Abstract

A fluid delivery system for dispensing fluid can include a dispenser ( 10 ), such as a trigger engine-type dispenser, configured to draw fluid up from a container to dispense a foam-like spray. The dispenser ( 10 ) can be configured to draw fluid up from a container. A dispenser body can be configured to mount the dispenser to the container. The dispenser can include a nozzle (N) having an orifice ( 230 ), and a mesh (M) material can be placed on the nozzle (N) over the orifice ( 230 ). The mesh (M) material can be formed of a polymeric material in one example, and in another example, the mesh material can be formed of a stainless steel material. A method of assembling a dispenser configured to draw fluid up from a container is also disclosed, which can include providing a dispenser body configured to mount the dispenser to the container, securing a nozzle having an orifice to the dispenser body, and securing a mesh material to the nozzle.

First claim

1 . A fluid delivery system for dispensing fluid comprising:
a housing having an inlet portion and an outlet portion; a pump including a trigger lever associated with the housing and being configured to draw fluid up from a container; a coupling provided at the inlet portion and configured to secure the housing to the container; and a nozzle provided at the outlet portion comprising an orifice and a mesh material configured to be placed over the nozzle for a foam dispensing mode and configured to be removable from the nozzle for a spray dispensing mode.

2 . The fluid delivery system of claim 1 wherein the mesh material is formed of one of a polymeric material or a stainless steel material.

3 . The fluid delivery system of claim 1 wherein the nozzle further comprises a recess and wherein the recess houses the orifice and wherein the mesh material covers the recess.

4 . The fluid delivery system of claim 3 wherein a rim extends from the nozzle and surrounds the orifice to define the recess.

5 . The fluid delivery system of claim 4 wherein the mesh material comprises a flange and wherein the flange is configured to engage the rim to secure the mesh material to the nozzle.

6 . The fluid delivery system of claim 1 wherein the mesh material is connected to the nozzle by one of a snap fit, a hinge, or combination thereof.

7 . The fluid delivery system of claim 1 wherein the mesh material is provided with a curved shape.

8 . The fluid delivery system of claim 1 wherein the nozzle and the mesh material are configured to provide a foam having a length of greater than 16 inches and a width of greater than 2 inches when dispensed from a distance of 15 inches from a surface.

9 . A fluid delivery system for dispensing fluid comprising:
a housing having an inlet portion and an outlet portion; a pump including a trigger lever associated with the housing and being configured to draw fluid up from a container; a coupling provided at the inlet portion and configured to secure the housing to the container; and a nozzle provided at the outlet portion comprising an orifice and a curved mesh material covering the nozzle; wherein the curved mesh material together with the nozzle are configured to provide a foam.

10 . The fluid delivery system of claim 9 wherein the mesh material is provided with a concave or convex shape.

11 . The fluid delivery system of claim 9 wherein the mesh material is formed with a constant radius of curvature.

12 . The fluid delivery system of claim 9 wherein a distance from a center of the nozzle to the mesh material is greater than a distance from a perimeter of the nozzle to the mesh material.

13 . The fluid delivery system of claim 9 wherein a distance from a center of the nozzle to the mesh material is less than a distance from a perimeter of the nozzle to the mesh material.

14 . The dispenser of claim 9 wherein the mesh material is formed of a polymeric material or a stainless steel material.

15 . The dispenser of claim 9 wherein a rim extends from the nozzle and surrounds the orifice to define a recess and wherein the recess houses the orifice and wherein the mesh material covers the recess.

16 . The dispenser of claim 15 wherein the mesh material comprises a flange and wherein the flange is configured engage the rim to secure the mesh material to the nozzle.

17 . The dispenser of claim 10 wherein the mesh material is connected to the nozzle by one of a snap fit, hinge, an ultra-sonic weld, a heat weld, an adhesive or combination thereof.

18 . The dispenser of claim 10 wherein the nozzle and the mesh material are configured to provide a foam having a length of greater than 16 inches and a width of greater than 2 inches when dispensed from a distance of 15 inches from a surface.

19 . A method of assembling a dispenser configured to draw fluid up from a container comprising:
providing a housing having an inlet portion and an outlet portion; providing a pump including a trigger lever associated with the housing and configuring the pump to draw fluid up from a container; providing a coupling at the inlet portion and configured to secure the housing to the container; providing a nozzle at the outlet portion comprising an orifice and placing a mesh material over the orifice of the nozzle; and configuring the nozzle and the mesh material to provide a foam having a length of greater than 16 inches and a width of greater than 2 inches when dispensed from a distance of 15 inches from the surface desired to be cleaned.

20 . The method of claim 19 further comprising forming the mesh material of one of a polymeric material or a stainless steel material.

21 . The method of claim 19 further comprising forming a rim defining a recess on an end of the nozzle and wherein the mesh material covers the recess.

22 . The method of claim 19 further comprising connecting the mesh material to the nozzle by one of a snap fit, hinge, an ultra-sonic weld, a heat weld, an adhesive or combination thereof.

23 . A fluid delivery system for dispensing fluid comprising:
a housing having an inlet portion and an outlet portion; a pump including a trigger lever associated with the housing and being configured to draw fluid up from a container; a coupling provided at the inlet portion and configured to secure the housing to the container; and a nozzle provided at the outlet portion comprising an orifice and a mesh material covering the nozzle; wherein the nozzle and the mesh material are configured to provide a foam having a length of greater than 16 inches and a width of greater than 2 inches when dispensed from a distance of 15 inches from a surface.
