The open edge is formed by folding the sheet at least three times;
At least one of the open edges protrudes from the body;
The folding sheet relates to a folding sheet in which two of the open edges have a maximum width in a direction perpendicular to a longitudinal or horizontal center line of the sheet. INDUSTRIAL APPLICABILITY The present invention is useful because it is easy to deploy even when the sheet is wet and does not have a knob and can be applied to the skin, particularly the face.

Description

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

  A sheet formed of a base sheet such as a nonwoven sheet impregnated with a lotion or the like has been used for cosmetic treatment of the skin, particularly the face. Such sheets are usually available in the form of packages containing sheets folded in bags or sacks made from aluminum foil or the like.

  When using the sheet, the folded sheet is taken out of the package, unfolded, and attached to the skin.

  The folded sheet is so wet that it is often difficult to deploy the sheet using fingers. In particular, it may be difficult to find the edge of the folded sheet, and therefore it may take time to find the edge that the user should have. Furthermore, the wet edge can easily curl or bend, which can be difficult for the user to hold. Furthermore, wet sheets can be easily torn and must therefore be handled carefully. In addition, during the unfolding process, a portion of the spread sheet may naturally curl or bend in the air and adhere to another portion of the sheet. In that case, it is necessary to unfold the curled or bent part while holding the rest of the sheet, making it more difficult to apply the sheet to the skin.

  On the other hand, one or more knobs can be provided at the edge of the sheet. For example, U.S. Pat. No. 6,670,792 discloses a mask sheet having two tabs along the edge of the mask sheet so that the user can unfold the mask sheet with the tab. .

  However, such a knob requires a special design. Therefore, the presence of such a knob makes it difficult to manufacture the mask sheet. Furthermore, since the knob has only a small area, it is not sufficient to provide the knob in order to make the mask sheet easier to unfold.

FIG.

  After extensive research, the inventors have developed a folded wet sheet for cosmetic treatments easily without the aid of a knob by pre-folding the sheet in a special way and applying it to the skin. , Especially found that it is possible to paste on the face.

Therefore, the folding sheet of the present invention (hereinafter referred to as “folded sheet”) includes a main body and at least three open edges,
The open edge is formed by folding the sheet at least 3 times,
At least one of the open edges protrudes from the body,
Two of the open edges are characterized in that they have a maximum width in a direction perpendicular to the longitudinal or horizontal center line of the sheet.

  In one embodiment of the invention, the longitudinal or horizontal centerline can function as the longitudinal or horizontal axis of symmetry of the sheet. On the other hand, the longitudinal or horizontal center line may be separated from the longitudinal or horizontal symmetry axis of the sheet by, for example, 1 mm to 5 cm, preferably 3 mm to 3 cm, more preferably 5 mm to 1 cm. Alternatively, it may be parallel to the horizontal axis of symmetry or may not be parallel. Accordingly, the longitudinal or horizontal centerline may be a diagonal line with respect to the longitudinal or horizontal symmetry axis of the sheet.

  The “open edge” of the present invention means a part of the sheet, which is composed of a single layer of the sheet, and both surfaces of the layer are exposed to the outside. In the present invention, since the open edge is formed by folding the sheet, the open edge is different from a knob whose both surfaces are exposed to the outside without folding the sheet.

  In the present invention, the “main body” means a portion of the sheet other than the open edge. In general, the body consists of a plurality of layers of a sheet, at least one surface of which is covered with another layer of the sheet.

  Therefore, the open edge of the folded sheet of the present invention protrudes from the main body and generally protrudes from the outer periphery of the main body.

  The folded sheet of the present invention can be used for cosmetic treatments of the skin, such as applying moisture to or washing the skin, particularly the face.

  Therefore, the folded sheet of the present invention can be used as a face mask sheet, a neck mask sheet, a decollete mask sheet, or the like. It is also possible to use the folded sheet of the present invention as a wet tissue or wipe lingette. The folded sheet of the present invention is preferably used for a face including the entire face or a part of the face.

  Below, one Embodiment of the folded sheet | seat of this invention is described using figures.

