Description

Technical Field

[0001] The present invention relates to a beauty patch and a skin beauty instrument comprising the same. Background Art

[0002] As people pay more attention to beauty, the demand not only for cosmetics but also for beauty patches and skin beauty devices that can improve skin condition is increasing.

[0003] Reflecting this need, conventional technologies have proposed facial masks and beauty patches equipped with LEDs that emit light within a specific wavelength range that can improve skin. Furthermore, conventional beauty patches and facial masks have also proposed using flexible substrates that can bend to conform to the shape of the body.

[0004] However, existing beauty devices using flexible substrates have the property of deforming to conform to the body's shape and then returning to their original shape, resulting in a problem of not being able to completely adhere to the body. This creates a space between the device and the body, preventing the device's effects (e.g., LED wavelength) from being effectively transmitted to the skin.

[0063] Hereinafter, specific embodiments of the present invention will be described in detail with reference to the accompanying drawings.

[0064] Furthermore, when describing the present invention, if it is determined that a detailed description of a related known configuration or function may obscure the gist of the present invention, the detailed description will be omitted.

[0065] Figure 1 is a perspective view showing a cosmetic patch 10 according to an embodiment of the present invention, Figure 2 The schematic shows the Figure 1 The cross section of the cosmetic patch 10 taken along line A'-A' is as follows: Figure 3 The schematic diagram shows the shape of the cosmetic patch after the external force applied to it is released. Figure 2 Cross-section of the cosmetic patch 10 .

[0066] refer to Figures 1 to 3 According to one embodiment of the present invention, a cosmetic patch 10 may include: a flexible substrate layer 100 that is deformable by external forces and has a restoring force; and a metal layer 300 formed on at least one of the front and back surfaces of the flexible substrate layer 100, capable of maintaining the shape of the flexible substrate layer 100 when deformed by external forces. One or more light-emitting elements 110 may be provided on the front surface of the flexible substrate layer 100.

[0067] In addition, a crack prevention layer 200 may be selectively provided between the flexible substrate layer 100 and the metal layer 300 to prevent cracks in the metal layer 300. In addition, the cosmetic patch 10 may include a surface layer 400 that forms an appearance.

[0068] In this embodiment, Figure 1 The front of the cosmetic patch 10 is defined as the +z direction and the back direction as the -z direction. The front of the cosmetic patch 10 can be understood as the direction in which light from the light-emitting element 110 illuminates the user's skin. Furthermore, after the front of the cosmetic patch 10 is positioned facing the user's skin, the cosmetic patch 10 can be applied to the skin.

[0069] The metal layer 300 may be disposed on at least one of the front and rear surfaces of the flexible substrate layer 100 . However, in this embodiment, the metal layer 300 is disposed on the front surface of the flexible substrate layer 100 for description.

[0070] The cosmetic patch 10 of this embodiment can deform to conform to the shape of the user's body (e.g., face, neck, arms, legs, etc.) and can maintain this deformed shape. For example, the cosmetic patch 10 can be deformed by external force applied by the user to conform to the curve of the user's face (or neck, arms, legs). When the user then releases the external force applied to the cosmetic patch 10, the cosmetic patch 10 can maintain its shape conforming to the facial curve. Therefore, when the cosmetic patch 10 is attached to the body, the space between the cosmetic patch 10 and the body can be eliminated or minimized. In this case, the cosmetic functions provided by the cosmetic patch 10 (e.g., LED light illumination, microcurrent, etc.) can be effectively transmitted to the user's body.

[0071] The flexible substrate layer 100 can be elastically deformed by an external force and can return to its original shape when the applied external force is released. For example, the flexible substrate layer can be a flexible substrate.

[0072] One or more light-emitting elements 110 may be provided on the front of the flexible substrate layer 100. The light-emitting element 110 may be an LED element, and a plurality of light-emitting elements 110 may be provided. The light-emitting element 110 may be mounted on the flexible substrate layer 100 using surface mount technology (SMT). In this case, the light-emitting element 110 and the flexible substrate layer 100 may be integrally formed.

