Description

[Technical field]

[0001] The present invention relates to a mascara brush and a manufacturing method thereof, and more particularly to a mascara brush manufactured by bonding filaments formed in various patterns to a body of a mascara brush and a manufacturing method thereof. [Background technology]

[0002] Generally, mascara is a type of cosmetic used by women, and refers to applying various colors of mascara to eyelashes using a brush to make the eyes stand out. Mascara is generally composed of a container in which the mascara liquid is stored, a handle for opening and closing the container, a rod-shaped support protruding from the bottom of the handle, and a brush attached to the support. The handle and the container can be combined or separated to apply the mascara liquid to the brush.

[0003] Mascara brushes, which are structures made up of such a brush base and brush, are manufactured to suit various functions such as adding volume to eyelashes (volume: the effect of making eyebrows look fuller), curl (the effect of curling the ends of eyebrows upwards), long lash (long lash: the effect of making eyebrows look longer), and clean (the effect of preventing eyebrows from becoming clumpy) depending on the length and shape of the bristles.

[0004] Such a mascara brush must be able to apply a viscous mascara liquid evenly to the eyelashes, and must also have a combing function to prevent the eyelashes from tangling with each other.

[0005] Mascara brushes use mascara liquid to fix eyelashes in various patterns, but even if the brush is positioned regularly, the brushing effect of the mascara is reduced. Also, even in the case of one-piece mascara brushes, it is very difficult to make an irregularly shaped brush, and assembling a number of brushes to make an irregularly shaped brush increases the manufacturing cost.

[0006] In addition, conventional mascara brushes are formed with long bristles and irregularly arranged bristles, and in this case, the brushing function of the brush is insufficient, and the mascara applied to the eyelashes often aggregates in certain areas, which can hinder the aesthetic sense of the eyelashes after applying mascara.

[0032] FIG. 1 is a perspective view of a first embodiment of the brush bar according to the present invention. As shown in the drawing, the brush bar 11 is made of one body consisting of a connecting body 11-1, one side of which is connected to a handle 2, and a slotted body 11-2, in which a slot 11-3 is formed, into which an artificial eyebrow 15 is inserted. In the drawing, the brush bar 11 is shown as a cylinder having a circular cross section, but it may also be formed as an oval cylinder or a polygonal barrel shape, and such modifications are merely simple design modifications for those skilled in the art to which the present invention pertains. FIG. 2 is a drawing of the first embodiment of the brush bar according to the present invention with the addition of a slot. As shown in the drawing, two slots 11-3a and 11-3b are shown to be formed, but multiple slots may be formed.

[0033] When multiple slots 11-3a, 11-3b are formed, the brush 15 can be formed in multiple layers, making it easier and faster to apply mascara to the eyebrows. When multiple slots 11-3 are formed, multiple layers of the brush 15 are formed, which has the advantage of making it easier and faster to apply mascara to the eyebrows.

[0034] 3 is a perspective view of a second embodiment of a brush bar 11' according to the present invention. As shown in the drawing, the brush bar 11' is composed of a connecting body 11-1', one side of which is connected to the handle 2, a flat slotted body 11-2' extending from the other side of the connecting body 11-1', and a slot 11-3' in the length direction of the slotted body 11-2'.

[0035] In the above drawings, the brush bar connecting body 11-1' is illustrated as having a circular cross section, but the cross section may be oval or polygonal, and such details are merely design modifications that will be apparent to those skilled in the art to which the present invention pertains.

[0036] For example, when the cross section is rectangular, all the regions are formed with rectangular connecting body 11-1' and slot body 11-2', and a certain length of slot 11-3' is formed. A filament formed in a certain pattern is inserted into slot 11-3', and a brush 15 is formed that is integrally connected to brush bar 11' by applying adhesive or by vibration welding or heat welding to form brush bar part 10'. Vibration welding includes ultrasonic welding and high frequency welding. Figure 4 shows the addition of a slot to brush bar 11' of the second embodiment. As shown in the drawing, two slots 11-3a' and 11-3b' are shown, but multiple slots can be formed as long as the thickness allows. When multiple slots 11-3' are formed, a multi-layered brush 15 is formed, which has the advantage that it is quick and easy to apply mascara to eyebrows.

[0037] FIG. 5 is a perspective view of a third embodiment of the brush bar 11" according to the present invention. As shown in the drawing, the brush bar 11" comprises one body 11-2a" formed in a semi-cylindrical or flat shape, another body 11-2b" formed in a shape symmetrical to the one body 11-2a", and a folding part 11-4" in which the one body 11a-2" and the other body 11-2b" are integrally connected and foldable. The one body 11-2a" and the other body 11-2b" are connected to the one connecting body 11-1a" and the other connecting body 11-2b" by a folding part 11-4". When the one-side body 11-2a" and the other-side body 11-2b" are folded based on the folding portion 11-4", the gap between the one-side body 11-2a" and the other-side body 11-2b" becomes a slot 11-3". Artificial eyebrows formed in a certain pattern are inserted into the slot 11-3", and the brush 15 is formed and integrally connected to the brush bar 11" by applying adhesive or by vibration welding or heat welding to form the brush bar portion 10".

