ABSTRACT:
A container for dispensing predetermined quantities of liquid comprises a first or primary container having a bottom portion, sidewall portion and open-ended neck portion. A second container comprising an elongated tubular substantially within the first container depending from the neck portion thereof. A third container disposed completely within the first container is integral with and disposed substantially concentrically around the second container. The third container comprises sidewall, bottom and top portions which together form a fluid sealing enclosure, the top and bottom portions being integral with and supported by the outer surface of the second container. The third container, communicates with the primary container by means of an opening provided in the upper portion to its sidewall portion serving as a liquid inlet. A second tubular member of relatively small diameter connects the bottom portion of the second container with the portion of the third container. In normal use, tipping of the container to pouring position results in the discharge of liquid present in the second container. Simultaneously therewith, liquid from the primary container enters the third container through the liquid inlet opening. Restoration of the container to its normal upright position causes liquid in the third container to enter the second container through the tubular member connecting the bottom portions of these containers.
