Description of drawings
Fig. 1 is the structural representation of the utility model bottle cap
The specific embodiment
Below in conjunction with accompanying drawing the specific embodiment of the present utility model is further described.
Figure 1 shows that the utility model bottle cap, comprise body of the bottle lid 1, the inside face of described body of the bottle lid 1 is provided with screw thread, the inside face of described body of the bottle lid 1 and bottleneck 2 outside faces are threaded connection, also comprise a plug 3 that is positioned at bottleneck, the inside top of described body of the bottle lid 1 is provided with a sharp portion 11, and the end of described sharp portion 11 is positioned at the top of described plug 3, and the middle part of described interior plug 3 is provided with a puncture orifice that can be pierced 31.Described bottleneck outside face is provided with a bulge loop 21, is provided with an independently coupling link 4 between the lower end of described body of the bottle lid 1 and the described bulge loop 21.Described interior plug 3 outside faces are provided with a boss 32, and described interior plug is high frequency fused with the top of described bottleneck 2 by this boss 32.The inside face of described bottleneck 2 is provided with draw-in groove 22, and the outside face of described interior plug is provided with the projection of corresponding described draw-in groove 22.
During use, body only need to screw the cap off a bottle, take away coupling link, when screwing on again bottle cap, the puncture orifice place at interior plug middle part will be by the sharp portion bursting of body of the bottle lid inside top, and the liquid that can make like this flows out from puncture orifice, the bottle cap of screwing on when not in use, the puncture orifice place can fit with the sharp portion place again, reaches sealing function.Interior plug boss is in meeting under the high frequency state so that this boss merges the upper edge at bottleneck fully, to reach the bottle seal effect.In beyond the Great Wall the surface projection play the effect of blocking bottle, prevent coming off of interior plug.
