Abstract
The utility model provides an ejection-proof butyl rubber bottle plug, which mainly comprises a bottle plug cover and a bottle plug neck. The bottle plug neck is fitted with the bottle mouth through an arch face, and the peak of the arch face is arranged in the lower middle part of the whole fitting face. The bottle plug cover and the bottle plug neck are one-time formed, a bottle plug cavity is arranged inside the bottle plug neck for material saving, and the cavity may be designed into a semi sphere or other shapes. The beneficial effect of the utility model is that the fitting face of the rubber plug neck is changed into an arch face, and the peak of the arch face is arranged in the lower middle part of the whole fitting face. Such design enables the rubber plug to be pressed into the bottle mouth more easily in comparison with traditional cylinder or conical plug. On the other hand, when the rubber plug neck is pressed into the bottle mouth, the elasticity of the rubber plug will produce a friction force between the peak of the neck arch and the bottle mouth to resist ejection of the rubber plug, thus solving the problem of ejection of the rubber plug from the bottle mouth.
Description
Technical field
The utility model relates to the butyl rubber medicinal bottle stopper, mainly relates to a kind of anti-jump butyl rubber bottle stopper.
Background technology
Medicinal rubber bottle stopper uses the butyl rubber butyl rubber to have excellent air-tightness, good chemical inertness and biologically inert abroad already as a kind of leakproofing material of direct contact medicine and is widely used in medical leakproofing material; China is because historical reasons is used natural rubber always.For promoting the civilian medicine safety of Chinese people, the Chinese government progressively eliminates the natural rubber bottle stopper since the early 1990s in last century and uses butyl rubber bottle stopper instead.
In order to guarantee sealing effectiveness, butyl rubber plug and medicinal glass bottle generally adopt interference fit, and promptly the mating part size recess diameter of plug is greater than glass bottle bottleneck internal diameter, and for ease of plug is compressed into glass bottle opening, the plug neck is the post taper.Because plug is a kind of elastomeric material, plug just might overcome friction and the bottleneck that jumps out promptly produces jumping and fills in like this.In fact jumping plug has been the subject matter that the puzzlement plug uses on the machine the aspect.
Summary of the invention
The utility model will solve above-mentioned existing shortcoming, and a kind of anti-jump butyl rubber bottle stopper is provided.
The utility model solves the technical scheme that its technical matters adopts: this anti-jump butyl rubber bottle stopper, mainly constitute by bottle stopper and neck of bottle stopper, described neck of bottle stopper be arc surface with fitting surface bottleneck, the highest point of arc surface is arranged on the middle and lower part of whole fitting surface.
Bottle stopper described in the utility model and neck of bottle stopper are one-body molded, and for saving in material is provided with the bottle stopper inner chamber, the bottle stopper inner chamber can be designed to spherical or other shapes of semicircle in the neck of bottle stopper.
The effect that the utility model is useful is: according to medicine leak free actual needs, the actual features of using in conjunction with plug, the anti-jump butyl rubber bottle stopper of my company's design-calculated, change plug neck fitting surface into arc surface, and the highest point of arc surface is placed on the middle and lower part, the plug that excessively makes of circular arc is more convenient for being pressed into the more traditional post taper of bottleneck so on the one hand, on the other hand, after the plug neck is pressed into bottleneck, the elasticity of plug can be impelled and form a kind of friction force that plug jumps out of resisting between the highest point of neck circular arc and the bottleneck, effectively solves the problem that plug is jumped out from bottleneck.
Description of drawings
Fig. 1 is a main TV structure scheme drawing of the present utility model;
Fig. 2 is a plan structure scheme drawing of the present utility model;
Reference numeral: bottle stopper 1, neck of bottle stopper 2, fitting surface 2-1, bottle stopper inner chamber 3.
The specific embodiment
Below in conjunction with drawings and Examples the utility model is described in further detail.
As Fig. 1-shown in Figure 2, this anti-jump butyl rubber bottle stopper, mainly constitute by bottle stopper 1 and neck of bottle stopper 2 are one-body molded, the fitting surface 2-1 of neck of bottle stopper 2 is arc surface, the highest point of arc surface is arranged on the middle and lower part of whole fitting surface, and promptly the maximum gauge of arc surface is arranged on the middle and lower part of whole fitting surface.The transition of circular arc makes the more traditional post taper of plug be more convenient for being pressed into bottleneck so on the one hand, on the other hand, after neck of bottle stopper 2 is pressed into bottleneck, the elasticity of plug can be impelled and form a kind of friction force that plug jumps out of resisting between the highest point of neck circular arc and the bottleneck, effectively solves the problem that plug is jumped out from bottleneck.In addition, for saving in material is provided with bottle stopper inner chamber 3, bottle stopper inner chamber 3 can be designed to spherical or other shapes of semicircle in the neck of bottle stopper 1.
