Abstract
The utility model discloses a rubber plug which comprises an upper part and a lower part, and the upper part and the lower part are made of different materials. A T-shaped clamping tenon is arranged on the lower part, a bayonet matched with the clamping tenon is formed in the lower portion of the upper portion, the upper part and the lower part are connected through a clamping tenon structure, therefore binding force between the upper part and the lower part is increased, the rubber plug is not prone to disengagement, and use of medicine liquid cannot be influenced.
Description
Technical field
This utility model relates to a kind of rubber stopper, particularly a kind of rubber stopper of foreign material structure.
Background technology
The sealed piece that rubber stopper is bottled or bagged liquid is important.Because will contact with medicinal liquid, the material requirements of rubber stopper is the material with good biological or chemical compatibility, but this material price is higher, makes production cost improve.In order to reduce production costs, rubber stopper is designed to the structure of foreign material, with the medicinal liquid contact portion be the material with good biological or chemical compatibility, and other the part lower common natural or synthetic rubber that is price.
But two part contact surfaces can cause separating between the two because the compatibility between different materials is different, affect the normal use of medicinal liquid.
The utility model content
This utility model purpose is: provide xenogenesis to improve the rubber stopper of two foreign material interface binding powers.
The technical solution of the utility model is: a kind of rubber stopper, comprise upper and lower, and both interconnect with Fastening tenon structure.
Preferably, bottom is provided with trip, on offer the bayonet socket of coupling.
Preferably, the section shape of described trip is the T font.
The utility model has the advantages that: utilize the structure of trip and bayonet socket on adhesion, to do the physical property enhancing, make difficult drop-off between two foreign materials.
The accompanying drawing explanation
Below in conjunction with drawings and Examples, this utility model is further described:
Fig. 1 is the cutaway view of this utility model embodiment.
Wherein: 1. top 11. bayonet socket 12. cervical region 13. bizet 2. bottom 21. trips.
The specific embodiment
Embodiment:
As shown in Figure 1,2 tops, bottom are provided with the trip 21 of a T font, and the below on top 1 offers the bayonet socket 11 of coupling, the section shape on top 1 is the T font, the sectional area of bizet 13 is greater than the sectional area of cervical region 12, and trip 21 is stuck in bayonet socket 11, then carries out the hot pressing connection.When rubber stopper is filled in medicinal liquid bottle, the foreign aid lower surface of bizet 13 contact bottleneck, the cervical region of the periphery wall of cervical region 12 and Pharmaceutical bottle fits tightly, and plays the effect of sealing.Bottom 2 can contact with medicinal liquid, use preferably material of the biological or chemical compatibility, and the common synthetic or natural rubber that price is lower is used on top 1 in order to reduce production costs.
Due to top 1 and the bottom 2 different material that uses, its contact surface can separate because the compatibility is different, the present embodiment has been set up trip 21 above bottom 2, and the bayonet socket 11 of coupling has been offered on top 1, in the physical bond power that has increased between top 1 and bottom 2, make it not easily separated each other.
Those skilled in the art will readily understand; the foregoing is only preferred embodiment of the present utility model; not in order to limit this utility model; all any modifications of doing within spirit of the present utility model and principle, be equal to and replace and improvement etc., within all should being included in protection domain of the present utility model.
Claims (3)
