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.

Abstract:

A single barrel two compartment assembly for medicaments comprising an elongated cylindrical hollow barrel having a normally sealed discharge end, a bypass plunger made of a pliable resilient material having a forward section of a diameter slightly greater than the diameter of the barrel, means defining a seat in the bypass plunger, a plunger rod having a tip engageable in said seat for actuating said bypass plunger axially in said barrel and seal means for sealing the open end of the said barrel remote from said discharge end, said bypass plunger normally dividing said barrel into a first compartment to one side of the bypass plunger for a powder medicament and a diluent compartment on the opposite side of said bypass plunger, actuation of said bypass plunger in one direction creating internal diluent pressure whereby said diluent bypasses the periphery of said plunger to mix with said powder medicament.
