Pen Cap Holes: A Simple Lifesaver You Didn’t Know About: Have you ever been curious about that little hole in the top of your pen cap? It seems like a minor detail, but it’s the result of thoughtful scientific design intended to save lives.


Many believe the hole in the pen cap will equalize air pressure or stop the ink from drying up. While the cap does help in these regards, the actual reason behind its perforation goes deeper.


The reality is many people have a habit of chewing on pen caps. In some unfortunate cases, this leads to accidental swallowing of the cap, which could get lodged in the person’s airway, causing a fatal choking hazard. Reports suggest that this issue was so severe that around 100 people in the US died each year from asphyxiation after swallowing pen caps.


Thus, manufacturers decided to innovate. They introduced the concept of a hole in the cap to allow air to pass through, reducing the risk of choking if the cap was accidentally ingested. This life-saving design was soon adopted by ballpoint pen manufacturers everywhere.
