ABSTRACT:
A drinking receptacle (10) comprised of a beverage container (12) having a removeable cover (16) and an insulating sheath (14) mounted on the sidewall (20) of the container, is described. The cover serves as a closure for the open end of the container and is comprised of a canted top wall (58) having a vent opening (62) and a drinking slot (64). The drinking slot enables virtually the entire beverage contents of the container to be drank. The sheath is preferably made of an extruded sheet of closed cell polyolefin elastomeric material having an outer laminated coating. This enables a person to comfortably hold the drinking receptacle in their hand even when the temperature of the beverage held in the container is at or near the boiling point.
