Problems solved by technology

In such a packaging bag with a check valve function, if the content decreases, the internal volume will also decrease because air does not enter from the outside, and accordingly, the horizontally opposite surfaces of the film forming the main body will shrink. Narrow and close-fitting, it is more difficult to maintain self-support than bags without check valve function

Abstract

The self-standing packaging bag with a spout has a bottom section formed from a bottom member that is half folded along a fold line and that is attached to the lower inside of a trunk section such that the fold line faces upward, wherein the extending direction of the fold line of the bottom section and the closing direction of the upper end in the trunk section cross each other on a horizontal projection plane, and in a state in which side end portions of two regions of the bottom member which are separated by the fold line overlap each other, the bottom section is joined in a planar manner to an inside section of the trunk section.

Description

technical field [0001] The present invention relates to a self-supporting packaging bag with a mouth. [0002] This application claims priority based on Japanese Patent Application No. 2018-017413 for which it applied to Japan on February 2, 2018, and uses the content here. Background technique [0003] As a pouch made of a flexible packaging material such as a plastic film, a pouch having self-standing properties, that is, a stand-up pouch (stand-up pouch) is known. As a self-supporting packaging bag, there is known a packaging bag formed by inserting a bottom member folded in half forming the bottom into the lower part of the cylindrical main body with its folding line upward, and in this state, utilizing the The side ends of the bottom member are sandwiched between the side ends, and they are heat-sealed, and their lower ends are heat-sealed to each other over the entire circumference, thereby forming a packaging bag. In such a conventional self-standing packaging bag, ...
