Filling devices, systems and methods for transferring hazardous waste material into a sealable container

A system for transferring hazardous waste material into a sealable container, the system comprising:

• a container configured to sealingly contain the hazardous waste material, the container including a filling port;
• a hopper for supplying hazardous waste material;
• a filling nozzle having:
• a valve body having a distal end, an inner surface, and an outer surface, the valve body including a valve seat proximate the distal end, the outer surface proximate the distal end being configured to sealingly and removeably couple the valve body to an inner surface of a filling port of the container,
• a valve head;
• a valve stem extending axially from the valve head through at least a portion of the valve body;
• a passage defined between the valve stem and the inner surface of the valve body, the passage being fluidly coupled to the hopper for transfer of hazardous waste material from the hopper;
• and
• a vacuum nozzle sealingly and removably couplable with an exhaust port in the distal end of the valve body, the vacuum nozzle being in sealed fluid communication with the valve body in a filling configuration;
• wherein the valve head has a valve face configured to form a seal with the valve seat proximate the distal end in a closed configuration to seal the filling nozzle, the valve head configured to allow the passage and the container to be fluidly coupled with one another in an open configuration in use for transfer of hazardous waste material from the passage into the container,
• wherein, in the open configuration in use, the valve head extends distally from the valve body and into the container, and
• wherein the outer surface of the valve body includes a first seal proximate the distal end to sealingly engage the inner surface of the filling port and a second seal, spaced from the first seal, to further sealingly engage the inner surface of the filling port.
