Abstract
The present invention is a mechanical contrivance integrated into the closure of a sharps collector. It is intended to allow for the safe removal and disposal of a used pen needle from a pen syringe device. The pen syringe, with the used pen needle attached, is inserted into the specially designed port of the present invention. The pen syringe is then rotated counterclockwise about its longitudinal axis. The pen needle itself is constrained by at least one tooth, which only allows the pen needle one degree of freedom (linear displacement along its longitudinal axis). These conditions cause the pen needle to be unthreaded from the pen syringe, such that when the pen syringe is withdrawn from the port, a tang then blocks the pen needle from being withdrawn with the pen syringe, and the used pen needle falls into the sharps collector without the use of a secondary operation.
