For face masks which cover the entire face, when applied to the user's face, it is preferable that the face mask comes into contact with the entire face without any peeling off of the user's face. In this regard, while conventional face masks have been devised to include cut notches so that a face mask formed from a planar sheet can be brought into as much contact as possible with the face, contact is not easily obtained as facial surface shape varies for each individual person.

In view of the above, the present invention provides a face mask that can easily be brought into close contact with individually variant shapes of facial surfaces.

SUMMARY OF THE INVENTION

The first invention is a face mask for cosmetic use formed by molding a base material sheet, the face mask being configured to cover the entire face of a user, and including a non-linear cut in a portion which comes into contact with the bottom region of a concave portion of the facial surface of the user and a non-linear cut in a portion which comes into contact with the apex region of a convex portion of the facial surface of the user.

The surface of the human face has convex and concave portions. The inventor of the present invention focused on the fact that the bottom region of the concave portion of the facial surface and the apex region of the convex portion have a larger degree of three-dimensional shape (greater convexity and concavity) compared to other portions. By providing a face mask with a configuration in which the degree of freedom of shape deformation is large in the portions of the face mask which come into contact with the bottom region of the concave portion and the apex region of the convex portion of the facial surface, it was found that the face mask could more easily be brought into close contact with the facial surface of the user than conventionally. The configuration for this is the aforementioned non-linear cut. While a straight line cut has a direction of deformation in one direction, since a non-linear cut has at least two directions, it has a plurality of directions to be deformed. It can thereby more easily be brought into close contact with facial surfaces which are of various shapes different for each person.

The second invention is a face mask for cosmetic use formed by molding a base material sheet, the face mask being configured to cover the entire face of a user, and including a nose portion cut for forming a nose portion which comes into contact with the nose of the user, and a side portion cut for forming a curved surface portion which comes into contact with a portion extending from a front surface to a side surface of the face of the user, the nose portion cut having a root portion cut which is cut obliquely downward from a side of the face mask toward a center direction and a central portion cut which is cut continuous with the root portion cut obliquely downward from the center direction toward a side direction; the side portion cut including a first portion which is cut from the outside of the face mask toward the center direction and a second portion which is cut continuous with the first portion obliquely downward at an angle different from that of the first portion.

According to the configuration of the second invention, in the nose portion cut, the root portion goes toward the center direction, whereas the center portion goes toward the side. As a result, the boundary between the root portion and the center portion is thinner than either the root portion or the center portion, so it easily deforms in accordance with the shape of the user's nose. In addition, since the nose portion cut is configured nonlinearly, it easily deforms in two directions. Further, in the side portion cut, the first portion is directed toward the center, whereas the second portion is directed obliquely downward. Therefore, the first portion can easily conform to protruding roundness in the vertical direction (the direction parallel to the direction from the forehead to the mouth) of the user's face, and the second portion can easily conform to protruding roundness in the substantially right and left direction (the direction parallel to the direction connecting both eyes) of the face. It is thereby possible to easily adhere to various facial shapes which differ for each person.

The third invention is a face mask with the configuration of the second invention, in which both end portions of a straight line shaped cut, which are lower end portions of the center portion of the nose portion cut, extend toward the side of the face mask beyond the end point of where the nose portion cut is cut obliquely downward.

According to the configuration of the third invention, the vicinities of the left and right end portions of the lower end portion cut makes it easy to conform to protruding roundness around the user's nose.

The fourth invention is a face mask with the configuration of the second invention in which the upper portion of the side portion cut forms a forehead corresponding portion which covers the forehead of the user, a lower portion of the side portion cut forms a lower facial surface corresponding portion which covers the lower portion of the facial surface of the user, and the lower facial surface corresponding portion extends toward the side of the face mask beyond the contact point of the forehead corresponding portion and the lower facial surface corresponding portion.

According to the configuration of the fourth invention, it is easy to grasp the left and right end portions of the lower facial surface corresponding portion and easily overlap it onto the forehead corresponding portion so that the face mask can conform to protruding roundness in the facial surface of the user.

The fifth invention is the face mask with the configuration of the second invention having a jaw portion which comes into contact with the jaw of the user, the jaw portion including a plurality of contiguous convex portions, and is configured in a manner such that the plurality of convex portions come into contact with the jaw of the user as a single unit.

According to the configuration of the fifth invention, since the plurality of convex portions are come together as a single unit at the user's jaw, it is possible to provide treatment to the jaw in a state where there are few overlapping portions in the face mask.

