Abstract

Claims (21)

1. A fluid dispensing device comprising:

a compressible body for placement within a container, wherein the compressible body compresses responsive to applying compression to the container; and

a substantially hollow fluid traversal body coupled to said compressible body, said fluid traversal body comprising at least one inlet aperture having an inlet valve associated therewith configured to be closed when said compressible body is under compression and to be open when said compressible body is not under compression, said fluid traversal body comprising at least one outlet aperture located outside of the container having an outlet valve associated therewith configured to be open when said compressible body is under compression and to be closed when said compression body is not under compression.

2. The fluid dispensing device of claim 1 wherein said inlet valve comprises an inlet membrane surrounding the substantially hollow fluid traversal body disposed over said at least one inlet aperture.

3. The fluid dispensing device of claim 1 wherein said outlet valve comprises an outlet membrane surrounding the substantially hollow fluid traversal body disposed over said at least one outlet aperture.

4. The fluid dispensing device of claim 1 wherein closing of the inlet valve prevents fluid from flowing into said fluid traversal body and opening the inlet valve enables fluid to flow into said fluid traversal body.

5. The fluid dispensing device of claim 1 wherein closing of the outlet valve prevents fluid from flowing into said fluid traversal body and opening the outlet valve enables fluid to flow into said fluid traversal body.

6. The fluid dispensing device of claim 1 wherein said compressible body is composed of a plastic or polymer.

7. The fluid dispensing device of claim 6 wherein said compressible body includes a compression feature.

8. The fluid dispensing device of claim 7 wherein said compression feature is at least one ridge disposed along an exterior surface of said compressible body.

9. The fluid dispensing device of claim 6 wherein said plastic or polymer is a polyethylene material.

10. A fluid dispensing device comprising:

a container configured for housing a fluid;

a compressible body disposed within the container for dispensing fluid, wherein the compressible body compresses by applying compression to the container;

a substantially hollow fluid traversal body coupled to the compressible body, the fluid traversal body comprising at least one inlet aperture configured to be closed when said compressible body is under compression, said fluid traversal body comprising at least one outlet aperture configured to be open when said compressible body is under compression;

an inlet membrane surrounding the substantially hollow fluid traversal body and disposed over said at least one inlet aperture that acts as an inlet valve; and

an outlet membrane surrounding the substantially hollow fluid traversal body and disposed over said at least one outlet aperture that acts as an outlet valve.

11. The fluid dispensing device of claim 10 wherein closing of the inlet valve prevents fluid from flowing into said fluid traversal body and opening the inlet valve enables fluid to flow into said fluid traversal body.

12. The fluid dispensing device of claim 10 wherein closing of the outlet valve prevents fluid from flowing into said fluid traversal body and opening the outlet valve enables fluid to flow into said fluid traversal body.

13. The fluid dispensing device of claim 10 wherein said compressible body is composed of a plastic or polymer.

14. The fluid dispensing device of claim 10 wherein said compressible body includes a compression feature.
