I thought it (more common as "Korobuchka" or "Korobochka") to be a dance tune. The dance description is HERE (without lyrics); score is HERE. MIDI is HERE, and HERE (in the middle of the page as "Oh, Polnim polna moya korobochka"). An index says it is translated as "The Peddler" in English, which I don't have. I've found the Russian and Japanese lyrics HERE (code shift to JIS or other Japanese language system is required to read it; with midi, mp3 (Russian), & score (click just on the right to "mp3")).
