Description

  The present invention relates to a discharge container in which a plurality of pouches are accommodated in an outer container.

  Patent Document 1 discloses a double aerosol container including two inner containers (pouches), an outer container that accommodates these inner containers, and a valve assembly that closes an opening of the outer container. In this double aerosol container, each pouch is filled with a stock solution and a pressurizing agent is filled between the external container and the pouch, so that the pouch is compressed by the pressure of the pressurizing agent, and the stock solution (contents) The product can be discharged to the outside.

  By the way, in the above-mentioned double aerosol container, when filling the pressurizing agent, the valve assembly is slightly lifted from the opening of the external container, and so-called under cup filling is performed in which the pressurizing agent is filled from the gap generated thereby. Adopted. Further, in order to float the valve assembly, a vertically long pouch is used, and the lower end of the pouch is brought into contact with the inner bottom of the outer container to lift the valve assembly. Such a configuration eliminates the need for a device for floating the valve assembly, and is advantageous in that work efficiency and cost reduction can be achieved.

JP 2013-147293 A Japanese Patent Laying-Open No. 2015-058980

  However, it can create new problems. In other words, after the pressurizing agent is filled, in order to keep the pressurizing agent between the outer container and the pouch, it is necessary to quickly push down the valve assembly so that it is closely attached and fixed to the outer container. It may be bent irregularly as if it is crushed.

  If the pouch is bent irregularly, it may be difficult to fill the pouch with the stock solution and the predetermined amount may not be filled. Even if it can be filled, there may be a case where the stock solution remains in the bent portion and cannot be discharged as intended. For this reason, the discharge amount varies from pouch to pouch.

  For example, as in Patent Document 2, if a rod-shaped flow path member is inserted into the pouch, the bending can be somewhat suppressed. However, in order to prevent the pouch from being pierced by the flow channel member, a short flow channel member is often used. In this case, it is impossible to suppress the bending at the lower part of the pouch, so it is not necessarily an effective means. There wasn't.

  Then, this invention aims at provision of the discharge container which can suppress the filling defect and discharge failure of stock solution.

  The discharge container of the present invention includes an outer container 10 having an opening (mouth portion 10f) at the top, a plurality of pouches 20A (70A) and 20B accommodated in the outer container 10, and the pouches 20A (70A) and 20B. A discharge container including a valve assembly 30 connected to the opening of the outer container 10 and having a lower end of the first pouch 20A (70A) positioned below the second pouch 20B, When the pouches 20A (70A) and 20B are accommodated in the outer container 10 in a state where the pouches 20A (70A) and 20B are connected to the valve assembly 30, the valve assembly abuts against the inner bottom of the outer container 10. 30 is supported so that it may become above the position when attached to the outer container 10.

  Moreover, it is preferable that the 1st pouch 20A (70A) is a pouch which consists of a synthetic resin layer, and the 2nd pouch 20B is a pouch which has a metal layer. Further, the vertical lengths of the first pouch 20A (70A) and the second pouch 20B are equal in the stock solution storage chamber 21d, and the first pouch 20A (70A) is preferably longer in the lower laminating portion 21c. Also, the first pouch 20A (70A) and the second pouch 20B are outer containers that are folded or rolled in the width direction so as to cover the outside of the second pouch 20B by the first pouch 20A (70A). It is preferable to be accommodated in 10.

  Moreover, it is preferable that 70 A of 1st pouches have the collar parts 74 and 75 in a side part. In this case, it is preferable that the collar parts 74 and 75 consist of a sheet | seat folded in V shape toward the center side of a pouch. Moreover, it is preferable that the lower end vicinity of the 1st pouch 70A is notched diagonally.

  In the discharge container of the present invention, the lower end of the first pouch is positioned below the second pouch, and the valve assembly is supported by the first pouch. Therefore, the second pouch is bent when the valve assembly is attached to the outer container. Can be suppressed. For this reason, at least the second pouch does not cause unsatisfactory filling of the stock solution due to bending, and no discharge failure occurs.

