A material handling device includes a base, a side, a support member, and a resilient biasing member. The side extends from the base and defines a device interior with the base. The support member is disposed within the device interior proximate the side. The support member includes a cam and is rotatable between a material handling device stacking position and a material handling device nesting position. The biasing member is coupled to the side and is configured to engage the cam and thereby urge the support member into one of the stacking and nesting positions. The resilient biasing member is also configured to effect a translation of the support member towards the side as the support member rotates from a position intermediate the stacking and nesting positions to the one of the stacking position and nesting positions.

1. A material handling device comprising: a base;a side extending from the base, the base and the side defining a device interior;a support member disposed within the device interior proximate the side, the support member including a cam and being rotatable between a material handling device stacking position and a material handling device nesting position; anda resilient biasing member coupled to the side and being configured to engage the cam and thereby urge the support member into one of the stacking and nesting positions, the resilient biasing member being further configured to effect a translation of the support member towards the side as the support member rotates from a position intermediate the stacking and nesting positions to the one of the stacking position and nesting positions. 2. The material handling device of claim 1, wherein the resilient biasing member has a neutral position and a deformed position displaced from the neutral position, the cam includes a cam surface configured to direct the biasing member from the neutral position towards the deformed position upon the rotation of the support member between the one of the stacking and nesting positions and the intermediate position, and the biasing member is configured to urge the support member from the intermediate position into the one of the stacking and nesting positions as the biasing member returns to the neutral position from the deformed position. 3. The material handling device of claim 2, wherein the resilient biasing member includes a hook member that is configured to engage the cam surface and thereby maintain the support member within the device interior as the support member rotates between the stacking position and the nesting position. 4. The material handling device of claim 2, wherein the side includes a guide channel, and the support member comprises a guide pin extending axially from an end thereof into the guide channel for sliding engagement therewith, the guide channel being configured to facilitate the translation of the support member towards the side as the support member rotates from the intermediate position towards one of the stacking and nesting positions. 5. The material handling device of claim 4, wherein the guide channel is further configured to direct the guide pin towards the base and thereby maintain the support member within the device interior as the support member rotates between the stacking position and the nesting position. 6. The material handling device of claim 4, wherein the guide channel is substantially arcuately-shaped and comprises a first end and a second end, the first end being disposed above the second end, and the guide pin is disposed to engage the first end of the guide channel when the support member is in the stacking position and to engage the second end when the support member is in the nesting position. 7. The material handling device of claim 1, wherein the support member further comprises a stacking platform that includes a pair of the ribs configured to capture therebetween a foot portion of a material handling device stacked on the material handling device to thereby limit lateral movement of the stacked material handling device relative to the material handling device when the support member is in the stacking position. 8. The material handling device of claim 7, wherein the stacking platform further includes a stabilization channel section for capturing therein an outwardly-extending rib of the stacked material handling device to further limit lateral movement of the stacked material handling device relative to the material handling device when the support member is in the stacking position. 9. The material handling device of claim 7, wherein the stacking platform further includes at least one stacking platform bumper positioned to support a portion of the stacked material handling device. 10. The material handling device of claim 7, wherein the stacking platform further includes a nesting channel section for capturing therein an outwardly-extending rib of a material handling device nested in the material handling device to thereby limit lateral movement of the nested material handling device relative to the material handling device when the support member is in the nesting position. 11. The material handling device of claim 10, wherein the side includes a nesting channel formed in an interior surface thereof, the nesting channel being substantially continuous with the nesting channel section when the support member is in the nesting position and is configured to capture the outwardly-extending rib therein. 12. The material handling device of claim 1, wherein the side comprises a shoulder disposed in the device interior for supporting the support member in the stacking position. 13. The material handling device of claim 1, wherein the support member further comprises a biasing channel formed therein for receiving the biasing member therein, and a portion of the cam extends across the biasing channel. 14. A material handling device lid comprising: a lid top including an upper surface, a lower surface, a latch opening extending between the upper and lower surfaces, and a flange coupled to the lower surface; anda resilient latch coupled to the lid top, the resilient latch being configured as a V-spring and comprising a first arm and a second arm, the first arm being coupled to the lid top and extending below the lid top away from the lower surface, and a second arm coupled to the first arm and extending towards the lid top and the lower surface, the second arm including at least one tang disposed proximate the flange and below the lower surface,wherein the second arm extends through the latch opening and terminates above the upper surface. 15. The material handling device lid of claim 14, wherein the latch opening includes a pair of opposite ends, the first arm is coupled to the lid top proximate a first of the opposite ends, and the flange is coupled to the lid top proximate a second of the opposite ends. 16. The material handling device lid of claim 15, wherein the first arm is integrally-molded with the lid top, the second arm is integrally-molded with the first arm, and the lid top and the first and second arms together comprise a unitary construction. 17. The material handling device lid of claim 16, wherein the lid top includes a rim extending around a circumference thereof, the rim and the first arm being configured to capture a side wall of a material handling device therebetween. 18. A material handling device assembly comprising: a material handling device comprising: a base;a side extending from the base, the base and the side defining a device interior;a support member disposed within the device interior proximate the side, the support member including a cam and being rotatable between a material handling device stacking position and a material handling device nesting position; anda resilient biasing member coupled to the side and being configured to engage the cam and thereby urge the support member into one of the stacking and nesting positions, the resilient biasing member being further configured to effect a translation of the support member towards the side as the support member rotates from a position intermediate the stacking and nesting positions to the one of the stacking position and nesting positions; anda material handling device lid configured to enclose the device interior, the material handling device lid comprising: a lid top including an upper surface, a lower surface, a latch opening extending between the upper and lower surfaces, and a flange coupled to the lower surface; anda resilient latch coupled to the lid top, the resilient latch being configured as a V-spring and comprising a first arm and a second arm, the first arm being coupled to the lid top and extending below the lid top away from the lower surface, and a second arm coupled to the first arm and extending towards the lid top and the lower surface, the second arm including at least one tang disposed proximate the flange and below the lower surface.
