I pack a lunchbox every morning. I don’t like cooking very much, so I want to buy a new lunchbox to cheer up my motivation to pack lunchboxes. I was looking for a new lunchbox on Amazon.co.jp and it recommended me to buy a vacuum flask for soup. It is called a ‘magic jar(*)’ in Japanese. Vacuum flasks don’t need any energy, but they keep the temperature you contain something into them for a while. That’s why it is called a “magic jar” in Japanese. However, it is also called “Thermos” because Thermos is one of the most popular vacuum flask companies. It is like Xerox.
I bought a food jar like this:http://www.google.co.jp/search?tbm=isch&hl=ja&source=hp&biw=1215&bih=660&q=JBI-270&gbv=2&oq=JBI-270&aq=f&aqi=g-S6g-mS1&aql=&gs_l=img.12..0i24l6j0i5i24.1387l1387l0l2541l1l1l0l0l0l0l20l20l1l1l0.frgbld.
I make soup for breakfast and leave some for my lunch. I make minestrone or miso soup. When I eat soup at noon, it isn’t very hot, but it is still warm to eat. I am satisfied with this food jar.
The picture is a lunch one day.
