Title
(EN) INCONTINENCE PAD WITH VARYING THICKNESS PROFILE
(FR) SERVIETTE POUR L'INCONTINENCE À PROFIL D'ÉPAISSEUR VARIABLE
Abstract
(EN)
The urine incontinence pad (1) as disclosed herein according to a first aspect has longitudinal side edges (2, 3) extending in a longitudinal direction (L) and transverse end edges (4, 5). The incontinence pad (1) comprises a fluid permeable topsheet (8), a backsheet (9) and an absorbent core (10) being located between the topsheet (8) and the backsheet (9), the absorbent core (10) having a core front edge (10a), a core rear edge (10b), a core first longitudinal side edge (10c) and a core second longitudinal side edge (10d). The absorbent core (10) comprises a first core layer (11) and a fluid control layer (12). The absorbent core (10) in the longitudinal direction (L) has a front portion (13), a rear portion (15) and an intermediate portion (14) located between the front portion (13) and the rear portion (15). The front portion (13) and the rear portion (15) each have a length of about 30% of the total length of the absorbent core (10) and the intermediate portion (14) has a length of about 40% of the total length of the absorbent core (10) and the first core layer (11) extends over the front portion (13), the intermediate portion (14) and the rear portion (15). The fluid control layer (12) is shorter than the first core layer (11) and extends in the front portion (13) and the intermediate portion (14). The first core layer (11) comprises 100 gsm superabsorbent material or more. The absorbent core (10) has a varying thickness profile as seen in the longitudinal direction (L),with the intermediate portion (14) having a first thickness (T10.5) under a load of 0.5 kPa and a first compressed thickness (T20.5) under a load of 2.5 kPa. The rear and front portions (15, 13) each have a second thickness (T20.5)under a load of 0.5 kPa and a second compressed thickness (T22.5) under a load of 2.5 kPa, wherein the second thickness (T20.5) is from 37% to 15% of the first thickness (T10.5), the second compressed thickness (T22.5) is from 37% to 15% of the first compressed thickness (T12.5) and a ratio between the first and the second compressed thickness (T12.5/T22.5) under a load of 2.5 kPa is equal or greater than a ratio between the first and the second thickness (T10.5/T20.5), under a load of 0.5 kPa.

L'invention concerne une serviette pour l'incontinence urinaire (1) qui, selon un premier aspect, présente des bords latéraux longitudinaux (2, 3) s'étendant dans une direction longitudinale (L) et des bords d'extrémité transversale (4, 5). La serviette pour l'incontinence (1) comprend une feuille supérieure perméable aux fluides (8), une feuille arrière (9) et un noyau absorbant (10) qui est situé entre la feuille supérieure (8) et la feuille arrière (9), le noyau absorbant (10) ayant un bord avant de noyau (10a), un bord arrière de noyau (10b), un premier bord latéral longitudinal de noyau (10c) et un second bord latéral longitudinal de noyau (10d). Le noyau absorbant (10) comprend une première couche de noyau (11) et une couche de régulation de fluide (12). Le noyau absorbant (10) dans la direction longitudinale (L) a une partie avant (13), une partie arrière (15) et une partie intermédiaire (14) située entre la partie avant (13) et la partie arrière (15). La partie avant (13) et la partie arrière (15) ont chacune une longueur d'environ 30 % de la longueur totale du noyau absorbant (10) et la partie intermédiaire (14) a une longueur d'environ 40 % de la longueur totale du noyau absorbant (10) et la première couche centrale (11) s'étend sur la partie avant (13), la partie intermédiaire (14) et la partie arrière (15). La couche de régulation de fluide (12) est plus courte que la première couche de noyau (11) et s'étend dans la partie avant (13) et la partie intermédiaire (14). La première couche de noyau (11) comprend un matériau superabsorbant de 100 gsm ou plus. Le noyau absorbant (10) a un profil d'épaisseur variable vu dans la direction longitudinale (L), la partie intermédiaire (14) ayant une première épaisseur (T10,5) sous une charge de 0,5 kPa et une première épaisseur comprimée (T20,5) sous une charge de 2,5 kPa. Les parties arrière et avant (15, 13) ont chacune une seconde épaisseur (T20,5 )sous une charge de 0,5 kPa et une seconde épaisseur comprimée (T22, 5) sous une charge de 2,5 kPa, la seconde épaisseur (T20,5) étant de 37 % à 15 % de la première épaisseur (T10,5), la seconde épaisseur comprimée (T22,5) est de 37 % à 15 % de la première épaisseur comprimée (T12,5) et un rapport entre la première et la seconde épaisseur comprimée (T12,5/T22,5) sous une charge de 2,5 kPa est égale ou supérieure à un rapport entre la première et la seconde épaisseur (T10,5/T20,5), sous une charge de 0,5 kPa.
