Cup made of paper material and method for the fabrication of a cup

摘要

A cup made of paper material and having a fillable interior including a tubular wall that is at least partially conical, and a bottom wall that is joined to the tubular wall at the bottom end of its interior in a substantially liquid-tight manner. The tubular wall is produced from a plane blank, the end regions of which are joined together in an overlap region. The tubular wall delimits the interior and includes at least one deforming entity extending in the peripheral direction, wherein the peripheral deforming entity is not formed in the overlap region.
