Apparatus and method for producing absorbent structures with absorbent layers with channel(s) without absorbent material, using a first moving endless surface with specific raised strip(s) and a second moving endless surface with specific mating strip(s).

An apparatus comprises an absorbent body, a non-permeable feature, and a port feature. The absorbent body comprises a wicking feature. The non-permeable feature is coupled with the absorbent body. The non-permeable feature and at least a portion of the absorbent body are configured to fit in an opening in a paranasal sinus wall. The port feature extends through the absorbent body. The port feature defines a lumen. The wicking feature extends outwardly relative to the port lumen. During installation of the apparatus, the non-permeable feature is positioned in an opening in the paranasal sinus wall. The absorbent body is oriented such that the wicking feature is in contact with mucosal tissue in a sinus cavity defined by the paranasal sinus wall. A proximal portion of the absorbent body is positioned outside the paranasal sinus wall.

Disposable absorbent diapers are provided with improved comfort, fit and liquid transportation. The absorbent core of the disposable absorbent diapers includes at least one absorbent structure comprising a substrate layer and an absorbent layer with channels.

In an absorbent article (200), a pair of slits (40) each extending in a front and rear direction with a predetermined width is formed in an absorbent body (23) at a front and rear direction region at least at a crotch portion (C2) such that to section a first portion (11) at middle, and a second portion (12) and a third portion (12) at both sides of the first portion in a width direction, respectively, projection portions (23P) projected toward both sides in the width direction at middle in the front and rear direction of the first portion (11) are included in the absorbent body, and cavity portions (23D) in which the projection portions (23P) fit outwardly in the width direction are formed at a front and rear direction position corresponding to the projection portions (23P) in the second portion (12) and the third portion (12), respectively.

Absorbent structures for diapers are provided, comprising, immobilized onto a supporting sheet, an absorbent layer with absorbent material containing superabsorbent polymer particles and therein, in the front region, a first and a second substantially longitudinal channel, each being free of said superabsorbent polymeric particles, for improved fit and/or performance throughout the use thereof.

A sheet-like article (1) for an absorbent article of the invention includes a plurality of absorbent units (4), each including: a long base portion (2); and water-absorbent polymer particles (3) that are fixed to a surface of first side of the long base portion (2). In the sheet-like article (1), the absorbent units (4) are arranged such that the longitudinal direction thereof is oriented in one direction. When the water-absorbent polymer particles (3) absorb a liquid, the water-absorbent polymer particles (3) swell beyond the lateral side edge portions (2s), of the long base portion (2), that extend along the longitudinal direction, and a position, in the thickness direction, of each long base portion is varied from the position thereof before absorbing the liquid.

A disposable absorbent article having a longitudinal centerline and a lateral centerline generally perpendicular to the longitudinal centerline is described herein. The disposable absorbent article has a topsheet; a backsheet; and an absorbent system disposed between the topsheet and the backsheet. The absorbent system has a first and second absorbent core configured such that there is an overlap between the first and second absorbent core and a pair of outboard distances for the first and second absorbent cores.

An absorbent article comprising a liquid permeable topsheet, a backsheet, an absorbent core comprising an absorbent material and a core wrap is provided. The core comprises at least one channel-forming area that is substantially free of absorbent material. The absorbent article comprises a masking layer between the bottom side of the core wrap and the backsheet. The masking layer and the bottom side of the core wrap are only partially bonded to each other at their interface, the interface thus comprising a bonded portion and an unbonded portion, wherein the channel-forming area at least partially corresponds to the unbonded portion of the interface, so that when the absorbent material swells, the masking layer can decouple from the three-dimensional channels.

An absorbent article has an absorbent body obtained by mixing and accumulating fibers and high absorbent polymer particles. A wrapping sheet includes an intermediate part located on a front face side of the absorbent body and both side parts folded back to a back face side of the absorbent body from the intermediate part. Distal ends of the both side parts of the wrapping sheet are overlapped on the back face side of the absorbent body to form a connecting portion. A total weight of the high absorbent polymer particles is larger than a total weight of the fibers in the absorbent body. A content rate of the high absorbent polymer particles of the absorbent body increases stepwise or continuously from the back face side toward the front face side.

An elongated cylinder in place in the center of the pad to help with leaks better coverage throughout the use of the pad.
