FIG. 6 is a diagram showing a skin care sheet according to a modified example.

(1) Outline of Embodiment At least the following matters will be clarified by the description of this specification and the accompanying drawings.
In the skin care sheet according to one embodiment, a sheet layer having a basis weight of 45 g / m ² or more and 70 g / m ² or less is impregnated with a liquid of 400% by weight or more and 600% by weight or less, and the sheet layer is folded from a crease as a base point. It is stored in a packaging bag in a folded state. The crease has a start crease that serves as a starting point for the first unfolding when the sheet layer is unfolded from the folded state. The sheet layer in the folded state has a first region and a second region arranged in a horizontal direction along the start fold, a vertical direction orthogonal to the horizontal direction, and sandwiched between the start folds and laminated with each other. Have. The first region has a first vertical edge that is the vertical edge and is located on the opposite side of the start crease, and a first horizontal edge that is located on one side of the horizontal direction. The second region has a second vertical edge that is the vertical edge and is located on the opposite side of the start crease, and a second horizontal edge that is located on one side of the horizontal direction. .. The first vertical edge and the second vertical edge are offset in the vertical direction. The first lateral edge and the second lateral edge are offset in the lateral direction. According to this aspect, since the first vertical edge of the first region and the second vertical edge of the second region are vertically displaced, the user can grasp the displaced portion to obtain the first. The region and the second region can be easily separated and the sheet layer can be developed from the starting crease. Similarly, since the first lateral edge of the first region and the second lateral edge of the second region are laterally displaced, the user can grasp the displaced portion to obtain the first region and the first region. The two regions can be easily peeled off and the sheet layer can be developed from the starting crease. In a skin care sheet impregnated with a large amount of liquid of 400% by weight or more and 600% by weight or less, even when the surface tension between the sheet layers becomes high, it can be easily deployed and operability at the time of deployment. Can be improved.

According to a preferred embodiment, the sheet layer has a front surface extending in a plane direction and a back surface opposite to the front surface. An uneven structure is formed on at least one of the front surface and the back surface. According to this aspect, an uneven structure is formed on the front surface or the back surface of the sheet layer, or an uneven structure is formed on both the front surface and the back surface of the sheet layer. The surface tension of the surface that comes into contact with the uneven structure is reduced, and the resistance during deployment is reduced. Therefore, the user can more easily develop the sheet layer.

According to a preferred embodiment, the uneven structure is formed on at least one of a surface facing the second region in the first region and a surface facing the first region in the second region. According to this aspect, when unfolding with the start crease as a base point, the first region and the second region are easily peeled off, the sheet layer can be easily unfolded, and the operability at the time of unfolding can be improved.

According to a preferred embodiment, the uneven structure is formed only on one of the front surface and the back surface. The surface area of the surface having the uneven structure tends to increase when it comes into contact with the skin due to the uneven structure, and by applying the surface having the uneven structure to the skin, the effect of applying liquid and the effect of wiping off dirt can be enhanced. At this time, since the uneven structure is arranged on only one surface, the user can grasp the surface on which the uneven structure to be applied to the skin is formed by the tactile sensation.

According to a preferred embodiment, the concave portion of the uneven structure is a low basis weight portion having a lower basis weight than the convex portion. According to this aspect, since a portion having a different basis weight is formed in the sheet layer, a shade due to the difference in the basis weight is formed in the sheet layer. When the dirt is wiped off with a skin care sheet, the dirt becomes more noticeable due to the shade of the surroundings. In addition, the area where dirt is attached to the sheet layer can be easily grasped by the shade, and the unused range can be easily grasped.

According to a preferred embodiment, the sheet layer in the folded state is folded with the start fold as a base point and also with the vertical fold along the vertical direction as a base point. According to this aspect, since the sheet layer is folded in the first region and the sheet layer is folded in the second region, the laminated sheet layers are likely to be displaced from each other, and the sheet layer is easily displaced from each other. The knob portion is formed in a large number of regions, which makes it easier for the user to develop the sheet layer.

