High-strength borosilicate glass tube-made injection bottle and production process thereof

Abstract

The invention discloses a high-strength borosilicate glass tube-made injection bottle and a production process thereof. The injection bottle comprises a protective shell; a first limiting ring is fixedly arranged at the top end of the outer wall of the protective shell, a heat preservation inner container is arranged on the inner wall of the protective shell in a sleeving mode, a positioning ring is fixedly arranged at one end of the outer wall of the heat preservation inner container, and the bottom end of the positioning ring makes contact with the top end of the first limiting ring; first sliding strips are arranged at the four corners of the top of the outer wall of the heat preservation inner container correspondingly, first sliding grooves are formed in the four first sliding strips correspondingly in a sliding mode, and the four first sliding grooves are formed in the four side edges of the inner wall of a protection cap correspondingly. By clamping the heat preservation inner container on the top of the protective shell, the high-strength borosilicate glass tube-made injection bottle achieves the sealing effect; due to layered heat insulation, a heat preservation and protection effect is achieved on a small amount of medicine not prone to sudden change at the special temperature, the characteristics of the medicine are protected, and the practicability of the high-strength borosilicate glass tube-made injection bottle is improved.

Description

technical field [0001] The invention relates to the field of high-strength borosilicate glass control injection bottles, in particular to a high-strength borosilicate glass control injection bottle and its production process. Background technique [0002] According to the requirements of the standard formulation, the standards for pharmaceutical packaging materials should be divided according to the material, one standard for one material (variety), and the standard name for high-strength borosilicate glass control injection bottles should follow the sequential format of material, application, and shape. Therefore, this standard The name of the high-strength borosilicate glass control injection bottle is proposed. High-strength borosilicate glass control injection bottle is recognized as the best pharmaceutical packaging material in the world today. It has stable chemical properties, water resistance, acid resistance, and alkali resistance. Class A, with strong thermal shock...

AI Technical Summary

Problems solved by technology

[0003] In the prior art, high-strength borosilicate glass control injection bottles are usually made of transparent single-layer borosilicate glass, so in the process of use, it is difficult to provide heat preservation protection for a small amount of drugs that are not suitable for sudden changes in special temperature. It not only reduces the characteristics of the drug, but also reduces the practicability of the high-strength borosilicate glass control injection bottle, so a high-strength borosilicate glass control injection bottle is needed
