Abstract

A device for destroying dangerous objects such as shells, munitions or other charges that are to be destroyed by detonating them, which device includes a packaging produced from a flat blank folded on itself along three folds, four folds or more in order to form at least three sides and two half, four sides or four sides and a flap for closing the packaging which is produced in the form of a tubular package of polygonal and notably square or rectangular cross section once the flat blank has been folded up, with explosive charges placed on the sides that are to be folded, the flat blank being of dimensions suited to being able to house, in the middle of the tubular package in contact with the explosive charges, one or more of the dangerous objects that are to be destroyed.

First claim

What is claimed is:

1. A device that is configured to destroy objects by detonating said objects, the device comprising:
a packaging produced from a flat blank that is configured to be folded on itself along at least three fold lines to form one of (a) at least three sides and two half-sides, (b) four sides or (c) four sides and a flap that is configured to close the packaging, the packaging, in a folded state, having a tubular shape with a polygonal cross-section that is configured to receive explosive charges, which are placed on one of the at least three sides and the two half-side or the four sides that are folded, said flat blank having dimensions suited to house, in a middle of the packaging in contact with the explosive charges, at least one of said objects that are to be destroyed.

2. The device that is configured to destroy objects as claimed in claim 1 , further comprising support plates that are secured to one of the at least three sides and the two half-side or the four sides and are arranged between the explosive charges and said one of the at least three sides or the four sides in the folded state, the support plates having a width such that portions of the at least three sides and the two half-side or the four sides are foldable.

3. The device that is configured to destroy objects as claimed in claim 2 , wherein the support plates are comprised of flexible polymer foam.

4. The device that is configured to destroy objects as claimed in claim 3 , wherein the support plates have a thickness that is adaptable to a diameter of the explosive charges and a diameter of the object to be destroyed so as to maintain contact with the explosive charges and the objects to be destroyed.

5. The device that is configured to destroy objects as claimed in claim 1 , wherein the flat blank is a flat foam blank that is made of a polymer foam having pre-cut folds.

6. The device that is configured to destroy objects as claimed in claim 1 , wherein the flat blank is comprised of a flat cardboard blank having folding lines.

7. The device that is configured to destroy objects as claimed in claim 3 , wherein the polymer foam is a polyurethane foam.

8. The device that is configured to destroy objects as claimed in claim 1 , further comprising means of fixing the explosive charges to at least the at least three sides of the packaging.

9. The device that is configured to destroy objects as claimed in claim 1 , further comprising holding straps that are fixable to the packaging.

10. The device that is configured to destroy objects as claimed in claim in 1 , further comprising an ignition line that is configured to ignite the explosive charges.

11. A method of producing a package for destroying objects by detonating said objects, the method comprising:
laying flat a flat blank that is configured to be folded on itself along at least three fold lines to form one of (a) at least three sides and two half-sides, (b) four sides or (c) four sides and a flap such that the packaging, in a folded state, has a tubular shape with a polygonal cross-section;
placing at least one explosive charge on one of the at least the at least three and two half sides or the four sides;
placing an object which is to be destroyed on one of one of the at least three sides, one of the two half sides or one of the four sides;
placing an ignition line in contact with at least one of the at least one explosive charge; and
folding the flat blank so that the object to be destroyed is surrounded by the at least one explosive charge.

12. The method of producing a package for destroying objects as claimed in claim 11 , further comprising the step of positioning flexible foam plates on the at least three sides and two half side or the four sides of the flat blank prior to placement of the explosive charges and then placing the explosive charges on the plates.

13. The method of producing a package for destroying objects as claimed in claim 11 , wherein the flat blank is made of foam and includes pre-cut folds and slits to receive stowage straps.

14. The method of producing a package for destroying objects as claimed in claim 13 , further comprising the step of securing the explosive charges to the at least three sides and two half side or the four sides by the stowage straps.

15. The method of producing a package for destroying objects as claimed in claim 11 , further comprising the steps of providing holding straps that are attached to the package, attaching the package to a cargo handling apparatus by the holding straps, placing the package by the holding straps in a detonation chamber, and then detonating the package by the ignition line.

16. The device for destroying objects as claimed in claim 1 , wherein the packaging, in a folded state, has a tubular shape with one of a square and rectangular cross-section.
