Detailed description of the invention

Refer to shown in Fig. 1 to Fig. 6, that show the concrete structure of the preferred embodiment of this utility model, it it is a kind of safety exhaust bottle cap, including circular top 10, the shirt rim 20 that integrally downwardly extended by this circular top 10, the cut off machine arranged below 30 of this shirt rim 20, this cut off machine 30 lower end connects anti-theft ring 40。

Wherein, being provided with female thread 21 inside described cut off machine 30, this female thread 21 is breakaway-element structure, and it includes the thread segment 211 that many certain distance are arranged, and is provided with steam vent 212 between adjacent two screw threads are disconnected。Described steam vent 212 is provided with the boss 213 that can increase unlatching dynamics。In bottle, the air pressure of gaseous beverages is more than ambient pressure, when bottle cap outwarded winding by needs, gas is discharged from steam vent 212, there will be bottle cap when bottle cap unscrewing is too fast and fly off phenomenon, after this utility model adds the boss 213 of symmetry in the middle of screw thread, strengthen the unlatching dynamics of consumer, it is prevented that consumer's open bottle cover is too fast and causes air pressure too high and bottle cap flies off。
