Abstract:
A susceptor includes an absorbent substrate layer (50); a first susceptor layer (30) including microwave susceptor material over the substrate layer; and a first protective (40) overcoating layer over the first susceptor layer, where the absorbent substrate layer comprises non-woven fibers.
Abstract:
A tray (100) or container (478) which may be hermetically sealed having a flange encapsulated by or formed from injection-mold material. The tray (100) has a flange (116) extending outwardly from a sidewall (114) of the tray, and containing irregularities induced by the creation of the tray (100). An encapsulating material surrounds the flange (116) in substantially uniformly thick manner, and along with the flange (116) defines an encapsulated rim (124). The encapsulating material is generally a plastic such as polyolefin, nylon, or polyethylene, but may also be made from other materials. This encapsulating material covers a portion of the flange (116) and extends a set distance from the flange's (116) outer edge.
Abstract:
An abuse-tolerant microwave food packaging material (200) includes an array (215) of solid shapes (208) of microwave energy reflective material, for example, of aluminum foil, disposed on a substrate (214). The array (215) of shapes (208) of microwave energy reflective material shield microwave energy from a food product while remaining substantially resistant to arcing or burning under abusive cooking conditions in a operating microwave oven.
Abstract:
A microwave container (10) which morphs from a relatively microwave transparent condition to a relatively microwave blocking condition in response to microwave irradiation. The container wall section has a plurality of discrete, unconnected microwave reflective material elements (20) initially permitting the transmission of microwave energy into the container (10) and either a microwave absorptive material (22) or a thermally responsive material active to coalesce the microwave reflective material elements (20) into a connected array or pattern to block the transmission of microwave energy from entering the container (10) after absorbing a predetermined amount of microwave energy.
Abstract:
A thermocompensating susceptor (52) is described comprising a microwave transparent sheet (54), e.g. paper, paperboard or plastic, having a layer (56) thereon of a dried dispersion comprising a film forming vehicle together with two kinds of dispersed particles including microwave interactive particles such as a metal, metal oxide, carbon or graphite that absorbs microwave energy to produce heat in a microwave oven and electrically nonconductive thermocompensating particles of a mineral hydrate containing bound water of crystallization and having a dissociation temperature between about 100 °F and 500 °F, at which temperature the bound water is released therefrom to prevent overheating of the laminate.
Abstract:
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.
Abstract:
Packaging material includes microwave interactive material and is automatically reconfigurable for selectively controlling transmission of microwave energy through the packaging material. The packaging material is configured to vary, as a function of time, a ratio of microwave energy transmitted through the packaging material. The packaging material is configured so that the microwave energy is automatically selectively transmitted in different ratios.
Abstract:
A tray for heating, browning, and/or crisping a food item in a microwave oven comprises a substantially planar base, a platform extending upwardly from the base, and a microwave energy interactive element overlying at least a portion of the platform.
Abstract:
A construct for heating a food item in a microwave oven comprises a base (102), a wall (104) extending upwardly from the base (102), a microwave energy shielding element (108) overlying at least a portion of the wall (104), and a microwave energy diffusing element (112) circumscribed by the microwave energy shielding element (108), where the microwave energy diffusing element (112) includes a plurality of microwave energy reflective elements (116) within a microwave energy transparent area (114).
Abstract:
A microwave heating package (100) comprises a dimensionally stable first component (102) for supporting a food item and a flexible second component (104) dimensioned to receive the dimensionally stable first component. Each of the first component and the second component may include a microwave energy interactive element (106, 124) for altering the effect of microwave energy on a food item within the package.
