发明名称 Betting tray
摘要 An annular tray having numbered compartments, downward and inward sloping bottom on no inner side surrounds a separate central cylindrical container having vertical sides. When assembled, the sides of the central container form an inner side to the numbered compartments of the annular tray such that objects such as betting chips or coins placed in the numbered compartments are restrained from falling out. When the annular tray is raised while leaving the cylindrical container resting on the original surface, the objects in the compartments are no longer restrained by the walls of the cylindrical container, but instead, fall downward and inward into the cylindrical container from when they are readily retrieved.
