Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a bristles containing baking soda and a bristle including the bristles,

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an oral toothbrush, and more particularly, to a brush bristle and a toothbrush capable of suppressing bacteria that may occur, infect or propagate even when a toothbrush is stored, .

Conventional bristles are formed by extruding polypropylene, polyethylene propalate, polyurethane, nylon, and the like and stretching them. The bristles thus formed have different strengths and characteristics according to their components, and using these characteristics, various bristles are provided.

Since a general toothbrush is used for food waste or plaque removal, contaminated materials may remain in the bristles after using the toothbrush. In fact, no matter how well it is cleaned, it is not possible to completely remove contaminants from the toothbrush after use, which can lead to bacterial growth and can seriously affect the oral hygiene of the user while continuing to be used in the future.

A toothbrush that makes direct contact with the user's body must be hygienic at all times. After storing the toothbrush, various bacteria may breed due to moisture remaining in the bristles during storage, which may cause disease.

In order to solve the problem of such a toothbrush, a composition for sterilizing a toothbrush such as disclosed in Japanese Patent Application Laid-Open No. 10-2002-0066060 is disclosed, and a toothbrush sterilizing apparatus and the like are disclosed as in Patent Document 10-2002-0067068, It is ineffective in that its use is complicated. In addition, although a toothbrush incorporating an ultraviolet lamp is disclosed in Japanese Patent Application No. 10-0737691, it is disadvantageous in that it is difficult to use and maintain since a separate power source is used.

The present invention provides a brush bristle including a bristle-inhibiting or sterilizing function without using an ultraviolet lamp or a separate power source, and which can be used harmlessly to a human body at an additional cost even for a long period of use, and a toothbrush including the brush bristle.

More specifically, the present invention provides antibacterial and deodorizing purifying effects in oral cavity as well as hygienic storage by using baking soda, and it is possible to improve the health of users by strengthening teeth and various kinds of gum disease The present invention provides a toothbrush comprising a toothbrush and a toothbrush.

The present invention provides a brush bristle including bristles in an extremely triangular shape to increase cleaning power and to secure strength to facilitate removal of garbage and plaque, and a toothbrush including the bristles.

According to one exemplary embodiment of the present invention, a toothbrush comprising a head portion and a handle is characterized in that the bristles implanted in the head portion contain baking soda in the form of particles.

The bristles according to the present invention are characterized in that the baking soda is contained in the bristles and the baking soda particles contained therein can be continuously eluted through repeated use. The eluted baking soda can also serve to clean the oral cavity during tooth brushing, but it is also possible to suppress the propagation of bacteria on the surface of the bristles during storage after use.

For reference, baking soda is a compound called sodium bicarbonate (NaHCO ₃ ), sodium bicarbonate, sodium bicarbonate, etc., and is a white crystal mass or a crystal component. Baking soda is readily hydrolyzed by dissolving in water and used mainly as a swelling agent in the manufacture of bread or biscuits. In particular, baking soda may be used to soften tissue cells of food by improving protein retention. In addition, baking soda is widely used as an alkaline agent and a buffering agent, and because it has a property of adsorbing contaminants, it is also used as a substitute for a detergent, but it is harmless to the human body in that it can be used for edible purposes.

Preferably, the baking soda has an average particle size of about 0.1 to 100 micrometers (mu m), and preferably about 0.1 to 10 micrometers (mu m).

In order to produce the baking soda having an average particle size of 0.1 to 100 micrometers (탆), a conventional particle forming or crushing method may be used. In the crushing, milling, grinding, crushing, Method. ≪ / RTI >

In the extrusion molding of the bristles according to the present invention, the raw material, that is, the synthetic resin mixture may be a polypropylene, a polyester, a polyethylene, a polystyrene, a polyamide, a polyethylene terephthalate, a polytrimethylene terephthalate, a polybutylene terephthalate, , Synthetic resin composed of at least one of polycarbonate, polyphenylene oxide, polyoxymethylene, elastomer, polyurethane, acrylonitrile, silicone and nylon, and baking soda. At this time, when the synthetic resin mixture is 100% by weight, the synthetic resin may be mixed at 99% by weight or more, baking soda may be mixed at 0.01 to 1.00% by weight, preferably 0.01 to 0.50% by weight And most preferably 0.05 to 0.50% by weight, based on the total weight of the composition.