The sixth invention is the face mask with the configuration of the second invention having a jaw portion which comes into contact with the jaw of the user.

According to the configuration of the sixth invention, it is possible to provide treatment to the user's jaw.

The seventh invention is the face mask with the configuration of the second invention, in which the central portion cut of the nose portion cut has a starting point in the middle portion of the root portion cut.

According to the configuration of the seventh invention, the left and right regions in the root portion easily conform to the shape of the user's nose.

The eighth invention is the face mask with the configuration of the second invention, in which the side portion cut is a curved line shape.

According to the configuration of the eighth invention, since the direction of the side portion cut is in a curved line shape, it can more flexibly conform to protruding roundness in the user's face.

The ninth invention is the face mask with the configuration of the second invention having eyelid portions which cover the eyelids of the user, in which a lower portion of the eyelid portions is continuous with the main body of the face mask, an upper portion of the eyelid portions are cut in an arc shape, a plurality of cuts are formed radially continuous with the cut of the arc shape, and the eyelid portions are configured to allow use as either a closed portion or a folded portion.

According to the configuration of the ninth invention, the eyelid portions can provide treatment to the eyelid of the user as a closed portion and can also provide treatment to the portion below the eyelid as a folded portion.

The tenth invention is the face mask with the configuration of the second invention having a mouth opening corresponding to the mouth of the user, and end portion cuts which are cut from both end portions of the mouth opening toward the sides of the face mask.

According to the configuration of the tenth invention, the end portion cuts make it possible to conform to the shape of the mouth, and further makes it possible to conform even when the user is opening and closing their mouth for conversation or the like.

The eleventh invention is the face mask with the configuration of the second invention, in which a straight line shaped cut having both end portions bent substantially upward is formed in a portion corresponding to the mouth of the user.

According to the configuration of the eleventh invention, it is possible to provide treatment including to the lips of the user, and since both end portions of the mouth peripheral portion are bent substantially upward prior to application to the facial surface of the user, an image like that of someone smiling is expressed and can cause the user to relax.

The twelfth invention is the face mask with the configuration of the second invention, in which pigment or dye containing a cosmetic enhancing substance that promotes a cosmetic effect is printed on the front surface side in at least one of the following portions: the portion which comes into contact with the eyelids of the user, the portion which comes into contact with the area around the mouth of the user, and the portion which comes into contact with the facial surface peripheral region (face line) of the user.

According to the configuration of the twelfth invention, at least one portion of the user's face can be provided treatment even more effectively than other portions.

The present invention provides a face mask that can easily be brought into close contact with individually variant shapes of facial surfaces.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

First Embodiment

Preferred embodiments of the present invention will be described below with reference to the drawings. It should be noted that the description of configurations that can be appropriately implemented by those skilled in the art will be omitted and only the basic configuration of the present invention will be described.

As illustrated in FIG. 1, a face mask 1A is formed of a base material sheet 2. The base material sheet 2 is formed of, for example, a nonwoven fabric. The nonwoven fabric may be a material such as cupra, rayon, polyethylene, or polyvinyl alcohol. The base material sheet 2 is impregnated with a cosmetic composition. A main component of the cosmetic composition is water and further contains at least one of the following cosmetic ingredients: human oligopeptide-1, human oligopeptide-13, acetyl hexapeptide-8, palmitoyl pentapeptide-4, water-soluble collagen, hydrolyzed collagen, succinoyl atelocollagen, Magnesium ascorbyl phosphate, Saccharomyces (Sugar, placenta extract) fermented solution, sodium hyaluronate, sodium acetylated hyaluronate, sodium hyaluronate crosspolymer, cerebroside, arbutin, magnesium aspartate, potassium glycyrrhetinate, copper gluconate, zinc gluconate, placenta extract, saitai extract, water-soluble proteoglycan, platinum, sake cake extract, iwa-benkei root extract, apple fruit cultured cell extract, vitamin A oil, tocopherol, Saccharomyces cerevisiae extract, cerebroside, sodium pyrrolidone carboxylic acid (PCA), natto gum, avocado oil, caninabara fruit oil, apricot kernel oil, sunflower seed oil, dilauroyl glutamate sodium lysine, aminocaproic acid, or betaine.

In FIG. 1, the surface of the page facing toward the reader is the front side 1Aa of FIG. 2; the reverse side of the page is the back side 1Ab of FIG. 2. The back side 1Ab comes into contact with the facial surface of the user. The face mask 1A is configured so as to cover the entire face of the user.

