Description

  The present invention relates to a toothbrush, a hairbrush or a body brush containing germanium in a bristle material.

In recent years, the effect of negative ions emitted by germanium and the like has been in the spotlight as health consciousness has increased.
Germanium is a typical semiconductor, and can be classified into two types of inorganic germanium and organic germanium. One is inorganic germanium as a mineral widely distributed in the earth's crust, and the other one is contained in plants that grow by absorbing ingredients from soil such as ginseng, turf, sarnoshock, and garlic. Organic germanium.
Germanium has unique properties. By applying a small amount of energy, such as heat above 32 ° C, electricity, friction energy, light, etc., the negative electrons in the outermost shell (N shell) become free electrons. It is known that negative ions are emitted and far infrared rays of about 100 microns are generated.
Germanium has various health effects, and typical actions are as follows.
(1) Purify the blood, thereby making the blood weakly alkaline and making the blood so-called smooth.
(2) Due to the semiconductor action of germanium, blood circulation promotion, blood pressure stability, autonomic nerve normalization, and metabolism are enhanced.
(3) Return bioelectrons to normal.
(4) Remove fatigue and pain.
(5) Emits far-infrared rays above 32 degrees Celsius.
(6) Detoxify and excrete pollutants and toxins in the body and excrete waste products.
(7) The water's molecular motion becomes active, expanding blood vessels in the body and improving blood circulation.
(8) The cells are activated by improving the flow of blood and body fluids.
(9) A lot of fresh oxygen is sent to cells in the body, and rejuvenation of cells can be expected.
(10) Since germanium has an excellent wave function, it promotes a micro massage effect.
Focusing on the various health effects of germanium, and with the recent growing interest in health, health devices and health-related products containing various germanium compounds have been developed and marketed. Known health-related products include bath products aimed at the hot spring effect, supporters for improving blood circulation, dentifrices, etc., but many aim to promote blood flow in the body by wearing them like bracelets. It is a product aimed at that.
Of these, the following are known as dentifrices and the like containing germanium.
(A) Japanese Patent Application Laid-Open No. 11-35437 describes a dentifrice composition containing a naturalized synthetic organic germanium-containing honey. (See Patent Document 1)
(B) Japanese Patent Laid-Open No. 2001-131019 discloses that ganoderma composed mainly of calcium and phosphorus and containing germanium, selenium, and silicon is heated to a high temperature for a long time and carbonized in an almost oxygen-free state. There is described a dentifrice characterized by blending the ganoderma carbide obtained in the dentifrice component. (See Patent Document 2)
(C) In addition, in the utility model registration No. 3059451, in the brush portion composed of a plurality of unit hair bundles, the unit hair bundle is composed of a plurality of large diameter hairs and small diameter hairs, and the length of the small diameter hair is A brush base portion that is longer than the thick hair, the thick hair and the small hair are arranged in a substantially checkered pattern, and the tip of the small hair protrudes from the tip of the thick hair and is provided with the brush portion Has proposed a toothbrush characterized by containing an organic germanium compound. (See Patent Document 3)

With regard to dental health, there is a strong interest in so-called prevention before reaching treatment for tooth decay and periodontal disease.
For example, regarding periodontal disease in which blood circulation disorders are a cause of disease progression, it is said that more than 80% of adults in Japan have periodontal disease or its possibility.
However, periodontal disease has few subjective symptoms such as pain, and most of them progress chronically, so detection is likely to be delayed, and it is often a disease that progresses when subjective symptoms occur.
Periodontal disease is an early stage of the onset of gingivitis due to plaque (also called dental plaque, mainly made of bacterial mass) around the teeth and inflammation of the gums.
As gingivitis continues, plaque accumulates in the groove called the gingival crevice at the boundary between teeth and gums, creating calculus, and more likely to accumulate around the calculus, and the plaque matures. Periodontal disease bacteria increase and destroy periodontal tissue. This is called periodontitis, and in the periodontitis state, the depth of the periodontal groove increases to become a periodontal pocket, and in the deep periodontal pocket, an environment suitable for further activity of periodontal disease bacteria is created. Periodontal tissue destruction proceeds.
Periodontal disease is also one of the major causes of bad breath, and toothbrushing has been promoted as a countermeasure. However, the effect was not long-lasting, and it was not a fundamental improvement measure.

As part of these measures against periodontal disease, attempts have been made to improve the structure of toothbrushes. For example, Utility Model Registration No. 3097882 discloses a toothbrush in which the tip of the toothbrush is thinned to remove plaque accumulated in the gingival crevice, and a long brush with a long and short tip and a thick tip. Proposed toothbrush. (See Patent Document 4)
Further, a dentifrice composition containing germanium as described in Patent Documents 1 and 2, or a toothbrush comprising an organic germanium compound in a brush base portion as described in Patent Document 3 is also known. ing.
However, dentifrices containing germanium are in the oral cavity and some of them exhibit their original effects through contact and friction with toothbrushes and gums, but most of them encounter the opportunity for friction. In other words, it had the disadvantage of being wasted from the oral cavity without exhibiting the original effects of germanium. In addition, there has been the inconvenience of having to always use such special dentifrices. In addition, toothbrushes containing organic germanium compounds in the brush base also have a large volume of the brush base. In addition, it has a drawback that it takes too much time to raise the temperature to a temperature at which germanium can sufficiently exert its effect.

