Document Type and Number:
WIPO Patent Application WO/2002/076847
Kind Code:
A1
Abstract:
Insulating protection box, or a protection insert for certain sensitive product, like shock sensitive products, temperatures sensitive products and products inclined to explode, and made of a relatively thick, flat base material plate (1) of mineral wool or an equivalent material which at the exterior side thereof is provided with a shape keeping material (2), like a hen wire net, which is slightly pressed into the base material, which has thereafter been cured, and which at the opposite side of the base material is formed with corner recesses (6), and in which the box is manufactured by folding up side pieces (9) against the bottom (8) and the corner joints (6) are interconnected. At the exterior side the box blank may have a surface covering exteriorly of the shape keeping material (2), which surface covering may be a foil (3) of aluminum or some suitable plastic material.

CLAIMS
| 1. | Insulating protection box, or a protection insert for a packaging box to be used for certain sensitive product, like shock sensitive products, temperatures sensitive products and products inclined to explode, and made of a relatively thick base material of mineral wool or another material having equivalent properties, and in which the box is made starting with a flat plate (1) of mineral wool or an equivalent material type, which at one side thereof is formed with corner recesses (6), and in which the box is manufactured by folding up the side pieces (9) against the bottom (8) and the corner joints (6) are interconnected to form a closed integral unit, characterized in that the insulating protection box is exteriorly provided with a shape keeping material (2) having a high tensile strength and which is preferably slightly pressed into the base material, which has thereafter been cured (hardened). |
| 2. | Box according to claim 1, characterized in that the shape keeping material is a metal net, for instance a hen wire net or a chicken wire net (2), which is pressed a slight distance into the base material (1), and which is secured therein in that the base material, which contains certain resins, has been heat cured. |
| 3. | Box according to claim 1 or 2, characterized in that the base material (1) at the exterior side of the box to be made, exteriorly of the shape keeping material (2) is covered with a decorative, liquid tight or gas tight covering (3) of a plastic material, an aluminum foil or an equivalent material. |
| 4. | Box according to any of the preceding claims, characterized in that the corner recesses are formed as Vgrooves (6) or some type of labyrinth grooves (11 ; 12). |
| 5. | Box according to claim 4, characterized in that the corner joints (6; 11; 12) of the box are secured by means of tape or glue. |
| 6. | Box according to any of the preceding claims, characterized in that the base material of the box, after having been pressed and cured, has a thickness of between 20 and 100 mm. |
| 7. | A method of manufacturing an insulating protection box, or a protection insert for a packaging box useful for certain sensitive products, like shock sensitive products, temperature sensitive products and products which are inclined to explode, and made of a relatively thick base material of mineral wool or another material having equivalent properties, characterized in that a box is made from a flat blank (1) of a relatively thick base material like mineral wool or a material having equivalent properties, in that the blank (1), at the exterior side of the box to be made, is formed with a shape keeping material (2), for instance a metal net, in that the shape keeping material (2) is pressed a slight distance into the base material (1), in that the base material with the shape keeping (2) is pressed and is heat cured, and in that grooves (4,5) for the joints (6) between the different box parts (810) are pressed into or cut out of the base material (1) to a depth close to the shape keeping material (2), and that the different parts (810) of the box are fold together thereby forming a substantially sealed box. |
| 8. | A method according to claim 7, characterized in that a metal net, for instance a hen wire net or a chicken wire net (2) is used as a shape keeping material, and in that a decorative liquid and gas tight material (3), like an aluminum foil or a suitable plastic material is connected by tape or glue outside of the shape keeping material (2), and whereby grooves (4,5) for the joints (6) are pressed into the base material using a screen (13) of a press plats, at the same time as the shape keeping material (2) is pressed into the opposite side of the base material, whereupon the entire objects is pressed and is cured. |
| 9. | A method according to claim 7 or 8, characterized in that the grooves (4,5) for the joints between the different box parts (810) are substantially V shaped grooves (6) or some type of labyrinth grooves (11; 12). |
