SOLUTION: The zip fastener part 5 is attached to the separate parts of a fastener-mounted object, while the waterproof fastener part 6 is joined to the zip fastener part so that the waterproof fastener part overlaps the zip fastener part. The zip and waterproof fastener parts may be commonly fastened by one integrated sliding piece 11. The integrated sliding piece has two types of fastening channels 2 corresponding to the zip and waterproof fastener parts. The tapes with two rows of teeth-like parts of the zip fastener part are made of a thermoplastic synthetic resin fabric. COPYRIGHT: (C)2009,JPO&INPIT |
