The cup (1) contains a pot (11), which preferably is filled with a concentrate of nutrition (19). The pot is closed by a lid (18) and is arranged close to the bottom of the cup and held against a vertical force, which may be applied, when the lid of the pot is torn off to use the contents of the pot. The pot shows a recess (16) at its outer structure, which is correlated to a shoulder (7) of the wall of the cup. When the pot is vertically inserted the recess snaps into the shoulder and provides a mechanical fixation.
