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.

Abstract: A needle shield comprising an elongated tubular housing having a central bore, means at one end for detachably mounting the shield to the hub of a syringe assembly, and means defining an elongated generally cylindrical chamber in the end of the housing opposite the mounting means. An inner end communicates with the bore and an insert made of resilient impermeable pierceable material is snugly supported in the chamber. The chamber is of a diameter slightly greater than the diameter of the insert and includes a tapered wall portion at the inner end and has a section of smaller diameter than the insert to provide a tight generally hermetic sealing relation therewith. The wall of the chamber opposite the inner end is deformable to permit ease of assembly and deformation after insertion of the plug to firmly seat the plug in the chamber.
