Fastener engaging caulking tube nozzle

Abstract

Caulking tube nozzle, having a nozzle portion, with an integral base, and having a lip connecting and extending downwardly therefrom, the lip is intended for inserting within the upper end of the caulking tube, and is threadedly engaged, held by a bayonet lock, or other fastener, therein, so that the nozzle can be held in place during usage, or opened for removal of any hardened material, before usage. The base of the nozzle may also under certain circumstances engage externally of the upper end of the caulking tube.

1 . A caulking tube nozzle, for use at the forward end of a tube of caulking material, and which may be applied to the upper end of the tube as it is cutaway to expose fresh caulking material, during usage, including a tube of caulking material, a nozzle for application to the front of the caulking tube, said nozzle having a forwardly extending nozzle means, and through which a caulking material will be compressed by any caulking gun to force it out the nozzle tip during application, the base of the nozzle integrally formed with a flanged closure, said flanged closure at its approximate outer edge having a downwardly extending sleeve, such sleeve provided for compressing into the interior of the tube of caulking, with a portion of the flange abutting against the upper edge of the caulking tube, to seal it against leakage of caulking material at that location, and said downwardly extending sleeve has external threads applied thereto, and said nozzle and its flanged closure capable of turning into threaded engagement within the inner upper end of the caulking tube during nozzle application.  
   
   
       2 . The caulking tube nozzle of  claim 1  and wherein the interior of the caulking tube includes a length of inner threads, and which complement the threaded sleeve of the nozzle to provide for a threaded engagement between the nozzle and its flanged closure when threaded into the caulking tube after its upper end has been cut to remove any hardened caulk.