  The folded sheets shown in FIGS. 1-5 correspond to one embodiment of the present invention designed to adhere to the face. Therefore, hereinafter, these sheets may be described as folded face mask sheets. However, as described above, the folded sheet of the present invention can be designed to be applied not only to the face but also to the body such as the neck or decollete.

  FIG. 1 shows a front view of an example of a folded face mask sheet of the present invention in a developed state. It should be understood that the folded sheet of the present invention should not be limited to this example.

  The face mask sheet shown in FIG. 1 is formed by a single substrate sheet 1, which comprises holes 2 and 2 for the eyes, a slit 3 for the nose and a hole 4 for the mouth. And slits 5 and 5 for cheeks. Any of the holes 2, 2, and 4 may be replaced with slits corresponding to the eyes and / or the mouth. On the other hand, the slit 3 may be replaced with a hole so that the nose can be seen. The base sheet 1 may have fewer or more slits than the above, depending on its size and shape. In view of the strength of the base sheet 1, it is preferable to limit the number of slits.

  The base sheet 1 can have one or more knobs, preferably on its contour (ie, the outer edge), to facilitate face mask sheet folding and unfolding operations. However, in the present invention, the presence of the knob is optional. Preferably, the base sheet 1 should not have a knob.

  A dotted line (C) in FIG. 1 corresponds to a longitudinal center line of the base sheet 1. The longitudinal centerline (C) shown in FIG. 1 defines the centerline of the substrate sheet 1 and is positioned to pass over the slit 3 for the nose as well as the hole 4 for the mouth. A longitudinal center line (C) shown in FIG. 1 functions as a longitudinal axis of symmetry of the base sheet 1. However, the longitudinal center line (C) is not necessarily on the symmetry axis of the base sheet 1. Therefore, the longitudinal center line (C) may be away from the longitudinal symmetry axis of the sheet, and may or may not be parallel to the longitudinal symmetry axis of the sheet.

  The face mask sheet shown in FIG. 1 has a first fold line (a) and a second fold line (b) represented by two dotted lines, the first fold line (a) and the second fold line (b). The face mask sheet can be folded along the second fold line (b). These two fold lines (a, b) are parallel to the longitudinal center line (C). As shown in FIG. 1, in this example, the fold lines (a, b) are positioned to pass over the holes 2, 2 for the eyes. However, neither the first fold line (a) nor the second fold line (b) need necessarily be positioned to pass over the eye hole (2, 2).

  According to the example shown in FIG. 1, the two fold lines (a, b) are parallel to each other, and the width between the two fold lines (a, b) is equal to the first fold line (a). The maximum width between the left outline of the base sheet 1 and the maximum width between the second fold line (b) and the right outline of the base sheet 1 are smaller.

  In FIG. 1, the distances from the longitudinal center line (C) to the first fold line and the second fold line (a, b) are constant. However, the above distances need not be the same. In other words, the width between the longitudinal center line (C) and the first fold line (a) and the width between the longitudinal center line (C) and the second fold line (b) are May be different. Therefore, the former may be longer than the latter, and the latter may be longer than the former.

  The face mask sheet shown in FIG. 1 can be folded as follows.

  As shown in FIG. 1, the base sheet 1 is folded once along the first fold line (a). Therefore, the base sheet 1 is folded as shown in FIG. The base sheet 1 shown in FIG. 2 is in the first folded state.

  Next, the base sheet 1 in the first folded state is further folded along the second folding line (b). In the example shown in FIGS. 1 and 2, the folding direction with respect to the first folding line (a) is different from the folding direction with respect to the second folding line (b). In other words, the left side of the base sheet 1 is folded forward along the first fold line (a), and the right side of the base sheet 1 is folded back along the second fold line (b). Therefore, the base sheet 1 is folded as shown in FIG. The cross section of the folded base sheet 1 is Z-shaped as shown in FIG. The base sheet 1 shown in FIG. 3 is in the second folded state.

  As shown in FIG. 3, the base sheet 1 in the second folded state is defined by the outline of the base sheet 1 and the first fold line (a) and the second fold line (b), respectively. It has two open edges 1a, 1b. The width of the open edges 1a, 1b is not limited, but the maximum width of each of the open edges 1a, 1b along the direction perpendicular to the first fold line (a) or the second fold line (b) is 0.1 to 50 mm, preferably 1 to 30 mm, more preferably 5 to 15 mm.

