Abstract
Abstract A recyclable and reusable container for shipping and stacking glass sheets includes a creased recyclable cardboard piece forming the rear and two sides of the container, with underflaps connected to a reusable wooden pallet; an easily removable front wall without underflaps and made of the same recyclable cardboard; recyclable cardboard corner posts and recyclable cardboard cross-members resting on top of the glass sheets flush with the top of the container. The container, without vertical wooden or metal structures, can support other containers filled with glass sheets stacked on top due, in part, to the use of the glass sheets as load-bearing members during stacking.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
171 words
A stackable, substantially rectangular container for shipping sheets of glass wherein said glass sheets, when placed in said container, form load-bearing members when one container is stacked upon another, said container comprising: a reusable base pallet; a first integral sheet of recyclable corrugated cardboard creased appropriately so as to form two sides and the rear wall of said container, as well as three bottom flaps for connecting said sheet to said pallet; a second sheet of recyclable corrugated cardboard, said second sheet forming the front wall of said container; generally L-shaped corner posts of recyclable corrugated cardboard for each corner of said container; and horizontal cross-member means of recyclable material extending between two opposing walls of said container and located on top of said glass sheets when placed in said container, so as to bear a portion of the load of another container when stacked thereupon, thereby transferring a portion of said load into said glass sheets, whereby said glass sheets bear a portion of the load caused by said stacking.
Claim 2
Dependent Claim
171 words
