Nozzle gasket and nozzle structure for purge load port

A purge load port, comprising:

• a nozzle structure including:
• a base including a base surface;
• a nozzle protruding from the base surface of the base, the nozzle including an end spaced apart from the base surface of the base;
• a nozzle hole extending into the end of the nozzle;
• and
• a lip structure at the end of the nozzle;
• a nozzle gasket mounted to the nozzle structure, the nozzle gasket extends around the nozzle, and the nozzle gasket including:
• a first end extends past the end of the nozzle;
• a second end opposite to the first end, wherein the second end is at the base surface of the base;
• a through hole extending from the first end to the second end;
• a seal structure at the first end;
• and
• a deformation structure at the second end.

A nozzle gasket, comprising:

• a central axis;
• a first end and a second end opposite to the first end;
• a through hole aligned with the central axis and extending from the first end to the second end;
• a seal structure at the first end, the seal structure including:
• a first annular surface of a first annular portion concentric with the central axis;
• a second annular surface of a second annular portion concentric with the central axis, the second annular surface surrounds the first annular surface;
• and
• an annular recess that extends between the first annular surface and the second annular surface, the annular recess separates the first annular surface from the second annular surface, the annular recess surrounds the first annular surface, and the annular recess is at an angle less than 90-degrees relative to the second annular surface;
• a deformation structure at the second end, the deformation structure configured to, in operation, deform when a container is placed on the seal structure.
