Description

[Technical Field]

[0001] The present invention relates to a hair liquid applicator. [Background technology]

[0002] 2. Description of the Related Art A hair-augmenting method is known in which artificial hair or human hair is attached to natural hair to increase hair volume. A known method for attaching artificial hair or human hair to natural hair is to use an adhesive, for example.

[0003] Patent Document 1 discloses an adhesive applicator for bonding artificial or human hair to natural hair using a liquid adhesive. This adhesive applicator includes a first adhesive holding member, a second adhesive holding member positioned away from the first adhesive holding member, and a connecting portion connecting the base end of the first adhesive holding member to the base end of the second adhesive holding member. Furthermore, this adhesive applicator is capable of inserting natural and artificial hair or human hair into the gap between the first and second adhesive holding members. Patent Document 1 claims that it is easier than ever to bond natural and artificial hair. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] Japanese Patent Application Laid-Open No. 2025-109604 Summary of the Invention [Problem to be solved by the invention]

[0005] However, in Patent Document 1, it is necessary to apply liquid adhesive to the first adhesive holding member and the second adhesive holding member, which is time-consuming and reduces efficiency. Furthermore, the liquid adhesive must be manually supplied from a separate location, which is time-consuming and has the problem of not being able to be used continuously. For this reason, Patent Document 1 calls for improving efficiency. For the purpose of applying adhesive to hair, it is difficult to adopt the configuration of a conventional adhesive applicator that is different from this purpose. For these reasons, further improvements are needed in the technology for applying adhesive to hair, such as improvements in work efficiency and applicability.

[0006] Furthermore, hair augmentation methods include not only bonding artificial hair or human hair to natural hair, but also tying artificial hair to natural hair. In this method, a knot in the artificial hair is formed near the root of the natural hair. To make this knot less noticeable, methods such as making the artificial hair transparent are known. In this method, the knot becomes more noticeable as the natural hair grows, and there has been a demand for coloring to make the knot less noticeable. However, general coloring tools have difficulty capturing fine hairs, making it difficult to properly color the artificial hair and its knots. Therefore, there has been a demand for a technology that can color hair efficiently and effectively.

[0007] Therefore, an object of the present invention is to provide a liquid agent applicator for hair that can efficiently and effectively apply a liquid agent to hair. [Means for solving the problem]

[0008] In order to solve the above problems, the hair liquid agent applicator of the present invention is a pen-shaped hair liquid agent applicator for applying a liquid agent to hair, which has a pen body and a pen tip, and is of a size and weight that can be held in one hand, the hair being natural hair, artificial hair attached to natural hair, artificial hair to be attached to natural hair, or human hair or artificial hair attached to a wig, the pen body containing the liquid agent, the liquid agent contained in the pen body moving to the pen tip and applied from the pen tip, and the pen tip having any of the following shapes: a shape with a notch, a shape with a slit, or a shape with the end of the slit widened. [Effects of the Invention]

[0009] According to the present invention, it is possible to provide a liquid agent applicator for hair that can efficiently and effectively apply a liquid agent to hair. [Brief explanation of the drawings]

[0011] The hair liquid agent applicator according to the present invention will be described below with reference to the drawings. The present invention is not limited to the following embodiments, and can be modified, added, modified, deleted, or otherwise altered within the scope of what one skilled in the art can conceive. Any embodiment that achieves the functions and effects of the present invention is within the scope of the present invention.

[0012] <Overview of hair liquid applicator> The hair liquid agent applicator of the present invention is a pen-shaped hair liquid agent applicator for applying a liquid agent to hair, and has a pen body and a pen tip, and is of a size and weight that can be held in one hand. The hair is natural hair, artificial hair attached to natural hair, artificial hair to be attached to natural hair, or human hair or artificial hair attached to a wig. The pen body contains the liquid agent, and the liquid agent contained in the pen body moves to the pen tip and is applied from the pen tip. The pen tip has one of the following shapes: a shape with a notch, a shape with a slit, or a shape with the end of the slit widened. According to the present invention, the liquid agent can be applied to the hair efficiently and effectively.

[0013] FIG. 1 shows an example of the appearance of a liquid hair applicator 1. (A) is a side view. (B) is an example of (A) with a cap 12 attached. Since the liquid hair applicator of the present invention is pen-shaped, the cap 12 may be attached in this manner. Attaching the cap 12 improves portability and ease of handling. Attaching the cap 12 also protects the pen tip 11.

[0014] As shown in (A), the hair liquid applicator of the present invention has a pen body 10 and a pen tip 11. The pen body 10 contains the liquid, which moves to the pen tip 11 and is applied from the pen tip 11. The hair liquid applicator of the present invention is sized and lightweight to be held in one hand. This makes it easy for the operator to hold and use. Furthermore, since there is no need to refill the pen tip with the liquid from a separate source when using the device, it is easy to use, convenient, and improves efficiency.

[0015] The size and weight of the applicator should be such that it can be held in one hand, assuming that the user is an average adult. The user can work on their own natural hair or artificial hair attached to natural hair, or someone else can do the work. When working with the applicator, it is easy and convenient to use because it is large enough to be held in one hand. Even when working with someone else, the hair liquid agent applicator is easy and convenient to handle. The term "apply" includes terms such as "to exude," "to apply," and "to paint."