On the base material sheet 2, there are formed eyelid portions 4A and 4B, a nose portion 6, a mouth opening 8, a jaw portion 14, side portion cuts 16A and 16B, and a protruding portion 18 indicating upper/lower, left/right, and front/back directionality of the face mask 1A. In the present specification, the direction in which the protruding portion 18 is formed is referred to as upper (upward); the direction in which the jaw portion 14 is formed is referred to as lower (downward); the directions in which the side portion cuts 16A and 16B are cut as viewed from the nose portion 6 are referred to as outside (sideward); and the direction from the outside toward the nose portion 6 is referred to as the center direction. In addition, the portion in which no cuts or openings are formed is referred to as the “main body portion” of the base material sheet 2.

The surface of the human face is three-dimensionally shaped with convex and concave portions. The shapes of the convex and concave portions are different depending on the facial region. The inventor of the present invention focused on the fact that the bottom region of the concave portion of the facial surface and the apex region of the convex portion are more three-dimensional in shape than the other portions with greater convexity and concavity. For example, as illustrated in FIG. 3, in the facial surface of the user 200A, the cheek bone proximate region 212 is an example of an apex region of a convex portion; the attachment base proximate region 220 which is the attachment base of the nose 204A below the eye 202A is an example of the bottom region of a concave portion; and the sub-alar region 224 which is the region between the ala 222 and the mouth 206 is also an example of the bottom region of a concave portion. The face mask 1A has a non-linear cut in the portion which comes into contact with the bottom region of the concave portion of the facial surface of the user 200A and, moreover, this is formed a non-linear cut in the portion which comes into contact with the vicinity of the apex of the convex portion of the facial surface. This makes it possible for it to easily come into contact with various facial surface shapes which differ for each individual person.

Generally, since a face mask is impregnated with a cosmetic composition, it adheres to the facial surface of the user. When applying a face mask, it is first placed so as to be in contact with the forehead, eyes and nose, and then adjusted according to the shape of the face such as cheeks, mouth and jaw. A face mask is made larger than the average human facial surface. When a face mask of a planar shape is fit to a three-dimensional face shape, a wrinkle or sagging portion forms in the face mask, and from that portion the face mask may peel off or lift away from the facial surface. In order to cope with problems of peeling and lifting, it is necessary to finely adjust the application of the face mask. In order to fine-tune the face mask, it is necessary to shift the already adhered face mask so as to slide on the face, or to grasp a portion of the face mask, remove it, and shift it. In this regard, the face mask 1A is made so that as it is applied to the face it can be easily adjusted after initial placement thereby facilitating effective application by preventing the development of wrinkles or sagging portions through effective cuttings and shapes.

Each area of configuration of the face mask 1A will be described in detail below.

<Configuration in the Vicinity of the Eyelids>

As described above, in the base material sheet 2, there are formed eyelid portions 4A and 4B for covering the user's eyelids (see FIG. 1). The eyelid portion 4A is continuous with the base material sheet 2 at the straight linear portion 4Aa. In addition, while in use the eyelid portion 4A is detached from the main body portion of the base material sheet 2 via a substantially arc-shaped eyelid portion cut 4Ab. Cuts 4Ac, 4Ad and 4Ae are formed radially continuous with the eyelid portion cut 4Ab. The eyelid portion 4A can cover the entire eyelid of the user as a closed portion (see FIG. 5), or it may be folded in the vicinity of the straight linear portion 4Aa and used as a folded portion (see FIGS. 6 and 7). It is configured to fold up at the edge of the eye in accordance with the user's eye size so as to intensively provide treatment to the portion below the user's lower eyelid.

Further, when the face mask 1A is applied to the facial surface of the user, the side edges of the cuts 4Ac, 4Ad and 4Ae overlap, or the cuts 4Ac, 4Ad and 4Ae open at an angle, thereby deforming in accordance with the shape of the eye of the user. The cuts 4Ac, 4Ad, and 4Ae follow a non-uniform slope from the protuberance around the eye of the user (the convex portion of the portion corresponding to the nose bone and the eyebrow) to the bottom of the concave portion such as the inner corner of the eye and the eye recess of the eyelid (see FIGS. 5, 6 and 7). If the cuts 4Ac, 4Ad and 4Ae did not exist, while the face mask would be in contact with the convex portion corresponding to the nose and the eyebrow, in the concave portion of the inner corner of the eye and eyelid portion corresponding to the eye hole portion surrounded by the convex portion of the nose and the eyebrow, the face mask would end up lifting thereby not allowing it to come into contact and fit the shape of the area in the vicinity of the user's eye. Because of the cuts 4Ac, 4Ad and 4Ae, the areas around the cuts 4Ac, 4Ad and 4Ae become independent and more easily conform to the convexities and concavities around the eye.

