MASCARA BRUSH HAVING TORNADO-SHAPED BRISTLE

Abstract

A mascara brush having a tornado-shaped bristle includes a bristle and a core. A root of the bristle is provided on the core, and a free end of the bristle is provided away from the core. There is at least one bristle. A centerline of the bristle intersects with an axis of the core in a non-perpendicular manner. By providing an included angle between the centerline of the bristle and the axis of the core, the bristle is inserted between eyelashes more easily. As the bristle is not perpendicular to the axis of the core, a cross section of the whole mascara brush is reduced. While the length of the bristle remains the same, the opening of a mascara bottle is reduced. The new mascara brush has the advantages of better application effect, more compact structure and better ease of eyelash combing.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0035] In order to understand the technical means of the present disclosure more clearly and implement the technical means according to contents in the specification, specific implementations of the present disclosure will be further described below in detail with reference to the accompanying drawings and embodiments. The embodiments described below are intended to illustrate the present disclosure, rather than limit the scope of the present disclosure.

Embodiment 1

[0036] As shown in FIGS. 1-7, the present disclosure provides a mascara brush having a tornado-shaped bristle, including a bristle 1 and a core 2. A root of the bristle 1 is provided on the core 2, and a free end of the bristle 1 is provided away from the core 2. There is at least one bristle 1. A centerline of the bristle 1 intersects with an axis of the core 2 in a non-perpendicular manner. In the embodiment, the centerline of the bristle 1 is oblique to the axis of the core 2. The positional relationship between the bristle 1 and the core 2 is an exemplary illustration, rather than a specific limitation to the present disclosure.

[0037] In a specific implementation, by providing an included angle between the centerline of the bristle 1 and the axis of the core 2, the bristle 1 is inserted between eyelashes more easily. As the bristle 1 is not perpendicular to the axis of the core 2, a cross section of the whole mascara brush is reduced. While the length of the bristle 1 remains the same, the opening of a mascara bottle is reduced. The mascara brush has the advantages of better application effect, more compact structure and better ease of eyelash combing.

[0038] Optionally, the centerline of the bristle 1 is an arc line. Included angles between all the bristles 1 and the axis of the core 2 are identical in a direction. The core 2 is rod-like, with a rectangular side section. The bristle 1 is provided at a first end of the core 2. A fixing mechanism is provided at a second end of the core 2. A cross section of the core 2 is circular or elliptical. In the embodiment, the cross section of the core 2 is circular. A single row of bristles 1 are spaced apart along the axis of the core 2, or multiple rows of bristles 1 are spaced apart along the axis of the core 2 and spaced apart in a tornado-shaped manner along a circumferential direction of the core 2. When there are multiple rows of bristles 1, the bristles 1 are arranged into 14 rows, 16 rows or 18 rows, etc. It is noted that the row number into which the bristles 1 are arranged is an exemplary illustration, rather than a specific limitation to the present disclosure. In the embodiment, there are 16 rows of bristles. Two adjacent rows of bristles 1 are parallel to each other or staggered from each other along the axis of the core 2. In the embodiment, the two adjacent rows of bristles 1 are staggered from each other.

[0039] In a specific implementation, by staggering the two adjacent rows of bristles 1 from each other, a better combing effect can be achieved. Optionally, at least two rows of bristles 1 are provided on the core 2, where at least one row of bristles 1 are the bristles 1 formed into the included angles with the axis of the core 2, and centerlines of remaining ones of the bristles 1 are perpendicular to the axis of the core 2.

[0040] Optionally, an included angle between the centerline of the bristle 1 and the axis of the core 2 is in a range of (0°, 45° ], such as 3°, 5°, 8°, 10°, 15°, 30°, 40° or 45°. In the embodiment, the included angle between the centerline of the bristle 1 and the axis of the core 2 is 5°. It is noted that the included angle between the centerline of the bristle 1 and the axis of the core 2 is an exemplary illustration, rather than a specific limitation to the present disclosure.

[0041] Optionally, two sides of the same row of bristles 1 are defined as a first side and a second side, respectively. The bristle 1 at the first side and the bristle 1 at the second side are higher than the bristle 1 in a middle. The bristle 1 at the first side is as high as the bristle 1 at the second side, or the bristle 1 at the first side is not as high as the bristle 1 at the second side. In other words, the bristle 1 at the first side has a height of H1, the bristle 1 at the second side has a height of H2, and the bristle 1 in the middle has a height of H3, H1=H2>H3, or H1>H2>H3, or H2>H1>H3.

[0042] In the embodiment, the bristle 1 at the first side and the bristle 1 at the second side are higher than the bristle 1 in the middle, and the bristle 1 at the first side is not as high as the bristle 1 at the second side.

[0043] In a specific implementation, by providing the bristle 1 at the first side and the bristle at the second side to be higher than the bristle 1 in the middle, and the bristle 1 at the first side to be not as high as the bristle 1 at the second side, the mascara brush can be more suitable for shapes of the eyelashes to achieve the better combing effect. Optionally, centerlines of at least two of the bristles 1 are gathered to one point, or gathered to a circumference of one circle. In the embodiment, the centerlines of at least two of the bristles 1 are gathered to one point.

