CAP FOR WARM-BATH AND METHOD OF FABRICATING

THE SAME Technical Field [1] The present invention relates, in general, to a warm-bathing hat for hair loss prevention and scalp care and a method of fabricating the same and, more particularly, to a warm-bathing hat capable of keeping the scalp clean to prevent depilation and raise hair and a method of fabricating the same. [2] Background Art [3] Alopecia is the loss of hair that frequently occurs due to various causes, including poor metabolism in the roots of hair, poor blood circulation, genetic predisposition, constitutional predisposition, stress, etc. Depilation can be found in various corporal loci, including the vertex. [4] For use in the prophylaxis and treatment of alopecia, a variety of hair growth products are commercially available, including hair loss shampoos, hair growth stimulators, hair tonics, etc. In addition, scalp massaging is known to be effective for keeping the hair healthy. Mostly, scalp massaging is conducted by slightly palpating the scalp with hair brushes or the fingertips. However, it takes a long period of time to massage all of the scalp. In addition, it is required that scalp massage be conducted everyday to have a healthy effect on hair. This is too troublesome for some people to conduct. [5] Recently, clinical treatment methods have been suggested in which prenatal and/or postnatal factors and/or syndromes causing alopecia, e.g., poor blood circulation in capillary vessels around hair follicles, scalp itch, etc., are treated to promote hair growth. [6] Divided into scalp clinics and hair clinics, clinics for hair beauty do not belong to the medical field associated with beauty surgery, hair transplantation or hair removal, but to an aesthetic field associated with hair health [7] The scalp clinic functions to remove oily substances produced by sebaceous glands in the scalp, e.g., sebum, and kill hair follicle mites to prevent the loss of hairs, thereby promoting hair growth and removal, while the hair clinic functions to associate hairs with cell membrane complexes, e.g., vegetable proteins, so as to provide elasticity, gloss and waves for a variety of hair qualities. [8] In the scalp clinic, not only are plant extracts used in the form of shampoos, hair tonics or edible rapa?, but also physical and radiological treatments, such as vibration massage, high frequency wavelength radiation, infrared wavelength radiation, etc., are employed on the scalp. [9] Generally, in the hair clinic, treatment is conducted before a hair permanent. In the hair clinic, a permanent agent containing thioglycollic acid and salts thereof, and cysteine and hydrochloride salts thereof, as well as a treatment agent containing cuticle keratin and a cream containing polypeptide, is applied to hairs. [10] However, in addition to taking a long period of time to conduct, these clinical treatments have the problem in that, when a hair permanent or dyeing is repeated on a damaged scalp, without taking appropriate therapy, poisonous matters are not eliminated so as to hinder the blood circulation around hair roots and to break the nutritive layer around hair roots, which causes the scalp to be weakened, leading to depilation. [11] Conventional hair permanents, dyeing, and decolorization cause damage to the scalp (pimples, allergic reaction, bums, skin cancer, depilation) as well as to hairs. When denaturized by UV light or chemicals, keratin loses its resistance to alkalinity. Particularly, cuticle keratin, which is a kind of hair s cell membrane complex, is converted into readily soluble forms when it is denatured by UV light or chemicals. In addition, when shampooed, porous hairs are deprived of lipids and thus become drier [12] Hair, if damaged by UV light, detergents (soaps, shampoos), chemicals (permanent agents, colorants, decolorizing agents), direct heaters, brushes made of 100% pig hair, combs, etc., become hetrogeneous, dull, tangled, thin, inelastic, stiff, split, and cut. [13] Further, hair permanents, dyeing, and/or decolorization cause a numb sense in the head and leave a chemical smell in the hairs. In severe cases, the scalp becomes dandruffy and itchy and many hairs are lost. Recently, it has been reported that alopecia areata increases due to hair permanents, dyeing and decolorization. [14] To solve the problems mentioned above, Korean Utility No. 20-33882 discloses an osteopathic brush for massaging the scalp and Korean Pat. Laid-Open Publication No. 2002-77301 discloses an apparatus for promoting hair growth and blood circulation. [15] However, these conventional technologies cannot solve the fundamental problem of alopecia and have complicated structures such that they may be used only in special clinic centers, but not in home. [16] Korean Pat. Laid-Open Publication No. 2001-110259 discloses a moxibustion apparatus which can be immobilized onto the head even when the head moves. This moxibustion apparatus is described to have the functions of preventing alopecia, promoting hair growth, minimizing the discomfort of washing the hairs due to the in¬ filtration of moxa into the cuticle, continuously irradiating moxa energy, far infrared light and magnetic fields onto the acupunctural spot of the vertex at a distance at a constant temperature to bring about health improvement and disease prevention, and maximizing the time period of moxibustion thanks to the heat storage of ceramics, without causing skin diseases or hair damage. [17] FlG. 8 is an assembled