Description

Nail chip assembly

Technical field

The present invention relates to a nail chip assembly including a plurality of nail chips. The nail tip is affixed to a surface such as a fingernail or a toe

It is what you wear. Food

Background art

In recent years, nail tips have become popular, especially among young women, and have become indispensable for fashion. The nail tip has a curved shape along the nail, and is mounted by placing it on the outer surface of the user's nail and bonding it. It is possible to enjoy the fashion by decorating the outer surface of the nail tip.

The shape of each conventional nail chip has a curved shape that follows the outer surface of the user's nail and is bonded to the outer surface of the user's nail. However, conventional nail tips are not manufactured by extruding each piece individually, but a plurality of nail tips are formed in the form of a nail tip assembly as shown in Fig. 14 in the manufacturing process. Manufacture together. This nail chip assembly is manufactured by extrusion using a mold. As shown in FIG. 14, the conventional nail chip assembly 100 has a bowl-like structure having a plurality of nail chips 10 1, a shaft body 1 0 2, and a bridge portion 1 0 3. The shaft body 10 2 and the bridge section 1 0 3 are paths for the material that flows into the mold during extrusion, and in principle have no further meaning (Patent Document 1: Japanese Patent Application Laid-Open No. 2). 0 0 5— 3 4 9 1 8 3 Publication, Patent Document 2: Japan (Japanese Laid-Open Patent Publication No. 2 0 06-1 4 1 9 3 9).

In the conventional nail chip manufacturing, the nail chip 1001 is manufactured by separating the nail chips 1001 one by one from the nail chip assembly 100 shown in FIG. Basically, sales of nail chips 10 1 are also separated.

In some cases, the nail chip assembly 100 as shown in FIG. In this way, when the nail chip assembly 100 is sold as it is, it is necessary for the purchaser himself to cut it with a scissors cutter to make one nail chip 1001 one by one.

Conventional nail chips 1 0 1 are basically processed by a user after purchasing them, and then they are subjected to a decoration process such as painting a stone on the outer surface. Take it. Also, it is necessary to go through a drying process such as painting adhesives for stones. Therefore, after temporarily fixing the nail chip 10 0 1 to a work table such as a nail chip stand, the outer surface of the nail chip 1 0 1 was decorated or dried (Patent Document 3). : Japanese Laid-Open Patent Publication No. 2 0 2003-2 3 5 6 3 4, Patent Document 4: Japanese Laid-Open Publication No. 2 0 04-3 1 3 6 34 Publication). In addition, conventional nail tips were manufactured from ABS resin material that can be molded to have similar hardness in order to mimic the hardness and texture of actual human nails. ABS resin is a copolymerized synthetic resin of acrylonitrile, butadiene (Butadiene), and styrene (Styrene). It has excellent mechanical properties such as rigidity, hardness, workability, impact resistance, and bending fatigue, and is thin. It is considered as a material that has good moldability. When molded with ABS resin, the hardness and texture of the nail tip is similar to the hardness and texture of the actual human nails.

Taking nail tips molded from ABS material into your nails It can be seen that close hardness and texture are obtained. As long as it is a false nail that imitates an actual nail, the emphasis was on having hardness and texture similar to those of an actual human nail.

Problems to be solved by the invention

The first problem with conventional nail tips is that the decoration process of the nail tip and the fixing work in the drying process are troublesome.

It was very cumbersome and troublesome to temporarily fix the nail tips one by one on a work table such as a nail tip stand for the decoration process and the drying process. For example, a double-sided tape for nail was placed on the back of the nail chip, and it was temporarily fixed by sticking it to the chip stand.

Even if the conventional nail chip assembly 1 0 0 shown in Fig. 4 is sold and purchased, the nail chip 1 0 1 is cut off from the nail chip assembly 1 0 0 before the nail It was similar in that it was temporarily fixed on a workbench such as a chip stand and the nail chip 10 1 was subjected to a decoration process and a drying process.

