Description

[Detailed description of the invention] The present invention relates to a pencil sharpener that sharpens the tip of a solid bar-shaped cosmetic product, such as eyebrow ink, into an approximately elliptical cone shape, and uses a simple structure and operation to sharpen the tip of a solid bar-shaped cosmetic product into an approximately elliptical cone shape. The purpose is to ensure that the

BACKGROUND ART Conventionally, each time a solid bar-shaped cosmetic product such as eyebrow ink is consumed, it is necessary to shave the tip of the cosmetic product into a substantially pointed shape using a knife or the like to shape the tip into a shape that is easy to use.

For this reason, users have to sharpen the tip of the solid cosmetic bar with a knife every time they use it, but it is relatively difficult to sharpen the tip of the solid cosmetic bar into a shape that is easy to use. It is troublesome, and even though it is solid, it does not have that much hardness, so the sharpened tip often breaks due to a slight error in the distribution of force during the cutting process.

Furthermore, although the shape of the tip of the solid bar-shaped cosmetic product that is easiest to use is pointed and flat, it is extremely difficult to achieve such a shape manually with a knife or the like.

The present invention was devised so that the tip of a solid bar-shaped cosmetic product can be shaved into an elliptical conical shape by a simple rotational operation. By placing the cosmetic in the insertion position and rotating the cam barrel in a predetermined position with the outer circumferential surface of the cam barrel in constant contact with a predetermined point, the tip of the solid rod-shaped cosmetic inserted into the cam barrel can be roughly aligned. It is designed to be cut into an elliptical cone shape, and one embodiment of the present invention will be described below with reference to the drawings.

The solid bar-shaped cosmetic sharpener according to the present invention includes a frame body 1 as a solid bar-shaped cosmetic sharpener main body, which is rotatable from a rotating chamber part 2 and a shaving part 8 into the rotating chamber part 2. It is composed of a piece body 13 that rotates the inserted solid rod-shaped cosmetic product in a predetermined and regulated manner.

In the illustrated embodiment, an outer container 19 for storing the shavings of a solid bar-shaped cosmetic product is detachably attached to the shaving portion 8 of the frame 1.

The shaving part 8 has a shaving window 11 for protruding the cutting edge of the shaving blade 10 on an inclined plate 9 fixed at a predetermined inclination angle with respect to the insertion direction of the solid bar-shaped cosmetic. A vertically long hole is formed along the shaving window 11, and the shaving blade 10 is fixed so that the cutting edge protrudes from the shaving window 11.

There is nothing in this shaved part 8 that restricts the rotational posture of the solid bar-shaped cosmetic, and therefore sufficient space must be secured in the parts other than the inclined plate 9 so that the tip of the solid bar-shaped cosmetic does not come into contact with it. It is shaped in a certain way.

In other words, the wall portions of the scraped portion 8 other than the inclined plate 9 are simply for ensuring the attitude of the inclined plate 9 and giving desired mechanical strength to the scraped portion 8.

The rotation chamber 2 is a part in which the piece 13 inserted through the solid cosmetic bar is attached in a manner that it cannot be removed in order to rotate it in a predetermined form. The piece body 13 is rotatably but cannot be removed between the assembled cap 16 and the bridge body 13.

In the case of the illustrated embodiment, the rotation chamber 2 is formed of a cylinder wall 3, a bottom plate 4, and a cap 16, and the cylinder wall 3 has a cylindrical shape with an inner diameter that allows the piece 13 to rotate with plenty of room. It is shaped in a certain way.

The rotation chamber 2 includes a restriction reference point piece 6 that serves as a reference point for regulating the lateral direction of the piece 13 in order for the piece 13 to rotate in a predetermined manner within the rotation chamber 2. A base side 18 and two or more cam regulating pieces 7, 7, . . . are provided.

On the other hand, the piece body 13 is inserted and held in a state where it penetrates through the solid bar-shaped cosmetic, and the outer circumferential surface of the piece 13 is fixed to the regulation base piece 6 and the regulation base 18 (hereinafter referred to as "regulation" unless otherwise specified for the sake of simplicity). A cam cylinder piece 14 that is brought into contact with the cam cylinder piece 14 (represented by the base point piece 6), and a cam restriction piece that is integrally formed with this cam cylinder piece 14 and that comes into contact with the cam restriction pieces 7 individually. 7... and the same number of cam pieces 15.

This piece body 13 has an outer circumferential surface approximately ? The circular cam cylinder piece 14 is positioned at a fixed point on the regulation base piece 6,
By rotating the cosmetic bar in a predetermined position while keeping the outer peripheral surfaces in contact with each other, the tip of the inserted solid cosmetic bar that has entered the cutting portion 8 is shaved into an approximately elliptical conical shape. The basic rotation regulation structure of the piece body 13 and the rotation chamber 2 which provides the piece body 13 with the following will be explained with reference to FIG.

The outer circumferential surface of the cam cylinder piece 14 is a circular arc surface 14a, 1 centered on centers A, B, C, and D located at each node of an equilateral quadrilateral.
By connecting 4b, 14c, and 14d, it is shaped into a substantially elliptical shape.

Conical arc surfaces 14 a , 14 b , 14 C , 14
d) The restriction base point piece 6, which is in constant contact with the outer circumferential surface of the cam cylinder piece 14 shaped into a substantially elliptical shape, is such that the point where the outer circumferential surface of the cam cylinder piece 4 is in constant contact is directly above the cutting blade 10 in the cutting part 8. It is fixed to the bottom plate 4 in the same position.

