The Hidden Purpose of the Two Holes in Bic Pens Uncovered
The two holes in a Bic pen serve important functions related to safety and performance. The hole in the cap is a critical safety feature designed to prevent choking. If the cap is accidentally swallowed, the hole allows air to pass through, reducing the risk of suffocation. This design element is in line with safety regulations in various countries, ensuring that the pen is safer, especially for children who might play with it.
The second hole, located in the barrel of the pen, is there to help equalize pressure inside the pen with the external environment. This prevents the ink from leaking due to pressure differences, which can occur during air travel or in environments with varying atmospheric conditions. By equalizing pressure, the hole ensures a smooth and consistent flow of ink, maintaining the pen's writing performance.
