Abstract
Applicator assembly comprising a container for liquids having a bottom wall member, a cap member having means for detachably securing it over a discharge opening in the container. An upstanding wall and a bottom wall having an upstanding post member having an opening communicating with the interior of the container define a measuring chamber for a predetermined measured quantity of the liquid with a cylindrical wall portion of the cap member. An elongated tubular member is mounted in the opening in the post member extending downwardly into the container adjacent the lowest portion of the bottom wall member. A valve seat plate member is mounted at the open end of the cylindrical wall portion and has a wall portion terminating in a valve opening which is tapered towards the valve opening and functions as a funnel during discharge of contents to ensure complete transfer from the measuring chamber to a dispensing chamber above the measuring chamber. A flexible dauber having outlet holes is mounted over the outer end of the valve seat plate member and having a depending valve element biased solely by the dauber to normally seal the valve opening therein. The valve member is actuatable inwardly by pressure to overcome the bias of the dauber to permit flow of fluid from the measuring chamber to an enclosed dispensing chamber defined by dauber and valve seat plate member.
