Description

[Technical Field]

[0001] The present invention relates to a mimetic muscle contraction / stretching inducing member for promoting contraction or relaxation of mimetic muscles, a face pack, and a face pack set. [Background technology]

[0002] Because facial skin is supported by mimetic muscles, weakening of the mimetic muscles due to aging, lack of facial expression (reduced use), etc. can lead to sagging skin and wrinkles. For this reason, various beauty rollers have been proposed as facial massage tools to stimulate the mimetic muscles. For example, Patent Document 1 discloses a beauty roller that includes a pair of arms extending from a grip and bifurcating at their distal ends, a pair of rollers rotatably supported on the distal ends of each arm, and a positive electrode and a negative electrode around each roller for applying electrical stimulation to the muscles through EMS (neuromuscular electrical stimulation therapy). According to this, when a user holds the beauty roller by its grip and rolls the roller in contact with the user's skin, the mimetic muscles can be stimulated by pressure from the rollers and electrical stimulation through EMS. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Japanese Patent Application Publication No. 2019-193726 Summary of the Invention [Problem to be solved by the invention]

[0004] However, when using the beauty roller to stimulate the facial muscles, the user must hold the grip of the beauty roller in one hand and continue to roll the roller while bringing it into contact with the user's skin surface, and when the user feels tired while operating with one hand, the user must switch the grip to the other hand, and if the operation is continued for a long time, the user must repeat this switching operation. Therefore, the user's operational burden is not light, and furthermore, the user must be almost entirely focused on the beauty roller while using it, so it must be said that there is room for improvement in terms of ease of use of the beauty roller.

[0005] Moreover, a beauty roller is basically a beauty tool that has a pair of arms that extend from a grip and branch into two at the tip, and a pair of rollers that are rotatably supported on the tip of each arm.In addition, each of the pair of rollers is equipped with a positive electrode and a negative electrode around it to apply EMS electrical stimulation to the muscles.In order to obtain such a device, one must be prepared to incur a corresponding expense, and the above-mentioned beauty roller is not something that anyone can easily obtain.

[0006] Under these circumstances, the present inventors have focused on the following points. (i) If the facial muscles can be contracted or relaxed appropriately depending on the facial muscles in each part of the face, it will be possible to improve sagging skin and wrinkles on the face (lifting effect) and increase skin firmness. (ii) On the other hand, humans can sometimes experience a kinesthetic illusion in which they perceive muscle movement due to external stimuli, even though the muscles are not actually moving, either voluntarily or passively. The use of this kinesthetic illusion in rehabilitation has begun to be explored ("Cutaneous Receptors Contribute to Kinesthesia at the Index Finger, Elbow, and Knee": D.F. Collins, K.M. Reffshauge, G. Todd, and S.C. Gandevaia; "The Effects of Muscle Vibration and Skin Cold Stimulation During Simultaneous Extension Movement of the Hand and Elbow Joints on Motor Control": Seki Hiroyuki and Muro Masuo). If this kinesthetic illusion could be utilized to train facial muscles, it could be expected to improve facial skin sagging and wrinkles (a lifting effect).

[0007] (iii) To apply a kinesthetic illusion to the facial muscles, one possible approach is to utilize the Ruffini endings present in the skin (dermis) as tactile receptors. Ruffini endings sense the direction and force of even a very small tensile force (such as an unconscious tensile force that the user cannot feel) acting on the skin (skin surface). As long as they sense this force, they continuously send information about the tensile force to the brain. The sensory function of Ruffini endings supports the sense of movement. Therefore, by using Ruffini endings to continuously send information about the tensile force to the brain, the brain can be made to perceive the facial muscles as moving in the direction of the tensile force acting on the skin, even though the facial muscles are not actually moving voluntarily or passively (kinesthetic illusion). Based on this kinesthetic illusion, the facial muscles can be continuously encouraged to move in the direction of the kinesthetic illusion (transmission from the brain to the facial muscles via neural circuits).

[0008] (iv) Therefore, if it were possible to generate an unconscious tensile force on the skin surface continuously, to an extent that the user does not feel it, and if it were possible to easily determine the direction of the tensile force freely while taking into account the direction of the muscles, as described above, it would be possible to generate a kinesthetic illusion using the Ruffini endings, and based on this kinesthetic illusion, it would be possible to encourage the facial muscles to move in a manner similar to that kinesthetic illusion.As a result, it would be possible to train the facial muscles without continuously applying an operating force to the skin using a beauty roller or the like (while ensuring ease of use), and by supporting the skin with the facial muscles, it would be possible to expect improvements in sagging skin and wrinkles.

[0009] The present invention has been made in consideration of the above circumstances, and its first object is to provide a mimetic muscle stretch-inducing member that can promote contraction or relaxation of mimetic muscles to be improved while ensuring ease of availability and ease of use that does not cause the user to feel burdened. The second object is to provide a face pack that can be easily used as the mimetic muscle stretch-inducing member. The third object is to provide a face pack set that allows a face pack to also be used as the mimetic muscle stretch-inducing member.

