Novel pharmaceutical glass molding bottle

Abstract

The invention relates to a novel pharmaceutical glass molding bottle and belongs to the technical field of pharmaceutical packaging materials. The novel pharmaceutical glass molding bottle is characterized in that: based on oxide, the bottle comprises the following components in percentage by weight: 69 to 71 percent of SiO2, 0.5 to 1.2 percent of Al2O3, 7 to 9 percent of CaO, 1 to 1.8 percent of MgO, 12 to 15 percent of K2O+Na2O, 0.1 to 0.2 percent of Fe2O3 and 0.1 to 0.15 percent of CeO2; and the lightweight molding bottle is made of the following raw materials in part by weight: 300 to 400 parts of quartz sand, 60 to 70 parts of feldspar, 60 to 65 parts of calcite, 40 to 50 parts of dolomite, 90 to 110 parts of soda and 1 to 5 parts of clarifying agent, wherein the clarifying agent is a mixture of cerium oxide and sodium nitrate. The formula belongs to a soda-lime-silica glass system, adopts a rare earth oxide such as the cerium oxide serving as the clarifying agent to replace conventional selenium and cobalt powder, has the functions of absorbing and blocking harmful ultraviolet rays in 220 to 400nm of visible light and ensures that high transparent colors of products are not changed.

Description

technical field [0001] The invention belongs to the technical field of medicinal packaging materials, in particular to a novel medicinal glass molded bottle. Background technique [0002] At present, the development direction of the international bottle glass industry is safety and environmental protection. At the same time, bottle glass is facing severe challenges from new packaging materials such as metal and plastic. Therefore, bottle glass must give full play to its advantages of transparency, oxidation resistance, gas barrier, light-shielding, and UV cut-off. Since ultraviolet rays can decompose organic matter, resulting in limited shelf life of medicines, effective packaging products should be selected to effectively cut off ultraviolet rays to extend the validity period of the packaged items. [0003] The biggest feature that distinguishes glass packaging containers from other cans or paper containers is the transparency that allows the contents to be clearly seen. ...

AI Technical Summary

Problems solved by technology

Due to the difference in the process of bottle glass and flat glass, it is difficult for the coating process to be popularized and applied in the bottle glass industry

In the past, most pharmaceutical packaging in China used brown glass products to avoid ultraviolet rays. Although brown glass products have the function of cutting off ultraviolet rays, they are not beautiful in color. In the packaging of high-end biological agents and cosmetics, brown glass is almost not used Glass products are mostly packaged in colorless transparent glass, and general colorless transparent glass packaging products are transparent to ultraviolet rays and have no ultraviolet cutoff function.
