Abstract: An inventory control system includes an inventory control probe, inventory control module, a docking station, a collar clip, and an inventory control collar used on a storage container. The inventory control collar includes a first conductive ring exposed on the top of the collar electrically connected to a memory and a second conductive ring exposed on the top of the collar and electrically connected to the memory. The inventory control probe includes a probe tip and a first pair of contact pins disposed on the probe tip at a predetermined distance apart such that the contacts concurrently contact the conductive rings of the inventory control collar. A probe body housing is connected at a first end to the probe tip, and a pair of data transfer terminal contacts are disposed on a bottom portion of the probe body housing. A handle is connected at a second end to the probe body housing.

Abstract: A polymeric inventory control collar locking ring for securing an inventory control collar around the cylindrical neck of a storage container comprising a circular disc with a central opening sized to fit around the neck of the storage container and a plurality of inwardly disposed flexible tabs spaced equally around the perimeter of the central opening. The tabs are formed integrally with the disc and extend radially inward into the central opening, having a distance of projection sufficient to engage the neck of said storage container.

Abstract: An inventory control collar incorporating a resident memory for use on a cylindrical neck of a storage container comprising an electrically insulative housing having a central opening sized to fit around the cylindrical neck of the storage container, and a circumferential groove located in the top of the housing. A first conductive ring inserted into the circumferential groove in the housing is electrically connected to the first terminal of the memory and a second conductive ring inserted into the circumferential groove in the housing is electrically connected to the second terminal of the memory. An electrically insulative retainer ring is inserted into the circumferential groove between the first and second rings. Data is conducted to and from the memory by electrically contacting the first and second conductive rings.
