SLIDE FASTENER WITH A SEPARATOR ATTACHED THERETO

摘要

An improved slide fastener with a separator attached thereto of the type including a pair of fastener stringers and a pair of insert and box supporting members constituting the separator is disclosed. A stepped portion is provided on each of the fastener stringers between the lowermost end of the fastener element and the core portion formed at the lower end part of the fastener stringer. Each of the insert and box supporting members is formed with a slit-shaped groove at its upper side wall so that when it is fixedly secured to the fastener stringer, the stepped portion abuts against the engagement groove. At the same time, the uppermost end of the insert member or box supporting member abuts the lowermost end of the fastener element. The invention improves the strength of securement of the separator elements to the fastener stringers.
