Abstract

A capping system for a container having a valve stem, comprising: a flexible tether having a first end region, a second end region, and a central region between the first and second end regions. A first connector is located at the first end region for attaching the tethered capping system to the container. A first cap is located in one of the central and second end regions and sized to frictionally fit over the valve stem. The other of the central and second end regions has a second connector for attaching a second cap to the tether. The second cap may be a threaded pressure cap for correspondingly engaging threads located on the valve stem. In alternative embodiments, the first connector can be located in the central region, and the first cap and second connector for the second cap are located in the first and second end regions.

Claims

1. A capping system for a container having a valve stem, comprising:

a flexible tether having a first end region, a second opposite end region, and a central region between the first and second end regions;

a first connector located in one of the central or end regions for attaching the tether to the container;

a first cap located in a different one of the central or end regions sized to frictionally fit over the valve stem; and

wherein a second connector for attaching a second cap to the tether is located in a remaining one of the central or end regions.

2. The capping system of claim 1, wherein the first cap is integrally formed in one of the central and second end regions.

3. The capping system of claim 1, wherein the first cap has first and second ends, the first end being sized to frictionally fit over the valve stem, and the second end including a connecting portion for frictionally attaching the second cap to the first cap.

4. The capping system of claim 3, wherein the second cap is attached to the second connector, and the tether flexes to allow the second cap to be received within the connecting portion of the first cap.

5. The capping system of claim 1, wherein the second cap is rotatable relative to the second connector.

6. The capping system of claim 5, wherein the second cap is connected by way of a snap ring connector.

7. The capping system of claim 5, wherein the second cap is connected by way of a pin and ring connector.

8. A capping system for a container having a valve stem, comprising:

a flexible tether having a first end region, a second opposite end region, and a central region between the first and second end regions;

a first connector in the first end region for attaching the tether to the container;

a first cap located in the central end region and sized to frictionally fit over the valve stem;

a second connector in the second opposite end region; and

a second cap attached to the second connector, the first and second caps being attached to the tether.

9. The capping system of claim 8, wherein the first cap is integrally formed with the tether.

10. The capping system of claim 8, wherein the first cap has first and second ends, the first end being sized to frictionally fit over the valve stem, and the second end including a connecting portion for frictionally attaching the second cap to the first cap.

11. The capping system of claim 10, wherein the second cap is attached to the second connector, and the tether flexes to allow the second cap to be removably received within the connecting portion of the first cap.

12. The capping system of claim 8, wherein the second cap is rotatable relative to the second connector.

13. The capping system of claim 12, wherein the second cap is connected by way of a snap ring connector.

14. The capping system of claim 12, wherein the second cap is connected by way of a pin and ring connector.

15. The capping system of claim 8, wherein the tether and first cap are made of a flexible resin and the second cap is made of a less flexible resin containing at least 33% glass fiber.

16. A capping system for a container having a valve stem, comprising:

a flexible tether having a first end region, a second opposite end region, and a central region between the first and second end regions;

a first connector in the first end region for attaching the tether to the container;

a first cap located in the second end region and sized to frictionally fit over the valve stem; and

a second connector in the central region; and

a second cap attached to the second connector, the first and second caps being attached to the tether.

17. The capping system of claim 16, wherein the first cap is integrally formed with the tether.

18. The capping system of claim 16, wherein the first cap has first and second ends, the first end being sized to frictionally fit over the valve stem, and the second end including a connecting portion for frictionally attaching the second cap to the first cap.

19. The capping system of claim 16, wherein the second cap is rotatable relative to the second connector.

20. The capping system of claim 18, wherein the second cap is attached to the second connector, and the tether flexes to allow the second cap to be received within the connecting portion of the first cap.

21. The capping system of claim 20, wherein the second cap is connected by way of a snap ring connector.

22. The capping system of claim 20, wherein the second cap is connected by way of a pin and ring connector.

23. The capping system of claim 16, wherein the tether and first cap are made of a flexible resin and the second cap is made of a less flexible resin containing at least 33% glass fiber.

24. A capping system for a container having a valve stem, comprising:

a flexible tether having a first end region, a second opposite end region, and a central region between the first and second end regions;

a first connector in the central region for attaching the tether to the container;

a first cap located in the first end region and sized to frictionally fit over the valve stem; and

a second connector in the second end region; and

a second cap attached to the second connector, the first and second caps being attached to the tether.

25. The capping system of claim 24, wherein the first cap is integrally formed with the tether.

26. The capping system of claim 24, wherein the first cap has first and second ends, the first end being sized to frictionally fit over the valve stem, and the second end including a connecting portion for frictionally attaching the second cap to the first cap.

27. The capping system of claim 24, wherein the second cap is rotatable relative to the second connector.

28. The capping system of claim 26, wherein the second cap is attached to the second connector, and the tether flexes to allow the second cap to be received within the connecting portion of the first cap.

29. The capping system of claim 28, wherein the second cap is connected by way of a snap ring connector.
