Abstract:
A needle and cap assembly for attaching to a hypodermic syringe body includes a needle mounting structure, a needle, and a cap slideably mounted on the needle mounting structure. The needle mounting structure includes a hub, arcuate bands making a sliding fit with an interior surface of the cap, and spokes connecting the bands to the hub. Each band has a profiled tail end including an indent, which cooperates with an axial guide rail on the interior surface of the cap, to allow the cap to be selectively rotated between a first position, in which the cap is retained in an extended position covering the needle, and a second position, in which the cap may be moved in guided axial motion to a retracted position exposing the needle.
