[0015] Hereinafter, the hair stick according to the present disclosure will be described based on the embodiments with reference to the drawings. In this specification and claims, the term "hair dye" is used as a general term for hair cosmetic agents that contain a bleaching agent without a dye.
[0016] First embodiment: The hair stick 10 according to the first embodiment can be used together with a hair cap worn by a user on the head. More specifically, the hair stick 10 is used to pierce the hair cap and pull out a desired amount of hair. As shown in FIG. 1 and FIG. 2, the hair stick 10 according to the first embodiment includes a main body 11, a hair pull-out part 12, and a disk-shaped part 13. The hair stick 10 is integrally molded, for example, by injection molding using a synthetic resin such as polypropylene or polyethylene. The hair stick 10 may be formed from a metal material such as stainless steel, or wood. The main body 11 is a rod-shaped body having one end 11a and the other end 11b. The main body 11 has a cross-sectional shape in which one side is longer than the other side perpendicular to the first side, and in this embodiment, the main body 11 has a substantially elliptical cross-sectional shape having an upper surface 11t and a lower surface 11u, and a left side surface 11l and a right side surface 11r connecting the upper surface 11t and the lower surface 11u, as shown in FIG. 3. In an appropriate use mode of the hair stick 10, the main body 11 has a major axis direction (one direction) that coincides with the vertical direction, i.e., the up-down direction, and a minor axis direction (the other direction) that coincides with the horizontal direction, i.e., the left-right direction. Hereinafter, the major axis direction of the main body 11 is also called the height direction, and the minor axis direction is also called the width direction. The main body 11 has a side shape in which the height is highest at the center and the height decreases in an arc toward the one end 11a and the other end 11b. In this embodiment, the one end 11a has the smallest height in the main body 11. The main body 11 has a planar shape in which the width is widest between the center and the other end 11b. This wide shape improves the grip of the fingertips during use, stabilizing the operation of the hair stick 10. In any place, the width of the main body 11 is smaller than the height of the main body 11. A plurality of protrusions 110 are formed on one edge of the main body 11, specifically, on the top surface 11t. The plurality of protrusions 110 allow the user to recognize the appropriate manner of use of the hair stick 10, that is, the position. More specifically, the user's index finger and middle finger come into contact with the plurality of protrusions 110, allowing the user to recognize the correct position of the hair stick 10. The plurality of protrusions 110 also function as a slip prevention.In this embodiment, a protrusion 110 having a substantially rectangular shape extending in the width direction is illustrated, but the shape of the protrusion 110 may be a circle, a square, a polygon, or any combination of these.
[0017] The hair pull-out part 12 is a part of the hair stick 10 for hooking hair, and is formed by extending from one end 11a of the main body 11. The hair pull-out part 12 has a tip 121, an expansion part 122, and a hook-shaped part 123. The hair pull-out part 12 has a height equal to or less than the minimum height in the major axis direction of the main body 11 throughout. The cross-sectional area of the hair pull-out part 12 is set to a size for drilling a hole in the hair cap corresponding to an appropriate amount of hair. The tip 121 has a shape that does not hurt the user's head when it hits it, and that allows the hair cap to be easily drilled. The hair cap is a bag-like cap that covers the user's hair and is made of, for example, polyethylene or polyvinyl chloride. The tip 121 has a substantially semicircular shape that is symmetrical with respect to the central axis of the main body 11, that is, an R shape. The radius of curvature of the tip 121 depends on the material of the hair cap, but is preferably 0.25 mm or more and 1.5 mm or less, and more preferably 0.75 mm, so that it does not hurt the user's head when it hits the hair cap and the hair cap can be easily perforated. The expansion part 122 has a shape that expands in the major axis direction from the tip 121 toward the main body 11. The hole perforated by the tip 121 is enlarged by the expansion part 122. The height of the hair pull-out part 12 is determined by the height of the expansion part 122, and the height of the expansion part 122 is equal to or less than the minimum height of the main body 11 in the major axis direction. The expansion angle α of the expansion part 122 is preferably 45 degrees or more and 90 degrees or less. The hook-shaped part 123 is formed toward the main body 11 between the expansion part 122 and the main body 11. The lower end of the hook portion 123 extends from the extension portion 122 toward one end 11a of the main body 11 in parallel with the central axis of the main body 11. The upper end of the hook portion 123 has a protrusion 123a for hooking hair. The protrusion 123a protrudes toward the main body 11 and has a hook angle β of 30 degrees or more and 90 degrees or less in order to pull out a desired amount of hair. In this embodiment, the protrusion 123a is preferably formed to a height equal to or less than the minimum height of the main body 11 and parallel to the axis of the hair stick 10, as shown in FIG. 4. In other words, the protrusion 123a can also be said to be a cutout portion formed in the hook portion 123.According to the shape and dimensions of the protrusion 123a, when the hair stick 10 is pulled out from the hair cap, interference with the hair cap can be reduced or prevented, and the hair stick 10 can be easily pulled out. Also, damage to the hole formed in the hair cap can be reduced or prevented. The protrusion 123a may be formed by cutting out the hook portion 123 that is integrally molded.
