Abstract
The utility model relates to a coated medicinal rubber stopper, comprising a stopper face and a stopper neck. The utility model is characterized in that at least more than 3 convex lines or convex points are disposed outside the acupuncture ring at the surface of the stopper face, and a coating film is disposed on the surface of the stopper face. The utility model can not only maintain advantages of other coated or plated rubber stoppers, but also has better sealing performance than ordinary coated rubber stoppers and avoids the plating film from falling off to influence medicine quality. The coating film disposed on the surface of the stopper face can increase the cleanliness of the stopper face and prevent the steam from entering the concave part of the stopper face during infusion and sterilization. Because when the steam cools, water will remain at the concave part of the stopper face, which is easy to breed microbes during storage and transportation and influences medicine quality.
Description
Technical field
This utility model relates to a kind of medical rubber plug, particularly a kind of container that loads medicine seal plug.
Background technology
Because medicinal rubber bottle stopper is the main sealed piece of bottled medicine and derives part that it has utilized the distinctive elasticity of rubber, thereby makes medicine realize reliable sealing, for the storage and the use of medicine are provided convenience.At present, widely used plug comprises plug face and connected character cut in bas-relief or mouthful word open form plug neck, for the medicine that is seated in the bottle is not directly contacted with plug, can be at the overlay film or the plated film all around of whole plug and sealing surface and medicine contact surface, there is following defective in the plug of overlay film or plated film: (1) sealing is relatively poor, jump plug in the process of jumping a queue easily, in transportation and behind the encapsulated drug, rete easily comes off as coated plug.(2) because common plug rub resistance not, friction is easy to generate buffings, micelle in cleaning process and between chamber wall, plug and the plug, thereby has seriously influenced the quality of transfusion.(3) in cleaning the plug process, because the effect of air pressure and water, plug adheres to each other easily, causes and uses inconvenience.(4) common plug contact surface with medicine in bottle is bigger, and the leachable amount is also more, has influenced stability of drug.(5) common plug face up concave type plug is sterilized behind encapsulated drug, and water vapour can enter the recessed part of plug face, and moisture entrapment is arranged after the cooling, in the medicine transporting procedures, is easy to generate microbial growth, thereby influences the quality of medicine.
Summary of the invention
The purpose of this utility model just provides a kind of good seal performance, and the rete difficult drop-off cleans in the plug process, can not adhere to mutually between the plug, and behind the encapsulation medicine, the recessed portion on plug surface is difficult for growing the medicinal overlay film plug of microorganism.
The purpose of this utility model is achieved in that this utility model comprises plug face and plug neck, and the lip-deep acupuncture ring of described plug face has the lines or the salient point of projection more than 3 outward at least, and plug face surface is provided with overlay film.
The described plug neck of above-mentioned medicinal overlay film plug middle part is provided with anti-jump circle.
The above-mentioned described plug neck of medicinal overlay film plug bottom is provided with the approaching face of gradient.
The medicine contact surface of the described plug neck of above-mentioned medicinal overlay film plug bottom is a circular flat.
The above-mentioned described approaching face of medicinal overlay film plug is provided with overlay film.
The above-mentioned described medicine contact surface of medicinal overlay film plug is provided with overlay film.
It is on the circumference at center that the lines of the above-mentioned described projection of medicinal overlay film plug or salient point are evenly distributed on the plug face.
The above-mentioned described salient point of medicinal overlay film plug is hemisphere face or ellipsoid.
The above-mentioned described anti-jump circle of medicinal overlay film plug is parallel with the plug face.
This utility model is compared with existing plug, has following advantage:
1, the medicine contact surface that will fill in neck bottom is designed to circular flat, reduced the contact area of plug and medicine, reduce the interaction of plug content and medicine, there is not dead angle not easy to clean in the contact surface of plug and medicine simultaneously, impurity and particulate matter that plug brings have been reduced, improve the clarity of product to a certain extent, improved the compatibility of plug and medicine, prolonged the effect duration of medicine relatively.
2, on plug face surface, be provided with overlay film, the generation that can reduce micelle increases the cleanliness factor on plug surface, in the time of can also preventing because of the transfusion sterilization, the recessed part of plug face has water vapour, after the water vapour cooling, the recessed part of plug face has moisture entrapment, grows microorganism in transporting procedures easily, thereby has influenced the quality of medicine.
3, the medicine contact surface in plug neck bottom is provided with overlay film, directly contacts with plug in order to prevent the medicine that is seated in the bottle, effectively intercepts the plug content and is extracted by medicine, has guaranteed the quality of medicine
4, the acupuncture ring on the plug face can be economized glue to lower recess, reduces cost, and acupuncture mouth thickness can be reduced in manufacture process, thereby reduce puncture force, reduces puncture exfoliation number, and infusion products safety in use is improved.
5, approaching face and the medicine contact surface at the plug neck is covered with macromolecular material, and the sealing surface on part that contacts with bottleneck and the anti-jump circle of bottleneck is equipped with overlay film, so that plug and bottleneck have good sealing property.
6, adopt post forming, overlay film is embedded in the anti-jump circle of plug neck, can prevent that the overlay film pull-up from falling.
7, the middle part of plug neck is provided with anti-jump circle, can prevent to jump the plug phenomenon in the process of jumping a queue.
8, the lines or the salient point that outside the lip-deep acupuncture ring of plug face, have projection more than 3 at least, can reduce in cleaning process, friction between the plug, especially reduced the contact area between the plug face, can not adhere to mutually, cleaning performance is good, can effectively reduce the friction of plug and chamber wall, significantly reduce the generation of buffings micelle, reduced the possibility that particulate matter produces, guaranteed the quality of product.
9, the approaching face of plug neck bottom is made the lead angle of constant slope, can reduce resistance and prevent to jump the plug phenomenon in the process of jumping a queue.
