Problems solved by technology

[0003] During the implementation of the national trial standard, it was found that due to better control of the content of residue on ignition, although the content of medicinal rubber has increased relatively, the hardness of the rubber stopper will decrease accordingly. On the one hand, it has caused pharmaceutical companies to use During the process, the probability of putting the rubber stopper on is reduced. On the other hand, if the drug is not properly punctured during clinical use, the rubber stopper can easily be inserted into the bottle.
As far as the performance of the rubber stopper is concerned, the hardness is an important control item that cannot be ignored. If the hardness of the r

Embodiment Construction

[0007] The following is a further description of the patent skeleton pharmaceutical rubber plug of the present invention according to the accompanying drawings.

[0008] Referring to FIG. 1 , a schematic diagram of the patent skeleton medical rubber stopper covered with rubber of the present invention includes a skeleton stopper 1 and a medicinal elastomer material 2 .

[0009] Referring to Fig. 2, it is a skeleton plug 1 in the patent of the present invention, which consists of a plug top 3 and a plug body 4. There is a puncture hole 5 in the middle of the plug top 3, a fixing groove 6 in the middle of the plug top 3, and an inner rubber hole in the middle of the plug top 3. 7. The plug top 3 is extended with an outer glue hole 8.

[0010] Its manufacturing method 1 is the flat-plate molding vulcanization method: firstly, the corresponding skeleton plug is manufactured, and after a certain treatment, the skeleton plug is put into and fixed in the lower mold of the steel mold,...

Abstract

The present invention is one kind of medicinal rubber stopper with skeleton and its making process. The medicinal rubber stopper has a stopper skeleton coated with medicinal elastic material. It is made through one of three making processes, plate molding and vulcanizing process, one-step plate molding and vulcanizing process and injection molding process. The medicinal rubber stopper with skeleton has the advantages of high rubber content, high sealing performance, low cost, high hardness, high needle prick resistance, high heat resistance, etc.

Description

technical field [0001] The invention relates to a medicinal rubber stopper, in particular to a medicinal rubber stopper comprising a skeleton plug. Background technique [0002] With its unique chemical stability, excellent sealing and self-sealing properties, and high-temperature disinfection performance, medicinal corks provide a guarantee for the preservation of pharmaceutical packaging. However, rubber has no elasticity, only plasticity, and is easy to be molded into any shape. In order to endow medical rubber stoppers with suitable physical properties such as hardness, strength and tear strength, and meet the requirements of pharmaceutical production and clinical use, an appropriate amount must be added to its main material. Additives and fillers based on inorganic materials are of value only after vulcanization process hardens to form cork products. Such substances account for about 50% of the overall formula. The national standard stipulates that it should not exceed...
