摘要：The present invention is an airtight canister. The airtight canister comprises a ceramic container and an acrylic cover. The ceramic container has an open top, a bottom and an annular groove adjacent to the bottom. The acrylic cover is secured on the ceramic container by an elongated cord and a wave-shaped hook. The elongated cord has two ends interconnected by a coil spring which creates a tension on the cord, and the hook is linked to the cord between its two ends. A generally " pi "-shaped member is mounted on the cover and has an inner chamber for retaining the coil spring and the two ends of the elongated cord. When the cover is placed onto the open top of the container and the hook is retained by the annular groove adjacent to the bottom of the container, the tension on the cord created by the coil spring will remain a pressure on the cover through the connecting member, which in turn creates an airtight coverage.
