A blank can include a first end panel; a first main panel joined to and extending from the first end panel; a second main panel connected to the first main panel; a second end panel joined to and extending from the second main panel; an inside end panel connected to the second main panel; and a locking tab extending from and separable from the first main panel, passable through a first opening defined between the second end panel and the inside end panel, and engageable with a locking opening separate from the first opening and defined in the blank.

A blank can include a main panel and a locking tab extending from and separable from the main panel and including a first tab subpanel, a second tab subpanel, and a third tab subpanel; the first tab subpanel extending from the main panel, the second tab subpanel extending from the first tab subpanel and joined to the first tab subpanel at a first bend line, and the third tab subpanel extending from the second tab subpanel and joined to the second tab subpanel at a second bend line.

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.

A leak proof container and a method of forming the container from a blank. The blank includes a bottom panel, first and second side panels connected to the bottom panel at opposing lateral edges, and first and second end portions located at opposing longitudinal ends of the blank. Each end portion includes an inner end panel connected to the bottom panel, an outer end panel connected to the inner end panel, and first and second corner panels, each corner panel having an edge connected to a respective one of the first and second side panels and having an edge connected to the inner end panel. First and second locking tabs are defined in the outer end panel, each locking tab being defined by a lateral separation line located longitudinally inward from an outer longitudinal edge of the outer end panel and extending laterally to define a free tab end.

A paperboard food container includes a paperboard receptacle and a paperboard closure. The paperboard receptacle encloses, in an assembled state, a three-dimensional space in which a food product may be disposed and has an opening through which the food product enters the space. The paperboard closure is disposed across the opening, and includes first and second surfaces, one of the first and second surfaces, one of which has a tamper-evident region of weakness that may be irreversibly split to open the closure.
