That is, by pushing down the stem 14a of the valve mechanism 14, the stem rubber 14b is bent, the inside of the housing 26 communicates with the outside, and the stock solution passage A1 is opened. Therefore, the stock solution C pressurized by the pressurizing agent P in the inner container (gas storage part PS) is discharged to the outside from the stem 14a through the stock solution passage A1.

Next, an example of a method for filling the discharge container 10 with a stock solution and a pressurizing agent (a method for manufacturing a discharge product) will be described.
First, the outer preform for the container body and the inner preform for the inner container are individually molded by injection molding or the like, and the inner preform is inserted into the outer preform to prepare a two-layer preform. The container body 11 and the inner container 12 are simultaneously formed from the preform by biaxial stretching blow or the like (see FIG. 2a). In addition, the container main body 11 and the inner container 12 may be formed separately and inserted into the container main body 11 while the inner container 12 is crushed.

  Next, as shown in FIG. 5a, the container body 11 is placed on the turntable 36a. On the other hand, a pressure agent filling machine 37 having a pressure agent filling nozzle 37 a is attached to the cap 16 of the valve assembly 13, and the valve assembly 13 is arranged above the container body 11. Then, the container body 11 is rotated with respect to the valve assembly 13 (pressurizing agent filling machine 37), and the screw of the cap 16 is tightened to hold the valve assembly 13 above the fixing position with the container body 11. That is, the cap 16 of the valve assembly 13 is not completely screwed with the container body 11 so that the second sealing material 19 and the third sealing material 20 do not have a sealing effect. At this time, the pressurizer filling machine 37 holds the cap 16 and is attached to the cap 16 so that the space S between the cap 16 and the pressurizer filling machine 37 is sealed so that the pressurizer P does not leak. It is done.

In this holding state, the pressure agent P is supplied to the space S from the pressure agent filling nozzle 37a. As a result, the pressure agent P is filled into the inner container 12 from between the valve cover 22 and the cap 16 through the pressure agent filling passage PP. Specifically, the pressurizing agent filling passage PP is formed between the tube portion 29 of the valve cover 22 and the upper tube portion 32 of the cap 16, and between the flange portion 30 of the valve cover 22 and the connecting portion (pressing portion) 33 of the cap 16. It reaches the outside of the support flange 27 of the valve holder 21 between the holding protrusions 34b, and between the support flange 27 of the valve holder 21 and the flange portion 12d of the inner container 12 (second seal material 19). At this time, the valve unit 15 is slightly lowered with respect to the cap 16 due to the filling pressure of the pressurizing agent, and is supported by the engaging protrusion 34 b of the cap 16. Therefore, a large gap can be secured between the upper surface of the flange portion 30 of the valve cover 22 and the lower surface of the connecting portion (pressing portion) 33 of the cap 16. Even when the filling pressure of the pressurizing agent P is applied to the valve unit 15, the opening of the container body 11 is not closed by the valve holder 21 or the like.
And since the 1st sealing material 18 has sealed between the lower part of the cap 16 and the container main body 11 at the time of filling with a pressurizing agent, the pressurizing agent P does not leak outside from the lower end of the cap 16.
Note that the entire cap 16 is covered with the pressurizing agent filling machine 37, and the entire cap 16 is accommodated in the sealed space S (for example, the lower end of the pressurizing agent filling machine 37 is the shoulder of the container body 11 as indicated by an imaginary line). 11b). In this case, the pressurizing agent P can be filled even in a state where the first sealing material 18 is omitted or in a state where the first sealing material 18 does not seal between the lower portion of the cap 16 and the container body 11.

After filling the pressurizing agent P, the container body 11 is further rotated to fix the valve assembly 13 to the container body 11. Thereby, the 2nd sealing material 19 and the 3rd sealing material 20 are compressed, and the inside of the inner container 12 is sealed.
When the supply of the pressurizing agent P from the pressurizing and filling nozzle 37a is stopped after filling the pressurizing agent P, the pressure in the inner container 12 and the space S is substantially balanced. Therefore, when the container main body 11 is rotated and the cap 16 is lowered with respect to the container main body 11, the valve unit 15 and the container main body 11 (inner container 12) are integrated by the third sealing material 20, and the valve unit 15 Slides against the cap 16. Thereby, the position of the horizontal passage groove 27a of the valve unit 15 and the vertical passage groove 12g between the container main body 11 and the inner container 12 is difficult to shift. Further, it is possible to prevent the second sealing material 19 between the container body 11 and the valve unit 15 from being displaced, twisted or cut.
Note that the flange portion 12d of the inner container 12 may be compressed without using the second seal material 19, and the flange portion 12d may be used instead of the seal material.

