ABSTRACT:
The version of the container of my U.S. Pat. No. 3,991,895, which provides a dual latching arrangement so that, by a first turning of the cover during the latching operation, a condition of easy opening for adults is obtained, and, if desired, a hard-to-open, child-resistant condition is obtained with a further turning of the cover, is improved by the provision of a positive stop at the end of the first turning of the cover to prevent inadvertent latching into child-resistant position and to require a positive, downward displacement of the cover before it can be turned into child-resistant condition.
