Abstract

A one-piece carton of the type having a lid portion hingedly connected thereto wherein the lid portion is adapted to fit over the container portion by making the open end of the container portion smaller than the open end of the lid while the closed upper end of the lid portion and the bottom end of the container portion are substantially the same dimensions. The open end of the container portion is made smaller than the open end of the lid portion by ensuring that upon assembly of the container portion the side walls are toed inwardly. The side walls of the container portion are maintained in the inwardly toed position by articulated panels which are connected to adjacent side walls of the container portion and the lid portion. The articulated panels are creased along angularly inclined fold lines which extend from the base of the side walls of the container portion and the lid portion and intersect one another, the angle formed between the back wall and the fold line which extends from the lid portion whereby the side walls of the container portion are toed inwardly in a direction away from the bottom wall. Preferably the lid portion has a height which is less than 50 per cent of the height of the container portion.

Claims

1. In a one-piece carton of the type having a bottom wall, a front wall, a back wall and a pair of oppositely disposed side walls defining a container portion having an open upper end and a lid portion hingedly connected to the back wall of the container portion and having a top wall, a front wall aNd a pair of oppositely disposed side walls defining an open lower end, the side walls of the said container portion being folded along the fold lines which are aligned with the fold lines along which the side walls of the lid portion are folded, the improvement wherein said front wall of said container portion has a fold-over flap at its upper edge and said side walls of said container portion each have a front edge and a flap panel hingedly connected to and projecting connected from said front edge and folded to a position inwardly of said front wall and underlying said foldover flap when the container portion is erected, said flaps each having an upper edge which is upwardly inclined in a direction away from its connection with said side wall panels of extending container portion whereby said upper edge of said flap portion is engaged by said fold-over flap of said front wall to retain said side walls of said container portion in said inwardly inclined position.

2. A unitary nestable blank for forming a carton comprising a lid front wall fold-over flap, a lid front wall, a lid top wall, a container back wall, a container bottom wall, a container front wall and a container front wall fold-over flap hindedly connected along longitudinally extending spaced parallel hinge lines, a pair of container side wall panels hingedly connected to said bottom wall along parallel transverse hinge lines, a pair of articulated panels hingedly connected to said back wall along parallel transverse hinge lines and a pair of lid side walls hingedly connected to said lid portion along parallel transverse hinge lines, said parallel transverse hinge lines being aligned with one another, said articulated panels being foldable along weakened fold lines extending inwardly thereof from the intersections of the transverse and longitudinal hinge lines thereof, said articulated panel means being connected to said side walls of said lid and said container portion along longitudinally extending hinge lines, first flap panel means hingedly connected along the longitudinally extending hinge lines to said side walls of said container portion and projecting outwardly therefrom and second flap panel means hingedly connected along longitudinally extending hinge lines to said side walls of said lid portion and projecting outwardly therefrom, said flap panels, said side walls of said container portion, said articulated panel means and said side walls of said lid portion having a single cut nestable edge extending continuously thereof, the portion of the nestable edge extending from the hinge line connecting the flap panels to the side walls of the container portion being angularly inclined outwardly in a direction away from said hinge line and the portion of the nestable edge extending inwardly from the end of the flap panels which are connected to the side walls of the container portion and the adjacent side wall being angularly inclined inwardly in a direction towards the outer end of the flap panel equal to the outward angle of inclination of the nesting edge of the first mentioned flap panel.
