Abstract: A container for transporting and storing vessels containing hazardous liquids and a method for making such a container. The container has a cylindrical housing and a cap that screws into the mouth of the housing and is locked by a latch. When the cap is screwed into place, an elastomeric sealing ring on the cap is compressed against the housing to provide a liquid-tight seal between the housing and cap. Interlocking hook-shaped members that project from the housing and from a central location of the latch act as a fulcrum on which the latch can be pivoted. Under the bias of a serpentine tongue, a locking member that projects from an end of the latch protrudes through a bore in the housing and is adapted to be received by a hole in the cap, thus locking the cap until the other end of the lever is depressed to disengage the locking member from the hole of the cap.
