Description:
FIELD OF INVENTION 
       [0001]    The present invention relates to a two-liquid discharge container. Specifically, the present invention relates to a two-liquid discharge container which is to independently store two liquids in one container, and which can easily discharge in mixed state or which can discharge two liquids independently at same time and mix afterwards. 
       DESCRIPTION OF BACKGROUND ART 
       [0002]    The patent document 1 discloses a two-liquid discharge container equipped with an inner bag made of synthetic resin to be inserted in the container body made of metal, which can store two different concentrates. This inner bag has a constriction portion in the middle, and the interior of the inner bag is vertically divided into two storages by inserting the plug in the constriction portion. 
         [0003]    In this two-liquid discharge container, concentrates are charged in two storages respectively, and the propellant (pressurized gas) is charged between the container body and the inner bag. And the concentrates are to be discharged by the pressure of the propellant. However, because only the concentrates in the inner bag is discharged, it was not possible to discharge the concentrate in foam or in mist. 
         [0004]    Further, the inner bag is made of thin and soft synthetic resin where it is to be clashed by the propellant and is filled with the concentrate in liquid-tight condition, therefore, there is a problem, when the two concentrates are stored for extended period of time, that the content in one storage move to other storage by infiltrating the inner bag and reacts with other concentrate. 
         [0005]    In FIG. 14 of patent document 2, plural-liquid discharging aerosol container having a container body made of synthetic resin where the pouch filled with concentrate is stored and where the liquefied gas is stored in same space is disclosed. In this aerosol container, plural contents are stored in one container body, and the discharging state of the content can be changed by liquefied gas. However, because the pouch is soaked in the content including the liquefied gas, there is a problem that the contents reacts with each other and be degraded, unless the means to prevent the penetration of the content through the bonding portion of the pouch is provided. 
         [0006]    In patent document 3, a two-liquid discharge system having a first aerosol container with the dispensing member (push button), and a second aerosol container without the dispensing member, where the concentrate and the liquefied gas are stored in each container and where the second aerosol container is coupled to the bottom of the first aerosol container when in use, is disclosed. In this system, the separate storage of two concentrates is secured and the manufacturing is easy. However, two aerosol containers are necessary, and the liquefied gas may leak from the coupling portion. 
         [0007]    In FIG. 3a of patent document 1, an aerosol valve in which two liquids are to be mixed in the housing and discharged outside is disclosed. Further, in FIG. 3b of patent document 1, an aerosol valve having two stem rubbers positioned one above another, where two liquids are discharged outside independently through two passage arranged in parallel in the stem, is disclosed. Moreover, in FIG. 3 and FIG. 5 of patent document 2, a valve assembly having two passages concentrically formed in the stem for two liquids to be discharged, is disclosed.

       DESCRIPTION OF THE INVENTION 
     Problems to be Solved 
       [0010]    The present invention is directed to provide a two-liquid discharge container which can stably store two or more liquids, which can be easily mix the stored liquids, which can discharge the liquid in varied state such as in foam, mist, and etc., and which can prevent the reaction of the liquids when kept for long period of time. 
       Means of Solving the Problem 
       [0011]    The present invention of a two-liquid discharge container is characterized in that it comprises a container body made of non-metal material, a partition wall member vertically dividing an interior of the container body into plural of storages, and a valve having a discharge passage communicating storages with outside, where contents are charged in each storage, where at least one of the content contains a liquefied gas, and where a gas lies between a liquid charged in the lower storage directly below the partition wall member and the partition wall member. Especially, it is preferable that the container body is made of synthetic resin or glass. 
         [0012]    In the two-liquid discharge container of the present invention, it is preferable that the container body has a constriction portion between the storages, in which the constriction portion is radially contracted, and where the storages are partitioned by inserting the partition wall member in the constriction portion. 
         [0013]    In the two-liquid discharge container, it is preferable that the discharge passage is composed of a first discharge passage communicating the upper storage with outside, and a second discharge passage communicating the lower storage with outside. 
         [0014]    Especially, it is preferable that a pouch is housed in at least one storage, and where a concentrate of the content is charged in the pouch and a propellant of the content is charged in the storage outside of the pouch. 
         [0015]    In the two-liquid discharge container of the present invention, it is preferable that the first discharge passage and/or the second discharge passage communicates with a gas phase in the respective storages in an stand-up condition, and the first discharge passage and/or the second discharge passage communicates with a liquid phase in the respective storages in an inverted condition. 
         [0016]    On the other hand, it may be that the first discharge passage and/or the second discharge passage communicates with a liquid phase in the respective storages in a stand-up condition. 
         [0017]    Especially, it is preferable that it comprises a first tube passage communicating the upper storage with the valve and a second tube passage communicating the lower storage with the valve, and where the first tube passage and the second tube passage are arranged concentrically. 
         [0018]    In the two-liquid discharge container of the present invention, it is preferable that the partition wall member is a strechable saclike member, and where the partition wall member divides the interior of the container body when filled with a gas and the storages are communicated when the gas is released. 
       Effect of the Invention 
       [0019]    In the two-liquid discharge container of the present invention, because it is equipped with a container body made of non-metal material, it can stably store contents which react with the metal. Further, because the interior of the container body is vertically partitioned by the partition wall member and the gas lies between the liquid charged in the lower storage directly below the partition wall member and the partition wall member, the liquids (concentrates) are not adjacently stored with the thin synthetic resin coating or such in between. Therefore, the liquid will not infiltrates the synthetic resin coating and liquids (concentrates) will not be degraded by reacting with each other. As a result, the stability of the product is high. Especially, when the container body made of synthetic resin or glass is used, it can stably store the contents and the manufacturing is easy. 
         [0020]    Further, because at least one of the content contains a liquefied gas, the liquefied gas mixed in the concentration vaporizes and expands when in discharging. Therefore, the liquid concentration such as liquid, cream, gel, etc. can be discharged in preferable condition such as foam, sparkling cream, sparkling gel, cream or gel with the air bubble dispersed in side, mist, etc. For example, in the case of two-liquid type hair dye, by controlling the hardness of the foam or sparking cream, it can easily mix two concentrates, or it can easily spread the concentrate to the hair, etc., or it can prevent the drip off of the concentrates from the hair, etc. 
         [0021]    In the case where the container body has a constriction portion between the storages, the constriction portion is radially contracted, and where the storages are partitioned by inserting the partition wall member in the constriction portion, the partition wall member can made to be small, and the inserting of the partition wall member into the container body will be easy. Especially, it is preferable to have the inner diameter of the constriction portion to be substantially same as the inner diameter of the opening of the container body, or smaller than the inner diameter of the opening of the container body. 
