Description

The plastic ampoule and the manufacture method thereof of medicinal liquid have been filled

Technical field

The present invention relates to a kind of plastic ampoule that is pre-charged with medicinal liquid.In more detail, relate to a kind of gas, light or medicine beyond the water vapour, water vapour (medicament, medicinal liquid, their solvent etc.) of can preventing and immerse or leach to ampoule is outside to ampoule is inner, the medicament that perhaps can prevent from ampoule, to hold, medicinal liquid, solvent etc. to the ampoule inner surface absorb, the plastic ampoule and the manufacture method thereof of the filling medicinal liquid of absorption.

Background technology

At present, the ampoule of receiving medical liquids is to use glass mostly.But glass ampule causes the dissolved problem of alkaline thin slice at the medicinal liquid pH Gao Shihui that holds.And the fragment of the danger of problem that finger is hurt easily when the ampoule of Kaifeng and ampoule breakage, generation when breaking a seal is sneaked into the problems such as danger in the medicinal liquid in addition.And then the danger that contained aluminum is dissolved in the medicinal liquid in glass ampule also appears in the warning of U.S. food pharmaceuticals office (FDA).Therefore, in recent years constantly with there not being the plastic ampoule of above-mentioned danger to replace.

General polyethylene (PE), the polypropylene polyolefin such as (PP) that flexibility is arranged and confirm safety that use of the plastics that form ampoule.PE and PP are to the acid and highly stable material of alkalescent medicine, but very high because of its absorption, permeability to oxygen, air, carbon dioxide etc., are not suitable as the formation material of the ampoule of the medicament that holds easy oxidation, medicinal liquid.Particularly under the situation of the ampoule of low capacity,, can produce the problem that liquor strength enlarges markedly because follow seeing through inner capacities and can reducing of moisture.

Therefore, the moulding material for blow molded products such as film shaped goods such as transfusion bag and infusion bottles is carrying out various researchs and is adopting the polylayer forest (laminated body) of giving the ability (barrier) that prevents in gas and the steam permeable container.

The laminated body of plastics extensively adopts when the manufacturing of thin film and thin plate, but because it is inappropriate using thin film or thin plate in the manufacturing of ampoule, must adopt blow molding in the manufacturing of ampoule.

The ampoule that forms according to blow molding is recorded in No. 2914826 communique of patent and the clear 60-24844 communique of Te Kai.The ampoule (health product container) of the former record is to use the goods of poly-cycloolefin blow molding, and the ampoule of latter's record (container that the inclosure injection medicament is used) is to have the anti-gas-bearing formation that made by the saponification resultant of ethylene-vinyl acetate copolymer (EVA) etc. the goods as the intermediate layer.

But, only put down in writing the theme that only forms ampoule in these documents by blow molding.And the sealing of ampoule is by after injecting medicinal liquid or dropping into medicament in these documents, seals this opening with the heat-sealing that does not produce joint, finishes sealing like this.In this case, have and when forming heat seal lands, follow the ruined worry of heating multiple structure, the incident worry that prevents that effect, effect such as gas permeation from suffering damage when its result has the multiple structure that adopts poly-cycloolefin and EVA.

On the other hand, other manufacture methods as the plastic ampoule of filling medicinal liquid can enumerate so-called blowing, fill, seal method (opens clear 33-8078 communique with reference to the spy, special public clear 36-5985 communique, the homepage of rommelag company " Welcome torommelag (R); " " BFS Process-The bottelpack (R) Process ", " retrieval on March 19th, 2003 ", the Internet＜URL; Http:// www.rommelag.com/ 〉).

Blowing, fill, the method for sealing is to form ampoule itself by the molten plastic parison of living tubular with main die clamp, after then filling medicinal liquid, carry out the formation and the sealing of ampoule head continuously with head mould, because the filling of the shaping of ampoule, medicinal liquid, the sealing of ampoule are carried out continuously, be the method that differs widely not only with only comparing with blow-moulding process, and can realize further that aseptic medicinal liquid injects, having can mass-produced advantage.

But, by blowing, the ampoule of filling, sealing manufactured is well known that the individual layers by polyolefin prepared such as PE and PP.Thereby, existing situation be for by blowing, fill, seal the ampoule of manufactured multiple structure, and 1 floor that forms this laminated construction for gas, water vapour, light and medicine prevent the ability (barrier) that sees through and to the ability that prevents of the absorption absorption of medicine all without any correlational study (with reference to the homepage of special public clear 33-8078 communique, special public clear 36-5985 communique, aforesaid rommelag company, the homepage of mutual company (" packaging facilities-container be shaped aseptic fill system ", " retrieval on March 19th, 2003 ", the Internet＜URL; Http:// www.mutual.co.jp 〉), homepage (" polyethylene bottle ", " retrieval on March 19th, 2003 ", the Internet＜URL of Ri Xin drugmaker; Http:// www.yg-nissin.co.jp/BFS.htm 〉)).

For give to gas, water vapour, light and medicine prevent see through (barrier), to the ability that prevents of drug absorption absorption, for example consider to have and in having the bag of gasproof body permeability, hold the preservation ampoule, or prevent that with having the material that light sees through ability (light barrier) from covering the ampoule surface, or the method for carrying out outer package.But these methods must separately be used the material of bag container and covering surfaces, thereby manufacturing step becomes complicated, have problems such as manufacturing cost rising.
