Abstract

L'invention concerne un applicateur de produit cosmétique comprenant un élément d'application qui est conçu pour prendre une configuration incurvée à partir d'une configuration droite et vice versa. L'élément d'application comprend au moins deux parties, au moins une partie étant réalisée dans une matière moins dure que la matière des autres parties. Lorsqu'une contrainte de flexion est appliquée sur l'élément d'application, en raison d'une différence de dureté dans les différentes parties de l'élément d'application, la partie possédant moins de dureté subit une déformation concave faisant fléchir l'élément d'application. Dans un second exemple, l'applicateur comprend un capuchon comprenant une surface destinée à communiquer des informations visibles à un utilisateur, sous la forme de couleurs, de graphiques et/ou de texte, cette surface étant cachée à un utilisateur à l'état non déformé de l'applicateur et visible à l'état déformé de ce dernier.
