Abstract

Embodiments of the invention relate to dosing dispensers and in particular to dosing dispensers that may be operated using one hand by raising and filling a dosing chamber followed by lowering and dispensing a product from the dosing chamber and wherein the dose may be selected or adjusted and a user may visually confirm that the proper dose is being loaded and delivered by the dispenser.

First claim

What is claimed is:

1. A dispensing device, comprising:
a container comprising an opening and an internal volume; a dispenser fixed about the opening of the container, the dispenser comprising;
a base secured to said container and having an inlet and an outlet, and a dispensing nozzle extending from the outlet;
a shroud including a cap portion received about the base and a spout portion received about the dispensing nozzle; and
a dispenser head having a transparent or translucent dosing chamber portion at least partially defined by an interior of the dispenser head, wherein the dosing chamber has at least a first volume when the dispenser head is nearest the container and a second volume when the dispenser head is moved in a vertical direction away from the container, the second volume being greater than the first volume;
said dosing chamber portion extending through said cap portion of said shroud, wherein said dispenser head is movable in a direction away from the container and in a direction toward the container;
said dispenser head including a lever portion projecting radially outward through a gap in said cap portion of said shroud wherein said lever is operable for moving said dispenser head in an axial direction away from and towards said container;
said cap portion of said shroud including at least one guide path for guiding movement of said lever portion of said dispenser head for dispensing either said first volume or said second volume.

2. The dispensing device of claim 1 , further comprising a product in the container, wherein movement of the dispenser head in the direction away from the container draws product into the dosing chamber.

3. The dispensing device of claim 2 , wherein movement of the dispenser head in the direction towards the container pushes product in the dosing chamber out of the dispenser.

4. The dispensing device of claim 1 , further comprising graduated markings on the dispenser head.

5. The dispensing device of claim 1 , further comprising a dip tube connected to the dispenser and extending into the internal volume of the container.

6. The dispensing device of claim 1 , further comprising a piston in the container.

7. The dispensing device of claim 6 , further comprising a window in at least a portion of the container through which at least a portion of the piston is visible.

8. The dispensing device of claim 7 , further comprising graduated markings on the container.

9. The dispensing device of claim 1 further comprising a valve disposed within said dispensing nozzle.

10. The dispensing device of claim 9 , wherein said valve includes a valve head comprising a flexible disc portion seated in the base and a stem portion extending into said dispensing nozzle.

11. The dispensing device of claim 9 , further comprising a piston in the container.

12. The dispensing device of claim 9 , further comprising a window in at least a portion of the container through which at least a portion of the piston is visible.

13. The dispensing device of claim 10 , further comprising a piston in the container.

14. The dispensing device of claim 10 , further comprising a window in at least a portion of the container through which at least a portion of the piston is visible.
