摘要
The bag has a plastic flange (1) for connection of the bag with sucking nozzles of a vacuum cleaner. The flange has an opening (3) with an edge at which a seal (4) is provided to seal a connection between the flange and the nozzles. The seal lies completely in a plane of the flange in a condition, and a part of the seal lies at outside of the supports in another condition. A radial inner section of the seal exhibits an acute-angled cross-section and strength that is smaller than that of the flange. The section is arranged both on upper and lower sides of the flange that is made of elastomer.
