The present invention relates to a folded mask sheet which is preferably used for cosmetic treatments of the skin, in particular the face.

BACKGROUND ART

A mask sheet which is formed by a substrate sheet . such as a non- woven fabric sheet impregnated with a lotion or the like has been used for cosmetic treatments of the skin, in particular the face.

For example, USP 6702792 discloses a mask sheet which is used for moisturizing the skin of the face, and removing dirt from the skin

A mask sheet is usually marketed in a package containing the mask sheet which has been folded in a bag or sack made of aluminum foil or the like.

When using a mask sheet, the mask sheet is taken from the bag or sack of the package, is unfolded in the air to spread the mask sheet, and is applied onto the skin.

Since the folded mask sheet is very wet, it is often difficult to unfold the mask sheet using the fingers in mid-air. In addition, when the folded mask sheet is spread in mid-air, a part of the lotion or the like which has been impregnated in the mask sheet may drip off.

Further, during the unfolding process, a part of the spread mask sheet may spontaneously bend in the air to attach another part of the mask sheet. If so, the application of the mask sheet onto the skin becomes more difficult because unfolding the bending part is . necessary while holding the rest of the mask sheet. Furthermore, applying the folded mask sheet onto the appropriate position on the skin, in particular the face requires a mirror, in order to make sure that the eyes and mouth are not covered with the mask sheet .

DISCLOSURE OF INVENTION

BEST MODE FOR CARRYING OUT THE INVENTION

After diligent research, the inventors have discovered that it is possible to easily unfold a folded wet mask sheet and apply it onto the skin, in particular the face, even without a mirror, by folding the mask sheet beforehand in a specific manner, and by unfolding the folded wet mask sheet on the skin.

Thus, the folded mask sheet according to the present invention is characterized in that it has at least one crease, the folded mask sheet has an external surface comprising an area surrounded by said crease (s) or by said crease (s) and the outline of the mask sheet, the area is configured to be firstly brought into contact with the skin, and the area comprises at least a part of a

longitudinal center line of the mask sheet.

It is preferable that the above area is not covered by any part of the mask sheet. Thus, it is preferable that the external surface of the mask sheet other than the above area is folded in the same direction, in particular to the back side of the above area.

Hereinafter, the folded mask sheet according to the present invention is explained by using figures. The folded mask sheets shown in Figures 1 to 8 are designed to be attached onto the face. Therefore, they may be described hereafter as folded face mask sheets. However, the folded mask sheet according to the present invention can be designed to be applied onto not only the face but also the body such as the neck or the decollete.

Fig. 1 shows a front view of an example of a folded face mask sheet according to the present invention in the unfolded position. Fig. 2 shows a front view (Figure 2(a)) and a back view (Figure 2(b)) of the example shown in Figure 1 in the folded position. The face mask sheet shown in Figures 1 and 2 is formed by a single substrate sheet (1) having holes (2,2) for the eyes, a hole (3) for the nose, and a hole (4) for the mouth. Any of the holes (2,2,3,4) may be replaced with slit(s) to uncover the eyes, nose and/or mouth. The substrate sheet (1) may have a tab or tabs, preferably on the outline thereof, for facilitating the folding and unfolding operations.

The dotted and dashed line (C) in Figures 1 and 2 corresponds to a longitudinal center line of the substrate sheet (1) . The

longitudinal center line (C) shown in Figures 1 and 2 defines a center line of the substrate sheet (1) and is positioned to pass over the hole (3) for the nose as well as the hole (4) for the mouth. The longitudinal center line (C) shown in Figures 1 and 2 functions as a longitudinal symmetric axis for the substrate sheet (1) -

The face mask sheet shown in Figures 1 and 2 has two creases (5,6) represented by two dotted lines along which the face mask sheet can be folded. The two creases (5,6) are parallel with the longitudinal center line (C) . As clearly shown in Figure 1, in this example, the creases (5,6) are positioned to pass over the holes (2,2) for the eyes.

