A method of preparing a fluid-filled container for threadable attachment thereto of a syringe using a container adapter and a syringe adapter, comprising:
- placing a radial extension of a syringe adapter against a collar on a neck opening of a fluid-filled container, the syringe adapter comprising a sidewall extending between a proximal end and a distal end opposite the proximal end, the sidewall having an interior surface defining a chamber, the sidewall defining a proximal-end opening and a distal-end opening at a terminal end of the proximal end and the distal end, respectively, the proximal end configured to be threadably connected to a syringe tip at a distal end of a syringe, thereby causing the distal end of the syringe adapter to enter an interior of the fluid-filled container through a membrane disposed across the neck opening;
- securely holding the syringe adapter within an inner void of a container adapter while simultaneously securely holding the syringe adapter to the container, the container adapter comprising an upper surface and a container adapter sidewall, the container adapter sidewall formed as being attached, at an upper edge, to an outer edge of the upper surface and simultaneously attached, at a bottom edge, to a lip extending inward from the bottom edge, the lip configured for placement under an edge of the collar, the upper surface configured to separate along a bisection through a center thereof upon flexing a flex point of the container adapter sidewall, the center having a multi-sided cut-out portion therein, the multi-sided cut-out portion configured to receive and, upon closing the bisected upper surface, to close around a corresponding-shaped multi-sided portion of an exterior of the syringe adapter, wherein the securely holding further comprises:
- closing the bisected upper surface around the corresponding multi-sided portion of the exterior of the syringe adapter, while the radial extension remains placed against the collar, by inserting a loose end of a strap through an opening in an extension until the upper surface is no longer separated along the bisection, wherein the strap extends from an area at a first end of the container adapter sidewall and the extension is formed at an area at a second and opposite end of the container adapter sidewall;
- and
- continuing the inserting of the loose end until at least one protrusion extending therefrom passes through the opening, thereby preventing the strap from being backed out of the opening;
- and
- threadably connecting a cap to the proximal end of the syringe adapter, thereby closing off the proximal-end opening into the chamber of the syringe adapter, the cap configured to threadably disconnect from the proximal end of the syringe adapter for threadably connecting the syringe tip thereto to thereby open the proximal-end opening into the chamber and thereby open a fluid path connecting a barrel of the syringe, the chamber of the syringe adapter, and through the distal-end opening of the syringe adapter, the interior of the fluid-filled container.
