Abstract

A floating dispenser having an external float or an internal float for supporting a cartridge or cartridges for floatingly delivering a dispersant or dispersants to a body of water with the floating dispenser having cartridges rotationally positionable with respect to one another to control the rate of dispensing while the dispenser floats in an upright condition with the floating dispenser changing its flotation orientation in response to consumption of the dispersant or dispersants in the a cartridge to thereby provide a visual alert to replace a spent cartridge with a fresh cartridge. In addition, the inventions described herein permit changing the dispensing nature of the system from a multiple dispensing system to a single dispensing system without changing the floating characteristics of the floating dispensers through replacement of a dispersant in one of the cartridges with an inert or ballast material that has no effect on the water characteristics.

First claim

We claim:

1. A floating dispenser comprising; a flotation member; a first dispensing cartridge; and a second dispensing cartridge rotationally engaged with the first dispensing cartridge with a rotational position of the first dispensing cartridge with respect to the second dispensing cartridge determining a dispersant rate of at least one of the cartridges when the cartridges are floating in a body of water wherein the flotation member and the first dispensing cartridge comprise an insertable pouch containing a material having a specific gravity greater than 1 located in a top position in the floating dispenser and the second dispensing cartridge is located in a bottom position in the floating dispenser, which is below a water line when the floating dispenser is in an unspent state and the second dispensing cartridge is located in a top position above the water line when a dispensing material therein is spent.

2. The floating dispenser of claim 1 wherein the first dispensing cartridge contains alum and minerals and the flotation member is located internal or external to either the first dispensing cartridge or the second dispensing cartridge.

3. The floating dispenser of claim 1 wherein the first dispensing cartridge contains a ballast, which may or may not contain a water affecting material and the second dispensing cartridge contains a dispensable material with the dispensable material comprising either dichlor or trichlor or both.

4. The flotation dispenser of claim 1 wherein the first dispensing cartridge is secured to a first end of the flotation member and the second dispensing cartridge is secured to an opposite end of the flotation member.

5. A floating dispenser comprising;
a flotation member;
a first dispensing cartridge; and
a second dispensing cartridge rotationally engaged with the first dispensing cartridge with a rotational position of the first dispensing cartridge with respect to the second dispensing cartridge determining a dispersant rate of at least one of the cartridges when the cartridges are floating in a body of water wherein the first dispensing cartridge contains a ballast which may be an active or an inactive ballast that weighs less than the dispensable material in the second dispensing cartridge so that the floating dispenser floats with the second dispensing cartridge below a water line and inverts when the dispensable material in the second dispensing cartridge is consumed.
