Foldable, leakproof multi-mode carton construction

A leak-proof, slotless carton for safely containing contents such as medical waste, said carton comprising:

• a blank adapted to be folded to form said carton, said blank having an inner surface, an outer surface, and a predetermined length and width, 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 bordered by said width panel means and said length panel means for yieldably bending into said carton interior when said blank is folded, said corner panel means integral with said center panel means, said width panel means, and said length panel means;
• score line means defined in said blank for facilitating folding of said width panel means, said length panel means, and said corner panel means, thereby enabling the formation of said carton;
• and,
• unitary liner means permanently adhered to said inner face for insulating said carton;
• knock-down means defined in said blank for facilitating the quick collapse of said carton into a flattened configuration for convenient transport and storage;
• and,
• lid means for selectively sealing said carton.

A leak-proof, slotless carton for safely containing contents such as medical waste, said carton comprising:

• a generally rectangular, flat die cut blank adapted to be folded to form said carton, said blank comprising:
• a predetermined width and a predetermined length greater than said width;
• an inner surface bounding the carton interior and an outer surface forming the carton exterior;
• a center panel integrally forming a continuous, slotless floor of said carton, said center panel comprising a top, a bottom, and a pair of spaced apart sides;
• a pair of spaced apart width panels integral with said center panel for forming end walls of said carton, said width panels adjoining said center panel at said top and said bottom;
• a pair of length panels integral with said center panel and said width panels for forming side walls of said carton, said length panels adjoining said center panel at its sides;
• four corner panels for yieldably bending into said carton interior when said blank is folded, said corner panels integral with said center panel, said width panels, and said length panels;
• score line means defined in said blank for facilitating folding thereby enabling the formation of said carton;
• and,
• knock-down means defined in said blank for facilitating the quick collapse of said carton into a flattened configuration for convenient storage and transportation after said carton has been deployed.

A blank for forming a slotless carton without producing leak paths, said blank comprising:

• center panel means for forming a continuous, integral, slotless floor of said carton;
• width panel means integral with said center panel means and adapted to be folded perpendicularly relative to said center panel means for forming slotless end walls of said carton;
• length panel means integral with said center panel means and adapted to be folded perpendicularly relative to said center panel means for forming slotless side walls of said carton;
• and,
• means for yieldably bending into said carton interior when said width panel means and said length panel means are folded, said last mentioned means integral with said center panel means, said width panel means, and said length panel means.
