Abstract
Abstract A one-piece tray for displaying and packaging candy and the like in boxes. It is formed from a sheet of thermoplastic material and has cups of various configurations for receiving candy and the like. The cups are separated from each other by upstanding hollow ribs, and the tray has a vertical flange extending around the periphery thereof. In accordance with the present invention, a vertically extending flange carries a plurality of resilient, outwardly extending spaced projections of the resilient rigid thermoplastic material. When the tray is inserted in the box, the projections are flexed downwardly or upwardly against the sides of the box, exerting a transverse spring effect that stabilizes the tray in the box to absorb energy and prevent shaking of loose fitting trays against the sides of the box.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
150 words
A one-piece tray for displaying and packing candy and the like in boxes, which comprises a candy-receiving portion having a plurality of cups of desired configurations for receiving the candy or frangible articles, each cup being separated from an adjacent cup by upstanding hollow ribbed portions formed from the peripheral walls of the adjacent cups, a generally vertical flange extending around the periphery of the cup portion of the tray and forming the periphery of said tray, said vertically extending flange carrying adjacent the upper edge thereof a plurality of resilient (outwardly extending) projections spaced thereon and from each other, said projections normally extending horizontally out from said edge of said flange, said tray being entirely formed of one-piece thermoplastic resinous composition having a glass transition temperature greater than 60* C., whereby when said projections are flexed downwardly or upwardly they exert a transverse spring effect against the flexing force.
Claim 2
Dependent Claim
150 words
A one-piece tray for displaying and packing candy and the like in boxes, which comprises a candy-receiving portion having a plurality of cups of desired configurations for receiving the candy or frangible articles, each cup being separated from an adjacent cup by upstanding hollow ribbed portions formed from the peripheral walls of the adjacent cups, a generally vertical flange extending around the periphery of the cup portion of the tray and forming the periphery of said tray, said vertically extending flange carrying adjacent the upper edge thereof a plurality of resilient (outwardly extending) projections spaced thereon and from each other, said projections normally extending horizontally out from said edge of said flange, said tray being entirely formed of one-piece thermoplastic resinous composition having a glass transition temperature greater than 60* C., whereby when said projections are flexed downwardly or upwardly they exert a transverse spring effect against the flexing force.
Claim 3
Dependent Claim
20 words
The tray according to claim 1 wherein said tray is completely made of a substantially unplasticized polyvinyl chloride base composition.
Claim 4
Dependent Claim
64 words
The combination of (1) a box having a bottom and vertically extending sidewalls, (2) a one-piece tray according to claim 1 being disposed in said box, said box and said tray being proportioned and shaped so that said projections on said tray are maintained in a deflected position continuously exerting a force in springlike fashion against the adjacent vertical wall of the said box.
