Abstract

An aerosol product diffuser assembly comprises: a diffuser block ( 1 ) comprising an annular casing ( 2 ) inside which a cam actuator ( 3 ) is mounted axially mobile, a control lever ( 10 ) provided with a planar body ( 12 ) making it possible to control the diffusion of the aerosol liquid said cam actuator ( 3 ) comprising: (i) an axially mobile cam follower plate ( 4 ); (ii) an aerosol bottle nozzle housing ( 5 ), arranged on the cam follower plate ( 4 ); (iii) a duct ( 6 a ) connected to the nozzle housing and enabling the liquid to diffuse to a discharge point of the aerosol liquid, the control lever ( 10 ) being pivotably mounted on the annular casing ( 2 ), and the cam actuator ( 3 ) being able to be pushed axially towards the aerosol bottle by at least one pivoting cam ( 15 ).

First claim

The invention claimed is:

1. An aerosol product diffuser assembly for a pressurized bottle comprising:
a diffuser block comprising an annular casing inside which a cam actuator is mounted axially mobile between a storage position of the aerosol and a diffusion position of the aerosol; and
a control lever provided with a planar body making it possible to control the diffusion of the aerosol liquid,
wherein the cam actuator comprises:
(i) a cam follower plate, axially mobile and guided by guide studs fixed to the annular casing and engaging with corresponding notches in the cam follower plate;
(ii) an aerosol bottle nozzle housing, arranged on the cam follower plate and suitable for receiving a nozzle of an aerosol bottle;
(iii) a duct and a diffuser tip, connected to the nozzle housing and enabling the liquid to diffuse to a discharge point of the aerosol liquid,

wherein the control lever is pivotably mounted on the annular casing,
wherein the cam actuator is able to be pushed axially toward the aerosol bottle by at least one pivoting cam, mounted on the planar body of the control lever,
wherein the cam actuator is pushed axially away from the aerosol bottle by at least one elastic fastening tab elastically connecting the cam actuator to the annular casing, and
wherein the cam actuator is formed integrally with the annular casing, thus forming a one-piece diffuser block.

2. The aerosol product diffuser assembly according to claim 1 , wherein the annular casing comprises substantially facing openings that form a pivot axis P-P and the control lever comprises two pivots on opposite sides that form a corresponding pivot axis P′-P′ and are capable of engaging with the openings in the annular casing to form a pivoting mounting of the control lever in the annular casing, with the axes P-P and P′-P′ being superposed.

3. The aerosol product diffuser assembly according to claim 1 , wherein the control lever comprises two cams spaced apart from each other, between which the nozzle housing can be inserted.

4. The aerosol product diffuser assembly according to claim 3 , wherein the two cams are suitable for exerting an axial force F to the bottle by contact on the cam follower plate on each side of the nozzle housing.

5. The aerosol product diffuser assembly according to claim 1 , wherein the control lever comprises a breakable securing catch, mounted substantially extending from the planar body.

6. The aerosol product diffuser assembly according to claim 1 , wherein the annular casing comprises a lateral opening provided to enable the diffuser tip to project radially beyond the casing.

7. The aerosol product diffuser assembly according to claim 1 , wherein at least one cam comprises a locking nose that makes it possible to place the control lever in one or the other of two bistable positions, a closed position corresponding to the storage position of the aerosol and an open position corresponding to the diffusion position of the aerosol.

8. An aerosol can using an aerosol product diffuser assembly according to claim 1 .
