Do ballpoint pens need a cap?

Ballpoints use an oil based ink that does not dry out immediately even when exposed to air.

The hole on the barrel creates the same level of air pressure inside and outside of the pen, allowing the ink to flow into the point. The reason that some BIC® pens have a hole in their cap is to prevent the cap from completely obstructing the airway if accidently inhaled.

Why do BIC pens always leak?

Pens often leak when the temperature is raised. However, the human body increases the heat where the ink becomes liquefied and is pushed to the tip or the end of the pen depending on gravity. No matter how well you cap it, temperature plays a crucial role when it comes to pen leaks.

Do pens leak on planes?

Fountain pens will definitely leak unless you take proper precaution. Fill your pen to the brim. It’s the air that expands and contracts as cabin pressure changes, the change in volume of a liquid is negligible, so the more full your pen is, the better off you will be.

Why do Bic pens have holes in the caps?

Why do pens have caps on them?

The International Organization for Standardization, a federation that sets industrial standards for 161 countries, requires it. ISO 11540 specifies that if pens must have caps, they should be designed to reduce the risk of asphyxiation if they’re swallowed.

Do fountain pens have holes in them?
