A process for manufacturing a xerographic toner cartridge containing a heat-fusible toner powder situated in a container having an open end surrounded by a peripheral lip. An elongated tongue of a material having non-directional shear strength characteristics is placed on top of the opening, with a thermoplastic adhesive layer being disposed between the container lip and the tongue. The adhesive is activatable by heat and pressure, and once activated adheres more strongly to the peripheral container lip than to the tongue. The adhesive is bonded to the tongue and the peripheral lip by a heated platen having a shape conforming to that of the lip. The heat and pressure applied is sufficient to form the desired adhesive bonds, but the temperature and time employed are insufficient to cause deterioration of the toner powder in the container. The tongue is more than twice as long as the peripheral lip, and the free end of the tongue is folded back against the bonded portion thereof to act as a tab, the free end of said tab being detachably secured to an adjacent wall of the container.
