<p>A vacuum cleaner has a dust bag a collar that engages with a flange fixture around the vacuum cleaner housing dust inlet. The flange fixture is a two-part slide (5) and collar (15) linked by an ultra-thin plastic folding unit (7) that can be presented and secured in variable (X, Y, Z) positions. The central inlet (4) seal (10) has the same material characteristics as the thin, flexible folding unit (7). The folding section (7) is a thin material e.g. flexible plastic foil. The flange inlet zone has a lip seal (10) around the inlet.</p> |
