Description

  The present invention relates to a storage pack, and more specifically, has a first sheet portion and a second sheet portion facing the first sheet portion, and flows between the second sheet portion and the first sheet portion. TECHNICAL FIELD The present invention relates to a storage pack including a pack body in which a storage having a property is sealed.

  Conventionally, one sheet is folded in half and sealed on three sides, or two sheets, a front sheet and a back sheet, are overlapped and sealed on four sides to seal the accommodation part for accommodating contents inside. A rectangular package viewed from the front in a state is widely used. This type of package is used for sealing a container having fluidity such as a liquid (hereinafter also referred to as a “fluid container”). A storage pack in which the package is provided as a pack body for storing a flowable storage material is used for various applications.

  Conventionally, when distributing a sample such as a shampoo or a rinse, for example, as shown in FIG. 7, the pack body 10x containing the product is fixed to one side of a backing sheet 20x on which a description of the product is given.

The storage pack according to the present embodiment will be described with reference to the drawings.
As shown in FIGS. 1 and 2, the storage pack 1 of the present embodiment has a pack body 10 having a vertically long rectangular shape when viewed from the front. The pack main body 10 accommodates a fluid container inside by folding one sheet so that the sheets are overlapped with each other and bonding the sheets together at a location that becomes a peripheral portion of the pack main body 10. Receiving section 10a is formed.

  The pack body 10 of the present embodiment has a first sheet portion 11 as one portion of the stacked sheets and a second sheet portion 12 as the other portion. The first sheet portion 11 constitutes the front side of the pack body 10, and the second sheet portion 12 constitutes the back side of the pack body 10. That is, the pack body 10 of the present embodiment has the first sheet portion 11 and the second sheet portion so as to face each other in the thickness direction of the pack body 10. In the pack body 10 of the present embodiment, a fluid container is sealed between the first sheet portion 11 and the second sheet portion 12.

  The sheet constituting the pack main body 10 of the present embodiment is folded at one long side of a rectangle which is the contour shape of the pack main body 10, and the sheet is located at a position along the other long side and two short sides. The edge seals 14 are bonded together. That is, the edge seal 14 of the pack body 10 of the present embodiment includes a long side seal 14a along one long side of the rectangle and a short side from one edge (upper edge) of the long side seal 14a. The first short side seal 14b extends along the short side from the other edge (lower edge) of the long side seal 14a.

  On the long side opposed to the long side seal 14a, the sheet is not only folded but also slightly woven inside to form the side gusset 13. The pack main body 10 of the present embodiment extends along the direction from the center in the longitudinal direction of the long side where the side gussets 13 are formed to the center of the opposing long side across the pack main body 10. It further includes a transverse seal 15 to which the one sheet portion 11 and the second sheet portion 12 are bonded.

  The pack body 10 of the present embodiment is provided with a first storage portion 10a1 and a second storage portion 10a2 that are adjacent to each other via the transverse seal 15 as the storage portion 10a that stores the fluid storage material. As described above, the pack body 10 of the present embodiment includes the edge seal 14 to which the first sheet portion 11 and the second sheet portion 12 are adhered along the outer peripheral edge of the pack body 10. The transverse seal 15 extends in a direction orthogonal to the long side seal 14a of the edge seal 14, and does not reach the long side seal 14a. Thereby, the communication part which connects the said 1st accommodating part 10a1 and the said 2nd accommodating part 10a2 between the front-end | tip of the said transverse seal 15 and the said edge part seal 14 is provided in the said pack main body 10 of this embodiment. 10b are formed.

The pack body 10 of the present embodiment is configured such that the first sheet portion 11 and the second sheet portion 12 constituting the first storage portion 10a1 and the second storage portion 10a2 approach each other. By applying pressure to the first storage portion 10a1 and the second storage portion 10a2, the fluid storage material stored therein can be moved to the communication portion 10b. In the communication portion 10b from which the flowable material has moved from the first storage portion 10a1 and the second storage portion 10a2, the first sheet portion 11 and the second sheet are moved by the pressure of the flowable material. The part 12 moves in a direction away from each other to increase the accommodation volume. Further, when pressure is applied, the first sheet portion 11 and the second sheet portion 12 that constitute the long side seal 14a are located inside the portion adjacent to the communication portion 10b (a portion having an easy peeling property). Begins to peel outward from the Then, as the pressurization of the first storage portion 10a1 and the second storage portion 10a2 is continued, the separation progresses to completely cross the long side seal 14a. An object is discharged to the outside of the pack body 10. Therefore, the portion adjacent to the communication portion 10b and where the edge seal 14 has the easy peeling property is, in other words, expected to be a discharge flow path to the outside of the fluid container. Part. The manner in which the first sheet portion 11 and the second sheet portion 12 are separated from each other at a portion of the edge seal 14 adjacent to the communication portion 10b (that is, a portion having easy peelability) is not particularly limited. For example, at least one mode selected from delamination, interfacial delamination, and cohesive delamination is mentioned.

  In order for the edge seal 14 to exhibit such an easy peeling property, the sheet constituting the first sheet portion 11 and the second sheet portion 12 may have an easy peeling property.
