Abstract
The utility model relates to a medicinal flat-bottom rubber stopper, comprising a plug surface and a plug neck. The utility model is characterized in that three or more convex lines or spots are arranged at the external periphery of the needling circle; the medicine contact surface on the plug neck is a round plane. As for the utility model, because the three or more convex lines or spots are arranged at the external periphery of the needling circle and the medicine contact surface on the plug neck is designed into a round plane, on which a plurality of convex lines or spots can be arranged, the contact area between the plug surface and the medicine contact surface is reduced during rinsing; the rubber stoppers can not adhere to each other or the cleaning machine; the frictions among rubber stoppers are reduced so as to greatly reduce the scraps, grains and reduce the possibility of generating insoluble fine particles, ensure the product quality and rinsing effect, and improve the work efficiency; furthermore, because the needling circle on the plug surface is sunken, the rubber is saved; the puncturing force is reduced; the chips caused by puncturing is reduced; and the safety of the infusion product is improved in service.
Description
Technical field
This utility model relates to a kind of plug, particularly a kind of container that loads medicine seal medicinal flat 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 common plug comprises plug face and connected character cut in bas-relief or mouthful word open form plug neck, there is following defective in common plug: (1) is because common plug rub resistance not, friction is easy to generate buffings, micelle between chamber wall, plug and the plug of plug and cleaning machine in cleaning process, thereby has seriously influenced the quality of transfusion.(2) in cleaning the plug process, because the effect of air pressure and water, plug adheres to each other easily, causes and uses inconvenience.(3) 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, cleans in the plug process, can adherent mutually medicinal flat plug between the plug.
The purpose of this utility model is achieved in that this utility model comprises plug face and plug neck, and the acupuncture ring periphery on the described plug face is provided with the lines or the salient point of projection more than 3, and the medicine contact surface on the plug neck is a circular flat.
Also be provided with the lines or the salient point of projection more than 3 on the described medicine contact surface.
Described plug neck middle part is provided with anti-jump circle.
Described plug neck bottom is provided with the approaching face of gradient.
It is on the circumference at center that the lines of described projection or salient point are evenly distributed on plug face or medicine contact surface.
Described anti-jump circle 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 on the neck is designed to circular flat, and the lines or the salient point that can have projection, in cleaning process since have the projection lines or the support of salient point, plug can not stick together or be bonded on the cleaning machine like this, reduced the friction between the plug simultaneously, guarantee cleaning performance, improved work efficiency.
2, the acupuncture ring on the plug face can be economized glue to lower recess, reduces cost, and acupuncture thickness can be reduced in manufacture process, thereby reduce puncture force, reduces the issuable exfoliation of puncture, and infusion products safety in use is improved.
3, the acupuncture ring on the plug face is with the lines or the salient point of projection more than 3 outward, can reduce the friction between the plug in cleaning process, especially reduced the contact area between the plug face, can not adhere to mutually, cleaning performance is good, can effectively reduce the friction between plug and the chamber wall, has significantly reduced the generation of buffings, micelle, reduce the possibility that particulate matter produces, guaranteed the quality of product.
Description of drawings
Fig. 1 is a structural representation 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, the lines or the salient point 12 ' of projection, plug neck 2, anti-jump circle 21, medicine contact surface 22, approaching face 23.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail, but do not constitute any restriction of the present utility model.
Embodiment one
Please read Fig. 1, this utility model comprises plug face 1 and plug neck 2, acupuncture ring 11 outer lines or the salient points 12 that are with more than 3 on the plug face 1, general 3～5, can certainly more lines or salient point 12, it is on the circumference at center that lines or salient point 12 are evenly distributed on plug face 1, and the lines 12 of projection are the semicylinder short-terms.Medicine contact surface 22 on the plug neck 2 is circular flats, sees Fig. 2.
Embodiment two
Please read Fig. 1, this utility model comprises plug face 1 and plug neck 2, outside the acupuncture ring 11 on the plug face 14 salient points 12 is arranged, and it is on the circumference at center that salient point 12 is evenly distributed on plug face 1, and salient point 12 is hemisphere face or ellipsoid.Plug neck 2 middle parts are provided with anti-jump circle 21, and anti-jump circle 21 is parallel with plug face 1, and it is half-cylindrical that anti-jump circle 21 is, and highly is 0.3mm, and anti-jump circle 21 can prevent to jump the plug phenomenon, and makes sealing effectiveness better; Plug neck 2 bottoms are provided with the approaching face 23 of constant slope, can reduce resistance and prevent to jump the plug phenomenon in the process of jumping a queue.2 one-tenth miter angles of the gradient of approaching face 23 and plug neck.Medicine contact surface 22 on the plug neck 2 is circular flats, medicine contact surface 22 is provided with the lines or the salient point 12 ' of 3 projectioies, and general 3～5, can certainly be more, the lines or the salient point 12 ' of projection are evenly distributed on medicine contact surface 22 to be on the circumference at center, to see Fig. 2.
