  • Patent number: 3938688
    Abstract: A tray assembly for the delivery and service of foods, such assembly including base and cover sections having a plurality of opposing recesses for enclosing a number of dishes, cups, and other utensils needed for a complete meal service. Proper vertical alignment of the two sections as they are fitted together is facilitated by corresponding lateral indentations in the side walls of both parts which serve in manual guiding of the cover into position upon the base, and by arcuate shoulders spaced circumferentially about a generally central recess in one of the sections, such shoulders being received in a complementary channel in the other section. Lugs disposed within the channel are received in notches between the arcuate shoulders only when the cover and base sections are in precise rotational alignment.