cross sectional view showing a moxibustion apparatus capable of clinging to the head as disclosed in the published patent. [18] As seen in FlG. 8, the moxibustion apparatus comprises a cylindrical ceramic (4) which consists of a wide upper half and a narrow lower half, with a fine wire net (7) supported on a protrusion (6) formed around a lower inner circumferential surface of the lower half. A moxa piece (8) is loaded onto the wire net and fired. A safety cap (10) consisting of a plurality of aprons (12) is internally inserted into the upper portion of the cylindrical ceramic, so that the aprons elastically adhere to the inner cir¬ cumference of the cylindrical ceramic, preventing the moxa piece from being moved therefrom. A magnetic ring (14) and a wire net (13) are installed on a protrusion (15) formed around a lower inner circumferential surface of a seat (1). At a step (9) formed on an outer circumferential surface of the cylindrical ceramic, the lower half is locked into an upper inner wall (2) of the seat (1) such that an outer circumferential surface of the lower half directly contacts the inner circumference of the seat. Thus, the ceramic (4) combined with the safety cap is integrated with the seat (1). [19] An elastic band (20) having a predetermined length is tied via clips (19) at coupling holes (18) formed at edges of opposite external flanges of the seat. When the resulting structure is applied to the face so as for the band to press against the chin, the elasticity of the band allows the seat to strongly press against the top of the face, thereby im¬ mobilizing the ceramic fixed to the seat. [20] In FlG. 8, reference numeral (8) is air inlets and reference numeral (9) is air outlets. [21] Disclosure of Invention Technical Problem [22] However, the moxibustion apparatus shown in FlG. 8 is inconvenient since the user must fire the moxa piece to utilize the heat from the moxa. Additionally, care must be taken not to stain the hair with a moxa solution. [23] When the scalp is smeared with a moxa solution, the hair must be washed many times using a detergent so as to remove the smell from the hair. [24] Technical Solution [25] An object of the present invention is to solve the problems encountered in prior arts and to provide a warm bathing hat for keeping the scalp clean to prevent depilation, and a method of fabricating the same. [26] Another object of the present invention is to provide a warm bathing hat capable of emitting antibacterial anions onto the scalp to keep hair roots healthy, thereby strengthening the hair roots to promote hair growth, and a method of fabricating the same.

[43] In the warm bathing hat in accordance with a second aspect of the present invention, the adaptor is thinner than the housing. [44] In the warm bathing hat in accordance with a third aspect of the present invention, the adaptor has a protrusion ring internally formed around a lower inner circum- ferential surface thereof. [45] In the warm bathing hat in accordance with a fourth aspect of the present invention, the silicon-based resin comprises a tourmaline powder and a non-tourmaline powder having anionic properties. [46] In the warm bathing hat in accordance with a fifth aspect of the present invention, the non-tourmaline powder having anionic properties is ceramic powder. [47] In the warm bathing hat in accordance with a sixth aspect of the present invention, the silicon-based resin further comprises jade powder and/or yellow earth powder. [48] In accordance with a seventh aspect of the present invention, the warm bathing hat further comprises a band, provided at an outside of the adaptor, for pressing the adaptor against the head. [49] In accordance with an eighth aspect of the present invention, provided is a method of fabricating a warm bathing hat for keeping the scalp clean, comprising: mixing a silicon-based resin, tourmaline powder, and a non-tourmaline, anionic powder to produce a mixture; preparing a first and a second mold for molding a warm water- holding housing which is generally cylindrical, and an adaptor for being applied to the head; filling the mixture in a space formed by the assembly of the first mold and the second mold; and inserting a core into the space formed by the assembly of the first and the second mold to make both the warm water-holding housing and the adaptor in a hollow form, wherein the core has one half for the warm water-holding housing and another half for the adaptor, the half for the warm water-holding housing being smaller in diameter than the other half so as to form the warm water-holding housing at a thickness larger than that of the adaptor, and has a groove ring around an outer circum¬ ferential surface thereof so as to form a protrusion ring that internally protrudes from an inner circumferential surface of the adaptor. [50] In the method in accordance with a ninth aspect of the present invention, the silicon-based resin, the tourmaline powder, and the non-tourmaline, anionic powder are used in amounts from 83 to 94.5 wt%, from 5 to 15 wt%, and from 0.5 to 2 wt%, respectively. [51] In the method in accordance with a tenth aspect of the present invention, the anionic powder is ceramic powder. [52] In the method in accordance with an eleventh aspect of the present invention, the silicon-based resin is in a liquid or gel state in the mixing step. [53] In the method in accordance with a twelfth aspect of the present invention, the silicon-based resin is maintained at 100 