Abstract
A spill resistant lid includes a sealing bead in pressure contact with the inside wall of a container to be closed when the lid is in sealing position with respect to the container to substantially seal the container. The lid includes a first cylindrical wall and a second cylindrical wall spaced apart to form a receiving channel for the top of a container to be sealed. A ridge extends into the channel from the first cylindrical wall to hold the lid in place. The sealing bead extends into the channel from the second cylindrical wall. A central lid portion closes the area inside the second cylindrical wall and applies sealing pressure to the bead. In a preferred embodiment a third cylindrical wall in the central lid portion is joined to the second cylindrical wall by a web. The relative positions of the second cylindrical wall, the web, and the third cylindrical wall are deformed when the lid is in sealing position on the container and such deformation causes the bead to apply sealing pressure to the inside container wall. The central lid portion also preferably includes a container bottom platform and container receiving groove or secondary container platform for receiving and holdi…