         [0022]    In the case where the discharge passage is composed of a first discharge passage communicating the upper storage with outside, and a second discharge passage communicating the lower storage with outside, the contents can be independently supplied from respective storage to outside through the tip of the valve, therefore, contents will not be mixed in the passage (inside the aerosol container). Therefore, it can be used repeatedly with the time in between. 
         [0023]    In the case where a pouch is housed in the storage, and where a concentrate of the content is charged in the pouch, the concentrate can be stably stored without directly contacting the container body made of synthetic resin, even if the concentrate is a agent which converts the container body made of synthetic resin (polyethylene terephthalate), such as a first agent (alkaline agent) of the two-liquid type hair dye. Therefore, two liquids can be stored in stable condition. Further, because the propellant of the content is charged in the storage outside of the pouch, it can prevent the other content to penetrate into the pouch. 
         [0024]    In the case where the first discharge passage and/or the second discharge passage communicates with a gas phase in the respective storages in a stand-up condition, and the first discharge passage and/or the second discharge passage communicates with a liquid phase in the respective storages in an inverted condition, because the discharge passage will be filled with air in the stand-up condition, it can prevent the mixture of two liquids inside the discharge passage, even if the contents are agents which infiltrates the synthetic resin of poly-acetal, etc, such as two-liquid type hair dye and the partition wall member is made of synthetic resin. Therefore, it can store the contents more stably. And by inverting the container body when in use, the liquids in the storage moves to the upper side and the discharge passage communicates the liquid part (liquid phase) with the outside, and the contents can be discharged outside. Further, after the discharging, by storing the two-liquid discharge container in the stand-up condition, the discharge passage once again will be filled with the gas and the gas will isolates two liquids for the contents to be stored stably. 
         [0025]    The two-liquid discharge container may be structured to be used in the stand-up condition, where the first discharge passage and/or the second discharge passage communicate with a liquid phase in the respective storages in a stand-up condition. In this case, handling during the discharge operation, is easy, even if the container body is heavy. 
         [0026]    In the case of the two-liquid discharge container of the present invention, where a first tube passage communicating the upper storage with the valve and a second tube passage communicating the lower storage with the valve are comprised, and the first tube passage and the second tube passage are arranged concentrically, because the structure of the discharge passage in the container body will be simple, the handling of the discharge passage during the assembling will be easy. 
         [0027]    In the case of the two-liquid discharge container of the present invention, where the partition wall member is a strechable saclike member, and the partition wall member divides the interior of the container body when filled with a gas and the storages are communicated with each other when the gas is released, two liquids can be stably stored. And storages can be communicated by releasing the gas in the partition wall member. Therefore, each content in the storages can be mixed in the container body before discharging.

     EMBODIMENT FOR CARRYING OUT THE INVENTION 
       [0040]    A two-liquid discharge container  10  of  FIG. 1  is equipped with a container body  11  made of synthetic resin; a partition wall member  12  which divides the inside of the container body vertically; a valve assembly  13  which closes the top opening of the container body  11  and which opens and closes a pass between the inner space and the outside. The partition wall member  12  hermetically divides the inside space of the container body into an upper storage  14  and a lower storage  15 , and is equipped with a pipe  16  which communicates the valve assembly  13  with the lower storage  15 . In this embodiment, the pipe  16  is made of synthetic resin and integrally formed with a partition wall portion  20 . However, the pipe  16  and partition wall portion  20  may be made of metal. In the two-liquid discharge container  10 , the first content  17  including the liquid concentrate G 1  and the liquefied gas L 1  and the second content  18  including the liquid concentrate G 2  and the liquefied gas L 2  are stored in the upper storage  14  and the lower storage  15 , respectively. 
         [0041]    The container body  11  has a constriction portion  11   e  which is radially contracted and which is formed between the upper storage  14  and the lower storage  15 . Specifically, it is a pressure resisting container made of synthetic resin which comprises a barrel portion  11   a  of a tube shape having a bottom portion, a shoulder portion  11   b  of a tapered shape formed on top of the barrel portion, a neck portion  11   c  of a tube shape formed on top of the shoulder portion, and a flange  11   d  formed on top and outer periphery of the neck portion. The constriction portion  11   e  of an approximately tube shape is formed on the midway of the barrel portion  11   a . The container body  11  presents like gourd shape as a whole. Each of the inner surface of the neck portion  11   c  and the inner surface of the constriction portion  11   e  is smooth tube face. It may be little tapered. 
         [0042]    For the synthetic resin of the container body  11 , a material which will not be eroded by the stored contents is selected. The container body  11  is formed by biaxial stretching blow molding using a thermoplastic resin such as polyethylene terephthalate, polycyclohexane dimethylene terephthalate, polyarylate, nylon, etc, may be adopted. For example, heating a parison formed by injection molding, and forming in predetermined configuration by stretching or inflating the parison in axis direction in the die. The neck portion  11   c  and the flange  11   d  is common with the parison, it is not to be stretched, so it is made to be thick. The container body  11  may be provided with translucency and may be made from the synthetic resin having translucency. In this case, the remaining and the condition of the contents may be sighted. Further, to protect the contents from the ultraviolet, the inner surface or the outer surface of the container body  11  may be coated with carbon, alumina, silica, etc. 
         [0043]    The partition wall member  12  comprises a partition wall portion  20  of a column shape which engages with the inner surface of the constriction portion  11   e , and a pipe  16  extending upwardly from the middle of the partition wall portion  20 , where it has a corrosion resistance against the contents as a whole, and where it is made of synthetic resin. For enhancing the gas barrier properties and preventing the infiltration of the contents (liquid concentrate), a tube (see note  16   b  of  FIG. 2 ) or a circular disk made of metal such as stainless steel may be assembled. And a metal sheet or metal foil may be under-laid and metal may be vapor deposited according to the portions. On top and outer periphery of the partition wall portion  20 , an engage flange  20   a  which engages with the inner wall of the upper storage  14  is formed. A circular groove or channel is formed on the outer surface of the partition wall portion  20 , and the O-ring  20   b  is fixed to the circular groove. 
         [0044]    On bottom surface of the partition wall portion  20 , a depressed portion  20   c  of a conical shape or a truncated cone shape which narrows upwardly is formed. And a hole  16   a  of the pipe  16  is extended to the top surface of the partition wall portion  20 . In this embodiment the partition wall portion  20  and the pipe  16  are integrally formed, however, it may be formed separately. In that case, both are to be coupled hermetically. 
         [0045]    The valve assembly  13  is equipped with a valve holder  21  fixed to the opening of the container body  11 , a valve mechanism  22  housed in the middle of the valve holder  21 , and a mount cover  23  for fixing the valve holder  21  to the container body  11 . 
