It is a mesh shape set in the form which traverses between the inner peripheral surfaces of the said cylindrical part.

(3) In the above (1), (2),

The bubble generation function,

The cylindrical portions are set at portions separated from each other in the flow direction of the contents.

(4) As described in (3),

The cylindrical portion,

An upstream side member integrally formed with the inflow side portion of the contents, the first foaming action portion, and the inner and outer communicating portions;

The outflow side portion of the contents and the second foaming action portion become a downstream member integrally formed.

The present invention is directed to a foam-forming attachment of the container contents having the above-described configuration, and a pump-type product and an aerosol-type product provided with the foam-forming attachment.

Thus, since the present invention uses a foam generating attachment, which is a cylindrical portion in the form of being mounted on the outside, for example, to remove bubbles on the size of the foam producing member, It is possible to further simplify the mounting work itself.

In addition, foaming can be achieved in various liquid contents discharge mechanisms which do not have the foaming function of the pump container or the aerosol container.
