Abstract
A liquid container includes a brim forming an opening into a liquid reservoir chamber formed in the cup. A lid is coupled to the brim to form more than one seal with the container. The lid includes lid-removal blocker walls arranged to engage undercuts formed in the cup to retain the lid in a mounted position on the cup closing the opening into the liquid reservoir chamber.