Thereafter, the stem 14a is pushed down to discharge a small amount of the pressure agent P and air that have entered the stock solution storage part S1 (the space between the container body 11 and the inner container 12).
Finally, the stock solution C is filled from the stem 14a into the stock solution container S1 while the inner container 12 is contracted, and the discharge product of FIG. 1 is obtained.
Here, the container body 11 is rotated and screwed into the valve assembly 13, but the valve assembly 13 may be fixed by rotating the cap 16. However, since the valve assembly 13 is connected to the pressurizing agent filling machine 37, the apparatus is not complicated when the container body 11 is rotated.

As another example of a method for filling the discharge container 10 with a pressurizing agent (a method for manufacturing a discharge product), when the valve assembly 13 is held above a fixed position with the container body 11, as shown in FIG. The first seal member 18 is positioned below the lower end of the cap 16 so that a seal between the cap 16 and the container body 11 is not formed, and the pressure agent filling machine 37 and the shoulder portion of the container body 11 are configured. 11b may be sealed with a sealing material 37b, and the pressurizing agent P may be filled from the pressurizing agent filling nozzle 37a disposed in the vicinity of the lower end of the cap 16 via the pressurizing agent filling passage PP2. The pressurizing agent filling passage PP2 extends from between the container body 11 and the cap 16 to between the support flange 27 of the valve holder 21 and the flange portion 12d of the inner container 12 (second sealing material 19).
In the case of this filling method, the valve unit 15 (valve cover 22) is moved upward by the filling pressure of the pressurizing agent, and the flange portion 30 comes into contact with the inner surface of the connecting portion 32 of the cover cap 16. A pressurizing agent filling passage can be formed between the valve units 15, and the pressurizing agent can be stably filled. Therefore, the locking protrusion 29a of the cap 16 may be omitted. Even when the cap 16 is rotated to fix the container body 11, the valve unit 15 and the container body 11 (inner container 12) are integrated by the third sealing material 20. 16, the position of the lateral passage groove 27a of the valve unit 15 and the longitudinal passage groove 12g between the container body 11 and the inner container 12 is difficult to shift, and the container body It is possible to prevent displacement, twisting and cutting of the second sealing material 19 between the valve 11 and the valve unit 15.
Also when this filling method is adopted, the cap 16 may be fixed and the container body 11 may be rotated to fix the cap 16 to the container body 11. Further, filling may be performed both from between the tube portion 29 of the valve cover 22 and the upper tube portion 32 of the cap 16 (filling from above) and from the lower end of the cap 16 (filling from below).

That is, when the stem 56 of the valve mechanism 51 is pushed down, the first stock solution C1 and the second stock solution C2 are discharged from the stem 56 through the first stock solution passage A1 and the second stock solution passage A2.

Next, a method for filling the discharge container 40 with a stock solution and a pressurizing agent (a method for manufacturing a discharge product) will be described.
First, the container body 41 and the inner container 12 are formed in the same manner as the discharge container 10 of FIG.
Next, the innermost container 42 filled with the second stock solution C2 is connected to the innermost container connection portion 61f of the housing 61 of the valve assembly 43. The cap 46 of the valve assembly 43 to which the innermost container 42 is connected is attached to a pressurizing agent filling machine 37 (see FIG. 8b) having a pressurizing agent filling nozzle 37a, and the valve assembly 43 is disposed above the container main body 41.

In this holding state, the pressurizing agent P is filled from between the valve cover 16 and the cap 46 (pressurizing agent filling passage PP) as in the discharge container 10 of FIG. At this time, since the first sealing material 18 seals between the lower portion of the cap 46 and the container main body 41, the pressurizing agent P does not leak from the lower end of the cap 46 to the outside. Since the valve unit 45 is held by the support protrusion 34b, the pressure agent filling passage PP is secured without the valve unit 45 closing the opening of the container body 41 even when the pressure of the pressure agent P is applied. Is done.

