There may be times when you may want an insulated water bottle to keep liquids hot or cold. I am loving my Zohirushi bottles. We have two. One is a sippy one that my wife has and mine is a more thermos like one. They both hold 17 ounces. Here's the sippy And the pour one Those are stock photos. I prefer the pour type. I wouldn't use the sippy one while driving anyway. Those bottles keep liquid hot for a long time. After eight hours, it is still burn your mouth hot. I did a long term test where I made hot tea and let it sit for various lengths of time, during which, I would pour some out and drink. After three hours, it is scalding McDonalds in your lap hot. At eight hours, still hot enough to burn your tongue and mouth. But maybe no lawsuit. At twelve hours, it is still too hot to gulp, but great for sipping. At nineteen hours (my longest) with just a capful or two of tea in there, it was still steaming hot, but you could drink it down. It more than exceeds my expectations. Now I am resting to see how long the ice in the ice water mix will last.
Still have ice after over 18 hours. This included periodic drinking, finishing one bottle of iced water. I topped the remaining ice off with more water and took a few drinks from that. Amazed that the original ice is still there and going strong.
I have one of those Thermos food containers, they're amazing. Wife made me lunch for work and it was still burning hot after 5 hours
Nice! Always a handy thing to have around, too! Something that I've been wondering about.....if you put water into an insulated cup (or even a cooler), do you have to worry about it freezing, if it's left out in your vehicle?
Not for an extended time. It will freeze, sooner or later, but the insulation slows down the transfer of heat, in or out of the liquid.
That's what I figured. My vehicle is a soft-top Jeep Wrangler, and I want to be able to leave water in there.....but with the temps here reaching 100+ in the summer, and below freezing in the winter (best of both worlds, eh?), I don't want to deal with the mess if it freezes and blows up! Seems anything that's good for the hot months won't work well for the cold months, and vice-versa. I've looked into some flexible bottles, but they're pricey, and don't hold much more than a quart or so, so they're not really economically viable. Short of hauling a couple gallons from the Jeep to the house when I get home, then back out to the Jeep every time I want to go somewhere, I'm a bit stymied.
Assuming you drink whatever you have in the bottle, hot or cold, within a day or two, I don't foresee a problem.
Water increases in size by %9 when frozen. Just don't fill the bottle full, and squeeze the sides in a little when you seal it. It will be fine. (old Boy Scout trick)