  In addition, if the first pouch is made of a synthetic resin layer, it is difficult to fold, and even if it is bent, it is easy to return to its original shape (excellent in restoration), so there is no filling failure or ejection failure. Not likely to occur. In addition, a pouch having a metal layer is easy to be compromised (it is inferior in resilience), but by using a pouch having a metal layer as the second pouch that does not support the valve assembly, it is possible to prevent the occurrence of poor filling or ejection failure. Can be prevented.

  Furthermore, if the lengths of the stock solution storage chambers in the first pouch and the second pouch are aligned in the vertical direction, the discharge amounts from the respective pouches can be easily matched, and the two stock solutions can be discharged at a stable ratio until the end. it can.

  Further, when the first pouch is folded so as to be positioned outside the second pouch or accommodated in the outer container in a rolled state, the first pouch is more than the second pouch covered outside by the first pouch. Since it can move relatively freely, it can be relatively gentle even if it bends.

  Further, if the first pouch has a flange on the side, the strength of the first pouch against the axial compressive force increases, and the valve assembly can be stably supported. In particular, the valve assembly can be supported more stably if the collar portion is made of a sheet folded in a V shape toward the center side of the pouch. In addition, if the vicinity of the lower end of the first pouch is cut obliquely, the strength near the lower end can be made smaller than that of the other parts, and when attaching the valve assembly to the outer container, the other parts are preceded. The vicinity of the lower end can be deformed. Moreover, it becomes easy to insert the first pouch into the outer container.

Next, a discharge container (aerosol container) 1 according to the present invention will be described with reference to the drawings. First, the outline of the discharge container 1 of the present invention will be described. As shown in FIG. 1, an outer container 10 having an opening in the upper part, two pouches 20A and 20B accommodated in the outer container 10, and the respective pouches 20A. 20B and a valve assembly 30 attached to the outer container 10. Further, the lower end of the first pouch 20A is positioned below the second pouch 20B, and each pouch is accommodated in the outer container 10 in a state where the valve assembly 30 and each pouch are connected. In contact with the inner bottom of the outer container 10 (the inner surface of the bottom 10a), the valve assembly 30 is supported by the first pouch 20A and is configured to be above the position when attached to the outer container 10. (See FIG. 6a). Then, the first and second pouches 20A and 20B are filled with the stock solution C, respectively, and the space between the outer container 10 and the pouches 20A and 20B is filled with the pressure agent P, so that each stock solution C is filled. A dischargeable discharge product is manufactured.
Hereinafter, each component will be specifically described.

  First, the outer container 10 will be described. As shown in FIG. 1, the outer container 10 has a cylindrical body part 10b whose lower end is closed by a bottom part 10a, and a diameter decreasing from the upper end of the body part 10b upward. A dome-shaped shoulder portion 10c provided in the above manner, a cylindrical neck portion 10d provided at the upper end of the shoulder portion 10c, a bead portion 10e formed in an annular shape at the upper end of the neck portion 10d, and an inner periphery of the bead portion 10e 10 f opening to the side.

  The outer container 10 is formed, for example, by forming a metal disk such as aluminum into a bottomed cylindrical shape by impact processing and squeezing and ironing, or forming a metal cup into a bottomed cylindrical shape by squeezing and ironing, and a synthetic resin coat is formed on the inner surface. Next, necking processing is performed on the upper end of the body portion 10b to form a shoulder portion 10c and a neck portion 10d, and curling processing is performed on the upper end portion of the neck portion 10d to form a bead portion 10e.

  The first pouch 20A and the second pouch 20B are accommodated in the outer container 10, respectively. These pouches are formed by stacking a plurality of flexible sheets, or by folding a single sheet, and then laminating the peripheral edges by heat welding or an adhesive (bag-making process). 21 and a flow path member 22 that is integrated with the bag body 21 and supplies the stock solution C in the bag body 21 to the valve 40.

  As shown in FIG. 2, the bag body 21 has a substantially rectangular shape, and is formed with bonding portions 21 a, 21 b, and 21 c at the upper portion, both side portions, and the lower portion, respectively. And the rectangular part enclosed by these bonding parts 21a, 21b, 21c becomes the stock solution storage chamber 21d for filling with the stock solution C. The lower laminating portion 21c is wider (longer in the vertical direction) than the upper laminating portion 21a. Two arc-shaped notches 21e are provided at the lower end of the lower bonding portion 21c. The width of the bag body 21 is larger than the opening diameter of the mouth portion 10f of the outer container 10 and larger than the inner diameter of the trunk portion 10b. Note that both ends of the lower laminating portion 21c are obliquely cut out (notched portion 21f) for facilitating the insertion of the inner container into the outer container 10. Therefore, it is not always necessary to provide the rectangular bag body 21.

