Abstract: An annular attachment device is provided that is adapted to engage the threads of a threaded container and provide a connection point for the threaded container. In such an arrangement, the threads of a container may be placed through a center aperture in the attachment device. By threading a lid onto the container, the annular attachment device may be trapped between the container and its lid. An aperture or hook on an outer surface of the annular attachment device allows the device and a supported container to be tethered to a desired location.
