Document Type and Number:
WIPO Patent Application WO/2010/090483
Kind Code:
A2
Abstract:
The present invention relates to a vinyl bag with an internal, bendable check valve which enables safe storage of food or the like by discharging air within the vinyl bag to the outside through the check valve, and sealing the inside of the vinyl bag in a vacuum state. The check valve of the present invention comprises: a cover member comprising a pressure bending part that is attached to one side of the vinyl bag, forms a convex protrusion in the opposite direction of the vinyl bag, and is elastically deformed, and a first discharge hole communicating with a hole in the center of the pressure bending part; and an opening-shutting member that is made of an elastic material, is located between one side of the vinyl bag and the cover member inside the pressure bending part, and opens and shuts the gap between the hole and first discharge hole. The opening-shutting member comes into contact with one side of the vinyl bag by vacuum pressure and seals the hole as the vacuum is completed. The pressure bending part is bent downward toward the opening-shutting member by external force, brings the opening-shutting member into contact with one side of the vinyl bag, and fixes the opening-shutting member. The downwardly-bent pressure bending part bends upwardly in the opposite direction of the opening-shutting member by external force and is elastically deformed in the original shape thereof.
