A storage container assembly includes a container having an opening and a lid for covering the opening. The lid includes a top lid, a button, a cam, a base, a lower plate and a gasket. The button is moveable in a first axial direction with respect to the top lid between a projected position and a depressed position. The cam is configured to cooperate with the button such that the button maintains the depressed position when moved from the projected position to the depressed position, and the button remains in the depressed position until pressed again while in the depressed position. The lower plate is connected with the top lid. The gasket is moveable between a contracted state and an expanded state in response to alternate actuations of the button, and the gasket is interposed between the lower plate and the top lid.
