Here is another one of the things that I like to reuse around my shop:
They are Dishwasher Rinse Aid Bottles. The brand is the local store brand but the name brand bottles that I’ve seen are about the same.
What I like about these is that the hole is much smaller than a typical glue bottle. It always seems like when I need a little glue in a small area, the larger opening standard glue bottle gets glue everywhere.
The other advantage is that the glue doesn’t bond to the dispenser. It will dry and stick to the top but I use a metal tool of some sort (screw driver, putty knife, et. al.) and it just flakes off.
