Problems solved by technology

As for the material of glass containers, borosilicate glass, soda lime glass, etc. are usually used from the viewpoint of cost and workability, but there are problems as follows: the contents are easy to adhere to the inner surface of the glass container (surface water resistance, Low powder resistance), precipitation of modifying ions (sodium ions, etc.) contained in the glass; when containing a pharmaceutical solution with a high pH, ​​the inner surface of the glass container is eroded, resulting in glass flakes, etc.

Embodiment 1

[0137] (1) Pretreatment with silane coupling agent

[0138] A silane coupling agent (KBE-903, 3-aminopropyltriethoxysilane) was diluted with purified water to prepare a solution having a silane coupling agent concentration of 0.5% by weight. Apply this solution to the inner surface of a vial (20 mL internal capacity, made of borosilicate glass, the same below), centrifuge to discharge the liquid, and bake at 100°C for 30 minutes to obtain a silane coupling agent-treated vial.

[0139] (2) Fluorine resin coating

[0140] An amorphous fluororesin (Teflon AF) was diluted with a fluoroinert liquid (Flurinert FC-40, manufactured by Sumitomo 3M Co., Ltd.) to prepare a solution having a concentration of 4% of the amorphous fluororesin.

[0141] Apply this solution on the inner surface of the vial treated with the silane coupling agent obtained in (1) above, centrifuge to discharge the liquid, bake at 150°C for 20 minutes, and then bake at 250°C for 30 minutes , to produce vials wi...

Embodiment 2

[0144] An amorphous fluororesin (Cytop M) was diluted with a fluorine-based inert liquid (Flurinert FC-40, manufactured by Sumitomo 3M Co., Ltd.) to prepare a solution having a concentration of 4% of the amorphous fluororesin.

[0145] Apply this solution to the inner surface of the vial treated with the silane coupling agent obtained in (1) of Example 1, centrifuge to discharge the liquid, bake at 150°C for 20 minutes, and then bake at 250°C Treated for 30 minutes, a vial with an inner surface treated was prepared.

Embodiment 3

[0147] (1) Pretreatment with silane coupling agent

[0148] A silane coupling agent (KBM-13, methyltrimethoxysilane) was diluted with purified water, acetic acid was added thereto to adjust the pH to 4, and a solution with a silane coupling agent concentration of 2.0% by weight was prepared. Apply the solution to the inner surface of the vial, centrifuge to discharge the liquid, and bake at 200° C. for 30 minutes to obtain a vial treated with the silane coupling agent.

[0149] (2) Fluorine resin coating

[0150] An amorphous fluororesin (Teflon AF) was diluted with a fluorine-based inert liquid (Flurinert FC-40, manufactured by Sumitomo 3M Co., Ltd.) to prepare a solution having a concentration of 1% of the amorphous fluororesin.

[0151] Apply this solution on the inner surface of the vial treated with the silane coupling agent obtained in (1) above, centrifuge to discharge the liquid, bake at 150°C for 20 minutes, and then bake at 250°C for 30 minutes , to produce vials w...

Abstract

The present invention provides a glass container (in particular, a medical glass container) having excellent water repellency, dust repellency, heat resistance, alkali resistance, etc., and a method for manufacturing same. The present invention relates to a method for manufacturing a glass container (in particular, a medical glass container), the method for manufacturing characterized in comprising (1) a step for treating the inner surface of the glass container using a silane coupling agent and / or a partial hydrolysate thereof, and (2) a step for treating the treated surface obtained in step (1) using an amorphous fluorine-based resin; and relates to a glass container obtained using the method for manufacturing same.

Description

technical field [0001] The present invention relates to a glass container, especially a glass container for medical use, and more specifically, a glass container for containing chemicals such as pharmaceuticals and detection reagents. Background technique [0002] Glass containers excellent in barrier properties to water vapor, oxygen, and the like are widely used as medical containers for containing chemicals such as pharmaceuticals and detection reagents. As for the material of glass containers, borosilicate glass, soda lime glass, etc. are usually used from the viewpoint of cost and workability, but there are problems as follows: the contents are easy to adhere to the inner surface of the glass container (surface water resistance, Low powder resistance), precipitation of modifying ions (sodium ions, etc.) contained in the glass; when containing a pharmaceutical solution with a high pH, ​​the inner surface of the glass container is eroded, and glass flakes (flakes) etc. ar...