Thus, the external surface of the substrate sheet (1) is divided into three areas. The first area (la) is surrounded by the creases (5,6) and the outlines of the substrate sheet (1). The first area (la) is configured to be firstly attached to the face. The second area (lb) is surrounded by the crease (5) and the outline of the substrate sheet (1). The third area (lc) is surrounded by the crease (6) and the outline of the substrate sheet (1) .

As shown in Figures 1 and 2, the first area (la) comprises a longitudinal center line (C) . Therefore, the longitudinal center line (C) cannot be any of the creases (5,6) . Thus, the

longitudinal center line (C) is not folded along itself.

In Figures 1 and 2, the second and third areas (lb,lc) are the same size. However, the second and third areas (lb,lc) do not need to be the same size. Thus, the distance between the crease (5) from the longitudinal center line (C) and that between the crease (6) from the longitudinal center line (C) may be different from each other. Furthermore, the creases (5,6) do not

necessarily have to be positioned to pass over the holes (2,2) for the eyes.

The face mask sheet shown in Figure 1 is folded along the creases (5,6) to form the folded face mask sheet according to the present invention shown in Figure 2. In this example shown in Figures 1 and 2, the crease (5) is firstly folded, and next the crease (6) is folded. However, it is possible for the crease (6) to be folded first, and for the crease (5) to be folded next. In any event, the second area (lb) and the third area (lc) are bent to the back of the first area (la) such that the first area (la) is exposed and covered by nothing.

The folded face mask sheet shown in Figure 2 can be applied onto the face as follows.

First, the first area (la) of the folded face mask sheet shown in Figure 2 is attached to the face while positioning the holes (2,2), the hole (3) and the hole (4) on the eyes, nose, and mouth,

respectively. The above positioning operation is easy such that it is not necessary to use a mirror.

Second, the crease (6) is unfolded to apply the third area (lc) onto the face.

Third, the crease (5) is unfolded to apply the second area (lb) onto the face.

If the crease (6) had firstly been folded, the crease (5) would be unfolded to apply the second area (lb) onto the face, and then, the crease (6) would be unfolded to apply the third area (lc) onto the face.

Accordingly, the folded face mask sheet is unfolded on the face as shown in Figure 1. Since the folded face mask sheet is unfolded on the face, with the first area (la) being fixed on the face, the unfolding operation is easy even if the folded face mask sheet is wet. As the folded face mask sheet is not spread in the air, no part of the spread face mask sheet will spontaneously bend over and attach to another part of the face mask sheet.

Consequently, the folded face mask sheet according to the present invention shown in Figure 2 is easy to unfold and can be applied onto the skin of the face even without a mirror.

Fig. 3 shows a front view of another example of a folded face mask sheet according to the present invention in the unfolded position. Fig. 4 shows a front view (Figure 4(a)) and a back view (Figure 4(b)) of the example shown in Figure 3 in the folded position.

The face mask sheet shown in Figures 3 and 4 is also formed by a single substrate sheet (1) having holes (2,2) for the eyes, a hole (3) for the nose, and a hole (4) for the mouth. Any of the holes (2,2,3,4) may be replaced with slit(s) to uncover the eyes, nose and/or mouth. The substrate sheet (1) may have a tab or tabs, preferably on the outline thereof, for facilitating the folding and unfolding operations.

The dotted and dashed line (C) in Figures 3 and 4 corresponds to a longitudinal center line of the substrate sheet (1) . The

longitudinal center line (C) shown in Figures 3 and 4 defines a center line of the substrate sheet (1) and is positioned to pass over the hole (3) for the nose as well as the hole (4) for the mouth. The longitudinal center line (C) shown in Figures 3 and 4 functions as a longitudinal symmetric axis for the substrate sheet (1) .

The face mask sheet shown in Figures 3 and 4 has two creases (5,6) represented by two dotted lines along which the face mask sheet can be folded. The two creases (5,6) are perpendicular to the longitudinal center line (C) . As clearly shown in Figure 3, the crease (5) is positioned to pass over the holes (2,2) for the eyes, while the crease (6) is positioned to pass over the hole (4) for the mouth. Thus, the external surface of the substrate sheet (1) is divided into three areas. The first area (la) is surrounded by the creases. (5,6) and the outlines of the substrate sheet (1). The first area (la) is configured to be firstly attached to the face. The second area (lb) is surrounded by the crease (5) and the outline of the substrate sheet (1). The third area (lc) is surrounded by the crease (6) and the outline of the substrate sheet (1) .

