Abstract
Disclosed is a method and a system for producing an ampoule filled with a medical liquid. A preform is produced by plastic injection moulding that is then inhomogeneously heated and blown to form an ampoule body. Further disclosed is an ampoule produced by means of stretching and blowing, which comprises a connector with a break-off part in which the predetermined breaking point is aligned with the septum of the connector.
Claims15
A method for producing an ampoule filled with a medical liquid, wherein a preform is produced by a plastic injection molding process, which is reshaped to form an ampoule by heating and blowing, which comprises a longitudinal side and a narrow side in the cross-section, wherein the preform is heated prior to reshaping by blowing in such manner that it is heated more strongly in a region of the side wall, which is reshaped to form a region of the side wall of the longitudinal side of the ampoule, than in an adjoining side wall region of the narrow side, wherein the ampoule is filled with a medical liquid after reshaping and is sealed and in that the ampoule is sealed with a connector, which comprises a septum and a break-off part and wherein a predetermined breaking point for the break-off part aligns substantially with an upper side of the septum and in that the septum is wipeable.
A method comprising using a system for producing an ampoule that is filled with a medical liquid, wherein the system comprises a station for injection molding a preform, an apparatus for heating the preform, and a station for blowing the preform to form the ampoule, wherein the apparatus for heating the preform is formed in such manner that a side wall of the preform is heated to varying extents along a circumference thereof, wherein the ampoule is filled with a medical liquid after reshaping and is sealed and in that the ampoule is sealed with a connector, which comprises a septum and a break-off part and wherein a predetermined breaking point for the break-off part aligns substantially with an upper side of the septum and in that the septum is wipeable.
