Blow moulding a container, including extruding a tube shaped, hollow, elongated parison from an extrusion head having one free end; and closing a moulding equipment around the parison. The moulding equipment includes a moulding cavity and at least one aperture providing an opening into the moulding cavity from outside the moulding equipment. An excess section of the parison is arranged inside the at least one aperture. The free end of the parison is kept in place in the moulding equipment opposite the at least one aperture. The method includes holding the excess section of the parison within the at least one aperture via a holding force; cutting the parison outside the equipment, thereby providing an open end; arranging a blow pin to close the open end of the parison; and blowing pressurised gas from the blow pin into the parison, thereby forming a blow moulded container within the moulding cavity.

The invention relates to a method for producing a plastic article and a blow molding tool for performing the method. The method comprises extruding an approximately tube-shaped preform, dividing the melt flow within the extrusion head or separating the extrudate exiting or already exited from the extrusion head, such that a preform having an approximately C-shaped cross section is obtained, forming the preform into a hollow part within a multipart blow molding tool using differential pressure, wherein an expansion and partial preforming of the preform first takes place with the blow molding tool partially closed, then in a further step at least one insert is inserted into the interior of the partially preformed article between the not completely closed blow molding tool and through the open side of the preform, and in a further step the blow molding tool is completely closed, wherein the article is completely formed, forming at least one at least partially circumferential pinch-off seam.
