Packing device for frangible material

Claim 2

A one-piece packing device for use in packing frangible sheet-like materials, comprising, a pair of spaced apart side wall sections, a top section extending between said side wall sections and defining at least one recessed area adapted to receive an edge portion of a frangible plate or the like, an intermediate section disposed interiorly of said top section and extending between said side sections, said intermediate section being spaced from said top section and located directly below said recessed area, and a truss section extending generally diagonally between said side wall sections.

Claim 3

The invention as set forth in claim 1 which includes means for operatively securing said sections to one another to provide a relatively rigid packing device.

Claim 4

The invention as set forth in claim 1 wherein all of said sections are integrally connected to one another and consist of portions of a generally flat foldable material having the sections thereof delineated in part by score lines formed in the material.

Claim 5

The invention as set forth in claim 2 wherein said fastening means comprises end flap sections integrally connected to selected of said side wall sections and adapted to be secured in a manner so as to provide a relatively rigid frangible plate supporting structure.

Claim 6

The invention as set forth in claim 1 wherein said recessed area comprises a slot formed in said top section and at least partially in said side wall sections, said slot extending generally transversely of the longitudinal axis of said packing device.

Claim 7

The invention as set forth in claim 1 wherein said packing device is fabricated of a relatively rigid yet deformable material.

Claim 8

The invention as set forth in claim 1 wherein said packing device is fabricated of a single sheet of corrugated fiber board.

Claim 9

The invention as set forth in claim 1 wherein the longitudinal edges of said top section are integrally connected to the adjacent edges of said side wall sections, wherein said intermediate section is disposed in spaced parallelism and interiorly of said top section, and wherein said truss section extends generally diagonally between one edge of one of said side wall sections and the intersection of said intermediate section with the other of said side wall sections.

Claim 10

The invention as set forth in claim 1 wherein said side wall sections comprise a pair of outer wall sections and a pair of inner wall sections, wherein said top section extends between and is integrally connected to said pair of outer wall sections and wherein said intermediate section extends between and is integrally connected to said pair of inner wall sections, and wherein said truss section extends between one edge of one of said inner wall sections and the intersection of said intermediate section and one of said pair of inner wall sections.

Claim 11

The invention as set forth in claim 9 which includes means for securing said device in a relatively rigid configuration, said means including end flap means integrally connected to said top and side wall sections and ancillary fastening means securing said end flap means together.

Claim 12

The invention as set forth in claim 9 which includes at least one tab and tab receiving recess formed in selected of said side wall and top sections for fixedly securing said sections in a relatively rigid structural configuration.

Claim 13

The invention as set forth in claim 9 wherein said top section and the adjacent portions of said outer side wall sections are formed with said recessed area which is in the form of a plate edge receiving recess.

Claim 14

The invention as set forth in claim 12 wherein the intersection of said top section and said outer wall sections are relieved adjacent said recess.

Claim 15

The iNvention as set forth in claim 8 wherein said side wall sections comprise a pair of outer wall sections and a pair of inner wall sections, wherein said top section extends between and is integrally connected to said pair of outer wall sections and wherein said intermediate section extends between and is integrally connected to said pair of inner wall sections, and wherein said truss section extends between one edge of one of said inner wall sections and the intersection of said intermediate section and one of said pair of inner wall sections.

Claim 16

The invention as set forth in claim 9 wherein said packing device is fabricated of a single sheet of corrugated fiber board.

Claim 17

The invention as set forth in claim 9 wherein said packing device is fabricated of a single sheet of corrugated fiber board material, said material being formed with a plurality of longitudinally spaced laterally extending score lines defining from one end of the material to the other: said truss section, one of said inner wall sections, said intermediate section, the other of said inner wall sections, one of said outer wall sections, said top section, and the other of said outer wall sections; said device including a plurality of end flap sections adapted to be folded into overlying relationship upon assembly of said first mentioned sections and be secured with ancillary fastening means for retaining said sections in a preselected structural configuration.

Claim 18

The invention as set forth in claim 16 wherein said outer wall sections and said top section are formed with an elongated longitudinally extending slot constituting said recessed area and adapted to form a frangible plate edge upon assembly of the device.

Claim 19

The invention as set forth in claim 16 which includes at least one hook-shaped lock portion integrally connected to one of said sections and a slot formed in another of said sections adapted to nestingly receive said hook-shaped portion for fixedly securing said device in a preselected structural configuration.
