Problems solved by technology

This method is complex in process and increases in cost. Due to the influence of the outer diameter and thickness of the ampoule neck, the effect of applying to ampoules of 5mL and above is not ideal.
Compared with the color ring ampoules, dot-scored curved-neck glass ampoules have a wider range of applications. Due to the unreasonable design of the neck shape of traditional curved-neck flexible glass ampoules, curved-neck flexible glass ampoules are not easy to break and have uneven cross-sections, especially for 5mL The phenomenon of glass ampoules with specifications above and above is obvious, and it is very easy to cause glass punctures on the hands of the operator during the breaking operation of the ampoule, resulting in potential cross-infection and the glass debris generated during the breaking process enters the human blood during intravenous administration. Serious medical risks such as circulatory system

Abstract

The invention relates to a bent-neck easy-to-break glass ampoule which comprises an ampoule bottom, an ampoule body, an ampoule body shoulder, a neck portion, a soaking portion and a threaded portion sequentially arranged from bottom to top. The bent-neck easy-to-break glass ampoule is technically characterized in that best fitting radius R1 of a connecting arc of the neck portion and the soaking portion is 1.2-3.0mm. The bent-neck easy-to-break glass ampoule has the advantages of simple processing technique, wide application range, low modification degree on existing equipment, attractive appearance, convenience in filling and sealing operation, easiness in breaking and higher section flatness.

Description

technical field [0001] The invention belongs to the technical field of medicine packaging materials and containers, and in particular relates to a bend-neck easy-break glass ampoule. Background technique [0002] According to the YBB national standard for pharmaceutical packaging container materials, glass ampoules are currently divided into dot-marked curved-neck easy-fold glass ampoules and color ring curved-neck easy-fold glass ampoules. The color-ring curved neck easy-fold glass ampoule is a line added to the curved neck of the ampoule The thermal expansion coefficient is greater than that of the glass colored glaze ring made of ampoule glass. After the annealing process, the colored glaze ring is melted on the neck of the ampoule. Because the linear thermal expansion coefficient of the colored glaze ring is different from that of the ampoule glass material, stress is generated on the neck of the ampoule, thus It plays the role of easy folding and neat section. This met...
