Abstract: An absorbent article with an absorbent body enclosed between inner and outer casing sheets and a stiffening element extending from the rear, through the intermediate, and into the front part of the article. The stiffening element's front and rear parts are broader than its intermediate part and the stiffening element is not wider than 4 cm at its front to intermediate transition region. Side flaps are formed by at least some parts of the remainder of the article which extend laterally beyond the stiffening element, so that the distance between side-edges of the stiffening element and an edge of the side flap varies within the region. The stretch resistance of the side flaps is greater than the stiffening element's longitudinal bending resistance, so inward pressing of the side flaps causes the stiffening element to curve longitudinally, to obtain an upwardly concave shape adapted to the shape of a wearer's body.

Abstract: The invention relates to an absorbent article such as a sanitary napkin, an incontinence guard or a panty-liner, which article has a generally elongated shape with a longitudinal direction and a transverse direction and exhibits two long sides, two short sides, two end portions and a central portion, located between the end portions, and exhibiting a transversely extending cross-sectional line from which the width of the article increases in a direction towards a short side of the article, whereby the end portion located at the short side exhibits a maximum width which is larger than the width of the central portion, whereby the article changes inclination at the cross-sectional line, whereby the inclination is defined by an angle between the long side of the article and a longitudinal line parallel to the longitudinal direction of the article, which article exhibits a width of the central portion which has an upper limit of 60 mm, and an angle of 30-90°, and the article has a stiffness, at least in the front portion, which exceeds 100 N measured according to ASTM D 4032-82.

Abstract: A method of improving the sealing effect against the skin of an absorbent article comprising an absorbent body disposed between liquid impermeable and liquid permeable sheets, such article having either longitudinally extending liquid barriers 28 on each side of the centre line of the permeable top sheet which have free elastic edges for contacting the skin or having a further liquid impermeable, body-contacting sheet with anal and urethral apertures around which elastic sealing edges are provided, comprises increasing the capillary pressure of the pores of said barriers/sealing edges by causing the absolute value of the negative product 2γcos#m/r to increase. This is achieved by decreasing the pore radius r and/or by increasing the wetting angle #, γ being the surface tension of the liquid to be absorbed and cos#m being the weighted mean value of cos#. A diaper or incontinence guard having such improved properties is thereby provided.

Abstract: The invention relates to an absorbent article such as a sanitary napkin, an incontinence guard, or a panty-liner, which article has a generally elongated shape with a longitudinal direction and a transverse direction and exhibits two side edges (9, 10), two end portions (6, 7), and a crotch portion (8) located between the end portions (6, 7), which article further exhibits a liquid-pervious cover layer (2), intended to be facing the user during use, and a liquid-impervious cover layer (3), intended to be facing away from the user during use. The article comprises at least within the crotch portion (8) a stiffening element (15) of a material with a very high intrinsic stiffness, whereby the article in the crotch portion (8) has an extension in the transverse direction which during use of the article is between 40 mm and 15 mm and preferably is between 20 mm and 35 mm.

Abstract: The invention relates to an absorbent article such as a sanitary napkin, an incontinence guard, or a panty-liner, which article has a substantially elongated shape with a longitudinal direction and a transverse direction and also exhibits two side edges (9, 10), a front edge (11) and a rear edge (12), a front portion (6) and a rear portion (7), and a crotch portion (8) situated between the front portion (6) and the rear portion (7), which article furthermore exhibits a liquid-impervious surface (2) and a liquid-impervious surface (3). At least within the front portion (6) and the crotch portion (8), the article exhibits high bending stiffness against bending along transversely extending bending lines, whereby the front portion (6) and the crotch portion (8) of the article exhibit high shape permanence during use of the article. Furthermore, the front portion (6) of the article is angled in relation to the crotch portion (8), in a direction towards the liquid-pervious surface (2), whereby the front portion (6) forms and angle alpha towards the crotch portion (8) which is substantially permanent during use.

Abstract: A material laminate (1) with a planar dimension and a thickness direction perpendicular to the planar dimension, comprises a first liquid-permeable fibrous material layer (2) and a second liquid-permeable, porous and resilient material layer (3), with at least one of the material layers (2, 3) including thermoplastic material and the two material layers (2, 3) being mutually connected by the material laminate (1) exhibiting bonding sites (4) within which the thermoplastic material has been caused to at least partially soften or melt and thereby bond together the two material layers (2, 3). The bonding areas are arranged in two or more groups (5) with at least two bonding sites (4) in each group (5), with the greatest relative distance between two bonding sites (4), which are situated adjacent to each other, in a particular group (5) being less than the shortest distance between the group (5) and its closest adjacent group (5), as a result of which the material laminate (1) exhibits bond-free areas (6) between the bonding sites (4) within each bonding group (5) which have a higher density than bond-free areas (9) of the material laminate which are situated between the bonding groups (5). The laminate may be used as an outer layer on absorbent products such as nappies, panty nappies, incontinence shields, sanitary towels or bandages.
