Abstract

A vial closure assembly for sealing a container includes a ring, a cap, a shell, and an optional cover. The ring has a first top wall defining a first through-opening and a skirt extending downwardly from the first top wall that includes a plurality of locking tabs. The cover includes a second top wall defining a second through-opening, a sidewall extending downwardly from the second top wall, and an interior cavity defined by the second top wall and the sidewall. The cap includes a plurality of tabs configured to engage the first or second top wall. The shell includes a body having an inwardly radially extending upper and lower lip. The upper lip includes at least one rail for sliding contact with a top surface of either the first or second top wall.

First claim

I claim:

1. A vial closure assembly comprising:
a ring comprising a first top wall and a skirt extending downwardly from the first top wall, the first top wall defining a first central through-opening, and the skirt comprising a plurality of locking tabs;
a cover comprising a second top wall and a sidewall extending downwardly from the second top wall, the second top wall and the sidewall defining an interior cavity, and the second top wall defining a second central through-opening aligned with the first central through-opening of the ring;
a cap comprising a plurality of tabs configured to engage the second top wall of the cover; and
a shell comprising a body having an upper lip extending radially inward and a lower lip extending radially inward, the upper lip including at least one rail configured to contact a top surface of the second top wall when the shell engages the cover.

2. The vial closure assembly of claim 1 , wherein the shell is configured to rotate independently of the cover.

3. The vial closure assembly of claim 1 , wherein the at least one rail is tapered and a tip of the at least one rail is configured to contact the top surface of the second top wall when the shell engages the cover.

4. The vial closure assembly of claim 1 , wherein the shell comprises a plurality of rails.

5. The vial closure assembly of claim 4 , wherein each rail of the plurality of rails is arcuate.

6. The vial closure assembly of claim 1 , wherein the ring, the cover, the shell, and the cap are made of a plastic material.

7. The vial closure assembly of claim 6 , wherein the plastic material is a pharmaceutical grade plastic material.

8. The vial closure assembly of claim 1 , wherein the skirt further comprises a flexible tongue and a recess configured to receive the flexible tongue.

9. The vial closure assembly of claim 1 , further comprising an elastomeric stopper comprising a flanged head and a cylindrical body extending downwardly from the flanged head, the elastomeric stopper being housed within the skirt of the ring.

10. A sealed container assembly comprising:
a container having a main body, a neck, and a rim defining an opening of the container; and
the vial closure assembly according to claim 9 , wherein the elastomeric stopper is in sealing contact with the opening of the container, and wherein the plurality of locking tabs engage a bottom surface of the rim.

11. The vial closure assembly of claim 1 , wherein the body of the shell is barrel-shaped.

12. A vial closure assembly comprising:
a ring comprising a top wall and a skirt extending downwardly from the top wall, the top wall defining a first central through-opening, and the skirt comprising a plurality of locking tabs;
a cap comprising a plurality of tabs configured to engage the top wall of the ring; and
a shell comprising a body having an upper lip extending radially inward and a lower lip extending radially inward, the upper lip including at least one rail configured to contact a top surface of the top wall of the ring when the shell engages the ring.

13. The vial closure assembly of claim 12 , wherein the at least one rail is tapered and a tip of the at least one rail is configured to contact the top surface of the top wall of the ring when the shell engages the ring.

14. The vial closure assembly of claim 12 , wherein the shell comprises a plurality of rails.

15. The vial closure assembly of claim 14 , wherein each rail of the plurality of rails is arcuate.

16. The vial closure assembly of claim 12 , wherein the ring, the shell, and the cap are made of a plastic material.

17. The vial closure assembly of claim 16 , wherein the plastic material is a pharmaceutical grade plastic material.

18. The vial closure assembly of claim 12 , wherein the skirt further comprises a flexible tongue and a recess configured to receive the flexible tongue.

19. The vial closure assembly of claim 12 , further comprising an elastomeric stopper comprising a flanged head and a cylindrical body extending downwardly from the flanged head, the elastomeric stopper being housed within the skirt of the ring.

20. A sealed container assembly comprising:
a container having a main body, a neck, and a rim defining an opening of the container; and
the vial closure assembly according to claim 19 , wherein the elastomeric stopper is in sealing contact with the opening of the container, and wherein the plurality of locking tabs engage a bottom surface of the rim.

21. The vial closure assembly of claim 12 , wherein the body of the shell is barrel-shaped.
