Zojirushi Announces New Compact Stainless Food Jar Featuring a "ThermoRing Structure" and "Seamless Lid"
We are proud to announce the launch of the new Compact Stainless Food Jar SW-NA20. Part of our popular “Seamless Lid” series, SW-NA20 is designed specifically for those who want to add a small side, like instant soup, to their daily lunch box without carrying a bulky container, this 200mL (0.2L) food jar delivers unparalleled portability and functionality.
SW-NA20 combines Zojirushi's renowned double-wall vacuum insulation with an innovative "ThermoRing structure" to maintain the perfect eating temperature for hours. Additionally, the signature "Seamless Lid" design integrates the stopper and gasket into a single piece, making daily cleaning easier than ever.
Key Features
- Amazing Heat & Cold Retention:
Double-wall stainless steel vacuum insulation paired with the new "ThermoRing structure" minimizes heat loss from the opening. It keeps your meal at the ideal temperature (above 62°C or below 10°C) for up to 6 hours.

- Seamless Lid (Integrated Gasket and Stopper):
Combines the gasket and stopper into one single piece to eliminate hassle, prevent lost parts, and simplify daily cleaning.

- All Parts Dishwasher Safe:
Every part can be cleaned in a dishwasher for maximum convenience.
- Slick Steel Plus Interior:
The interior features a highly corrosion-resistant and rust-proof finish that repels stains, ensuring it remains clean with minimal effort.
- Smooth & Wide Opening:
Designed with a rounded and smooth edge for a pleasant sipping experience, and a wide 5 cm opening that makes it easy to pour soup and eat directly from the jar.
