Thereinforcement flap 96 is folded alongfold line 106 relative to theretention panel 74 such that the reinforcement flap is in a generally parallel and coplanar relationship with thereinforcement tab 44. As seen inFIG. 6 , thebottom panel 22 is folded outward along fold line 24 (in the direction of arrow A1) and thereinforcement tab 44 is folded inward along fold line 54 (in the direction of arrow A2) to create a space to receive thereinforcement flap 96. Theretention panel 74 is folded downward along fold line 84 (in the direction of arrow A3) to the assembled position in which thereinforcement flap 96 is received between thereinforcement tab 44 and thebottom panel 22. In the assembled position of one embodiment, thereinforcement flap 96 is wedged between thereinforcement tab 44 on one side and thebottom panel 22 on the other side such that the reinforcement flap is in face-to-face contact with the bottom panel and the reinforcement flap. Adhesive applied to thereinforcement tab 44 andbottom panel 22 bonds thereinforcement flap 96 to both the reinforcement tab and the bottom panel to secure theretention panel 74 in the assembled position. Theretention panel 74 is at least generally parallel to and spaced apart from thecentral panel 12 to form a receiving space 152 (FIG. 3 ) of thecarton 150. In the illustrated embodiment, theretention panel 74 at least partially encloses a corner of the tray such that the receivingspace 152 is formed in a corner of the tray. In the illustrated embodiment four receivingspaces 152 are respectively formed by theretention panels spaces 152 may be included or the receiving spaces may be otherwise shaped and/or located without departing from the invention. - In one alternative method of assembly of the
retention panel 74, thereinforcement flap 96 is positioned to the outside of thebottom panel 22. In this embodiment, thebottom panel 22 is wedged between thereinforcement flap 96 on the outside of thecarton 150 and thereinforcement tab 44 on the inside of the carton. Adhesive may be applied to any or all three of thereinforcement flap 96,bottom panel 22, andreinforcement tab 44 to hold theretention panel 74 in the assembled position. It is understood that thereinforcement flap 96,bottom panel 22, andreinforcement tab 44 may be arranged and/or assembled other than is shown in the illustrated embodiments and described herein without departing from the scope of this invention. - The upwardly folded
side panels bottom panels carton 150 cooperate to restrict the longitudinal and lateral movement of the pizza in the carton. Further, the receivingspaces 152 formed by the spacing of theretention panels central panel 12 receive a portion of the circumferential edge and margin of the pizza P to restrain the movement of the pizza away from thecentral panel 12 and to maintain the pizza in an at least generally parallel plane with the central panel. Accordingly, theside panels bottom panels retention panels carton 150. - The
carton 150 may also be used for serving a cooked food product after the food product has been removed from the carton and cooked in an oven or other cooking apparatus. In accordance with the exemplary embodiment, thecarton 150 is opened by at least partially tearing off theretention panels side panels bottom panels central panel 12 so the carton is transformed into a tray. The tray advantageously can receive and removably contain the entire cooked pizza.

The blank can also be constructed of other materials, such as cardboard, or any other material having properties suitable for enabling the carton to function at least generally as described above.
- The blank can be coated with, for example, a clay coating. The clay coating may then be printed over with product, advertising, and other information or images. The blank may then be coated with a varnish to protect information printed on the blanks. The blank may also be coated with, for example, a moisture barrier layer, on either or both sides of the blanks. The blank can also be laminated to or coated with one or more sheet-like materials at selected panels or panel sections.
- The above embodiments may be described as having one or panels, flaps, etc., adhered together by glue. The term “glue” is intended to encompass all manner of adhesives commonly used to secure paperboard carton panels in place.
- The term “line” as used herein includes not only straight lines, but also other types of lines such as curved, curvilinear or angularly displaced lines.
- In accordance with the exemplary embodiments, a fold line can be any substantially linear, although not necessarily straight, form of weakening that facilitates folding therealong. More specifically, but not for the purpose of narrowing the scope of the present invention, fold lines include: a score line, such as lines formed with a blunt scoring knife, or the like, which creates a crushed or depressed portion in the material along the desired line of weakness; a cut that extends partially into a material along the desired line of weakness, and/or a series of cuts that extend partially into and/or completely through the material along the desired line of weakness; and various combinations of these features. In situations where cutting is used to create a fold line, typically the cutting will not be overly extensive in a manner that might cause a reasonable user to incorrectly consider the fold line to be a tear line.
- The foregoing description of the invention illustrates and describes various embodiments of the present invention. As various changes could be made in the above construction without departing from the scope of the invention, it is intended that all matter contained in the above description or shown in the accompanying drawings shall be interpreted as illustrative and not in a limiting sense. Furthermore, the scope of the present invention covers various modifications, combinations, alterations, etc., of the above-described embodiments that are within the scope of the claims. Additionally, the disclosure shows and describes only selected embodiments of the invention, but the invention is capable of use in various other combinations, modifications, and environments and is capable of changes or modifications within the scope of the inventive concept as expressed herein, commensurate with the above teachings, and/or within the skill or knowledge of the relevant art. Furthermore, certain features and characteristics of each embodiment may be selectively interchanged and applied to other illustrated and non-illustrated embodiments of the invention without departing from the scope of the invention.
