Abstract

L'invention porte sur le procédé de fabrication de l'articulation souple élastique en deux parties d'un article pour soins personnels consistant à injecter un élastomère dans une cavité (13) formée dans un manche (5) de plastique ou dans une tête (2) à une température d'au moins 245 ·C, ce qui fusionne l'élastomère et le plastique et crée l'articulation souple élastique. L'invention porte également sur un article pour soins personnels comportant une articulation souple élastique reliant un matériau plastique présentant un point de ramollissement Vicat de moins de 245 ·C à un élastomère, ledit élastomère étant fusionné au matériau plastique de manière à pouvoir être étiré jusqu'à 120 % de sa longueur à l'état non étiré sans provoquer de séparation entre l'élastomère et le plastique. L'invention assure une adhérence améliorée entre l'élastomère et le plastique permettant à l'articulation de mieux supporter les flexions répétitives. La durabilité de l'article s'en trouve améliorée.
