Abstract

A pack having an opening region provided in the top of the pack which forms a pouring opening after it is cut through by an applied pouring element, the pouring element including a base body, a cutting element arranged movably therein, and a screw cap, the screw cap being used for first opening of the pack by actuating the cutting element and for reclosure, and the opening region having a weakened line. The weakened line has a round first section and a second section. The first time the composite pack is opened by moving the cutting element, the weakened line is cut in the first section and tears in the second section.

First claim

The invention claimed is:

1. A composite pack, comprising an opening region provided in a top of the pack which forms a pouring opening after the top of the pack is cut through by an applied pouring element, the pouring element comprising a base body, a cutting element arranged movably therein, and a screw cap, the screw cap being used for first opening of the pack by actuating the cutting element and for reclosure, and the opening region having a weakened line in a composite and a hinge region, on which a part of the opening region formed after the weakened line is cut through is tilted into an interior of the pack and held there, wherein the hinge region is formed by a straight line, the weakened line has a round first section and a second section, which is directly connected to and extends essentially straight between the first section and the hinge region, the hinge region and the second section extending substantially perpendicular to one another, such that, a first time the composite pack is opened by moving the cutting element, the weakened line is cut in the first section and tears in the second section.

2. The composite pack according to claim 1 , wherein the hinge region is also weakened in at least one layer of a composite material.

3. The composite pack according to claim 1 , wherein the first section of the weakened line adjoins the hinge region in continuation thereof.

4. The composite pack according to claim 1 , wherein the first section of the weakened line approximately describes three-quarters of a circle.

5. The composite pack according to claim 1 , wherein an end of the second section of the weakened line extends as far as a free end of the hinge region.

6. The composite pack according to claim 4 , wherein the first section of the weakened line describes a circle arc of 270°.

7. The composite pack according to claim 5 , wherein an angle between the hinge region and the end of the second section of the weakened line is a right angle or obtuse angle.

8. The composite pack according to claim 1 , wherein the weakened line is produced by a laser.

9. The composite pack according to claim 1 , wherein the weakened line is produced mechanically as stamped or grooved lines.

10. A blank made of cardboard/plastic composite material for producing composite packs according to claim 1 , wherein the composite is weakened by a perforation in an opening region by means of weakened lines applied or introduced.

11. The pouring element for use with the composite pack according to claim 1 , the pouring element comprising the base body, the cutting element arranged rotatably therein, and the screw cap, for use with the composite pack, wherein the cutting element executes a rotation of about 360° a first time the pouring element is opened, and has the cutting spike which cuts through an opening region of the pack along the weakened line when the screw cap is actuated, and tilts the part of the opening region formed after the weakened line is cut through into the interior of the pack and holds the part of the opening region in the tilted position.
