Abstract
Abstract An internally threaded mounting ring including a laterally outwardly displaced and axially extending handle. The mounting ring is engageable with the externally threaded neck of a vacuum bottle and includes an outer end radially inwardly projecting retaining flange for overlying the end edge of the neck of the associated vacuum bottle. A sleeve is also provided and includes a small diameter end for tight telescopic engagement within the neck of the associated vacuum bottle and the opposite larger diameter end of the sleeve is provided with a radially outwardly extending circumferential flange to be held captive against the outer end edge of the neck of the vacuum bottle behind the retaining flange of the mounting ring. The outer large diameter end of the sleeve defines an outwardly facing annular seat and a support arm has one end thereof pivotally supported from the handle of the mounting ring for oscillation about an axis disposed outwardly of the ring and normal to its center axis. The other end of the arm has a tapered stopper-type closure mounted thereon for swinging movement with the arm into and out of seated engagement with the outer end of the sleeve retained in position by the mounting ring. In addition, the handle includes an oscillatable actuator operatively connected with the arm upon which the stopper-type closure is mounted whereby the actuator may be manipulated at the handle to swing the stopper-type closure into and out of position closing the opening of the vacuum bottle.
