Abstract: The invention relates to a pourer (1) of a container comprising a pouring nozzle (2) which forms a pouring channel and on the external thread (3) of which a covering cap (4) is screwed. A sealing stopper (6) which closes the pouring channel is guided non-rotatably and is vertically displaceable in the pouring channel of the pouring nozzle. The sealing stopper (6) is retained on the cap which is rotatable relative thereto, such that a screwing on of the cap leads to a lifting of the sealing stopper (6) in the pouring channel. The cap (4) has an upper opening in which the sealing stopper (6) lies with the upper end thereof. The upper end of the sealing stopper (6) has at least one tamper-evident part (7) which breaks off or breaks up when the cap is unscrewed relative to the non-rotatably retained sealing stopper.