[0010] In order to achieve the first object, the present invention provides the following (1) to (3): (4) It is structured as follows.

[0011] (1) Place it along the surface of your face to cover the face in a predetermined position. A sheet-like substrate is provided, an external force-applying portion formed in a stretched state is provided on the sheet-like substrate, the external force application unit comprises a cut that is cut from the inner surface of the sheet-like substrate to the surface thereof and extends linearly, and a liquid component that is held on at least the inner surface of the sheet-like substrate including the area where the cut is present; the sheet-like substrate is formed in an area corresponding to at least one facial muscle so that the entire cut is aligned along the running direction of the assumed facial muscle in the corresponding area, The incisions and the liquid component are configured so that, on condition that the inner surface of the sheet-like substrate is placed on the skin surface and the incisions are open, the liquid component is condensed and a force based on the surface tension of the liquid component is applied to the skin surface in a direction along the skin surface and inward in the extension direction of the incisions. It is considered to be composed.

[0012] According to this configuration, when the inner surface of the sheet-like substrate is placed on the skin surface of the face, the external force application unit applies an external force to the skin surface in a direction along the skin surface and in the direction of extension of the external force application unit. Therefore, if it is desired to stimulate a movement based on a kinesthetic illusion using the Ruffini endings in a target mimic muscle, the external force application unit is placed in the skin surface area facing the target mimic muscle. By visually grasping the extension of the external force application unit during placement, the direction of application of the external force by the external force application unit can be oriented in a direction effective for the target mimic muscle. Based on the external force applied by the external force application unit to the skin surface, a desired tensile force (which is also a shear force between the interior of the skin and the skin surface) can be generated on the skin surface. This tensile force and its direction on the skin surface are transmitted from the corticospinal tract via the Ruffini endings to the motor cortex of the brain. Based on this, the motor cortex of the brain generates a kinesthetic illusion and stimulates the mimic muscle to move based on the information from the Ruffini endings. This allows appropriate stimulation of contraction or relaxation of the target mimic muscle. Moreover, in this case, a simple sheet-like substrate provided with only an external force application section is used, and it is sufficient to simply place it on the skin surface (the area opposite the facial muscle to be improved), so it is easy to obtain and convenient, and at the same time, it is easy to use and does not cause any burden to the user.

[0013] Also, Under the above-mentioned configuration (1), The external force application section is configured to include a cut that extends linearly from the inner surface to the surface of the sheet-like substrate, and a liquid component that is held on at least the inner surface of the sheet-like substrate, including the area where the cut exists.

[0014] From this,When the inner surface of the sheet-like substrate is placed on the skin surface, the liquid components on the inner surface of the sheet-like substrate and the liquid components that have wetted the skin surface are exposed to the outside surface (open air) of the sheet-like substrate through the cuts (including both those that are open from the beginning and those that open due to the curved surface of the skin surface), and the exposed liquid components condense to reduce their surface area, generating surface tension in the liquid component portion. At this time, because the sheet-like substrate utilizes the elongation shape of the cuts to make its deformation resistance in the elongation direction much smaller than its deformation resistance in the width direction of the cuts (the direction perpendicular to the elongation direction), the force of aggregation due to the surface tension of the liquid components tries to deform the sheet-like substrate from both ends of the elongation direction of the cut toward the inside in the elongation direction of the cut so as to shorten the length of the cut (as if compressing it), and this deformation force of the sheet-like substrate is transmitted to the skin surface via the liquid components adhering to the skin surface, and a slight tensile force (an unconscious tensile force that the user does not feel) acts on the skin surface toward the inside in the elongation direction of the cut. This tensile force on the skin surface is sent to the brain using the Ruffini endings, so by applying the tensile force on the skin surface based on the surface tension of the liquid component to the skin surface facing the target facial muscle, taking into account the direction in which the muscle runs, and in a state appropriate to the muscle, it is possible to train the facial muscle and improve sagging skin and wrinkles. Furthermore, under the above-mentioned configuration (1), The sheet-like substrate is intended to cover the face in a predetermined state, The sheet-like substrate for the face is configured such that, within an area corresponding to at least one facial muscle on the face, the entire cut is formed along the direction in which the expected facial muscle runs in the corresponding area. As a result, since the sheet-like substrate is placed on the face in a predetermined state, the corresponding area and running direction of the facial muscles can be set in advance on the sheet-like substrate based on commonly known information about facial muscles. In the area corresponding to at least one of the facial muscles, a cut is formed throughout the entire surface, aligning with the running direction of the assumed facial muscle in that corresponding area. Therefore, when the sheet-like substrate is placed on the face in a predetermined state, a tensile force based on the surface tension of the liquid component can be generated on the skin surface in contact with the corresponding area where the cut is formed, directed inward in the direction of the extension of the cut. The Ruffini endings sense this tensile force and its direction, and contraction of the assumed facial muscle in the corresponding area is promoted through a kinesthetic illusion. At this time, a tensile force acts on the skin surface of the corresponding area from both sides of the incision in the inward direction of stretching, and based on the illusion of movement, the assumed facial muscles are encouraged to move not only from their insertion side to their origin side, but also from their origin side to their insertion side.However, when the muscles contract, the insertion (part) of the muscle acts as the part with the largest movement, and the origin (part) of the muscle acts as the part with the smallest movement, so the movement from the insertion side of the assumed facial muscles to the origin side (displacement movement) is relatively larger than the movement from the origin side of the assumed facial muscles to the insertion side, encouraging contraction of the assumed facial muscles.This makes it possible to train the assumed facial muscles of the corresponding area, and to improve sagging and wrinkles on the skin surface in that corresponding area.

