Embodiment Construction

[0017] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.

[0018] figure 1 Shown: a kind of processing method of curved neck scoring color ring easy to break ampoule, concrete steps are:

[0019] 1. A high-speed rotating knife is used to score one week at the curved neck of the ampoule, where the width of the score is 0.2mm and the depth is 0.05mm. When the bottle passes through the high-speed scoring motor, the neck is in natural contact with the high-speed rotating scoring knife and rotates 100% of the time. Even if the outer diameter of the neck deviates by 2mm, the scoring knife can naturally fit the scoring through the leverage of the counterweight. The width is 0.2mm, the depth is 0.05mm, and the length is one week. The cuts are uniform, stable and consistent, and no additional control mechanism is required;

[0020] 2. Cover the notch with a layer of colored glaze with a width great...

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 ...
