Description

[Technical Field]

[0001] The present invention relates to a facial care tool that can be worn on the face to provide skin care for desired areas such as the cheeks, nose, and around the mouth. [Background technology]

[0002] Conventionally, face packs impregnated with moisturizing lotion, lotion, etc. have often been used to moisturize and maintain the beauty of facial skin (see, for example, Patent Document 1). Conventional face packs are made of a sheet of nonwoven fabric or the like large enough to cover almost the entire human face, with holes formed in the sheet in areas corresponding to the eyes, nose, and mouth. The sheet is impregnated with a cosmetic lotion or the like and then placed in close contact with the human face. Face packs can be purchased relatively inexpensively, and are easy to use by simply placing them on the face. After use, they can be removed from the face and discarded, making them a convenient skin care tool for use at home without having to go to a specialized beauty salon.

[0003] [Patent Document 1] Japanese Patent Application Laid-Open No. 2004-174135 Summary of the Invention [Problem to be solved by the invention]

[0004] However, conventional face packs such as those described in Patent Document 1 have a structure that covers almost the entire face, making it difficult to wear them while engaging in daily activities, going out in public, or working, and there are significant limitations on the places, times, and situations in which they can be used.

[0005] The present invention has been made in consideration of the above-mentioned conventional problems, and one of its purposes is to provide a highly practical facial care tool that can be worn on the face and used on a daily basis without feeling strange, regardless of time, place, or situation, and that can be expected to provide easy facial skin care. [Means for solving the problem]

[0006] In order to solve the above problems, the present invention provides a facial care device comprising a flexible sheet-like body arranged to cover both cheeks, the nose, and the mouth of a person's face; ear loops fixed to both left and right ends of the sheet-like body; and a care member containing a skin care liquid component that is placed on an area on the face side of the sheet-like body corresponding to either one of the cheeks, the nose, or the area around the mouth, or an area corresponding to a combination of these, wherein a waterproof part is provided between the sheet-like body and the care member, and the waterproof part has an engaging part that clamps and holds the outer edge of the care member while exposing the surface of the care member that comes into contact with the face.

[0007] Furthermore, the present invention provides a facial care device comprising a flexible sheet-like body arranged to cover both cheeks, the nose, and the mouth of a person's face; ear loops fixed to both left and right ends of the sheet-like body; and a waterproof part arranged on the facial side of the sheet-like body in a region corresponding to either one of the cheeks, the nose, or the mouth, or a plurality of these regions, which allows a care member containing a skin care liquid component to be placed on and removed from the facial side, and the waterproof part has an engaging part that holds the outer edge of the care member in a clamping manner while exposing the surface of the care member that comes into contact with the face.

[0008] The waterproof portion may also have a waterproof sheet material that is detachable from the sheet-like main body.

[0009] Also, The waterproof portion has a waterproof sheet material that is detachable from the sheet-like main body, The waterproof part and the care member may be assembled to form a waterproof care unit, and the waterproof care unit may be detachably provided on the sheet-like main body. [Effects of the Invention]

[0010] The facial care device of the present invention comprises a flexible sheet-like body arranged to cover both cheeks, the nose, and the mouth of a person's face, ear loops fixed to both left and right ends of the sheet-like body, and a care member containing a skin care liquid component that is placed on the facial side of the sheet-like body in areas corresponding to either or both of the cheeks, the nose, and the mouth. Therefore, the device can be easily worn on the face to provide skin care around the cheeks, nose, and mouth. Furthermore, since the device appears to be simply an ear-hook mask when worn, it can be used for everyday or desired skin care regardless of time, place, or occasion, providing a highly practical face care product.

[0011] Furthermore, by providing a waterproof portion between the sheet-like main body and the care member, it is possible to prevent the skin care liquid components of the care member from wetting the sheet-like main body, thereby maintaining the appearance when worn and also maintaining the durability of the sheet-like main body.

[0012] By configuring the care member to be detachable from the waterproof part, it is possible to provide good skin care by replacing the care member as needed.

