Specific embodiment

The utility model is further described with the following Examples.

The Bottle cap structure of the present embodiment includes bottleneck（It is not shown）And bottle cap.With reference to Fig. 1, Fig. 2, bottle cap is in cylindrical shape, It is internal with cavity.The madial wall of bottle cap is not provided with screw thread, but smooth anchor ring.The foot of bottle cap is provided with four separation and splits Seam 2（With reference to Fig. 3, Fig. 4）.Separate crack 2 to be rectangle, the centerline axis parallel of its length direction and bottle cap.

With reference to Fig. 1, Fig. 2, it is one group that each two separates crack 2, with two bottle cap foot shapes separated between crack 2 of group Into a snap arm 1, the radial thickness of snap arm 1 is a, a=2mm（See Fig. 4）.Bottleneck has the ring-type draw-in groove around bottleneck lateral wall （It is not shown）.The end of snap arm 1 has the grab 13 for extending inwardly, and grab 13 has the locking surface 14 for blocking ring-type draw-in groove, Locking surface 14 is b, b=80 ° with the angle of bottle cap central axis.The end of snap arm 1 has the unlatching chamfering 15 for breaking snap arm 1 into two with one's hands.

With reference to Fig. 1, Fig. 3, the roof on the inside of bottle cap has two seal ring pieces 4 being coaxially disposed, the edge of bottleneck（Figure is not Show）Being placed between two seal ring pieces 4 can make bottleneck form liquid-tight envelope with bottle cap.

The Bottle cap structure of the present embodiment includes reinforcing ring 3, and reinforcing ring 3 is set in bottle cap lateral wall.The inner side of reinforcing ring 3 has Protuberance 31（See Fig. 2）, the outside of snap arm 1 is provided with pit 12 corresponding with the shape of protuberance 31.The outside of snap arm 1 is additionally provided with slippage slot 11, slippage slot 11 aligns with pit 12 on the circumferencial direction of bottle cap.Protuberance 31 can coordinate with slippage slot 11, realize reinforcing ring 3 are slidably connected with bottle cap.

The occupation mode of the Bottle cap structure of the present embodiment is as follows：

When closed closure is needed, only bottle cap need to be directly sleeved on bottleneck, then press bottle cap to its grab 13 and block bottle The ring-type draw-in groove of mouth, can make bottle cap close at bottle mouth position.Now, the edge of bottleneck can be inserted between two seal ring pieces 4, Two seal ring pieces 4 tightly clamp the edge of bottleneck, bottleneck is formed liquid-tight envelope with bottle cap.Then, reinforcing ring 3 is pushed to Its protuberance 31 enters the pit 12 of snap arm 1 from slippage slot 11（As shown in Figure 1）, reinforcing ring 3 is fixed with respect to bottle cap.Reinforcing Under the fixation of ring 3, grab 13 effectively blocks the ring-type draw-in groove of bottleneck；

When open bottle cover is needed, reinforcing ring 3 is first pushed to its protuberance 31 and enters to sliding from pit 12 by operator Groove 11.Then, can be inserted with finger tip and open chamfering 15, then outwards break the end of snap arm 1 into two with one's hands, make grab 13 and ring-type draw-in groove Depart from, you can bottle cap is taken out from bottleneck.

Alternatively, bottleneck lateral wall can be set the snap ring around bottleneck to substitute the ring-type draw-in groove, together Sample ground, the locking surface 14 of grab 13 can block the snap ring.

Finally it should be noted that above example is only used to illustrate the technical solution of the utility model, rather than to this reality With the limitation of novel protected scope, although being explained to the utility model with reference to preferred embodiment, this area it is general It is logical it will be appreciated by the skilled person that can be modified to the technical scheme of utility model or equivalent, without deviating from this reality With the spirit and scope of new technique scheme.