As shown in Figures 3 and 4, each of the first area (la) , the second area (lb) and the third area (lc) comprises a part of the longitudinal center line (C) . Therefore, the longitudinal center line (C) cannot be any of the creases (5,6). Thus, the

longitudinal center line (C) is not folded along itself.

In Figures 3 and 4, the second and third areas (lb,lc) are almost the same size. However, the second and third areas (lb,lc) do not need to be the same size. Thus, the relative position of the crease (5) and that of the crease (6) along the longitudinal center line (C) may be different from each other. Therefore, the crease (5) does not necessarily have to be positioned to pass over the holes (2,2) for the eyes. Likewise, the crease (6) does not necessarily have to be positioned to pass over the hole (4) for the mouth.

The face mask sheet shown in Figure 3 is folded along the creases (5,6) to form the folded face mask sheet according to the present invention shown in Figure 4. In this example shown in Figures 3 and 4, the crease (6) is folded first, and the crease (5) is folded next. However, it is possible for the crease (5) to be folded first, and for the crease (6) to be folded next. In any event, the second area (lb) and the third area (lc) are bent to the back of the first area (la) such that the first area (la) is exposed and covered by nothing.

The folded face mask sheet shown in Figure 4 can be applied onto the face as follows. First, the first area (la) of the folded face mask sheet shown in Figure 4 is attached to the face while positioning the holes (2,2), the hole (3) and the hole (4) on the eyes, nose, and mouth,

respectively. The above positioning operation is easy such that it is not necessary to use a mirror.

Second, the crease (5) is unfolded to apply the second area (lb) onto the face .

Third, the crease (6) is unfolded to apply the third area (lc) onto the face.

If the crease (5) had firstly been folded, the crease (6) would be unfolded to apply the third area (lc) on to the face, and then, the crease (5) would be unfolded to apply the second area (lb) onto the face.

Accordingly, the folded face mask sheet is unfolded on the face as shown in Figure 3.

Since the folded face mask sheet is unfolded on the face, with the first area (la) being fixed on the face, the unfolding operation is easy even if the folded face mask sheet is wet. As the folded face mask sheet is not spread in the air, no part of the spread face mask sheet will spontaneously bend over and attach to another part of the face mask sheet.

Consequently, the folded face mask sheet according to the present invention shown in Figure 4 is easy to unfold and can be applied onto the skin of the face even without a mirror.

Fig. 5 shows a front view of another example of a folded face mask sheet according to the present invention in the unfolded position. Fig. 6 shows a front view (Figure 6(a)) and a back view (Figure 6(b)) of the example shown in Figure 5 in the folded position.

The face mask sheet shown in Figures 5 and 6 is also formed by a single substrate sheet (1) having holes (2,2) for the eyes, a hole

(3) for the nose, and a hole (4) for the mouth. Any of the holes

(2,2,3,4) may be replaced with slit(s) to uncover the eyes, nose and/or mouth. The substrate sheet (1) may have a tab or tabs, preferably on the outline thereof, for facilitating the folding and unfolding operations.

The dotted and dashed line (C) in Figures 5 and 6 corresponds to a longitudinal center line of the substrate sheet (1). The

longitudinal center line (C) shown in Figures 5 and 6 defines a center line of the substrate sheet (1) and is positioned to pass over the hole (3) for the nose as well as the hole (4) for the mouth. The longitudinal center line (C) shown in Figures 5 and 6 functions as a longitudinal symmetric axis for the substrate sheet (1) -

The face mask sheet shown in Figures 5 and 6 has four creases (5,6,7,8) represented by four dotted lines along which the face mask sheet can be folded. Two of the creases (5,6) are parallel to the longitudinal center line (C) and the other two creases (7,8) are perpendicular to the longitudinal center line (C) . As clearly shown in Figure 5, the crease (7) is positioned to pass over the holes (2,2) for the eyes, while the crease (8) is

positioned to pass over the hole (4) for the mouth. In this example shown in Figures 5 and 6, the creases (5,6) do not pass over the holes (2,2) for the eyes. However, any of the creases (5,6) may be positioned to pass over the holes (2,2) for the eyes as in the example shown in Figures 1 and 2.

