Drinking cup

Abstract

A drinking cup includes a container and a detachable closure. The closure has a connection end for connection to the container, the connection end being open for receipt of liquid from within the container. The closure has a closed end opposite the connection end and a drinking rim formed at the peripheral edge of the closed end. The closure has a side wall extending between the connection end and the closed end, and at least one opening that facilitates the passage of liquid from within the container to the drinking rim. A seal is supported by the closure and extends around an outside surface of the side wall, sealing the drinking rim against the passage of liquid through the drinking rim. The seal is flexible and responsive to pressure to lift away from the drinking rim to allow passage of liquid through the drinking rim for drinking from the cup.
