Abstract

A spout assembly for use with a container having an internal chamber in communication with a predefined opening that is sealed with a frangible sealing material includes a base member, a hollow body, and a puncture member. The base member is configured to be secured to the container, and is further configured to cover the predefined opening. The hollow body defines a passage therethrough and is rotatably mounted to the base member to be movable between an open position and a closed position. The puncture member is formed with the hollow body, the puncture member configured to puncture the sealing member when the hollow body is moved from the closed position to the open position.

Claims

1. A spout assembly for use with a container having an internal chamber in communication with a predefined opening that is sealed with a frangible sealing material, the spout assembly comprising:

a base member configured to be secured to the container, the base member configured to cover the predefined opening;

a hollow body defining a passage therethrough, the hollow body rotatably mounted to the base member to be movable between an open position and a closed position;

a puncture member formed with said hollow body, the puncture member configured to puncture the sealing member when the hollow body is moved from the closed position to the open position.

2. The spout assembly of claim 1 wherein the base member includes a cavity for receiving the hollow body in the closed position.

3. The spout assembly of claim 2 wherein the base member includes first and second side walls extending at least to a top surface of the hollow body when the hollow body is in the closed position.

4. The spout assembly of claim 3 wherein the hollow body includes an overhang on the top surface.

5. The spout assembly of claim 1 wherein the hollow body includes an overhang on a top surface thereof.

6. The spout assembly of claim 1 wherein at least one of the hollow body or base member includes a first detent for engaging a first feature in the other of the hollow body or base member when the hollow body is in the closed position.

7. The spout assembly of claim 6 wherein at least one of the hollow body or base member includes a second detent for engaging a second feature in the other of the hollow body or base member when the hollow body is a first non-closed position, the passage and the predefined opening in the chamber in communication in the first non-closed position.

8. The spout assembly of claim 1 wherein at least one of the hollow body or base member includes a first detent for engaging a first feature in the other of the hollow body or base member when the hollow body is a first non-closed position, the passage and the predefined opening in the chamber in communication in the first non-closed position.

9. The spout assembly of claim 6 wherein the hollow body includes the first detent and the first feature comprises a recess in the base member.

10. The spout assembly of claim 1 further comprising an adhesive for securing the base member to the container.

11. The spout assembly of claim 1 wherein the base member further comprises a venting aperture defined therethrough, the venting aperture in venting communication with the internal chamber, and wherein the hollow body covers the venting aperture when in the closed position.

13. The spout assembly of claim 12 wherein the first detent extends from a side surface of the hollow body.

14. The spout assembly of claim 13 wherein the base member includes the second detent.

15. The spout assembly of claim 12 wherein the base member includes the second detent

16. The spout assembly of claim 13 wherein the hollow body includes an additional detent disposed on an opposite side surface.

17. The spout assembly of claim 12 wherein the rotatably mounted hollow body defines an axis of rotation, and the first detent comprises a protrusion in the hollow body extending in the axial direction with respect to the axis of rotation.

18. The spout assembly of claim 17 wherein the first feature comprises a recess in the base member.

19. The spout assembly of claim 14 wherein the rotatably mounted hollow body defines an axis of rotation, and the second feature comprises a concavity in the hollow body defined in the radial direction with respect to the axis of rotation.

20. The spout assembly of claim 12 wherein the base member includes a cavity for receiving the hollow body in the closed position.

21. The spout assembly of claim 12 wherein the hollow body includes an overhang on a top surface thereof.

12. A spout assembly for use with a container having an internal chamber in communication with a predefined opening, the spout assembly comprising:

a base member configured to be secured to the container;

a hollow body defining a passage therethrough, the hollow body rotatably mounted to the base member to be movable between a non-closed position and a closed position, the passage and the predefined opening in the chamber being in communication in the non-closed position;

wherein at least one of the hollow body or base member includes a first detent for engaging a first feature in the other of the hollow body or base member when the hollow body is in the closed position and at least one of the hollow body or base member includes a second detent for engaging a second feature in the other of the hollow body or base member when the hollow body is the non-closed position.

22. A container assembly comprising:

a container having an internal chamber and a surface in which is defined an opening;

a frangible sealing member affixed to the container to seal the defined opening;

a hollow body defining a passage therethrough, the hollow body rotatably mounted to the container to be movable between an open position and a closed position;

a puncture member formed with said hollow body, the puncture member configured to puncture the sealing member when the hollow body is moved from the closed position to the open position.

23. The container assembly of claim 22, wherein the container further comprises a base member, and wherein the hollow body is rotatably mounted to the base member.

24. The container assembly of claim 22, wherein the container includes a cavity for receiving the hollow body in the closed position.

25. The container assembly of claim 24 wherein the hollow body includes an overhang on the top surface.

26. The container assembly of claim 22 wherein the hollow body includes an overhang on a top surface thereof.

27. The container assembly of claim 22 wherein at least one of the hollow body or container includes a first detent for engaging a first feature in the other of the hollow body or container when the hollow body is in the closed position.

28. The container assembly of claim 27 wherein at least one of the hollow body or container includes a second detent for engaging a second feature in the other of the hollow body or container when the hollow body is a first non-closed position, the passage and the predefined opening in the chamber in communication in the first non-closed position.

29. The container assembly of claim 22 wherein at least one of the hollow body or container includes a first detent for engaging a first feature in the other of the hollow body or container when the hollow body is a first non-closed position, the passage and the predefined opening in the chamber in communication in the first non-closed position.

30. The container assembly of claim 27 wherein the hollow body includes the first detent and the first feature comprises a recess in the container.

31. The container assembly of claim 30 wherein the container further comprises a base member, the base member including the recess.
