Description

The present invention relates to an applicator for applying liquid cosmetics to keratinous substances, and in particular to an applicator for applying liquid cosmetics to eyelashes. In addition, the invention relates to kits containing such applicators.

Some applicators, including brushes having a core formed by two metal arms that hold fibers intertwined, are well known as applicators for applying liquid cosmetics to keratin materials.

In addition, applicators containing helical coils are also well known. Such applicators are disclosed in the following references.

U.S. Patent Application Publication No. 2018/0344009 is an applicator for applying mascara to eyelashes, comprising a central axis, a single coil spring helically arranged around the central axis, and a single and a securing member for securing to the one coil spring.

However, the mascara applicator described in US Patent Application Publication No. 2018/0344009 must include additional components, such as securing members, to secure the central shaft to the single coil spring. Additionally, the mascara applicator described in US Patent Application Publication No. 2018/0344009 has a complex shape that includes a central axis and a single coil spring helically arranged around the central axis. Therefore, this mascara applicator cannot be manufactured using existing manufacturing equipment capable of manufacturing typical mascara applicators with fibers.

The mascara applicator described in US Patent Application Publication No. 2018/0344009 has a single coil spring helically arranged around a central axis. Therefore, there is no gap between the central shaft and the coils of the spring and/or between the coils of the spring. In this case cosmetics, especially liquid cosmetics, cannot be sufficiently retained by this mascara applicator. Therefore, a sufficient amount of liquid cosmetic may not be applied to the eyelashes.

Even if gaps exist between the central shaft and the coils of the spring and/or between the coils of the spring, the gaps are too wide to adequately retain the cosmetic, especially the liquid cosmetic. Cosmetics can therefore be inadvertently spilled during application. Therefore, this mascara applicator cannot apply a sufficient amount of cosmetic product to the eyelashes.

WO2010/092551 discloses an applicator for applying cosmetics to keratinous materials, the applicator comprising a single coil spring with a helical structure.

The applicator of WO2010/092551 has one coil spring with a helical structure, so there are no gaps between the coil springs. In this case, the applicator cannot adequately hold cosmetics, especially liquid cosmetics. Therefore, the applicator cannot apply a sufficient amount of cosmetic product to the keratin material.

Even if gaps exist between the coil springs, the gaps between the coil springs are too wide to adequately retain the cosmetic, especially the liquid cosmetic. Cosmetics can therefore be inadvertently spilled during application. Therefore, this applicator cannot apply a sufficient amount of cosmetic product to the keratin material.

Furthermore, the applicator of WO2010/092551 may cause injury to the user or consumer due to the tip of the coil spring.

US Pat. No. 8,079,373 discloses a mascara applicator comprising a single spring coil having a helical structure and a member made of plastic material for covering the tip of the spring coil.

The mascara applicator of US Pat. No. 8,079,373 includes additional components such as members made of plastic material. Therefore, this mascara applicator cannot be manufactured using existing manufacturing equipment capable of manufacturing typical mascara applicators with fibers.

In addition, this mascara applicator has a single spring coil with a helical structure, so the gap between the spring coils is small. In this case, this mascara applicator cannot hold cosmetics, especially liquid cosmetics, well. Therefore, it is not possible to apply a sufficient amount of cosmetic product to the keratin material.

Furthermore, if the gap between the coils of the spring is too wide, it will not be able to hold the cosmetic product, especially liquid cosmetic product, and thus the cosmetic product may inadvertently spill during application. Therefore, this mascara applicator cannot apply a sufficient amount of cosmetic to the keratin material.

U.S. Pat. No. 3,998,235 is a mascara applicator that includes a central rod, a single spring coil helically disposed about the central rod, and a cap member for connecting the central rod to the spring coil. discloses a mascara applicator in which the cap member is positioned at the distal end of the central rod.

This mascara applicator must include additional components, such as a cap member, to connect the central rod to the coil of the spring. Additionally, the mascara applicator described in US Pat. No. 3,998,235 has a complex shape that includes a central rod and a single coil of spring helically arranged around the central rod. Therefore, this mascara applicator cannot be manufactured using existing manufacturing equipment capable of manufacturing typical mascara applicators with fibers.

Additionally, the mascara applicator of US Pat. No. 3,998,235 has a single coil of spring helically arranged around a central rod. Therefore, there are no gaps between the central rod and the coil springs and/or between the coil springs. In this case cosmetics, especially liquid cosmetics, cannot be sufficiently retained by this mascara applicator. Sufficient amounts of liquid cosmetics cannot therefore be applied to keratinous substances.