  By the way, when comparing the first pouch 20A and the second pouch 20B, the bag body 21 of the first pouch 20A is longer in the vertical direction than the bag body 21 of the second pouch 20B. Specifically, the length of the stock solution storage chamber 21d is made equal in the vertical direction, but the length of the lower bonding portion 21c in the vertical direction is longer in the first pouch 20A, which is the first as a whole. The length of the pouch 20A is longer. Accordingly, when the heights of the upper ends of the first pouch 20A and the second pouch 20B are aligned, the lower end of the first pouch 20A is positioned below the second pouch 20B. The length in the width direction is the same for the first pouch 20A and the second pouch 20B, and the capacity of the stock solution storage chamber 21d is the same for the first pouch 20A and the second pouch 20B. However, it is not always necessary to have the same width, and the width may be varied depending on the ejection ratio.

  The sheet constituting the bag body 21 is determined by the stock solution C accommodated therein. For example, synthetic resin sheets such as polyethylene, polypropylene, polyethylene terephthalate, nylon, and eval, and vapor deposition in which silica, alumina, or the like is vapor-deposited on a synthetic resin sheet. Examples thereof include a resin sheet, a metal foil sheet such as aluminum or a synthetic resin sheet, a vapor-deposited resin sheet, and a laminated sheet obtained by laminating at least two sheets selected from metal foil sheets (particularly, a laminated sheet having a metal layer). In this embodiment, since the two-component reactive preparation is filled as the stock solution C, a configuration suitable for each stock solution C can be selected. For example, when a two-component hair dye is used as a two-component reaction-type preparation, the bag body 21 filled with the first agent containing an oxidation dye that exhibits a hair dyeing effect when oxidized has an oxygen barrier property. A bag body 21 made of an opaque laminated sheet obtained by laminating both sides of a metal foil sheet having a high chemical resistance with a synthetic resin sheet having a high chemical resistance, and filled with a second agent containing an oxidizing agent such as hydrogen peroxide. Consists of synthetic resin sheets with high chemical properties.

  In addition, the sheet | seat which has metal layers, such as metal foil, is easy to fold, and when it folds once, there exists a tendency which is hard to return to the original shape (it is inferior to recoverability). Therefore, the first pouch 20A that supports the valve assembly 30 when filling the pressurizing agent is a pouch made of a synthetic resin layer that does not have a metal layer, and the second pouch 20B that does not support the valve assembly 30 has a metal layer. A pouch composed of a sheet is preferable.

  The flow path member 22 is an integrally molded product of synthetic resin such as polyethylene or polypropylene, and as shown in FIG. 3, a mounting portion 23 to be mounted on the valve 40 and a welded portion provided at a lower portion of the mounting portion 23. 24 and a rod-like flow path portion 25 extending from the welded portion 24 toward the bottom portion (downward) of the bag body 21.

  The mounting portion 23 is formed in a cylindrical shape, and an engagement claw 23a that engages with an engagement projection 53d of a valve holder 50 described later is provided on the upper end thereof (see FIG. 4).

  The welding part 24 is a part for fixing the bag body 21 to the flow path member 22 by heat welding or ultrasonic welding (see FIG. 4). Its shape is a substantially rhomboid columnar section, and is flat along the surface of the sheet. Further, in order to make the bag body 21 firmly fixed, a plurality of horizontal ribs 24a extending in the horizontal direction are formed on the side surfaces thereof. The inside is hollow and communicates with the mounting portion 23. The welded portion 24 is provided so as to have the same height as the shoulder portion 10 c of the outer container 10 in a state where the valve assembly 30 is fixed to the outer container 10.

