ZIPPER TAPE, ZIPPER TAPE-EQUIPPED BAG, AND METHOD FOR MANUFACTURING ZIPPER TAPE-EQUIPPED BAG

WIPO Patent Application WO/2016/114304

A1

A female-side band-shaped base section (22A) with which a female-side hook section (22C) is interconnected is provided with a thin-walled section (22A1) located on the containing space (14) side, in the width direction, of the base end of the female-side hook section (22C). When inner pressure increases, the pressure acts on the base end of a second engagement section (24) and the thin-walled section (22A1) breaks off. The female-side band-shaped base section (22A) is attached only on the opening section (12) side thereof in the width direction and becomes the so-called one-side-detached state which provides excellent sealing characteristics and excellent easy-to-open characteristics. Excellent sealing characteristics and excellent easy-to-open characteristics can be achieved and manufacture can be easily performed even by a conventional attaching method which uses a zipper tape (20) having a simple structure provided with the thin-walled section (22A1) and which attaches both ends, in the width direction, of each of apair of band-shaped base sections (21A, 22A) to a bag body (10).
