Definitions

  • the present invention generally relates to an insulating protection box, or a protection insert for a packaging box useful for certain sensitive products.
  • sensitive products is meant, in this connection, especially shock sensitive products and products which are inclined to explode.
  • shock sensitive products and products which are inclined to explode.
  • Especially many products included in modern motor cars need very safe transport packages, for instance car crash (safety) cushions, car safety belts, car safety side cushions, side protection curtains and other products containing certain types of explosives, thermostat systems which are sensitive to too high or too low temperatures, crash sensors which are sensitive to shocks, and many other types of products.
  • the object of the invention therefore has been to solve the problem of providing a packaging box, or a box insert for certain sensitive products, which box is preferably made of a relatively thick mineral wool material or another material having equivalent properties, which material is shock damping, which has thermal insulating properties both against heat and cold, and which is capable of damping eventual accidental releasing of small explosive charges.
  • the box is made in the form of a plate or board of a relatively thick material like mineral wool or an equivalent material.
  • the thickness of the plate is to be considered in view of the demands on fire resistance, shock damping etc. which are called for in each specific case.
  • plates having a thickness of between 20 and 100 mm.
  • Such plates can not be folded without becoming broken, and therefore the plate has to be formed with grooves along which the bottom, the sides and the lid can be folded to provide an integral closed box.
  • a problem in this connection is to keep the different parts of the box in contact with each other while the box parts are being folded together.
  • Mineral wool has not sufficient tensile strength for allowing a formation of "creasing lines", what is very well possible with for instance corrugated cardboard.
  • the side of the material plate intended to form the exterior side of the ready box can be formed with a covering of a material having a high tensile strength, for instance a textile material, a foil or a suitable non-inflammable material, eventually combined with each other, whereas the other side of the plate is formed with grooves for making the folding possible.
  • a non-cured (hardened) plate is placed on a press plate having a suitable profile, the intended surface covering material or materials are placed on the mineral wool plate and the combined base material is moved into a heating press, in which the mineral wool becomes pressed and cured while grooves are pressed down into the mineral wool material, and the surface covering material or materials is/are pressed to stick to the other side of the mineral wool plate.
  • a heating press in which the mineral wool becomes pressed and cured while grooves are pressed down into the mineral wool material, and the surface covering material or materials is/are pressed to stick to the other side of the mineral wool plate.
  • the invention also relates to a method of manufacturing an insulating protection box or an insert for an insulating protection box, according to which method a box is made from a flat blank of a relatively thick insulating material having fire proof, shock damping, thermal insulating properties, and which has thereby explosion preventive properties, which blank, at the exterior side of the box to be made is formed with a shape binding/keeping material, like a metal net or a synthetic resin type material, whereupon grooves corresponding to the joints between the different box parts are milled or cut up to a depth adjacent the shape keeping material, and the different parts of the box are fold together to form a substantially sealed box.
  • the box material with the shape keeping material which may be a metal net, a synthetic resin or a corresponding material can be covered with a liquid and/or gas sealing material, like an aluminum foil or a suitable synthetic resin.
  • the grooves may be formed to provide a type of labyrinth sealing which makes it difficult for liquid, gas or air to penetrate out of or into the box.
  • figure 1 is an exploded view of a blank for a box having bottom and sides, before the shape keeping material and eventually a liquid- and gas-sealing material is applied at the exterior side of the box to be formed.
  • Figure 2 shows an intermediate method step in which grooves have been milled up or cut up grooves in the material for the corner joints to be formed.
  • Figure 3 shows a partly ready made rectangular box whereby two sides thereof have been fold up.
  • Figure 4 is a plan view of a blank for a box having bottom, sides and top.
  • Figure 5 is a fragmentary view showing a cross section through a blank for a box formed with one possible example of labyrinth corner joint parts, and figure 6 shows a ready corner provided from the blank of figure 5.
  • Figures 7 and 8 show, like in figures 5 and 6, a blank and a corner, respectively, of an alternative type of labyrinth joint.