As described above, if applied as a shuttered portion with the eyelid portion 4A closed, the entire eyelid of the user can be provided treatment with the cosmetic composition (see FIG. 5). Since the configuration of the eyelid portion 4B is the same as that of the eyelid portion 4A, the description thereof will be omitted.

<Configuration in the Vicinity of the Nose>

In the base material sheet 2, a nose portion cut 102 is configured to form a nose portion 6 which comes into contact with the user's nose. As illustrated in FIG. 8, the nose portion 6 includes a root portion 6a, a center portion 6b, and a tip portion 6c. The nose portion cut 102 is configured non-linearly in the region which comes into contact with the vicinity of the bottom portion of concave shapes on the facial surface of a user 200A or the like.

In other words, the nose portion cut 102 includes root portion cuts 102Aa and 102Ba which are cut obliquely downward from the outer direction of the face mask 1A toward the center direction (direction toward the center axis Z1 direction of the nose portion 6); central portion cuts 102Ab and 102Bb which are cut continuous with root portion cuts 102Aa and 102Ba, respectively, in an obliquely downward direction from the center direction to the side; tip portion cuts 102Ac and 102Bc which are cut continuous with central portion cuts 102Ab and 102Bb, respectively, in a direction obliquely downward from the outer direction toward the center direction while drawing a curve; and a linear cut 102d which is cut continuous with tip portion cuts 102Ac and 102Bc. Both end portions of the linear cut 102d extend sideward on both sides of a line segment connecting the lower end of the tip portion cut 102Ac and the lower end of the tip portion cut 102Bc. The portions which extend sideward are referred to as the extension portions.

Through the above-described configuration, portions S1A, S1B, S2A and S2B of the nose portion cut 102 are formed nonlinearly. The portion S1A is a portion that comes into contact with the attachment base proximate region 220 (see FIG. 3), and the portion S2A is a portion that comes into contact with the sub-alar region 224 (see FIG. 3).

As illustrated in FIGS. 8 and 9, through the above-described configuration of the nose portion 6, an imaginary line L1 which is a boundary with the main body portion of the face mask 1A; an imaginary line L2 which is a boundary between the root portion 6a and the center portion 6b and; an imaginary line L3 which is a boundary between the center portion 6b and the tip portion 6c are formed. An imaginary line L4A extending from the intersection point P1A of the root portion cut 102Aa and the central portion cut 102Ab to the linear cut 102d and an imaginary line L4B extending from the intersection point P1B of the root portion cut 102Ba and central portion cut 102Bb to the linear cut 102d are formed. The imaginary lines L4A and L4B have different inclination angles with respect to the central axis Z1 as indicated by arrows X1 and X2, for example, in accordance with the shape of a user's nose.

As the face mask 1A is applied to the face of a user and the nose portion 6 comes into contact with the user's nose, as illustrated in FIG. 9, the nose portion 6 rises from the surface of the page toward the reader at the imaginary line L1 while in the state of being connected to the main body portion of the base material sheet 2. At this time, the outer portion 6Ab outside of the imaginary line L4A is bent toward the direction of the back side of the page in a shape corresponding to the shape of the user's nose. Likewise, the outer portion 6Bb outside of the imaginary line L4B is bent toward the direction of the back side of the page in a shape corresponding to the shape the user's nose.

People have various shapes of facial surface. If we focus our attention on a person's nose, for example, the height h1 of the nose 204A of the user 200A illustrated in FIG. 3 is taller than the height h2 of the nose 204B of the user 200B illustrated in FIG. 4. As illustrated in FIG. 6, as the face mask 1A is applied to the face of the user 200A, the nose portion 6 deforms in accordance with the shape of the nose 204A of the user 200A to come into close contact with the nose 204A. The nose portion 6 readily deforms in accordance with the shape of the nose 204A via the imaginary lines L1, L2, L3, L4A and L4B (see FIGS. 8 and 9). Similarly, as illustrated in FIG. 7, as the face mask 1A is applied to the face of the user 200B, the nose portion 6 deforms in accordance with the shape of the nose 204B of the user 200B to come into close contact with the nose 204B.

