Paint can dispensing ring attachment
First Claim
1. A dispensing ring attachment for a container having a circular opening defined by a sealing rim communicating with the peripheral wall of the container, said attachment being of unitary construction and comprising a circumferentially extending pouring lip issuing from said opening outwardly over said rim and the peripheral wall of the container, said lip terminating with a downwardly turned peripheral edge and communicating inwardly with a downwardly and inwardly tapering thin conical skirt of constant thickness adapted to compressively engage with and provide a continuous liquid tight seal against the sealing rim of the container, said thin conical skirt being circumferentially compressed by engagement with the said rim to form a temporary depressed seat locally changing the contour of both sides of the skirt, said inwardly tapering skirt being disposed at a tapering angle to the plane of said sealing rim in the range of 2 to 10 degrees, and maintaining substantially the same taper both above and below said rim after insertion therewithin, said skirt terminating at its lowermost extremity with an annular collar defined by concentric inner and outer surfaces both smaller in diameter than the sealing rim of the can.

Abstract
The conventional paint can is provided with a dispensing ring which protects the sealing groove and sides of the can from contamination with paint. The dispensing ring comprises a conical lip adapted to extend radially over the can sidewall and terminates inwardly with a downwardly extending conical skirt for compressive engagement by the innermost edge of the can opening.
