## Abstract

A refillable fluid dispenser comprising: a fluid reservoir (1) defining a neck (11) and a bottom wall (13); a filling valve (2); a dispenser member (4), such as a pump; a pusher (6) that is mounted on the dispenser member (4); and a vent channel (12) that extends along the fluid reservoir (1) and that is made integrally with the fluid reservoir (1); the dispenser being characterized in that it includes a stationary element (20) that is mounted on the bottom wall (13) of the fluid reservoir (1), the stationary element (20) forming a vent passage (221, 222) that connects the outlet of the vent channel (12) to the outside.

## Claims

### Claim 1

A refillable fluid dispenser comprising:
a fluid reservoir defining a neck and a bottom wall provided with an opening;
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, that is mounted on the reservoir so as to take the fluid, the dispenser member including a body and an actuator rod that is axially movable down and up;
a pusher that is mounted on the actuator rod of the dispenser member; and
a vent channel that extends along the fluid reservoir so as to put the fluid reservoir into communication with the outside, the vent channel defining an inlet in the proximity of the neck, and an outlet that opens out at the bottom wall, the vent channel being made integrally with the fluid reservoir;
the dispenser being characterized in that it includes a stationary element that is mounted on the bottom wall of the fluid reservoir, the stationary element forming a vent passage that connects the outlet of the vent channel to the outside.

### Claim 2 (depends on 1)

A dispenser according to claim 1, wherein the outlet of the vent channel presents a flow section that is larger than the flow section of the inlet.

### Claim 3 (depends on 1)

A dispenser according to claim 1, wherein the vent channel presents a configuration that flares towards its outlet.

### Claim 4 (depends on 1)

A dispenser according to claim 1, wherein the vent passage presents a flow section that is smaller than the flow section of the outlet.

### Claim 5 (depends on 1)

A dispenser according to claim 1, wherein the vent passage comprises a vent hole that is arranged at the outlet.

### Claim 6 (depends on 1)

A dispenser according to claim 1, wherein the vent passage comprises an annular duct and a vent hole, the annular duct connecting the outlet to the vent hole.

### Claim 7 (depends on 1)

A dispenser according to claim 1, wherein the stationary element includes a disk that is provided with an annular groove in which there is formed a vent hole that passes through the thickness of the disk.

### Claim 8 (depends on 1)

A dispenser according to claim 1, wherein the stationary element also forms the valve seat of the filling valve.

### Claim 9 (depends on 1)

A dispenser according to claim 1, wherein the movable member of the filling valve comprises a slotted flexible diaphragm that bears in leaktight manner on the valve seat, in the rest position.

### Claim 10 (depends on 9)

A dispenser according to claim 9, wherein the slotted flexible diaphragm is formed by a flexible part that further includes an annular anchor band in which the slotted flexible diaphragm extends, the annular anchor band being jammed between the bottom wall and the stationary element.

### Claim 11 (depends on 1)

A dispenser according to claim 1, further comprising a removable cap that covers the stationary element in airtight manner.

### Claim 12 (depends on 2)

The dispenser according to claim 2, wherein the vent channel presents a configuration that flares towards its outlet.
