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. | 10-20-2011 |
