The sealing cover is characterized in that a third convex ring is arranged above the sealing cover, a fourth convex ring is arranged below the top cover, and the third convex ring is in interference fit with the fourth convex ring. The edge of the third convex ring is of a concave structure, the edge of the upper half section of the lower sleeve is of an L-shaped structure matched with the concave structure, and the L-shaped structure is clamped in the concave structure to enable the inner plug to be connected with the lower sleeve.

The side wall of the outer cover is provided with a stripe groove which is convenient for a user to grab and rotate the outer cover.

The top cap joint is at the top of enclosing cover, need pour into or pour liquid in the bottle, only need take off the enclosing cover alright take out the top cap with the top cap together.

The inner wall of the lower sleeve is provided with a plurality of anti-rotating pieces.

The utility model has the beneficial effects that:

1) the first seal formed by the outer cover mounted on the inner plug and the second seal formed by the sealing cover in close fit with the opening of the lower sleeve are matched to form a multi-point sealing structure, so that the sealing performance of the bottle cap at continuous high temperature is ensured.

2) The enclosing cover and interior stopper design become an organic whole, when pouring or pouring out liquid, only need take off enclosing cover, top cap, open sealed lid through the pull ring and can pour into and pour out liquid, avoid because of direct and the bottle plug contact of finger.