[0013] Furthermore, the present invention provides a configuration comprising a flexible sheet-like body designed to cover the cheeks, nose, and mouth of a person's face, ear loops fixed to both left and right ends of the sheet-like body, and a waterproof section provided on the face side of the sheet-like body in areas corresponding to either or both of the cheeks, nose, and mouth, where a care component containing a skin care liquid ingredient can be attached and detached from the waterproof section, thereby enabling skin care around the cheeks, nose, and mouth to be easily applied to the face using the care component containing the desired skin care liquid ingredient. Furthermore, when worn, the face care product looks like a simple ear loop mask, allowing skin care to be performed on a daily basis or on desired occasions regardless of time, place, or occasion, providing a highly practical face care product.

[0014] Furthermore, by configuring the waterproof portion to have a waterproof sheet material that can be attached to and detached from the sheet-like main body, the waterproof portion can be replaced as needed, allowing for satisfactory use.

[0015] Furthermore, by constructing a waterproof care unit in which the waterproof part and the care member are assembled, and by configuring the waterproof care unit to be detachable from the sheet-like main body, it is possible to provide good skin care while replacing the waterproof care unit as needed.

[0016] Furthermore, by configuring the waterproof part to have a locking part that holds the outer edge of the care member in a clamping manner while exposing the surface of the care member that comes into contact with the face, it is possible to specifically realize a structure that allows the care member to be attached, detached, and replaced with a simple structure without interfering with the close contact of the care member with the face.

[0017] Furthermore, by providing the waterproof portion continuously in the areas of the sheet-like body corresponding to both cheeks and nose, a wide area of ​​the face can be cared for at the same time. Furthermore, by providing an additional waterproof portion below the opening of the sheet-like body, i.e., on the lower jaw side, it is possible to prevent the skin care liquid ingredients of the care product from accidentally dripping from below the sheet-like body.

[0019] Hereinafter, an embodiment of the facial care device of the present invention will be described with reference to the accompanying drawings. The facial care device of the present invention is a facial care device that can be easily worn on the face, for example, like an ear mask, and can be used daily or whenever desired for facial skin care without being restricted by place, time, or situation.

[0020] Figures 1, 2, and 3 show a first embodiment of the facial care tool of the present invention. As shown in Figures 1, 2, and 3, the facial care tool 10 according to this embodiment comprises a sheet-like main body 12, ear loops 14, and a care member 16.

[0021] The sheet-like body 12 is a flexible sheet-like covering means designed to cover the cheeks, nose, and mouth of a person's face. In this embodiment, as shown in FIG. 1 , the sheet-like body 12 is a relatively soft, breathable, thin sheet piece, such as a nonwoven fabric, cloth, or gauze, with an approximately rectangular contour. The sheet-like body 12 is preferably sized to cover the wearer's entire cheeks, a portion of the nose, and the area around the mouth and jawline, allowing for skin care over a relatively wide area. The sheet-like body 12, along with the ear loops 14, may have a structure similar to that of a conventionally known sanitary mask or ear loop mask. For example, a mask with a high filtering function to prevent the entry of pollen and viruses can be used to provide skin care while preventing pollen and infection. The sheet-like body 12 is formed by stacking one or more layers of sheets, and may have a structure similar to that of a mask body, such as a flat mask, pleated mask, or three-dimensional mask. In this embodiment, the sheet-like body 12 is illustrated as a flat sheet for the sake of explanation. The material, size, shape, structure, etc. of the sheet-like body 12 may be designed arbitrarily. For example, the sheet-like body 12 may be provided with a size and shape that can adequately cover the face up to the lower jaw. A core material for nose fit may also be provided on the upper edge side of the sheet-like body 12.

[0022] The ear hooks 14 are fixed to both left and right ends of the sheet-like main body 12 and are ear-hook-type face attachment means for attaching the sheet-like main body 12 to the face. In this embodiment, as shown in FIG. 1, the ear hooks 14 are made of a strip-shaped member such as an elastic rubber band or a flexible nonwoven fabric, and both ends are fixed to the upper and lower ends of the left and right ends of the sheet-like main body 12, forming a hole space inside for inserting the ears. Note that the ear hooks 14 may be formed integrally with the sheet-like main body 12 using the same sheet material. The ear hooks 14 may also have a structure that allows for adjustment of their length.