  The flow path portion 25 is provided at the upper end of the main body 26, a rod-shaped main body 26 extending in the vertical direction, a protrusion 27 that protrudes from the surface of the main body 26 and forms a flow path of the stock solution C on the surface of the main body 26. The stock solution C in the bag body 21 is led out into the housing 41 of the valve 40 in a state where the passage communicates with the inside of the welded portion 24 and the mounting portion 23 and the flow path member 22 is connected to the connecting cylinder 41 a of the valve 40. A lead-out hole 28 is provided.

  The protrusion 27 includes a plurality of main protrusions 27a provided at regular intervals in the vertical direction along the central axis of the main body 26, and the main protrusions 27a and the left and right directions on both sides of the main protrusion 27a. And a plurality of sub-projections 27b provided at regular intervals in the vertical direction. Furthermore, the sub protrusion 27b protrudes also in the left-right direction. The main ridge 27a and the sub ridge 27b are provided so as to be shifted in the vertical direction so that the sub ridge 27b is positioned between the main ridges 27a. Further, a trough 29 is formed between the main protrusion 27a and the sub-protrusion 27b in the vertical direction, and this trough 29 forms a flow path for the stock solution C. The upper end of the flow path is connected to a lead-out hole 28 provided so as to penetrate across the front and back of the main body 26 so that the stock solution C flowing through the flow path can be guided to the lead-out hole 28.

  Next, the valve assembly 30 will be described. As shown in FIG. 1 b, the valve assembly 30 covers two independent pouch valves 40, a valve holder 50 that receives the valves 40, the valve 40 and the valve holder 50, and puts the valve holder 50 into the outer container 10. The mountain cover 60 is fixed.

  The valve 40 is for filling the pouch with the stock solution C and selectively discharging / blocking the stock solution C filled in the pouch to the outside. Specifically, as shown in FIG. 4, the valve 40 includes a cylindrical housing 41, a stem 42 that is inserted into the housing 41 so as to freely move up and down, and a stem hole provided on a side surface of the stem 42. The stem rubber 43 includes a stem rubber 43 that covers the stem 42 a, a spring 44 that constantly biases the stem 42 upward, and a cover 45 that fixes the stem 42 and the stem rubber 43 to the housing 41.

  The housing 41 is a bottomed cylindrical body having a columnar space for inserting the stem 42. A cylindrical connecting tube 41a extends downward from the bottom, and the mounting portion 23 of the flow path member 22 of the inner container is connected (externally fitted) to the connecting tube 41a. Further, in order to communicate with the outlet hole 28 of the flow path member 22, a communication hole 41 b is provided at the bottom. An annular recess 41c is formed on the side surface, and a gasket (O-ring) 41d is provided in the annular recess 41c. The gasket 41 d is in contact with the valve holder 50 and seals between the housing 41 and the valve holder 50.

  The stem 42 has a bottomed cylindrical shape, and a stem hole 42a is formed on the side surface. And the stem rubber 43 is contacting so that this stem hole 42a may be plugged up.

  The stem rubber 43 has a ring shape, and its inner peripheral surface abuts against the side surface of the stem 42 to close the stem hole 42 a, and the outer peripheral side is fixed between the upper end of the housing 41 and the cover 45.

  The spring 44 is, for example, a metal helical spring, and is interposed between the lower end of the stem 42 and the housing 41 to urge the stem 42 upward.

  The cover 45 has a cup shape having an upper base 45a, and an insertion hole 45b through which the stem 42 is passed is formed in the upper base 45a. The cover 45 presses the stem 42 and the stem rubber 43 downward by the upper bottom 45a, and holds the stem 42 and the stem rubber 43 so as not to jump out by the bias of the spring 44. The cover 45 is fixed to the housing 41 by caulking the side surface of the cover 45 toward the housing 41 side in several places or around the entire circumference.

  The valve 40 configured as described above has a mechanism in which the inner periphery side of the stem rubber 43 is deflected by pushing down the stem 42 and the stem hole 42a is opened so that the outside communicates with the inside of the pouch. However, the valve 40 is not limited to this, and various known valves may be used.

  The valve holder 50 that holds the valve 40 includes a plug portion 51 that is inserted into the neck portion 10d from the mouth portion 10f of the outer container 10, and a bead portion of the outer container 10 that extends from the upper end of the plug portion 51 toward the side. 10e is comprised from the flange part 52 mounted in the upper end, and the cover part 53 which protrudes upwards from the flange part 52. As shown in FIG.

