ABSTRACT:
The invention relates to a moulding method, in particular a blowing or vacuum moulding method for production of a dispensing container filled with a medium for dispensing. A moulding method for production of a dispensing container (1), filled with a medium for dispensing, comprises the following steps: introduction of an extruded plastic tube (6) into an open mould with moving main mould section (8) and mould section (10), cutting the plastic tube (6), spreading the plastic tube (6) into contact with the mould walls of the main mould section (8), filling the container (1) in the mould with the medium for dispensing, introduction of a sealing unit (3), closure of the mould section (10) and subsequent moulding of the section of plastic tube (6) running through the mould section (10) to give a protective sleeve (5) which encloses a cannula (11) in the sealing unit (3) as second component of the securing device (5, 17).
