US Patent 10276274 Sealing container and method of use

Containers for sealing and shielding radioactive fluid are disclosed. Methods of manufacturing such containers are also disclosed. The container is arranged to maintain a fluid tight seal to contain radioactive fluid when subjected to environmental forces, while also permitting a user to manually remove the cap from the container body when desired. In some embodiments, the container includes a container body with an inner chamber, along with an associated cap. The cap forms a fluid tight seal with the body by way of an interference fit between a sealing element and a burnished abutment surface.
