[0003] [Patent Document 1] Japanese Patent Application Laid-Open No. 2016-151070 Summary of the Invention [Problem to be solved by the invention]

[0004] Skin care sheets are impregnated with a liquid such as a cosmetic lotion, and compared to dry sheets that are not impregnated with a liquid, the adhesive strength between the stacked sheets is strong, which can make them difficult to unfold during use. In particular, skin care sheets impregnated with a large amount of liquid are required to have a strong adhesive strength and be easy to unfold.

[0005] The present invention has been made in view of the above problems, and has as its object to improve the operability of a skin care sheet impregnated with a liquid when it is unfolded. [Means for solving the problem]

[0006] The skin care sheet according to one embodiment has a thickness of 45 g / m 2 More than 70g / m 2 A sheet layer having a basis weight of 400% by weight or more and 600% by weight or less is impregnated with a liquid, and the sheet layer is placed in a packaging bag in a folded state folded around a fold line. The fold line has an initial fold line that serves as an initial starting point for unfolding when the sheet layer is unfolded from the folded state. The sheet layer in the folded state has a horizontal direction along the initial fold line, a vertical direction perpendicular to the horizontal direction, and a first region and a second region arranged on either side of the initial fold line and stacked together. The first region has a first vertical edge that is an edge in the vertical direction and located opposite the initial fold line, and a first horizontal edge that is located on one side in the horizontal direction. The second region has a second vertical edge that is an edge in the vertical direction and located opposite the initial fold line, and a second horizontal edge that is located on the one side in the horizontal direction. The first vertical edge and the second vertical edge are offset in the vertical direction. The second lateral edge of the first lateral edge is offset in the lateral direction.

[0007] A sheet packaging body according to one embodiment includes a skin care sheet and a packaging bag for packaging the skin care sheet. The packaging bag has an opening area where an opening for inserting and removing the skin care sheet can be formed. The opening area is provided on one end side of the packaging body in the longitudinal direction. The first vertical edge and the second vertical edge of the skin care sheet are located on the opening area side. [Brief explanation of the drawings]

[0009] (1) Overview of the embodiment At least the following matters will become clear from the description of this specification and the accompanying drawings. The skin care sheet according to one embodiment has a thickness of 45 g / m 2 More than 70g / m 2 A sheet layer having a basis weight of 400% by weight or more and 600% by weight or less is impregnated with a liquid, and the sheet layer is placed in a packaging bag in a folded state folded around a fold line. The fold line has an initial fold line that serves as an initial starting point for unfolding when the sheet layer is unfolded from the folded state. The sheet layer in the folded state has a horizontal direction along the initial fold line, a vertical direction perpendicular to the horizontal direction, and a first region and a second region arranged on either side of the initial fold line and stacked together. The first region has a first vertical edge that is an edge in the vertical direction and located opposite the initial fold line, and a first horizontal edge that is located on one side in the horizontal direction. The second region has a second vertical edge that is an edge in the vertical direction and located opposite the initial fold line, and a second horizontal edge that is located on the one side in the horizontal direction. The first vertical edge and the second vertical edge are offset in the vertical direction. The second horizontal edge of the first horizontal edge is offset in the horizontal direction. According to this aspect, because the first vertical edge of the first region and the second vertical edge of the second region are offset in the vertical direction, a user can grasp the offset portion to easily peel the first region from the second region and unfold the sheet layer from the starting fold. Similarly, because the first horizontal edge of the first region and the second horizontal edge of the second region are offset in the horizontal direction, a user can grasp the offset portion to easily peel the first region from the second region and unfold the sheet layer from the starting fold. In a skin care sheet impregnated with a large amount of liquid (400% by weight or more and 600% by weight or less), even if the surface tension between the sheet layers becomes high, the sheet can be easily unfolded, improving operability during unfolding.

