Production method of glass vials
【Technical field】
The present invention relates to a method for the production of glass vials, in particular medicinal vials or medicinal ampoules, and glass vials produced therefrom.
【Background technique】
[0002] Glass bottles for medicinal purposes (also called so-called "vials") consist of neutral glass, i.e. glass that can be classified as hydrolysis class 1, for which the standardized test ISO 719 (DIN 12111) is also used. In particular borosilicate glasses such as DURAN® or Fiohx® (both are registered trademarks of SCHOTT AG, Mainz) are neutral glasses.
[0003] Pharmaceutical vials or pharmaceutical ampoules, respectively, must additionally have as low an alkali metal emission as possible, wherein the measurement is carried out according to the standardized test ISO 4802. Furthermore, so-called delamination, ie spalling of regions on the glass surface, caused by glass constituents which evaporate and deposit on the glass surface, in particular during thermoforming, must be avoided. That is, in the most severe cases, such a delamination can enter the contents of the pharmaceutical vial and thus can destroy the contents.


1. In terms of manufacturing process, medicinal glass bottles are generally divided into two categories: molded bottles and tube bottles. Molded bottles are divided into large-mouth bottles (bottle diameter above 30MM) and small-mouth bottles. The former is used to hold powder, block and paste items, and the latter is used to hold liquid.
2. According to the form of the bottle mouth, it is divided into cork bottle mouth, screw bottle mouth, crown cap bottle mouth, rolling bottle mouth and frosted bottle mouth, etc. According to the usage, it is divided into "single-use bottles" which are discarded after one use and "recycling bottles" which are used for multiple turnovers.
3. According to the contents, it can be divided into acid bottles, medicine bottles, reagent bottles, infusion bottles, preparation bottles, etc.

4. Medicinal glass bottles can be roughly divided into the following categories according to the different uses of medicines: packaging of infusion solutions, packaging of oral liquids, packaging of tablets and capsules, and packaging of powder injections. Infusion solution packaging: domestic large infusion packaging is mainly glass infusion bottles

1, rotation speed: in a centrifuge tube expansion process, the rotational speed and diameter determined centrifugal force. When the diameter is constant, the higher the speed, the greater the centrifugal force. Under centrifugal force, the larger the diameter, the slower the speed. Thus, during the pipe expansion rate should be used as the basis to the diameter of the glass tube

2, the wall thickness is determined, and the corresponding temperature. Heating and softening the pressure in the pipe expansion process, the control diameter sizing device mainly depends on a set of synchronous rotation of the glass tube, it requires a wider range of speeds.




The purpose is to eliminate permanent stress and structural imbalance in glass products. Glass is a poor thermal conductor. After the product is formed, the surface layer and the inner layer will have a temperature difference during the cooling process. When the surface layer is solidified and the inner layer is viscous, the temperature difference exists but the stress relaxation does not exist. This temperature difference occurs when the surface layer is cooled to room temperature. , The inner layer continues to cool down and shrinks, which is hindered by the surface layer to produce tensile stress, and at the same time, the surface layer produces compressive stress, which is permanent. The size and distribution of the permanent stress caused by the thermal process in each part of the product will not be uniform, therefore, it will affect the strength of the glass product, and even break by itself due to stress concentration. Annealing can eliminate harmful tension inside the glass and prevent new stress from being generated.
