Abstract
The utility model relates to a rubber stopper with covering film for medical use which comprises a stopper face, a stopper neck and the film on the surface of stopper. Beyond the needle punched ring on the surface of the stopper is provided with at least three protruding lines or dots. The utility model not only keeps the advantages of other covering films or film-plating stoppers but also has better airproof function than the ordinary rubber stoppers with covering film and avoids the bad effect on the quality of medicine caused by the falling of plating film. The utility model is characterized in its good airproof function and in that rubber stoppers will not adhere to each other when they are washed.
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 around whole plug and sealing surface and medicine contact surface, answer film or plated film, there is following defective in the plug of multiple 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 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.
Summary of the invention
The purpose of this utility model just provides a kind of good seal performance, the plated film difficult drop-off, and in the cleaning process, can adherent mutually medicinal overlay film plug between the plug.
The purpose of this utility model be achieved in that this utility model comprise plug face, plug neck and on overlay film, the lip-deep acupuncture ring of described plug face has more than 3 the lines or the salient point of projection outward at least.
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.
Above-mentioned medicinal overlay film plug is described to be provided with overlay film in the medicine contact surface.
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, 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.
3, 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.
4, only be covered with macromolecular material, and the sealing surface on part that contacts with bottleneck and the anti-jump circle of bottleneck all there is not overlay film, so that plug and bottleneck have good sealing property at approaching face and the medicine contact surface of filling in neck.
5, 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.
6, 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.
7, 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.
8, 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.
Description of drawings
Fig. 1 is a front view of the present utility model.
Fig. 2 is a profile of the present utility model.
In the drawings, plug face 1, acupuncture ring 11, the lines or the salient point 12 of projection, plug neck 2, anti-jump circle 21, medicine contact surface 22, approaching face 23, overlay film 3.
