bag body

Abstract

This invention aims to provide a bag that, through simple operation, can stably and easily hold a container, and significantly reduces the likelihood of liquid wetting the bag even if the beverage leaks from the container. The bag has a body with a bottom and a peripheral wall portion connected to the bottom at its periphery. The body forms a space surrounded by the bottom and the peripheral wall portion that can accommodate contents, and an opening for inserting the contents into the space. The body is provided with a position limiting member having a limiting wall portion to restrict movement of the contents within the space. The position limiting member is at least engaged with the inner surface of the peripheral wall portion. When the contents are positioned in the space portion such that movement is restricted by the limiting wall portion, if the surface of the limiting wall portion facing the contents is designated as an opposing surface, the limiting wall portion can be configured to have a first shape state where the opposing surface is concave and a second shape state where the opposing surface is convex.