[0016] The pen body contains the liquid agent. The liquid agent contained in the pen body moves to the pen tip and is applied from the pen tip. The hair liquid agent applicator of this invention does not require the user to supply the liquid agent to the pen tip when applying the liquid agent. This makes it easy to use whenever desired. It can also be used continuously until the built-in liquid agent runs out. Since there are many hairs, if the liquid agent had to be supplied from an external source, work efficiency would be significantly reduced. Therefore, the present invention allows for continuous use, improving work efficiency.

[0017] The hair to which the liquid agent is applied is selected from natural hair, artificial hair attached to natural hair, artificial hair to be attached to natural hair, and human or artificial hair attached to a wig. The liquid agent may be applied to one strand of hair or to multiple strands at once.

[0018] The artificial hair attached to the natural hair may be in a knotted state or in a glued state. The artificial hair attached to the natural hair may also be in a knotted state. The shape of the pen tip in this device is designed to make it easy to contact and grasp even fine knots, allowing for efficient and effective application of the liquid to, for example, knots in artificial hair.

[0019] The hair liquid agent applicator of the present invention can be used on artificial hair attached to natural hair, or on artificial hair before it is attached to natural hair. The hair liquid agent applicator of the present invention can be held and used in one hand, so it is particularly useful for artificial hair attached to natural hair.

[0020] Human or artificial hair planted in a wig includes human or artificial hair planted in a wig base. The human or artificial hair planted in a wig to which the liquid agent is applied may be in a knotted state or in a non-knotted state. The liquid agent applicator for hair of the present invention may be used with or without a wig attached to the head. The liquid agent applicator for hair of the present invention can be held and used in one hand, making it particularly useful for applying human or artificial hair to a wig attached to the head.

[0021] The pen tip of the present invention has a specially designed shape to effectively apply the liquid agent to hair. It has one of the following shapes: a shape with a notch, a shape with a slit, or a shape with a slit that is widened at the end. These shapes are also referred to as the first, second, and third shapes, respectively. These shapes make it easier for the pen tip to contact and capture even fine hairs. Therefore, when the pen tip is brought into contact with the hair, the hair is guided toward the pen body, and even when the pen body is moved during application of the liquid agent, the hair is less likely to separate from the pen tip. This allows for efficient and effective application of the liquid agent to hair. The example shown in Figure 1(A) has a shape with a notch 21 at the tip, which is V-shaped in side view.

[0022] <Liquid> The liquid agent can be appropriately selected, and examples thereof include colorants, adhesives, molding agents, abrasives, etc. Among these, colorants and adhesives are preferred as liquid agents. The liquid agent applicator for hair of the present invention can effectively color and adhere (or fix) hair due to its pen-shaped usability and the shape and configuration of the pen tip.

[0023] Examples of colorants include ink, oil-based ink, and water-based ink, and considering the purpose of applying it to hair, oil-based ink is preferably used. The colorant may also be called a coloring material. A dye may also be used as the colorant. The color of the colorant is not particularly limited and can be selected appropriately, and examples include black, brown, and gold. The color is selected appropriately taking into consideration the color of natural hair, the color of artificial hair, the color of skin, etc.

[0024] The adhesive can be appropriately selected, and a general adhesive can be used, such as octyl cyanoacrylate. The molding agent can be appropriately selected, and for example, an ultraviolet curable resin, such as an acrylic component, can be used. The abrasive can be selected appropriately, and for example, silicon dioxide can be used.

[0025] The combination of the liquid agent and the hair to which it is applied may be selected appropriately. When the liquid agent is a colorant, the present invention is suitable for applying the liquid agent to artificial hair attached to natural hair or to human or artificial hair attached to a wig. It can be used effectively to color artificial hair attached to natural hair (including artificial hair added to natural hair) or when a wig is worn on the head. However, when applying a colorant, the present invention can also be used effectively to other types of hair, such as artificial hair to be attached to natural hair. As described below, the hair liquid agent applicator of the present invention is suitable for coloring artificial hair attached to natural hair. The hair liquid agent applicator of the present invention is particularly suitable for coloring knotted artificial hair attached to natural hair. The hair liquid agent applicator of the present invention is pen-shaped and can be held in one hand, and the ingenious shape of the pen tip allows for effective and efficient application of colorant to artificial hair attached to natural hair, especially knotted artificial hair.

[0026] When the liquid agent is an adhesive, this device is suitable for applying the liquid agent to at least one of the artificial hair to be attached to natural hair and the natural hair to which the artificial hair is attached. The hair liquid agent applicator of this device is a pen-type that can be held in one hand and has an ingenious pen tip shape that makes it easy to apply the adhesive to the hair. However, when applying the adhesive of this device, it can also be used effectively on other types of hair, such as artificial hair attached to natural hair.

