Abstract
Official abstract text for this publication.
A multi-stage floatation dispenser for carrying a ballast, which may be a non-water consumable dispersant and at least one water consumable dispersant wherein the weight of the water consumable dispersant decreases as the water consumable dispersant is consumed with the weight of water consumable dispersant and the non-water consumable coordinated with the flotation capacity of a flotation dispenser to provide for either a two stage or a three stage dispensing mode.
First claim
Opening claim text (preview).
I claim: 1. A method of delivering two or more dispersants to a body of water through a flotation dispenser comprising: placing a first non-water consumable dispersant in the flotation dispenser; placing a water consumable dispersant in a cartridge with the cartridge axially below the non-water consumable dispersant in the flotation dispenser with the water consumable dispersant having a weight greater than a weight of the non-water consumable dispersant; and placing the flotation dispenser with the water consumable dispersant and the non-water consumable dispersant in the body of water wherein the weight of the water consumable dispersant in a consumed state is insufficient to maintain the flotation dispenser in a submerged condition. 2. The method of claim 1 including a step of placing the water consumable dispersant in a replaceable cartridge that is removable from the flotation dispenser to enable replacement of the replaceable cartridge in the flotation dispenser when the water consumable dispersant therein has been consumed without having to replace the non-water consumable dispersant in the floatation dispenser. 3. The method of claim 2 including a step of spacing the replaceable cartridge from a wall of the flotation dispenser to provide a water passage therebetween for directing water to a water port of the replaceable cartridge from an underside of the floatation dispenser.