[0015] (2) The aforementioned (1) Under the configuration of The sheet-like substrate is entirely impregnated with the liquid component.

[0016] According to this configuration, when used, a sufficient amount of liquid component is supplied to the slit opening and the inner surface of the sheet-like substrate, and the above-mentioned liquid component due to the surface tension at the slit opening is prevented. (1) This can ensure the effectiveness of the method.

[0017]

[0018]

[0019] (3) The aforementioned (1) Under the configuration of The number of the cuts in the corresponding region is plural.

[0020] With this configuration, even if the corresponding area (the area of ​​the assumed facial muscles) is wide, the tensile force (load) on the skin surface in contact with the corresponding area can be increased simply and effectively by the multiple cuts.

[0021] (4) The aforementioned (1) Under the configuration of The sheet-like substrate is The sheet-like substrate for a face pack has openings in areas corresponding to at least the eyes and mouth, The liquid component is a beauty serum.

[0022] According to this configuration, by aligning the eyes and mouth with the openings in the sheet substrate for a face pack, the sheet substrate for a face pack can be positioned in a predetermined state on the face, and based on this positioning, the area and running direction of the facial muscles in the sheet substrate for a face pack can be accurately identified, and in that corresponding area (sheet substrate for a face pack), cuts can be accurately formed that correspond to the expected facial muscles. Therefore, while aiming to use it as a face pack, it is possible to accurately improve sagging skin and wrinkles in the corresponding area on the face.

[0023]

[0024]

[0025] In order to achieve the second object, the present invention provides the following: (5) It is structured as follows.

[0026] (5) For placement on the skin of the faceA sheet-like substrate for a face pack having openings in areas corresponding to at least the eyes and mouth, and at least The beauty serum is retained inside, In preparation for this, it is possible to induce the contraction of facial muscles. A face pack, The surface of the sheet-like substrate for a face pack is provided with an area corresponding to at least one of the facial muscles. Inside In the notch display The whole of is displayed along the direction of the assumed facial muscles in the corresponding area. The notch display is selectively cuttable, When a cut is made along the cut indication to form a cut in the sheet-like substrate for a face pack, the cut and the beauty serum are configured to condense the beauty serum and apply a force based on the surface tension of the beauty serum to the skin surface in a direction along the skin surface and inward in the extension direction of the cut, provided that the inner surface of the sheet-like substrate for a face pack is placed on the skin surface and the cut opens. It is considered to be composed.

[0027] With this configuration, the user can make cuts according to the cut markings on the surface of the sheet-like substrate for a face pack, and based on the cut selection, a face pack having cuts that induce movement (contraction) of the mimetic muscles based on a kinesthetic illusion using the Ruffini endings can be easily obtained. This allows the user to train the mimetic muscles according to their own situation.

[0028] In order to achieve the third object, the present invention provides the following: (6) It is structured as follows.

[0029] (6) A face pack set used to induce the contraction of facial muscles, For placement on the skin surface of the face a face pack having a sheet-like substrate for a face pack, the sheet-like substrate having openings in at least the areas corresponding to the eyes and mouth, and a beauty serum held at least on the inner surface thereof; On the surface of the face pack, In order to guide the cuts for the face pack, the face pack is fitted to the face pack and covers the entire face pack. Can be stacked in different states Transparent or translucent A cutting guide sheet is provided, The cutting guide sheet has a corresponding area of ​​at least one of the facial muscles. Inside In the notch display The whole of is displayed along the direction of the assumed facial muscles in the corresponding area. And, When the incision guide sheet is placed on the surface of the face pack to correspond to the face pack and cover the entire face pack, and an incision is formed in the face pack by making an incision in the incision guide sheet and the face pack from the incision mark on the incision guide sheet, the incision in the face pack and the beauty serum are configured to condense the beauty serum and apply a force based on the surface tension of the beauty serum to the skin surface in a direction along the skin surface and inward in the extension direction of the incision, provided that the inner surface of the sheet-like substrate for face pack is placed on the skin surface and the incision is open. It is considered to be composed.

[0030] With this configuration, by placing the incision guide sheet on the surface of an existing face pack and then making incisions according to the incision indications on the incision guide sheet, it is possible to easily obtain a face pack that uses the existing face pack while having incisions that induce the movement (contraction) of the facial muscles based on a kinesthetic illusion using the Ruffini endings. Moreover, in this case, the incision indication can be selected according to the user's situation, allowing the user to train the facial muscles according to their own situation. [Effects of the Invention]

It is also possible to provide a face pack that can be easily used as the mimetic muscle stretch-inducing member. Furthermore, it is possible to provide a face pack set that allows a face pack to be used as the mimetic muscle stretch-inducing member. [Brief explanation of the drawings]

[0033] Hereinafter, an embodiment of the present invention will be described with reference to the drawings.

