Description

TECHNICAL FIELD

The present invention relates to a cosmetic mascara capable of precise touch.

BACKGROUND ART

In general, a mascara is well known as a cosmetic product used to accentuate the beauty of women's eyes by making their eyelashes (eye lashes) look longer and darker.
The typical structure of this mascara is mainly composed of a container body for containing mascara liquid, a handle with a stopper function for opening and closing the container body, a rod-shaped brush rod protruding from the lower part of the handle, and a brush formed on a brush rod.
A mascara container with this structure is used by applying an appropriate amount of mascara liquid to the brush by combining or separating the handle and the container body, and then applying the mascara liquid to the eyelashes while rotating the brush.
These mascara cosmetics are designed to suit various functions such as volume (Volume: the effect of making the eyebrows look voluminous), curl (Curl: the effect of rolling the tip of the eyebrows upward), long lash (Long lash: the effect of making the eyebrows look longer), and clean (Clean: the effect of preventing the eyebrows from clumping) for the eyelashes, depending on the length and shape of the brush hair provided on the brush rod extended from the handle.
In order to secure this function, first of all, the brush must be able of retaining the mascara liquid well. Therefore, prior art document 1 discloses a mascara that can further impart a sense of volume to the eyelashes by further improving the shape of the brush to further improve the above retention, and prior art document 2 similarly describes a mascara that changes the shape of the brush so that more than a certain amount of mascara liquid remains in the hair of the brush.
However, the brushes in the prior art documents 1 and 2 are formed of injectable rubber or elastomer. However, since these materials are relatively soft, there is a disadvantage that fine adjustment is difficult due to the nature of soft brushes in the case of long lash and clean, which are more sophisticated effects, even if the effect of bullium or curl is achieved among the above effects.

