Method of protecting the open top of a beer can and a soda can against contamination by insects, dirt and debris

Abstract

A cover for the open top of a soda can or beer can is substantially round and has a pair of parallel sides together with an annular bevel or chamfer to accommodate either a soda can or a beer can. The beer can has a larger diameter at its annular rim than that of the soda can, so that (in use) the cover is reversed. The cover may contain a trademark, logo, company name or message for promotional purposes. An alternate cover is substantially half-round, and a further embodiment is substantially arcuate.

       8 . The method of protecting an opened “pop top” can of soda or beer against dirt, insects, debris, wherein both cans have a top portion provided with a circumferential annular lip, the annular lip of one can having an internal diameter which is larger than an annular lip of the other can, comprising the steps of providing a cover comprising a substantially-flat annular disc having a chamfered circumferential edge, thereby defining a pair of substantially-flat sides of the disc, such that one side of the disc has a diameter which is larger than the diameter of the other side of the disc, opening one can, placing the disc on the top of one can with the one larger side of the disc facing down, alternately opening the other can, and placing the disc on the top of the other can with the other smaller side of the disc facing down.  
   
   
       9 . A method of covering an open top of a lift tab can of a beverage to prevent flies, insects, cigarette ashes, dirt or debris from entering into the can, the top of a beer can having an annular lip defining a larger diameter and the top of a soda can having an annular lip defining a smaller diameter, the method comprising the steps of: 
 providing a circular disc having a top and a parallel bottom, the top of the disc having a larger diameter than the bottom of the disc, the diameter of the top of the disc being receivable within the annular lip of the beer can and the diameter of the bottom of the disc being receivable within the annular lip of the top of the soda can,    placing the circular disc on the open top of the beer can with the top of the disc in contact with the top of the beer can, and    placing the circular disc on the open top of the soda can with the bottom of the disc in contact with the top of the soda can wherein the circular disc may be used on the beer can or the soda can.    
   
   
       10 . The method of  claim 9 , wherein the top of the disc is spaced apart from the bottom of the disc by an annular chamfered circumference.  
   
   
       11 . The method of  claim 9 , wherein the top or the bottom of the disc has a logo, slogan, or trademark on it.  
   
   
       12 . The method of covering an open top of a lift tab soda can or a beer can, wherein the beer can has a top portion formed by an annular lip which has a larger diameter than a corresponding diameter of an annular lip of the top portion of the soda can, comprising the steps of: 
 providing a removable universal cover independent of the can for use when one of the cans is popped open, said cover comprising a substantially half-round disc having a top and a parallel bottom, a planar edge and an arcuate edge between the top and the bottom, the arcuate edge being chamfered, such that the top of the disc has a larger diameter than the bottom of the disc,    covering the open top of the soda can by placing the bottom of the disc on the open top of the soda can,    covering the open top of the beer can by reversing the disc and placing the top of the disc on the open top of the beer can,    thereby preventing flies, insects, cigarette ashes, dirt or debris from entering into the open top, and thereby improving the hygienic and safety conditions.
