[Embodiment 1]

  1 to 6 show the first embodiment.

  In this pressurized discharge container 10, as shown in FIG. 1, a container body 12 is formed into a flat shape by a container wall 11 made of a thermoplastic resin film having flexibility. The container wall 11 includes a pair of side walls 13 and a bottom wall 14 disposed on the bottom side between the pair of side walls 13, and the bottom wall 14 is adjacent to both sides of the side wall 13 and an edge seal portion 12b. In the upper part of the bottom wall 14, the pair of side walls 13 facing each other are joined in a liquid-tight manner at the seal portions 12c on both side edges.

  Further, a hard discharge port 15 made of a hard resin is welded and joined to one side edge of both side walls 13, and the container body 12 is released by removing the closing member 16 of the hard discharge port 15. The inside and outside of can communicate.

  A standing structure 18 is formed on the bottom side of the container body 12 by joining the adjacent side wall 13 and bottom wall 14 so as to be deployable. The standing structure 18 can be deployed to place the container body 12 in an upright state by bringing the bottom edge 12a into contact with a flat placement surface. The standing structure 18 is provided over substantially the entire width between both side edges of the container body 12. Here, the standing structure 18 is preferably provided in the same width as the entire width between both side edges of the container main body 12 and may be substantially equivalent to the total width between the both side edges of the container main body 12.

  An accommodation port 19 is formed on the top side of the container body 12 by opposing the side walls 13 so as to be separated from each other. The storage port 19 is provided over substantially the entire width between both side edges of the container body 12. Further, a fastener 21 capable of sealing the accommodation port 19 is joined to the inner wall surface of the side wall 13 constituting the accommodation port 19. As the fastener 21, for example, a fastener member such as a hook-and-loop fastener having a protruding ridge portion continuous in the width direction and a groove portion that can be sealed by fitting the protruding ridge portion over the entire length can be used. Each fastener 21 is joined to the inner wall surface of the side wall 13 in a liquid-tight manner over the entire length.

  In such a container main body 12, a space between the container walls 11 between the fastener 21 and the standing structure portion 18 serves as the accommodating portion 22.

  The container 22 has a substantially square shape in a front view with the container body 12 in a flat shape. The shape of the housing portion can be selected as appropriate and can be a vertically long shape, but is preferably a substantially square shape or a horizontally long rectangular shape. For example, in a state in which the container body 12 has a flat shape, the height from the lower edge 12a substantially corresponding to the height of the container 22 to the full width of the container 22 substantially corresponding to the width of the container 22 in front view to the fastener 21 The ratio is preferably 3/5 or more and 1/1 or less, and if it is in such a range, it is preferable that the accommodating port 19 can be more easily expanded by expanding the standing portion 18.

  Further, an extension 23 is formed on the top side of the container main body 12 by arranging the side walls 13 on the top side of the fastener 21 so as to face each other without being joined at the intermediate part. . The extension 23 is provided to support the fastener 21 in a closed state during pressurization described later. The length from the fastener 21 to the top of the extension 23 is, for example, 5 mm or more, and the side wall 13 It is preferable to set it to 2/5 or less of the total length in the vertical direction.

  If the length of the extension portion 23 is excessively short, the fastener 21 is easily opened when the container wall 11 is pressurized. If the extension portion 23 is excessively long, it is difficult to accommodate the accommodated item when the accommodated object is accommodated from the accommodating port 19. When the standing structure 18 is unfolded, it becomes difficult to open the receiving port 19.

  Further, the pressurized discharge container 10 is configured such that the container main body 12 can be bent from the top side to the bottom side in a state where the contents are accommodated in the accommodation part 22. Here, the extension 23 on the top side of the container body 12 can be bent together with the fastener 21 to the hard discharge port 15 side by an arbitrary bending portion 25 along the width direction. By bending in this way, the internal pressure in the accommodating portion 22 is less likely to be directly applied to the closed fastener 21 during pressurization, which will be described later, so that the fastener 21 can be reliably maintained in the closed state. In the first embodiment, the position where the top edge of the container main body 12 is bent and arranged is displayed as the display unit 26 on the outer surface of the side wall 13 around the housing unit 22.

  In the pressurized discharge container 10 having such a configuration, the material of the container wall 11, the hard discharge port 15, and the fastener 21 constituting the container body 12 has flexibility and can be joined to each other. A material that does not contaminate the contents can be selected as appropriate, and a thermoplastic resin such as an olefin resin such as polyethylene or polypropylene can be used.

  Here, a laminated film having a layer structure such as polyethylene terephthalate (PET) / nylon (ON) / linear low density polyethylene (LLDPE), polypropylene (OPP) / ON / LLDPE is used as the container wall 11 on the inner surface side. If the LLDPE layer is used to be disposed on the surface, it is suitable for a method of using the pressurized discharge container 10 as described later.

  Next, a method of using the pressurized discharge container 10 as described above will be described. Here, an example in which a concentrated liquid food is administered to a patient using PEG (not shown) will be described.

  First, a flat container body 12 having opposite side walls 13 in contact with each other is prepared, the side walls 13 on the top side of the container body 12 are deformed in a direction away from each other, the fastener 21 is opened, and the container opening The side walls 13 constituting 19 are sufficiently expanded. Thereby, the accommodation port 19 formed in the full width of the container main body 12 is opened.

  Further, the side wall 13 on the bottom side of the container main body 12 is deformed in a direction to be separated from each other, and the side wall 13 and the bottom wall 14 are expanded. Thereby, the standing structure part 18 formed in the full width of the container main body 12 is developed.

