Patent ID: 8002152

Claim:
A fluid dispenser device comprising: a dispenser member ( 10 ); a fluid reservoir ( 30 ); a fastener element ( 20 ) for fastening said dispenser member ( 10 ) onto a neck ( 35 ) of said reservoir ( 30 ); and a turret ( 40 ) disposed between a body ( 11 ) of the dispenser member ( 10 ) and said fastener element ( 20 ), wherein said turret ( 40 ) includes a deformable radial flange ( 45 ), said deformable radial flange having deformable sealing means ( 46 , 47 ) projecting from said radial flange ( 45 ), wherein said radial flange ( 45 ), before assembly, curves upwards, and after assembly, is deformed and co-operates in leaktight manner with the top edge of the neck ( 35 ) of the reservoir ( 30 ) so that said radial flange ( 45 ) is radially flat between, and in contact with, the fastener element ( 20 ) and the neck ( 35 ) of the reservoir ( 30 ), and said sealing means ( 46 , 47 ), after assembly, is also deformed and co-operates in leaktight manner with said fastener element ( 20 ) wherein said deformable sealing means includes two projections ( 46 , 47 ) extending, before assembly, axially and parallel to each other, wherein said fastener element ( 20 ) includes an approximately cone-shaped profile ( 25 ), and after assembly, the two projections ( 46 , 47 ) co-operate in leaktight manner with said approximately cone-shaped profile ( 25 ), the tip of the cone being disposed between said two projections ( 46 , 47 ).
