Protective cover

Abstract

A protective cover is comprised of a flexible material, such as natural latex, and may be colored or may include a design. A hole may be included for inserting a straw or as a drinking spout, and the hole may be reinforced. The protective cover may be comprised of a central circular portion and a circumferential side portion and may be sized for fitting bar glasses. An edge on the side portion may be formed by folding the edge over itself and adhering the folded layers together, providing a resilient elastic band for retaining the protective cover on a glass.

What is claimed is: 
     
         1 . A protective cover comprises:
 a flexible material having a circular portion, the circular portion having a center portion extending outwardly from a center point of the circular portion, the center portion being substantially planar with respect to a reference plane;   a circular hole disposed off center from the center point of the circular portion within the center portion;   a circumferential side extending in a direction extending substantially transversely from the reference plane along a circumference of the circular portion; and   an edge formed on a distal end of the circumferential side away from the circular portion;   a washer, wherein the washer surrounds the circular hole and reinforces the flexible material around the circular hole; and   a pull tab sealably disposed on the washer and covering the hole, wherein the pull tab is removable by pulling on the pull tab.   
     
     
         2 . The cover of  claim 1 , wherein the flexible material is a natural latex. 
     
     
         3 . The cover of  claim 2 , wherein the natural latex is colored. 
     
     
         4 . The cover of  claim 1 , further comprising a pull tab, wherein the pull tab covers the hole. 
     
     
         5 . The cover of  claim 1 , wherein the hole has a diameter selected in a range less than 0.48 centimeters. 
     
     
         6 . The cover of  claim 5 , wherein the hole diameter is selected in a range of 1.9 millimeters to 2.4 millimeters. 
     
     
         7 . The cover of  claim 6 , wherein the hole diameter is 1.9 millimeters. 
     
     
         8 . The cover of  claim 6 , wherein the circular portion has a diameter selected in a range of 5.1 centimeters to 9.5 centimeters. 
     
     
         9 . The cover of  claim 8 , wherein the circular portion diameter is selected in a range of 6.2 centimeters to 6.5 centimeters. 
     
     
         10 . The cover of  claim 9 , wherein the circular portion diameter is about 7 centimeters. 
     
     
         11 . The cover of  claim 9 , wherein a height of the circumferential side is selected such that the distance from the edge to the circumference of the circular portion is greater than 2.2 centimeters. 
     
     
         12 . The cover of  claim 11 , wherein the circumferential side height is selected in a range of 2.3 centimeters to 3.8 centimeters. 
     
     
         13 . The cover of  claim 12 , wherein the circumferential side height is selected in a range of 2.5 centimeters to 3.2 centimeters. 
     
     
         14 . The cover of  claim 13 , wherein the circumferential side height is 3.2 centimeters. 
     
     
         15 . The cover of  claim 13 , wherein the flexible material has a thickness selected in a range of 0.13 millimeters to 2.5 millimeters. 
     
     
         16 . The cover of  claim 15 , wherein the flexible material thickness is selected in a range of 0.13 millimeters to 0.25 millimeters. 
     
     
         17 . The cover of  claim 16 , wherein the flexible material thickness is 0.25 millimeters. 
     
     
         18 . The cover of  claim 1 , wherein the flexible material has a thickness selected in a range of 0.13 millimeters and 0.25 millimeters and the circular portion has a diameter selected in a range of 5.1 centimeters to 9.5 centimeters. 
     
     
         19 . The cover of  claim 1 , wherein the flexible material has a thickness selected in a range of 0.13 millimeters and 0.25 millimeters, and the edge is formed by folding the distal end of the circumferential side over itself. 
     
     
         20 . The cover of  claim 19 , wherein the distal end is folded over three times. 
     
     
         21 . The cover of  claim 20 , wherein the flexible material is natural latex, and the edge is cured after it is formed, such that a flat rim is formed by binding folded layers of the edge together during curing.
