Abstract
The utility model discloses an aseptic powder butyl rubber stopper, including stopper crown and the stopper neck that lies in stopper crown lower extreme, stopper neck be the tube -shape, and the stopper neck is formed by connecting with frustum section of thick bamboo portion in straight section of thick bamboo portion, and straight section of thick bamboo position is in between stopper crown and the frustum section of thick bamboo portion, and the periphery bottom of frustum section of thick bamboo portion is provided with first bulge loop, and the surface of first bulge loop is including the last anchor ring and the lower anchor ring that are connected, and upward the outer fringe of anchor ring is higher than the inner edge, and lower anchor ring is connected with the bottom surface of filling in the neck, and the external profile diameter of first bulge loop equals or omit to be greater than a straight section of thick bamboo bottom surface diameter. This aseptic powder butyl rubber stopper simple structure, the external profile diameter equals or omit the first bulge loop that is greater than straight section of thick bamboo portion bottom surface diameter through setting up at stopper neck low side, through increasing the tight fit area between plug and the bottleneck, increases stiction between the two, reduces jump stopper phenomenon.
Description
Technical field
This utility model relates to medical rubber stopper, is specifically related to a kind of aseptic powder body butyl rubber plug.
Background technology
The pouring process of medical aseptic powder body injection is, subpackage mixed powder in the injection bottle after cleaning-drying cools down, and the butyl rubber plug after then cleaning is placed in bottleneck, after lid process is rolled in tamponade, enters test package operation.Being divided on injectable powder racking machine of mixed powder completes.The shape of aseptic powder body plug generally comprises plug bizet and plug cervical region, and plug cervical region, for close fit tight-lipped with powder injection bottle, finds in actual production process, when some plug is carried out tamponade process, owing to pressure of the inside of a bottle is excessive, it may appear that plug jumping phenomenon, it is unfavorable for that streamline operates continuously.Therefore, it is necessary to plug structure of the prior art is improved.
Utility model content
The purpose of this utility model is to overcome defect present in prior art, it is provided that the aseptic powder body butyl rubber plug that a kind of Assembly stability is good.
For realizing above-mentioned technique effect, the technical solution of the utility model is: a kind of aseptic powder body butyl rubber plug, it is characterized in that, including plug bizet and the plug cervical region being positioned at plug bizet lower end, described plug cervical region is tubular, described plug cervical region is formed by connecting by vertical tube part and frustum drum portion, vertical tube part is between plug bizet and frustum drum portion, the bottom, periphery in described frustum drum portion is provided with the first bulge loop, the outer surface of the first bulge loop includes the upper ring surface that is connected and lower anchor ring, the outer rim of upper ring surface is higher than edge, lower anchor ring is connected with the bottom surface of plug cervical region, the external profile diameter of described first bulge loop is equal or slightly larger than vertical tube part basal diameter.
In order to optimize the Assembly stability of plug, preferred technical scheme is, the cross section of described first bulge loop is triangle.The upper ring surface of the first bulge loop and lower anchor ring cross section are linear type, and the handing-over ring of upper ring surface and lower anchor ring can increase the stiction between plug and bottleneck with tight fit between bottleneck.
In order to optimize the Assembly stability of plug, preferred technical scheme is, the cross section of described lower anchor ring is the arc protruding to plug cervical region periphery, rounding off between bottom surface and the lower anchor ring of described plug cervical region.Lower anchor ring and plug cervical region bottom surface rounding off, can play guide effect when plug low side fills in bottleneck.
In order to optimize the Assembly stability of plug, preferred technical scheme is, the cross section of described upper ring surface and lower anchor ring is the arc protruding to plug cervical region periphery.When the external profile diameter of the first bulge loop is slightly larger than vertical tube part basal diameter, upper ring surface is to plug neck surface bending deformation, the lower anchor ring of the first bulge loop and bottleneck tight fit, contact area between the two is bigger, and due to bulge loop to bottleneck apply recover deformation active force, therefore can with coordinate between bottleneck tightr.
In order to increase the stiction between plug cervical region and bottleneck further, preferred technical scheme is, it is characterised in that the outer surface of described vertical tube part is in being vertically disposed with at least one of which the second bulge loop.
Advantage of the present utility model and having the beneficial effects that:
This aseptic powder body butyl rubber plug simple in construction, it is equal or slightly larger than the first bulge loop of vertical tube part basal diameter by arranging external profile diameter at plug cervical region low side, by increasing the tight fit area between plug and bottleneck, increase stiction between the two, reduce plug jumping phenomenon.

Detailed description of the invention
Below in conjunction with the accompanying drawings and embodiment, detailed description of the invention of the present utility model is further described.Following example are only used for clearly illustrating the technical solution of the utility model, and can not limit protection domain of the present utility model with this.
Embodiment 1
As depicted in figs. 1 and 2, the aseptic powder body butyl rubber plug of embodiment 1, including plug bizet 1 and the plug cervical region 2 being positioned at plug bizet 1 lower end, plug cervical region 2 is tubular, plug cervical region 2 is formed by connecting by vertical tube part 21 and frustum drum portion 11, vertical tube part 21 is between plug bizet 1 and frustum drum portion 22, the bottom, periphery in frustum drum portion 22 is provided with the first bulge loop 3, the outer surface of the first bulge loop 3 includes the upper ring surface 31 that is connected and lower anchor ring 32, the outer rim of upper ring surface 32 is higher than edge, lower anchor ring 32 is connected with the bottom surface of plug cervical region 2, the external profile diameter of the first bulge loop 3 is slightly larger than vertical tube part 21 basal diameter.
The outer surface of vertical tube part 21 is in being vertically disposed with one layer of second bulge loop 4.
The cross section of the first bulge loop 3 is triangle.
Embodiment 2
As shown in Figure 3 and Figure 4, embodiment 2 is distinguished as with embodiment 1: the cross section of lower anchor ring 32 is the arc protruding to plug cervical region 2 periphery, rounding off between bottom surface and the lower anchor ring of plug cervical region 2.
The outer surface of vertical tube part 21 is in being vertically disposed with two-layer the second bulge loop 4.
Embodiment 3
As shown in Figure 5 and Figure 6, the cross section of upper ring surface 31 and lower anchor ring 32 is the arc protruding to plug cervical region 2 periphery.
In embodiment 1, the external profile diameter of the first bulge loop also can be equal to vertical tube part basal diameter, and compared with embodiment, external profile diameter is more preferable slightly larger than the plug-bouncing effect of vertical tube part basal diameter.
The above is only preferred implementation of the present utility model; should be understood that; for those skilled in the art; on the premise of without departing from this utility model know-why; can also make some improvements and modifications, these improvements and modifications also should be regarded as protection domain of the present utility model.
