Summary of the invention
The purpose of this invention is to provide the bottle cap that a kind of effectively leakproof also can be applicable to the bottleneck of different patterns.
For solving the problems of the technologies described above, the present invention adopts following technical scheme:
A kind of bottle cap, comprise caping and the perisporium that arranges from the circumferential edge of described caping to downward-extension, described perisporium has the connecting portion that is connected with bottleneck, be provided with one heart the leak-stopping blade ring of the circumferential sealing of extending in the same way with described perisporium on the described caping, the periphery wall of this blade ring and the inwall of bottleneck offset, between described blade ring and described perisporium, be provided with a seal ring that circumferentially seals on the described caping, described seal ring has internal face, and when this bottle cap was installed on the bottleneck: the oral area of described bottleneck was pushed against between described seal ring and the described blade ring.
Preferably, the internal face of described seal ring comprises the first conical surface section and the second conical surface section, along in the cross section straight down of the radius of described caping: the angle that described the first conical surface section is outwards opened from the inner bottom surface of described caping is α, the angle that described the second conical surface section is outwards opened from the inner bottom surface of described caping is β, and: 90 °＜β＜α＜180 °.
Preferably, the shape in the oral area of the shape of the internal face of described seal ring and the described bottleneck outside is suitable.
Preferably, the periphery wall of described blade ring is provided with at least one circle and is used for the bulge loop that offsets with the bottleneck inwall.
Preferably, the bottom of described perisporium is provided with anti-theft ring, has several dowels between the bottom of described anti-theft ring and described perisporium.
Preferably, the outside wall surface of described perisporium is provided with some the fins of being convenient to grasp that distribute vertically that are parallel to each other.
The invention has the beneficial effects as follows: seal ring is designed to the first conical surface section and the second conical surface section, the first conical surface section is connected to the inner bottom surface of caping, angle between the first conical surface section and the bottle cap inner bottom surface is greater than 90 °, so that capping can bear larger sealing pressure, can not cause expect the rough phenomenon of capping after the bottle cap sealing, be of value to the carrying out of the operation of follow-up silk-screen, and, the design of the second conical surface section can adapt to the bottleneck of different patterns, strengthens its sealing property.

In the accompanying drawing: 1, caping; 2, perisporium; 3, blade ring; 4, seal ring; 5, the first conical surface section; 6, the second conical surface section.
The specific embodiment
Below in conjunction with embodiment shown in the drawings technical scheme of the present invention is done following detailed description the in detail:
Such as accompanying drawing 1, accompanying drawing 2, shown in accompanying drawing 3 and the accompanying drawing 4, one embodiment of the present invention: this bottle cap comprises caping 1 and the perisporium 2 that extends to form along the circumferential edge of caping 1 downwards, the inwall of perisporium 2 has for the negative thread that is threaded mutually with bottleneck, the bottom of perisporium 2 is provided with anti-theft ring, have several dowels between this anti-theft ring and the perisporium 2, the outside wall surface of perisporium 2 is provided with some the axially extended fins of being convenient to grasp that are parallel to each other, be provided with one heart a leak-stopping blade ring 3 that circumferentially seals on the caping 1, the lower end of the outside wall surface of this blade ring 3 is provided with the bulge loop that at least one circle and bottleneck inwall offset, between the perisporium 2 on caping 1 inner bottom surface and blade ring 3, be provided with a side pressure seal ring 4, when bottle cap was installed in mouth cylindrical part: the bottleneck oral area was pushed against between blade ring 3 and the seal ring 4, this seal ring 4 has internal face, the outside of this internal face and bottleneck offsets, this internal face comprises the first conical surface section 5 and the second conical surface section 6, along in the radius cross section straight down of caping 1: the angle that the first conical surface section 5 is outwards opened from the inner bottom surface of caping 1 is α, the angle that the second conical surface section 6 is outwards opened from the inner bottom surface of caping 1 is β, and: 90 °＜β＜α＜180 °.
Above-mentioned α and the occurrence of β will be selected according to the model of bottleneck, and particularly, for example for the bottleneck of 1881-HF type or 1881-CAF type, α is 110 °, and β is 98 °.
