Why only stainless steel water cups can be used as thermos? Can other materials be used as thermos cups?
More than one friend has asked the author
about this topic. Today, the author will explain why, but the title is not
strict enough in the strict sense, but in order to let everyone understand the
author at once, the title is set up like this.
What is a thermos cup?
What is a thermos cup? Are there any strict
international requirements for thermos cups?
As the name suggests, a vacuum flask is a
water cup that preserves the temperature. This temperature represents both heat
and cold, which means that the hot water in the water cup can be kept hot for a
long time, and the cold water in the water cup can be kept cold for a long
time. Internationally, there are definitions and regulations for thermos cups.
Pour hot water at 96 degrees Celsius into the cup, seal the lid and let the
water cup stand. After 6-8 hours, open the lid and test the water temperature
at 55 degrees Celsius. It is a qualified thermos cup. Of course, this
regulation was proposed many years ago. With the continuous improvement of
production technology and craftsmanship, some thermos cups can even be kept
warm for 48 hours through changes in product structure and craftsmanship.

How to Choose A Water Bottle
While buying the correct water bottle might not be as exciting as searching for the new mobile phone setup you`ve been lusting after, the choice is still an extremely important one. In some ways, it might be one of the most important purchases you make, because it could be the piece of gear you use most frequently over the course of its lifetime. Little issues like a squeaky lid, heavy materials, or poor lip-to-lid interaction can potentially drive you crazy over tens of thousands of sips. But the journey is worth it: there`s something magical about finding the right one.
Here are my tips for finding the right water bottle for you.
Be Realistic About the End Use
While I could happily geek out on the latest technologies, I don`t think you need to obsess over things like weight-to-insulating ratios unless you`re planning on transporting it deep into the backcountry. If your water bottle will rarely leave your house, state-of-the-art tech that halves the weight and doubles the price doesn`t really offer much utility.
Consider a Quiver
I`m a firm believer in getting gear that pulls double or triple duty, because it`s the best way to lighten up your kit, keep your closets and cabinets uncluttered, and save you money. But for water bottles, I recommend different kinds for different uses. Here`s what`s in my personal rotation: a large 32-to-36-ounce insulated bottle for drinking around the house and stroller running; a smaller 10-to-12-ounce coffee-specific vessel; something really light and uninsulated (like BPA-free plastic) for backpacking, cycling, and ski touring; a handheld for short runs; an
