The first elongate flange part section is arranged to the respective wall part, the third elongate flange part section is connected parallel and along an elongate edge to the second elongate flange part section, the third elongate flange part section is adhered to the outside of the respective wall part, and the second flange part section is double folded against the first flange part section.

The invention relates to a container. In particular the invention relates to a container for receiving a food product which container is formed from a folded blank. The body of the container is formed from panels of the container blank and at least one flange section is provided at an edge of an opening of the container body. The flange section comprises two overlapping flange panels of the container blank, which are bonded together to maintain the shape of the container body.

A container comprising a bottom panel defining a base of the container, and a plurality of side walls extending from the bottom panel and defining an interior area of the container, wherein the plurality of side walls include at least opposing first and second side walls. A first flange structure is connected to each of the first and second side walls along respective fold lines at an upper edge of the container. Each first flange structure straddles a respective side wall and comprises an inner flange portion extending over the interior area of the container, and an outer flange portion, coplanar with the inner flange portion, extending away from the interior of the container, wherein the outer flange portion is defined by one or more tabs.

A method for producing packaging comprises providing the shell part that defines an opening, a cavity at least partially formed by a bottom wall and side walls, and a continuously circumferential lower contact surface at a constant height around the opening of the cavity and providing a collar including the circumferential edge flange. At least one bottom tool is structured to comprise aa lower contact surface and a cavity configured to receive the shell part. At least one top tool is structured to comprise an upper contact surface. The shell part is inserted into the cavity of the at least one bottom tool and the collar is placed on the lower contact surface. A barrier film is placed over the edge flange and pressed to form a tray that is filled with goods. A sealing film is then pressed against the barrier film to seal the goods within the tray.

The object of the invention is a product package and a method for producing the product package. The product package comprises a recess (1a) for the product to be packed, the recess being provided with a base and with walls in connection with the base, in which case the frame part (2) of the recess (1a) has been formed by means of folds from recyclable fiber material and the aforementioned recess (1a) is lined on the inside with a separate inner lining (3), which is removable from the aforementioned frame part. The top edges of the side walls and end walls of the frame part and also the top edges of the corner parts (10) form the top edge of the recess, which top edge is arranged to function as a fastening surface for the inner lining (3), which inner lining (3) is adapted to comprise an edge section (4) extending over the top edge (5a) of the recess (1a).

A container configured for at least partially containing fresh meat can include a base panel above which an interior space of the container is defined. The base panel can be configured to support fresh meat, and elongate interior passageways can be at least partially defined by the base panel. Openings can be respectively open to the plurality of interior passageways for allowing fluid from the fresh meat in the interior space of the container to flow into the interior passageways. The container can be configured to at least partially retain the fluid in the interior passageways, including opposite end sections of at least some of the interior passageways being closed to at least partially define compartments for receiving and retaining the fluid.

A cardboard tray folded from an unfolded sheet of cardboard includes: a bottom wall with a circumferential edge formed out of an even number of straight edges; wall parts each arranged to a straight edge of the bottom wall; and first flange parts alternately arranged to subsequent wall parts along the circumferential edge. The first flange parts include at least a first, a second, and a third elongate flange part section, which are connected parallel and along an elongate edge to each other. The first elongate flange part section is arranged to the respective wall part, the third elongate flange part section is connected parallel and along an elongate edge to the second elongate flange part section, the third elongate flange part section is adhered to the outside of the respective wall part, and the second flange part section is double folded against the first flange part section.

A product package is disclosed having e a frame part with a recess for a product and a removable inner lining. The frame part includes a base and connected side walls, end walls, and corner parts. The side and end walls each include a first part folded from the base and a second part folded from the first part toward the base. The side and end wall second parts include a cut edge which is fitted into the recess of the package, and the inner lining is fitted on top of the second parts so as to enclose the cut edges. The inner lining also includes an edge section which forms an edge flange extending over top edges of the frame part and a package lid which is arranged to be fastened to said flange.

A stackable box has side walls and end walls upstanding from a base, the box being formed from a single sheet of material cut and creased to provide, between each end of each side wall and the adjacent end wall, a diagonally creased panel, the diagonal crease extending from the intersection between the base, the side wall and the end wall. The side walls are folded over on to the base and the portion of each diagonally creased panel between the diagonal and the end wall being secured to the end wall, whereby, when the side walls are pulled upwardly and outwardly from the base, the end walls are lifted. Each side wall has along the upper edge thereof a ledge panel extending inwardly of the box and parallel to the base and the end walls each have a flap along the upper edge thereof which is foldable over to extend parallel to the base and to co-operate with the ledge panels to hold the box in shape and provide a continuous ledge surface around the open upper face of the assembled box. Each of the side walls incorporates a secondary side panel with a fixing strip therealong secured to the base whereby to form double side walls.
