Abstract

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.

First claim

The invention claimed is:

1. A refillable fluid dispenser comprising:
a fluid reservoir defining a neck and a bottom wall provided with an opening that is arranged remote from the neck;
a filling valve that is mounted in the opening of the bottom wall, the filling valve including a movable member and a valve seat for the movable member;
a dispenser member, such as a pump, mounted on the neck of the reservoir for taking the fluid, the dispenser member comprising a body and an actuator rod that is axially movable down and up, the dispenser member incorporating a vent system making it possible to establish selectively a vent passage between the reservoir and the outside through the dispenser member the actuator rod being movable axially between a rest position and a depressed position, the vent passage being closed in the rest position and open in the depressed position; and
a pusher that is mounted on the actuator rod of the dispenser member;
the fluid dispenser being characterized in that it further comprises abutment means for holding the pusher when pressure exerted on the filling valve is transmitted to the dispenser member in such a manner as to move the body relative to its actuator rod so as to bring it into its depressed position in order to open the vent passage, the abutment means being formed by a manual grip member in which the reservoir is slidably mounted, the abutment means comprising an inwardly-directed rim against which the pusher comes to bear, in particular when pressure is exerted on the filling valve.

2. A dispenser according to claim 1 , wherein the manual grip member is in the form of a casing that can be held with one hand, the pusher forming a bearing flange that is engaged below the inwardly-directed rim.

3. A dispenser according to claim 1 , wherein the reservoir is slidably mounted in the manual grip member to slide over a limited axial stroke that defines a high position and a low position of the reservoir in the manual grip member, the actuator rod being in its rest position when the reservoir is in its low position, and in its depressed position when the reservoir is in its high position.

4. A dispenser according to claim 3 , wherein the manual grip member includes an inside annular groove, and the reservoir includes at least one projecting outside lug that is received in the inside annular groove in such a manner as to be capable of being moved therein over said limited axial stroke.

5. A dispenser according to claim 3 , further comprising a cap for covering and protecting the filling valve, the cap being mounted in removable manner on the reservoir, coming into engagement with the manual grip member in such a manner as to push the reservoir into its low position.

6. A dispenser according to claim 5 , wherein the cap is screw-fastened on the reservoir and includes a top annular edge that comes into axial thrust contact against the manual grip member.

7. A dispenser according to claim 1 , wherein the vent system comprises a vent hole that passes through the body, and a valve gasket that is arranged around the actuator rod and that is advantageously secured to a ferrule that is engaged in stationary manner in the body, the valve gasket co-operating with the actuator rod to create a seal when the actuator rod is in its rest position, and opening the vent passage when the actuator rod is in its depressed position.

8. A dispenser according to claim 1 , wherein the vent passage of the dispenser member opens out into a space that communicates with the outside at the abutment means.

9. A dispenser according to claim 1 , wherein the movable member of the filling valve comprises a flexible diaphragm that selectively bears in leaktight manner against the valve seat, forming an upstream filling channel that extends from a reception housing for receiving the nozzle of a source bottle.
