Nozzle assembly for a dispensing device

Abstract

A nozzle assembly for use with a device for dispensing a flowable material, such as caulking material, is disclosed. The nozzle assembly includes a conduit having an inlet end adapted for connecting to the dispensing device, an outlet end, and a longitudinally extending passage therethrough. A head assembly is arranged to be rotatably mounted to the conduit outlet end. A nozzle is arranged to be affixed within the head assembly, the nozzle comprising a larger diameter inlet opening, a smaller diameter outlet opening, and a tapered wall comprising a notched portion which, together with the outlet opening forms a dispensing opening. The nozzle is arranged to rotate in response to rotation of the head assembly to any one of a plurality of positions for directing a bead of flowable material onto a surface.

1 . A nozzle assembly for use with a device for dispensing a flowable material, said nozzle assembly comprising:
 a. a rigid conduit having an inlet end adapted for connecting to the dispensing device, an outlet end, and a passage extending therethrough, said conduit including a first straight section that extends from said inlet end to a bend and a second straight section that extends from said bend to said outlet end; and,   b. a rotatable head assembly arranged to be connected to the outlet end of said rigid conduit, said head assembly comprising a nozzle having a larger diameter inlet opening, a smaller diameter outlet opening, and a tapered wall, said nozzle tapered wall comprising a single notch extending proximally from said nozzle outlet opening, said outlet opening and said single notch together forming a dispensing opening arranged for dispensing a bead of flowable material, the direction of dispensing of flowable material through said dispensing opening being alterable by rotation of said head assembly during dispensing, said head assembly arranged to rotate in response to manual actuation to any one of a plurality of positions.
