(2) Configuration of absorbent article packaging body The absorbent article packaging body according to the embodiment will be described below with reference to the drawings. In the following description of the drawings, the same or similar parts are denoted by the same or similar reference numerals. However, it should be noted that the drawings are schematic and ratios of dimensions and the like are different from actual ones. Therefore, specific dimensions and the like should be determined in consideration of the following description. Moreover, the part from which the relationship and ratio of a mutual dimension differ also in between drawings may be contained.

  FIG. 1 is a perspective view of an absorbent article packaging body according to the first embodiment, and FIG. 2 is a cross-sectional view of the absorbent article packaging body taken along line AA in FIG. 1. The absorbent article packaging body 1 (hereinafter referred to as the packaging body 1) includes an absorbent article 20 and a packaging sheet 10 for packaging a plurality of absorbent articles 20.

  The packaging sheet 10 is formed in a bag shape. A plurality of absorbent articles 20 are accommodated in the space in the packaging sheet 10. Examples of the absorbent article 20 include disposable diapers, sanitary napkins, and absorbent pads. The absorbent article 20 of this Embodiment is a disposable diaper, and may be accommodated in the packaging sheet 10 in the state folded in half. The absorbent article 20 may have a thickness direction T, a longitudinal direction along the front-rear direction of the absorbent article 20, and a width direction orthogonal to the longitudinal direction and the thickness direction T.

  FIG. 3 is an enlarged view of a portion B shown in FIG. The front surface 10 </ b> T of the packaging sheet 10 may constitute the outer surface of the packaging body 1, and the rear surface 10 </ b> B of the packaging sheet 10 may constitute the inner surface of the packaging body 1 and may contact the absorbent article 20.

  The packaging sheet 10 may have an uneven portion 15 provided on the surface of the packaging sheet 10. The concavo-convex portion 15 is provided on the surface 10T of the packaging sheet 10 and diffusely reflects light hitting the surface 10T of the packaging sheet 10. A decorative effect can be exhibited by irregular reflection of light. The glossiness of the front surface 10T of the packaging sheet 10 may be lower than the glossiness of the back surface 10B of the packaging sheet 10. More preferably, the glossiness of the front surface 10T of the packaging sheet 10 may be 1/2 times or less than the glossiness of the back surface 10B of the packaging sheet 10. The effect of irregularly reflecting light by the surface 10T of the packaging sheet 10 can be obtained more suitably. The more light is reflected by the surface of the packaging sheet, the more difficult it is to see the absorbent article inside the packaging sheet. Therefore, the decorative effect intended by the packaging sheet can be exhibited. The glossiness can be measured by a measurement method based on a specular glossiness-measurement method (JIS Z 8741) using a gloss meter VG7000 manufactured by Nippon Denshoku Industries Co., Ltd., and has a gloss of 60 °.

  The back surface 10B of the packaging sheet 10 may be smoother than the front surface 10T of the packaging sheet 10. Examples of the index for comparing the smoothness of the sheet include the unevenness of the surface, the standard deviation (SMD) of the surface roughness of KES, and the average deviation (MMD) of the average friction coefficient. Specifically, the height of the unevenness of the cross section of the sheet can be measured by an electron microscope. When the height of the unevenness on the back surface of the packaging sheet is lower than the height of the unevenness on the surface of the packaging sheet, the back surface 10B of the packaging sheet 10 is smoother than the surface 10T of the packaging sheet 10. In addition, when measuring the standard deviation (SMD) of the surface roughness of KES, the shape of the irregularities on the surface opposite to the measurement surface is affected, so that only the layer constituting the surface to be measured is taken out and measured. Is preferred. Since the back surface of the packaging sheet is smoother than the surface of the packaging sheet, it is possible to suppress the frictional resistance when the absorbent article is taken out. When the absorbent article is taken out, the absorbent article is not easily caught on the back surface of the packaging sheet, and the user can easily take out the absorbent article smoothly. Since there are uneven portions on the surface of the packaging sheet and the back surface of the packaging sheet is smooth, the absorbent article can be smoothly taken out during use while exhibiting the intended decorative effect by the uneven portions on the surface of the packaging sheet.

