The invention discloses a movable opening lid, which comprises a lid and a drinking device, wherein a water inlet unit communicated with the drinking device is arranged at the bottom of the cover, and a movable unit communicated with the water inlet unit is arranged on the cover, and the movable unit can be operated with one hand to open or close the water inlet unit to ensure use convenience; A sealing element is arranged on the movable unit to increase the sealing performance and prevent the liquid in the container from overflowing after sealing, thus ensuring the good product quality.

A measuring and dispensing device for a flowable material has a cap body configured to be removably secured to a container, the cap body having a bottom wall that extends across the container and has a bottom aperture configured to allow the flowable material to pass from the container into the cap body. A top housing extends over the bottom aperture, the top housing including a top wall having a top aperture. A metering button is slidably mounted within the top housing for rectilinear movement between a closed position and a dispensing position. A metering bore is formed through the metering button, the metering bore being aligned with the bottom aperture in the closed position to receive a predetermined volume of the flowable material, and being aligned with the top aperture in the dispensing position to dispense the predetermined volume of the flowable material. A biasing mechanism is disposed within the cap body for biasing the metering button toward the closed position.
