Abstract:
PCT No. PCT/DE95/00087 Sec. 371 Date May 1, 1996 Sec. 102(e) Date May 1, 1996 PCT Filed Jan. 21, 1995 PCT Pub. No. WO95/20364 PCT Pub. Date Aug. 3, 1995A flexible paper tube, in particular a throw-away saliva suction unit for dentistry, comprises two tubular sections integrally connected to each other via a bellows and is characterized in that the paper tube (2, 6) is constructed from multi-layer paper, in particular having 3 through 15 layers and preferentially 4 to 10 layers of thickness 0.07 to 0.35 mm, in particular 0.1 to 0.2 mm and with a wall thickness between 0.2 to 2.5 mm, preferentially 0.5 to 1 mm. The fluting and folding of the bellows is preferentially done before hardening of the glued paper layers. The paper tube (2, 6) in accordance with the invention guarantees that the tube passage is not reduced in size when flexing of the tube through bending of the bellows.
