Perhaps "a doggy bag" would be a better term.
In fact, taking leftovers home from a restaurant is often called a "doggy bag".
The container used for such leftovers is commonly called a "doggy bag" or "doggie bag".
They eat strange food and give out left overs in small doggy bags.
Doggy bags are most common in restaurants that offer a take-out food service as well as sit-down meals, and their prevalence as an accepted social custom varies widely by location.
