Abstract
A refillable travel dispenser having a fluid reservoir (1) including a top end that forms a neck (21), and a bottom end that forms a filling orifice (22) that is closed by a valve member (4); a pump (5) mounted on the top end of the reservoir (1); and a pusher mounted on the pump so as to actuate it. The reservoir (1) defines two internal compartments (C1, C2) that communicate with each other via an upper passage (31) situated in the proximity of the top end of the reservoir, and a lower passage (44) that is situated in the proximity of the bottom end of the reservoir, the valve member (4) being movable between a rest first seat (23) that closes the orifice (22) of the reservoir and a filling second seat (34) that closes the lower passage (44) during a filling step for filling the reservoir.
