Flaps 9, 10, 12 and 13 foldable inwardly into the side plates 5 and 6 are connected with the side plates 3 and 4 via acute-angled creases 3a, 4a, 5a and 6a. Notches 15 and 16 provided on the opposite sides of the side plate 5 and the flap 9, notches 17 and 18 provided on the opposite sides of the side plate 5 and the flap 12, notches 19 and 20 provided on the side plate 6 and the flap 10, and notches 21 and 22 provided on the opposite sides of the side plate 6 and the flap 13 are respectively engaged with each other.
