Historical Background
The concept of child-resistant packaging was formalized in the United States with the enactment of the Poison Prevention Packaging Act (PPPA) in 1970. This pivotal legislation mandated that specific substances be marketed in special packaging designed to reduce the risk of accidental poisoning among children under five years of age. The PPPA aimed to address alarming rates of childhood poisonings, prompting a response from regulatory bodies such as the U.S. Consumer Product Safety Commission (CPSC) and the Environmental Protection Agency (EPA).
Child-resistant packaging is defined by the CPSC as packaging that is significantly difficult for children under five years to open while remaining accessible to adults. The standards governing this type of packaging have evolved over the years, with the effectiveness of child-resistant closures being periodically reviewed and updated based on new research and technological advancements.
Initial testing protocols were established to evaluate the functionality of child-resistant closures, which primarily rely on the inability of young children to perform simultaneous push-and-turn movements—actions that are typically required to open such packaging. These measures have proven effective, as studies indicate that the PPPA has led to a significant reduction in both poisoning incidents and fatalities.
The EU has also recognized the importance of child-resistant packaging, implementing its own regulations, such as the Classification, Labelling and Packaging (CLP) Regulation, which includes requirements for child-resistant features on hazardous materials. Public health campaigns, such as those launched by Public Health England, have further raised awareness regarding the risks associated with unintentional child poisoning, emphasizing the importance of safe packaging solutions.
As of June 23, 2025, Title 16 of the Code of Federal Regulations continues to serve as the regulatory framework for child-resistant packaging, reflecting ongoing adaptations to ensure that safety standards meet contemporary challenges.
Design Principles
Designing child-resistant packaging requires a thoughtful approach that balances safety for children with accessibility for adults. This necessitates the incorporation of various design principles and practices aimed at achieving effective child-resistance while ensuring usability for adult users.
