Abstract

A coating dispensing cartridge and spout therefor, includes a device defining a guide surface co-planar with the exit end of the spout orifice, to enable the user to press the guide surface flat against the surface to be coated and to maintain it thereagainst, as the cartridge is moved therealong.

Claims

1. A spout for dispensing flowable materials from a container to coat a surface, comprising:

a nozzle connected at one of its ends in fluid communication with the container and having means defining an orifice at its opposite end inclined at an angle relative to the axis of the nozzle, said nozzle being substantially tubular, a single guide means extending transversely from one side of said nozzle;

the entire surface contacting end of said guide means being generally flat with a guide surface inclined at an angle relative to the axis of the nozzle end disposed adjacent to and substantially co-planar with said angled orifice, whereby said guide means is the primary support of said container with nozzle during a dispensing operation of said container.

2. A spout according to claim 1, wherein said guide means is an enlarged portion of said nozzle.

3. A spout according to claim 2, wherein said enlarged portion includes a transversely extending fin.

4. A spout according to claim 3, wherein said fin extends substantially the entire length of said nozzle.

5. A spout according to claim 3, wherein said fin extends part way along the length of said nozzle.

6. A spout according to claim 3, wherein said fin is generally triangular in shape, one side of which forms said guide surface.

7. A spout according to claim 2, wherein said enlarged portion surrounds the hollow interior of said nozzle, and is generally oval shaped in cross section.

8. A spout according to claim 2, wherein said guide surface is generally triangular in cross sectional shape, said enlarged surface surrounds the hollow interior of said nozzle, and said enlarged surface is generally triangularly shaped in cross section.

9. A spout according to claim 2, wherein said guide surface is generally oval in cross sectional shape, said enlarged surface surrounds the hollow interior of said nozzle, and said enlarged surface is generally oval shaped in cross section.

10. A spout according to claim 1, wherein said spout includes spout thread means and said container includes container thread means for interengaging said spout thread means to connect releasably said spout to said container.

11. A spout according to claim 1, wherein said container includes a squeezable tube.