With respect to the regulation base piece 6, two or more (two in the illustrated embodiment) cam regulation pieces 7, 7 are located on the side where the cam cylinder piece 14 is located with respect to the regulation base piece 6. is not particularly limited, but in order to effectively exert a good regulating force on the piece 13, it is necessary to set the base point on the regulation base point piece 6 as the apex, and draw a vertical line of the regulation base point piece 6 passing through this base point. It is desirable to set it at a position almost close to the other vertices of the equilateral triangle that is the line of symmetry.

The cam regulating pieces 7, 7 are connected to the cam piece 15. , 15, together with the fact that the outer circumferential surface of the cam cylinder piece 14 is in constant contact with the restriction base piece 6, the rotation form of the piece 13 is restricted to a predetermined one.

The rotation form of this piece body 13 is such that when the circular arc surface 14a of the outer peripheral surface of the cam cylinder piece 14 contacts the regulation base point piece 6, it rotates around the center A of this circular arc surface 14a. When each arcuate surface 14b, 14C, 14d contacts the regulation base point piece 6 in sequence, the centers B, C of the contacting arcuate surface
, D.

At this time, the centers A, B, C, and D, which are the centers of rotation, are located on a set straight line, for example, on a vertical line passing through the base point of the regulation base point piece 6 described above.

In this way, when the cam cylinder piece 14 is rotating in a predetermined manner with its outer peripheral surface in contact with the restriction base piece 6, the cam piece 1
5 also regulates the rotational posture of the piece body 13 by bringing its peripheral surface into contact with the cam regulating piece 7. Therefore, the shape of the cam piece 15 is similar to that of the circular arc surface 14? In the rotation range where the cam contacts the restriction base piece 6, the cam arc side 15a with a radius that contacts the cam restriction piece 7 with the center A as the center, and the rotation where the circular arc surface 14b contacts the restriction base piece 6 in the same manner. The cam arc side 15b centered on the center B in the range, the cam arc side 15C centered on the offshore center C in the rotation range where the arc surface 14C contacts the regulation base piece 6, and the arc surface 14d. Regulation base point piece 6
The cam arc side 1 centered on the offshore center D in the rotation range that comes into contact with
5d are connected to each other.

In the illustrated embodiment, since there are two cam regulating pieces 7, the cam pieces 15 correspond to both the cam regulating pieces 7, 7.

, 15 are formed integrally with the cam cylinder piece 14 in the above-described predetermined shape.

By the way, as is clear from the basic configuration diagram of the cam piece 15 shown in FIG. Since they are simply connected at the intersection, each cam arc side 15 a , 1
Since the connecting portions 5b, 15c, and 15d are curved discontinuous points, there is a risk that the rotational movement of the piece body 13 may not be smooth.

Therefore, when actually manufacturing the cam pieces 15, each cam arc side 15 a, 15 b, 15 c, 15 d
It is desirable that the connecting point portion be a continuous curve that is as close to the basic shape as possible.

In this way, the piece body 13 is formed by integrally forming the cam cylinder piece 14 and the cam piece 15, and the piece body 13 rotates in an upright position without being tilted in the rotation chamber 2. In the illustrated embodiment, the cam cylinder piece 14 is given a certain length, and both cam pieces 15, 15 are integrally formed at the upper and lower ends of the cam cylinder piece 14, respectively. attitude.

Therefore, this cam piece 15. , 15 are also provided at the upper and lower ends of the rotation chamber 2, and the rotation chamber of the restriction base piece 6 that similarly contacts the outer peripheral surface of the cam cylinder piece 14. Rotating communication window 5 that communicates between the part 2 and the scraping part 8
A regulating base side 18 is formed into a section, and the upper end outer circumferential surface of the cam cylinder piece 14 comes into contact with the rotating opening 17 portion of the cap 16 directly above the regulating base piece 6 .

In this way, the piece body 13 has its cam cylinder piece 14 and cam piece 15.
As a result, it is assembled and held rotatably in a fixed form within the rotation chamber 2, so that it penetrates into the shaved part 8 of the solid rod-shaped cosmetic inserted into the cam cylinder piece 14 of the piece body 13. By rotating the solid bar-shaped cosmetic, the tip rotates integrally with the piece body 13, and therefore the regulation base point piece 6
The peripheral surface facing the regulation reference point piece 6 is always in contact with the shaving blade 10 located directly below the regulation base point piece 6, and as a result, the tip of the solid bar-shaped cosmetic is sharpened into a pointed shape according to the inclination angle of the shaving blade 10. It will be done.

As is clear from FIG. 4, since the cam cylinder piece 14 has a wall thickness, the cutting blade 10 is located inward from the outer peripheral surface of the cam cylinder piece 14 by the thickness of the cam cylinder piece 14. Therefore, between the rotation chamber part 2 and the cut part 8, there is a step part 1.
2, and has a width approximately equal to the wall thickness of this cam cylinder piece 4, which makes good contact with the peripheral surface shaving blade 10 of the solid bar-shaped cosmetic facing the regulation base point piece 6. Become.

As is clear from the above description, in the solid bar-shaped cosmetic sharpener according to the present invention, the cam cylinder piece 14 into which the solid bar-shaped cosmetic is inserted and held rotates in a fixed manner with its outer peripheral surface in contact with the regulation reference point piece 6. , the solid bar-shaped cosmetic rotates in a substantially elliptical shape along the outer circumferential surface of the cam cylinder piece 14, so that the tip of the solid bar-shaped cosmetic is rotated by the obliquely arranged scraping blade 1.
0, and its structure is such that the piece body 13, in which the cam piece 15 is integrally formed with the cam cylinder piece 14, is assembled in the rotation chamber 2 so as to be rotatable in a fixed position. , the structure is extremely simple, and the solid bar-shaped cosmetics can be used simply by inserting the tip into the cam cylinder piece 14 and rotating it, making it easy to use. It has beneficial effects.
