Travel beverage container

Abstract

A beverage container has a thermally insulated base defining a reservoir and a cover assembly removably mountable on the base for closing the reservoir. The cover assembly includes a cap defining a recess open to ambient and defines a baffled passage between the recess and the reservoir closeable by a valve assembly including a toggle mechanism actuatable by a push button disposed centrally of the cap and spaced from the recess, for alternately latching the valve in closed and open conditions relative to the passage. The valve assembly includes a gasketed movable valve member engageable with a rigid sharp edge on a valve seat in the closed condition so that the gasket yieldably deforms around the sharp edge to provide a fluid-tight seal.

       11 . A beverage container comprising: 
 a base defining a beverage-containing reservoir,    a cover assembly removably mountable on the base for closing the reservoir,    the cover assembly defining a passage for providing communication between the reservoir and ambient, and    a valve assembly carried by the cover assembly and having a valve seat and a valve member movable between a closed condition closing the passage and an open condition opening the passage,    one of the valve seat and the valve member including a relatively soft flexible and resilient gasket,    another of the valve seat and the valve member including a rigid sharp edge which engages the gasket in the closed condition of the valve member so that the gasket yieldably deforms around the sharp edge for providing a fluid-tight seal.    
   
   
       12 . The container of  claim 11 , wherein the gasket is included on the valve member and the sharp edge is disposed on the valve seat.  
   
   
       13 . The container of  claim 12 , wherein the container has a central axis, the valve member moving axially of the container between its open and closed conditions.  
   
   
       14 . The container of  claim 13 , wherein the valve member moves toward the reservoir in moving from its closed condition to its open condition.  
   
   
       15 . The container of  claim 11 , wherein the cover assembly is threadedly engageable with the base.  
   
   
       16 . The container of  claim 15 , and further comprising a cover gasket disposed between the cover assembly and the base and engageable with both to provide a fluid-tight seal therebetween.  
   
   
       17 . The container of  claim 11 , wherein the base includes a reservoir portion and an annular neck portion which is snap-fitted onto the reservoir portion.
