Description

  The present invention relates to a hand-held shopping bag for storing and taking back a product after clearing, for example, at a supermarket or a convenience store. More specifically, the hand-held portion of a used shopping bag can be expanded and restored very easily. The present invention relates to a shopping bag that is characterized in that the bag can be folded into a compact sheet.

The shopping bag was created to prevent shoplifting for the store and to allow the consumer to easily take the product home. For example, as disclosed in Patent Document 1 or Patent Document 2, a synthetic resin thin film such as polyethylene is used as a material, and the upper end edge on the left and right sides of the bottomed bag body opened upward is provided between the opposing upper end edges. It is common to have a pair of left and right handbags erected. In the conventional shopping bag, a cylindrical synthetic resin thin piece is cut into a predetermined length in the length direction, and then the left and right sides of the cylindrical synthetic resin thin piece are folded inward, and the inner surface is closely contacted and folded in two. The bottom edge is closed by heat-sealing to form a bottomed bag body with gussets on the left and right sides, and the upper part is cut into a rectangular shape with the central part cut into a product entrance. A pair of handbag pieces that overlap vertically with the J-shaped cut edge and the cut edge of the product entrance are provided on the left and right sides, and the upper edge of the handpiece piece that overlaps vertically is connected by heat seal processing to form a pair Is formed by bridging the upper end of the bottomed bag body. The heat seal part at the upper end of the hand-carrying part needs to have a connection strength that does not cause the plastic bag containing the product to peel off due to the weight of the product, so it is formed in a narrow strip that extends in the horizontal direction with a vertical width of about 3 mm. Has been. In the conventional shopping bag having such a configuration, after use, a large number of vertical hooks are formed around the heat seal portion in the hand-held portion by the weight of the product, and the hand-held portion becomes a string shape substantially in proportion to the weight of the stored product. .
By the way, in recent years, from the viewpoint of environmental problems such as fossil fuel consumption reduction and garbage problems, local governments are moving toward enacting regulations to charge plastic bags or prohibit the use of plastic bags at stores. Currently. In order to follow this ordinance, when the conventional general shopping bag is folded into a sheet-like compact shape that can be stored in a bill holder or the like for the purpose of reuse after use, it is formed in the heat seal part. There is a need to stretch a lot of downpipe. In order to level the hand-held part, this heel-stretching work has to be time-consuming and cumbersome because it is necessary to squeeze the finger in the lateral direction several times in the vicinity of the heat-seal part and the vicinity of the heat-seal part. There was a point.

  The present invention was devised in view of the above-mentioned circumstances. By making the length of the heat seal part formed at the upper end of the handbag part a certain length or more, the heat seal part has hardness and is It is an object of the present invention to provide a shopping bag that can significantly improve the lengthening operation of the vertical hook by significantly reducing the amount of formation and having the heat seal portion have a fixed form retaining ability.

  The invention according to claim 1 of the present invention is a shopping bag provided with a pair of handbags on the left and right sides of the upper edge of the bottomed bag body which is made of a flexible thin piece and opened upward. The upper end portion is characterized in that a heat seal portion having a constant vertical width exceeding 1.5 cm and not exceeding 5.0 cm is provided in a strip shape in the horizontal direction.

The plastic bag of the present invention is provided with a heat seal part having a constant vertical width of more than 5.0 cm and a vertical width of more than 5.0 cm at the upper end of the handbag. There is an effect that it is difficult to form a vertical hook at the upper end portion of the handbag portion that is easily formed.
Also, since the heat seal part is cooled and solidified after the synthetic resin is welded, it has a certain degree of hardness. The sheet is spread in the shape of a sheet, and the work of extending the sheet can be performed very easily, and the subsequent operation of folding the sheet can be easily performed in a short time.

Best mode for carrying out the invention

  The purpose of the handbag is to enable the work of extending the vertical hook at the top of the handbag attached after the use of the plastic bag to be performed in a very short time, and simplifying the work of folding the plastic bag into a sheet in a compact manner. A portion having a hardness higher than that of the other portions is formed at the upper end of the belt by forming a belt having a longitudinal width extending in the horizontal direction of a predetermined width.

1 is a partially cutaway front view of the present invention plastic bag, FIG. 2 is a cross-sectional view taken along line AA of FIG. 1, and FIG. 3 is an explanatory view showing a state in which a plastic bag folded into a sheet is stored in a storage container. is there.
In these figures, the plastic bag 1 is made of a thin piece made of synthetic resin such as polypropylene or polyethylene, and an inverted M-shaped cut edge 4 having a knot 3 at the center is provided at the upper end of the bottomed bag body 2. And form a product doorway. The hand-carrying piece 5 is continuously extended upward from the left and right sides of the upper end of the bottomed bag body 2, and the upper ends of the hand-carrying pieces 5, 5 at the opposite positions are heat-welded and connected by heat sealing. A pair of hand-held portions 7 are formed between the upper ends of the body body 2. The heat seal portion 6 is formed in a strip shape that extends in the lateral direction with a vertical width exceeding 1.5 cm and 5.0 cm or less.

  Next, the operation will be described. The upper ends of the hand-made pieces 5 and 5 made of synthetic resin thin pieces form one continuous hand-made portion 7 by heat-welding and connecting the synthetic resin of the material by heat sealing. That is, since the heat seal part 6 heats and melts the upper ends of the handpieces 5 and 5 and is left at room temperature to cool and solidify the heat radiation, the hardness of the synthetic resin of the heat seal part 6 is increased in a band shape extending in the lateral direction. And is molded integrally, and it is difficult to form wrinkles on the heat seal portion 6. Further, since the heat seal portion 6 is formed in a flat belt shape having a predetermined hardness extending in the lateral direction, even if a vertical fistula is formed on the heat seal portion 6, a slight lateral force is caused by the elastic restoring force of the synthetic resin. It is restored to a flat belt shape by the force in the direction, and the vertical hook formed on the hand-held portion 7 of the used shopping bag 1 can be easily spread, and can be easily folded into a sheet-like compact shape. For example, as shown in FIG. 3, a used plastic bag 1 is compactly folded for reuse and stored in a plastic bag storage container 8 formed in the same shape as a bill compartment. It is possible to carry it on a daily basis, and it is possible to prepare a shopping bag instantly even in unexpected shopping.
