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 dispersing 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 dispenser, comprising:
a base, comprising:
an inlet;
a base seal seat in fluid communication with the inlet; and
a base valve sleeve seat;

a seal seated on the base, comprising:
a seal edge about an outer periphery portion of the seal; and
a flow passage in fluid communication with the inlet;

a dispenser head seated on the base and over the seal, wherein an interior wall of the dispenser head is in contact with the seal edge and the dispenser head is moveable variably between a first position and a second position;
a dosing chamber defined by an interior of the dispenser head and the seal, wherein the dosing chamber is in fluid communication with the flow passage, wherein the dosing chamber has a variable volume depending upon the movement of the dispensing head, the dosing chamber configured and arranged to hold a user-selected, measured volume of a fluid depending on the position of the dispensing head;
a valve sleeve mounted to the base, comprising:
an interior volume in fluid communication with the flow passage;
a first opening at a first end of the valve sleeve; and
a valve seat adjacent a second opening opposite the first opening;

a valve seated at least partially in the valve seat, the valve comprising:
an inlet valve seated against the base about the inlet;
an outlet valve seated in the valve seat; and

a cap mounted to the base, wherein said cap encloses portions of the dispensing head, seal and base.

2. The dispenser of claim 1 , wherein the base further comprises:
a base platform;
a skirt projecting off of and away from the base platform;
at least one base projection on the skirt;
a base support wall extending away from the base platform in a direction opposite the skirt; and
wherein the base seal seat is in an interior of the volume defined by the base support wall.

3. The dispenser of claim 1 , wherein the dispenser head further comprises a lever movable relative to the cap.

4. The dispenser of claim 3 , further comprising at least one lever path in the cap, wherein the lever may move along the at least one lever path.

5. The dispenser of claim 1 , further comprising:
a lever connected to the dispenser head;
a first lever path in the cap;
a second lever path in the cap, wherein the second lever path is longer than the first lever path; and
wherein the dispenser head is rotationally movable to align the lever with the first lever path, the second lever path, or a stop and is longitudinally moveable along the first lever path or the second lever path.

6. The dispenser of claim 5 , wherein movement of the lever along the entire length of the first lever path changes the volume of the dosing chamber to a first volume and movement of the lever along the entire length of the second lever path changes the volume of the dosing chamber to a second volume which is greater than the first volume.

7. The dispenser of claim 1 , wherein the dispenser head may be moved away from the base to increase the volume of the dosing chamber and towards the base to decrease the size of the dosing chamber.

8. The dispenser of claim 1 , further comprising graduated markings on the dispenser head.
