material, which is open at the top Where it is provided
with an outwardly and downwardly curving gripping
?ange 12. The cylinder 10 is provided with a bottom
wall 14, which may be molded integrally therewith and is
provided with a center, preferably inwardly offset spider
16, that provides openings ‘18 into the interior of the
cylinder 10. The cylinder bottom 14 may also be pro

on the inside of it is then lowered into a laundering ?uid
in a basin while the plunger is depressed, as described
above, into the cylinder and against the article disposed
therein, to press ?uid outwardly therefrom and is then
released to create suction through openings 18, 22 and
24, to bring ?uid back into the interior of the cylinder
and through the article disposed on its bottom, to thereby
attain a laundering or rinsing action upon each stroke
