'I‘he block consists essentially of a heavy outer
shell of tubular formV and one or more liner mem

one end of the tubular shell and reinforce the

Referring to Fig. '7, it will be seen that the

formed of two-ply material, the total thickness
of which is approximately three times the thick
ness of the liner piece. `The wall which is per

20|, 202, 203 and 204. Extending from the end
edges of the side flap 2|2 are tabs 225 and 226

Preferably, Wrapper |99 is applied to the blank
first, the end panel 200 being placed against the
65 end of the block and the side flaps 2| |, 2|2, 2|3
and 2 | 4 folded up and secured to the correspond
ing sides of the block. Thereafter, the tabs 225,
226, 221 and 228 are folded over and secured.
The Wrapper 99 is then applied to the block by
70 Wrapping it about the block, the fold lines |05,
|06, |01 and |08 coinciding With the corners of
the block, as indicated in Fig. 10. Thereafter,
the edge flaps Ill, ||2, ||3 and |I4 are folded
across the adjacent edge of the block and down
