The purpose of this utility model is achieved by the following technical solution: design a kind of anti-fake bottle lid, comprise top flat, overcoat, screw collar and Nei Sai, above filling in described top flat is arranged on, plug is matched with the endoporus of bottleneck in described, described overcoat is socketed on the outside face of screw collar tightly, the negative thread of described screw collar is meshed with the outside thread of bottleneck, it is characterized in that, lower end and bottleneck corresponding with it position at screw collar are provided with the structure of only permitting the screw collar unidirectional rotation, be provided with a packing ring between the top of the baffle ring on overcoat top and screw collar, described packing ring is connected with the periphery of top flat by some thin muscle.The structure of described permission screw collar unidirectional rotation is: be provided with some arc flexure strips in the bottom of screw collar, leave the gap between the cylindrical of flexure strip and the endoporus of overcoat, on flexure strip, be shaped on latch, on bottleneck, be provided with several unidirectional latches suitable with it.The structure of described permission screw collar unidirectional rotation can also be: be provided with the plurality of elastic sheet on the inwall of the bottom of screw collar, be provided with several unidirectional latches suitable with it on bottleneck.The lower end of cock body of plug is connected to a upwards arched arc inner bag in described, and the outside face of arch inner bag and the inside face of cock body form an interlayer, is provided with two the semicircle draw rings that can upwards turn up in the outside of the another port of cock body.

Aforesaid anti-fake bottle lid when rotating jacket, rotates simultaneously with its screw collar that tightly is nested together and moves down, and because of top flat is resisted against on the bottleneck, top flat can not move down; Being arranged on the packing ring of screw collar top between the overcoat baffle ring will move down with screw collar, will break the thin muscle that connects top flat and packing ring in the process of moving down, thereby destroy anti-counterfeit structure; This moment, top flat came off, and plug is the liquid in the pourable bottle in pulling out; Open simple and convenient, when screw collar be rotated move down after, be subjected to placing restrictions on of unidirectional rotation structure, can not reverse and get back to original position, avoided reclaiming the generation of fraud situation, the utility model is the better anti-fake bottle lid of a kind of anti-counterfeiting performance.

Further specify the utility model below in conjunction with drawings and Examples.In the accompanying drawing:

Fig. 1 is the structural representation of anti-fake bottle lid described in the utility model;

Fig. 2 is the mesh schematic representation of unidirectional rotation structure among Fig. 1;

Fig. 3 is the structural representation that the screw collar in the anti-fake bottle lid adopts another kind of unidirectional rotation structure;

Fig. 4 is the mesh schematic representation that adopts another kind of unidirectional rotation structure among Fig. 3;

Fig. 5 is an anti-fake bottle lid opening scheme drawing described in the utility model.

With reference to accompanying drawing, anti-fake bottle lid comprises top flat 1, interior plug 4, screw collar 3 and overcoat 2; The cock body 4-1 of interior plug 4 and the endoporus of bottleneck 5 closely cooperate, and seal.The endoporus of the cylindrical of screw collar 3 and overcoat 2 closely cooperates (can not relatively move), and the outside thread on the endoporus of screw collar 3 is provided with negative thread 3-1 and is arranged on bottleneck 4 cylindricals is meshed.Be provided with the unidirectional rotation structure of only permitting screw collar 3 unidirectional rotation in the lower end of screw collar 3 with corresponding bottleneck position, lower end; This structure that can only unidirectional rotation can be, is provided with some arc flexure strip 3-2 in the bottom of screw collar 3, and its end is provided with unidirectional latch 3-3, is provided with the suitable unidirectional latch 5-1 of described latch 3-2 to be meshed with it on the corresponding position of bottleneck.The hole inwall of the cylindrical of described flexure strip 3-2 and overcoat 2 leaves gap A, and flexure strip 3-2 can radially be magnified.The addendum face part of latch 3-3 becomes a sharp angle with tangent to periphery, and another part is vertical with tangent line, and described latch 5-1 becomes the vertical slot shape, its tooth root part becomes a sharp angle with tangent to periphery, and another part is vertical with tangent line, and the vertical surface of the two matches, play the spline effect, as shown in Figure 2.

As a kind of improvement of the present utility model, this structure that can only unidirectional rotation can also be:: be provided with some Elastic Teeth 3-4 that are a circumferential arrangement on screw collar 3 inwalls, its root is connected in the inwall of screw collar 3, end and tangent to periphery have angle, the end is embedded among the latch 5-1 of bottleneck, be similar to a kind of ratchet and pawl arrangement, the latch groove root part of bottleneck 5 becomes a sharp angle with tangent to periphery, and another part is vertical with tangent line.This vertical surface has limited the end of Elastic Teeth, has played the effect of unidirectional spline.See Fig. 4, during backward rotation, Elastic Teeth 3-2 elastic deformation slips over (not spline) from the latch groove inclined-plane on the bottleneck.

Top flat 1 is contained in the top of bottleneck 5, between the baffle ring of the top of screw collar 3 and overcoat 2 ends, be provided with a packing ring 1-1, and be connected with the periphery of top flat 1 with some thin muscle 1-2, this moment, top flat 1 can not take away under the described effect that is held packing ring, when being subjected to external force, thin muscle 1-2 can rupture.The negative thread 3-1 of screw collar 3 and the outside thread of bottleneck can be made minus thread.When the user rotarily opened bottle cap by the custom direction, overcoat 2 moved down with screw collar 3 rotations.The bore area that is connected with its outside face of arch inner bag 4-2 and cock body 4-1 at the cock body 4-2 of interior plug 4 in the lower end constitutes an interlayer B, increased the elasticity of interior plug 4, make its scale error and shape error that more can adapt to bottleneck 5, improve sealing property, prevent seepage.Being provided with two for ease of plug 4 edges at its other end in taking out has semi-round draw ring 4-3, can upwards turn up so that open the bottle cap person and upwards lift.Overcoat 2 can play the anti-burning effect of pick-proof with material such as metals.

During use, as long as hold overcoat 2, by the left hand direction rotation of custom, overcoat 2 can rotate descending with screw collar 3, at this moment, the upper surface of the bottleneck 5 top top flat 1 that can make progress makes the thin muscle 1-2 fracture of top flat 1, top flat 1 comes off, stretch out bottleneck 5 upper ends, at this moment, and the semicircle drop handle 4-3 of plug 4 in carrying, plug 4 gets final product pouring in upwards extracting.Plug 4 is still filled in tightly in bottleneck in during rotation, does not have thing and falls in the bottle.

Because unidirectional spline structure restriction screw collar 3 can only be left-handed and be moved down, can not and move up to reversing sense dextrorotation, thereby lid can not reset after screwing off, also just can not take off, it is broken by the top to add top piece 1, has played and has opened the anti-fake effect that identifies obviously and can not restore usefulness again.