As described above, it is said that the germanium compound has a contact surface temperature of 32 ° C. or higher, and when subjected to friction, negative electrons are emitted and ionized negative ions penetrate into skin tissue or the like due to electron osmotic pressure. . Then, the negative ions cause movement of electrons in the blood, thereby producing an effect of promoting blood flow. In this way, germanium is considered to exert its effect when friction occurs or when the temperature is raised sufficiently, so it is not possible to expect the maximum effect simply by wearing it like a bracelet. .
Especially for the head, since the skin is covered with hair and there is no appropriate means for applying such a germanium product to the scalp, negative ions generated from germanium compounds are efficiently applied to the scalp tissue. It was difficult to infiltrate.
In addition, the above-described toothbrush with a narrow bristles is effective in removing plaque accumulated in the gingival sulcus, but the effect of promoting blood flow and tightening the gums is not sufficient.
In addition, a dentifrice compounded with germanium does not always effectively use the germanium in the dentifrice, and is not only inefficient, but in order to expect such an effect, it is always such a special There was also the annoyance of having to use a different dentifrice.
As described above, the toothbrush in which germanium is mixed in the pedestal portion is not capable of sufficiently exhibiting the original effect of germanium because the volume of the brush base portion is large.

The present inventor has conducted earnest research on how to effectively exhibit the original effect of germanium due to friction or the like without waste. As a result, we thought that it should be applied to products with frictional movements with the body in the form of use, not just products worn like bracelets. As a result, toothbrushing and brushing are inevitably accompanied by frictional movement with the body in their usage, and toothbrushes, hairbrushes, and body brushes can effectively demonstrate the original effects of germanium without waste. It concluded that it was a usage form, and completed this invention.
That is, the present invention relates to the following brush.
1. A brush formed by flocking a synthetic resin bristle material for a brush containing germanium on a base.
2. 2. The brush according to 1 above, wherein the bristle material is a core-sheath type composite fiber, and the sheath part contains germanium.
3. 3. The brush according to 1 or 2 above, wherein the brush is a toothbrush, a hair brush or a body brush.
4). 4. The brush according to 3 above, wherein the brush is a toothbrush.

According to the present invention, the effect of germanium is maximized by the frictional action between the toothbrush and the teeth / gingiva, the hairbrush and the hair or scalp, or the body brush and the skin.
Therefore, according to the brush of the present invention, a sufficient negative ion effect can be obtained, and blood circulation can be promoted and metabolism can be promoted, whereby gingiva and skin can be maintained in a healthy state.
In addition, since germanium has an antibacterial action, it is possible to prevent not only oral sterilization but also contamination of used toothbrushes and the like by bacteria. In particular, the toothbrush of the present invention not only effectively removes dirt from the teeth by vigorous movement of water due to the influence of negative ions, or by ionization of a part of the water, but also promotes blood circulation of the gums. Unprecedented effects on alveolar pyorrhea, bad breath, and caries are achieved. These actions are further enhanced by the combined use of tourmaline, and the effect of keeping teeth white by adding apatite can also be expected.
In addition, the hair brush and body brush of the present invention exhibit the original effects of germanium without waste due to the effective frictional action with the scalp or skin, promote blood circulation and promote metabolism, thereby aging and damaging hair and skin. It is possible to prevent hair, and to maintain youthful and shiny hair and skin.
In particular, when a core-sheath type composite fiber is used, and a strong fiber material is adopted for the core part and germanium is contained in the sheath part, not only the effects of these germaniums are sufficiently exhibited, but also in terms of strength. The result is an excellent brush with a strong back.

The synthetic resin hair material containing germanium of the present invention is prepared by mixing germanium and, if necessary, tourmaline or hydroxyapatite in a synthetic resin such as nylon, polyamide, polyester, polypropylene, styrene, acrylic, etc. It is obtained by doing.
The obtained synthetic fiber is implanted in the brush portion as a brush hair material such as a toothbrush, a hair brush, a body brush or the like. The thickness of the fiber can be adjusted arbitrarily, and the diameter may be about 0.05 mm to 1 mm. When applied to a toothbrush, a diameter of 0.1 mm to 0.6 mm is particularly preferable. For a hair brush, a diameter of 0.1 mm to 1 mm is particularly preferable. For a body brush, a diameter of 0.05 mm to 1 mm is particularly preferable. Further, the hair tip may be rounded or sharpened as desired.
The core-sheath-type composite fiber hair material is not particularly limited, but is preferably made of a polyester resin having a strong bristle shape with nylon 6 such as polyamide 6/10 or polyamide 6/12 having excellent hygroscopicity as a sheath part. The core part can be produced by melt compound spinning according to a conventional method.

