A packaging structure for a cooking device is so configured that a packaging material (101) with trays (91, 92) packaged therewith is disposed in a heating chamber (2) with such an inclination that a one-side portion of the packaging material (101) becomes higher than the other-side portion of the packaging material (101). Also, the one-side portion of the packaging material (101) is placed on a one-side-portion side tray holder (16A). Further, a cushioning material (201) is inserted between an upper portion (2e) of the heating chamber (2) and the one-side portion of the packaging material (101), so that the one-side portion of the packaging material (101) is pressed against the one-side-portion side tray holder (16A) while the other-side portion of the packaging material (101) is pressed against the other-side-portion side inner side surface (2c) of the chamber.

A shipping carton having a force receiving area located adjacent opposing edges of the carton's top and bottom edges. The force receiving area is configured to deform in the presence of an external force and distribute that force through the force receiving area while minimizing the transfer of force directly to the appliance and minimizing damage to the surface panels of the shipping carton.
