Lightweight applicator system for efficient extrusive dispensing of work material

A lightweight applicator system for extrudably dispensing work material from a cartridge comprising:

• a hybrid body having a cartridge frame portion of a first material composition coupled to a base frame portion of a second material composition;
• said base frame portion defining a hub structure and a handle extending therefrom;
• said cartridge frame portion including a proximal closed end and a plurality of transversely spaced frame members separately projecting longitudinally from said proximal closed end to a distal end to define a cartridge loading compartment therebetween, said proximal closed end having a one-piece configuration formed by a bracing member integrally formed to extend between said frame members, at least a portion of said transversely spaced frame members and said bracing member being captured in conformed manner within a substantially U-shaped embedding groove of said hub structure;
• and,
• a drive portion coupled to said hybrid body, said drive portion including a drive member selectively displaceable responsive to user actuation for extruding work material from a cartridge retained within said cartridge frame portion.

• a body of hybrid compositional structure having a cartridge frame portion of a first material composition coupled to a base frame portion of a second material composition;
• said cartridge frame portion including a proximal closed end, a distal end, and a pair of transversely spaced frame members separately projecting longitudinally therebetween to define a skeletal cage structure looped about a cartridge loading compartment, said proximal closed end having a one-piece configuration formed by a bracing member integrally formed to extend between said frame members, at least a portion of said transversely spaced frame members and said bracing member being captured within a substantially U-shaped embedding groove of said base frame portion in at least partially embedded manner;
• said base frame portion defining a hub structure and a handle extending therefrom, said hub structure including a plurality of stabilizing clip members extending into said cartridge loading compartment;
• and,
• a drive portion coupled to said body, said drive portion including a drive member selectively displaceable responsive to user actuation for engaging a cartridge retained by said cartridge frame portion to extrude work material therefrom.
