One-button-opened cup cap and cup

Abstract

The present invention discloses a one-button-opened cup cap and cup. The cup comprises a cup body and a cup cap partially inserted into the cup body. The cup cap comprises a pressing assembly, a water shutoff assembly and an exhaust assembly. The water shutoff assembly comprises a main cap, a sealing cap and a linkage component. The pressing assembly is connected with the main cap. The linkage component is provided with an air outlet hole plugged by the exhaust assembly. The pressing assembly is longitudinally pressed under the action of external force to act on the exhaust assembly and unblock the air outlet hole. The main cap restricts the pressing assembly from positioned at two longitudinal positions different in height. The present invention has the advantages of need of only pressing the pressing component when disconnecting the cup cap from the cup body, and simple and quick disconnection operation.
