Abstract

La présente invention concerne un applicateur de tampon équipé d’un tube extérieur (2) contenant un absorbeur (4) et pourvu d’une ouverture de poussée (8) permettant de faire sortir l’absorbeur (4) d’un côté de celui-ci et d’une partie tubulaire de préhension (7) de l’autre côté de celui-ci, et d’un tube intérieur (3) qui est inséré dans la partie tubulaire de préhension (7) et qui peut pousser l’absorbeur (4) hors de l’ouverture de poussée (8) vers l’extérieur par déplacement à l’intérieur du tube extérieur (2). Une pluralité de rangées de saillies annulaires (11, 12, 13, 14) est formée dans toute la zone de la partie tubulaire de préhension (7) dans la direction circonférentielle, de telle sorte que la hauteur depuis la surface circonférentielle extérieure diminue progressivement vers le côté du tube intérieur (3) qui est inséré dans la partie tubulaire de préhension (7).
