Abstract

Containers and enclosing devices such as pipes or tires can be protected from explosive shocks and blasts by incorporating blast mitigating material in at least one of the top and bottom sides of a container, or by wrapping or lining the enclosing device with a blast mitigating material.

Claims

1. A container for mitigating explosions comprising a top, a bottom, and side, and wherein at least one of the top, the bottom, or the side is completely or partially lined with a blast mitigating material and an optional material anti-ballistic material.

3. The container according to claim 1 wherein the shock attenuating material is perlite.

4. The container according to claim 3 wherein the perlite is in powder form.

5. The container according to claim 1 wherein the shock attenuating material is a mixture of perlite and a fusible fireproofing salt.

6. The container according to claim 5 wherein the salt is boric acid.

7. The container according to claim 6 wherein the perlite is in powder form.

8. The container according to claim 1 wherein the container is a trash receptacle.

9. The container according to claim 1 wherein the container is a mailbox.

10. The container according to claim 1 wherein the top of the container is a removable lid, and the lid is completely or partially lined with a blast mitigating material and an optional anti-ballistic material.

11. The container according to claim 1 wherein the top of the container is completely or partially lined with a blast mitigating material and an optional anti-ballistic material.

15. The container according to claim 1 wherein the top of the container is completely or partially lined with a blast mitigating material and an optional anti-ballistic material.

2. The container according to claim 2 wherein the blast mitigating material is in the form of an assembly of two flexible sheets arranged one over the other and joined by a plurality of seams, the seams being arranged so as to form cells or recesses in the space between the sheets, and wherein the cells or recesses are filled with a shock attenuating material.

12. The container according to claim 2 wherein the top of the container is a removable lid, and the lid is completely or partially lined with a blast mitigating material and an optional anti-ballistic material.

13. The container according to claim 12 wherein the blast mitigating material is perlite.

14. The container according to claim 13 wherein the blast mitigating material is a mixture of perlite and a fusible fireproofing salt.

16. The container according to claim 14 wherein the blast mitigating material is perlite.

17. The container according to claim 16 wherein the blast mitigating material is a mixture of perlite and a fusible salt.

18. An enclosing device for mitigating explosions comprising an enclosing device wrapped or lined, completely or partially, with a blast mitigating material and an optional anti-ballistic material.

19. The enclosing device according to claim 18 wherein the blast mitigating material is in the form of an assembly of two flexible sheets arranged one over the other and joined by a plurality of seams, the seams being arranged so as to form cells or recesses in the space between the sheets, and wherein the cells or recesses are filled with a shock attenuating material.

20. The enclosing device according to claim 18 wherein the enclosing device is a pipe which is wrapped partially or completely with a blast mitigating material.

21. The enclosing device according to claim 18 wherein the enclosing device is a tire which is lined partially or completely with a blast mitigating material.

22. The enclosing device according to claim 18 wherein the best mitigating material is perlite.

23. The enclosing device according to claim 18 wherein the blast mitigating material is a mixture of perlite and boric acid.

24. The enclosing device according to claim 18 wherein the perlite is in powder form.
