Abstract

Abstract A device for cleaning the top surface of beverage cans is formed from a circular disk provided with symmetrical openings and has a plurality of bristles extending downwardly from a bottom surface thereof. A cylindrical sidewall surrounds the bristles and a bottom circular edge of the cylindrical sidewall extends downwardly past the ends of the bristles. First and second radially spaced circular brush portions are formed of a diameter to engage the gutters formed on two different standard beverage cans. Radially extending brush portions are positioned to clean the flat top surface of beverage containers. In use, the circular plate is placed on top of a beverage can, with the bristles extending downwardly and engaging the top surface of the beverage can. Water is then allowed to run through the openings, while the circular plate is rotated back and forth with the bristles in engagement with the beverage can. This results in a thorough cleaning of the top surface of the beverage can.

Claims Analysis

Total Claims: 2
Claim 1
Independent Claim 219 words
A new and improved can cleaning device, comprising: a circular plate having a diameter slightly larger than a can to be cleaned; a downwardly extending cylindrical sidewall formed on said circular plate; four radially extending openings symmetrically formed through said circular plate; each of said openings tapering in width from a narrow radially inner end adjacent a central portion of said circular plate to a wider radially outer end adjacent an outer edge portion of said circular plate; each of said openings having opposed radiused inner and outer end walls; a plurality of bristles extending downwardly from a bottom surface of said circular plate; said cylindrical sidewall surrounding said bristles and a circular bottom edge of said cylindrical sidewall extending downwardly beyond the extent of said bristles; said bristles forming a first generally circular radially outer brush portion composed of circumferentially spaced discrete arcuate segments dimensioned for engagement in a gutter formed on a top surface of a first standard size beverage can and a second, radially spaced, generally circular radially inner brush portion composed of circumferentially spaced discrete arcuate segments dimensioned for engagement in a gutter formed on a top surface of a second standard size beverage can; and said bristles also forming four radially extending circumferentially spaced brush portions symmetrically disposed between said four radially extending openings.
Claim 2
Dependent Claim 219 words
A new and improved can cleaning device, comprising: a circular plate having a diameter slightly larger than a can to be cleaned; a downwardly extending cylindrical sidewall formed on said circular plate; four radially extending openings symmetrically formed through said circular plate; each of said openings tapering in width from a narrow radially inner end adjacent a central portion of said circular plate to a wider radially outer end adjacent an outer edge portion of said circular plate; each of said openings having opposed radiused inner and outer end walls; a plurality of bristles extending downwardly from a bottom surface of said circular plate; said cylindrical sidewall surrounding said bristles and a circular bottom edge of said cylindrical sidewall extending downwardly beyond the extent of said bristles; said bristles forming a first generally circular radially outer brush portion composed of circumferentially spaced discrete arcuate segments dimensioned for engagement in a gutter formed on a top surface of a first standard size beverage can and a second, radially spaced, generally circular radially inner brush portion composed of circumferentially spaced discrete arcuate segments dimensioned for engagement in a gutter formed on a top surface of a second standard size beverage can; and said bristles also forming four radially extending circumferentially spaced brush portions symmetrically disposed between said four radially extending openings.