[0027] When using adhesive to attach (or bond) artificial hair to natural hair, there are several methods, such as applying adhesive to the natural hair and then contacting the artificial hair, applying adhesive while the artificial hair is in contact with the natural hair, or applying adhesive to the artificial hair and then contacting the natural hair. The present invention can be used effectively with any of these methods. As will be explained later, for example, the process can be performed efficiently by transferring a liquid agent from the pen body to hold the adhesive in a groove in the pen tip, and then contacting the natural or artificial hair with the held adhesive to apply the adhesive. Furthermore, the present invention makes it easy to apply adhesive around the area where the natural and artificial hairs are to be attached, resulting in good adhesion.

[0028] The liquid agent for hair applicator of the present invention is a coloring agent, and is preferably used for hair thickening purposes, applying the liquid agent to the knots of artificial hair attached to natural hair to color them. The liquid agent for hair applicator of the present invention is a pen-type that can be held in one hand, and the ingenious shape of the pen tip makes it easy to apply the liquid agent to the knots of artificial hair attached to natural hair. Therefore, the liquid agent for hair applicator of the present invention makes it easy to color the knots of artificial hair used for hair thickening purposes, and is ideal for hair thickening purposes.

[0029] In the above case, when the pen tip has the first shape, it is more preferable that the pen tip has a V-shape that widens toward the tip end in side view. That is, it is preferable that the shape of the pen tip has the notch on the tip end side, and that the notch has a single V-shape in side view and is a V-shape that widens toward the tip end of the pen tip. In this case, it is also preferable that the liquid is a colorant, that it is used for hair thickening, and that the liquid is applied to the knot of artificial hair attached to natural hair to color it. In this case, the knot of the artificial hair is guided into a V-shaped groove (which may also be called a valley, bottom, etc.), preventing the knot from coming off the pen tip when the hair liquid applicator is moved during coloring, and allowing the knot to be colored efficiently.

[0030] The viscosity of the liquid is not particularly limited, as long as it can be contained in the pen body, moved from the pen body to the pen tip, and applied from the pen tip. The liquid may be one with high viscosity that remains exposed on the surface of the pen tip, or one with low viscosity that is immersed in the pen tip without being exposed on the surface of the pen tip. If the liquid has a high viscosity, pressure may be applied to the pen body from the outside to move the liquid from the pen body to the pen tip.

[0031] The method for incorporating the liquid agent into the pen body can be selected as appropriate. Examples include a batting type, a direct-fill type, and a cartridge type. Direct-fill types include a valve type and an accordion type. Of these, the batting type, valve type, and cartridge type are preferred. These methods allow the liquid agent to be incorporated into the pen body, and have advantages such as being usable for hair applications and being easily available. The method for incorporating the liquid agent into the pen body can be selected as appropriate depending on the type of liquid agent, the application of the liquid agent for hair applicator, the type of hair, etc.

[0032] Figure 2 is a cross-sectional schematic diagram for explaining an example of a fill type. Fill 13 containing a liquid agent is provided in the pen body. Pen tip 11 is provided so as to be in contact with fill 13. The liquid agent moves from fill 13 to pen tip 11 by capillary action, and the liquid agent is applied from pen tip 11.

[0033] When the liquid is a colorant, a pad-type pen is preferable. When the liquid is a colorant, a pad containing the colorant is provided inside the pen body, and the colorant is supplied from the pad to the pen tip. In this case, the liquid can be applied smoothly. Furthermore, the liquid can be applied from the pen tip without having to apply pressure to the pen body, making it easy to use.

[0034] In the direct fill type, the liquid is filled directly inside the housing of the pen body. In the direct fill type, a stirring member may be provided at the location where the liquid is filled. By repeatedly shaking the pen body in the longitudinal direction, the stirring member moves, allowing the components of the liquid to be stirred uniformly.

[0035] FIG. 3 is a diagram for schematically explaining an example of a valve type. The valve type is one of the direct liquid types. In the valve type, a valve 16 is provided between the pen tip and the liquid agent contained in the pen body. By pressing the pen tip 11 toward the pen body, the opening 17 of the valve 16 opens, and the liquid agent moves to the pen tip 11. When the liquid agent has a high viscosity, it is preferable to use the valve type.

[0036] FIG. 4 is a diagram for schematically explaining an example of a cartridge-type pen. (A) is a diagram showing a schematic view from an oblique direction, and (B) is a diagram showing a schematic cross section. The pen body 10 is equipped with a cartridge 19, and the inside of the cartridge 19 is filled with a liquid agent. The pen tip 11 and the liquid agent inside the cartridge 19 are connected by a relay core 18. This allows the liquid agent inside the cartridge 19 to move to the pen tip 11 through the relay core 18. When the liquid agent in the cartridge 19 runs out, the cartridge 19 can be removed and a new cartridge 19 can be installed. In this way, the pen tip 11 can be continued to be used.

[0037] In the cartridge type, for example, a cartridge is attached inside the housing of the pen body. In this case, it can be said that the liquid agent is built into the pen body. In addition to this, the cartridge type may also be configured such that the entire housing of the pen body is attached as a cartridge. Even in this case, it is still considered to be included in the category of pens in which the liquid agent is built into the pen body.

