Abstract

The invention relates to a device and method used for pressing at least one area of a packaging. The packaging is composed of a multilayer composite material at least in some areas. A pressing tool used for pressing comprises at least one contour element that can be inserted into an interior of the packaging and at least one pressing element that is arranged outside of the interior and opposite the contour element. The pressing element and the contour element are arranged so that the pressing element and the contour element can be positioned relative to each other. The pressing element has an elastic consistency and is provided with a flexible reinforcing device at least in the area of the extent of the pressing element facing the contour element.

First claim

The invention claimed is:

1. A device for pressing at least one area of a packaging composed at least over areas thereof of a multilayer composite material, comprising a base having a recess with a base surface and forming an opening: a pressing tool having at least one contour element insertable into an interior space of the packaging; at least one pressing element arranged externally relative to the interior space and located opposite the contour element, the pressing element and the contour element being positionable relative to each other, the pressing element having an elastic consistency; and a flexible reinforcing device arranged to extend across the opening and at least in an area of an extension of the pressing element facing the contour element, wherein the pressing element is arranged in the recess of the base so as to be between the base surface and the reinforcing device, wherein the reinforcing device includes a plurality of reinforcing elements.

2. The device according to claim 1 , wherein the reinforcing device includes a plurality of ring-like reinforcing elements.

3. The device according to claim 2 , wherein the ring-like reinforcing elements engage at least partially into each other.

4. The device according to claim 2 , wherein the reinforcing elements have a substantially circular ring-shaped configuration.

5. The device according to claim 1 , wherein the reinforcing device is at least partially made of metal.

6. The device according to claim 1 , wherein the reinforcing device is arranged in an area of a surface of the pressing element.

7. The device according to claim 1 , wherein the reinforcing device has portions embedded in the pressing element.

8. The device according to claim 1 , wherein the reinforcing device has portions arranged at a distance from the pressing element.

9. The device according to claim 1 , wherein the pressing tool is constructed to seal overlapping lugs of the packaging.

10. The device according to claim 1 , wherein the pressing tool is constructed to act on at least one portion of a bottom of the packaging.

11. The device according to claim 2 , wherein the ring-like reinforcing elements are interlocking.

12. A method for pressing at least an area of a packaging composed at least over areas thereof of a multilayer composite material, comprising the steps of: introducing at least one contour element of a pressing tool into an interior space of the packaging; providing a pressing element having an elastic consistency; providing a base element having a recess with a base surface and forming an opening; arranging the pressing element in the recess of the base so as to be outside the packaging relative to the interior space and opposite the contour element; providing a flexible reinforcing element, made up of a plurality of reinforcing elements, to extend across the opening of the recess and at least in an area of an extension of the pressing element facing the contour element so that the pressing element is between the base surface and the referencing device; positioning the pressing element and the contour element relative to each other; and pressing the packaging between the pressing element and the contour element.
