Abstract: A method for producing glass vials, in particular pharmaceutical vials or pharmaceutical ampoules, from a glass tube is provided, the method including the following steps: (a) rotating the glass tube about a longitudinal axis thereof; (b) locally heating the glass tube from one side by means of at least one burner to at least the softening temperature of the glass; (c) reducing the diameter by pressing at least one forming body laterally against the heated region; and (d) separating the glass tube by means of a burner. A glass vial produced in such a way releases a reduced amount of alkali in accordance with ISO 4802 and has a decreased delamination tendency. Furthermore, in the hot-formed peripheral region, the alkali content is only slightly reduced when compared with the alkali content in the glass interior.

Abstract translation: 提供了一种从玻璃管制造玻璃小瓶，特别是药瓶或药用安瓿的方法，该方法包括以下步骤：（a）围绕其纵轴旋转玻璃管; （b）通过至少一个燃烧器将玻璃管从一侧局部加热至至少玻璃的软化温度; （c）通过将至少一个成形体横向压靠在加热区域上来减小直径; 和（d）借助燃烧器分离玻璃管。 以这种方式生产的玻璃小瓶根据ISO 4802释放减少量的碱，并且具有降低的分层趋势。 此外，在热成形周边区域中，与玻璃内部的碱含量相比，碱含量仅略微降低。
