  • Method for producing a plastic bottle, and preform and blowing mold suited therefor
    Patent number: 10011064
    Abstract: Method for producing a plastic bottle, and preform and blowing mold suited therefore are disclosed. An exemplary process can produce a plastic bottle, for example, a PET bottle. Such a bottle can be produced from a preform which has a body which is closed on one side, which is connected to a neck section with a pour opening, in which the preform which has been produced in a plastic injection process or an extrusion process is placed in the mold cavity of a blow mold and inflated using the blow nozzle by overpressure according to the mold cavity. Sealing can take place between the blow nozzle and the preform within the preform.

  • Method of attaching a sheetlike object, e.g., a label, to a hollow body of plastics
    Patent number: 4605462
    Abstract: To provide hollow plastic bodies, e.g. bottles, with an inscription, a sheetlike object (23), e.g. a label, is pressed at least in part against an unfinished piece (26) while still being in deformable condition. This unfinished piece (26) is then brought, together with the preliminarily attached label into a blow mould (15). In blowing the bottle (26') the label (23) is strongly pressed against the bottle wall, because the label is held by the inner wall (31) of the blow mould.
