stem and promotes rising and retention of the liquid product
in the hollow portion 14 (column 4, lines 35 through 39). The
liquid product L passes along the surface of the tuft, not
between the hairs (column 8, lines 3 through 8). With this
arrangement, it is possible to apply nail varnish over a whole
hand without having to reimmerse the hairs 8 of the brush 3 in
the liquid product of the bottle 2 (column 5, lines 10 through
14). The Buehrer reference (Fig. 2) teaches a fountain marker
brush comprising a body 1 filled with ink including a lower
nipple 9 and nozzle 11. The nozzle has a central threaded
hole 12, with a marking point 2 of the brush screwed therein.
The marking point can be an interchangeable point made of felt
(preferred), soft or stiff hair, sponge, rolled cloth, or any
other firm flexible capillary material (page 1, lines 82
through 88). Viewing Figs. 2 and 3, the interior threaded
hole of the nozzle includes a series of small ink feeding
channels 13 which lead from the space above the nozzle and
“terminate just inside the extreme end of the nozzle as shown”
(page 1, lines 96 through 101). The upper end of the marking
point is completely surrounded by an auxiliary ink reservoir
