Abstract

A container for receiving fluids comprises a body having opposite ends and at least one wall defining an interior space. At least one seal defines a sealed chamber within the interior space of the body. Each seal is recessed from one of the ends of the body and has a sealing connection with the wall of the body. A cap sealingly closes each end of the body having a seal recessed therefrom.

Claims (25)

1. A container for receiving fluids comprising:

a body having opposite ends and at least one wall defining an interior space;

at least one seal defining a sealed chamber within the interior space of the body for receiving fluids, each seal having a sealing connection with said at least one wall of the body and being recessed from one of said opposite ends of the body;

fluid sampling media disposed within said sealed chamber; and

a cap for sealingly closing each end of said body having a seal recessed therefrom.

2. A container as set forth in claim 1 wherein said body is a tube, and wherein said at least one wall is a tubular wall.

3. A container as set forth in claim 2 wherein said at least one seal comprises two seals.

4. A container as set forth in claim 3 wherein said seals comprise frangible seals.

5. A container as set forth in claim 4 wherein each of said frangible seals comprises a partition extending across the interior of the tube and having a sealing connection to said tube around a periphery of the partition, an opening in said partition, and a frangible sealing element connected to said partition and sealing said opening, said frangible element projecting from the partition in a direction away from said sealed chamber, said frangible element being adapted to be selectively broken to open said opening.

6. A container as set forth in claim 1 wherein said fluid sampling media comprises air sampling media.

7. A container as set forth in claim 1 wherein said body is a cylindrical body and wherein said opposite ends comprise a first closed end and a second end opposite the first end.

8. A container as set forth in claim 7 wherein said at least one seal comprises one frangible seal recessed from said second end.

9. A container as set forth in claim 8 wherein said frangible seal comprising a partition extending across the interior of the body and having a sealing connection to said wall around a periphery of the partition, a fluid flow opening in said partition, and a frangible sealing element connected to said partition and sealing said opening, said frangible element projecting from the partition in a direction away from said sealed chamber, said frangible element being adapted to be selectively broken to open said fluid flow opening.

10. A container as set forth in claim 9 wherein said fluid is a liquid.

11. A container as set forth in claim 1 wherein said body is made of glass.

12. A container as set forth in claim 1 wherein said fluid sampling media is selected from a group consisting of a filter, granular charcoal, granular carbon, and silica gel.

13. A container as set forth in claim 1 further comprising at least one permeable retaining plug for holding the fluid sampling media within the sealed chambered.

14. A container as set forth in claim 1 in combination with a pump for drawing a predetermined volume of fluid into the container.

15. A container for receiving fluids comprising:

a body having opposite ends and at least one wall defining an interior space;

at least one frangible seal defining a sealed chamber within the interior space of the body for receiving fluids, each frangible seal having a sealing connection with said at least one wall of the body and being recessed from one of said opposite ends of the body, each of said frangible seals comprising a partition extending across the interior of the body and having a sealing connection to said body around a periphery of the partition, an opening in said partition, and a frangible sealing element connected to said partition and sealing said opening, said frangible element projecting from the partition in a direction away from said sealed chamber, said frangible element being adapted to be selectively broken to open said opening, each of said frangible seals being made of glass; and

a cap for sealingly closing each end of said body having a seal recessed therefrom.

16. A container as set forth in claim 15 wherein said body is a tube, and wherein said at least one wall is a tubular wall.

17. A container as set forth in claim 15 wherein said at least one seal comprises two seals.

18. A container as set forth in claim 15 in combination with a tool sized and shaped for insertion into one of the ends of the body to engage and break the frangible seal.
