Disclosed is a container cover having an elastic shutter enhanced to suppress excessive elastic deformation and to prevent defective shutoff control due to elastic fatigue even after a long-term usage. The container cover comprises a body coupled to the peripheral part of the upper opening of a container in which contents are stored, and having a discharge opening formed in one side and opened to discharge the contents of the container to the outside; an elastic shutter loaded in the body to close the discharge opening, having multiple shutter pieces formed of an elastic material, and capable of being deformed between a first shape in which a gap is formed by elastically deforming the multiple shutter pieces and a second shape in which the gap is closed by elastically restoring the multiple shutter pieces; and a shutter restriction unit for restricting the excessive deformation of the multiple shutter pieces. |
