Embodiment:

As shown in Figure 1 and Figure 2, the utility model anti-fake bottle lid is made up of enclosing cover 1, inner cap 2, bottleneck 3, interior plug 4 and following pipe 5, enclosing cover 1 and inner cap 2 are connected to an integral body by mutual close-fitting perpendicular tooth 6, and inner cap 2 is connected by double thread 7 with bottleneck 3 and is pressed together.The bottom of enclosing cover 1 is provided with and twists off ring 8, and this twists off ring and links to each other with enclosing cover 1 by a plurality of point of connection 16, twists off on the ring 8 and also is provided with at least one vertical opening 10, makes that twisting off ring 8 when outwarding winding enclosing cover disconnects and disengaging glass bottleneck 17 from vertical opening 10.In plug 4 top and the junction of bottleneck 3 be provided with annular projection 11, its underpart and the faying face place of glass bottleneck 17 and be provided with lip 15 on seal ring 12 and the inner cap 2 and cooperate with the region of interest of bottleneck 3 and all play sealing function.The upper surface and the bottleneck junction of inner cap 2 are provided with sealing lip circle 9 simultaneously, and interior plug 4 is provided with ring-like sealing band 13 with the junction, last plane of bottleneck 3, has played the effect of secondary seal, and sealing property is strengthened.In addition, the afterbody of following pipe 5 is made and is prevented from the thin-walled tube wall construction 14 that prizes to have improved anti-counterfeiting performance.
