Each of the sheets 11 to 13 is a laminated sheet having the same layer structure. The dots shown in FIG. 1 and FIGS. 4 to 6 indicate heat-sealed portions.

  An example of the laminated sheet includes an outermost layer, an intermediate layer, and an innermost layer. An example of the material of the outermost layer is polyethylene terephthalate. An example of the intermediate layer includes a printing layer, a first adhesive layer, a stretched nylon layer, and a second adhesive layer. The print layer is formed inside the outermost layer. The printed layer is printed with a picture, a text describing a product, and the like on the outer surface. The first adhesive layer is formed inside the printing layer. The stretched nylon layer is formed inside the first adhesive layer. The second adhesive layer is formed inside the stretched nylon layer. The innermost layer is formed inside the second adhesive layer. An example of the innermost layer material is unstretched polypropylene.

  The pouch 10 includes a storage part 20, a protruding part 30, a cutout part 40, a bottom gusset 50, and a liquid injection assisting part 100. The accommodating part 20, the protruding part 30, and the cutout part 40 are part of the first sheet 11 and the second sheet 12.

  The storage unit 20 forms a storage space 21 to which the contents 150 (see FIG. 4) are supplied. A scheduled seal portion 22 is formed on the upper portion of the accommodating portion 20. The planned sealing portion 22 is a portion opened because the first sheet 11 and the second sheet 12 are not heat-sealed. The content 150 (see FIG. 4) is supplied to the accommodation space 21 through the opening of the planned sealing portion 22.

  The protrusion 30 is another part of the first sheet 11 and the second sheet 12 that is continuous with the part of the first sheet 11 and the second sheet 12 that constitutes the storage part 20, and is located above the storage part 20. It protrudes from the part. A spout 31 is formed inside the protrusion 30. The spout 31 communicates with the accommodation space 21.

  The cutting part 40 is another part of the first sheet 11 and the second sheet 12 that is continuous with the part of the first sheet 11 and the second sheet 12 that constitutes the protruding part 30, and closes the spout 31. Have a role. A notch 41 and a guide line 42 are formed at the boundary between the cutout 40 and the protrusion 30. The cut portion 40 is separated from the protruding portion 30 by cutting the boundary portion between the cut portion 40 and the protruding portion 30.

  The liquid injection assisting part 100 is made of a resin material. The resin material has a property of being deformed by a relatively weak force applied by the user. A preferred example of the resin material is polypropylene or polyethylene terephthalate. The liquid injection assisting part 100 is mainly arranged at the spout 31. The tip of the liquid injection assisting part 100 is arranged in the accommodation space 21 side of the spout 31 relative to the guide wire 42. A part of the liquid injection assisting part 100 is disposed in the accommodation space 21. The liquid injection assisting part 100 has a role of suppressing the blocking of the spout 31 and a function of easily squeezing the contents from the spout 31. A gap LA is formed between the edge of the liquid injection assisting part 100 and the inner edge 30 </ b> A of the protrusion 30. The inner edge 30 </ b> A is an edge of the first sheet 11 and the second sheet 12 on the spout 31 side in the heat seal portion. As an example, the length of the gap LA is longer than the seal width LB of the protrusion 30.

With reference to FIG. 2, the structure of the liquid injection assistance part 100 is demonstrated.
As shown in FIG. 2A, the liquid injection assisting part 100 includes a flat plate portion 110 and a curved portion 120. The flat plate portion 110 is formed continuously with the curved portion 120. The flat plate portion 110 has an area that ensures a preferable seal strength.

  As shown in FIG. 2 (b), the curved portion 120 includes three peaks 121. The curved portion 120 extends in the direction of the passage of the spout 31 when a force for crushing the mountain 121 is applied. The length of the curved portion 120 in the longitudinal direction of the liquid injection assisting part 100 is longer than the length of the flat plate portion 110. The mountain 121 has a height at which the passage area of the spout 31 is maintained at a preferable size.

FIG. 3 shows the relationship between the sheets 11 and 12 and the liquid injection assisting part 100.
The flat plate portion 110 is disposed in the accommodation space 21. The flat plate portion 110 is heat-sealed with the first sheet 11. The tip of the curved portion 120 is disposed near the portion where the spout 31 opens. As an example, the distance LC between the tip of the curved portion 120 and the guide line 42 is shorter than the length of the gap LA shown in FIG.

With reference to FIG. 4, the manufacturing process of the content enclosure pouch 1 is demonstrated.
In the first step, the flat plate portion 110 of the liquid injection assisting part 100 is heat sealed to the single first sheet 11. In the second step, the first sheet 11, the single second sheet 12, and the single gusset sheet 13 to which the liquid injection assisting part 100 is bonded are heat sealed. In the third step, the notch 41 and the guide line 42 are formed. In the fourth step, shampoo, which is an example of the contents 150, is supplied from the planned sealing portion 22 to the accommodation space 21. In the fifth step, the planned sealing portion 22 is heat sealed. By completing the fifth step, the entire pouch 10 is sealed, and the content-filled pouch 1 is completed.