         [0046]    The valve holder  21  has an outer cylindrical portion (circular wall)  26  which is to be inserted and fitted in the neck portion  11   c  of the container body  11 ; a flange  27  which extends outwardly from the top of the outer cylindrical portion and which engages with the top of the neck portion  11   c ; an inner cylindrical portion  28  which holds the valve mechanism  22  and has a tube shape with a ceiling; and a coupling portion  29  which connects the bottom of the outer cylindrical portion  26  and the inner cylindrical portion  28 . The flange  27  of the valve holder  21  and the top of the neck portion  11   c  of the container body  11  are sealed with a gasket  25   a  of ring shape in between. The valve holder  21  is made of synthetic resin. The mount cover  23  which is covers the valve holder  21  is made of metal thin plate such as aluminum thin plate, etc. The bottom of the outer peripheral wall of the mount cover  23  is to be deformed to the under surface of the flange  11   d  of the neck portion of the container body for fixing. By using the valve holder  21  and the mount cover  23 , the neck portion  11   c  having large diameter may also be securely closed and sealed. 
         [0047]    The valve mechanism  22  is equipped with a housing  30  of a tube shape with a bottom; a stem  31  housed movably in vertical direction in the housing  30 , and a spring  32  which forces the stem upward. The stem  31  has an outer tube (large diameter tube) and an inner tube (small diameter tube) concentrically inserted in the outer tube with interval, in which the top of the inner tube is to be protruded from the top of the outer tube. The center hole of the small diameter tube is a first stem passage  31   a  which communicates with the upper storage  14  through the upper space of the housing  30 . The space between the large diameter tube and the small diameter tube is a second stem passage  31   b  which communicates with the lower storage  15  through the lower space of the housing  30  and the pipe  16 . In this embodiment, the second stem passage  31   b  surrounds the first stem passage  31   a . However, two stem passages may be arranged in parallel like in patent document 1. That is, in this embodiment, the discharge passage comprises two passages in which each passages independently communicates each storages with outside. 
         [0048]    The bottom of the first stem passage  31   a  of the stem communicates with the first stem hole extending in radial direction, and the bottom of the second stem passage  31   b  of the stem communicates with the second stem hole below the first stem hole. The first stem hole and the second stem hole are closed by the first stem rubber  34   a  and the second stem rubber  34   b , respectively, and both are freed when the stem  31  is lowered. The space between the first stem rubber  34   a  and the second stem rubber  34   b  is communicated with the upper storage  14  through the upper communicating hole  35   a  formed on the lateral wall of the housing  30 . The space below the second stem rubber  34   b  is communicated with the lower storage  15  through the bottom hole  35   b  of the housing  30  and the pipe  16  of the partition wall member  12 . That is, the inside of the housing  30  is divided into one above the other by the second stem rubber  34   b . Further, the spacer  34   c  having cross sectional shape of letter “T” is arranged between the first stem rubber  34   a  and the second stem rubber  34   b , for maintaining the gap between the two and for securing the simultaneous opening and the closing of the stem holes. The spacer  34   c  has a slit which communicates the inside with outside. 
         [0049]    When the stem  31  is lowered, the valve mechanism  22  opens the upper storage  14  to the outside through the first discharge passage composed of the upper communicating hole  35   a  of the housing  30 , the first stem hole, and the first stem passage  31   a ; and the lower storage  15  to the outside through the second discharge passage composed of the pipe  16 , the bottom hole  35   b  of the housing  30 , the second stem hole, and the second stem passage  31   b . And because the inside space of the housing  30  is partitioned into two by the second stem rubber  34   b , the first content  17  in the upper storage  14  and the second content  18  in the lower storage will not be mixed until discharged outside. And both contents can be mixed after dispensed outside. Such a two-liquid independently dispensing type valve mechanism is also disclosed in Patent document 1. Further, the dispense amount of each content can be controlled by the amount of smallest sectional area of each passage communicating each storage with the outside, and the inner pressure of each storage. For example, when both storages have same inner pressure, the dispensing amount can be equalized by equalizing the smallest sectional area. 
         [0050]    The first content  17  charged in the upper storage  14  includes the liquid concentrate G 1  having beneficial effect and the propellant for dispensing the liquid concentrate G 1  outside, and the second content  18  charged in the lower storage  15  includes the liquid concentrate G 2  having beneficial effect and the propellant for dispensing the liquid concentrate. 
         [0051]    The first liquid concentrate G 1  of the first content  17  and the second liquid concentrate G 2  of the second content  18  are stored separately and mixed when in use. For example, two-liquid reactive oxidation hair dye composed of a first liquid concentrate including color dye such as paraphenylenediamine, etc., and a second liquid concentrate including oxidant such as hydrogen peroxide, etc., which oxidize the color dye; two-liquid reactive cream (moisturizing cream, cleansing cream, massage cream, etc.) or two-liquid reactive foam (shaving, treatment, etc.) composed of a first concentrate of none aqueous liquid including mineral salt such as magnesium chloride, etc., and a second concentrate of water which reacts with the mineral salt, where the heat is generated when reacted; two-liquid reactive foam (face wash foam, shampoo foam, etc.) and two-liquid reactive lotion (cosmetic lotion, tonic lotion, etc.) for good blood circulation composed of a first concentrate including organic acid such as citric acid, etc., and a second concentrate including carbonate such as sodium carbonate, etc., where the carbon dioxide is generated by degradation of the carbonate with the acid, may be cited. 
         [0052]    Further, two-liquid reactive gel (usage is not limited, hair cosmetic gel, anti-inflammatory analgesic gel, cooling gel, etc.) which thickens by neutralization composed of a first concentrate including water soluble polymer which thickens in alkali condition such as carboxy vinyl polymer, etc., and a second concentrate including alkali solution neutralizing the water soluble polymer; two-liquid reactive gel (usage is not limited, hair cosmetic gel, anti-inflammatory analgesic gel, cooling gel, etc.) which thickens by neutralization composed of a first concentrate including water soluble polymer which thickens in acidic condition such as plycrylate-1, etc., and a second concentrate including acidic solution neutralizing the water soluble polymer; two-liquid reactive cream or foam having a first concentrate including polyalcohol such as glycerin, ethylene glycol, etc., and a second concentrate including small amount of water which reacts with the polyalcohol generating the heat; or two-liquid non reactive agents used in order such as shampoo and hair conditioner, or cleansing cream and skin care cream, etc., may also be cited. 
         [0053]    At least one of the propellants is a liquefied gas and is charged in the storage. For the liquefied gas, liquefied petroleum gas, dimethyl ether, hydrofluoroolefin and mixture of any may be used. Liquefied gas may be charged in both of the storage (see  FIG. 1 ) and it may be stored only in either one. When concentrate including the liquefied gas is dispensed outside, the liquefied gas expands and the liquid concentrate can be dispensed in a foam, in a soft gel with small bubbles (sparkling gel), or in a soft cream with small bubbles (sparkling cream). If the contents are discharged in a foam, in soft gel with small bubbles, or in soft cream with small bubbles, the drip off can be prevented and blending is easy. Further, it may be sprayed in fine mist. For the propellant of the other concentrate, the pressurized gas such as nitrogen gas, carbon dioxide gas, air, etc. may be used. 
