Abstract

The wall surface of the self-supporting bag-shaped vacuum container of the present invention is formed by a soft board, and has a self-supporting container, a spout, and a one-way valve attached to the spout; When pressure is applied in the direction of filling, it will allow the movement of the contents, and when pressure is applied in the filling direction, it will close, so that the inside of the container becomes a vacuum state. Since the stand-up pouch-shaped self-supporting container of the present invention has the above structure, it can provide a container that is particularly suitable for storing beverages and the like that are oxidized due to the contact of the contents with the air and avoid contact with the air. It is a vacuum-type container that can stably generate self-support without losing self-support even when the contents are reduced.
