Abstract
A cleaning device for LADs, and other such threaded devices, comprising a cap and a cleaning agent. The cap comprises a casing having an opening to an interior cavity. A threaded coupling mechanism is located on the inner surface of the casing proximate the opening. The coupling mechanism has retention features that provide localized pressure points on the threads of the LAD to accommodate thread variance and reduce the chance of premature disengagement.
