A neck portion 19 and a lid portion 20 provided to close the neck opening.
A partition wall 15 extending upward from a line segment passing through the center of the bottom 16 is formed on the bottom 16 so as to divide the bottom 16 in half. That is, the partition wall 15 divides the lower space (stock solution chamber) of the pressure vessel 11 into two parallel semi-cylindrical spaces (stock solution storage portions S1 and S2). The height of the partition wall portion 15 is about half that of the body portion 17. The height of the partition wall 15 is preferably ¼ to ¾, particularly preferably 容器 3 to 2/3 of the pressure vessel.
In this embodiment, the partition wall 15 divides the stock solution storage portions S1 and S2 into the same volume, but the partition wall portion 15 is provided above a line segment that does not pass through the center of the bottom portion 16, and one stock solution storage portion is connected to the other. It may be larger than the stock solution storage part. In this case, the two stock solutions are discharged in an amount corresponding to the volume ratio in which they are stored. Therefore, the parallel stock solution storage units mean that at least two (plural) stock solution storage units having the same height are arranged at the same position (height).
Further, in this embodiment, the partition wall 15 is formed integrally with the bottom 16. However, it is good also as a separate body using a division member etc. like FIG.

It is formed by combining with 11b. In this embodiment, the upper end of the lower body 11a (the upper end of the lower portion of the trunk portion 17) and the lower end of the upper body 11b (the lower end of the upper portion of the trunk portion 17) are engaged with each other so as to engage with each other. They are joined by welding or bonding. However, as shown in FIG. 2d, the container body 11c is composed of a bottom portion 16 and a trunk portion 17, and a flange portion 19a is formed on the upper end of the trunk portion 17, and a flange portion 20b disposed above the flange portion 19a. The lid body 11d including the lid portion 20 provided with the above may be coupled by sandwiching the flange portion 19a and the flange portion 20b with the cover cap 14 (imaginary line). The container body 11c excludes the shoulder portion and the neck portion in order to allow the pressing member 12 to be inserted.
Such a pressure vessel 11 is formed from a synthetic resin such as polyethylene terephthalate, polybutylene terephthalate, polyamide, polyacetal. Further, when the pressure vessel 11 is made of a synthetic resin, it is preferable to make the pressure vessel 11 transparent or translucent so that the remaining amount can be confirmed and the vertical movement of the piston can be visually recognized.

  As shown in FIGS. 3a and 3b, the pressurizing member 12 includes a meniscus-shaped first piston 22 (left in the drawing), a meniscus-shaped second piston 23 (right in the drawing), and a connecting portion 24 that connects them. It consists of. Thus, since both the pistons 22 and 23 are integrated by the connection part 24 in the pressurization member 12, each piston 22 and 23 moves integrally, and 1st stock solution storage part S1 and 2nd stock solution storage part S2 Can be evenly contracted, and the stock solutions A and B can be discharged evenly.

  The first and second pistons 22 and 23 slide up and down the inner surface of the pressure-resistant container 11 and the partition wall 15 to reduce the above-described semicylindrical spaces (stock solution storage portions S1 and S2). The curved arc-shaped outer edge portions 22a and 23a of the first and second pistons 22 and 23 and the linear inner edge portions 22b and 23b rise upward. That is, the outer edge portions 22a and 23a and the inner edge portions 22b and 23b are in surface contact with the inner surface of the pressure-resistant container 11 and the partition wall portion 15, thereby improving the sealing performance and the guide performance. The first and second pistons 22 and 23 are respectively formed with support cylinders 25 that pass through the first and second pistons 22 and 23 and pass the dip tube 31 of the valve assembly 13.

  The support cylinder 25 is a cylinder that penetrates the first and second pistons 22 and 23 in the vertical direction, and is a part that slides with the dip tube 31. The first and second pistons 22 and 23 are provided at substantially the center, and the respective support cylinders 25 are opposed to each other with the partition wall 15 interposed therebetween. Since the support cylinders 25 are formed on the first and second pistons 22 and 23, even if the internal pressures of the stock solution storage portions pressed by the pistons 22 and 23 are different, for example, the first stock solution A and the second stock solution B Even if there is a difference in viscosity, the connecting portion 24 is prevented from being deformed and the pistons 22 and 23 are prevented from being inclined. At the upper end of the support tube 25, a guide portion 25 a is formed that expands in diameter upward to guide the insertion of the dip tube 31 into the support tube 25.

