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. The peripheral portions also include a second opposed pair of peripheral portions each being foldable to create part of the structure of the end wall normal to the first mentioned opposed side walls. The construction and arrangement of the package is such that in the assembled package the parallel flutes of the corrugated board run across the blank so as to be vertically extending in each side wall and in at least that part of each flap having the projection and further being such that there are openings formed in the base portion to allow the same to nest reproducibly on the projections of a like package, whether closed or not, to provide a nesting capability. The invention also consists of a blank for the package, the method of forming the package and apparatus for forming the package by the method using a sequence of forming zones.
