ABSTRACT:
The disclosure relates to an enclosed cup like drinking receptacle having a cover provided with a drinking opening therein which is disposed near the peripheral portion of the cover; the drinking opening being controlled by a liquid dispensing valve and a pneumatic pressure relief valve, both carried by a common manual actuator such that both valves are moved in unison and the dispensing valve being moveable relative to its seat a short distance without breaking its seal relative to said seat and to provide for sufficient movement of the pressure relief or vent valve to vent pneumatic pressure from the interior of said receptacle and cover so as to prevent unwarrented flow of hot beverages or the like through said dispensing valve and said drinking opening and thereby allowing a person to drink through said drinking opening with the normal flow of a hot beverage or other beverage therethrough.