[0038] FIG. 6 is a perspective view of a fourth embodiment of a brush bar 11"' according to the present invention. As shown in the drawing, the brush bar 11"' comprises an upper body 11-2a"' made of a flat plate on one side thereof, and a string insertion groove 11-4a"' into which a string 14' having a filament bound thereto is inserted in the center of its length, and a lower body 11-2b"' made of a flat plate on one side thereof which is symmetrical to the upper body 11-2a'', and a slot 11-3"' is formed by overlapping the flat portions of the upper body 11-2a"' and the lower body 11-2b"'. In the brush bar 11"' of the above embodiment, the string insertion grooves 11-4a"' and 11-4b"' may not be formed, and a certain pattern of brushes may be placed directly on the flat plate between the upper body 11-2a"' and the lower body 11-2b"'. An upper connecting body 11-1a''' is integrally formed with one side of the upper body 11-2a''', and a lower connecting body 11-1b''' is integrally formed with one side of the lower body 11-2b'''. The upper and lower connecting bodies 11-1a''', 11-1b''' are connected to the brush bar connecting portion 3 of the handle 2.

[0039] FIG. 7 shows that a central body 11-2c''' has been added to add a slot to the brush bar 11''' of the fourth embodiment. As shown in the drawing, central body 11-2c''', which is formed with flat plates on both sides, has string insertion grooves 11-4c''' formed on the top and bottom, and two slots 11-3a''', 11-3b''' are formed by overlapping the flat plate portion of upper body 11-2a''' with the flat plate portions of central body 11-2c'' and lower body 11-2b'''. Of course, if another central body 11-2c''' is added, multiple slots 11-3''' can be formed.

[0040] When multiple slots 11-3''' are formed, a multi-layer brush 15 is formed, which has the advantage that applying mascara to the eyebrows can be made quick and easy.

[0041] In the above-mentioned embodiment, the upper body 11-2a'' having one side made of a flat plate, the lower body 11-2b''' having one side made of a flat plate so as to be overlapped with the upper body, and the central body 11-2c'' having flat plates on both sides do not have the string insertion grooves 11-4a''', 11-4b'', and 11-4c''', and the filament can be directly inserted between the upper body and the central body and between the central body and the lower body.

[0042] FIG. 8 is a perspective view of a first embodiment of a method for manufacturing a mascara brush according to the present invention. FIG. 8 illustrates the first embodiment of a brush bar 11. As shown in the drawing, the method for manufacturing a mascara brush includes the steps of (a) attaching filaments 151 to an adhesive tape 14 to form a filament 151 in a certain pattern, (b) inserting the filaments 151 in the certain pattern into the slots 12, (c) forming a brush 15 by injecting adhesive into the slots 12 after the filaments 151 in the certain pattern have been inserted into the slots 12, or by vibration or heat fusing the slots, and (d) cutting and removing the portion of the brush bar 11 on which the brush 15 is formed, to which the adhesive tape 14 is attached. In the step (a) shown in FIG. 8(a), the filaments 151 are first arranged to have a certain shape to form the brush 15. Generally, a certain shape of filament arrangement is formed on a lower adhesive tape, and when the arrangement is completed, an upper adhesive tape is attached to the upper part of the filament to fix the shape of the filament 151. Next, step (b) shown in FIG. 8(b) is a step of inserting filaments 151 in a certain pattern into slots 11-3 of brush bar 11.

[0043] The filament 151 of a certain pattern inserted into the slot 11-3 is fixed within the slot 11-3. width 8(c) is a step of fixing the filament 151 inserted in the slot 11-3.

[0044] To fix the filament 151, an adhesive is poured into the slot 11-3, or a vibration fusion machine 20 is used, or a heat fusion machine 20 is used to fuse the slot portion.

