The purpose of this design project is to propose a novel, affordable, and effective design to replace current opioid packages/containers with enhanced child-resistant and senior-friendly features in an effort to curb the opioid epidemic in the United States. The focus is on refining and improving the child-resistant features of current opioid packaging techniques while at the same time discouraging opioid misuse and abuse in adults using a novel self-closing and dose-controlling opioid packaging design.