  Next, the base sheet 1 in the second folded state shown in FIG. 3 is further folded along the third fold line (c). Therefore, the base sheet 1 is folded as shown in FIG. The third fold line (c) is not parallel to the first fold line (a) or the second fold line (b). The third fold line (c) may not be perpendicular to the first fold line (a) or the second fold line (b). However, the third fold line (c) is preferably perpendicular to the first fold line (a) or the second fold line (b). The base sheet 1 shown in FIG. 4 is in the third folded state.

  As shown in FIG. 4, the folded base sheet 1 in the third folded state has three open edges 1a, 1b, and 1c. The open edge 1c is defined by the outline of the base sheet 1 and both the first fold line (a) and the second fold line (b). The length of the open edge 1c along the longitudinal center line (C) not shown in FIG. 3 is not limited, but the maximum length of the open edge 1c is 0.1-50 mm, preferably 1-30 mm, more preferably It can be 5-15 mm.

  The base sheet 1 shown in FIG. 4 is folded three times, so the folded face mask sheet shown in FIG. 4 can be used as a folded sheet for the cosmetic treatment according to the present invention. .

  In the folded face mask sheet shown in FIG. 4, the main body of the sheet is a part other than the three open edges 1a, 1b, 1c. The body of the sheet can consist of two or more layers of sheets, preferably four or more layers.

  Finally, the base sheet 1 in the third folded state can be further folded along the fourth fold line (d). In the example shown in FIGS. 3 and 4, the folding direction with respect to the third folding line (c) is different from the folding direction with respect to the fourth folding line (d). In other words, the lower side of the base sheet 1 is folded forward along the third fold line (c), and the upper side of the base sheet 1 is folded rearward along the fourth fold line (d). Therefore, the base sheet 1 is folded as shown in FIG. FIG. 5 (a) and FIG. 5 (b) show a front view and a rear view of the folded base sheet 1, respectively. The cross-section of the folded base sheet 1 is Z-shaped as shown in FIG. The base sheet 1 shown in FIG. 5 is in the fourth folded state.

  The third fold line (c) and the fourth fold line (d) are parallel to each other, but not parallel to the first fold line (a) or the second fold line (b). The third fold line (c) and the fourth fold line (d) may not be perpendicular to the first fold line (a) or the second fold line (b). However, the third fold line (c) and the fourth fold line (d) are preferably perpendicular to the first fold line (a) or the second fold line (b).

  As shown in FIG. 5, the folded base sheet 1 in the fourth folded state has four open edges 1a, 1b, 1c, and 1d. The open edge 1d is defined by the outline of the base sheet 1 and both the first fold line (a) and the second fold line (b). The length of the open edge 1d along the longitudinal center line (C) not shown in FIG. 5 is not limited, but the maximum length of the open edge 1d is 0.1-50 mm, preferably 1-30 mm, more preferably It can be 5-15 mm.

  The base sheet 1 shown in FIG. 5 is folded four times and can therefore be used as a folded sheet for cosmetic treatment according to the present invention.

  In the folded face mask sheet shown in FIG. 5, the main body of the sheet is a part other than the four open edges 1a, 1b, 1c, and 1d. The body of the sheet can consist of two or more layers of the sheet, preferably 7, 8, or 9 layers of the sheet.

  The folded base sheet 1 shown in FIG. 5 is more preferable than the folded base sheet 1 shown in FIG. This is because the size of the folded sheet 1 is reduced by the fourth folding. Furthermore, the size of the main body becomes smaller, and therefore the stickiness of the folded sheet is reduced, so that the unfolding of the sheet can be achieved more easily.

  As shown in FIG. 5, it is generally preferred that the sheet body has a square shape. The ratio of the square longitudinal line to the horizontal line is preferably 1: 1.1 to 1: 4, preferably 1: 1.2 to 1: 3, more preferably 1: 1.3 to 1: 2. Since the main body of the sheet has a square shape, for example, even when the user closes his eyes for water droplets immediately after washing the face, the user can easily recognize the open edge to be gripped.

  The folded face mask sheet shown in FIG. 5 can be unfolded by performing the reverse of the above.

