ABSTRACT:
Collapsible box-like cartons of the type constructed to fold flat for storage and to be unfolded to form a rigid carton for shipping purposes are provided with secondary hinge and removable sections which thereby enable such cartons to be transformed from their first substantially rectangular geometric shape in which they are used as shipping cartons to a second useable shape so that they can be recycled for other purposes.
