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.

A self-sealing container is formed from a blank comprising panels and end flaps connected along fold lines with the panels and the end flaps being foldable along the fold lines to form the container. The container includes a securing feature that seals the container in a closed position, with the securing feature providing a visual indication of opening if the container is opened from the closed position. After the container is opened, the securing feature provides a closure feature that allows the container to be closed.

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.

A food container includes a bottom panel and sidewalls pivotally connected to the bottom panel. A lid is pivotally connected to at least one sidewall to open and close the food container. A divider panel having at least one slot is inserted into any one of a plurality of slots in a spacer panel to create an adjustable compartment arrangement inside an internal cavity of the food container. The divider panel includes a groove that provides a recess between the divider panel and a sidewall of the food container that can accommodate a lip of the lid.

The invention provides a foldable box connection structure, a foldable box and a method of using the same. The foldable box connection structure comprises a first side plate, a second side plate, a first hinge, a first top plate, a seam cover plate and a positioning plate. The first hinge is used to connect the first top plate and the second side plate. The seam cover plate can be folded to cover the first hinge, and the seam cover plate and the positioning plate are configured to secure the first hinge. The foldable box includes the above-mentioned connection structure. In the present invention, the first top plate is hooked by the first hinge and the seam cover plate, and a second top plate is hooked by a third hinge, so that the foldable box has a fixed structure.