to 200 °C in the filling step. [54] In accordance with a thirteenth aspect of the present invention, the method further comprises separating the first mold from the second mold, 8 to 10 min after the completion of the insertion step. [55] First, a description is given of a material, used in the present invention, having an¬ tibacterial activity according to the generation of anions. Tourmaline is used in the present invention. [56] Tourmaline is a crystalline mineral that is used as a gemstone. The gemstone is produced mostly in Brazil, the Ural region of Russia, the Yunnan region of China, Sri Lanka, and Africa and is composed of Ca, K, Na, Al, Cr, Fe, Li, Mg, Mn, and Si, having a hardness from 7 to 7.5, a specific gravity of 3.05 and a melting point from 1,050 to l,100°C. Because in the unit lattice of a tourmaline crystal positive charges are greatly misaligned with negative charges, external stress (pressure or temperature change) generates positive and negative poles at opposite ends of the crystal such that tourmaline can realize permanent electrodes. Higher voltages are generated by a stress distortion in the crystal lattice as the particle sizes are smaller. The high piezo¬ electricity generated across electrodes provides a weak current for animal/plant cells which are located within the electric field. The current has a wavelength from 4 to 14 microns, which falls within the wavelength range of far infrared radiation, and radiates energy into living organisms to promote the activation of cells. [57] As reported previously, tourmaline has been proven to have the functions of ® generating electricity permanently, (D causing ions to flow in air, (D breaking water clusters to make water delicious and harmless, ® activating cells to stimulate the growth thereof, (D maintaining matter fresh, and © promoting blood circulation to activate life energy. [58] Ceramic powders, which are also used in the present invention, can generate anions. [59] Below, reference should now be made to the drawings, in which the same reference numerals are used throughout the different drawings to designate the same or similar components. [60] FIG. 1 is an applied schematic view of a warm bathing hat according to the present invention. FIG. 2 is a cross-sectional perspective view of a warm bathing hat according to the present invention. FIG. 3 is a top view of a warm bathing hat according to the present invention. [61] As shown in FIG. 1, a warm bathing hat (100) according to the present invention is applied to the head of the user. [62] Merely by applying the hat to the head, loading 40-42 °C water through an opening (101) and wearing the hat for 3 to 10 min, the user can keep the scalp clean. [63] In the case of tap water, the chlorine contained in tap water is preferably removed because it may cause atopic dermatitis or alopecia. A tea bag containing potassium hyaluronate?, vitamin C, or charcoal may be soaked in tap water to remove chlorine. [64] As shown in FIG. 2, the hat comprises an elastic, cylindrical warm water-holding housing (110) having an opening (101) through which warm water is filled therein, and an adaptor (120), extending downwards from the warm water-holding housing (110), which is directly applied to the head, an a protrusion ring (130) formed around a lower inner circumferential surface of the adaptor 120. [65] As shown in FIGS. 1 and 2, the warm water-holding housing (110), the adaptor (120) and the protrusion ring (130) are integrally formed of a mixture of a silicon resin, tourmaline powder and anion powder. [66] The warm bathing hat (100) according to the present invention may be man¬ ufactured in a variety of sizes suitable for various sizes of user s heads. However, because the silicon resin is flexible, the hat is preferably manufactured in several standard sizes. [67] In addition, as seen in FIGS. 2 and 3, the warm water-holding housing (110) has a thickness tl of about 2 D and the adaptor (120) has a thickness t2 of about 1 D. [68] The reason why the warm water-holding housing (110) is thicker than the adaptor (120) is that the warm water-holding housing (110) becomes resistant to the expansion caused by the warm water filled through the opening (101), so as to prevent the warm water from flowing out of the warm water-holding housing (110). [69] Protruding a distance of about 1 mm, the protrusion ring (130) functions to prevent the warm water in the warm water-holding housing (110) from flowing down onto the face of the user. [70] If necessary, a band may be provided on the protrusion ring (130) so as to allow the protrusion ring (130) to more closely contact the face of the user from the outside of the adaptor (120). [71] In the warm bathing hat (100) according to the present invention, the warm water- holding housing (110) is about 110 mm long and the adaptor (120) is about 50 mm long, with the protrusion ring (130) positioned 10 mm above the bottom of the adaptor (120). [72] The reason why the warm bathing hat (100) according to the present invention is limited in size is as follows. [73] Generally, the loss of hair proceeds from the forehead or occurs at the central portion of the head. Accordingly, in order to improve blood circulation in the depilated portions thereby reinforcing hair roots, the target of the warm bath is restricted to the forehead and the vertex. [74] Thus, the adaptor (120) may cover the portions just before the ears and the eyebrows, so that warm water has influence on the forehead