Nail adhesive bottles won't open!

[CarrieBeauty]

Hi! I'm using NSI's nail adhesive for tips. I'll use the glue twice maybe three times and it gets stuck and won't open! Very embarrassing the first time it happened as I was doing a clients nails. Lucky I had an extra glue but isn't as good! Any ideas how to stop this happening?
(it's a brush on glue as I think it's easier to apply to tips)

Hi, I find mine welds shut If I have the glue under a lamp while I'm doing a clients nails, also make sure your closing the lid correctly after each nail or the glue may be running down which maybe causing it to glue shut x

Rub some vaseline around the screw threads on the bottle. x
