in alinement with the outer surface of the Wall
4, thereby strengthening the corner. The tongues 5
or fingers 5 are of approximately the same thick
ness as the infolded ply 2 (Fig. 3) and terminate
adjacent to the edge of said ply 2. A strip 6 is
attached to the inner surfaces of the tongues or

and covers said tongues or fingers and consti
The lid of the box may also be formed in a
similar manner so that the side wall of the lid

The Wall 4 is designed and adapted to form
either the bottom wall of the box or the top wall
4' of the lid of the box. As shown, the wall is
substantially heart-shaped., although it may be
made in any desired shape and is provided with a
50 series of integral or attached tongues or ñngers 5
extending from its edge and adapted to be folded
at right angles to the Wall 4 against the inner
surface of the wall formed by the strip I and be- ’