  The stopper 51 is cylindrical and has substantially the same diameter as the inner periphery of the neck 10 d of the outer container 10. An annular recess 51a is provided on the outer peripheral surface, and a gasket (O-ring) 51b is provided in the annular recess 51a. The gasket 51b contacts the inner peripheral surface of the neck 10d of the outer container 10 and is compressed in the radial direction, thereby forming a seal between the valve holder 50 and the outer container 10.

  The lid portion 53 rises upward in the vicinity of the periphery thereof, and forms the outer shape of the valve assembly 30. The rising wall 53a has a shape in which a part of a circle is cut out in plan view. This is a device that makes it possible to easily adjust the direction (position) of the valve assembly 30 and the discharge container 1 and confirm the direction by making the shape not point-symmetric. It is used when filling the inner container or when mounting the discharge member on the two stems 42. A cylindrical body (upper cylinder portion) 53b that rises upward is separately provided inside the rising wall 53a. Furthermore, a lower cylinder part 53c having a smaller diameter than the upper cylinder part 53b extends downward from the lower end of the upper cylinder part 53b. And the valve | bulb 40 is hold | maintained by the upper cylinder part 53b and the lower cylinder part 53c. That is, the upper cylinder part 53b and the lower cylinder part 53c form a holder part. An engagement protrusion 53d is provided on the inner peripheral side at the lower end of the lower cylinder portion 53c, and is engaged with the engagement claw 23a of the flow path member 22 of the inner container.

  As shown in FIGS. 4 and 5, the mountain cover 60 has a cylindrical cover portion 61 that covers the valve 40 and the valve holder 50, and a cylindrical shape having a larger diameter than the cover portion 61, and a flange portion of the valve holder 50. 52 and a fixing portion 62 for fixing the outer container 10 to each other.

  The cover portion 61 is formed with two openings 61a through which the stem 42 of the valve 40 is passed. Moreover, the cover part 61 is provided with a recessed part 61b that protrudes downward, and the cover 45 of the valve 40 is pressed downward by the recessed part 61b. By pressing in this way, the gasket 41d of the housing 41 is appropriately compressed and the sealing performance is improved. Further, by forming the recessed portion 61b, the rigidity of the mountain cover 60 is increased, and even if the pressure of the pressurizing agent is continued, the deformation is suppressed and the valve 40 is held at a predetermined position and the sealing performance is maintained for a long time. be able to.

  The fixing portion 62 has an upper flange portion 62a that contacts the upper surface of the flange portion 52 of the valve holder 50. When the valve assembly 30 is attached to the outer container 10, the lower flange portion 62b is formed by caulking the lower end. The

  A discharge product using the discharge container 1 having the above-described configuration is manufactured as follows. First, the valve 40 is inserted into the holder portion of the valve holder 50. Next, the pouch mounting portion 23 is engaged with the lower cylinder portion 53 c of the valve holder 50. As a result, the connecting cylinder 41a of the housing 41 of the valve 40 is inserted into the mounting portion 23 of the flow path member 22, and the inside of the bag body 21 of the first and second pouches 20A and 20B and the inside of the housing 41 of the valve 40 are communicated. To do. In this state, the first pouch 20A and the second pouch 20B have the same height at the upper end, and the lower end of the first pouch 20A is positioned below the second pouch 20B.

  Next, the first pouch 20A and the second pouch 20B are inserted into the outer container 10, respectively. Since the width of the bag body 21 is larger than the diameter of the mouth portion 10f of the outer container 10, as shown in FIGS. 6a and 6b, the left and right ends of the bag body 21 are inserted in a folded state. At this time, the bag body 21 of the first pouch 20A made of a synthetic resin sheet is folded (or covered) so as to wrap (cover) the outside of the bag body 21 of the second pouch 20B made of a laminated sheet including a metal sheet. It is preferable to round the shape. By doing in this way, the synthetic resin sheet which is flexible and has low frictional resistance is positioned on the outside, and the insertion into the outer container 10 becomes smooth.