as well as the central portion of the head. [75] [76] [Another Embodiment] [77] In the above-mentioned embodiment, the warm bathing hat (100) has a thick warm water-holding housing (110) so as to prevent the warm water from flowing out of the hat. In this embodiment, another structure is provided to prevent the warm water from flowing out of the hat, as will be described with reference to FlG. 4. [78] A warm bathing hat in accordance with an embodiment of the present invention, as shown in FlG. 4, comprises a warm water-holding housing (111) which has a truncated hemisphere shape, with an opening formed at the top thereof, and an adaptor (121), extending downwards from the warm water-holding housing (111), which is directly applied to the head of the user. [79] A protrusion ring (131) is formed around a lower inner circumferential surface of the adaptor (121). [80] Also in this embodiment, the hat may be formed from an elastic silicon resin alone or in combination with tourmaline powder and ceramic powder so as to emit anions. [81] In this structure, the warm water in the warm water-holding housing (111) can be prevented from flowing out of the hat since the warm water-holding housing (111) maintains its hemispherical shape. [82] Moreover, because the warm water-holding housing (111) is as thick as the adaptor (121), a process for producing the hat according to this embodiment can be further simplified. [83] Preferably, the warm bathing hat (100) according to the present invention is worn on the head when showering or bathing. Made from harmless silicon resin and anion- emitting tourmaline and ceramic, the hat of the present invention, however, can improve the blood circulation in the head even when it is worn at other times. [84] Referring to FIGS. 5 to 7, a method of fabricating the warm bathing hat according to the present invention is explained. [85] FlG. 5 is a flow chart illustrating the stepwise fabrication of the warm bathing hat according to the present invention. FlG. 6 is a schematic view showing a mold for the warm bathing hat according to the present invention. FlG. 7 is a cross sectional view of the mold shown in FlG. 6. [86] First, a harmless, waterproof silicon resin, tourmaline powder, and ceramic powder are prepared. [87] Then, the tourmaline powder and the ceramic powder are mixed with the silicon resin, and melted according to a typical process. [88] Fabricated into the warm bathing hat (100) according to the present invention, a composition comprises a silicon resin in an amount from 83 to 94.5 wt%, tourmaline powder in an amount from 5 to 10 wt%, and ceramic powder from 0.5 to 2 wt%. [89] Most preferably, the warm bathing hat of the present invention is made from a composition comprising 89 wt% silicon resin, 10 wt% tourmaline powder, and 1 wt% ceramic powder. [90] Next, while being maintained in a liquid state or a gel state, the mixture of the silicon resin, the tourmaline powder and the anion-emitting powder is injected into a cylindrical space formed between a first mold (200) and a second mold (210). [91] At this time, the silicon resin is maintained at 100 to 200 °C. Thus, as seen in FlG. 7, the warm water-holding housing (110) is integrally formed with the adaptor (120). [92] Subsequently, a core (220) is inserted into the silicon resin-based mixture filled between the first mold (200) and the second mold (210). [93] The core (220), as seen in FlG. 7, is smaller in diameter for an upper half than for a lower half so that the warm water-holding housing (110) becomes thicker than the adaptor (120). A groove ring (223) is provided around the outer circumference of the core (200) so that the protrusion ring (230) is formed, protruding from the inner cir¬ cumferential surface of the adaptor (120). [94] 8 to 10 min after the insertion of the core, the silicon resin is cured, followed by separating the first mold (200) from the second mold (210). [95] Afterwards, the core (220) is separated from the molded warm bathing hat (100) which is then subjected to surface polishing. [96] Since the silicon resin is elastic, the core (220) can be readily separated in spite of the protrusion ring (130) formed in the warm bathing hat (100). [97] The present invention is described in detail with reference to the drawings through the embodiments which are, however, not to be construed as the limit of the present invention. [98] For example, although only one protrusion ring (130) is provided on the inner cir¬ cumferential surface of the adaptor (120) in the embodiments suggested above, two or more protrusion rings may be provided to obtain a better waterproof effect. [99] Jade powder and/or yellow earth powder may be combined with the silicon resin mixture so as to obtain more intensive emission of far infrared radiation. [100] Industrial Applicability [101] As described hereinbefore, the warm bathing hat according to the present invention is structured to hold warm water on the head for a predetermined time period sufficient to open skin pores so as to remove sebum, whereby the scalp can be maintained clean, with the concomitant prevention of depilation. [102] In addition, the warm bathing hat according to the present invention emits anions to improve the blood circulation in the head, thereby strengthening hair roots and promoting hair growth. [103] Further, the warm bathing hat can be readily fabricated by the method in accordance with the present invention, and thus can be mass produced at low cost. [104]
