Pen caps contain ventilation holes to lower suffocation risks
International safety standards mandate airflow channels inside swallowed pen caps
International standard ISO 11540 requires pen cap manufacturers to include a central ventilation hole or air channel. The design safety feature ensures that if a child or adult accidentally swallows a pen cap and it lodges in their windpipe, air can still flow through the opening until medical emergency rescue arrives.
