Claim:
A moulding method for a blowing and/or vacuum forming of a dispensing container filled with a medium to be dispensed, the method comprising the steps of: extruding a plastic tube into an opened mould having movable primary mould section jaws and movable secondary mould section head jaws; cutting the plastic tube in an area located outside the primary and secondary mould section jaws to form an insertion end opening in the plastic tube; closing the primary mould section jaws ( 8 ) for formation of a mould cavity for a dispensing container body and heat sealing of the plastic tube at an end opposite the end opening for formation of a container bottom; expanding the plastic tube against mould walls of the primary mould section jaws by at least one of blowing of air through the insertion opening and by generating a vacuum on the mould walls to form the container body; charging of the container body in the mould with the medium to be dispensed; introducing a sealing unit through the insertion opening and into a section of the plastic tube extending through the secondary mould section jaws, the sealing unit having a dispensing cannula with a projecting outer end through which the medium is to be dispensed and a cannula protective device mounted adjacent the cannula and movable between an advanced protective position and a retracted service position; and closing of the secondary mould section head jaws and thereby moulding of a section of the plastic tube extending through the secondary mould section jaws to form a protective hood enclosing the cannula of the sealing unit and the protective device.
