Abstract: A fluid dispenser assembly having a fluid reservoir (4), a dispenser member (5), and a dispenser orifice (62). The fluid reservoir (4) includes a piston (42) movable in leaktight sliding contact in a slide cylinder (41) over a maximum stroke defined between a start position that corresponds to a substantially full state of the reservoir, and an end position that corresponds to a substantially empty state of the reservoir. The dispenser assembly further includes an RFID tag (40) that is secured to the piston (42).

Abstract: A fluid dispenser assembly comprising a fluid reservoir (4), a dispenser member (5), and a dispenser orifice (62), the fluid reservoir (4) including a piston (42) that is movable in leaktight sliding contact in a slide cylinder (41) over a maximum stroke defined between a start position that corresponds to a substantially full state of the reservoir, and an end position that corresponds to a substantially empty state of the reservoir, the dispenser assembly being characterized in that it further comprises an RFID tag (40) that is secured to the piston (42).

Abstract: A fluid dispenser having a reservoir (1), a dispenser head (T) provided with a dispenser orifice (62), a dip tube (22), a pusher (6) axially movable over a determined stroke, an electric pump (4) that delivers air into the reservoir (1) so as to force the fluid through the dip tube (22) and actuated by the pusher (6), and a fluid outlet valve (7). All of the air coming from the electric pump is delivered into the reservoir. The electric pump (4) is activated by the pusher (6) as soon as it leaves its high rest position, and the outlet valve (7) is opened only in the proximity of the low depressed position, such that the electric pump (4) is electrically powered before the outlet valve (7) is opened and delivers air into the reservoir (1) with an increase in pressure that is less than 1 Bar.

Abstract: A fluid dispenser comprising: a reservoir (1); a dispenser head (T) that is provided with a dispenser orifice (62); a dip tube (22) that conveys the fluid from the reservoir (1) to the dispenser head (T); a pusher (6) that is axially movable over a determined stroke; an electric pump (4) that delivers air into the reservoir (1) so as to force the fluid through the dip tube (22) as far as the dispenser head (T), the electric pump (4) being actuated by the pusher (6); and a fluid outlet valve (7); the fluid dispenser being characterized in that: all of the air coming from the electric pump is delivered into the reservoir; the electric pump (4) is activated by the pusher (6) as soon as it leaves its high rest position, and the outlet valve (7) is opened only in the proximity of the low depressed position, such that the electric pump (4) is electrically powered well before the outlet valve (7) is opened; and the electric pump (4) delivers air into the reservoir (1) with an increase in pressure that is less than 1
