CROSS REFERENCE TO THE RELATED APPLICATIONS
This application is based upon and claims priority to Chinese Patent Application No. 202211102744.5, filed on Sep. 9, 2022, the entire contents of which are incorporated herein by reference.
TECHNICAL FIELD
The present application relates to the field of makeup tools, and in particular to an applicator.
BACKGROUND
In the beauty industry, mascara has been widely used for eyelashes. When mascara is brushed to the eyelashes, an applicator is used essentially to apply the mascara. Using the existing applicator, it is a common practice to hold a brush handle and apply the bristles that were dipped into mascara to the eyelashes. Since the bristles can carry only a small amount of the cosmetic, the user needs to dip the cosmetic frequently for makeup. This is inconvenient and time-consuming.
SUMMARY
The present application provides an applicator to overcome the above-mentioned defects. A cavity is formed in the applicator. The cavity can carry a large amount of a cosmetic. Therefore, the present application improves a cosmetic carrying capacity of the applicator, makes a user dip the cosmetic from the cosmetic bottle less frequently, and achieves convenience in use and a higher makeup efficiency.
To solve the technical problems, the present application employs the following technical solutions.
An applicator includes a brush handle and at least two branches, where the inner walls of the at least two branches enclose a cavity, each of the branches includes at least two brush strips; first ends of the brush strips are fixedly connected to the brush handle; second end of the brush strips are free ends; two adjacent brush strips in each of the branches are fixedly connected through a connecting bridge; and protrusions are respectively arranged on the brush strips.
Optionally, the second ends of the brush strips extend straight along a central axis of the brush handle toward a direction away from the brush handle.
Optionally, each of the brush strips includes an outer surface and an inner surface that are opposite to each other; the protrusions are arranged on the outer surface; and the inner surfaces of the brush strips enclose the cavity.
Optionally, a longitudinal section of the outer surface of the brush strip is a wave-shaped structure.
Optionally, the longitudinal section of the outer surface of the brush strip is a single-peak structure, a dual-peak structure or a multi-peak structure.
Optionally, the peak structure is a leading peak, a tailing peak or a symmetrical peak.
Optionally, the inner surfaces of all brush strips are located at a same side of a cylindrical space or a polyhedral space; and an upper bottom surface, a lower bottom surface and any transverse section parallel to the upper bottom surface in the polyhedral space are regular polygons of a same structure.
Optionally, the outer surface of the brush strip and the inner surface of the brush strip have a same shape, and the outer surface of the brush strip is parallel to the inner surface of the brush strip.
Optionally, a distance from a junction P between the connecting bridge and the brush strip to the first end is L1, a distance from the junction P to the second end is L2, and L2 is less than or equal to L1.
Optionally, one row of the protrusions is arranged on the brush strip, the protrusion includes a root and a head, the root of the protrusion is connected to the outer surface of the brush strip, the head of the protrusion extends outward along a radial direction of the brush strip, the head of the protrusion serves as a free end, the protrusion is a truncated cone shaped structure, and a diameter of the root is greater than a diameter of the head.
The present application has the following beneficial effects:
According to the present application, the inner walls of the branches enclose the cavity. When the applicator is pulled out of a cosmetic bottle, not only the protrusions carry the cosmetic, but the cavity also stores the cosmetic more. During makeup, the cosmetic in the cavity is added to the protrusions through the free ends of the brush strips and gaps between the brush strips. Therefore, the present application greatly improves a cosmetic carrying capacity of the applicator, makes a user dip the cosmetic from the cosmetic bottle less frequently, and achieves convenience in use and a higher makeup efficiency.
2) The multiple brush strips are independent of each other. Only certain ends of the brush strips are connected to the brush handle, while the remaining parts of the brush strips are free. The brush strips are flexible in transverse, longitudinal and circumferential directions, for ease of flexible makeup. Furthermore, to achieve a higher strength of the brush strips, the brush strips in each branch are fixedly connected through the connecting bridge, and the connecting bridge is biased to the free ends of the brush strips. Therefore, while ensuring the strength of the brush strips, the present application achieves a certain flexibility of the brush strips to complete the makeup smoothly.

DETAILED DESCRIPTION OF THE EMBODIMENTS
The technical solutions in the embodiments of the present application are clearly and completely described below with reference to the embodiments of the present application. Apparently, the described embodiments are merely some rather than all of the embodiments of the present application. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present application without creative efforts should fall within the protection scope of the present application.
