  • Device for removing dried caulking compound from caulking tube nozzle
    Patent number: 6516972
    Abstract: A tool for removing dried caulking compound from the nozzle of a caulking tube includes a handle and a generally cylindrical member attached to the handle. The generally cylindrical member has a threaded portion, e.g., similar to a wood screw, which is adapted to threadably engage dried caulking compound disposed within the nozzle by rotating the handle. The caulking compound then is removed from the nozzle simply by pulling the tool away from the nozzle. In an alternative embodiment, an elongate member is attached to the handle at one end and a coiled portion at the other end is adapted to threadably engage dried caulking compound disposed within the nozzle.
