Abstract

A blast containment system for trash cans includes a liquid-impervious flexible bag having a sealed bottom positioned at a base of a trash can, and an unsealed top positioned and retained at a top periphery of the trash can. A ring-shaped boot is positioned at the sealed bottom of the flexible bag. A rigid container has a closed bottom press-fit into a central opening of the boot. The rigid container extends from its closed bottom to an open top adapted to be approximately aligned with the top periphery of the trash can. An annular volume is defined between the rigid container the flexible bag. The rigid container has side walls that include ballistic materials. A liquid fills the annular volume.

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 trash cans, comprising:
a flexible bag being adapted for positioning in a rigid trash can, said flexible bag includes a sealed bottom adapted to be positioned at a base of the trash can, said flexible bag includes an unsealed top adapted to be positioned and retained at a top periphery of the trash can, said flexible bag is impervious to liquid;
a ring-shaped boot being positioned at said sealed bottom of said flexible bag, said ring-shaped boot includes a central opening;
a rigid container including a closed bottom being press-fit into said central opening of said ring-shaped boot, said rigid container extends from said closed bottom to an open top thereof adapted to be approximately aligned with the top periphery of the trash can, wherein an annular volume is defined between said rigid container and said flexible bag, said rigid container includes side walls, which include ballistic materials; and
a liquid filling said annular volume.

2. The blast containment system as in claim 1 , further comprising a retainer for engaging said unsealed top of said flexile bag and for adapting to engage the top periphery of the trash can, wherein said unsealed top of said flexible bag is maintained at the top periphery of the trash can.

3. The blast containment system as in claim 2 , wherein said retainer is integrated with said unsealed top of said flexible bag.

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

5. The blast containment system as in claim 1 , wherein side walls of said flexible bag include at least one material selected from the group consisting of rubber, Kevlar, Lexan, graphene, and carbon fibers.

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

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

8. The blast containment system as in claim 1 , wherein said boot comprises a semi-flexible rubber material.

9. The blast containment system as in claim 1 , wherein said ballistic materials comprising said side walls of said rigid container are selected from the group consisting of ceramics, steel, titanium, rubber, Kevlar, Lexan, graphene, and carbon fibers.

10. A blast containment system for trash cans, comprising:
a flexible bag being adapted for positioning in a rigid trash can, said flexible bag includes a sealed bottom adapted to be positioned at a base of the trash can, said flexible bag includes an unsealed top adapted to be positioned and retained at a top periphery of the trash can, said flexible bag is impervious to liquid;
a retainer for engaging said unsealed top of said flexile bag and being adapted for engaging the top periphery of the trash can, wherein said unsealed top of said flexible bag is maintained at the top periphery of the trash can;
a rubber boot being positioned at said sealed bottom of said flexible bag, said rubber boot includes a central opening;
a rigid container including a closed bottom press-fit into said central opening of said rubber boot, said rigid container extends from said closed bottom to an open top thereof adapted to be approximately aligned with the top periphery of the trash can, wherein an annular volume is defined between said rigid container and said flexible bag, said rigid container having side walls that include ballistic materials; and
a liquid filling said annular volume.

11. The blast containment system as in claim 10 , wherein said retainer is integrated with said unsealed top of said flexible bag.

12. The blast containment system as in claim 10 , wherein side walls of said flexible bag include at least one material selected from the group consisting of rubber, Kevlar, Lexan, graphene, and carbon fibers.

13. The blast containment system as in claim 10 , wherein said liquid includes water.

14. The blast containment system as in claim 13 , wherein said liquid includes at least one solute selected from the group consisting of an antifreeze additive and cornstarch.

15. The blast containment system as in claim 10 , wherein said ballistic materials comprising said side walls of said rigid container are selected from the group consisting of ceramics, steel, titanium, rubber, Kevlar, Lexan, graphene, and carbon fibers.

16. A blast containment system for trash cans, comprising:
a flexible bag being adapted for positioning in a rigid trash can, said flexible bag includes a sealed bottom adapted to be positioned at a base of the trash can, said flexible bag includes an unsealed top adapted to be positioned and retained at a top periphery of the trash can, said flexible bag is impervious to liquid;
a retainer for engaging said unsealed top of said flexile bag and adapted for engaging the top periphery of the trash can, wherein said unsealed top of said flexible bag is maintained at the top periphery of the trash can;
a ring-shaped boot being positioned at said sealed bottom of said flexible bag, said ring-shaped boot includes a central opening;
a rigid container including a closed bottom press-fit into said central opening of said ring-shaped boot, said rigid container extends from said closed bottom to an open top thereof adapted to be approximately aligned with the top periphery of the trash can, wherein an annular volume is defined between said rigid container and said flexible bag, said rigid container includes side walls, which include ballistic materials; and
a liquid filling said annular volume, wherein said liquid includes water and at least one solute selected from the group consisting of an antifreeze additive and cornstarch.

17. The blast containment system as in claim 16 , wherein said retainer is integrated with said unsealed top of said flexible bag.

18. The blast containment system as in claim 16 , wherein side walls of said flexible bag include at least one material selected from the group consisting of rubber, Kevlar, Lexan, graphene, and carbon fibers.

19. The blast containment system as in claim 16 , wherein said boot comprises a semi-flexible rubber material.

20. The blast containment system as in claim 16 , wherein said ballistic materials comprising said side walls of said rigid container are selected from the group consisting of ceramics, steel, titanium, rubber, Kevlar, Lexan, graphene, and carbon fibers.
