The present invention relates to a sheet-like composite comprising as layers of a layer sequence in a direction from an outer side of the sheet-like composite to an inner side of the sheet-like composite a) a carrier layer, and b) a barrier layer comprising i) a barrier substrate layer, and ii) a barrier material layer; wherein the barrier material layer has a thickness in a range from 1 nm to 1 μm; wherein the barrier material layer overlies the barrier substrate layer on a layer surface of the barrier substrate layer that faces the inner side. The invention further relates to methods for producing a sheet-like composite, a container precursor and a closed container, and also to the aforesaid method products; to a further container precursor; to a further closed container; and to a use of the sheet-like composite.

A device is shown and described for ultrasonic welding of composite material, in particular composite material of package sleeves and/or packages, including at least two tools for ultrasonic welding, in particular a sonotrode and an anvil. Each tool has a functional surface for contact with the material to be welded. The functional surfaces of the tools are aligned approximately parallel to one another in such a way that a gap with an approximately horizontal seam direction is created between the functional surfaces. The tools are mounted in such a way that the width of the gap can be changed by at least one of the tools being movable along a feed direction, and at least one joint having at least one axis of rotation about which one of the tools is rotatable. In order to enable optimal adaptation of the movably mounted tool—for example the sonotrode—to the materials to be welded and their size, it is proposed that the position of the axis of rotation can be changed.

The present invention relates to a sheetlike composite comprising, as mutually superposed layers, a) a carrier layer, b) a barrier layer, and c) an inner polymer layer, wherein the sheetlike composite has a multitude of groove lines arranged and configured such that, by folding the sheetlike composite along the groove lines and joining seam areas of the sheetlike composite thereby obtaining seams, a closed container is obtainable, wherein the closed container has a roof area, wherein a first portion of the groove lines of the multitude of groove lines at least partly forms a circumference of a first part-area of the roof area, wherein the groove lines of the first portion, relative to the first part-area of the roof area, have at least partly convex curvature, wherein the first part-area of the roof area has a first length in a longitudinal direction and has a second length in a circumferential direction at right angles to the longitudinal direction, wherein a ratio of the first length to the second length is in a range from 0.2 to 2.0. The invention further relates to methods of producing a sheetlike composite, a container precursor and a closed container, and to the aforementioned method products; to a further container precursor; to a further closed container; and to a use of the sheetlike composite.

A spout ( 1, 401, 601 ) having a plastic spout body which comprises an attachment portion ( 10, 410, 610 ) having a vertical first plane of symmetry (M 1 ) with a vertical first sealing wall ( 11, 411, 611 ) and an opposed vertical second sealing wall ( 12, 412, 612 ), and with a transverse wall ( 20 ), which is integrally connected to an upper edge of the first sealing wall and to an upper edge of the second sealing wall, wherein the first sealing wall and the second sealing wall each depend from said transverse wall and each have a bottom edge ( 114, 115, 541, 515, 714, 715 ) remote from the upper edge. Each sealing wall is, seen in a bottom view of the attachment portion, composed of a first rectilinear portion ( 111, 121, 511, 521, 711, 721 ), a central curved portion ( 113, 123, 513, 523, 713, 723 ), and a second rectilinear portion ( 112, 122, 512, 522, 712, 722 ). The spout body has a tubular neck ( 30 ) having a bore ( 31 ) that adjoins an opening ( 21 ) in the transverse wall. The attachment portion further comprises curved stabilizing ribs ( 15, 16, 151, 161, 152, 162 ) extending between associated connection points to the opposed rectilinear portions of the sealing walls.

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, 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. The manufacture of packages with even more complex geometries without impairing the rigidity of the package should be achieved by a third sleeve fold line, which has a plurality of sections, which each adjoin a side surface and a rear surface, and of which at least one section is curved and of which at least one section is straight. 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.

A sealing station configured to heat seal a wall made from heat-sealable film material, preferably metal-free heat-sealable film material, onto one another wall of heat-sealable material, e.g. another wall of heat-sealable film material, to create a sealed seam. The sealing station comprises an impulse sealing device comprising a first jaw and a second jaw, wherein at least the first jaw comprises at the respective front surface thereof at least one, e.g. a single elongated, impulse heatable member that extends along the respective front surface and that is covered by a heat-resistant non-stick covering.

A package made of a composite material is represented and described, including: a package base with two front base corners and with two rear base corners, a package gable with two front gable corners and with two rear gable corners, and a package base body with a front panel, a first side panel, a second side panel and a rear panel. The package base and the package gable are arranged on opposite sides of the package base body. The composite material has a polymer inner layer, a polymer outer layer and a fibrous support layer, which is arranged between the polymer outer layer and the polymer inner layer. 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 package base body has at least one stress-relief panel, which is arranged between the front panel and one of the two side panels.
