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.

An unwinding unit (400) for unwinding a strip (S) of heat sealing material for quadrangular machines (1) comprises a casing (401) adapted to be mounted on a quadrangular machine (1) and a puller (402) operatively associated with the casing (401) and configured to pull the strip (S) relative to the casing (401) along a feed path (P) and in a feed direction (V). A diverter (407) is configured to divert the strip (S) between an initial, preferably horizontal, stretch (P1) of the feed path and a final, substantially vertical stretch (P2) of the feed path, defining a curved, connecting stretch (P3) between the initial stretch and the final stretch. A deformer (413) operatively associated with the casing (401) are configured to make on the strip (5) an extended crease line (414) running along the strip itself starting from the curved stretch (P3) or downstream of the curved stretch (P3), in the feed direction (V) of the strip (S).

An apparatus to display packaged products that includes a base that includes a bottom segment, at least two supporting segments, and a top segment, the top segment provided with a plurality of apertures and supported at least in part by the at least two supporting segments such that the bottom segment and the top segment are generally parallel; and at least two side portions, at least one of said side portions comprising a support column, the at least two side portions being generally perpendicular to the bottom segment and the top segment. Methods of assembling the apparatus are also provided.

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 cardboard casket includes a top piece and a bottom piece. The top piece is formed by making a single press die cut in a reinforced core cardboard panel, including cutting the reinforced core cardboard panel to form the top piece and forming seams in the top piece. The bottom piece is formed by making another single press die cut in another reinforced core cardboard panel, including cutting the other reinforced core cardboard panel to form the bottom piece and forming seams in the bottom piece. Cutting the top and bottom pieces includes cutting through a first layer, a reinforced core, and a second layer of the reinforced core cardboard panels. Forming seams in the top and bottom pieces includes deforming the first layer in the seams, deforming a majority of the reinforced core in the seams, and leaving the second layer in the seam uncut.

A shaped article, a method for making it, and its use. The shaped article is formed from flat fiber material and has a bottom (2), a body (4), and an opening, which is surrounded by a circumferential flange (6). The shaped article (1) comprises a flange stabilizer (10) attached to the second flat side (18) of the flange (6) facing the bottom (2). The flange stabilizer (10) is disc-shaped and has an inner contour (12) corresponding to the desired cross-sectional shape of the shaped article (1) in the region of the opening and can be slipped over the body (4) in the region of the bottom (2) and up to the flange (6). The flat sides (16, 18) of the flange stabilizer (10) extend essentially parallel to the flange (6), defining and stabilizing the cross-sectional shape of the body (4) in the region of the opening and the flange.

An apparatus for forming a container from a blank is provided. The apparatus includes a blank feeder assembly, and a compression assembly including a mandrel assembly, an upper folding arm assembly including a plurality of folding arms moveable between a first position and a second position, a compression plate, and a rollover arm assembly.

A container for foodstuffs includes a containment body having a polygonal bottom wall and perimeter side walls connected to each other and to the polygonal bottom wall so as to define a food containment volume open at the top at an upper opening. At least two side flaps and one upper flap extend from each perimeter side wall. Each side flap is connected to the respective side wall through a respective side folding line and abuts against and is bonded to a respective adjacent side flap, defining a supporting element outside the containment volume. Each upper flap is connected to the respective side wall through a respective first upper folding line along which it is folded away from the containment volume so as to define an edge portion of the container suitable to receive a closure element.
