Abstract
A bendable caulking nozzle extension device for use with a caulking tube having a nozzle, said device comprising an elongated tube portion extending between a proximal base portion and a distal tip portion, and having a hollow passageway defined therein. The elongated tube portion is constructed from a flexible, resilient material that may be repeatedly and forcibly deformed. An attachment means is positioned within the proximal base portion for releasably affixing said device to the nozzle of the caulking tube. A deformable stiffening element is positioned on the elongated tube portion, and is constructed of a material that allows it to be repeatedly and forcibly deformed whilst substantially retaining such deformed configuration after the removal of a deforming force. Caulking material flowing from the caulking tube flows into said hollow passageway, and out of the exit aperture of the distal tip portion to a work surface remote from the nozzle of the caulking tube.
