  87 . The height of the first sub projection  92   a  and the second sub projection  92   b  are arranged in same pattern forming a pair. The position of top and bottom of the sub projection  92  and position of the bottom and top of the main projection  91  overlaps in side view. 
         [0100]    An axis line cross sectional view of the sub projection  92  is half moon shape (see,  FIG. 8   a ). That is the projecting amount is maximum at the center of the sub projection  92  and the projecting amount decreases toward the top and bottom. 
         [0101]    Moreover, on the first sub projection  92   a  and the second sub projection  92   b,  a protrusion  96  is formed perpendicular to the surface of the pouch (same direction as the main projection  91 ) (see  FIG. 8   b ,  8   c ). The protrusion  96  is provided on the front and rear surface of the first sub projection  92   a  and the second sub projection  92   b.  The protrusion  96  has a half moon shape in axis line sectional view, in which the protruding amount increases toward the middle from the outside forming a inclined line or a curved line. On the other hand, the shape of the lateral face including the first sub projection  92   a  and two protrusions  96  formed on its side can he designed to be half rugby ball shape and the shape of the other lateral face including the second sub projection  92   b  and the two protrusions  96  formed on its side can be designed to be half rugby ball shape, and can be designed to be approximately rugby ball shape as a whole. 
         [0102]    The largest protruding part of the main projection  91  and the sub projection  92  are provided to be apart vertically. The plane face portion  93  is provided between the first sub projection  92   a  and the second sub projection  92   b.  The channel portion  94  of the main projection  91  has an opening between the vertically adjacent sub projections  92 . And the vertically adjacent sub projections  92  and the plane face portion  93  are communicated with channel portion  94 . Although the largest protruding part of the main projection  91  and the sub projection  92  are provided vertically apart, the upper end and the lower end of the main projection  91  and the sub projection  92  is overlapped in vertical direction. Therefore, the passages formed of main projection and the sub projection can be connected easily. 
         [0103]    The bottom portion  87  having a circular disk shape is formed to be perpendicular to the surface of the pouch  41 . To have the bottom portion in circular disk shape, the pouch  41  won&#39;t be ruptured when the pouch  41  shrink and contact with the bottom portion  87 . It is designed to have the bottom portion  87  not to come in contact with the bottom portion of the pouch  41 . In other word, there is a space between bottom portion  87  and the bottom portion of the pouch  41 , therefore, when pouch  41  shrinks and if the pouch  41  shrinks in vertical direction, the bottom portion  87  will not press the pouch  41  and tear the pouch  41 . Further, because the pouch  87  has three-dimensional conformation, the passage between the bottom portion  87  and the pouch is formed. Further, it is preferable that the both side ends of the bottom portion  87  perpendicular to the surface of the pouch protrudes outside compare to the tip of the first main projection  91   a  and the second main projection. 
         [0104]    Next, the process of content discharging from this discharge product is described, especially the passage formed by the joint member is described. 
         [0105]    Back to  FIG. 7 , the valve structure of the valve assembly  12  is opened. by lowering the stem  37  of the discharge container  80 , and the atmosphere communicates with the inside of the pouch  41 . Therefore, the pouch  41  is been pressed by the propellant charged in the space between the container body  11  and the pouch  41 , and the content which is guided to the center hole of the valve fixing portion  42   b  by the guiding portion  83 , is pushed out from the pouch  41  and discharged outside through the stem  37 . 
         [0106]    The pouch  41  will contract and the surface of the pouch will be in contact with each other, however the passage will be maintained by the action of the guiding portion  83 . 
         [0107]    That is, along with the discharge of the content, an upper part of the surface of the pouch  41  in vicinity of the communicating portion  85  will be pressed inside and come close with the opposite surface of the pouch  41 , and this part will come in contact with the protrusion portion  86 . And by further discharging the content, the pouch  41  deforms in perpendicular direction pressing the main projection  91  and the protrusion  96  (see  FIG. 9   b ), and at the same time, the surface of the outside edge of the pouch  41  (edge which is apart from the guiding portion contact with each other, and deform horizontally toward the center axis of the pouch  41  in the contact state (see  FIG. 9   a ,  9   c ). The hatch line of the net in  FIG. 9   a  shows the part where the opposing surfaces are in contact with each other. 
