Problems solved by technology

While elastic waistbands and other elasticized features such as barrier leg cuffs are commonly used to maintain contact and fit, these solutions are limited and leakage can still occur, especially if the wearer does not position the diaper properly This is especially true if the diaper is in place or moved out of place

[0031] introduction

[0032] As used herein in the specification and claims, the terms "central portion," "sides," "fold guides," and "winglets" refer without further limitation to those elements that are part of the absorbent core, unless otherwise specified or where It is apparent from the context that these terms refer to another layer. When these terms are further defined by "liquid management layer" (as in "central portion of liquid management layer"), they refer to these elements that are part of the liquid management layer.

[0033] As used herein, the terms "comprising" and "comprising" are open-ended terms, each specifying the presence of features described thereafter, such as components, but not excluding other features known in the art or disclosed herein, such as Existence of elements, steps, parts. These terms based on the verb "to comprise" should be read to encompass the narrower term "consisting essentially of" which excludes any element, step or ingredient...

Abstract

An absorbent article (20), such as a diaper, comprising a topsheet (24), a backsheet (25) and an absorbent core (28). The absorbent layer comprises a longitudinally-extending central portion (60), and a first and second side portions (61, 62) disposed transversally outward of the central portion. The absorbent core further comprises first and second folding guides (261, 262) between the central portion and the side portions. The central portion and the side portions form a three-dimensional basin when the absorbent core is folded along the folding guides. The article further comprises at least one liquid management layer (52, 54) substantially free of superabsorbent polymer between the topsheet and the absorbent core. The liquid management layer comprises a central portion (60', 60''), first and second side portions (61', 61'', 62', 62''), and first and second folding guides (261', 261'', 262', 262'') which are at least partially superposed with the folding guides of the absorbent core.

Description

technical field [0001] The present invention relates to personal hygiene absorbent articles of the type worn in the crotch region of the wearer to absorb body exudates, particularly but not limited to baby diapers. Background technique [0002] Modern diapers generally comprise an absorbent core comprising, as absorbent material, a mixture of cellulosic fibers and superabsorbent polymer ("SAP") particles. Over the years, the relative amount of SAP in absorbent cores has increased, thus providing thinner absorbent cores. Absorbent articles with absorbent core materials which do not contain cellulose fibers (so-called airfelt-free cores) have also been proposed recently. Absorbent cores comprising a central portion and two side portions separated by fold guides have also been suggested for improving fit and reducing leakage. [0003] Typically, as absorbent articles become saturated with urine, they tend to sag in the wearer's crotch region due to the weight of the fluid. T...
