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 cup made of paper material and having a fillable interior, which is formed by means of an at least partially conical tubular wall and a bottom wall, wherein said bottom wall is joined to said tubular wall in the region of a bottom end of said interior in a substantially liquid-tight manner, wherein said tubular wall is formed from a plane blank of paper material, whose end regions are bonded to each other in an overlap region, and wherein said tubular wall delimiting said interior comprises at least one deforming entity extending in the peripheral direction and forming part of a finished said cup, said peripheral deforming entity being formed in one piece with the tubular wall from the same paper material as the tubular wall, and said peripheral deforming entity is not formed in said overlap region. 2. The cup as defined in claim 1, wherein said peripheral deforming entity extends along the entire periphery of said tubular wall with the exception of said overlap region. 3. The cup as defined in claim 1, wherein said peripheral deforming entity forms a bend or curve in the vicinity of said overlap region, wherein said peripheral deforming entity, as seen in the direction toward said overlap region, extends on both sides of said overlap region forming a bend or curve directed toward said bottom wall of said cup. 4. The cup as defined in claim 3, wherein said peripheral deforming entity deviates, in the vicinity of said overlap region, from a straight course in the peripheral direction to a bend through an angle of 90 degrees directed toward said bottom wall. 5. The cup as defined in claim 3, wherein said peripheral deforming entity bends to form an arc of a circle. 6. The cup as defined in claim 1, wherein the radial depth of said peripheral deforming entity diminishes in the direction toward said overlap region. 7. The cup as defined in claim 6, wherein said depth of said peripheral deforming entity diminishes down to zero. 8. The cup as defined in claim 1, wherein the inside diameter of said tubular wall at the level of said peripheral deforming entity is smaller than the inside diameter of said tubular wall at the level of said bottom wall. 9. The cup as defined in claim 1, wherein said overlap region extends substantially longitudinally along said tubular wall in a direction transverse to top and bottom edges of said cup. 10. The cup as defined in claim 9, wherein said peripheral deforming entity comprises a deformed portion of said tubular wall, said deformed portion comprising a shoulder formed within said interior of said cup and having a cup-stacking surface formed on an interior surface of said tubular wall, said cup-stacking surface facing away from said bottom wall for supporting a cup in a vertical stack of a plurality of said cups. 11. The cup as defined in claim 9, wherein both said tubular wall and said bottom wall are constructed of paper material. 12. The cup as defined in claim 1, wherein said overlap region extends substantially longitudinally along said tubular wall in a direction transverse to top and bottom edges of said cup, both said tubular wall and said bottom wall are constructed of paper material, and said deforming entity comprises a deformed portion of said tubular wall, said deformed portion comprising a shoulder formed within said interior of said cup and having a cup-stacking surface formed on an interior surface of said tubular wall, said cup-stacking surface facing away from said bottom wall for supporting a cup in a vertical stack of a plurality of said cups. 13. A cup made of paper material having a central longitudinal axis, said cup comprising: a tubular wall of paper material and having oppositely facing interior and exterior surfaces and having an at least partially conical configuration, said tubular wall being formed from a planar blank and having a pair of end regions which overlap one another to define an overlapping region which extends substantially in the direction of said cup axis, said end regions being bonded to one another in said overlapping region, said tubular wall being deformed inwardly so as to define a cup-stacking shoulder of paper material formed in one piece with said tubular wall, said cup-stacking shoulder being located interiorly of said cup along said interior surface of said tubular wall and forming part of a finished said cup, said cup-stacking shoulder extending peripherally about the cup axis but being discontinued at said overlapping region; anda bottom wall of paper material joined to said tubular wall, said interior of said tubular wall and said bottom wall together defining a fillable interior, said bottom wall being joined to said tubular wall in a substantially liquid-tight manner adjacent a bottom end of said interior, and said cup-stacking shoulder being disposed adjacent said bottom wall. 14. The cup as defined in claim 13, wherein said cup-stacking shoulder extends along an entire periphery of said interior surface of said tubular wall except in said overlapping region. 15. The cup as defined in claim 13, wherein said cup-stacking shoulder has a surface oriented transversely relative to the cup axis and facing away from said bottom wall for supporting a cup in a vertical stack of a plurality of said cups.
