Final answer:
Jay M. Arena created a child-resistant bottle cap to prevent children from accidentally poisoning themselves by accessing harmful substances in containers.
Step-by-step explanation:
The type of bottle cap devised by Jay M. Arena, director of the Duke Poison Control Center, was designed to protect children from accidental poisoning by making it difficult for them to open containers of potentially dangerous substances. This innovative cap is known as a child-resistant closure or a safety cap. The cap requires a certain amount of coordination and strength to open, which most young children lack. These safety measures have been applied to a wide range of products, including soft drink bottles, water bottles, salad dressing bottles, peanut butter and jam jars, and even small consumer electronics that might contain small batteries or other hazardous substances.
