Description

[Detailed Description of the Invention] [Industrial field of application] The present invention is a bag made of a plastic film, the opening portion of which is reinforced, and the hole provided in the opening portion is hung with a hook or the like and is hung in the opened state. It is about a bag that can hold things.

[Prior Art] A conventionally used bag made of a plastic film has a rectangular side with one side opened, and a thin plastic film is generally used to form the bag in order to reduce the cost.

[Problems to be solved by the invention] As described above, the thin plastic film bag has low strength and is liable to tear. When putting a normal item, put the bag on the table or the like with the mouth open and put the bag by hand. I put it while supporting it, but it was difficult to even support it because the bag was not stiff, and it was very difficult to put it in because the opened mouth did not have shape retention.

For this reason, the opening of the bag is supported by a frame, and in the case of a garbage bag or the like used in a sink or the like, dust is put in by expanding the bag along the inner surface of the basket or the like placed in a corner.

However, even when the bag is not used, the frame always takes up space and becomes an obstacle, and in the case of the garbage bag, a part of the water discharged from the garbage and the like remains between the bottom and the support,
There were problems such as unsanitary conditions, and it was troublesome to attach the bag to the frame and basket in both cases.

An object of the present invention is to have a strength capable of suspending and supporting an object in a state where the bag is opened and not having a large difference in cost.

[Means for Solving the Problems] In order to achieve the above object, the bag 1 according to the present invention has a plastic film 1a, 1a 'which is folded back and overlaps with each other. The plastic films 1a, 1a 'are folded back again, and both side edges of the overlapped plastic films 1a, 1a' are welded to each other to form inwardly folded pieces 1b, 1b 'in the opening 1'. In the bag 1, which is configured, the folding edges 1c, 1c 'of the opening 1'of the bag 1 are cut out along the folding edge, and the plastic films 1a, 1a' on the front and back sides of the bag are formed. Two or more holes 2 and 3 communicating with the folding pieces 1b and 1b 'are provided.

[Operation] In the bag 1 thus configured, the plastic film forming the opening 1'is formed into two layers by the films 1a and 1a 'and the folding pieces 1b and 1b' which form the bag 1 on both front and back sides. Since the folded pieces 1b and 1b 'have side edges which are the plastic films 1a and 1a' on the front and back sides at the time of welding 6 on both side edges of the bag 1, the opening 1'is reinforced. Back side plastic film 1 of opening 1 '
It is possible to insert a hook or the like through the holes 2 and 3 of the three-layer plastic film of the a'and the folded piece 1b 'and the folded piece 1b of the front plastic film 1a and hang it.

[Embodiment] An embodiment of the bag of the present invention will be described below with reference to the drawings.

Reference numeral 1 is a rectangular bag made of a plastic film such as polyethylene, polypropylene, vinyl chloride, etc. This bag 1 is made by folding one plastic film and stacking the plastic films 1a, 1a 'on both sides so that both side edges are It is formed by welding 6 with a welder or the like.

The bottom portion 1 "is provided with a gusset portion 4 which is folded inward and is welded 6 on both side edges together with the front and back plastic films 1a and 1a '. In the bag 1 of this embodiment, it is used as a kitchen waste bag. The bottom part 1 ″ is provided with holes 5 for venting water and air. Further, in the opening 1'of the bag 1, the plastic films 1a, 1a 'on the front and back are folded back inward, and both side edges of the folded pieces 1b, 1b' are welded 6 together with the plastic films 1a, 1a 'on the front and back. Along the folding edge including most of the folding edges 1c and 1c ', and the folding edge 1c,
Due to the notch 1d that leaves both side edges of 1c ', the folding pieces 1b, 1b' are left between the plastic films 1a, 1a 'on the front and back of the opening 1'in a two-leaf strip shape along the opening 1'.

Reference numeral 2 is a hole that penetrates through the plastic films 1a and 1a 'on the front and back and is inserted into a hanging tool that is opened at a position along the cutouts 1d near both side edges of the opening 1'. A hole 3 is also formed in 1b 'so as to communicate with the hole 2.

This bag 1 has two folded pieces 1b, 1b of the opening 1 '.
The b'and the holes 3 and 2 of the back side plastic film 1a 'are inserted through a hook 7 protruding from a wall surface or the like to be suspended, and the front side plastic film 1a is used by pulling the opening toward the front side. When it is used as a garbage bag, the bottom of the bag is attached to the inner wall surface of the sink so that it floats from the inner bottom of the sink and the water dripping from the garbage flows out through the hole 5 of the bag 1.
No water collects between the bottom of the bag 1 and the inner bottom surface of the sink,
Can drain enough water.

[Effect] The bag according to the present invention is a bag made of a plastic film, and the opening and the back of the bag have the plastic films folded inwardly, and both side edges of the folded piece are the bags. While being welded together with the plastic film on the front and back, and the folded piece is left in the shape of a two-leaf strip between the plastic film on the front and back of the opening by the notch along the opening edge including the folded edge of the plastic film on the front and back, The folded piece is provided with a hole that is inserted into the through hole of the plastic film on the front and back sides, and a strip-shaped plastic whose both edges are welded together with the plastic film on the front and back sides forming the bag at the opening of the bag. Since the film is provided in two leaves, the opening is reinforced and there is no fear that the bag will be torn from the opening.

Also, the opening is made of a four-leaf film by combining the front and back plastic films, and it is possible to hang it on a wall etc. by inserting a hole of the two-leaf or three-leaf film into a hook and insert an object. It is convenient and does not require a frame to support the bag in the open state to put things in the bag as in the past, and it makes a hole in the bottom of the bag and floats it from the inner bottom surface of the sink as a garbage bag of the sink. When used, it is hygienic because water from the waste easily flows out.

Also, since the band-shaped plastic film at the opening can be held as a handle when holding the bag, it is convenient to carry.

Further, the cost of this bag is low, which is not so different from the conventional bag because of its structure.
