Abstract
An overpack is provided for packaging cylinders containing compressed gas. Cylinders containing compressed gas typically have a pressure relief mechanism that releases the gas from the cylinder when the pressure inside the cylinder approaches a pressure detrimental to the cylinder. In high heat, high temperature situations such as when the overpack is exposed to a fire, the overpack of the present invention extends the time that it takes for the cylinders to trigger the pressure relief mechanism.

An overpack for packing a cylinder containing a compressed gas, the overpack comprising:
- a first container having an outer surface, a first end, and a second end and being sized to be capable of receiving the cylinder;
- a first end cap spacer disposed at the first end of the first container;
- a second end cap spacer at the second end of the first container;
- and,
- a second container having an inner surface, the second container sized to receive the first container with the first end cap spacer and the second end cap spacer disposed thereon such that the outer surface of the first container is disposed in spaced apart relation to the inner surface of the second container;
- a thermal barrier disposed between the first container and the second container.

- a third container having an inner surface, the third container sized to receive the second container with the third end cap spacer, and the fourth end cap spacer disposed thereon such that the outer surface of the second container is disposed in spaced apart relation to the inner surface of the third container.
A method of packing a cylinder containing a compressed gas, comprising:
- placing a head ring at a first end of the cylinder;
- placing a bottom ring at a second end of the cylinder;
- inserting the cylinder into a first container;
- closing and sealing the first container;
- placing end cap spacers at each end of the first container to form a first container assembly;
- inserting the first container assembly into a second container such that an outer surface of the first container is disposed in spaced apart relation to an inner surface of the second container;
- providing a thermal barrier between the first and second container.