[0044] Optionally, a cross section of the bristle 1 is in at least one of a square shape, a cross shape, an I shape, a petaloid shape, an octagon, a rectangle, a rounded rectangle, a triangle, a convex trapezoid, a concave trapezoid, a circle and an ellipse. It is noted that the cross section of the bristle 1 is an exemplary illustration, rather than a specific limitation to the present disclosure. In the embodiment, the cross section of the bristle 1 is circular.

[0045] Optionally, the cross section of the bristle 1 is in a centrosymmetric shape or an axisymmetric shape. In the embodiment, the cross section of the bristle 1 is in the centrosymmetric shape.

[0046] Optionally, there are a same cross-sectional shape and a same cross-sectional area or different cross-sectional areas at different heights of the same bristle 1. In the embodiment, the cross section close to the root is greater than that close to the free end for the same bristle 1. In other words, any two cross sections at different heights of the same bristle 1 are identical, or, any two cross sections at different heights of the same bristle 1 are similar.

[0047] In a specific implementation, the cross section close to the root is greater than that close to the free end for the same bristle 1, such that the eyelashes can be guided to gaps between the bristles 1 more easily for combing. Optionally, a cross-sectional area of the bristle 1 from the root to a tip is decreased linearly.

[0048] In the embodiment, the mascara brush having a tornado-shaped bristle is manufactured by a process including integrated injection molding, such as injection molding, glue injection, or blow molding in a molding cycle. The bristle 1 and the core 2 are formed by integrated injection molding. It is noted that the mascara brush having a tornado-shaped bristle in the embodiment may further be manufactured by another process, which is not limited by the present disclosure.

[0049] In the embodiment, the mascara brush having a tornado-shaped bristle is made of a material including plastic or acrylonitrile-butadiene rubber. It is noted that the mascara brush having a tornado-shaped bristle in the embodiment may further be made of another material, which is not limited by the present disclosure.

Embodiment 2

[0050] As shown in FIGS. 8-11, Embodiment 2 improves upon Embodiment 1. In Embodiment 2, a cross section of the bristle 1 is in at least one of a square shape, a cross shape, an I shape, a petaloid shape, an octagon, a rectangle, a rounded rectangle, a triangle, an ellipse, a convex trapezoid and a concave trapezoid. It is noted that the cross section of the bristle 1 is an exemplary illustration, rather than a specific limitation to the present disclosure. The bristle 1 is twisted along a circumferential direction of its own axis. A twisted angle of the bristle 1 is in a range of (0°, 360° ], such as 30°, 60°, 90°, 180° or 270°. It is noted that the twisted angle of the bristle 1 is an exemplary illustration, rather than a specific limitation to the present disclosure. The bristle 1 is twisted entirely, the free end of the bristle is twisted, the root of the bristle is twisted, the middle portion of the bristle is twisted, or both the free end and the root of the bristle are twisted. It is noted that the twisted position of the bristle 1 is an exemplary illustration, rather than a specific limitation to the present disclosure. In the embodiment, the bristle 1 is twisted entirely.

[0051] In a specific implementation, as the bristle 1 is twisted along the circumferential direction of its own axis, the material such as a mascara is better loaded on the bristle 1. Meanwhile, the twisted bristle 1 is more suitable for the eyelashes, such that the eyelashes are attached on the bristle 1 more easily, a larger amount of the material can be dipped at one time, and the material is applied to the eyelashes more easily. Optionally, when the bristle 1 is in any one of the cross shape, the I shape and the octagon, a groove formed by a concave portion on the cross section of the bristle 1 is a spiral groove. In the embodiment, the cross section of the bristle is I-shaped.

[0052] In a specific implementation, with the spiral groove, the material can be loaded onto the bristle 1 more easily. Moreover, the eyelashes can also be embedded into the spiral groove for the better application effect.

[0053] Optionally, the bristle 1 is twisted clockwise along the circumferential direction of its own axis, or twisted counterclockwise along the circumferential direction of its own axis. In the embodiment, the bristle 1 is twisted counterclockwise along the circumferential direction of its own axis.

[0054] Optionally, side edges of the bristle 1 are located at outward protruding junctions between two lines of the cross section of the bristle 1. At least one of the side edges of the bristle 1 is twisted. A twisted angle of the side edge is in a range of (0°, 360° ], such as 30°, 45°, 60°, 90°, 180° or 270°. It is noted that the twisted angle of the side edge is an exemplary illustration, rather than a specific limitation in the present disclosure.

[0055] Optionally, all the side edges of the bristle 1 are twisted. Any two of the side edges are twisted in different angles, or any two of the side edges in a centrosymmetry are twisted in a same angle. In the embodiment, any two of the side edges in a centrosymmetry are twisted in a same angle.

[0056] The foregoing embodiments are preferred embodiments of the present disclosure and are described in detail with reference to the accompanying drawing. Various modifications or changes made by those skilled in the art to the above embodiments should fall within the protection scope of the present disclosure without departing from the essence of the present disclosure.