Here, it is assumed that the nail chip 1001 is subjected to a decoration process and a drying process without being separated from the conventional nail chip assembly 100, and the nail chip 1001 is separated from the shaft body 1002 after drying. As you can see, there is still a need for some nail tip stand to lift the nail tip. Karu. This is because the conventional nail chip assembly 10 0 0 does not have a self-supporting structure. If it is placed on a desk or the like, the nail chip 1 0 1, the shaft 1 0 2, and the bridge section 1 0 3 It only lies in contact with the desk. Considering the decoration process on the periphery of the nail chip and the overall drying process, the nail chip 1 0 1 is not cut off from the nail chip assembly 1 0 0 but is placed in the shape of the nail chip assembly 1 0 0. It is unsuitable for performing the decoration process and the drying process in the laid state. For this reason, some nail tip stand is required to make the nail tip 10 1 float in the air. Thus, the necessity of a special nail tip stand reduces the convenience for the user and places an additional burden on the purchase of the nail tip stand.

Next, the problem with conventional nail tips using ABS materials was that they were easily broken and weak against bending, so-called “whitening phenomenon” occurred. Fig. 14 Conventional nail tip assembly shown in Fig. 4 is sold as it is, and when it is purchased, when the nail tip 1 0 1 is separated from the shaft 1 0 2 ”Or“ whitening phenomenon ”may occur.

In addition, there is a known problem that, during use, a phenomenon that the nail is broken frequently occurs when it hits the nail or is pressed from above. The occurrence of such “cracking” not only damages the nail tip, but also may damage the user's nails themselves. There is also a known problem that a so-called “whitening phenomenon” occurs in which a crease is formed even if it does not break and the crease part turns white. When whitening occurs, it is no longer used for decoration.

In view of the above problems, the present invention eliminates the need for fixing work in the decoration process and drying process of the nail chip, and is useful when the nail chip is separated or used. It is an object of the present invention to provide a nail chip assembly that does not crack and cause whitening. Means for solving the problem

To achieve the above object, the first nail chip assembly of the present invention has a plurality of nail chips that have a curved shape along the nail and adhere to the outer surface of the user's nail,

A shaft body that is stable and self-supporting in a basic position lying down and that serves as a foundation to support the whole, and is provided laterally with respect to the axial direction of the shaft body at an appropriate interval corresponding to each nail chip A bridge portion connecting the shaft body and the nail tip;

The bridge portion is provided obliquely upward from the shaft body to the nail tip, the nail tip is maintained above the shaft body in the basic posture, and the nail tip is in contact with the bridge portion in the basic posture. It is supported through contact points only and is maintained in the air.

To achieve the above object, the second nail chip assembly of the present invention comprises a plurality of nail chips that have a curved shape along the nail and adhere to the outer surface of the user's nail.

The height from the bridge portion to the bottom surface of the shaft body is sufficiently larger than the thickness of the nail tip, and in the basic posture, the nail tip is supported only through the contact point with the bridge portion and is maintained in the air. It is characterized by that. With the above configuration, the nail tip assembly is self-supporting and stable, and in the self-supporting stable state, the nail tip is maintained in the air only through the contact with the bridge portion, so that the decoration process on the periphery of the nail tip can be easily performed. The drying process is easy to apply.

In the nail chip assembly configured as described above, the size of each nail chip varies from a large size for the thumb to a small size for the little finger,

In the arrangement of the individual nail tips with respect to the shaft body, the nail chips are arranged in order of size from one of the shaft bodies to the other in the order of size,

It is preferable that the thickness of the shaft body and the thickness of the bridge portion are adjusted so as to decrease from one side of the shaft body to the other.

With the above configuration, the amount of material required for the shaft can be reduced. The direction in which the material flows during extrusion is not particularly limited, and the material may be poured from one end of the shaft, the material may be poured from the other end, or from the middle of the shaft. The material may be poured. Adjustments should be made during the manufacturing process taking into account the relationship between the mold and injection speed.

