Detailed description of the invention

As shown in Figures 1 to 6, one has anti-fraud functional bottle cap to this utility model, includes upper cover 10, lower cover 20 and False proof ring 30, wherein:

This upper cover 10 has Handheld Division 11 and is arranged at the connecting portion 12 of lower end, Handheld Division 11, and this connecting portion 12 has a spiral shell Pit 121, is arranged at intervals with a plurality of locating slot 122 in 121 mouthfuls of sidewall upper annular of this screwed hole, in 121 mouthfuls of roofs of screwed hole On be provided with annular seal plate 123.

This lower cover 20 upper end has a stud 21 matched with above-mentioned screwed hole 121, is spaced around this stud 21 root Be provided with a plurality of double wedge 22, this double wedge 22 towards catching up with lid 10 by (i.e. upper cover 10 side of unscrewing, direction screwed off on lower cover 20 To) contrary, and it is concavely provided with an embedding slot 211 matched with above-mentioned annular seal plate 123 in stud 21；In lower cover 20 lower end It is provided with the encapsulation part 23 coordinated with bottleneck to be packaged.

This false proof ring 30, in syllogic, is connected by fillet 31 between adjacent segment, and on every section of false proof ring inwall, interval is arranged Having two wallboards 32 the most gradually thickeied, wherein wallboard 32 top vertical in every section of false proof ring 30 is provided with location Block 33, is provided with a projection 34 in another wallboard 32 inner wall at end, and this locating piece 33 matches with above-mentioned locating slot 122, and three Locating piece 33 on section false proof ring 30 is spaced 120 degree, and false proof ring 30 upper wall block 32 lays respectively at fillet 31 both sides.

The stud 21 of this lower cover 20 is combined in the screwed hole 121 of upper cover 10, and annular seal plate 123 is positioned at embedding slot 211 In, the sealing of bottle cap can be improved, this false proof ring 30 is located between upper cover 10 and lower cover 20, and it is outside to be coated on double wedge 22, The locating piece 33 of false proof ring 30 is inserted in above-mentioned locating slot 122, and the wallboard 32 of false proof ring 30 contacts with double wedge 22.

Operation principle of the present utility model is as follows: when being backed out by bottleneck by bottle cap, necessarily causes upper cover 10 and lower cover 20 Between produce relative rotation, upper cover 10 by when screwing off on lower cover 20, lower cover 20 upper raised teeth 22 can gradually with the wall of false proof ring 30 Plate 32 contacts, relatively thin to thicker position by wallboard 32, when finally projection 34 contacts with double wedge 22 on wallboard 32, is positioned at two Fillet 31 between wallboard 32 will contact, by double wedge 22, the maximum tensile stress produced with protruding 34, thus forces fillet 31 disconnected Splitting, false proof ring 30 is broken into three sections, i.e. shows that upper cover 10 and lower cover 20 are relatively rotated, it is believed that bottle cap is previously opened, And, false proof ring 30 is disposable ring, it is impossible to restored.Therefore, antifalse effect is played.

Design focal point of the present utility model is, by false proof ring utilizes the cooperation of locating slot and locating piece be fixed on Between lid and lower cover, utilize relatively rotating between upper cover and lower cover, make lower cover upper raised teeth and the wallboard on false proof ring and projection Mutually sliding contact, makes fillet on false proof ring be ruptured by maximum tensile stress, and false proof ring is i.e. broken into three sections, and cannot Restore, thus, playing the antifalse effect of bottle cap, this anti-fake bottle lid simple in construction, easy to operate, antifalse effect is notable, has wide The wealthy market space.

The above, be only preferred embodiment of the present utility model, not make technical scope of the present utility model Any restriction, thus every according to technical spirit of the present utility model to any trickle amendment made for any of the above embodiments, equivalent become Change and modify, all still falling within the range of technical solutions of the utility model.
