20220370267 · 2022-11-24 ·

An absorbent article can have a topsheet layer, a backsheet layer, and an absorbent core positioned between the topsheet layer and the backsheet layer. The absorbent core can have a primary absorbent region having a first height measured from the topsheet layer facing surface to the backsheet layer facing surface and a first density, a secondary absorbent region having a second height measured from the topsheet layer facing surface to the backsheet layer facing surface and a second density, and a tertiary absorbent region having a third height measured from the topsheet layer facing surface to the backsheet layer facing surface and a third density. The first height is greater than the second height and the second height is greater than the third height. The first density is the same as the second density. The third density is greater than each of the first density and second density.

A pad capable of enhancing the fitting performance to a wearer. An absorber includes a front body portion, a back body portion, and a narrowing portion, whose width dimension is reduced, provided between the front body portion and the back body portion. A first groove extending in the front-back direction is formed in a central portion in the width direction of the absorber. A third groove extending in the width direction is formed in a central portion in the front-back direction of the narrowing portion. A second groove extending in the width direction is formed in a front side portion in the front-back direction of the narrowing portion. A fourth groove extending in the width direction is formed in a back side portion in the front-back direction of the narrowing portion.

ABSORBENT ARTICLE

An absorbent article includes an absorbent core. The article has a central longitudinal axis and a central transverse axis extending perpendicular to said longitudinal axis, the absorbent article having a front end edge and a back end edge. The absorbent article has a front portion, a back portion and a crotch portion. The absorbent core includes a coherent area disposed in at least the front portion and the crotch portion. The coherent area is in an absorbent component. The core cover includes a sealing arrangement for joining the upper and lower sides in the form of at least one sealed channel. The sealed channel is free or substantially free from absorbent material. The absorbent component includes oblong high density areas extending in the longitudinal direction at least in the front portion of the absorbent article.

Absorbent articles with channels

The present disclosure is directed, in part, to an absorbent article comprising a liquid management system (LMS) and an absorbent core disposed at least partially intermediate a topsheet and a backsheet. The LMS defines one or more channels therein. The one or more channels of the LMS may at least partially overlap or not overlap with channels defined in the absorbent core.

PROCESS AND APPARATUS FOR MAKING CHANNELED ABSORBENT ARTICLES
20230081149 · 2023-03-16 ·

A method for making an absorbent article comprising an absorbent core comprising one or more channels, the method comprising the steps of: i. providing a first endless moving surface comprising a plurality of molds typically in the form of pockets, each mold comprising an insert therein, wherein the molds are in fluid communication with an under-pressure source except for said insert such that a suction zone is formed in areas neighboring said insert; ii. feeding a first nonwoven web to said first endless moving surface and over one or more said molds; iii. depositing an absorbent material, comprising cellulose fibers and/or superabsorbent polymer particles, over at least a portion of said nonwoven web; iv. optionally further selectively removing said absorbent material from areas of the nonwoven web corresponding to said insert; v. applying a second nonwoven web directly or indirectly over the absorbent material, or folding said first nonwoven web, such to sandwich said absorbent material between upper and lower layers of said nonwoven web(s); vi. joining said upper and lower layers together at least in the areas of the nonwoven web(s) corresponding to the insert to form an absorbent core having one or more channels substantially free of absorbent material; vii. optionally joining an acquisition distribution layer to said absorbent core, typically a skin facing surface of said upper layer; viii. optionally laminating said absorbent core and acquisition distribution layer between a liquid pervious topsheet and a liquid impervious backsheet; wherein at least a portion of said insert is porous and is in fluid communication with a positive pressure source such that air is blown out of said insert to form an air cushion or air film around at least an uppermost surface of said insert and in that said absorbent material is thereby forced away from areas of the nonwoven web corresponding to said insert.

Absorbent article having outwardly convex longitudinal central channels for improved protection

An absorbent article having a pair of longitudinal edges, front and rear transverse edges, a front end region, a rear end region, and a central region disposed between the front and rear end regions. The absorbent article has a liquid pervious topsheet, a liquid impervious backsheet, an absorbent core disposed between the topsheet and the backsheet, a pair of outwardly convex longitudinal central channels formed at least in the central region. The traversal distance of the pair of outwardly convex longitudinal central channels decreases towards both ends of the channels to define a central closed area. The absorbent article has a rear channel defining a rear closed area in the rear end region.

ABSORBENT ARTICLES HAVING CHANNEL-FORMING AREAS AND WETNESS INDICATOR
20230062312 · 2023-03-02 ·

An absorbent article comprising an absorbent core having a longitudinally extending channel-forming area and a wetness indicator. The core wrap comprises a top side and a bottom side, which are attached to each other through areas substantially free of absorbent material, so that when the absorbent material swells upon absorption of a liquid a channel is formed along the area substantially free of absorbent material.

ABSORBENT ARTICLE
