Abstract

La présente invention concerne une fermeture à glissière. Des premières parties de dent de fermeture à glissière (10) de la fermeture à glissière comprennent chacune une première partie de mise en prise (11). Des secondes parties de dent de fermeture à glissière (20) comprennent chacune une seconde partie de mise en prise (21). Les premières parties de dent de fermeture à glissière (10) et les secondes parties de dent de fermeture à glissière (20) ont des positions de mise en prise où les première et seconde parties de dent de fermeture à glissière sont mises en prise au moyen des premières parties de mise en prise (11) et des secondes parties de mise en prise (21), et des positions d'ouverture par traction dans lesquelles les première et seconde parties de dent de fermeture à glissière s'évitent l'une l'autre ; chaque première partie de dent de fermeture à glissière (10) comprend en outre une première partie de couverture (12) ; une première pointe de couverture (121) est disposée sur le côté de la première partie de couverture (12) qui est éloigné d'une première nervure de sangle (511) ; et lorsque les premières parties de dent de fermeture à glissière (10) et les secondes parties de dent de fermeture à glissière (20) sont situées dans les positions de mise en prise, les premières pointes de couverture (121) recouvrent partiellement la ligne centrale d'une seconde nervure de sangle (521). Par conséquent, un effet d'étanchéité à l'eau de la fermeture à glissière est efficacement amélioré.
