Description

[Technical field]

[0001] The present invention relates to a cosmetic mascara that allows for precise application. [Background technology]

[0002] Generally, mascara is a well-known cosmetic used to decorate women's eye lashes to make them appear longer and thicker, thereby enhancing the beauty of the eyes.

[0003] A typical structure of such mascara is mainly composed of a container body in which the mascara liquid is contained, a handle that functions as a stopper for opening and closing the container body, a rod-shaped brush stand protruding from the lower part of the handle, and a brush attached to the brush stand.

[0004] The mascara container having such a structure is used by applying an appropriate amount of mascara to the brush by combining or separating the handle and the container body, and then rotating the brush to apply the mascara to the eyelashes.

[0005] These mascara cosmetics are manufactured to suit various functions such as adding volume to eyelashes (making eyebrows look fuller), curl (making the ends of eyebrows look lifted by curling them upwards), long lash (making eyebrows look longer) and clean (preventing eyebrows from clumping) depending on the length and shape of the brush bristles attached to the brush holder that extends from the handle.

[0006] To ensure this function, the brush must absorb the mascara liquid well. In this regard, Patent Document 1 discloses a mascara that improves the suction ability by improving the shape of the brush to give the eyelashes more volume, and Prior Art Document 2 discloses a mascara that similarly changes the shape of the brush to allow a certain amount of mascara liquid to remain on the brush bristles.

[0007] However, the brushes in Patent Documents 1 and 2 are made of injectable rubber or elastomer. However, these materials are relatively very soft, so even if the above-mentioned effects of volume or curl are realized, in the case of more sophisticated effects such as long lashes and clean lashes, it is difficult to make fine adjustments due to the characteristics of the soft brush. [Prior art documents] [Patent documents]

[0008] [Patent Document 1] Korean Registered Practical Application No. 20-0487706 (2018.10.24), Mascara {MASKARA} [Patent Document 2] Korean Registered Practical Application No. 20-0486386 (2018.5.10), Mascara {MASKARA} Summary of the Invention [Problem to be solved by the invention]

[0009] The present invention has been made to solve the problems of the prior art, and an object of the present invention is to provide a mascara that ensures the absorption of mascara liquid while allowing fine adjustments during makeup application. [Means for solving the problem]

[0010] According to one aspect of the present invention, there is provided a mascara comprising a first brush extending in one direction and a second brush extending in the other direction, the first brush and the second brush being made of different materials, the second brush comprising a plurality of second bristles connected by a line chamber, and the second bristles connected by the line chamber being overlapped and fixed by a fixing clip, the first brush being made of a material softer than the second brush.

[0011] Also, the fixing clip may be made of brass or stainless steel.

[0012] Also, the first brush may be made of a material including rubber or elastomer, and the second brush may be made of a material including PBT (Polybutylene terephthalate).

[0013] Also, the mascara may further include a base to which the second brush is combined, and the first brush may be injection molded in a state in which the base and the second brush are combined.

[0014] Also, the base may have an insertion opening, and the first brush may be injection molded with the second brush inserted into and coupled to the insertion opening.

[0015] Also, a projectile connected to the first brush may be formed to fill the insertion opening.

[0016] Also, the base may have an injection support portion formed on a lower side thereof.

[0017] Also, a lower portion of the first brush may be formed to surround the injection support part.

[0018] In addition, the first bristles constituting the first brush may be formed to have a larger average diameter than the second bristles constituting the second brush, and the second bristles may be formed to be harder than the first bristles.

[0019] Also, the mascara may further include a third brush extending upward, and the first brush and the third brush may be integrally injection molded. Effect of the Invention

[0020] The present invention provides a mascara that substantially realizes long lashes and clean effects by changing the brush material to achieve soft volume and curl through a relatively soft first brush and fine adjustment through a relatively hard second brush.

[0021] In addition, since the second bristles of the second brush are firmly fixed by the fixing clip, the peel strength of the second brush can be significantly improved even when the first brush is bonded by double injection molding. [Brief description of the drawings]

[0024] A mascara according to an embodiment of the present invention will now be described. Figure 1 is a perspective view of a mascara according to an embodiment of the present invention, Figure 2 is a perspective view showing the upper structure of the brush base in more detail in Figure 1, Figure 3 is a side view showing the upper structure of the brush base in more detail in Figure 1, Figure 4 is a rear view showing the upper structure of the brush base in more detail in Figure 1, Figure 5 is a top view showing the upper structure of the brush base in more detail in Figure 1, Figure 6 is a view showing the assembly structure of a mascara according to the present invention, and Figure 7 is an enlarged view of the upper part of region B in Figure 6.