[0010] According to a preferred embodiment, the sheet layer has a surface extending in a planar direction and a back surface opposite the surface. At least one of the surface and the back surface has an uneven structure formed thereon. According to this embodiment, the uneven structure is formed on the surface or back surface of the sheet layer, or on both the surface and back surface of the sheet layer. The surface tension of the surface in contact with the uneven structure is reduced, thereby reducing resistance during deployment. This makes it easier for the user to deploy the sheet layer.

[0011] According to a preferred embodiment, the uneven structure is formed on at least one of a surface of the first region facing the second region and a surface of the second region facing the first region. According to this embodiment, when unfolding the sheet from the starting fold, the first region and the second region are easily peeled apart, allowing the sheet layer to be easily unfolded and improving operability during unfolding.

[0012] According to a preferred embodiment, the uneven structure is formed on only one of the front and back surfaces. The uneven surface tends to have a large surface area when it comes into contact with the skin, and applying the uneven surface to the skin can enhance the effect of applying liquid and wiping away dirt. In this case, since the uneven structure is disposed on only one surface, the user can sense by touch which surface has the uneven structure that should be applied to the skin.

[0013] According to a preferred embodiment, the recesses of the uneven structure are low-basis weight portions having a lower basis weight than the protrusions. According to this embodiment, portions with different basis weights are formed in the sheet layer, and thus shading is formed in the sheet layer due to the difference in basis weight. When dirt is wiped away with the skin care sheet, the dirt becomes more noticeable due to the shading of the surrounding area. Furthermore, the area where dirt has adhered to the sheet layer can be easily identified by the shading, and unused areas can be easily identified.

[0014] According to a preferred embodiment, the sheet layer in the folded state is folded around the starting fold as a base point and also around a vertical fold along the vertical direction as a base point. According to this embodiment, since the sheet layer is folded in the first region and the sheet layer is folded in the second region, the stacked sheet layers are likely to shift relative to each other, and the sheet layer has gripping portions formed in multiple regions, making it easier for the user to unfold the sheet layers.

[0015] According to a preferred embodiment, the vertical distance between the first vertical edge and the second vertical edge is 5 mm or more and 10 mm or less. According to this embodiment, since the distance between the first vertical edge and the second vertical edge is 5 mm or more, the misaligned portion of the sheet layer can be easily grasped with fingers. Furthermore, when impregnating the sheet layer with liquid, the liquid is generally supplied from the starting fold side of the folded sheet layer, and the liquid diffuses in the planar direction, thereby penetrating the entire folded sheet layer. If the distance between the first vertical edge and the second vertical edge is too long, the liquid may not penetrate the entire extended portion of the first region and the second region, resulting in uneven impregnation. However, since the distance between the first vertical edge and the second vertical edge is 10 mm or less, uneven impregnation of the liquid can be suppressed.

[0016] A sheet package according to one aspect includes a skin care sheet and a packaging bag that packages the skin care sheet. The packaging bag has an opening area where an opening can be formed to allow the skin care sheet to be inserted and removed. The opening area is located at one end of the packaging bag in the longitudinal direction. The first vertical edge and the second vertical edge of the skin care sheet are located on the opening area side. According to this aspect, when an opening is formed in the opening area, a user can insert a finger through the opening and grasp at least one of the first vertical edge and the second vertical edge to remove the sheet. Following this removal operation, the sheet layer can be easily unfolded.

[0017] (2) Overall Schematic Configuration of Skin Care Sheet and Sheet Package According to the Embodiment Hereinafter, a skin care sheet and a sheet packaging according to an embodiment will be described with reference to the drawings. In the following description of the drawings, identical or similar parts are designated by identical or similar reference numerals. However, it should be noted that the drawings are schematic, and the dimensional ratios and the like may differ from those of the actual product. Therefore, specific dimensions and the like should be determined with reference to the following description. Furthermore, the drawings may include parts with different dimensional relationships and ratios.

