Abstract

A chlorine dispenser for spas includes a tubular container disposed within a sleeve having one closed end. The container and sleeve form a chamber for receiving the solid chlorine source. The sleeve contains apertures for providing access by water to the solid chlorine source. The sleeve is axially movable along the container, and a locknut engages the container to secure a given position of the sleeve. The container is attached to a foam-filled float, which ensures positive buoyancy of the dispenser in water. The sleeve is ballasted to ensure that the dispenser is vertically disposed in the water.

Claims

1. A reusable device for dispensing a solution derived from a solid into a body of water, comprising:

a tubular container having a closed end and an open end;

a sleeve having one closed end and one open end threadable at the open end thereof onto the open end of the container so that the sleeve and the container define a chamber of variable length for receiving the solid;

apertures in the walls of the sleeve proximately adjacent to the closed end of the sleeve where the degree of closure of the apertures is variable from a fully closed position to a fully open position dependent upon the location of the sleeve axially on the container;

a float member larger in diameter than the container filled with foam attached to the container at the closed end thereof;

ballast contained within the sleeve adjacent the closed end thereof;

the float member, ballast and structure and material of the container and sleeve being cooperatively defined to cause the device to float erect, with the sleeve closed end down, irrespective of the quantity of solid in the chamber and irrespective of the presence or absence of air in the chamber above the open end of the container; and

a nut cooperable between the container and the sleeve for securing the sleeve in a desired location on the container.

2. A device as claimed in claim 1, wherein the float member is hollow and is filled with closed-cell foam material.

3. A device as claimed in claim 1, further comprising indicia on the sleeve for indicating the position of the sleeve on the container.
