Abstract

A liquid dispenser device including a valve with a valve member-forming portion for blocking and passing liquid out from the device, and a fastener edge for permanently fastening the valve relative to a container, the fastener edge including a tubular fastener wall sandwiched between an inner tubular wall and an outer tubular wall.

Claims

1. A liquid dispenser device including a valve comprising:

a valvemember-forming portion for blocking and passing liquid out from the device; and

a fastener edge for permanently fastening the valve relative to a container, the fastener edge comprising a tubular fastener wall sandwiched between an inner tubular wall and an outer tubular wall, the inner tubular wall being carried by a housing mounted on the container, and the housing covering the valve, at least in part.

2. The device according to claim 1, wherein the outer tubular wall is carried by a support mounted on the container.

3. The device according to claim 1, wherein the valve seat further includes a cylindrical central portion having its distal end forming a bearing surface for the valvemember-forming portion of the valve when in the liquid-blocking configuration.

4. The device according to claim 1, wherein the valve includes a screen delimited at its periphery by the fastener wall and including a central cylindrical portion projecting from the screen and having its end constituting the portion forming the valve member of the valve.

5. The device according to claim 1, wherein the housing includes a groove defined by the inner tubular wall, a bottom wall, and an outer shell, this groove sandwiching the fastener wall of the valve together with the outer tubular wall.

6. The device according to claim 1, including snap-fastener means for snap-fastening a housing carrying the inner tubular wall and a support carrying the outer tubular wall, snap-fastening taking place in the axial direction.

7. The device according to claim 1, wherein the snap-fastener means are configured in such a manner that snap-fastening also corresponds to permanently fastening the valve by pinching between the inner tubular wall and the outer tubular wall.

8. The device according to claim 1, wherein the valvemember-forming portion of the valve and the fastener edge of the valve are made of elastomer material.

9. A method of assembling a device according to claim 1, the method comprising the following steps:

installing the valve on a support by inserting the fastener wall of the valve inside the outer tubular wall;

installing a housing over the valve by inserting the inner tubular wall inside the fastener wall of the valve; and

snap-fastening the housing on the support.

10. The device according to claim 2, wherein the support includes a valve seat having substantially the shape of a disk that is delimited by the outer tubular wall.

11. The device according to claim 8, wherein the valve includes a rigid portion.
