1. A cartridge receptacle for producing a beverage, the cartridge receptacle comprising:
A) a mixing chamber fluidically connectable to a reservoir of a cartridge filled with a beverage substance;
B) a fluid feed for introducing a fluid from a beverage preparation machine into the mixing chamber;
C) a cover element that is reversibly connectable to the cartridge, the cover element at least temporarily closing a cartridge opening of the cartridge leading to the reservoir;
D) an outlet element reversibly connected to the cover element; and
E) a valve unit manually opened by relative movement between the cover element and the outlet element before inserting a cartridge system into the beverage preparation machine, wherein the cartridge system comprises the cartridge and the cartridge receptacle, wherein the valve unit is movable from a closed state into an open state to establish a fluidic connection between the cartridge opening and the mixing chamber to supply the beverage substance into the mixing chamber;
wherein the cover element comprises a passage opening leading to the cartridge opening;
wherein the outlet element comprises a protrusion protruding into the passage opening;
wherein the valve unit is formed by the passage opening and the protrusion;
wherein, by way of the relative movement between the cover element and the outlet element, the protrusion is configured to shift from a position closing the passage opening into a position partially opening up the passage opening; and
wherein the cartridge receptacle is configured for insertion into the beverage preparation machine to produce the beverage.
