US Patent 7040499 Container with primary closure and a secondary closure

Capped containers for use on a residence counter have caps which swingably connect the cap to the container for closure. If the contents of the container is a thin or watery liquid the ordinary closure may not prevent leakage during vibration, travelling or pressure. There is here provided a container with an additional closure formed when a sleeve is arranged to move to an extended position and then to thread to both the cap and the container to provide a fluid tight connection to each.
