Combined cover for injection medicine bottle

Abstract

The invention discloses a combined cover for an injection medicine bottle, which comprises a plastic primary cover capable of being arranged at the bottle opening, wherein the plastic primary cover is provided with an opening over against a bottle opening sealing rubber plug, a plastic secondary cover which can be opened to be separated from the plastic primary cover is covered above the plastic primary cover, and a sealing connecting structure is arranged between the plastic secondary cover and the opening of the plastic primary cover. The invention aims to overcome the defects of the prior art and provide the combined cover for the injection medicine bottle, which has the advantages of simple structure, material economization, low cost, good sealing effect and high quality.

Description

[technical field] [0001] The invention relates to a combination cap for an injection medicine bottle. [Background technique] [0002] For a long time, medical injection bottles have been sealed with aluminum caps or aluminum-plastic composite caps and rubber stoppers through capping and closing processes. However, aluminum chips are often attached to aluminum caps after processing, which can easily pollute the environment during the capping process, thereby affecting the safe use of medicines. The aluminum-plastic composite cap is a combination of two parts made of two materials. Generally, the lower side is an aluminum cap and the upper side is a plastic cap. The aluminum cap wraps the rubber plug and closes at the lip of the bottle, while the plastic cap and The middle part of the upper side of the aluminum cover is connected, and there is a ring-shaped gap on the aluminum cover. When in use, the plastic cover is lifted up, and the plastic cover will tear the middle part ...

However, aluminum chips are often attached to aluminum caps after processing, which can easily pollute the environment during the capping process, thereby affecting the safe use of medicines

The aluminum-plastic composite cap is a combination of two parts made of two materials. Generally, the lower side is an aluminum cap and the upper side is a plastic cap. The aluminum cap wraps the rubber plug and closes at the lip of the bottle, while the plastic cap and The middle part of the upper side of the aluminum cover is connected, and there is a ring-shaped gap on the aluminum cover. When in use, the plastic cover is lifted up, and the plastic cover will tear the middle part of the aluminum cover, exposing the middle part of the rubber plug for convenience. For injection needle penetration, this kind of cap uses more materials. The whole process is time-consuming, laborious, and space-consuming during processing. The processing cost is high, and the capping and connection procedures are complicated. In addition, injection medicine bottles are generally made of glass, and glass products cannot be as standard as molded or machined products after they are made, especially the inner and outer diameters of the bottle mouth and the height of the bottle mouth. The error is relatively large, so there are always differences in the combination with aluminum caps or aluminum-plastic composite caps. The combination is not very good, which affects the sealing effect, which in turn has a negative impact on the quality and use of medicines.
