Embodiment Construction

[0020] A feature of the present invention is that the inner plug is formed by molding, and then the inner plug and the rubber material used to form the outer plug are placed in a mold for vulcanization to form the final composite rubber plug. During the vulcanization process, the inner plug and the outer plug are tightly combined into one. And the molding method is very simple.

[0021] The molding method used in the present invention is injection molding.

[0022] Preferably, after the inner plug is formed, the surface of the inner plug is subjected to physical or chemical treatment to remove dirt on the surface and / or activate the surface so that the surface can easily interact with the rubber material.

[0023] The materials used to form the inner plug are known in the prior art, such as the aforementioned film-forming materials that do not easily interact with drugs. The temperature and time of vulcanization should be selected according to the characteristics of rubber a...

Abstract

The invention relates to a method for producing a bottle cork used for medicament packaging. The related bottle cork is formed by compounding an inner cork and an outer cork, wherein the inner cork has a shell shape and covers the surface, facing medicaments, of the outer cork. The method comprises the steps of: forming the inner cork by injection molding; and placing the inner cork and a rubber composition for forming the outer cork into a die and performing vulcanization to form the rubber bottle cork. The method can simply, conveniently and efficiently produce rubber bottle corks.

Description

technical field [0001] The invention relates to the field of packaging, in particular to a production method for plastic bottle stoppers used in medicine bottles and the plastic bottle stoppers produced by the method. Background technique [0002] Pharmaceutical manufacturers often use packaging similar to vials to package liquid or solid drugs, and the stoppers are usually rubber stoppers. During storage and transportation, the rubber stopper will always come into contact with the medicine in the bottle. Since the components of the rubber stopper contain rubber, vulcanizing agent, vulcanization accelerator, filler, plasticizer and protein molecules, some of them will physically or chemically interact with the drug components, which will eventually contaminate the drug. Especially some cephalosporins, some large infusions and many traditional Chinese medicine injection preparations, etc., often have drug quality problems caused by bottle stoppers. [0003] In order to solv...