         [0054]    The two-liquid discharge container  10  of  FIG. 1 , is an aerosol container used in upside down condition, in which neither the dipping tube communicating the liquid phase of the contents in the upper storage  14  with the valve nor the dipping tube communicating the liquid phase of the content in the lower storage  15  with the valve were applied. And dispensing member (push button) B is attached to the stem  31 , when in use. Therefore, when discharging the contents from the storages, it is turned upside down. That is, the liquid phases of each concentrate G 1 , G 2  and liquid phase of each liquefied gas L 1 , L 2  in each storages  14 ,  15  will be moved to the lower side, that is the upper side when in upstand condition. And the first content  17  in the upper storage  14  is flowed into the upper space in the housing  30  through the communicating hole  35   a  of the lateral wall of the housing  30 . Also, the second content  18  in the lower storage  15  is flowed into the lower space in the housing  30  through the pipe  16 . Because the depressed portion  20   c  is formed on the partition wall portion  20 , the second concentrate G 2  can be flowed smoothly despite the high degree of viscosity. 
         [0055]    At this condition, the dispensing member B fixed to the stem  31  is pushed downward. Therefore, the first concentrate G 1  and the liquid phase of the first liquefied gas L 1  are discharged outside from the upper storage  14  through the first stem passage  31   a  and dispensing member B. It is preferable to shake the container body  11  before operating, for mixing the concentrate and the liquid phase of the liquefied gas. And at the same time the first content  17  is discharged outside from the upper storage  14 , the second content  18  is discharged outside from the lower storage  15  through the second stem passage  31   b  of the stem  31  and the dispensing member B. The contents  17 ,  18  will change into desired discharging state of foam, soft gel with small bubbles or soft cream with small bubbles, due to the expansion of the liquefied gas when discharged outside. And at the same time the contents are discharged, it is to be mixed. Therefore, the mixture can be used according to the intended use, such as two-liquid hair dye applied to the hair, 
         [0056]    Because, the two-liquid discharge container  10  of  FIG. 1  does not equipped with the dip tube which directly communicates with the liquid phase of the contents stored in the storages  14 ,  15 , the first concentrate G 1  and the second concentrate G 2  are positioned on the lower side of storages. And between two concentrates there is the gas phase of the liquefied gas L 2  charged in the lower storage  15 . Therefore, the liquid phase of the first content  17  infiltrates the partition wall member  12  and reacts with the second content  18  can be prevented, and the degradation of the product can be prevented. Further, since this is a discharge container for inverted use, the liquid content will not exists in the second passage  31   b  (inside of the housing  30  or pipe  16 ), because the second passage  31   b  will be filled with the gas phase of the liquefied gas L 2  in standup condition. Therefore it prevents the second content to infiltrates the housing or the pipe and prevents the reaction between the first content  17  and the second content  18 . The dispensing member B, such as the spout, push button, etc. can be cleaned after unfixing it. 
         [0057]    For the method to charge the contents into the two-liquid discharge container  10  of  FIG. 1 , for example, the contents may be charged by charging the second concentrate G 2  into the lower storage  15 , fixing the partition wall member  12  to the restriction portion, charging the first concentrate into the upper storage  17 , fixing and sealing the valve assembly  13  to the container body, and charging the propellant from stem  31 . The liquefied gas (propellant) L 1 , L 2  can be independently charged through each discharge passage from the stem to storages  14 ,  15 , because the first discharge passage from the first stem passage  31   a  of the stem  31  to the upper storage  14  and the second discharge passage from the second stem passage  31   b  of the stem  31  to the lower storage  15  of the valve mechanism are independent to each other. And the liquefied gas may be simultaneously charged. Further, the concentrate may also be charged through the valve, after the partition wall member  12  and the valve assembly  13  are fixed to the container body. Moreover, the charging of the liquefied gas into the upper storage  14  may be achieved by under-cup charging. In addition, it may be charged by mixing the concentrate and the liquefied gas in a cooled or a cooled high pressure condition where the vaporization of the liquefied gas is controlled. That is, by charging the second content  18  into the lower storage  15 , closing the lower storage  15  with partition wall member  12 , charging the first content  17  into the upper storage  14 , and closing the container with the valve assembly  13 . 
         [0058]    The two-liquid discharge container  38  of  FIG. 2  has a pouch  39  which communicates with the upper communicating hole  35   a  of the housing  30  in the upper storage  14 . The container body  11  and the partition wall member  12  are same as those of  FIG. 1 . This two-liquid discharge container  38  also is used in inverted (upside down) condition. The pouch  39  is made of a laminated material composed of the metal foil and the synthetic resin film. The pouch is manufactured by overlapping the laminated films and adhering the edge portions to form a bag. However, a bag may be formed by folding back one laminated sheet and adhering the three sides. The pipe  16  of the partition wall member  12  is to be sandwiched between two laminated sheets. Further in this embodiment, the housing of the valve mechanism is made to be double layer structure with an inner housing  30   a  and a tubular outer housing  30   b  formed outside of the inner housing  30   a  with a gap. The gap between the inner housing  30   a  and the outer housing  30   b  communicates with the space between the first stem rubber  34   a  and the second stem rubber  34   b  through the upper communicating hole  35   a . A gas-impermeable tube, especially metal tube  16   b  such as stainless steel tube may be arranged in the inner surface of the pipe  16 . 
         [0059]    The bottom of the outer housing  30   b  is sandwiched between the two laminated sheets structuring the pouch  39  and adhered. Therefore, the upper communicating hole  35   a  can be communicated with the pouch  39  through the space in the outer housing  30   b . The outer housing  30   b  may be configured to be in spindle shape in planar view, or in flattened shape to have the pouch  39  to be adhered easy. Further, a flattened protrusion  40  configured to be in plate shape or to be in spindle shape in planar view, may be provided on the upper surface of the partition wall portion  20  of the partition wall member  12 , and have the protrusion  40  to be sandwiched between the two sheets of the pouch  39  and adhered. 
         [0060]    Moreover, in this embodiment of  FIG. 2 , the outer housing  30   b  and the pipe  16  are to be arranged concentrically. However, in the case where the outer housing  30   b  and the pipe  16  are arranged in parallel, the pouch  39  may be arranged outside of the pipe  16 , for example the bottom of the outer housing  30   b  is closed with the bottom plate and the communicating member (such as numeral  59  of  FIG. 7 ) is fixed between the bottom plate and the pouch. In this case, the content stored in the pouch  39  infiltrating the pipe  16  may be prevented. 
