Abstract
A tool that allows a user to salvage a tube of caulk after the nozzle has become clogged. The approach is to cut off the nozzle to leave a stub of sufficient length, tap threads into the stub, and screw in a replacement nozzle. The tool comprises a body having a generally semi-cylindrical recess conforming to the base region of the caulking tube nozzle. A blade is mounted in the recess for cutting of the nozzle at a predetermined distance from the base of the nozzle. A tap, suitable for cutting threads into the stub of the nozzle, is rigidly mounted to and protrudes from the body. The tool includes provision for rendering the blade ineffective to cut nozzles or fingers when the tool is being used other than in the cutting mode.

A tool for allowing a user to replace the nozzle on a caulking tube, comprising:
- a body;
- a blade mounted to said body;
- guard means for selectively exposing said blade;
- means adapted to contact the caulking tube, for positioning said blade, when exposed, relative to said nozzle to enable cutting the nozzle so as to leave a stub of predetermined length;
- and
- a tap sized to cut internal threads in the stub, rigidly mounted to said body.
A tool for allowing a user to replace the nozzle on a caulking tube, comprising:
- a body having a flat end face and a peripheral wall, said peripheral wall being formed with a recess sized to accommodate at least a portion of the base region of the nozzle;
- a blade mounted within said recess so that it is in a plane parallel to said end face and spaced a predetermined distance therefrom, said blade having an outwardly pointing edge spaced inwardly from said peripheral wall;
- guard means for selectively exposing said blade, said guard means and said blade being relatively movable from a first position where said recess extends along said peripheral wall with said blade edge exposed to enable cutting the nozzle so as to leave a stub, and a second position wherein said recess is interrupted so that said blade edge is not exposed;
- and
- a tap sized to cut internal threads in the stub, mounted to and extending outwardly from said body.
A tool for allowing a user to replace the nozzle on a caulking tube, comprising:
- a body having first and second faces and having first and second plate-like portions, relatively rotatable about an axis and abutting along an interface plane perpendicular to said axis, each of said plate-like portions being formed with a generally semi-cylindrical cutout in its periphery;
- said body portions having a first relative position with the respective cutouts aligned and a second position with the respective cutouts out of alignment;
- a blade mounted to one of said body portions generally parallel to said interface plane, said blade being spaced inwardly from the periphery;
- and
- a tap mounted rigidly to one of said body portions and extending along said axis out from said second face.
