Abstract
A cup made of a paper material and having a fillable interior formed by a conical tubular wall and a bottom wall is provided. The bottom wall is joined at a bottom end of the interior to a peripheral edge frame of the tubular wall in a substantially liquid-tight manner. The tubular wall has a peripheral deforming entity around at least part of a perimeter, which peripheral deforming entity is reinforced in order to avoid deformation of the paper cup.
