  • Patent number: 8617676
    Abstract: A preform is disclosed for producing plastic flasks in a two-stage stretch blow-molding process, including a preform base, an elongated preform body, including one longitudinal end sealed to the preform base and another longitudinal end sealed to the neck portion a neck portion with threaded sections or positive protrusions, wherein the preform is manufactured from a plastic that is suitable for the stretch blow-molding process, which has a refractive index of 1.3 to 1.6 at a temperature of 10° C. to 120° C., and in that an outside wall and an inside wall of the preform base bound a flat divergent lens, and in each case have radii of curvature (c, b) that are larger by at least a factor 1.4 than a related radius of curvature (s) of an outside wall or a radius of curvature (R) of an inside wall of the preform in the area of the preform body.

  • Publication number: 20080128959
    Abstract: Process for producing plastic containers, including an extrusion blow molding machine, is disclosed. For example, in an extrusion blow molding process for plastic bottles, in which plastic tubing (T) which has been extruded from an extruder head (4) in a definable cycle is placed in the mold cavity (7) of a blow molding tool arrangement (6), the inserted plastic tubing is inflated via an infeed blow mandrel by overpressure according to the mold cavity and is then removed from the mold. The extruded plastic tubing (T) is inserted into a mold cavity (7) which is composed of several blow mold cavities (71, 72, 73) which are located axially under one another, two of the blow mold cavities (71, 72) at a time being arranged mirror-symmetrically to one another and connected on their mouth regions and an individual blow mold cavity (73) being separated from the bottom section of the adjacent blow mold cavity (72) by a land region and having a mouth (10) on the outer surface of the blow molding tool arrangement (6).
