Screw-top caps on containers of adhesive can sometimes be tough to remove. The adhesive dries in the threads and the top become virtually glued closed. Ron offers a great tip that will help.
Take the top off and wrap the threads a couple of time around in a clockwise direction with Teflon tape, the same tape you use when doing plumbing work. Then snap the tape off.
Screw the cap back on and you've got non-stick threads! That means you can open the container anytime you want to.
