My'invention relates to a new and useful im
provement in a combination tooth brush and
paste holder in which the handle of the tooth
brush serves as a container for the tooth paste
which is curved to provide a convex outer surface
and a concave inner surface. Projected through
and attached to this wall III is a feeding tube
ll threaded onto which is a brush element em
which may be automatically fed to the bristles
of the brush. It is an object of the present in
vention to provide a device of this type which will
be- simple in structure, economical of. manu
bodying the body l2 and the bristles ii. The
body I2 is provided with the cavity [4 communi
cating with which are the openings I! so that
the paste feeding into the cavity Il may pass
outwardly through the openings I5 onto the
