Can base with vertical seal on side of can

Abstract

A coaster type device of cup design that will seal on the vertical side of a can and or container, here forth “can”, made of a potentially corrosion prone material that may cause unwanted marks on a surface the can could be placed. The device would be manually applied to the can and would stay on the can due to mechanical interface and frictional fit between the seal area and the vertical side of the can. The seal on the can and the solid physical coaster would produced a contained volume of the can base from the sealed surface down blocking any unwanted transfer from the can to the surface it would be placed.

1 . A can base to prevent and block the transfer of corrosion from a can to a surface it would be placed on by the means of containing the volume of the bottom of the can constituted by a seal on the vertical side of the can in conjunction with the physical attributes supplied by the vertical and horizontal wall components of the invention. 
     
     
         2 . The can base of  claim 1  would seal on the side of the can reducing the moisture and other environmental elements, caustic to the can, to reach the base of the can below the seal potentially reducing corrosion to the can. 
     
     
         3 . The can base of  claim 1  would seal on the side of the can producing said volume and contain any corrosion and or elements in the volume and keeping the unwanted material off of the surface the can would be placed. 
     
     
         4 . The can base of  claim 1  being made of materials that are non abrasive to the surface it would be placed, would reduce the scratching and damage to said surface.
