         2 . A vacuum-sealed container of  claim 1  wherein; an intake hole  24  is formed on the container cover  20 , and an intake valve  60  is provided on the intake hole  24  to inflow outer air into the sealed inner space of the container body  10 . 
     
     
         3 . A vacuumed-sealed container of  claim 1  wherein;
 a upper disc  36   a  and a lower disc  36   b  spaced from the upper disc  36   a  are formed on the lower end of the elevating bar  36 , and the ventilation channel  38  is formed on the surface of the elevating bar  36 , the upper end of the ventilation channel  38  extending through the upper disc  36   a  and the lower end of the ventilation channel  38  extending to stop above of the lower disc  36   b,  the second check valve  50  is formed of ring shape to be inserted between the upper disc  36   a  and the lower disc  36   b,  and the thickness t of the second check valve  50  is thinner than the distance d between the upper and lower disc  36   a,    36   b  as well as the distance d 1  between the lower end of the upper disc  36   a  and the lower end of the ventilation channel  38 , so that if the elevating bar  36  moves downward, the second check valve  50  contacts the upper disc  36   a  and the ventilation channel  38  is opened, and if the elevating bar  36  moves upward, the second check valve  50  contacts the lower disc  36   b  and the ventilation channel  38  is closed. 
 
     
     
         4 . A vacuumed-sealed container of  claim 1  wherein; a recess  21  is formed on the upper surface of the container cover  20 , and the hinge portions  22  being disposed on the opposed walls of the recess  21 , the rotating cylinders  31 of the handle  30  is formed of L shape, and first ends of the rotating cylinders  31  is coupled to the hinge portions  22  rotatably, and second ends of the rotating cylinders  31  is coupled to the elevating bar  36  of the handle  36  movably upward/downward, and the handle  30  can be rotated to be inserted in the recess  21 . 
     
     
         5 . A vacuumed-sealed container of  claim 2  wherein; a upper disc  36   a  and a lower disc  36   b  spaced from the upper disc  36   a  are formed on the lower end of the elevating bar  36 , and the ventilation channel  38  is formed on the surface of the elevating bar  36 , the upper end of the ventilation channel  38  extending through the upper disc  36   a  and the lower end of the ventilation channel  38  extending to stop above of the lower disc  36   b,  the second check valve  50  is formed of ring shape to be inserted between the upper disc  36   a  and the lower disc  36   b,  and the thickness t of the second check valve  50  is thinner than the distance d between the upper and lower disc  36   a,    36   b  as well as the distance d 1  between the lower end of the upper disc  36   a  and the lower end of the ventilation channel  38 , so that if the elevating bar  36  moves downward, the second check valve  50  contacts the upper disc  36   a  and the ventilation channel  38  is opened, and if the elevating bar  36  moves upward, the second check valve  50  contacts the lower disc  36   b  and the ventilation channel  38  is closed. 
     
     
         6 . A vacuumed-sealed container of  claim 2  wherein; a recess  21  is formed on the upper surface of the container cover  20 , and the hinge portions  22  being disposed on the opposed walls of the recess  21 , the rotating cylinders  31  of the handle  30  is formed of L shape, and first ends of the rotating cylinders  31  is coupled to the hinge portions  22  rotatably, and second ends of the rotating cylinders  31  is coupled to the elevating bar  36  of the handle  36  movably upward/downward, and the handle  30  can be rotated to be inserted in the recess  21 .
