A refillable travel dispenser comprising:

• a fluid reservoir comprising a top end that forms a neck, and a bottom end that forms a filling orifice that, at rest, is closed by a valve member;
• a pump that is mounted on the top end of the reservoir so as to take fluid, wherein the pump includes a chamber and wherein the pump is contained at least in part within the reservoir;
• and
• a pusher that is mounted on the pump so as to actuate the pump;
• wherein the reservoir defines two internal compartments outside of the pump and that communicate with each other via at least one upper passage that is situated in the proximity of the top end of the reservoir, and at least one lower passage that is situated in the proximity of the bottom end of the reservoir, the valve member being movable between two seats, a rest first seat that closes the orifice of the reservoir, and a filling second seat that closes the lower passage during a filling step for filling the reservoir.
