To keep the pressure equalized. If you have a pen with no hole, and were to take it up in an airplane, or even to the top of a building, the pressure difference could cause the ink to flow out of the pen creating a mess and making writing really messy.
There is a hole in the body of the Compressed polystyrene to equalise atmospheric pressure, for the reasons stated above, however the hole in the top of the lid is to prevent children for sucking the lid into their throat, subsequently this provides an air passage in such a case.
The tip of the pen is the top because that's where you would put the pen cap
The opposite end to where the pen would write
We'll it's the pen bit then the big ball on top with that amazing clicking thing
If it was completely airtight, then the pressure inside would drop, preventing ink flow. Placing a hole in the middle equalises the pressure and controls the flow of ink. The hole, basically, stops the pen from leaking ink.
Methods include:using a lighter or a match to heat the pen which will cause the ink to flow again (be careful not to melt the pen)taking the ink part out of the pen, then blowing hard into it without letting any air escapeholding the top of the pen and shaking itscribbling vigorously on a piece of paper
to stop the ink from drying up

Zero, pen lids don't kill anyone. Ha, take that, Ollie!
The rubber circles around the top of cup lids are buttons to mark what type of drink it is such as diet and other.

you can put them in jars with lids only if you put holes on the top which you can drill in i hope i was a good help
if you are refering to the lids that you see on the streets its that the lid will not fall into the hole, also most piping is circular
I would think that it would be called the pen cap or the cap of a pen. Top of the pen or pen top may also be used. But I don't really believe that the lid of a pen is the correct use of the word "lid" in the phrase.

The spy pen can take pictures by clicking the top of the pen.
