Foldable, leakproof multi-mode carton construction
First Claim
1. A blank adapted to be folded into a slotless carton without natural leak paths for safely containing contents such as medical waste, said blank comprising:
- center panel means for integrally forming a continuous, slotless floor of said carton, said center panel means comprising a top, a bottom, and a pair of spaced apart sides;
width panel means integral with said center panel means for forming end walls of said carton, said width panel means adjoining said center panel means at said top and said bottom;
length panel means integral with said center panel means and said width panel means for forming side walls of said carton, said length panel means adjoining said center panel means at said sides;
corner panel means for yieldably bending into said carton interior when said blank is folded into said carton, said corner panel means integral with said center panel means, said width panel means, and said length panel means; and
score line means for facilitating folding of said width panel means, said length panel means, and said corner panel means, thereby enabling the formation of said carton.

Abstract
A slotless, leakproof storage carton ideally adapted for storing medical waste and a unique blank which can be quickly folded to form the carton. Corrugated sheet stock is coated with a plastic liner and cut into blanks, which are thereafter scored. Each blank comprises a center panel, a pair of bordering width panels, a pair of bordering length panels, and four corner panels. The scoring lines comprises a first pair of spaced apart, parallel fold lines extending longitudinally, and a second pair of parallel fold lines crossing the width of the blank. Diagonal fold lines are scored into the corner panels. The center panel forms a bottom of the carton, and the width and length panels respectively form carton ends and sides. The corner panels foldably divided into separate segments which abut each other and overly the length panels. A knock down system, which permits erected cartons to be flattened, includes a knock down line which evenly bisects the blank and a cooperating pair of groups of generally triangular relief lines formed in the center panel. The assembled carton may be flattened by urging the length panels together, whereupon the width panels will fold into the carton interior. A similar deforming movement facilitated by the triangular relief lines enables the center panel to collapse outwardly from the carton. An optional, collapsible lid is preferably associated with each carton.
