The Zojirushi Stainless Steel Food Jar is a good option if you need to carry foods instead of just beverages, as it features a wide neck for easy access. This high-tier thermos does lack features but offers a reasonable capacity.
With a double-walled 18/8 stainless steel construction, the Zojirushi food jar provides vacuum insulation that keeps the contents warm or cool for up to six hours. The interior has an electro-polished stainless steel finish that helps to repel stains and resist corrosion. However, it is not scratch resistant, so it requires gentle cleaning and the unit is not dishwasher safe. The thermos measures 4 x 7.25 inches and weighs 0.14 pounds when empty, so is reasonably compact. It has a maximum capacity of 25 ounces, which isn't outstanding, particularly given the price point.
The wide neck of this thermos allows you easy access to scoop or pour food and beverages out and makes cleaning fast and simple. For a tight fit and to minimize the risk of leaks or spills, this model uses a threaded gasket seal. However, as it isn't completely airtight, it is advisable to keep it standing upright during transport. You need to leave at least a half-inch below the ridge, or the travel tumbler could overflow when you screw on the lid. It cannot handle carbonated drinks and is not safe for fruit juices and raw foods, so it is of limited use.
The manufacturer states that foods with strong odors or colors must be placed in a food-safe bag to avoid stains and odors lingering in the thermos. It also states that you cannot put raw or cold dairy into the food jar without thoroughly heating them first, to reduce the risk of spoilage.
Around the lid, there are indentations at regular intervals, making opening the travel tumbler easier. The lid has a polypropylene and silicon construction for corrosion resistance and durability. Although it only retains temperature for six hours, it is a convenient option for keeping baby food warm, particularly if you're taking a long trip or planning to stop where there are no facilities.
The Zojirushi Stainless Steel Food Jar is of limited use. While it offers a wide neck so you can store food and drink, there are a whole range of restrictions about what you can store in it and how you store things in it. Additionally, the lid isn't airtight, so leaks occur unless you keep it upright.
