Embodiment 1

[0332] Example 1 according to the invention was carried out in the same manner as comparative example 2, but differed in that the anvil was placed in the laminate during ultrasonic sealing due to the longitudinal seam arrangement with prepared edges On the thickened side, there is a depression for thickening. The depression has a constant depth over its entire extent, which can receive thickening. Figure 17 A cross-sectional view of the arrangement is shown.

Embodiment 2

[0334] Example 2 according to the invention was carried out in the same manner as Example 1, but the edges of the laminate were prepared differently. During the scraping, the thickness of the carrier layer was initially only reduced by 50% of its original thickness, which was 430 μm. Furthermore, folds are produced in the scraped edge region, so that the scraped edge region can lie along the fold so that it lies entirely on itself. Thus, the scraped areas are not placed on top of the unscraped areas. In this way, with less scraping, a somewhat smaller thickening of the longitudinal seam is achieved. The constant depth of the depression in the anvil is adapted thereto. Figure 18 A cross-sectional view of the arrangement is shown.

Embodiment 3

[0336] Example 3 according to the invention was carried out in the same manner as Example 2, the preparation edge was deviated again. Scraping was performed as described in Example 2. However, the scraping area is folded so that it does not completely surround itself, but on itself and partly on the non-scraping area. The constant depth of the depression in the anvil in turn accommodates the varying thickening of the longitudinal seam. Furthermore, the depressions are again arranged on the sides of the thickening. Figure 19 A cross-sectional view of the arrangement is shown.

Abstract

The present invention relates to a device and a method for closing a container front body. The device comprises a first fixing element, a further fixing element and a folded planar composite; whereinthe first fixing element comprises a first fixing surface and the further fixing element comprises a further fixing surface; wherein the folded planar composite is at least partially fixed between thefirst fixing surface and the further fixing surface; wherein the folded planar composite comprises a first composite region; wherein the first composite region comprises a first layer sequence comprising a first composite layer comprising a first carrier layer, a second composite layer comprising a second carrier layer, a third composite layer comprising a third carrier layer and a fourth composite layer comprising a fourth carrier layer; wherein in the first composite region the second composite layer is joined to the third composite layer and the third composite layer is joined to the fourth composite layer; wherein in the first composite region the third carrier layer is characterised by a smaller layer thickness than in each case one selected from the group consisting of the first carrier layer, the second carrier layer and the fourth carrier layer or a combination of at least two of these; wherein the first fixing surface or the further fixing surface or both comprises a recess comprising a first recess region; wherein the first composite region is located at least partially between the first recess region and the first fixing surface or the further fixing surface.

Description

technical field [0001] The invention relates to a device comprising a first fixing element, a further fixing element and a folded planar composite material, in particular for closing a container precursor comprising a planar composite material; Method for joining a composite layer to a second composite layer of planar composite material; closed container obtainable by the above method; closed container, including seams and recesses; and use of the above device. Background technique [0002] For long shelf life foods, whether they are food for human consumption or animal feed products, storage is usually done in cans or glass jars with lids. Here, on the one hand, the shelf life can be increased by sterilizing the food and the container (here glass jars or cans) as much as possible, and then filling the container with the food and closing it. However, these long-proven measures for increasing the shelf-life of foodstuffs have a number of disadvantages, such as the again requ...
