Abstract
A fluid dispenser housing including a lever, a biasing mechanism, and a pump engagement member. When the lever is at a rest position and the pump engagement member is at a home position, movement of the lever from the rest position to an activated position causes the lever to engage with the pump engagement member, which moves the pump engagement member from the home position to a depressed position. When the lever returns to the rest position from the activated position under the bias of the biasing mechanism, the lever disengages from the pump engagement member.
Claims18
A fluid dispenser housing comprising:
- a lever that is moveable between a rest position and an activated position;
- a biasing mechanism that biases the lever towards the rest position;
- and
- a pump engagement member that is moveable between a home position and a depressed position;
- wherein the lever and the pump engagement member are configured to have a one-way engagement connection;
- wherein the one-way engagement connection is configured so that:
- when the lever is at the rest position and the pump engagement member is at the home position, movement of the lever from the rest position to the activated position applies an activation force to the pump engagement member via the one-way engagement connection, which moves the pump engagement member from the home position to the depressed position;
- and
- when the lever returns from the activated position to the rest position under the bias of the biasing mechanism, no force that would return the pump engagement member from the depressed position to the home position is applied to the pump engagement member via the one-way engagement connection;
- wherein the fluid dispenser housing is configured to receive a fluid dispenser;
- wherein, when the fluid dispenser is absent from the fluid dispenser housing, the lever is at the rest position, the pump engagement member is at the home position, and the lever moves from the rest position to the activated position, the lever engages with the pump engagement member, which moves the pump engagement member from the home position to the depressed position;
- and
- wherein, when the fluid dispenser is absent from the fluid dispenser housing, and the lever returns to the rest position from the activated position under the bias of the biasing mechanism, the lever disengages from the pump engagement member.
