Abstract

A caulking spout through which caulk may be dispensed from a dispenser into a corner joint at various angles of attack without an accompanying substantial change in the shape of the bead of caulk being dispensed. The spout comprises a body having a neck elongated along a body axis merging with a rounded tip traversing the axis and an outlet orifice formed in the rounded tip to one side of and off the body axis. An inlet orifice is formed in the end of the elongated neck distal the rounded tip. A channel communicates between the inlet and outlet orifices with a first channel portion extending from the inlet orifice along the body axis and merging with a second channel portion which diverges from the body axis and terminates at the outlet orifice.

Claims

1. A caulking spout through which caulk may be dispensed from a dispenser into a corner joint at various angles of attack without an accompanying substantial change in the shape of the bead of caulk being dispensed and with the spout comprising a body elongated along a body axis merging with a rounded tip traversing said axis;

an outlet orifice formed in said rounded tip to one side of and off said body axis;

an inlet orifice formed in the end of said elongated body distal said rounded tip and a channel communicating between said inlet orifice and said outlet orifice with a first channel portion extending from said inlet orifice along said body axis and merging with a second channel portion diverging from said body axis and terminating at said outlet orifice.

2. A caulking spout in accordance with claim 1 wherein said channel first portion is generally conical and tapers inwardly from said inlet orifice towards said rounded tip to receive and snuggly grip a tubular dispenser nozzle positioned therewithin.

3. A caulking spout in accordance with claim 1 wherein said rounded tip is substantially semi-spherical.

4. A caulking spout in accordance with claim 3 wherein the exterior of said body is conical.

5. A caulking spout in accordance with claim 3 wherein said outlet orifice is substantially circular and cantic with respect to said body axis.

6. A caulking spout in accordance with claim 5 wherein said outlet orifice is cantic at an angle between approximately 20°

and 30°

with respect to said body axis.

7. A caulking spout in accordance with claim 1 further comprising index means for locating said outlet orifice.

8. A caulking spout in accordance with claim 7 wherein said index means comprises a rib formed on the side of said rounded tip opposite said outlet orifice.

9. A caulking spout in accordance with claim 1 wherein said body is plastic.

10. A caulking spout in accordance with claim 9 wherein said rounded tip is composed of a softer plastic than said body.
