ABSTRACT:
A container closure with a screw cap that after the opening of the container remains attached to the same, by means of a hinge. A sealing ring is joined to the lower end of the cap and rotatably connected to the container, but impossible to remove, as the inner diameter of the ring is smaller than the outer diameter of a bulge on the container. Between the cap and the sealing ring is a breakable connection and an unbreakable part serving as the hinge. When the cap is unscrewed the sealing ring is after a while obstructed by the bulge, which causes the breakable connection to break, whereafter the unscrewed cap can be swung aside around the hinge so that the contents of the container can be freely poured out.
