Foamer dispenser

A foamer dispenser comprising:

• a base cap fixedly held at a container mouth;
• two pumps attached to the base cap and configured to separately suck, pressurize, and pressure-feed ambient air and the liquid contents filled in the container;
• a depression head for defining a merging space for merging outlet passages of the pumps with each other, the depression head having an ejecting end communicated with the outside, and the depression head having an internal passage for communicating the merging space with the ejecting end, so as to eject contents mixed with the ambient air from the ejecting end by repeating depressing and returning operations of the depression head;
• and a foaming element disposed within the internal passage of the depression head and configured to foam the contents mixed with the ambient air;
• wherein said foaming element comprises:
• a jet ring having an inlet opening with an opening area narrower than that of said internal passage of said depression head, the jet ring comprising a tubular body with an opening area larger than that of the inlet opening and communicated with said internal passage of said depression head;
• and a mesh disposed within said tubular body of said jet ring so as to face to said inlet opening of said jet ring, said mesh having a number of fine holes to be contacted with the contents mixed with the ambient air and supplied from said inlet opening to allow a part of the contents to pass through said mesh;
• and
• wherein said mesh has an opening diameter φ2 which is 2.0 to 3.5 times as large as an opening diameter φ1 at the inlet opening of said jet ring.