FIGS. 10 and 11 are schematic views of the nose 204A of the user 200A and the nose 204B of the user 200B, respectively, as viewed from the side surface direction. Although there are various shapes of noses, the nose portion 6 easily deforms in accordance with the shape of any nose via the imaginary lines L1, L2, L3, L4A and L4B (see FIGS. 8 and 9). For example, when the nose 204A has a relatively tall height h1 as illustrated in FIG. 10, the nose portion 6 is easily deformed in accordance with the shape of the nose 204A via the virtual lines L1, etc. When the nose 204B has a relatively short height h2 as illustrated in FIG. 11, the nose portion 6 is easily deformed in accordance with the shape of the nose 204B via the imaginary lines L1, etc.

Further, as illustrated in FIGS. 10 and 11, by having the root portion cut 102Aa (102Ba) at the imaginary line L2, since it further facilitates the deforming and increases the degree of freedom from the main body portion, it is even easier for it to conform to the nose 204A as the face mask 1A is applied and the nose portion 6 rises.

As illustrated in FIG. 9, nose peripheral portions 6Ad and 6Bd are formed in the main body of the face mask 1A by the protruding portions of the linear cut 102d, and as the face mask 1A is applied to the user's face, the nose peripheral portions 6Ad and 6Bd deform independent of the main body portion of the face mask 1A in accordance with concavities and convexities in the curved surface of the portions peripheral to the user's nose (nasal ala). As a result, the face mask 1A can be brought into close contact with the sub-alar region 224 (see FIG. 3) without lifting from the facial surface of the user, and the portions peripheral of the user's nasal ala can be provided treatment with the cosmetic composition.

The portion of the face to which the root portion cut 102Aa (see FIGS. 8 and 9) comes into contact with is the attachment base proximate region 220 of the eye (see FIG. 3). The root portion cut 102Aa includes a side edge portion 102Aau on the nose portion 6 side and a side edge portion 102Aas on the main body side. As the face mask 1A is applied, the planar-shape of the face mask 1A is brought into close contact with protrusions which are the convex portions of the nose 204A and the cheekbone 212a in a manner whereby it is pulled by the respective protrusions. At this time, due to the existence of the side edge portion 102Aau on the nose portion 6 side and the side edge portion 102Aas on the main body side of the root portion cut 102Aa, it comes into close contact in accordance with the convex and concave shape of the attachment base proximate region 220.

The user grasps the side edge portion 102Aas (see FIG. 12 A) and raises it obliquely upward toward the center so as to turn about the end point 102Aac of the root portion cut 102Aa, and in FIG. 12 B as illustrated, and shifts it so as to overlap (hereinafter referred to as “overlapping”) with the side edge portion 102Aau. As a result, the gap formed between the main body portion and the nose portion 6 is reduced, and the face mask 1A can be brought into close contact with the facial surface without any wrinkling or sagging. By not having the root portion cut 102Aa (102Ba) and the central portion cut 102Ab (102Bb) continuous in a straight line but disposed at a predetermined angle θ1, it becomes possible to effectively perform the above-mentioned overlapping. The predetermined angle θ1 may be, for example, at least 90 degrees and no greater than 130 degrees. If the root portion cut 102Aa (102Ba) and the central portion cut 102Ab (102Bb) were to form a straight line, it would become necessary for the user to grasp the linear portion and shift it parallel to the center direction (Z1 direction in FIG. 8) which is a difficult operation; further, since the force of it being shifted would be applied to the entire side portion by central portion cut 102Ab (102Bb), it would end up causing the side portion to also shift toward the center direction making it easy for wrinkles to form in the face mask, and after being shifted it would become necessary to make fine adjustment by once again adjusting the side portion, and any readjustment of the side portion would make it necessary to then readjust the vicinity of the nose portion as well.

<Configuration of the Mouth>

In the base material sheet 2, there is formed a mouth opening 8 corresponding to the mouth portion of the user (see FIG. 1). At both ends of the mouth opening 8 are formed end cuts 8a and 8b. The end cuts 8a and 8b make it easy for it to conform to the shape of the mouth which is different for each person. As illustrated in FIG. 13, when the face mask 1A is lifted upward from the lower side so as to overlap the cut lower sides 8as and 8bs onto the cut upper sides 8au and 8bu of the end cuts 8a and 8b, the mouth opening 8 can be made smaller to fit the shape of the user's mouth and bring the face mask 1A into close contact nearer to the edge of the lips. In other words, the end cuts 8a and 8b function as means for adjusting the size of the mouth opening 8. Further, by having the end cuts 8a and 8b, the degree of freedom to deform the mouth opening 8 is increased so that even when the mouth is moved while wearing the face mask 1A, the state in which the face mask 1A is inclose contact can be maintained.

