Description

  The present invention relates to an article storage pouch formed by laminating a flexible packaging film.

  Conventionally, as a storage container using a soft packaging film, there are various types of pouches such as a flat pouch with a three-way or four-side seal, which is the simplest shape, a back bonded palm type, a gusset type, and a standing pouch. in use.

  In the case of a pouch in which curry or other relatively high-viscosity contents are stored, an operation of squeezing the contents after opening is necessary to sufficiently remove the contents. Conventional flat pouches are somewhat large in size, and especially for people with small hands, it is difficult to use because it is necessary to squeeze the contents many times with hands. It was.

  The easy squeeze pouch described in Patent Document 1 is intended to solve such problems, and its contents are as described in the claims, from the dispensing portion by applying external pressure. A pouch configured to take out the contents is provided with a take-out seal portion formed with a pour-out portion on the upper surface or the back surface of the pouch, and the length of the take-out seal portion is equal to the length of the seal portion parallel to the take-out seal portion. An easily squeezable pouch characterized by having the same or almost the same length. When using this pouch, use the easy-open part formed in the take-out seal part to open the pour-out part, and then overlap the back side with the take-out seal part as a boundary. Fold the pouch in half so that it is on the outside. Next, the contents of the pouch folded in half are taken out with one or both hands and taken out.

  According to the pouch described in Patent Document 1, although the efficiency of squeezing is improved by grasping the pouch folded in half by hand, there is no means for accurately folding the pouch in a diagonally shifted state. In the case of being folded in half, there is a disadvantage that an undrawn portion is generated. In the first place, since it is necessary to perform the operation of folding in half, there is a problem that it is difficult to understand the correct usage for those who are not used to it.

Also, as another problem of flat pouches, the pouch itself is not self-supporting, so if you leave the opened pouch and do some other work, let it lean against something else. Otherwise, the contents would fall and the contents would spill, so there were many times when I felt inconvenient.
Standing pouches have been developed to solve this problem, but they are disadvantageous in terms of cost because of their bulky shape and the use of rigid, thick materials to ensure their independence. In addition, there is a problem that the squeezing property of the contents is inferior because the material is thick.
JP 2001-206387 A

  The problem to be solved by the present invention is to propose an easy-to-use pouch that is excellent in squeezing contents and is self-supporting.

As a means for solving the above-mentioned problems, the invention according to claim 1 is a pouch having two storage parts, and is composed of a front film, a back film, and an inner film, and the inner film is an upper part of the pouch. The inner film and the surface film form a first storage part by a bottom seal part and a side seal part, and the inner film and the back film are bottoms. A second storage part is formed by a seal part and a side seal part, and the top film and the back film are extended longer than the folding position of the inner film to form a top seal part. A pouch having two storage portions.

  The invention according to claim 2 is a pouch having two storage parts according to claim 1, wherein the first storage part and the second storage part have the same shape. is there.

  The invention according to claim 3 is characterized in that a discharge space is formed between the bending position of the inner film and the top seal part, and the two storage parts according to claim 1 or 2, It has a pouch.

  According to a fourth aspect of the present invention, there is provided an adhesive portion that can be peeled between the discharge space and / or one of the first storage portion and the second storage portion, and two storage portions. The pouch having two storage portions according to claim 3, wherein different contents can be stored in each storage portion by preventing communication between the two.

  The pouch according to the present invention comprises a front film, a back film, and an inner film, and the inner film is folded with the outer surface facing inward at a folding position at the top of the pouch, and the inner film and the surface film are A bottom seal part and a side seal part form a first storage part, the inner film and the back film form a second storage part by a bottom seal part and a side seal part, and the surface film and the back film are By extending the inner film longer than the folding position of the inner film and forming the top seal portion, the first storage portion and the second storage portion are overlapped with the top seal portion as the center. Yes. Accordingly, by cutting the top seal portion with scissors or the like, the two storage portions are opened simultaneously, so that the contents can be efficiently discharged by manually pressing the two storage portions.

  When the first storage part and the second storage part have the same shape, the two storage parts overlap each other, so that the contents can be discharged more efficiently.

  In addition, the pouch according to the present invention has a shape in which the two storage portions are distributed around the top seal portion, so that the bottom seal portion of each of the first storage portion and the second storage portion faces downward. You can stand up or stand like a folding screen with the side seals down. Since this property does not change even after opening, it is possible to stand the contents so that they do not spill after opening, which is convenient.

  This self-supporting property is a property that develops from the shape itself without using a particularly thick and strong film as a constituent material, so it does not impair the squeezability of the contents and is advantageous in terms of cost. .

  Also, compared to a flat pouch of the same capacity, the size is almost halved, so that even a person with a small hand can easily perform the squeezing operation. Also, the size of the outer box is larger than that of a flat pouch of the same capacity, but the size is almost halved. Therefore, the area of cardboard required for the outer box is small.

When a discharge space is formed between the folding position of the inner film and the top seal part,
The discharge space can be easily opened by cutting with scissors.
Further, by providing an easy opening means such as an opening notch, a cut line, and a half-cut process in the discharge space, the opening is further facilitated.

When a peelable adhesive portion is provided between each or one of the first storage portion and the second storage portion and the discharge space so that the two storage portions do not communicate with each other, the respective storage portions It is possible to store different contents in the part without mixing them.
For example, in the case of white hair dyeing where two liquids A and B are mixed and used as an example, liquid A is stored in the first storage part, and liquid B is stored in the second storage part. By pressing the contents so that the peelable adhesive portion is opened, it is possible to simultaneously extrude while mixing the A and B2 liquids in the discharge space.

