Abstract

L'invention porte sur une fermeture pour sac thermoplastique refermable présentant deux profilés se faisant face dont le premier comporte une partie longiligne solidarisable et sensiblement exempte d'interdigitations avec le deuxième profilé et dans lequel ladite partie en se déformant crée des dentelures formant des discontinuités structurelles le long du profilé. Les dentelures constituent une crête longitudinale discontinue accroissant la valeur palmographique de la fermeture tout en réduisant l'effort nécessaire à la fermeture. Lorsque les profilés s'interpénètrent, on peut percevoir un cliquetis et/ou une vibration ou une sensation de bosselage. L'invention porte également sur un procédé et un appareil de fabrication de ladite fermeture consistant à extruder un profilé et à créer des dentelures longitudinales.
