Description

The present invention relates to a packaging bag.

Hygiene products such as toilet rolls, tissue paper, sanitary products, disposable diapers, and wipes are usually sold in a single package because of their high consumption rate. For example, 4R (roll), 8R, 12R for toilet rolls, 3B (box), 5B for tissue paper, 2P (piece) for sanitary napkins and disposable diapers, and 3P, 8P, 10P for wipes are commercially available. In recent years, the number of products with a larger quantity of contents has increased. For example, there are products such as 18R and 30R for toilet rolls and products with increased winding length per roll, and the number of products with heavy weight per product has increased. It's coming. These products have the advantage that a large amount of contents can be purchased with one purchase, and once purchased, there is no need to purchase for a while.

However, one of the disadvantages when shopping for these products is the load on the hands when moving a heavy product by hand. This is because products are usually carried by hanging them on either of the hands, which increases the pressure on the palm or fingers. Furthermore, if one product is heavy and the volume is large, the product tends to close hands and it becomes difficult to carry other shopping bags, so the purchaser should presume the weight or capacity of the product at the time of purchase. There was also the problem of having to keep it to a minimum. On the other hand, in recent years, the elderly in Japan have a declining birthrate and an aging population, and the physical strength of minors or elderly purchasers is relatively weak. Therefore, there has been a demand for a transportation form that can be carried more easily if possible. Under such circumstances, various solutions have been proposed for carrying the product on the shoulder other than the hand or carrying it on the back.

For example, in Patent Document 1, both ends of the tape member are adhered to each other on the square end surfaces of the main body portion, the portion other than the bonded portion is not adhered to the outer surface of the main body portion, and the free portion thereof is the main body portion. A package is disclosed characterized in that it is longer than the length of the shortest path along the outer surface.
Further, Patent Document 2 discloses a package characterized in that a part or the whole of the free portion described in Patent Document 1 is temporarily fixed to the outer surface of the main body portion so as to be peelable.
