Description

[Detailed explanation of the idea] [Industrial application field]

The present invention relates to a packaging bag.

[Prior art and its problems]

Bags are used for packaging various items. A conventional packaging bag has the following structure. That is, fold-in portions that are folded inward are provided on both sides in the vertical direction, and a sealed portion is formed at the lower end by welding or the like. The upper part of the packaging bag is open and is folded inward by a predetermined width to form an attachment part. A handle is attached to the attachment part. This conventional packaging bag has the following problems. (1) Since the seal of the packaging bag is located at the bottom of the bag, the weight of the contents is directly applied to the seal. Therefore, if the welding is incomplete, there is a risk of the container falling out when a heavy object such as a can containing a beverage is stored. (2) There is nothing in the opening that functions as a lid, and the contents inside the bag are covered with dust. By the way, Japanese Utility Model Publication No. 51-143620 discloses a cassette fold-in part, which is provided by folding the bottom of the cylindrical synthetic resin bag body inward, and welded parts, which are provided at both left and right ends. A storage bag is disclosed. Since this storage bag has the above-mentioned structure, it can solve the problem of the bottom falling out, but it has the following problem. That is, in the storage bag, a notch is provided in the upper edge of the bag body to simultaneously form an opening and a string-like body, and the string-like body is pulled to close the opening and package the contents. There is. In this case, as is clear from Figure 8 of the same publication, in order to close the opening, not only many wrinkles are formed on the side wall of the bag body;
The shape also changes. For this reason, it cannot be used to package products that make the product look good and promote sales, such as canned soft drinks or canned beer. In addition, in Japanese Utility Model Publication No. 54-70711, inward from the top four sides of a rectangular bag made of thin paper,
A carrier bag is disclosed that has extended lid pieces having different lengths and bending points. Although this carrier bag has the above-mentioned structure, it can solve the problems such as the contents being covered with dust, but it has the following problem. In other words, the carrier bag is made by folding thin paper.
Since the bending points also vary in a complicated manner, manufacturing requires a complicated bending process, leading to an increase in manufacturing costs. Furthermore, there is an order in which the lid pieces are stacked, and it takes time to package the contents. The lid will actually open if you don't put a further seal on it. Furthermore, when storing a plurality of bottles, the lid piece becomes longer together with the bag body, and the portion to be removed during molding becomes larger, resulting in wasted material.

[Purpose of this invention]

Therefore, an object of the present invention is to provide a packaging bag that can accommodate items with good appearance. Another object of the present invention is to provide a packaging bag that is easy to process and does not waste material.

[Configuration of the present invention]
