Abstract: A vessel with a locking lid has a spindle button. The spindle but has downwardly facing button teeth. The lid frame receives the spindle button in a vertical sliding configuration. The actuator gear is mounted under the spindle button in the lid frame. The actuator gear engages the downwardly facing button teeth. The spindle button is configured to move the actuator gear by one step when the spindle button is pressed down. A lid frame inside surface has an upper engagement and a lower engagement. The actuator gear is configured to alternate between the upper engagement and the lower engagement when the actuator gear moves by one step. A spindle body abuts and is biased upwardly against the actuator gear. The spindle body actuates locking arms mounted on locking arm pivots formed on the spindle body.
