2. The blank of claim 1 , wherein the locking tab is joined to the main panel with a perforated connection.

3. The blank of claim 1 , wherein the locking tab defines at least one notch defining a notch depth measured relative to an edge of the locking tab.

4. The blank of claim 1 , wherein the locking opening is sized to receive and lockably engage the third tab subpanel of the locking tab upon assembly of the blank into a box.

5. The blank of claim 4 , wherein a the locking opening defines a closed shape.

6. The blank of claim 4 , wherein the locking tab extending from the first end of the first main panel, the blank further comprising a side panel extending from the fourth end of the first main panel, the bending tab extending from the side panel.

7. A locking device for a box, the locking device comprising:

a first panel defining a locking tab, the locking tab separable from the first panel and comprising a first tab subpanel, a second tab subpanel, and a third tab subpanel;

the first tab subpanel extending from the first panel, the second tab subpanel extending from the first tab subpanel, and the third tab subpanel extending from the second tab subpanel, the third tab subpanel of the locking tab configured to bend with respect to the second tab subpanel of the locking tab;

a second panel defining a locking opening, the locking opening sized to receive and capture the third tab subpanel of the locking tab, the third tab subpanel of the locking tab configured to engage an edge of the locking opening when the second tab subpanel and the third tab subpanel are in facing engagement and thereby configured to prevent movement of the locking tab with respect to the locking opening in an opening direction of the locking device;

a third panel positioned parallel to and offset towards the outside of the box from at least a portion of the second panel, the third panel and the portion of the second panel receiving the locking tab therebetween; and

a fourth panel positioned parallel to and offset towards the inside of the box from the portion of the second panel, each of the portion of the second panel, the third panel, and the fourth panel defining a front wall of the box, the front wall defining an opening between the third panel and the fourth panel, the opening sized to receive at least a portion of the locking tab therethrough.

8. The locking device of claim 7 , wherein engaged portions of the locking tab and the locking opening are hidden behind the locking tab relative to an observer outside of the locking device when the locking device is in an assembled position.

9. An assembled box comprising:

the locking device of claim 7 , wherein the assembled box further comprises:

a box top comprising the first panel, the first panel being a first main panel, the box top further comprising a first end panel extending from an end of the first main panel and offset towards the inside of the box from the fourth panel, at least one of the first main panel and the first end panel defining the locking tab, the second tab subpanel joined to the first tab subpanel, and the third tab subpanel joined to the second tab subpanel; and

a box bottom comprising the second panel, the second panel being a second main panel, the portion of the second panel being bent with respect to a main portion of the second panel.

10. The box of claim 9 , wherein the box top and the box bottom are formed from a single blank of material, the second panel being connected to the first panel.

11. The box of claim 9 , wherein the locking tab is angled with respect to the first main panel of the box top.

12. The box of claim 9 , wherein an end of the locking tab in a bent condition is narrower than a maximum width of the locking tab.

13. The box of claim 9 , wherein the box bottom defines a gap between the second panel and the third panel, the gap sized to receive the locking tab.

14. The box of claim 9 , wherein the locking opening is defined in a portion of the second panel angled with respect to a main portion of the second panel of the box bottom.

15. The box of claim 9 , wherein the locking tab is offset from a longitudinal axis of the box in a direction of a transverse axis of the box, the transverse axis being orthogonal to the longitudinal axis and parallel to at least one of the first main panel and the second main panel.

16. The box of claim 9 , wherein the third tab subpanel of the locking tab is bent with respect to the second tab subpanel of the locking tab, the locking tab being lockably engaged with the locking opening in a closed position of the box.

17. The box of claim 16 , wherein engaged portions of the locking tab and the locking opening are hidden behind the locking tab relative to an observer of an outside of the box in the closed position.
