A cup made of a paper material having a fillable interior, which cup is formed by a conical sleeve and a bottom. The bottom is attached to the sleeve at the lower end of the interior with a bottom skirt in an essentially liquid-tight way. The sleeve and/or the bottom in the area of the bottom skirt and/or the bottom skirt itself comprises, at least in one area along the periphery, an outwardly projecting widening. A lower edge of the widening forms a standing surface for the cup. The widening can serve to hold another cup of the same type, and can act together with a similar cup during stacking. The cup can include a heat insulating outer sleeve.
