German researchers have received a U.S. patent for an absorbent incontinence diaper with an improved closure system. The article comprises: a main part having an inner face directed toward a user body and an outer face directed away from the user body, said main part having an absorption body and a backsheet on a side of said absorption body directed away from the user body, said absorption body having a smaller width than said backsheet, said main part also having a rear area, a front area and a crotch area lying between said rear area and said front area, said main part further defining first and second side edges; side parts joined to said first and said second side edges, said side parts having an inner face and an outer face; and mechanical closure means having mechanical closure aids, said closure means cooperating with said side parts at said rear area, said closure means being structured and dimensioned for detachable fastening to said outer face of said main part and to said outer face of said side parts in said front area, wherein retaining forces between said mechanical closure means and said outer face of said main part are lower than retaining forces between said mechanical closure means and said outer face of said side parts in said front area, wherein said side parts in said front and/or said rear area are folded upon themselves at least about one folding line extending in a longitudinal direction.
