ABSTRACT:
An adjustable box formed from a blank is disclosed. The box has two rectangular sides; a front panel and a back panel. The front panel and back panel each have two pairs of vertical fold lines on one side thereof, the front pair of vertical fold lines being on the opposite side from the back pair of vertical fold lines. Cooperating flaps including a tongue and groove arrangement are provided to close the box at the top and an automatic setup construction is provided to close the box at the bottom. As a result, the box can be folded along an inner fold line of the front and rear pair of vertical fold lines so that the bottom of the box has a first width. Alternatively, the box can be folded along an outer fold line of the front and rear pair of vertical fold lines so that the bottom of the box has a second width which is smaller than said first width. The cooperating flaps and the automatic setup construction must be adjustable so that once the box is closed at the top and at the bottom, and the box is folded along said inner fold line or said outer fold line, the box remains closed while folding the box between a wide configuration and a narrow configuration.
