ABSTRACT:
A polymeric grease gun comprising a tubular body of polymeric material which defines a chamber for containing grease, a forward end cap having a grease pump, pump lever and a nozzle, a polymeric rear end cap, and a plunger for urging grease forward into the chamber, where the end caps are secured to the tubular body by means of lugs at each end of the tube which engage blind-ended arcuate slots in the leading edge of the end caps so that the caps are retained on the body against an internal axial force which tends to separate the caps from the body. The caps are also secured on the tubular body by means of springing members extending from the ends of the tubular body which engage corresponding portions of the end caps so that the springing members are resiliently held against the interior of the caps.
