Abstract

A self-sealing container, used for transferring one or more air sensitive samples between vacuum systems, includes a housing with a cavity that holds the sample(s), and a lid disposed on top of the housing. The lid is configured to interface with the housing to form a seal over the cavity when the lid is closed. At least two flexure systems, each coupled to the housing and the lid, are disposed on opposing sides of the housing. The flexure systems apply forces to the lid that move the lid horizontally and vertically above the housing, into an open position. A pneumatic actuator, movably coupled to the housing and the lid, that is actuated by a change in ambient pressure. When actuated, it applies forces that move the lid horizontally and vertically to the closed position, in opposition to and in excess of the forces applied by the flexure systems.
