PROBLEM TO BE SOLVED: To provide a package with a sealing flap which can be reused two or more times, is devised to express a user's intention or the like for reuse, and further has improved security. SOLUTION: A plurality of sealing devices 5-1 to 5-3 consisting of pressure-sensitive agent layers 6-1 to 6-3 having pieces of release paper 7-1 to 7-3 sequentially glued to the surface from the side of a tip 4a of the sealing flap 4 and easily unsealable tapes 8-1 to 8-3 provided inside the adhesive layers 6-1 to 6-3 are provided on the internal surface of the flap 4. As a result, the sealing devices are used from the device 5-1 on the side of the tip 4a of the flap 4, thereby allowing an envelope 1 to be reused two or more times. Further, by providing an auxiliary sealing pressure-sensitive agent layer when needed, an opening of the flap 4 is formed to be narrow. COPYRIGHT: (C)2005,JPO&NCIPI