         [0061]    The space lower than the second stem rubber  34   b  which communicates with the lower storage  15  through pipe  16  is same as the two-liquid discharge container  10  of  FIG. 1 . 
         [0062]    By fixing the upper part of the pouch  39  to the outer housing  30   b  and fixing the lower part of the pouch  49  to protrusion  40  of the partition wall member  12 , the pouch  39  can be prevented from being bended and trail down and can be kept stably when two-liquid discharge container  38  is in inverted condition. The inside of the pouch  39  is filled with the first concentrate G 1  of cream or liquid. The space between the container body  11  and the pouch  39  is filled with the propellant P such as pressurized gas. However, it may be liquefied gas. The second content  18  that is second concentrate G 2  and the liquefied gas L 2  charged in the lower storage  15  is substantially same as the two-liquid discharge container  10  of  FIG. 1 . In this embodiment, the first concentrate G 1  in the pouch and the second content  18  in the lower storage are simultaneously discharged, while the discharging state of the first concentrate may be changed to the foam, etc. by the vaporization of the liquefied gas L 2  of the second content. 
         [0063]    For the method to charge the content in the two-liquid dispense container  38  of  FIG. 2 , for example, the contents may be charged by charging the second concentrate G 2  in the lower storage  15 , fixing the partition wall member  12 , charging the propellant in the upper storage  15  by under-cup charging method, and fixing the valve assembly  13  to the container body. The contents are charged further, by vacuuming the air in the pouch  39  by lowering the stem  31 , charging the liquefied gas L 2  into the lower storage  15  through the second stem passage  31   b  of the stem  31 , and by charging the first concentrate G 1  into the pouch  39  through the first stem passage  31   a.    
         [0064]    The two-liquid discharge container  42  of  FIG. 3  is equipped with the pouch  39  housed in the lower storage  15  opposite to the two-liquid discharge container  38  of  FIG. 2 , and the propellant P of pressurized gas is charged between the container body  11  and the pouch  39 . The upper storage  14  of the two-liquid discharge container  42  is same as the two-liquid discharge container  10  of  FIG. 1  and the lower storage  15  is same as the two-liquid discharge container  38  of  FIG. 2 . This two-liquid discharge container  42  also is used in inverted state. The pipe  16  is extended downwardly in the partition wall member  20  and the bottom of the pipe is engaged with the connecting member  16   d  having the flattened portion  16   c  of spindle shape in planar view. The connecting member  16   d  is sandwiched and adhered between the two sheets composing the pouch  39 . Therefore, the top of the pouch  39  can be tightly engaged with the pipe  16 . In this embodiment, because the second concentrate G 2  exist in the pipe  16  in stand-up condition, it is preferable to apply the pipe  16  made of synthetic resin pipe in which the metal tube (note  16   b  of  FIG. 2 ) such as stainless steel tube, is provided inside the synthetic resin pipe. 
         [0065]    For the method to charge the content in the two-liquid discharge container  42  of  FIG. 3 , for example, the contents may be charged by charging the propellant P into the lower storage  15  by under-up charging, fixing the partition wall member  20 , and fixing the valve assembly  13  to the container body  11 . The contents are charged further, by vacuuming the air in the pouch  39  and vacuuming the propellant in the upper storage  14  by lowering the stem  31 , by charging the second concentrate G 2  into the pouch  39  through the second stem passage  31   b  of the stem  31 , and by charging the first concentrate G 1  and the liquefied gas L 1  into the upper storage  14  through the first stem passage  31   a  of stem  31 . 
         [0066]    The two-liquid discharge container  43  of  FIG. 4  is a device which mixes two liquids in the container body  11  and dispenses the mixture, unlike said two-liquid discharge containers  10 ,  38 ,  42 . That is, the two-liquid discharge container  43  has a partition wall member which partitions the upper storage  14  and the lower storage  15  and which can operate the opening and closing of the pass between the upper storage and the lower storage. For example, a balloon  44  which can expand and shrink is applied. Further, it has an opening valve  46  which discharge the gas in the balloon by operation, other than the dispense valve  45  dispensing the mixed content outside. A soft tube  44  or pipe communicates the balloon  44  with the opening valve  46 . In the balloon  44 , a pressurized gas of high stability, such as nitrogen gas, argon gas, etc. may be charged other than the air. 
         [0067]    As for the valve assembly having the dispense valve  45  and the opening valve  46 , it is preferable, for example, that it is assembled using one valve holder  48  holding two valves  45 ,  46  and cover cap  49  fixing the valve holder  48  to the container body  11 . For such a double valve assembly, a valve assembly which simultaneously dispenses two contents disclosed in FIG. 14 of Patent document 2 may be substituted. In the embodiment of the FIG. 14 of Patent document 2, one dispensing member (push button) is fixed to the double valve assembly, however, in the valve assembly of  FIG. 4 , the valves are structured to be operated independently that is the dispense member  50  is fixed to the dispense valve  45  and the operate member  51  is fixed to the opening valve  46 . 
         [0068]    To use the two-liquid discharge container  43  of  FIG. 4 , the gas in the balloon  43  must be removed by lowering the operate member  51  of the opening valve  46  for the upper storage  14  and the lower storage  15  to be communicated. And then the first content  17  and the second concentrate G 2  are mixed by shaking the container body  11 . Next the dispense member  50  is lowered to open the dispense valve  45  in inverted state, and the mixed content is discharged outside. For such a mixed content, the contents shown in the two-liquid discharge container  10  of  FIG. 1  can be applied. Further, because, the first content  17  and the second concentrate G are mixed in the container body  11 , the propellant is to be charged in either of contents, and the discharging state can be changed with just one propellant. However, it is preferable to have the liquefied gas L 1  charged in upper storage  14  storing the first content  17 , and charge only the second concentrate G 2  and not charge the propellant in lower storage  15  storing the second content. Therefore, the charging work can be simplified. 
         [0069]    That is, in order to store the content, the second concentrate G 2  is to be charged in the lower storage  15  and the valve assembly is to be fixed to the container body. Further, the lower storage  15  is closed by charging the gas into the balloon  44  through the opening valve  46  and expands the balloon  44 . The space, in which the second concentrate G 2  is not filled, is filled with air. In this condition, the lower storage  15  is not pressed, therefore the fixing operation of the balloon  44  and the closing operation of the lower storage  15  can be achieved easy. After that the first concentrate G 1  is charged into the upper storage  14  through the dispense valve  45  and the liquefied gas is also charged. In this two-liquid discharge container  43  also, the first concentrate G 1  and the second concentrate G 2  is stored in a condition where the air and the balloon  44  filled with the gas is in between. Therefore, reaction between the contents due to the infiltration and degradation can be prevented, in contradistinction to the two concentrate adjacent to each other through the synthetic resin sheet. However, the propellant may be charged into the lower storage  15  and have the inner pressure to be same like the upper storage. In this case, the inner pressure of the upper and lower storage balances the balloon to be stabilized. 