[0018] The disk-shaped portion 13 is a circular plate-shaped portion extending from the other end 11b of the main body 11 in the long diameter direction of the main body 11. The disk-shaped portion 13 functions as a spatula for stirring the hair dye. The disk-shaped portion 13 also functions as a counterweight for the main body 11 and the hair pull-out portion 12. The radius of the disk-shaped portion 13 is the same as the maximum height of the main body 11, and it is desirable that the diameter of the disk-shaped portion 13, i.e., the length in the vertical direction and the height, are about twice the maximum height of the main body 11. The other end 11b of the main body 11 and the disk-shaped portion 13 are continuously connected by a curved line through the curved portion 14. The curved portion 14 abuts between the thumb and index finger of the user when using the hair stick 10, and has the function of preventing the hair stick 10 from slipping off.
[0019] According to the hair stick 10 of the first embodiment described above, the usability of the hair stick 10 can be improved. Specifically, since the hair stick 10 of the first embodiment has the hair pull-out part 12 having a height equal to or less than the minimum height of the main body 11, it is possible to reduce or prevent interference with the hair cap when hooking the hair and pulling it out of the hair cap. In addition, it is possible to reduce or prevent damage to the hole of an appropriate size corresponding to the appropriate amount of hair perforated in the hair cap. As a result, it is possible to smoothly or easily pull out the appropriate amount of hair. Since the hair stick 10 of the first embodiment has a plurality of protrusions 110 on the upper surface 11t of the main body 11, it is possible to suppress or prevent slippage during use, and it is also possible to easily allow the user to recognize the correct position of the hair stick 10 for using the hair pull-out part 12 in the correct direction through the tactile sensation of the fingertips, and it is possible to smoothly or easily pull out the appropriate amount of hair. The hair stick 10 according to the first embodiment has a generally semicircular tip, which makes it easy to drill holes in the hair cap and reduces or eliminates the uncomfortable feeling when it comes into contact with the head.
[0020] As shown in Figures 5 and 6, the user uses the hair stick 10 to make a hole in the hair cap 60 at a location corresponding to the location of the hair desired to be dyed, forming an opening. The hole in the hair cap 60 is made by the pointed end 121 of the hair puller 12, and an opening of the desired diameter is made by the extension 122. The user can pull out the desired amount of hair by hooking the hooked portion 123, more specifically the protruding portion 123a, onto the desired hair and pulling out the hair stick 10. The user can recognize the correct position of the hair stick 10, where the hooked portion 123 is facing upwards, by feeling the protruding portion 110 of the hair stick 10 with his fingertips, and can easily pull out the desired amount of hair. Since the height of the hook-shaped part 123 is equal to or less than the minimum height of the main body 11, when the hair stick 10 is pulled out, the hair pull-out part 12 is pulled out without interfering with the hair cap 60, and damage to the opening is also prevented or suppressed. The user can dye the desired hair by applying the hair dye obtained by mixing the multiple agents using the disk-shaped part 13 to the pulled-out hair, either beforehand or after pulling out all the hair.
