A storage container assembly includes a container and a lid. The lid includes a top lid, a button, a gasket, a gasket pusher, and an arm. The button is moveable in a first axial direction between a projected position in which a top surface of the button is offset from an upper surface of the lid and a depressed position in which the top surface of the button is nearer to the upper surface. The gasket is moveable between a contracted state and an expanded state. The gasket pusher is moveable in a second axial direction, which is transverse to the first axial direction, and pushes the gasket. The arm operatively connects the button with the gasket pusher. Movement of the button from the projected position toward the depressed position results in pivotal movement of the arm and moves the gasket pusher in the second axial direction.
