Abstract: A spill resistant lid to be secured over the open top of a container to resist spilling of the container contents from the open top of the container includes a central lid portion extending over the open top of the container. A raised portion, such as a drinking mouthpiece, extends above the central lid portion and a deformable section, such as a cylindrical section, extends downwardly from the raised portion toward the central lid portion. The deformable section is at least partially separable from the central lid portion so it can be deformed in an over center manner or other manner such that deformation of the deformable section toward the raised portion results in the deformable section assuming a stable open position exposing an opening or hole through the lid into the container and deformation of the deformable section from open position results in the deformable section assuming a stable closed position over the opening or hole.

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.
