Abstract
The present invention is a collapsible cover used to protect an open beverage container from tampering. It is compact and easy to carry and use, is attractive and may be decorated with sports team logos or University symbols or other works of art. It has deep enough extended side walls to prevent someone from unobtrusively removing it to contaminate the beverage and is not too cumbersome to carry in a purse or pocket. The collapsible cover is available in different diameters to allow covering beer or soda cans, bottles, mixed drink glasses or wine glasses. It also has an opening for inserting a straw so that the cover does not have to be removed to consume the beverage.
Claims8
A collapsible safety beverage cover comprising:
- a plurality of truncated conical segments each with radially diminishing diameters from the outermost segment to the innermost segment, each with a common slope, a top surface, an axial height, a top inside diameter, a bottom outside diameter wherein said plurality of truncated conical segments slip fit concentrically within each other with a minor diameter at the axial top of said segment and a major diameter at the axial bottom of said segment and said top inside diameter of said segment is smaller than said bottom outside diameter of the radially internal segment;
- a case with a top and bottom surface in a circular platform with a depending peripheral side wall approximately the same axial height as said segments that has an inside diameter larger than said bottom outside diameter of the outermost segment;
- wherein
- said depending peripheral side wall has a recessed cavity running around external perimeter of said side wall at its approximate axial mid-point;
- wherein
- said plurality of segments are placed within each other and said top surface of said innermost segment is concentrically attached to said bottom surface of said case such that when said outermost segment is pulled axially away from said case it draws the internal segments with it, such that when placed over a beverage container the segments extend below the top of said beverage container making it more difficult to unobtrusively remove said collapsible safety beverage cover;
- wherein
- the interference between the smaller top inside diameter of said segment and the larger bottom outside diameter of the internally adjacent segment limits said segments movement and prevents them from separating completely;
- a cap with a circular platform, an upstanding peripheral wall with an inside diameter a slip fit larger than said outside diameter of said case to be placed over collapsed segments mounted on said case for cleanliness during transport or storage;
- wherein
- said upstanding peripheral side wall has a bump extending radially inward adjacent to the top of said upstanding side wall such that when segments are collapsed into said case and said cap is installed over said case said radially extended bump drops into said cavity on said case retaining assembly for transport or storage;
- and where said to surface of said case has an opening for a drinking straw.
