Abstract:

A cover for drinking containers, and which includes a generally flat, circular disk-shaped body having two laterally projecting seal flanges. A firm body portion is sized smaller than the interior diameter of an applicable drinking container while the outward projecting annular seal flanges extend to make the overall body slightly larger in diameter than the interior diameter of the drinking container to serve as fluid seals and as frictionally adhesive members which engage the interior sidewall of the container to assist in stabilizing the cover. The top surface of the body is affixed with two oppositely disposed outward projecting flexible extending arms which extend outward beyond the sealing flanges. The arms each support a terminal end stop hook. When the cover is inserted into the open top end of a drinking container, the arms are folded upward, the folding being the result of the arms engaging the top interior lip of the drinking container, and being bent upward as the body with peripheral flanges is moved downward into the container.
