Abstract

La présente invention concerne une fermeture à glissière dans laquelle des rangées d'éléments continus s'engrènent facilement les unes avec autres et se désengrènent les unes des autres au moyen d'un curseur se déplaçant verticalement. La fermeture à glissière est caractérisée en ce que : les éléments (301, 302) de la fermeture à glissière (1) présentent respectivement des sections de base (301c, 302c) fixées aux bandes (21, 22) de fermeture et présentent respectivement des sections de tête (301a, 302a) faisant saillie des sections de base (301c, 302c) et s'engrenant avec les éléments (301, 302) en regard ; les sections de tête (301a, 302a) des éléments (301, 302) présentent des premières sections de tête (311a, 312a) disposées sur le côté de surface supérieure (21a, 22a) et présentent également des secondes sections de tête (321a, 322a) disposées sur le côté de surface inférieure (21b, 22b) des bandes (21, 22) de fermeture ; et les premières sections de tête (311a, 312a) sont décalées dans la première direction par rapport aux secondes sections de tête (321a, 322a).
