Claim:
A container with a pump for discharging bubbles, comprising: a container body having a neck portion; and a pump for discharging said bubbles provided on the neck portion of the container body, wherein the pump for discharging said bubbles comprises: (a) a first cylinder for delivering liquid within the container body, and a first piston that slides in the first cylinder; (b) a second cylinder for delivering outside air, and a second piston that slides in the second cylinder; (c) a pump head on which a nozzle is provided, the pump head being connected to the first piston and the second piston so as to drive the both pistons; (d) a vapor-liquid mixing chamber in which the liquid delivered from the first cylinder and the outside air delivered from the second cylinder are joined; and (e) a bubbling member provided between the nozzle and the vapor-liquid mixing chamber; joined vapor-liquid is made from the liquid within the container body and the outside air 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; and a nozzle attachment which switches between a first opening and a second opening for discharging said bubbles is provided on the nozzle of the pump head, a size of the second opening being smaller than that of the first opening, the nozzle attachment including a discharging hole having a diameter, the diameter of the discharging hole changing from a first point connected to the first opening at which the joined-vapor liquid first enters the discharging hole to a second point at which the second opening is arranged and the joined-vapor liquid exits the discharging hole.
