ABSTRACT:
A stackable tray (11) functions with an adjacent stacked tray (12) to form a substantial enclosure (32) about an upper tray surface (15) formed by the tray sidewalls (17, 18) and tray endwall (21) and the lower surface (16') of an adjacently stacked tray (12). A break away separator (38) divides the enclosure (32) storage area into separate storage channels (40, 41) but may be broken away to form a larger channel area. Removable dividers (36) are selectively positioned in one of a plurality of spaced grooves (35) formed in the upper tray surface (15) to limit the depth of entry of stored items (34) into the substantial enclosure (32). Notches (28) and complimentary tabs (29) formed in lips (26) and grooves (27) of the sidewalls (17, 18) function to prevent sliding movement between adjacently stacked trays.
