A container for foodstuffs and a method for manufacturing said container

A method for manufacturing a container for foodstuffs, comprising the steps of:

• preparing a flat blank having a first face and a second face opposite to each other and comprising:
• a polygonal base panel perimetrically bounded by a plurality of internal folding lines, and
• a plurality of side panels, equal in number to said plurality of internal folding lines, connected to said base panel in the area of said internal folding lines,
• wherein each side panel is provided with a central portion connected to said base panel, a pair of side tabs arranged on opposite sides of said central portion and connected to said central portion by side folding lines, and an external tab arranged outside said central portion and connected thereto by a first external folding line;
• preforming said blank by at least partially folding, in the area of said first face, said side panels with respect to said base panel along said internal folding lines;
• forming said blank so as to obtain a container for foodstuffs comprising a containment body in which a polygonal bottom wall corresponds to said base panel and the perimeter side walls correspond to said central portions of the side panels, so as to define a containment volume, said forming step comprising the following sub-steps:
• folding said side tabs along said side folding lines until, in the area of said first face, each side tab of a side panel abuts against a corresponding side tab of an adjacent side panel,
• bonding said side tabs abutting against each other, thus defining supporting elements of said containment body outside said containment volume,
• folding each external tab along the respective first external folding line so as to define an edge portion of the container, which is suitable to receive a closure element,
• further folding each external tab along a respective second external folding line so as to define a folded portion of said external tab,
• arranging each external tab so that it partially overlaps and is bonded to at least one adjacent external tab so as to define a continuous folded edge of the container.

A container for foodstuffs, comprising a box-like body manufactured with a multilayer material having an outer layer made of a recyclable and/or biocompostable material and a heat-sealable inner layer, which is gas-tight and made of a material suitable to come into contact with food,

• wherein said box-like body has a polygonal bottom wall and perimeter side walls connected to each other along respective connection lines and to said polygonal bottom wall so as to define a food containment volume facing said inner layer and open at the top at an upper opening,
• wherein at least two side flaps and one upper flap extend from each perimeter side wall,
• wherein each side flap is connected to the respective side wall through a respective side folding line, defining a connection line connecting the respective perimeter side wall, and abuts against and is bonded to a respective adjacent side flap, defining a supporting element outside said containment volume,
• wherein 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,
• said container further comprising a plurality of overlapping sealing elements bonded to said inner layer in the area of said connection lines and at least partially overlapping the respective edge portion of the container.

• a polygonal base panel perimetrically bounded by a plurality of internal folding lines, and
• a plurality of side panels, equal in number to said plurality of internal folding lines, connected to said base panel in the area of said internal folding lines,
• wherein each side panel is provided with a central portion connected to said base panel, a pair of side tabs arranged on opposite sides of said central portion and connected to said central portion by side folding lines, and an external tab arranged outside said central portion and connected thereto by a first external folding line;
• preforming said blank by at least partially folding said side panels with respect to said base panel along said internal folding lines;
• forming said blank so as to obtain a container for foodstuffs comprising a box-like body in which a polygonal bottom wall corresponds to said base panel and the perimeter side walls correspond to said central portions of the side panels, so as to define a containment volume, said forming step comprising:
• folding each external tab along the respective first external folding line so as to define an edge portion of the container, which is suitable to receive a closure element,
• applying a plurality of sealing elements, overlapping them in the area of said connection lines and arranging them at least partially over the respective edge portions of the container,
• bonding said sealing elements to said box-like body.

A container for foodstuffs, comprising a box-like body manufactured with a multilayer material having an outer layer made of a recyclable and/or biocompostable material and a heat-sealable inner layer, which is made of a material suitable to come into contact with food,

• wherein said box-like body has a bottom wall and perimeter side walls connected to each other and to said bottom wall so as to define a food containment volume facing said inner layer and open at the top at an upper opening,
• wherein said bottom wall has at least one window bounded by at least two side edges at least partially facing one another,
• and wherein said bottom wall has at least one partition wall rising transversely from at least one of said side edges of the window and towards the inside of the containment volume up to a free end thereof,
• said container comprising a cover element heat-sealed to the inner layer of the bottom wall and arranged astride said at least two edges so as to occlude the window, wherein the cover element is arranged over said free end of the partition wall and defines a bulge in the bottom wall.

• said blank comprising a base panel perimetrically bounded by at least one internal folding line, and at least one side panel connected to said base panel in the area of said internal folding line,
• wherein said base panel has a window bounded by a closed perimeter line having at least a first and a second edge at least partially facing one another;
• said window being at least partially occluded by a partition wall pivotally attached to the panel at said first edge;
• placing a sheet of heat-sealable plastic material over said window in the area of said first face so that said sheet of plastic material is arranged over said closed perimeter line and said window is completely covered by said sheet,
• sealing said sheet of heat-sealable plastic material to said inner layer along a closed sealing line outside said closed perimeter line bounding the window,
• pushing said partition wall against said sheet of heat-sealable plastic material by folding it along said first edge until it is arranged transversely to said first face, said sheet of heat-sealable plastic material being configured to deform following the movement of the partition wall, so as to cover it, keeping said window covered and defining a bulge in a bottom wall of said container.