[0023] The care member 16 is a skin care device that is placed on the facial side of the sheet-like body 12 and adheres closely to the face for skin care. In this embodiment, as shown in FIGS. 1 and 2, the care member 16 is made of fibers such as nonwoven fabric, cotton, gauze, or cloth, or a material with high moisture retention or liquid retention (water retention) properties, impregnated with skin care liquid ingredients such as water, moisturizer, cosmetic liquid, or serum. The care member 16 may also be a commercially available beauty mask cut into a predetermined shape. The care member 16 is made of a relatively thin sheet-like member, for example, having a thickness of several tens of microns to several mm, and is formed in a shape and size that matches the desired area to be cared for, such as the cheeks, nose, or mouth area. As shown in FIG. 1, in this embodiment, the care members 16 are placed in pairs at positions corresponding to the left and right cheeks of the face. Specifically, the upper, lower, and outer edges of the care members 16 are set to be approximately the same as the outer edge of the sheet-like body 12, and the edges of the two care members 16 facing each other on the inner side are formed in an arc or linear shape so that the gap between them gradually widens at the bottom, forming an approximately trapezoidal shape.

[0024] In this embodiment, the care member 16 is attached to the face-side surface of the sheet-like body 12 with a waterproof part 18 made of a water-impermeable material interposed therebetween. That is, the waterproof part 18 is provided between the care member 16 and the sheet-like body 12. The care member 16 may also be directly attached to the sheet-like body 12. However, by providing the waterproof part 18 as in this embodiment, it is possible to effectively prevent skin care liquid ingredients in the care member 16 from seeping out into the sheet-like body 12, which could cause an unsightly appearance when worn, or from adhering to areas other than the care member, which could cause discomfort.

[0025] The waterproof section 18 includes a waterproof sheet material 20 made of a water-impermeable, flexible synthetic resin such as a vinyl sheet. The waterproof sheet material 20 is detachably attached via, for example, an adhesive sticker integrally formed on one side of the waterproof sheet material, or a removable attachment means such as double-sided tape, hook-and-loop fasteners, buttons, or hooks. The waterproof sheet material 20 has approximately the same outline shape as the care product 16. The waterproof sheet material 20 may be fixed to the sheet-like body 12 by adhesive, sewing, or the like. The waterproof sheet material 20 may be attached by providing an adhesive surface or the like on the entire sheet surface of the sheet-like body 12 so that it adheres to the entire surface, or by adhering only a portion of the sheet surface to the sheet-like body 12. The waterproof section 18 may also be formed by applying a water-impermeable synthetic resin or the like to the sheet-like body 12 to form an integral waterproof layer.

[0026] Furthermore, the care member 16 is fixed to the waterproof sheet material 20 via a fixing means such as an adhesive. Thus, the care member 16 and the waterproof sheet material 20 forming the waterproof portion 18 are assembled to form a waterproof care unit 22. As shown in FIG. 3, this waterproof care unit 22 is a facial care unit that is detachable from the sheet-like main body 12. For example, the sheet-like main body 12 can be used repeatedly while the waterproof care unit 22 (care member 16) is replaced. The waterproof care unit 22 may be configured such that the care member 16 and the waterproof portion 18 are detachably assembled. Alternatively, the waterproof care unit 22 may be configured such that the waterproof portion 18, consisting of a waterproof layer, is integrally formed by applying a water-impermeable material to the care member 16.

[0027] In another embodiment of the present invention, the care member 16 may be sandwiched and held between the sheet-like body 12 and the face, rather than being fixedly attached to the waterproof part 18. In this case, for example, a facial care tool having the sheet-like body 12, ear loops 14, and waterproof part 18 may be used, and the user may impregnate cotton or cloth of their choice with their preferred skin care liquid, such as lotion or serum, to suit their needs.

