Cover

Abstract

A cover includes an aperture for a straw, so that the cover can be used with a liquid beverage. The cover is elastically stretchable, and has a central body portion and an outer periphery. The cover can be stretched over an opening of a container so that the central portion covers the opening of the container while the periphery grips the outer side walls of the container. The aperture preferably is in a closed or nearly closed condition, such that insertion of a straw therethrough opens the aperture which then elastically retains the straw in an inserted position and provides a seal. This permits a user to consume the beverage, while still having the beverage protected against contamination or adulteration by drugs, dirt, dust, biologic matter, and the like. The cover is convenient, inexpensive yet effective, and readily portable.

1 . A cover for covering an opening, comprising:
 a central body portion composed of stretchable material;   a thickened periphery surrounding said central body portion, said thickened periphery being composed of stretchable material; and   an aperture through said central body portion.   
     
     
         2 . A cover according to  claim 1 , wherein said aperture is adapted to receive a drinking straw therethrough. 
     
     
         3 . A cover according to  claim 1 , in which the central body portion is a thin flexible body composed of a nonwoven stretchable plastic material. 
     
     
         4 . A cover according to  claim 1 , in which the central body portion is a thin flexible body composed of a nonwoven stretchable material containing rubber. 
     
     
         5 . A cover according to  claim 1 , in which the central body portion is a thin flexible body composed of a woven stretchable plastic material. 
     
     
         6 . A cover according to  claim 2 , in which said aperture is round and is bounded by a thickened periphery for strength against tearing. 
     
     
         7 . A cover according to  claim 2 , in which said aperture is slit-shaped, and is bounded by a thickened periphery for strength against tearing. 
     
     
         8 . A cover according to  claim 1 , in which said aperture is round as is bounded by a thickened periphery for strength against tearing, and is adapted to receive a drinking straw; whereby the cover can be used in public places to protect the contents of a container having liquid beverage against potential adulteration or contamination. 
     
     
         9 . A cover according to  claim 1 , wherein said central body portion and said thickened periphery are composed of TPE material.