         [0070]    In all of said embodiments, the two-liquid discharge containers were used in inverted state. However, the present invention may be used in stand-up condition. The two-liquid discharge container  52  of  FIG. 5  is used in stand-up condition, which comprises a dip tube  53  extending downward from the metal tube  16   b  to the bottom of the lower storage  15 . Other structures are substantially same as the two-liquid discharge container  38  of  FIG. 2 . In this two-liquid discharge container  52 , when the valve mechanism  22  is operated, the first concentrate G 1  is discharged from the pouch  39  due to the pressing of the propellant P and the second content in the lower storage is discharged from the stem  31  of the valve mechanism  22  through the dipping tube  53  and inner housing  30   a  due to the pressing of the liquefied gas L 2 . The first concentrate G 1  and the second concentrate are changed into foam or into bubbles by the liquefied gas L 2 . 
         [0071]    The two-liquid discharge container  54  of  FIG. 6  is made to be used in stand-up condition, in which dipping tubes  55 ,  56  are provided respectively in storages and neither have the pouch. That is, in this embodiment, the dipping tubes  55 ,  56  construct the first discharge passage and the second discharge passage of the discharge passage. The valve assembly  13  is substantially same as the double valves type of two-liquid discharge container  43  of  FIG. 4 , and two valves  45   a ,  45   b  for upper storage  14  and lower storage  15 , respectively are held by the valve holder  48  and the cover cap  49 . The dipping tube  55 ,  56  arranged in parallel communicates each storage  14 ,  15  with the valves  45   a ,  45   b , respectively. One dispensing member is fixed to stems  31 ,  31  of two valves. The dipping tubes  55 ,  56  maybe made of soft material and maybe made of hard material, however the dipping tube  56  which communicates the valve  45   b  with the lower storage  15  is preferable to be metal tube such as stainless steel tube for shutting the inside from the first content  17 . In this two-liquid discharge container  54 , not only the partition wall portion  20  but also the gas phase of the liquefied gas L 2  in the second storage  15  is positioned between the first concentrate G 1  of the upper storage  14  and the second concentrate G 2  of the lower storage  15 . Therefore, the first concentrate and the second concentrate can be kept for long period of time without degrading. 
         [0072]    The two-liquid discharge container  58  of  FIG. 7  has a pouch  39  in upper storage  14  like two valves type two-liquid discharge container  54  of  FIG. 6 . The pouch  39  is connected to the valve  45   a  for upper storage using a tubular connecting member  59 . In this embodiment, the upper tube portion  59   a  of the connecting member  59  is inserted in the housing  30  of the valve  45   a , and the upper end portion of the pouch  39  is adhered to the outer periphery of the connecting member  59 . The pipe  60  is engaged to the lower portion of the connecting member  59 , so that the passage is secured even when the pouch is folded when discharging. Further, in order to secure the passage, plural of introducing holes  61  are formed on the pipe  60 . 
         [0073]    And like shown in  FIG. 8 a   , horizontally long pouch  39  is employed and the connecting member  59  is fixed to the pouch  39  displacing from the center of the pouch  39 . Therefore, like shown in  FIG. 8 b   , the pouch can be positioned adjacent to the space near the dipping tube  57  of the lower storage without deeply bending the pouch and secure the volume of the pouch  39 . Like in this embodiment, by positioning two storages up and down, the height of each storage can be structured to be low, but the volume can be gained by arranging the pouch horizontally long. The content tends to remain in the corner portion in the horizontally long pouch  39  therefore, it is preferable to form the corner portion  62  to be round and not form the corner edge when adhering two sheets. 
         [0074]    The two-liquid discharge container  70  of  FIG. 9  and the two-liquid discharge container  90  of  FIG. 10  discharges the contents in upstand state, where the first tube passage  71   a  connecting the valve mechanism  22  with the upper storage  14  and the second tube passage  71   b  connecting the valve mechanism  22  with the lower storage  15  are provided concentrically. Both two-liquid discharge containers has an air between the second content stored in the lower storage  15  and the first content stored in the upper storage  14 , therefore the chance that contents of both storages infiltrates to other storage and contents are to be mixed, is small. 
         [0075]    The two-liquid discharge container  70  is equipped with a container body  11  made of synthetic resin, a partition wall member  72  dividing the inside space of the container body into one above the other, and a valve assembly  73  which closes the upper opening of the container body  11  and operates the opening and closing of the passages between each storage and outside. The dispensing member  74  is fixed to the valve assembly  73 . The inner diameter of the constriction portion  11   e  is substantially same as the inner diameter of the neck portion  11   c  and the inner diameter of the parison, other than that it is substantially same as the container body  11  of  FIG. 1 . However, the inner diameter of the constriction portion  11   e  may be smaller than the neck portion  11   c.    
         [0076]    The partition wall member  72  has a partition wall portion  20  of column shape where it engages with the inner surface of the constriction portion  11   e  of the container body  11 , and the inner dipping tube  72   a  which penetrates the partition wall portion  20  up and down. The lower end of the inner dipping tube  72   a  extends to the bottom of the lower storage  15 . The partition wall portion  20  is substantially same as the partition wall portion  20  of partition wall member  12  of  FIG. 1 . In this embodiment, the partition wall portion  20  and the dipping tube  72   a  are formed integrally, but may be formed separately like in  FIG. 5 . 
         [0077]    The valve assembly  73  is equipped with the valve mechanism  22 , and the mounting cover  75  fixing the valve mechanism  22  to the container body  11 . The valve mechanism  22  has housing  30 , stem  31 , and spring  32  and is substantially same as the valve mechanism  22  of  FIG. 1 , except that the center hole (second stem passage  31   c ) of the small diameter tube of stem  31  is communicated with the lower storage  15  through the second stem hole (lower stem hole) and the second tube passage  71   b  and the gap between the large diameter tube and the small diameter tube (first stem passage  31   d ) is communicated with the upper storage  14  through the first stem hole (upper stem hole) and the first tube passage  71   a . Further, on the outer peripheral of the housing  30 , the upper communicating hole  35   a  is formed penetrating the large diameter portion  30   b . And the outer dipping tube  80  communicating the upper communicating hole  35   a  of the housing  30  with upper storage  15  is engaged to the outer peripheral of the large diameter portion  30   b  of the housing  30 . And the outer dipping tube  80  is extended to the vicinity of the bottom of the upper storage  14 . That is the outer dipping tube  80  houses the inner dipping tube  72   a  and the outer dipping tube  80  and the inner dipping tube  72   a  are positioned concentrically. The first tube passage  71   a  is a tubular space between the outer dipping tube  80  and the inner dipping tube  72   a  and the second tube passage  71   b  is a column space. The inside of the inner dipping tube  72   a  will be filled with the content of the lower storage once the valve is opened, it is preferably to provide the metal tube inside the inner dipping tube  72   a  made of metal pipe or synthetic resin pipe, like in two-liquid discharge container  42  of  FIG. 3 . 
