A BOX ELEMENT SUCH AS A TRAVELLING BAG OR SUIT-CASE

摘要

A suit-case or a similar box-element has a shock-absorbing and insulating wall comprising an inner tray (1) connected through a frame (5) to an outer skin (2), and foamed plastics are injected in the space between the tray and the skin in such a manner that after foaming it forms a hard shock-absorbing and insulating layer (3). A network (9) may be embedded in the layer of foamed plastics (3), and mountings (7) for tools or instruments can be secured in position by means of discs (8) screwed on shafts of the mountings and pressed against the tray (1) by the pressure in the foamed material. Further, the foamed plastics assist in keeping tray (1), frame (5) and skin (2) together and in maintaining a tight and smooth outer skin (2).
