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.

What is claimed is: 1. 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. 2. A container with a pump for discharging bubbles according to claim 1, wherein the nozzle attachment comprise: a cylinder body portion provided on the nozzle including the first opening; and a closing body which has the second opening and is provided on a first opening side of the cylinder body portion via a hinge such that the closing body is capable of being swung to open and close the first opening. 3. A container with a pump for discharging bubbles according to claim 1, wherein the diameter of the discharging hole is larger at the first point than the second point. 4. 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; (e) a bubbling member provided between the nozzle and the vapor-liquid mixing chamber; (f) a mouth piece which is provided on the nozzle of the pump head and has a circular cone cylinder shape having an opening for discharging said bubbles at a top thereof, a diameter of the opening being not more than 2.0 mm and being different than a diameter of a bottom face of the mouth piece, the mouth piece including a discharging hole having a diameter, the diameter of the discharging hole changing from a first point at which the bottom face is arranged and the joined-vapor liquid first enters the discharging hole to a second point at which the opening is arranged and the joined-vapor liquid exits the discharging hole, and 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. 5. A container with a pump for discharging bubbles as claimed in claim 4, wherein the bubbling member 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. 6. A container with a pump for discharging bubbles according to claim 4, wherein the diameter of the discharging hole is larger at the first point than the second point. 7. 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, wherein the nozzle attachment comprises: a cylinder body portion that functions as a bubble passage and has the first opening; a closing body provided at a distal end of the cylinder body portion, the closing body being fitted into the first opening of the cylinder body portion; and a discharging nozzle provided on the closing body, wherein the discharging nozzle tapers away from the closing body and has the second opening at a top thereof. 8. A container with a pump for discharging bubbles according to claim 7, wherein the cylinder body portion has a rectangular cross-section. 9. A container with a pump for discharging bubbles according to claim 7, wherein the foam discharged from the nozzle contains finer bubbles and is discharged more strongly when the closing body is fitted into the cylinder body portion.
