Abstract

A cap for engagement with a beverage container allows an extractor needle or other conduit to pass through a portion of the cap such that beverage can be removed from the container without removing the cap. The cap may include a septum that is radially and/or axially compressed and a barrier layer arranged to engage with the container to form a seal.

First claim

The invention claimed is:

1. A cap for engaging a threaded neck at a container opening, the cap comprising:
a body having a lower cavity and an upper cavity that define a passageway from an upper opening to a lower opening of the body, the lower cavity defined by a sidewall with a thread arranged at an inner side of the sidewall to engage with the threaded neck;
a barrier material arranged in the passageway between the upper and lower openings to engage with the container opening to seal the opening closed upon threaded engagement of the body thread with the threaded neck of the container; and
a septum in the upper cavity of the body and positioned above the barrier material, the septum having an upper surface at the upper opening and being compressed by the body in radial and/or axial directions, the septum and the barrier material being arranged to be pierced by a needle extended from the upper opening toward the lower opening, the septum arranged to reseal to prevent leakage of beverage from the container or gas into the container after withdrawal of a needle that penetrates through the septum.

2. The cap of claim 1 , wherein the septum includes a block of silicone rubber.

3. The cap of claim 1 , wherein an annular ring extends inwardly from the sidewall between the barrier layer and the septum.

4. The cap of claim 3 , wherein the body includes an inner sidewall that extends upwardly from annular ring and contacts the septum.

5. The cap of claim 4 , further comprising a cover that has an annular shape and engages the body at the upper opening.

6. The cap of claim 3 , wherein the annular ring defines an opening through which the septum bulges due to compression of the septum.

7. The cap of claim 4 , wherein the septum is compressed in the radial direction by the inner sidewall.

8. The cap of claim 1 , wherein the septum is arranged to reseal after penetration by a needle having a diameter equal to 16 gauge or less.

9. The cap of claim 1 , wherein the septum is arranged in the body to be positioned outside of a container neck with the cap engaged with the container neck.

10. The cap of claim 1 , wherein the barrier layer is located in the lower cavity.

11. The cap of claim 1 , wherein the barrier layer is arranged to engage a top edge of a container neck to which the cap is attached.

12. The cap of claim 1 , wherein the barrier layer includes a circular sheet of laminate material.

13. The cap of claim 12 , wherein the laminate material includes a polystyrene layer, a PET layer, and a PVDC layer.

14. The cap of claim 1 , further comprising identification indicia configured to uniquely identify the cap from other caps.

15. The cap of claim 14 , wherein the identification indicia includes an RFID tag.

16. A cap for engaging a threaded neck at a container opening, the cap comprising:
a body having a lower cavity and an upper cavity that define a passageway from an upper opening to a lower opening of the body, the lower cavity defined by a sidewall and arranged to engage with the threaded neck;
a barrier material arranged in the passageway between the upper and lower openings to engage with the container opening to seal the opening closed; and
a septum in the upper cavity of the body, the septum having an upper surface at the upper opening and being compressed by the body in radial and/or axial directions, the septum being arranged to be pierced by a needle extended from the upper opening toward the lower opening, the septum arranged to reseal after withdrawal of a needle that penetrates through the septum,
wherein the cap, including the septum and barrier material, is arranged to prevent leakage of liquid or gas from the container with a pressure of 30 psi in the container and the needle pierced through the septum.

17. The cap of claim 16 , wherein the barrier material is out of contact with the septum.

18. The cap of claim 16 , wherein the septum is positioned above the barrier material, and the barrier material is arranged to be pierced by the needle extended from the upper opening toward the lower opening.

19. The cap of claim 16 , wherein the septum includes a block of silicone rubber.

20. The cap of claim 16 , wherein the body includes the sidewall and an annular ring extending inwardly from the sidewall between the barrier layer and the septum.

21. The cap of claim 20 , wherein the body includes an inner sidewall that extends upwardly from annular ring and contacts the septum.

22. The cap of claim 21 , further comprising a cover that has an annular shape and engages the body at the upper opening.

23. The cap of claim 21 , wherein the barrier layer is located below the annular ring.

24. The cap of claim 21 , wherein the septum is compressed in the radial direction by the inner sidewall.

25. The cap of claim 16 , wherein the septum is arranged to reseal after penetration by a needle having a diameter equal to 16 gauge or less.

26. The cap of claim 16 , wherein the septum is arranged in the body to be positioned outside of a container neck with the cap engaged with the container neck.

27. The cap of claim 16 , wherein the barrier layer is located in the lower cavity.

28. The cap of claim 16 , wherein the barrier layer is arranged to engage a top edge of a container neck to which the cap is attached.

29. The cap of claim 16 , wherein at least a portion of the upper cavity is positioned within the lower cavity.

30. The cap of claim 16 , wherein at least a portion of the lower cavity is positioned around the upper cavity.

31. The cap of claim 1 , wherein the septum is made to have a diameter that is larger than the upper cavity so that the body presses inwardly on the septum from radial directions when the septum is positioned in the upper cavity.

32. The cap of claim 1 , wherein a portion of the septum bulges into the upper opening due to compression of the septum.

33. The cap of claim 1 , wherein the cap is arranged to prevent leakage of liquid or gas from the container with a pressure of 30 psi in the container.
