ABSTRACT:
A caulk cartridge of recyclable material including an end panel with an integral nozzle. Interior projections integral with the end panel define a cylindrical extension about the open base end of the nozzle and, upon being subjected to the force of the piston-driven plunger thereagainst, inwardly deform and fracture the end panel, breaking away the nozzle, and residue therein, from the end panel.
