Abstract: A pouring device for a canister-shaped container (1) having a pouring spout (4) which can be sealed by a sealing cap (6) is described which receives a retaining ring (7) for an aeration pipe (8) running at least approximately parallel to the retaining ring (7), which is set thereon in the upper peripheral section of the retaining ring (7) relative to the pouring position. In order to create advantageous pouring conditions it is proposed that the aeration pipe (8) is sealed at its end (9) averted from the retaining ring (7) and in the vicinity of its upper peripheral section in the pouring position exhibits at least one through opening (10) terminating in the container (1) having a smaller through cross-section than the internal pipe cross-section.
