A closure is disclosed for use with a tubular container having an open end with a cylindrical connecting bead at the open end. The closure includes a circular wall and a peripheral connecting flange surrounding a peripheral edge of the connecting bead so that the circular wall closes the open end of the container. First and second coaxial reinforcement ribs depend downward from the circular wall to provide suitable reinforcement while eliminating crevices on the circular wall.
