A container formed from a blank and a method for constructing the container are described. The container includes a bottom wall, two end walls, each end wall including at least an end panel extending from an end edge of the bottom wall, and two side walls. The container further includes an upper reinforcing assembly at least partially extending from each end panel, and a side reinforcing assembly extending from opposing side edges of each end panel.

The present invention relates to a tray made of corrugated cardboard sheet material, and to blanks for preparing such a tray having a polygonal cross-section. Said blank comprises sidewalls, raised edges or portions of raised edges on two opposite sides of an upper portion, and a lower wall forming the bottom (36) of the case. Each raised edge or portion of raised edge includes at least one rounded portion (34), and the bottom includes perforated surface portions (35) which have a shape complementary to that of the rounded portions, which are arranged opposite the latter, and are arranged so as to fit into the rounded portions of the tray from below.

A method of forming a container from a blank of sheet material using a machine is provided. The blank includes a bottom panel, two side panels, two end panels, and a reinforcing panel assembly extending from a first side panel. The machine includes a hopper station, a corner post forming station, and a plunger station. The method includes rotating the reinforcing panel assembly upwardly toward the first side panel as the blank is transported from the hopper station to the corner post forming station, forming a corner wall and a reinforcing end tab by folding reinforcing panels about fold lines as the blank is transported through the corner post forming station, rotating the side panels and the end panels to be substantially perpendicular to the bottom panel by directing the blank through the plunger station, and coupling the reinforcing end tab to an end panel to form the container.

A machine for forming a container from a blank of sheet material is provided. The blank includes a reinforcing panel assembly for forming a reinforcing corner assembly. The machine includes a hopper station for storing the blank in a substantially flat configuration and a forming station for forming the blank into the container. The forming station includes an initial forming station that rotates a first portion of the reinforcing panel assembly with respect to a second portion of the reinforcing panel assembly, and a secondary forming station having male and female forming members with shapes corresponding to an interior shape and an exterior shape of the reinforcing corner assembly, respectively. The male and the female forming members are configured to form the reinforcing corner assembly by compressing together the first and second portions of the reinforcing panel assembly.

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 crate is described in the form of a flap-adhesively-bonded box composed of cardboard having a bottom (1) and a shell (2) protruding from the bottom (1), which forms reinforced upper longitudinal edge sections by way of edge flaps (8) folded inward between the shell corners. To provide advantageous design conditions, it is proposed that the shell (2) have, at least on one side of the shell corners, attachment flaps (10, 11, 26), which are each bent inward according to crease lines (12, 13, 27), which are outwardly offset in relation to the edge (14) of the reinforced longitudinal edge sections, by 90° and are adhesively bonded to the opposite side of the shell corner, and the bottom (1) be provided in the region of the shell corners with recesses (17) adapted to the outline shape of a catch attachment (15) formed by the attachment flaps (10, 11, 26).

A box and a blank or a set of blanks made from corrugated cardboard sheet comprising side walls, a top wall linked to at least two of said opposing side walls by a junction line or a folded edge, and a bottom wall forming the bottom of the box. The top wall comprises at least two convex portions comprising a projecting part, and the bottom comprises at least two perforated surface portions of complementary shape arranged to engage with the projecting parts of the box below. Each convex portion comprises an oblique triangular or substantially triangular panel belonging partly to a side wall or a folded edge.

An interlocking container formed from one piece of material, comprising, a base panel having a first, second, third, and forth edge; a first side foldably connected along a first edge to the first edge of the base panel, a second side foldably connected along a first edge to the second edge of the base panel, a third side is foldably connected along a first edge to the third edge of the base panel, a fourth side is foldably connected along the a edge to the fourth edge of the base panel, wherein when folded a container with interlocking tabs is formed.

A packaging assembly includes a packaging enclosure with a bottom closure that folds into a flap with a latch that locks into an opening on a face of the packaging enclosure. Upper faces of the packaging enclosure allow for juxtaposing and superposing a plurality of the packaging enclosures and providing space for air to circulate between them.

Packaging box for fruit, berries and vegetables comprising four side walls, a top side, and a bottom side. A portion of a side wall or the top side comprises a pour opening for tamper evident opening and pouring of content stored inside the packaging box. The pour opening comprises tear lines for opening the pour opening and means for accessing a tear grip of the opening portion.
