Abstract

A ready-to-use sprayer comprises a container defining an interior compartment for containing a liquid product and having a pin receiver located near the rear portion and an opening located near the front portion, a housing having a main chamber and a grip portion, a nozzle in selective fluid communication with the outlet of the fluid chamber, a pivot switch on the exterior of the housing for selecting a fluid flow condition for the main chamber, and the housing being coupled to the container at the container opening and the pin receiver.

First claim

What is claimed is:

1. A sprayer comprising:
a container defining an interior compartment for containing a substance liquid, the container comprising a front portion, a rear portion, and a pin receiver on the rear portion, the container further defining a container opening in the front portion;
a housing comprising a grip portion, a main chamber, and a carrier liquid receiving port, and a carrier liquid conduit, wherein the grip portion defines a grip portion chamber extending at least between the carrier liquid receiving port and the main chamber, the carrier liquid conduit being coupled to the carrier liquid receiving port and extending through the grip portion chamber to the main chamber;
a substance liquid conduit in selective fluid communication with the container and with the main chamber;
a pivot switch on an exterior of the housing for selecting a fluid flow condition for the main chamber; and
a pivot arm operatively coupled to the pivot switch to translate movement of the pivot switch to the main chamber, the pivot arm being pivotally connected to a pivot axis, the pivot axis being located to a rear of the substance liquid conduit,
wherein the pivot switch is operatively coupled to the pivot arm to translate movement of the pivot switch, through an arcuate path, to the main chamber and the pivot axis is located below the main chamber; and
wherein the housing is coupled to the container at two separate points comprising: the container opening and the pin receiver.

2. The sprayer of claim 1 , wherein the front portion is elevated with respect to the rear portion.

3. The sprayer of claim 1 , further comprising a pin, wherein the pin is inserted through the pin receiver to couple the housing to the container at the pin receiver.

4. The sprayer of claim 3 , wherein the pin is formed as part of the housing.

5. The sprayer of claim 3 , wherein the pin receiver receives an outside portion of the pin.

6. The sprayer of claim 3 , wherein the housing and the container are removably coupled through the pin and the pin receiver.

7. The sprayer of claim 1 , wherein the grip portion is curved and the main chamber comprises a substance liquid inlet, a carrier liquid inlet located to a rear of the substance liquid inlet, and an outlet located to a front of the substance liquid inlet; and the housing further comprises: a nozzle in selective fluid communication with the outlet of the main chamber, wherein the housing is coupled to the container opening at the substance liquid inlet.

8. The sprayer of claim 1 , wherein the grip portion and the pivot switch are positioned so that a user can hold the sprayer and move the pivot switch with one hand.

9. The sprayer of claim 1 , wherein the carrier liquid conduit has a first end and a second end, the first end being coupled to the carrier liquid receiving port and the second end being coupled to carrier liquid inlet, the carrier liquid conduit being in selective fluid communication with the main chamber at the carrier liquid inlet.

10. The sprayer of claim 9 , wherein the pivot switch controls a flow of a carrier liquid and the substance liquid into the main chamber.

11. The sprayer of claim 9 , wherein the main chamber is configured to generate a vacuum to enable mixing of a carrier liquid and the substance liquid.

12. The sprayer of claim 1 , wherein the main chamber comprises:
a rear chamber;
a middle chamber; and
a front chamber.

13. The sprayer of claim 12 , wherein the rear chamber, the middle chamber, and the front chamber have different dimensions.

14. The sprayer of claim 12 , wherein the main chamber is configured so that the mixing of a carrier liquid and the substance liquid occurs within the front chamber.

15. The sprayer of claim 1 , wherein the main chamber comprises three operating positions, the three operating positions comprising:
a first operating position, wherein the main chamber is not in fluid communication with either the carrier liquid conduit or the substance liquid conduit;
a second operating position, wherein the main chamber is in fluid communication with both the carrier liquid conduit and the substance liquid conduit; and
a third operating position wherein the main chamber is fluid communication with the carrier liquid conduit but not with the substance liquid conduit.

16. The sprayer of claim 1 , wherein the pivot switch comprises a top end that is movable from a first position in front of the pivot axis to a second position to a rear of the pivot axis.

17. A sprayer comprising:
a container defining an interior compartment for containing a substance liquid; the container comprising a front portion, a rear portion, and a pin receiver on the rear portion, the container further defining a container opening in the front portion;
a housing comprising:
a curved grip portion,
a main chamber comprising a substance liquid inlet, a carrier liquid inlet, and an outlet,
a carrier liquid receiving port, wherein the curved grip portion defines a curved grip portion chamber extending at least between the carrier liquid receiving port and the main chamber,
a carrier liquid conduit, the carrier liquid conduit being coupled to the carrier liquid receiving port and extending through the curved grip portion chamber to the carrier liquid inlet of the main chamber, and
a nozzle in selective fluid communication with the outlet of the main chamber;
a substance liquid conduit in selective fluid communication with the container and with the main chamber; and
a pivot switch having three operating positions, the pivot switch being located on an exterior of the housing for selecting a fluid flow condition for the main chamber, wherein the pivot switch is operatively coupled to a pivot arm to translate movement of the pivot switch, through an arcuate path, to the main chamber and the pivot arm is pivotally connected to a pivot axis, the pivot axis being located below the main chamber and to a rear of the substance liquid conduit,
wherein the housing is coupled to the container at the container opening through the substance liquid inlet and at the pin receiver through a pin inserted through the housing and the pin receiver.

18. The sprayer of claim 17 , wherein, when the main chamber moves from a first operating position to a second operating position or a third operating position, the pivot switch moves forward towards the front portion of the container.

19. The sprayer of claim 18 , wherein, when the pivot switch moves from one of the three operating positions in which the main chamber is not in fluid communication with the carrier liquid conduit to another of the three operating positions in which the main chamber is in fluid communication with the carrier liquid conduit, the pivot switch moves forward towards the front portion of the container.
