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.
