This invention relates to packaging sheet material par
ticularly where the surfaces of such material are ?nely
?nished and must be protected against abrasion. In a
more speci?c aspect, the invention relates to a container

FIG. 2 is a sectional view of the crate of FIG. 1 taken
along the line 2-2 of FIG. 1;
FIG. 3 is an exploded sectional View corresponding
with FIG. 2 illustrating the location of sheet stock there
