Abstract

A squeeze sprayer for dispensing fluid product as a spray or spray mist includes a squeeze bottle and a squeeze sprayer closure attached to the squeeze bottle. The squeeze sprayer includes a cap which defines a chamber for receipt of air and fluid and further defines an outlet. Further included as a part of the squeeze sprayer is a valve which is assembled into the cap and a dip tube which is received by the cap. The dip tube is constructed and arranged to provide air to the chamber and the squeezing of the bottle forces air and fluid into the chamber and from there through the outlet to be dispensed as a spray or spray mist. A second embodiment provides an upright squeeze sprayer with a unique orifice cup. A third embodiment includes a directional adapter.

First claim

The invention claimed is:

1. A squeeze sprayer for dispensing fluid product as a spray or spray mist, the squeeze sprayer comprising:
a container;
a cap coupled with the container, the cap comprising an outlet and a chamber for receipt of air and fluid product;
a diaphragm valve coupled with the cap and comprising a fluid passageway to the chamber;
a dip tube coupled to the cap, the dip tube comprising an inner fluid passageway in fluid communication with the chamber, wherein applying pressure to the container forces a first material through the fluid passageway of the valve and forces a second material through the inner fluid passageway of the dip tube; and
wherein the valve includes side walls, a panel, and an opening formed through the panel.

2. The squeeze sprayer of claim 1 wherein the cap has a single-piece construction which includes a sleeve extending from a panel.

3. The squeeze sprayer of claim 2 wherein the sleeve defines the chamber.

4. The squeeze sprayer of claim 2 wherein the sleeve receives the dip tube.

5. The squeeze sprayer of claim 4 , further comprising a fluid channel defined by a portion of an outer surface of the dip tube and a portion of the inner surface of the sleeve.

6. The squeeze sprayer of claim 5 wherein the chamber is in fluid flow communication with the fluid channel.

7. The squeeze sprayer of claim 2 wherein the cap includes a flip-top lid.

8. The squeeze sprayer of claim 1 wherein the cap and valve are coupled via a friction fit.

9. The squeeze sprayer of claim 1 wherein the panel has a different thickness than the side walls.

10. The squeeze sprayer of claim 1 wherein the first material is a fluid and the second material is a gas.