         [0108]    In the deformation of the pouch  41  in perpendicular direction, the main projection  91  and the protrusion  96  projecting in the perpendicular direction against the surface of the pouch behaves as the rib against the contracting surface of the pouch  41 , like shown in  FIG. 9   b.  And forms a space between the guiding port on  83  and the pouch  41  (space formed on the front and back of  FIG. 9   b ). That is to say, the space is formed between the plane face portion  93  which is surrounded by the above and below main projections  91  and right and left protrusions  96 , and the pouch  41 , and formed between the hemline of the main projections  91  (channel portion  94 ) and the pouch  41 . And this space forms the passage P 1  of vertical direction on the main body  84  which connects the inside of the pouch  41  with the communication portion  85 . Moreover, because the adjacent, up and down passages P 1  are formed on same line, the contents are carried in straight line on the plane face portion  93 , therefore it is efficient. Further, even if the pouch  41  is shrunk or the pouch  41  is elongated and the space disappeared by the surface of the pouch  41  cohere with the main projection  91 , the passage P 1  can be secured by the channel portion  94 . 
         [0109]    On the other hand, as shown in  FIGS. 9   a ,  9   c , in the deformation of the pouch  41  in the horizontal direction, the cohesion of the front and back surface of the pouch  41  between the adjacent sub projections  92  is prevented by the sub projections  92  projecting in parallel with the pouch surface and protrusions  96  projecting perpendicularly against the surface of the pouch  41 . Further, it prevents the part of the pouch  41  in which the front and back is cohered, to deforms toward the axis, and prevents the space formed between the sub projection  92  to be shut. Therefore, the space between the adjacent sub projections  92  is secured. This space secured between the adjacent sub projections  92  forms the sub passage P 2  which communicates the inside of the pouch with the passage P 1 . In this embodiment, the sub passages P 2  are formed on left, right, top, and bottom, therefore, the contents are applied from the upper side of the pouch  41  (upper side of the sub passage P 2 ). And, even if the pouch  41  is cohered with the lower part of the guiding portion  83  while deforming, the passage won&#39;t be blocked, and the contents can be discharged till the end. 
         [0110]    Further, because the axis line cross sectional view of the main projection  91  is half moon shape, it ease the formation of the space between the plane face portion  93  and the pouch  41 . Moreover, because the cross sectional shape on the horizontal direction of the main projection  91  is mountain shape where the tip is curved, the pouch  41  will not be torn even if the pouch  41  comes in contact with the main projection  91  by the press force of the propellant. 
         [0111]    Because, the protrusion  96  also has axis line cross sectional view is half moon shape, in which the projection amount increases from the outer edge to the inside, the pouch  41  will not be torn even if the pouch  41  comes in contact with the protrusion  96  by the press force of the propellant. 
         [0112]    One embodiment of the guiding portion  83  is shown in the joint member  82  of  FIG. 7 . However, the guiding portion is preferable as long as it is three dimensional structure having two main projections formed apart in vertical direction and formed on one straight line. 
         [0113]    This joint member  82  may be used to other discharge containers which are not present invention, as long as the discharge containers are a double aerosol container which is equipped with a pouch. For example, an aerosol container having a pressure resistant container made of synthetic resin, a pouch housed in the container, and a valve assembly having valve structure which communicates the outside with the inside of the pouch, where the propellant is charged between the container and the pouch. This joint member  82  can efficiently guide the content in the pouch to outside. 
