PROBLEM TO BE SOLVED: To provide a tape-fitted bag designed so as to prevent an adhesive layer from being exposed after the bag is opened. SOLUTION: Sheet-like first and second members 14 and 12 respectively are joined so as to have the shape of a bag that has an opening 11. The second member 12 has a tongue 12k extending along the opening 11. An intermediate tape 18 is stuck to the tongue 12k via an adhesive layer 16. A peel tape 22 is joined to the intermediate tape 18 via an adhesive layer 20. The peeling tape 22 is peeled, and the adhesive layer 20 of the tongue 12k is laid and stuck on the first member 14, thereby sealing the bag. After that, the tongue 12k is peeled to open the bag. Force required to peel the tongue 12k and intermediate tape 18 joined together via the adhesive layer 16 is weaker than force required to peel the intermediate taper 18 and the first member 12 stuck together via the adhesive layer 20. Thus, the tongue 12k and the intermediate tape 18 are separated to open the bag so that the adhesive layer 20 is covered with the intermediate tape 18. COPYRIGHT: (C)2009,JPO&INPIT
