Abstract
A cryogenic storage apparatus including housing, inner storage tank which may contain cryogenic fluid such as liquid nitrogen, and a lid which is used to access the storage tank. The lid preferably completely seals the storage tank when in a closed position, and includes a vent path formed between the storage tank and ambient. This vent path leads to the rear of the housing. A flap valve is mounted to the exit point of the vent path to allow escape of evaporated liquid nitrogen as necessary.