<Configuration of the Jaw Portion>

In the base material sheet 2 is formed a convex jaw portion 14 (see FIG. 1) which comes into contact with the user's jaw. The jaw portion 14 includes contiguous convex portions 14a, 14b, 14c and 14d. FIG. 14 is a view of the state in which the face mask 1A is applied to the user 200A (see FIG. 6) as seen from below. The jaw portion 14 is applied so as to be foldable along the jaw of the user 200A. At that time, the convex portions 14a, etc. come together as they approach the lower jaw so as to come into close contact with the jaw 230 of the user 200A as a single unit. Through the convex portions 14a, etc., as the face mask 1A is applied, any extra base material sheet 2 doubles up around the periphery of the jaw and makes it possible for the face mask 1A to be brought into close contact without any lifting.

<Configuration of the Sides>

In the base material sheet 2 are formed side portion cuts 16A and 16B (see FIG. 1). The side portion cut 16A is formed in a non-linear fashion. In other words, the side portion cut 16A includes a first portion 16A1 which is cut from the outside of the face mask 1A toward the center thereof; and a second portion 16A2 which is continuous with the first portion 16A1 and cut obliquely downward at an angle different from that of the first portion 16A1. The first portion 16A1 extends in a straight line from the outside of the face mask 1A toward the center. The second portion 16A2 extends obliquely downward toward the center. The side portion cut 16B is formed in a line symmetrical to the side portion cut 16A relative to the central axis Z1 (see FIG. 8) of the nose portion 6. Since the side portion cuts 16A and 16B are formed in a nonlinear fashion, as the face mask 1A is applied to the user's face, the face mask 1A forms into a curved surface portion to conform with the swell in the peripheral region having the cheek bone 121a as its apex and the shape of the following portion (see FIG. 6).

Above the side portion cut 16A is a forehead corresponding portion 10A which covers the user's forehead, and below the side portion cut 16A is a lower facial surface corresponding portion 12A which covers the lower portion of the user's facial surface. The lower facial surface corresponding portion 12A extends further toward the side of the face mask 1A than a contact point with the forehead corresponding portion 10A. Similarly, above the side portion cut 16B is a forehead corresponding portion 10B which covers the user's forehead, and below the side portion cut 16B is a lower facial surface corresponding portion 12B which covers the lower portion of the user's facial surface. The lower facial surface corresponding portion 12B extends further toward the side of the face mask 1A than the contact point with the forehead corresponding portion 10B. The forehead corresponding portions 10A and 10B are formed in such a size and shape so as not to come into contact with hair in the hairline at the side portion of the facial surface when the face mask 1A is applied to the facial surface of the user.

FIG. 15 is a schematic diagram showing the vicinity of the side portion cut 16A of the face mask 1A. When applying the face mask 1A, the upper end proximate portion 16Ad1 of the lower facial surface corresponding portion 12A is gripped so as to overlap the lower end proximate portion 16Au1 of the forehead corresponding portion 10A to adjust the face mask 1A so it fits the shape of the facial surface. Here, since the upper end proximate portion 12Aa illustrated in FIG. 1 protrudes sideward beyond the contact point of the lower facial surface corresponding portion 12A and the forehead corresponding portion 10A, it is easy to grasp, easy to lift, and it is possible to comfortably perform the above-mentioned adjustment. By making it so as to overlap onto the lower end proximate portion 10Aa of the forehead corresponding portion 10A, as the face mask 1A is adjusted so as to fit the shape of the facial surface, as illustrated in FIGS. 6 and 7, it becomes the shape along the face line (the line from the cheek to the jaw) of the face of the users 200A and 200B, and further, the shape of the forehead corresponding portion 10A and the lower facial surface corresponding portion 12A is formed into the shape whereby it does not come into contact with the side hairline 210. Since it does not come into contact with the side hairline 210, the face mask 1A does not lift away from the facial surface because of coming into contact with the side hairline 210, nor does it peel away from portions that have come into contact with the hairline at the side portions, it is possible to effectively perform beauty treatment with the cosmetic composition. The same applies to the forehead corresponding portion 10B and the lower facial surface corresponding portion 12B.

