In most Indian languages, dabba typically means box or tiffin box. In colloquial usage, it refers to food that is carried from home to school or work, to be eaten after a few hours at lunch time. The dabba is usually some kind of air-tight container that does not dry up or leak the contents and keeps it relatively fresh.
