Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
92 words
A box formed of yieldable and springy foam plastic for a plate of the type having a depending annular rib around the underside and a generally frusto-conical peripheral portion extending upwardly therefrom, comprising: relatively shallow separable bottom and top portions having hollow inner sides, said bottom and top portions each having an annular ridge means on the inner side thereof, said ridge means being spaced inwardly from the peripheral flanges thereon and being oppositely directed from one another and defining therebetween nip means for yieldably embracing the peripheral portion of a plate.

Claim 3
Dependent Claim
27 words
A foam plastic box as claimed in claim 1, said ridge means having beveled free end portions for engaging flatwise against the peripheral portion of the plate.
