Definitions
- a Box Element such as a Travelling Bag or
- the present invention relates to a travelling bag or suit-case, the wall of which consists of an inner stiff tray, an outer wear-proof skin and an intermediate layer " of foamed plastics.
- Bags or cases are known, wherein a padding element of shock-absorbing and/or heat insulating material, e.g. rock-wool or cotton wadding, is glued to the inner layer of the wall prior to the application of the outer skin of plastic foil or leather, or is inserted as a pad between the layers previously welded together to form the inner and outer sides of the bag.
- a padding element of shock-absorbing and/or heat insulating material e.g. rock-wool or cotton wadding
- the inventive bag is characteristic in that the intermediate layer of foamed plastics in the wall of the bag is a hard foam which is firmly compressed during foam ⁇ ing in and complete filling of the space between the tray and the skin, so that the outer skin of the wall is kept tightly stretched by the foamed material.
- a bag is easily manufactured by the thin flexible skin being ar ⁇ ranged on the outside of the tray secured to the upper edge thereof, a foaming agent, such as polyurethan foam or a corresponding one or two-component material thereafter be ⁇ ing injected into the space between the tray and the skin in such an amount that when hardening it will stretch the outer skin and form a firmly compressed shock-absorbing padding.
- the pressure from the foamed plastic material stretches the outer skin evenly all over, and in this way • it is possible to manufacture bags which are particularly shock-absorbing and therefore very well suited, e.g. as medical bags and tool and instrument bags for transport- ation of delicate instruments.
- the upper edge of the tray and the edge portion of the skin arranged around the side walls of the tray may be connected with each other by means of a frame formed in such a way that the pressure from the compressed plastic cooperates in keeping the frame firmly connected with the upper edge of the tray and the skin firmly connected with the frame.
- the holes in the frame are easi ⁇ ly closed on the outside after the casting of the foam agent.
- a bag to be used as a medical case or as depository for instruments is easily constructed with holding means for the instruments when formed as stated in the character ⁇ izing clause of claim 4.
- the bag or case according to the invention may furthermore be adapted, in a cheap and effective manner, as a burglary-secured case for transportation of banknotes, securities, coins or other articles of value.
- a mesh of metal wire may be cast in the layer of foamed plastics surrounding the interior of the case, so that it would be very difficult or impossible to cut through the case with a knife or saw.
- such a mesh may constitute a cheap element of a system which in case of attempts at breaking the case open will eject a liquid which makes articles of value, e.g. banknotes, kept
- the drawing shows a section through part of an em- • bodiment of the bag or case according to the invention.
- the bag or case as usually consists of a bottom portion and a cover portion or of two identical halves hinged to each other.
- the interior space of .each half is defined by a stiff box-shaped tray of hard plastic or possibly of metal.
- the tray 1 constitutes the inner layer of the wall of the case which on the outside is covered with a skin 2 of flexible tensile material, ' such as plastic foil or leather. Between the inner layer 1 and the outer layer 2 of the wall firmly compressed hard foamed plast ⁇ ics 3 is cast by foaming in situ.
- the foamed plastics have a shock-absorbing and heat-insulating effect and keeps the layer 2 forming the skin of the case, tightly and smoothly stretched.
- the upper edge of the tray 1 and the skin 2 are connected to each other by a frame 5, and the pressure from the foamed plastics 3 cooperates in keeping the inner layer 1 as well as the outer layer .2 in firm connection with the frame 5.
- the bag or case according to the invention is easi ⁇ ly manufactured by arranging the skin 2 around the lower portion of the tray 1, the edge portion of the skin 2 be ⁇ ing secured to the lower portion 10 of the mounting 5, e.g. by glueing or nailing, and the upper edge of the tray 1 be ⁇ ing secured to the mounting 5 in any suitable manner, e.g.
- the tray 1 with the surrounding skin 2 is placed in a mould 4, in the draw ⁇ ing indicated by dotted lines, and a two-component foaming material 3 is injected through holes in the skin 2, the tray 1 or the frame 5.
- foaming the material the flex ⁇ ible skin 2 is pressed tightly and smoothly against the inner side of the mould 4.
- the appearing outer contour of the bag or case is maintained when the foamed plastics hav hardened as a firm shock-absorbing and insulating sub ⁇ stance.
- the pressure in the_ foamed plastics 3 moreover co ⁇ operates in keeping the skin 2 firmly against the frame portion 10, in keeping this portion 10 and the remaining portion of the frame 5 together, and in keeping the frame 5 in firm connection with the tray 1.
- Through-going holes 6 in the frame 5 may further contribute to retain the frame on the bag by means of the deadheads formed at the holes.
- the holes 6 and other casting and overflow holes if any, are closed on the outside after the casting.
- Mountings 1 to hold tools or instruments are. securely maintained in position by discs 8 screwed on the outer side of the tray 1, said discs being pressed firmly against the tray by the foamed plastics 3.
- a fine-meshed network 9 of metal wire is embedded in the foamed plastics 3 to pre ⁇ vent cutting in the wall of the case and, as referred to, may be connected to an electric ignition mechanism act- ivating a system which makes the contents of the bag or case worthless at attempts to break the bag open.

Abstract
Une valise ou un élément semblable à une boîte possède une paroi isolante et d'amortissement des chocs comprenant un plateau interne (1) relié par l'intermédiaire d'un cadre (5) à une pellicule externe (2), et un matériau en mousse plastique est injecté dans l'espace délimité entre le plateau et la pellicule de telle manière qu'après moussage une couche isolante et d'amortissement (3) se forme. Un réseau (9) peut être noyé dans la couche de plastique mousse (3), et des éléments de fixation (7) d'outils ou instruments peuvent être fixés à l'aide de disques (8) vissés sur des tiges des éléments de fixation et comprimés contre le plateau (1) par la pression du matériau mousse. En outre, le matériau en plastique mousse contribue à ce que le plateau (1), le cadre (5) et la pellicule (2) restent assemblés et à ce que la pellicule externe (2) garde un aspect tendu et lisse.A suitcase or a box-like element has an insulating and shock absorbing wall comprising an internal plate (1) connected by means of a frame (5) to an external film (2), and a material made of it. plastic foam is injected into the space delimited between the plate and the film in such a way that after foaming an insulating and damping layer (3) is formed. A network (9) can be embedded in the layer of foam plastic (3), and fastening elements (7) of tools or instruments can be fixed using discs (8) screwed on rods of the fixation and tablets against the plate (1) by the pressure of the foam material. In addition, the foam plastic material contributes to the fact that the tray (1), the frame (5) and the film (2) remain assembled and that the external film (2) keeps a taut and smooth appearance.
