A folding box which can be erected from a flat blank with a pouring flap is proposed. The pouring flap consists of a tongue (13a) which is punched out of the wall part (13) and of an inner tongue (44) which is bonded to said tongue (13a). The tongue (44) is part of a tab linked to the wall part (13) and having the tab parts (41 and 42). In the closed state, the inner tongue (44) is connected to the lid tab part (41) via the tearing perforation (49). This connection tears when the flap is opened for the first time. The pouring part is bounded laterally by opening boundary tabs (45) which are linked to the inner pouring flap tongue (44) laterally via bending folds. <IMAGE>