  When the first and second pouches 20A and 20B are inserted to some extent, the lower end of the first pouch 20A comes into contact with the inner bottom of the outer container 10, and the valve assembly 30 is supported by the first pouch 20A. (Ie, located above the position when attached to the outer container 10). At this time, the valve assembly is easily maintained horizontally by the first pouch 20A that is folded and inserted. In this state, the pressurizing agent P is filled between the outer container 10 and the pouch from the gap formed between the plug part 51 of the valve holder 50 and the mouth part 10f of the outer container 10 (so-called under cup). filling). At this stage, the bag body 21 maintains the folded state. As the pressurizing agent P, for example, a compressed gas such as nitrogen, compressed air, carbon dioxide, nitrous oxide is filled. The pressure after filling is, for example, 0.1 to 0.5 MPa (gauge pressure) at 25 ° C.

  After filling with the pressurizing agent, the valve assembly 30 is pushed down to press the flange portion 52 against the bead portion 10 e of the outer container 10. At this time, the first pouch 20 </ b> A is compressed and deformed in the vertical direction between the valve assembly 30 and the inner bottom of the outer container 10. In addition, since the flow path member 22 has very high rigidity compared to the bag body 21, the bag body 21 is mainly deformed. The deformation starts when the bag body 21 that has been folded or rounded is first unfolded to be generally arcuate in plan view (see FIGS. 6c and d). Subsequently, the vicinity of the lower portion of the bag body 21 is inclined so as to slide on the inner bottom of the outer container 10, and the push-in of the valve assembly 30 is allowed. At this time, since the bag body 21 has a circular arc shape in a plan view, the inclining direction is always on the inner side (center side) of the arc. Therefore, the bending method does not vary for each product, and it bends in a substantially fixed form. In addition, bending is mainly caused by the lower end of the bag body 21, that is, the lower laminating portion 21c, in which the arc shape is most likely to collapse and the rigidity is likely to be low. Not likely to occur. In addition, in order to further suppress the bending of the stock solution storage chamber 21d, it is preferable to make the length in the vertical direction of the lower bonding portion 21c longer than the pushing amount of the valve assembly 30.

  Further, since the second pouch 20B having a metal layer that is easy to fold does not support the valve assembly 30, the second pouch 20B is hardly affected by the pushing of the valve assembly 30. In particular, if the vertical difference e between the lower end of the first pouch 20A and the lower end of the second pouch 20B exceeds the push amount of the valve assembly 30, even if the valve assembly 30 is pushed, the second pouch 20B can be The second pouch 20B will not be bent. If the vertical difference e between the lower end of the first pouch 20A and the lower end of the second pouch 20B is less than the pushing amount of the valve assembly 30, the second pouch 20B comes into contact with the inner bottom of the outer container 10. Therefore, the second pouch 20B is also bent to some extent, but since the amount to be pushed in is smaller than that of the first pouch 20A, the degree of bending is small, and filling failure and discharge failure of the stock solution C are sufficiently suppressed. It will be. In the figure, 21 g is a bent line formed by the corner portion of the bag body 21 coming into contact with the inner surface of the shoulder portion 10 c of the outer container 10. Thus, if the corner is bent, it becomes difficult to fill the corner with the stock solution C, and the remaining of the stock solution C at the corner can be suppressed.

  Thereafter, the lower end of the mountain cover 60 previously placed on the valve holder 50 is crimped and fixed to the outer container 10. Thereby, the gasket 51b is compressed and sealed in the radial direction between the inner surface of the neck portion 10d of the outer container 10 and the annular recess 51a of the plug portion 51, and is shut off from the outside.

  And the air in the bag body 21 is discharged | emitted from the stem 42, and the stock solution C is suitably filled in the 1st, 2nd pouch 20A, 20B as shown to FIG. As the stock solution C, for example, a two-component reactive cream such as a two-component hair dye, a two-component perm agent, a two-component adhesive, a two-component warm shave, a two-component cold sensation cream or gel ( For example, the viscosity is 100 to 100,000 mPa · s), liquid, and the like. When the stock solution C is filled in the first and second pouches 20A and 20B, the bag body 21 expands and the lower end side is lifted upward. Therefore, even if the stock solution storage chamber 21d is bent, the bend is gradually eliminated, and a predetermined amount of the stock solution C can be filled. The pressure after filling the stock solution is, for example, 0.3 to 0.8 MPa (gauge pressure) at 25 ° C. Thus, the manufacture of the discharge product is completed.

