Coaster with sidewalls that seal the can's circumference

Abstract

A coaster type device having a base with or without an integrated boss, the base is attached to side walls that end in a seal around the can's circumference. The combination of the coaster being made of one piece without openings and the seal around the circumference of the can allows it to trap the rust in the coaster even when under direct water. This allows the device to be used in a daily routine where a product is normally placed for use such as a shaving cream can in the shower under direct water or a bug spray left outside on a table in the rain.

1 . A coaster type device for holding a metal can comprising:
 a base with connected side walls that end with an outward extension that comes in contact with a can whereby said outward extension seals the circumference of said can   
     
     
         2 . The coaster of  claim 1 , wherein said coaster is made of a flexible plastic. 
     
     
         3 . The coaster of  claim 1  wherein said coaster is made of one piece without breaches. 
     
     
         4 . The coaster of  claim 1  wherein said outward extension creates an offset between said sidewall and said can. 
     
     
         5 . A coaster type device for holding a metal can comprising:
 a base with a centrally located protrusion of a closed shape with a hollow inside (boss), said base has surrounding side walls that end in a rim which extends inward, coming in contact with said can to create a seal around said can's circumference.   
     
     
         6 . The coaster of  claim 5 , wherein said coaster is made of a flexible plastic. 
     
     
         7 . The coaster of  claim 5 , wherein said coaster is made of one piece without breaches. 
     
     
         8 . The coaster of  claim 5 , wherein said outward extension creates an offset between said sidewall and said can.
