Abstract
The invention relates to a method for producing a syringe having a piercing means, comprising the following steps: a) providing a syringe body having a distal end section, which comprises an inner channel that discharges at a distal opening, wherein the distal end section is in a formable state; b) providing a piercing means; c) inserting a proximal section of the piercing means through the distal opening into the inner channel of the distal end section; and d) shaping the distal end section by means of a first shaping tool in such a way that an inner surface of the distal end section contacts at least portions of the piercing means, as a result of which at least portions of the piercing means are secured.

A method for producing a syringe having a piercing means, comprising the following steps:
- a) providing a syringe body having a distal end section, which comprises an inner channel that discharges at a distal opening, wherein the distal end section is in a formable state;
- b) providing a piercing means;
- c) while the distal end section is in the formable state, inserting a proximal section of the piercing means through the distal opening into the inner channel of the distal end section;
- and
- d) shaping the distal end section by means of a first shaping tool in such a way that an inner surface of the distal end section contacts at least portions of the piercing means, as a result of which at least portions of the piercing means are secured,
- wherein in steps b) and c), the piercing means is rotatably mounted in a holding device.

- b) providing a piercing means;
- c) while the distal end section is in the formable state, inserting a proximal section of the piercing means through the distal opening into the inner channel of the distal end section;
- d) shaping the distal end section by means of a first shaping tool in such a way that an inner surface of the distal end section contacts at least portions of the piercing means, as a result of which at least portions of the piercing means are secured,
- wherein the distal end section has a length (L), wherein the shaping in step d) takes place along a sub-section of the length (L), as a result of which a contact section of the inner channel or the inner surface of the distal end section contacts the piercing means as a result of which, the piercing means is secured, thereby achieving complete contact around the circumference (U) of the piercing means with the inner surface of the distal end section,
- wherein following the shaping in step d), an adhesive is introduced through the distal opening into a distal section of the inner channel, thereby securing the piercing means in the distal end section such that a pullout force of at least 30N is achieved without use of an additional adhesive, wherein the distal section of the channel is limited by the distal opening and the contact section of the channel.

- wherein producing the syringe body comprises the following steps:
- aa) providing a hollow, cylindrical glass preform, which extends along an axial direction (X) and has at least one open distal end, wherein the glass preform features a shaped section that extends from the at least one open distal end in a radial direction (X) and is in a formable state;
- bb) shaping the shaped section to a cone-shaped distal end section of the syringe body by means of a second and a third shaping tool,
- wherein an initial shaping of the distal end section in step bb) and a further shaping of the distal end section in step d) takes place by means of the first shaping tool.
