A dispenser system including a storage container a medium, having an outlet valve, a dispenser module having a medium chamber, a pumping device that is actuated to discharge medium from the medium chamber and having an inlet valve, and an actuating device. The medium chamber is a sealed chamber having a variable volume, and the dispenser module is coupled to the storage container to fill the medium chamber. During filling, the inlet valve and the outlet valve are opened such that the medium chamber communicates with the storage container. The actuating device has a magnet and a magnetic or magnetizable element interacting therewith for a volume change of the medium chamber. The actuating device causes a volume of the medium chamber to be enlarged to produce a differential pressure between the medium chamber and the storage container to convey medium out of the storage container into the medium chamber. |

1. A dispenser system comprising a storage vessel for storing a medium with at least one outlet valve,
a refillable dispenser module with a medium chamber which can be filled with a medium, with a pumping apparatus which has an inlet channel and can be actuated for discharging the medium out of the medium chamber, and with at least one inlet valve, and an actuating apparatus,wherein
the medium chamber is designed as a closed chamber with a variable volume, it is possible for the dispenser module to be coupled to the storage vessel for filling the medium chamber, the at least one inlet valve and the at least one outlet valve being open in a forcibly actuated or pressure-loaded manner during filling, with the result that the medium chamber communicates with the storage vessel, the at least one inlet valve and the at least one outlet valve are closed in a disconnected state of the dispenser module and the storage vessel, and it is possible for a volume of the medium chamber to be enlarged by means of the actuating apparatus during or after the coupling of the dispenser module and the storage vessel in order to generate a differential pressure between the medium chamber and the storage vessel, a pressure in the storage vessel being higher than in the medium chamber, in order to convey medium out of the storage vessel into the medium chamber,whereinthe actuating apparatus has at least one magnet and at least one at least partially magnetic or magnetizable element which interacts with the magnet for a volume change of the medium chamber. |
