Patent number: 6926704Abstract: An absorbent disposable article, such as nappy pants, has a T-shaped tape attached on the outside of the article with such adhesion that the tape withstands a load of at least 25 N in the tape flap without the tape coming away from the outer layer. The tape flap is arranged in a parked state during use and can also be used to seal the article into a closed, folded package after use. When the tape flap has been freed from its parked state, the tape flap forms a stem portion of a T with the two cross-legs of the T permanently attached to the outer layer, so the tensile forces in the tape flap are taken up by the two legs. The outer layer includes a non-woven laminate, with at least one outer ply of spunbond and an inner ply of at least one meltblown.Type: GrantFiled: June 25, 2002Date of Patent: August 9, 2005Assignee: SCA Hygiene Products ABInventors: Mikael Andersson, Ken Olsson, Anna-Karin Storm
