    摘要: A dry erase panel assembly for use as a teaching aid includes a first panel with a top edge, a bottom edge, a left edge, and a right edge. The first panel includes a writing section that is adapted to eraseably receive markings thereon. The panel assembly further includes a second panel with a top edge, a bottom edge, a left edge, a right edge, and a holding section. The second panel is secured to the first panel along the left edge and the right edge, whereby the holding section is spaced from the writing section to define a gap therebetween adapted to receive an information template.

    摘要: A connector for detachably securing together stacked molded plastic trays, which connector has a resilient tab projecting from a lower tray which slides into a slot in the tray above. Each slot has a rib rising from the tray bottom along one edge of the slot and a leaf spring integrally molded with the tray side wall opposite the rib. When the tab is inserted in the slot, the spring urges the tab against the rib and a lip on the tab hooks over the top edge of the rib.
