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 frame is injection molded onto a group of panels to form a container. The panels extend at least partially around, and at least partially define, a cavity of the container.

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 construct for heating a food item in a microwave oven includes a base, a wall extending upwardly from the base, a microwave energy shielding element overlying at least a portion of the wall, and a microwave energy diffusing element circumscribed by the microwave energy shielding element. The microwave energy diffusing element includes a plurality of microwave energy reflective elements within a microwave energy transparent area.

A container that includes a microwave interactive web at least partially overlying and joined to a three-dimensional support, wherein the three-dimensional support may be formed prior to having the microwave interactive web mounted thereto. The three-dimensional support may be a preformed container that is sufficiently rigid and dimensionally stable for use in containing food.

Provided are a rotating structure and a container using the rotating structure, the rotating structure including: a pouch coupled to a container while being wounded around a circumference of the container; and a raw material provided inside the pouch, wherein the raw material expands the pouch by being sublimated or evaporated while being heated, and the container is rotated according to expansion of the pouch, wherein the container using the rotating structure couples the rotating structure to the container storing content therein and having a container shape.

The present invention relates to a vessel having an area for holding at least one food item for being heated in a solid state microwave oven. Additionally, disclosed is a method for heating a food item in a solid state microwave oven. Particularly, the vessel comprises a tray having an area for holding at least one food item and a susceptor wherein there is a thermal insulation between the susceptor and the food item. The tray may include two- or multi-compartment configurations wherein the susceptor only spans at least along a portion of one compartment to heat various food item simultaneously within a solid state microwave oven.

Processes and systems that enhance the heating of packaged foodstuffs and other items in various microwave heating systems are described herein. The foodstuffs may be contained in a package including one or more energy control elements that interact with microwave energy in order to alter the effect that microwave energy has on the foodstuff. These energy control elements can enhance or inhibit microwave energy and a single package may include one or more energy control elements. In some cases, the energy control element may respond differently to different types of microwave energy. As a result, some packages described herein may exhibit different absorption or reflectance characteristics when exposed to microwave energy while being pasteurized or sterilized in a larger-scale microwave heating system than when the package is reheated in an at-home microwave oven prior to consumption or use.
