Abstract: A disk-like container having a cylindrical sidewall is retained and released from a receptacle formed by a partial cylindrical back wall adapted to contact the cylindrical sidewall of the container. A first portion of the back wall extends circumferentially less than 180 degrees around the cylindrical sidewall of the container. A second portion of the back wall extends from the first portion, and cumulatively with the first portion extends circumferentially to greater than 180 degrees around the cylindrical sidewall of the container. A release tab formed by the second portion of the back wall deflects to move the second portion outward away from the cylindrical sidewall of the container to permit the container to be inserted into and removed from the receptacle. A plurality of the receptacles are formed in a single clip tray, and the clip trays may be oriented and positioned singularly or in multiple assemblies.
