A PRESSURISED REFILL CANISTER WITH AN OUTLET VALVE

摘要

A pressurised refill canister (5) containing a reservoir (31) of composition including a propellant, and a non-metered refill outlet valve (20) comprising a stem (6) displaceable from a first position to a dispensing position against the action of a resilient member. The stem (6) comprises a blind bore open at an outlet end and closed at the opposite end and a lateral bore (27) in the side wall of the stem (6) leading to the blind bore. The refill outlet valve further comprises an annular seal (22) which surrounds the stem (6) whereby, in the first position, the lateral bore (27) is not in communication with the inside of the canister, and in the dispensing position, the lateral bore (27) is arranged to move inside the canister with respect to the seal (22) to open a flow path from the inside of the canister via the lateral bore (27) and along the blind bore to the outlet end.
