Abstract
A foam dispenser includes an elongated squeezable relatively small vertical container having a top disposed open neck and being otherwise sealed. An elongated vertical member has hollow upper and lower sections which communicate with each other. The upper end of the upper section has a relatively large opening. The lower section has a relatively small opening. The member is sealed in the neck with the large opening disposed above the neck and constituting a discharge orifice. At least two vertically spaced horizontal sieves are sealed one below the other in the orifice. The upper one of the sieves is a fine sieve, the lower one of the sieves is a coarser sieve.