[0034] In FIGS. 1 and 2, reference numeral 1 denotes a face pack used as a mimetic muscle contraction / contraction-inducing member according to the first embodiment. This face pack 1 includes a sheet-like substrate for a face pack (hereinafter referred to as sheet-like substrate) 2, which is a sheet-like substrate (face sheet-like substrate) designed to cover the face of an average adult, and a liquid component, a beauty serum 3, impregnated into the sheet-like substrate 2 and retained on the inner surface of the sheet-like substrate 2. The sheet-like substrate 2 is formed to a certain thickness using nonwoven fabric, and the nonwoven fabric contains ultrafine fibers to enhance the impregnation performance of the beauty serum 3. The sheet-like substrate 2 has openings 4 and 5 formed in areas corresponding to the eyes and mouth, respectively, and a slit 6 formed to accommodate the nose protruding from the face. When a user aligns their eyes with the opening 4 of the sheet-like substrate 2, pushes up the area defined by the slit 6 with their nose, and then inserts their mouth into the opening 5, the sheet-like substrate 2 is positioned in a predetermined state relative to the user's face.

[0035] In this embodiment, as shown in FIG. 2 , the entire sheet-like substrate 2 is impregnated with the serum 3, wetting not only the inner surface but also the outer surface of the sheet-like substrate 2. In FIG. 2 , the presence of the serum 3 is exaggerated somewhat to clarify its presence and contents. The sheet-like substrate 2 impregnated with the serum 3 is stored in a sealed packaging bag before use and is removed from the sealed packaging bag upon use. Since the serum 3 essentially serves to supply nutrients to the skin surface, it is generally a liquid containing moisturizing ingredients such as hyaluronic acid, ceramide, and glycerin, as well as whitening ingredients such as vitamin C derivatives, arbutin, and tranexamic acid. However, from the perspective of improving sagging and wrinkles on the skin surface, as described below, it is preferable to minimize ingredients that enhance surfactant effects and instead increase surface tension.

[0036] 3, in the sheet-like substrate 2, corresponding regions 7 (used as representative symbols for the corresponding regions) of various facial muscles and the assumed running direction of the facial muscles in each corresponding region 7 are identified. This is to allow the action of incisions 10, which will be described later, to be effectively exerted on the selected facial muscles. In identifying the corresponding regions 7 of the various facial muscles and the assumed running direction of the facial muscles in each corresponding region 7 in the sheet-like substrate 2, existing knowledge and information regarding the locations and running directions of the various facial muscles on the human face are used, on the premise that the sheet-like substrate 2 will be used in correspondence with the human face in the predetermined state.

[0037] 4, various facial muscles 8 (used as a representative symbol for the facial muscles) on the human face include the frontalis muscle 8a in the forehead, the orbicularis oculi muscle 8b around the eyes, the zygomatic major muscle 8c around the mouth, and the laughing muscle 8d, and each of these facial muscles 8 has its own running direction, and the corresponding regions 7 of the various facial muscles in the sheet-like base material 2 and the running directions of the assumed facial muscles in each corresponding region 7 are grasped in a state corresponding to the actual arrangement regions and running directions of the various facial muscles 8. This grasped information is incorporated as setting information to be used when forming the incisions 10 (described below) in a processing device such as a press used to cut out the sheet-like base material 2 from a material and to form the openings 4 and 5 for the eyes and mouth in the sheet-like base material 2 and the incision 6 for defining the nose region. For this reason, in Fig. 3, for the sake of convenience, some of the assumed regions 7 of various facial muscles are indicated by dashed lines, but in this embodiment, the corresponding regions 7 of various facial muscles 8 and the indication of the running direction of the assumed facial muscles in each corresponding region 7 are not displayed on the sheet-like substrate 2. Note that the term "assumed facial muscles" in the corresponding regions 7 is used to mean the same as the facial muscles 8 that face the corresponding regions 7 when the sheet-like substrate 2 is placed on the face, but is also used to identify the facial muscles 8 in consideration of the case where the sheet-like substrate 2 is not placed on the face. For this reason, the same symbols as the facial muscles 8 are used for the assumed facial muscles.

[0038] The face pack 1 (sheet-like substrate 2) has linear cuts 10 formed therein, as shown in Figures 1, 3, and 5. When the face pack 1 is placed on the skin surface 12 of the face, a surface tension ST is generated by the serum 3 impregnated in the face pack 1 and the cuts 10, and this surface tension ST causes a tensile force P (used as a representative symbol for tensile force) to act on the skin surface 12 inward in the extension direction of the cuts 10 via the serum 3 on the inner surface of the sheet-like substrate 2. The cuts 10 are formed by a processing device such as a press simultaneously with the cutting of the sheet-like substrate 2 from a material, the formation of the openings 4 and 5 for the eyes and mouth in the sheet-like substrate 2, and the formation of the incision 6 for defining the nose area.

