The pad set-up mode of another improvement, as shown in Figure 2, the medial surface of this bottle cap 5 is provided with one and is bending, and rubber-like leakproof ring 51, after bottle 1 borrows the negative thread 52 of outside thread 12 and bottle cap 5 to screw the location, the center section part 511 of the top bottleneck 11 proper protruding top bending leakproof rings 51 of this bottle 1, make its center section part 511 and bottle cap 5 inner top surfaces form a suitable spacing, so when bottle 1 and bottle cap 5 screw the location, borrow bottleneck 11 that leakproof ring 51 is compressed to bottle cap 5 inner top surface directions, make bottleneck 11 and leakproof ring 51 center section parts 511 make a sealing contact, though only this mode can borrow 511 actions of bottleneck 11 roof pressure leakproof rings 51 center section parts to reach the anti-effect of letting out in bottle cap 5 sealed uses, but, because of its leakproof ring 51 is that a ring body that is to tilt bending designs, when leakproof ring 51 center section parts 511 when continuing to be compressed, the turnover extension 512 of these leakproof ring 51 center section parts 511 is promptly because of the pressurized in stage casing 511, and make it upwards promote outer sticking up, this turnover extension 512 also can't be pasted with bottleneck 11 inner faces, repeatedly constantly heavily cover unlatching again, the condition of service of sealed bottle cap 5, then cause the elastic fatigue of leakproof ring 51 turnover extensions 512, when bottle cap 5 being locked together in bottle 1 top fully as the user end, this bottleneck 11 promptly can't roof pressure bottle cap 5 leakproof ring 51 center section parts 511, and under the situation of turnover extension 512 elastic fatigues, this bottle cap 5 promptly can't reach the effect that prevents bottle interior fluid seepage, and loses original design-calculated leakproof application target.

In view of this, the purpose of this utility model provides a kind of later-model leakproof bottle cap, and the flange that can effectively prolong bottle cap moves to the anti-stroke of letting out that breaks away from the bottleneck opening part, strengthens bottle cap and is revolving the antiseepage utilization benefit of putting sealed bottle body and bottleneck place.

The purpose of this utility model is achieved in that a kind of novel anti-leakage bottle cap comprises the thread segment that the bottle cap internal diameter is offered, and is characterized in that: be provided with ring seat and extend folding part outside at the bottle cap inner top surface, this outer folding part end has a flange.

The peripheral interval of above-mentioned ring seat is provided with a baffle ring.

Owing to adopt such scheme: can prevent that bottle interior liquid is from the bottle cap seepage.
