摘要： 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.

摘要： The present invention relates to a vacuum means for storage bags which comprises an air exhaustion opening and an air exhaustion valve, both of which are disposed on an outer surface of the storage bag; the air exhaustion opening and the air exhaustion valve are interconnected; the air exhaustion valve comprises two or more layers of soft sealing plates, and the layers of soft sealing plates overlap with one another and their edges are connected with the storage bag in a sealed manner; ventilation openings separated from one another are opened on each of the two or more layers of soft sealing plates, and each of the two or more layers of soft sealing plates are interconnected with the air exhaustion opening at areas where the ventilating openings are opened. The air exhaustion valve of the present invention mainly attains sealing effect by adhering the soft sealing plates with one another. As the soft sealing plates are softer and more resilient, it is easier for them to resume their original shapes. It is also easier for them to adhere to one another without leaving any space in between. Therefore, in comparison with existing vacuum means which attains vacuum by adhering hard material to soft material, the present invention has a better sealing effect and maintains vacuum for a longer period of time. Besides, as the costs of raw materials are lower and the manufacturing process is simpler, the costs of the present invention are lower and so the present invention has more significant economic benefits. The present invention is widely applicable to various forms of existing storage bags and so has a higher adaptability. Besides, in comparison with existing vacuum means which attains vacuum by applying adhesives to adhere the soft sealing plates to one another, the present invention attains sealing effect without the need of any adhesives. Therefore, the sealing effect would not be affected due to weakening of adhesive power of the adhesives, and the soft sealing plates would not be unable to separate from one another as they are adhered to each other for a long time.
