Abstract
Abstract A semiannular paint can attachment combines brush scraping means with a shallow cavity for catching and retaining the paint drippings up to a certain level, above which the excess returns to the can through an internal opening. A pouring lip partially surrounds the opening, functioning in a dual capacity as a scraper for the brush, and to prevent paint poured from the can from dripping over the sides of the can.

A semicircular attachment for the open mouth of a paint can which comprises in combination: a peripheral flange constructed and arranged to fit over and engage the edge of the can, the internal straight edge of said attachment connected between inner edges of said flange and forming a narrow scraping ledge, a paint well laterally enclosed between said peripheral flange and said narrow scraping ledge, and substantially depressed below the horizontal plane of said ledge, said well having an opening in the lateral wall on the side opposite said ledge at a level substantially above the bottom of said well, and a curved lip disposed between the upper edge of said opening and the inner edge of said flange.
Claim 2
Dependent Claim
119 words
A semicircular attachment for the open mouth of a paint can which comprises in combination: a peripheral flange constructed and arranged to fit over and engage the edge of the can, the internal straight edge of said attachment connected between inner edges of said flange and forming a narrow scraping ledge, a paint well laterally enclosed between said peripheral flange and said narrow scraping ledge, and substantially depressed below the horizontal plane of said ledge, said well having an opening in the lateral wall on the side opposite said ledge at a level substantially above the bottom of said well, and a curved lip disposed between the upper edge of said opening and the inner edge of said flange.

Claim 5
Dependent Claim
46 words
The combination in accordance with claim 3 wherein the wall declining from said ledge forms an internal angle with the principal horizontal plane of said ledge which is at least about twice the internal angle formed by the other said wall and a parallel horizontal plane.
Claim 6
Dependent Claim