Hereafter, the mascara according to an embodiment of the present invention will be described. FIG. 1 is a perspective view of the mascara according to an embodiment of the present invention, FIG. 2 is a perspective view illustrating an upper structure of the brush rod in more detail in FIG. 1 , FIG. 3 is a side view illustrating an upper structure of the brush rod in more detail in FIG. 1 , FIG. 4 is a rear view illustrating an upper structure of the brush rod in more detail in FIG. 1 , FIG. 5 is a top view illustrating an upper structure of the brush rod in more detail in FIG. 1 , and FIG. 6 is a diagram illustrating a coupling structure of the mascara according to the present invention.
First of all, referring to FIG. 1 , the mascara (1000) according to one 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. At this time, the first brush (100) is formed by extending in one direction, and the second brush (200) is formed by extending in the other direction.
However, the mascara (1000) according to one embodiment is characterized by the fact that the materials of the first brush (100) and the second brush (200) are formed differently. Normally, the brush of the mascara consists of a plurality of hairs (
), which are generally molded integrally with an elastomer or soft injection form. However, the mascara (1000) according to one embodiment is formed in which the material of the first brush (100) is softer than the material of the second brush (200).
At this time, the material of the first brush (100) includes a rubber or an elastomer for injection, but the material of the second brush (200) includes a relatively hard PBT (polybutylene terephthalate). Accordingly, volume formation and curl formation can be performed with the first brush (100), and long lashes formation and clean work can be performed more precisely by using the second brush (200), which is hard.
More specifically, the mascara liquid already applied to the eyebrows by the first brush (100) can be easily spread outward by the action of the second brush which is hard, and furthermore, even when a large amount of mascara liquid is applied to the eyebrows, the cleansing action of removing it can be smoothly performed. Also, in this embodiment, since the average diameter of the second hair (210) is formed larger than the average diameter of the first hair (110) constituting the first brush (100) in this case, it is possible to more easily implement the long lash and clean described above with the second hair (210) which is relatively thin.
Referring to FIG. 2 to FIG. 6 , the first brush (100) consists of a plurality of first hairs (110). Also, in this embodiment, the first hair (110) consists of a left hair (110 a) forming a row from the left, a middle hair (110 b) forming a row from the middle, and a right hair (110 c) forming a row from the right according to its position.
At this time, the left hair (110 a), middle hair (110 b), and right hair (110 c) each have a first horizontal opening (120) between the hair and the hair. The first horizontal opening (120) is narrowly formed to retain the mascara liquid according to the capillary phenomenon, and when it touches the eyebrows, the mascara liquid is easily removed and transferred to the eyebrows.
As described in prior art, the prior art literature 1 and 2 have holes to improve the retention of the mascara liquid in the part corresponding to the first brush (100), which rather prevents an appropriate amount of mascara liquid from being applied to the eyebrows and causes excessive mascara fluid to be applied to the eyebrows. Therefore, the first hair (110) according to this embodiment allows an appropriate amount of mascara liquid to be retained in the first horizontal opening (120).
Also, in order to further guarantee the retention of the mascara liquid, the mascara (1000) according to this embodiment has a first vertical opening (130) further formed in the first brush (100). The first vertical opening (130) is formed between the left hair (110 a) and the middle hair (100 b) in FIG. 2 (reference numeral 130 a), and is formed between the middle hair (100 b) and the right hair (100 c). Since the space occupied by this first vertical opening (130) is further impregnated with mascara liquid, the retention of the mascara liquid is not impaired.
Meanwhile, in FIG. 2 , a reference numeral 150 is the lower part of the first brush. The first brush (100) is double injected while being combined with the second brush (200) using a double injection technique as described below, and the lower part of the first brush (150) is the part generated together at this time.
The second brush (200) consists of a second hair (210) composed of a plurality of hairs that are harder than the first hair (110). Also, in the second hair (210), as shown, the first group of hairs composed of a plurality of individual hairs are arranged at equal intervals from each other. At this time, the spaced space forms a second horizontal opening (220).
On the other hand, in this embodiment, the material of the second brush (200) is harder than the first brush (100), so if the spacing is tight, the eyebrows may not come out during fine adjustment of the eyebrows. Therefore, in this embodiment where the material of the second brush (200) is harder than the first brush (100), such a second horizontal opening (220) is formed on the second brush (200), so that brushing may be smoothly performed without sticking to the eyebrows.
Meanwhile, in the second hair (210), a plurality of individual hairs are fixed by the second hair (230). To this end, it is desirable that the second hair coupling member (see reference numeral 230 in FIG. 6 ) may be formed of two flat plates facing each other, and may be placed therebetween to thermally fuse the two flat plates to complete the second brush (200).
Meanwhile, a third brush (300) is formed to smoothly fine-tune the eyebrows. In this case, the third brush (300) is integrally injection-molded with the first brush (100). The third brush (300) includes a third hair (310) and a third vertical opening (320). In this case, in the drawing, there are three individual hairs of the third hair, but it is natural that the number is not limited. Also, it is desirable to form a small number of third vertical openings (320) for smooth fine control.
The brush rod (400) consists of a base (410) supporting a first brush (100) and a second brush (200), an extension (440) connected to the base (410), and a stopper insert (450) that closes the extension (440) and connects to the lid of a finished mascara product.
At this time, an insertion opening (411) penetrating the base (410) is formed in the base (410). A second brush (200) is inserted into the insertion opening (411). In this case, the insertion opening (411) is formed so that the opening width on the other side is smaller than one side, so that a second brush (200) is inserted so that the second hair (210) is exposed to the outside, but the second coupling member (230) does not fall outward in the same direction.
Meanwhile, a connection part (420) and an injection support (430) are formed at the bottom of the base (410). The connection part (420) is a portion whose cross-sectional area is formed larger than the base (410) so as to extend with the extension (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. In this case, the injection support (430) can be formed to have a vertical width as illustrated in FIG. 6 . Accordingly, the use strength of the soft first brush (100) is improved. At this time, an injection counterpart (151) corresponding to surround the injection support (430) is formed on the lower part of the double injected first brush (100).
Also, when forming a second brush (200), the composite of the second hair (210) and the second hair member may not fill all of the above insertion openings (411). Therefore, when the first brush (100) is formed by injection, the injection material connected to the first brush can fill the unfilled portion of the insertion opening, thereby further improving the peeling strength and durability of the first brush (100).
Hereafter, the mascara according to second embodiment of the present invention will be described. FIG. 7 is a perspective view of a mascara according to second embodiment of the present invention.
the mascara (2000) according to the second embodiment of the present invention, the first hair (110′) is composed of individual hairs having only one row. Accordingly, the number of first horizontal openings (120′) is also reduced by about ⅓ compared to that of the first embodiment. Also, in the second embodiment, the aforementioned first vertical opening (130) is absent. Therefore, it is possible to perform more precise makeup with a small amount of mascara liquid.
Hereafter, the mascara according to third embodiment of the present invention will be described. FIG. 8 is a perspective view of a mascara according to third embodiment of the present invention.
Referring to FIG. 8 , in the mascara (3000) according to the third embodiment, the structure of the second hair (210′) is formed differently. As described above, in the first embodiment, the second horizontal opening (220) is formed to help the eyebrows escape smoothly when a clean process or the like is performed. In the third embodiment, the second horizontal opening (220′) is also formed to help the eyebrows escape smoothly, but for long lashes, mascara needs to hold the eyebrows until the end.
Accordingly, in the third embodiment, a second horizontal opening (220′) is formed between a group of hairs constituting the second hairs (210′), but individual hairs constituting a group of hairs form an angle to extend. Accordingly, as shown in FIG. 8 , there is almost no spaced area at the end of the second brush (220′). Therefore, it is possible to maximize the long lash effect by holding the eyebrows that have already started prolapse to the end with a light force.
Hereafter, the mascara according to fourth embodiment of the present invention will be described. FIG. 9 is a perspective view of a mascara according to fourth embodiment of the present invention. For more detailed uses than the third embodiment, it shows that the structure of the second hair (210″) is composed of individual hairs (210 a″) in one direction and individual hairs (210 b″) in the other direction extended while having an angle therewith. In this case, as in the third embodiment, the eyebrows that have already started prolapse are held to the end with a light force, so that the long lash effect can be maximized.
In this way, a person of ordinary skill in the art to which the invention pertains can understand that the present invention can be implemented in a different specific form without changing its technical ideas or essential features.
Furthermore, the present specification and drawing disclose desirable embodiments of the present invention, and although specific terms are used, they are only used in a general sense to easily explain the technical contents of the present invention and help understand the invention, and not to limit the scope of the present invention. In addition to the embodiments disclosed herein, it is obvious to a person skilled in the art that other modified examples based on the technical ideas of the present invention may be implemented.