         [0114]    Due to forming the sub projection between two main projections and without crossing with the main projection like the joint member  82  of  FIG. 7 , a bumpy surface having three dimensional structures can be formed on the surface of the guiding part. And because the surface area of the passage member (guiding portion) is greatly increased, the formation of the space between the passage member and the pouch will be facilitated. Especially, by having the sub projection between the adjacent main projections where the pouch most likely contacts, the formation of the space between the flat surface (surface of the main body of the guiding portion) which is formed between the adjacent main projections and the pouch will further be facilitated. However, the sub projection may be omitted. 
         [0115]    Like the joint member  82  of  FIG. 7 , by forming the channel on the hemline of the main projection parallel to the main projection, the passage parallel to the main projection can be secured. However, the channel portion may be omitted. 
         [0116]    Like the joint member  82  of  FIG. 7 , by having the main projection projected perpendicular to the surface of the pouch, and the sub projection projected parallel to the surface of the pouch, the contraction of the pouch can be controlled. However, as long as the main projection and the sub projection which forms the three dimensional structure between the guiding portion and the pouch, the projecting direction of the main projection and the sub projection is not limited. 
         [0117]    Like the joint member  82  of  FIG. 7  having the protrusion  96  projected perpendicular to the surface of the pouch on the sub projection, the surface area of the passage member will be further increased. Especially the protrusion is formed away in vertical direction from the main projection, it prevents surface of the pouch to contract, secure the passage formed in vertical direction, and secure the sub passage guiding the space between the sub projections to the hemline of the main projection. 
         [0118]    The joint members of  FIGS. 10   a  to  10   c  are the alternatives of the joint member  82  of  FIG. 7 . 
         [0119]    In the joint member  82   a  of  FIG. 10   a , the flat surface  93  of the joint member  82  of  FIG. 7  is replaced by a penetrating hole  98 . By having penetrating hole  98 , the material can be reduced. The other configuration is substantially same as the joint member  82  of  FIG. 7 , and has the pouch fixing portion  42   a,  the valve connecting portion  42   b,  and the guiding portion  83 . 
         [0120]    In the joint member  82   b  of  FIG. 10   b , the sub projection  92   a,    92   h  is projected to form an isosceles trapezoid from the main body  84 , both sub projections are longer than the sub projections of joint member  82  of  FIG. 7 , and the distance between the adjacent sub projections is smaller than the joint member  82  of  FIG. 7 . It eases the formation of the sub passage P 2 . The other configuration is substantially same as the joint member  82  of  FIG. 7 , and has the pouch fixing portion  42   a,  the valve connecting portion  42   b,  and the guiding portion  83 . 
         [0121]    In the joint member  82   c  of  FIG. 10   c , the projection amount of the main projection  93   a,    93   b  is larger than the main projection  91   a,    91   b  of the joint member  82  of  FIG. 7 . It creates larger bump on the main body  84 , and further secures the formation of the passage P 1 . 
         [0122]    The discharge container  95  of  FIG. 11   a  has a penetrating hole  97  on the upper base  96   a  of the cover cap  96  for ejecting the propellant intruded between the cover cap  96  and the valve holder  16 . Generally the quality test or inspection of the discharge container in which the propellant is charged, is conducted by having the assembled discharge container to be dipped in the water (hot water) and check the e of the bubble. However, in this discharge container, there is a chance that the propellant may intrude between the valve holder  16  and the cover cap  96  during the under cup charging of the propellant. This penetrating hole  97  ejects such a propellant before the test. As a result, the quality test can be conducted with accuracy. 
         [0123]    Further, in this discharge container  95 , a dented portions  20   b  are formed on the upper base  96   a  of the cover cap  96  other than the recessed portion  20   b  pressing the cap of the aerosol valve, for holding or pressing the valve holder  16  and the aerosol valve  17 . This dented portion  20   b  further prevents the valve holder  16  to move against the external force and inner pressure. 
         [0124]    Other configuration is substantially same as the discharge container  10  of  FIG. 1 . Further, guiding channel  99  to guide the propellant intruded between cover cap  96  and the valve holder  16  to the penetrating hole  97 , may be provided on the upper surface of the valve holder  16 , like the discharge container of  FIG. 11   b , and  FIG. 11   c.
