PROBLEM TO BE SOLVED: To provide a bag which is easy to be unsealed by hands when opening, does not have a crack generated by an impact such as dropping, and does not allow contents to leak. SOLUTION: The bag 10 has a notch 14 to serve as a starting point to unseal and a recessed open-assist line 15 for guiding the unsealing formed. The line 15 is formed to be discontinuous with the notch 14, and the notch 14 is formed only on the side of the upper end 16 of a seal 11 of a spout 12. COPYRIGHT: (C)2007,JPO&INPIT
