  • Applicator for dispensing material from a dual chamber cartridge
    Patent number: 5743436
    Abstract: A dispensing applicator includes a body with a handle, a pivotable lever and a front holder with a receptacle that is adapted to removably receive a dual chamber cartridge. In certain embodiments, the majority of the cartridge contents are expelled during a single stroke of the lever, an advantage when used for single patient use in dental or medical fields. In other embodiments, the holder is rotatably connected to the body so that the holder and the cartridge can be moved as needed in an arc in order to vary the orientation of the cartridge relative to the applicator handle. The rotatable connection enables the cartridge to be moved to any one of a number of different orientations as may be desired to provide optimum maneuverability of the applicator in use and to enhance the operator's vision of the application site.
