Abstract

A container for supporting a food product includes a tray and a liner. The tray includes a plurality of panels at least extending at least partially around an interior of the tray, the plurality of panels comprising a bottom panel, at least one side panel, at least one end panel, and at least one corner panel. The liner includes a central panel and at least one marginal panel each foldably connected to a gusset. The container is reconfigurable between a first configuration in which the at least one end panel and the at least one corner panel are in generally planar overlying relation with the respective bottom panel and the at least one side panel, with the liner positioned therebetween and with the gusset in a folded arrangement, and a second configuration in which the at least one side panel, the at least one end panel, and the at least one corner panel are generally upright relative to the bottom panel with the gusset in an expanded arrangement.

First claim

What is claimed is:

1. A container for supporting a food product, the container comprising:
a tray, the tray comprising:
a plurality of panels at least extending at least partially around an interior of the tray, the plurality of panels comprising a bottom panel, at least one side panel, at least one end panel, and at least one corner panel; and
a liner attached to the tray, the liner comprising:
a central panel and at least one marginal panel each foldably connected to a gusset,
the container is reconfigurable between a first configuration in which the at least one end panel and the at least one corner panel are in generally planar overlying relation with the respective bottom panel and the at least one side panel, with the liner positioned therebetween and with the gusset in a folded arrangement, and a second configuration in which the at least one side panel, the at least one end panel, and the at least one corner panel are generally upright relative to the bottom panel with the gusset in an expanded arrangement.

2. The container of claim 1 , wherein the at least one end panel is in at least partial face-to-face contact with a portion of the at least one corner panel.

3. The container of claim 2 , wherein the at least one side panel is attached to the at least one corner panel such that when the container is reconfigured between the first configuration and the second configuration, movement of the at least one end panel causes movement of the at least one side panel.

4. The container of claim 2 , wherein the at least one corner panel comprises an end section separated from the at least one end panel at a cut and a side section foldably connected to the at least one side panel at a fold line.

5. The container of claim 4 , wherein the gusset of the liner comprises a first gusset panel foldably connected to the at least one marginal panel and a second gusset panel foldably connected to each of the first gusset panel and the central panel.

6. The container of claim 5 , wherein, in the folded arrangement of the gusset, a portion of the at least one marginal panel is in face-to-face contact with the first gusset panel, the first gusset panel is in face-to-face contact with the second gusset panel, and the second gusset panel is in face-to-face contact with a portion of the central panel.

7. The container of claim 6 , wherein, in the folded arrangement of the gusset, a portion of the at least one marginal panel is in face-to-face contact with a portion of the central panel.

8. The container of claim 2 , wherein, in the second configuration of the container, the at least one marginal panel extends past a top edge of the at least one side panel.

9. The container of claim 1 , wherein the at least one marginal panel of the liner is a first marginal panel foldably connected to a first gusset, and the liner further comprises a second marginal panel foldably connected to a second gusset, each gusset foldably connected to the central panel.

10. The container of claim 9 , wherein each gusset comprises a first gusset panel foldably connected to a second gusset panel, the second gusset panel foldably connected to the central panel.

11. The container of claim 10 , wherein the at least one corner panel is a first corner panel and the at least one end panel is a first end panel separated from the first corner panel, the at least one side panel is a first side panel foldably connected to the first corner panel, and the plurality of panels further comprises a second end panel, a second corner panel foldably connected to the first side panel and separated from the second end panel, a second side panel, a third corner panel separated from the second end panel and foldably connected to the second side panel, and a fourth corner panel separated from the first end panel and foldably connected to the second side panel.

12. The container of claim 11 , wherein each corner panel comprises an end section foldably connected to a side section.

13. The container of claim 1 , wherein the tray is formed from paperboard and the liner is formed from a polymeric material.

14. In combination, a blank and a liner for forming a container for supporting a food product, the combination comprising:
the blank, the blank comprising a plurality of panels for at least extending at least partially around an interior of a tray formed from the blank, the plurality of panels comprising a bottom panel, at least one side panel, at least one end panel, and at least one corner panel; and
the liner attached to the blank, the liner comprising a central panel and at least one marginal panel each foldably connected to a gusset,
the blank and the liner are for being formed into the container, with the container being reconfigurable between a first configuration in which the at least one end panel and the at least one corner panel are in generally planar overlying relation with the respective bottom panel and the at least one side panel, with the liner positioned therebetween and with the gusset in a folded arrangement, and a second configuration in which the at least one side panel, the at least one end panel, and the at least one corner panel are generally upright relative to the bottom panel with the gusset in an expanded arrangement.

15. The combination of claim 14 , wherein the at least one end panel is for being positioned in at least partial face-to-face contact with a portion of the at least one corner panel when the container is formed from the blank and the liner.

16. The combination of claim 15 , wherein the at least one side panel is attached to the at least one corner panel such that when the container formed from the blank and the liner is reconfigured between the first configuration and the second configuration, movement of the at least one end panel causes movement of the at least one side panel.

17. The combination of claim 15 , wherein the at least one corner panel comprises an end section separated from the at least one end panel at a cut and a side section foldably connected to the at least one side panel at a fold line.

18. The combination of claim 17 , wherein the gusset of the liner comprises a first gusset panel foldably connected to the at least one marginal panel and a second gusset panel foldably connected to each of the first gusset panel and the central panel.

19. The combination of claim 15 , wherein, the at least one marginal panel extends past a top edge of the at least one side panel.

20. The combination of claim 14 , wherein the at least one marginal panel of the liner is a first marginal panel foldably connected to a first gusset, and the liner further comprises a second marginal panel foldably connected to a second gusset, each gusset foldably connected to the central panel.

21. The combination of claim 20 , wherein each gusset comprises a first gusset panel foldably connected to a second gusset panel, the second gusset panel foldably connected to the central panel.

22. The combination of claim 21 , wherein the at least one corner panel is a first corner panel and the at least one end panel is a first end panel separated from the first corner panel, the at least one side panel is a first side panel foldably connected to the first corner panel, and the plurality of panels further comprises a second end panel, a second corner panel foldably connected to the first side panel and separated from the second end panel, a second side panel, a third corner panel separated from the second end panel and foldably connected
