Abstract: A method of using a box can include obtaining the box, the box comprising a box top and a box bottom, the box top comprising a first main panel and a first end panel, at least one of the first main panel and the first end panel defining a locking tab separable from the box top; the box bottom comprising a second main panel and a second end panel, the second end panel defining a locking opening, a lateral width of the locking tab at an ear thereof being greater than-and at a neck thereof being less than-a lateral width of the locking opening; inserting the locking tab into a gap defined at least in part by the second end panel, thereby hiding a portion of the locking tab behind the second end panel; and engaging the locking tab with the locking opening.

Abstract: A box can include a box top including a first panel and a locking tab separably joined to the first panel, the locking tab comprising first and second tab subpanels; and a box bottom including a second panel defining a locking opening, a lateral width of the locking tab at an ear thereof being greater than-and at a neck thereof being less than-a lateral width of the locking opening, the locking opening sized to receive and capture the locking tab, the locking tab configured to engage an edge of the locking opening and thereby configured to prevent movement of the locking tab with respect to the locking opening in an opening direction of the locking tab; wherein engaged portions of the locking tab and the locking opening are hidden to an observer outside of the box when the box is in an assembled position.

Abstract: A locking device for a box includes a first panel defining a locking tab separable from the first panel and comprising a first tab subpanel and a second tab subpanel; the first tab subpanel extending from the first panel and the second tab subpanel extending from the first tab subpanel, the second tab subpanel including a neck and an ear, the ear extending from the neck in a lateral direction of the locking tab; and a second panel defining a locking opening, the locking opening sized to receive and capture the locking tab, the locking tab configured to engage an edge of the locking opening and thereby configured to prevent movement of the locking tab with respect to the locking opening in an opening direction of the locking device.

Abstract: A method comprising obtaining a box comprising a box top defining a locking tab separable from the box top and comprising first, second, and third tab subpanels; the locking tab and the first tab subpanel thereof extending from at least one of a first main panel and a first end panel of the box, the second tab subpanel extending from and joined to the first tab subpanel, and the third tab subpanel extending from and joined to the second tab subpanel; and a box bottom comprising a second main panel; a second end panel joined thereto; and a tab connected to the second main panel and defining a locking opening; bending the third tab subpanel with respect to the second tab subpanel; inserting the locking tab into a gap defined at least in part by the second end panel; and engaging the locking tab with the locking opening.
