DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

[0023] In order to fully understand the present invention, operational advantages of the present invention and objects to be achieved by implementing the present invention, the present invention will be described with reference to the accompanying drawings which illustrate preferred embodiments of the present invention and the contents illustrated in the accompanying drawings.

[0024] Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. Like reference numerals illustrated in the respective drawings designate like members.

[0025] FIG. 1 is a flowchart of a manufacturing method of a no-glue cosmetic brush according to an embodiment of the present invention, FIG. 2 is a diagram illustrating a brush hair provided with a fusion portion by applying heat to a lower end thereof after forming a brush hair shape according to an embodiment of the present invention, FIG. 3 is a diagram schematically illustrating that a first pressing portion is provided in an upper region of a hair fixing tube to which the brush hair is coupled according to an embodiment of the present invention, FIG. 4 is a diagram schematically illustrating the inside of the hair fixing tube to which the brush hair is coupled according to an embodiment of the present invention, and FIG. 5 is a diagram schematically illustrating that a side portion of the hair fixing tube is cut after the coupling is completed by providing a second pressing portion in the hair fixing tube according to an embodiment of the present invention.

[0026] As illustrated in these drawings, a manufacturing method of a no-glue cosmetic brush according to the embodiment includes the steps of forming a shape of a brush hair 10 by using a plurality of hair members (S10), providing a fusion portion 20 by applying heat to a lower end of the shaped brush hair 10 (S20), processing the brush hair in a desired shape by pressing a hair fixing tube 30 in a region to which the fusion portion 20 is inserted (S30); and coupling the brush hair 10 to the hair fixing tube 30 by pressing the hair fixing tube 30 after inserting the brush hair 10 to the hair fixing tube 30 (S40).

[0027] The step (S10) of forming the shape of the brush hair 10 by using the plurality of hair members is a step of gathering the plurality of hair members and providing an upper portion having a round shape, as illustrated in FIG. 2.

[0028] The step (S20) of providing the fusion portion 20 by applying heat to the lower end of the shaped brush hair 10 is a step of providing the fusion portion 20 by applying heat to the lower end of the brush hair 10 as illustrated in FIGS. 2 and 3.

[0029] Like the embodiment, when the fusion portion 20 is provided at the lower end of the brush hair 10, the fusion portion 20 may serve as one position fixing means. As a result, when the brush hair 10 provided with the fusion portion 20 is inserted to the hair fixing tube 30, the fusion portion 20 is engaged and supported on an inner wall of the hair fixing tube 30 to be positioned and fixed, and thus, there is an advantage of omitting a process of adjusting the position unlike a conventional method using a glue.

[0030] In the embodiment, the fusion portion 20 may be provided with a diameter smaller than the upper portion of the brush hair 10 and provided by thermal fusion.

[0031] The step (S30) of processing the brush hair in a desired shape by pressing the hair fixing tube 30 in the region to which the fusion portion 20 is inserted is a step of providing the brush hair in a desired shape by pressing one side portion, for example, an upper portion of the hair fixing tube 30, as illustrated in FIG. 3.

[0032] In the embodiment, a first pressing portion 31 is provided by pressing the hair fixing tube 30 and the upper portion of the hair fixing tube 30 may have various known shapes such as a circular or elliptical shape depending on a pressing degree of the first pressing portion 31.

[0033] The step (S40) of coupling the brush hair 10 to the hair fixing tube 30 by pressing the hair fixing tube 30 after inserting the brush hair 10 to the hair fixing tube 30 is a step of coupling the brush hair 10 to the inside of the hair fixing tube 30 by pressing an outer wall of the hair fixing tube 30 while the fusion portion 20 is inserted into the hair fixing tube 30 by a pressing means including a press machine, as a final step of the embodiment. In this step, a second pressing portion 32 illustrated in FIG. 6 may be provided.

[0034] Like the embodiment, the fusion portion 20 is provided in the brush hair 10, the first pressing portion 31 and the second pressing portion 32 are sequentially provided in the hair fixing tube 30, and then the brush hair 10 is coupled to the hair fixing tube 30 without using a glue, thereby obtaining an almost similar result value to an existing intensity. In addition, the brush is able to be manufactured by using shorter hair members than an existing product, thereby greatly reducing the costs required for the hair members.

[0035] As described above, according to the embodiment, the fusion portion is provided by applying heat to the lower end of the shaped brush hair and inserted to the hair fixing tube and then the hair fixing tube is pressed, so that the brush may be manufactured without using a glue.

[0036] As described above, the present invention is not limited to the embodiments described herein, and it will be apparent to those skilled in the art that various changes and modifications may be made without departing from the spirit and the scope of the present invention. Therefore, it will be understood that these changes and modifications are included in the appended claims of the present invention.
