Abstract (en)

[origin: EP0216537A2] A pre-form for a box may be transported flat and then opened out to form a complete box without the need for stapling, glueing, etc. The pre-form defines four side faces 11 and 13 of the box and four flaps 18 and 24 which flaps are folded towards each other on opening out of the box to form the box bottom, which flaps also impart stability to the box. Each first flap 18 is of reduced width remote from its adjacent side face and has a slat 19 extending thereacross to form projecting tabs 19a. On folding the flaps together, the tabs 19a pass through openings in the second flaps 24 subsequently to resist bursting of the box bottom and the ends of the tabs 19a engage strip 29 of side face 11 to resist lozenging of the opened out box.
