A tamper-evident closure cap construction having a cap body part for attachment to a container neck, a closure cap part, and a hinge connecting the closure cap part to the cap body part. The latter has an upper discharge opening, and the closure cap part is movable between a closed, sealing position covering the discharge opening, and an open, discharge position wherein the closure cap part is removed from the discharge opening. There are selectively manually operable locking components for locking the closure cap part in the closed, sealing position. The manually operable locking components have a first position corresponding to a closed, but unlocked condition of the closure cap part, and a second position corresponding to a closed and locked condition of the closure cap part. The components, once locked manually, are permanently retained in the second position so as to prevent tamper-type removal of the closure cap part from the cap body part.