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 aspect, since the distance between the first vertical end edge and the second vertical end edge is 5 mm or more, it is easy to grasp the portion where the sheet layer is displaced with a finger. Further, in general, when impregnating a liquid, the sheet layer is in a folded state, and the liquid is supplied from the start fold side constituting the crease, and the liquid is diffused in the plane direction to form the folded sheet layer. Infiltrate the liquid throughout. At this time, if the distance between the first vertical edge and the second vertical edge is too long, the liquid may not permeate the entire extended portion of the first region and the second region, and impregnation unevenness may occur. .. 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.

The sheet package 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 in which an opening for putting in and taking out the skin care sheet can be formed. The opening area is provided on one end side of the packaging bag in the vertical direction. The first vertical edge and the second vertical edge of the skin care sheet are arranged on the opening region side. According to this aspect, when the opening is formed in the opening area, the user inserts a finger from the opening and grabs at least one of the first vertical edge and the second vertical edge to take out the sheet. be able to. Following the take-out operation, the sheet layer unfolding operation can be easily performed.

(2) Overall Outline Configuration of Skin Care Sheet and Sheet Package According to the Embodiment The skin care sheet and the sheet package according to the embodiment will be described below with reference to the drawings. In the description of the drawings below, the same or similar parts are designated by the same or similar reference numerals. However, it should be noted that the drawings are schematic and the ratio of each dimension is different from the actual one. Therefore, the specific dimensions, etc. should be determined in consideration of the following explanation. In addition, there may be a portion where the relationship and ratio of the dimensions of the drawings are different from each other.

FIG. 1 is a perspective view of the sheet package 100 according to the embodiment. FIG. 2 is a perspective view of the skin care sheet 1 according to the embodiment. FIG. 3 is a plan view of the skin care sheet 1. FIG. 4 is a sectional view taken along the line AA shown in FIG. 3, and FIG. 5 is an enlarged schematic view of a portion B of FIG. The sheet package 100 has a skin care sheet 1 and a packaging bag 90 for packaging the skin care sheet 1. One skin care sheet 1 may be housed in the packaging bag 90, or a plurality of skin care sheets 1 may be housed in the packaging bag 90. In the present embodiment, one skin care sheet 1 is housed in the packaging bag 90. The skin care sheet 1 is sealed in the packaging bag 90 before use, and deterioration before use is suppressed.

The skin care sheet 1 is a sheet that is applied to the user's skin and may be a face sheet or a body sheet. The skin care sheet 1 is a wet sheet impregnated with a liquid of 400% by weight or more and 600% by weight or less. The liquid may be a cleansing agent, a moisturizer, a lotion, an alcohol, a disinfectant, or the like, as long as it is applied to the body. The present embodiment is a makeup wipe sheet impregnated with a cleansing agent. The weight is not the weight of the liquid in the packaging bag 90, but the weight of the liquid held in the skin care sheet 1. The weight% can be calculated by the following method. One skin care sheet 1 is taken out from the packaging bag 90, and the weight of the entire skin care sheet 1 is measured. Let A be the weight of the skin care sheet 1. Next, the skin care sheet 1 is dried until it becomes absolutely dry, and the weight of the dried skin care sheet alone is measured. Let B be the weight of the skin care sheet. The weight% is calculated by (AB) / B. The absolute dry state is a state in which all the chemicals (including non-volatile components) are dried and only the non-woven fabric remains.

The skin care sheet 1 has a sheet layer 2 having a basis weight of 45 g / m ² or more and 70 g / m ² or less. The sheet layer 2 may be composed of a base material (for example, non-woven fabric, gauze, cotton sheet, tissue paper) formed by forming a fiber material into a sheet shape. According to the sheet layer 2 having a basis weight of 45 g / m ² or more and 70 g / m ² or less, the sheet layer 2 is not easily torn when applied to the skin, holds a certain amount of liquid, and easily keeps applying the liquid to the skin. The sheet layer 2 is housed in the packaging bag 90 in a folded state in which the sheet layer 2 is folded from the crease as a base point. The folded skin care sheet 1 is a skin care sheet taken out from the packaging bag 90, and is folded with one or a plurality of folds as a base point.

