ABSTRACT:
A device which may be used with a liquid metering and dispensing spout, includes a fluid receptacle having an upstanding annular side wall extending from a bottom wall, forming a given volume. The side wall has vent projection protruding therefrom. A volume determining member axially slideable in the receptacle has a tapered resilient side wall which is radially inwardly compressed by and forms a seal with the inner surface of the receptacle side wall to form a settable bottom wall for the receptacle. The side wall of the member engages the vent projection during its insertion to permit entrapped gas to escape between the side walls as the member is slid to a predetermined volume position.
