Taking apart a BIC lighter to understand how it works

They are the benchmark lighter worldwide: BIC lighters hold a very comfortable position among smoking accessories. Little wonder, since they have been around since 1973 and have hardly aged a day. But do you know how this famous lighter works? Here is an explanation.

The twelve “body parts” of the BIC lighter

1. The wheel

Made of serrated steel wire, it turns in order to create a spark. To do so, it has to be driven with enough force and speed.

2. The flint spring

The flint spring presses on the flint in order to create the sparks needed to light a flame.

3. The stem

This is one of the three components that open and close the flow of gas coming from the valve. When the fork is released, the gas supply is cut off. Quality control on the stem and seal parts (the sub-assembly) is carried out rigorously, using video inspection.

4. The valve

This is the sub-assembly that regulates the gas flow and releases a constant quality of gas, so as to obtain a steady flame of the chosen height.

5. The body

The body is the ultrasonically welded plastic casing. It protects the gas tank.

6. The ball

The ball seals the gas tank once it has been filled.

7. The base

This is a plastic part ultrasonically welded to the body. Together with the ball and the body, it forms the tank.

8. The flint spring

It keeps the flint in contact with the wheel, even when worn. It helps to generate sparks.

9. Fork spring

Together with the stem and the fork, these are the components that manage the gas supply from the valve.

10. The fork

The fork has exactly the same function as the fork spring.

11. The hood

The hood is made of steel. It provides protection from the wind and the heat.

12. The safety guard

This is a child safety device fitted to all the brand’s lighters.
