  • Patent number: 4724957
    Abstract: The invention relates to a method for producing book-like containers for tape-like or disk-like record supports for acoustic and/or optical information, as well as data processing programs, with a book back made from cardboard and a reception part fixed thereto for the record supports and a container produced by this method. From a cardboard blank is initially produced a book cover with a round back part, followed by the production of a foil-lined print covering, which is provided with a system impression and is then connected to the book cover. Then on the first inside of the book cover is fixed a cover member for the reception part formed as a deep-drawn part from polystyrene or the like and on the other inside of the book cover is fixed a base member also made as a deep-drawn part from polystyrene or the like and which is connected with the cover member of the reception part by a preshaped back part. As a result, in the vicinity of the back part, the book cover is not joined therewith.
