DEFINITION

Classification: 239/364

(under subclass 340) Apparatus having means for simultaneously passing a pressure fluid from without the receptacle to the gas space above the liquid in the receptacle and to the pressure reducer at the outlet of the receptacle.

(1) Note. The pressure path to the receptacle is primarily for the purpose of relieving the vacuum which would occur therein if the container were hermetically sealed and liquid were siphoned or aspirated therefrom. The pressure on the liquid also inherently acts to force the liquid through the liquid outlet tube to the pressure reducer.
