    • This invention relates to a syringe barrel (1) which, at least in part, has a cylindrical portion (2), whereby a needle (4) is fixed in an axial end portion (3) of the cylindrical portion (2), whereby the needle (4) is arranged in a receiving channel (5) in the axial end portion (3) of the cylindrical portion (2) and whereby the needle (4) is fixed in the receiving channel (5) in at least one fixing area (6, 7) using material of the cylindrical portion (2) which, after melting, bonds around the circumference of the needle (4), seals it and forms a bond between the cylindrical portion (2) and the needle (4). In order to achieve that the needle is fixed more reliably in the syringe barrel and to minimize the dead space volume for drug in the syringe barrel as, well as to improve sterilization, the invention provides that there are at least two fixing areas (6, 7) arranged at an axial distance (a) which fix the needle (4) in the axial end portion (3) of the cylindrical portion (2). Furthermore the invention relates to a method for producing a syringe barrel.
    • 本发明涉及一种至少部分具有圆柱形部分(2)的注射器筒(1),其中针(4)固定在圆柱形部分(2)的轴向端部(3)中,由此 针(4)布置在圆柱形部分(2)的轴向端部(3)中的接收通道(5)中,并且由此将针(4)固定在接收通道(5)中,至少一个固定 区域(6,7)使用圆筒部分(2)的材料,其在熔化之后围绕针(4)的周围粘合,将其密封并在圆柱形部分(2)和针(4)之间形成结合部分, 。 为了实现针在注射器筒中更可靠地被固定,并且为了使注射器筒中的药物的死空间体积最小化,以及为了改善消毒,本发明提供了至少两个固定区域(6, 7),所述轴向距离(a)将所述针(4)固定在所述圆筒部(2)的轴向端部(3)中。 此外,本发明涉及一种用于生产注射器筒的方法。

    • Methods of plastically forming an axially extended zone of the interior surface of a hollow glass tube heated to its forming temperature employ a generally cylindrical embossing mandrel connected to a driving shaft. The hollow glass tube and the embossing mandrel are brought together at a predetermined start position for the embossing mandrel inside the glass tube and are brought into contact in an area in which the zone is to be formed on the interior surface of the glass tube. A relative rolling off planetary motion between the embossing mandrel and the glass tube is provided while plastically forming the zone of the glass tube and creating depressions therein. The rolling off planetary motion is achieved by (i) rotating the embossing mandrel around the longitudinal axes of the embossing mandrel and the glass tube, (ii) rotating the embossing mandrel around its longitudinal axis and rotating the glass tube around its longitudinal axis, or (iii) rotating the glass tube around the longitudinal axes of the glass tube and the embossing mandrel. The glass tube and embossing mandrel are then separated.
