Abstract: The invention relates to a method for producing a container (2) from a thermoplastic, having at least one surround (4), provided in the container wall (1), for a container opening. The surround (4) comprises a structure behind which parts of the container wall (1) extend and/or which is penetrated by said parts. The method is carried out using a multi-part blow mold that has at least two mold parts, each having at least one cavity, wherein the surround is placed as an insert in the cavity (10) of the blow mold (7). The method comprises pressing the preform that has been forced into the cavity (10) into the structure of the surround (4) by means of a tool which is brought to bear on the preform (12) on the side of the preform facing away from the cavity (10).

Abstract: The invention relates to a method for producing hollow bodies from thermoplastic material by using an at least three-part blow-molding tool with at least two blow-mold halves (1a, 1b), which define a mold impression, have part-cavities (5a, 5b) and can be displaced toward one another and away from one another in the sense of an opening and closing movement, and also with at least one central tool (2), which is displaceable transversely in relation to the opening and closing movement of the blow-mold halves (1a, 1b), the method comprising the extruding or providing and arranging of at least two molten performs (7) of thermoplastic material in web form between the blow-mold halves (1a, 1b) in an opened receiving position, the bringing to bear of the preforms (7) in the part-cavities (5a, 5b) of the blow-mold halves (1a, 1b) and molding of them into shells (10) using sealing elements which are provided on the central tool and are extended from the central tool for the purpose of sealing off the part-cavities bef
