Device for dispensing a fluid product

A device for dispensing a fluid product, comprising a body, a reservoir containing one or two doses of a fluid product, the reservoir comprising a stopper that closes off the reservoir in a sealed manner before actuation, a dispensing head provided with a dispensing orifice, and actuating means for dispensing at least a portion of the fluid product through the dispensing orifice during actuation, the dispensing head receiving an insert comprising a channel that connects, during actuation, the reservoir to the dispensing orifice, wherein:

• said stopper comprises a hollow axial sleeve suitable for sliding within said reservoir during actuation, said hollow axial sleeve being closed off before actuation by a deformable radial membrane,
• said insert comprises a point suitable for piercing said membrane of said stopper at the time of actuation, and a piston suitable for sliding in a sealed manner within the reservoir during actuation,
• characterised in that
• said point is made integrally as a single piece with said insert,
• said piston surrounds said point, and
• said membrane deforms, in particular bulges upwards, when the pressure in said reservoir increases during actuation.
