Description

DETAILED DESCRIPTION OF THE INVENTION The present invention is a bag-like container made of a composite film having a heat-adhesive synthetic resin layer on the inner surface for packaging so-called tissue paper for cosmetics or miscellaneous goods, confectionery, etc. A tongue-shaped portion to be removed that forms an opening for taking out the material is formed, a linear or broken cut is formed at the periphery of the removal start portion of the portion to be removed, and the portion to be removed is covered with adhesive tape. The present invention relates to a packaging container characterized by adhesive attachment, and is particularly suitable for packaging wet-type tissue paper.

Conventionally available packaging bags for storing wiping paper impregnated with cleaning liquid, facial cleansing liquid, etc. have a complicated structure because they must be sealed when not in use to prevent the cleaning liquid from evaporating. Most of the containers were in the form of a hard container with a sealed lid, but they had drawbacks such as being complicated and expensive to manufacture.As a result of various experimental studies, the present inventor has developed the present invention which does not have these drawbacks. I got it.

Hereinafter, embodiments of the present invention will be described with reference to the drawings.
A heat-adhesive synthetic resin layer 1 of polyethylene, polypropylene, etc., having a thickness of 0 to 100 μm is uniaxially stretched at a stretching ratio of 2 to 10 times. The composite film 3 is formed by laminating the composite film 3 by an adhesive means of
The composite film 3 may be formed by laminating an air-proof film 4 such as aluminum foil with a thickness of 10 to 50 μ or a reinforcing film 5 such as polypropylene or polyester with a thickness of 10 to 50 μ by an appropriate means, or an axially stretched synthetic resin film. A reinforcing film 5 as described above is laminated on the outer surface of the composite film 2 by an appropriate means to form a composite film 3. The composite film 3 as described above is overlapped with the heat-adhesive synthetic resin layer 2 as the inner surface, and folded in half.

A bag-shaped container 6 with a width of 5 to 1° and a length of 10 to 20 cNL is prepared by using an appropriate bag-making method such as a sticker on the back, or a body wall is formed using the heat-adhesive synthetic resin layer 2 of the composite film 3 as the inner surface,
Another mountain-folded bottom wall is inserted into the lower end, and the necessary peripheral edges are thermally bonded to form a bag-like container 6 consisting of a self-supporting bag. 5~5c
In, a tongue-shaped portion 8 to be removed for forming an open lower portion having a length of 2 to 15 cIIL is formed in a direction that coincides or substantially coincides with the orientation direction B of the uniaxially stretched synthetic resin film 2, and the portion 8 to be removed is removed. A part of the periphery of the starting part 9 has an arc shape.

Linear or broken line cut of appropriate shape with acute angle shape 1
0, which is wider than the portion to be removed 8 and has a width of 1 to 6 CIr.
L, length 3-17crIL, thickness 7-100μ polyethylene, polypropylene, polyester.

An adhesive tape 13 coated with an appropriate adhesive 12 such as acrylic or rubber at 10 to 50 g/m'' is applied to the inner surface of a sheet 11 made of a synthetic resin such as nylon, aluminum foil, or a laminate thereof. The adhesive tape 13 is coated and attached, and the peeling direction C of the adhesive tape 13 is made to match the orientation direction B of the uniaxially stretched synthetic resin film 2. In the figure, 14 is a knob that is applied when peeling the adhesive tape 13, and 15 is a knob that is scheduled to be removed. This is a removed portion that has been removed from portion 8 and is adhered to adhesive tape 13.

Another embodiment of the composite film 3 shown in FIG. 5 has the same structure as the composite film 3 shown in FIG.
A cut 10 formed in a part of the periphery of the removal start part 9 of
It is formed by penetrating the upper two layers of the uniaxially stretched synthetic resin film 2 and the reinforcing film 5 without penetrating all the layers of the composite film 3.

The content of this invention is for sweets such as candy and for cleaning.

This is applied to filling wiping paper for face washing, etc., and when the knob 14 of the adhesive tape 13 is picked and peeled off by pulling the knob 140 in the opposite direction, the periphery of the adhesive tape 130 is peeled off from the bag-like container 6. The removal starting part 9 is adhered to the adhesive 12 of the adhesive tape 13 by the cut 10 formed in a part of the periphery of the removal starting part 9, and is removed by the composite film 3). are cut from both sides of the removal start part 9 along the stretching direction B of the uniaxially stretched synthetic resin film to form an open lower part, and the cut removed part 15 is adhered to the adhesive 12 of the adhesive tape 13 and removed to form an open lower part. This is to take out the contents from the lower part.

In the present invention, a tongue-shaped removal section 8 is formed on one surface of a bag-like container 6 made of a composite film 3 having a heat-adhesive synthetic resin layer 1 on the inner surface, and a tongue-shaped removal section 8 is formed to form an opening lower part for taking out the contents. This is a packaging container characterized in that a linear or broken cut line 10 is formed on the periphery of a removal start part 9 of a part 8 to be removed, and an adhesive tube 13 is coated and pasted on the part 8 to be removed. By peeling off the adhesive tape 13 that is adhered to one side of the body of the bag-shaped container 6, the portion 8 of the composite film 3 forming the bag-shaped container 6 to be removed is cut and removed from the side of the removal starting portion 9 to open the lower part. The contents can be taken out from this opening lower, and after taking out the contents, apply the adhesive tape 1 again.
The composite film 3 is obtained by bonding the composite film 3 and sealing the open lower part, and the uniaxially stretched synthetic resin film 2 constituting the composite film 3.
By matching the orientation direction B of the adhesive tape 13 with the peeling direction C of the adhesive tape 13, the composite film 3 can be easily cut along both sides of the notch 10 formed at a part of the periphery of the removal starting part 9.
It is possible to easily form an open lower part by removing the part 8 to be removed, and furthermore, by layering an air-proof film 4 such as aluminum foil on the composite film 3, the aroma of the contents is prevented from volatilizing. It is something that can be done.
