Specifically, the grab has locking surface, and locking surface is b, 75 °≤b≤85 ° with the angle of bottle cap axial direction.

Specifically, the snap arm end has the unlatching chamfering for prizing snap arm.

Specifically, the roof on the inside of bottle cap has two seal ring pieces being coaxially disposed, and the edge of the bottleneck is placed in two Bottleneck can be made to form liquid-tight envelope with bottle cap between individual seal ring piece.

Specifically, the separation crack is rectangle, and its length direction is axially in parallel with bottle cap.

Compared with prior art, the beneficial effects of the utility model are：

The drinking water bottle cap structure that the utility model is provided, including bottleneck and bottle cap, closure inside have cavity, bottle cap Cross section be round rectangle, the madial wall of bottle cap is smooth surface, and the foot of bottle cap is provided with four separation cracks, each two point It is one group from crack, a snap arm is formed with two bottle cap foots separated between crack of group, snap arm is located at the two of relative angle At individual fillet, snap arm end has towards projecting inward grab, and the bottleneck has draw-in groove corresponding with the grab shape.When need When wanting closed closure, only bottle cap need to be directly sleeved on bottleneck, then press bottle cap and the draw-in groove of bottleneck is blocked to its grab, can be by Bottle cap closes at bottle mouth position.Compared to prior art, drinking water bottle cap structure of the present utility model opened/closed process without Bottle cap need to be rotated a few, thus its application is more convenient.

Specific embodiment

The utility model is further described with the following Examples.

With reference to Fig. 1, Fig. 3, the drinking water bottle cap structure that the present embodiment is provided includes bottleneck（It is not shown）And bottle cap.In bottle cap Portion has cavity, and its cross section is round rectangle, and the radius of fillet is a, a=0.6mm（See Fig. 5）.Bottle cap madial wall is not provided with Screw thread, but smooth surface.The foot of bottle cap is provided with four separation cracks 2.Separate crack 2 be rectangle, its length direction with Bottle cap it is axially in parallel.

With reference to Fig. 2, Fig. 5, 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, snap arm 1 is located at two fillets of bottle cap relative angle.

With reference to Fig. 3, Fig. 4, the end of snap arm 1 has towards projecting inward grab 13.Bottleneck has corresponding with the shape of grab 13 Draw-in groove（It is not shown）.Grab 13 has the locking surface 14 for blocking bottleneck draw-in groove, and locking surface 14 is with the angle of bottle cap axial direction B, b=80 °（The axial direction of bottle cap is parallel with the bearing of trend of bottle cap side wall）.The end of snap arm 1 has the unlatching for breaking snap arm 1 into two with one's hands Chamfering 15.

With reference to Fig. 2, 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.

With reference to Fig. 3, Fig. 4, the drinking water bottle cap structure of the present embodiment includes reinforcing ring 3, and reinforcing ring 3 is set in bottle cap outside Wall.The inner side of reinforcing ring 3 has protuberance 31, and the outside of snap arm 1 is provided with pit 12 corresponding with the shape of protuberance 31.The outside of snap arm 1 Slippage slot 11 is additionally provided with, slippage slot 11 aligns with pit 12 on the circumferencial direction of bottle cap.Protuberance 31 can match somebody with somebody with slippage slot 11 Close, realize that reinforcing ring 3 is slidably connected with bottle cap.

The occupation mode of the drinking water 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 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 piece 4 tightly clamps the edge of bottleneck, bottleneck is formed liquid-tight envelope with bottle cap.Then, that reinforcing ring 3 is pushed into its is convex Go out the pit 12 that portion 31 enters snap arm 1 from slippage slot 11（As shown in Figure 4）, reinforcing ring 3 is fixed with respect to bottle cap.In reinforcing ring 3 Fixation under, grab 13 effectively blocks the draw-in groove of bottleneck, realizes closed closure；

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 In 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 with bottleneck Draw-in groove departs from, you can bottle cap is taken out from bottleneck.

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.