[0039] 5, the incisions 10 extend linearly from the inner surface of the sheet-like substrate 2 to the surface, and when the sheet-like substrate 2 is placed on the facial skin surface 12, the butt joints (peripheral edges) 10a of the incisions 10 open due to the curved surface of the facial skin surface 12, thereby forming slit-like openings 10b that extend in the direction of the incisions 10 with the inner surface of the sheet-like substrate 2 facing outward. When the face pack 1 is placed, the serum 3 on the skin surface 12 moistened by the face pack 1, the serum 3 oozing from the face pack 1, and the like enter into the openings 10b of the incisions 10, and the serum 3 is kept filled in the openings 10b, but the serum 3 in the openings 10b is exposed to the outside (atmosphere). 6, a surface tension ST is generated in the serum 3 inside the opening 10b, causing it to condense, and based on this surface tension ST, a tensile force P acts as an external force inward in the elongation direction of the incision 10 on the skin surface 12 via the serum 3 on the inner surface of the sheet-like substrate 2. For this reason, the width and length in the elongation direction of the opening 10b are set so as to generate surface tension ST and maintain the opening 10b filled with the serum 3 based on the adhesive force of the serum 3 to the inner surface of the opening 10b.

[0040] As shown in Fig. 3, the incisions 10 are formed throughout the corresponding regions 7 of the various facial muscles 8, along the direction in which the assumed facial muscles 8 run in the corresponding regions 7. The incisions 10 are formed in the corresponding regions 7 so that the action of the incisions 10 can be effectively exerted on the assumed facial muscles 8 in the corresponding regions 7 (the facial muscles facing the corresponding regions 7 when the sheet-like substrate 2 is placed on the skin surface 12). The incisions 10 are formed along the direction in which the assumed facial muscles 8 run in the corresponding regions 7 so that the tensile force P acting inward in the stretching direction of the incisions 10 can be used as a force acting on the skin surface 12 in the stretching direction of the assumed facial muscles 8.

[0041] The reason for forming the incision 10 over the entire corresponding region 7 is to apply a tensile force P1 (P) in at least the direction from the MT side of the assumed mimic muscle 8 toward the MI side of its origin (origin direction) to the skin surface 12 that comes into contact with the corresponding region 7, in order to contract the assumed mimic muscle 8 in that corresponding region 7, as shown in Fig. 6. In other words, the origin of the mimic muscle 8 is basically the fixed side, and the insertion is the side that is most easily movable, and when the mimic muscle 8 contracts, it mainly moves in the direction from the MT side of its origin toward the MI side of its origin (origin MI direction). For this reason, when creating a motor illusion based on the tensile force P acting on the skin surface 12, of the tensile forces P1 and P2 acting on the skin surface 12 (tensile forces directed inward from both sides of the stretching direction of the incision 10), at least one force P1 is required that is directed from the insertion MT side of the imagined facial muscle 8 toward the origin MI. When this tensile force P1 acts on the skin surface 12, it is sent from the corticospinal tract via the Ruffini endings 13 to the motor cortex of the brain 14, and based on this, the motor cortex of the brain 14 creates a motor illusion and, based on the information from the Ruffini endings 13, encourages the imagined facial muscle 8 to move from the insertion MT side toward the origin MI. At the same time, even if a tensile force P2 in the direction from the origin MI side of the assumed facial muscle 8 toward the insertion MT side acts on the skin surface 12, urging the assumed facial muscle 8 to move from its origin MI side toward its insertion MT side, based on the relationship between origin MI and insertion MT when the facial muscle contracts, the urging of the assumed facial muscle 8 from the insertion MT side toward the origin MI side will effectively work, and the assumed facial muscle 8 will contract (the length of the arrow in the assumed facial muscle 8 in Figure 6 indicates the amount of displacement). Note that many Ruffini endings 13 are present in the subcutaneous tissue 11c of the skin 11 (epidermis 11a, dermis 11b, subcutaneous tissue 11c).

[0042] As shown in Fig. 3, the incisions 10 are formed in one or more assumed regions 7 selected from the assumed regions 7 of various facial muscles 8 in the sheet-like substrate 2. This is to accommodate the user's facial condition, such as when contracting one facial muscle to train it alone, or when combining contractions and relaxations of multiple facial muscles to effectively lift the face. In this embodiment, the regions 7 corresponding to the frontalis muscle 8a, zygomaticus major muscle 8c, laughing muscle 8d, and orbicularis oculi muscle 8b are selected, and incisions 10 are formed in each of the assumed regions 7a, 7c, and 7d symmetrically with respect to the center line of the sheet-like substrate 2, and each incision 10 is arranged along the running direction of the respective assumed facial muscle 8a, 8c, and 8d.

