A safety closure to deter children from opening containers used to store potentially dangerous substances. The closure includes a skirt which is permanently fastened to the container and freely rotatable thereon, an overcap for sealing the container opening and a locking mechanism for securing the overcap to the skirt. The skirt has a generally cylindrical configuration with a portion of the locking mechanism either on the inside or outside of the skirt. The portion of the locking mechanism on the overcap is disengaged from the portion on the skirt when the overcap is rotated to a particular position with respect to the skirt. However, the overcap will remain in a locked position if the skirt is rotated together with the overcap.
