Method for machining crooked neck nicking color ring easy-to-break ampoule

Abstract

The invention discloses a method for machining a crooked neck nicking color ring easy-to-break ampoule. The method specifically includes that (1) annular nicking is performed at a position of crooked neck of the ampoule, and the nicking length is at least 30% of perimeter of the crooked neck of the ampoule; (2) colored glaze covers a nicking position; (3) the colored glaze is subjected to annealing and sintering. According to the method for machining the crooked neck nicking color ring easy-to-break ampoule, traditional point nicking of the crooked neck ampoule is changed to continuous nicking, controlling is convenient and accurate, the process is quite simple, meanwhile, the colored glaze covers long nicking position for connection into a whole during breaking, then the problem that chips of glass are generated due to long nicking and together breaking during breaking is solved, a breaking surface is quite smooth, usage is quite safe, the colored glaze does not have breaking stress function, factors that are hard to control and directly affect breaking force, such as coefficient of linear thermal expansion and temperature of the colored glaze, are not required to be considered as long as the appearance is bright and attractive, the process is quite simple, meanwhile, dirt accumulation and residuals of chips of glass in cuts of the nicking position can be perfectly avoided, and the method is quite sanitary and safe.

Description

technical field [0001] The invention relates to the field of pharmaceutical packaging materials, in particular to a processing method for an easy-break ampoule with a curved neck scoring color ring. Background technique [0002] According to the YBB national pharmaceutical packaging container (material) standard, there are currently two easy-folding methods: a little notch and a color ring. The color ring easy-to-break ampoule is a line of expansion coefficient greater than the ampoule itself 2×10 at the curved neck of the ampoule -6 K -1 The low-melting point glass color glaze ring is melted on the neck of the ampoule at a certain temperature. Due to the difference in the linear thermal expansion coefficient between the color ring and the ampoule itself, stress is generated, which plays a role of easy folding and has a smooth cross-section. In actual production Due to the influence of the deviation of the outer diameter and thickness of the ampoule neck, the thickness of ...

Problems solved by technology

The ampoule is not easy to break and the section is uneven. On the one hand, it is easy to produce more glass debris, which seriously affects the safety of drug use. On the other hand, it is easy to cause injuries to nurses, so the easy-to-break ampoule is not easy to break and the uneven section seriously affects the safety of the ampoule.
