I've looked for ways to store my 12oz bottles of Quickleen and Quickcare in a storage compartment right-side-up to prevent any spillage possibilities.
I finally used commercial velcro on the bottoms of 2 koozies and they stay put and the bottles stay in them just fine. Just a thought .......
Oh: You need to use the complete molded ones - not the ones that have holes in the bottoms and fold up. They won't work nearly as well. I bought mine from Amazon. They are "heavy duty" and are much thicker than most you find at WalMart, etc.
