This invention relates to smoking appliances,
such as tobacco pipes.
(01. 1s1_z02)
Its utility is best exem
pli?ed in a tobacco pipe, because the tobacco
juice therein‘ detracts from the comfort and
pleasure of the smoker and has offered problems
that have long perplexed the art.
One object of the invention is to provide a
simple, discardable device of improved inexpen
sive construction for absorbing the tobacco juice.
Another object of the invention is the provi
sion of a device of the nature set forth having
improved means comprising a smoke ?ltering and
juice absorbingv portion and a vsafety portion for
absorption of any excess ofjuice without retard‘
