Abstract
The invention provides a leakage-proof bottle cap, which comprises a cap surface and a circumferential wall downwards extending along the edge of the cap surface, wherein a long bulge which downwards extends and is sealed along the circumferential direction is concentrically arranged on the inner top surface of the cap surface, and a sealing part tightly abutted against and matched with the inner side edge of the upper end part of a bottle opening is arranged on the outer periphery of the upper end part of the long bulge. The leakage-proof bottle cap has the advantages that the sealing part tightly abutted against and matched with the inner side edge of the upper end part of the bottle opening is arranged on the outer periphery of the upper end part of the long bulge arranged in the existing bottle cap, so that the inner wall of the bottle opening and the upper end part of the long bulge are tightly abutted against and matched for forming sealing connection, the long bulge can be effectively prevented from generating offset when the bottle cap suffers the side surface impact, and the sealing performance of the bottle cap is ensured.
Description
Technical field
The present invention relates to a kind of bottle cap, especially relate to a kind of leakage-resisting bottle cap of anti-side impact.
Background technology
Along with bottle cap is more and more towards lightweight future development, the capping of bottle cap is more and more thinner, in use will go wrong.As shown in Figure 1, the leakage-resisting bottle cap of prior art comprises capping 1 and the perisporium along capping edge to downward-extension 2, the inner top surface of capping 1 is provided with one heart to downward-extension and the length convex 3 circumferentially closed.Lid is tightened in after on bottleneck 4, there is certain gap between the inside edge of the upper end of long convex upper end and bottleneck 4, as shown in Figure 2.Through contriver's test repeatedly, after bottle cap locking bottleneck 4, long convex 3 positions may be caused to offset, may cause gas leakage time serious when bottle cap meets with side impact, the phenomenon such as to leak, causes a hidden trouble safely to the beverage in bottle.
Summary of the invention
In order to overcome the defect of above-mentioned prior art, the object of this invention is to provide a kind of anti-side impact, the better leakage-resisting bottle cap of sealing effectiveness, after preventing bottle cap from meeting with side impact, long convex position offsets, and ensures the sealing property of bottle cap.
For achieving the above object, the present invention by the following technical solutions:
A kind of leakage-resisting bottle cap, comprise capping and along capping edge to the perisporium of downward-extension, the inner top surface of described capping is provided with one heart the length also circumferentially closed to downward-extension convex, it is characterized in that: the periphery of the upper end that described length is convex has and supports friction tight sealing with the inside edge of bottleneck upper end.
Preferably, described sealing is along the convex radially outward protruding and circumferentially closed step of described length.
More preferably, the height that described step is radially protruding diminishes from top to bottom gradually.
In one embodiment, described leakage-resisting bottle cap also comprise be arranged on described inner top surface and described perisporium and described length convex between seal ring, the upper end of bottleneck is pushed against between described seal ring and described sealing.
Compared to prior art, the present invention improves long male structure on the basis of existing technology, arrange in the periphery of long convex upper end and support friction tight sealing with the inside edge of the upper end of bottleneck, allow the inwall of bottleneck 4 and long convex 3 upper end push against and coordinate and formed and be tightly connected, affect the weight of bottle cap so hardly, side impact duration is convex to be offset effectively to prevent again bottle cap from suffering, and ensure that the sealing property of bottle cap.

Detailed description of the invention
Below in conjunction with accompanying drawing, the preferred embodiment of the present invention is described in detail.
Refer to Fig. 3 and Fig. 4, it illustrates leakage-resisting bottle cap of the present invention, it comprises capping 1 and along capping 1 edge to the perisporium 2 of downward-extension, the inner top surface of capping 1 is provided with one heart to downward-extension and the length convex 3 circumferentially closed, the periphery of the upper end of length convex 3 has and supports friction tight sealing 31 with the inside edge of bottleneck 4 upper end.The leakage-resisting bottle cap of the present embodiment also comprise be arranged on capping 1 inner top surface on and seal ring 11 between perisporium 2 and long convex 3, the upper end of bottleneck 4 is pushed against between seal ring 11 and sealing 31.The bottom of perisporium 2 has integrated anti-theft ring 22 and blade ring 23.
In the present embodiment, sealing 31 is the radially outward protruding of edge long convex 3 and step that is that circumferentially close, and this step is formed in one between the upper end and the inner top surface of capping 1 of length convex 3.In order to make the step 31 of long convex 3 enter bottleneck 4 smoothly, the radially protruding height of this step diminishes from top to bottom gradually.Bottle cap is screwed in the process of bottleneck 4, the bottom of long convex 3 is introduced in bottleneck 4, then the lower end of step contacts with the inside edge of the upper end of bottleneck 4, continue to tighten in the process of bottle cap, pressure between the long step of convex 3 and the inside edge of the upper end of bottleneck 4 increases gradually, until after tightening completely, the long step of convex 3 and the inside edge of bottleneck 4 seal tightly and are combined together.
Mating reaction is pushed against due to sealing 31 and bottleneck 4, when bottle cap meets with side impact, the position of long convex 31 also can not offset, and the inside edge of bottleneck 4 upper end is tightly connected all the time with the sealing 31 of long convex 3, guarantee the sealing property of bottle cap, avoid gas leakage, leak.Therefore, the present invention is on existing bottle cap basis, adopt the minimum structural development of bottle cap weight, achieve the sealing property of excellent anti-side impact, easily leak gas after efficiently solving prior art long-standing bottle cap experience side impact, leak water problem.
Above-described embodiment is only for illustrating technical conceive of the present invention and feature; its object is to person skilled in the art can be understood content of the present invention and implement according to this; can not limit the scope of the invention with this; all equivalences done according to Spirit Essence of the present invention change or modify, and all should be encompassed within protection scope of the present invention.
