Receptacle for leftover food (5,3)

I believe the answer is:

doggy bag

(Other definitions for doggy bag that I've seen before include "Container for still-wanted meal leftovers" , "Party leftover container" , "Leftover food carrier" , "In which to take restaurant leftovers home" , "Container for what you can't eat when dining out" .)

I've seen this clue in The Guardian.
