WATERPROOF ZIP, AND METHOD FOR PRODUCING A WATERPROOF ZIP

摘要

The invention concerns a waterproof zip closure comprising two rows of teeth, each row being joined to a tape, the rows of teeth being brought into engagement with each other and separated from each other by a slide. In the vicinity of the rows of teeth, the zip closure has sealing means which, when the zip is closed, are pressed against each other, thus forming a seal. The sealing means consist of an elastic rubber or plastics material disposed between the individual teeth. Between the elastic rubber or plastics material and the tape, and optionally also the teeth, there is an intimate join produced by adhesive bonding or vulcanization. The invention also concerns a method of manufacturing a zip closure of this kind.
