Abstract
A rubber plug partially coated with polyolefin film comprises a rubber plug, and a layer of the polyolefin thin film is arranged on the contacting surface between the rubber plug and drugs. The rubber plug is a halogenated butyl rubber plug, and the rubber plug and the polyolefin thin film are combined into a whole by means of vulcanization. Due to the fact that a layer of the polyolefin thin film is arranged on the contacting surface between the rubber plug and drugs, the rubber plug can be separated from the drugs through the polyolefin thin film. Further, excellent performances of the polyolefin thin film, such as high temperature resistance, acid and alkali resistance, chemical corrosion resistance, organic solvent resistance, stress crack resistance and the like, can protect the stability of the drugs and satisfy the compatibleness of the rubber plug and the drugs.
Description
Technical field
This utility model relates to a kind of overlay film plug, and the polyolefin film plug is covered in the particularly a kind of part that can satisfy the medicine and the plug compatibility.
Background technology
The overlay film plug has obtained using widely at field of medicaments, after plug and medicine contact surface adhere to the inert membrane, plug and medicine is isolated, and can reduce the pollution that plug brings to medicine.The overlay film plug that uses both at home and abroad mainly is Teflon film and dacron membrane with film at present.Cover Teflon film plug cost of manufacture height, cost an arm and a leg, be unfavorable in drug packaging is used, extensively promoting; Dacron membrane need pass through pretreatment before use, complex manufacturing technology, and cover the dacron membrane plug through cleaning, and behind the high temperature sterilize, be prone to the film dropping situations, thereby influence drug quality, be detrimental to health.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of part and covers the polyolefin film plug, and cost is low, and processing technology is simple, can keep stability of drug products, and is safe.
For solving the problems of the technologies described above, the technical scheme that this utility model adopted is: the polyolefin film plug is covered in a kind of part, comprises plug, has one deck polyolefin film at plug and medicine contact surface.
Plug is the halogenated butyl rubber plug.
Be combined into an integral body by vulcanization between plug and the polyolefin film.
The polyolefin film plug is covered in the part that this utility model provides, and beneficial effect is as follows:
1, owing to has one deck polyolefin film at plug and medicine contact surface; polyolefin film separates medicine and plug; polyolefin film has the high temperature resistant of excellence; acid and alkali-resistance; resistance to chemical attack, organic solvent-resistant, performances such as stress crack resistant; can protect stability of drug, satisfy the compatibility performance of plug and medicine.
2, polyolefin and halogenated butyl rubber cross-linked structure are stable, make that overlay film intensity height, high temperature washing and sterilizing also do not influence overlay film intensity, and be safe behind polyolefin film and the plug overlay film.
3, other overlay film plugs relatively, the polyolefin film processing technology is simple, and cost is low, is convenient to promote the use of in various drug packagings, is particularly useful for aqueous injection, injectable powder, injection, lyophilized formulations medicine.
Description of drawings
The utility model is described in further detail below in conjunction with drawings and Examples:
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
As shown in Figure 1, this utility model comprises plug 1, has one deck polyolefin film 2 at plug 1 and medicine contact surface.
Be combined into an integral body by vulcanization between plug 1 and the polyolefin film 2.
Manufacture process of the present utility model is as follows:
Polyolefin film 2 is tiled on the in type butyl film that mixes in advance, then the butyl film is put into vulcanizing press and vulcanize, depanning, flash trimming promptly gets the local polyolefin film plug that covers.
Claims (3)