[0073] Furthermore, light emitting elements 110 having different characteristics are arranged in multiple regions of the flexible substrate layer 100 , so that light having different wavelengths can be irradiated onto the user's skin. This will be described in detail later.

[0074] The thickness of the flexible substrate layer 100 may be 0.1 mm to 0.3 mm.

[0075] The flexible substrate layer 100 may be provided in the form of a coating or a thin film. In this case, the thickness of the flexible substrate layer 100 may be 0.005 mm to 0.1 mm.

[0076] Furthermore, the metal layer 300 may have different properties from the flexible substrate layer 100. Specifically, the flexible substrate layer 100 may have a property of returning to its original shape after being deformed by an external force, whereas the metal layer 300 may have a property of maintaining its deformed state after being deformed by an external force.

[0077] The metal layer 300 and the flexible substrate layer 100 can adhere to each other and deform into the same shape. Furthermore, the metal layer 300 provides a force (supporting force) greater than the force required to restore the flexible substrate layer 100 to its original shape, thereby supporting the flexible substrate layer 100. In other words, after the cosmetic patch 10 is deformed by an external force, the metal layer 300 maintains the deformed shape.

[0078] Assumptions Figure 2 The cosmetic patch 10 shown in FIG is a state before external force is applied. Figure 3 The cosmetic patch 10 shown in FIG. 1 can be understood as a state in which, after being deformed by an external force, the deformed shape is maintained when the external force is released.

[0079] The metal layer 300 that can maintain its deformed shape after being deformed by an external force can be made of one of aluminum, magnesium, copper, and stainless steel (STS304). However, the present invention is not limited thereto, and the metal layer 300 can include all materials that can be deformed by an external force and can maintain its deformed shape when the external force is removed. The external force can be understood as a physical force applied by the user's operation. In addition, in this embodiment, the case where the metal layer 300 is in the shape of a plate (plate material) is used for illustration, but the present invention is not limited thereto, and the metal layer 300 can be in the shape of a tube (a shape with a hollow interior).

[0080] The thickness of the metal layer 300 may be set in proportion to the thickness of the flexible substrate layer 100 .

[0081] When the thickness of the flexible substrate layer 100 increases, the force for the flexible substrate layer 100 to restore its original shape increases. Therefore, the thickness of the metal layer 300 may also increase in proportion to this.

[0082] The thickness ratio of the flexible substrate layer 100 to the metal layer 300 may be 1-2: 1. For example, the thickness ratio of the flexible substrate layer 100 to the metal layer 300 may be 1:1. When the thickness of the flexible substrate layer 100 is 0.2 mm, the thickness of the metal layer 300 may also be 0.2 mm.

[0083] The metal layer 300 may be provided in a plate shape capable of covering one side of the flexible substrate layer 100. In this case, when the metal layer 300 is provided on the front surface of the flexible substrate layer 100, the metal layer 300 may cover the entire front surface of the flexible substrate layer 100 except for the region where the light emitting element 110 is disposed.

[0084] Alternatively, the metal layer 300 may be provided in a plate shape that covers at least 90% of the front surface of the flexible substrate layer 100. In this case, the metal layer 300 can support the flexible substrate layer 100 over the entire surface, thereby stably supporting the substrate layer 100. Furthermore, the metal layer 300 can be thinned to reduce its thickness.

[0085] When the metal layer 300 is provided in a plate shape, it can uniformly support the entire front surface of the flexible substrate layer 100 (excluding the portion where the light emitting element 110 is provided) to be restored to its original shape, thereby effectively maintaining the shape of the deformed flexible substrate layer 100.

[0086] However, the metal layer 300 of this embodiment is not limited to a plate shape. For example, the metal layer can be provided in the form of lines or strips surrounding the outer periphery of the flexible substrate layer 100, or in a lattice pattern such as a Go board pattern. The above configurations can also be provided in a composite or mixed form. This will be described in more detail later. The crack prevention layer 200 can be selectively disposed between the substrate layer 100 and the metal layer 300.