It should be noted that the terms “first”, “second”, and so on in the description and claims of this application and in the above accompanying drawings are intended to distinguish similar objects but do not necessarily indicate a specific order or sequence. It should be understood that the data used in such a way may be exchanged under proper conditions to make it possible to implement the described implementations of this application in sequences except those illustrated or described herein. Moreover, the terms “include”, “contain”, and any other variants mean to cover the non-exclusive inclusion, for example, a process, method, system, product, or device that includes a list of steps or units is not necessarily limited to those steps or units which are clearly listed, but may include other steps or units which are not expressly listed or inherent to such a process, method, system, product, or device.
Embodiment 1: As shown in FIGS. 1-10, an applicator includes brush handle 10 and at least two branches. The inner walls of the at least two branches enclose cavity 22. Each of the branches includes at least two brush strips 20. First ends of the brush strips 20 are fixedly connected to the brush handle 10. Second ends of the brush strips 20 are free ends. Two adjacent brush strips 20 in each of the branches are fixedly connected through connecting bridge 23. Protrusions 21 are respectively arranged on the brush strips 20. The connecting bridge 23 is close to the second ends of the brush strips 20. The applicator may be a mascara applicator or an eyebrow cream applicator. The protrusions 21 are used for cosmetic dipping and makeup operation. The connecting bridge 23 is close to the second ends of the brush strips, which refers to that distances from any point on the connecting bridge to the first ends are greater than distances of this point to the second ends. In the present application, an end portion of the brush handle 10 is connected to two or more branches. The inner walls of the branches enclose cavity 22 for placing a cosmetic. Each of the branches includes two or more brush strips 20 that are independent of each other. The cavity 22 is opened through free ends of the brush strips and gaps between the brush strips. When the applicator is pulled out of a cosmetic bottle, not only the protrusions 21 carry the cosmetic, but the cavity 22 also stores the cosmetic more. During makeup, the cosmetic in the cavity is added to the protrusions 21 through the free ends of the brush strips and the gaps between the brush strips. Therefore, the present application greatly improves a cosmetic carrying capacity of the applicator, makes a user dip the cosmetic from the cosmetic bottle less frequently, and achieves convenience in use and a higher makeup efficiency. The multiple brush strips 20 are independent of each other. Only certain ends of the brush strips are connected to the brush handle 10, while the remaining parts of the brush strips are free. The brush strips are flexible in transverse, longitudinal and circumferential directions, for ease of flexible makeup. Furthermore, to achieve a higher strength of the brush strips, the brush strips in each branch are fixedly connected through the connecting bridge, and the connecting bridge is biased to the free ends of the brush strips. Therefore, while ensuring the strength of the brush strips, the present application achieves a certain flexibility of the brush strips to complete the makeup smoothly.
As shown in FIGS. 2-6, the second ends of the brush strips 20 extend straight along a central axis of the brush handle 10 toward a direction away from the brush handle 10. The straight extension refers to that the brush strips 20 do not extend spirally but extend along a same circumferential direction. In the applicator, the vicinities of the second ends of the brush strips 20 are fixedly connected through the connecting bridge 23, so as to increase the strength of the brush strips. Hence, the straight extension of the brush strips 20 can meet the strength requirement of the applicator. The straight extending brush strips facilitate molding and demolding of the product.
As shown in FIG. 9, each of the brush strips 20 includes an outer surface and an inner surface that are opposite to each other. The protrusions 21 are arranged on the outer surface. The inner surfaces of the brush strips 20 enclose the cavity 22, namely the inner walls of the branches enclose the cavity 22. The inner surfaces of all brush strips 20 are located at a same side of a cylindrical space or a polyhedral space. An upper bottom surface, a lower bottom surface and any transverse section parallel to the upper bottom surface in the polyhedral space are regular polygons of a same structure. In other words, the upper bottom surface, the lower bottom surface and the transverse section are regular polygons of a same shape and a same size. When the inner surface of each brush strip 20 is a regular arc structure, the inner surfaces of all brush strips enclose a side of a cylinder, namely the cavity forms the cylinder. Certainly, the inner surface of the brush strip may also be a flat surface. The inner surfaces of all brush strips form a side of a polyhedron, namely the cavity forms the regular polyhedron. The cavity of the regular cylinder or polyhedron facilitates demolding of the applicator in production, and is favorable for large-scale industrial production.
