  • Radiation-shielding container
    Patent number: 6781142
    Abstract: A radiation-shielding container has an elongated cylindrical base and a cylindrical cap that define a cavity. A reduced portion of the cap extends into the base and includes a planar end surface that engages an internal shoulder within the base, and an external shoulder that engages an annular end surface of the base. The cap is secured to the base by rotating the cap such that tabs defined on the reduced portion slide along inwardly sloping lower engagement surfaces of the base until the tabs abut stop surfaces of the base and are secured by upper engagement surfaces. Removal of the cap is accomplished by rotating the cap in the opposite direction to disengage the tabs from the upper engagement surfaces.