[0087] When deformation is repeatedly applied to the metal layer 300 due to an external force, cracks may be generated in the metal layer 300 . However, when the crack prevention layer 200 is provided, the metal layer 300 can be prevented from cracking.

[0088] In addition, the crack prevention layer 200 can improve the adhesion between the flexible substrate layer 100 and the metal layer 300. For example, the crack prevention layer 200 can be a foam tape, a PET-based tape, an ultrasonic tape, or the like.

[0089] The surface layer 400 can be attached to the user's skin and can be provided by a material having elasticity, for example, a silicon material.

[0090] The surface layer 400 may form the appearance of the cosmetic patch 10 and may surround at least a portion of the flexible substrate layer 100 , the anti-crack layer 200 , and the metal layer 300 .

[0091] The internal structure of the cosmetic patch 10 (flexible substrate layer 100, anti-crack layer 200, metal layer 300, etc.) can be covered by the surface layer 400, so the user can only see the surface layer 400 with the naked eye. The surface layer 400 can be understood as covering the back of the flexible substrate layer 100, the front of the metal layer 300, and the side surfaces of the flexible substrate layer 100, anti-crack layer 200, and metal layer 300.

[0092] In addition, the surface layer 400 may be provided to be transparent so as to allow the light emitted by the light emitting element 110 to pass therethrough and be transferred to the skin.

[0093] Specifically, the surface layer 400 may include: a front layer 402 located in front of the light-emitting element 110 and directly covering the light-emitting element 110; a rear layer 404 located on the opposite side to the front layer 402; and a side layer connecting the front layer 402 and the rear layer 404.

[0094] The front layer 402 may be provided by a transparent material through which LED light can pass, so that the light emitted by the light emitting element 110 is transmitted to the user's skin.

[0095] Alternatively, the front layer 402 may directly contact the user's skin. In this case, the front layer 402 can be adhered to the user's skin without requiring any other substance such as an adhesive.

[0096] The back layer 404 and the side layer 406 can be made of opaque or translucent materials to prevent the light from the light emitting element 110 from passing through. In this case, the light emitted by the light emitting element 110 can be prevented from entering the user's eyes when the user wears the cosmetic patch 10.

[0097] In addition, a shielding layer (not shown) capable of shielding light emitted by the light-emitting element 110 may be provided on at least one of the rear layer 404 and the side layer 406. For example, the shielding layer may be disposed between the flexible substrate layer 100 and the rear layer 404 to prevent light emitted by the light-emitting element 110 from leaking to the rear.

[0098] Alternatively, the entire surface layer 400 may be formed of a transparent material, and a shielding layer may be disposed between the flexible substrate layer 100 and the rear layer 404. In this case, light leakage to the rear of the cosmetic patch 10 is prevented, and by providing the surface layer 400 with the same material, the manufacturing process can be expected to be more convenient.

[0099] In addition, a power connection portion 23 may be provided on one side of the beauty patch 10 , and the power connection portion 23 may provide power from the beauty instrument body to the beauty patch 10 , which will be described in detail later. Figure 4 It is shown schematically Figure 1 Schematic diagram of the front of the cosmetic patch 10.

[0100] refer to Figure 4 The shape of the cosmetic patch 10 and the arrangement of the light emitting elements 110 are described. Figure 4 BB' can be understood as a virtual line parallel to the x-axis.

[0101] refer to Figure 4 The cosmetic patch 10 can have a size and shape that can be attached to a part of the user's face. For example, the cosmetic patch 10 can be in the shape of a triangular plate, and a concave recessed portion 122 can be provided on one side of the cosmetic patch 10. However, the shape of the cosmetic patch 10 is not limited to a triangular shape, and can also include a recessed portion in a quadrilateral or circular shape. The recessed portion 122 can be understood as a portion that is recessed with the virtual straight line BB' as a reference. Specifically, the recessed portion 122 can be understood as a portion formed by connecting a first surface 122a that contacts the virtual straight line BB' at a fulcrum and a second surface 122b that contacts the virtual straight line BB' at another fulcrum. The angle between the first surface 122a and the second surface 122b can be an obtuse angle. In this case, the recessed portion 122 can also be a shape that is recessed in a curved shape, or a shape that is recessed in an angular form.

