CA 2163738

Absorbent articles such as diapers, incontinent briefs, training pants, diaper holders and liners, feminine hygiene garments, and the like, designed to provide sustained dynamic fit about the wearer during use as well as to improve the containment of body exudates and wearer comfort/mobility. Such an absorbent article has an absorbent core preferably designed to fit within the low motion zone of the wearer so that dynamic forces imparted by movements of the wearer on the absorbent core are minimized. The absorbent article is also provided with a closure system for anchoring the absorbent article on the wearer to sustain the dynamic fit of the absorbent article throughout wearing. The closure system is designed so that a primary line of tension, fitting at an angle to the body, is formed to secure the absorbent article on a wearer. The absorbent article preferably further comprises elastic features for fitting about the extremities of the wearer, including elastic waist features, elastic leg features, and elastic side panels, that allow freedom of movement for the wearer as well as of forces about the body to sustain the fit of the absorbent article. Preferred containment assembly (chassis) designs are also provided.

Articles absorbants tels que des couches, des slips pour incontinents, des calçons d'entraînement étanches, des supports et des doublures de couches, des vêtements d'hygiène féminins et analogue conçus pour s'adapter aux mouvenents de l'utilisateur de manière prolongée, améliorer la rétention des exsudats biologiques et accroître le confort et la mobilité de l'utilisateur. De tels articles absorbants comportent une âme absorbante conçue de préférence pour s'adapter à la zone de moindre mouvement de l'utilisateur de façon à réduire au minimum l'effet dynamique des mouvements de l'utilisateur sur ladite âme absorbante. L'article absorbant est également muni d'un système de fermeture le maintenant en place et lui assurant un ajustement dynamique prolongé tout au long de l'utilisation. Le système de fermeture est conçu de manière que la première ligne de tension oblique par rapport au corps assure la fixation de l'article absorbant sur l'utilisateur. L'article absorbant comporte en outre des éléments élastiques s'adaptant au corps de l'utilisateur au niveau de la taille, des jambes, ainsi que des panneaux latéraux, associant la liberté de mouvements au maintien de forces autour du corps pour garantir l'ajustement de l'article absorbant. L'invention porte également sur des modèles préconisés d'ensembles de rétention.
