A flat-shaped composite material is represented and described for manufacturing a package, including: a polymer outer layer, a polymer inner layer, a fibrous support layer, which is arranged between the polymer outer layer and the polymer inner layer. The flat-shaped composite material has a plurality of fold lines, which are arranged and designed such that a closed package can be manufactured by folding the flat-shaped composite material along the fold lines and by connecting seam surfaces of the flat-shaped composite material and a sleeve surface. The sleeve surface includes a front surface, a first side surface, a second side surface, a first rear surface and a second rear surface, and base surfaces. The base surfaces include triangular base surfaces, quadrangular base surfaces, and gable surfaces. The gable surfaces include triangular gable surfaces and quadrangular gable surfaces. The base surfaces and the gable surfaces are arranged on opposite sides of the sleeve surface. In order to enable the manufacture of packages with even more complex geometries without impairing the rigidity of the package, it is proposed that the sleeve surface has at least one stress-relief surface, which is arranged between the front surface and one of the two side surfaces. A package sleeve made of a composite material and a package manufactured from the composite material or from the package sleeve are also represented and described.

The present invention relates to a single-use container (200) manufactured from sheet material, the single-use container comprising: a base (206), wherein the base is flat and forms a surface on which the single-use container can stand,a front wall (201), a right wall (202), a left wall (203) and a rear wall (204) which extend upward from the base, wherein the front wall and the rear wall are convex, and wherein the right wall and left wall are concave, an upper end (207) which connects the front wall, right wall, left wall and rear wall.

A paper inner container for storage of refilling liquid content, which enables a suction port to be easily formed at a center of an upper surface thereof. The paper inner container includes: four body panels, which form a body having a square tubular shape; and a pair of upper-surface forming panels and a pair of side panels, which are continuously provided on upper edges of the body panels to form an upper surface. The pair of upper-surface forming panels face each other and overlap in a vertical direction. The pair of side panels are positioned between the pair of upper-surface forming panels to face each other and are folded up along with overlapping of the upper-surface forming panels. The pair of upper-surface forming panels have holes, which are formed at centers of the upper-surface forming panels to serve as a suction port.

A carton blank for forming a carton, and comprising a row of first, second, third and fourth substantially four-edged panels, each panel having substantially the same width and comprising a side wall part, a top closure obturating part and a top sealing fin part, one of said panels from an outermost boundary of the side wall part to an outermost boundary of the top closure obturating part being substantially free from any lateral line of weakness, the obturating part of said one of said panels including a loop of weakness.

Provided is a package sleeve made of a composite material for the manufacture of a package. The package sleeve includes a sleeve surface with an inner partial area and two outer partial areas, a longitudinal seam connecting two edges of the composite material to form a circumferential package sleeve, and two secondary fold lines running through the sleeve surface. The package sleeve is folded along two secondary fold lines. Apart from the two secondary fold lines, the package sleeve does not contain any further continuous fold lines in the region of the inner partial area of the sleeve surface. Also provided are a package and a method for manufacturing a package.

Provided is a sleeve blank which includes a first polymer layer; a support layer on the polymer layer; a barrier layer on the support layer; and adhesive layer on the barrier layer; and a second polymer layer following on the adhesive layer facing a second outer side. At least a part of the layers are deformed through at least one first and one second crease line, each possessing starting an end points. Each crease line runs along an imaginery line which corresponds to the respective crease line, and projects beyond its beginning and/or end through imaginary continuation thereof. The crease lines separate regions forming sleeve, gable and base surfaces. The sleeve blank includes at least one point of intersection of imaginery lines and is free of any point of intersection of the crease lines, at least in the forming sleeve surfaces, gable surfaces, and/or base surfaces.

The invention relates to packaging (10) for the cooled storage of at least one product (12), with (a) an outer casing (14) that comprises (i) a base (22) and (ii) at least three walls (24), (b) an inner compartment (16) for accommodating the product (12) and (c) a coolant compartment (18) that (i) surrounds the inner compartment (16) on at least three sides and (ii) is water-tight, wherein (d) the outer casing (14) surrounds the coolant compartment (18) and wherein (e) the outer casing (14) and the inner compartment (16) are designed in such a way that the coolant compartment (18) is water-tight and can be filled with water such that, after the water freezes, the water cools the products (12) in the inner compartment (16).
