[0001] The invention relates to a dosing device for dosing liquid or pasty products, in particular foodstuffs, with at least one dosing unit which comprises at least one dosing nozzle, in particular movably mounted along a vertical direction, for filling containers, in particular cups, with at least one cleaning unit at least for cleaning and / or sterilizing the dosing nozzle, with at least one sterile chamber which at least partially surrounds a packaging carrier, in particular with containers arranged therein, and with at least one dosing chamber, in particular arranged along a vertical direction above the sterile chamber, in which at least the cleaning unit is arranged.

[0002] Such a dosing device is already known from DE 10 2017 207 073 A1, wherein in the already known dosing device, the dosing chamber and the sterile chamber form a common chamber, wherein this common chamber is closed at the top by a membrane arranged on the dosing unit and at the bottom by a tray to a machine interior. The dosing chamber of the already known dosing device does not comprise a floor that spatially separates the dosing chamber from the sterile chamber. A separate closure of the sterile chamber, in particular for changing the dosing unit, by means of a closable dosing opening between the dosing chamber and the sterile chamber is therefore not provided for in the already known dosing device.This can lead to unwanted contamination of the sterile chamber, particularly after a change of the dosing unit, so that additional effort for sterilization of the sterile chamber can be incurred, particularly after a change of the dosing unit.

[0003] Furthermore, a method for operating a dosing device is already known from US 6 305 438 B1.
