The specific embodiment

Below in conjunction with accompanying drawing and preferred embodiment the utility model is described in more detail.

Seal bottle cap according to a kind of preferred embodiment of the present utility model comprises the lid base 2 shown in the lid 1 shown in Fig. 1 and Fig. 2, and wherein, lid base 2 matches with the bottleneck 3 shown in Fig. 3.

As shown in fig. 1, lid 1 comprises ring wall 11 and sealing surface 12, and wherein, ring wall 11 inwalls have screw thread, can with the lid basic 2 screws thread fit.Also be provided with in the inboard of sealing surface 12 with respect to sealing surface 12 projectioies closed-loop 13.In addition, on the outer wall of ring wall 11, have perpendicular row striped, be used to increase the friction force of turning on lid 1.This lid 1 is for being made into integration.

As shown in Figure 2, the top of lid base 2 is connected with lid 1.The top of lid base 2 is provided with ring wall 25, and ring wall 25 outer walls are provided with screw thread on this, cooperates with the screw thread formation of ring wall 11 inwalls of lid 1.

Bottom at lid base 2 has external annulus 21 that is positioned at the outside and the internal ring wall 22 that is positioned at external annulus 21 inboards, wherein, has

bulge loop

211 and 221 respectively at the inwall of external annulus 21 ends and the outer wall of internal ring wall 22 ends.External annulus 21 and internal ring wall 22 are used to clamp bottleneck shown in Figure 33, and

bulge loop

211 and 221 can block the annular protrusion 31 on the bottleneck 3 just.

Preferably, as shown in Figure 2, bulge loop 211 outsides of being located at external annulus 21 ends are the convergent shape, the inboard is a platform, form hook-shapedly, this is because will cover base 2 when being installed on bottleneck 3, and the gradual change shape in the outside is convenient to will to cover basic 2 with pressure and directly is pressed into bottleneck 3, inboard flat-bed setting makes that then lid base 2 is not easy to break away from from bottleneck 3, adds undesirable substance afterwards in order to avoid the person of harboring evil designs pulls up whole lid base 2 and lid 1 in bottle.The platform of bulge loop 211 inboards shown in Figure 2 is just blocked by the platform of the annular protrusion shown in Fig. 3 31, thereby can not be directly lid base 2 be pulled up from bottleneck 3.
