LIQUID PAINTING INSTRUMENT
BACKGROUND OF THE INVENTION
Field of the Invention
This invention relates to liquid painting instruments
including a cosmetic applicator for painting liquid cosmetics,
a writing pen for applying ink, or the like.
Prior Art
Conventional liquid painting instruments include
such type of painting instrument that comprises a pipe-like
pen point core body having a cross-sectionally circular
configuration and a pen point cover made of an elastic porous
material and put on the outer peripheral surface of the core
body.
With the above painting instrument, there has been
involved such a drawback that is inconvenient in painting
a phase or a line, mainly derived from the circular
configuratibn of the pen point core body.
SUMMARY OF THE INVENTION
The present invention is therfore aimed at the
provision of such an improved liquid painting instrument that
is not only capable of freely effecting both the phase painting
and the line painting, but also capable of allowing the pen
point to be deformed to an appropriate state for effecting
respective pointing works.
In order to achieve the above object, the liquid
painting instrument according to the present invention has
been conceived and completed, comprising a pipe-like pen point
core body of substantially oval configuration in cross-section,
. , . . - - :, .

a pair of longitudinal slits oppositely provided on both end
portions of the major axis of the oval configuration so that
the core body may easily be elastically deformed or bent in
the direction of the minor axis of the oval configuration,
and a pen point cover made of an elastic porous material and
put on the outer peripheral surface of the core body.
In use, when the painting is desired, such portion
of the pen point cover can be used that corresponds to either
end portion of the minor axis of the oval configuration of
the pen point core body. In this case, both slits oppositely
provided at end portions of the major axis of the oval
configuration on the pen point core body allow the latter
to be softly bent for effecting the phase painting as desired.
While, when the line painting is to be done, the painting
work can be effected using such portion of the pen point cover
that corresponds to either end portion of the major axis of
the oval configuration of the pen point core body. In this
case, the pen point core body is difficult to be bent and
appropriately exerts its rigidity so that the desired line
painting may be conveniently effected.

DETAILED DESCRIPTION AND THE PREFERRED EMBODIMENTS
Referring now to the drawings, the present invention
will be described further in detail with respect to preferred
embodiments. In Figs. 1 - 3 which illustrate a first
embodiment, a pen oint core body 2 made of a plastic material
is of substatially oval configuration in cross-section and
has a pair of longitudinal slits 1 oppositely provided on
both end portions of the major axis of the oval configuration,
and thus the core body 2 posseses such property that is easy
to be elastically deformed or bent in the direction of the
minor axis of the oval configuration. Further, the pen point
core body 2 is integrally provided with a connecting tubular
portion 4 on upper end thereof, an engaging tubular portion
5 on substantially middle portion thereof, a collar poriton
6 between the connecting tubular poriton 4 and the engaging
tubular portion 5, and an undercut engaging projection 7 on
outer surface of the engaging tubular poriton 5. The pen
point core body 2 is fixed with the connecting tubular portin
fitted into a lower end opening of a main shaft 8. The pen
point core body 1 fuxther has an ink guide hole 10 provided
therein for communicating with an ink tank 9 in the main shaft
8. A hollow fingerstall-type pen point cover 3 which is made
of an elastic porous material such as a sponge is put on the
outer peripheral surface of the core body 1, with inner face
; portion of the opening end thereof closely fixed to outer
face portion of the engaging tubular portion 5. A front shaft

11 is fixed on a lower end peripheral face portion of the
main shaft 8, with both the pen point core body 2 and a lower
half portion of the pen point cover 3 covered thereby.
The pen point cover 3 is fixedly sandwiched between
the inner surface of the front shaft 11 and the outer surface
of the engaging tubular poriton 5. Further, an undercut
engaging projection 12 is provided on the inner surface of
the front shaft 11 at such a position that has a phase
difference from the engaging projection 7 of the engaging
tubular portion 5.
Accordingly, the pen point cover 3 is not only fixed
by the pressure exerted by both the front shaft 11 and the
engaging tubular poriton 5, but also strongly fastened by
both the engaging projection 7 of the engaging tubular portion
5 and the engaging projection 12 of the front shaft 11 lest
it should slip out of the pen point core body 2. Ink in the
ink tank 9 is discharged through the ink guide hole 10 mainly
past a lower end opening of the pen point core 2 to moisten
the pen point cover 3 which in turn can be used for painting.
Further, since the ink can also be discharged through the
- slits 1, there can be effected an easy supply of the ink over
a wide area of the pen point cover 3.
Fig. 4 illustrates a second embodiment of the present
invention which comprises the pen point core body 2 merely
provided on the front end of a painting shaft 13. Unlike
that of the first embodiment which comprises the ink tank
within the main shaft 8 to be capable of supplying the ink
to the pen point cover 3, it is such arranged that the pen
; .

,-,, ~ . - - ~, . . ..
-` 20331~2
point cover 3 is immersed in ink every time it is used for
painting.
As described above, the liquid pointing instrument
of the present invetnion is capable of freely effecting both
the face painting and the line painting such that, while when
painting a face, the pen point can be softly bent, when
painting a line, is difficult to be bent with the rigidity
thereof appropriately kept. Accordingly, it is very improved
from the view point of use in that any desired face and line
paintings can be effected in such manners as appropriate for
respective painting purpose.
