  • Fabrication method for disposable articles and a liquid-absorbing disposable article
    Patent number: 4595441
    Abstract: A fabrication method for a disposable article and a disposable article for absorbing liquids.This method consists in cutting an impermeable foil (35) so as to form two strips (35a) and (35b) in the median zone of said foil along a tracing of a sequence of equal straight-line segments parallel to the longitudinal axis of the foil and staggered alternatingly on either side of said axis. The strip (35a) is laterally shifted by a distance slightly less than the distance between the segments located on either side of the axis XX'. The strip (35b) follows a path which is longer than that of the strip (35a) by the repeat of the cut-out. The strips (35a) and (35b) then are deposited on the absorbing portions (34) in such a manner that the permeable zone is located in the central region of said portion.The obtained sheath is cut into individual articles.

  • Disposable diaper
    Patent number: 4589878
    Abstract: A disposable diaper for incontinent adults comprising an absorbing pad covered by a liquid-impermeable external sheet (3) and a non-woven liquid-permeable inside sheet (4). This diaper is provided with four longitudinal folding lines, whereby it can be folded into several superposed levels (7a, 7b, 7c) when in the position of usage. Stretched elastic cords (13a) and (13b) are inserted between the sheets (3) and (4) near and parallel to the longitudinal edges. Prior to use two elastic belts (14a, 14b) are fixed on the same longitudinal edge (9a), one in the front zone (12) and the other in the rear zone (11) so as to clamp the cord (13a). The diaper has improved hermeticity and facilitates its emplacement by the user.
