Abstract

L'invention concerne une fermeture à glissière comportant une butée séparable (1), un corps de boîtier (33) comprenant un creux évidé (33d) creusé dans une face terminale d'un côté saillant du corps de boîtier (33), plus profondément qu'un bord de ruban (11d) d'un ruban de fermeture (11), et une enveloppe de ruban (33e) disposée autour d'une partie formant un bord (11e) du ruban de fermeture (11) qui se trouve dans le creux évidé (33d). Selon la présente invention, même quand la taille du corps de boîtier (33) est augmentée, comme l'épaisseur réelle du corps de boîtier (33) est réduite par le creux évidé (33d), il est possible d'éviter les cavités de retrait ou les lignes d'écoulement lors du moulage par injection du corps de boîtier (33). De plus, la position du ruban de fermeture (11) est stabilisée dans l'espace creux durant le moulage par injection, ce qui empêche le ruban de fermeture (11) d'être visible sur la surface du corps de boîtier (33). En outre, l'enveloppe de ruban (33e) assujettit une zone de liaison du corps de boîtier (33) au ruban de fermeture (11), en augmentant ainsi la force d'ancrage du corps de boîtier (33).