[0018] FIG. 1 is a perspective view of a sheet packaging body 100 according to an embodiment. FIG. 2 is a perspective view of a skin care sheet 1 according to an embodiment. FIG. 3 is a plan view of the skin care sheet 1. FIG. 4 is a cross-sectional view taken along line AA in FIG. 3, and FIG. 5 is a schematic view of an enlarged portion B in FIG. 4. The sheet packaging body 100 includes a skin care sheet 1 and a packaging bag 90 for packaging the skin care sheet 1. The packaging bag 90 may contain one or more skin care sheets 1. In this embodiment, one skin care sheet 1 is contained in the packaging bag 90. The skin care sheet 1 is sealed in the packaging bag 90 before use, thereby preventing deterioration before use.

[0019] The skin care sheet 1 is a sheet that is placed against the user's skin and may be a facial sheet or a body sheet. The skin care sheet 1 is a wet sheet impregnated with 400% to 600% by weight of liquid. The liquid may be anything that is applied to the body, such as a cleanser, moisturizer, lotion, alcohol, or disinfectant. In this embodiment, the sheet is a makeup wipe impregnated with a cleanser. The weight does not refer to the weight of the liquid inside the packaging bag 90, but rather to the weight of the liquid held in the skin care sheet 1. The weight % can be calculated using the following method. One skin care sheet 1 is removed from the packaging bag 90, and the weight of the entire skin care sheet 1 is measured. The weight of the skin care sheet 1 is designated A. Next, the skin care sheet 1 is dried until it is completely dry, and the weight of the skin care sheet alone after drying is measured. The weight of the skin care sheet is designated B. The weight % is calculated using (AB) / B. The absolute dry state is a state in which all the chemicals (including non-volatile components) have been dried and only the nonwoven fabric remains.

[0020] Skin care sheet 1 is 45g / m 2 More than 70g / m 2 The sheet layer 2 may be made of a substrate formed from a fibrous material in a sheet form (for example, nonwoven fabric, gauze, cotton sheet, tissue paper) having a basis weight of 45 g / m 2 More than 70g / m 2 A sheet layer 2 with the following basis weight is less likely to tear when placed against the skin, and is able to retain a constant amount of liquid, facilitating continuous application of the liquid to the skin. The sheet layer 2 is contained in a packaging bag 90 in a folded state, folded around creases. The skin care sheet 1 in a folded state is the skin care sheet when removed from the packaging bag 90, and is folded around one or more creases.

[0021] The fold has a start fold FL1 that serves as the starting point for initial unfolding when the sheet layer 2 is unfolded from its folded state. After removing the skin care sheet 1 from the packaging bag 90, the user may use it as is or unfold it. The start fold FL1 is the fold that serves as the starting point for initially unfolding the sheet layer 2; in other words, it is the fold in the final folding step when folding the sheet layer 2. As shown in FIG. 2 , the sheet layer 2 in its folded state has a transverse direction CD that runs along the start fold FL1 and a longitudinal direction LD that is perpendicular to the transverse direction CD. The transverse direction CD and the longitudinal direction LD extend in a planar direction and are perpendicular to each other. Note that, in the present invention, a configuration extending in a certain direction is a concept that includes not only a configuration parallel to that direction, but also a configuration that is at an angle of less than 15 degrees to that direction.

[0022] The folded sheet layer 2 has a first region 10 and a second region 20 stacked on each other and positioned across an initial fold line FL1. The first region 10 may have a first longitudinal edge 11 in the machine direction LD, located opposite the initial fold line FL1; a first starting edge 13 in the machine direction LD, located on the initial fold side; a first horizontal edge 12 on one side in the cross direction CD; and a first other edge 14 on the other side in the cross direction CD. The first region is an area surrounded by the first longitudinal edge 11, the first horizontal edge 12, the first starting edge 13, and the first other edge 14. The first longitudinal edge 11 and the first starting edge 13 extend in the cross direction CD. The first horizontal edge 12 and the first other edge 14 extend in the machine direction LD. The first starting edge 13 may coincide with the initial fold line FL1. The second region 20 may have a second vertical edge 21 that is an edge in the longitudinal direction LD and is located opposite the start fold line FL1, a second starting edge 23 that is an edge in the longitudinal direction LD and is located on the start fold side, a second horizontal edge 22 that is located on one side in the transverse direction CD, and a second other edge 24 that is located on the other side in the transverse direction CD. The second region 20 is an area surrounded by the second vertical edge 21, the second horizontal edge 22, the second starting edge 23, and the second other edge 24. The second vertical edge 21 and the second starting edge 23 extend in the transverse direction CD. The second horizontal edge 22 and the second other edge 24 extend in the longitudinal direction LD. The second starting edge 23 may coincide with the start fold line FL1.

