Patent number: 7319213Abstract: Indentation patterns in microwave packaging materials can enhance the baking and browning effects of the microwave packaging materials on food. The indentation patterns can provide venting to either channel moisture from one area of the food product to another, trap moisture in a certain area to prevent it from escaping, or channel the moisture completely away from the food product. The indentation patterns can cause the microwave packaging material underneath a food product to be slightly elevated above the cooking platform in the base of a microwave. The indentation patterns can lessen the heat sinking effect of the cooking platform by providing an air gap for insulation. Elevating the base of the microwave packaging material further allows more incident microwave radiation to propagate underneath the microwave packaging material to be absorbed by the food product or by microwave interactive materials in the microwave packaging material that augment the heating process.Type: GrantFiled: July 15, 2005Date of Patent: January 15, 2008Assignee: Graphic Packaging International, Inc.Inventors: Sandra M. Tsontzidis, Laurence M. C. Lai, Neilson Zeng

Patent number: 6717121Abstract: A container has a patterned susceptor region in the bottom, a fold region between the bottom and the sidewall of the container, a sidewall region, and a flange region that forms a flange or lip of the container. The patterned susceptor region includes arrangements of microwave-interactive features disposed generally along respective close plane curves, which reduces overheating and increases the filling temperature of the food product. The fold region contains microwave transparent features that minimize de-lamination of the container in the folded region, and also create a generally transmissive area in the vicinity of the heel of the food product to improve the cooking thereof. The sidewall region shields the periphery of the food product so that it is not overcooked while promoting an appropriate degree of pie dough shell browning. The flange area is transmissive to promote an appropriate degree of cooking of the food product crust.Type: GrantFiled: December 21, 2001Date of Patent: April 6, 2004Assignee: Graphic Packaging International, Inc.Inventors: Neilson Zeng, Laurence M.

Patent number: 6251451Abstract: The disclosed invention provides a microwavable package for a food product. The package comprises a base with an active microwave energy heating element to support the food product. The active microwave heating element comprises energy collecting resonant loops, tuned structures, and transmission lines to collect incident microwave energy and redirect it to other parts of the food product. The microwave package also includes a cover comprising a microwave energy interactive layer including one or more apertures within the cover. The apertures promote localized fields to promote browning of the food product in the local areas around the apertures. The cover may also comprise a susceptor layer that is heated in localized areas around the apertures due to the fields promoted by the apertures and impingement by incident microwaves energy through the apertures, thereby providing localized browning of the food product.Type: GrantFiled: May 26, 1999Date of Patent: June 26, 2001Assignee: Graphic Packaging CorporationInventor: Neilson Zeng

Patent number: 6150646Abstract: A microwavable container includes an outer sleeve (12) and an inner tray (14) within the sleeve designed to carry a food product. A first active microwave energy heating element (28) is on the sleeve and disposed opposite the tray. A second active microwave energy heating element (74-102) is within the tray. The second microwave energy heating element has patterns of microwave energy interactive material on the bottom (60) and side walls (62) of the tray configured to permit a controlled degree of penetration of incident microwave energy through the bottom wall to channel microwave energy towards a central region of the tray and to promote browning of a food product carried by the tray about its periphery.Type: GrantFiled: June 24, 1999Date of Patent: November 21, 2000Assignee: Graphic Packaging CorporationInventors: Laurence Lai, Neilson Zeng

Patent number: 6133560Abstract: A patterned susceptor structure has a relatively thin electroconductive material for converting incident microwave energy to thermal energy. The patterned susceptor has a lobe shaped island strip nested within and surrounded by an outer strip. The island strip is coupled to the outer strip to stimulate uniform heating between an outer edge of the susceptor structure and a center portion of the susceptor structure. The island strip is coupled to the outer stip by spacing the island strip from the outer strip with a microwave-transparent slotline.Type: GrantFiled: October 9, 1998Date of Patent: October 17, 2000Assignee: Fort James CorporationInventors: Neilson Zeng, Igor Kotlarenko

Patent number: 6114679Abstract: A microwave energy heating element has a plurality of spaced microwave components generally arranged in a closed loop pattern. Each of the microwave components (42, 44) has a non-resonant length. When the heating element is in a loaded condition with a load juxtaposed thereto for capacitively coupling the microwave components together, the microwave components cooperatively redistribute impinging microwave energy. When the heating element is in an unloaded condition, the microwave components act independently remaining inert to impinging microwave energy.Type: GrantFiled: September 29, 1998Date of Patent: September 5, 2000Assignee: Graphic Packaging CorporationInventors: Lawrence Lai, Neilson Zeng
