Condiment dispenser with pivotable arm

A viscous fluid dispensing apparatus comprising:

• (a) a length of resilient elastic tubing extending generally downwardly and having an upper tube section and a lower tube section;
• (b) wall means for providing a wall adjacent said upper and lower tube sections;
• and
• (c) an arm adjacent said tubing and positioned on the opposite side of said tubing from said wall means and mounted for pivotal movement about an axis moveable through dispensing and return strokes, said arm comprising an upper arm portion above the pivot axis and adjacent at least a portion of said upper tube section and a lower arm portion extending below said pivot axis and adjacent at least a portion of said lower tube section, said dispensing stroke comprising movement of said upper arm portion against a predetermined length of said upper tube section to compress said upper tube section against said lower tube section to cause a flow of fluid from said upper tube section to said lower tube section, said return stroke caused by return of said compressed upper tube section to a less compressed position thereby moving said arm through said return stroke comprising pivoting movement of said arm in a direction opposite of said dispensing stroke and causing said lower arm portion to compress and close said tubing at the lower tube section at the end of said return stroke by compression of said lower tube section between said lower arm portion and said wall means.
