<p>A disposable device for collecting loose material is formed from a single continuous planar blank by folding and attaching the parts of the blank together. A draw element (11) is arranged to bring shutter segments (9, 10) into a closed position. In the blank, the first wall half (14) and the second wall half (16) are folded along main fold lines (15, 16) so that the longitudinal edges (18, 19) of the wall halves overlap each other and are attached to each other by two parallel connecting lines (201, 202) placed at a distance from each other so that the draw element (11) may be passed between the first and second wall halves in a guide channel (21) formed between the connecting lines to prevent the draw element from coming into contact with the collected material.</p> |
