  • Publication number: 20200046578
    Abstract: 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.

  • Patent number: 9216116
    Abstract: The present disclosure is directed, in part, to an absorbent article comprising an absorbent core disposed at least partially intermediate the topsheet and the backsheet and comprising a core wrap enclosing an absorbent material. The core wrap comprises a first material and a second material. The first material forms a C-wrap at least partially around the second material. The absorbent material comprises at least 80% of superabsorbent polymers by weight of the absorbent material. The absorbent core comprises a channel substantially free of the superabsorbent polymers and at least partially oriented in a longitudinal direction of the article. The channel has an arcuate portion facing a longitudinal axis of the article. An angle between a tangent line of the arcuate portion and the longitudinal axis is greater than or equal to 20 degrees.
