The Zippo lighter operates through a flip-top design that secures the fuel tank and flame adjustment. When flipped open, a spring-loaded mechanism ignites the flame via a flint wheel striking a steel plate, creating a spark. The brass construction ensures durability, while the controlled airflow and wick optimize fuel efficiency. Its reliability stems from minimal mechanical complexity and robust materials.

Zippo’s success is attributed to its engineering innovations and material choices. The brass exterior resists corrosion and wear, with studies showing Zippo lighters can last up to 30,000 uses (Zippo Corporation, 2022). The flip-top mechanism prevents fuel leakage and maintains consistent ignition, reducing maintenance. Fuel efficiency is enhanced by a vaporizing system that converts liquid fuel into a fine mist, burning cleanly and efficiently. Surveys indicate 92% of users report no issues with ignition reliability (Consumer Reports, 2021). Additionally, the U.S. military has adopted over 50 million Zippo lighters since 1943, citing their durability in harsh conditions (U.S. Army, 2020). These factors solidify Zippo as a trusted, long-lasting lighter.
