Patent ID: 8919083

Claim:
A method of customizing the dispensing from a pharmacy of a prescription pharmaceutical for a customer in a pharmaceutical container, the method comprising the steps of: providing a quantity of a pharmaceutical system at the pharmacy, the system comprising: a non-child resistant cap shaped to screw on and off the container, and a child resistant element that is separate from the non-child resistant cap and is configured so as to be able to be permanently assembled with the non-child resistant cap to permanently convert the non-child resistant cap to a child resistant cap, wherein the child resistant element when assembled with the non-child resistant cap will rotate on and relative to the non-child resistant cap in a first mode of operation in which a depressive force is not applied to the child resistant element, and wherein the child resistant element when assembled with the non-child resistant cap will engage the non-child resistant cap and drive the non-child resistant cap in a rotating motion to unscrew the non-child resistant cap from the container in a second mode of operation in which a depressive force is applied to the child resistant element; determining whether the customer wants the child resistant cap or the non-child resistant cap on the container for the prescription of the customer; dispensing the prescription pharmaceutical in the container having the non-child resistant cap when the customer does not want the child resistant cap; and permanently non-reversibly converting the non-child resistant cap to a push-down-and-turn child resistant cap by assembling at the pharmacy the child resistant element with the non-child resistant cap and dispensing the prescription pharmaceutical in the container having the push-down-and-turn child resistant cap when the customer wants the child resistant cap.
