If you are not trying to stick the inside of the tube to something else, does it really matter, LOL
But of course as you and everybody else knows, the glue requires contact with air to set.
Edit:- fact is, all the people who said it needs oxygen to harden are completely wrong, and those who said it needs air are in fact correct. Without getting too technical, as a chemist I can tell you that in fact it is oxygen inside the tube that prevents the glue from sticking to the tube. This is the complete opposite of what most have said. (Also not a chemical lining that was also suggested.) The hardening process is dependant upon a reaction with moisture, and as we all know air contains moisture. So it is the oxygen in the tube that prevents sticking to the side of the tube, and moisture in the atmosphere, or air, that causes the hardening reaction. So there, na na na
Forgot to mention, you know with a tube of super glue at some time during use you always get a fart of air with no glue coming out, and you think it wasn't full and you got ripped off. No, that's just some of the oxygen coming out that was put in to prevent it sticking to the side of the tube. It needs moisture to set, oxygen prevents solidification of the chemicals in super glue

Several factors:
They treat the inside of the tube with a specail chemical that dosen't allow it to stick. Also, before super glue or any type of glue can start to bond, it needs to mix with oxygen.

Super glue, although a very good adhesive, doen not work on certain substances, like certain plastics. One can always design the tube from similar materials

Well if you think about it, there would be a layer of glue on the inside of the tube. If you squeezed out all that you could out of the tube, then cut it open, I guarantee that you would find a small layer of glue inside.
But as far as the entire tube of glue not being stuck, that is due to no oxygen. :)

Because there's a cap on the bottle, the air causes it to dry, and if there is no air getting to all the surface area of the glue, it won't dry...Silly!! ;)

I have no idea but have a star for an interesting question unlike some of the rubbishy ones we get on here,

the chemical reaction of it sticking only works with oxygen added....... take the lid off & it will stick to the inside.

It doesn't dry unless it comes in contact with the air.

It needs air to harden

Because it's been specially engineered to only stick to fingers, eyelids and dubious human appendages!