  The packaging sheet 10 may have a main body layer 11 disposed on the back side of the uneven portion 15. The main body layer 11 may be disposed on the back surface of the packaging sheet. The main body layer 11 may be constituted by a film having a thickness of 0.04 mm to 0.20 mm. The back surface of the main body layer 11 is substantially smooth. Specifically, the standard deviation (SMD) of the surface roughness of KES on the back surface of the main body layer 11 is 0.8 or less, and more preferably 0.2 or more and 0.3 or less. The average deviation (MMD) of the average friction coefficient of KES on the back surface of the main body layer is 0.01 or less, and more preferably 0.004 or more and 0.006 or less. The standard deviation of the thickness of the main body layer 11 may be 10% or less of the average thickness of the main body layer 11. Further, the surface of the main body layer 11 may be substantially smooth like the back surface of the main body layer 11. Since the surface of the main body layer 11 is substantially smooth, unevenness hardly occurs when the colored layer 12 and the resin layer 13 are formed on the front surface side of the main body layer 11. Therefore, it is easy to form the colored layer 12 and the resin layer 13 in the intended mode, and the decorative effect intended by the irregular reflection or coloring of light can be exhibited.

  Since the back surface of the main body layer 11 is substantially smooth, processing irregularities are unlikely to occur when the main body layer 11 is subjected to decorative processing such as the formation of the concavo-convex portion 15. Therefore, the concavo-convex portion 15 can be processed in the manner intended for the main body layer 11, and the intended decorative effect is easily exhibited by the concavo-convex portion 15. Moreover, the back surface of the main body layer 11 may constitute the back surface 10B of the packaging sheet 10, and the back surface 10B of the packaging sheet 10 may be substantially smooth.

  The measurement of the mean deviation (MMD) of the surface friction coefficient and the mean deviation (SMD) of the surface roughness is generally known as a characteristic value representing the feel of the surface of the sheet, with KES manufactured by Kato Tech Co., Ltd. It can be measured on the basis of characteristic values (reference: standardization and analysis of texture evaluation (2nd edition), author published by Toshio Kawabata, July 10, 1980).

  Specifically, the surface characteristics are measured using a KES-FB4 manufactured by Kato Tech Co., Ltd., with each sample having a 1.0 × 1.0 cm range as a sample, and placed on a smooth metal flat test bench. I went. The surface roughness is measured by applying a load of 10 gf on the front surface (or the back surface) and pressing a contact terminal having a width of 0.5 cm wound with a 0.5 mm diameter piano wire on the sample, Further, the surface friction is measured by arranging ten piano wires which are the same as the contact terminals used for measuring the surface roughness and pressing the contact surface against the sample with a force of 50 fg using a weight. In the measurement of surface friction and surface roughness, the sample is moved 2 cm horizontally at a constant speed of 0.1 cm / sec, and a uniaxial tension of 20 gf / cm is applied to the sample. From the measurement results, the average deviation (MMD) of the surface friction coefficient and the average deviation (SMD) of the surface roughness were obtained.

  The thickness of the main body layer 11 can be measured by the following method. After the body layer 11 is conditioned for 2 hours at 23 ° C. × 50% RH, the reference direction (0 degree direction) is specified around an arbitrary point A of the body layer 11, and then the reference direction (a ), 45 degree direction clockwise (b), 90 degree direction (c), 135 degree direction (d), 180 degree direction (e), 225 degree direction (f), 270 degree direction (g) ) And 315 degrees direction (h) are drawn in a total of eight straight lines L1 to L8 each having a length of 100 mm. On each straight line, the thickness is measured with a length gauge “HEIDENHAIN-METRO MT1287” (manufactured by HEIDENHAIN) at 10 mm intervals from the center point (measured at 10 points). And the average value of the measured value of 80 data total obtained by measuring in all the straight lines is calculated, this is made into average thickness, and the standard deviation value with respect to average thickness is calculated.

Moreover, the bending rigidity of the packaging sheet 10 may be 0.07 × 10 ⁻⁴ Nm / m or more, and the bending resistance of the packaging sheet 10 may be 53.0 mm or more. Since the bending rigidity of the packaging sheet 10 is 0.07 × 10 ⁻⁴ N or more, the bending resistance of the packaging sheet 10 is 53.0 mm or more, and the packaging sheet has a strain, Non-uniformity of decoration processing hardly occurs. Therefore, the concavo-convex portion 15 can be processed in the manner intended for the main body layer 11, and the intended decorative effect is easily exhibited by the concavo-convex portion 15.

