| abstract |
The present invention relates to a container precursor comprising a wall, wherein the wall a) surrounds an interior region, and b) comprises a first wall region and a second wall region; wherein the first wall region comprises a first layer sequence, the first layer sequence comprises a first A wall layer, a second wall layer and a third wall layer as an overlying layer from the inner region to the outside; wherein in the first wall region the second carrier layer is characterized in that it is more dense than the first carrier layer or the third carrier layer or both smaller layer thicknesses; wherein the second wall region comprises a second layer sequence comprising a first wall layer, a second wall layer and a third wall layer as an overlying layer from the inner region outwards; Wherein, in the second wall region, the second wall layer is connected to the third wall layer; wherein, in the second wall region, the third carrier layer is characterized by being more dense than the first carrier layer or the third carrier layer or both Large layer thickness. Furthermore, the present invention relates to a method for manufacturing a container precursor, a container precursor obtained by the method, a closed container, a method for manufacturing a closed container, a closed container obtained by the method, a use of the above-mentioned container precursor, and the above-mentioned container Another use of the precursor. |