[0038] <Pen tip shape> The pen tip of the present invention has a specially designed shape to ensure good application of the liquid to the hair, and has one of the following shapes: a shape with a notch (first shape), a shape with a slit (second shape), or a shape with the end of the slit widened (third shape). By doing so, when the pen tip is brought into contact with the hair, the hair is guided toward the pen body, and even if the pen body is moved when applying the liquid, the hair is less likely to separate from the pen tip. Therefore, the liquid can be applied to the hair well. The notch may also be referred to as a concave shape.

[0039] The pen tip preferably has a shape with one notch at the tip. When the pen tip has one notch, it is easier to bring the pen tip into contact with the target hair compared to when the pen tip has multiple notches. This reduces the application of the liquid agent to hair other than the target hair. For example, when applying adhesive, the adhesive can be applied precisely to the hair to which it is to be attached, resulting in better adhesion (bonding).

[0040] The shape of the notch can be selected as appropriate, and examples thereof include a V-shape, a U-shape, and a rectangular shape. Among these, it is preferable that the notch be V-shaped in side view. This allows the hair to fit into the V-shaped groove, making it less likely for the hair to come off the pen tip even when the pen body is moved during application of the liquid. This shape allows for better application of the liquid to fine hairs.

[0041] The notch or cut is preferably located on the tip side of the pen tip. When it is located on the tip side, it becomes easier for the pen tip to come into contact with the target hair. Also, by being located on the tip side, it is possible to reduce a decrease in the durability of the pen tip. The notch or cut may be located on the side of the pen tip.

[0042] Examples of the shape of the pen tip will be described. Figure 5 is a side view of an example of a pen tip. This example is an example in which the pen tip 11 has a first shape, and is an example in which there is one notch 21 on the tip side of the pen tip 11. This example is also an example in which the notch 21 is V-shaped, and is a V-shape that widens toward the tip side of the pen tip in side view. By using such a shape, the hair fits into the V-shaped groove, making it more difficult for the hair to come off the pen tip even when the pen body is moved when applying the liquid agent. The width, depth, etc. of the notch can be selected as appropriate. In this example, the width (W) of the V-shape is, for example, 2.5 mm, and the depth (D) is, for example, 3.0 mm. By using such sizes, it becomes easier to apply the liquid agent to the hair.

[0043] Figure 6 is a side view of another example of the pen tip. Similar to the example shown in Figure 5, this example is an example in which the pen tip 11 has a first shape, and is an example in which there is one notch 21 on the tip side of the pen tip 11. This example is also an example in which the notch 21 is V-shaped, and is a V-shape that widens towards the tip side of the pen tip in side view. This example has a shallower shape than the example shown in Fig. 5. The width (W) of the V-shape in this example is, for example, 1.0 mm, and the depth (D) is, for example, 0.5 mm. Making such a shallow V-shape has the advantage of being easier to process.

[0044] 7 is a side view of another example of the pen tip. This example is an example in which the pen tip 11 has a first shape, and is an example in which there is one notch 21 on the tip side of the pen tip 11. This example is also an example in which the notch 21 is U-shaped, and is a U-shape that widens toward the tip side of the pen tip in side view. Even with such a U-shape, the hair can be guided into the U-shaped groove, and the liquid agent can be applied to the hair well. From the viewpoint of capturing the hair and preventing it from coming off, the V-shape is preferable to the U-shape. The U-shape has the advantage that, for example, the notch can be brought into contact with a knot in the artificial hair, making it easy to move when the pen body is rotated and moved. In this example, the width (W) of the U-shaped bristle is, for example, 2.5 mm, and the depth (D) is, for example, 3.0 mm. By using such dimensions, it becomes easier to apply the liquid agent to the hair.

[0045] Figure 8 is a side view of another example of the pen tip. Similar to the example shown in Figure 7, this example is an example in which the pen tip 11 has a first shape, and is an example in which there is one notch 21 on the tip side of the pen tip 11. This example is also an example in which the notch 21 is U-shaped, and is a U-shape that widens toward the tip side of the pen tip in side view. This example has a shallower shape than the example shown in Fig. 7. The width (W) of the U-shape in this example is, for example, 1.0 mm, and the depth (D) is, for example, 0.5 mm. Making such a shallower U-shape has the advantage of being easier to process.

[0046] 9 is a side view of another example of the pen tip. This example is an example in which the pen tip 11 has the first shape, and is an example in which there is one notch 21 on the tip side of the pen tip 11. This example is also an example in which the notch 21 is rectangular. Even with this type of notch 21, it is possible to guide the hair into the groove of the notch, and the liquid agent can be applied to the hair well. The width (W) of the notch 21 in this example is, for example, 0.5 mm, and the depth (D) is, for example, 0.5 mm.

[0047] FIG. 10 is a side view of another example of the pen tip. This example is an example in which the pen tip 11 has a first shape and has one notch 21 on the tip side of the pen tip 11. This example is also an example in which the notch 21 is V-shaped. This example is a modified V-shape and is an example in which the V-shape does not widen toward the tip side of the pen tip in side view. Even with a V-shape like this example, hair can be guided into the V-shaped groove, allowing the liquid to be applied to the hair well. The V-shaped examples shown in FIGS. 5 and 6 make it easier to bring the V-shaped groove into contact with the hair than this example.

