What Is a Child-Resistant Cap?
A child-resistant cap, often referred to as a CRC, is a type of closure designed to prevent children under five from opening containers containing hazardous substances such as medicines, vitamins, or chemicals. At the same time, it must remain accessible for adults, including the elderly.
Key Requirements for a Child-Resistant Cap
Compliance with Standards:
In the United States, the Consumer Product Safety Commission (CPSC) requires compliance with 16 CFR 1700.
In Europe, the EN 14375 standard applies for medicinal products.
The cap must pass standardized child and adult testing protocols, ensuring children cannot easily open it while adults can.
Design Considerations:
Push-and-Turn Mechanism: Requires pushing down and twisting simultaneously.
Squeeze-and-Turn Mechanism: Requires squeezing specific points on the cap while turning.
Other Mechanisms: Innovative designs may combine multiple steps to ensure safety while remaining user-friendly for adults.
Material and Durability:
High-quality plastics such as PP (polypropylene) are commonly used for their durability and resistance to breaking under pressure.
The material must withstand repeated opening and closing without losing its child-resistant properties.
Testing Protocols:
Child tests: Typically involve a group of children aged 42–51 months attempting to open the cap within a set timeframe.
Adult tests: Adults must be able to open and reclose the container without excessive difficulty.
Caps that fail these tests cannot be marketed as child-resistant.
Labeling and Instructions:
Clear labeling is required, indicating that the container is child-resistant.
Instructions for proper opening should be printed on the package to help adults operate the cap safely.
Why Choose High-Quality Child-Resistant Caps?
Using certified child-resistant caps protects both consumers and brands. Non-compliant caps can lead to serious safety incidents and legal liabilities. High-quality caps also enhance brand credibility and trust, especially for pharmaceuticals, dietary supplements, or chemical products.
