Metal crimping cap for a fluid dispensing device

1. A metal crimping cap ( 10 ) for a fluid dispenser device, said cap ( 10 ) acting to fix a dispensing member ( 20 ) such as a pump or a valve to the neck ( 31 ) of a reservoir ( 30 ) containing fluid to be dispensed, said cap ( 10 ) having a fixing portion ( 11 ) for receiving said dispensing member ( 20 ) securely, and a crimping portion ( 12 ) which serves to be crimped to the neck ( 31 ) of the reservoir ( 30 ), said crimping portion ( 12 ) being provided with a covering element ( 15 ) made of a plastics material and extending over at least a fraction of the inside surface of said crimping portion ( 12 ), and over at least a fraction of the outside surface thereof, so that no metal particles are generated before, during and/or after crimping, said cap being characterized in that, on the outside surface of said crimping portion ( 12 ) of the cap ( 10 ), said covering element ( 15 ) is provided with retaining means ( 18 ) adapted to co-operate with a pusher to retain said pusher by preventing it from being removed from said dispensing member ( 20 ).

2. A cap according to claim 1 , in which said covering element ( 15 ) surrounds said crimping portion ( 12 ) completely.

3. A cap according to claim 1 , in which said covering element ( 15 ) is extended over the inside surface of the cap ( 1 ) by a radial flange ( 16 ) that forms a sealing gasket for the neck ( 31 ) of the reservoir.

4. A cap according to claim 3 , in which said radial flange ( 16 ) that forms the sealing gasket is extended by an extension or bushing ( 17 ) that is preferably approximately frustoconical, and that co-operates in leaktight manner with said dispensing member ( 20 ).

5. A cap according to claim 1 , in which said retaining means ( 18 ) are formed by a peripheral rib ( 18 ) that is adapted to co-operate, e.g. by snap-fastening, with a skirt on a pusher.

6. A cap according to claim 1 , in which said covering element ( 15 ) is provided with identification means making it possible to identify parameters characteristic of the fluid dispenser device and/or of the fluid.

7. A cap according to claim 6 , in which said identification means are visual, such as color, and/or tactile.

8. A fluid dispenser device including a dispensing member ( 20 ) such as a pump or a valve fitted to a reservoir ( 30 ) containing fluid, said fluid dispenser being characterized in that it includes a crimping cap ( 10 ) according to claim 1 , for fixing said dispensing member ( 20 ) to the neck ( 31 ) of the reservoir ( 30 ).
