Waterproof storage bag

Abstract

A waterproof storage bag which comprises a bag body having an open end and a bag opening provided at the open end of the bag body to seal the bag body. The bag opening has inner surfaces which are smooth surfaces made of smooth and soft plastic material and the inner surfaces do not contain any self-adhesive material and are not disposed with any additional adhesive material thereon. A multi-porous resilient member is provided inside the bag body. It is an object of the present invention to provide a waterproof bag which could indicate to a user whether its waterproof function is still functioning properly. It has the advantages of simple structure, easy operation and low manufacturing costs.

What is claimed is:
