Absorbent product, such as a diaper, a pant diaper, an incontinence pad, a sanitary towel or the like, comprising an absorption body (9) having a generally oblong shape with two longitudinal sides (4, 5), two transverse sides (6, 7), a longitudinal centre line (38), and also comprising a first, liquid-permeable surface layer (10) and a second, essentially liquid- impermeable surface layer (39), an essentially liquid-impermeable backing layer (8), an absorption body (9) positioned between said liquid-permeable surface layer (10) and said backing layer (8), two leakage barriers (15, 16) made of flexible material in the longitudinal direction on each side of the longitudinal centre line (38) and the first, liquid-permeable surface layer (10). Each leakage barrier (15, 16) has a first edge (45, 46) permanently fastened along the first, liquid-permeable surface layer (10) and a second edge (17, 18) which extends in the direction of the longitudinal centre line (38) of the absorbent product. Each leakage barrier (15, 16) also has a first surface (41, 42) and a second surface (43, 44). The first surface (41, 42) and/or the second surface (43, 44) of each said leakage barrier (15, 16) is fastened to or near to the first, liquid-permeable surface layer (10) and/or the second, liquid-impermeable surface layer (39).

Cette invention se rapporte à un produit absorbant, tel que couche, couche-culotte, serviette pour incontinent, serviette hygiénique ou similaire, comprenant un corps d'absorption (9) ayant une forme généralement oblongue avec deux côtés longitudinaux (4, 5), deux côtés transversaux (6, 7) et un axe longitudinal (38), et comprenant également une première couche de surface (10) perméable aux liquides et une seconde couche de surface (39) essentiellement imperméable aux liquides, une couche dorsale (8) essentiellement imperméable aux liquides, un corps d'absorption (9) placé entre cette couche de surface (10) perméable aux liquides et cette couche dorsale (8), deux barrières antifuites (15, 16) faites en matière souple dans le sens longitudinal sur chaque côté de l'axe longitudinal (38) et de la première couche de surface (10) perméable aux liquides. Chaque barrière antifuite (15, 16) possède un premier bord (45, 46) fixé en permanence le long de la première couche de surface (10) perméable aux liquides et un second bord (17, 18) qui s'étend dans le sens de l'axe longitudinal (38) du produit absorbant. Chaque barrière antifuite (15, 16) comporte également une première surface (41, 42) et une seconde surface (43, 44). La première surface (41, 42) et/ou la seconde surface (43, 44) de chaque barrière antifuite (15, 16) est fixée à la première couche de surface (10) perméable aux liquides et/ou à la seconde couche de surface (39) imperméable aux liquides ou en un point proche de celles-ci.
