Beverage container lid with selectable drinking mode

Abstract

A lid for a beverage container having a first drinking opening, a second drinking opening, and a selector. The selector is configured to linearly slide between a first position in which the first drinking opening is accessible and the second drinking opening is inaccessible, and a second position in which the second drinking opening is accessible and the first drinking opening is inaccessible.

What is claimed is: 
     
         1 . A lid for a beverage container, the lid comprising:
 a lid body, comprising:
 a first side configured to face outside a beverage container, and 
 a second side configured to face inside the beverage container; 
   a first drinking opening extending through the lid body;   a second drinking opening extending through the lid body;   a selector disposed on the first side of the lid body and configured to slide between a first position in which the first drinking opening is accessible and the second drinking opening is inaccessible, and a second position in which the second drinking opening is accessible and the first drinking opening is inaccessible; and   a trapdoor disposed on the second side of the lid body and configured to removably seal the first drinking opening when the selector is in the first position and to unseal the first drinking opening when the selector is in the second position.   
     
     
         2 . The lid of  claim 1 , wherein when the selector is in the first position the trapdoor is biased to seal the first drinking opening and configured to be pushed away from the first drinking opening to unseal the first drinking opening. 
     
     
         3 . The lid of  claim 1 , wherein the trapdoor is prevented from sealing the first drinking opening when the selector is in the second position. 
     
     
         4 . The lid of  claim 1 , wherein the trapdoor comprises a protrusion configured to extend through the first drinking opening and above the first side of the lid body,
 wherein the selector comprises a rib extending downward from selector, and   wherein the protrusion and the rib are configured to engage in the second position to push the trapdoor away from the first drinking opening to unseal the first drinking opening.   
     
     
         5 . The lid of  claim 4 , wherein the selector comprises a selector opening configured to align with the first drinking opening in the first position, and wherein the selector opening comprises a cutout configured to receive at least a portion of the protrusion in the first position. 
     
     
         6 . The lid of  claim 4 , wherein the protrusion is a rim having a raised leading edge that is configured to extend through the first drinking opening and above the first side of the lid body, and
 wherein the raised leading edge and the rib are configured to engage in the second position to push the trapdoor away from the first drinking opening to unseal the first drinking opening.   
     
     
         7 . The lid of  claim 6 , wherein the rib extends lower than the raised leading edge in the first position. 
     
     
         8 . The lid of  claim 4 , wherein the rib comprises a ramp leading toward the cutout. 
     
     
         9 . The lid of  claim 1 , wherein the selector comprises a seal member configured to seal the second opening when the selector is in the first position. 
     
     
         10 . The lid of  claim 9 , wherein the seal member is integral with the selector. 
     
     
         11 . The lid of  claim 1 , wherein the selector is configured to slide to a third position in which the selector is configured to be removed from the lid. 
     
     
         12 . The lid of  claim 11 , wherein the trapdoor comprises a first protrusion and the selector comprises a second protrusion, wherein the first protrusion and the second protrusion are configured to engage with each other to resist sliding of the selector from the second position to a third position. 
     
     
         13 . The lid of  claim 1 , wherein the trapdoor is configured to engage with a straw to unseal the first drinking opening when the selector is in the first position. 
     
     
         14 . The lid of  claim 1 , wherein the first drinking opening is nearer to a center of the lid than is the second drinking opening. 
     
     
         15 . A beverage container, comprising:
 the lid of  claim 1 ; and   a vessel comprising an opening,   wherein the lid is configured to attach to and close the opening of the vessel.   
     
     
         16 . A lid for a beverage container, the lid comprising:
 a lid body;   a drinking opening;   a mount extending downwardly from the lid body; and   a trapdoor coupled to the mount;   wherein the trapdoor is configured to slide within the mount between a first position, in which the trapdoor can rotate within the mount to removably seal the first drinking opening, and a second position, in which the trapdoor cannot rotate within the mount and is retained away from the drinking opening.   
     
     
         17 . The lid of  claim 16 , further comprising a torsional spring,
 wherein the trapdoor is biased by the torsional spring to seal the drinking opening, and   wherein when the trapdoor is in the second position, the torsional force of the torsional spring is resisted by interference with structure of the mount such that the trapdoor cannot rotate sufficiently to seal the drinking opening.   
     
     
         18 . The lid of  claim 16 , wherein when the trapdoor is in the second position, the trapdoor is retained at an angle with respect to the drinking opening. 
     
     
         19 . The lid of  claim 18 , wherein the angle between the trapdoor and the drinking opening is in a range of 60° to 150°. 
     
     
         20 . The lid of  claim 18 , wherein the angle between the trapdoor and the drinking opening is an obtuse angle. 
     
     
         21 . The lid of  claim 16 , wherein the trapdoor comprises a seal member configured to seal around the drinking opening. 
     
     
         22 . The lid of  claim 16 , wherein the trapdoor is configured to engage with a straw to unseal the drinking opening in the first position. 
     
     
         23 . A beverage container, comprising:
 the lid of  claim 16 ; and   a vessel comprising an opening,   wherein the lid is configured to attach to and close the opening of the vessel.
