ABSTRACT:
A packaging holder for protecting and positioning internal elements, such as a glass tray and a rotating ring in the cooking cavity, of a packaged microwave oven is disclosed. The holder has a side holder part, a bottom seat part and a retaining flap part. In the holder, the diametrically-opposite side portions of the glass tray are inserted in and held by the side holder part. The bottom of the tray is held on the bottom seat part, while the top of the tray is covered with the retaining flap part. The rollers of the rotating ring are held by the roller holding notches of the retaining flap parts. The above holder is diagonally placed inside the oven's cavity in a way such that the holder is brought into close contact with the diagonally-opposite corners of the oven's cavity. The holder is made of a corrugated cardboard, so that the holder can be recycled while not causing environmental pollution.