  And the bottom edge 12a of the standing structure part 18 is made to contact | abut to plane parts, such as a mounting base, and as shown in FIG. 2, the container 10 for pressure discharge in the expand | deployed state is mounted.

  Next, the solid concentrated liquid food is introduced into the accommodating portion 22 through the accommodating port 19 opened from the top of the container main body 12, and a predetermined amount of diluted water is also opened from the top of the container main body 12. 19 is filled.

  And the fastener 21 is obstruct | occluded by pressing a pair of side wall 13 corresponding to the fastener 21 in the direction which mutually contacts from the outside. At this time, one end portion side of the fastener 21 is left open, and the remaining portion is closed.

  Thereafter, the container body 12 is preferably inclined so that one end side of the fastener 21 opened is higher than the other end side, and the outer surface of the container wall 11 corresponding to the accommodating portion 22 is pressed by hand. For example, the air remaining in the accommodating portion 22 is discharged from the opening portion of the fastener 21. As shown in FIG. 3, the fastener 21 is completely sealed in a sufficiently deaerated state.

  Furthermore, the concentrated liquid food in the accommodating part 22 is sufficiently dissolved in water by an operation such as squeezing from the outside of the container wall 11, and then the top side of the container body 12 is fastened together with the fastener 21 as shown in FIG. At an arbitrary folding part 25 along the direction, it is bent toward the hard outlet 15 side. Thereby, the side wall 13 on the side of the accommodating portion 22 from the fastener 21 is bent in a contact state. At this time, it is possible to bend at an appropriate position by matching the top of the container body 12 with the display unit 26.

  Next, as shown in FIGS. 5 to 7, the pressurized discharge container 10 in a state in which the contents are accommodated and bent is attached to the pressurizing device 35.

  As shown in FIG. 5, the pressurizing device 35 includes a pump unit 37 that can supply air from the flow path 36, a bag-shaped pressurizing unit 38 that expands when air is introduced, and a bag-shaped pressurizing unit. 6 is provided between the surface of the bag-like pressurizing portion 38 and the support cloth 39. The support cloth 39 is disposed opposite to the surface of the face 38 and has both side edges 39b fixed to the bag-like pressurizing portion 38. As described above, the pressurized discharge container 10 in a folded state is configured to be accommodated.

  When the pressurized discharge container 10 is mounted on the pressurizing device 35, the hard discharge port 15 is disposed in a state of protruding from the support cloth 39, as indicated by a virtual line in the drawing.

  Then, as shown in FIG. 7, the blocking member 16 is detached from the hard discharge port 15, the fitting portion 17 b of the extension pipe 17 is fitted, and the standard tapered PEG provided at the tip of the extension pipe 17. A PEG (not shown) is connected and attached to the connecting portion 17a. After that, the bag-shaped pressurizing unit 38 is expanded by the pump unit 37, thereby pressing the container wall 11 of the pressurized discharge container 10 and increasing the internal pressure in the accommodating unit 22. Thereby, the contents in the accommodating part 22 are discharged | emitted from the hard discharge port 15, and can be administered to a patient from PEG.

  According to the pressurized discharge container 10 as described above, the top-side storage opening 19 and the bottom-side standing structure 18 are provided over substantially the entire width between both side edges of the container body 12. Since the deformed shape of the side wall 13 when opening the opening 19 and the deformed shape of the side wall 13 when unfolding the standing structure 18 on the bottom side are the same shape, each side wall 13 is easily deformed, and the standing structure portion It is easy to expand both 18 and the storage port 19. Moreover, since the hard discharge port 15 is joined to the side edge of the container body 12, when both the top-side storage port 19 and the bottom-side standing structure portion 18 are expanded, the hard discharge port 15 The deformation of the container wall 11 is not hindered.

  Therefore, both the accommodation port 19 and the standing structure portion 18 can be sufficiently expanded at the same time. Further, it is easy to maintain the side wall 13 in a deformed state, and it is also possible to maintain the opening 19 by opening the standing structure portion 18. As a result, operations such as storing concentrated liquid food, diluted water, and the like from the storage port 19 in the storage portion 22 can be easily performed.

Fasteners 21 are provided along the width direction of the container body 12, and the top side of the container body 12 is bent along the width direction together with the fasteners 21 in the width direction, so that the fasteners 21 are side walls 13 on the hard discharge port 15 side. Therefore, even if the container opening 19 is formed to have a substantially full width of the container body 12, the inner wall surfaces of the side walls 13 facing each other on the container 22 side of the fastener 21 are brought into contact with each other and folded back. Therefore, it is difficult for the internal pressure in the housing portion 22 to act on the fastener 21, and it is easy to maintain the closed state of the fastener 21 during pressurization.

It is equivalent to the side edge seal portion 12c. As a result, a protruding portion 22 a that bulges toward one end of the fastener 21 in the vicinity of the fastener 21 is formed in the accommodating portion 22 formed between the seal portions 12 c and 32 c on both side edges.

Even with such a pressurized discharge container 30, the same effects as those of the first embodiment can be obtained. Moreover, after storing the high-concentration liquid food and dilution water in the storage part 22, as shown in FIG. 9, the end part side of the fastener 21 on the projecting part 22a side is opened and the remaining part is closed, and the pressure is discharged. If the container 30 is tilted and the protruding portion 22a side is disposed obliquely upward, the air remaining in the accommodating portion 22 can be collected on the protruding portion 22a side, so that from the open end side of the fastener 21, The air in the accommodating part 22 can be discharged efficiently, the air remaining in the accommodating part 22 can be suppressed to a small amount, and can be eliminated.
