Abstract

A device for dispensing a fluid product having a container ( 10 ), a dispensing member ( 20 ), a dispensing head ( 30 ) with an outlet ( 31 ), an actuating member ( 60 ) slidably mounted in the dispensing head, and a lateral actuating system cooperating with the actuating member. The actuating member has a cylindrical body ( 65 ) and a flexible tab ( 61 ) having a radial projection ( 62 ), the flexible tab extending axially into the cylindrical body ( 65 ) and radially deformable between an undeformed position, in which the projection ( 62 ) projects radially out of the cylindrical body, and a deformed position, in which the projection does not. The lateral actuating system has two side levers ( 35, 36 ) diametrically opposed, deformable and/or movable laterally, a flexible spacer ( 37 ) connecting the two side levers, the flexible spacer cooperating with the projection ( 62 ) and axially deformed during actuation to axially move the actuating member relative to the dispensing head.

First claim

The invention claimed is:

1. A device for dispensing a fluid product comprising a container containing at least one dose of fluid product, a dispensing member, a dispensing head provided with a dispensing outlet, said container being movable relative to said dispensing head to move said dispensing member in said container and thus dispense fluid product through said dispensing outlet, an actuating member which is slidably mounted in said dispensing head and cooperates with said container, and a lateral actuating system which cooperates with said actuating member, characterized in that:
said actuating member comprises a cylindrical body and at least one flexible tab provided with at least one radial projection, each flexible tab axially extending in said cylindrical body and being radially deformable between an undeformed position, in which said at least one radial projection radially projects out of said cylindrical body, and a deformed position, in which said at least one radial projection does not radially project out of said cylindrical body,
said lateral actuating system comprises two side levers which are diametrically opposed, deformable and/or laterally movable relative to said dispensing head, at least one flexible spacer connecting said two side levers, said at least one flexible spacer cooperating with a radial projection of said actuating member and being axially deformed upon actuation to move said actuating member axially with respect to said dispensing head.

2. The device according to claim 1 , wherein said actuating member comprises two radially flexible tabs which are diametrically opposed.

3. The device according to claim 1 , wherein said container contains two doses of fluid product, dispensed during two successive actuations of the device.

4. The device according to claim 3 , wherein each radially flexible tab of said actuating member comprises two axially offset radial projections for dispensing two successive doses.

5. The device according to claim 1 , wherein said side levers are each formed by a flexible elongated blade, one end of which, proximal to the dispensing outlet, is attached to the said dispensing head, and the opposite end of which, distal from the dispensing outlet, is radially spaced from the said dispensing head, said at least one flexible spacer being dome shaped and connecting said two flexible elongated blades in the vicinity of the said distal ends.

6. The device according to claim 5 , wherein said side levers are deformable and/or laterally movable, between a rest position in which they are distant from said dispensing head, and an actuating position in which they are close to said dispensing head, the movement of said side levers towards the actuating position deforming and/or compressing said at least one flexible spacer by increasing its curvature, and thus axially moving the apex of the curvature towards the dispensing outlet.

7. The device according to claim 5 , wherein stops are provided on the dispensing head to define the actuating position of said side levers.

8. The device according to claim 1 , wherein before the first actuation, all radial projections are axially arranged behind the apex of the curvature of said at least one flexible spacer to form an actuation safety feature which prevents accidental actuation of the device.

9. The device according to claim 8 , wherein to activate the device, the activating member is axially moved relative to said dispensing head until said at least one flexible spacer is positioned below the first radial projection of said activating member.

10. The device according to claim 1 , comprising an indicator for indicating to the user the dispensing of each dose.

11. The device according to claim 10 , wherein said indicator comprises viewing windows formed in said dispensing head.

12. The device according to claim 1 , wherein said actuating member comprises radial notches cooperating with radial projections of said dispensing head, to maintain the actuating member in position in said dispensing head before and after actuation.

13. The device according to claim 1 , wherein the dispensing member is a piston that is slidably mounted in the container to dispense fluid product.
