What is vacuum insulation?
Vacuum means the air between the outer and inner layers of stainless steel has been removed to create a vacuum insulation. It blocks heat from transferring through air.
The vacuum layer does not have to be thick, as the absence of air is what's important and not the amount. Zojirushi's vacuum insulation is as thin as 1mm, keeping the unit compact and lightweight without compromising temperature retention.
How do Zojirushi vacuum mugs and bottles keep drinks hot (or cold)?
Heat loss happens through 3 methods, and Zojirushi vacuum insulated products use the following methods to block them. Drinks stay hot because heat doesn't escape. Drinks stay cold because outside heat can't get in.
1. Vacuum insulation blocks heat from transferring through air
Vacuum insulation prevents heat loss through conduction. Since the air– which is a conductor – is removed between the inner and outer layers of stainless steel, heat isn’t transferred.
2. Aluminum or copper foil reflects heat
A thin sheet of aluminum or copper is wrapped around the outer surface of the inner layer to help reflect radiant heat.
3. Lid blocks heat convection
And finally, heat transfer through convection is blocked by tightly sealing the lids on each of the products. Most lids have their own air insulation to further reduce heat loss.
What is the difference between the various models?
The type of product is defined below. Some are designed to drink directly out of, while others come with a cup to pour into.
Flip-Open Lid Mug
Designed to drink directly through the lid, the flip-open lid makes it easy to take a sip while sealing the drink spout and keeping out dust.
Twist-Off Lid Mug
Designed to drink directly from the cup, the twist-off lid seals tightly and keeps the sip area clean when closed.
Bottle with Cup
Zojirushi bottles come with a one-touch pour through stopper, and a lid that conveniently turns into a cup for drinking.
Designed to drink directly from the cup, Zojirushi tumblers keeps the exterior cool, or condensation free.
Zojirushi cool bottles have a unique drinking spout and are designed for cold beverages only.
Another key feature is the interior finish. There are two types of finishes, SlickSteel® polished stainless steel, and nonstick coated stainless steel.
Our proprietary SlickSteel® is an electrolysis polishing method that makes the 18/8 stainless steel interior highly resistant to corrosion and stains.
Our nonstick surface is a durable coating that resists odor and stains, making cleaning quick and easy. Some models have a double layer of nonstick coating.
