Dispensing closures each having a closure body and a spout rotatably mounted on the closure body so as to be capable of being rotated between open and closed positions can be constructed so as to be incapable of accidental or unintentional opening under normal circumstances by the use of the latch means and a catch means. Either of these means can be located on the body and the other on the spout. These means are constructed so that they will engage one another, preventing undesired spout rotation, upon the spout being assembled in a closed position. By manipulation of the latch means the spout in a closure as described can be rotated from a closed position to an open position once the closure has been assembled with the spout in a closed position.
