         2 . A closure capsule for closing a container, comprising: a lateral portion ( 2 ) having a substantially cylindrical shape; a transversal wall ( 3 ), connected to an end of the lateral portion ( 2 ); a first seal lip ( 4 ), having a substantially cylindrical shape, concentric to the lateral portion ( 2 ) and projecting below the transversal wall ( 3 ); a plurality of grooves ( 7 ) fashioned on an internal face of the lateral portion ( 2 ) and arranged parallel to a central axis of the lateral portion ( 2 ); characterised in that it comprises a plurality of ribs ( 8 ) arranged within the grooves ( 7 ) transversally to the central axis of the lateral portion ( 2 ). 
     
     
         3 . The capsule according to  claim 2 , wherein the lateral portion ( 2 ) comprises an internal thread which is interrupted at each groove ( 7 ), wherein the ribs ( 8 ) are aligned with the internal thread. 
     
     
         4 . A closure capsule for closing a container, comprising: a lateral portion ( 2 ), having a substantially cylindrical shape; a transversal wall ( 3 ), connected to an end of the lateral portion ( 2 ); characterised in that it comprises a cup-shaped seal element ( 12 ), associated to the transversal wall ( 3 ) and projecting below the transversal wall ( 3 ) concentrically to the lateral portion ( 2 ), the seal element ( 12 ) being made of a gas-impermeable material. 
     
     
         5 . The capsule according to  claim 4 , wherein the seal element ( 12 ) is alternatively made of: polypropylene, polyethylene, PET, PBT, PEF, PLA, PEE. 
     
     
         6 . The capsule according to  claim 4 , wherein the seal element ( 12 ) is realised by compression or by injection. 
     
     
         7 . The capsule according to  claim 4 , wherein the seal element ( 12 ) comprises a circular rib ( 13 ). 
     
     
         8 . A closure capsule for bottles or containers, comprising: a lateral portion ( 2 ), having a cylindrical shape and a longitudinal axis (X); a transversal wall ( 3 ), associated to an end of the lateral portion ( 2 ) at a junction zone ( 4 ); a plurality of ribs ( 5 ), which project externally from the surface of the lateral portion ( 2 ) and are orientated parallel to the longitudinal axis (X); characterised in that the ribs ( 5 ) also extend to the junction zone ( 4 ). 
     
     
         9 . The capsule according to  claim 8 , wherein the ribs ( 5 ) extend over the entire thickness of the transversal wall ( 3 ). 
     
     
         10 . The capsule according to  claim 8 , wherein the transversal wall ( 3 ) is substantially tangential to an end plane (T) perpendicular to the longitudinal axis (X), and wherein the ribs ( 5 ), at an end thereof, are tangential to the end plane (T). 
     
     
         11 . The capsule according to  claim 8 , comprising a seal gasket ( 6 ), applied to the transversal wall ( 3 ) within of the lateral portion ( 2 ). 
     
     
         12 . The capsule according to  claim 11 , wherein the seal gasket ( 6 ) has a projecting seal lip ( 61 ).