[0048] FIG. 11 is a side view of another example of the pen tip. This example is an example in which the pen tip 11 has a first shape and has one notch 21 on the tip side of the pen tip 11. This example is also an example in which the notch 21 is V-shaped. This example is a modified V-shape and is an example in which two small hills are formed on both sides of the V-shaped groove. Even with a V-shape like this example, hair can be guided into the V-shaped groove, allowing the liquid to be applied to the hair well. However, when the pen tip is brought into contact with hair, the hair may flow along the small hills and move to the side of the pen tip, so the V-shaped grooves shown in FIGS. 5 and 6 are easier to bring into contact with the hair than this example.

[0049] FIG. 12 is a diagram for schematically explaining another example of the pen tip. This example is an example in which the pen tip 11 has a second shape. The second shape is a shape with a slit 22. By passing the hair through the inside of the slit, the liquid agent can be applied to the hair satisfactorily. By passing the hair through the inside of the slit and moving the pen body, for example, in an up-and-down direction (for example, in the direction of hair growth), the liquid agent can be applied to the hair satisfactorily.

[0050] The shape of the slit can be selected as appropriate, as long as it is a slit that allows the hair to be passed through in the direction toward the inside of the pen tip. The number of hairs to be passed through in the direction toward the inside of the slit can be selected as appropriate, and may be one or more. The method for forming the shape with the slit (second shape) can be selected as appropriate, and examples include a method of cutting a slit into the pen tip with a cutter or the like. The depth of the slit can be selected as appropriate.

[0051] The second shape, a notch, can be determined to have a notch shape if a hair can be passed through the pen tip toward the inside, even if it is not visible to the naked eye. The method for distinguishing between a notch (first shape), such as the notch shown in FIG. 9, and a shape having a notch (second shape) can be selected as appropriate, and a threshold value can be set based on the width, for example. Alternatively, for example, a shape that can be seen from the side can be determined to be the first shape, and a shape that cannot be seen to be the second shape.

[0052] FIG. 13 is a diagram for schematically explaining another example of the pen tip. (A) is a perspective view, and (B) is a side view. This example is an example in which the pen tip 11 has a third shape. The third shape is a shape 23 in which the end of the slit is widened. The slit in the third shape may be referred to as a slit portion. The widened end of the slit may be referred to as an opening. The opening may be referred to as a liquid reservoir portion.

[0053] The third shape shown in the figure has a slit 24 and an opening 25 that is connected to the slit 24, penetrates one side surface of the pen tip from the opposite side surface, and is wider than the slit 24 in side view. As shown in the figure, the width w2 of the opening 25 is wider than the width w1 of the slit 24. The shape in which the end of the slit is widened is a shape consisting of the slit (slit 24) and a portion (opening 25) at the end of the slit (inside the pen tip) that is wider than the width of the slit.

[0054] The third shape allows the hair to pass through the slit 24 (slit) and reach the opening 25, allowing the liquid to be applied efficiently at the opening 25. The hair inserted into the opening 25 is less likely to escape from the pen tip even when the pen body is moved, so the pen body can be moved quickly, improving workability.

[0055] The width w2 of the opening 25 may be set to the maximum width of the opening 25. When the opening 25 is circular in side view, the width w2 of the opening 25 may be set to, for example, the diameter of the circle. The opening 25 serves as a space in which the liquid agent can be stored. The opening 25 may also be referred to as a liquid reservoir, etc. It is preferable that the opening 25 has a circular shape as shown in the drawing in side view. Having a circular shape reduces damage to hair. The opening 25 may have a shape other than a circular shape in side view.

[0056] In the third shape, the width (w1) of the slit 24 is, for example, 0.5 mm, and the width (w2) of the opening 25 is, for example, 2 mm in diameter. Such sizes make it easier to apply the liquid agent to the hair. The width (w1) of the slit 24 may be 0.5 mm or less, as long as it is large enough for the hair to pass through.

[0057] FIG. 13(C) is a diagram for schematically illustrating an example in which the liquid agent 14 is stored in the opening 25 (liquid reservoir). As shown in the figure, the liquid agent 14 can be stored in the liquid reservoir, and the stored liquid agent can be applied well by contacting the hair. For example, such an application method may be used when the viscosity of the liquid agent is high. However, in the third shape, it is not necessary to store the liquid agent in the opening 25, and an appropriate application method may be selected.

[0058] The first and second shapes have the advantage of being easier to process than the third shape. The third shape has the advantage of being less likely to catch and release hair than the first shape. Furthermore, the third shape also allows for an application method in which the liquid agent is stored in the opening 25 (liquid reservoir) and the stored liquid agent is brought into contact with the hair to apply it, allowing for good application.

[0059] Figures 5 to 13 show examples where a notch or slit is provided on the tip side of the pen tip. By providing a notch or slit on the tip side of the pen tip, it becomes easier for the pen tip to come into contact with the target hair, but this invention is not limited to the tip side. For example, a notch or slit may be provided on the side of the pen tip. When a notch or slit is provided on the tip side of the pen tip, a decrease in durability can be suppressed.

