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.

A closure device for cans having a beaded edge and a cover having a pouring opening formed by removal of a tear-off portion thereof, said closure device comprising: a unitary synthetic resin elongated planar body having a length at least as great as the diameter of said can; an edge web formed at one end of said body and having a curvature equal to the curvature of said beaded edge, said edge web being formed with an inwardly projecting flange for gripping the underside of said beaded edge; a tensioning element formed at the other end of said body opposite said edge web and spaced therefrom at a distance substantially equal to the diameter of said beaded edge, said tensioning element having a formation adapted to engage the underside of said beaded edge and being deflectable for releasing same; a flat extension formed on said body beyond said tensioning element and projecting over said edge of said can; a pair of rigid formations on said body spaced to either side of said tension element and engaging the outer periphery of said beaded edge to cause tension between said rigid formations and said first mentioned edge web; and a seal mounted on said body and adapted to engage said cover around said opening.