In the above configuration, the adjustment of the thickness of the shaft body includes adjustment of not only the horizontal width of the shaft body but also the height in the vertical direction, and the adjustment of the height of the shaft body includes the shaft Adjustment by raising the bottom of the shaft instead of lowering the top of the body,

A plurality of columnar protrusions corresponding to the height required for the adjustment are provided on the bottom surface of the shaft body portion that has been adjusted to raise the bottom surface,

It is preferable that the entire structure is easily self-supporting and stable due to the bottom surface of the shaft body that has not been adjusted to raise the bottom surface and the bottom surface of the columnar protrusion. With the above configuration, even when the thickness of the shaft body is adjusted, a stable and independent state can be obtained in the basic posture placed on a desk or the like. Next, it is preferable to devise a material for the nail tip. The material of the nail tip is made of a soft resin, and the nail tip having a curved shape along the nail should ensure flexibility that does not cause a whitening phenomenon even if it is pushed in by 3 mm or more from above with the outer surface facing up. preferable.

As the soft resin, for example, an elastomer, a chlorinated resin, and even a new material developed in the future can be applied as long as the hardness is similar to that of an elastomer or a vinyl chloride resin.

With the above configuration, even when the nail tip is separated from the shaft body with a scissors or the like, the nail tip will not break or cause a whitening phenomenon. The nail tip will not break or cause whitening even if it is hit or pressed. Brief Description of Drawings

Hereinafter, embodiments of the nail chip assembly of the present invention will be described with reference to the drawings. However, it goes without saying that the scope of the present invention is not limited to the specific application, shape, number and the like shown in the following examples.

(Example 1)

1 shows a configuration example of a nail chip assembly according to the first embodiment of the present invention.

FIG. 1 is a diagram illustrating a configuration example of a nail chip assembly 10 according to the first embodiment of the present invention.

Figure 1 (a) is a plan view, Figure 1 (b) is a front view, and Figure 1 (c) is a right side view. The nail chip assembly 10 includes a plurality of nail chips 11, a shaft body 12, and a bridge portion _13, and is integrally formed by extrusion molding.

The nail tip 11 has a curved shape along the nail. The size of individual nail tips 1 1 varies from a large size for the thumb to a small size for the little finger.

The shaft body 1 2 has a flat bottom, and is a foundation that supports the entire body in a stable and self-supporting position.

The bridge portion 1 3 is provided laterally with respect to the axial direction of the shaft body 1 2 with an appropriate interval corresponding to each nail chip 1 1, and the shaft body 1 2 and the nail chip 1 1 It plays the role of connecting.

Here, as shown in FIGS. 1 (b) and 1 (c), the bridge portion 13 is provided obliquely upward from the shaft body 12 to the nail tip 11. The reason why the bridge portion 13 is configured diagonally upward in this way is that the nail tip 11 is located above the shaft body 1 2 in the basic posture where the nail tip assembly 10 is placed on a desk or the like. This is to keep the nail tip 1 1 from floating in the air only through the contact point with the bridge 1 2.

For comparison, Fig. 2 is a diagram of a configuration example assuming that the bridge section 12 is provided horizontally from the shaft body 12. Fig. 2 (a) is a plan view, Fig. 2 (b) is a front view, and Fig. 2 (c) is a right side view. Since the shaft body 1 2, the bridge section 1 3 and the nail chip 1 1 are provided in substantially the same plane, when the entire nail chip assembly 1 0 is placed on a desk or the like, FIG. 2 (b), FIG. As shown in 2 (c), the nail tip 11 also touches the desk. If the nail tip 1 1 touches the desk in this way, the decoration on the periphery of the nail tip 1 1 becomes difficult to apply, which is inconvenient for the decoration process, and the painting paint is dried and the stone adhesive is dried. It becomes difficult to remove and is inconvenient for the drying process. As shown in Fig. 1 (b) and Fig. 1 (c), if the bridge portion 13 is configured obliquely upward, the nail tip 1 1 is maintained above the shaft body 1 2 and the nail tip 1 1 is kept floating in the air only through the contact point with the bridge 1 2, making it easy to decorate the periphery of the nail tip 1 1, which is convenient for the decoration process, and drying the painting coating The drying of the glue of the stone and the stone is smooth and convenient for the drying process.

(Example 2)

2 shows a configuration example of a nail chip assembly according to the second embodiment of the present invention.