Further, the bristles according to the present invention may be provided in the form of a needle-like hair. It can be helpful for people with gum disease or periodontal disease by making the ends of the simulations thin and smooth. However, the bristles of the needle-shaped bristles are basically thin and soft, so that the cleaning ability may be lowered.

In order to solve this problem, it is also possible to form the bristles according to the present invention in a double structure. That is, the bristles may be formed by extrusion molding, but an outer shell layer formed around the inner core and the inner core may be formed. The inner core and the outer shell layer may be formed at the same time, or the outer core layer may be formed after the inner core is formed. When the bristles according to the present invention are provided in acicular form, the free end of the inner core may be exposed from the free end of the outer shell layer, and the extent and size of the exposed area of the inner core may vary .

In the present invention, baking soda may be contained in either the inner core or the outer shell layer, or both the inner core and the outer shell layer, even if the bristles are double molded.

According to the present invention, further external bristles having different physical properties along the periphery of the bristles can be provided. The outer bristles can be formed along the periphery of the inner bristles, and the outer softness of the bristles can be adjusted since the outer bristles form the outer walls with relatively strong external strength.

In particular, in forming the external bristles, the bending strength of the bristles may be improved by extruding two or more different synthetic resin materials into a spiral shape. Of course, the spiral external bristles may also include a baking soda component.

A method of manufacturing a bristle according to the present invention comprises:

a) preparing a filament from a synthetic resin mixture comprising a synthetic resin and baking soda;

b) cutting the filament;

c) dipping one end of the filament of step b) in a processing bath containing an acidic or alkaline solution; And

d) dipping the other end of the filament of step c) in a processing bath containing an acidic or alkaline solution.

The filaments can be produced by melting and extruding by using a general spinning method such as melt spinning, dry spinning, wet spinning or wet spinning.

The process of melting and extruding the filament is carried out through a nozzle having 32 to 120 spinnerets (0.5 to 2 mm in diameter) formed in a radiator heated to 220 to 280 ° C. The extruded water may include a stretching process to increase the flexibility and strength of the filament. The stretching process is determined by the winding speed and is preferably 3 to 6 times at a temperature of 150 to 220 ° C. The stretching process is preferably performed once to four times.

The diameter of the filament produced in the step a) is preferably 0.05 to 1 mm.

The step b) may include a step of bundling the filaments prepared in the step a), and the bundle may have a thickness of 40 to 60 mm.

It is preferable to use a different type of dipping solution depending on the kind of the resin constituting the bristles. Preferably, when the synthetic resin is a polyamide such as nylon, an acidic solution such as hydrochloric acid, nitric acid or sulfuric acid is used When the synthetic resin is polyester, an alkaline solution such as sodium hydroxide, ammonium hydroxide, calcium hydroxide or the like is preferably used. The taper solution may use one or more solutions, and one or more taper processes may be performed depending on the type of the synthetic resin.

Upon completion of the tapering process, it may include a washing process two to three times in water containing water or an acid or an alkali neutralizing agent.

The step of manufacturing the toothbrush 10 may further include the step of removing the filament produced through the above step. The toothbrush may be manufactured from one or more materials selected from synthetic resin materials, metal materials, ceramic materials, plastic materials, wood, and the like within the scope of the object of the present invention.

INDUSTRIAL APPLICABILITY The toothbrush of the present invention uses bristles containing a baking soda component to improve antimicrobial properties by suppressing the propagation of various bacteria caused when the toothbrush is stored and to clean the teeth through the polishing action of the baking soda and the odor removing effect It is also possible to obtain a tooth whitening effect.

