摘要:
A refillable fluid dispenser having a fluid reservoir (1) with a bottom wall (12) provided with an opening (13); a filling valve (2) mounted in the opening and that includes a movable member (26) and a valve seat (21); a dispenser member (4) having an actuator rod (44) and a vent system, the actuator rod (44) movable axially between a rest position and a depressed position and the vent system closed in the rest position and open in the depressed position; and a pusher (6) mounted on the actuator rod (44). The fluid dispenser includes an abutment mechanism (76) for holding the pusher (6) when pressure exerted on the filling valve (2) is transmitted to the dispenser member (4) so as to move the dispenser member body (41) relative to its actuator rod (44) to bring it into its depressed position in order to open the vent passage.

Exemplary embodiments of dispensers and refill units are disclosed herein. An exemplary refill unit for a soap, sanitizer or lotion includes a non-collapsing container. The non-collapsing container includes a neck. An annular projection is located at least partially on the neck. A one-way valve is located proximate the annular projection. The one-way valve allows air to flow into the non-collapsing container once the vacuum pressure in the container reaches the cracking pressure of the one-way valve and the one-way valve prevents liquid from flowing out of the annular projection. In addition, a pump for pumping the contents of the container out of the container is also included.
