Vacuum cleaner filter bag connecting piece has closure plate with protruding section with deformable corrugated region over at least part of length with individual wave regions in movement direction

摘要

The connecting piece has a closure plate with a protruding section with a corrugated region when viewed in longitudinal section over at least part of its length with individual wave regions in the displacement direction. A base body has a stop surface corresponding to the corrugated region, which can be deformed so that the wave region stretches when the plate is moved out of the open position when it moves against the stop surface so that it achieves a matching flat shape in the guide direction.
