Technical Field

The utility model relates to a quick-opening cup cover of a container.

Background

The cup cover of the container, particularly a water cup, is generally screwed on the port of the cup body through threads, and the cup cover with the structure can be screwed down or unscrewed only by rotating a larger angle, which is inconvenient. The screw is not tightened, water leakage is easy, and the screw is not easy to unscrew when being tightened too much.

The invention patent with the publication number of CN 2851143Y discloses a push-press type locking bottle cap, which comprises a shell, a lining, a bottle stopper, a pressure spring, a top cap and a locking mechanism, wherein the locking mechanism comprises a sliding sleeve and a locking hook arranged on the side wall of the lining, the locking hook has elasticity in the radial direction and can be radially ejected and retracted, the sliding sleeve can axially move, and the lower end of the sliding sleeve is provided with a driving lug for driving the locking hook to eject and retract. When the bottle cap is used, the bottle cap is sleeved on a bottle mouth, the bottle cap shell is pressed downwards, the driving lug is positioned below the hook end of the lock hook before pressing, the lock hook is in a natural state, and after pressing downwards, the sliding sleeve moves upwards relative to the bushing, so that the driving lug pushes the hook end of the lock hook to pop out inwards and radially to hook a bottle mouth flange, and the bottle cap is locked; when the bottle cap is opened, the top cover is pressed down, the top cover drives the sliding sleeve to move downwards, the driving lug moves downwards along with the sliding sleeve to leave the locking hook, the locking hook rebounds outwards to reset and is separated from the bottle mouth flange, and the bottle cap can be taken down at the moment.
