Abstract

The invention relates to the technical field of manufacturing of threaded bottles, and concretely relates to a manufacturing method of a threaded bottle. The method mainly comprises the following steps: 1, making a glass tube blank: annealing a threaded bottle at 500-560 DEG C; 2, cutting the glass tube blank: cutting the glass tube blank to make the length be 2-3 times the length of the finished glass tube; 3, making a glass tube blank respectively fixing two ends of the cut glass tube blank on a device, heating the middle position of the glass tube blank by using flame combustion to 600-1500 DEG C for 30-55 s, and slowly stretching the glass tube blank in the heating process until the two ends are broken and separated; and placing the separated glass tube base on a molding die, carrying out heating molding, slowly cooling the molded glass tube blank to room temperature, and taking out the cooled molded glass tube blank to obtain the finished threaded bottle. The temperature in the annealing and processing process is accurately controlled to eliminate internal stress in the processing process and avoid the problem of easy damage of the threaded bottle.

Description

technical field

[0001] The invention relates to the technical field of threaded bottle manufacturing, in particular to a method for manufacturing a threaded bottle. Background technique

[0002] Conventionally, a method of manufacturing a screw bottle by processing a tubular glass tube or the like is known. The threaded bottle manufactured by such a method is mainly used in various occasions as a container for storing liquid. Especially in the medical and chemical fields, screw bottles used for the purpose of preserving pharmaceuticals require high forming accuracy. Examples of such threaded bottles include ink cartridges and syringes used as ampoules, vials, and containers for syringes, for example.

[0003] Chinese invention patent CN103052601A discloses a method for manufacturing threaded bottles. When manufacturing a variety of bottles with the same body shape and different mouth diameters, bottles with smaller diameters can be manufactured conveniently and cheaply wit...
