The amazing technology behind a Zojirishu vacuum bottle
Vacuum bottles have insulating properties that enable the inside liquid to retain its ideal temperature for a long time. This means your coffee will stay hot while your fingers and toes freeze, and your water will be cool while you sweat it out in the heat.
Zojirishu uses the law of thermodynamics and heat transfer to keep your drinks at the right temperature. Put simply, the lid of the bottle acts as a vacuum and traps the air inside from entering or leaving, and the insulation surrounding the inside of the bottle prevents heat from moving. This is known as conduction and radiation and it works to keep hot things hot, and cold things cold.
Why you need a vacuum bottle
There are some instances where you may not be able to reheat or refrigerate your drink while you are outdoors or indoors. A vacuum bottle enables you to keep your liquids cool for up to 24 hours or keep it warm for up to 8 hours for your convenience. If you're fishing or hunting with friends, a vacuum bottle is a great utensil to have next to you while you are waiting. Even if you're not the outdoorsy type, you'll still be able to benefit from a Zojirishu vacuum bottle. Keep on your desk or under the counter while you're at work, and you'll be able to comfortably sip away without having to go anywhere. Having a vacuum bottle nearby also means you won't need to spend money on coffee or drinks - you can simply fill up your flask before you leave your home, and then use it all day long. A Zojirishu also doubles as a great collectable bottle.
