Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a cosmetic pencil such as an eyebrow, an eyeliner and a lip liner, and more particularly to an improvement of a cosmetic pencil for drawing a thin line.

[0002]

[Prior art]

 To date, cosmetic pencils for drawing fine lines of this kind have been of the type similar to wooden colored pencils, and are made thinner by cutting the tip of the core with the surrounding wooden stick. It had been. However, like mechanical pencils for pencils, there is a growing need for mechanical types, and cosmetic pencils are also required to have mechanical types, and various mechanical type cosmetic pencils have been developed.

The basic structure of this mechanical type is a cylindrical pencil main body composed of a front end side and a rear end side that are rotatably combined with each other, and a rear end side main body is rotated in the main body to move the inside of the main body. It is equipped with a lead holder that can move forward and backward, and is used with the lead protruding from the opening at the tip of the main body. In such a basic structure, how to reduce the thickness of the core in order to draw a thin line was an important technical issue.

[0004] A core thickness of about 2 mm, which is an almost limitable value for enduring use while maintaining an appropriate softness of a material, is conventionally known as a cosmetic pencil having a thinnest core. Also, the diameter of the core should be about 3 mm or more, and a pen corer should be installed on the tail plug side of the pen to draw a fine line, and the tip of the core with a diameter of 3 mm or more should be scraped with the core corer. It is known to have been made.

However, a thin core with a diameter of 2 mm is prone to breakage, and therefore there is a problem in that the material cannot be made too soft. With a core sharpener, despite the diameter being 3 mm, it is actually Only the central part with a diameter of 1 to 2 mm can be used for, and the other outer parts were scraped away and wasted.

[0006]

[Problems to be solved by the device]

 Therefore, in consideration of the above-mentioned conventional problems, the present invention has a core material having a diameter of about 3 mm or more so as to be hard to break and endure stable use while maintaining an appropriate softness of the material. However, there is a technical problem in providing a cosmetic pencil that can draw thin lines.

[0007]

Means and Action for Solving the Problems

 According to the present invention, a cylindrical pencil body including a front end side cylinder and a rear end side cylinder which are rotatably combined with each other, and a rearward end cylinder can be moved forward and backward by rotating the rear end side cylinder. In a pencil that is equipped with a core holder that is capable of projecting the core material from the tip opening of the tip-side cylinder, the end surface of the tip-side cylinder has an elliptical shape, so that Can be used as an elliptical shape.

With such a configuration, even if a core material having a size of about 3 mm or more is used, the tip surface of the core material to be actually used is rubbed along the tip opening shape of the pencil, so that an elliptical shape can be easily obtained. It is possible to draw a thick line with an elliptical surface and a thin line with a sharp tip. Further, since a relatively thick core material can be used, a core material having an appropriate softness can be used, and it is possible to provide a cosmetic pencil that is capable of drawing a thin line and at the same time not easily broken.

As a driving mechanism of the pencil, a driving piece having a spiral screw on the outer periphery is fixed to the rear end side of the core holder, and a screw groove that meshes with the spiral screw of the driving piece is formed on the inner wall of the rear end side cylinder. The core member holder has a plurality of claw members for holding the core material that protrudes annularly toward the tip side, and the claw member is provided on the inner peripheral wall of the tip side cylindrical body. It can be configured by forming a guide groove that can be fitted and slidable.

[0010]

[Embodiment of the invention]

 1 to 4 show an embodiment of a cosmetic pencil according to the present invention, in which a cylindrical pencil body 1 composed of a front end side and a rear end side, which are rotatably combined with each other, and a forward / backward movement in the main body. It has a core holder 2.

The pencil main body 1 is composed of a tubular rear end side cylinder body 11 having a closed base end and an open front end, and a front end side cylinder body 12 whose front and rear ends are both open. The end portion has a stepped portion 12a having a reduced outer diameter so that it can be inserted into the opening edge portion of the rear end side cylinder 11. Two parallel annular projections 12b and 12b are formed at a predetermined interval on the outer circumference of the stepped portion 12a, and the projections are fitted on the inner circumference of the opening edge of the rear end side cylinder 11. Freely formed annular grooves 11b, 11b are formed. With this configuration, when the step portion 12a of the front end side cylinder body 12 is inserted into the opening edge portion of the rear end side cylinder body 11, the annular projection 12b is fitted into the annular groove 11b with a click feeling. And are rotatably connected to each other.

A drive piece 3 having a spiral screw thread 3 a formed on the outer periphery is fixed to the rear end of the core material holder 2. On the other hand, on the inner wall of the rear end side cylinder 11, a socket 4 having an inner peripheral surface formed with a screw groove that meshes with the screw thread 3a of the driving piece 3 is fixed. A plurality of claw members 2a, 2a, for holding a core material, which will be described later, are provided on the outer periphery of the tip end portion of the core material holder 2 so as to project annularly toward the tip end side. On the inner peripheral wall of the distal end side cylinder 12, guide grooves 12c, 12c ... In which the claw members 2a, 2a ... Can be fitted and slidable are formed parallel to the longitudinal direction.

Further, the tip end opening 121 of the tip end side cylinder 12 is formed in a shape obliquely cut in the vertical direction, and the opening shape is formed in an elliptical shape. In the makeup pencil configured as described above, as shown in FIG. 3, the core material P, which is a cosmetic material, has the tip portion of the core material holder 2 gripped around the base end portion by the claw members 2a, 2a. Be installed. The tip shape of the core material P is a shape obtained by obliquely cutting along the shape of the tip opening 121 of the tip side cylinder 12. The core material P used here has a diameter of about 3 mm, which is appropriate in order to allow appropriate softness and fine line drawing, but it is natural that it can be appropriately changed according to the material and application.

In such a configuration, the core material holder 2 has the claw members 2a, 2a ... Fixed at its tip fitted into the guide grooves 12c, 12c. Therefore, when the front end side cylinder body 12 is fixed and the rear end side cylinder body 11 is rotated clockwise, the socket 4 fixed to the inner wall of the rear end side cylinder body 11 is simultaneously rotated and the socket. The drive piece 3 meshed with the inner peripheral thread groove is slid forward, and the core material holder 2 fixed to the tip of the drive piece 3 moves forward to project the core material P from the opening of the tip side cylinder 12. Will be done. On the contrary, when it is rotated counterclockwise, the core holder 2 is retracted to the rear end side and the core P is housed in the pencil.

The cosmetic pencil according to the present invention is configured as described above, and the tip opening is formed in an elliptical shape. Therefore, the tip of the core material P is easily rubbed in conformity with the shape of the tip opening to form an elliptical shape. It can be shaped, and when used, a thick line can be drawn by using an elliptical surface, and a thin line can be drawn by pushing up the core a little and using the tip.

Further, the round core can be used in the same manner as the elliptic core in this way, and a simple and inexpensive mold is used without using a high-cost mold required for manufacturing the elliptical core. It is possible to provide cosmetic pencils.
