PROBLEM TO BE SOLVED: To provide a bubble discharge device which discharges a liquid in a container body A and outside air as bubbles by mixing and foaming them, which can miniaturize the container body by reducing a dead space in the container body, which can reduce the amount of molding resin by simplifying a structure, and which can be wholly slimmed down.SOLUTION: A foamer pump B includes: a cylinder member B1 which comprises a large-diameter air cylinder 21 attached to a container body by fitting an attachment cylinder 20 into an outer periphery of a mouth and neck part 12, continuously provided on the attachment cylinder and positioned on the mouth and neck part, and a small-diameter liquid cylinder 22 continuously provided concentrically with the air cylinder and suspended in the container body; and an operating member B2 which is attached in a vertically movable manner in an upward urged state by fitting a discharge head 33 to an upper end of a stem 31 comprising a liquid piston 30 and an air piston 32. A liquid in the liquid cylinder and air in the air cylinder are merged with each other and foamed by vertical movement of the operating member, and discharged as bubbles from a discharge opening 48 of the discharge head. |
