Abstract

A diffuser (1) for dispensing a product has a base (10); a push button (20) with a channel (23) opening at one end on an outlet (24) for the product; a cap (30) connected to the base by a hinge (17, 17′) so as to be movable between a closed position folded down on the base while isolating the push button (20) and the outlet opening (24) from the outside, and an upright open position, providing access to the push button and freeing the outlet; tamper-evident means (40, 18) made up of a strip (40) and a shoulder (18), one being fastened to the cap (30) and the other to the base (10), so that, with the cap in the closed position, the shoulder is snapped behind an abutment (43) formed in the strip without being able to free itself otherwise than by tearing off the strip.

Claims

1. Diffuser for dispensing a product contained in a container, said diffuser being equipped with

a base to fasten the diffuser to a container;

a push button equipped with a channel opening at one end on means for cooperating with a dispensing device of a container and at the other end on an opening outlet through which the product contained in a container can exit;

a cap connected to the base by a hinge so as to be movable between a closed position in which the cap is folded down on the base while isolating the push button and the outlet opening from the outside, and an open position in which the cap is upright, providing access to the push button and freeing the outlet opening,

tamper-evident means that must be partially torn off upon the first use to make it possible to move the cap from the closed position to the open position, the tamper-evident means being made up of both a strip and a shoulder, one being fastened to the cap and the other to the base, the strip being fastened to the cap or to the base by connecting means which can easily be torn by hand, and the shoulder being placed on the base or the cap so that when the cap is placed in the closed position, the shoulder is snapped behind an abutment formed in the strip without being able to free itself except by tearing off the strip.

2. The diffuser according to claim 1, wherein the strip is fastened to the cap or to the base by a plurality of bridges extending from a face of an edge of the strip to the cap or to the base, wherein the face of the edge of the strip between two particular bridges forms the abutment behind which the shoulder is snapped.

3. The diffuser according to claim 1, wherein the strip is fastened to the cap and the shoulder is formed in the base.

4. The diffuser according to claim 3, wherein the strip has an L-shape constituted by a vertical branch and a transverse branch, and in that the cap is equipped with a recess, the top of the vertical branch being connected by first bridges to the top, considering the cap in the closed position, of the recess, and the free end of the transverse branch being connected to the lower portion, considering the cap in the closed position, of the cap.

5. The diffuser according to claim 1, wherein the shoulder is wedge-shaped with an inclined surface and a radial surface, the radial surface cooperating with the strip to block the cap in the closed position.

6. The diffuser according to claim 1, wherein the push button is connected to the base by a tab so as to be movable toward a side of the base opposite the cap when the cap is in the closed position.

7. The diffuser according to claim 1, wherein the outlet opening is provided with a nozzle for generating a spray.

8. The diffuser according to claim 2, wherein the strip is fastened to the cap and the shoulder is formed in the base.

9. The diffuser according to claim 8, wherein the strip has an L-shape constituted by a vertical branch and a transverse branch, and in that the cap is equipped with a recess, the top of the vertical branch being connected by first bridges to the top, considering the cap in the closed position, of the recess, and the free end of the transverse branch being connected to the lower portion, considering the cap in the closed position, of the cap.

10. The diffuser according to claim 2, wherein the shoulder is wedge-shaped with an inclined surface and a radial surface, the radial surface cooperating with the strip to block the cap in the closed position.

11. The diffuser according to claim 3, wherein the shoulder is wedge-shaped with an inclined surface and a radial surface, the radial surface cooperating with the strip to block the cap in the closed position.

12. The diffuser according to claim 4, wherein the shoulder is wedge-shaped with an inclined surface and a radial surface, the radial surface cooperating with the strip to block the cap in the closed position.

13. The diffuser according to claim 8, wherein the shoulder is wedge-shaped with an inclined surface and a radial surface, the radial surface cooperating with the strip to block the cap in the closed position.

14. The diffuser according to claim 9, wherein the shoulder is wedge-shaped with an inclined surface and a radial surface, the radial surface cooperating with the strip to block the cap in the closed position.

15. The diffuser according to claim 2, wherein the push button is connected to the base by a tab so as to be movable toward a side of the base opposite the cap when the cap is in the closed position.

16. The diffuser according to claim 3, wherein the push button is connected to the base by a tab so as to be movable toward a side of the base opposite the cap when the cap is in the closed position.

17. The diffuser according to claim 4, wherein the push button is connected to the base by a tab so as to be movable toward a side of the base opposite the cap when the cap is in the closed position.

18. The diffuser according to claim 5, wherein the push button is connected to the base by a tab so as to be movable toward a side of the base opposite the cap when the cap is in the closed position.

19. The diffuser according to claim 2, wherein the outlet opening is provided with a nozzle for generating a spray.

20. The diffuser according to claim 3, wherein the outlet opening is provided with a nozzle for generating a spray.
