Patent ID: 8771234

Claim:
An arrangement for expression of liquid into an opening of a liquid-receiving device by a practitioner, comprising: a support structure including at least one compartment for containing a liquid therein and further defining a plug-receiving cavity at the distal end thereof, and further including a distal body section which defines the plug-receiving cavity distally of a distal wall, the distal wall traversing the distal end of an empty compartment distally of the at least one liquid-containing compartment, and the arrangement further including a duct extending through the distal body section within which is affixed a needle that extends from the distal end of the at least one liquid-containing compartment through the empty compartment and through the duct into the plug-receiving cavity through which liquid is to be expressed, wherein the distal body section includes at least one aperture through a side wall thereof; a plunger activatable with respect to the at least one compartment for expression of the liquid from the compartment and into the liquid-receiving device; and a closure plug containing a transverse sealing membrane and having an exposed liquid receiving device connection section, wherein the closure plug is removably attached within the plug-receiving cavity via a non-threaded, releasable securement arrangement within the plug-receiving cavity and independent of the resealable membrane, wherein upon insertion of the closure plug into the plug-receiving cavity, the distal needle tip projects distally of the transverse sealing membrane of the closure plug, and wherein the distal body section of the support structure includes a cap collar affixed thereto at its distal end, the cap collar and distal body section adjacent thereto defining a ring seat wherein a plug-gripping ring is contained that includes an array of gripping sections extending radially inwardly a short distance to be engaged by side surfaces of the closure plug, comprising the securement arrangement, to establish a friction fit therewith when the closure plug is urged into the plug-receiving cavity.
