ABSTRACT:
Packaging having a combination lock closure is rendered child resistant in a manner that maintains ease of adult use and economy of manufacture while providing adequate protection of child health. The technique comprises the steps of selecting an appropriate child resistance effectiveness, selecting an appropriate older adult use effectiveness, determining a probability of random opening that correlates with the selected child resistances effectiveness and provides at least the selected older adult use effectiveness, and configuring the combination lock closure to present to the package user said probability of random opening. Configuring the closure may include providing a plurality of tumblers, only one of which is accessible to manual manipulation.
