How do I keep my drink at the optimum temperature
Many years ago, it was difficult to keep water in a water bottle cold for long, or coffee in a mug hot for long. If you carry a drink around all day, it should be common to find that such a lukewarm drink may cause discomfort. In fact, many bottles and glasses don't keep warm very well. Fortunately, there is a product that can solve this problem, and it is a thermos.
There are many uses for vacuum insulated flasks, but few people know that the vacuum insulated flasks were invented by Sir James Dewar in 1892. At first Sir James Dewar only used the vacuum insulated bottle in scientific experiments to keep the temperature stable, but it was soon used in the home, and about ten years later the vacuum insulated bottle was commercially available.
The construction of a vacuum adiabatic flask is simple. It essentially consists of two containers -- one inside the other, with a vacuum between the walls.
Why does this flask hold heat? The reason is simply that heat is transmitted through contact between two different materials or through the flow of a gas or liquid. Molecular collisions and gas flows are rare or absent in a relative vacuum or in a complete vacuum. There is a vacuum between the walls of the bottle, so the vacuum creates a buffer around the drink, which prevents most of the heat from being transferred through the air. Of course, vacuum-insulated bottles aren't perfect, especially at the mouth, where the two containers meet. But admittedly, it is significantly more effective than uninsulated or single-walled drinks bottles. Good vacuum-insulated water bottles can even stay cold for more than a day!
We novfeel Stainless Steel drinkware company manufacture vacuum insulated water bottles, tumblers, wine sets, coolers and coffee POTS in food grade stainless steel. They are easy to clean, durable and environmentally friendly. They are easy to carry around and fit into car cup holders. Vacuum insulated bottle can withstand heat preservation test, the outer wall can effectively prevent condensation. Wholesalers can find a wide range of vacuum-insulated bottles at novfeel.com, from beer bottles to travel mugs to water bottles.
Keep in mind that cleaning your vacuum-insulated bottle by hand is the best way to do this, as the dishwasher may destroy the vacuum seal. Also, never put it in the refrigerator or microwave. With proper care, you can use it for years and never have to drink tepid drinks again.