[0043] However, with regard to the incision 10 formed in the region 7b corresponding to the orbicularis oculi muscle 8b, one portion is positioned in the upper part of the assumed region 7b so as to be perpendicular to the orbicularis oculi muscle 8b as the assumed facial muscle 8, while the other portion extends diagonally outward from the upper part of the region 7b corresponding to the orbicularis oculi muscle 8b. This is because the orbicularis oculi muscle 8b has the effect of closing the eyes, and arranging the incision 10 along the direction of the muscle's course would promote contraction of the orbicularis oculi muscle 8b and create wrinkles at the corners of the eyes. Therefore, in order to suppress the creation of wrinkles at the corners of the eyes, the incision 10 is extended perpendicular to the orbicularis oculi muscle 8b, thereby relaxing the orbicularis oculi muscle 8b. At the same time, this can promote contraction of the frontalis muscle 8a via the connective tissue 8e (see Figure 4) between the orbicularis oculi muscle and the frontalis muscle, and this fact is utilized to lift the space between the eyebrows, making it easier to open the eyes and lift the corners of the eyes.

[0044] Furthermore, multiple incisions 10 are formed in one corresponding region 7 as necessary. This is to take into consideration the fact that when the area occupied by the selected mimic muscle 8 is large, a tensile force P based on surface tension ST is effectively applied to the skin surface 12 in contact with the corresponding region 7 of that mimic muscle 8. For this reason, in this embodiment, two incisions 10 are formed in parallel along the frontalis muscle 8a in the corresponding region 7a of the frontalis muscle 8a (see FIG. 3).

[0045] Next, the operation of the face pack 1 will be explained with reference to Figures 5 and 6. The explanation will focus on the case where one incision 10 is arranged in the area 7 of the face pack 1 corresponding to one facial muscle.

[0046] When the face pack 1 is placed on the user's face and positioned in a predetermined state relative to the user's face, the slits 10 open based on the curved surface of the facial skin surface 12, forming openings 10b through which the inner surface of the sheet-like substrate 2 faces the outside. As a result, the serum 3 on the skin surface 12 wetted by the face pack 1, the serum 3 that has seeped out of the face pack 1, and the like enter openings 10b, and the serum 3 filled in openings 10b is exposed to the outside (atmosphere) (see FIG. 5). This exposed serum 3 condenses to reduce its surface area, and surface tension ST is generated in the portion of the serum 3. At this time, by utilizing the elongation form of the incisions 10 in the sheet-like substrate 2, the deformation resistance in the elongation direction is made much smaller than the deformation resistance in the width direction of the incisions 10 (the direction perpendicular to the elongation direction), and therefore the cohesive force due to the surface tension ST of the serum 3 is transmitted to the serum 3 attached to the sheet-like substrate 2 continuous with the serum 3, thereby deforming the sheet-like substrate 2 from both ends of the incisions 10 in the elongation direction toward the inside of the incisions 10 so as to shorten (compress) the length of the incisions 10. The deformation force of the sheet-like substrate 2 at this time is transmitted to the skin surface 12 via the serum 3 attached to the inner surface of the sheet-like substrate 2, and this transmitted force acts as a tensile force P on the skin surface 12 (see Figure 6).

[0047] As a result, a minute tensile force P (this is an unconscious tensile force that is not felt by the user and is also a shear force between the inside of the skin and the skin surface) acting continuously inward in the direction of extension of the incision 10 acts on the skin surface 12 in contact with the corresponding region 7 where the incision 10 is formed. Moreover, at this time, because the incision 10 extends in the direction of the running of the imagined facial muscles 8 in the corresponding region 7 of the facial muscles, a tensile force P is applied to the skin surface 12 in contact with the corresponding region in the running direction of the facial muscles facing the skin surface 12. This tensile force P on the skin surface 12 and its direction are sent to the brain 14 using the Ruffini endings 13 (sent from the corticospinal tract via the Ruffini endings 13 to the motor cortex of the brain 14), so the motor cortex of the brain 14 creates a movement illusion and prompts the facial muscles 8 to move based on the information from the Ruffini endings 13 (see Figure 6).

[0048] At this time, a tensile force P acts on the skin surface 12 in contact with the corresponding area 7 from both sides of the incision 10 in the inward direction of stretching, and based on the kinesthetic illusion, the imagined facial muscle 8 is encouraged to move not only from its insertion MT side toward the origin MI, but also from the origin MI side toward the insertion MT side. However, when the muscle contracts, the insertion MT (part) of the muscle acts as the part with the largest movement, and the origin MI (part) of the muscle acts as the part with the smallest movement (fixed side), so the movement of the imagined facial muscle 8 from its insertion MT side toward the origin MI is dominant, and the imagined facial muscle 8 contracts. As a result, the imagined facial muscle 8 in the corresponding area 7 is contracted and trained, and sagging and wrinkles on the skin surface 12 in the corresponding area 7 can be improved (see Figure 6).

