Patent ID: 8261943

Claim:
A refill assembly comprising: a bottle defining an internal reservoir and an opening which communicates with the reservoir; and a refill cartridge operatively coupled with the bottle, the refill cartridge including: a cartridge body defining a cartridge reservoir having a concentrated chemical agent stored therein, the cartridge body including a tubular projection defining an opening which fluidly communicates with the cartridge reservoir; a cap connected to the cartridge body and including a tubular boss defining a flow passage which fluidly communicates with the cartridge reservoir; and a release mechanism frictionally engaged to the boss and the projection, the cartridge reservoir being collectively defined by the cartridge body, the cap and the release mechanism; wherein, the release mechanism at least partially protrudes from the cap, the application of pressure to that portion of the release mechanism, protruding from the cap facilitating the movement thereof from a sealing position to a dispensing position to facilitate the formation of a fluid flow path between the projection and a portion of the release mechanism to facilitate flow of the chemical agent from the cartridge reservoir into the reservoir of the bottle.
