Description
BACKGROUND OF THE INVENTION
1. Field of the Invention
This invention relates to a cosmetic applicator, more particularly,
relates to a stick type cosmetic applicator for solid cosmetics,
such as a lipstick, eyebrow pencils, mascara and other solid
cosmetic materials. However, for convenience of the illustration to
clarify the characteristic feature of the present invention, a
cosmetic applicator utilized for lipstick is particularly described
as an embodiment of the present invention.
2. Description of the Prior Art
Stick type cosmetic applicators enabling a solid cosmetic contained
therein to project and retract with respect thereto have been well
known, however, many of them include therein a metallic sleeve
means provided with a pair of helical slots as an actuating means.
Therefore, the construction of the conventional applicators is
complicated, in addition, there is limitation of projecting or
retracting speed of the solid cosmetic with respect to the
applicator, since the solid cosmetic contained within the
conventional applicators is projected or retracted along only the
pair of helical slots provided in the applicator.
BRIEF SUMMARY OF THE INVENTION
A principal object of the present invention is to provide an
improved stick type cosmetic applicator which can quickly and
smoothly project and retract a solid cosmetic contained therein,
and that the solid cosmetic may be efficiently and completely used
up to the last without touching the same.
Another object of the present invention is to provide an improved
stick type cosmetic applicator which is simple in its construction
without using conventional sleeve means.
Another object of the present invention is to provide an improved
stick type cosmetic applicator capable of being produced at a very
low cost.
Still another object of the present invention is to provide an
improved stick type cosmetic applicator which can be made of
synthetic resin.
Other and more detailed objects, features and advantages of the
present invention will become apparent as the description of a
suitable form of applicator embodying the present invention is
hereinafter described.
The stick type cosmetic applicator of the present invention is
provided with a cylindrical casing, a base member rotatably
disposed at the lower end of the casing and an actuating means for
projecting and retracting a solid cosmetic contained within the
applicator. One of the characteristic features of the stick type
cosmetic applicator according to the present invention is that the
actuating means comprises a relay barrel and a saucer supporting
the cosmetic which are relatively moved with each other in the
applicator through a screw rod integrally connected to and
longitudinally extended from the center of the back of the saucer
and a screw hole provided at the center portion of the top of the
relay barrel, which is engaged with the screw rod, and which are
turnably and slidably engaged with the cylindrical casing and the
base member, respectively, by means of the key and the screw
mechanisms provided in the applicator without using any
conventional sleeve means. The projecting or retracting motion of
the solid cosmetic loaded on the saucer is smoothly and promptly
operated by the actuating means when the base member is rotated
with respect to the cylindrical casing.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
Referring now to the drawings from FIG. 1 to FIG. 3, a stick type
cosmetic applicator of the present invention comprises a
cylindrical casing 6 having a continued spiral groove 5 at the
lower part of the inside wall thereof and having a pair of
longitudinally extending key ways 12 symmetrically formed at the
upper part of the inside wall thereof with respect to an axis of
the casing; a base member 1 turnably and coaxially disposed at the
lower end of the casing 6 having an integral longitudinal, upwardly
extending short outer wall portion 4 at the peripheral edge thereof
and an integral longitudinal, upwardly extending cylindrical pillar
portion 3 at the center portion of the base member 1 which has a
pair of integral, longitudinally extending keys 2 symmetrically
formed at the outer periphery thereof with respect to an axis of
the base member; and an actuating means disposed within the
applicator which is comprises a relay barrel 9 and a saucer 15
supporting the solid cosmetic 14. The relay barrel 9 has a screw
hole 10 at the center portion of the top thereof and is provided
with a pair of integral, transversely projecting pins 7
symmetrically formed at the lower end of the outer periphery
thereof with respect to an axis thereof which engage the spiral
groove 5 of the cylindrical casing 6 and is provided with a pair of
longitudinally extending key ways 8 symmetrically formed at the
inside wall thereof with respect to an axis thereof which are
slidably engaged with the keys 2 of the pillar portion 3 of the
base member 1. The saucer 15 is provided with an integral screw rod
11 at the center portion of the back thereof which has a counter
screw at the priphery thereof with respect to the spiral groove 5
of the cylindrical casing 6 and extends longitudinally downwards
and is provided with a pair of integral, transversely projecting 13
symmetrically formed at an intermediate portion of the outer
periphery thereof with respect to an axis thereof which are
slidably engaged with the pair of key ways 12 of the cylindrical
casing 6. The screw rod 11 is engaged with the screw hole 10
provided at the center portion of the top of the barrel 9.
The applicator of the present invention has the construction as
described above, therefore, the operation for use of the same is
described hereinafter.
In the applicator shown in the FIG. 2, when the cylindrical casing
is kept in a stationary state by one hand of the user and the base
member 1 is rotated with respect to the casing 6 by the other hand,
simultaneously the cylindrical pillar portion 3 of the base member
1 is rotated to turn the relay barrel 9 through the pair of keys 2
provided on the pillar portion 3 of the base member 1 and slidably
engaged with the pair of key ways 8 provided at the inside wall of
the barrel 9, thereby the barrel 9 is elevated upwards while being
guided along the spiral groove 5 provided at the inside wall of the
casing 6 through the pair of pins 7 provided at the lower end of
the barrel 9 engaged with the spiral groove 5. Simultaneously the
saucer 15 is quickly elevated upwards in the casing 6 relative to
the rotating and elevating motion of the relay barrel 9 by the
interposition of the screw rod 11 provided at the back of the
saucer 15 and the screw hole 10 provided at the top of the relay
barrel 9 which are engaged with each other while being guided along
the pair of key ways 12 provided at the inside wall of the casing 6
through the pair of pins 13 provided on the saucer 15. Thus, the
solid cosmetic 14 contained within the applicator of the present
invention is projected smoothly and quickly from the tip of the
applicator by the novel actuating means including the key and the
screw mechanisms without using the conventional sleeve means when
the base member 1 is rotated with respect to the cylindrical casing
6 as shown in the FIG. 3. After use, the relay barrel 9 is lowered
through the guide of the spiral groove 5 by rotating the base
member 1 with respect to the casing 6 in the opposite direction,
and simultaneously the saucer 15 is quickly lowered theretogether,
thereby the projected solid cosmetic 14 may be retracted quickly to
its original position as shown in the FIG. 2.
According to the applicator of the present invention, the solid
cosmetic contained therein may efficiently and completely be used
up to the last without touching the same. Moreover, the applicator
of the present invention includes various advantageous merits that
the use and the handling thereof are very convenient, that the
construction thereof is very simple, therefore, its assembling is
very easy, and that the applicator is manufactured at a very low
cost, since all of the component elements thereof can be made of a
synthetic resin.