After filling the pressurizing agent P, the valve assembly 43 is further lowered. That is, the second annular protrusion 46a of the valve assembly 43 is moved over the first annular protrusion 41a of the container body 41, and the upper surface 46c of the second annular protrusion 46a and the lower surface 41c of the first annular protrusion 41a are engaged and fixed. (See FIG. 6).
After fixing the container body 41 and the valve assembly 43, the inside of the first stock solution storage part S1 is deaerated, and the first stock solution C1 is filled from the stem 56 through the first stock solution passage A1. The empty innermost container 42 is connected to the valve assembly 43, and after filling the pressurizing agent between the inner container 12 and the innermost container 42 (gas storage part), the first stock solution and The second stock solution may be filled separately.
In addition, this discharge container 40 is also filled with other pressurizing agents so that the first sealing material 18 does not form a seal in the holding state as in the discharge container 10 of FIG. The pressurizing agent P may be filled from the lower end of the cap 46.

The discharge container 65 of FIG. 9 does not include an internal container, and is a mixture of the stock solution C and the pressurizing agent P in the container body.

Absent. Other configurations are substantially the same as those of the discharge container 10 of FIG.
The discharge container 65 becomes a discharge product by filling the container body 11 with the stock solution and the pressure agent P.

The undiluted solution passage of the discharge container 65 is formed from the second lateral passage groove 66 to the outside of the support flange 27, between the support flange (first flange portion) 27 and the flange portion (second flange portion) 30 (lateral passage groove 27a), The gap 25 between the housing 26 and the valve cover 22, the first communication hole 26a, the inside of the housing 26, and the stem 14a are reached. The discharge container 65 may discharge the stock solution with the pressure of the pressurizing agent, or may mix and discharge the stock solution and the pressurizing agent P at the same time.
In the method for filling the stock solution and the pressure agent in the discharge container 65, the valve assembly 13 in which the stock solution is filled in the container body 11 and the pressure filling machine 37 as shown in FIG. Hold. In this holding state, the pressure agent P is supplied from the pressure filling nozzle 37a. Thereby, the pressurizing agent P is filled into the container main body 11 from between the valve cover 22 and the cap 16 through the same pressurizing agent filling passage PP as the discharge container 10 of FIG. As another filling method, similarly to the discharge container 10 of FIG. 1, as shown in FIG. 5 b, the first sealing material 18 is configured not to form a seal when in the holding state, so The pressurizing agent P may be filled. Further, the pressurizing agent P may be filled from the stem 14a after the discharge container 65 is assembled.

Next, a discharge container having another structure that can be used in the method for manufacturing a discharge product of the present invention will be described.
The discharge container 70 of FIG. 10 is of a type in which a stock solution is housed in an internal container (stock solution housing part S1), and a space (gas housing part PS) between the container body and the internal container is filled with a pressurizing agent. is there.

Between the container main body 11 and the cap 76 of the valve assembly 72, a first seal 18 material that is compressed in a radial direction (perpendicular to the axis of the container main body 11) is provided.
Between the container main body 11 and the inner container 71 and the valve unit 75 of the valve assembly 72, a second seal member 19 that is compressed in the vertical direction (the axis of the container main body) is provided.
The first sealing material 18 and the second sealing material 19 are substantially the same as the first sealing material 18 and the second sealing material 19 of the discharge container 10 of FIG.
In addition, you may provide the 3rd sealing material 20 similarly to the discharge container 10 of FIG.

  The inner container 71 is a cylindrical container having flexibility. Unlike the inner container 12 of the discharge container 10 of FIG. 1, it does not have a vertical passage groove. Further, the outer shape of the inner container 71 does not have to be the same shape as the inner surface of the container body.

  As shown in FIG. 10 b, the valve unit 75 of the valve assembly 72 is provided in the valve mechanism 14, a housing 78 that houses the valve mechanism 14, and an upper end opening thereof, and fixes the valve mechanism 14 to the housing 78. And a valve cover 79 provided with a flange portion 81a. The valve mechanism 14 is substantially the same as the valve mechanism 14 of the discharge container 10 of FIG.

