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 container 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 upper cavity defined by an inner sidewall and at least partially positioned in the lower cavity, the lower cavity defined by an outer sidewall with an inner side and configured to receive the container neck with a portion of the inner sidewall and upper cavity positioned inside the container opening;
a barrier material arranged in the passageway between the upper and lower openings; 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 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, 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.

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

3. The cap of claim 1 , wherein the body includes an annular ring extending inwardly from the outer sidewall to the inner sidewall.

4. The cap of claim 1 , wherein the body is arranged to engage the container neck by friction fit.

5. 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.

6. The cap of claim 1 , wherein the barrier layer is located below the septum.

7. A cap for engaging a container 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 upper cavity defined by an inner sidewall and at least partially positioned in the lower cavity, the lower cavity defined by an outer sidewall with an inner side and configured to receive the container neck with a portion of the inner sidewall and upper cavity positioned inside the container opening;
a barrier material located in the lower cavity and arranged in the passageway between the upper and lower openings; 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 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 after withdrawal of a needle that penetrates through the septum.

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. A cap for engaging a container 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 upper cavity defined by an inner sidewall and at least partially positioned in the lower cavity, the lower cavity defined by an outer sidewall with an inner side and configured to receive the container neck with a portion of the inner sidewall and upper cavity positioned inside the container opening;
a barrier material arranged in the passageway between the upper and lower openings; 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 a portion of the septum bulges into the upper opening due to compression of the septum.

10. 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.

11. The cap of claim 1 , wherein the barrier layer includes a polystyrene layer, a PET layer, and a PVDC layer.

12. The cap of claim 1 , wherein the inner side of the outer sidewall includes a thread to threadedly engage with a threaded neck of the container.

13. The cap of claim 1 , wherein at least a portion of the lower cavity is positioned around the upper cavity.

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. The cap of claim 1 , 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.

17. The cap of claim 1 , 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 20 psi in the container and the needle pierced through the septum, the needle having a gauge of 17 to 20.

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

19. The cap of claim 7 , wherein the barrier layer has an inverted top hat shape such that a portion of the barrier layer covers a lower portion of the septum and a brim portion of the barrier layer is arranged to engage with a top edge of the container around the container opening.
