The invention relates to a plastic-parison (preform) 1 of an expandable mass storage container, in particular a storage container having a capacity of at least 5 liters, preferably at least 10 liters, in which case the plastic-pack The listen has a closed-zone and an inflatable hollow body-zone. In order to reduce the cycle time the preform, at least the inflatable hollow-zone of the preform, consists of a plurality of layers 1a, 1b, 1c, in which case each layer is at least 2 mm, preferably Preferably a thickness of at least 3 mm, in which case each of the layers 1a, 1b, 1c in fact has the same layer thickness. In this way, the various layers are produced simultaneously by means of a multi-component injection molding technique using a rotary table technique or an indexing plate technique, resulting in a thick preliminary wall after each shot. Molded article 1 is provided. The invention also relates to a method for producing such a plastic-parison 1 and to an injection molding machine.
