Abstract
An insulated beverage container (100) has a tumbler (110), a handle assembly (120) including a collar (122) attached to the top of the tumbler, and a valved lid assembly (200). The tumbler has multiple wall construction, wherein the inner two walls (114, 116) define an insulating volume (118) therebetween that may be partially evacuated. The valved lid assembly includes an upwardly biased valve (240), near the top of the lid assembly, that may be moved from a closed position wherein the valve abuts a valve seat (214) in the lid assembly, and an open position wherein the valve is spaced apart from the valve seat. A non-skid base (102) with integral, upwardly extending grip elements provides a grip to facilitate handling of the tumbler.
