    DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

    (9) A preferred embodiment of the present invention will be hereafter described in detail with reference to the accompanying drawings.

    (10) A cosmetic pencil of the present invention includes, as illustrated in FIGS. 1 to 7, a body 10, a screw bushing 20, a lead holder 30, a rotator 40, and a sharpener 50.

    (11) The body 10 has a tubular structure, and is formed with a stepped assembling passageway 11 of which a diameter of a rear inner portion is larger than that of a front inner portion.

    (12) The screw bushing 20 is inserted in the stepped assembling passageway 11 of the body in such a way that it is fixed to the body to prevent mutual rotation between the screw bushing and the body, and is itself formed with a threaded passageway 21.

    (13) The lead holder 30 is formed with a threaded portion 31 which is threadedly engaged with the threaded passageway 21 of the screw bushing 20, and also formed with a lead assembling socket 32, in which a lead 2 is seated, on a front portion thereof.

    (14) In this instance, tension pieces 33b operating inwardly and outwardly are segmented by slits 33a which are formed in a longitudinal direction, extending around the lead assembling socket 32 and thus the lead 2 is gripped by the tension pieces 33b when the lead is inserted.

    (15) That is, the lead assembling socket 32 is formed in such a way that the inner diameter portion of an opening having the tension pieces 33b protrudes slightly inwardly to form a stepped portion, thereby supporting the lead 2 with a gripping pressure.

    (16) Also, the lead holder 30 is formed with a polygonal insertion opening 35 at the rear portion thereof in the longitudinal direction.

    (17) The rotator 40 is inserted for axial rotation into a rear portion of the body 10, and a ring-shaped locking boss 42 protrudes from an outer circumferential portion of the rotator 40, and is inserted in the body 10 to prevent the rotator from being released from the body.

    (18) The front portion of the rotator 40 is formed with a polygonal insertion rod 45 which is inserted in the polygonal insertion opening 35 of the lead holder and is turned with the lead holder 30.

    (19) In this instance, the polygonal insertion hole 35 of the lead holder 30 and the polygonal insertion rod 45 of the rotator 40 can be correspondingly formed to have a sectional structure, such as a triangular, rectangular, or pentagonal shape, but the rectangular sectional structure is preferable in view of machinability, rigidity and assembling workability.

    (20) The rear portion of the rotator 40 is formed with an assembling groove 41 to receive the sharpener 50 therein, so that a user can take out and use the sharpener 50 if necessary.

    (21) The sharpener 50 has a handle body 51, a blade 52 to sharpen the lead 2 inserted in the handle body, and a plug 53 engaged to a rear portion.

    (22) The lead 2 is preferably made of at least two colors, but is not illustrated in the drawings.

    (23) A reference numeral 53 indicates a plug fitted into the sharpener, and 60 indicates a finishing cap.

    (24) The operation of the cosmetic pencil according to the present invention will be described.

    (25) First of all, a process of assembling the cosmetic pencil according to the present invention will be described.

    (26) The threaded portion 31 of the lead holder 30 is threadedly engaged with the threaded passageway 21 of the screw bushing 20, and the lead 2 is inserted into the lead assembling socket 32 of the front portion of the lead holder 30.

    (27) The polygonal insertion rod 45 of the rotator 40 is inserted and assembled to the polygonal insertion opening 35 of the rear portion of the lead holder 30.

    (28) The lead holder 30 is fitted into the rear portion of the tubular body 10, and the screw bushing 20 is inserted and fixed to the stepped assembling hole 11 for the purpose of mutual rotation.

    (29) The sharpener 50 is assembled to the assembling groove 41 of the rear portion of the rotator 40.

    (30) The cosmetic pencil of the present invention which is assembled by the above process includes the body 10, the screw bushing 20, the lead holder 30, the rotator 40, and the sharpener 50. In particular, the lead holder 30 is not operatively engaged with the rotator 40 to provide longitudinal movement, but is threadedly engaged with the screw bushing 20. Therefore, since the structures of the rotator 40 and the screw bushing 20 are simplified, it is possible to prevent poor molding of the components, and thus the productivity thereof and the assembling workability are improved.

    (31) It should be known that the order of assembling the components can be changed.

    (32) The cosmetic pencil of the present invention which is assembled by the above process can propel the lead 2 out from the body 10.

    (33) That is, if the rotator 40 is turned, the polygonal insertion rod 45 of the rotator 40 is fitted into the polygonal insertion hole 35 of the lead holder 30, and thus the lead holder 30 is turned.

    (34) If the lead holder 30 is turned, since the threaded portion 31 of the lead holder is threadedly engaged with the threaded passageway 21 of the screw bushing 20, the lead holder is not moved in a straight way, but is axially moved while being spirally turned.

    (35) In this instance, the polygonal insertion rod 45 of the rotator 40 which is inserted in the polygonal insertion socket 35 of the rear portion of the lead holder 30 serves as a guide for the lead holder 30 which is axially moved, so that the lead 2 can be stably moved in an axial direction.

    (36) As the lead holder 30 smoothly propels the lead 2, which is inserted in the lead assembling socket 32, not by moving the lead in only the axial direction, but by spirally turning the lead, the lead 2 is prevented from being released from the lead assembling socket 32 of the lead holder.

    (37) Even though there is no separate component for fixing the lead to the lead assembling socket 32 of the lead holder, the spirally turning method of the lead holder 30 can solve the problem in of preventing the lead 2 being released from the lead assembling socket 32 of the lead holder.

    (38) In addition, the lead 2 is made of the plurality of colors, and the lead is drawn out from the body 10 not by the axial movement, but by the spiral turning, thereby visually highlighting a marbling effect, and thus obtaining an additional esthetic effect of the lead.

    (39) While the present invention has been described with reference to the particular illustrative embodiment, it is not to be restricted by the embodiment but only by the appended claims. It is to be appreciated that those skilled in the art can change or modify the embodiments without departing from the scope and spirit of the present invention.
