ABSTRACT:
A flexible caulk tube nozzle that includes a tapered nozzle end portion, an accordion flexible section, a caulk tube attachment portion, and a number of angled caulk tube gripping structures. The tapered nozzle end portion, the accordion flexible section, and the caulk tube attachment portion are integrally formed to define an internal caulk passageway through the tapered nozzle end portion, the accordion flexible section and the caulk tube attachment portion. The caulk tube attachment portion defines a caulk tube insertion opening in connection with the internal caulk passageway. Each of the plurality of angled caulk tube gripping structures has a bevel edged internal caulk tube engaging portion that extends into the internal caulk passageway adjacent to the caulk tube insertion opening in a manner such that as the flexible caulk tube nozzle is screwed onto a caulk tube, the bevel edged internal caulk tube engaging portions each cut into and engage the caulk tube.
