Abstract
Abstract A separator for supporting stacked layers of items within a container comprising a first plastic section having a honeycomb pattern embossed on its top surface for rigidity and to distribute any applied force equally in all directions and a second plastic section joined to the underside of the first section, the separator being substantially rectangular in shape and having rounded corners to aid in expelling air trapped between successive layers of items.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
89 words
A separator for layers of items within a container to form at least first and second layers of same, comprising: (a) a first section formed of plastic material having an embossed top surface wherein said first section includes an arcuate lip about its outer periphery, said lip including a depending side wall having an inner surface; and (b) a second section formed of plastic material and being joined to the underside of said first section and having an outer edge, said depending side wall extending beyond said outer edge.
Claim 2
Dependent Claim
89 words
A separator for layers of items within a container to form at least first and second layers of same, comprising: (a) a first section formed of plastic material having an embossed top surface wherein said first section includes an arcuate lip about its outer periphery, said lip including a depending side wall having an inner surface; and (b) a second section formed of plastic material and being joined to the underside of said first section and having an outer edge, said depending side wall extending beyond said outer edge.
Claim 3
Dependent Claim
18 words
A separator as claimed in claim 1 wherein said embossed top surface comprises a plurality of juxtaposed polygons.
Claim 4
Dependent Claim
17 words
A separator as claimed in claim 2 wherein said polygons are hexagons which form a honeycomb pattern.
Claim 5
Dependent Claim
22 words
A separator as claimed in claim 3 wherein the interior of each of said hexagons is equidistantly raised above said top surface.
Claim 6
Dependent Claim
26 words
A separator as claimed in claim 1 wherein said outer edge of said second section is spaced from said inner surface of said depending side wall.
Claim 7
Dependent Claim
27 words
A separator as claimed in claim 1 wherein said outer edge of said second section is in engagement with said inner surface of said depending side wall.
Claim 8
Dependent Claim
29 words
A separator as claimed in claim 1 wherein said plastic material is extruded ABS plastic having a thickness ranging from 0.025 inches to 0.187 inches in said first section.
Claim 9
Dependent Claim
29 words
A separator as claimed in claim 1 wherein said plastic material is extruded ABS plastic having a thickness ranging from 0.010 inches to 0.125 inches in said second section.
Claim 10
Dependent Claim
27 words
A separator as claimed in claim 1 wherein said container is rectangular and wherein said side wall is adjacent at least two opposed sides of said container.
Claim 11
Dependent Claim
24 words
A separator as claimed in claim 9 wherein said separator is substantially rectangular in shape and wherein the edges of said separator are rounded.
Claim 12
Dependent Claim
78 words
A separator to be horizontally interposed between layers of items within a container, comprising: (a) a first section constructed of ABS plastic material having a first thickness and having a geometric design repetitively and uniformly formed thereon comprising a plurality of juxtaposed hexagons which form a honeycomb pattern; and, (b) a second section bonded to the underside of said first section and constructed of ABS plastic material having a second thickness which is less than said first thickness.
Claim 13
Dependent Claim
