The invention relates to a dispenser system comprising a storage container (2, 102) for storing a medium, having at least one outlet valve (24), a refillable dispenser module (3, 103) having a medium chamber (31) that can be filled with a medium, having a pumping device (33) that can be actuated to discharge the medium out of the medium chamber (31) and having at least one inlet valve (35), and an actuating device, wherein the medium chamber (31) is configured as a sealed chamber having a variable volume, the dispenser module (3, 103) can be coupled to the storage container (2, 102) to fill the medium chamber (31), wherein, during filling, the at least one inlet valve (35) and the at least one outlet valve (24) are opened, either in a positively guided or pressurized manner, such that the medium chamber (31) communicates with the storage container (2, 102), the actuating device has at least one magnet (23) and at least one at least partially magnetic or magnetizable element (34) interacting with the magnet for a volume change of the meeting chamber (31) and, by means of the actuating device, during or following coupling of the dispenser module (3, 103) and the storage container (2, 102), a volume of the medium chamber (31) can be enlarged in order to produce a differential pressure between the medium chamber (31) and the storage container (2, 102), wherein a pressure in the storage container (2, 102) is higher than in the medium chamber (31) in order to convey medium out of the storage container (2, 102) into the medium chamber (31). |
