Abstract

A fluid delivery system for dispensing fluid can include a dispenser, such as a trigger engine-type dispenser, configured to draw fluid up from a container. A nozzle assembly can include a nozzle, and a nozzle slide. The nozzle slide can be configured to slide and/or rotate relative to the shroud to provide different dispensing modes. In alternative examples, the nozzle can be configured to rotate in 30 degree increments relative to the shroud to provide the different dispensing modes or the nozzle assembly can include a nozzle extension, and the nozzle extension can be configured to rotate relative to the shroud to provide different dispensing patterns out of the nozzle. In another example a first nozzle can be configured to provide one or more dispensing modes, and a second nozzle can be configured to provide a different dispensing mode than the first nozzle. Methods of dispensing fluids and methods of assembling fluid dispensers are also disclosed.

First claim

The invention claimed is:

1. A trigger sprayer comprising:
a housing having an inlet portion and an outlet portion;
a pumping mechanism including a trigger lever associated with the housing;
a coupling provided at the inlet portion and configured to secure the housing to a container having a front wall defining a vertical plane; and
a nozzle provided at the outlet portion, the nozzle comprising a tip portion and a slide portion, the slide portion being configured to be selectively moveable by a user between a first position in which the tip portion does not extend beyond the vertical plane defined by the front wall of the container and a second position in which at least a portion of the tip portion extends beyond the vertical plane defined by the front wall of the container and the slide portion being configured to rotate relative to the housing into an off position; and;
wherein the nozzle provides a first dispensing mode in the first position and a second dispensing mode in the second position that is different than the first dispensing mode;
wherein the slide portion comprises an outer rim and the outer rim limits the movement of the slide valve in the rear direction within a slot located in the housing.

2. The trigger sprayer of claim 1 wherein the slide portion rotates 30 degrees relative to the housing to achieve the off position.

3. The trigger sprayer of claim 1 wherein the slot receives and guides a handle of the slide portion and provides for sliding movement of the slide portion along the length of the housing.

4. The trigger sprayer of claim 1 wherein the slide portion moves linearly in a forward direction between the first position and a second position.

5. A fluid delivery system for dispensing fluid comprising:
a dispenser configured to draw fluid up from a container,
a nozzle assembly comprising a first nozzle,
a means for effectively extending the nozzle length to provide at least one dispensing mode,
a slit valve, and
a nozzle insert comprising at least one nozzle insert spray channel and wherein the slit valve comprises at least one slit valve spray channel.

6. The fluid delivery system of claim 5 wherein when the nozzle extends, the nozzle moves relative to the slit valve, the nozzle slide is configured to move to a first position to provide a spray pattern and a second position to provide a stream pattern, wherein in the first position the nozzle is located at a first distance away from the slit valve and in the second position the nozzle is located at a second distance away from the slit valve and wherein the second distance is greater than the first distance.

7. The fluid delivery system of claim 5 wherein the dispenser is a trigger engine.

8. The fluid delivery system of claim 5 wherein the nozzle assembly further includes a second nozzle configured to provide a second dispensing mode different from a first dispensing mode of the first nozzle.

9. A fluid delivery system for dispensing fluid comprising:
a dispenser configured to draw fluid up from a container,
a nozzle assembly comprising a first nozzle,
a nozzle slide for effectively extending the nozzle length to provide at least one dispensing mode, and
a shroud configured to mount to the dispenser
wherein the nozzle system further comprises a nozzle extension, and wherein the nozzle extension is configured to rotate relative to the shroud to provide different spray patterns out of the nozzle.

10. The fluid delivery system of claim 9 wherein the nozzle extension further comprises a tube.

11. A method of assembling a fluid delivery system comprising:
filling a container with a fluid, the container having a front wall defining a vertical plane;
coupling a trigger sprayer to the container, the trigger sprayer comprising:
a housing having an inlet portion and an outlet portion;
a pumping mechanism including a trigger lever associated with the housing;
a coupling provided at the inlet portion and configured to secure the housing to a container having a front wall defining a vertical plane; and
a first nozzle provided at the outlet portion and configured to be selectively moveable by a user between a first position in which the first nozzle does not extend beyond the vertical plane defined by the front wall of the container and a second position in which at least a portion of the first nozzle extends beyond the vertical plane defined by the front wall of the container.

12. The method of assembling a fluid delivery system of claim 11 further comprising a second nozzle configured to slide to provide a second dispensing mode different from a first dispensing mode of the first nozzle.

13. The method of assembling a fluid delivery system of claim 12 further comprising a nozzle adapter configured to selectively provide fluid to the first nozzle and the second nozzle.

14. The method of assembling a fluid delivery system of claim 13 wherein the nozzle adapter comprises a first passageway and a second passageway and wherein the first passageway is configured to provide fluid to the first nozzle and the second passageway is configured to provide fluid to the second nozzle.

15. The method of assembling a fluid delivery system of claim 12 further comprising providing a stop on the first nozzle wherein the first stop prevents the second nozzle from sliding to an open position when the first nozzle is in a dispensing mode.

16. The method of assembling a fluid delivery system of claim 11 applying a shrink sleeve label to the container by passing the shrink sleeve label over the trigger sprayer while the first nozzle is in the first position.
