Abstract

A two component shelving system for shipping and displaying items. The system has a plurality of shelves, with each shelf comprised of a two fold-down flaps, one from each component, connected together.

First claim

The invention claimed is:

1. A two component shelving system comprising:
an outer structure comprising:
two laterally opposing first and second sidewalls;
one or more elongated horizontal front panels having laterally opposing ends, each end connected to a sidewall along a first fold line;
a rear wall integrally connected to one of the sidewalls along a second fold line and adhesively connected to the other sidewall, the rear wall defining one or more rear wall slots; and
one or more shelf front flaps, each shelf front flap hingedly connected to a front panel along a third fold line, each shelf front flap comprising a tab; and

an inner structure comprising:
two vertically elongated connecting flaps adhered to the first and second sidewalls;
one or more elongated inner horizontal support panels having opposing ends connected to the vertically elongated connecting flaps along sixth fold lines; and
one or more shelf rear flaps, each shelf rear flap hingedly connected to an elongated inner horizontal support panel along a fourth fold line, each shelf rear flap comprising a tab configured to mate with a corresponding rear wall slot, each shelf rear flap defining a rear flap slot configured to receive the tab of a corresponding shelf front flap.

2. The shelving system of claim 1 wherein:
the outer structure is made from a first unitary blank and the inner structure is made from a second unitary blank.

3. The shelving system of claim 1 wherein:
the front panels, first and second sidewalls, rear wall and shelf front flaps are integral parts of the outer structure; and
the shelf rear flaps, inner horizontal support panels and connecting flaps are integral parts of the inner structure.

4. The shelving system of claim 1 wherein:
the outer structure further comprises a rear wall glue flap affixed to the rear wall along a fifth fold line.

5. The shelving system of claim 4 wherein:
the second sidewall is adhered to the rear wall glue flap.

6. The shelving system of claim 1 wherein:
the outer structure and the inner structure are made of corrugated board.

7. A two component shelving system comprising an outer structure made from a first blank and an inner structure made from a second blank; wherein
the first blank comprises a plurality of front panels, a first sidewall, a second sidewall, a rear wall, a plurality of shelf front flaps, the front panels are connected to the first sidewall and to the second sidewall along first fold lines; the first sidewall is connected to the rear wall along a second fold line; each shelf front flap is connected to a front panel along a third fold line, each shelf front flap has a rear edge and comprises a die cut tab located between the third fold line and the rear edge, the rear wall defines a plurality of vertically spaced apart rear wall slots; and
the second blank comprises a pair of vertically elongated connecting flaps, a plurality of inner horizontal support panels hingedly connected to the vertically elongated connecting flaps along sixth fold lines, and a plurality of shelf rear flaps, each shelf rear flap comprising a main panel and a shelf tab hingedly connected to the main panel along a seventh fold line, each main panel hingedly connected to a corresponding inner horizontal support panel along a fourth fold line, each main panel defining a slot for receiving the die cut tab from a corresponding shelf front flap, each shelf tab configured to cooperate with a corresponding rear wall slot to lock each rear flap in a horizontal, load bearing position.

8. The shelving system of claim 7 wherein:
the first blank further comprises a vertical glue flap affixed to the rear wall along a fifth fold line.

9. The shelving system of claim 8 wherein:
the first sidewall is adhered to one of the connecting flaps of the inner structure; and
the second sidewall is adhered to the other connecting flap of the inner structure and to the rear wall glue flap.

10. The shelving system of claim 7 wherein:
the first blank and the second blank are each made of corrugated board.

11. A method of assembling a shelving system comprising the steps of:
providing a first blank comprising a plurality of front panels, a first sidewall, a second sidewall, a rear wall, a plurality of shelf front flaps and a vertical glue flap; the plurality of front panels being connected to the first sidewall along a first set of co-linear first fold lines and to the second sidewall along a second set of co-linear fold first lines, the first sidewall being connected to the rear wall along a second fold line; each shelf front flap being connected to a front panel along a third fold line, each shelf front flap comprising a tab; the vertical glue flap being hingedly connected to the rear wall along a fifth fold line; the rear wall defining a plurality of rear wall slots;
providing a second blank comprising a pair of vertically elongated connecting flaps, a plurality of inner horizontal support panels hingedly connected to the vertically elongated connecting flaps along sixth fold lines, and a plurality of shelf rear flaps hingedly connected to the inner horizontal support panels along a fourth fold line; each shelf rear flap comprises a main panel defining a slot for receiving the tab from a corresponding shelf front flap and a rear flap tab hingedly connected to the main panel along a seventh fold line;
adhering one of the vertically elongated connecting flaps of second blank to the first sidewall of the first blank;
folding the first blank along the first fold lines and the second fold line;
adhering the second sidewall to the glue flap;
rotating each shelf rear flap along a fourth fold line until each rear flap tab is inserted into a corresponding rear wall slot; and
rotating each shelf front flap along a third fold line until each front flap tab is inserted into a rear flap slot.
