Apparatus and method for drinking container cover

Abstract

A cover configured to cover an opening of a drinking container from unwanted contamination. The cover can have a first portion that can move from a first position in which the first portion is generally parallel with a surface of the cover to a second position in which the first portion extends away from the surface of the cover. The cover can also have a second portion that can move from a first position in which the second portion is generally parallel with the surface of the cover to a second position in which the second portion extends away from the surface of the cover. When the first and/or second flaps are in the second position, the first and/or second flaps can surround at least a portion of an outside surface of a drinking container adjacent to the opening and cover the opening of the drinking container.

What is claimed is: 
     
         1 . A cover configured to selectively cover a drinking container, comprising:
 a first cover surface and a second cover surface, the second cover surface opposing the first cover surface; and   a first preformed crease formed in the cover;   wherein:
 the cover is configured such that a first cover portion is movable from a first position in which the first cover portion is generally parallel to the second cover surface to a second position in which the first cover portion extends at an angle away from the second cover surface; 
 the cover is configured to bias the first cover portion to bend about at least the first preformed crease when the first cover portion is moved from the first position to the second position; and 
 when the first cover portion is moved to the second position, the first cover portion is configured to extend around at least a portion of an outside surface of a drinking container below an opening of the drinking container. 
   
     
     
         2 . The cover of  claim 1 , wherein the cover has an outer perimeter that is configured to be at least as big as an outer perimeter of a rim of a drinking container. 
     
     
         3 . The cover of  claim 1 , wherein the cover comprises a second preformed crease formed in the cover, and wherein the cover is configured to bias the first cover portion to bend about the first and second preformed creases when the first cover portion is moved from the first position to the second position. 
     
     
         4 . The cover of  claim 1 , wherein the cover comprises a second cover portion that is movable from a first position in which the second cover portion is generally parallel to the second cover surface to a second position in which the second cover portion extends at an angle away from the second cover surface. 
     
     
         5 . The cover of  claim 4 , wherein the cover comprises a second preformed crease formed in the cover, wherein the cover is configured to bias the second cover portion to bend about the second preformed crease when the second cover portion is moved from the first position to the second position. 
     
     
         6 . The cover of  claim 4 , wherein the cover comprises a second preformed crease and a third preformed crease formed in the cover, wherein the cover is configured to bias the second cover portion to bend about the second preformed crease and the third preformed crease when the second cover portion is moved from the first position to the second position. 
     
     
         7 . The cover of  claim 1 , wherein the entire cover is made from one or more substantially non-stretchable materials. 
     
     
         8 . The cover of  claim 1 , wherein, when the first cover portion is in the second position, the cover is configured to be positionable over an opening of a drinking container such that the second cover surface is configured to be positionable over an entire opening of the drinking container and the first cover portion is configured to at least partially surround an outside surface of the drinking container adjacent to a rim of a drinking container. 
     
     
         9 . A cover configured to selectively cover a drinking container, comprising:
 a first cover surface and a second cover surface, the second cover surface opposing the first cover surface; and   a first side and a second side, the second side being opposite to the first side;   wherein:
 the cover is configured such that a first cover portion is movable from a first position in which the first cover portion is generally parallel to the second cover surface to a second position in which the first cover portion extends at an angle away from the second cover surface; 
 the cover is biased to move the first cover portion from the first position toward the second position when the first side of the cover is moved toward the second side of the cover; and 
 when the first cover portion is moved to the second position, the first cover portion is configured to extend around at least a portion of an outside surface of a drinking container below an opening of the drinking container. 
   
     
     
         10 . The cover of  claim 9 , comprising a first preformed crease formed in the cover, wherein the cover is configured to bias the first cover portion to bend about at least the first preformed crease when the first cover portion is moved from the first position to the second position. 
     
     
         11 . The cover of  claim 10 , wherein the cover comprises a second preformed crease formed in the cover, and wherein the cover is configured to bias the first cover portion to bend about the first and second preformed creases when the first cover portion is moved from the first position to the second position. 
     
     
         12 . The cover of  claim 9 , wherein the cover has an outer perimeter that is configured to be at least as big as an outer perimeter of a rim of a drinking container. 
     
     
         13 . The cover of  claim 9 , wherein the cover comprises a second cover portion that is movable from a first position in which the second cover portion is generally parallel to the second cover surface to a second position in which the second cover portion extends at an angle away from the second cover surface. 
     
     
         14 . The cover of  claim 13 , wherein the cover comprises a second preformed crease formed in the cover, wherein the cover is configured to bias the second cover portion to bend about the second preformed crease when the second cover portion is moved from the first position to the second position. 
     
     
         15 . The cover of  claim 13 , wherein the cover comprises a second preformed crease and a third preformed crease formed in the cover, wherein the cover is configured to bias the second cover portion to bend about the second preformed crease and the third preformed crease when the second cover portion is moved from the first position to the second position. 
     
     
         16 . The cover of  claim 9 , wherein the entire cover is made from one or more substantially non-stretchable materials. 
     
     
         17 . The cover of  claim 1 , wherein, when the first cover portion is in the second position, the cover is configured to be positionable over an opening of a drinking container such that the second cover surface is configured to be positionable over an entire opening of the drinking container and the first cover portion is configured to at least partially surround an outside surface of the drinking container adjacent to a rim of a drinking container.