[0102] When the cosmetic patch 10 is applied to the user's face, the recessed portion 122 can be positioned below the eyes or on the nasolabial folds around the mouth and nose. Providing the recessed portion 122 in this manner allows the cosmetic patch 10 to be easily applied to the face without interference from the eyes, nose, mouth, etc. This minimizes or eliminates the gap between the cosmetic patch 10 and the face, effectively improving wrinkles around the eyes and nasolabial folds.

[0103] The front of the cosmetic patch 10 (including the front of the flexible substrate layer 100) can be divided into multiple virtual regions C, D, E, and F. The light-emitting elements arranged in these regions C, D, E, and F can emit light of different wavelengths. For example, the flexible substrate layer 100 can be divided into a virtual first region C, a second region D, a third region E, and a fourth region F.

[0104] A first light-emitting element 112 may be disposed in the first region C, emitting light in the red wavelength band. A second light-emitting element 114 may be disposed in the second region D, emitting light in the yellow wavelength band. A third light-emitting element 116 may be disposed in the third region E, emitting light in the blue wavelength band. A fourth light-emitting element 118 may be disposed in the fourth region F, emitting light in the NIR (near infrared) wavelength band.

[0105] Figure 4 The first region C, the second region D, the third region E, and the fourth region F are shown as being arranged in this order from the recess 122 toward the bottom (-y axis direction), but the present invention is not limited thereto. For example, virtual regions may be set from the outer edge of the flexible substrate layer 100 toward the inner side.

[0106] Figure 5 is a cross-sectional view of a cosmetic patch 10 ′ according to another embodiment of the present invention.

[0107] Will Figure 5 and Figure 2 The embodiment shown in FIG1 differs mainly in that the crack prevention layer 200 ′ and the metal layer 300 ′ are disposed behind the flexible substrate layer 100 ′. Therefore, the description will focus on the differences, and the description and reference numerals of the above embodiment will be used for the same parts.

[0108] refer to Figure 5 In other embodiments of the cosmetic patch 10 ′ of the present invention, an anti-crack layer 200 ′ and a metal layer 300 ′ may be disposed behind the flexible substrate layer 100 ′.

[0109] That is, the cosmetic patch 10 ′ of this embodiment may be configured in the order of the surface layer 400 ′, the flexible substrate layer 100 ′, the anti-crack layer 200 ′, and the metal layer 300 ′.

[0110] As described above, by disposing the metal layer 300 ′ behind the flexible substrate layer 100 ′, it is possible to shield the light emitted by the light emitting element 110 ′ from being released toward the rear of the cosmetic patch 10 ′.

[0111] Furthermore, by disposing the metal layer 300' behind the flexible substrate layer 100', the distance between the light emitting element 110' and the skin can be reduced, thereby effectively delivering the beauty function (light irradiation, etc.) provided by the beauty patch 10' to the skin.

[0112] In addition, the cosmetic patch 10' of the present invention may include a structure for applying microcurrent to the user's skin. In this case, when the metal layer 300' is disposed behind the flexible substrate layer 100', the microcurrent can flow through the metal layer 300'.

[0113] above Figures 1 to 4 FIG. 4 shows a case where the metal layer 300 is disposed in front of the flexible substrate layer 100. Figure 5 The metal layer 300' is shown as being disposed behind the flexible substrate layer 100'. However, the present invention is not limited thereto and the metal layer can be disposed on both the front and back of the flexible substrate layer. In this case, the metal layer 300 is disposed on both sides of the flexible substrate layer 100, thereby effectively supporting the flexible substrate layer 100.

