Abstract
A container for heating a food product. The container comprises a base layer of material and a liner releasably attached to an inner surface of the base layer. The liner is separable from the base layer after heating the container. The container comprises a bottom panel, and end panel foldably connected to the bottom panel, a side panel foldably connected to the bottom panel, and a corner panel foldably connected to the bottom panel. The corner panel extends between the end panel and the side panel.

A container for heating a food product, the container comprising:
- a base layer of material and a liner releasably attached to an inner surface of the base layer, wherein the liner is separable from the base layer after heating the container;
- a bottom panel;
- an end panel foldably connected to the bottom panel;
- a side panel foldably connected to the bottom panel;
- and
- a corner panel foldably connected to the bottom panel, the corner panel extending between the end panel and the side panel.
In combination, a blank and a liner material for forming a container for heating a food product, the blank comprising:
- a bottom panel;
- an end panel foldably connected to the bottom panel;
- a side panel foldably connected to the bottom panel;
- and
- a corner panel foldably connected to the bottom panel, the corner panel being disposed between the end panel and the side panel so that the corner panel extends between the end panel and the side panel when the container is formed from the blank and the liner material;
- wherein the blank is for forming a base layer of the container, and the liner material is for being releasably attached to an inner surface of the base layer when the container is formed from the blank and the liner material so that the liner is separable from the base layer after heating of the container formed from the blank and the liner material.
A method of forming a container comprising:
- obtaining a blank comprising a bottom panel, an end panel foldably connected to the bottom panel, a side panel foldably connected to the bottom panel, and a corner panel foldably connected to the bottom panel;
- forming the blank into an initial construct by folding the end panel, the side panel, and the corner panel with respect to the bottom panel so that the corner panel extends between the end panel and the side panel;
- and
- applying a liner material to an inner surface of the initial construct so that the liner material and the initial construct form a respective liner and base layer of the container and so that the liner is releasably attached to the inner surface of the base layer, the liner being separable from the base layer after heating of the container.
