1. A tubular metering device for insertion into a liquid product container for successively dispensing substantially uniform volumes of liquid from said device comprising:
- (a) a tubular body defining the exterior limits of said metering device, said tubular body having upper and lower end walls, said upper end wall having a dispensing opening located therein, said tubular body further having a vent opening located therein providing communication between the interior of said metering device and the interior or said container;
(b) an axially extending vertical wall dividing the upper portion of the interior of said metering device into a metering chamber sealed at the top by said upper end wall and a dispensing passage which communicates with the exterior of said device through said dispensing opening, said vertical wall terminating above said lower end wall of said metering device, leaving an undivided collecting chamber in the bottom portion of the interior of said metering device, said collecting chamber being in communication at its upper end with both said metering chamber and said dispensing passage;
(c) a transverse baffle projecting from said vertical wall intermediate said metering chamber and said collecting chamber, said baffle blocking off the lower end of said metering chamber, except for the portion thereof furthest removed form the dispensing passage, and serving to prevent flow of said liquid in either direction between the metering and the collecting chambers during the normal course of pouring a previously measured volume from the container.

Abstract
A metering device for successively dispensing uniform volumes of liquid from a container. The upper portion of the dispensing device is divided into a dispensing passage and a metering chamber by a vertical wall. The lower portion of the dispensing device is undivided forming a collecting chamber, the upper portion of which communicates with both the metering chamber and the dispensing passage. The metering chamber has axially spaced inlet and vent openings connected to the inner area of the liquid container. The metering chamber is partially segregated from the collecting chamber by a baffle protruding from the vertical wall. This baffle insures accurate operation of the dispensing device and reduces its necessary volume and length.