  That is, the folded face mask sheet shown in FIG. 5 holds both the third open edge (1c) and the fourth open edge (1d), and the folded face mask sheet is in the longitudinal direction, i.e., FIG. Can be deployed by spreading along a longitudinal centerline (C) not shown in FIG. Therefore, the folded face mask sheet is in the state shown in FIG.

  Next, similarly, the folded face mask sheet shown in FIG. 3 holds both the first open edge (1a) and the second open edge (1b), and the folded face mask sheet is It can be unfolded by spreading in the lateral direction, ie along the third fold line (c) or the fourth fold line (d) shown in FIG.

  With the above-described unfolding process, the folded mask sheet can be unfolded at a higher speed.

  The example shown in FIGS. 1-5 of the folded sheet of the present invention has at least three open edges. Therefore, the user of the folded sheet can easily find the edge to be gripped.

  The open edge shown in FIGS. 1 to 5 has a shape with a relatively large area, part of which corresponds to the contour of the sheet, so that the design of the sheet is easier than a sheet with a knob on its contour It is. Further, since the open edge has a relatively large area than the knob, it is easier to grip the open edge. Moreover, when gripping the open edge with a finger, the gripping force from the finger cannot generally concentrate on the small area provided by the knob, and therefore the risk of breaking the sheet has the knob Reduced compared to sheet.

  The example shown in FIGS. 1-5 of the folded sheet of the present invention has a Z-shaped cross section, thus reducing the risk of breaking the sheet during the unfolding operation. In addition, the Z-shaped cross section reduces the main body of the sheet, so that the adhesive strength of the laminated sheet in the main body is reduced, and hence the sheet is more easily developed. This is enhanced when the folded sheet of the present invention has a Z-shaped cross-section in both the second and fourth folded states (this may be referred to as a “ZZ” fold). .

  Therefore, the present invention can provide a folded sheet that is easy to deploy and can be attached to the skin, particularly the face, even when the sheet is wet and does not have a knob.

  In another embodiment of the present invention, the sheet of the present invention may have a horizontal centerline instead of the longitudinal centerline (C) shown in FIG. In this embodiment, the horizontal centerline may or may not be on the horizontal symmetry axis of the sheet, and therefore the horizontal centerline may be away from the horizontal symmetry axis of the sheet and It may be parallel to the direction symmetry axis or may not be parallel. The first fold line and the second fold line may be parallel or substantially parallel to the horizontal centerline. The third fold line or the fourth fold line may not be parallel to the first fold line or the second fold line.

  The material of the folded sheet of the present invention is not limited, so any material can be used, for example, to make the base sheet 1 shown in FIGS. Two or more materials may be used.

  Generally, the materials are 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. It may be a woven or non-woven fabric made from Two or more selected from the above fibers may be used in combination.

  Alternatively, the materials can be synthetic polymers such as polyethylene and polyvinyl alcohol, semi-synthetic polymers such as biocellulose and alginate, and polysaccharides (e.g., carrageenan and xanthan gum), mucopolysaccharides (e.g., hyaluronic acid and sodium hyaluronate), polypeptides ( For example, it may be a film or sheet made from at least one selected from natural polymers such as γ-polyglutamic acid) and proteins (eg, gelatin and collagen). The film or sheet may be in the form of a gel or jelly, and this gel or jelly may be transparent, translucent, or opaque. Two or more selected from the above substances may be used in combination.

  The folded sheet of the present invention may be made from two or more layers. Thus, for example, the base sheet 1 shown in FIGS. 1-5 can be a laminated sheet comprising two or more stacked layers. When a laminated sheet is used, the material of each stacked layer may be the same or different from each other. For example, a laminated sheet can be made by laminating the above films or sheets made from synthetic, semi-synthetic, and / or natural polymers onto the woven or non-woven fabric.

  According to one embodiment of the present invention, for example, a thin plastic film can be bonded to a woven or non-woven fabric to form a sheet. In this embodiment, the thin plastic film makes it easier to unfold the folded sheet because the adhesion between the folded fabrics is reduced or impeded. Moreover, it is unnecessary to peel the thin plastic film from the cloth and therefore no waste is generated.

