<p>According to the invention it is recognised that common disposal vacuum cleaner bags can be used several times provided that they are cleaned carefully. To this purpose the bag end is either cut open or cut off and reclosed by a removable closure comprising two profiles between which the open bag end is clamped for closing. In a preferred embodiment one profile is a tube having a longitudinal slot for accommodation of a bending of the bag end with the other profile placed in the bend. Thus the bag end is clamped between the two profiles.</p> |
