Description

The present invention relates to writing means for makeup, such as a writing instrument used for drawing eyebrows, eyeliner, body hair, and the like.

Since the pen shaft stands perpendicular to the writing surface, when applying makeup while looking in the mirror, the pen shaft will not interfere with the makeup process, making it difficult to see or hide the essential parts of the makeup. is a drawback. There is also a structure in which writing is performed using a writing roller with a rotating structure. Moreover, it is limited to one line of writing.

Special Table No. 2007-536136

As in Patent Document 1, in a conventional writing instrument for makeup, the makeup part and the axis of the handle of the writing instrument are perpendicular to each other. I want to solve In addition, it is possible to freely write not only by drawing a single line but also by contacting a point, a line, or a plane. Furthermore, in consideration of rehabilitation from burns and fighting illnesses, and a nursing care society, it is also important that makeup can be applied easily by a third party who provides care.
Focusing on such problems, the technical problem of the present invention is to make it possible to retreat to a desired part so that the makeup part is not hidden by the handle of the writing instrument, etc., to make more stable and precise makeup, and to make points, lines, To realize a writing utensil capable of freely applying makeup such as a mask.

The technical problems of the present invention are solved by the following means. Claim 1 has at least one writing section formed by surrounding an ink holding section that absorbs and holds ink with a support section made of synthetic resin and forming an outer shape on a circle including an ellipse or a part of a circle, Alternatively, it is a writing instrument characterized by having a structure having a spirally continuous ink outlet, and having an ink reservoir connected to the ink holding section. As the ink holding portion, for example, it is possible to hold the ink by impregnating it with cloth or cotton, and a fibrous material to which the ink is constantly supplied from the ink reservoir portion is suitable.

According to a second aspect of the present invention, as a structure in which the circle including the ellipse of the writing part or a part of the circle can be rotated, the shaft having the ink reservoir part is inserted into a cylindrical gripping part. The writing instrument according to claim 1.

According to claim 3, a face piece that absorbs and holds ink is wound around the outer periphery of a plurality of ink holding parts and connected, and the writing part is in contact with the surface and applied, or the direction or angle of the writing part is changed. 2. A writing instrument as claimed in claim 1, characterized in that variable means are interposed.

According to a fourth aspect of the present invention, the sealing surface that closes the outer periphery of the ink holding portion has a plurality of projections independent of each other, and is connected to the ink holding portion so that the ink comes out from the tip of each projection. The writing instrument according to claim 1, claim 2, or claim 3, characterized in that: Since ink comes out from the tip of each projection, pointillism is possible.

In claim 5, in order to manufacture a structure in which the ink outlet continues in a spiral shape, the spiral surface of a heat-resistant spiral core is covered with a synthetic resin layer, and then the heat-resistant core is removed to form a spiral shape. A method for manufacturing a spiral writing part, characterized in that the tip of a synthetic resin layer is removed to form an ink outlet.

As in claim 1, the ink holding portion, for example cloth or cotton impregnated with ink, which has the function of absorbing and holding ink, is surrounded by a support plate made of synthetic resin, and the circle or part of a circle including an ellipse is surrounded by a support plate made of synthetic resin. Since it has one or more writing parts formed by forming an outer shape on the surface, one or more drawing lines can be drawn at once, which is efficient. In the case of a single writing section, a finer line can be drawn by making the two support plates soft and pinching them between the thumb and forefinger and applying pressure. Alternatively, since the ink outlets are spirally parallel, a plurality of oblique straight lines can be drawn at the same time. Since the ink reservoir is connected to the ink holding section, the ink is always supplied from the ink reservoir.

According to a second aspect of the present invention, a structure in which a circle or a part of a circle containing an ellipse of the writing part can be smoothly rotated is obtained by inserting the shaft having the ink reservoir part into a gripping part made of a cylindrical body. , even if the cylindrical body is strongly gripped, the shaft having the ink reservoir can be smoothly rotated together with the writing section. Alternatively, a free means is interposed in the handle so that the direction and angle of the writing part can be freely changed according to preference, so that makeup work can be facilitated. In the case of a structure in which a part of the circle rotates, it is also possible to apply a rotational force while applying writing pressure by pressing the part where the circle is missing with a fingertip.