[0060] 14 shows a comparative example not included in the present invention. The pen tip 11a of this comparative example does not have the first, second, or third shape. In this case, when applying the liquid to the hair, the hair moves on the surface of the pen tip, the position of the hair is not fixed, and the liquid cannot be applied properly to the targeted location.

[0061] <Nib material> The material of the pen tip can be selected appropriately. For example, it is preferable to select the material according to the shape of the pen tip, the purpose, and the type of liquid. In addition, the material of the pen tip can be selected taking into consideration the ease of processing the pen tip.

[0062] When used for hair coloring, it is preferable to use, for example, felt (synthetic fiber) as the material for the pen tip. Since the coloring agent used for coloring is, for example, ink or oil-based ink, synthetic fiber such as felt allows the coloring agent to be smoothly applied to the hair. Also, when the purpose is to apply an abrasive to peel off artificial hair, it is preferable to use, for example, felt (synthetic fiber) as the material for the pen tip. In this case, it can be polished well.

[0063] When the pen tip has the third shape and is used for coloring purposes, the material of the pen tip can be not only felt (synthetic fiber) but also alloys such as stainless steel, which make it easier to form and maintain the third shape.

[0064] When used for fixing hair or forming knots, the pen tip material can be, for example, resin, rubber, or metal, such as polyethylene, polypropylene, polyacetal, silicone rubber, aluminum, steel, etc. For example, adhesives used for fixing hair may have a certain degree of viscosity, so using these materials allows for better application of the liquid agent than with synthetic fibers such as felt.

[0065] <Examples of combinations of nib shape, nib material, fluid type, and application> When the pen tip has the first shape and is used for coloring purposes, the material of the pen tip is preferably felt (synthetic fiber), and it is preferable that the colorant is built into the pen body in a padded manner. When the pen tip has the first shape and is used for removing knots, the pen tip is preferably made of felt (synthetic fiber), and it is preferably a direct-flow type pen with an abrasive built into the pen body. When the pen tip has the first shape and is used for fixing hair, the pen tip is preferably made of a material such as resin, rubber, or metal, and is preferably a direct-flow type in which the adhesive is built into the pen body. When the pen tip has the first shape and is used for forming knots, it is preferable to use, for example, resin, rubber, or metal as the material for the pen tip, and it is preferable to use a direct-flow type pen with the forming agent incorporated into the pen body. These configurations are particularly preferable when the pen tip has a V-shape as shown in FIGS. When the pen tip has the second shape, it is preferable to do the same as above. When the pen tip has the third shape, it is substantially the same as above, but when it is used for coloring, the material of the pen tip can be alloy such as stainless steel in addition to felt (synthetic fiber).

[0066] <Application> The hair liquid agent applicator of the present invention is used to apply a liquid agent to hair, and the application of the liquid agent to hair can be selected appropriately. Examples include applications in which a colorant is applied to natural hair, artificial hair attached to natural hair, artificial hair to be attached to natural hair, or human or artificial hair attached to a wig. Examples of artificial hair attached to natural hair include knots in artificial hair and loops formed by artificial hair. Artificial hair in an untied state, such as fixed artificial hair, can also be colored. When coloring artificial hair, the present invention is particularly suitable for coloring knots in artificial hair tied to natural hair. When coloring natural hair, the hair liquid agent applicator of the present invention is particularly suitable for coloring natural hair when the roots of the natural hair have turned gray.

[0067] As mentioned above, the color of the colorant is not particularly limited and can be selected appropriately. The color of the knot of the artificial hair before coloring with the hair liquid applicator of the present invention can be, for example, transparent, light colored, white, etc.

[0068] Other uses for applying a liquid agent to hair include applying and fixing adhesive to natural hair, artificial hair attached to natural hair, artificial hair to be attached to natural hair, or human or artificial hair attached to a wig. Among the uses of the liquid agent applicator for hair of the present invention, coloring and adhesion (fixing) are particularly preferred.

[0069] Another example of a use for applying a liquid agent to hair is to shape the knot of artificial hair tied to natural hair. In the case of shaping, a shaping agent is used as the liquid agent, and after application, the shaping agent is solidified to make the shape smooth. Another example of a use is to apply an abrasive to the knot of artificial hair tied to natural hair and rub it to remove the artificial hair.

[0070] Example 1: Coloring of artificial hair Next, the present invention will be described with reference to the following examples, but the present invention is not limited to the following examples. FIG. 15 is a diagram for explaining Example 1. Example 1 is an example in which the hair liquid agent applicator of the present invention is used for coloring purposes. Example 1 is an example in which a knot of artificial hair attached to natural hair is colored. The example shown in the figure shows a state in which an artificial hair 32 is knotted to a single natural hair 31. A knot 33 is formed in the artificial hair 32. FIG. 15(A) is an enlarged schematic diagram of a main part of the knot 33. The knot 33 is formed by knotting the artificial hair 32 to the natural hair 31.

