Claims
- 1. A rinse water additive dispenser comprising
a top enclosing a valve housing and at least one opening to allow fluid communication between the valve housing and external environment; a valve assembly that is retained within the valve housing, said valve assembly comprising a resilient valve and counterweight; and a base releasably connected to the top, said base having walls that define an internal chamber for containing a rinse water additive and an opening for receiving the additive and counterweight.
- 2. The dispenser of claim 1, wherein said valve assembly is allowed to move between closed and open positions.
- 3. The dispenser of claim 1, wherein the resilient valve is a disk valve having a diameter that is greater than the base opening.
- 4. The dispenser of claim 1, wherein when the valve assembly is in the closed position, the resilient valve is located between the top and base preventing fluid communication between the internal chamber and the valve housing.
- 5. The dispenser of claim 1, wherein the resilient valve and counterweight are interconnected by a post, said post having an upper portion that extends beyond the resilient valve into the valve housing.
- 6. The dispenser of claim 5, wherein the valve housing has a retaining member having an opening through which the upper portion of the post extends.
- 7. The dispenser of claim 6, wherein the upper portion of the post has a flange extending from the post, said flange having a dimension greater than the opening of the retaining member.
- 8. The dispenser of claim 1, wherein the resilient valve and counterweight are interconnected by a post having telescoping means.
- 9. The dispenser of claim 1, wherein the top and base have threads for releasably connecting the top and base and means to prevent over rotation of said threads.
- 10. The dispenser of claim 1, wherein the top and base have a tongue and groove for releasably connecting the top and base.
- 11. The dispenser of claim 1, wherein the base has an elliptical cross section.
- 12. The dispenser of claim 1, wherein the top has an elliptical cross section.
- 13. The dispenser of claim 1, wherein the base has means for enabling the viewing of a rinse water additive in the internal chamber.
- 14. The dispenser of claim 1, wherein the base further comprises a protective material affixed to at least a portion of the base.
- 15. The dispenser of claim 1, wherein the base further comprises a protective material affixed to at least a portion of the top.
- 16. The dispenser of claim 1, wherein the counterweight and the base have similar cross sectional shapes.
- 17. The dispenser of claim 1, wherein the valve assembly comprises tapered geometry between the counterweight and the bottom of the valve.
- 18. The dispenser of claim 17, wherein the tapered geometry is formed by a separate part.
- 19. The dispenser of claim 17, wherein the tapered geometry is formed by the manufacture of the counterweight.
- 20. The dispenser of claim 1, wherein the base is formed from two or more parts which are connected together by means selected from the group consisting of snaps, tongue-in-groove, and combinations thereof.