As in claim 3, since the face pieces that absorb and retain the ink are wound around the outer periphery of the plurality of ink holding portions and connected, the writing portions can be in contact with each other to apply the ink. As the flexible means, a freely deformable flexible material or rubber may be interposed, or a ball joint may be used for a flexible structure. As a result, the T-shaped neck portion of FIGS. 1 to 3 can be bent to be deformed into a shape other than the T-shape, and the angle and direction can be changed as desired.

According to a fourth aspect of the present invention, the sealing surface that closes the outer periphery of the ink holding portion has a plurality of projections independent of each other, and is connected to the ink holding portion so that the ink flows out from the tip of each projection. , and since the ink comes out from the tip of each projection, stippling is easy.

As in claim 5, in order to manufacture a structure in which the ink outlet continues in a spiral shape, the spiral surface of a heat-resistant spiral core is covered with a synthetic resin layer, and then the heat-resistant core is removed to form a spiral shape. Since the ink outlet is formed by removing the pointed end of the synthetic resin layer, the ink outlet can be formed in a spirally continuous shape. As a result, multiple spirally inclined straight lines can be drawn simultaneously.

1A and 1B are a plan view and a front view of a writing instrument for makeup according to the present invention; FIG. FIG. 2 is a longitudinal sectional view of FIG. 1; It is the longitudinal cross-sectional view which wound and connected the facepiece to the outer periphery of the writing part. FIG. 4 is a cross-sectional view showing a method of manufacturing a writing part with a spiral structure; FIG. 4 is a cross-sectional view showing a completed state of the writing part with a helical structure; FIG. 10 is a cross-sectional view showing a method of manufacturing a writing unit capable of stippling; FIG. 4 is a cross-sectional view showing a completed state of a writing unit capable of stippling.

Next, an embodiment of how the writing instrument for makeup according to the present invention is practically embodied will be described. FIG. 1 is a plan view and a front view of a writing instrument for makeup according to the present invention, and FIG. 2 is a longitudinal sectional view thereof. 1 is a handle held by hand, and an ink reservoir 2 is provided inside. 3 is a writing section from which ink comes out, and is composed of three disc-shaped sets 31, 32, and 33. As shown in FIG. Each of the writing sections 31, 32, 33 is sandwiched between support layers 51, 52, 53 of synthetic resin plates to prevent leakage of ink by sandwiching ink retaining layers 41, 42, 43 for absorbing and retaining ink. For the ink retaining layers 41, 42 and 43, materials such as cloth and fibrous materials such as cotton are suitable. Each of the ink holding layers 41, 42, 43 is connected to the ink reservoir 2 by the supply channel 6, and is constantly replenished with ink.

The outer shape of each writing part 31, 32, 33 may be a circular shape or an elliptical shape close to a circular shape. In short, any shape may be used as long as it is easy to rotate. Between the handle 1 and the writing part 3, there is formed a stopper 7 consisting of a depression that is large enough for a finger to enter. In the illustrated example, there are three disc-shaped writing units, but a single unit will suffice.

Now, when one finger is inserted into the recessed stopper 7 to lightly support and stabilize the writing section 3, when a rotational force is applied to the writing section 3 by the handle 1, three sets of writing sections 31 are formed. , 32 and 33 are rotated to draw three straight lines on the peripheries of the ink retaining layers 41, 42 and 43. FIG. Therefore, if there are two sets of writing units 3, two straight lines are drawn at the same time. If the portion of the recessed stopper 7 is made of a soft material that undergoes plastic deformation or elastic deformation such as rubber, the direction and angle can be freely changed with the recessed stopper 7 as a fulcrum. become free and easy. The number of dimples is arbitrary and matches the number of fingers to be inserted.