Thus, the external surface of the substrate sheet (1) is divided into five areas by the creases (5,6,7,8). The first area (la) is surrounded by the creases (5,6,7,8). The first area (la) is configured to be attached to the face first. The second area (la') is surrounded by the crease (7) and the outline of the substrate sheet (1). The third area (la") is surrounded by the crease (8) and the outline of the substrate sheet (1). The fourth area (lb) is surrounded by the creases (5,7,8) and the outline of the substrate sheet (1) . The fifth area (lc) is surrounded by the creases (6,7,8) and the outline of the substrate sheet (1).

As shown in Figures 5 and 6, each of the first area (la), the second area (la') and the third area (la") comprises a part of the longitudinal center line (C) . Therefore, the longitudinal center line (C) cannot be any of the creases (5,6,7,8). Thus, the longitudinal center line (C) is not folded along itself.

In Figures 5 and 6, the fourth and fifth areas (lb,lc) are the same size. However, the fourth and fifth areas (lb,lc) do not need to be the same size. Thus, the distance between the crease

(5) from the longitudinal center line (C) and that between the crease (6) from the longitudinal center line (C) may be different from each other. Furthermore, the relative position of the crease

(7) and that of the crease (8) along the longitudinal center line

(C) may be different from each other. Therefore, the crease (7) does not necessarily have to be positioned to pass over the holes

(2,2) for the eyes. Likewise, the crease (8) does not necessarily have to be positioned to pass over the hole (4) for the mouth.

The face mask sheet shown in Figure 5 can be folded first along the creases (7,8), and then along the creases (5,6) to form the folded face mask sheet as shown in Figure 6. However, it is possible that the creases (5,6) are firstly folded, and next the creases (7,8) are folded. In any event, the second area (la'), the third area (la"), the fourth area (lb), and the fifth area (lc) are bent to the back of the first area (la) such that the first area (la) is exposed and covered by nothing.

The folded face mask sheet shown in Figure 6 can be applied onto the face as shown in Figure 7.

First, as shown in Figure 7(a), the first area (la) of the folded face mask sheet shown in Figure 5 is attached to the face while positioning the holes (2,2), the hole (3) and the hole (4) on the eyes, nose, and mouth, respectively. The above positioning operation is easy such that it is not necessary to use a mirror.

Second, the crease (5) is unfolded as shown in Figure 7(b) to apply the fifth area (lb) onto the face.

Third, the crease (6) is unfolded as shown in Figure 7(c) to apply the fourth area (lc) onto the face. Fourth, the crease (7) is unfolded as shown in Figure 7(d) to apply the second area (la') onto the face.

Fifth, the crease (8) is unfolded as shown in Figure 7(e) to apply the third area (la") onto the face.

Since the folded face mask sheet is unfolded on the face, with the first area (la) being fixed on the face, the unfolding operation is easy even if the folded face mask sheet is wet. As the folded face mask sheet is not spread in the air, no part of the spread face mask sheet will spontaneously bend over and attach to another part of the face mask sheet.

Consequently, the folded face mask sheet according to the present invention shown in Figure 6 is easy to unfold and can be applied onto the skin of the face even without a mirror.

The face mask sheet according to the present invention may be made of two or more separate sheets. Figure 8 shows a front view of an example of a face mask sheet according to the present invention made of two separate sheets.

The face mask sheet shown in Figure 8 consists of an upper sheet

(9) to be applied around the eyes, nose and forehead, and a bottom sheet (10) to be applied around the mouth and cheeks. The upper sheet (9) has holes (2,2) for the eyes and a hole (3) for the nose. The bottom sheet (10) has a hole (4) for the mouth. Any of the holes (2,2,3,4) may be replaced with slit(s) to uncover the eyes, nose and/or mouth. The upper sheet (9) and/or the bottom sheet

(10) may have a tab or tabs, preferably on the outline thereof, for facilitating the folding and unfolding operations.

