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.

Abstract: The invention relates to a welded part (1) made from plastic between the flexible walls of a container, in particular of a bag, with a stub (3) which is formed integrally on the welded part at the top and forms a pouring channel which connects the upper pouring opening of the stub to the lower pouring channel region (3a) of the lower welded region (2), wherein a barrier layer (6) is arranged in the pouring channel, which barrier layer (6) is opened by a projection (8) of a closure cap (7) which can be screwed onto the stub (3), wherein the projection (8) of the closure cap (7), which projection (8) reaches into the pouring channel (4), is fastened to the barrier layer (6), as a result of which the barrier layer (6) is removed completely or partially when the closure cap (7) is screwed open.
