Abstract
A tank having a top surface with a top opening bounded by an upwardly extending tubular neck and a lid. A seal member on the lid is in sealing engagement with the neck inner surface so that the lid can move up and down without losing the seal. A lid retaining member is mounted on the top surface of the tank so as to retain the lid in a position in which the sealing engagement is maintained when the interior of said tank is pressurized so as to urge the lid upwardly and structure is provided for insuring against inadvertent removal of the retaining member.