The dotted and dashed line (C) in Figure 8 corresponds to a

longitudinal center line of the substrate sheet (1). The

longitudinal center line (C) shown in Figure 8 defines a center line of the upper and bottom sheets (9,10) and is positioned to pass over the hole (3) for the nose as well as the hole (4) for the mouth. The longitudinal center line (C) shown in Figure 8 functions as a longitudinal symmetric axis for the upper and bottom sheets (9,10). The face mask sheet shown in Figure 8 has four creases (5,6,7,8) represented by four dotted lines along which the face mask sheet can be folded. Two of the creases (5,6) are parallel to the longitudinal center line (C) and the other two creases (7,8) are perpendicular to the longitudinal center line (C) . As clearly shown in Figure 8, the crease (7) is positioned to pass over the holes (2,2) for the eyes, while the crease (8) is positioned to pass over the hole (4) for the mouth. In the example shown in Figure 8, the creases (5,6) pass over the holes (2,2) for the eyes. However, any of the creases (5, 6) may be positioned not to pass over the hole (2,2) for the eyes. Likewise, any of the creases (7,8) may be positioned not to pass over the holes (2,2) for the eyes and the hole (4) for the mouth, respectively.

The face mask sheet shown in Figure 8 can be folded as the example shown in Figures 5 and 6. The folded face mask sheet shown in Figures 5 and 6 can be applied onto the face as shown in Figure 7. Alternatively, the upper sheet (9) may be first unfolded, and then the bottom sheet (10) may be unfolded, and vice versa.

Furthermore, either the upper sheet (9) or the bottom sheet (10) may be applied onto the face.

The face mask sheet consisting of two or more separate sheets according to the present invention can more suitably fit on the face, because the relative position between the upper sheet (9) and the bottom sheet (10) can be adjusted.

The examples of the face mask sheet according to the present invention shown in Figures 1 to 8 have a plurality of creases.

However, it is possible that the mask sheet according to the present invention may have only one crease. For example, in the examples shown in Figures 1 to 4, either of the creases (5,6) may not be necessary. The folded mask sheet according to the present invention which has a single crease is easy to unfold on the skin, since one unfolding operation is sufficient.

The material of the substrate sheet (1), the upper sheet (9) and the bottom sheet (10) is not limited, and therefore any material can be used for preparing these sheets. Two or more materials may be used.

Typically, the material may be a woven or non-woven fabric made of natural fibers such as cotton, pulp, bamboo and cellulose fibers, semi-natural fibers such as viscose rayon fibers and synthetic fibers such as polyester fibers, polyethylene terephthalate fibers, polyethylene fibers, and polypropylene fibers. Two or more

selected from the above fibers may be used in combination.

Alternatively, the material may be a film or sheet made from at least one selected from synthetic polymers such as polyethylenes and polyvinylalcohols, semi-synthetic polymers such as bio- celluloses and alginates, and natural polymers such as

polysaccharides (e.g., carageenan and xanthan gum),

mucopolysaccharides (e.g., hyaluronic acid and sodium hyaluronate) , polypeptides (e.g., γ-polyglutamic acid) and proteins (e.g., gelatin and collagen) . The film or sheet may be in the form of a gel or a jelly which may be transparent, translucent or opaque.

Two or more selected from the above substances may be used in combination .

The substrate sheet (1), the upper sheet (9) and the bottom sheet (10) may be a single sheet or a layered sheet comprising two or more stacked sheets. If a layered sheet is used, the material of each sheet stacked may be the same or different from each other. For example, the layered sheet may be prepared by laminating the above film or sheet made from a synthetic polymer, a semisynthetic polymer and/or a natural polymer on the above woven or non-woven fabric.

The mask sheet according to the present invention may comprise a cosmetic, preferably a liquid cosmetic such as a cosmetic water and a milky lotion. Thus, the mask sheet according to the present invention is preferably wet.
