Beverage container lid assembly

Abstract

A lid assembly including a lower lid, a plug element movable relative to the lower lid between a plugged position and an unplugged position, and an upper lid rotatably movable relative to the lower lid between an open position in which the plug element is in the unplugged position and a closed position in which the plug element is in the plugged position. The lid assembly further includes a rotational interface adapted to couple the upper lid to the lower lid, the rotational interface including a resilient cleat, a ledge, and a backstop. One of the lower lid and upper lid includes the resilient cleat and an other of the lower lid and upper lid includes the ledge. The resilient cleat engages the ledge to secure the upper lid in rotational engagement with the lower lid. The backstop is positioned to inhibit disengagement of the resilient cleat from the ledge.

         2 . A lid assembly as claimed in  claim 1 , wherein the upper lid assembly is configured such that rotational movement of the upper lid relative to the lower lid causes the plug element to move relative to the lower lid. 
     
     
         3 . A lid assembly as claimed in  claim 1 , wherein the other of the lower lid and the upper lid includes the backstop and defines a space between the backstop and the ledge, the space adapted to receive the resilient cleat. 
     
     
         4 . A lid assembly as claimed in  claim 1 , wherein the lid assembly is generally cylindrical and defines a central axis, and wherein the backstop includes an engagement surface positioned at an angle greater than zero degrees relative to the central axis. 
     
     
         5 . A lid assembly as claimed in  claim 1 , wherein the upper lid includes the resilient cleat and the lower lid includes the ledge. 
     
     
         6 . A lid assembly as claimed in  claim 1 , wherein the lid assembly is generally cylindrical and defines a central axis, and wherein the resilient cleat faces away from the central axis and the ledge faces toward the central axis. 
     
     
         7 . A lid assembly as claimed in  claim 1 , wherein the rotational interface further includes a closed rotational stop positioned to inhibit rotational movement of the upper lid relative to the lower lid in a first rotational direction when the upper lid is in the closed position, and wherein the resilient cleat includes a closed overhang that axially overlaps the closed rotational stop to inhibit axial movement of the upper lid relative to the lower lid in an axial direction. 
     
     
         8 . A lid assembly as claimed in  claim 7 , wherein the rotational stop is formed integrally with and at least partially supports the backstop. 
     
     
         9 . A lid assembly as claimed in  claim 7 , wherein the rotational stop and the backstop are cooperatively arranged in an L-shape. 
     
     
         10 . A lid assembly as claimed in  claim 7 , wherein the rotational interface further includes an open rotational stop positioned to inhibit rotational movement of the upper lid relative to the lower lid in a second rotational direction when the upper lid is in the open position, and wherein the resilient cleat further includes an open overhang that axially overlaps the open rotational stop to inhibit axial movement of the upper lid relative to the lower lid in the axial direction. 
     
     
         11 . A beverage container assembly comprising:
 a container; and   a lid assembly coupled to the container, the lid assembly comprising:
 a lower lid; 
 a plug element movable relative to the lower lid between a plugged position and an unplugged position; 
 an upper lid rotatably movable relative to the lower lid between an open position in which the plug element is in the unplugged position and a closed position in which the plug element is in the plugged position; and 
 a rotational interface adapted to couple the upper lid to the lower lid, the rotational interface including:
 a resilient cleat, wherein one of the lower lid and upper lid includes the resilient cleat; 
 a ledge, wherein an other of the lower lid and the upper lid includes the ledge, and the resilient cleat engages the ledge to secure the upper lid in rotational engagement with the lower lid; and 
 a backstop positioned to inhibit disengagement of the resilient cleat from the ledge. 
 
   
     
     
         12 . A lid assembly as claimed in  claim 11 , wherein the upper lid assembly is configured such that rotational movement of the upper lid relative to the lower lid causes the plug element to move relative to the lower lid. 
     
     
         13 . A beverage container assembly as claimed in  claim 11 , wherein the other of the lower lid and the upper lid includes the backstop and defines a space between the backstop and the ledge, the space adapted to receive the resilient cleat. 
     
     
         14 . A beverage container assembly as claimed in  claim 11 , wherein the lid assembly is generally cylindrical and defines a central axis, and wherein the backstop includes an engagement surface positioned at an angle greater than zero degrees relative to the central axis. 
     
     
         15 . A beverage container assembly as claimed in  claim 11 , wherein the upper lid includes the resilient cleat and the lower lid includes the ledge. 
     
     
         16 . A beverage container assembly as claimed in  claim 11 , wherein the lid assembly is generally cylindrical and defines a central axis, and wherein the resilient cleat faces away from the central axis and the ledge faces toward the central axis.
