Description

Detailed description of the invention

This device is used for product display so that bulky three-dimensional contents such as various underwear, soap, lunch boxes, cups, cassette tapes, electronic parts, etc. are packed into the bag almost completely. The present invention relates to a product packaging bag made of a plastic film that facilitates the insertion of products.

Conventionally, in the case of product packaging bags made of plastic film in which bulky three-dimensional contents such as soap and lunch boxes are almost fully packed inside the bag for product display, the upper gusset part In the case of a bag made of a plastic film having the shape, there is a type in which a three-dimensional content is put from the lower part thereof. (For example, see Patent Document 1)
In addition, there is a case in which a three-dimensional content enters the inside of the bag body from above the bag body, and an upper opening portion without a gusset portion is provided at a position near the lower edge of the header. (For example, see Patent Document 2)

Problems to be solved by the device

However, in Patent Document 1, since the three-dimensional contents that are bulky are inserted from below, even if the lower part is closed with adhesive tape, buttons, or hooks, these locking tools are used. There is always a risk of the contents falling if is not fully functional. Furthermore, apart from the production work of the bag body, an operation of mounting the above-described locking tool is necessary, and the cost is unavoidable.

Moreover, in what is shown to patent document 2, the width of a header part is smaller than the width of a lower bag body, and what is called a shoulder fall type plastic film product packaging bag has a three-dimensional content from the upper part inside a bag body. In the product packaging bag, in the plastic film product packaging bag in which the upper opening is close to the upper header and the opening is formed, since there is no upper gusset portion, when placing a three-dimensional product, Since there is no large opening, it tends to be extremely difficult to put a three-dimensional container.
Even if a three-dimensional container enters from the opening, both ends of the opening are strongly pulled, and there is a risk that the product packaging bag is damaged from both ends of the opening.

Therefore, the object of the present invention is to easily put bulky three-dimensional contents, and after putting the three-dimensional contents, it can be accommodated as the shape and there is no risk of dropping. An object of the present invention is to provide a product packaging bag made of a plastic film that can make the production cost of a product packaging bag extremely low and that does not have the above-mentioned drawbacks.

Means for solving the problem

In view of the above problems, the present invention is a product packaging bag made up of an upper header and a film bag suspended from the lower portion of the upper header, and the film bag has a bottom gusset at the bottom, An upper gusset portion is formed on both sides of the inclined fusing portion formed on both sides of the upper portion of the film bag body, and a suspension piece formed on the central portion of the thickness of the upper gusset portion and the upper header are continuously provided. A lid film was extended from one side of the hanging piece to make a product packaging bag made of plastic film.

Furthermore, the upper and bottom of the product packaging bag made of plastic film, and an upper gusset portion formed respectively, bottom Gazette, there is almost uniformly form the thickness.

The plastic film product packaging bag a of the present invention comprises an upper header 1 and a plastic film bag body 5. The upper header 1 has a plastic plate or paper plate as a core material 2 and is covered with a plastic film, and a retaining hole 3 is formed at the center of the lateral width. A plastic film bag body 5 suspended from a suspension piece 4 provided at the lower portion of the upper header 1 is provided continuously.

In FIG. 1, the width of the film bag body 5 is made larger than the width of the upper header 1, and the lower end portion of the upper header and the upper end portion of the film bag body 5 are melted to end the upper header 1. A product packaging bag a made of a so-called shoulder drop type plastic film, which forms welded inclined side edges 6, 6 extending downward toward the lateral width end of the film bag body 5, is shown. .

The film bag body 5 made of plastic film is provided with bottom gusset portions 7 and 7 at the bottom, and upper gussets on the welded inclined side edges 6 and 6 formed on both upper side portions of the film bag body 5. The lower portion of the upper header 1 and the film bag body 5 made of a plastic film are connected via a suspension piece 4 at the center of the upper gusset portions 8 and 8. It is a certain thing. Moreover, the thickness of the bottom gusset portions 7 and 7 and the thickness of the upper gusset portions 8 and 8 are substantially the same width. The above-described gusset portion is usually referred to as a gusset portion, and is a curved portion for increasing the volume inside a paper, plastic, cloth or leather bag.

The boundary between the upper header 1 and the suspension piece 4 is connected by a welded portion 13, and the suspension piece 4 is constituted by a two-layer plastic film, and one side of the suspension piece 4 is a film bag made of a plastic film layer. While continuing to the back of the body 5, the other side of the hanging piece 4 is continuously extended to the lid film 9.

An opening 10 is formed only on one side slightly below the lower end 7 of the welding inclined side edges 6 and 6 of the film bag body 5 made of plastic film, and the lower ends 7 of the welding inclined side edges 6 and 6 are formed. Further, the lid film 9 is extended so as to cover the opening 10 on one side and a slightly lower part of the opening 10 on one side. The lid film 9 has a strip-like adhesive layer 13 formed on the inner side surface of the lid film 9 over almost the entire length in the width direction. The adhesive layer 11 provided on the lid film 9 is adhered to the lower part of the opening 10 of the film to seal the opening 10.

In order to simplify the bonding operation of the adhesive layer 11 formed on the inner side of the lid film 9 at the time of bagging the product, the release tape 12 of the adhesive layer 11 is temporarily fixed in a peelable manner. The operator puts the release tape 12 while pulling the lid film 9 provided inside the lid film 9 slightly downward after putting the three-dimensional product b in the plastic bag 5 made of plastic film. By simply peeling off, the sealing operation of the film bag body 5 made of plastic film is completed.

When placing the three-dimensional product b into the plastic film bag body 5, the plastic film product packaging bag of the present invention can open the upper gusset widely, so that the product bagging operation is extremely quick and It will be simplified.

As described above, the upper gusset portions 8 and 8 and the bottom gussets 7 and 7 respectively formed on the upper and bottom portions are formed to have substantially uniform widths. When the three-dimensional product b is inserted, the outer shape of the plastic bag 5 made of plastic film does not lose its shape, and the three-dimensional product b can be seen as it is.

Effect of device

In the product bag made of plastic film, in the product packaging bag made up of the upper header and the film bag suspended from the lower part of the upper header, the film bag is provided with a bottom gusset at the bottom and made of film. Since the upper gusset part is formed on both sides of the inclined fusing part formed on the both sides of the upper part of the bag body, and the suspension piece formed in the central part of the thickness of the upper gusset part and the upper header are connected continuously, Since the upper gusset portion and the bottom gusset are formed on the bottom and the bottom, respectively, it is possible to speed up the work of bagging the three-dimensional product, and the width of the upper gusset portion 9 and the bottom gusset is substantially equal. Therefore, the film bag body made of plastic film can store the product inside without distortion. It is easy to put three-dimensional goods, and after putting three-dimensional goods, it can be stored as the shape, there is no risk of dropping, and the cost of creating product packaging bags can be extremely low In addition, a product packaging bag suitable for hanging sales and shelf sales at the time of exhibition and display is provided.
