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.

A cup of a paper material comprising a fillable interior formed by an at least partially conical and interior delimiting tubular wall and a bottom wall, the bottom wall being joined to the tubular wall in a region of a bottom end of the interior in a substantially liquid-tight manner, wherein the
1. A cup of a paper material comprising a fillable interior formed by an at least partially conical and interior delimiting tubular wall and a bottom wall, the bottom wall being joined to the tubular wall in a region of a bottom end of the interior in a substantially liquid-tight manner, wherein the tubular wall comprises at least one peripheral deforming entity disposed adjacent the bottom wall, the peripheral deforming entity including a groove formed in the tubular wall and a rib which projects inwardly into the interior, a top of the rib having a cup-supporting surface disposed to support a cup of the same type in a vertical stack of a plurality of the cups, the groove opening outwardly immediately adjacent and opposite the rib, and a reinforcement attached to the cup and disposed in the groove for stabilizing the rib. 2. The cup according to claim 1, wherein the reinforcement is in the form of a coating applied to the tubular wall. 3. The cup according to claim 1, wherein the reinforcement is in the form of an adhesive fillet applied to the tubular wall. 4. The cup according to claim 3, wherein the adhesive fillet is applied over an entire periphery of the tubular wall within the groove for stabilizing the rib. 5. The cup according to claim 1, wherein the cup has an outer sleeve at least partially surrounding the tubular wall, and the cup-supporting surface is disposed to support the outer sleeve of a cup of the same type in a vertical stack of a plurality of the cups. 6. The cup according to claim 1, wherein the rib forms an at least partial cross-sectional constriction of the interior of the cup, as viewed from an open end of the cup toward the bottom wall, the reinforcement being disposed directly downstream of the cross-sectional constriction. 7. The cup according to claim 6, wherein the reinforcement is disposed against and in contact with the tubular wall on an external surface thereof and in the groove remote from the interior of the cup in that region thereof in which the rib forms the cross-sectional constriction. 8. The cup according to claim 1, wherein the reinforcement is fixed to the tubular wall within the groove of the peripheral deforming entity. 9. The cup according to claim 1, wherein the cup-supporting surface is disposed closer to the bottom end of the interior than to a top end of the interior of the cup. 10. A method for producing a cup of paper material, the method comprising the steps of: joining a conical tubular wall to a bottom wall of the cup in a substantially liquid-tight manner, incorporating at least one peripheral deforming entity in the tubular wall adjacent the bottom wall such that the peripheral deforming entity includes a groove formed in the tubular wall and a rib projecting inwardly into an interior of the cup, a top of the rib having a cup-supporting surface disposed to support a cup of the same type in a vertical stack of a plurality of the cups, and such that the groove of the peripheral deforming entity opens outwardly immediately adjacent and opposite the rib, and providing a reinforcement attached to the cup and disposed in the groove of the peripheral deforming entity for stabilizing the rib. 11. The method according to claim 10, including providing the reinforcement on an exterior surface of the tubular wall remote from the interior of the cup. 12. A method according to claim 10, wherein the step of providing the reinforcement includes providing an adhesive fillet in the groove of the peripheral deforming entity for stabilizing the rib. 13. The method according to claim 10, wherein the step of providing the reinforcement includes fixing the reinforcement to the tubular wall within the groove. 14. The method according to claim 10, wherein the step of incorporating the peripheral deforming entity includes providing the peripheral deforming entity closer to the bottom wall than to a top end of the cup. 15. A cup of a paper material comprising: a fillable interior formed by an at least partially conical and interior delimiting tubular wall and a bottom wall, the bottom wall and the tubular wall being joined to one another in a region of a bottom end of the interior in a substantially liquid-tight manner in the form of a liquid-tight joint, the bottom wall and the tubular wall forming a peripheral edge frame in a region of the liquid-tight joint, the tubular wall comprising at least one peripheral deforming entity, the peripheral deforming entity being disposed to support a peripheral edge frame of a cup of the same type in a stack comprising a plurality of the cups; anda reinforcement for stabilizing the peripheral deforming entity, the reinforcement being in a region of the peripheral deforming entity and being in the form of an adhesive fillet applied to the tubular wall for stabilizing the peripheral deforming entity over the entire periphery of the tubular wall, wherein the peripheral deforming entity forms an at least partial cross-sectional constriction of the interior of the cup, as viewed from an open end of the cup toward the bottom wall, and defines a recess in the tubular wall which opens outwardly, the adhesive-fillet being disposed directly downstream of the cross-sectional constriction, and the adhesive fillet is disposed against the tubular wall and within the recess thereof on an external surface of the tubular wall remote from the interior of the cup in a region thereof in which the peripheral deforming entity forms the cross-sectional constriction. 16. A cup of paper material having a central longitudinal axis, said cup comprising: a tubular wall having oppositely facing interior and exterior surfaces and having a conical configuration along a portion of said tubular wall, said tubular wall being deformed inwardly towards the cup axis so as to define a shoulder having a cup-supporting surface located interiorly of said cup along said interior surface of said tubular wall, said shoulder defining an inwardly-projecting cavity at said exterior surface of said tubular wall opposite and immediately adjacent said cup-supporting surface;a bottom wall joined to said tubular wall adjacent a bottom region thereof in a substantially liquid-tight manner, said cup-supporting surface of said shoulder being disposed closer to said bottom wall than to a top region of said tubular wall, being oriented substantially parallel to said bottom wall, and facing away from said bottom wall for supporting a cup in a vertical stack of a plurality of said cups; anda reinforcement attached to and in contact with said exterior surface of said tubular wall within said cavity for stabilizing said shoulder. 17. The cup according to claim 16, wherein said reinforcement is fixed to said exterior surface of said tubular wall within said cavity. 18. The cup according to claim 16, wherein said cup-supporting surface projects towards the cup axis inwardly beyond a portion of said interior surface of said tubular wall disposed between said cup-supporting surface and said top region of said tubular wall. 19. The cup according to claim 16, wherein said reinforcement has a shape which conforms to a shape of said cavity and is in direct contact with said exterior surface of said tubular wall.
