Abstract
Abstract Calking cartridge nozzles suitable for resealing a calking cartridge comprising an elongated, hollow nozzle body which terminates upwardly in a solid, narrow neck. A severable tip of hollow construction and of configuration to overfit and seal the nozzle body extends upwardly from the neck. By severing the nozzle body below the neck, the tip and attached neck can be employed for nozzle sealing purposes by rotating the tip through one hundred and eighty degrees and then pressing it downwardly upon the nozzle body. In a first modification, the nozzle body is provided with an outwardly projecting ring and the tip is provided with an inwardly projecting ring which cooperate in sealing engagement. In a second embodiment, the nozzle body is provided with an outwardly projecting ring and the tip is provided with a plurality of inwardly projecting pins which secure to the ring. In a third embodiment, the nozzle body is provided with an inwardly projecting peripheral groove and the tip is formed with an inwardly projecting ring which seats within the groove for sealing purposes. In a fourth embodiment, the nozzle body is provided with an inwardly projecting peripheral groove and the tip is formed with a plurality of inwardly projecting pins.
