Abstract: A bingo box (10) comprises substantially identical first and second relatively rigid containers (12, 14) each having a hinged angled panel (38) for providing a working angled surface (36) with clamps (48) at one end thereof. The first container includes a right hinge means at an intersection of its tapered right edge wall (20) and base sidewall (16) and the second container including a left hinge means at an intersection of its tapered left edge wall and base sidewall. The right and left complementary hinge elements are selectively engagable with one another for allowing the first and second containers to rotate relative to one another between a carrying configuration in which the base sidewalls are adjacent one another and a working configuration in which the base and work sidewalls (18) are approximately coplanar to one another. Storage spaces can be accessed via the hinged angled panels when the containers are in both the carrying configuration and the working configuration.
