[0048] Hereinafter, a first embodiment of the present invention will be described with reference to the drawings.

[0049] [point burner 30]

[0050] figure 1 and figure 2 The illustrated point burner 30 is used in the method of producing medical glass containers according to the invention. In the second process of the invention, the spot burner 30 is used to treat the inner surface of the ampoule 70 .

[0051] The point burner 30 is mainly roughly divided into a burner body 31 and a nozzle 32 . The burner body 31 has a first flow channel 33 through which mixed gas flows and a second flow channel 34 through which oxygen flows. Mixed gas is a mixture of gas and oxygen. The first flow passage 33 is formed by a first circular pipe 35 serving as a main part of the combustion body 31 . On the top end (nozzle 32 side) of the first circular pipe 35, the second flow passage 34 extending in the diameter direction is connected to the first flow passage 33, and the second flow passa...

[0082] Hereinafter, a second embodiment of the present invention will be described. In the second embodiment, a vial 50 is used as the glass container of the present invention instead of the aforementioned ampoule 70 . In addition, the spot burner 10 suitable for the second process on the vial 50 is used instead of the spot burner 30 described above.

Abstract

The invention provides a method for easily producing a medical glass container with slightly eluted alkaline constituents, comprising the following steps: processing a glass tube 65 into a glass tube shape with a bottom 73 and an opening 71 to provide a narrowneck bottle 70; spraying the flame 23 of a burner 30 into the inner space 72 of the narrowneck bottle 70 to apply the flame 23 on the inner circle surface 75. Thus the alkaline constituents adhered or kept on the inner circle surface 75 of the narrowneck bottle 70 is blown away. Thus the narrowneck bottle with slightly eluted alkaline constituents is produced at the low cost.

Description

technical field [0001] The present invention relates to a glass container for medical use having little elution of alkaline components etc. from the inner wall surface of the glass and a production method thereof. [0002] The invention also relates to a burner suitable for inner surface treatment of medical glass containers. Background technique [0003] As glass containers for storing medicines and the like, for example, ampules and vials are well known. Ampoules and the like are formed of, for example, glass tubes. The main components of glass include alkaline components. It is known that a basic component such as basic boric acid can be adsorbed or condensed on an ampoule or the like. When these alkaline components are eluted into the medicine contained in the ampoule or the like when the ampoule or the like is used as a medicine storage container for medical use, the medicine may deteriorate. To solve this problem, the inner surface of the vial should be subjected t...