FIG. 3 is a diagram illustrating a configuration example of the nail chip assembly 10 a according to the second embodiment of the present invention.

Fig. 3 (a) is a plan view, Fig. 3 (b) is a front view, and Fig. 3 (c) is a right side view.

The nail chip assembly 10 a includes a plurality of nail chips 11, a shaft body 1 2 a, and a bridge portion 13. The nail chip 11 may be the same as the nail chip 11 of the first embodiment, and a description thereof is omitted here.

The bridge portion 1 3 a is horizontally provided laterally with respect to the axial direction of the shaft body, and is not lifted obliquely upward as in the first embodiment. However, the thickness of the shaft body 1 2 a is thicker than that of Example 1, and the height from the bridge portion 1 3 a to the bottom surface of the shaft body 1 2 a is sufficiently larger than the thickness of the nail tip 11. It has become a big thing. The shaft body 1 2 a is sufficiently thick so that the nail tip 1 1 is supported in the basic position only through the contact point with the bridge part 1 3 a and is maintained in the air as in Example 1. It is.

(Example 3)

3 shows a configuration example of a nail chip assembly according to the third embodiment of the present invention.

The nail tip assembly of the present invention is supported in a basic posture only through the contact point with the bridge portion and is stable and independent while being maintained in the air. However, it is possible to devise a method to increase the bottom area of the shaft so that it can be more stable and independent.

FIG. 4 is a diagram illustrating a configuration example of the nail chip assembly 10 b according to the third embodiment of the present invention.

Fig. 4 (a) is a plan view, Fig. 4 (b) is a front view, and Fig. 4 (c) is a right side view.

The nail chip assembly 10 b includes a plurality of nail chips 11, a shaft body 1 2, and a bridge portion 1 3 a. The nail chip 11 may be the same as the nail chip 11 of the first embodiment, and a description thereof is omitted here.

The device for increasing the bottom area of the shaft body of the present invention can be either the configuration of the first embodiment or the configuration of the second embodiment. Here, in the configuration of the second embodiment, the bottom area of the shaft body 1 2 b An example was given to increase the value of.

As shown in FIG. 4, the bottom portion of the shaft body 1 2 b is enlarged, and the entire nail chip assembly 1 0 b has a structure that is more stable and independent.

(Example 4)

Describes how to arrange the nail tips 1 1. The following device can be applied to any of the configurations of the first embodiment, the second embodiment, and the third embodiment.

The first device is a device in which a set of nail tips 11 is provided in the control system around the shaft body 1 2. This is to facilitate balancing so that the entire nail chip assembly is stable and independent as will be described later. In the configuration example of FIG. 1 shown in Example 1 and the like, the nail tips 1 1 are provided on both sides of the shaft body from the same location, but approximately the same number of nail tips are provided on both sides of the shaft body.

1 If 1 is present, the weight will be balanced, so it is not always necessary to provide the two sides of the control from the same location. For example, as shown in a nail chip assembly 1 0 c in FIG. 5, the nail tip 1 1 is intersected with the shaft body 1 2 c. They may be provided with each other.

The second contrivance is to reduce the volume of the shaft body 12 and the bridge part 13 and reduce the amount of material poured in the extrusion.

First, the thickness of the shaft 12 and the thickness of the bridge portion 13 may be determined according to the size of the nail tip 11. In other words, the shaft body 1 2 that supports the large-sized nail tip 1 1 for the thumb and the bridge portion 1 3 need to be relatively thick, while the shaft body 1 that supports the small-sized nail tip 1 1 for the little finger 2 and bridge parts 1 3 may be relatively thin.

Next, in the arrangement of the individual nail tips 1 1 with respect to the shaft body 1 2, the arrangement of the shaft body 1 2 from one end 1 2 1 to the other end 1 2 2 is arranged in order of size from the largest to the smallest. The shaft body 1 2 is devised so that one end 1 2 1 side is thicker and the other end 1 2 2 side is thinner. By arranging them in order of size in this way, it is easy to adjust the thickness of the shafts 12 and bridge parts 13.