Through the baking soda which is continuously eluted with minute amount, it is possible to decompose bacteria and foreign substances in the oral cavity and the toothbrush, and it is possible to prevent and treat various gum diseases and periodontal diseases by cleaning the toothbrush and cleaning the mouth.

The amount of baking soda can be determined while controlling the content of the baking soda. Since the ultraviolet lamp or the disinfecting device is not used, the baking soda can be expected to be effective not only at low maintenance cost but also during traveling.

In addition, the bristles can be provided in the form of an acicular hair or an extreme triangular shape to extend the cleaning range to every corner, and the cleaning force of a desired strength can be increased by using the double structure or the spiral bristles.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. However, the present invention is not limited to the embodiments. For reference, the same numbers in this description refer to substantially the same elements and can be described with reference to the contents described in the other drawings under these rules, and the contents which are judged to be obvious to the person skilled in the art or repeated can be omitted.

1 is a perspective view of a toothbrush according to an embodiment of the present invention.

Referring to FIG. 1, a toothbrush 10 includes a head 20 and a handle 30, and a bristle 100 is implanted into the head 20. The shapes and materials of the head 20 and the handle 30 can be variously selected and changed and the process of implanting the bristles 100 into the head 20 is also obvious to those skilled in the art, It is omitted.

However, the bristles 100 according to the present embodiment may include the baking soda 150. [ The baking soda 150 finely divided into a predetermined size is contained in the inside or the surface of the bristles, and can be exposed to the outside or can be separated and eluted according to the use of the toothbrush.

The baking soda 150 eluted to the outside may serve to clean the oral cavity at the time of brushing. However, the baking soda 150 remaining on the surface of the bristles 100 or the head portion 20 prevents the bacteria from propagating in the toothbrush 10 . The effect of baking soda on the toothbrush can be achieved by the antibacterial and deodorizing effects in the oral cavity when brushing teeth, strengthening the teeth, improving various gum diseases and improving the health of the user, and also obtaining a tooth whitening effect .

Preferably, the baking soda 150 has an average particle size of about 0.1 to 100 micrometers (mu m), preferably about 0.1 to 10 micrometers (mu m), in the process of forming the bristles It can be mixed with the synthetic resin and contained in the bristles through extrusion molding.

When brushing according to the present invention, baking soda is continuously sprayed in the course of worn brush head 100. If baking soda powder of less than 0.1 micrometer is added, it is too small to achieve a proper antimicrobial effect, When baking soda powder having a particle size exceeding 100 micrometers is added, carbon dioxide gas escapes itself and causes extrusion molding defects. Therefore, it is preferable to use a size within about 0.1 to 100 micrometers.

Further, in order to mold the bristles 100 according to the present invention, a synthetic resin mixture basically containing a synthetic resin and baking soda may be used. The synthetic resin mixture can contain various additives besides synthetic resin and baking soda. However, the synthetic resin to be used in the basic compounding of the synthetic resin mixture may be polypropylene, polyester, polyethylene, polystyrene, polyamide, polyethylene terephthalate, polytrimethylene terephthalate, polybutylene terephthalate, polyvinyl chloride, polycarbonate, poly For example, at least one of phenylene oxide, polyoxymethylene, elastomer, polyurethane, acrylonitrile, silicon and nylon. The composition ratio of the synthetic resin may be more than 99% by weight and the baking soda may be mixed in a proportion of 0.01 to 1.00% by weight based on 100% by weight of the synthetic resin mixture.

If the baking soda is added in an amount exceeding 1.00 wt% based on 100 wt% of the synthetic resin mixture, the viscosity of the synthetic resin may be decreased to make the production difficult. If the baking soda is added in an amount less than 0.01 wt%, the strength of the bristles may increase, May be reduced to make it incompatible with tooth brushing.

The bristles according to the present invention may be provided in the form of a needle-like hair or an extreme triangular shape as in the present embodiment, but may be provided in various shapes and configurations such as a general hair, a two-step fine hair, and a three-dimensional hair arrangement.
