Assembly and system for connecting a closure to a syringe

摘要

An assembly for closing the discharge nozzle of a syringe which is pre-filled with a drug or medication. A syringe in combination with a connecting structure removably maintain and support the closure in an operative orientation, which facilitates the rotational attachment of the syringe and the closure when the closure is in mating engagement with the connecting structure. A subsequent removal of the syringe and connected closure from the container or other type of connecting structure is thereby facilitated. The need for an individual to directly handle or touch the closure during its attachment to the syringe is restricted or eliminated. The closure assembly preferably also includes a tamper evident structure which reduces the chances of tampering with the syringe in order to access its contents.

1. An assembly for closing a discharge port of a syringe, said assembly comprising:
at least one closure including a closed end and an open end, said one closure structured for rotational attachment to the syringe, a connecting structure including at least one connector mounted on said connecting structure and movable therewith, said one connector cooperatively structured with said one closure to define a rotationally restrictive connection there between, said rotationally restrictive connection comprising a substantially rotationally fixed positioning of said closed end and said one connector concurrent to rotation of said one closure and said one connector relative to the syringe, drive linkage connected to said connecting structure and operative to move said connecting structure and said one closure between a receiving position and a connecting position, said drive linkage disposed and structured to translate linear movement of said one closure and said one connector between said receiving and connecting positions to concurrent rotation of said one connector and said one closure relative to the syringe, and said drive linkage structured to rotate said one closure into said rotational attachment with the syringe, concurrent to disposition of said connecting structure and said one closure from said receiving position to said connecting position, upon a predetermined, substantially linear directed force applied, by the syringe, to said one closure, substantially co-axially to said drive linkage.
