“Anti-eating Face Mask”

Background of invention:
“The temptation to eat which leads one to eat excessively
is ever present and the ready availability of attractively prepared,
taste-tempting foods makes the temptation to eat
and therefore to overeat virtually irresistible.
Frequently, this temptation is so great that compulsive eating
is not uncommon and many persons
are virtually without the strength of will to resist overeating…

…Accordingly, a primary object of this invention
is to provide a new and novel device
for preventing the consumption of food by an individual.”

What a mouth full!
