摘要

Hollow body comprises a triangular cross-section (108) which changes size along the annular periphery and has a concave surface (109), a convex surface (110) and a planar surface (111). The concave and convex surfaces have a common edge and form a triangular cross-section via the planar surface. Preferred Features: The material of one side is made from cardboard, plastic film, wood or sheet metal.
