Abstract
The invention relates to a method for the manufacture of a blank and/or a container 10, 10a, 11a, 11b, the container body 12 of which has a closed base part, comprising a multilayer structure, made up of a first plastic material 15 and a second plastic material 16, from which an injection moulding machine 30 injection moulds the container 11a, 11b, 11c or a preform 10a, 10b, 10c for the container. According to the invention the injection moulding mould is controlled in the moulding of the container or the preform in such a way that the second plastic material 16 is located in the base part 10a, 20b, 20c of the container, the second plastic material 16 having a greater rigidity than the first material 15 at a temperature in excess of the softening point of the first material. The invention further relates to a container, which is manufactured by the abovementioned method, at least central sections 21, 21a of the base part 20, 20a containing one or more discs 22 and/or annular sheets 22a of the second plastic material 16, which has a greater rigidity than the first plastic material 15 at a temperature in excess of the softening point of the first material. <IMAGE>
