ABSTRACT:
A closure device for cans having a beaded edge and a cover with a wall part to be torn-off for formation of a pouring opening, the closure device being provided at two opposite ends of a base body with flanges directed toward each other, which grip under the beaded edge of the can. One of the flanges is elastically deflectable, the other flange is formed rigid, such that the closure device can be pressed onto the can from above like a snap-on-cap. A sealing ring is guided at the base body at the side disposed opposite to the pouring opening such that this sealing ring grips around the exit opening in a compressed state upon placing of the closure device onto the can, the sealing ring being disposed tightly at the cover of the can. Selected FIG. 4.