With reference to FIGS. 5-7, the effect | action of the content enclosure pouch 1 is demonstrated.
As shown in FIG. 5, when the content 150 is supplied to the container 160, the cutout portion 40 is cut out from the protruding portion 30 by the user. For this reason, the spout 31 opens.

  As shown in FIG. 6, the spout 31 is directed to the container 160. For this reason, the content 150 accommodated in the accommodation space 21 passes through the spout 31 and is supplied to the container 160. Even in a state where most of the content 150 is supplied to the container 160, a part of the content 150 may remain inside the pouch 10. The contents 150 are mainly attached to the portion of the first sheet 11 and the second sheet 12 forming the spout 31 and the liquid injection assisting part 100. Such a state in which a part of the content 150 remains inside the pouch 10 is generally called a liquid residue. As the viscosity of the content 150 is higher, the liquid residue is more likely to occur.

  When the liquid residue is generated, the user crushes the space inside the pouch 10 and squeezes the remaining content 150 to the outside of the pouch 10. FIGS. 7A and 7B show an example of the progress of such work.

  As shown in FIG. 7A, a force that pushes around the root portion of the protrusion 30 is applied to each of the sheets 11 and 12 by the user. At this time, the curved portion 120 of the liquid injection assisting part 100 receives a force applied by the user. For this reason, the curved portion 120 extends in the longitudinal direction of the liquid injection assisting part 100. For this reason, even if a user does not apply big force to the pouch 10, a part of the spout 31 and a part of the accommodation space 21 are crushed. By crushing these portions, the remaining contents 150 are sent out toward the outlet of the spout 31.

  As shown in FIG. 7B, after the root portion of the projecting portion 30 is crushed, a force that pushes the intermediate portion and the tip portion of the projecting portion 30 is applied to the sheets 11 and 12 by the user. At this time, the curved portion 120 extends in the longitudinal direction of the liquid injection assisting part 100 in the same manner as described above. For this reason, even if a user does not apply big force to the pouch 10, a part of the spout 31 is crushed. For this reason, the remaining content 150 is squeezed out of the pouch 10 from the opening of the spout 31.

The pouch 10 according to the first embodiment has the following effects.
(1) The curved portion 120 of the liquid injection assisting part 100 separates the first sheet 11 and the second sheet 12 forming the spout 31 from each other. For this reason, the spout 31 is not easily blocked. For this reason, the contents 150 easily pass through the spout 31. Further, when the user applies a force to crush the spout 31 in order to send out the contents 150 to the outside, the curved portion 120 of the liquid filling auxiliary part 100 is deformed and extends in the direction of the passage of the spout 31. For this reason, the first sheet 11 and the second sheet 12 forming the spout 31 approach each other, and the content 150 staying at the spout 31 is pushed out of the pouch 10. For this reason, it becomes difficult to produce liquid residue.

  (2) The flat plate portion 110 has an area in which a preferable seal strength is ensured. The flat plate portion 110 is heat sealed to the first sheet 11. For this reason, the sealing strength of the liquid injection assisting part 100 and the first sheet 11 is increased. For this reason, the liquid injection assisting part 100 is difficult to separate from the first sheet 11.

  (3) The flat plate portion 110 is not substantially deformed even when a force that causes the first sheet 11 and the second sheet 12 to approach each other is applied. For this reason, when it is assumed that the flat plate portion 110 is disposed at the spout 31, even if the user applies a force to the portion where the force is particularly applied to send the contents 150 to the outside of the pouch 10, no deformation occurs. There will be an object. Such a configuration can be obtained when the user is performing the operation of squeezing the content 150 as compared with a configuration in which the deformable curved portion 120 exists in a wider range of the spout 31. There is a possibility that it may be difficult to give the user the feeling of squeezing 150.

  According to the pouch 10, such a flat plate portion 110 is heat-sealed to a part of the first sheet 11 forming the accommodation space 21. For this reason, it is easy to give the user the feeling of squeezing the contents 150.

  (4) The tip portion of the liquid injection assisting part 100 exists near the guide line 42, that is, near the opening of the spout 31. For this reason, in the wider range of the spout 31, the spout 31 becomes difficult to be obstruct | occluded. For this reason, the contents 150 can easily pass through the spout 31.

  (5) The pouch described in Patent Document 1 has a structure in which the cylindrical body is in close contact with the inner surface of the protruding portion. Such pouches are often manufactured by the following procedure. First, a cylindrical body is placed on one sheet constituting the pouch. Next, the other sheet constituting the pouch is placed on the one sheet and the cylindrical body. Next, the edges of each sheet are heat sealed. At this time, a relatively large stress is generated in the seal portion inside the protrusion. For this reason, after each sheet is heat-sealed, there is a possibility that the seal portion of the protruding portion may be peeled off.

  On the other hand, in the pouch 10, a gap LA is formed between the edge of the liquid injection assisting part 100 and the inner edge 30 </ b> A of the protrusion 30. For this reason, when each sheet | seat 11 and 12 is heat-sealed, it is hard to produce a big stress in the sealing part of the protrusion part 30. FIG. For this reason, the seal part of the protrusion 30 is difficult to peel off.
