Abstract
A nozzle for a caulking gun incorporates a resilient portion that is compressed when the trigger of the caulking gun is actuated and resumes its former shape when the trigger is released to expand the internal volume of the nozzle. In one embodiment a resiliently compressible insert is mounted within a conventional nozzle and the insert has a hollow body which has an inlet facing the nozzle inlet and an outlet facing the nozzle outlet and the outlet of the compressible insert is of larger diameter than the inlet of the compressible portion. In another embodiment the nozzle incorporates a resiliently compressible folded flange extending radially of the body portion adjacent to the inlet of the nozzle.
