Abstract

A fluid sprayer comprises a fluid source, a spray nozzle, a pump, and a handle with a base. The spray nozzle is disposed to accept a spray tip with an outlet aperture. The pump is disposed to pump fluid from the fluid source out the outlet aperture of the spray tip. The base has a sealable storage slot sized to contain and form an air seal with the spray tip when not in use.

First claim

The invention claimed is:

1. A fluid sprayer comprises:
a fluid source;
a spray nozzle disposed to accept a spray tip with an outlet aperture;
a pump disposed to pump fluid from the fluid source out the outlet aperture of the spray tip;
a handle with a base; and
a sealable storage slot in the base, sized to contain and form an air seal with the spray tip when not in use,
wherein the sealable storage slot is partially covered by a molded layer of flexible material,
wherein the handle and the base are at least partially covered by the molded layer.

2. The fluid sprayer of claim 1 , wherein the fluid tip has a first diameter, and the sealable storage slot has a second diameter greater than the first diameter but less than twice the first diameter.

3. The fluid spray of claim 1 , wherein the molded layer of flexible material is overmolded to partially cover the sealable storage slot.

4. The fluid sprayer of claim 3 , wherein the flexible material is a plastic or elastomer material.

5. The fluid sprayer of claim 3 , wherein the overmolded layer has an aperture allowing the spray tip to be inserted through the overmolded layer into the storage slot.

6. The fluid sprayer of claim 5 , wherein the aperture opens towards the spray nozzle.

7. The fluid sprayer of claim 5 , wherein the overmolded layer forms the seal via an interference fit with the spray tip.

8. The fluid sprayer of claim 7 , wherein the spray tip has a first diameter, and the aperture has a second diameter less than the first diameter but greater than 90% of the first diameter.

9. The fluid sprayer of claim 1 , wherein the handle is formed of a rigid polymer.

10. The fluid sprayer of claim 1 , wherein the spray tip comprises a grip tab situated at one end of a substantially cylindrical insert containing an outlet aperture.

11. A method of storing a spray tip of a fluid sprayer, the method comprising:
aligning the spray tip with an aperture of a storage slot in a base of the fluid sprayer, the aperture being formed through compliant material and having an aperture diameter less than a diameter of the spray tip; and
inserting the spray tip into the aperture, thereby deforming the compliant material to form an air seal of the storage slot via an interference fit,
wherein the compliant material forms a layer at least partially covering a grip and base of the sprayer.

12. The method of claim 11 , wherein the compliant material is elastomer or plastic.