  Next, another discharge container 1A will be described. The discharge container 1A shown in FIG. 7 is characterized in that a transparent container made of polyethylene terephthalate (PET) is used as the outer container 10A. Thus, if the outer container which has translucency is used, the state of the 1st, 2nd pouch 20A, 20B can be grasped | ascertained from the outside. Therefore, for example, it is possible to know how much stock solution C remains in the first and second pouches 20A and 20B, which is a guideline for replacement timing. Further, in this outer container 10A, in order to ensure pressure resistance, five leg portions 10h are provided in the circumferential direction at equal intervals in the circumferential direction (so-called petaloid), and overall, the trunk portion 10b. The diameter is reduced from the bottom portion 10a to the bottom portion 10a (see the reduced diameter portion 10i). Therefore, the first pouch 20 </ b> A can easily maintain a circular arc shape in plan view, and the folding direction of the bag body 21 due to the pushing of the valve assembly 30 is always stable.

  The material of the outer container 10A is not limited to PET, and various known synthetic resins such as nylon and polypropylene can be used. The synthetic resin outer container 10A is molded by, for example, biaxial stretch blow molding or injection molding. When the outer container 10A is made of a synthetic resin such as PET, a flange portion 10g is provided instead of the bead portion 10e. The valve assembly 30 is fixed to the flange portion 10g of the outer container 10A by caulking the lower end of the mountain cover 60. Since other configurations are the same as those in the above embodiment, the same reference numerals are given and description thereof is omitted.

  8 and 9 are drawings showing a pouch used in place of the first pouch 20A of the above embodiment. The first pouch 70 </ b> A includes a front surface portion 72 whose bag body 71 faces the front surface side of the outer container 10, a back surface portion 73 facing the center side, and the left and right sides of the front surface portion 72 and the back surface portion 73. It is comprised from the side collar parts 74 and 75 respectively interposed between edges. However, you may have a side collar part only in either one of right and left.

  As shown in FIG. 8, each of the front surface portion 72 and the back surface portion 73 has a substantially rectangular shape that is vertically long and has a cutout portion 76 formed by obliquely cutting out both left and right lower ends. However, different shapes may be adopted for the front surface portion 72 and the back surface portion 73. The side flanges 74 and 75 also have a notch 77 formed by obliquely notching the left and right lower ends. In addition, as a whole, the rectangular shape is thinner than the front surface portion 72 and the back surface portion 73. As shown by imaginary lines (one-dot chain lines), the side flanges 74 and 75 are surface portions in a state of being folded into a substantially V shape so that the central portion protrudes inward (toward the center side of the pouch). 72 and between the side edges of the back surface portion 73. However, it may be substantially W-shaped or bellows-shaped.

  Laminate portions 71a, 71b, 71c, and 71d are formed on the upper portion, both side portions, the notch portion, and the lower portion of each sheet constituting the front surface portion 72, the back surface portion 73, and the side flange portions 74 and 75, respectively. Actually, each bonded portion is formed after joining in combination. And the bonding parts of adjacent sheets are joined together by welding or the like. That is, the upper laminating portion 71a of the front surface portion 72 and the back surface portion 73 is bonded to each other while sandwiching the flow path member 22 in the vicinity of the center, and in the vicinity of the left and right ends, the side wall portion folded in a V shape. 74 and 75 are bonded to the upper bonding portions 71a and 71a. In this embodiment, the folded portions at the upper ends of the side flanges 74 and 75 (V-shaped inner surfaces) are not bonded together. As a result, the side flange portions 74 and 75 are easily expanded (expanded easily), and a side bonding portion 71b described later is not easily bent. However, they may be bonded together to facilitate the manufacture of the bag body 71.

