Hereinafter, the present invention will be described in detail with reference to the drawings. The terms and words used in the present specification and claims should not be construed as limited to ordinary or dictionary terms and the inventor may appropriately define the concept of the term in order to best describe its invention It should be construed as meaning and concept consistent with the technical idea of the present invention.

1 is a plan view of the bristle according to the invention, Figure 2 is a perspective view of the bristle according to the invention. 3 and 4 are longitudinal and cross-sectional views of the bristles according to a preferred embodiment of the present invention.

Referring to the drawings, the toothbrush 100 has a handle portion of a predetermined length, a toothbrush head portion 20 having a predetermined thickness and width and connected to the handle portion, and a plurality of bristles 10 formed on an upper surface of the toothbrush head portion 20. ).

The bristle 10 is a cylindrical model and the inside of the bristle 10 is composed of an inner core layer 1 and an outer shell layer 2 surrounding the inner core layer. The inner core layer 1 has a cylindrical shape having a predetermined thickness in the longitudinal direction of the bristles in the center of the bristles 10, and the opposite end of the toothbrush head 20 is open. The outer shell layer 2 surrounds the inner core layer 1 to a predetermined thickness on the outer surface of the inner core layer 1.

The present invention as an embodiment at least one salt component surrounding the inner core layer and the inner core layer of the general brush head material selected from the group consisting of sun salt, formula salt, refined salt, pine salt, suicide, molten salt, processed salt and phosphate It is a bristle of a multilayer structure including an outer shell layer containing. In another embodiment, a general bristle material surrounding the inner core layer and the inner core layer containing at least one salt component selected from the group consisting of sun salt, formula salt, refined salt, pine salt, suicide, molten salt, processed salt and phosphate It is a bristles of a multi-layer structure consisting of.

Preferably, the bristles of the multi-layered structure surround the inner core layer of the general bristle material and the inner core layer, and at least one salt selected from the group consisting of sun salt, salt salt, refined salt, pine salt, magnetic salt, molten salt, processed salt and phosphate salt. An outer shell layer containing the component. When the layer containing the salt component is an outer shell layer, the salt component is more easily eluted, and the inner core layer is composed of ordinary bristles, so that the elasticity and physical properties of the bristles may be less affected.

The bristle of the multi-layered structure has a surprising effect of increasing the content of the functional ingredient and effective release as compared to the single-core bristle without the multi-layered structure. The simple incorporation of functional ingredients into single-core bristles is extremely limited due to basic qualities such as breaking strength, tensile strength and elasticity of the bristles. However, the bristle of the multilayer structure according to the present invention contains a functional component, ie, a salt according to the present invention, in the outer shell layer or the inner core layer, while maintaining the basic quality such as breaking strength or tensile strength of the bristles and elasticity of the bristles to the maximum. It may contain these. In addition, when the functional ingredients, which are salts according to the present invention, are contained in the outer shell layer, which is the bristle surface, and at the same time, the water-soluble polymer is contained in the outer shell layer, more effective release of the functional components by water absorption upon brushing can be expected.

Hereinafter, the components of the bristles of the present invention will be described in detail.

The layer containing the salt component according to the present invention is used to prepare at least one salt component, a polymeric material and conventional bristles selected from the group consisting of sun salt, preparation salt, refined salt, pine salt, suicide, molten salt, processed salt and phosphate salts. And water-insoluble high molecular materials.

One of the components of the layer containing the salt component according to the invention is a polymeric material. More preferably the polymer is a water soluble polymer material. When brushing with bristles including a water-soluble polymer in a layer containing the salt component, the release of the salt component may be maximized due to the water absorption of the water-soluble polymer other than the tooth pressure.

