Abstract
A safety-type dispensing closure can be constructed using a spout rotatably mounted on a closure body so that it is capable of being rotated between open and closed positions and using a retainer movably mounted on the retainer body. The retainer used in such a closure is capable of being moved to a position in which it does not interfere with spout rotation between the two positions specified and to other positions in which it blocks such movement. The retainer used is preferably a ring rotatably mounted on the closure body so as to be conveniently accessible and so as to appear as a part of the body.