[0025] 1, a mascara 1000 according to an embodiment of the present invention includes a first brush 100 and a second brush 200, and may further include a third brush 300 as shown in the figure. In this case, the first brush 100 is formed to extend in one direction, and the second brush 200 is formed to extend in the other direction.

[0026] However, the mascara 1000 according to the present embodiment is characterized in that the first brush 100 and the second brush 200 are made of different materials. Normally, mascara brushes are made of multiple bristles, and these bristles are generally molded as a single unit using an injection molding process of elastomer or a soft material. However, in the mascara 1000 according to the present embodiment, the first brush 100 is made of a softer material than the second brush 200.

[0027] At this time, the material of the first brush 100 contains rubber or elastomer for injection, while the material of the second brush 200 contains relatively hard PBT (Polybutylene terephthalate). As a result, the first brush 100 promotes volume and curl formation, while the hard second brush 200 allows for long lash formation and more precise cleaning.

[0028] More specifically, the mascara applied to the eyebrows by the first brush 100 can be easily spread outward by the action of the hard second brush, and therefore, even if a large amount of mascara is applied to the eyebrows, the cleaning action of removing it can be made smooth. Also, in this embodiment, the average diameter of the second bristles 210 is made larger than the average diameter of the first bristles 110 constituting the first brush 100, so the relatively thin second bristles 210 can more easily realize the long lashes and clean described above.

[0029] 2 to 6, the first brush 100 is made up of a plurality of first bristles 110. In this embodiment, the first bristles 110 are made up of left bristles 110a forming a row on the left side, middle bristles 110b forming a row in the middle, and right bristles 110c forming a row on the right side according to their positions.

[0030] At this time, the left bristles 110a, the middle bristles 110b and the right bristles 110c each have a first horizontal opening 120 between the bristles. The first horizontal opening 120 is formed narrow to absorb the mascara liquid by capillary action, so that when it touches the eyebrow, the mascara liquid falls off easily and is transferred to the eyebrow.

[0031] As explained in the prior art, in the prior art documents 1 and 2, holes are provided in the area corresponding to the first brush 100 to improve suction, but this prevents the right amount of mascara from being applied to the eyebrows, and instead causes excessive mascara to be applied to the eyebrows. Therefore, the first bristles 110 of this embodiment allow the right amount of mascara to be contained in the first horizontal opening 120.

[0032] Additionally, in order to further ensure the suction of mascara liquid, the mascara 1000 according to this embodiment further has a first vertical opening 130 formed in the first brush 100. In Fig. 2, the first vertical opening 130 is formed between the left bristles 110a and the middle bristles 100b (reference numeral 130a), and between the middle bristles 100b and the right bristles 100c. The space occupied by this first vertical opening 130 is further saturated with mascara liquid, so the suction of mascara liquid is not impeded.

[0033] Meanwhile, in Fig. 2, reference numeral 150 denotes the lower end of the first brush. The first brush 100 is combined with the second brush 200 by a double injection technique as described below, and the lower end 150 of the first brush is a part that is generated at this time.

[0034] The second brush 200 is made up of second bristles 210 which are made up of a plurality of bristles which are harder than the first bristles 110. Also, as shown in the figure, the second bristles 210 are arranged such that a group of bristles made up of a plurality of individual bristles are spaced apart from each other at equal intervals. At this time, the space between the bristles forms a second horizontal opening 220.

[0035] At this time, since the second bristles 210 are formed in a plurality of pieces, it is preferable that they are attached to each other to form a single unit. Therefore, the plurality of second bristles 210 are preferentially fixed in the line chamber 231. However, in the mascara according to this embodiment, heat is applied to the line chamber 231 during the double injection process, so the combined state of the plurality of second bristles 210 becomes floppy and the intervals between each bristles become crooked.

