  • Patent number: 4106597
    Abstract: A food carrying, attache' case contains a removable insert in which food, papers and documents are transported. The insert is a block of thermally insulating foam formed with cavities which matingly receive food and beverage containers and utensils. A covering lid is hinged to the foam block and has a layer of resilient, insulating foam bonded to its underside so that closing of the lid compressibly retains the food containers in the cavities. The top of the lid is sufficiently smooth and flat to form a writing work surface. A pressure sensitive latching means is provided for at times holding the lid closed and at times fastening the lid to the opened part of the attache' case to hold the lid open during use.