  The connecting portion 24 includes a connecting wall 24a extending in parallel with the partition wall portion 15 from the inner edges 22b and 23b contacting the partition wall portion 15 of the first and second pistons 22 and 23, and a connecting bridge 24b connecting the upper ends thereof. . The height of the connecting wall 24 a is substantially the same as or slightly higher than the height of the partition wall portion 15. And the partition part 15 is inserted in the clearance gap which consists of both the connection walls 24a and the connection bridge 24b. Therefore, a guide action is also generated in the connecting portion 24 and the partition wall portion 15. The connecting portion 24 and the partition wall portion 15 may not be brought into contact with each other, or a large gap may be formed between the connecting portion 24 and the partition wall portion 15. In that case, there is no guide action of the pistons 22 and 23. The connecting portion 24 is provided such that the first piston 22 and the second piston 23 are in contact with the upper surfaces of the respective stock solution storage portions S1 and S2 at the same time.

The pressurizing member 12 includes piston edges (outer edge portions 22a, 23a and inner edge portions 22b, 2
By providing a support in addition to 3b), the vertical movement of the pistons 22 and 23 is stabilized. Specifically, the dip tube 31 prevents the pistons 22 and 23 from tilting in the front-rear direction in FIG. 1 through the support cylinder 25, and the partition wall 15 through the connecting part 24 in the left and right sides of FIG. Prevents direction tilt.

  As shown in FIG. 3 c, the aerosol valve 13 has a cylindrical housing 26, a stem 27 that is accommodated in the housing 26 so as to be movable up and down, and an annular shape that inserts the stem 27 and seals the opening of the housing 26. The stem rubber 28, the spring 29 that constantly biases the stem 27 upward, the valve cap 30 that fixes the stem 27, the stem rubber 28 and the spring 29 in the housing 26, the housing 26 and the stock solution storage portions S1 and S2. A dip tube 31 is provided. An annular sealing material (O-ring) 32 that seals between the aerosol valve 13 and the valve holding portion 21 is provided on the outer periphery of the housing 26.

The housing 26 has a bottom portion 26a having a communication hole formed therein, and a stem rubber holding portion 26b is formed at the upper end of the inner surface. An annular locking portion 26c is formed on the outer periphery of the upper portion of the housing 26, and a sealing material holding step portion 26d whose diameter is reduced downward is formed on the lower portion. A locking step portion 26e having a reduced diameter is formed. At the lower end of the housing 26, a tubular tube connecting portion 26f that protrudes downward from the lower surface of the bottom portion 26a is formed so as to communicate with the communication hole of the bottom portion 26a of the housing.
The stem 27 is formed with a stem hole 27a on the side surface, and has an annular flange 27b that protrudes radially outward at the lower end and extends upward to contact the lower surface of the stem rubber 28.
The valve cap 30 is a cylindrical body having an upper bottom 30a that covers the upper portion of the housing 26, and an engaging claw 30b that engages with the aforementioned locking portion 26c is formed on the side surface. The lower end 30c extends straight downward.
The dip tube 31 is a cylindrical body that is inserted into the tube connecting portion 26f. The dip tube 31 passes through the pressurizing chamber S 3, passes through the support cylinders 25 of the first and second pistons 22 and 23 of the pressurizing member 12, and extends to the vicinity of the bottom 16 of the pressure resistant container 11. As a material of the dip tube 31, it is preferable to use a strong synthetic resin such as polypropylene or a metal having high corrosion resistance and high strength such as stainless steel in order to achieve the effect of the guide tube as described later.

  In the discharge container 10, two aerosol valves 13, a lid part 20 of the pressure-resistant container 11 in which a valve holding part 21 that holds them is formed, and a cover cap that fixes the aerosol valve 13 to the lid part 20 of the pressure-resistant container 11. 14 constitutes a valve assembly.

