PURPOSE:To inject fine bubbles by a method wherein when a push button type injection head part is depressed to push down the piston part, foams are made to generate by the contact between a content which flows in from the container and air which flow in from the outside through the piston mechanism. CONSTITUTION:The bubbling pump has a lid 1 which is screwed on the mouth part of a content container, and a push button type injection head part 2 is fitted on a cylindrical upward protruding part 21 which stands on the top of the lid 1, and the push button type injection head part 2 is energized upward by a spring 23. Also, on the inside of the lid 1, a cylinder part 3 of a tube-shape with bottom, in which a stretchable member 14 with numerous communicating holes is fitted is attached, and in the cylinder part 3, a piston 4 on which a tubular part 9 extending upward is integrally provided is fitted. The upper end of the tubular part 9 is fitted and fixed to the injection head part 2. When the injection head pat 2 is depressed, bubbles are made to generate by the contact between a content which flows in from the container, and air which flows in from the outside through the piston mechanism, and the bubbles are injected to the outside from an injection port 22. |
