Abstract: The invention relates to a device for dispensing a fluid product, including a body (1), a reservoir (10) containing one or two doses of a fluid product, said reservoir (10) including a plug (12) which closes off said reservoir (10) in a sealed manner before actuation, a dispensing head (20) provided with a dispensing orifice (21), and dispensing means for dispensing at least some of said fluid product through said dispensing orifice (21) during actuation, the plug (12) being symmetrical and reversible, and the plug (12) having an internal portion (124) which is elastically deformable and which, when pressure is applied on one axial side of said plug (12) or the other, deforms in order to open a passage (15) and, when this pressure is released, returns elastically into its resting position in which it closes off the aforementioned passage (15).

Abstract: Device for dispensing a fluid product, having a reservoir containing the fluid product and a metering valve having a valve body containing a metering chamber, a valve shut-off element sliding axially in the valve body between an rest position and a dispensing position in order to dispense the contents of the metering chamber. The valve shut-off element is urged towards its rest position by a valve spring, the reservoir containing a follower-piston and a piston spring that axially urges the follower-piston towards the metering valve, the follower-piston being suitable for axially sliding in the reservoir in a sealed manner after each actuation to compensate for the volume of each dispensed dose.

Abstract: The invention relates to a spray head for a device for dispensing a fluid product, having a body provided with a spray orifice, a central channel being connected to the spray orifice via a spray profile having a vortex chamber arranged directly upstream of the spray orifice, the spray profile having at least two curved channels extending from the central channel to the vortex chamber, each curved channel connected non-radially to the vortex chamber, to form a spray exiting the spray orifice, each curved channel having a convex shape, diverging laterally outwards from the central channel, and then from an inflection point, returning laterally inwards towards the vortex chamber.

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.
