I don't understand why anyone would buy tricky gadgets for $ to preserve their glue investment when simple storage will solve their glue curing problem. My post above is nearly without any cost. (My wife also thought the little bottle condoms were cute, but didn't see any use for them ....) Stan's comment was sure funny!
I don't have any problem any more with glue drying in my bottles since I changed my storage method at nearly no cost.
I often take glue from a storage bottle and put it into a roller dispenser and use it that way. What I don't use in the roller bottle, I put back in the storage bottle and keep for next time. I'd rather buy glue to use for woodworking instead of buying bottle tricks to not impress the LOML.
