Abstract
The combination of a reusable lid and a container, the lid being provided with external threads and the container being provided with internal threads adjacent its upper end for mating with said external threads. The lid is assembled to the container by engagement of the external and internal threads on the lid and container respectively. Preferably the lid has a sealing ring disposed adjacent to the underside of an outer peripheral ledge for engagement with a selected portion of the container, so as to tightly seal off the contents of the container. A latch element is formed on the lid for engagement with a cooperating catch element formed on the container. The latch element prevents removal of the lid from the container until the latching element is released from the catch element.
