         9 . A cup, the cup having a cup body and a cup opening, the cup opening having a cup rim; wherein:
 the cup opening has a front side, a rear side, a left area and a right area, and the left area and the right area are respectively located between the front side and the rear side;   at least the front, the left area and the right area cup rims of the cup opening are everted cup rims, the front cup rim has a front everted angle; the left area cup rim has at least one left area everted angle; the right area cup rim has at least one right area everted angle; the front everted angle, the at least one left area everted angle and the at least one right area everted angle form at least two different angles.   
     
     
         10 . The cup as claimed in  claim 9 , wherein the rear cup rim of the cup opening has a rear everted angle, and the rear everted angle is the smallest everted angle of the cup opening. 
     
     
         11 . The cup as claimed in  claim 10 , wherein the front everted angle is the largest everted angle; angle values of the at least one left area everted angle and the at least one right area everted angle are between that of the front everted angle and the rear everted angle. 
     
     
         12 . The cup as claimed in  claim 9 , wherein the left area of the cup opening comprises: a left front side, a left side and a left rear side of the cup opening; the right area of the cup opening comprises: a right front side, a right side and a right rear side of the cup opening; the at least one left area everted angle comprises any one of or all of everted angles formed by the cup rim at the left front side, the left side and the left rear side; the at least one right area everted angle comprises any one of or all of everted angles formed by the cup rim at the right front side, the right side and the right rear side. 
     
     
         13 . The cup as claimed in  claim 12 , wherein angle values of everted angles of the cup rim at the left front side, the left side and the left rear side change continuously; angle values of everted angles of the cup rim at the right front side, the right side and the right rear side change continuously. 
     
     
         14 . The cup as claimed in  claim 9 , wherein a longitudinal direction is provided from the cup opening of the cup to a bottom of the cup, based on the longitudinal direction, an everted angle of the front cup rim ranges from 30˜70 degrees; an everted angle of the left area cup rim ranges from 5˜70 degrees; an everted angle of the right area cup rim ranges from 5˜70 degrees.
