  • Replaceable caulking tip for use on caulking cartridges and method of manufacture
    Patent number: 4957225
    Abstract: A replaceable caulking tip is disclosed for use on the tubular nozzle of a caulking cartridge or the like. The tip includes a tubular body which is internally threaded for replaceable engagement on the nozzle. An outlet orifice is formed at the other end of the body with substantial body material surrounding the orifice to permit shaping of the tip, and reshaping if necessary. The orifice is inclined about 12 to 20 degrees, preferably about 15 to 17 degrees, from a plane perpendicular to a longitudinal axis of the tip and is of elongated configuration. The body of the tip is preferably formed from a hard material permitting shaping of the body yet facilitating repeated use of the tip, the body material being rounded or faired about the orifice. An indexing notch is formed on the body to assure proper angular alignment of the tubular body during steps of inclining and elongated the orifice in a method of manufacture.