[0028] To use the facial care device 10 of this embodiment, for example, a waterproof care unit 22 having a care member 16 impregnated with skin care liquid ingredients is prepared in advance, and the waterproof care unit 22 is attached to the left and right portions of the face-facing surface of the sheet-like body 12, corresponding to the cheeks. The face is then covered with the sheet-like body 12 so that the care member 16 closely contacts the cheeks, and the ear loops 14 are then attached. When the facial care device 10 is attached to the face, it appears similar to a conventional sanitary mask or ear loop mask, allowing for comfortable wearing and skin care. As a result, the time, place, and occasion of use are not restricted, allowing for skin care on a daily basis or at the user's convenience, and improved usability is expected compared to conventional face packs. If the skin care liquid ingredients in the care member 16 run out or dry out, the waterproof care unit 22 can be replaced with a new one.

[0029] The contour shape of the sheet-like body 12 is not limited to a substantially rectangular shape as in the above embodiment, but may be designed to correspond to the area of ​​care to be provided to the wearer's face. For example, as shown in FIG. 4, the contour shape of the upper edge of the sheet-like body 12 may be formed unevenly to better fit a wider area of ​​the face below the eyes. Specifically, the upper edge shape of the sheet-like body 12 is formed convexly around the nose in the left and right central portion (13a), concavely curved in a substantially circular arc in the portion (13b) covering both cheeks below the lower eyelids on both sides, and upwardly curved at both end portions (13c). Furthermore, as shown in FIGS. 4(b) and 4(c), both left and right end edges of the sheet-like body 12 are formed wide enough to be positioned near the wearer's ears and to fully cover both cheeks. Furthermore, the lower side of the sheet-like body 12 is formed wide enough to cover the lower jaw. By forming the sheet-like body 12 in this manner, for example, the lower half (the portion below the eyes) of a conventional face pack or the like can be used as the care member 16. The waterproof portion 18 may be provided on the entire sheet-like body 12. Furthermore, even when the sheet-like body 12 has an outer contour shape as shown in Figure 4, it may have a structure having pleats or the like.

[0030] Furthermore, in the above embodiment, the care member 16 is disposed in areas corresponding to both cheeks. However, as shown in FIG. 5, the care member 16 and the waterproof portion 18 may be disposed in an area corresponding to the nose. As shown in FIG. 6, the care member 16 and the waterproof portion 18 may be disposed in an area corresponding to the area around the mouth. In this case, the care member 16 and the waterproof portion 18 may have holes in the area corresponding to the mouth to facilitate breathing. Furthermore, as shown in the reference example of FIG. 7, the care member 16 and the waterproof portion 18 may be disposed in an area extending from both cheeks to the nose, i.e., in an area excluding the area around the mouth. In the embodiment of FIG. 7, the care member 16 has portions corresponding to both cheeks and the nose integrally formed, and is generally formed in an inverted U shape. In this manner, a facial care tool can be designed with the care member 16 and other components disposed in an area corresponding to the desired facial area.

[0031] Next, a second embodiment of the facial care tool of the present invention will be described with reference to Figures 8 and 9. The same components as those in the above-described embodiment are designated by the same reference numerals, and detailed description thereof will be omitted. In this embodiment, a facial care tool 10-2 includes a sheet-like main body 12, ear loops 14, a care member 16, and a waterproof member 18, as in the above-described embodiment. In this embodiment, the attachment structure of the care member and the waterproof member 18 differs from that of the above-described embodiment.

[0032] The care member 16 and the waterproof member 18 are attached, for example, to portions of the sheet-like body 12 corresponding to both cheek portions. In this embodiment, the care member is provided detachably with respect to the waterproof member 18. Specifically, the waterproof member 18 has a waterproof sheet material 20 made of a water-impermeable sheet such as a vinyl material, and is fixed to the sheet-like body 12.

[0033] As shown in Figures 8 and 9, the waterproof sheet 20 has locking pieces 24 on both the left and right edges and the bottom edge to hold and engage the edges of the care component 16. That is, the locking pieces 24 are provided in a roughly U-shape along the edges of the waterproof sheet 20, forming locking portions 26 that hold the care component 16 while leaving most of the central portion of the care component 16 exposed, which is the surface that comes into contact with the face. This allows the care component 16 to be easily attached, detached, and replaced on the sheet-like body 12. The locking pieces 24 are, for example, made of the same material as the waterproof sheet 20 and formed in a narrow strip shape. While the outer periphery is integrally fixed to the waterproof sheet 20, the outer edge of the care component 16 is received between the opposing surfaces of the waterproof sheet 20 and the locking pieces 24, thereby holding and engaging the care component 16 in place. The waterproof sheet 20 may also be detachably attached to the sheet-like body 12. The locking pieces 24 may also be formed of a water-permeable material. In this case, the skin care liquid ingredients can be permeated from the care member 16 into the facial skin via the engaging pieces 24. Alternatively, the waterproof sheet material 20 may not be provided on the sheet-like main body 12, but the engaging pieces 24 may be attached, and the waterproof care unit 22 may be detachably attached via the engaging pieces 24.

