Abstract
Vessel for storing tea or coffeee comprises two connected sections, one of rigid material serving as a handle, and the other as an elastic stopper in the vessel's mouth. The stopper is conical at the bottom and merges into a cylindrical section. The vessel mouth along the inner edge has a slightly smaller diameter than the rest of the vessel's mouth and the cylindrical part of the stopper. Specifically, the stopper section is of high pressure polyethylene and has inner reinforcement ridges.
