An absorbent article includes a chassis with a backsheet, a topsheet joined to the backsheet, and an absorbent core disposed between the backsheet and the topsheet. The article also includes at least one handle joined to the chassis. The handle is of a material that is capable of transmitting at least 30-50% of the force applied and that recovers to substantially or nearly substantially its initial shape after forces are applied to the handle are removed. The material may be a slow recovery elastomer with a normalized unload force of greater than about 0.04 N/mm2 at 37C after a 5 minute hold time at 60% strain and a post-elongation strain of at least about 30% after 15 seconds of recovery at 22C. A method of use of the article is also included.

L'invention concerne un article absorbant contenant un châssis avec une feuille inférieure, une feuille supérieure jointe à la feuille inférieure, et un noyau absorbant disposé entre la feuille inférieure et la feuille supérieure. L'article comporte également au moins une poignée jointe au châssis. La poignée est d'un matériau capable de transmettre au moins 30-50% de la force appliquée et récupérant sensiblement ou presque sa forme initiale après relâchement des forces appliquées à la poignée. Le matériau peut être un élastomère à récupération lente avec une force de déchargement normalisée supérieure à environ 0,04 N/mm2 à 37°C après un temps de maintien de 5 minutes à une contrainte de 60% et une contrainte de post-allongement d'au moins environ 30% après 15 secondes de récupération à 22°C. L'invention concerne également un procédé d'utilisation de l'article.
