A sealed oxygen-tight cooking device for food comprising a first layer (6) with means for preventing inflation by warm moist air during cooking, a second layer impervious to grease and liquid from the food, a fat-absorbing support layer (1) between the first layer and the second layer, wherein the fat-absorbing support layer (1) has openings (3) there through, said fat-absorbing support layer is adapted to support a food thereon, and the food (5) placed on the fat-absorbing support layer (1), wherein the first layer, the second layer and the fat-absorbing support layer are made from materials suitable for use in an oven.

A process and apparatus for heating a microwave transparent material or di-polar material. The apparatus includes a vessel that has susceptor material on at least a portion of the vessel walls. Microwaves are generated by a microwave transmitter and introduced into the vessel which can heat both microwave transparent materials and di-polar materials within the vessel.

A frozen food product according to the present application comprises: a frozen food; a food container having formed therein an inner space for accommodating the frozen food and formed of an edible material; and a packaging material including a first packaging material surrounding the frozen food and disposed between the food container and the frozen food, and a second packaging material surrounding the food container, in order to prevent moisture from being transferred to the food container, wherein the packaging material generates heat by means of microwaves.

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.

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 structure for sealing and keeping food fresh, which can be repacked after unpacking. The container structure has a container body and a covering film; the container body has a housing chamber, a first abutting face, a concave groove portion, a second abutting face and a preset break line; the covering film can seal the housing chamber and bond with the first and second abutting face, specifically, it is bonded to the first abutting face through the micro sealing portion, so that the bonding between the covering film and the first abutting face is weaker than the bonding between the second abutting face; To open the covering film, the user needs to apply a force upon the external edge of the top end of the container body, to break the preset break line, and to separate the covering film from the first abutting face, so as to form a separated and independent frame.

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 method of forming a container from a blank. The method can comprise obtaining a blank having a wall portion, a flange portion, and a coating on at least a portion of the flange portion. At least one score line can extend at least partially in the flange portion, and the coating can at least partially cover the at least one score line. The method further can comprise forming the container from the blank by forming a wall of the container from the wall portion and forming a flange of the container from the flange portion. The flange can extend from the wall. The forming the container further can comprise forming the at least one score line into at least one pleat in at least the flange. The coating can at least partially cover the at least one pleat to form a substantially continuous sealing surface on the flange.

An outer portion of one or more layers of microwave interactive material, which is for becoming hot when exposed to microwave energy, is arranged in a manner that seeks to advantageously control heating, so that the outer portion of the microwave interactive material can safely be adjacent the periphery of a turntable tray. The turntable tray can be heated by the microwave interactive material so that a peak thermally induced stress occurs in the turntable tray at a position proximate the periphery of the tray. The layer(s) of microwave interactive material are configured in a manner so that the peak thermally induced stress is less than a predetermined amount.

A microwave packaging material for forming a construct for holding a food item. The microwave packaging material can comprise 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 comprise 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.