  The side laminating portions 71b provided at the left and right side edges of the front surface portion 72 and the back surface portion 73 are respectively bonded to the front side and the back side side laminating portions 71b of the left and right side flange portions 74 and 75. It is matched. The diagonally bonded portion 71c of the cutout portion 76 of the front surface portion 72 and the back surface portion 73 is bonded to the diagonally bonded portion 71c of the front side of the left and right side flange portions 74 and 75 and the cutout portion 77 on the back surface side. A lower laminating portion 71d in the horizontal lower portion of the front surface portion 72 and the back surface portion 73 is bonded to the lower laminating portion 71d in the horizontal lower portion of the left and right side flange portions 74 and 75.

  Any of the above-mentioned laminating portions can be performed by aligning the respective edge portions in the outward direction, overlapping them, and joining them by heat welding. Depending on the material, they may be joined by ultrasonic welding, high-frequency welding or the like, or may be joined using an adhesive. In addition, instead of bonding the four sheets, for example, a sheet in which the front surface portion 72, the one side flange portion 74, and the back surface portion 73 are integrated, and a sheet constituting the other side flange portion 75. The bag body 71 may be formed by bonding, or the bag body 71 may be formed by previously forming a sheet in a cylindrical shape and bonding the upper and lower ends. The material of the sheet is the same as that of the first pouch 20A.

  In any of the bag bodies 71, a substantially rectangular parallelepiped portion surrounded by the pasting portions is a stock solution storage chamber 21d for filling the stock solution C. And since it has the side collar parts 74 and 75, in the state filled with the stock solution C, as shown in FIG. 9c, a horizontal cross section becomes a substantially rectangular shape. On the other hand, before filling with the stock solution C and after discharging, as shown in FIG. 9b, the side flanges 74 and 75 maintain a V shape in plan view, except for the portion where the flow path member 22 is interposed, The inner surfaces of the sheet of the front surface portion 72, the back surface portion 73, and the side flange portions 74 and 75 are in close contact with each other.

  When the first pouch 70A having the above-described configuration is inserted into the outer container 10 and the lower end thereof is brought into contact with the bottom 10a of the outer container 10, the lower ends of the side flanges 74 and 75 spreading in a V shape in plan view are the center of the pouch. Therefore, the valve assembly 30 can be stably supported even with a single pouch. Therefore, a gap can be reliably formed between the valve assembly 30 and the outer container 10, and the pressurizing agent P can be reliably filled.

  After the pressurizing agent is filled, the first pouch 70A is deformed by being compressed in the vertical direction as the valve assembly 30 is pushed down, but notches 76 and 77 are provided in the vicinity of the lower end, and the vicinity of the lower end is above it. Since the strength is lower than that of the portion, the vicinity of the lower end is deformed in advance. Therefore, the bending method does not vary from product to product, and the product is bent in a substantially fixed form, so that the filling failure and ejection failure of the stock solution C due to the bending are unlikely to occur.

  As shown in FIGS. 9b and 9c, the second pouch 70B may have a flange on the side as in the case of the first pouch 70A. In that case, by shortening the lower bonding portion 71d, The second pouch can be prevented from bending. However, it is good also as a pouch which does not have a collar part as shown in FIG.1 and FIG.2. About another structure, it is the same as that of the said embodiment.

  As mentioned above, although typical embodiment of this invention was described, this invention is not limited to the said embodiment, It can be implemented in various changes within the scope of this invention. For example, the number of pouches is not limited to two and may be three or more. If the structure which supports the valve assembly 30 with at least 1 pouch is taken, there exists an effect similar to the said embodiment. Moreover, in the said embodiment, the lower end of 1st pouch 20A, 70A is located below 2nd pouch 20B by making the length of the up-down direction of 1st pouch 20A, 70A longer than 2nd pouch 20B. However, the position of the first pouch 20A, 70A is made lower than the second pouch 20B by adjusting the attachment position to the flow path member 22 or adjusting the length of the flow path member 22. Thus, the lower ends of the first pouches 20A and 70A may be positioned below the second pouch 20B. In this case, there is an advantage that the same bag bodies 21 and 71 can be used. Further, the cutout portions 21e and 21f of the lower bonding portion 21c of the pouch, the cutout portions 76 of the front surface portion 72 and the back surface portion 73, and the cutout portions 77 of the side flange portions 74 and 75 are not necessarily provided.