[0023] The first vertical edge 11 and the second vertical edge 21 are offset in the longitudinal direction LD. That is, the length of the first region 10 in the longitudinal direction LD does not coincide with the length of the second region 20 in the longitudinal direction LD. Because the first vertical edge 11 of the first region 10 and the second vertical edge 21 of the second region 20 are offset in the longitudinal direction LD, a user can easily peel the first region 10 and the second region 20 by grasping the offset portions and unfold the sheet layer 2 from the start fold line FL1. Furthermore, the second horizontal edge 22 of the first horizontal edge 12 is offset in the transverse direction CD. A user can easily peel the first region 10 and the second region 20 by grasping the offset portions on the first and second horizontal edges and unfold the sheet layer 2 from the start fold line FL1. Preferably, the first other edge 14 and the second other edge 24 may also be offset in the transverse direction CD. By grasping the misaligned portions on the first other edge 14 and second other edge 24 sides, the user can easily peel the first region 10 and the second region 20 apart and unfold the sheet layer 2 from the starting fold FL2. When multiple sheet layers are stacked in the first region 10 and the second region 20, the edges are defined by the outermost edges of the stacked sheet layers. According to this embodiment, the skin care sheet 1 impregnated with a large amount of liquid (400% by weight or more and 600% by weight or less) can be easily unfolded even when the surface tension between the sheet layers 2 is high, improving operability during unfolding. Furthermore, because the sheet layer 2 can be easily unfolded, it can be folded and stored compactly.

[0024] The sheet layer 2 has a surface 81 extending in a planar direction and a back surface 82 opposite the surface 81. The surface 81 and the back surface 82 are surfaces of the sheet layer 2 in an unfolded state. At least one of the surface 81 and the back surface 82 may have an uneven structure 85. The uneven structure 85 refers to regularly formed unevenness, not irregular unevenness due to the presence or absence of fibers. The convex and concave portions constituting the uneven structure 85 have different thicknesses and can be formed by embossing or a low basis weight portion. According to this embodiment, the uneven structure 85 is formed on the surface 81 or the back surface 82 of the sheet layer 2, or on both the surface 81 and the back surface 82 of the sheet layer 2. The surface tension of the surface in contact with the uneven structure 85 is reduced, thereby reducing resistance during unfolding. This makes it easier for the user to unfold the sheet layer. The height of the uneven structure is not particularly limited. However, preferably, the difference in thickness between the recessed and protruding portions is 200 μm or more, and the difference in thickness between the recessed and protruding portions may be half or less of the thickness of the protruding portions, and the width of the protruding portions may be 2.0 mm or more.

[0025] Below, the time it took for a skin care sheet according to a comparative example that does not have a concave-convex structure and a skin care sheet according to an embodiment to be unfolded from a folded state was measured. The skin care sheet according to the comparative example and the skin care sheet according to the embodiment were folded in the same manner. Five testers unfolded each sheet three times and measured the time it took to unfold. The measurement results are shown in Table 1. As shown in Table 1, it was found that the unfolding time varied significantly depending on whether or not the sheet had a concave-convex structure. A skin care sheet with a concave-convex structure allows for smooth and quick unfolding. [Table 1]

[0026] 4, the uneven structure 85 is formed on at least one of the first opposing surface 15 that faces the second region 20 in the first region 10 and the second opposing surface 25 that faces the first region 10 in the second region 20. The uneven structure 85 of this embodiment is formed on both the first opposing surface 15 and the second opposing surface 25. According to this aspect, when unfolding from the starting fold FL1 as a base point, the first region 10 and the second region 20 are easily peeled off, allowing the sheet layer 2 to be easily unfolded and improving operability during unfolding.

