Coasters for cans

Abstract

A coaster for being attached to the bottom of a can of paint, solvent or the like comprises a base having one or more drain holes therein, a peripheral wall, tabs formed at the upper edge of the peripheral wall fitting over a bead at the bottom of the can, and ridges formed in the upper surface of the base. The effect is to provide air circulation and drainage around the can, eliminating or limiting corrosion.

What is claimed is: 
     
         1 . A coaster for being affixed to a can of standard dimensions, the can being formed so as to include a bead at a lower periphery, the coaster comprising:
 a base coextensive with the lower periphery of the can, and having at least one drainage hole therein;   a peripheral wall extending upwardly from the base;   a plurality of tabs extending inwardly from the wall, spaced around the wall, and shaped to fit over said bead, retaining said coaster on said can;   a plurality of ribs extending upwardly from the base;   whereby when said coaster is assembled to a can, said coaster is spaced from the can except at said tabs and ribs, providing air circulation and drainage.   
     
     
         2 . The coaster of  claim 1 , further comprising surface features upstanding from the underside of the base, spacing the base from a support surface. 
     
     
         3 . The coaster of  claim 1 , wherein the coaster is formed as a unitary member of a resilient material, and wherein the tabs are shaped and sized so as to be deformed when the coaster is assembled to a can, whereby spring tension exerted due to said deformation retains the coaster securely on the can. 
     
     
         4 . The coaster of  claim 1 , wherein cutouts are provided in the peripheral wall and base under each tab. 
     
     
         5 . The coaster of  claim 1 , where the material of the coaster is selected from the group consisting of high density polyethylene (HDPE), polypropylene, nylon and polycarbonate.
