Abstract

A liquid dispensing device including a sealing component which can take up a liquid release position and a liquid blocking position. The liquid dispensing device also includes a surface for immobilising the sealing component in its blocking position, configured to prevent the sealing component from taking up its liquid release position.

Claims

1. A liquid dispensing device characterised in that it comprises a sealing component which can take up a liquid release position and a liquid blocking position, an outer envelope covering in particular the sealing component, this envelope comprising a liquid release orifice, the sealing component comprising a distal end projecting from the liquid release orifice, the device also comprising a removable cap and means for immobilising the sealing component in its blocking position, configured to prevent the sealing component from taking up its liquid release position, the immobilisation means being supported by the cap, exerting a pressure on the sealing component and being activated when the cap is fitted on the device.

2. The device according to claim 1, comprising venting means allowing air to enter into a reservoir.

3. The device according to claim 2, wherein the cap comprises, in addition to the immobilisation means for the sealing component, means for an airtight sealing of the device, preventing air from passing through the venting means when the cap is fitted on the device.

4. The device according to claim 3, wherein the airtight sealing means comprise an annular rib projecting inside from a wall of the cap and being clamped against a wall for ensuring the airtight sealing.

5. The device according to claim 1, comprising means for pressing on the sealing component, exerting on this component a pressure opposite to the pressure exerted by the immobilisation means.

6. The device according to claim 1, wherein the immobilisation means comprise a surface for pressing on the sealing component.

7. The device according to claim 6, wherein the pressing surface of the immobilisation means is arranged opposite or staggered with respect to the pressing means.

8. The device according to claim 1, wherein the outer envelope comprises an inner opened projection intended to encircle the distal end of the sealing component.

9. The device according to claim 1, wherein the inner opened projection is formed by an annular rib ending by the liquid release orifice.

10. The device according to claim 8, wherein the outer envelope comprises a bearing seat for a return element holding the sealing component in blocking position, the seat being arranged around the inner opened projection.

11. The device according to claim 6, wherein the surface is a projection designed to press on the sealing component.

12. The device according to claim 6, wherein the surface is an annular rib formed on the inner surface of the cap.
