Abstract

A blast containment system for trash cans includes a donut-shaped bag having a sealed donut-shaped bottom positioned at the base of the trash can, and an open donut-shaped top positioned and retained at a top periphery of the trash can. An open-ended tubular region extends through the bag between its donut-shaped top and donut-shaped bottom. A rigid container having an open top is disposed in the tubular region of the bag with its open top being coupled to the donut-shaped top of the bag. A liquid fills the bag. A ballistic fabric is situated inside of the trash can and outside of the donut-shaped bag.

First claim

What is claimed as new and desired to be secured by Letters Patent of the United States is:

1. A blast containment system for a trash can, comprising:
a flexible donut-shaped bag being adapted for positioning in the trash can, said bag includes a sealed donut-shaped bottom adapted to be positioned at a base of the trash can, said bag includes an open donut-shaped top adapted to be positioned and retained at a top periphery of the trash can wherein an open-ended tubular region extends through said bag between said donut-shaped top and said donut-shaped bottom, and said bag is impervious to liquid;
a rigid container having an open top disposed in said tubular region of said bag, said open top coupled to said donut-shaped top of said bag, said open top adapted to be approximately aligned with the top periphery of the trash can, said rigid container includes side walls comprised of ballistic materials;
a liquid filling said flexible donut-shaped bag; and
a ballistic fabric being situated inside of the trash can and outside of the flexible donut-shaped bag.

2. The blast containment system as in claim 1 , further comprising retainers for attaching said donut-shaped top of said bag to said rigid container and being adapted for attaching s donut-shaped top of said bag to the top periphery of the trash can.

3. The blast containment system as in claim 1 , wherein said bag comprises a rubber material.

4. The blast containment system as in claim 1 , wherein said bag includes interior sidewalls and exterior sidewalls, wherein the side walls of the bag are comprised of at least one of rubber, Kevlar, Lexan, graphene, and carbon fibers.

5. The blast containment system as in claim 1 , wherein said liquid includes water.

6. The blast containment system as in claim 5 , wherein said liquid includes at least one solute selected from the group consisting of an antifreeze additive and cornstarch.

7. The blast containment system as in claim 1 , wherein said ballistic materials of the rigid container are selected from at least one of ceramics, steel, titanium, rubber, Kevlar, Lexan, graphene, and carbon fibers.

8. A blast containment system for trash cans, comprising:
a flexible donut-shaped bag being adapted for positioning in a rigid trash can, said bag includes a sealed donut-shaped bottom adapted to be positioned at a base of the trash can, said bag includes an open donut-shaped top adapted to be positioned at a top periphery of the trash can wherein an open-ended tubular region extends through said bag between said donut-shaped top and said donut-shaped bottom, and said bag is impervious to liquid;
a rigid container having an open top being disposed in said tubular region of said bag, said open top coupled to said donut-shaped top of said bag, said open top adapted to be approximately aligned with the top periphery of the trash can, and said rigid container has side walls, wherein the side walls include ballistic materials;
retainers for attaching said donut-shaped top of said bag to said rigid container and being adapted to attach said donut-shaped top of said bag to the top periphery of the trash can;
a liquid to include water filling said bag; and
a ballistic fabric being situated intermediate inside of the rigid trash can, and outside and around the flexible donut-shaped bag.

9. The blast containment system as in claim 8 , wherein said bag comprises a rubber material.

10. The blast containment system as in claim 1 , wherein said bag includes interior sidewalls and exterior sidewalls, wherein the side walls of the bag are comprised of at least one of rubber, Kevlar, Lexan, graphene, and carbon fibers.

11. The blast containment system as in claim 8 , wherein said liquid further includes at least one solute selected from the group consisting of an antifreeze additive and cornstarch.

12. The blast containment system as in claim 8 , wherein said ballistic materials of the rigid container are comprised of at least one of ceramics, steel, titanium, rubber, Kevlar, Lexan, graphene, and carbon fibers.

13. A blast containment system for a trash can comprising an interior side wall surface, comprising:
a flexible donut-shaped bag being adapted for positioning in the trash can, said bag includes a sealed donut-shaped bottom adapted to be positioned at a base of the trash can, said bag includes an open donut-shaped top adapted to be positioned and retained at a top periphery of the trash can wherein an open-ended tubular region extends through said bag between said donut-shaped top and said donut-shaped bottom, said bag is impervious to liquid, wherein said bag includes interior side walls and exterior side walls;
a rigid container having an open top disposed in said tubular region of said bag, said open top coupled to said donut-shaped top of said bag, said open top adapted to be approximately aligned with the top periphery of the trash can, said rigid container has side walls which include ballistic materials selected from the group consisting of ceramics, steel, titanium, rubber, Kevlar, Lexan, graphene, and carbon fibers;
a liquid filling said bag; and
a ballistic fabric being situated intermediate the exterior side walls of the bag and the interior side wall surface of the trash can.

14. The blast containment system as in claim 13 , further comprising retainers for attaching said donut-shaped top of said bag for said rigid container and being adapted to attach said donut-shaped top of said bag to the top periphery of the trash can.

15. The blast containment system as in claim 13 , wherein said liquid includes water.

16. The blast containment system as in claim 15 , wherein said liquid includes at least one solute selected from the group consisting of an antifreeze additive and cornstarch.

17. The blast containment system for a trash can as in claim 13 , wherein the trash can is a rigid-trash can.
