Abstract
A plastic screw cap includes a cylindrical cup provided with an internal thread and with a tamper-evident ring which is coupled to the rim of the cup by means of a plurality of bridges forming a fracture line; the ring has a collar or expansion for retaining it below an annular raised portion of a container whereto the cap is applied. Incisions are formed on the outside of the tamper-evident ring, the incisions do not cross the entire thickness of the ring and allow an elastic radial expansion of the ring, such as to pass beyond the annular raised portion during the application of the cap to the container.
