Abstract

A dispensing assembly and method for dispensing a mixture of a first fluid component and a second fluid component. The dispensing assembly generally comprises a container coupled with a nozzle in a unique manner to achieve a mechanical and fluid connection. More specifically, the container includes a first chamber and a second chamber. The first and second chambers are adapted to respectively hold the first and second fluid components. The nozzle has an inlet end and an outlet end. First and second connecting elements are located at the inlet end of the nozzle. Another mating pair of connecting elements, i.e., third and fourth connecting elements, of the container respectively communicate with the first and second chambers. The first and second connecting elements are respectively capable of being removable coupled to the third and fourth connecting elements to establish fluid paths from the first and second chambers into the inlet end of the nozzle. A coupling element selectively couples the inlet end of the nozzle to the container.

First claim

What is claimed is:

1. A dispensing assembly for dispensing a fluid, comprising:
a container including a chamber for holding at least one component of the fluid;
a nozzle having an inlet end and an outlet end;
first connecting element at the inlet end of the nozzle;
second connecting element associated with the container and communicating with the chamber, the first connecting element and the second connecting element capable of being removably coupled to each other to establish a fluid path from the chamber into the inlet end of the nozzle;
a coupling element operative to selectively couple the inlet end of the nozzle to the container; and
support structure including an upstanding rail extending from the container and having a generally T-shaped cross-section;
wherein the coupling element further comprises a slide element carried for sliding movement along the support structure on the container, the slide element including a flange engaging the rail for guiding the movement of the slide element along the rail and being slidable between locked position and unlocked position, wherein the nozzle is capable of being decoupled from the container when the slide element is in the unlocked position.

2. The dispensing assembly of claim 1 , wherein the first connecting element is part of a unitary insert positioned between the inlet end of the nozzle and the second connecting element.

3. The dispensing assembly of claim 1 , wherein the slide element is U-shaped and includes an open end and a closed end, the open end receiving and coupling to the inlet end of the nozzle when in the locked position.

4. The dispensing assembly of claim 3 , wherein the inlet end of the nozzle includes a flange and the U-shaped slide element includes a recess receiving the flange to couple the U-shaped slide element to the inlet end of the nozzle in the locked position.

5. The dispensing assembly of claim 1 , wherein the first connecting element and the second connecting element are respectively sized and configured to be coupled together with a friction fit.

6. A dispensing assembly for dispensing a mixture of a first fluid component and a second fluid component, comprising:
a container including a first chamber and a second chamber, the first chamber and the second chamber adapted to respectively hold the first fluid component and the second fluid component;
a nozzle having an inlet end and an outlet end;
first connecting element and second connecting element at the inlet end of the nozzle;
third connecting element and fourth connecting element associated with the container and respectively communicating with the first chamber and the second chamber, the first connecting element and the second connecting element respectively capable of being removably engaged with a frictional fit to the third connecting element and the fourth connecting element to establish respective, independent fluid paths from the first chamber and the second chamber into the inlet end of the nozzle; and
a non-rotatable coupling element movable in a linear manner between locked position and unlocked position to selectively couple the inlet end of the nozzle to the container,
wherein the non-rotatable coupling element further comprises a slide element capable of sliding along a support structure extending from the container, the slide element slideable in a linear manner to engage the support structure and the inlet end of the nozzle when the slide element is in the locked position.

7. The dispensing assembly of claim 6 , wherein the first connecting element and the second connecting element are part of a unitary insert positioned generally between the inlet end of the nozzle and the third connecting element and the fourth connecting element.

8. The dispensing assembly of claim 6 , wherein the non-rotatable coupling element further comprises a slide element carried for sliding movement along support structure on the container, the slide element slidable in a linear manner between the locked position and unlocked positions, wherein the nozzle is capable of being decoupled from the container when the slide element is in the unlocked position.

9. The dispensing assembly of claim 8 , wherein the slide element is U-shaped and includes an open end and a closed end, the open end receiving and coupling to the inlet end of the nozzle when in the locked position.

10. The dispensing assembly of claim 9 , wherein the inlet end of the nozzle includes a flange and the U-shaped slide element includes a recess receiving the flange to couple the U-shaped slide element to the inlet end of the nozzle in the locked position.

11. The dispensing assembly of claim 8 , wherein the support structure further comprises an upstanding rail extending from the container and having a T-shaped cross-section, the slide element including a flange engaging the rail for guiding the movement of the slide element along the rail.

12. The dispensing assembly of claim 6 , wherein the first connecting element and the second connecting element are respectively sized and configured to be received with a friction fit within the third connecting element and the fourth connecting element.

13. The dispensing assembly of claim 6 , further comprising a static mixer element in the nozzle for mixing the first fluid component and the second fluid component prior to dispensing a mixture of the first fluid component and the second fluid component from the outlet end.

14. The dispensing assembly of claim 6 , wherein the first connecting element, the second connecting element, the third connecting element and the fourth connecting element respectively further comprise first projecting tube, second projecting tube, third projecting tube and fourth projecting tube, and wherein the first projecting tube and the third projecting tube are capable of being frictionally fit together and the second projecting tube and fourth the projecting tube are capable of being frictionally fit together to establish the respective, independent fluid paths.

15. A dispensing assembly for dispensing a mixture of a first fluid component and a second fluid component, comprising:
a container including a first chamber and a second chamber, the first chamber and the second chamber adapted to respectively hold the first fluid component and the second fluid component;
a nozzle having an inlet end and an outlet end;
first connecting element and second connecting element coupled to each other at the inlet end of the nozzle;
third connecting element and fourth connecting element associated with the container and respectively communicating with the first chamber and the second chamber, the first connecting element and the second connecting element respectively capable of being removably engaged with a frictional fit to the third connecting element and the fourth connecting element to establish respective, independent fluid paths from the first chamber and the second chamber into the inlet end of the nozzle;
a rail carried by the container and connected to the third connecting element and the fourth connecting element; and
a non-rotatable coupling element carried for sliding movement in a linear manner on the rail between locked position and unlocked position, the non-rotatable coupling element operative to selectively couple the inlet end of the nozzle to the container when in the locked position and allowing the nozzle to be removed from the container when in the unlocked position.

16. The dispensing assembly of claim 15 , wherein the first connecting element and the second connecting element are part of a unitary insert positioned bet
