A cap assembly for a container comprises a cap and a body coupled to the cap. The body includes a peripheral wall and a valve seat. The valve seat includes a first side facing the cap and a second side facing away from the cap. A first check valve having an elastic valve body is positioned at the second side of the seat. A second check valve having an elastic valve body is positioned at the first side of the valve seat. When a pressure at the first side of the valve seat exceeds a pressure at the second side of the valve seat by a first predetermined value, the first check valve opens; and when the pressure at the second side exceeds the pressure at the first side by a second predetermined value, the second check valve opens.