[0027] The uneven structure 85 may be provided on at least one of the front back surface 6 (see FIG. 4 ) located on the reverse side of the front surface 5 located closest to the user of the sheet layer 2 and the first opposing surface 15. The applicant's investigation into various usage patterns revealed that, when opening the package along the starting fold FL1, many users grasp and unfold the sheet layer 2 with their index finger on the first opposing surface 15 and their thumb on the front surface 5, or with their thumb on the front surface 5 and their index finger on the front back surface 6 behind the front surface 5. When the sheet layer 2 is unfolded while being grasped in this manner, the surface on which the uneven structure 85 is formed comes into contact with the index finger and the opposite surface comes into contact with the thumb. Some users may unfold the sheet layer 2 and then fold it for use. In this case, users generally fold the sheet layer 2 with the surface where the thumb is located facing forward and the front surface facing inward. Therefore, in a folded state, the surface on which the uneven structure 85 is formed is disposed on the outer side of the sheet layer. The user can use the skin care sheet by unconsciously placing the surface on which the uneven structure 85 is formed against the skin. The surface having the uneven structure 85 tends to have a large surface area when it comes into contact with the skin due to the uneven structure 85, and placing the surface having the uneven structure against the skin can enhance the effect of applying liquid and wiping away dirt.

[0028] The uneven structure 85 may be formed on only one of the front surface 81 and the back surface 82 of the sheet layer 2. The surface having the uneven structure 85 tends to have a larger surface area when it comes into contact with the skin, and applying the surface having the uneven structure 85 to the skin can enhance the effect of applying liquid and wiping away dirt. In this case, because the uneven structure 85 is arranged on only one surface, the user can sense by touch which surface on which the uneven structure 85 is formed that should be applied to the skin.

[0029] The recesses of the uneven structure 85 may be low-basis weight portions with a lower basis weight than the protrusions. Since portions with different basis weights are formed in the sheet layer 2, shading is created in the sheet layer 2 due to the differences in basis weight. When dirt is wiped off with the skin care sheet 1, the dirt becomes more noticeable due to the shading of the surrounding area. Furthermore, the area where dirt has adhered to the sheet layer 2 can be easily identified by the shading, and the unused area can be easily identified.

[0030] The sheet layer 2 in the folded state may be folded around the start crease FL1 as a base point, and may also be folded around vertical creases FL11 and FL12 along the longitudinal direction as base points. In this embodiment, the sheet layer 2 is folded around multiple creases in addition to the start crease FL1. More specifically, the sheet layer 2 is folded from the unfolded state around the first vertical crease FL11 and the second vertical crease FL12 extending in the longitudinal direction LD as base points, and then folded around the start crease FL1 as a base point. Thus, the sheet layer 2 in the folded state is stacked into six layers. With this configuration, the sheet layer 2 is folded in the first region 10 and in the second region 20, which makes it easier for the stacked sheet layers to shift relative to each other. This allows the sheet layer 2 to have gripping portions formed in multiple regions, making it easier for the user to unfold the sheet layer 2. In addition, since the sheet layer 2 is folded in both the longitudinal direction LD and the transverse direction CD, it can be stored compactly.

[0031] When the skin care sheet 1 of this embodiment is folded about the first vertical fold FL11 and the second vertical fold FL12, the three layers have approximately the same length in the horizontal direction CD. However, preferably, the length in the horizontal direction CD of the frontmost layer of the six layers (the region extending outward in the horizontal direction CD from the second vertical fold FL12) may be shorter than the length in the horizontal direction CD of the region between the first vertical fold FL11 and the second vertical fold FL12. Because the sheet layers 2 stacked in the first region 10 have different lengths in the horizontal direction CD, it becomes easier to grasp one of the sheet layers 2 stacked in the first region 10 and to unfold the sheet layer 2.

