Arrays of absorbent articles having signals or combinations of signals that help communicate functional features of the component article, including the presence and/or absence of channels.

The present disclosure describes absorbent articles that include an absorbent core. The absorbent core extends longitudinally along a crotch portion of the absorbent article. The absorbent core includes a channel having one or more pathways extending longitudinally along the absorbent core. The channel is substantially free of absorbent material. In some implementations, the channel includes a single pathway. In other implementations, the channel includes multiple pathways.

A disposable absorbent article. The disposable absorbent article has a topsheet; a backsheet; and an absorbent core disposed between the topsheet and the backsheet. The disposable absorbent article exhibits a pad peel force of at least about 0.5 N, when measured in accordance with the product integrity test.

[Problem to be solved] To reduce uncomfortable feeling during wearing, and to prevent leakage from a side portion. [Solution] An absorber 4, and side sheets 7 disposed on both side portions in a longitudinal direction of a skin-contact surface side over an entire length in the longitudinal direction are provided. The side sheets 7 do not include an elastically stretchable member. There are provided a non-adhesive portion 10, in which a center portion in the width direction of the side sheets 7 is not bonded to the absorber 4 side, in a longitudinal section including a region corresponding to a body fluid discharge portion H of a wearer, and adhesive portions 11 and 12 in which side sheets 7 are bonded to the absorber 4 at an outer side in the width direction and at both end sides in the longitudinal direction of the non-adhesive portion 10. An edge of side sheet 7 in the center side in the width direction is located to the center side in the width direction from a side edge of a narrowest portion 4a of the absorber 4 in the longitudinal section including a region corresponding to a body fluid discharge portion H of a wearer. An edge in the center side in the width direction of the adhesive portion 11 adjacent to the outer side of the non-adhesive portion 10 in the width direction is provided in a position overlapped to or in the vicinity of the side edge of a narrowest portion 4a of the absorber 4.

(Object) To prevent a high compression portion from being defectively formed and also a top sheet from being torn. (Means of Achieving the Object) A sanitary napkin (1) in which a low compression portion (15) and a high compression portion (16, 17, 18) are formed on a bottom surface of a compressed groove (10) that is recessed from a skin contact surface side. The high compression portion includes regularly-arranged high compression portions (16) that are regularly arranged in a longitudinal direction of the compressed groove (10), a large-area high compression portion (17) that is irregularly arranged in the compressed groove (10) and has an area larger than an area of each of the regularly-arranged high compression portions (16), and an auxiliary high compression portion (18) that is arranged at one side, in a longitudinal direction of the napkin, of the large-area high compression portion (17) through the low compression portion (15) so as to surround the one side, in the longitudinal direction of the napkin, of the large-area high compression portion (17).

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.

An absorbent article has a top sheet, a back sheet, and an absorbent assembly positioned between the back sheet and the top sheet. The absorbent article includes a fluid intake layer positioned between the absorbent assembly and the top sheet. The fluid intake layer has a rearward-facing arch located in a back portion of the fluid intake layer. The fluid intake layer has an opening. The absorbent article includes a first lateral stiffener and a second lateral stiffener extending along a majority of the longitudinal side edges of the fluid intake layer. The absorbent article includes a first flexure, a second flexure, and a third flexure in a rear portion of the absorbent article.

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.

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.
