Abstract

The present invention is a chemical dispenser, preferably for dispensing chlorine or bromine to pools, spas, and hot tubs. The preferred embodiment is a buoyant vessel connected to a sea creature-shaped dispenser vessel by a line, where the sea creature-shaped dispenser vessel has a buoyant shell and a cargo chamber that has an insertion port and a permeable surface with a plurality of dissolution ports.

Claims

1. A chemical dispenser for a body of water, comprising:

a buoyant flotation vessel floating on the body of water;

a dispenser vessel, with a buoyant shell having an insertion port and a permeable surface encapsulating a cargo chamber, the dispenser vessel adapted to float on the body of water when empty, and to submerge below the surface of the body of water when an amount of chemical is added to the cargo chamber; and

a line of predetermined length connecting the buoyant vessel on ton of the water to the submerged dispenser vessel, the line and buoyant shell preventing the dispenser vessel from sinking to the bottom of the body of water when the chemical is added to the dispenser vessel.

2. The chemical dispenser of claim 1 wherein the permeable surface comprises a plurality of dissolution ports.

3. The chemical dispenser of claim 1 wherein the dispenser vessel is shaped like a sea creature.

4. The chemical dispenser of claim 1 wherein the permeable surface is permeable to water.

5. The chemical dispenser of claim 4 wherein the permeable surface is permeable to chlorine.

6. The chemical dispenser of claim 4 wherein the permeable surface is permeable to bromine.

7. A chemical dispenser for a body of water comprising:

a buoyant flotation vessel floating on the body of water

a dispenser vessel having a buoyant chamber and a cargo chamber, said cargo chamber having an insertion port and a permeable surface, the dispenser vessel adapted to float on the body of water when empty, and to submerge below the surface of the body of water when an amount of chemical is added to the cargo chamber; and

a line of predetermined length connecting the buoyant vessel on top of the water to the dispenser vessel under the water, the line and buoyant vessel preventing the dispenser vessel from sinking to the bottom of the body of water when the chemical is in the dispenser vessel.

8. The chemical dispenser of claim 7 wherein the permeable surface comprises a plurality of dissolution ports.

9. The chemical dispenser of claim 7 wherein the permeable surface is permeable to water.

10. The chemical dispenser of claim 7 wherein the permeable surface is permeable to chlorine.

11. The chemical dispenser of claim 7 wherein the dispenser vessel is shaped like a sea creature.

12. A chemical dispenser for a body of water comprising:

a buoyant floatation vessel floating on the body of water

a sea creature-shaped dispenser vessel having a head section and a body section, the body section including a plurality of dissolution ports, the dispenser vessel adapted to float on the body of water when empty, and to submerge below the surface of the body of water when an amount of chemical is added to the body section; and

a line of predetermined length connecting the buoyant vessel on top of the water to the dispenser vessel under the water, the line and buoyant vessel preventing the dispenser vessel from sinking to the bottom of the body of water when full of chemical.

13. The chemical dispenser of claim 12 wherein the chemical is water soluble, and as the chemical dissolves in water the submerged dispenser vessel rises.

14. The chemical dispenser of claim 12 wherein the submerged dispenser vessel rises to the surface of the body of water as the chemical becomes depleted.