[0021] As the hair dye composition, for example, the composition of the following formulation example is used. <Oxy Cream> Component Content (mass%) Hydrogen peroxide 5.810 Cetanol 11.100 Stearyl alcohol 3.600 Polyoxyethylene cetyl ether (10E.O.) 3,000 Polyoxyethylene cetyl ether (20E.O.) 4.800 Liquid Paraffin 6.000 Polyethylene glycol 400 1.500 Camellia oil 0.001 Jojoba oil 0.001 Squalane 0.001 Shea butter 0.001 Hydroxyethanediphosphonic acid 0.082 Phenoxyethanol 0.037 Diethylene glycol monoethyl ether 0.022 Phosphoric acid 0.020 Disodium hydrogen phosphate 0.100 Purified water 63.925 Total 100.000 <Bleach Powder> Component Content (mass%) Ammonium persulfate 11.309 Silica 2.917 Potassium persulfate 60.214 Sodium persulfate 6.250 Disodium edetate 0.800 Sodium metasilicate anhydrous 13.000 Magnesium sulfate 4.000 Zinc stearate 0.500 Gunjo 0.010 Light Liquid Isoparaffin 1.000 Total 100.000 The above-mentioned "Oxy Cream" and "Bleach Powder" can be mixed in a ratio of Oxy Cream:Bleach Powder = 5:1 to obtain a bleaching agent, which can be used to bleach hair.
[0022] Second to sixth embodiments: In the first embodiment, the disk-shaped portion 13 extends from the other end 11b of the main body 11. In contrast, in the hair stick 10a according to the second embodiment, as shown in Fig. 7, the hair brush portion 13a extends. The hair brush portion 13a is used to arrange the pulled-out hair in a loop shape. It can also be used to apply a hair dye evenly to the pulled-out hair.
[0023] In the hair stick 10b according to the third embodiment, as shown in FIG. 8, in addition to the hair pull-out portion 12 formed at one end 11a, a horsetail-shaped hair pull-out portion 13b is formed at the other end 11b. The horsetail-shaped hair pull-out portion 13b allows more hair to be pulled out. In the hair stick 10c according to the fourth embodiment, as shown in FIG. 9, in addition to the hair pull-out portion 12 formed at one end 11a, an earpick-shaped hair pull-out portion 13c is formed at the other end 11b. The earpick-shaped hair pull-out portion 13c has a stopper portion higher than the minimum height of the main body 11, so that the depth of penetration of the earpick-shaped hair pull-out portion 13c into the hair cap can be made constant, and the area of hair to be pulled out can be limited. In the hair stick 10d according to the fifth embodiment, as shown in FIG. 10, in addition to the hair pull-out portion 12 formed at one end 11a, an earpick-shaped hair pull-out portion 13d is formed at the other end 11b. The earpick-shaped hair pull-out portion 13d has a curved shape, so that it is possible to easily pull out hair from the hair area inside the hair cap, which is difficult to pull out with the straight-lined hair pull-out portion 12. In the hair stick 10e according to the sixth embodiment, as shown in FIG. 11, in addition to the hair pull-out portion 12 formed at one end 11a, a tweezers-shaped hair pull-out portion 13e is formed at the other end 11b. The tweezers-shaped hair pull-out portion 13e makes it easier to pull out hair.
[0024] In other embodiments: (1) In the above embodiments, the case where the plurality of protrusions 110, the disk-shaped portion 13 and its modifications 13a to 13e, and the curved portion 14 are all provided has been described, but all of these elements and configurations do not have to be provided, or any combination of these elements and configurations may be provided. These may be changed as appropriate to suit the manner in which the hair stick 10 is used.
[0025] (2) In each of the above embodiments, the multiple protrusions 110 are provided only on the upper surface 11t, but they may be provided only on the lower surface 11u, or protrusions 110 of different patterns may be provided on the upper surface 11t and the lower surface 11u. Any aspect is possible as long as the user can recognize the correct position of the hair stick 10 through the sense of touch. In either case, the user can recognize the correct position of the hair stick 10, and the user can easily pull out an appropriate amount of hair.
[0026] (3) In the above embodiments, the main body 11 has been described as having a substantially elliptical cross-sectional shape with one side longer than the other side, but the main body 11 may have a rectangular cross-sectional shape, or may have a cross-sectional shape with an upper edge and a lower edge instead of the upper surface 11t and the lower surface 11u. Furthermore, in the above embodiments, the major axis direction is vertical, but the major axis direction may be horizontal. In either case, the user can recognize the correct position of the hair stick 10, and the user can easily pull out an appropriate amount of hair.
[0027] Although the present disclosure has been described above based on the embodiments, the above-described embodiments are intended to facilitate understanding of the present disclosure and are not intended to limit the present disclosure. The present disclosure may be modified or improved without departing from the spirit and scope of the claims, and the present disclosure includes equivalents thereof. [Explanation of symbols]
