         24 . A container with a pump for discharging bubbles, comprising: 
 a container body having a neck portion; and    a pump for discharging bubbles provided on the neck portion of the container body,    wherein the pump for discharging bubbles comprises:    (a) a cylinder for liquid in which a first piston slides;    (b) a cylinder for air in which a second piston slides;    (c) a pump head on which a nozzle is provided and which is connected to the first piston and the second piston so as to drive the both pistons;    (d) a vapor-liquid mixing chamber in which liquid delivered from the cylinder for liquid and air delivered from the cylinder for air are joined;    (e) a bubbling member provided between the nozzle and the vapor-liquid mixing chamber, and    (f) a mouth piece which is provided on the nozzle of the pump head and whose diameter is reduced into a circular cone cylinder shape as it proceeds forward, and in which the nozzle whose inside diameter is not more than 2.0 mm is opened on the end thereof, and    liquid within the container body and outside air are joined in the vapor-liquid mixing chamber and the joined vapor-liquid is bubbled via the bubbling member to be discharged in a foamy state from the nozzle by depressing the pump head.    
     
     
         25 . A container with a pump for discharging bubbles as claimed in  claim 24 , wherein the bubbling member  34  is formed in a state that a net is stretched over one end opening of short cylinder, and singular or a plurality of bubbling members can be provided in a space between the nozzle and the vapor-liquid mixing chamber in a state that normal or reverse direction can be selected.
