Patent ID: 6880586

Claim:
An annular fuel filler assembly collar, said annular collar formed from two interlocking structures comprising: a) a first semicircular shaped structure having an outer surface and an inner surface, including; a first pair of terminal ends residing in a common vertical plane, each of said terminal ends including at least one locking means; a top edge forming an upper semicircular rim having a surface perpendicular to the longitudinal axis of said first semicircular shaped structure; a semicircular chamber duct in said top edge, intermediate said pair of terminal ends, said semicircular chamber duct extending from said outer surface to said inner surface; a bottom edge forming a lower semicircular rim having a surface perpendicular to the longitudinal axis of said second semicircular shaped structure, said top edge and said bottom edge residing in spaced apart horizontal planes with respect to each other; a first outer circumferential side separating said top edge and said bottom edge; one or more notches in the upper surface of said first circumferential side intermediate said pair of terminal ends; and an elbow-shaped tubular member integrally formed on said first semicircular member intermediate said first pair of terminal ends, said elbow-shaped tubular member extending outwardly and downwardly from said bottom edge of said first semicircular shaped structure and intermediate said pair of terminal ends, said elbow-shaped tubular member communicating with the inner surface of said first semicircular shaped tubular structure, and b) a second semicircular shaped structure including; a second pair of terminal ends residing in a common vertical plane, each of said terminal ends including at least one locking means, a top edge forming an upper semicircular rim having a surface perpendicular to the longitudinal axis of said second semicircular shaped structure; a bottom edge forming a lower semicircular rim having a surface perpendicular to the longitudinal axis of said second semicircular shaped structure, said top edge and said bottom edge residing in spaced apart horizontal planes with respect to each other; a second outer circumferential side separating said top edge and said bottom edge; one or more notches in the upper surface of said outer circumferential side intermediate said pair of terminal ends; and one or more spaced apart openings in the lower surface of said second semicircular shaped structure, wherein said first semicircular shaped structure and said second semicircular structure are locked together at said first and said second pair of terminal ends in a simple one-motion step by pushing said structures together until locking of said structures is accomplished, said locking being accomplished in the absence of a separate annular locking structure.