The width of shaft body 1 2 in the horizontal direction can be adjusted by adjusting the thickness of shaft body 1 2 in an effort to reduce the thickness of shaft body 1 2 toward the other end 1 2 2 side. It is possible to include not only vertical height adjustment. This is because the amount of material can be further reduced by reducing the width in the horizontal direction and the height in the vertical direction.

Here, the height of the shaft body 12 is preferably adjusted by raising the bottom surface of the shaft body 12 instead of lowering the upper surface of the shaft body 12. Fig. 6 (a) is a side view showing the case where adjustment is performed by raising the bottom surface of the shaft body 12 d, while Fig. 6 (b) is the case where adjustment is performed by lowering the top surface of the shaft body 12 e. FIG. As shown in Fig. 6 (a) and Fig. 6 (b), assuming that the bridge part 13 is at the same angle, adjustment by lowering the upper surface of the shaft body 12 d as shown in Fig. 6 (b) If you do nail tips 1 2 is positioned relatively close to the bottom surface, but as shown in Fig. 6 (a), when adjustment is performed by raising the bottom surface of the shaft body 1 2 e, the nail tip 11 is positioned relatively high. Therefore, it is possible to obtain an effect that it is easy to apply decoration in the decoration process and easy to dry in the drying process. The direction in which the material flows during extrusion is not particularly limited, and the material may be poured from one end of the shaft, the material may be poured from the other end, or from the middle of the shaft. The material may be poured. Adjustments should be made during the manufacturing process taking into account the relationship between the mold and injection speed.

Next, the third device is that a plurality of columnar protrusions corresponding to the height required for adjustment are formed on the bottom surface of the shaft body part that has been adjusted to raise the bottom surface of the shaft body 12 e in the second device described above. It is a device to provide. When adjustment is made to raise the bottom surface of the shaft body 1 2 e in the second device above, the bottom surface of the shaft body 1 2 e rises as shown in the side view of Fig. 7 (a). And cannot be stable and independent. Therefore, as shown in the side view of FIG. 7 (b), a plurality of columnar protrusions 14 corresponding to the height required for adjustment are formed on the bottom surface of the shaft body portion that has been adjusted to raise the bottom surface of the shaft body 12 2f. Provide one. By providing the columnar protrusions 14 in this way, the bottom surface of the shaft body 1 2 e, which was not adjusted to raise the bottom surface, and the bottom surface of the columnar protrusions 14 formed the same plane, and the whole was self-supporting. The structure is easy to stabilize.

The structural device of the nail chip assembly 10 of the present invention has been described, but the material device will be described.

The nail chip assembly 10 of the present invention is formed using a soft resin as a material. If the material with a thin wall like nail tip 1 1 is made of a hard material like ABS, when the nail tip 1 0 1 is cut from the shaft 1 0 2, a “crack” will occur or a “whitening phenomenon” may occur. Or it might happen is there.

As a result of the applicant's research, in the nail tip 1 1 having a shape along the nail of the human body, where the peak for the thumb is the highest, the size of the deformation when the nail tip 1 1 is separated, the nail tip 1 Considering the size of the bend applied to a user wearing 1 1 1 Considering the size of the bend applied to 1 1, flexibility that does not cause whitening even if the outer surface is pushed upward 3 mm or more from above It turned out that it was necessary to secure. '

Examples of soft resins include elastomers and bull chloride. Of course, even new materials that will be developed in the future can be applied as long as their hardness is similar to that of elastomer or vinyl chloride resin.

As a result of repeated verification by the applicant, if elastomer or vinyl chloride is used as a soft resin, it is difficult to cause a so-called “whitening phenomenon” even if it is pushed 3 mm or more from the top with the outer surface facing upward and it is difficult to break or bend. The conclusion is obtained.

Actually, the nail chip assembly 10 was made of multiple materials, and the flexibility of bending was verified.

[Samples made]

Using the same mold, a nail chip assembly 10 of the same shape was made using three types of materials.