Preferably, the polymer material according to the present invention includes polyacrylic polymers such as polyacrylic acid, poly (meth) acrylate, and polyvinylacetate; Cellulosic polymers such as cellulose, hydroxypropylmethylcellulose, hydroxymethylcellulose, methylcellulose, ethylcellulose, hydroxymethylcellulose, hydroxyethylcellulose, hydroxyethylmethylcellulose and carboxymethylcellulose; Polyalcohol-based polymers such as polyvinyl alcohol, polyethylene glycol, polypropylene glycol, and polypropylene glycol copolymer; Polyvinylacetate phthalate; Polyethylene oxide; Latex; Shellac; Rosin waxes; Polyamide; polyester; Polyolefin; silicon; And at least one polymer material selected from the group consisting of synthetic rubbers.

More preferably, as the water-soluble polymer material according to the present invention, a polyacrylic polymer, a cellulose polymer, a polyalcohol polymer, polyethylene oxide, or the like is used alone or in combination.

One of the components of the layer containing the salt component according to the present invention is a water insoluble polymer material which is used to prepare conventional bristles. For example, it means a water-insoluble high molecular material such as polypropylene, polyethylene, polyethylene terephthalate, polybutylene terephthalate, polytrimethylene terephthalate, polyurethane, nylon component and the like, but is not limited to the above examples.

One of the components of the layer containing the salt component according to the invention is at least one salt component selected from the group consisting of sun salt, salt salt, refined salt, pine salt, suicide, molten salt, processed salt and phosphate salts.

At least one salt component selected from the group consisting of sun salt, salt salt, refined salt, pine salt, suicide, molten salt, processed salt, and phosphate enhances flavor when brushing teeth, and prevents antibacterial, anti-inflammatory, anti-inflammatory, tartar prevention, and syring prevention. It can help with oral health. In particular, the phosphate salt in the salt can be effective for oral health by showing the efficacy of prevention of tartar, preventing the infection.

The content of the salt component is characterized in that it contains 0.1 to 10% by weight, more preferably 0.5 to 5% by weight relative to the total bristle weight. When the content of the salt component is less than 0.1% by weight, preferably less than 0.5% by weight of the final bristles, the release of the salt component when the brushing is insignificant, which is difficult to have an effect, and exceeds 10% by weight, preferably more than 5% by weight. There is a problem in that it is not easy to manufacture the bristles by spinning to maintain the inherent physical properties of the bristle itself.

The layer that does not contain the salt component (an inner core layer when the salt component is contained in the outer shell layer, and an outer shell layer when the salt component is contained in the inner core layer) includes a material used to prepare conventional bristles. For example, it means a water-insoluble high molecular material such as polypropylene, polyethylene, polyethylene terephthalate, polybutylene terephthalate, polytrimethylene terephthalate, polyurethane, nylon component and the like, but is not limited to the above examples.

The thickness of the inner core layer and the thickness of the outer shell layer of the bristles of the multi-layered bristle according to the present invention may be used to be adjusted depending on the purpose of use in a ratio of 1: 1 to 1:10.

Hereinafter, a process using the dual core extrusion spinning method of the bristles manufacturing method will be described.

A common bristle component to be used for the outer shell layer and a mixed component including a salt component and a polymer material to be used for the inner core layer are introduced into different raw material inlets. After applying heat, the yarn is spun under conventional extrusion spinning conditions and passed through an extrusion spinning molding machine in which the layers are separated. The bristles are manufactured by having a double layer structure passed through the molding machine to have an appropriate strength and tensile force through a stretching process and a cooling process. At this time, the thickness of the outer shell layer and the inner core (core) layer can be used to adjust according to the intended use.

When using the toothbrush having a multi-layered bristles according to the present invention, the salt component according to the present invention is released by brushing pressure and moisture when brushing the tooth, and the salt component according to the present invention acts on the teeth or gums to prevent antibacterial, anti-inflammatory and anti-inflammatory It will help prevent various oral diseases such as prevention of tartar, and prevention of infection.

Hereinafter, embodiments of the present invention will be described in detail to facilitate understanding of the present invention. However, the embodiments according to the present invention can be modified into various other forms, and the scope of the present invention should not be construed as being limited to the following embodiments. Embodiments of the invention are provided to more fully describe the present invention to those skilled in the art.
