What do you call this - nestled containers

[SaltyNuts]

What do you call it where you want one container that sits within another, but just a little bit smaller? I'm basically looking for clear plastic or glass containers, don't care about the shape too much (square, rounded, etc.), but where one will fit inside the other but its kind of a close fit. Is there a particular word or verbiage that describes this so I can search for them?

Thanks for any help.

Nested food storage containers seems to work.