[0049] One possible method for applying tension to the skin surface 12 is to apply tension to the skin surface while applying a bandage to the skin surface, thereby maintaining the tension on the skin surface. However, the tension exerted by muscles is affected by changes in muscle length. The tension generated by muscle contraction is greatest at its natural length, and as the length decreases from the natural length, the active tension decreases. Furthermore, when the length decreases below 60% of the natural length, the active tension cannot be exerted. In other words, applying tension to the skin with a bandage shortens the muscle length, preventing the muscle from exerting active tension and hindering the contraction of the facial muscles. In contrast, the method of this embodiment does not apply tension to the skin surface to shorten the muscle length, but instead uses the action of the skin's sensory receptors based on the incisions (surface tension) to induce a kinesthetic illusion in the facial muscles, encouraging muscle contraction. This encourages muscle contraction from its natural length, generating active tension and enhancing the function of the facial muscles. Of course, the method according to this embodiment has advantages over the method using a bandage in that it does not require the application of pulling force to the skin surface with the hands or the like, and the user does not feel the pulling force.

[0050] Figures 7 to 9 show a surface tension confirmation experiment that confirms that a surface tension ST is generated between the cut 10 in the sheet-like substrate 2 and water (used as an equivalent to the beauty serum 3), and that this surface tension ST causes the cut 10 to shorten inward in the extension direction of the cut 10.

[0051] (surface tension confirmation experiment) For the experiment, as shown in FIGS. 7 and 8 , a sample piece (Ls = 57 mm, Lw = 25 mm, Lt = 0.3 mm) 16 was cut out from the sheet-like substrate 2 used in the face pack 1, and a linear slit (Ss = 23 mm, Sw = 0.3 mm) 17 was formed in the sample piece 16 as the cut line 10. The sample piece 16 was then immersed in purified water to impregnate the sample piece 16 with purified water, and the slit 17 was filled with purified water and held therein. The sample piece was then placed on a glass substrate 18. Thereafter, the changes over time in the lateral length Ls of the sample piece 16 and the lateral length Ss of the slit 17 were measured. Because the amount of displacement during measurement was expected to be small, the sample was photographed with a digital camera (LUMEX, manufactured by Panasonic) at each measurement point, and the lateral length Ls of the sample piece 16 and the lateral length Ss of the slit 17 in each photographed image were measured using image analysis software (ImageJ).

[0052] 9 shows the experimental results, which confirmed that the lateral length Ls of the sample piece 16 and the lateral length Ss of the slit 17 began to shorten about five minutes after the start of the experiment.

[0053] Figures 10 to 13 show the results of a test on the difference in height between the corners of the eyes and the corners of the mouth when using two types of face packs: a face pack (with cut 10) according to the first embodiment (see Figure 1) as the example face pack, and a face pack in which the cut 10 has been removed from the face pack according to the first embodiment as the comparative face pack.

[0054] (1) Measurement conditions The face pack according to the comparative example was immersed in purified water, and the subject wore the face pack according to the comparative example for 10 minutes. After the photograph, the subject took a two-minute break, and then wore the face pack according to the example, which had also been immersed in purified water, on the face for 10 minutes. After that, the face pack according to the example was removed and the face photographed. Each photographed image was then analyzed to derive the heights h (h1, h2) of the corners of the eyes and m (m1, m2) of the corners of the mouth, as described below.

[0055] (2) Subjects 4 adults.

[0056] (3) Equipment used and how to use it The above measurements were taken using a digital camera (LUMEX, manufactured by Panasonic) with the subject sitting still with both arms hanging down. The distance between the digital camera and the subject was set at 40 cm, and the center of the lower tip of the nose was positioned in the center of the screen.

[0057] (4) Analysis method The image analysis software "ImageJ" was used to analyze the captured images. Regarding the height of the outer corner of the eye (h (mm)), the distance from the outer corner of the eye to the intersection of a vertical line drawn from the outer corner of the eye and a horizontal line passing through the lower tip of the nose was calculated from the image captured after wearing each face pack (see Figure 10). Regarding the height of the corners of the mouth (m (mm), the distance from the intersection of a vertical line drawn upward from the corners of the mouth and a horizontal line passing through the lower tip of the nose was calculated (see Figure 10). Regarding the height of the outer corners of the eye (h) and the height of the corners of the mouth (m), the differences between the values ​​h1 and m1 obtained when using the face pack according to the Comparative Example and the values ​​h2 and m2 obtained when using the face pack according to the Example were calculated, and the change in the height of the outer corners of the eye (h2 - h1) and the change in the height of the corners of the mouth (m2 - m1) were examined.

[0058] (5) Test results According to the test results, as shown in Figure 11, the height h of the outer corner of the eye (h2) after wearing the face pack according to the example was 1.3 ± 0.4 mm higher than the value h1 after wearing the face pack according to the comparative example, and the height m of the corner of the mouth (m2) after wearing the face pack according to the example was 2.1 ± 1.0 mm higher than the value m1 after wearing the face pack according to the comparative example. From this, it can be seen that the incision 10 related to the frontalis muscle 8a contracts the frontalis muscle 8a to lift the entire eyebrow, thereby leading to an increase in the height of the outer corner of the eye. In this case, the incision 10 related to the orbicularis oculi muscle 8b promotes relaxation of the orbicularis oculi muscle 8b to suppress the formation of wrinkles at the outer corner of the eye, while this incision enhances (contracts) the effect of the frontalis muscle 8a, which acts in opposition to the orbicularis oculi muscle 8b, thereby helping to increase the height of the outer corner of the eye. Furthermore, with regard to the height of the corners of the mouth, it can be seen that the incisions 10 related to the zygomatic major muscle 8c and the laughing muscle 8d contract these muscles 8c, 8d, lifting the corners of the mouth. Figure 12 compares the results after wearing the face pack according to the example with the results after wearing the face pack according to the comparative example, using actual images of subject D shown in Figure 11. The photograph on the left was taken after wearing the face pack according to the comparative example, and the photograph on the right was taken after wearing the face pack according to the example.

