<P>PROBLEM TO BE SOLVED: To provide a bag with a fastener easy to open and close repeatedly. <P>SOLUTION: The bag 1 with fastener is equipped with a bag body 2 including a joint portion 9 formed by joining the peripheral edges of opposite sheet bodies 4 and a spare portion 8 formed inside. On the inner surface side of the bag body 2, a band-shaped fastener 3 formed of meshing pieces 5 that meshes each other is attached to form a fastener attaching part 11. A storing portion 13 for storing an object and a portion 12 where a cut portion 18 is to be located for opening and closing the storing portion 13 are formed across the fastener attaching part 11. A sheet piece 6 is disposed inside the bag body 2 while avoiding the joint portion 9, in the portion 12. The sheet piece 6 has one side surface formed of a resin layer 14 made of a thermoplastic resin having compatibility to the sheet body 4, and the other side surface formed of an incompatible layer 15 has lower compatibility to the body sheet 4 than the resin layer 14. The sheet piece 6 includes the resin layer 14 and is deposited on one side of the sheet body 4 whose surfaces facing each other by thermal fusion. <P>COPYRIGHT: (C)2012,JPO&INPIT |