Even if a gap exists between the central rod and the coil spring and/or between the coil spring, the gap is too wide to adequately retain the cosmetic, especially the liquid cosmetic. Cosmetics can therefore be inadvertently spilled during application. Therefore, this mascara applicator cannot apply a sufficient amount of cosmetic to the keratin material.

US Pat. No. 4,744,377 discloses an applicator for applying mascara to eyelashes that includes a helical structure.

The mascara applicator of US Pat. No. 4,744,377 has no gaps in the helical structure. In this case, this mascara applicator cannot hold cosmetics, especially liquid cosmetics, well. Therefore, this mascara applicator cannot apply a sufficient amount of mascara cosmetic to the eyelashes.

Even when gaps are formed in the helical structure, the gaps are too wide to adequately retain cosmetics, especially liquid cosmetics. Cosmetics can therefore be inadvertently spilled during application. Therefore, this mascara applicator cannot apply a sufficient amount of mascara cosmetic to the eyelashes.

Furthermore, US Pat. No. 4,744,377 does not disclose how to make this mascara applicator.

Stem 60 has a proximal end 62 and a distal end 64 . A distal end 64 of stem 60 is provided with an applicator head 50 and a proximal end 62 of stem 60 is provided with gripping portion 40 .

The shape and material of stem 60 are not limited as long as stem 60 can support applicator head 50 . The shape of stem 60 can be, for example, cylindrical, pyramidal, conical, pyramidal, barrel-shaped, teardrop-shaped, elliptical, or spherical. In addition, the material of the stem 60 can be transparent glass, frosted glass, translucent glass, or colored glass (soda lime glass, crystal glass, etc.), transparent synthetic resin, frosted synthetic resin, translucent synthetic resin, or colored synthetic resin ( PE, PP, PET, etc.), and metals (aluminum, etc.).

As seen particularly in FIG. 1, the container 20 includes a body 22 having a threaded neck 24 thereon, into which a grip 40 is threaded to hermetically close the container 20 . can be done. Alternatively, applicator 30 may be attached to container 20 in some other manner.

As shown, the neck 24 can receive a wiping member 26 mounted therein, for example. The wiping member 26 has a lip 28 defining a wiping hole of diameter matching the diameter of the stem 60 .

Applicator head 50 may be attached in a conventional manner at distal end 64 of stem 60 .

[Multiple helix structure]
As shown in FIGS. 2 and 3 of the present application, the applicator head 50 has a multi-helical structure 100. As shown in FIG.

The multiple helix structure 100 is a structure in which a plurality of wires 102 are helically twisted and combined parallel to each other. The multi-helical structure 100 extends along the longitudinal axis X, and the wire 102 making up the multi-helical structure 100 is wrapped around the longitudinal axis X.

The diameter D of the multi-helical structure 100, and in particular the diameter D _Max of the largest diameter portion within the multi-helical structure 100, is formed to be equal to or smaller than the diameter of the stem 60. FIG. Thereby, when the applicator 30 is removed from the container 20, excess cosmetic product P adhering to the applicator head 50 and/or stem 60 is wiped off by the wiping hole defined by the lip 28, leaving the applicator, In particular, the applicator head 50 can easily pass through the wiping holes.

Multi-helical structure 100 has a distal end 106 , a proximal end 104 opposite distal end 106 , and a body portion 108 between distal end 106 and proximal end 104 . The proximal end 104 of the multiple helix structure 100 is attached to the stem 60 .

The diameter D of the body portion 108 within the multiple helix structure 100 is the same along the entire longitudinal length. However, the diameter D of the body portion 108 within the multi-helical structure 100 may vary along its length, e.g., the diameter D of the body portion 108 within the multi-helical structure 100 is It may gradually decrease or gradually increase to both sides in the longitudinal direction. Additionally, the diameter D of the body portion 108 within the multi-helical structure 100 may gradually decrease or increase along the length of the applicator head 50 from the distal end to the proximal end.

At the proximal end 104 of the multi-helical structure 100, the wires 102 are tightly stranded so there are no gaps between the wires 102. FIG. In other words, proximal end 104 of multi-helical structure 100 has a configuration in which wires 102 are tightly interwoven. Therefore, the diameter of proximal end 104 within multi-helical structure 100 is smaller than the diameter D of body 108 within multi-helical structure 100 .

Additionally, the longitudinal length of proximal end 104 of multi-helical structure 100 can be long enough to support applicator head 50 .

