Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

TECHNICAL FIELD The present invention relates to a storage bag,
In particular, the present invention relates to a storage bag body having a storage portion inside by heat sealing a peripheral portion of a sheet member.

[0002]

2. Description of the Related Art A storage bag such as a standing pouch having a storage portion for storing a liquid or a granular material therein, which is formed by heat-sealing the periphery of a plurality of sheet members. However, even if the user tries to dispose of the contents by folding them down after using them, the bag will spread to a flat state close to the shape before the contents are filled if left as it is.

[0003] In order to hold the bag in a folded state, a method of using a rubber band, a string, an adhesive tape, a clip, or the like is adopted, but when there is no such thing near, , And the bag was discarded with the spread flat.

[0004] It is an object of the present invention to provide a storage bag that can be disposed of in a compact state after use of the contents.

[0005]

A storage bag according to the present invention is a storage bag obtained by heat sealing the periphery of a plurality of sheet members. Have a cut-out guide line. The cut-out guide line is formed by processing the sheet member in advance so that the sheet member can be easily torn along the guide line, and can be constituted by a perforation, a thin line, or the like. The ring-shaped piece obtained by cutting has a size that can be fitted around the folded storage bag after use, and inserted into the folded storage bag to make it compact. Shape is maintained.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A storage bag 10 according to a preferred embodiment of the present invention is a bag for refilling or replacement, and as shown in FIG. A storage portion is provided for storing a liquid or a granular material inside by heat sealing.

The storage bag 10 has a spout 14 protruding upward from an upper edge 13 of the heat-sealed pair of front and back sheet members 11, and is separately provided from the upper edge. Both end portions 15 protruding from 13 have projecting pieces 16 which are sealed. At the base end portion of the protruding piece 16 close to the upper edge 13, an annular piece 17 (see FIG. 2) is formed by cutting the protruding piece 16 which is a part of the storage bag body 10. A guide line 18 is provided.

The storage bag 10 has a plurality of sheet members 11 formed by laminating plastic films in multiple layers and heat-sealed to each other to form a sealed space for accommodating a liquid or a granular material therein. It is about 15 cm wide and 25 cm high.

The spout 14 is provided at the corner of the storage bag 10 in the storage bag 11 of the present embodiment for refilling so that the contents can be easily transferred to another container. At the time of use, the spout can be easily torn manually along the cutout indication line 22 above the spout 14, and the spout can be opened at the tip of the spout 14 so that the contents can be taken out. .

The protruding piece 16 is formed by cutting each horizontally elongated piece 19 integrally formed with the pair of front and back sheet members 11 constituting the accommodating portion of the accommodating bag body 10 with the heat-sealed upper edge 13 interposed therebetween. , And are formed by heat-sealing the side ends 15 of these horizontally long pieces 19 with each other. A cutout guide line 18 is provided at the base end portion of the protruding piece 16 near the upper end edge 13 as described above. Also,
The upper end of the protruding piece 16 is also sealed so that the pair of horizontally long pieces 19 are united to prevent the tip of the upper end from being sharpened. An auxiliary cutting guide line 20 extending parallel to the line 18 is provided so that the sealing portion can be easily removed from the projection 16.

The protruding piece 16 has a width in the lateral direction of 5c.
m, so that the annular piece 17 obtained by cutting after use has a size that can be easily inserted around the folded or rounded storage bag body 10. Become. In addition, such protrusion 1
6 is not limited to the upper edge 13 and can be provided so as to protrude from other edges. However, by providing the upper edge 13 alongside the spout 14, the pair of front and back sheet members 1 is provided.
When cutting 1, each horizontally long piece 19 is formed by effectively using the sheet of the originally discarded portion, and the protruding piece 16 can be provided efficiently.

According to the present embodiment, the cutting guide line 18
Is provided, so that the protruding piece 16 is cut along the auxiliary cutting guide line 20 to remove the upper end sealing portion of the protruding piece 16, and the protruding piece 16 is cut off along the guiding line 18. As shown in FIG. 2, an annular section 17 is obtained. The empty storage bag body 10 is folded or rolled up by using the contents, and the storage bag body 10 is inserted into the annular section 17 to obtain the storage bag body 10. It is kept compactly folded. Therefore, the storage bag 10 can be discarded in a compact state after using the contents without using rubber bands, strings, adhesive tapes, clips, or the like.

The present invention is not limited to the above embodiment. For example, it is not always necessary to provide a projecting piece and arrange a cutting guide line for forming an annular piece at the base end thereof. If an annular section large enough to allow the inserted storage bag body to be inserted can be obtained, it can be provided below the cutout display line of the spout, and by cutting the spout along this, the annular shape can be obtained. Sections can also be obtained. Also, the upper end of the projection need not necessarily be sealed.

[0014]

According to the storage bag of the present invention, it is possible to easily dispose of the bag in a compact state after using the contents without using rubber bands, strings, adhesive tapes, clips or the like. .
