US Patent 11285053 Absorbent article with an absorbent core having two longitudinally extending side regions and a longitudinally extending central region between said side regions and method for manufacturing said absorbent article

An absorbent article has a longitudinal direction, a transverse direction and a thickness direction, and includes a fluid permeable topsheet, a fluid impermeable backsheet and an absorbent core enclosed between the topsheet and the backsheet having, in the longitudinal direction, a front section, a rear section and a crotch section between the front section and the rear section. The absorbent core has two longitudinally extending side regions and a longitudinally extending central region between said side regions. The central region and the side regions are spaced apart in the transversal direction by longitudinally extending channel regions. Furthermore, the width of the central region in the transversal direction is less than the width of each of the side regions in the transversal direction, at least in the front section and the rear section, and the channel regions are of less basis weight than the side regions and the central region.