[0071] When attaching the artificial hair 32 to the natural hair 31, it is preferable to attach it to the roots of the natural hair 31 (close to the scalp). By attaching it to the roots of the natural hair 31, the artificial hair 32 can be used for a longer period of time when the natural hair 31 grows. To attach the artificial hair 32 to the natural hair 31, for example, an operator may knot the artificial hair 32, or a loop or the like may be formed in the artificial hair 32, and the natural hair 31 may be passed through the loop and then the loop may be narrowed to attach the artificial hair 32. In these methods, a knot 33 is formed in the artificial hair 32.

[0072] When attaching the artificial hair 32 to the root of the natural hair 31, it is preferable that the knot 33 located at the root of the natural hair 31 (close to the scalp) is not noticeable, so that the knot 33 is, for example, transparent. To make the knot 33 transparent, for example, the part of the artificial hair 32 that will become the knot 33 is bleached or dyed in advance to a transparent or light color, and the artificial hair 32 is attached to the natural hair 31 so that the transparent part becomes the knot 33. In this way, when the artificial hair 32 is tied to the natural hair 31, the knot 33 is not noticeable, resulting in a natural look.

[0073] On the other hand, as the natural hair 31 grows, the knot 33 moves upward, which is the direction of growth of the natural hair 31. If the knot 33 is transparent, and moves upward, the knot 33 becomes noticeable, for example, when the natural hair 31 is a dark color such as black. Therefore, a hair liquid applicator that can pinpoint color the transparent knot 33 in the artificial hair 32, as in this example, is very useful.

[0074] In this Example 1, the pen tip has a first shape (notch 21), and the notch 21 is V-shaped as shown in Figure 5. In addition, black oil-based ink is used as the liquid agent, and the transparent knot is colored black. In addition, the liquid agent is a padded type and is built into the pen body.

[0075] 15(B) is a schematic diagram illustrating an example of when the pen tip 11 of the hair liquid agent applicator is brought into contact with the knot 33. By bringing the knot 33 into contact with the notch 21 of the pen tip 11 and moving the pen tip 11 in a rotating manner around the knot 33, the knot 33 can be colored efficiently and evenly. The application direction is not limited to this, and may be, for example, the direction in which the natural hair 31 grows, or the liquid agent may be applied by moving the pen tip 11 up and down.

[0076] 15(C) is a diagram for schematically explaining an example of a case where the knot 33 is in contact with the notch 21 of the pen tip 11. The notch 21 of the pen tip 11 is in contact with the knot 33, and the knot 33 comes into contact with the V-shaped groove, making it easier to color the knot 33.

[0077] In the figure, one knot is shown in the V-shape, but the number of knots 33 that are brought into contact with the V-shaped groove when coloring is not particularly limited. It may be one or more. The number of knots 33 that are brought into contact can be appropriately selected depending on the shape of the pen tip. If one knot 33 is brought into contact with the V-shaped groove and a liquid agent is applied to color it, it can be colored evenly. If multiple knots 33 are brought into contact with the V-shaped groove and a liquid agent is applied to color it, multiple knots 33 can be colored simultaneously.

[0078] 15(D) is a diagram showing a schematic diagram of the knot 33 after coloring. As shown in the figure, the previously transparent knot 33 is now colored black. As described above, according to this embodiment, it is possible to efficiently and effectively color knots of hair, for example, artificial hair. Furthermore, the hair liquid agent applicator of this embodiment can be held and used in one hand, and because it is a padded type with a built-in colorant, it is possible to easily and continuously color multiple natural hairs. Note that the figures are for illustrative purposes only and are not to scale. For example, the size ratio between the hair and the liquid hair applicator differs from the actual size. Also, the size ratio between the knot 33 and the V-shape shown in the figures may not be the same as the actual size.

[0079] In this Example 1, a colorant is applied to artificial hair used for hair thickening, and therefore the hair liquid agent applicator in this Example may be referred to as an item used for hair thickening. For example, the hair liquid agent applicator in this Example may be referred to as a hair thickening liquid agent applicator, a hair thickening auxiliary tool, etc.

[0080] <Example 2: Coloring natural hair> Figure 16 is a diagram for explaining Example 2. Example 2 is an example in which the hair liquid agent applicator of the present invention is used for coloring purposes. Example 2 is an example in which a coloring agent is applied as a liquid agent to the roots of natural hair to color it. The hair liquid agent applicator used in this example is the same as that used in Example 1. The example shown in the figure is an example in which the roots of natural hair 31 have become partially gray. (A) schematically shows the roots of natural hair 31 having become partially gray, and (B) schematically shows the natural hair 31 after coloring.

[0081] The pen tip of Example 2 has a V-shape, making it easy to apply colorant to natural hair. The hair comes into contact with the V-shaped groove, and the natural hair is less likely to slip out of the V-shaped groove even when the pen body is moved. This allows the roots of natural hair to be colored well. Furthermore, the hair liquid applicator of this example can be held and used in one hand, and because it is a padded type with a built-in colorant, it allows for easy and continuous coloring of multiple natural hairs.

