## Abstract

An apparatus and a method are provided for a sprayer nozzle support to a pump mechanism of a trigger sprayer assembly. The sprayer nozzle support generally comprises a tower portion and a first and second side protrusions. The tower portion is configured to convey stability to the pump mechanism when a screw cap of the trigger sprayer assembly is screwed onto a neck of a container. A top of the tower portion is configured to support the pump mechanism and a bottom of the tower portion is configured to contact the screw cap. The first and second side protrusions provide structures whereby the sprayer nozzle support may be removed from the trigger sprayer assembly. A curved proximal surface of the tower portion and the first and second side protrusions facilitates an unobstructed grasping of the trigger sprayer assembly in a hand.

## Claims

### Claim 1

An apparatus for providing support to a pump mechanism of a trigger sprayer assembly, comprising a trigger operated piston moving within a cylinder, the apparatus comprising:
a tower portion including:
(i) a top portion including a raised channel configured to support a cylinder, and
(ii) a bottom portion being configured to contact a screw cap wherein the at least a top of the tower portion being configured to support the cylinder, and a bottom of the tower portion being configured to contact the screw cap;
a first side protrusion positioned on a first side of the tower portion;
a second side protrusion positioned on a second side of the tower portion opposite the first side; and
a curved proximal surface bounding the tower portion, the first side protrusion and the second side protrusion, wherein the raised channel further comprises a flat strip configured to facilitate removal of the apparatus from the trigger sprayer assembly, the flat strip comprising an edge of the raised channel being relatively lower to an opposing edge of the raised channel.

### Claim 2 (depends on 1)

The apparatus of claim 1, wherein the first side protrusion and the second side protrusion are configured to maintain the tower portion positioned between the screw cap and the cylinder.

### Claim 3 (depends on 1)

The apparatus of claim 1, wherein the raised channel is further configured to interface with an exterior of the cylinder.

### Claim 4 (depends on 3)

The apparatus of claim 3, wherein the raised channel further comprises a rounded cross-sectional shape including a radius which substantially matches an exterior radius of the cylinder.

### Claim 5 (depends on 1)

The apparatus of claim 1, wherein the flat strip further comprises a rounded edge to further facilitate installation and removal of the apparatus from the trigger sprayer assembly.

### Claim 6 (depends on 3)

The apparatus of claim 3, wherein the raised channel is further configured with an upward angle in passing from a curved proximal surface to a flat distal surface, the upward angle being substantially equal to an angle between the cylinder and a top of the screw cap.

### Claim 7 (depends on 1)

The apparatus of claim 1, wherein each of the first side protrusion and the second side protrusion comprises a curved distal surface configured to reduce interference with components and structures within the trigger sprayer assembly.

### Claim 8 (depends on 7)

The apparatus of claim 7, wherein the curved distal surfaces also facilitate removal of the apparatus from the trigger sprayer assembly.

### Claim 9 (depends on 1)

The apparatus of claim 1, wherein the tower portion is fabricated as a extension of the cylinder, such that the tower portion supports the cylinder when the screw cap of the trigger sprayer assembly is screwed onto the neck of the container.
