Does a container that works like a thermos but shaped like a tupperware exist?

It sounds like you are talking about a bento box. This is how I pack my lunch every day! This is very close to the one that I have. For food safety, it is a good idea to check this out before you pack

I’ve got something like this at home, it keeps my food nice and warm, so I assume it would keep things cold too?; search for ”Thermos Jar” and there are some different options.

@Kayak8 Thanks, that looks similar.

@DancingMind thanks. That is a thermos though. I’m thinking a tupperware, with different compartments for salad etc. but with qualities of a thermos.

Oh no problem : )
I don’t have compartmented tupperware… didn’t know it existed!

There’s always a desktop sized personal fridge that holds 6 cans of soft drinks, or the equivalent of other stuff…

Tupperware would probably not retain the cold. However, maybe you have a product idea, providing there’s a market for it.

What you will probably find is an insulated lunch or casserole carrier that would hold a compartmentalized container.

Here is another version of obento . . .

@BarnacleBill The fridge, although it is nice to know about, I want to take my luch everyday in and not have to take it out until I am ready to eat.

@Kayak8 it doesn’t say anything about thermos qualities though.

You could just insulate a box.

I’ve had several good insulated bags or containers from Walmart or Zellers at very reasonable prices. And I’ve added freezer packs to containers to make things stay cool longer.

They sell insulated lunchboxes with those fake ice pack things. I find it easier just to make a no-mayo sandwich and toss it and some chips and an apple into a brown sack.

You can fill a glass bottle (such as a clean, empty Snapple one) ¾ full of water, and place in freezer overnight.

Then include it in your insulated bag with sandwich. The ice will melt slowly and give you a beverage as a bonus. You can add a little tea or juice to the water or fresh mint to make it interesting.

@incendiary_dan, @faye, @Nullo, @gailcalled,
Thank you all.

There probably are other purposes for it though.
