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.
