Abstract
A closure device for a bottle or the like wherein the closure device which, in its closed condition, comprises a pressure ring and a claw cap is fabricated of one-piece in that the pressure ring is connected with the claw cap by means of webs which are disposed between its engagement portions and the roof wall of the claw cap. By pressing the pressure ring downwardly over arms and claws of the closure cap, while tearing the webs, the claws are pressed against the underside of a mouth bead of the neck of the bottle and are pressed into a constricted portion of the bottle neck. By rotating the pressure ring such that its engagement portions or parts depart from the U-shaped claws and by lifting the same it is possible to remove the closure cap from the dispensing or pour opening of the bottle neck, since the engagement parts upwardly raise the claw cap at a lower edge of the roof wall of such claw cap.
