Abstract

A closure assembly is provided for a specimen collection container. The closure assembly includes a bottom ring and top ring assembly. The bottom ring is removably attachable to the open end of the container. The top ring assembly, which is removably attached to the bottom ring, includes a mounting ring and a pierceable, resealable septum that closes the bottom ring and permits pierceable instrument access therethrough. The container interior can also be accessed by the removal of the bottom ring from the open end of the container or by the removal of the top assembly from the bottom ring.

Claims

1. A closure assembly for a specimen collection container having an open end, an opposed closed end, and a side wall therebetween, defining a container interior, said closure assembly comprising:

a bottom ring removably attachable to said open end of said container; and

a top ring assembly removably attachable to said bottom ring when said bottom ring is attached to said container for closing said open end of said container, said top ring assembly including;

a mounting ring removably attachable to said bottom ring, said mounting ring having an opening therein for communication with said container interior, said mounting ring comprising an annular projection extending around an outer circumference of the mounting ring adapted to engage a cooperative structure in said bottom ring in a snap fit arrangement so as to secure said mounting ring to said bottom ring in a fixed coaxial relationship; and

a pierceable, resealable septum closing said opening and permitting pierceable instrument access therethrough.

2. The closure assembly of claim 1, wherein said container interior is further accessible through said open end by said removal of said bottom ring from said open end and by said removal of said mounting ring from said bottom ring.

3. The closure assembly of claim 1, wherein said top ring assembly further comprises a barrier having a top face and a bottom face, said top face of said barrier supported adjacent said septum.

4. The closure assembly of claim 3, wherein said barrier is adhesively supported to said septum.

5. The closure assembly of claim 3, wherein said barrier further includes a foil layer.

6. The closure assembly of claim 1, wherein said bottom ring is internally screw threaded for removable screw attachment with the open end of said container.

7. The closure assembly of claim 1, wherein said septum is formed of a thermoplastic elastomer.

8. The closure assembly of claim 1, wherein said septum is supported within said mounting ring opening by a force-fit.

9. The closure assembly of claim 1, wherein said mounting ring further comprises an annular shoulder.

10. The closure assembly of claim 9, wherein said annular shoulder is adapted to engage a top of a sidewall of said bottom ring.

11. The closure assembly of claim 1, wherein said mounting ring is removably secured to said bottom ring.

12. A resealable specimen collection container comprising:

a container body having an open end, a closed end, and a cylindrical side wall therebetween defining a container interior;

a closure assembly for closing said open end of said container body, said closure assembly including;

a bottom ring removably attachable to said open end of said container; and

a top ring assembly removably attachable to said bottom ring for closing said open end of said container, said top ring assembly further including;

a mounting ring removably attachable to said bottom ring when said bottom ring is attached to said container, said mounting ring having an opening therein for communication with said container interior, said mounting ring comprising an annular projection extending around an outer circumference of the mounting ring adapted to engage a cooperative structure in said bottom ring in a snap fit arrangement so as to secure said mounting ring to said bottom ring in a fixed coaxial relationship; and

a pierceable, resealable septum closing said opening and permitting pierceable instrument access therethrough.

13. The resealable specimen collection container of claim 12, wherein said container interior is further accessible through said open end by said removal of said bottom ring from said open end and by said removal of said mounting ring from said bottom ring.

14. The resealable specimen collection container of claim 12, wherein said top ring assembly further comprises a barrier having a top face and a bottom face, said top face of said barrier supported adjacent said septum.

15. The resealable specimen collection container of claim 14, wherein said barrier is adhesively supported to said septum.

16. The resealable specimen collection container of claim 14, wherein said barrier further includes a foil layer.

17. The resealable specimen collection container of claim 12, wherein said bottom ring is internally screw threaded for removable screw attachment with the open end of said container.

18. The resealable specimen collection container of claim 12, wherein said septum is formed of a thermoplastic elastomer.

19. The resealable specimen collection container of claim 12, wherein said septum is supported within said mounting ring opening by a force-fit.

20. The resealable specimen collection container of claim 12, wherein said mounting ring further comprises an annular shoulder.

21. The resealable specimen collection container of claim 20, wherein said annular shoulder is adapted to engage a top of a sidewall of said bottom ring.

22. The resealable specimen collection container of claim 12, wherein said mounting ring is removably secured to said bottom ring.

23. A kit of parts adapted for closing a specimen collection container having an open end, a closed end, and a cylindrical side wall defining a container interior, said kit of parts comprising:

a bottom ring removably attachable to said open end of said container;

a top ring assembly adapted for removable attachment to said bottom ring when said bottom ring is attached to said container for closing said container open end, said top ring assembly including;

a mounting ring removably attachable to said bottom ring, said mounting ring comprising an annular projection extending around an outer circumference of the mounting ring adapted to engage a cooperative structure in said bottom ring in a snap fit arrangement so as to secure said mounting ring to said bottom ring in a fixed coaxial relationship;

a pierceable septum for permitting instrument access to said container interior therethrough; and

a replacement ring adapted for removable attachment to said bottom ring for closing said open end of said container.

24. The kit of parts of claim 23, wherein said top ring assembly further comprises a barrier having a top face and a bottom face, said top face of said barrier supported adjacent said septum.

25. The kit of parts of claim 24, wherein said barrier is adhesively supported to said septum.

26. The kit of parts of claim 25, wherein said barrier further includes a foil layer.

27. The kit of parts of claim 23, wherein said bottom ring is internally screw threaded for removable screw attachment with the open end of said container.

28. The kit of parts of claim 23, wherein said septum is formed of a thermoplastic elastomer.

29. The kit of parts of claim 23, wherein said septum is supported within said mounting ring opening by a force-fit.

30. The kit of parts of claim 23, wherein said bottom ring and said replacement top ring include cooperative structure for removable snap fit engagement therebetween.

31. The kit of parts of claim 23, wherein said mounting ring further comprises an annular shoulder.

32. The kit of parts of claim 31, wherein said annular shoulder is adapted to engage a top of a sidewall of said bottom ring.
