Klingedings, mixerbums, container, lid and lid with opening - it's been a while, I think that was in there...

5 pieces is completely exaggerated: Blender, container, blade and drinking attachment. Perhaps the operation should be rated as a 5th part. Finally, a blender and you're done!

Right, the blender (1), the grinding blade (2), a container (3), a cup attachment (4) and a drinking ring (5)
I hope my answer has helped you
best regards
