A compactable tube comprising a band (40) that can be wound into a helix form (44) or cylindrical tube, having on the longitudinal edges thereof and in the direction parallel to the plane of the band (40) zipper teeth (42) for fixing one edge with the opposite edge. The band (40) that is not wound is maintained in a spiral (45) or reel, perpendicular or oblique to the helix, from which there is provided a slider (48) for assembling or disassembling it. The compactable tube can comprise a rotary bending nut (46) where the band (40) is inserted and which, in the rotation thereof, assembles the edge of the band (40) on the corresponding edge of the helix (44), or disassembles it therefrom, by means of the slider (48) and guide screws (49', 49). |
