ABSTRACT:
A sample case assembly has a pair of open ended containers each of which is supported by one section of a two-section wheeled base member or dolly. The dolly sections are pivotally joined together and with their respective display enclosures are pivoted horizontally between open and closed positions. The containers may be hinged together on one side to form sample cases and detachably connected to the dolly. A plurality of sample cases may be stacked one above the other on the dolly and aligned to pivot open simultaneously with opening of the dolly sections. A transport handle is attached to the uppermost case to facilitate mobility of the assembly.
