Abstract

A lidding device ( 102 ) includes a first panel ( 104 ) comprising a lid ( 106 ) configured to cover and seal a food container ( 108 ). A second panel ( 110 ) is foldably connected to the first panel. A third panel ( 112 ) includes a bottom panel opposite the lid, wherein the second panel is foldably connected to the first panel and the third panel. A fourth panel ( 114 ) is foldably connected to at least one of the first panel and the third panel, wherein the fourth panel and second panel are configured to at least partially enclose a food container between the second and fourth panels.

First claim

What is claimed is:

1. A lidding device, comprising: a first panel comprising a lid configured to cover and seal a food container; a second panel foldably connected to the first panel; a third panel comprising a bottom panel opposite the lid, wherein the second panel is foldably connected to the first panel and the third panel; and a fourth panel foldably connected to at least one of the first panel and the third panel, wherein the fourth panel and second panel are configured to at least partially enclose a food container between the second and fourth panels, wherein one portion of the lid extends into the second panel and another portion of the lid extends into a fifth panel foldably connected to the first panel.

2. The lidding device as recited in claim 1 , further comprising the food container, sealed to the first panel, wherein the food container is at least partially enclosed between first panel and the third panel and between the second panel and the fourth panel.

3. The lidding device as recited in claim 2 , wherein an insulation space is defined between the food container and at least one of the first, second, third, and fourth panels.

4. The lidding device as recited in claim 3 , further comprising side flaps foldably connected to at least one of the first and third panels configured for adhering the first panel to the third panel.

5. The lidding device as recited in claim 4 , wherein the first panel, second panel, third panel, fourth panel, and side flaps completely enclose the food container.

6. The lidding device as recited in claim 2 further comprising: two opposed panels foldably connected to the first, second, third, and fourth panels, wherein each of the two opposed panels includes a cutout, which receives a respective edge of the food container.

7. The lidding device as recited in claim 1 , wherein the first panel includes a venting system including one or more lines of weakness along an edge of the first panel for venting the first panel.

8. The lidding device as recited in claim 1 , wherein the first panel further comprises a pull tab for peeling back the first panel along one or more lines of weakness along the first panel edges.

9. The lidding device as recited in claim 1 , wherein the second panel is configured for use as a foot that allows the lidding device to stand upright on the second panel.

10. The lidding device as recited in claim 1 , wherein at least one of the panels is configured to be printable for printing product identifying material or instructions thereon.

11. The lidding device as recited in claim 1 , wherein at least the first panel comprises a thermoplastic or heat sealable coating applied to a food-facing side of the panel.

12. The lidding device as recited in claim 11 , wherein the thermoplastic coating comprises a polyolefin dispersion or a polymeric-based film.

13. A method of forming a lidding device, comprising: providing a printable or pre-printed paperboard material; forming a multi-panel blank from the paperboard material, wherein the panels are separated via lines of weakness; applying a thermoplastic heat seal coating to at least a portion of one side of the blank; fitting the blank around a container to surround the container between at least a top panel and an opposed bottom panel and between a first side panel and an opposed second side panel, wherein the top panel defines a lid, extending a portion of the lid into the first side panel and the second side panel; and heat sealing the thermoplastic heat seal coating to the container.

14. The method as recited in claim 13 , further comprising applying one or more coatings to the paperboard material.

15. The method as recited in claim 14 , wherein the one or more coatings comprises a clay coating.

16. The method as recited in claim 14 , wherein applying the one or more coatings comprises applying a thermoplastic heat seal coating to at least a portion of one side of the blank.

17. The method as recited in claim 13 , wherein the paperboard material is pre-printed with marketing graphics with heat resistant microwaveable inks and/or overprint.

18. The method as recited in claim 13 , wherein fitting the blank around the container includes completely surrounding the container inside the blank.

19. The method as recited in claim 13 , wherein fitting the blank around the container includes protruding two edges of the container through cutouts in opposed flaps of the blank.

20. The method as recited in claim 13 , wherein fitting the blank around the container includes forming at least one insulation space between the container and the panels of the blank.

21. The lidding device as recited in claim 1 further comprising: a paper container sealed to the food container, wherein the paper container surrounds the food container on at least four sides of the food container, wherein there is an insulation space defined between the food container and the paper container.
