Container closure, container assembly and method for utilizing the same

A container assembly, comprising:

• a container closure including an end wall connected to a side wall, wherein the end wall includes a central portion and an outer perimeter portion, wherein the side wall includes a proximal end and a distal end, wherein the proximal end of the side wall is connected to and extends away from the outer perimeter portion of the end wall, wherein the end wall includes an inner surface and an outer surface, wherein the side wall includes an inner surface and an outer surface;
• and
• a container connected to the container closure, wherein the container includes an end wall and a side wall, wherein the end wall of the container includes a central portion and an outer perimeter portion, wherein the side wall of the container includes a proximal end and a distal end, wherein the proximal end of the side wall of the container is connected to and extends away from the outer perimeter portion of the end wall of the container, wherein an inner surface of the end wall of the container and an inner surface of the side wall of the container form a fluid reservoir, wherein access to the fluid reservoir is permitted by an opening formed by a distal end of the side wall of the container;
• wherein the outer surface of the end wall of the container closure defines a syringe-engaging portion, wherein the container closure includes a fluid-drawing member that extends axially away from and is integral with the inner surface of the end wall of the container closure, wherein the fluid-drawing member includes a proximal end and a distal end, wherein a fluid-flow passage extends through the fluid-drawing member between the proximal end of the fluid-drawing member and the distal end of the fluid-drawing member, and wherein the proximal end of the fluid-drawing member is connected to and extends away from the inner surface of the end wall of the container closure, and wherein the fluid-drawing member extends through the opening and into the fluid reservoir, and wherein a distal end of the fluid-drawing member is arranged proximate the inner surface of the end wall of the container, wherein the container closure further includes a disk-shaped member including a slit, wherein the disk-shaped member is disposed upon and supported by one or more of a shoulder surface and an axial wall surface defining the syringe-engaging portion.
