ABSTRACT:
An airtight canister including (a) a ceramic container having an open top, a bottom and an annular groove adjacent to the bottom; (b) an acrylic cover having an annular rim; (c) an annular rubber gasket wrapped on the annular rim of the cover; (d) an elongated elastic cord having two ends; (e) a wave shaped hook linked to said cord between the two ends; and (f) a generally ".pi."-shaped connecting member connected between the two ends of said cord and said cover; (g) so that 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 of the elastic cord will maintain a pressure on the cover through the connecting member, which in turn creates an airtight coverage with the help of the gasket.