In the aerosol valve 13 configured as described above, the stem 27 is pushed downward, the annular flange 27b of the stem 27 is separated from the lower surface of the stem rubber 28, the seal is released, and the inside and outside of the housing 26 are disconnected. Communicate. In the aerosol valve 13, the seal is released when the annular flange portion 27 b is separated from the lower surface of the stem rubber 28. Therefore, it is easy to adjust the timing at which the seals of a plurality of aerosol valves are released, and the amount of depression of the stem 27 is affected. It is hard to receive. Further, since the stem hole 27a can be enlarged because it is sealed at a site different from the stem hole 27a, and the gap opened by the operation is large, the discharged stock solution is received when passing through the stem 27. The resistance is small and the control by the stem 27 is difficult. That is, the stock solution that has been simultaneously pushed out from the stock solution chamber at the same pressure and entered the housing 26 can be stably discharged to a constant amount.
In the aerosol valve 13 and the valve holding portion 21, the locking step portion 26 e of the housing 26 is engaged with the support step portion 21 a of the valve holding portion 21. The O-ring 32 held by the sealing material holding step portion 26d of the housing 26 and the rising wall 21b come into contact with each other to seal between the aerosol valve 13 and the valve holding portion 21. Further, the lower end of the valve cap 30 is inserted into the annular groove 21 c of the valve holding portion 21.

Returning to FIG. 1, the cover cap 14 covers the lid portion 20 of the pressure-resistant container 11, a mount portion 14 a that fixes the aerosol valve 13 to the pressure-resistant vessel 11, and a neck portion 19 of the pressure-resistant vessel 11 that expands from the mount portion 14 a. The flange portion 19a and the fixing portion 14b to be locked.
Two insertion holes through which the stem 27 of the aerosol valve 13 is passed are formed on the top surface of the mount portion 14a.
The fixing portion 14b is formed by bending the lower end of the cylindrical body inward in the radial direction and plastically deforming so as to sandwich the flange portion 19a of the pressure-resistant container 11 from above and below.

  As a method of filling the discharge container 10 with the stock solution and the pressurizing agent, an upper body 11b to which an aerosol valve 13 and a cover cap 14 are attached is prepared, and a first stock solution storage unit S1 and a second stock solution storage unit S2 of the lower body 11a. Are filled with the first stock solution A and the second stock solution B, respectively. Next, the pressurizing member 12 is inserted, and the upper surface of the stock solution is covered with the pressurizing member 12 while discharging air between the bottom surface of the pressurizing member 12 and the upper surface of the stock solution from the support tube 25. Thereafter, the dip tube 31 is inserted into the support cylinder 25 of the pressure member 12, and the upper body 11b is disposed on the lower body 11a. Subsequently, the pressurizing agent P is filled into the pressurizing chamber S3 from between the lower body 11a and the upper body 11b, and at the same time, the lower body 11a and the upper body 11b are fixed by welding or the like to obtain a discharge product.

The discharge container 10 uses the push buttons 35 (imaginary lines in FIG. 1) that press the two stems 27 at the same time to push down the stems 27 to open both the aerosol valves 13. Discharge. That is, when both the aerosol valves 13 are opened, the pressurizing agent P in the pressurizing chamber S3 presses both the pistons 22 and 23, and the first and second pistons 22 and 23 can slide downward. The stock solution storage portions S1 and S2 are contracted. At the same time, the two stock solutions A and B are supplied into the housing 26 through the dip tube 31 and discharged from the stem 27 to the outside through the push button 35. The stock solutions in both stock solution storage portions S1 and S2 are uniformly pressurized and stored, and the external force from each stock solution received by the partition wall portion 15 is balanced, so that the partition wall portion 15 may be deformed. In addition, it is difficult for one undiluted solution to move through the partition wall 15 through the other undiluted solution, and it can be stored stably. At this time, the discharge container 10 has the pistons 22 and 23 formed integrally. Therefore, both pistons 22 and 23 can be moved at the same distance at the same time, and the discharge rate ratio is always constant. Even if only one of the aerosol valves 13 is opened, both the pistons 22 and 23 of the pressurizing member 12 are integrated, so that the stock solution is not discharged.

