Two drive lugs promote two spacing lugs, and the atress is more stable, and is rotatory more smooth and easy, difficult emergence jamming phenomenon.

Preferably, an annular supporting surface is arranged on the outer side of the upper end of the connecting sleeve, a limiting convex ring is arranged on the outer side of the connecting ring, and a blocking ring is sleeved on the connecting ring and positioned between the limiting convex ring and the annular supporting surface. When the cap is not opened, the upper end of the blocking ring is weakly connected with the cap, and when the cap is rotated to be opened, the blocking ring is limited by the limiting convex ring and is separated from the cap; whether the cap is opened or not can be judged through the blocking ring.

Preferably, a lower stop ring is arranged at the upper end of the connecting sleeve, and a lower sealing groove for sealing the bottle mouth is formed between the lower stop ring and the connecting sleeve; the bottom surface of block is equipped with the upper stop collar, be equipped with between upper stop collar and the block and be used for the sealed last seal groove of go-between upper end. The lower sealing groove increases the sealing performance of the connecting sleeve and the bottle mouth, and the upper sealing groove increases the connecting sealing performance of the cap and the cap base.

Preferably, the edge of the top surface of the blocking film, which corresponds to the spine part, is provided with an annular weakening groove. The setting of annular weakening groove makes to separate the thickness of barrier film in this position and reduces to make spine portion can follow this position more light cut apart and separate the barrier film, resistance when reducing the cutting.

Preferably, the bottom surface of the cap is provided with a separation sleeve, the lower end of the separation sleeve is abutted to the barrier membrane, and the solute storage cavity is located in the separation sleeve. The solute storing cavity is arranged in the isolating sleeve, the solute is stored in the isolating sleeve, the solute is completely isolated from the cutting ring, and the cutting ring is prevented from being blocked in rotation due to the existence of the solute (the rotation resistance of the cutting ring can be increased when the powdered or granular solute enters the threaded connection part), so that the cutting ring is more stable in rotation.

Therefore, the utility model discloses convenient to use, the smooth and easy beneficial effect of solute blanking have.
