Abstract: An organizer tray which is insertable within the upper portion of an empty container such as a five gallon bucket for use in organizing tools and like articles typically transported by craftsmen in empty buckets. The organizer tray is provided with bottom open, arcuately shaped channels which enable the tray to be emplaced over the upper rim portion of the container for easy access to the top open storage compartments. The organizer tray can conveniently be stacked onto a tray of identical design in a stable, slightly spaced configuration. For this purpose, the tray includes a radially inwardly extending protuberance which is engagable by a spacing finger provided on a superiorly mounted tray.
