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.
