Joghurt-Becher Schutz

This is a protector for yoghurt cups. It fits to 500g "Tip Naturjoghurt" which are sold at the Supermarket "Real" in germany. As my girlfrind hat the problem that the cup bursted from time to time in her bag, leaving a big mess of yoghurt, I made this protector for her :)
It might also fit other 500g yoghurt cups, but no guarantee for this. Maybe I will design some more protectors later...