[0036] Therefore, in this embodiment, a fixing clip 232 made of brass or stainless steel is overlapped and fixed to a plurality of second bristles 210 connected to the line chamber 231. The fixing clip is open on the right side as shown in Fig. 7 and holds each of the second bristles 210 by the fixing force of the metal, so that even if heat is applied to the line chamber 231 during the double injection process, the interval between each bristles is kept constant and the initial connection state is maintained.

[0037] Also, as shown in Fig. 7, the fixing clip 232 is formed in a shape of a plate folded in half or an ellipse with one side open. However, if the fixing clip 232 is sized to be inserted into the insertion opening 411, it can be said that slight differences in its shape are irrelevant. Also, in this case, it is preferable that the fixing clip 232 has a width similar to the width of the insertion opening 411. In this embodiment, the second brush 200 is fixed to the first brush 100 by double injection, but if the insertion opening 411 is formed small, the bonding force of the second brush 200 may be weak. Therefore, if the fixing clip 232 is inserted into the insertion opening 411 and sandwiched and bonded, the bonding force of the second brush 200 can be increased even if the second brush 200 is covered by a relatively thin injection material by double injection.

[0038] Meanwhile, in this embodiment, the material of the second brush 200 is harder than the first brush 100, so if the gap between them is narrow, the eyebrows may slip through and not be able to come out during fine eyebrow adjustment. Therefore, in this embodiment, the material of the second brush 200 is harder than the first brush 100, so the second horizontal opening 220 is formed in the second brush 200, and the eyebrows do not stick to the second brush 200, so that smooth brushing can be performed.

[0039] Meanwhile, the second bristles 210 have a plurality of individual bristles fixed by a second bristles connecting member 230. For this purpose, it is preferable that the second bristles connecting member (reference numeral 230 in FIG. 6) is formed of two flat plates facing each other, and the plurality of individual bristles are inserted between the two flat plates, and the two flat plates are thermally fused to complete the second brush 200.

[0040] Meanwhile, the third brush 300 is formed to gently and finely adjust the eyebrows. In this case, the third brush 300 is injection molded integrally with the first brush 100. The third brush 300 includes third bristles 310 and third vertical openings 320. In this case, the third bristles are formed with three individual bristles in the drawing, but the number is not limited. Also, it is preferable to form the number of third vertical openings 320 small for soft and fine adjustment.

[0041] The brush holder 400 includes a base 410 supporting the first brush 100 and the second brush 200, an extension 440 connected to the base 410, and a plug insert 450 closing the extension 440 and connecting it to a cap of a finished mascara product.

[0042] At this time, an insertion opening 411 penetrating the base 410 is formed. The second brush 200 is inserted into the insertion opening 411. At this time, the insertion opening 411 is formed such that the width of the opening is smaller on one side than on the other side, and the second brush 200 is inserted so that the second bristles 210 are exposed to the outside, but the second bristles coupling member 230 is formed so that it does not slip out to the outside in the same direction.

[0043] Meanwhile, a connecting part 420 and an injection support part 430 are formed at the lower end of the base 410. The connecting part 420 is a part formed with a cross-sectional area larger than that of the base 410 so as to be extended to the extension part 440 described above. Also, the first brush 100 and the third brush 300 according to this embodiment are formed by double injection after the base 410 and the second brush 200 are combined as described above. At this time, the injection support part 430 may be formed to have a vertical width as shown in FIG. 6. This improves the strength of the first brush 100, which is soft. At this time, an injection corresponding part 151 is formed at the lower part of the first brush 100, which is double injected, so as to surround the injection support part 430.

[0044] In addition, when forming the second brush 200, the composite of the second bristles 210 and the second bristle binding member may not be able to fill all of the insertion opening 411. Therefore, when forming the first brush 100 by injection molding, the injection material connected to the first brush can fill the portions of the insertion opening that are not completely filled, thereby further improving the peel strength and durability of the first brush 100.

[0045] In this manner, those skilled in the art will appreciate that the present invention may be embodied in other specific forms without departing from the technical spirit or essential characteristics of the present invention. In addition, the present specification and drawings disclose preferred embodiments of the present invention, and although specific terms are used, these are used in a general sense only to easily explain the technical contents of the present invention and to aid in the understanding of the invention, and are not intended to limit the scope of the present invention. It is obvious to those skilled in the art to which the present invention pertains that other modifications based on the technical ideas of the present invention can be implemented in addition to the embodiments disclosed herein.