FIG. 16 is a schematic view showing the vicinity of the side portion cut 302A of a conventional face mask 300 and is not an embodiment of the present invention. With a face mask 300 of the conventional example illustrated in FIG. 16, the side portion cut 302A has a simple linear shape. If one tries to overlap the forehead corresponding portion 310A with the lower facial surface corresponding portion 312A by rotating it centered about an end point Py1, it is necessary to pull up the entire lower portion of the face mask from the straight line connecting the end points Py2 and Py1 which adds significant drag force. Such drag force is also transmitted beyond the end point Py1 to the region Q1 which lies toward the center, and as a result, it also pulls the region Q1 upward at angle causing wrinkles to form in the region Q1. Furthermore, when the force dragging up the lower facial surface corresponding portion 312A is transmitted to portions which come into contact with the mouth opening or under the nose where there are many facial surface convexities and concavities and the degree of adhesion is relatively low, those portions are also pulled in the direction of region Q1, and this makes it necessary to correct the wrinkles in the region Q1 as well as correct the shifted mouth opening or portions under the nose by returning them to their predetermined positions. Even if the user grips the lower facial surface corresponding portion 312A and lifts little by little centered about the end point Py1 with a small force, small hill-like wrinkles will end up forming at the end point Py1.

Meanwhile, with the face mask 1A, as illustrated in FIG. 15, since the side portion cut 16A has the first portion 16A1 and the second portion 16A2 (see FIG. 1), it is possible to pivot centered about the end point Px1 when overlapping the forehead corresponding portion 10A with the lower facial surface corresponding portion 12A. With the face mask 1A, the side portion cut 16A rotates centered about the end point Px1 so that the drag force with which the face line proximate region 12Ab (see FIG. 6) is pulled obliquely upward toward the center is cut off by the second portion 16A2 without extending toward the center. In other words, since movement of the face line proximate region 12Ab does not influence the portion lying further toward the center, no wrinkles develop in the portion lying further toward the center.

In addition, since the side portion cut 16A has the first portion 16A1 and the second portion 16A2, as illustrated in FIG. 15, the angle with which the forehead corresponding portion 10A is overlapped with the lower facial surface corresponding portion 12A differs in the region S1 from that in the region S2. In the region S1, the first portion 16Ad1 on the lower facial surface corresponding portion 12A side is brought to overlap the first portion 1 6Au1 on the forehead corresponding portion 10A side while changing its position so as to be raised upward from a horizontal angle (the direction of 9 o'clock on a clock face). Meanwhile, in the region S2, the second portion 16Ad2 on the lower facial surface corresponding portion 12A side is brought to overlap the second portion 16Au2 on the forehead corresponding portion 10A side while changing its position so as to be raised upward from an angle sloping downward toward the center.

Convexities and concavities of a person's face are not convexities and concavities directed in a single direction but convexities and concavities directed in a plurality of directions. By configuring so that the overlapping angles of the forehead corresponding portion 10A and the lower facial surface corresponding portion 12A are different, the face mask 1A deforms more easily in accordance with the shape of the user's face. In this instance, since the side portion cut 16A pivots centered about the end point Px1, the intersection point Px2 between the first portion 16A1 and the second portion 16A2 moves toward the center of the face mask 1A. In other words, the first portion 16A1 rotates while moving toward the center. Therefore, the end point Px3 outside the first portion 1 6Ad1 of the lower facial surface corresponding portion 12 moves more toward the center of the face mask 1A in comparison with the conventional example illustrated in FIG. 16. As a result, more roundness can be formed with the planar-shaped face mask 1A in comparison with the conventional example. Due to the rotation described above, the lower facial surface corresponding portion 12A and the forehead corresponding portion 10A are configured so as to be integrated into a shape that conforms to the face line without being in contact with the side portion hairline of the user. On the contrary, if the side portion cut 302A has a simple straight line as with the face mask 300 of the conventional example in FIG. 16, since the angle at which the forehead corresponding portion 310A and the lower facial surface corresponding portion 312A overlap will be uniform, it will be unable to follow the convexities and concavities of an actual face of a person, locations will develop which are unable to be brought into close contact with facial surface, and it will end up lifting up from there. In addition, since the side portion cut 302Ad simply attempts to pivot about the end point Py1, the effect of not being in contact with the user's side portion hairline is not sufficient.

Second Embodiment

A second embodiment will be described with reference to FIGS. 17 and 18. Descriptions of items common to the first embodiment are omitted.

