Assembly of modular containers for handling, transporting and storing microscope specimen slides

The present invention pertains to an assembly of modular containers for the handling, transporting and storing of microscope specimen glass slides. An assembly of stacked modular containers for handling, transporting and storing microscope specimen slides is described. The side walls of the rectangular-shaped containers have slide interconnections so that the containers may be longitudinally slid relative to one another. A releasable locking arrangement is provided on the extension of one of the other container walls to prevent unwarranted longitudinal sliding movement of the containers and to retain them in a secured stack formation. The extension of the container wall is made flexible to enable manual disengagement of locking members on the extension to thereby allow the sliding of containers for insertion or removal of slides into and from the containers.