  • Figure 9 shows a press plate having a screen for providing grooves in the mineral wool material.
  • the blank for a box shown in figure 1 can be made of a relatively thick plate or board 1 , for instance a plate of a mineral wool material having a thickness of 20-100 mm. In the illustrated case it is intended to form a parallel epipedical box, but it is obvious that the box may alternatively have a polygonal bottom section, or even that the box may have a curved or otherwise formed bottom plane.
  • a box part comprises only a bottom and sides, but it is to be understood that also a lid can be formed integral with the box blank.
  • the exterior side of the box to be formed should be provided with a shape keeping material 2, in the illustrated case sketched as a hen net or a chicken wire net, but said shape keeping material may be of any other material having form stiff properties, so that is can keep the bottom, the side pieces and the lid together when the box is fold together along given fold lines.
  • the box material can be formed with a surface layer 3 which can be a liquid or gas sealing material, for instance a suitable plastic material or an aluminum foil.
  • the blank for the box can be made in that a plate of a non-cured mineral wool material is placed, with one side thereof, against a groove forming screen pattern provided in the press, as indicated in figure 9. On the other surface there is placed a material having a high tensile strength, and thereafter the plate is pressed and cured. If found suitable a further protecting and/or decorative surface layer may thereafter be attached to the exterior surface of the box to be formed.
  • the blank of the box also can be made in that a flat blank of a relatively thick insulating material having fire proof (protecting) and shock dampening properties and which has thermal insulating properties, and which thereby has explosion protecting properties on one side of the blank, namely the exterior side of the box to be manufactured is formed with a stiffening material having strong tensile properties, like a metal wire net 2, or another material like some type of synthetic resin net, whereupon V-grooves 6 are milled or cut out at the opposite side of the blank to a depth adjacent the surface covering material.
  • corner joints 4 and 5 can be milled or cut out from the upper side of the plate or board 1 down to a depth adjacent the shape keeping material 2.
  • Said corner joints can be formed as grooves, e.g. V-grooves 6 as partially shown in figure 2, but the joints also can be formed as some type of labyrinth sealing means, as shown in figures 5-8.
  • the blank is formed to a box, as indicated in figure 3.
  • Said figure 3 shows a box having a bottom 8 and four side pieces 9, only two of side pieces 9 of which are shown fold up against the bottom 8.
  • the joints 6 may, upon need, be fixed by means of tape or glue. It is obvious that the box is substantially sealed.
  • FIG 4 is shown a blank for a box adapted to provide a closed box having a bottom 8, side pieces 9 and a lid 10. Otherwise the box blank is identical to the box blank shown in figures 1-3.
  • Figure 9 shows a way of manufacturing a box of the type shown in figure 4.
  • a press plate which is suitably profiled or is formed with a groove forming screen pattern, for instance formed as a square pattern of V- shaped metal profiles 13 on top of which the mineral wool material is placed.
  • the shape keeping material having a high tensile strength is placed, for instance the chicken wire net, whereupon the entire apparatus with the combined material is moved into a heating press in which the mineral wool is pressed and is cured, whereby the metal profiles 13 form grooves 6 on one side (the inner side) at the same time as the shape keeping material, e.g. the chicken wire net, or the synthetic resin net, is pressed into the mineral wool material on the exterior side of the box to be manufactured.
  • an additional protecting and/or decorative surface layer can be attached on top of the shape keeping material.
  • the corner joints are as liquid and gas sealed as possible, and to this end the corner joints can be formed as a type of labyrinth joints, as shown in a first example, out of many possible examples, in figures 5 and 6, and a second possible example as shown in figures 7 and 8.
  • the joint of figures 5 and 6 is formed as a three-step angle joint 11 whereby the joint surfaces are located at right angles to each other.
  • a corresponding labyrinth sealing 12 which at the lower/outer part thereof is formed with a bevelled groove joint followed by an angle joint.
