Abstract (en)
The thick portion (31) is formed thick at an end (224) of a female belt-like base (221) near a containing space (15). To the thick portion (31) near the containing space (15), a cut portion (32) thinner than the female belt-like base (221) is provided. To the cut portion (32) near the containing space (15), a seal base (33) that is thicker than the female belt-like base (221) and is sealed to an inner surface (10A) of a bag body (10) to which a male belt-like base (211) is attached, is provided. Seal strength of the thick portion (31) to the inner surface (10A) is lower than that of the seal base (33). The cut portion (32) is provided to have a lower seal strength than that of the seal base (33). An area surrounded by the thick portion (31), the cut portion (32), the seal base (33) and the inner surface (10A) of the bag body (10) becomes substantially hermetically sealed. Even when external pressure is applied on the bag body (10), e.g., when the bag body (10) is dropped, damages (e.g., stretch) to the cut portion (32) can be prevented.
