Abstract

A liquid-dispensing device including a cap for protecting a liquid-dispensing opening, the protective cap being provided with a pad for absorbing residual liquid, made of an absorbent material, the absorbent pad being fastened to a support made of a more resistant material than the absorbent pad, the support being furthermore fastened in the protective cap.

First claim

The invention claimed is:

1. A liquid-dispensing device, comprising:
an end piece with a liquid-dispensing opening removably attachable to a neck of a tank;
a removable protective cap for covering the liquid-dispensing opening, the protective cap comprising an outer casing and an inner casing connected to one another and removable together to uncover the liquid-dispensing opening, the protective cap being provided with a residual liquid absorption pad, made of an absorbent material,
the absorption pad being fixed onto a support made of a stronger material than the absorption pad, the support being distinct from, such that the support is not integrally formed with, the protective cap and also fixed in the inner casing of the protective cap.

2. The device according to claim 1 , in which the support is made of a plastic material.

3. The device according to claim 1 , in which the support has an annular form.

4. The device according to claim 1 , in which the support extends over the entire height of the absorption pad.

5. The device according to claim 1 , in which the absorption pad is overmolded on the support.

6. The device according to claim 1 , in which the absorption pad is made of a porous material.

7. The device according to claim 1 , in which the absorption pad is made of a material comprising EVA (ethylene vinyl acetate).

8. The device according to claim 1 , in which the absorption pad comprises at least two stacked pad layers.

9. The device according to claim 1 , in which the absorption pad is kept immobile between two axial abutments of the support cooperating with the absorption pad.

10. The device according to claim 9 , in which the support comprises two parts fitted into one another, each part defining an axial abutment.

11. The device according to claim 1 , comprising a residual liquid expulsion form situated in the immediate vicinity of and facing the dispensing opening and borne by the protective cap or the support, when the protective cap is mounted on the device.

12. The device according to claim 1 , that can take, when the protective cap is mounted on the device, a configuration of hermetic closure of the device, before its first use, in which a residual liquid evaporation path is closed between the absorption pad and the outside of the device, and a configuration of ventilation of the device, in which the residual evaporation path is open between the absorption pad and the outside.

13. The device according to claim 12 , wherein the outer casing the inner casing are mounted mobile relative to one another between a first configuration, corresponding to the configuration of hermetic closure of the device, and the configuration of ventilation of the device.

14. The device according to claim 12 , in which the protective cap comprises air passage orifices and a seal closing the residual liquid evaporation path before the first use.

15. A method for assembling a device according to claim 1 , during which the absorption pad and the support are first of all assembled, then the assembly is added into the protective cap.

16. The method for assembling a device according to claim 15 , further comprising a step of blowing of compressed air over the assembly of the absorption pad and the support, before they are added into the protective cap.

17. The device according to claim 2 , in which the support is made of polyethylene.

18. The device according to claim 1 , wherein the absorption pad is least axially supported in the inner casing of the protective cap by the support.

19. The device according to claim 1 , wherein the absorption pad is retained in the protective cap only by interaction between support and an interior surface of the inner casing of the protective cap.
