Patent attributes
A secure storage device includes a container having a void for external access to the interior space. A closure lid, similarly dimensioned according to the void, may be joined to the container and can be manipulated between an open or closed state. An air evacuation system is also provided including a pressure release valve, a pressure indicator, and a pressure control system, such as a pump, for providing pressure to move air through a fluid communication channel from the interior space to the exterior of the container. A lock is fixed to the closure lid to conditionally restrict a change in state of the closure lid in response to an access control system. The access control system is configured to present an input, validate user input, and permit a state change of the lock.
