The invention relates to a closure stopper for containers of liquids, which is configured as a one-piece plastic part. A central degasifying vent (6) is covered on the inside by a bonded-fibre filter (7). An expansion-resistant wall (5) projects from the inner side (1a) of a ceiling wall (1) that surrounds the degasifying vent (6) on all sides at a distance. The bonded-fibre filter (7) is fixed to a protrusion (8) that is melted onto base of the expansion-resistant wall (5). |
