Packaging having field modifiers for improved microwave heating of cone-shaped products

(canceled)

A unitary blank for making a packaging having field modifiers for improved microwave heating of cone-shaped products, said unitary blank comprising a substrate made of a microwave inert material defining a plurality of wall panels connected to each other by score lines which can be folded to form a box-shaped container configured to contain a filled dough-based cone-shaped product, and a plurality of shielding patches made of a microwave shielding material arranged on selected inner areas of said wall panels, wherein said microwave inert material of said substrate is selected from a group comprising paperboard material and plastic material, and wherein said shielding patches comprise:

• a first set of shielding patches located on said wall panels to be positioned around a lower cone tip region of said filled dough-based cone-shaped product when the unitary blank is folded into said box-shaped container and configured to shield said lower cone tip region;
• and
• a second set of shielding patches located on the wall panels to be positioned around an upper cone rim region of the filled dough-based cone-shaped product when the unitary blank is folded into the box-shaped container and configured to shield said upper cone rim region and enhance the heating of an exposed central top region of a filling of the filled dough-based cone-shaped product.
