An airtight container comprising; a cover 1, a container 2, and two airtight members (3, figure 1). The cover has an exhaust part 11 and a releasing part 12. The two airtight members are respectively mounted in the exhaust part and the releasing part of the cover and each airtight member has an inlet 31 and an air gap 32. The air gap communicates with the inlet. Where the inlet of one airtight member opens into the container and the inlet of the other airtight member opens out or the container. Therefore, the container could be sealed or unsealed by pressing the cover to the container or detaching the cover from the container. A second embodiment details the exhaust and releasing parts as one assembling hole, where the two airtight members are connected (figure 15) to form a bi-directional valve. The airtight members may be tapered, where the inlet is cylindrical and the air gap tapers. |
