Abstract

The utility model belongs to the technical field of pharmaceutical packaging, discloses a laminated anti-jump cork, and aims at solving the problem that in the process of bottling of drugs, rubber corks jump up, and therefore the drugs are polluted. The laminated anti-jump cork comprises a cork crown (1) and a cork neck (3), wherein the outer wall surface of the cork neck (3) is a tapered surface (4), the diameter of the outer wall of the cork neck (3) becomes longer from the root portion to the end portion, the inner wall of the cork neck (3) is coated with a polyester film (5), the outer wall of the cork neck (3) is coated with a polyester film (5), and a protrusion (2) is arranged on the upper surface of the cork crown (1). The laminated anti-jump cork can be widely used in bottling and sealing of infusion, antibiotics and lyophilized preparation.

Description

The multiple anti-jump bottle stopper of film

Technical field

The utility model relates to a kind of for medicinal bottle stopper, particularly a kind of multiple anti-jump bottle stopper of film.

Background technology

The medicinal rubber bottle stopper of selling in the market, be mainly used in the bottled sealing of infusion solutions, microbiotic and lyophilized formulations, because bottle closure of rubber and the contacted plug neck of bottleneck internal face are cylindric, when medicine pack into bottle and cover plug after, bottle closure of rubber can be gone out bottleneck because of concussion and upspring and jump out the canned speed of medicine that affected; This bottle stopper and exist the compatible problem of medicine in elastomeric material and the bottle; the oxious components such as the vulcanizator in the rubber, accelerator, extending agent, plasticizer; after autoclaving is processed and is deposited a period of time; bottle closure of rubber inside can discharge above-mentioned ingredients substance; the particulate on bottle closure of rubber surface can come off; thereby cause medicine pollution, cause drug quality to reduce and short problem of quality guarantee period of medicament phase.

Summary of the invention

The utility model overcomes deficiency of the prior art, provide a kind of when medicine is canned plug do not jump and prevent the anti-jump bottle stopper of multiple film of medicine pollution.

In order to solve the problem of above-mentioned technology, the utility model is achieved through the following technical solutions: the multiple anti-jump bottle stopper of film comprises plug hat and plug neck, and plug neck outside wall surface is the gradually conical surface of large shape from root to the end, on the inside and outside wall of plug neck polyester film is arranged again.

The utility model also can be achieved through the following technical solutions: the above plug is labeled the surface and is provided with projection.

The utility model can also be achieved through the following technical solutions: the projection that the above plug is labeled the surface is circle shape, short-term shape and muscle shape.

Compared with prior art, the beneficial effects of the utility model are: improved the canned efficient of medicine, improved drug quality and the shelf-life that has prolonged medicine, guaranteed the people's drug safety.

Description of drawings

Fig. 1 is cross-sectional view of the present utility model.

Fig. 2 is the schematic top plan view of Fig. 1.

In the accompanying drawings: 1-plug hat, 2-projection, 3-plug neck, the 4-conical surface, 5-polyester film.

The specific embodiment

Below in conjunction with the drawings and specific embodiments the utility model is described in further detail: the multiple anti-jump bottle stopper of film comprises plug hat 1 and plug neck 3, plug neck 3 outside wall surface are the gradually conical surface 4 of large shape from root to the end, on the inside and outside wall of plug neck 4 polyester film 5 is arranged again, plug hat 1 upper surface is provided with round shape projection 2.

Owing on the inside and outside wall of plug neck 4 polyester film 5 being arranged again, effectively prevented the compatible of elastomeric material and the interior medicine of bottle, avoided bottle closure of rubber to medicine pollution, improved the shelf-life of medicine; Because plug neck 3 outside wall surface are the gradually conical surface 4 of large shape from root to the end, thus prevented when medicine is canned bottle closure of rubber go out bottleneck upwards spring improved the canned speed of medicine; Because plug hat 1 upper surface is provided with round shape projection 2, after mutual extruding, produce adhesion thereby solved bottle closure of rubber, the problem of impact cleaning and sterilisation quality has improved product design and has prolonged the shelf-life.

Claims
