A container formed from a blank, a forming, tool and a method of forming a container are disclosed. The container includes features that are formed by a plurality of score lines in a marginal portion of the blank. The container has a bottom wall, a side wall, and a flange extending from the side wall. The flange has a thickness that is greater than a thickness of the blank.

A carton for holding a product in a liner. The carton includes a plurality of panels extending at least partially around an interior of the carton, the plurality of panels including a front panel, at least one rear panel, and at least one side panel. At least one end flap is foldably connected to a respective panel of the plurality of panels. The at least one side panel includes at least one expansion feature for transitioning the carton between a first configuration and a second configuration. The at least one expansion feature is foldably connected to the front panel and the at least one rear panel.

A microwave heating element includes a microwave antenna configured to absorb power from a microwave field in a microwave oven, a housing having a first end coupled to the microwave antenna and a second end configured to be inserted into an item to be heated, and a transmission line positioned within the housing, the transmission line having an end coupled to the microwave antenna. The transmission line is configured to spatially distribute the power absorbed from the microwave field into the item to be heated at a location between the first end and the second end of the housing.

In some embodiments, apparatuses and methods are disclosed herein useful to provide convenient, microwavable packages for cooking and crisping food products in a microwave oven are. In some embodiments, the microwavable packaged food product includes an outer package and a quantity of food product contained therein. By one approach, the package has a multilayer microwavable tray having at least three layers including a susceptor layer that includes a microwave energy interactive material thereon and a plurality of discrete openings disposed therein, an absorbent pad layer having a flexible paper-based material suitable for absorbing moisture and grease, and a paperboard base layer that provides a structure by which the susceptor layer and absorbent paper-based layer are supported. In this manner, a microwavable tray or support has at least three macro-layers including a susceptor, an absorbent pad, and a paperboard support, some of which may include additional layers therein as discussed below.

Various blanks are provided for forming sleeves, containers, and other constructs for heating, browning, and/or crisping of a food item in a microwave oven, and for holding and/or transporting the food item after heating. The various blanks, sleeves, containers, and other constructs may include a removable portion defined by one or more lines of disruption that enable the removable portion to be separated from the remainder of the blank, sleeve, container, or other construct.

Packaging, in particular pre-packaging, for food, comprising a side part. The side part encloses a receiving space for food, and a bottom part. The bottom part is connected to the side part. The connection between the side part and the bottom part includes, at least partially, a releasable connection. The connection between the side part and the bottom part includes, at least partially, a permanent connection. The permanent connection is at least partially movable. The at least partially movable configuration of the permanent connection allows a hinge effect between the side part and the bottom part. The bottom part can be folded down after an at least partially release of the releasable connection.