[0045] Vibration welding includes ultrasonic welding and high frequency welding, by which the filament 151 is fixed to form the brush 15. In the case of adhesives, different materials may be used, but in the case of vibration welding or heat welding, it is preferable that the brush bar 11 and the brush 15 are made of the same material. This is because the same frequency and heat are applied to each other during vibration welding or heat welding. In this embodiment, the brush bar 11, 11', 11" of Figures 1 to 5 can be used. Even when the slots 11-3a, 11-3b, 11-3a', 11-3b', 11-3a", 11-3b" are formed in multiple layers as in Figures 2 and 4, the same process can be carried out by inserting the filament 151 in a certain pattern. Step (d) of Figure 8(d) shows the step of removing the adhesive tape 14 portion from the brush bar 11. When the adhesive tape 14 portion is removed, one side is usually made to be tapered toward the end when the filament is made, but the other side may not have a tapered end because it has been cut by a cutter. However, since the shapes of the ends of the brush at both ends are different, the originally tapered end can be used to apply mascara finely, or the part that was originally tapered can be used to apply mascara finely. In order to apply a large amount of mascara, the part where the cutting surface is formed can be used, which has various advantages and the advantage of being able to form brushes of different shapes. Next, step (e) shown in Fig. 8 (e) may further include a step of cutting the end of the brush 15 into a certain shape to form a cutting line 15-1 of a certain shape at the end of the brush 15 when the brush 15 is fixed and attached to the brush bar 11. The cutting line 15-1 may be made in various ways as shown in Fig. 11. Also, curling may be formed without cutting the end. Also, curled filaments may be used, and such a conversion may be considered to be a simple design change in the technical field to which the present invention pertains.

[0046] FIG. 9 shows a second embodiment of the manufacturing method. The second embodiment includes the steps of (a) forming a filament 151' in a certain pattern by knitting a knot with a filament 151' on a string 14', (b) inserting the filament 151' in the certain pattern into the slot 11-3, (c) forming a brush 15 by injecting adhesive into the slot 11-3 into which the filament 151' in the certain pattern has been inserted, or by vibration fusing or heat fusing the slot, and (d) cutting and removing the part of the string where the knot has been knitted from the brush bar 11 on which the brush 15 has been formed. As shown in FIG. 9(a), first, a filament 151' is knitted in a certain shape on the string 14' to form a filament 151' in a certain pattern. The knot formed on the string can be formed by knitting the filament, tying the filament, or attaching the filament to the string 14'. Next, FIG. 9(b) shows step (b) of inserting the filament 151', which is woven in a certain pattern of knots in the brush bar 11, into the slot 11-3. The brush bar used in step (b) can be the brush bar of FIG. 1 to FIG. 5. The same steps are applied when the slots 11-3a, 11-3b, 11-3a', and 11-3b' are made in multiple layers as in FIG. 2 and FIG. 4, since it is sufficient to insert the filament 151' into the slot. FIG. 9(c) shows step (c) of fixing the filament 151 to the brush bar 11 when the filament 151' is inserted into the slot 11-3. For this, the slot 11-3 is coated with adhesive, or the slot 11-3 is fused with a vibration fusion machine 20, or fused with a heat fusion machine 20 to fix the filament 151'. Vibration fusion includes ultrasonic fusion and high-frequency fusion. The filament 151' inserted into the slot 11-3 is fixed to form the brush 15. Next, FIG. 9(d) shows a step of cutting the portion of the string 14' that secures the filament 151' once the filament 151' has been inserted into the brush bar 11 (d).Figure 9(e) shows that the method further includes the step of (e) cutting the end of the brush 15 in a specific shape to form a cutting line 15-1 at the end of the brush 15 when the brush 15 is fixed to the brush bar 11. The cutting line 15-1 can be made in various ways, such as the shape shown in Figure 11. Also, curling can be formed without cutting the end. Also, a mascara brush can be manufactured according to the above process using the curled filament.

[0047] FIG. 10 shows a third embodiment of the manufacturing method. The third embodiment uses a brush bar 11 having an upper body 11-2a"' in which a string insertion groove 11-4a"' into which a string 14" is inserted is formed in the center of the length direction, a lower body 11-2b"' formed in a shape symmetrical to the upper body 11-2a"', an upper connecting body 11-1a"' formed integrally with the upper body 11-2a"' on one side of the upper body 11-2a"', and a lower connecting body 11-1b"' formed integrally with the lower body 11-2b"' on one side of the lower body 11-2b"'. The third embodiment includes the steps of (a) attaching a filament 151" to a string 14" or weaving a knot to form two parts with the filament 151" in a specific pattern, and (b) forming the filament 151" in the specific pattern. (c) inserting the string 14" attached with the adhesive into a string insertion groove 11-4b"' formed in the lower body to place the filament 151" of the fixed pattern on the lower body 11-2b"', and placing the upper body 11-2a"' on the lower body 11-2b"' on which the filament 151" of the fixed pattern is placed; and (d) injecting adhesive into the upper body 11-2a"' and the lower body 11-2b"' on which the filament 151" of the fixed pattern is placed, or by vibration fusing or heat fusing the upper body and the lower body to form the brush 15". FIG. 10(a) shows the step (a) of forming a fixed pattern by knotting the filament 151" into the string 14".

[0048] The fixed pattern is formed in two parts so that they can be attached to each other to form a pattern on both sides. FIG. 10(b) shows the step (b) of adhering string 14" so that a fixed pattern filament 151" is formed on both sides.
