PROBLEM TO BE SOLVED: To easily re-seal a seal lid only by returning a tray into a sleeve on a sleeve carton comprising an extension of the seal lid of the tray and a sleeve which are stuck to each other by providing a protrusion on a side of a drawer of the tray and by partially sticking the protrusion to an outer rim on the side of the drawer on a top face of the sleeve. ;SOLUTION: At the time of unsealing a sleeve carton with a tray simultaneously unsealed, after a zipper of a protrusion 4a of a sleeve 1 is torn off, a part where the protrusion 4a of the sleeve 1 and a protrusion of a tray 2 have been stuck is pulled to draw the try 2 out of the sleeve 1. At the same time as the tray 2 is drawn out, a seal lid 3 is peeled from the tray 2 to be unsealed, and the tray 2 can be returned into the sleeve 1 thereby permitting the sleeve tray to be re-sealed. At this time, the sleeve 1 and an extension of the seal lid 3 are partially stuck after the tray 2 is filled with contents, wherein a part of the seal lid 3 is extended from a flange of the tray 2 at this time, the extension is inverted, and it is stuck to a rear of a top face of the sleeve 1.;COPYRIGHT: (C)2000,JPO