When it is necessary to firmly grip and rotate the writing part accurately, insert the handle 1 having the ink reservoir 2 into the cylindrical body C as shown in FIG. , the handle 1 inside can be rotated together with the writing part 3. If it is desired to rotate the handle 1 more smoothly and accurately, the outer diameter of the handle 1 and the inner diameter of the cylindrical body C should be brought into close contact with each other, and a lubricating material such as oil should be applied between them so that the cylindrical body C and the handle 1 face each other. It suffices to insert pins P, P into both ends of the handle 1 so as to prevent linear movement. If it is desired to further reduce the relative movement and smooth the rotation of the writing section 3, it is preferable to use a thrust bearing together.

FIG. 3 shows a case in which the writing area is made wider, and the drawing shows three (two or four or more adjacent) ink holding layers 41, 42, and 43, each of which has a constant width band of the same material on the outer circumference of the ink holding layers 41, 42, and 43. A cloth 44 is wound and adhered, and ink can be applied and written on the surface of the belt cloth 44, so ink can be applied to a wide surface.

FIG. 4 is an enlarged and exaggerated representation below. FIG. 4 is a cross-sectional view showing a manufacturing method of the writing unit 3 that can be rotated to perform stippling. After immersing the assembled metal cylinder 13 in which the independent metal ridges 12 are formed in the melted synthetic resin, When pulled up, a film 14 of synthetic resin is formed. Finally, when the metal cylinders 13 and 12 are decomposed and removed by cooling, the synthetic resin film 14 remains as a cylindrical cavity as shown in FIG. When the jig B is held by the jig B and ground to the position of the chain line 10 by grinding with a grinder or the like, the ink outlets 15 are opened in a point-like manner. The cloth is pushed in and connected to the outer peripheries of the ink holding portions 41, 42 and 43. Then, when the cavity film 14 of the synthetic resin cylinder is adhered and fixed with an adhesive so as to hermetically close the outer periphery of the ink holding portion, a plurality of mutually independent projections 14 are randomly arranged from each pointed outlet 15. Ink comes out in dots. Therefore, by rotating the writing unit, stippling becomes possible.

Next, a method of manufacturing a structure in which the ink outlet of the writing section continues in a spiral shape will be illustrated. FIG. 6 is a cross-sectional view. First, a heated metal spiral core 8 is immersed in a melted synthetic resin liquid, and a synthetic resin adheres to the outer surface of the spiral to form a film 9. When it is lifted and cooled, a synthetic resin film 9 is formed. Since the coefficient of thermal expansion of metal is large, the metal core 8 shrinks when cooled and can be easily separated from the synthetic resin layer 9, leaving only the spiral synthetic resin film 9. As a result, a helical cavity of synthetic resin is formed, and an adhesive is applied to this cavity in places to prevent it from disassembling into pieces, and a cylindrical jig B is inserted and held. When it is rotated and ground to the position of the dashed line 10 with a grinder, a synthetic resin film 91 with an open spiral ink outlet 11 is formed. Therefore, the jig B is removed, and finally stuffed with cotton or cloth, impregnated with ink, and pressed against the outer peripheries of the ink holding layers 41, 42, 43 to complete the process. Therefore, the inner diameter of the spiral is slightly larger than the outer circumference of the ink retaining layers 41, 42, 43, and the circular ink retaining portion of FIG. It is the dimension that the outer circumference of 41, 42, 43 is included.
A synthetic resin cylinder is placed over the metal core 8 shown in FIG. In the state where adhesive is applied in places to prevent disassembly into pieces, the jig B is inserted and held, and the spiral point is ground and removed in the same manner as in FIG. can be spirally opened. The same technique can be used to manufacture the stippled structure of FIGS. 4 and 5 in which a plurality of protrusions are randomly arranged.

As described above, when one or more makeup writing parts are formed in a rotatable circular shape, one or more lines can be drawn at once, points can be drawn, surfaces can be painted, or spirally inclined lines can be drawn. can also be drawn. Moreover, since the writing part is formed perpendicular to the handle, the writing part is not hidden by the hand, and the makeup operation can be performed efficiently, easily and stably.