  Both pistons 22 and 23 receive the same pressure from the pressurizing chamber S3, but if there is a difference in viscosity between the first stock solution A and the second stock solution B in both stock solution storage portions S1 and S2, the connecting portion of the pressurizing member 12 24 may be bent or deformed, and the vertical positions of both pistons 22 and 23 may be shifted, or both pistons 22 and 23 may be tilted. In the case of a discharge container in which the piston is operated by hand as in Patent Documents 1 and 2, the user can perform an operation (operation to increase or decrease the force applied to the left and right pistons) so that both pistons move in the same manner. However, the discharge container 10 not only integrates both pistons 22 and 23 but also the discharge container 10 has a dip tube 31 (guide rod) extending vertically in the inside thereof, and both pistons 22 and 23 are the dip tubes. Since it has the support cylinder 25 which slides 31 (guide rod), the independent movement of both pistons 22 and 23 of the pressurization member 12 is controlled, both pistons 22 and 23 shift | deviate up and down, both pistons The tilting of the 22 and 23 is prevented. Therefore, the discharge amounts of both stock solutions can be matched. When there is a difference in viscosity of the stock solution in this way, the pressure member 12 moves up and down according to the piston having a large resistance.

As for each valve connection part 115b, 116b, connection base part 115c, 116c is each inserted in the mounting part 114a of the valve holder mentioned later, and connection front-end | tip part 115d, 116d is inserted in the tube connection part 26f of the aerosol valve 113. However, the valve connecting portion may be connected only to either the tube connecting portion of the aerosol valve or the mounting portion of the valve holder.

The main body 116a of the second cylinder has the same vertical position as the main body 115a of the first cylinder, and has the same height as the main body 115a. On the other hand, the cross-sectional area is made smaller than that of the main body 115a. That is, the inner diameter is small. Therefore, the discharge amount is in accordance with the ratio of the respective cross-sectional areas. However, they may have the same diameter so as to have the same discharge amount.
Moreover, although each main body is made into cylindrical shape, if it is cylindrical, it will not specifically limit. For example, it may be a polygonal cylinder such as a triangular cylinder or a square cylinder, or may be another shape such as a semicircle.

As shown in FIGS. 13A and 13B, the pressurizing member 112 includes a disk-shaped first piston 121 that pressurizes the inside of the first cylinder 115 (first stock solution storage part S1), and the inside of the second cylinder 116 (first 2 has a disk-like second piston 122 for pressurizing the stock solution storage part S2) and a connecting part 123 for connecting them.
The first piston 121 and the second piston 122 slide with the inner surface of the main body 115a of the first cylinder 115 and the inner surface of the main body 116a of the second cylinder 116, respectively, while maintaining sealing properties.
The connecting portion 123 includes a first leg portion 123a extending from the lower surface of the first piston 121, a second leg portion 123b extending from the lower surface of the second piston 122, and a connecting plate 123c that connects them. The first leg 123a and the second leg 123b have the same height. Therefore, the first piston 121 and the second piston 122 are configured to abut simultaneously with the upper surfaces of the cylinders (stock solution storage portions S1, S2), respectively.
The pressure member 112 moves up and down according to the viscosity of the stock solution and the greater resistance force of the first piston or the second piston caused by the cross-sectional area of the cylinder (stock solution storage unit).

The valve holder 114 has two cylindrical mounting portions 114 a extending from the lower end of the valve holding portion 21. The other configuration is substantially the same as that of the valve holder 43 of the discharge container 40 of FIG. 4, and includes a support step portion 21a, a rising wall 21b, and an annular groove 21c.
In the discharge container 110, a valve assembly is constituted by two aerosol valves 113, a valve holder 114, and a lid 45 d of the pressure-resistant container 111 in which a holder holding part 47 that holds the valve holder 114 is formed.

  The method for filling the discharge container 110 with the stock solution and the pressurizing agent is as follows. The container member 48a is formed from a metal plate such as aluminum by drawing and ironing. On the other hand, the aerosol valve 113 is held by the valve holder 114, and the valve holder 114 is attached to the lid member 48b. Separately, the first cylinder 115 and the second cylinder 116 of the cylinder assembly 120 which are set by attaching the pressure member 112 are attached to the valve holder mounting portion 114a. That is, the pressure member 112, the aerosol valve 113, the valve holder 114, the cylinder assembly 120, and the lid member 48b are integrated. The integrated lid member 48b is placed on the container member 48a. Then, the pressurizing agent P is filled between the lid member 48b and the container member 48a, and at the same time, the container member 48a and the lid member 48b are fixed by double winding. Thereafter, by operating the stem 27 of each aerosol valve 113, the air remaining in the space of the first cylinder 115 (first stock solution storage unit S1) and the space of the second cylinder 116 (second stock solution storage unit S2) is removed. Discharge. That is, the first piston 121 and the second piston 122 are raised to the upper end. Finally, the first stock solution A and the second stock solution B are filled from each stem 27.

