Abstract: A corrugated board package formed from a blank of a kind having a single component to define a base, sides and top. The blank has a substantially square or rectangular base portion limited by fold lines and/or cuts or cutouts and four separate peripheral portions. The peripheral portions include an opposed pair of the peripheral portions being foldable to create first opposed side walls and subsequent to assembly being further folded to provide at least part of the top of the package, those portions of the peripheral portion to form the opposed side walls being extended at one end in a direction parallel to the fold line and/or cut or cutout connection to the base portion to define a flap which, either in a folded or unfolded condition, can be folded at right angles from the side wall to assume a position as part of the structure of an end wall normal to each opposed side wall with a projection or projections formed by part of the flap, whether a fold created periphery or otherwise, directed upwardly.