As shown in FIG. 10 c, a communication hole 78 a that guides the stock solution C into the housing 78 is formed at the center of the bottom of the housing 78. A rubber support portion 78b for supporting the stem rubber 14b is formed at the upper end of the housing 78. The upper portion 78c of the housing 78 has an enlarged diameter.
As shown in FIG. 10 d, the valve cover 79 is formed at the canopy portion 81 that closes the opening of the housing 78, the rising cylinder portion 82 that extends upward from the inner edge of the canopy portion 81, and the center of the bottom surface of the canopy portion 81. And a cylindrical housing holding portion 83 and an inner cylindrical portion 84 provided outside the housing holding portion 83. An outer end portion (flange portion) 81 a of the canopy portion 81 is disposed at the upper end of the container body 11.
The rising cylinder portion 82 passes the stem 14 a of the valve mechanism 14.
The housing holding portion 83 includes an engaging claw 83 a that engages with the upper portion 78 c of the housing 78. This engagement claw 83a integrates the valve unit.
The inner cylinder portion 84 is designed so as to be fitted in a seal with the opening of the inner container 61.

  Returning to FIG. 10 b, the cap 76 is different from the cap 17 of the discharge container 10 of FIG. 1 in that the holding projection 76 a engages with the outer end 81 a of the canopy 81 of the valve cover 79. The other configuration is substantially the same as the cap 16 of the discharge container 10 of FIG. 1, and has an upper cylinder part, a pressing part, and a lower cylinder part, and a female screw and an inner cylinder part are formed on the inner surface of the lower cylinder part. The gap with the valve cover 79 is open upward.

  11A, the stock solution passage A1 of the valve assembly 72 extends from the communication hole 78a communicating with the stock solution storage portion S1 to the inside of the housing 78 and the stem 14a. That is, by depressing the stem 14a of the valve mechanism 14, the stock solution C is discharged from the stem 14a to the outside through the stock solution passage A1.

  As shown in FIG. 11b, the method for filling the discharge container 70 with the stock solution and the pressurizing agent (the production method of the discharge product) is performed by filling the stock solution C into the inner container 71 (stock solution storage part S1). The inner container 71 filled with is fitted to the inner cylindrical portion 84 of the valve cover 79. That is, the inner container 71 is sealed with the valve cover 79. The pressure filling machine 37 is attached to the cap 76 of the valve assembly 72, and the valve assembly 72 is held above the fixed position with the container body 11 (see FIG. 10b). At this time, the lower end of the inner container 71 is preferably in contact with the inner bottom of the container body 11, and the inner container 71 itself is preferably supported by the inner bottom of the container body 11. In this holding state, the pressure agent P is supplied from the pressure filling nozzle 37a. As a result, the pressurizing agent P is filled in the space (gas storage part PS) between the container main body 11 and the inner container 71 through the pressurizing agent filling passage PP between the valve cover 79 and the cap 76. Specifically, the pressurizing agent filling passage PP is formed between the rising cylinder portion 82 of the valve cover 79 and the upper cylinder portion 32 of the cap 76 and the connecting portion (pressing portion) 33 of the canopy portion 81 of the valve cover 79 and the cap 76. Until the space between the canopy 81 of the valve cover 79 and the upper end of the container body 11 (second sealing material 19). At this time, since the first sealing material 18 seals between the lower part of the cap 76 and the container body 11, the pressurizing agent P does not leak from the lower end of the cap 76 to the outside. Further, in this embodiment, since the inner container 71 and the inner cylinder portion 84 of the valve assembly 72 are seal-fitted, the pressurizing agent P is not introduced into the inner container 71. Since the valve assembly 72 is integrated, the pressure agent filling passage PP is secured without the valve unit 75 closing the opening of the container body 11 even when the filling pressure of the pressure agent P is applied. .

After filling the pressurizing agent P, the container body 11 or the cap 76 is rotated to fix the valve assembly 72 to the container body 11.
The inner container 71 and the inner cylinder portion 84 of the valve assembly 72 are not sealed and fixed, and then the stem 14a is pushed down to discharge the pressure agent P that has entered the inner container 71 (stock solution storage portion S1). Then, the stock solution C may be filled again by pushing down the stem 14a again. Moreover, you may provide the 2nd sealing material 19 between the flange part 71a of the internal container 71, and the upper end of the container main body 11 like FIG.
