OMNI...
Efrem we also get Tomato Sauce (Ketchup) in those little containers. Most places around Australia that sell pies (little single person pastry pies with usually plain meat in them - nothing like it in the US, closest thing probebly those hot pot things) sell their tomato sauce like that. It's a convenient way to sell individual portions and, like you said, the contents are more likely to go where they need.