As germanium to be used, organic germanium (poly-trans- (2-carboxyethyl) germasesquioxane) contained in plants may be used in addition to inorganic germanium derived from minerals. Preferably it is a germanium dioxide fine powder. When tourmaline is used in combination, a natural mineral powder can be used.
The content of germanium in the synthetic resin is not particularly limited, but is preferably about 0.01 to 5% of the resin amount. The particle size is 0.1 μm to 5 μm, preferably 0.2 μm to 1 μm. When the thickness is 0.1 μm or less, the production becomes complicated, and mixing with the resin is difficult. In the case of 5 μm or more, particles exposed on the hair material surface give unpleasant feeling and reduce the strength of the hair material. When blending tourmaline, the content is preferably 0.01 to 2% of the resin amount. These germanium particles and tourmaline particles can be easily obtained from the market.

The germanium compound may be contained in the resin as it is, but may be supported on porous ceramics. Examples of porous ceramics that can be used include zeolite, fluorite group, kalyokite, molecular sieve, palm chit, montmorillonite, acid clay, activated alumina, silica gel, and diatomaceous earth. The supported ceramic should be as fine as possible, preferably around 5 μm. Further, the blending amount is 0.1 wt% to 5 wt%, particularly preferably 0.1 wt% to 0.5 wt% of the total resin amount.
Further, an antibacterial substance such as silver, copper or zinc metal ions may be contained in the synthetic resin or porous ceramic.

In the case of a toothbrush, tourmaline or hydroxyapatite may be used in combination with these germaniums. Hydroquiapatite (Ca10 (PO4) 6 (OH) 2) is an inorganic material that has been attracting particular attention for dentistry. It removes plaque by its cleaning effect, prevents cavities, etc. by its antibacterial action, and repairs tooth enamel. It also has functions. Since the toothbrush containing hydroxyapatite contains hydroxyapatite in addition to the action and effect of germanium, the toothbrush further has cleaning power and antibacterial power. Moreover, the effect of a tooth repair function and the effect of whitening can also be expected. The content of the hydroxyapatite in the resin is not particularly limited, but it is preferably 0.05% to 5% by weight in the resin.

In the case of a toothbrush, a substance used in the oral cavity such as toothpaste and chewing gum, for example, an abrasive, a wetting agent, a binding agent, a cleaning foaming agent, a flavoring agent, a disinfectant, and the like are further contained in the synthetic fiber. Also good. In particular, it is desirable to add the hydroxyapatite, an antibacterial substance, or metal ions of silver, copper, or zinc.
Below, based on an Example, although the toothbrush which concerns on this invention is demonstrated in detail, this invention is not limited to this. Hair brushes and body brushes can be manufactured in the same manner.

In the manufacture of toothbrush bristles were germanium nylon fibers <br/> East Renairon 612 (manufactured by Toray Industries), 1.2 wt% of a commercially available germanium powder (average particle size 0.4 .mu.m), the tourmaline powder of naturally occurring 0 0.2% by weight of Apacider A (manufactured by Sangi Co., Ltd.) as a hydroxyapatite powder is mixed by 0.2% by weight, and is spun by a known spinning machine to obtain nylon fibers having a thickness of about 0.2 mm. Next, a base with a handle pattern for a toothbrush is formed by injection molding with polypropylene resin. The nylon fiber cut to 10 to 12 mm is planted on one surface of one end of the base to obtain a toothbrush.

The toothbrush manufacturing E Renairon 612 having a core-sheath fibers (manufactured by Toray), 0.8 wt% of a commercially available germanium powder (average particle size 0.4 .mu.m), 0.2% by weight of tourmaline powder naturally occurring, As a hydroxyapatite powder, 0.2% by weight of Apacider A (manufactured by Sangi Co., Ltd.) was mixed to form a sheath resin, 75% by weight of polybutylene terephthalate (Toray PBT1200S manufactured by Toray Industries, Inc.) and polyester elastomer (manufactured by Toray DuPont). Hytrel 6347) A core-sheath composite fiber having a diameter of 0.3 mm is formed by a known melt composite spinning method using a blend polymer composed of 25% by weight as a core resin. Next, the core-sheath conjugate fiber cut to 10 to 12 mm is planted on one surface of one end of the base obtained in Example 1 to obtain a toothbrush.

In the toothbrush, hairbrush and body brush of the present invention, germanium contained in the synthetic resin fiber can generate negative ions and the like effectively by frictional action with teeth, gums and skin. This can be done effectively.
Therefore, the use as a new type of brush that is conscious of good health management is greatly expected.
