Document Type and Number:
WIPO Patent Application WO/2008/041647
Kind Code:
A1
Abstract:
A band-like base (321) of a male member (32) of a fastener tape (3A) fitted to the
inner surface of a bag body (2) has a body (3211) on which an interlocking part (31)
is provided, a thin wall part (3212) joined to the opening side of the body (3211),
a thick wall part (3213) joined to the opening side of the thin wall part (3212),
and a projecting part (3214) provided on the thick wall part (3213). The female
member (33) has a structure similar to that of the male member. When the fastener
tape (3A) is fusion bonded to the bag body (2), gaps are formed between the thin
wall parts (3212, 3312) and films of the bag body (2), which facilitates bending
of the thin wall parts (3212, 3312).