FIG. 4 of the present application is an enlarged view of distal end 106 of multi-helical structure 100. FIG. As shown in FIG. 4 of the present application, distal end 106 of multi-helical structure 100 has tip 110 extending along longitudinal axis X of applicator head 50 . Additionally, distal end 106 of multi-helical structure 100 tapers to tip 110 . In other words, distal end 106 of multi-helical structure 100 tapers in diameter toward tip 110 .

Additionally, this tip 110 is a folded tip 102 formed by folding at least one wire 102 . The bent tip is formed to have a rounded shape. In other words, the bending tip is formed of a wire that bends according to a given radius of curvature.

2-4 of the present application, the multiple helix structure 100 may be formed by folding at least one wire 102 in two and twisting the two wires 102 together. At least one wire 102 is made of plastically deformable material, specifically the material of wire 102 is metal, preferably stainless steel, more preferably ALSL316L.

Gaps 112 are formed between wires 102 in multi-helical structure 100 . These gaps 112 can act as bulk reservoirs to hold liquid cosmetics P having a predetermined viscosity. In other words, the liquid cosmetic P having a predetermined viscosity is retained in these gaps 112 between the wires 102 by capillary action of the liquid cosmetic P.

The multiple helix structure 100 may be in the shape of a cylinder having a longitudinal length L and a diameter D. FIG.

The length L of the multiple helix structure 100 is in the range of about 20mm to about 35mm, preferably about 25mm to about 30mm, and more preferably about 27mm. The diameter D of the multi-helical structure 100 is in the range of about 1.5mm to about 3mm, preferably in the range of about 1.75mm to about 2.6mm, and more preferably about 2.15mm.

Additionally, the multiple helix structure 100 has a pitch P of about 1.5 mm to about 5 mm, preferably about 3 mm. Furthermore, the number of pitches P of this multiple helix structure can be between 5 and 15, preferably 10.

Additionally, the diameter D _W of wire 102 is about 0.3 mm to about 1 mm, preferably about 0.5 mm to about 0.8 mm, and more preferably about 0.65 mm.

As shown in FIG. 3 of the present application, at least one wire 102 has a predetermined angle α with respect to longitudinal axis X of applicator head 50 . In other words, the predetermined angle α is arranged between the longitudinal axis X and the at least one wire 102 . This angle α may be between 30 and 50 degrees, preferably less than 45 degrees.

[Cosmetics]
An applicator 30 having a multiple helical structure 100 is suitable for applying a liquid cosmetic product P having a specific viscosity to keratin substances. In other words, a liquid cosmetic product P with a certain viscosity can be held by the applicator head 50, in particular by at least one wire 102 by using capillary action.

Cosmetic P has a viscosity of 30 UD (deviation units) to 50 UD, preferably 35 UD to 40 UD, measured at 25° C. using a RHEOMAT 180 viscometer equipped with a spindle M2 rotating at 200 rpm.

As explained above, the viscosity of the compositions according to the invention is measured at 25° C. using a PRORHEO R180 viscometer from the company PRORHEO equipped with a spindle M2 rotating at 200 rpm.

In addition, the viscosity of cosmetics P can be measured as follows. Viscosity is generally a kinetic body suitable for the viscosity of the product (a kinetic body chosen so that the measured value is always between 30UD and 50UD, preferably between 35UD and 40UD, or in deviation units) was measured at 25° C. using a RHEOMAT RM 180 viscometer equipped with at a shear rate of 200 s' after turning.

Cosmetics have a contact angle β. The contact angle β is between about 20 and about 70 degrees, preferably between about 30 and about 60 degrees. The contact angle β can be measured as follows. A drop of cosmetic, especially liquid cosmetic, is placed on the surface of a plate, such as a glass plate, using a syringe. Approximately 20 seconds after instillation, contact angle β measurements are performed using images captured by a PC using a camera. The WINGOUTTE software digitizes the drop contours by image processing. The software then uses interpolation to determine the contact angle β. The WINGOUTTE software uses polynomial or arc-of-circle interpolation methods to determine the contact angle β. In some cases, the power system allows the advancing and receding angles of the drop to be measured, and the syringe needle is then held in the drop.

[Production method]
The applicator head 50 of the present invention can be manufactured using existing manufacturing equipment.

Existing manufacturing equipment is for manufacturing conventional applicator heads, i.e., applicator heads that sandwich the fibers between the metal wires by twisting the metal wires with the fibers.