[0114] Figure 6 is a three-dimensional diagram of a cosmetic patch 10" according to yet another embodiment of the present invention. Figure 7 Therefore Figure 6 The cross-sectional view is taken from the A"-A" line of the Figure 8 It is an enlarged cross-sectional view of the adhesive portion 500 before and after receiving an external force from the user.

[0115] Will Figures 6 to 8 The beauty patch 10" with Figure 1 When compared with the cosmetic patch 10, there is a difference in that it also includes an adhesive portion 500, so the description will be mainly based on the differences, and the description and reference numerals of the above embodiment will be used for the same parts. In addition, for the convenience of description, Figures 6 to 8 The sticking portion 500 is shown in an enlarged manner in FIG.

[0116] refer to Figures 6 to 8 According to yet another embodiment of the present invention, the cosmetic patch 10" may be stacked in the order of a surface layer 400", a metal layer 300", an anti-crack layer 200", and a flexible substrate layer 100".

[0117] At least one adhesive portion 500 may be provided on the front of the surface layer 400" of the cosmetic patch 10" of this embodiment. Specifically, at least one adhesive portion 500 may be provided on the front of the front layer 402".

[0118] When the adhesive portion 500 is provided on the front of the surface layer 400", the adhesive force between the cosmetic patch 10" and the skin can be improved.

[0119] The adhesive portion 500 may be provided in a plurality of forms and may be provided in a material and shape that can be attached to the user's skin. For example, the adhesive portion 500 may be formed in a suction cup shape.

[0120] The adhesive portion 500 has a central depression and can be circular when viewed from the front. The diameter d of the adhesive portion 500 can be 10-15 mm, and the height h of the adhesive portion 500 can be 0.5 mm-2.5 mm. Furthermore, the spacing between the adhesive portions 500 can be set so as not to affect the light emitted from the light-emitting element 110 to the skin. For example, the spacing between the adhesive portions 500 can be 1.5 mm-9 mm. However, this is not limiting, and depending on the configuration of the light-emitting element 110, the spacing between the adhesive portions 500 can also be greater than 9 mm.

[0121] The adhesive portion 500 may include a lower surface 504 integrally formed with the surface layer 400 ″ and an upper surface 502 elastically deformable on the upper side of the lower surface 504 . An adsorption space 506 may be formed between the lower surface 504 and the upper surface 502 .

[0122] The adhesive portion 500 may be integrally formed by injection molding with the surface layer 400 ″, and the adhesive portion 500 may be made of the same silicon material as the surface layer 400 ″.

[0123] In addition, the adhesive portion 500 may be made of a transparent material so that the light emitted by the light emitting element 110 can be irradiated onto the skin through the adhesive portion 500 . Figure 8 (a) is a cross section of the adhesive portion 500 before a force F is applied from the skin. Figure 8 (b) is a cross-section of the adhesive portion 500 when the cosmetic patch 10" is attached to the skin K.

[0153] According to yet another embodiment of the present invention, the metal layer 300'' of the cosmetic patch 10'' can be configured on a portion of the flexible substrate layer 100''. For example, a plurality of metal layers 300'' can be configured in a strip form between the light-emitting elements 110''. In this embodiment, the metal layer 300'' is configured as an edge 302 of the flexible substrate layer 100'' and three horizontal columns 304, 306, and 308 of the light-emitting elements 110''.

[0154] However, the present invention is not limited thereto, and the metal layer 300 ′″ may also be arranged in a horizontal and vertical lattice pattern between the light emitting elements 110 .

[0155] Figure 15 is a three-dimensional diagram of a cosmetic patch 10"" according to yet another embodiment of the present invention. Figure 16 The schematic shows the Figure 15 The cross section is taken along the D-D' line.

[0156] Will Figure 15 as well as Figure 16 and Figure 1 When compared with the embodiment shown in , the main difference is that a shape memory alloy 3000 is provided instead of the metal layer 300. Therefore, the description will be mainly based on the differences, and the description and reference numerals of the above embodiment are used for the same parts.