The crease has a start crease FL1 which is a base point of the first unfolding when the sheet layer 2 is unfolded from the folded state. The user takes out the skin care sheet 1 from the packaging bag 90 and then uses it as it is or unfolds it for use. The start crease FL1 is a crease that serves as a base point when the sheet layer 2 is first developed, in other words, is a crease in the final folding step when the sheet layer 2 is folded. As shown in FIG. 2, the folded sheet layer 2 has a horizontal CD along the start fold FL1 and a vertical LD orthogonal to the horizontal CD. The horizontal CD and the vertical LD extend in the plane direction and are orthogonal to each other. In the present invention, the form extending in a certain direction is a concept including not only a configuration parallel to the direction but also a configuration having an angle of less than 15 degrees with respect to the direction.

The sheet layer 2 in the folded state is arranged with the start fold FL1 interposed therebetween, and has a first region 10 and a second region 20 laminated on each other. The first region 10 is the first vertical end edge 11 which is the end edge of the vertical LD and is located on the opposite side of the start fold FL1, and the first start which is the end edge of the vertical LD and is located on the start fold side. It may have an edge 13, a first lateral edge 12 located on one side of the lateral CD, and a first other end edge 14 located on the other side of the lateral CD. The first region is a region surrounded by a first vertical edge 11, a first horizontal edge 12, a first start edge 13, and a first end edge 14. The first vertical end edge 11 and the first start edge 13 extend in the lateral direction CD. The first horizontal end edge 12 and the first other end edge 14 extend in the vertical direction LD. The first start edge 13 may coincide with the start crease FL1. The second region 20 is the second vertical end edge 21 which is the end edge of the vertical LD and is located on the opposite side of the start fold FL1, and the second start which is the end edge of the vertical LD and is located on the start fold side. It may have an edge 23, a second lateral edge 22 located on one side of the lateral CD, and a second other end edge 24 located on the other side of the lateral CD. The second region 20 is a region surrounded by a second vertical edge 21, a second horizontal edge 22, a second start edge 23, and a second other end edge 24. The second vertical end edge 21 and the second start edge 23 extend in the lateral direction CD. The second horizontal end edge 22 and the second other end edge 24 extend in the vertical direction LD. The second start edge 23 may coincide with the start crease FL1.

The first vertical edge 11 and the second vertical edge 21 are offset in the vertical LD. That is, the length of the vertical LD of the first region 10 and the length of the vertical LD of the second region 20 do not match. Since the first vertical end edge 11 of the first region 10 and the second vertical end edge 21 of the second region 20 are displaced in the vertical direction LD, the user can grasp the displaced portion to obtain the first region. 10 and the second region 20 can be easily peeled off, and the sheet layer 2 can be developed with the start crease FL1 as a base point. Further, the first horizontal edge 12 and the second horizontal edge 22 are displaced in the lateral CD. The user can easily peel off the first region 10 and the second region 20 by grasping the displaced portions of the first horizontal edge and the second horizontal edge, and the sheet layer 2 is formed from the start crease FL1 as a base point. Can be deployed. Preferably, the first other end edge 14 and the second other end edge 24 may also be displaced in the lateral CD. The user can easily peel off the first region 10 and the second region 20 by grasping the misaligned portions on the first end edge 14 and the second end edge 24 side, and use the start crease FL2 as a base point. The sheet layer 2 can be developed. When a plurality of sheet layers are laminated in the first region 10 and the second region 20, the edge is defined by the outermost edge of the laminated sheet layers. According to this aspect, in the skin care sheet 1 impregnated with a large amount of liquid of 400% by weight or more and 600% by weight or less, even when the surface tension between the sheet layers 2 becomes high, it can be easily developed. And the operability at the time of deployment can be improved. Further, since the sheet layer 2 can be easily deployed, the sheet layer 2 can be folded and housed compactly.

The sheet layer 2 has a front surface 81 extending in the plane direction and a back surface 82 opposite to the front surface 81. The front surface 81 and the back surface 82 are surfaces in the unfolded sheet layer 2. An uneven structure 85 may be formed on at least one of the front surface 81 and the back surface 82. The uneven structure 85 refers to irregularly formed unevenness rather than irregular unevenness due to the presence or absence of fibers. The convex portions and concave portions constituting the concave-convex structure 85 have different thicknesses and can be formed by embossing or a low basis weight portion. According to this aspect, the concavo-convex structure 85 is formed on the front surface 81 or the back surface 82 of the sheet layer 2, or the concavo-convex structure 85 is formed on both the front 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, and the resistance during deployment is reduced. Therefore, the user can more easily develop the sheet layer. The height of the uneven structure is not particularly limited. However, preferably, the thickness difference between the concave portion and the convex portion may be 200 μm or more, the thickness difference between the concave portion and the convex portion may be half or less of the thickness of the convex portion, and the width of the convex portion shall be 2.0 mm or more. It may be there.

