Abstract

A clamshell carton wherein the tray includes a partition panel integral with the upper edge of the front wall and folded to overlie the interior of the front wall and a major portion of the bottom panel. The partition panel including a partition section selectively upwardly foldable at an intermediate and preferably central portion of the tray to define two food-receiving compartments therein.

Claims

1. A carton comprising a tray and a cover, said tray comprising a bottom panel with a periphery, front and rear walls integral with and extending upward from said periphery, side walls integral with and extending upward from said periphery between said front and rear walls, each of said walls having an upper edge, said cover being integral with and foldable relative to said tray along the upper edge of said rear wall between an open position with the cover remote from said tray and a closed position with the cover overlying said tray, and a unitary partition panel having a front edge integral with and foldable relative to said front wall along the upper edge thereof, said partition panel including a front section overlying said front wall, an intermediate section extending from said front section and engaged on and overlying said tray bottom panel, and a partition extending from said intermediate section and selectively foldable between a first position engaged on and overlying said tray bottom panel, and a second position extending upward from said intermediate section between said front and rear walls of said tray.

2. The carton of claim 1 wherein said partition, in said second position thereof, extends above said upper edges of said side walls.

3. The carton of claim 2 wherein said front edge of said partition panel is substantially coextensive with said upper edge of said front wall.

4. The carton of claim 3 wherein said bottom panel is of a predetermined width between said side walls, said intermediate section and said partition being of substantially equal width which is substantially equal to said predetermined width.

5. The carton of claim 4 wherein said partition has a free outer edge remote from said intermediate section, said free outer edge, in said first position of said partition, being forwardly spaced from said tray rear wall for facilitating access thereto.

6. The carton of claim 1 wherein said front edge of said partition panel is substantially coextensive with said upper edge of said front wall.

7. The carton of claim 6 wherein said bottom panel is of a predetermined width between said side walls, said intermediate section and said partition being of substantially equal width which is substantially equal to said predetermined width.

8. The carton of claim 6 wherein said partition has a free outer edge remote from said intermediate section, said free outer edge, in said first position of said partition, being forwardly spaced from said tray rear wall for facilitating access thereto.

9. The carton of claim 1 wherein said tray walls, upward from said periphery of said bottom panel, incline outward and are end joined.

10. The carton of claim 9 wherein said front edge of said partition panel is substantially coextensive with said upper edge of said front wall.

11. The carton of claim 10 wherein said front wall has an inner face, said front section of said partition panel being coextensive with said inner face.

12. The carton of claim 11 wherein said cover comprises a top panel with front and rear walls corresponding to said front and rear walls of said tray, and side walls corresponding to said side walls of said tray.

13. The carton of claim 12 wherein said partition panel, in said second position thereof, extends above said upper edges of said side walls, said partition being of a less height than the height of said carton between said tray bottom panel and said cover top panel in said closed position of said cover.

14. The carton of claim 9 wherein said cover comprises a top panel with front and rear walls corresponding to the front and rear walls of said tray, and side walls corresponding to said side walls of said tray, said cover side walls, in said closed position of said cover, overlying said tray side walls, said tray front wall, in said closed position of said cover, overlying said front wall, and cooperating releasable lock means on said cover and tray for releasably securing said cover in said closed position.

15. The carton of claim 14 wherein said lock means comprises keeper lugs integral and coplanar with said tray front wall and extending longitudinally thereof beyond the opposed side walls of said tray, and a lock lug integral and coplanar with each cover side wall and extending longitudinally therefrom forward of said cover front wall, said tray keeper lugs and said cover lock lugs extending mutually beyond each other at cross angles with said lock lugs, in said closed position of said cover, engaged below said keeper lugs.

16. The carton of claim 1 wherein said partition has a free outer edge remote from said intermediate section, said free outer edge, in said first position of said partition, being forwardly spaced from said tray rear wall for facilitating access thereto.

17. The carton of claim 16 wherein said bottom panel is of a predetermined width between said side walls, said intermediate section and said partition being of substantially equal width which is substantially equal to said predetermined width.

18. For use in the formation of a carton comprising a tray an cover, a planar blank of foldable sheet material, said blank having a longitudinal direction and including a bottom panel having opposed spaced transverse edges extending transversely of said blank and opposed longitudinal edges extending longitudinally of said blank, first and second wall panels extending respectively along said bottom panel first and second transverse edges, a top panel substantially dimensionally equal to said bottom panel and longitudinally extending from said second wall panel, said top panel having a third wall panel integral with said second wall panel and between said second wall panel and said top panel, said first wall panel of said bottom panel being of a progressively increasing transverse width outward of said bottom panel, said first wall panel having an outer edge of a transverse length greater than a transverse width of said bottom panel between the longitudinal edges thereof, and a partition panel integral with said outer edge of said first wall panel and extending longitudinally therebeyond, said partition panel including a first section immediately adjacent said first wall panel in the longitudinal direction of said blank, said first section having opposed end edges converging outwardly to a fold line of a transverse length substantially equal to the transverse width of said bottom panel, said partition panel including an intermediate section immediately outward of said first section and a partition section immediately outward of said intermediate section, said intermediate and partition sections being of a transverse width substantially equal to the transverse width of said bottom panel, and of a longitudinal length between said outer edge of said first section and a free outer edge on said partition panel which is less than the length of the bottom panel between said first and second wall panels thereof.
