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 bag-like container includes a bottom sheet including a first paper base layer and a heating element layer configured to generate heat by absorbing electromagnetic waves; and a top sheet bonded to the bottom sheet in such a manner as to be separable from the bottom sheet with a content to be cooked being contained, wherein the top sheet transmits the electromagnetic waves.

A microwave heating construct comprises a base, a wall extending upwardly around the base for defining a cavity for receiving a food item, and a microwave energy shielding element overlying a lower margin of the wall, the microwave energy shielding element having an upper edge including a substantially incurved portion.

A microwave packaging material for forming a construct for holding a food item. The microwave packaging material can include a film at least partially secured to a substrate by a pattern of adhesive. A plurality of closed cells can extend between the film and the substrate, each closed cell of the plurality of closed cells can be at least partially defined by the pattern of adhesive, and each of the closed cells can be configured to expand during heating to form respective expanded cells. The microwave packaging material further can include a bonded region extending along at least a portion of the microwave packaging material. The film can be secured to the substrate along the bonded region, and the bonded region can be for forming at least one recess among the expanded cells and can be for extending along the food item when the microwave packaging material is heated.

The present invention relates to a susceptor combination comprising: metallic particles; particles of at least two or more semiconductor materials; and one or more alkaline or alkaline earth metal salts; to a susceptor ink composition containing it. It also relates to a laminate comprising a dielectric substrate and the susceptor ink composition printed on the substrate, as well as a microwaveable package comprising the laminate.

A container for holding a food product. The container can comprise a flange comprising a central panel. An opening can extend in the central panel. The container further can comprise a sidewall comprising at least a panel foldably connected to the central panel and a denesting feature extending outwardly from the sidewall. The denesting feature can be for engaging a nested container positioned below the container in a stacked arrangement and for forming a denesting gap between the flange and the nested container.

A container for holding a food product. The container can comprise a base layer and a liner at least partially attached to an inner surface of the base layer, a flange comprising a central panel of the base layer, an opening extending in the central panel, and a sidewall comprising at least a panel foldably connected to the central panel along the opening.

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.

Microwave cooking packages suitable for use as microwave popcorn packages include at least one panel (e.g., first and second panels) formed of a vertically rigid material. A flexible portion is attached to the panels. The flexible portion may be formed of a polyester film material such as a biaxially-oriented polyethylene terephthalate (PET) film, which may be at least partially transparent. The flexible portion (and panels) defines a bag construction configured to contain a popcorn charge and to be expandable between a collapsed configuration and an expanded configuration when the popcorn charge is subjected to a popping operation. The microwave cooking package may include a vent assembly configured to at least partially open when the bag configuration is in an expanded configuration to vent the bag construction. The vent assembly includes a first portion a second portion of the bag construction that is configured to be folded against the first portion.

A flexible microwave heating package for food includes a first panel and a second panel joined to one another in a facing relationship, and a third panel joined to the first panel and the second panel. The first panel and second panel define walls of the package and the third panel defines a base of the package. The first panel and second panel may each include microwave energy interactive material operative for reflecting at least a portion of incident microwave energy.