In the pouch according to the present invention, the inner film is bent, and the top film portion and the back film form the top seal portion at the upper portion of the bent position, so the first storage portion and the second storage portion. Can be communicated, and when the same contents are stored in these two storage parts, only one of the bottom seal parts is used as an opening for filling, and all the contents are filled from here. be able to.
In this case, the pouch immediately after the filling is completed has a shape like a flat pouch, but since the folds are present in the inner film, it can be easily folded at the correct position.

The best mode for carrying out a pouch having two storage portions according to the present invention will be described in detail with reference to the drawings.
FIG. 1 is a perspective view showing an embodiment of a pouch having two storage portions according to the present invention. FIG. 2 is a cross-sectional explanatory view showing cross sections AB, C of the pouch shown in FIG.

The pouch having two storage portions according to the present invention is composed of a front film 1, a back film 2, and an inner film 3, and the inner film 3 is folded with the outer surface facing inward at a folding position 9 in the upper part of the pouch. The inner film 3 and the surface film 1 form a first storage portion 11 by the bottom seal portion 6 and the side seal portion 4, and the inner film 3 and the back film 2 are second by the bottom seal portion 7 and the side seal portion 5. The front film 1 and the back film 2 are extended longer than the folding position 9 of the inner film to form the top seal part 8.

  At the top of the pouch, the inner film 3 and the front film 1 are not sealed, and the inner film 3 and the back film 2 are not sealed. The top seal 8 is formed by the front film 1 and the back film 2. Therefore, as shown in FIG. 2, the first storage portion 11 and the second storage portion 12 communicate with each other at the zenith portion.

  Although the first storage portion and the second storage portion communicate with each other but form independent spaces, it is possible to store different contents without any problem even in a common atmosphere. Of course, the same contents may be stored. When storing different contents, the bottom seal part or the side seal part of each storage part is opened in an unsealed state in advance and sealed after filling. When storing the same contents, it is possible to fill the contents from one of the bottom seal portions.

When opening the pouch of FIG. 1, if the corners of the top seal portion 8 and the side seal portions 4, 5 are cut diagonally with scissors or the like, the two storage portions open simultaneously, so that they are stored in the two storage portions. The extracted contents can be squeezed out simultaneously.
At this time, if the size and shape of the two storage parts are made the same, the operation of squeezing out can be performed smoothly without any remaining aperture.

  In order to facilitate the opening, it is optional to provide an easy opening means such as providing a notch for opening in the top seal part 8 or the side seal parts 4, 5 or the like, or providing a half-cut cutting line. Can do.

  The pouch according to the present invention, as seen in FIG. 1, is essentially self-supporting, whether the contents are stored or emptied or unopened. Even if it is in the state of being opened or not, its properties are not changed. Although not shown in the figure, it can be set up like a folding screen with the side seal part facing down.

  Also, the pouch of the present invention can be opened and crushed flat to form a flat pouch. In such a case, it can be inserted into a flat outer box. Even in this case, when the contents are squeezed out, the folding line remains on the inner film, so that it can be easily folded in two at an accurate position.

  FIG. 3 is a perspective view showing another embodiment of a pouch having two storage portions according to the present invention. In the present embodiment, a discharge space 15 is provided between the inner film folding position 9 and the top seal portion 8. Further, the top seal portion 8 is provided with a bulge in the center portion, and an opening notch 10 is provided here. By adopting such a structure, it is possible to easily tear the film in the discharge space from the opening notch 10 and provide an opening in the planned opening 13.

  FIG. 4 is a perspective view showing another embodiment of a pouch having two storage portions according to the present invention. Similarly, in the present embodiment, a discharge space 15 is provided between the folding position 9 of the inner film and the top seal portion 8. In the present embodiment, a part of the top seal portion 8 is cut away so that the planned opening portion 13 protrudes. The opening notch 10 was provided on the side surface of the top seal portion 8. By taking such a structure, the opening operation is further facilitated.

FIG. 5 is a perspective view showing another embodiment of a pouch having two storage portions according to the present invention. In the present embodiment, similarly to the previous embodiment, a discharge space 15 is provided between the inner film folding position 9 and the top seal portion 8, and a part of the top seal portion 8 is cut out to form an opening planned portion 13. It formed so that it might protrude. The opening notch 10 was provided on the side surface of the top seal portion 8. Further, a peelable adhesive portion 14 is provided between the first storage portion 11 and the discharge space 15 and between the second storage portion 12 and the discharge space 15 and immediately below the inner film folding position 9. By preventing the first and second storage portions 11, 12 and the discharge space 15 from communicating with each other, different contents can be stored in the respective storage portions.
As the peelable adhesive portion 14, a known easy peel sealing tape can be suitably used.

  In the embodiment of FIG. 5, it is possible to store different contents in the two storage units. These stored items can be stored without problems even if it is not preferable to mix them before use. Examples of such contents include white hair dyeing using a mixture of the two liquids listed above, a two-liquid mixing type adhesive, paint, etc., and finally mixing but using them separately. Foods that are more advantageous for maintaining freshness, such as dressings and seasonings that are used by mixing vinegar and oil, can be mentioned.

In using the pouch of the embodiment of FIG. 5, the two storage parts are first compressed from the outside to increase the internal pressure, and the peelable adhesive part 14 is peeled off by this pressure. As a result, the contents stored in the two storage units are mixed in the discharge space 15. Then, the opening notch 10 is used to tear and open the film of the planned opening portion 13 to push out the contents. By following such an opening procedure, the contents can be safely opened without the risk of the contents being scattered when the peelable adhesive portion is opened by pressing the storage portion from the outside.

  In the embodiment of the pouch according to claim 4, only one peelable bonding portion is provided between the storage portion of either the first storage portion or the second storage portion and the discharge space. However, it may be provided in each storage section as described above.
