  • Patent number: 6648871
    Abstract: Absorbent article provided with a pair of belt members intended to be fastened together around the waist of the wearer and where the front portion is provided with fastening elements intended to be fastened to the belt members, such that the article will assume a pantlike shape, where the belt members form a part of the waist portions of the pant. The belt members are before use double-folded and cut in an arcuate shape whose tangent to the arcuate curve formed by respective longitudinal edges of the belt members in the area of the fold makes a substantially right angle to the fold. The folded belt members are applied to the rear portion of the article, and when the article is to be used they are unfolded, and form an arcuate shape where the portions on either sides of the fold are the mirror image of each other.