  The folded sheet of the present invention can comprise at least one cosmetic ingredient. Preferably, the folded sheet of the present invention comprises cosmetics, preferably liquid cosmetics such as lotions or emulsions. Therefore, the mask sheet of the present invention is preferably wet.

Aluminum foil, particularly laminated aluminum foil, is more preferred as a bag or sack material. Therefore, the present invention relates to a package including a folded mask sheet.

  The following examples illustrate the invention in more detail, but these examples should not be construed as limiting the scope of the invention.

[Example 1 and Comparative Examples 1-6]
(Example 1)
The folded mask sheet of the present invention that was folded as shown in FIG. 5 was used.

(Comparative Example 1)
A folded mask sheet, folded as shown in FIG. 6, was used. The size and material of the mask sheet were the same as the size and material of the mask sheet of Example 1.

(Comparative Example 2)
A folded mask sheet, folded as shown in FIG. 7, was used. The size and material of the mask sheet were the same as the size and material of the mask sheet of Example 1.

(Comparative Example 3)
A folded mask sheet, folded as shown in FIG. 8, was used. The size and material of the mask sheet were the same as the size and material of the mask sheet of Example 1. The folded mask sheet shown in FIG. 8 had one open edge.

(Comparative Example 4)
A folded mask sheet, folded as shown in FIG. 9, was used. The folded mask sheet shown in FIG. 9 had two knobs.

(Comparative Example 5)
A mask sheet having a thin plastic film 6 on the surface of the mask sheet shown in FIG. 10 was used. The mask sheet was folded as shown in FIG. 3 of Japanese Patent Laid-Open No. 2000-287751.

(Comparative Example 6)
A mask sheet was used that was wound and can be spread as shown in FIG. The size and material of the mask sheet were the same as the size and material of the mask sheet of Example 1.

(Evaluation)
Each of the folded mask sheets of Example 1 as well as the folded or rolled mask sheets of Comparative Examples 1-6, together with a cosmetic lotion, was placed in a small bag made from laminated aluminum foil.

  The bag material used and the composition of the cosmetic lotion used were the same in Example 1 and Comparative Examples 1-6.

  After a predetermined amount of time has passed, the mask sheet is removed from the bag and unfolded with fingers, and two professional examiners use the score system shown below to “ “Ease of deployment” and “lotion penetration” were evaluated, as well as “existence of waste”. In “existence of waste”, “Yes” means that some waste has occurred during the deployment operation, and “No” means that no waste has occurred during the deployment operation. The results are shown in Table 1.

  As shown in Table 1, the folded mask sheet of Example 1 was very easy to find because the edges were easy to find and the mask sheet was easy to unfold.

  On the other hand, as shown in Table 1, it was difficult to find the edges of the mask sheets of Comparative Examples 1 to 6. Therefore, the development of the mask sheets of Comparative Examples 1 to 6 was more difficult than the development of the mask sheet of Example 1.

  Since the mask sheet of Comparative Example 3 has one open edge, it may be superior in handling as compared with Comparative Example 1, Comparative Example 2, Comparative Example 5, and Comparative Example 6. However, the handleability of the mask sheet of Comparative Example 3 is still inferior to the handleability of the mask sheet of Example 1. Furthermore, when the mask sheet of Comparative Example 3 is folded, the open edge cannot be found any more, and therefore the mask sheet of Comparative Example 3 cannot be further folded.

  Similarly, since the mask sheet of Comparative Example 4 has two knobs, it may be better handled than Comparative Example 1, Comparative Example 2, Comparative Example 5, and Comparative Example 6. However, the handleability of the mask sheet of Comparative Example 4 is still inferior to the handleability of the mask sheet of Example 1. Furthermore, the mask sheet of Comparative Example 4 has a risk of being easily broken because the gripping force provided by the fingers is concentrated on a relatively small area of the knob. It was therefore necessary to handle it more carefully.

  Furthermore, it was found that the cosmetic lotion was difficult to penetrate the mask sheets of Comparative Examples 5 and 6.

  Moreover, it should be noted that, in use of the mask sheet, the mask sheet of Comparative Example 5 produced waste, i.e. a plastic film, to be disposed of, whereas the mask sheet of Example 1 did not produce such waste. .
