Function
As you may already know, Zojirushi started with the manufacturing of vacuum insulated products.
Based on vacuum insulation technology, we have since produced various kitchen, living and commercial products.
Manufactured a tabletop carafe, the "Pelican Pot", which was to become the basis of Zojirushi vacuum insulation products. The model changed from the portable bottle type to the tabletop carafe type. It became one of our longtime hit products. Beverage bottle developed into insulated containers that hold foods, in the shape of lunch jars and food jars. At present, we are manufacturing different kinds of products to fit the diverse needs of our customers.

Designed to match any occasion
Food Jars are designed to hold food and eaten right out of the jar. Ideal not only for soups, but desserts or porridges as well. Wide opening makes it easy to eat, and easy to clean. By taking advantage of high temperature retention technology, food can actually be cooked while being stored by using the food’s own heated temperature--and some easy preparation before leaving the house. Mini Bentos come with a main bowl that fits into an insulated container, and two non-insulated side bowls. They all fit in a matching tote bag and comes with chopsticks. These lunch kits are smaller than the Lunch Jars, and are especially ideal for kids to take to school. Lunch Jars consist of three or four inner bowls that all fit into one container. One or two containers hold a main entrée or soup, and sit at the bottom of the vacuum insulated outer container to stay hot or cold. They also come with one or two side bowls that are stacked on top, and stay at room temperature.

Containers designed for foods

Food Jars have an electro-polished SlickSteel® finish, while lunch jars are nonstick coated.

SlickSteel® Finish:
Food Jars have the SlickSteel® interior, an electrolysis polished finish which gives the stainless steel similar properties to a nonstick finish, but without the coating.
Nonstick Coating:
Lunch Jars’ outer container is nonstick coated, which resists odors and stains, and makes it easy to clean. Food is not designed to be placed directly in the outer container.
Food Jars are like vacuum insulated mugs. The entire body retains hot or cold temperature, as shown. Lunch Jars consists of a hot or cold temperature section and a room temperature section, as shown.

Designed for more ease of use
The lid may become difficult to open from the inner pressure caused by filling with hot food. This pressure can be released by a built-in vent in the middle of the lid. The soup bowl lid may become difficult to open from the inner pressure caused by filling with hot food. This pressure can be released by a built-in vent in the middle of the lid.
Lid disassembles for thorough cleaning. Extra wide opening makes it easy to fill, easy to eat. The main bowl's lid is insulated, allowing for better heat retention, while also blocking the heat from transferring to foods in the side bowl. Multiple bowls allow complete separation of foods.

Colors and bags that express yourself
Zojirushi is committed to staying with current color trends for our products.
We regard our jars as fashion accessories as well as insulation equipment.
Tote Bags for Food Jars. Very simple in concept, but designed to make it easy to use, and allows you to take extra food, like bread, fruit, or drinks. Matching Mini Bento Lunch Jars. The bright colors are emphasized by using the same color and pattern as on bags. Red and Yellow Jars. These two colors are sold only in the USA. We took care to produce beautiful colors without losing the stainless texture.
line
Lightweight and compact
Zojirushi continuously strives to design Food Jars and Lunch Jars that are lighter and more compact by utilizing new technology that allows for minimal use of materials, and creating a vacuum insulation layer that is about 1mm in thickness without compromising heat retention properties.

Lunch Jars and Food Jars are optimized for lightweight and compact design, easily carried inside a tote bag or your bag.

What is vacuum insulation?
Vacuum insulation provides the best heat retention. Vacuum means the air between the outer and inner layers of the stainless steel has been removed to create a vacuum insulation. It blocks heat from transferring through air which greatly minimizes the temperature change of your food.

What is heat retention?
Heat retention is the amount of heat an object can maintain for a period of time. A vacuum insulated
stainless food jar and lunch jar can maintain the temperature much longer than a non-insulated container.
On the left is Heat Retention. Hot soup or food packed at 6am in the morning will still be hot at lunch. On the right is Cold Retention. Cold desserts or food packed at 6am in the morning will still be pretty cold at lunch.

For people who have trouble choosing the perfect Food Jar or Lunch Jar for themselves,
we would like to suggest error-free tips on what to look for.

1
Choose by type:
Food Jars are perfect for packing a single item such as a soup or entrée. Because food is placed directly inside, it also has better heat retention than Lunch Jars. Lunch Jars have multiple bowls for various uses and can pack an entire meal.

2
Choose by size:
Choose the product that fits the size of your portion. Capacity is listed by its entire capacity. A 17 oz. Food Jar would hold 17 oz. of soup. A Lunch Jar may hold soup, entrée and sides, for a total of 50 oz. of food.line
3
Choose by color:
From traditional black to pop colors, there are many to choose from. Certain models come with matching bags. Choose the color that catches your fancy.
