• (I) the liquid contacting steps including:
• (a) fitting said annular pieces in a tubular container means, said container means stacking said annular pieces, said container means having upper and lower ends and being open at both ends and including retention means at the lower end for preventing said annular pieces from falling from said container;
• (b) fitting said upper end of said container to a liquid intake and discharge means;
• (c) fitting said lower end of said container means with releasable tip means;
• (d) drawing said liquid solution into said container means by said liquid intake and discharge means;
• (e) exhausting said liquid solution from said container by said liquid intake and discharge means;
• (II) the storing steps including:
• (f) removing said liquid intake and discharge means from said container means;
• (g) releasably capping the upper end of said container means and the lower end of said tip means;
• (III) the dispensing steps including:
• (h) removing the caps and tip means;
• (i) fitting said container means to a dispensing means, said dispensing means including means for selectively overcoming said retention means;
• and
