Glue has to dry to become effective. You join the parts together then wait for it to dry before handling it. Some, like superglue dry fast, others take minutes, hours or days, depending on the kind of glue. In the bottle, there isn't much air, so the glue cannot dry.
Unfortunately, once you open it and use some, the glue you use is replaced by air, and the life of the glue is reduced. Eventually you will find the remainder dried up in the bottle and stuck to it.
Because it needs exposure to air to solidify and stick.
Another great and puzzling question. Why doesn't glue stick inside of the glue bottle. Glue on paper: As the glue connects with oxygen it becomes sticky and if left to dry in this oxygen it becomes hard and keeps multiple things together. Glue inside the bottle: Glue doesn't stick inside the bottle because the chemicals within the glue is triggered by oxygen (what we breathe) so when the glue bottle is opened it triggers the chemicals to make it sticky. That's why if a bottle if left out with no cap the glue becomes quite hard. Glue won't completely stick unless it's dried, and because inside the bottle, the glue is still air locked in and not dried, it doesn't stick.
Glue bottle because glue sticks will not be strong enough..and the paper is thick so the glue shouldn't leak through.
Not really, it's just another way to glue things.
Cyanoacrylate (super glue) doesn't stick until it dries and sets up.ANS 2 - Any glue needs to partially evaporate in air to stick. If kept in an air tight bottle it can't set.

Glue doesn't stick to the bottle because, in order for glue to become sticky it has to dry. There's no air circulation in a closed bottle so glue can't dry. If you're thinking, "But what if I leave the glue bottle open! Why doesn't it dry?" It's because there is a lot of glue in the bottle. Not just a thin layer. Just like when you're glueing something and you're not supposed to use that much glue because it won't dry.
Because most glues are air drying and the is very Little air in the bottle.
using tape. seriosly what kind of question is that.
Never tried that. Stick a bottle in the freezer and see.
because using a bottle makes a huge mess
Glue is made up of a substance that sticks to things and a solvent that keeps it liquid until you want it to stick. When you put glue on a piece of paper, the solvent gradually evaporates until the glue becomes sticky. When the glue is in a bottle, there is a space inside the bottle above the liquid that is full of air. So why doesn't the glue dry out? Well there's a limit to the amount of solvent that can evaporate to fill the space in the bottle. Once the space is full of solvent gas, no more solvent evaporates from the glue and the glue stays runny
When you squeeze the glue out of it's container, it makes contact with air, therefore evaporating the water molecules and drying it onto the surface of which you are gluing. So the reason why glue doesn't stick to the inside of the bottle is merely because the top is (hopefully) sealed, denying air access to the glue inside, so the water molecules remain intact. Hopefully you found this resourceful.