         [0078]    The mounting cover  75  directly holds the valve mechanism  22 . Specifically, it has a valve holding portion  75   a  which covers the top opening of the housing  30  and pinches or sandwiches the upper flange portion  30   a  of the housing  30 , and a container holding portion  75   b  which is engaged to the bottom of the valve holding portion  75   a , which covers the top of the container body  11  through the sealing member  25   a , and in which the bottom is engaged with the flange  11   d  of the container body. 
         [0079]    The dispensing member  74  has a box like shape and comprises a stem engaging portion  74   a  formed on the bottom for inserting the stem  31  and a tip engaging portion  74   b  formed on the front for inserting the nozzle tip  78 . The dispensing member  74  is for independently discharging two contents. Specifically, the stem engaging portion  74   a  is structured with a small diameter portion  76   a  which receives the small diameter tube of the stem  31 , and a large diameter portion  76   b  formed concentrically below the small diameter portion and which receives the large diameter tube of the stem  31 . The stem engaging portion  74   a  and the tip engaging portion  74   b  are connected respectively through the first dispensing member passage  77   a  extending forward from the top of the small diameter portion  76   a  and the second dispensing member passage  77   b  extending forward from top of the large diameter portion  77   b.    
         [0080]    The nozzle tip  78  has a column shape and comprises a center hole  78   a  which communicates with the first dispensing member passage  77   a  and a outer peripheral channel  78   b  which communicates with the second dispensing member passage  77   b . However, a small diameter portion  79   a  may be formed on the base side and plural of outer peripheral channel  78   b  may be formed, like shown in  FIG. 9 b   . Further, the nozzle tip may be made to be conically shaped where the outer diameter decreases in front direction. By having the nozzle tip to be in conically shape, the first content is gather to the center and can be easily mixes with the second content after discharged from the nozzle tip. 
         [0081]    In the two-liquid discharge container  90  of  FIG. 10 , a constriction portion  11   e  of the container body  11  is curved inwardly, and the partition wall member  91  having elasticity is inserted in the constriction portion  11   e . The constriction portion  11   e  is formed by narrowing using the die, etc., when blowing the parison. Other configuration is substantially same as the two-liquid discharge container  70  of  FIG. 9 . 
         [0082]    The partition wall member  91  is composed of a tubular main body  92  formed of elastic or elastomeric material having an outer diameter larger than an inner diameter of the constriction portion  11   e , and a dipping tube  93  in which a tubular hard material is inserted. On top of the main body  92 , a flange portion  92   a  which protrudes outwardly in radial direction is formed. A spherical portion  93   a  which protrudes outwardly in radial direction is formed on the lower part of the dipping tube  93 . The spherical portion  93   a  is inserted into the main body  92  and connects the main body  92  with the dipping tube  93  hermetically. Further, also in the two-liquid discharge container  90 , the inside of the dipping tube  93  will be filled with the content of the lower storage  15  once the valve is opened. Therefore, it is preferably to use a metal pipe or a synthetic resin pipe in which the metal pipe such as stainless steel pipe is provided on the inner surface. 
         [0083]    The main body  92  of the partition wall member  91  is inserted in the container body  11  from the opening of the container body  11 , and then inserted in the constriction portion  11   e , where the flange portion  92   a  of the main body  92  is hooked to the constriction portion  11   e . And the dipping tube  93  is inserted in the center hole of the main body  92 , and the main body  92  is pushed outwardly by the spherical portion  93   a . However, it may be inserted into the container body after the main body  92  and the dipping tube  93  is connected and the fixing method is not limited. The inner surface of the constriction portion  11   e  may be formed to be tube surface like that of  FIG. 1 . In this case also, the dipping tube and the partition wall member can be hermetically engaged by forming the partition wall member with the elastic material. 
         [0084]    In either of embodiments, the constriction portion  11   e  is formed on the barrel portion of the container body  11 . And the inner diameter of the constriction portion  11   e  is made to be substantially same as the inner diameter of the neck portion  11   c  or smaller (inner diameter of the constriction portion≦inner diameter of the neck portion  11   c ). Therefore, the partition wall member  20  which can be inserted from the neck portion, can be stably engaged with the upper step of the constriction portion  11   e . However the inner diameter of the constriction portion may be configured to be larger than the inner diameter of the top neck portion  11   c  of the container body  11  (inner diameter of the constriction portion≧inner diameter of the neck portion  11   c ). For example, in the case where the partition wall member  91  which enlarges the main body  92  by inserting the spherical portion  93   a  of the dipping tube  93  into the center hole, the partition wall member may be assembled by inserting the partition wall member  91  in which the size of the partition wall member  91  is reduced, hooking the flange portion  92   a  of the main body  92  to the constriction portion  11   e  of the container body  11  after inserting, and inserting the spherical portion  93   a  into the main body  92 . The spherical portion  93   a  widens the main body  92  by inserting and as a result the inside of the container body  11  is divided into two storages  14 ,  15 . 
         [0085]    The constriction portion  11   e  of the container body may be omitted if the partition wall member  20  can be stably fixed and can be inserted through the opening. For example, when the inner diameter of the neck portion is larger than the inner diameter of the barrel portion, the two or more storages can be formed by arranging the partition wall member having a leg portion which holds or supports the partition wall member in the middle of the barrel portion. 
         [0086]    The container main bodies  11  of previous embodiments are made of synthetic resin formed by blow molding, therefore it can be manufactured cheap. However, it may be manufactured by injection molding and or it may be assembled with plural components made of other material such as metal, etc. In that case, the container body may be formed to be rigid and with higher strength than the container body of blow forming. Further, when the metal is used, the inner surface is preferably to be coated with the synthetic resin liner or synthetic resin coat. 
         [0087]    The two-liquid discharge container  100  of  FIG. 11  is equipped with a container body  101  made of glass. Specifically, it is an aerosol container equipped with the container body  101  made of glass, a partition wall member  12  dividing the inside space into one above the other, a valve assembly  103  closing the upper opening of the container body  101  and operating the opening and closing of the passage between the inner space and the outside. The partition wall member  12  is substantially same as the partition wall member  12  of  FIG. 1 , other than that the bottom of the partition wall portion  20  is positioned in inner tube surface of the constriction portion  105 . Because the bottom of the partition wall portion  20  is in the inner tube surface, the content will not remains between the partition wall portion  20  and the container body  101 , when used in inverted condition. This can also be said in the two-liquid discharge container  10  of  FIG. 1 , the two-liquid discharge container  38  of  FIG. 2 , and the two-liquid discharge container  52  of  FIG. 5 . 