[0157] Figure 15 and Figure 16 The cosmetic patch 10"" can be applied to the body with a certain curvature, such as the neck and arms.

[0158] refer to Figure 15 as well as Figure 16 The cosmetic patch 10"" may include a flexible substrate layer 100"" having a light-emitting element 110"" mounted on the front thereof, and a shape-memory alloy 3000 provided at the edge of the flexible substrate layer 100"". The shape-memory alloy 3000, as a metal intended to maintain a preset shape, may be a metal having a circular or polygonal (including pentagonal, quadrilateral, triangular, etc.) cross-section.

[0159] The shape memory alloy 3000 may be disposed along the periphery of the cosmetic patch 10".

[0160] The flexible substrate layer 100"" can be supported by the shape memory alloy 3000 to maintain a certain shape. For example, when the shape memory alloy 3000 is formed to conform to a predetermined curvature (the curvature of the neck or arm), the flexible substrate layer 100"" can maintain the same shape as the shape memory alloy 3000.

[0161] exist Figure 15 as well as Figure 16 The application of the shape memory alloy 3000 in cosmetic patches for the neck and arms is described above. However, the shape memory alloy 3000 is not limited thereto. The shape memory alloy 3000 can also be applied to mask pieces having a curvature above a certain value.

[0162] The effects of the beauty patch and the beauty instrument are described below.

[0163] The cosmetic patch 10 of this embodiment can deform to conform to the shape of the user's body (e.g., face, neck, arms, legs, etc.) and maintains this deformed shape. Therefore, when the cosmetic patch 10 is applied to the body, the gap between the cosmetic patch 10 and the body can be eliminated or minimized. In this way, the cosmetic functions provided by the cosmetic patch 10 (e.g., LED light, microcurrent, etc.) can be effectively delivered to the user's body.

[0164] In addition, when the metal layer 300 of the cosmetic patch 10 is provided in a plate shape, it can uniformly support the entire front surface of the flexible substrate layer 100 (excluding the portion where the light-emitting element 110 is provided) that is to be restored to its original shape, thereby effectively maintaining the shape of the deformed flexible substrate layer 100.

[0165] In addition, the crack prevention layer 200 may be disposed between the flexible substrate layer 100 and the metal layer 300. When the metal layer 300 is repeatedly deformed by external force, cracks may be generated in the metal layer 300. However, the crack prevention layer 200 can prevent the metal layer 300 from cracking.

[0166] In addition, by providing the crack prevention layer 200 , the adhesion between the flexible substrate layer 100 and the metal layer 300 can be improved.

[0168] Furthermore, when the cosmetic patch 10 is applied to the user's face, the recessed portion 122 can be positioned below the eyes, or in the nasolabial folds around the mouth and nose. Providing the recessed portion 122 in this manner allows the cosmetic patch 10 to be easily applied to the face without interference from the eyes, nose, or mouth.

[0169] In addition, the cosmetic patch 10' according to other embodiments of the present invention can be configured in the order of a surface layer 400', a flexible substrate layer 100', a crack prevention layer 200', and a metal layer 300'. As described above, by placing the metal layer 300' behind the flexible substrate layer 100', the light emitted by the light-emitting element 110' can be shielded from being released toward the rear of the cosmetic patch 10'.

[0170] In addition, when the adhesive portion 500 is provided on the front surface of the surface layer 400, the adhesive force between the cosmetic patch 10" and the skin can be improved.

[0171] Furthermore, a groove 22 can be provided on the inner side of the main body 20 for inserting the connecting wire 21. The user can insert the connecting wire 21 into the groove 22 and wear the skin beauty device 1 on a part of the body (e.g., the head or neck). In this case, the connecting wire 21 can be fixed by the groove 22, so the user can carry out activities while wearing the skin beauty device 1 on the head or neck and attaching the beauty patch 10 to the face.
