Abstract:
1. A dispenser for dispensing fluid comprising: a housing, a fluid containing reservoir having an outlet, the housing supporting the reservoir in a dispensing position, the reservoir being insertable into said housing to assume said dispensing position and removable therefrom for replacement, a valving mechanism disposed across the outlet for dispensing fluid from the reservoir, the valving mechanism comprising a reciprocally movable element for reciprocal movement along an axis relative to the housing when the reservoir is in the dispensing position to dispense fluid, the housing including an actuator mechanism for actuating the reciprocally movable element, the actuator mechanism movable relative the housing between a first position and a second position, the actuator mechanism including a catch member, the movable element including an engagement mechanism to engage the catch member and releasably couple the movable element to the actuator mechanism in a coupled orientation in which movement of the actuator mechanism between the first position and the second position results in axial reciprocal movement of the movable element, the engagement mechanism comprising a resilient member extending radially outwardly from the movable element in an unbiased inherent configuration, the resilient member being resiliently deflectable radially from the inherent configuration to deflected configurations of different radial extents than the inherent configuration and biased to return to the inherent configuration when deflected from the inherent configuration, wherein from the coupled orientation on moving the movable element radially relative the catch member engagement between the catch member and the resilient member on the movable element deflects the resilient member radially from the inherent configuration to one of the deflected configurations permitting the resilient member and catch member to move radially from the coupled orientation to a radial uncoupled orientation in which the reservoir may be removed from the housing, in the coupled orientation the resilient member while in the inherent configuration engaging with the catch member to prevent moving the movable element radially relative the catch member from the coupled orientation to the radial uncoupled orientation.
