Patent ID: 8430137

Claim:
A refill cap comprising: a body including: a cylindrical wall; an end wall extending from the cylindrical wall, the end wall and the cylindrical wall defining an internal reservoir; and a first and a second opening which each communicate with the internal reservoir; a tubular projection extending from the end wall and defining the second opening which fluidly communicates with the internal reservoir; a plug including separate first and second plug portions which are cooperatively engaged to each other, the plug being selectively moveable relative to the body between a sealing position and a dispensing position; a retention bracket extending from the end wall into the internal reservoir; and a retention plate coupled to the second plug portion; the pine being configured such that the second plug portion is frictionally engaged to the tubular projection of the body to effectively block the second when the plug is in the sealing position, the application of pressure on the plug facilitating movement from the sealing position to the dispensing position, with the movement of the plug to the dispensing position facilitating the formation of a fluid flow path between the tubular projection and the second plug portion; the retention plate being spaced from the retention bracket when the plug is in the sealing position and the retention plate being engaged with the retention bracket when the plug is moved to the dispensing position.
