BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a drainage bag for use in a kitchen or the like, and a device for closing an opening of a water-permeable or air-permeable bag for packaging foods and the like.

[0002]

2. Description of the Related Art Drainage bags and the like used in conventional kitchens are made of net or porous film, or stretched plastic non-woven cloth, and are used as garbage bags containing water in the kitchen. Although a bag having water permeability was used, when dust and the like were accumulated in the bag, the bag was thrown into the trash box.

When packaging foods or the like that require air permeability, since the opening has an opening at the top to prevent the contents from spilling out, store them separately with a cord or a clip. It was necessary to bind the opening with.

[0004]

Therefore, first of all, as for a drainage bag for a kitchen or the like, when dust or the like is accumulated in the bag, the bag has an opening at the top so that the bag can be thrown into the trash can. Therefore, it has a drawback that dust, which is the content, spills from here. In addition, when throwing the drainage bag from the triangular corner of the kitchen into the trash can, it is extremely troublesome to separately use a string or the like to close the opening.

When packaging food or the like that requires air permeability, it is easy to take in and out the contents because it has an opening at the top, but keep the half contents so that they do not spill outside. It was necessary to separately bind the opening with a string or a clip.

Particularly when tying the cord or the like, not only is it extremely time-consuming, but it is more difficult to tie the openings so that the contents do not come out tightly as the contents increase.

[0007]

Means for Solving the Problems The present invention is to solve the above problems and provides a bag of a thermoplastic film having breathability or water permeability, or a non-woven mesh or a thermoplastic film made of a woven mesh. Along the edge of the opening inside the bag of the bag , a non-stretchable tape having an adhesive surface on one surface is attached, and both side edges of the bag together with the non-stretchable tape are subjected to polymerization heat. This can be solved by the welding and closing of the opening inside the bag of the bag in which a notch is provided at the edge of the opening of the bag .

[0008]

With this structure, the non-stretchable tape adhered along the edge of the bag inside opening of the bag with the contents inside the bag is The portion exposed by the notch of the bag can be peeled off from the edge of the bag, the opening of the bag can be gathered, and the tape can be wrapped around the outer circumference. Since this tape has an adhesive surface on one side, it can be closed with the opening closed. By this
The tape wraps around the opening of the bag, which is

Embodiments of the present invention will be described in detail below with reference to the drawings. FIG. 1 is a perspective view showing an embodiment according to the present invention, in which 1 is a bag made of a thermoplastic film having air permeability or water permeability, and a fold 2 is formed in a bag 1 to form a bottom portion 3. It is a bag body 1 made by folding the film in two by folding it into two. The length between the fold 2 and the bottom part 3 can be any length as long as it is within the total length of the product,
A bottom bag part in the form of a gusset is formed.

The bag 1 made of a breathable or water-permeable thermoplastic film has an opening 6 and extends along an edge 7 inside the bag on one surface of the bag constituting the bag. Then, the non-stretchable tape 10 having the adhesive surface 9 is attached to one surface thereof.
In this case, the adhesive surface 9 of the tape 10 is attached to the surface of the film forming the bag body 1.

Therefore, since the non-stretchable tape 10 is adhered to the edge portion 7 inside the bag body 1, the surface of the non-stretchable tape 10 having no adhesive surface is inside the bag body 1. The opening 6 of the bag 1 is not attached because it is in contact with the surface facing the edge portion 7, and the opening 6 can be freely opened. In addition, the non-stretchable tape 10 is attached to the surface of the bag body.
Instead of sticking it to the film surface where it is located,
Since it is attached to the film surface located inside, it is a bag
When carrying or storing your body, this tape may be
It does not come off from the bag. Non-stretchable tape 10
May have adhesive surfaces 9 on both sides thereof, in which case the opening 6 can be closed.

In order to form the bottom part 3 of a thermoplastic film having air permeability or water permeability, the folds 2 are folded in two in the bag 1 and the side edges 4a, 4b thereof are formed.
And heat-welding the other side edge portions 5a, 5b. Therefore, in this case, the heat-welded side edges 4a, 4b and the side edge 5 are
Since both end portions of the non-stretchable tape 10 are adhered to the edge portion 7 inside the bag body 1 of each of a and 5b, this portion is polymerized and heat welded.

A notch 11 is provided at the edge of the side of the seal portion where the side edges 4a and 4b are heat-welded. Therefore, in this notch 11,
The non-stretchable tape 10 is laid over the notch 11, and the tape 10 is exposed on the outer surface. It should be noted that the slit 12 may be provided in the portion of the tape 10 exposed from the cutout portion 11. This makes it easier to pick the tape 10 by hand and
Make it easy to peel it from the bag body 1.

FIG. 2 is a view showing a state in which the non-stretchable tape 10 is peeled off from the edge portion 7 inside the bag body 1, and the cutout portion is shown.
If you pick the part that is exposed on the outer surface from 11 and pull it lightly,
The non-stretchable tape 10 is peeled off from the edge portion 7 inside the bag body 1.

The other end of the non-stretchable tape 10 has a bag body.
Since it is heat-welded with the side edge portions 5a and 5b of 1, it cannot be peeled off from the seal portion of the side edge portion of the bag body 1,
As a result, one end of the non-stretchable tape 10 is locked to the bag body 1. Since the non-stretchable tape 10 has the adhesive surface 9 on one surface, the tape is adhered to the one adhesive surface 9 of the non-stretchable tape 10 even when it is peeled off from the bag body 1. It has a sex.

FIG. 3 is a view showing a state in which contents are contained in the bag body 1 according to the present invention. In this case, the contents are packed in the bag body 1.
It is in a state in which the opening 6 is squeezed in the lower part, and the non-stretchable tape 10 is wound around the outer periphery of this sizing part.

Since this non-stretchable tape 10 is locked at the side edge 5 of the opening 6 of the bag 1 inside the bag 1, the opening 6 is gathered and bound. Even if the one end of the non-stretchable tape 10 is locked, the non-stretchable tape 10 can be wound around the outer circumference of the portion where the opening 6 is put together, and the non-stretchable tape 10 is attached to the wound portion by the adhesive surface 9. To wear. In particular, this non-stretchable tape 1