         [0088]    The container body  101  comprises a barrel portion, a shoulder portion, and a neck portion, where the neck portion has a flange portion, and where the barrel portion  104  has a tubular constriction portion  105  in between. It is pressure resistance container having a gourd-shaped. The constriction portion  105  vertically divides the barrel portion  104  into two in an upper barrel portion  104   a  and a lower barrel portion  104   b . Both the upper barrel portion  104   a  and the lower barrel portion  104   b  are curved gradually protruding outside, therefore, the shape of the container body  101  is more closer to the gourd than the container body  11  of  FIG. 1 . By forming the upper barrel portion  104   a  and the lower barrel portion  104   b  closer to the globe, strength can be given against the external force. Especially, because it is made of glass, it is formed to be shatter proof. 
         [0089]    Further, the synthetic resin coat  101   a  is provided on the outer surface. By providing the synthetic resin coat  101   a  on the outer surface, it lessen the impact to the container and prevents the broken pieces to spattered when crashed, therefore it is safe. 
         [0090]    As for the glass, a silicate glass, a borate glass, and an acrylic glass may be applied. Further, a composite material in which the miniaturized glass is dispersed in the melted synthetic resin and formed may be used. 
         [0091]    As for the synthetic resin coat  101   a , a synthetic resin such as a polyvinyl chloride, polyethylene terephthalate, etc. may be cited. The synthetic resin coat may be formed by cooling the dipped glass container which is dipped in the melted synthetic resin. Further, to firmly attach the synthetic resin coat to the surface of the container body, it is preferable to provide a hole on the synthetic resin coat for vacuuming the air between the synthetic resin coat and the container body. 
         [0092]    Because the container body  101  is made of glass, the influence from the content is small like the container body made of synthetic resin. This container is suitable for storing the first agent of the two-liquid type hair dye which change or resolve the property of the synthetic resin or for safely storing dimethyl ether used as liquefied gas. Further, it can store a gas which infiltrates the synthetic resins. As well, the container body  101  may be used as the container body of  FIG. 2, 5, 7 . 
         [0093]    The valve assembly  103  is equipped with a valve holder  106  fixed to the opening of the container body  101 , a valve mechanism  107  fixed to the center of the valve holder  107 , and a mount cover  23  fixing the valve holder  106  to the container body  101 . The mount cover  23  is substantially same as that of mount cover  23  of  FIG. 1 . 
         [0094]    The valve holder  106  has an outer tube portion (cylindrical wall)  106   a  inserted into the neck portion of the container body  101 , a flange  106   b  protruding outwardly from the top of the outer tube portion and which engages with the top of the flange of the container body  101 , an inner tube portion  106   c  storing the valve mechanism  107  and having a ceiling, and a connecting portion  106   d  connecting the top of the outer tube portion  106   a  with the top of the inner tube portion  106   c . Unlike the valve holder  21  of  FIG. 1 , the connecting portion  106   d  of the valve holder  106  is positioned on top of the outer tube portion  106   a  and on top of the inner tube portion  106   c . Further, between the flange  106   b  of the valve holder  106  and the top of the neck portion of the container body  101 , a ring shaped gasket is provided. The valve holder is formed of synthetic resin. The sealing structure between the container body  101  and the valve holder  106  may be formed by providing the O-ring between the outer tube portion  106   a  of the valve holder  106  and the inner surface of the neck portion of the container body  101  like the sealing structure of the two-liquid discharge container  54  of  FIG. 6  and the two-liquid discharge container  58  of  FIG. 7 . 
         [0095]    The valve mechanism  107  communicates the second stem hole (lower stem hole) with the center hole of the small diameter tube of stem  31  and communicates the first stem hole (upper stem hole) with the gap between the large diameter tube and the small diameter tube, like the valve mechanism  22  of the two-liquid discharge container of  FIG. 9 . 
         [0096]    In this two-liquid discharge container  100 , the first discharge passage and the second discharge passage are communicated with the gas phases of each storage, respectively, when in upstand state. Therefore, the contact of the first content and the second content can be prevented and both can be stored stably. 
         [0097]    The two-liquid discharge container  110  of  FIG. 12  is for using in inverted state, and comprises a container body  111  having two-layer structure made of synthetic resin. Especially, it is an aerosol container which comprises the container body  111  having the constriction portion, the partition wall member  12  which vertically divides the inner space of the container body, and the valve assembly  74  which closes the upper opening of the container body  111  and which operates the opening and closing of the passage between the inner space and the outside. The partition wall member  12  is substantially same as the partition wall member  12  of  FIG. 1  except for that the bottom of the partition wall portion  20  of the partition wall member  12  has a engaging protrusion  12   a  which clip on and engages with the inside wall of the lower storage  15 . The valve assembly  73  is substantially same as the valve assembly  73  of  FIG. 9  except for that it lacks the outside dipping tube. 
         [0098]    The container body  111  is formed by closely attaching two containers (inner container  113 , outer container  114 ). For example, it can be manufactured by forming an outer preform for outer container and an inner preform for inner container by injection molding, preparing two layer preform by inserting the inner preform in the outer preform, forming the outer container  114  and the inner container  113  simultaneously by biaxial stretching blow molding from the two layer preform. By this manufacturing method, the container body  111  having the outer surface of the inner container  113  closely attached to the inner surface of the outer container  114 , can be manufactured. However, it can be prepared by forming the outer container  114 , and inserting the inner container  113  by squashing or a synthetic resin coating can be applied to the inner surface of the outer container  114  as the inner container  113 . 
         [0099]    By having the container body  111  in two-layer structure, the durability of both the upper storage and the lower storage against the contents can be enhanced, and the strength can be enhanced. That is, the inner container  113  can be formed with the material durable against the content, and the outer container  114  can be formed with the material which is strong against the inner pressure. For example, in the case where the first agent of the hair dye including the oxidation dye is stored in the upper storage  14  and the second agent of the hair dye including the oxidant is stored in the lower storage  15 . A material durable against both contents such as polyolefin including polypropylene, polyethylene, etc., polyamide including nylon, etc. can be cited as a material for the inner container. And a material having high strength and can reinforce the inner container such as polyester including polyethylene terephthalate, etc., can be cited as a material for the outer container. 
         [0100]    The present invention of two-liquid discharge container stores two liquids and dispenses two liquids individually or after mixing. However, unless the effects are not interfered, it may be configured to have three liquids stored and dispensed. For example, three storages may be provided by positioning partition wall members in between each border, or inserting two or more pouch in the storage.