As shown in FIG. 1 and FIG. 2, a longitudinal section of the outer surface of the brush strip 20 is a wave-shaped structure. Optionally, the longitudinal section of the outer surface of the brush strip 20 is a single-peak structure, a dual-peak structure or a multi-peak structure. The peak structure is a leading peak, a tailing peak or a symmetrical peak. When the first ends of the brush strips 20 move away from the end portion of the brush handle 10 to the free ends, the brush strips 20 spread gradually from the central axis of the applicator, and then get close gradually in the vicinities of the free ends, which is favorable for the makeup operation. Optionally, the outer surface of the brush strip 20 forms a single-wave structure, namely the single-peak structure. The highest point of the peak may be close to the first end of the brush strip, and may also be close to the second end of the brush strip, or is located in a very center of the brush strip. Optionally, the outer surface of the brush strip 20 forms a dual-wave structure (the dual-peak structure) or a multi-wave structure (the multi-peak structure).
As shown in FIG. 1, the connecting bridge 23 is close to the free ends of the brush strips 20. Optionally, a distance from a junction P between the connecting bridge 23 and the brush strip 20 to the first end is L1, a distance from the junction P to the second end is L2, and L2 is less than or equal to L1. The junction P between the connecting bridge 23 and the brush strip 20 refers to a midpoint of the connecting bridge 23 along an axial direction of the brush strip 20. Optionally, L2 is less than 0.5 times L1.
Two adjacent brush strips 20 in each branch are connected through two or more parallel connecting bridges 23. In actual design, positions and quantities of the connecting bridges are determined according to the quantities and shapes of the brush strips 20, so as to balance a degree of freedom (DOF) and a strength of the brush strips.
One row of the protrusions 21 is arranged on the brush strip 20. The protrusion 21 includes a root and a head. The root of the protrusion 21 is connected to the outer surface of the brush strip 20. The head of the protrusion 21 extends outward along a radial direction of the brush strip 20. The head of the protrusion 21 serves as a free end. The protrusion 21 is a truncated cone shaped structure. A diameter of the root is greater than a diameter of the head. With one row of the protrusions on the brush strip 20, the width of the brush strip can be as small as possible. As a result, more brush strips are provided on the brush handle 10, and the DOF of the brush strips can be improved. This is a preferred embodiment of the present application. Certainly, two or more rows of the protrusions 21 may also be arranged on the brush strip.
As shown in FIG. 1, FIGS. 5-6 and FIG. 10, the applicator is provided with three branches. Each of the branches includes two brush strips 20. The two brush strips 20 in each of the branches are connected by one connecting bridge 23. This is a preferred embodiment of the applicator. Certainly, there may also be two branches, four branches and so on according to an actual condition. Each of the branches includes three or more brush strips 20.
Optionally, the outer surface of the brush strip 20 and the inner surface of the brush strip 20 have a same shape and are parallel to each other, namely the brush strip 20 is of a thin sheet shape with a same thickness. Therefore, the shape of the cavity 22 formed by the inner surface of the brush strip 20 changes with the structure of the brush strip 20. Embodiment 2: As shown in FIGS. 11-16, the brush strip 20 is a wave-shaped structure overall. With the first end as a start point and the second end as an end point, the wave-shaped structure is shaped as a leading peak. All of the brush strips 20 spread in a petaloid manner around the central axis of the applicator. The cavity 22 in the brush strips 20 is a rugby-shaped structure.
Embodiment 3: As shown in FIGS. 17-22, the brush strip 20 is a wave-shaped structure overall. The wave-shaped structure is shaped as a symmetrical peak. All of the brush strips 20 spread in a petaloid manner around the central axis of the applicator. The cavity 22 in the brush strips 20 is a rugby-shaped structure. Embodiment 4: As shown in FIGS. 23-28, the structure of the brush strip in the embodiment is very similar to that of the brush strip in Embodiment 2, except that the brush strip 20 in the embodiment is gentler. Certainly, the brush strip 20 may also be designed as the dual-peak structure, the multi-peak structure or other wave-shaped structure.
It should be noted that those of ordinary skill in the art can further make variations and improvements without departing from the conception of the present application. These variations and improvements all fall within the protection scope of the present application. Therefore, the protection scope of the present application should be subject to the protection scope defined by the claims.
