(under subclass 377) Guards and shields which comprise (1) a cylindrical or conical member attached to the spout of the fluent material device to prevent contamination of the spout either during or after the flow of fluent material; or (2) a movable shield that covers the outlet area or spout when not in use.
(1) Note. Where the movable guard covers only the outlet end of the spout and actually closes it against flow, it is considered to be a valve or closure and classification is on that basis.
