Title:
COUPLING STRUCTURE OF FUNCTIONAL ZIPPER
Document Type and Number:
WIPO Patent Application WO/2018/225958
Kind Code:
A1
Abstract:
The present design relates to a coupling structure of a functional zipper. To this end, the present design concerns a coupling structure of a functional zipper in which a protrusion liner and a recess liner are provided inside an entrance of a storage space portion, and in which the protrusion liner and the recess liner are separated from or coupled to each other so as to open or close the entrance side of the storage space portion, said coupling structure of a functional zipper being characterized in that: in the protrusion liner, a first-side surface of a protrusion liner body having a band shape is butted against and thermally welded to the inner surface of a first-side storage member that forms the storage space portion, a rib liner having a longitudinal direction is formed on the second-side surface of the protrusion liner body and protrudes in the direction perpendicular to the second-side surface of same, and a recessed-and-protruding member is integrally formed in an end portion of the rib liner; while, in the recess liner, a second-side end portion of a recess liner body having a band shape is butted against and thermally welded to the inner surface of a second-side storage member that forms the storage space portion, and a hook liner having a longitudinal direction is integrally formed on the first-side surface of the recess liner body. Accordingly, in the present design, the storage space portion can be smoothly closed even when a foreign substance is stuck in the entrance thereof, and so the present design allows air-tight or water-tight sealing to be maintained between the inside and outside of same, and also allows a clicking sound or clicking feeling to be discerned during the course of closing, thus making it possible to reliably recognize whether closing has taken place.
