  • Patent number: 4555794
    Abstract: An X-ray film holder is disclosed comprising a bottom (1) to receive both the X-ray film (6) and image intensifying screens (7, 8) placed against the film, and a lid (2) to close the holder. The bottom (1) and the lid (2) are provided on all sides with grooves (3) and projections (4) that fit into one another so that the lid (2) can slide with respect to the bottom (1) by means of the guide system thus formed, and is interlocked with the bottom (1) on all sides when in the closed position. A foam cushion (10), placed within a cover (9) made of airtight material, which extends roughly over the entire film surface, is connected to the lid (2) by means of the wall of the cover. The cover (9) and the lid (2) are provided with interconnecting openings (11, 12) for the evacuation of the interior of the cover. The holder can therefore be opened after it is evacuated.
