Apparatus for making content liquid foamy for discharge and systems and methods thereof

A foaming dispenser for making content liquid discharge foamy by mixing air flow from an air chamber with content liquid flow from a liquid chamber, comprising:

• a mixing chamber configured to mix air and content liquid;
• a porous member between an air passage from the air chamber and the mixing chamber;
• a liquid passage from the liquid chamber to the mixing chamber, the liquid passage having a first liquid passage and a plurality of second liquid passages, the liquid passage being configured such that content liquid flows from the first liquid passage to the second liquid passages to the mixing chamber;
• and
• a flow path, from the porous member to an opening of a cap discharge head where the foamy content liquid is discharged from the foaming dispenser, including a vertical flow and a horizontal flow, the vertical flow being parallel to a stem which extends into the liquid chamber and forms a part of the liquid passage, and the vertical flow having a length that is equal to or greater than the horizontal flow, wherein
• the second liquid passages are configured to provide flow of the content liquid in at least two directions, and
• the second liquid passages are contiguous with the first liquid passage.
