Free floating chlorine controlling assembly

Claim 1

A free floating chlorine controlling assembly that continuously exposes a substantial quantity of a soluble agent to the water in either a spa, hot tub, or pool, which agent may be one that tends to increase the chlorine of said water, said assembly including: a. a polymerized resin container that is defined by a cylindrical sidewall that has a closed first end and a second end defined by a ring shaped mouth, said mouth having first threads defined thereon, and a plurality of spaced transverse passages in said container adjacent said second end; b. a closure defined by a ring shaped sidewall that has a first circumferential edge, a web that extends from said first circumferential edge and spans said closure, said web having a first centered opening therein; c. a weight of not greater transverse cross sectional area than said weight, said web having a second centered opening extending transversely therethrough; d. a cup shaped retainer that includes a bottom that has a cylindrical sidewall extending upwardly therefrom, said bottom having a third centered opening therein; e. a screw that includes a head of greater diameter than that of third opening and a threaded shank that projects from said head, said shank projecting longitudinally through said first, second and third centered openings; and f. a nut that removably engages said shank to hold said closure, weight and retainer together as an integral unit wherein said weight is mounted between said closure and said retainer, said weight together with the weight of said agent said container maintaining said container in an inverted free floating position when said assembly is disposed in said water, with a portion of said container projecting above the surface of said water, said assembly floating due to a body of air trapped in the upper interior of said container, and said weight of such magnitude that it maintains said container in an inverted position in said water with the uppermost ones of said passages below the surface of said water to prevent the escape of said trapped body of air after said agent has been depleted by dissolving in water that enters said container through said passages as said assembly floats in a random pattern in said water.
