As shown in FIG. 1 and FIG. 1A the tote system may include a number of bins of different sizes and shapes. The bins are typically secured within the tote by a tab system on the side walls. As shown in FIG. 1, a tote 10 is provided with side walls 12 that may contain, a half-sized bin insert 22, a quarter-size bin insert 26 and two eighth-size bin inserts 28. The bin inserts may optionally include handles 24. The tote 10 may include a reinforcing rim 30 and a secondary rim 30a formed on the upper portion of sidewalls 12 and a lower rim 34. Also included on sidewalls 12 are vertical tote reinforcements 36 and rim reinforcements 32 as well as a lower rim 34. The various bin inserts 22, 26, 28 may be used in any combination based on the needs of the facility using the totes.

The bin insert retaining system is shown in FIG. 1A, first and second tote sidewalls 12 include recesses for retaining bin inserts within the tote. The bin insert may include any number of recesses in each side wall. Preferably, the recesses 50, 52 are paired so each pair of recesses receives a pair of inserts on a bin 28. A second type of recess 64 may be provided for the insertion of divider walls (as shown in FIG. 6). Bin insert 28 includes side walls 28a, 28b, 28c, 28d and sidewalls 28a and 28c may include stack ribs 54. Stack ribs 54 are provided to inhibit the jamming of empty bin inserts 28 when stacked. The bin insert 28 also includes at least one retaining tab 50, 52 each having a spacer 84 that displaces tab 50, 52 from sidewall 28d of bin insert 28. While tabs 50, 52 are shown turning to opposite sides they tab 52 may be of any suitable configuration, such as toward the exterior of the bin insert, toward the interior of the bin insert or spacer 84 may be located toward the center of tabs 50, 52 so that no apparent left or right turn is present. Tabs 50, 52 are received in slots 60, 62. Each slot 60 includes a front wall 60a, side wall 60c, back wall 60d and distal wall 60b. The walls 60a, 60b, 60c and 60d enclose slot 60, which receives the tab 50 while spacer 84 fits between front wall 60a and side wall 60c. Similarly, as shown walls 62a, 62b, 62c and 62d are formed in tote wall 12 to receive tab 52. A second configuration for a slot 64 in sidewall 12a is shown in FIG. 1A in which the groove 64 is defined by two front walls 60a, side walls 60b, 60c and a back wall 60d. Reinforcing rim 30 and secondary rim 30a formed on the upper portion of sidewalls 12 and rim reinforcements 32 provide a stiff and rugged tote for the bins.
