Abstract

A dispensing nozzle for a container having at least two separate compartments and a single neck finish. The dispensing nozzle comprises a hollow shell having an outer surface, an inner surface, a distal end, and a proximal end. At least one partition projects inwardly from the inner surface of the shell, the partitions defining at least two channels within the shell, each channel aligning with a separate compartment of the container. A flange extends radially from the outer surface of the shell, the flange having an upper surface and a lower surface, the lower surface seating against the sealing surface of the container neck. The proximal end of the shell extends beyond the flange and is configured so as to conform to the dimensions of the inner surface of the container neck.

Claims

1. A dispensing nozzle for a container having at least two separate compartments defined by a partition and a single neck, said nozzle comprising:

a hollow shell having an outer surface, an inner surface, a distal end, and a proximal end, said shell defining a fluid discharge passage;

at least one partition projecting inwardly from the inner surface of the shell, said partition defining at least two channels within the shell; and

a flange extending from the outer surface of the shell, said flange having an upper surface and a lower surface, said lower surface configured so as to be able to seat against the neck of the container;

wherein the proximal end of the shell extends beyond the flange such that it is adapted to straddle each partition of the container and such that it forms a seal against an inner face of each separate product compartment of the container.

2. The dispensing nozzle of claim 1 wherein a collar is fitted about the neck of the container, said collar having an upper end and a lower end, the upper end having an inwardly projecting ledge which contacts the upper surface of the flange when the collar is placed on the neck.

3. The dispensing nozzle of claim 1 wherein the container neck and the flange each have opposing undercuts which allow the nozzle to be snap-fit onto the neck.

4. The dispensing nozzle of claim 1 wherein the shell tapers toward the distal end.

5. The dispensing nozzle of claim 1 wherein the shell is closed at the distal end.

6. The dispensing nozzle of claim 1 wherein the at least two channels of the shell meet to form a pre-mixing chamber within the shell.

7. The dispensing nozzle of claim 5 wherein the closed end is a twist open closure.

8. A container having at least two separate compartments defined by a partition and a single neck with a dispensing nozzle, each of the at least two compartments having an inner face, said nozzle comprising:

a hollow shell having an outer surface, an inner surface, a distal end, and a proximal end, said shell defining a fluid discharge passage;

at least one partition projecting inwardly from the inner surface of the shell, said partition defining at least two channels within the shell, each channel aligning with a separate compartment of the container; and

a flange extending radially from the outer surface of the shell, said flange having an upper surface and a lower surface, said lower surface configured so as to be able to seat against the neck of the container;

wherein the proximal end of the shell extends beyond the flange such that it is adapted to straddle each partition of the container and such that it forms a seal against the inner face of each of the at least two compartments of the container.

9. The container of claim 8 wherein a collar is fitted about the neck of the container, said collar having an upper end and a lower end, the upper end having an inwardly projecting ledge which contacts the upper surface of the flange when the collar is placed on the neck.

10. The container of claim 8 wherein the container neck and the flange each have opposing undercuts which allow the nozzle to be snap-fit onto the neck.

11. The container of claim 8 wherein the shell tapers toward the distal end.

12. The container of claim 8 wherein the shell is closed at the distal end.

13. The container of claim 8 wherein the at least two channels of the shell meet to form a pre-mixing chamber within the shell.

14. The container of claim 12 wherein the closed end is a twist open closure.
