Abstract
A pump for discharging bubbles is provided on a neck portion of a container body. The pump for discharging bubbles comprises a cylinder for liquid in which a first piston slides, a cylinder for air in which a second piston slides, 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, a vapor-liquid mixing chamber in which liquid delivered from the cylinder for liquid and air delivered from the cylinder for air are joined and a bubbling member provided between the nozzle and the vapor-liquid mixing chamber. Liquid within the container body and outside air are pumped up to be joined in the vapor-liquid mixing chamber and the vapor-liquid is bubbled via the bubbling member to be discharged in a foamy state from the nozzle by depressing the pump head.
