<p>The invention concerns a dust filter bag (1) for a vacuum cleaner (3) having a retaining plate (H) which consists of a rigid paper material, for example cardboard, and to which a dust bag (12) is connected, for example, by adhesion. The dust filter bag (1) further has a closure flap (13) which faces the interior (15) of the dust bag (12), which is hinged on the retaining plate (H), which can be opened against the effect of a spring, and which keeps an opening (O) in the retaining plate (H) closed in the closed state. In order to configure the dust filter bag such that it has a simpler structure and can be used to greater advantage, a strip-like spring element (F) is mounted on the closure flap (13) in such a way that, in the closed state, a distance (Y) is formed between a strip end (E - E) and a hinge pin (14) of the closure flap (13), the hinge pin being disposed externally of the strip and formed such that it faces the interior (15) of the dust bag (1).</p> |
