Abstract
Abstract A stackable series of interconnected boxes of equal size die cut from a single cardboard blank. When assembled, the boxes are oriented in a stack so that the lid of each box faces upwardly. Access to each succeeding box is provided by the alternate hinging of successive boxes on opposite sides of the vertical stack. Each preceding box is rotated to the side to expose the lid of the next succeeding box in the stack.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
167 words
A series of interconnected parallelepiped boxes forming a stack, said series comprising: a) a bottom box, a first intermediate box and a top box in the stack, each box having a lid, a bottom panel, first and second opposing free walls and first and second opposing interconnect walls extending therebetween; b) said bottom box forming the base of the stack, the lid of said bottom box facing upward when in said stack; c) said first intermediate box having an upward-facing lid when in said stack, the first interconnect wall of the first intermediate box being hingedly attached to the vertically-adjacent second interconnect wall of the bottom box; d) said top box having an upward-facing lid when in said stack, the first interconnect wall of the top box being hingedly attached to the vertically-adjacent second interconnect wall of the first intermediate box whereby the series of boxes form a vertical stack having upward-facing lids, said lids being successively accessible upon movement of the preceding boxes in the stack.
Claim 2
Dependent Claim
167 words
A series of interconnected parallelepiped boxes forming a stack, said series comprising: a) a bottom box, a first intermediate box and a top box in the stack, each box having a lid, a bottom panel, first and second opposing free walls and first and second opposing interconnect walls extending therebetween; b) said bottom box forming the base of the stack, the lid of said bottom box facing upward when in said stack; c) said first intermediate box having an upward-facing lid when in said stack, the first interconnect wall of the first intermediate box being hingedly attached to the vertically-adjacent second interconnect wall of the bottom box; d) said top box having an upward-facing lid when in said stack, the first interconnect wall of the top box being hingedly attached to the vertically-adjacent second interconnect wall of the first intermediate box whereby the series of boxes form a vertical stack having upward-facing lids, said lids being successively accessible upon movement of the preceding boxes in the stack.
