Description

A kind of leakproof bottle cap

The utility model relates to a kind of bottle cap, particularly a kind of leakproof bottle cap.

At present, the bottle cap of selling and using on the market though adopt various false proof measures mostly, does not possess the function that anti-liquid leaks, in case the anti-counterfeit structure of bottle cap is destroyed, institute's holding liquid must use in the bottle, otherwise liquid easily spills or vulnerable to pollution in the bottle.

The purpose of this utility model will provide a kind of leakproof bottle cap exactly, and it not only has the antiforge function of conventional bottle cap, can also guarantee that under the situation that anti-counterfeit structure destroys, institute's holding liquid can not spill in the bottle, can prevent effectively that bottle interior institute holding liquid is not contaminated.

The purpose of this utility model is achieved in that a kind of leakproof bottle cap, comprise enclosing cover 1 and inner cap 3, inner cap 3 is fixedly connected with bottleneck 4, liquid is set on the inner cap 3 portals 8,8 the valve body 2 of can airtight described liquid portalling is connected with inner cap 3, enclosing cover 1 is connected with inner cap 3, and inner cap 3 and valve body 2 are positioned at the enclosing cover 1 of hollow.Pore 9 is set on the inner cap 3.Rotatable valve body 2 is enclosed within outside the inner cap 3, is provided with on it with described liquid to portal 8 and pore 9 corresponding through holes.Back-up ring 10 is connected with inner cap 3 ends, and valve body 2 is between back-up ring 10 and inner cap 3 bottoms.Valve body 2 is made up of button 11, pull back spring 12 and valve rod 13, and button 11 is connected with the valve rod 13 that can seal 3 mouthfuls of inner caps, is provided with pull back spring 12 between button 11 and the valve rod 13.Valve body 2 is made up of push button 5 and hanging body 6, is provided with elastic recoil circle 7 between push button 5 and the hanging body 6.

The utility model is owing to be provided with valve body structure interior covering, and valve body adopts and push away or change or by three kinds of structures with auto-lock function, so when need pouring out bottle interior an institute holding liquid, need push away or change or to press valve body promptly pourable by finger.When not needing bottle interior liquid to flow out, only need unclamp push away by or the finger of rotary valve body, valve body automatically resets by the elasticity self-locking mechanism, institute's holding liquid promptly is in sealed state in the bottle, can not polluted.Because enclosing cover that connects and have secondary seal with inner cap of bottleneck outer setting, in a single day so the sealing enclosing cover of outwarding winding, enclosing cover will break automatically again, can not repeated usage, have antiforge function.The utility model also has functions such as simple in structure, esy to use, safe and reliable.

Concrete structure of the present utility model is provided by following embodiment and accompanying drawing thereof.

Fig. 1 is the scheme drawing of a kind of structure of the utility model.

Fig. 2 is the scheme drawing of the another kind of structure of the utility model.

Fig. 3 is the scheme drawing of another structure of the utility model.

Wherein: Fig. 1 double as Figure of abstract.

Among the figure: 1, enclosing cover, 2, valve body, 3, inner cap, 4, bottleneck, 5, push button, 6, hanging body, 7, the elastic recoil circle, 8, liquid portals, 9, pore, 10, back-up ring, 11, button, 12, pull back spring, 13, valve rod.

Embodiment 1: see Fig. 1.

A kind of bottle cap of leakproof, form by enclosing cover 1, valve body 2 and inner cap 3, valve body 2 is by push button 5, hanging body 6 and elastic recoil circle 7 are formed, valve body 2 is arranged on the inner cap 2, the lower end of valve body 2 is provided with liquid and portals 8 and pore 9, and enclosing cover 1 sealing is positioned at outside inner cap 3 and the bottleneck 4, is provided with elastic recoil circle 7 between push button 5 and the block body 6.

During use, the enclosing cover 1 of outwarding winding, enclosing cover 1 promptly breaks, and uses finger push push button 5 then, and push button 5 drives valve bodies 2 reaches, and at this moment, atmosphere promptly communicates with pore 9 on the inner cap 3, and institute's holding liquid can portal from liquid and pours out 8 in the bottle.In the time of need not using, only need unclamp the finger that promotes push button 5, push button 5 from being about to push button 5 returns, so just makes bottle interior liquid be in the close situation of envelope under the elastic force effect of elastic recoil circle 6, topples over bottle in any case, and liquid all can't be poured out in the bottle.Can guarantee that like this a bottle interior liquid that can not spills, can avoid bottle interior liquid to be polluted again.

Embodiment 2: see Fig. 2

A kind of bottle cap of leakproof is made up of enclosing cover 1, valve body 2 and inner cap 3, and valve body 2 is arranged on the inner cap 3, and valve body 2 can rotate on inner cap 3, and valve body 2 tops are provided with back-up ring 10, and enclosing cover 1 sealing is positioned at outside inner cap 3 and the bottleneck 4, and the side of valve body 2 is provided with liquid and portals 8.During use, the enclosing cover 1 of outwarding winding, enclosing cover 1 promptly breaks, and rotates valve body 2 with hand then, and liquid can portal from liquid and 8 pours out in the bottle, because valve body 2 tops are provided with back-up ring 10, upwards screws out in rotation so can prevent valve body 2.In the time of need not using, only need unclamp the valve body 2 that rotates with hand, under the effect of valve body 2 self-locking mechanism in valve body 2, promptly from horizontal reset, liquid is in the close situation of envelope in the bottle like this, topples over bottle in any case, and liquid all can't be poured out in the bottle.Can guarantee that like this a bottle interior liquid that can not spills, can avoid bottle interior liquid to be polluted again.

Embodiment 3: see Fig. 3

A kind of bottle cap of leakproof, form by enclosing cover 1, valve body 2 and inner cap 3, valve body 2 is arranged on the inner cap 3, valve body 2 is made up of button 11, pull back spring 12 and valve rod 13, pull back spring 12 is positioned at 12 of button 11 and self-closing valve rods, enclosing cover 1 sealing is positioned at outside inner cap 3 and the bottleneck 4, and button 11 links to each other with valve rod 12, and valve body 2 sides are provided with liquid and portal 8.

During use, the enclosing cover 1 of outwarding winding, enclosing cover 1 promptly breaks, the knob down 11 that press...withes one's finger then, thus compressing pull back spring 12 drives valve rod 13 and moves downward, and at this moment institute's holding liquid promptly portals from liquid and 8 flows out in the bottle.In the time of need not using, only need unclamp and press the button 11 finger, button 11 drives valve rod 13 and automatically resets under the elastic force effect of pull back spring 12, at this moment just makes bottle interior liquid be in the close state of envelope, topples over bottle in any case, and bottle interior liquid all can't be poured out.Can guarantee that like this a bottle interior liquid that can not spills, can avoid bottle interior liquid to be polluted again.