[0059] Fig. 13 shows a second embodiment, and Fig. 14 shows a third embodiment. In these embodiments, the same components as those in the first embodiment are given the same reference numerals, and the description thereof will be omitted.

[0060] The second embodiment shown in FIG. 13 shows a face pack 21 in a stage preceding the face pack 1 according to the first embodiment. By using this face pack 21, the face pack 1 according to the first embodiment can be obtained. Specifically, incision marks 20 for forming incisions 10 are displayed on the surface of the face pack 21 (the surface of the sheet-like substrate 2). Naturally, these incision marks 20 extend in the direction of the assumed mimic muscles 8 in the corresponding regions. This allows the user to make incisions according to the incision marks 20 on the face pack 21 using a knife, cutter, or the like. Based on the selection of the incision, a face pack having incisions 10 that induce mimic muscle movement (contraction) based on a kinesthetic illusion using the Ruffini endings 13 can be easily obtained. In this case, the surface of the face pack 1 shown in FIG. 13 shows incisions 10 corresponding to the face pack 1 shown in FIG. 1. However, if many incision marks 20 corresponding to the various mimic muscles 8 are displayed in advance, the user's options will be broadened, and incisions 10 that suit the user's facial condition can be easily obtained.

[0061] The third embodiment shown in Figure 14 shows a face pack set 33 which is a precursor to the face pack 1 according to the first embodiment, and by using this face pack set 33, the face pack 1 according to the first embodiment can be obtained.

[0062] The face pack set 33 includes a face pack 31 and an incision guide sheet 32. The face pack 31 is the same as the face pack 1 according to the first embodiment described above, except that the incision 10 has been removed. When this face pack 31 is placed on the face, the openings 4 and 5 for the eyes and mouth and the incision 6 for the nose area in the face pack 31 position the face pack 31 in a predetermined state relative to the face, just like in the first embodiment.

[0063] A transparent or semi-transparent sheet is used for the incision guide sheet 32. This incision guide sheet 32 ​​has marks 34, 35, and 36 corresponding to the outline of the face pack 31, the openings 4 and 5 formed in the face pack 31, and the incisions 6, and also has incision marks 30 displayed in areas corresponding to various facial muscles 8 on the incision guide sheet 32, extending along the direction in which the expected facial muscles run in those areas. In this case, the incision marks 30 can be displayed in one or more corresponding areas, and one or more incision marks 30 can be displayed in one corresponding area.

[0064] As a result, by overlapping the incision guide sheet 32 ​​on the surface of an existing face pack 31 and aligning the incision guide sheets 34, 35, and 36 corresponding to the outline of the face pack 31, the eye and mouth openings 4 and 5, and the incision 6 for the nose area, the incision guide sheets 32 will align the incision guide sheets 30 on the incision guide sheet 32 ​​with the areas corresponding to the various facial muscles 8 on the face pack 31. Therefore, by making incisions according to the incision guide sheets 30 on the incision guide sheet 32 ​​in this state, the face pack 31 will have the incisions 10 and induce the movement (contraction) of the facial muscles based on a kinesthetic illusion using the Ruffini endings 13, while still utilizing its original function, i.e., it will be possible to obtain a face pack similar to the face pack 1 according to the first embodiment. Moreover, the incision guide sheets 30 can be selected according to the user's facial condition, allowing the user to train the facial muscles according to their own facial condition.

[0065] Although the embodiment has been described above, the present invention also includes the following aspects. (1) Use water as the liquid component. (2) The incision 10 is initially formed as a slit 17-like opening 10b of a fixed width. Of course, even in this case, it is preferable that the fixed width and length of the opening 10b work together to maintain the beauty serum filled state within the opening 10b based on the adhesive force of the beauty serum to the inner surface of the opening 10b. For example, it is preferable that the width of the opening 10b be 0.1 mm to 10 mm, and the length of the opening 10b in the extension direction be 5 mm to 30 mm. (3) After placing the sheet-like substrate 2 on the face, supply or replenish the beauty serum 3 or water using a water supply device such as a sprayer to the opening 10b of the slit 10. This allows the beauty serum 3 or water to be retained in an appropriate amount within the opening 10b, thereby generating the appropriate surface tension ST. (4) The sheet-like facial substrate is not limited to the entire face pack, but also includes divided face packs, such as face packs divided into upper and lower or left and right parts (parts, sets of parts combined), etc. [Industrial Applicability]

[0066] The present invention can be used to promote contraction or relaxation of the facial muscles to be improved, while ensuring ease of availability and ease of use that does not cause the user to feel burdened when using it. [Explanation of symbols]
