Patent

CA 2125147

A unitary disposable absorbent article (20) such as a catamenial pad or incontinent pad is provided with an elasticized side flap (30) by operatively associating an elastic member (32) on both the upper surface and the lower surface of the side flap (30). The elastic member is preferably joined to the inner surface (48) of the side flap as well as the outer surface (46) of the side flap by folding it about the distal edge (50) of the side flap. In a preferred embodiment, the elastic member (32) comprises an elastomeric laminate of an elastomeric layer (42) and a coverstock layer (44), with the coverstock layer (44) being on the outside (46) of the product, so that the sanitary napkin is provided with soft longitudinal edges (38) which contact the wearer during use. In addition, the elastomeric laminate provides relatively low tension that while raising the side flaps (30) of the product to be a barrier against lateral leakage, also maintains the product in a shape which does not encourage fluid run-off or leakage at the ends of the pad as well as providing a bunching benefit.

Article absorbant jetable unitaire (20), tel qu'une serviette cataméniale ou un coussinet d'incontinence, muni d'un rabat latéral élastique (30) créé par l'association fonctionnelle d'un élément élastique (32) sur les surfaces supérieure et inférieure du rabat latéral (30). De préférence, l'élément élastique est joint aux surfaces interne (48) et externe (46) du rabat latéral en pliant l'élément élastique autour de l'extrémité distale (50) du rabat. Dans un modèle privilégié, l'élément élastique (32) est composé du laminé élastomérique d'une couche élastomérique (42) et d'une couche couverture (44), qui (44) se trouve du côté extérieur (46) du produit, de sorte que la serviette hygiénique est pourvue de bords longitudinaux doux (38) qui touchent à la personne pendant l'utilisation de l'article. De plus, le laminé élastomérique offre une tension relativement faible qui, tout en soulevant les rabats latéraux (30) du produit pour faire office de barrière contre les fuites latérales, maintient également la forme du produit, laquelle décourage l'écoulement ou les fuites aux extrémités de la serviette et présente un retroussement avantageux.
