<p>Refillable dispenser comprising a reservoir (R) and an airless pump (P) mounted on the reservoir (R) so that the pump (P) creates a depression in the reservoir (R), the pump (P) comprising a pump body (1), a pump chamber, a piston (3), an inlet valve (13, 131) and an outlet valve (23) which is connected to a distribution orifice (21), the pump (P) comprising a push button (2) which can be moved in order thus to vary the volume of the pump chamber, the inlet valve (13) being connected to the reservoir (R) by a feed duct (14), the dispenser further comprising a filling valve (5) via which fluid product from a source bottle (F) can be sucked into the reservoir (R) by the depression prevailing therein, characterized in that the dispenser further comprises a shut-off member (39), separate from the inlet valve (13, 131) which is able to move between a closed position and an open position, this shut-off member (39) coming into sealed contact with a shut-off seat (132) in the closed position in order to shut the feed duct (14) off hermetically in order to maintain the depression in the reservoir (R).</p> |
