Bic finally responded to one of the big questions: what serves the small hole with Bic pens that feature on your side? This is demonstrated by a specific section on the website of the company that unveiled the mystery. As indicated, all about science.
“The hole serves to equalize the pressure that exists outside of the pen with which is inside,” explains the company. Apparently not for this small opening our pen Bic could explode when subiésemos-for example on a plane. However, this is not its only use, as it also serves to make, due to the sensitive changes in pressure, the ink does not come out.
On the other hand, on the company website also explains why the covers have a hole at the end. In the words of Bic , as well as serving to prevent leakage, also well prepared to meet international safety standards that attempt to minimize the risk of drowning if a child swallows this piece. Thus, little could keep breathing although ingested and he would tarry wedged in her throat.
Finally, have you noticed, too, that the tube where the ink is stored usually the end of empty ? This does not make Bic to save on costs. When loaded ink to the edge this is would spread on your hand because the ink is a material that expands when heated. Therefore, the 37th half that usually have our hands would be enough to ruin everything.