Hereinafter, the time until the folded skin care sheet was unfolded was measured using the skin care sheet according to the comparative example having no uneven structure and the skin care sheet according to the embodiment. The skin care sheet according to the comparative example and the skin care sheet according to the embodiment are folded in the same manner. Each of the five testers unfolded each sheet three times and measured the time until unfolding. The measurement results are shown in Table 1. As shown in Table 1, it was found that the unfolding time changed significantly depending on the presence or absence of the uneven structure. According to the skin care sheet having an uneven structure, the unfolding operation can be smoothly performed and the unfolding operation can be performed quickly.

As shown in FIG. 4, the concave-convex structure 85 has at least a first facing surface 15 facing the second region 20 in the first region 10 and a second facing surface 25 facing the first region 10 in the second region 20. It is formed on one side. The concave-convex structure 85 of the present embodiment is formed on both the first facing surface 15 and the second facing surface 25. According to this aspect, when unfolding with the start crease FL1 as a base point, the first region 10 and the second region 20 are easily peeled off, the sheet layer 2 can be easily unfolded, and the operability at the time of unfolding is improved. Can be improved.

The uneven structure 85 may be provided on at least one of the front back surface 6 (see FIG. 4) located on the back side of the front surface 5 located on the frontmost side of the sheet layer 2 and the first facing surface 15. As a result of various investigations by the applicant, many users put their index fingers on the first facing surface 15 and their thumbs on the front surface 5 when opening the package with the start crease FL1 as the base point, or in front of them. It was found that the sheet layer 2 was gripped and unfolded with the thumb on the front surface 5 and the index finger on the front back surface 6 on the back side of the front surface 5. When the sheet layer 2 is unfolded while the sheet layer 2 is gripped in this way, the surface on which the concave-convex structure 85 is formed hits the index finger, and the opposite surface hits the thumb. Further, depending on the user, the sheet layer 2 may be unfolded and then folded for use. At this time, in general, the user folds the thumb with the side on which the thumb is located toward the front and the front side toward the inside. Therefore, in the folded state, a surface on which the uneven structure 85 is formed is arranged on the outside of the sheet layer. The user can use the skin care sheet by touching the skin on which the uneven structure 85 is formed without being aware of it. The surface area of the surface having the uneven structure 85 tends to increase when it comes into contact with the skin due to the uneven structure 85, and by applying the surface having the uneven structure to the skin, the effect of applying liquid and the effect of wiping off dirt can be enhanced. can.

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 area of the surface having the uneven structure 85 tends to increase when it comes into contact with the skin due to the uneven structure 85, and by applying the surface having the uneven structure 85 to the skin, the effect of applying liquid and the effect of wiping off dirt are enhanced. Can be done. At this time, since the uneven structure 85 is arranged on only one surface, the user can grasp the surface on which the uneven structure 85 to be touched to the skin is formed by tactile sensation.

The concave portion of the concave-convex structure 85 may be a low basis weight portion having a lower basis weight than the convex portion. Since the sheet layer 2 is formed with portions having different basis weights, the sheet layer 2 is formed with shades due to the difference in basis weight. When the dirt is wiped off by the skin care sheet 1, the dirt becomes conspicuous due to the shade of the surroundings. In addition, it is easy to grasp the range where dirt is attached to the sheet layer 2 by shading, and it is possible to easily grasp the unused range.

The sheet layer 2 in the folded state may be folded with the start fold FL1 as the base point and may be folded with the vertical folds FL11 and FL12 along the vertical direction as the base points. The sheet layer 2 of the present embodiment is folded with a plurality of folds as base points in addition to the start fold FL1. More specifically, the sheet layer 2 is folded from the unfolded state with the first vertical fold FL11 and the second vertical fold FL12 extending in the vertical direction as the base point, and then folded with the start fold FL1 as the base point. Therefore, the folded sheet layer 2 is laminated in 6 layers. According to this configuration, since the sheet layer 2 is folded in the first region 10 and the sheet layer 2 is folded in the second region 20, the laminated sheet layers are likely to be displaced from each other. , The knob portion of the sheet layer 2 is formed in a large number of regions, which makes it easier for the user to develop the sheet layer 2. Further, since it is folded in both the vertical direction LD and the horizontal direction CD, the sheet layer 2 can be compactly accommodated.