A method for manufacturing an applicator head 50 having a multiple helix structure 100 of the present invention comprises:
- providing a plurality of wires 102;
- fixing the wire 102 at one end thereof by using welding or other known fixing methods;
- fixing the free end of the fixed wire 102 to existing manufacturing equipment;
- twisting the wire 102 from the free end to the fixed end;
- After the twisting step, these wires 102 are twisted from the fixed end (corresponding to distal end 110) to the vicinity of the free end (corresponding to proximal end 104) to form multi-helical structure 100. and untwisting or untwisting the wires 102 that have been twisted.

The steps of preparing the plurality of wires 102 are described in detail below.
These wires 102 may be multiple straight wires 102 and the lengths of these wires 102 may be the same or different from each other.

Securing the wires 102 at one end thereof may be performed by the following method.
These wires 102 can be connected or fixed to each other at their one ends by using known fixing methods, in particular by using a welding process. Since the fixed ends of wires 102 correspond to tips 110, these fixed ends of wires 102 must have a rounded shape.
Additionally, the single straight wire 102 may be bent into a U-shape by using a jig or the like, or folded in two to form a bend at or near the center of the wire 102. may be One ends of the wires 102 to each other can be connected or fixed to the bends of the wires 102 by using known fixing methods, in particular by using a welding process. These wires 102 may have free ends extending along the same direction, and the wire sections may extend parallel to each other. Since the bend of the wire 102 corresponds to the tip 110, the bend must be bent so that the tip 110 has a rounded shape.
Additionally, each of the wires 102 may be bent in a U-shape or folded in two to form a fold at the center or midsection of each wire 102 . The folds can then be secured together by welding or using other known securing methods.

The step of twisting wire 102 from the free end to the fixed end is described in detail below.
By using existing manufacturing equipment, the free ends of the wires 102 may be fixed and the fixed ends of the wires 102 may be twisted around the length so that the wires 102 are tightly and/or tightly stranded. is rotated in one direction. In other words, these wires 102 are tightly and/or tightly stranded such that there are no gaps between the wires 102 .

The step of untwisting or untwisting the stranded wire 102 from the fixed end (corresponding to tip 110) to near the free end is described in detail below.
The fixed ends or bends of the twisted wires 102 are turned about the longitudinal axis in a direction opposite to the direction of rotation in which the wires 102 are twisted. This causes the stranded metal wires 102 to be untwisted or untwisted from the folds by a predetermined length. This therefore results in the formation of a multi-helical structure 100 having a longitudinal length L from tip 110 . Of course, at the proximal end of multi-helical structure 100, wires 102 remain tightly and/or tightly stranded.
The untwisting or untwisting steps described above may be performed continuously with the twisting step by using existing manufacturing equipment as described above. That is, the manufacturing equipment can turn the fixed ends or folds in one direction to twist the wires 102 and then turn the fixed ends or folds in the opposite direction without replacing anything.

Of course, the applicator head 50 including the multi-helical structure 100 of the present invention may be formed in other ways known to those skilled in the art.

The bent metal wire 202 has both ends extending along the same direction and the two wire sections extend parallel to each other.
Since the bend of the metal wire 202 corresponds to the tip 110, the bend must be bent so that the tip 110 has a rounded shape.

In addition, the steps of twisting the metal wire 202 from both ends of the metal wire 202 to the bends are described in detail below.
By using existing manufacturing equipment, both ends of the metal wire 202 are fixed and the folds are unidirectionally turned about the longitudinal axis.
Metal wires 202 can thereby be twisted together.
By twisting the metal wires 202, the two metal wires 202 are twisted tightly or closely together. In other words, the two metal wires 202 are tightly or intimately stranded such that there is no gap between the metal wires 202 .

The steps of untwisting or untwisting the stranded metal wire 202 from the bend to near the ends to form the double helix structure 200 are described in detail below.
The folds of the twisted metal wires 202 are turned about the longitudinal axis in a direction opposite to the direction of rotation in which the metal wires 202 are twisted. This causes the stranded metal wires 202 to be untwisted or untwisted from the fold for a predetermined length. This therefore results in the formation of a double helix structure 200 having a longitudinal length L from the tip 110 corresponding to the fold. Of course, at the proximal end of double helix structure 200, metal wire 202 remains tightly and/or tightly stranded.
The untwisting or untwisting steps described above may be performed continuously with the twisting step by using existing manufacturing equipment as described above. That is, the manufacturing equipment can turn the folds in one direction to twist the metal wire 202 and then turn the folds in the opposite direction without replacing anything.
