Publication number: 20200046578Abstract: An absorbent article includes a front waist edge, a rear waist edge longitudinally opposing the front waist edge, and a longitudinal axis extending from a midpoint of the front waist edge to a midpoint of the rear waist edge. The absorbent article comprises a liquid permeable topsheet, a liquid impermeable backsheet, and an absorbent core disposed at least partially intermediate the topsheet and the backsheet. The absorbent core comprises a first continuous channel and a second continuous channel, each substantially free of the superabsorbent polymers and at least partially oriented in the longitudinal direction of the absorbent. The first and second channels each have lateral widths parallel to the lateral axis. A profile of the lateral widths of each channel over a longitudinal length of at least 50 mm of the channel taken along the longitudinal axis is substantially constant. The average lateral width of the first channel differs from an average lateral width of the second channel.Type: ApplicationFiled: October 21, 2019Publication date: February 13, 2020Inventors: Donald Carroll ROE, Carsten Heinrich KREUZER, Maja WCIORKA
