Abstract (en)
[origin: EP0694480A1] The packaging is formed from a cut-out sheet of cardboard which is folded to form four side panels, four upper flaps (5) and four lower flaps (4). Two opposite sides each have folding lines, and there is an internal thermo-retractable pocket closed on three sides. The pocket is fixed onto the lower flaps of two opposite sides, so that during erection of the cardboard to form the box the pocket opens and is so held. The pocket and flaps are fixed by heat sealing glue. The pocket has bevelled corners situated between two closed sides. The heat sealing glue is inactive at ambient temperature up to about 50 degrees C. This allows transportation of the packaging without the flaps adhering to each other. <IMAGE>
