Abstract

A swing door system for use with a freezer device is provided. The system includes two adjacent swing doors and a mullion in contact with the swing doors. Each swing door has a transparent pane and a non-transparent area. The non-transparent area is proximal to the mullion when the swing doors are in a closed position. The non-transparent areas and the mullion define a non-transparent region. The system has, under a horizontal viewing angle between 0° and 180° with respect to the plane in which the swing doors are arranged when the swing doors are in the closed position, all of the horizontal diameters of the non-transparent region are less than 100 mm.
