Life with My Bottle
Four Benefits
BENEFIT 01
TASTY
Delicious moments, always.
Zojirushi has focused on the functionality of insulated bottles for more than 100 years since its establishment.
While drinks get cold, or are accidentally tipped over and spilled when using mugs or paper cups,
our proprietary double-layer stainless steel vacuum insulation keeps drinks at a delicious temperature*.
There is no need to force yourself to finish the drink. My Bottle can also be sealed so you no longer worry about spilling and getting your desk or bag wet.
Barley tea well chilled with ice in the hot summer and piping hot coffee in the cold winter.
Or as protection against heat stroke when going outside, or warming oneself in a cold office.
My Bottle allows you to enjoy delicious moments anytime, anywhere, and always.
These are the small moments you can only experience once you own a My Bottle.
*Heat retention effect is indicated as the temperature of the contents when boiling water is filled in the product to the position indicated in the instruction manual and left in an upright position for 6 hours at room temperature of 20°C±2°C from the time when the hot water temperature reaches 95°C±1°C.
*Cold retention effect is indicated as the temperature of the contents when cold water is filled in the product to the position indicated in the instruction manual and left in an upright position for 6 hours at room temperature of 20°C±2°C from the time when the water temperature reaches 4°C±1°C.
*Zojirushi’s 480 mL type (Model SM-S) keeps hot water of 95°C±1°C at 71°C or higher even after 6 hours in a room temperature environment of 20°C±2°C. It also has a cold retention effect to keep cold water of 4°C±1°C at 8°C or lower after 6 hours.
Delicious moments also continue ourdoors.
The double-layer stainless steel vacuum bottle provides a restful moment.

BENEFIT 02
HEALTHY
Healthy body, always.
We drink various drinks throughout the day, but may end up drinking too much, and consume too much sugar, caffeine, or additives if we buy a drink each time.
Thinking about health through drinks.
My Bottle is a great tool to support a healthy lifestyle by allowing you to be aware of what and how much you drink every day.
It also allows you to create drinks to your own taste or strength based to your mood and physical condition.
Or help increase your water intake as water is vital to our health playing a key role in many of our body's functions.
You just might want to walk a little longer with My Bottle in your hand.
Let it help you develop a healthy habit of taking daily walks.
How Vacuum Bottles Work
Vacuum bottles can keep contents at a temperature that is just right for drinking.
Learn the secrets of how they keep your drinks at a delicious temperature.
Structure of a Vacuum Bottles (Stainless Steel Bottle Type)
Secret 01: There is a Vacuum Layer
Heat always moves from an area with a higher temperature to one with a lower temperature through materials such as metal, wood, glass, and water (thermal conduction).
Air is also a pathway for heat transfer.
Therefore, heat transfer to the outside can be blocked if the space between the inner bottle and outer bottle of a vacuum bottle is made airless (vacuum).
Secret 02: The Inside of the Bottle is a Mirror
However, there is a type of heat transfer that cannot be prevented by a vacuum alone.
It feels warm when you put your hand over the stove not only because the stove warms the air in the room, but also because the heat from the stove directly hits your hand.
In other words, heat is also transferred by radiation like rays of light (radiant heat).
To prevent this, we create a finish like a mirror by placing a copper or aluminum foil between the inner bottle and outer bottle of the vacuum bottle, so that any heat released outward is reflected back inside by this mirror.
This mechanism keeps the heat trapped inside.