[0082] <Example 3: Adhesion> Fig. 17 is a diagram for explaining Example 3. Example 3 is an example of fixing artificial hair to natural hair. Using the hair liquid agent applicator of this example, adhesive is applied to the contact point between natural hair 31 and artificial hair 32, and the artificial hair 32 is fixed to the natural hair 31. In this way, there is no need to form a knot in the artificial hair, and a more natural look is achieved.

[0083] (A) is a diagram showing natural hair 31, artificial hair 32, and hair liquid applicator 1. The arrows in the diagram schematically show the application of light pressure by hand. (B) is a diagram showing the adhesive pooling around outlet 26 (the valley of the V-shape). When applying adhesive to hair, it is easier to apply it if the adhesive is allowed to pool around outlet 26 before applying it to the hair.

[0084] The area where the adhesive is applied is not limited to the contact point between the natural hair 31 and the artificial hair 32. The area where the natural hair 31 and the artificial hair 32 contact and the surrounding area are covered with adhesive to bond them together. In this way, the adhesive strength can be improved. The hair liquid applicator of this embodiment has a V-shape formed in the pen tip, which makes it easier to apply the adhesive so as to wrap around the area where the natural hair 31 and the artificial hair 32 contact each other. By bringing the contact point between the natural hair 31 and the artificial hair 32 into contact with or close to the V-shaped groove and rotating the pen body, the adhesive can be applied so as to wrap around the area where the natural hair 31 and the artificial hair 32 contact each other.

[0085] When the liquid agent is an adhesive, as in this embodiment, it is preferable that the liquid agent be a direct liquid agent that is contained in the pen body. For example, the adhesive can be applied from the pen tip by lightly pressing the pen body with a hand. The pen tip is preferably provided with a discharge port, from which the adhesive is discharged. It is preferable that the pen body be configured so that the adhesive is discharged from the discharge port when, for example, light pressure is applied by hand to the grip portion (the part that is held in the hand). This makes it easy to apply the adhesive. When working while holding the pen in the hand, the adhesive can be discharged from the discharge port by pressing the grip portion of the pen with a finger, making work easier. The discharge port may also be called a discharge port, etc.

[0086] In the liquid hair applicator of this embodiment, the grip portion of the pen body is made of a flexible material. For example, a plastic resin is used as the flexible material. The adhesive is viscous and can be retained around the discharge port (for example, in the valley of the V-shaped portion). The adhesive can be retained before application to the hair, or it can be applied directly to the hair without retaining the adhesive.

[0087] When fixing artificial hair to natural hair as in this embodiment, adhesive may be applied to natural hair 31 before contacting artificial hair 32, or adhesive may be applied to artificial hair 32 before contacting natural hair 31, or adhesive may be applied to natural hair 31 before contacting artificial hair 32, or adhesive may be applied after contacting natural hair 31 and artificial hair 32. The hair liquid agent applicator of this embodiment can be held and used with one hand, and since it contains adhesive, there is no need to separately supply adhesive, it can be used continuously, and adhesive can be applied to the desired location well and efficiently.

[0088] <Other Examples> Other embodiments will be described. The hair liquid agent applicator of the present invention may be used to form knots. In hair-augmenting methods, artificial hair is tied to the roots of natural hair. The knot of the artificial hair tied to the roots of natural hair moves upward as the natural hair grows. If the knot moves upward, it may get caught when brushing, causing an uncomfortable feeling. To reduce this discomfort, a forming agent is applied to smooth the knot. When used to form knots, an ultraviolet-curing resin is used as the forming agent, for example. By applying ultraviolet-curing resin and irradiating it with ultraviolet light, the knot can be smoothed.

[0089] The configuration of a hair liquid applicator when applying a molding agent can be, for example, as follows: A direct-injection type in which the molding agent is built into the pen body. An outlet is provided at the tip of the pen, and the molding agent is discharged from the outlet. The molding agent is discharged from the outlet when light pressure is applied to the grip part of the pen body (the part held in the hand). The grip part is made of a flexible material (e.g., plastic resin), and the molding agent is discharged from the outlet when light pressure is applied. In this way, the molding agent can be easily applied.

[0090] The hair liquid agent applicator may also be used for the purpose of removing artificial hair. When artificial hair is tied to natural hair and the natural hair grows, the knot moves upward. As a result, the knot becomes more noticeable, and for example, it looks like split ends rather than hair extensions, which detracts from the natural look. Therefore, by applying an abrasive to the knot and handling it with the tip of the pen, the knot can be scraped off, allowing the artificial hair to be removed without cutting the natural hair, and the added hair can be peeled off.

[0091] When a hair liquid applicator is used for the purpose of removing artificial hair, it may be configured, for example, as follows: A direct liquid type applicator is used, with the abrasive built into the pen body. An outlet is provided at the pen tip, from which the abrasive is discharged. The abrasive is discharged from the outlet when, for example, light pressure is applied to the grip part of the pen body by hand. The grip part is made of a flexible material (e.g., plastic resin), and the molding agent is discharged from the outlet when light pressure is applied. In this way, the abrasive can be easily applied. [Explanation of symbols]
