Abstract

Abstract A carryout food tray (10) is disclosed as being constructed from a paperboard blank (12) having a central panel (16) of a rectangular shape, a pair of side panels (18) and a pair of end panels (22). Upon construction of the tray, the side panels (18) and the end panels (22) are folded upwardly from the central panel 16 and are secured to each other by tabs (28) and slots (32). The tray prevents contact between carryout food and a bag that receives the tray and also permits food to be served after the tray is removed from the bag without the possibility of the food slipping off the tray upon inclination as it is handled.

Claims Analysis

Total Claims: 10
Claim 1
Independent Claim 334 words
A carryout food tray comprising: a paperboard blank having a central panel of a rectangular shape; the blank including a pair of side panels having associated foldable scoreline connections to opposite sides of the central panel; the blank including a pair of end panels having associated foldable scoreline connections to opposite ends of the central panel; said side and end panels each having opposite ends positioned in adjacent pairs with the panel ends of each pair spaced from each other at the adjacent corner of the central panel; each side panel end including a tab; each panel end including a slot for receiving the tab on the adjacent side panel end such that the side and end panels can be folded upwardly and secured to each other at the corners of the central panel in order to prevent contact between carryout food on the tray and a bag that receives the tray and in order to also permit the food to be served on the tray after removal of the bag without the possibility of the food slipping off the tray when it is inclined; the ends of each side and end panel including edges that are inclined with respect to the associated scoreline connections thereof to the central panel; the inclination of the ends of the side and end panels being in a direction away from the adjacent panel ends such that the upwardly folded side and end panels are inclined inwardly over the central panel with the tabs and slots secured to each other; each side panel including a foldable scoreline extending parallel to the adjacent side of the central panel to define inner and outer side panel portions; the tabs being positioned on the outer portions of the side panels at the ends thereof; and the slots being inclined with respect to the scoreline connections of the end panels to the central panel to provide the outer side panel portions with a greater inward inclination than the inner side panel portions.