The skin care sheet 1 of the present embodiment is folded with the first vertical fold FL11 and the second vertical fold FL12 as the base points, and the lengths of the three layers of the horizontal CDs are substantially the same. However, preferably, the length of the horizontal CD of the layer located on the foremost side of the six layers (the region extending from the second vertical fold FL12 to the outside of the horizontal CD) is the first vertical fold FL11 and the second. It may be shorter than the length of the lateral CD in the area between the vertical creases FL12. Since the lengths of the lateral CDs are different in the sheet layers 2 laminated in the first region 10, it becomes easier to grasp one of the laminated sheet layers 2 in the first region 10, and the sheet layer 2 is separated. Easy to deploy.

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. Since the distance G1 between the first vertical end edge 11 and the second vertical end edge 21 is 5 mm or more, it is easy to grasp the portion where the sheet layer 2 is displaced with a finger. Further, in general, when impregnating the liquid, the liquid is supplied from the start fold FL1 side in the folded state of the sheet layer 2, and the liquid is diffused in the plane direction to diffuse the entire sheet layer 2 in the folded state. Infiltrate the liquid. At this time, if the distance G1 between the first vertical edge 11 and the second vertical edge 21 is too long, the liquid does not permeate the entire extended portion of the first region 10 and the second region 20, and the impregnation unevenness occurs. May occur. However, since the distance G1 between the first vertical edge 11 and the second vertical edge 21 is 10 mm or less, uneven impregnation of the liquid can be suppressed. Further, in order to easily deploy the sheet layer 2 from the folded state, the distance G2 (see FIG. 3) between the lateral CDs of the first lateral edge 12 and the second lateral edge 22 is 5 mm or more. You may.

As shown in FIG. 1, the packaging bag 90 has an opening region R10 in which an opening for putting in and taking out a skin care sheet can be formed. The opening area R10 is an area in which an opening is formed by a mark portion indicating a position to be cut by a notch, a perforation, a scissors, or the like. The opening area R10 is provided on one end side in the vertical direction of the packaging bag 90. In this embodiment, the sheet layer 2 is provided at the end opposite to the start fold FL1 of the sheet layer 2 in the vertical direction LD, and the opening is formed by the notches 95 formed on both sides of the horizontal CD of the packaging bag 90. This is the area to be used. The first vertical edge 11 and the second vertical edge 21 of the skin care sheet are arranged on the opening region R10 side. According to this aspect, when the opening is formed in the opening region R10, the user inserts a finger from the opening and grabs at least one of the first vertical edge 11 and the second vertical edge 21. The sheet layer 2 can be taken out. Following the take-out operation, the sheet layer 2 can be easily developed.

Next, the skin care sheet 1 according to the modified example will be described with reference to FIG. In the following description, the same components as those in the above-described embodiment will be described with reference to the same reference numerals. FIG. 6 shows the unfolded state and the folded state of the sheet layers 2A to 2F of the skin care sheet according to the modified examples 1 to 6. The sheet layer 2A shown in the modified example 1 and the sheet layer 2B according to the modified example 2 are folded only at the start fold FL1 in the folded state. The sheet layer 2C according to the third modification is folded before the start crease FL1 extending in the horizontal direction CD with the vertical fold extending in the vertical direction LD as a base point. The sheet layer 2D according to the modified example 4 is folded with a horizontal fold extending in the same horizontal direction CD as the start fold FL1 as a base point. According to this configuration, all the fold lines follow the same direction, so that the user can easily grasp the deployment direction. The sheet layer 2E according to the modified example 5 further folds the sheet layer 2D according to the modified example 4 with a vertical crease extending in the vertical direction as a base point. The sheet layer 2F according to the modified example 6 is not a rectangle but a circle in the expanded state. Even in the circular sheet layer, since the first vertical end edge 11 and the second vertical end edge are different in the folded state, the sheet layer can be easily unfolded from the folded state.
