1 (a) is a plan view of an embodiment of the product packaging bag of the present invention, and FIG. 1 (b) is an end view of a cut portion thereof. The product packaging bag of the present invention comprises a lower bag body 1, an upper bag body 2 and a header portion 3. In FIG. 1A, the alternate long and short dash line indicates the positions of the lower ends of the lower bag and the upper bag.
The lower bag body is composed of a front surface film 4 and a back surface film 5, has a depth over the entire size of the product packaging bag excluding the header portion, and a product insertion port 6 is provided at the lower end of the lower bag body. The upper bag is composed of an upper bag front film 7 and an upper bag rear film 8 that are stacked between a front film and a back film, has a depth smaller than that of the lower bag, and is located at the upper end of the upper bag. A product slot 9 is provided. The header portion comprises a header sheet 12 sandwiched between an extension portion 10 of the surface film and an extension portion 11 of the upper bag front surface film, and the extension portion of the surface film and the extension of the header sheet and the upper bag body front film. The parts are fused together at the fusion line 13. In addition, a hanging hole 14 is formed in the header portion. In the product packaging bag, the lower bag has both side edges, the upper bag has both side edges, and the header has both side edges.
It is thermally fused at 5. The product packaging bag of the present invention,
Since it is divided into a lower bag and an upper bag and each has an independent product insertion port, it is possible to separately store two articles. In the upper bag body, since the four films, that is, the front surface film, the upper bag body front surface film, the upper bag body rear surface film, and the back surface film are fixed on both side edges by thermal fusing, the shape retention is good. Therefore, for example, even if a relatively heavy article is stored in the upper bag, the upper bag does not deform and sag. For this reason, when the products are stored in the lower bag body and the upper bag body, it looks good, and it is possible to display the product in a store with a beautiful appearance.

Since the lower bag body of the product packaging bag of the present invention has a depth that covers the entire size of the product packaging bag, for example, a small product is stored in the upper bag body and the entire surface of the product packaging bag is in the lower bag body. Items such as instruction manuals and warranty cards of the same size as can be stored. In addition, in a warranty card, etc., in a store, the date of sale and the name of the store are often entered and affixed, but since the product packaging bag of the present invention has a lower bag body and an upper product body with independent product insertion ports, Without touching the stored product, you can take out the warranty card, fill out the necessary items, and then put it in the product packaging bag again.
In the product packaging bag of the present invention, the upper bag has a smaller depth than the lower bag, but the depth can be arbitrarily selected according to the articles to be stored. For example, if you store the product in the upper bag and the instruction manual in the lower bag, you can select the depth of the upper bag so that the product is located in the center of the product packaging bag. When storing the same product in the lower bag, the depth of the upper bag and the depth of the part of the lower bag that does not overlap the upper bag can be the same size. When storing a large product in the bag, the depth of the lower bag that does not overlap the upper bag can be made larger than the depth of the upper bag. The product packaging bag of the present invention can be used as a mere design space without storing the product in the lower bag body while storing the product only in the upper bag body. In such a usage method, the product stored in the upper bag is fixed in a state of floating in the hollow, and is effective for a product that requires a large display space for the size of the product, for example. Exert. In this case, the lower end of the lower bag that does not store the product can be sealed in advance by fusion or the like.

In the product packaging bag of the present invention, opaque printing can be applied to the film so that the articles contained in the lower bag or the upper bag cannot be seen. For example, when a product packaging bag stores products such as toys and confectionery and bonuses and does not want to show the bonuses, conventionally, a paper box has been divided into two or enclosed. According to the product packaging bag of the present invention, for example, opaque printing is applied to the upper bag front film and the upper bag rear film, the lower bag body stores the product, and the upper bag body stores the bonus. Can be reached When packing two different products, such as a stationery set that combines a pencil and an eraser, it may be necessary to enclose the products in another factory.
In such a case, if the product packaging bag of the present invention is used, after the product is enclosed in one of the lower bag body and the upper bag body and then transferred to another factory, it is reopened when another product is enclosed. No need. Moreover, since the completely independent insertion port is used for enclosing the product, the other product does not interfere with the encapsulation. As shown in FIG. 1, the product packaging bag of the present invention can be composed of a continuous film of a surface film, an upper bag front film, an upper bag rear film, and a back film. By constructing the front surface film, the upper bag front film, the upper bag rear film and the back film from one continuous film, there is no need to cut and overlap the films forming each bag, which is economical. The product packaging bag of the present invention can be manufactured.
