Abstract
The utility model relates to a medical rubber cork with a filmed cork neck, which is provided with a rubber cork comprising a main body and a cork neck. A film is covered on the circumferential wall and the undersurface of the cork neck except on the sealing surface. A film is arranged on two-thirds of the circumferential wall and whole undersurface of the cork neck in the utility model. The undersurface of the cork neck in the utility model can be a plane, a contour or other shapes. The cork neck in the utility model can be circular cylinder or other shapes. The sealing surface refers to the surface part of the main body of the cork except the cork neck. The utility model has the advantages that: the film is covered only on surface of the cork which is contacted with the medicine, thus totally solving the possible compatible problem caused by the direct contact of the rubber cork with the medicine. At the same time, the sealing surface has no film so as to ensure the sealing function of the rubber cork.
Description
Technical field
This utility model relates to bottle closure of rubber, mainly relates to a kind of medicinal rubber bottle stopper of filling in the neck overlay film.
Background technology
Medicinal rubber bottle stopper must have excellent air-tightness, good chemical stability and biologically inert as a kind of encapsulant of direct contact medicine, guarantees on the one hand to be hedged off from the outer world in order to avoid medicine generation oxidation or deliquescence etc. lost efficacy rotten; On the other hand, medicinal rubber bottle stopper itself can not react to each other with medicine and influence the medicine quality.
Existing material of producing the medicinal rubber bottle stopper use mainly contains natural rubber (NR), polyisoprene rubber (IR), butyl rubber (IIR) and halogenated butyl rubber (HIIR).Under normal conditions, add multiple compounding ingredient and adopt the mould pressing process manufacturing.All there is the chemism that has nothing in common with each other in various compounding ingredients in the cooperation system of support formation plug characteristic, plug with direct contact of medicine in, have chemically active material and medicine generation chemical reaction in the prescription, the result of these chemical reactions has directly influenced stability of drug.So strictly speaking, the extractable matter of plug is not that the problem that does not have is arranged to the influence of medicine stability, but with having how much to measure medicine is brought pollution how long.Simultaneously, because the activity difference of medicine itself is very big, emerging in an endless stream of new drug in addition, so up to the present, medicinal rubber bottle stopper is limit by material material and prescription level, does not also have a kind of prescription of uniqueness can satisfy all pharmaceutical preparation.Here it is elastomer pharmaceutical pack material with direct contact of medicine in the compatibility or suitability problem.
In the consistency problem of existing film coating technique in having solved direct contact of bottle stopper and medicine, but influenced the adaptation between bottle stopper and the glass bottle opening, promptly influenced sealing function medicine.Because existing film coating technique, no matter two-sided or single face cover, and all with the sealing surface of bottle stopper also overlay film, the bright finish lubricating effect of film just has a strong impact on the effect that utilizes caoutchouc elasticity seal glass bottleneck like this.
Summary of the invention
This utility model provides a kind of medicinal rubber bottle stopper of filling in the neck overlay film just in order to solve the consistency problem of above-mentioned bottle stopper and medicine.
This utility model solves the technical scheme that its technical problem adopts: the medicinal rubber bottle stopper of this plug neck overlay film, comprise bottle stopper, described bottle stopper mainly is made up of bottle stopper main body and plug neck, being covered with rete on the circumferential wall of plug neck and on the bottom surface of plug neck, is not covered with rete on sealing surface.
This utility model is being covered with rete on the circumferential wall of plug neck 2/3rds and on the bottom surface of plug neck.
The bottom surface of plug neck described in the utility model can be a plane, also can be an arc surface or other shapes.
Cylindrical or other shapes of plug neck described in the utility model.
Sealing surface described in the utility model is meant the part of removing the plug neck on the surface of bottle stopper main body.
The effect that this utility model is useful is: only with bottle stopper with medicine contact surface plug neck overlay film, solve contingent consistency problem in direct contact of medicinal rubber bottle stopper and medicine fully, the while sealing surface is overlay film not, has guaranteed the due sealing function of medicinal rubber bottle stopper.

The specific embodiment
Below in conjunction with drawings and Examples this utility model is described in further detail.
Embodiment 1: as shown in Figure 1, the medicinal rubber bottle stopper of this plug neck overlay film comprises bottle stopper 1, described bottle stopper 1 mainly is made up of bottle stopper main body 1-2 and plug neck 1-1, be covered with rete 2 on the circumferential wall of plug neck 1-1 and on the bottom surface of plug neck 1-1, overlay film is no more than A, D, but near A, D point; On sealing surface 3, be not covered with rete 2.1-1 is cylindrical for plug neck 1-1 plug neck, and its bottom surface is a plane, and described sealing surface 3 is meant the part of removing plug neck 1-1 on the surface of bottle stopper main body 1-2.
After being installed on the bottle 4, bottle stopper 1 as shown in Figure 3, guarantees bottle stopper plug neck 1-1 overlay film and sealing surface 3 overlay film not.Promptly along ABCD face overlay film, and overlay film is no more than A, D.
Embodiment 2: as shown in Figure 2, difference from Example 1 is: the bottom surface of plug neck 1-1 is an arc surface.
Embodiment 3: as shown in Figure 4, difference from Example 1 is: be covered with rete on the circumferential wall of plug neck 2/3rds and on the bottom surface of plug neck, overlay film surpasses B, C point on the position of plug neck 2/3rds, preferentially will be more than 1/2nd, and the best is more than 2/3rds.
