Claim 9:
10. Method according to claim 7, characterized in that the method comprises the following steps:
(i) inserting the plunger-type stopper into a tubular barrel (30);
(ii) inserting a filled syringe cylinder into a receptacle (18) adapted thereto comprising a first centering receptacle (22) adapted to hold a second centering receptacle (24) and the second centering receptacle (24) adapted to hold the syringe cylinder;
(iii) displacing the second centering receptacle (24) with the syringe cylinder to a predetermined position within the first centering receptacle (22), wherein the predetermined position is advantageously achieved by placing the second centering receptacle (24) against a depth stop (26) mounted in the first centering receptacle (22);
(iv) arranging the barrel (30) with the plunger-type stopper in a holding device (28);
(v) adjusting the receptacle (18) with the syringe cylinder and the barrel (30) so that they are aligned substantially coaxially with each other;
(vi) releasing a securing device (50) adapted to prevent inadvertent displacement of the plunger-type stopper relative to the barrel (30);
(vii) displacing the plunger-type stopper within the barrel (30) by exerting a compressive force on a plunger (44) adapted to displace the plunger-type stopper relative to the barrel (30), wherein the plunger-type stopper, arranged at the end of the plunger-type stopper opposite to the plunger (44), is displaced to a predetermined position by means of the compressive force exerted on the plunger (44), wherein the predetermined position of the plunger-type stopper is achieved by placing a depth stop (46) arranged on the plunger (44) against a plunger guide (42); and
(viii) displacing the barrel (30) relative to the plunger-type stopper by holding the plunger-type stopper in the predetermined position within the syringe cylinder by exerting a holding force on the plunger-type stopper via the plunger (44), which rests against the plunger guide (42) with the depth stop (46); and
exerting a compressive force on a first end (38) of an elongated plate-like element (34), thereby transmitting to the barrel (30), at a second end arranged opposite to the first end (38) and at least partially surrounding the barrel (30), a lever force whose direction is substantially opposite to the compressive force,
wherein the plunger-type stopper completely emerges from the barrel (30) and expands to contact an inner surface of the syringe cylinder.
