Abstract

An explosive threat mitigation unit (TMU) stands ready to receive a suspected bomb, enclose it, and contain the explosion if one occurs. An operator protects bystanders and surroundings by putting the suspected bomb in a TMU and then closing the TMU. If the bomb goes off, the TMU mitigates the effects of both the blast and the fragments. One variation has a container, a tube, a cap, and a door. The container includes an opening. The tube, arranged in the container, aligns with the opening. The cap slides through the opening and over the tube. The door slides into place to close the opening and enclose the cap within the container.

First claim

What is claimed is:

1. A device comprising:
a container including an opening;
a tube disposed in the container and aligned with the opening;
a cap configured to slidably interface with the tube through the opening to form an interior closed compartment; and
a door configured to slidably close the opening to enclose the cap within the container;
the container being a one-piece, three-dimensional structure;
the container formed from integrally woven, continuous fibers;
the container further comprising a foldable region connecting a front wall to the container;
the front wall comprising a door flap;
the door flap comprising overhangs; and
the overhangs of the door flap being stitched to a top wall of the container and side walls of the container to enclose the container.

2. The device of claim 1 , wherein the container includes a plurality of wraps disposed around the container.

3. The device of claim 2 , wherein the plurality of wraps comprises a plurality of side-to-side wraps aligned along a first plane, a plurality of vertical front-to-back wraps aligned along a second plane perpendicular to the first plane, and a plurality of horizontal front-to-back wraps aligned along a third plane perpendicular to the first and second planes.

4. The device of claim 2 , wherein at least a portion of the plurality of wraps are intertwined over and under.

5. The device of claim 1 , further comprising a gasket disposed around the opening and extending between the container and the cap that is interfaced with the tube.

6. The device of claim 1 , further comprising a tube stabilizer disposed in the container and configured to stabilize within the container the tube spaced by the tube stabilizer from at least one wall of the container.

7. The device of claim 1 , further comprising an item stabilizer disposed in the tube and configured to stabilize within the tube an item spaced by the item stabilizer from at least one wall of the tube.

8. The device of claim 1 , wherein the tube and the cap each comprise a plurality of differently shaped sheets layered together, wherein a first seam of a first sheet does not align with a second seam of a second sheet.

9. The device of claim 1 , wherein the cap includes a flange disposed on an end of the cap, configured to extend outward from the cap to seal with the container.

10. The device of claim 9 , wherein the container includes a concavity around the door opening to accommodate the flange of the cap between the concavity and the door.

11. The device of claim 1 , wherein the door has a U-configuration including a first door panel, a second door panel spaced from the first door panel, and a side door panel connecting the first door panel to the second door panel.

12. The device of claim 11 , wherein the first door panel and the second door panel are spaced apart to sandwich a portion of the container.

13. A device comprising:
a container comprising an opening,
the container being a one-piece, three-dimensional structure;
the container formed from integrally woven, continuous fibers;
the container further comprising a foldable region connecting a front wall to the container;
the front wall comprising a door flap;
the door flap comprising overhangs; and
the overhangs of the door flap being stitched to a top wall of the container and side walls of the container to enclose the container;

a tube disposed in the container and aligned with the opening;
a cap configured to slidably interface with the tube through the opening; and
a door configured to slidably close the opening to enclose the cap within the container.
