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.

1. A method for the fabrication of a cup made of paper material, comprising the following steps: shaping a planar paper blank into a substantially conical tubular wall and joining end regions of said blank to each other in an overlap region, inserting a pot-type bottom wall into said conical tubular wall so that a peripheral portion of said bottom wall rests against an interior surface of said conical tubular wall, and forming a deforming entity in one piece with said conical tubular wall and from the same paper material as said conical tubular wall so as to extend peripherally around said conical tubular wall except in said overlap region, said peripheral deforming entity forming a part of a finished cup.