[0032] The vertical distance G1 (see FIG. 3 ) between the first vertical edge 11 and the second vertical edge 21 may be 5 mm or more and 10 mm or less. A distance G1 of 5 mm or more between the first vertical edge 11 and the second vertical edge 21 makes it easy to grasp the misaligned portion of the sheet layer 2 with your fingers. Generally, when impregnating the sheet layer 2 with liquid, the liquid is supplied from the starting fold FL1 side while the sheet layer 2 is folded. The liquid diffuses in the planar direction, allowing the liquid to penetrate the entire sheet layer 2 in the folded state. If the distance G1 between the first vertical edge 11 and the second vertical edge 21 is too long, the liquid may not penetrate the entire extended portion of the first region 10 and the second region 20, resulting in uneven impregnation. However, a distance G1 of 10 mm or less between the first vertical edge 11 and the second vertical edge 21 can prevent uneven impregnation. In order to configure the sheet layer 2 so that it can be easily unfolded from the folded state, the distance G2 (see FIG. 3) between the first lateral edge 12 and the second lateral edge 22 in the lateral direction CD may be 5 mm or more.

[0033] As shown in FIG. 1 , the packaging bag 90 has an opening region R10 where an opening for inserting and removing the skin care sheet can be formed. The opening region R10 is an area where an opening is formed by a slit, perforation, a mark indicating the cutting position with scissors, or the like. The opening region R10 is provided at one end of the packaging bag 90 in the longitudinal direction. In this embodiment, the opening region R10 is provided at the end opposite the starting fold FL1 of the two sheets in the longitudinal direction LD, and is an area where an opening is formed by notches 95 formed on both sides of the packaging bag 90 in the transverse direction CD. The first longitudinal edge 11 and the second longitudinal edge 21 of the skin care sheet are located on the opening region R10 side. According to this embodiment, when an opening is formed in the opening region R10, a user can insert a finger through the opening and grasp at least one of the first longitudinal edge 11 and the second longitudinal edge 21 to remove the sheet layer 2. Following this removal operation, the sheet layer 2 can be easily unfolded.

[0034] Next, a skin care sheet 1 according to a modification will be described with reference to FIG. 6. In the following description, the same reference numerals will be used to designate components similar to those in the above-described embodiment, and the description will be omitted. FIG. 6 shows the unfolded and folded states of sheet layers 2A to 2F of skin care sheets according to Modifications 1 to 6. The sheet layer 2A shown in Modification 1 and the sheet layer 2B according to Modification 2 are folded only around the start fold line FL1 in the folded state. The sheet layer 2C according to Modification 3 is folded around a vertical fold line extending in the machine direction LD before the start fold line FL1 extending in the transverse direction CD. The sheet layer 2D according to Modification 4 is folded around a horizontal fold line extending in the same transverse direction CD as the start fold line FL1. This configuration allows all fold lines to run in the same direction, allowing the user to easily grasp the unfolding direction. The sheet layer 2E according to Modification 5 is obtained by further folding the sheet layer 2D according to Modification 4 around a vertical fold line extending in the machine direction CD. The sheet layer 2F according to Modification 6 is circular rather than rectangular in the unfolded state. Even in this circular sheet layer, the first vertical edge 11 and the second vertical edge are different in the folded state, so the sheet layer can be easily unfolded from the folded state.

[0035] Although the present invention has been described in detail using the above-described embodiments, it will be apparent to those skilled in the art that the present invention is not limited to the embodiments described herein. The present invention can be implemented in modified and altered forms without departing from the spirit and scope of the present invention as defined by the claims. Therefore, the description in this specification is intended to be illustrative and does not have any limiting meaning on the present invention. [Industrial Applicability]
