<p>One edge portion (224) of a female side band-shaped base (221) on the side of a storage space (15) is made thick to provide a thick portion (31). A cutting portion (32) which is thinner than the female side band-shaped base (221) is provided on the storage space (15) side of the thick portion (31). A sealing base (33) is provided at the storage space (15) side of the cutting portion (32), wherein the sealing base (33) is thicker than the female side band-shaped base (221) and is to be sealed to the inner surface (10A) of a bag body (10) to which a male side band-shaped base (211) is adhered. A sealing strength of the thick portion (31) to the inner surface (10A) on which the male side band-shaped base (211) is adhered is smaller than the seal strength of the sealing base (33). The cutting portion (32) is provided to have a seal strength smaller than the seal strength of the sealing base (33). An area surrounded by the thick portion (31), the cutting portion (32), the sealing base (33), and the inner surface (10A) of the bag body (10) becomes a substantially sealed state, and thus, if a pressure is externally applied to the bag body (10) due to dropping, etc., damage due to extension of the cutting portion (32), etc., can be prevented.</p> |
