Abstract

L'invention porte sur une fermeture à glissière avec une butée d'extrémité inférieure séparable, laquelle fermeture à glissière comprend une boîte (40B) comprenant une partie insert de boîte (40Z) dans laquelle une broche en papillon (30) est insérée. Les quatre côtés de la partie insert de boîte (40Z) sont configurés à l'aide d'une paroi avant (40C), d'une saillie de butée arrière (40E), d'une paroi côté broche de boîte (40H) et d'une saillie de butée côté séparable (40D) et, par conséquent, une large ouverture est susceptible d'être formée dans les côtés de celle-ci où sont disposés la saillie de butée arrière (40E) et la saillie de butée côté séparable (40D). La formation de la large ouverture (40J) dans une partie des quatre côtés de la partie insert de boîte (40Z) permet à la broche en papillon (30) d'être inclinée et retirée à travers l'ouverture (40J). Par conséquent, lorsqu'une opération pour ouvrir les demi-chaînes de fermeture à glissière gauche et droite dans la direction latérale est effectuée par un utilisateur, la broche en papillon (30) peut être facilement retirée de la boîte (40B) avec une faible force.