[0034] This embodiment also provides the same advantageous effects as the above-described embodiments, such as being able to wear the care member 16 comfortably and perform skin care routinely or at a time of the user's choosing, regardless of time, place, or occasion. Furthermore, the care member 16 can be made of a material and contains skin care liquid components of the user's choice. Furthermore, the fastening portion 26 is designed to cover the lower edge of the care member 16, effectively preventing dripping of the care member. As a result, it is possible to prevent the skin care liquid from dripping from the care member 16, causing discomfort due to wetting areas other than the area being treated, or staining the user's clothing.

[0035] As shown in Fig. 10, the care member 16 of this embodiment may be configured to be detachably attached to the waterproof member 18 via the fastening portion 26, with the waterproof member 18 and the care member 16 being provided in a region corresponding to the nose. Also, as shown in Figs. 11 and 12, the care member 16 of this embodiment may be configured to be detachably attached to the waterproof member 18 via the fastening portion 26, with the waterproof member 18 and the care member 16 being provided in a region extending continuously from both cheeks to the nose. In the embodiment shown in Fig. 11, the care member 16 has portions corresponding to both cheeks and the nose formed integrally. In the embodiment shown in Fig. 12, the care member 16 is formed separately into a region corresponding to the cheeks and a region corresponding to the nose, each of which is detachably attached to the fastening portion 26 of the waterproof member 18.

[0036] Next, a reference example of a facial care tool of the present invention will be described with reference to Figure 13. The same components as those in the above-described embodiment are designated by the same reference numerals, and detailed description will be omitted. In this reference example, a facial care tool 10-3 includes a sheet-like main body 12, ear loops 14, a care member 16, and a waterproof member 18, just like the above-described embodiment. In this reference example, the attachment structure of the care member 16 and the waterproof member 18 differs from that of the above-described embodiment.

[0037] In this reference example, the sheet-like body 12 has a structure with multiple pleats, such as a pleated mask. The pleats are not shown. As shown in Fig. 13(a), the care member 16 and the waterproof part 18 are provided on the facial side of the sheet-like body 12 in areas corresponding to the cheeks, nose, and mouth, allowing skin care over a wide area of ​​the lower half of the face.

[0038] The care members 16 and waterproof members 18 corresponding to both cheeks are aligned with their lower edges 161 when the pleats of the sheet-like main body 12 are folded. The lower edges of the care members 16 and waterproof members 18 are sized to cover the lower sides of both cheeks and the lower edge of the lower jaw. As shown in FIG. 13(b), when the pleats of the sheet-like main body 12 are unfolded, the care members 162 and waterproof members 18 corresponding to the mouth area are shifted slightly downward, so that the care members 162 around the mouth area are positioned approximately in line with the lower edges 161 of the care members 16 corresponding to both cheeks, and are in close contact with the lower jaw of the mouth area. This allows the care members 16 to fit closely along the lower edge of the lower jaw, preventing unexpected dripping of the skin care liquid components of the care members 16 from below. When the sheet-like body 12 has a flat sheet structure, a care member 16 and a waterproof part 18 may be provided along the lower edge of the sheet-like body 12 to prevent dripping.

[0039] This reference example can also achieve the same effects as the above-mentioned embodiments, such as being able to wear it comfortably and perform skin care on a daily basis or at a time of the user's choosing, regardless of time, place, situation, etc.

[0040] The facial care tool of the present invention described above is not limited to the configuration of the above-mentioned embodiment, and any modifications may be made without departing from the essence of the present invention as set forth in the claims. [Explanation of symbols]