As illustrated in FIG. 17, with the face mask 1B, a linear mouth portion cut 30 in which both end portions are bent substantially upward is formed in a portion corresponding to the user's mouth. The mouth portion cut 30 includes a straight line portion 30c and bent portions 30a and 30b, which are formed at each end of the straight line portion 30c. The bent portions 30a and 30b are bent substantially upward. By making the mouth portion a slit, the face mask 1B is brought into close contact with the user's facial surface without any gaps forming in the region where laugh lines appear on both sides of the mouth and below the nose.

As illustrated in FIG. 18, as the face mask 1B is applied to the facial surface of the user 200A, the upper portion 32 of the mouth portion cut 30 covers the upper lip of the user 200A, and the lower portion 34 covers the lower lip of the user 200A to allow the upper and lower lips to also be provided treatment with the cosmetic composition. Further, the bent portions 30b cover the side portions of both ends of the lip of the user 200A in such a manner as to make a facial expression that resembles smiling. In addition, since both ends of the mouth portion cut 30 are bent portions 30a and 30b, they are brought into close contact with the shape of the upper lip more closely than if only a straight line cut, and moreover, while wearing the face mask 1B, the mouth can be opened and moved effortlessly.

Third Embodiment

A third embodiment will be described with reference to FIGS. 19 to 21. Descriptions of items common to the first embodiment are omitted.

As illustrated in FIG. 19, side portion cuts 16A and 16B of the face mask 1C are curved. The first portion 16Aa is a curve extending obliquely slightly upward from the outside of the face mask 1C toward the center. The second portion 16Ab is a curve extending obliquely slightly downward and toward the center of the face mask 1C. The side portion cut 16B is formed symmetric to the side portion cut 16A relative to the center axis Z1 (see FIG. 3).

The face mask 1C has a jaw portion 14 which comes into contact with the user's jaw. The jaw portion 14 comes into contact with the jaw of the user 200A. The jaw portion 14 projects substantially downward in the base material sheet 2. The jaw portion 14 is defined by the cuts 20A and 20B from the main body portion of the base material sheet 2 and are made so as to easily fit the shape of the user's jaw.

As illustrated in FIG. 20, as the face mask 1C is applied to the face of the user 200A, it easily conforms to the shape of the face of the user 200A or 200B through the curved side portion cuts 16A and 16B. Also, as illustrated in FIGS. 20 and 21, the jaw portion 14 comes into contact with the jaw 230 of the user 200A or 200B but does not touch the neck 240.

Fourth Embodiment

A fourth embodiment will be described with reference to FIGS. 22 to 24. Descriptions of items common to the third embodiment are omitted.

As illustrated in FIGS. 22 and 24, a central portion cut 102Ab of the face mask 1D has a starting point in the middle of the root portion cut 102Aa. In addition, the central portion cut 102Bb has a starting point in a middle portion of the root portion cut 102Ba.

As illustrated in FIG. 24, as the face mask 1D is applied to the face of the user 200A, the side portion 6a of the nose portion 6 easily folds at the imaginary line L4A and easily conforms to the shape of the nose of the user 200A.

Fifth Embodiment

A fifth embodiment will be described with reference to FIGS. 25 to 27. Descriptions of items common to the first embodiment are omitted.

On the face mask 1A, there are provided portions 50A and 50B (see FIG. 25) which come into contact with the eyelid of the user, portions 52A and 52B (see FIG. 26) which come into contact with the periphery of the mouth of the user, and portions 54A and 54B (see FIG. 27) which come into contact with the peripheral areas of the facial surface (face line) of the user. On the front surface side of at least one contacting portion, a pattern is printed with a pigment containing a cosmetic enhancing substance for promoting a cosmetic effect. The cosmetic enhancing substance may be a substance having a blood circulation promotion or relaxation effect, for example, garnet powder. The portion on which the pattern is printed is a portion on the face of the user which is particularly requiring of cosmetic treatment. A pattern may be printed in areas such as the temporal muscle, near the eyes where sagginess or wrinkles may be noticeable, in portions where laugh lines can easily develop, near the mouth where wrinkles may be noticeable, cheeks where sagginess may become noticeable, or the forehead, and is not limited to the portions illustrated in FIGS. 25 to 27. A pattern maybe printed with a dye containing a cosmetic enhancing substance that promotes a cosmetic effect differing from the present embodiment.

It should be noted that the face mask of the present invention is not limited to the above embodiments; various modifications can be made within the scope not departing from the gist of the present invention.
