US Patent 8631632 Container pressurizing and sealing apparatus and methods of pressurizing containers

A process for pressurizing a container assembly includes engaging the outer container around a neck of the outer container at a location between a shoulder of the outer container and a mouth of the outer container with a neck clamp device. The neck clamp device is used to support the outer container as the outer container moves from one location to a different location. An at least partial seal is formed about the neck of the outer container by engaging the neck clamp device with an outer bell member of a crimper-pressurized fluid fill head.
