CA 2590786

A closure for capping a container neck finish by threaded engagement includes a unitary, molded plastic inner cap designed for threaded connection to the neck finish and a unitary, molded plastic outer cap designed for threaded connection to the inner cap. The container neck finish includes an annular series of ratchet teeth positioned below the threaded portion of the neck finish and the inner cap includes a cooperating plurality of ratchet teeth to prevent removal of the inner cap from the neck finish once fully assembled. The inner cap includes an integral pouring spout defined by an inner spout wall and the inner and outer caps cooperate to create a liquid-tight plug seal. A tamper-evident arrangement is provided by the connection of the inner cap and the outer cap, resulting in the fracture of frangible portions as the outer cap is unscrewed from the inner cap to open the container.