  The discharge container 110 also has the same amount of movement when the aerosol valve 113 is opened because both the pistons 121 and 122 of the pressurizing member 112 receive the same pressure and are integrated with each other. Further, in the discharge container 110, the first cylinder 115 and the second cylinder 116 have different volumes, and can discharge stably in accordance with the volume ratio. The first cylinder 115 and the second cylinder 116 may have the same volume. These volume ratios can be appropriately selected depending on the type of stock solution and the method of use. Further, the discharge container 110 is provided with a cylindrical cylinder (stock solution storage part) in the pressure-resistant container 111, and the stock solution storage part is independent of the pressure-resistant container. By simply attaching to the valve assembly, the discharge amount (volume) of each stock solution can be easily adjusted.

  The discharge container 110a of FIG. 14 has a plurality of guide legs 125 in which the connecting plate 123c of the connecting portion 123 of the pressurizing member 112 protrudes outward in the radial direction and the tips thereof abut against the inner surface of the pressure resistant container 111. In this embodiment, as shown in FIG. 14b, four guide legs 125 extend radially at equal intervals. The tip 125a of the guide leg 125 has an arcuate cross section so as to slide stably with the inner surface of the pressure vessel 111. By providing the guide legs 125 in this way, even if the resistance received by the first piston and the second piston is greatly different, such as a large difference in viscosity between the first and second stock solutions, the first piston 121 and the second piston 122 are provided. Can be prevented from being displaced or the pressure member 112 from being inclined. Further, in the discharge container 110a, the connecting bridge 117 of the cylinder assembly 120 is also provided at the upper ends of the first cylinder 115 and the second cylinder 116, and the first cylinder 115 and the second cylinder 116 are larger than the discharge container 110 in FIG. It is firmly connected. This facilitates further handling during assembly. Further, since the outer peripheral portion of the lower end of the cylinder assembly 120 is in contact with the inner surface of the pressure resistant container 111 and is stably held, even if the discharge product 110a is accidentally dropped, the mounting portion of the valve connecting portion and the mounting portion 114a may be broken. There is no problem such as bending, and the pressure member can be moved more stably. Other configurations are substantially the same as those of the discharge container 110 of FIG.

15 is different from the discharge container 110 in FIG. 13 and the discharge container 110a in FIG. 14, the first cylinder 115 and the second cylinder 116 are independent. The first cylinder 115 includes a connecting bridge 117. Except for this point, it is substantially the same as the first cylinder 115 of the discharge container 110 of FIG.
The second cylinder 116 has a tapered shape in which the upper portion 116f is reduced in diameter upward, and the valve connecting portion 116b is configured to be mounted on the outer periphery of the mounting portion 114a of the valve holder. However, it is different from the second cylinder 116 of the discharge container 110 of FIG. Other configurations are the same as those of the discharge container 110 of FIG.
In this embodiment, the first cylinder 115 is made of synthetic resin, and the second cylinder 116 is made of metal (aluminum, aluminum alloy, tinplate, stainless steel, etc.). Thus, by making the first cylinder 115 and the second cylinder 116 separate, the material can be appropriately selected according to the contents filled in the respective cylinders, and stable long-term storage can be achieved. It becomes possible. In particular, it is preferable to use a metal because the permeation of components and pressure agent in the stock solution can be prevented.

The pressurizing member 112 of the discharge container 110b is different from the second piston 122 of the discharge container 110 of FIG. 13 in the shape of the upper surface (pressing portion) 122a of the second piston 122. In other words, the second cylinder 116 is formed in a mountain shape so as to be in close contact with the inner surface of the upper part 116f. Further, the guide leg 125 of the pressure member 112 has a ring shape. Other configurations are substantially the same as those of the discharge container 110a of FIG.
Alternatively, the connecting plate 123c may be formed in a disc shape, and a ring-shaped guide leg 125 may be slid on the outer periphery of the connecting plate 123c with the inner surface of the pressure vessel 111. In particular, the pressure-resistant container 111 can be partitioned into a stock solution chamber and a pressure chamber by bringing the guide leg 125 and the inner surface of the pressure-resistant container 111 into contact with each other with a sealing property. In that case, the 1st cylinder and the 2nd cylinder serve as the partition part of the 1st mode of the present invention.
