Fig. 3 is for partly cuing open structural representation behind the bottle cap complete opening shown in Figure 1.

The specific embodiment

Below in conjunction with the drawings and specific embodiments anti-fake bottle lid of the present utility model is described further.

As shown in Figure 1, be a kind of novel false proof bottle cap of the present utility model, comprise that tapped loam cake 1 and one are with externally threaded doffing 2, doffing 2 is in loam cake 1 below and is connected with loam cake 1 by screw thread.Loam cake 1 is connected and composed by epimere and hypomere, the negative thread of loam cake 1 is positioned within the epimere, simultaneously with reference to shown in Figure 2, linkage section 1D between epimere and the hypomere is connected for weak, promptly this place's Joint strenght is lower than other position, for example can connect, also can be the connection mode of other easy tear fracture for the point-like of circular groove or interruption as shown in Figure 2; The epimere lower edge is provided with the first groove 1A of annular.

Combine by mutual chimeric convex-concave structure between the hypomere of loam cake and the doffing 2, and the width of convex-concave structure further groove on bottle cap is axial is greater than the width of flange.For example adopt in the present embodiment inserting in the groove that between flange 2A and flange 2D, constitutes on the doffing 2 on the loam cake hypomere to projecting inward flange 1E, the width of convex-concave structure further groove is greater than the beneficial effect of the width of flange 1E: shown in seeing figures.1.and.2, when opening bottle cap, because the hypomere of loam cake 1 can be made (miles of relative movement of flange 1E in groove) longitudinal travel of rotation and certain distance with respect to doffing 2, therefore make when uncapping it is that the first groove 1A that metal is trapped on the epimere of upper limb and loam cake 1 of 4B separates, along with continuing longitudinal travel upwards, loam cake 1 make the second groove 1B on the hypomere of loam cake 1 also deviate from the trap constraint of 4B upper limb of metal, the epimere that just can make loam cake 1 then disconnects with hypomere and separates, with respect to separating simultaneously, reduced and opened the used external force of bottle cap.Therefore,, also can on the loam cake hypomere, form inside groove, and the flanged structure that embeds in this groove is set on doffing according to this principle.

Be with outside loam cake 1 and overlap 4A on the metal, can adopt soft metals such as aluminum or aluminum alloy or copper to make material, the lower edge of cover 4A embeds and terminates in the first groove 1A of loam cake epimere lower edge on the metal.Outside doffing 2, be with the metal 4B that traps, can adopt ductile metal such as aluminum or aluminum alloy or copper to make material equally, the trap upper limb of 4B of metal embeds equally and terminates in the first groove 1A of loam cake epimere lower edge, and metal is trapped and also is entrenched togather by convex-concave structure between 4B and the doffing 2, makes axial relative displacement to prevent the metal 4B that traps with respect to doffing 2.For example the flange 2D of outside protrusion is set by trapping on 2 in the present embodiment, groove 4B2 is set is embedded in flange 2D upper-lower position and on metal is trapped 4B, be positioned at the upper and lower position of flange 2D, so that both are entrenched togather at metal.

As shown in Figures 2 and 3, when bottle cap is outwarded winding, under the effect of screw thread hoisting force, make on the whole and metal of loam cake 1 cover 4A together upwards and doffing 2 generation relative displacemenies.Along with loam cake 1 continue move up, the groove 1A of loam cake 1 bottom deviates from the trap constraint of 4B upper limb of metal, the second groove 1B on the hypomere of loam cake 1 also deviates from the trap constraint of upper limb of metal in succession, stopped by the flange 2A of doffing 2 thereupon loam cake 1 hypomere that moves and can not continue to move up this moment, and the epimere of loam cake 1 and comprise that groove 1A continues to move up, cause loam cake 1 beginning to be ruptured, loam cake 1 hypomere is stayed in metal is trapped the upper limb of 4B along the weakest point of connection 1D place.Arrive this bottle cap complete opening.

As shown in Figures 2 and 3, behind the bottle cap complete opening, loam cake 1 hypomere is retained in metal and traps in the 4B, and the first groove 1B of loam cake 1 hypomere exposes and remaines in metal and traps outside the upper limb of 4B, and the hypomere that this moment, loam cake 1 the ruptured metal of can not withdrawing is trapped in the 4B also and can not be deviate from the metal 4B that traps between groove 4B1 that metal traps and the doffing flange 2A because of ending in.Because of the groove 1A of plastic material loam cake 1 bottom is downward exit skirt shape under the effect of material plasticity, in case the bottle cap complete opening, the groove 1A of loam cake 1 and its underpart can not insert metal again and traps in the 4B so, reaches false proof purpose.

Loam cake and inner core can adopt transparent plastics, and no matter metallic sheath 4A, 4B are the metal color of himself, still in order to decorate formed coloured coating, make that all overlapping the trap color of 4B of 4A, metal on loam cake 1 and the metal forms distinct contrast, after in case bottle cap is opened and is used, the customer is easy to identify, can not recycle and reuse.

As shown in Figure 1 to Figure 3, at described loam cake 1 hypomere upper limb the 3rd groove 1C can be set also, the described metal fluted 4B1 of 4B that traps embeds in the 3rd groove 1C of loam cake hypomere, and the 3rd groove 1C width in the axial direction is more than or equal to the metal width of 4B upper groove 4B1 to its upper limb of trapping on the loam cake hypomere, make the loam cake hypomere to do slide relative with respect to the metal 4B that traps, described doffing adopts plastic materials such as plastics equally.The constraint effect of 4B because metal is trapped like this to the loam cake hypomere, the epimere and the hypomere that can guarantee loam cake 1 disconnect from linkage section 1D easily, in addition, because plasticity as the plastic material of doffing 2, also make after opening fully, the second groove 1B of loam cake 1 bottom of having ruptured can be exposed to metal and trap outside the 4B, and can not withdraw in 4B because of the second groove 1B is downward bell mouth shape, and the 3rd groove 1C of loam cake 1 bottom stays in metal is trapped the upper limb of 4B.Behind the complete opening, make the customer be more prone to identification at bottle cap more like this, and groove 1A, the 1B of loam cake 1 and its underpart all can not insert metal again and trap in the 4B, reach better antifalse effect.

The formation loam cake in the present embodiment and the plastic material of doffing are meant that plastics etc. have certain plastic deformation ability and elastomeric material.
