Query: A Better Solution Than Plastic

I ordered the "AUTOSEAL" drink containers for my wife. She travels locally, but does not enjoy the products served st the local fast food bistros. Her home made concoctions stay cold for over 6-8 hours in these containers despite the heat buildup during stops and visits. The top has never leaked despite being left on its side in the car, dropped to the asphalt, and shaken badly during a one hour rough water boat ride. Sometimes the tops are hard to start, but turning them backwards until they seat solved that problem. I would totally recommend these vacuum insulated containers to anyone. I wish there were even larger capacity ones like the old thermos jugs for family outings.
