Abstract
A tamper-evident closure for a container mouth, comprising a cap and a retaining ring arranged under the cap for retaining the closure on the container, the cap is separable from the ring, the cap and ring are joined by a pair of arms, the arms are non-frangibly connected to a common root at one end, the other end one of the arms is non-frangibly connected at a circumferentially clockwise location from the root and the other end of the other arm is non-frangibly connected to a circumferentially anticlockwise location from the root, whereby the arms permit axial separation of the cap from the ring and assume a generally V-form configuration when doing so and whereby the cap remains tethered to the ring.

A tethered closure comprising a cap and a retaining ring, the cap and ring being joined by a hinge area and two flexible links, the ring is made by non-continuous slitting which leaves several breakable bridges between the ring and the cap, the hinge area and two flexible links are formed by first and second superposed horizontal slittings, the first slitting defines breakable bridges and also a wider sector creates one link that serves as a hinge area at the opening of the cap, the second slitting defines the flexible links which allow a deformation to help at the opening at the opening of the closure, in which the closure has an open configuration in which the hinge is an open trapezoid with the two flexible links forming the inclined sides of the open trapezoid and the ring and the cap forming the other two opposing sides of the open trapezoid.
