Abstract
A moulding method, in particular a blowing or vacuum moulding method produces 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, involves introduction of an extruded plastic tube (6) into an open mould with moving main mould sections (8) and mould sections (10), cutting the plastic tube (6), spreading the plastic tube (6) into contact with the mould walls of the main mould sections (8), filling the container (1) in the mould with the medium for dispensing, introduction of a sealing unit (3), closure of the secondary mould sections (10) and subsequent moulding of the section of plastic tube (6) running through the secondary mould sections (10) to form a protective sleeve (5) which encloses a cannula (11) in the sealing unit (3) as second component of the securing device (5, 17).
