The object of the invention is a method for forming containers made of wood or wood fibre preferably for use with fruits and vegetables, comprising at least one base (5) and sides (6, 7), which extend with respect to the base (5), with the aid of first folding lines (3, 4). In a first step of the method, folding lines (3, 4) are defined on the laminar preform, whereon rectangular through holes (1) and non-through incisions (2) are die cut. Finally, the container is folded and the final assembly is performed. Likewise, an object of the invention are containers preferably for use with fruits and vegetables, for commercial or industrial use which are able to be obtained by the previous method.

A blank of foldable sheet material is provided. The blank includes a bottom panel, a first bottom side panel and a second opposing bottom side panel extending from opposing side edges of the bottom panel, and a front panel extending from a front edge of the bottom panel. The front panel includes opposing side edges. The blank also includes a first and a second diagonal panel extending from a front edge of the first and second bottom side panels, respectively, and a third and a fourth diagonal panel extending from each side edge of the front panel. The third and fourth diagonal panels have a length greater than a length of the first and second diagonal panels. The blank includes a first and a second corner panel, wherein the first corner panel is hingedly connected to the first and third diagonal panels and the second corner panel is hingedly connected to the second and fourth diagonal panels.

A blank of sheet material for forming a polygonal container, the blank including, a bottom panel, two opposing end panels, each end panel extending from an end edge of the bottom panel, two opposing outer side panels, each outer side panel extending from a side edge of the bottom panel, and an inner side panel extending from each top edge of one outer side panel of the two outer side panels and an outer side panel extending from each top edge of the one of the inner side panels, wherein each inner side panel includes a central portion, a corner portion extending from each side of the central portion, and an inner end portion extending from a side of each of the corner portions.

A tray made from cardboard sheet material comprising a rectangular base and a ring of side walls, including two opposed first side walls symmetric with respect to a transverse axes of the tray and two second walls, including a second rear wall and a second front wall of lesser height than the other walls.

A blank of sheet material for forming a polygonal container is provided. The blank includes a bottom panel, two opposing side panels, two opposing end panels, and a reinforcing panel assembly extending from a first side edge of a first end panel of the two end panels. The reinforcing panel assembly includes a corner panel extending from the first side edge of the first end panel, a first reinforcing side panel extending from a side edge of the corner panel, a second reinforcing side panel extending from a side edge of the first reinforcing side panel, a reinforcing corner panel extending from a side edge of the second reinforcing side panel, and an inner end panel extending from a side edge of the reinforcing corner panel. The corner panel and the reinforcing corner panel are configured, upon articulation of the blank, to be positioned into face-to-face relationship to form a corner wall of the container extending from a side edge of an end wall of the container to an end edge of a side wall of the container.

A display tray formed of a continuous blank having a plurality of hingedly coupled panels and sub-panels including a first sidewall, defined at least partially by a first panel, a front wall, defined by at least partially by a second panel, hingedly attached to the first panel sidewall, a second sidewall, defined at least partially by the first panel sidewall, and a rear wall defined at least partially by a third panel hingedly attached to the first panel for adjoining the display tray to a second display tray.

A display tray system including a first tray defining an outer perimeter of the display tray system, a second tray having at least three outer walls defining an outer perimeter of the display tray system, a first corner having a first height at a junction of two of the at least three outer walls, a second corner having a height equal to the first corner at a junction of two of the at least three outer walls, a joining wall defining an inner border with the first tray, a third corner at a junction of the joining wall and one of the at least three outer walls, a fourth corner at a junction of the joining wall and one of the at least three outer walls, and a joining member coupled to the joining wall of the first tray and coupled to the joining wall of the second tray to couple the first and second trays together and provide vertical support.

A container includes a plurality of panels integrally arranged with respect to each other and with respect to a set of orthogonal x, y and z axes, the plurality of panels being foldable to create the container. The plurality of panels include a first panel disposed parallel to the z-axis, the first panel having a first side portion, a second side portion, and a display portion disposed between the first and second side portions, the first and second side portions and the display portion being coplanar and bordering at least a portion of a product display opening. The first panel further includes a first relief feature disposed between the display portion and the first side portion, and a second relief feature disposed between the display portion and the second side portion, wherein the at least a portion of the product display opening and the first and second relief features are formed by an absence of material of the first panel.

A locking receiving portion is defined by a first inclined line extending toward a third panel side on a first panel from a branching point on a fold line between the first panel and a second panel, a second inclined line extending toward the third panel side on the second panel from the branching point, and a cut portion extending between a distal end of the first inclined line and a distal end of the second inclined line. The locking receiving portion extends in an inclined manner between the first panel and the second panel in an assembled state. A locking portion is formed on the third panel, and configured to be locked to a cut portion side of the locking receiving portion in an assembled state.
