A refill cartridge disposable within a spray bottle during usage thereof. The refill cartridge includes a cartridge body defining a cartridge reservoir. The cartridge body includes first and second openings, the second opening being defined by a projection of the cartridge body. A cap is connected to the cartridge body to substantially cover the first opening. The cap includes a cap base having a primary opening. A cap boss is connected to and extends from the cap base and defines a passage concentrically aligned with the primary opening. The refill cartridge additionally includes a plug having a plug body including a plug neck and a flared portion, with the plug neck defining a distal end. The plug is engageable with the cap and the cartridge body and is moveable relative to the cap and cartridge body between a sealing position and a dispensing position.

1. A refill cartridge for use with a spray bottle assembly comprising a bottle which defines an internal reservoir and an opening which communicates with the reservoir, and a pumping mechanism which is attached to the bottle and includes a feed tube which extends into the internal reservoir, the refill cartridge comprising: a cartridge body configured to cooperatively engageable the bottle in a manner substantially covering the opening thereof, the cartridge body defining a cartridge reservoir adapted to have a concentrated chemical agent stored therein, the cartridge body including an elongate channel disposed therein and configured to accommodate the passage of the feed tube into the internal reservoir;wherein the cartridge body is generally cylindrical and includes a side wall, a bottom wall connected to the side wall, and a top wall connected to the side wall, the channel being disposed within the side wall and extending between the top and bottom walls. 2. The refill cartridge of claim 1 further comprising a cap connected to the top wall and including a peripheral portion which protrudes radially from the side wall and is sized and configured to be placeable upon a portion of the bottle which defines the opening thereof. 3. The refill cartridge of claim 2 wherein the cap includes a slot which communicates with the channel. 4. The refill cartridge of claim 1 wherein the top wall includes a peripheral portion which protrudes radially from the side wall and is sized and configured to be placeable upon a portion of the bottle which defines the opening thereof. 5. The refill cartridge of claim 4 wherein the top wall includes a slot which communicates with the channel. 6. The refill cartridge of claim 1 wherein the channel has a generally U-shaped cross-sectional configuration. 7. A refill cartridge for use with a containment vessel defining an internal reservoir and an opening which communicates with the reservoir, the refill cartridge comprising: a cartridge body having a flange portion which is sized and configured to be placeable upon a portion of the containment vessel which defines the opening thereof, the cartridge body defining a cartridge reservoir adapted to have a concentrated chemical agent stored therein, the cartridge body including a tubular projection defining an opening which fluidly communicates with the cartridge reservoir;a plug cooperatively engaged to the cartridge body and selectively movable from a sealing position to a dispensing position relative thereto, the movement of the plug from the sealing position to the dispensing position facilitating the flow of the chemical agent from the cartridge reservoir; anda cap connected to the cartridge body and including a tubular boss including a tapered inner surface defining a flow passage which fluidly communicates with the cartridge reservoir, the cartridge reservoir being collectively defined by the cartridge body, the plug and the cap;wherein the plug protrudes from the cap and is tubular and includes a neck which is frictionally engaged to and creates a fluid tight seal with the boss when the plug is in both the sealing and dispensing positions, and a flared portion which is frictionally engaged to and creates a fluid tight seal with the projection when the plug is in the sealing position, but is disposed in spaced relation to the projection upon the movement of the plug to the dispensing position such that a fluid flow path is defined between the plug and the cartridge body. 8.