Nail chip assembly 1 0 A: A B S resin

Nail chip assembly 10 B: Vinyl chloride

Nail chip assembly 1 0 C: Elastomer

[Test 1] Softness test by indentation

An outline of the test method is shown in FIG. Push down the indenter at a speed of 2 mm / sec. Verify whether whitening or cracking occurs in the process. Measure the load required to push to the specified depth did.

Sample type used:

ABS plastic nail chip assembly 1 OA thumb nail chip 1 1 A Vinyl chloride nail chip assembly 1 0 B thumb nail chip 1 1 B Elastomer nail chip assembly 1 0 C nail chip for thumb 1 1 C Equipment: TA.TX'plus Texture AnalyzerJ made by Stable Micro Systems

Test contractor: Japan Hyogo Prefectural Industrial Technology Center

Figure 9 shows the experimental results. As can be seen from the experimental results, it has been verified that the whitening phenomenon does not occur in the A B S resin material nail chip 1 1 A when it is pushed in by 2 mm, but by 3 mm. It was verified that the vinyl chloride material nail chip 11 B and the elastomer material nail chip 11 C did not cause whitening even after 4 mm indentation. Even looking at the load required for indentation, it was verified that the flexibility of the vinyl chloride nail tip 11 B and the elastomer nail tip 11 C was excellent.

[Test 2] Adjustment by spring type hardness tester

The superiority or inferiority of the flexibility of the three types of materials has been verified by Test 1, but since the testing method for the flexibility of plastic materials is determined by the JIS standard, a hardness test was also conducted in accordance with the standard.

The test was conducted according to JIS standard K 7 2 1 5 “Plastic Durometer Hardness Test Method”. An outline of the plastic durometer hardness test method is shown in FIG.

The durometer hardness is a value obtained by applying a test load that changes in accordance with the indentation depth to the sample using an indenter and generating the indentation depth h. There are two types of durometer hardness measurement, Type A and Type D. It is preferable to switch to type D when the measured value is 90 or more when measured with a type A du mouth meter, and type when the measured value is 20 or less when measured with a type D durometer. It is preferable to use A durometer. In this test, the measurement was possible with a Type D durometer, so it was measured with a Type D durometer.

Test sample: Since the material used in the plastic durometer hardness test method must be made of a material with a thickness of 6 mm or more, a set of nail chips molded from ABS resin, vinyl chloride resin, and elastomer materials. Measurements were made using the body shaft.

Test contractor: Hyogo Prefectural Industrial Technology Center

The experimental results are shown in Fig. 11. As can be seen from the experimental results, it was verified that the ABS resin material was the hardest and that vinyl chloride and elastomer were relatively soft.

Considering Experiment 1 and Experiment 2 together, the hardness of the material itself from Experiment 2 increases in the order of elastomer, vinyl chloride, and ABS resin. It was found that if 3 mm indentation was performed, cracking and whitening did not occur with elastomer and vinyl chloride, but cracking and whitening occurred with ABS resin. Next, verify the transparency of the material.

Since the nail tip 11 is decorated, it is preferable that the nail tip 11 has no base color. The actual human nails are also highly transparent. The transmittance was calculated by irradiating light of 3 0 nm to 80 0 η m belonging to visible light. The higher the transmittance, the higher the transparency.

Fig. 12 (a) shows the transparency of ABS resin, Fig. 12 (b) shows the transparency of butyl chloride, and Fig. 13 shows the transparency of the elastomer.

As shown in Fig.12 and Fig.13, ABS resin and vinyl chloride are roughly 80% It can be said that the transmittance is about 90%. When viewed, the elastomer appears to be the clearest and most transparent. From the viewpoint of transparency, the elastomer is a suitable material for nail chips.

From the results of Experiment 1, Experiment 2, and Experiment 3, it was concluded that elastomer and bull chloride resin are suitable as nail chip materials.

As described above, through the verification experiment, the applicant has concluded that it is suitable to use elastomer and bichloride as the material for the nail chip assembly of the present invention.

Although the preferred embodiments of the present invention have been illustrated and described above, it will be understood that various modifications can be made without departing from the technical scope of the present invention. Therefore, the technical scope of the present invention is limited only by the description of the appended claims.
