(under subclass 200) Device wherein a plug or stopper type closure or gasket therefor is provided with adjustment means
by which the plug or gasket may be expanded or contracted to or from its operable position, such adjustment means being located at a point external of the closed receptacle.
(1) Note. Plugs and gaskets therefor are found together in this subclass for it is impossible to determine, in most instances, when the expandable portion is a gasket or part of the closure itself.