  The bending resistance of the packaging sheet 10 is measured according to JIS L 1913 6.7.3. More specifically, five 38 mm × 25 mm test pieces were collected, and the front and back surfaces of the test pieces were continuously measured with a Gurley tester (Yasuda Seiki Seisakusho Co., Ltd., bending resistance measuring instrument No. 311). The bending resistance is calculated from the average value of the front and back sides.

  The bending rigidity of the packaging sheet 10 is measured using KES FB-2 manufactured by Kato Tech Co., Ltd. A test piece having a size of 50 mm × 100 mm is prepared, one end of the test piece in the longitudinal direction is sandwiched between one of the pair of chucks, and the other end in the longitudinal direction of the test piece is sandwiched between the other chucks. One chuck rotates around the other chuck, and the bending rigidity of the test piece bent by this is measured with a torque detector. Five sets of test pieces are prepared, and the average value of the measured values is defined as bending rigidity.

  The concavo-convex portion 15 may be constituted by the resin layer 13 disposed on the surface side of the main body layer 11. The resin layer 13 is cured by predetermined processing (temperature adjustment, ultraviolet irradiation). Therefore, it is easy to realize a desired shape of the uneven portion 15. Therefore, the height of the concavo-convex portion 15 is increased to enhance the reflection effect, the height of the concavo-convex portion 15 is partially changed to partially change the reflection mode, or the concavo-convex portion 15 of the packaging sheet 10 is intended. It is easy to demonstrate the decorative effect. The height H15 of the concavo-convex portion 15 is the distance in the thickness direction between the apex of the convex portion and the bottom surface of the dent (see FIG. 6). The height of the uneven portion 15 may be 0.8 μm or more. The height of the uneven portion 15 is preferably 1.2 μm or more, more preferably 1.5 μm or more. When the height of the concavo-convex portion is 0.8 μm or more, the effect of irregularly reflecting the light hitting the surface of the packaging sheet can be more suitably obtained. Further, the height of the concavo-convex portion is preferably 1.2 μm or more, and more preferably 1.5 μm or more, whereby the light irregular reflection effect can be further enhanced. In addition, the uneven | corrugated | grooved part 15 may be formed in the main body layer 11, and may be comprised by the layer separate from a main body layer, such as the resin layer 13 and the colored layer 12 mentioned later.

  The resin layer 13 may include an ultraviolet curable resin. Since the resin layer 13 constituting the concavo-convex portion 15 has an ultraviolet curable resin, the packaging sheet 10 can easily absorb ultraviolet rays. If the absorbent article 20 in the packaging sheet 10 is excessively irradiated with ultraviolet rays, the absorbent article may deteriorate or the indicator may react unintentionally. When the resin layer 13 includes the ultraviolet curable resin, it is possible to suppress the influence of the ultraviolet rays on the absorbent article 20 packaged in the packaging sheet 10.

  The packaging sheet 10 may have a colored layer 12 disposed between the main body layer 11 and the resin layer 13. Since the packaging sheet 10 has the colored layer 12, the packaging sheet 10 can exhibit the decorative effect of the colored layer 12. Moreover, since the main body layer 11 is a substantially smooth surface, the colored layer 12 can be provided in an intended shape, such as making the dot diameter of the colored layer 12 constant, and the decorative effect intended by the packaging sheet 10 can be obtained. Can demonstrate.

  The colored layer 12 may be constituted by an aggregate of dots. The standard deviation of the dot diameter constituting the colored layer is 10% or less of the average diameter, and more preferably 5% or less of the average diameter. FIG. 4 is an enlarged plan view schematically showing the surface of the packaging sheet. As shown in FIG. 4, the surface of the packaging sheet may be provided with concavo-convex portions 15 and dots of the colored layer 12 located on the back side of the concavo-convex portions 15 so as to be visible. The colored layer 12 is partially disposed, and a region where the colored layer 12 is disposed and a region where the colored layer is not disposed may be provided. The dot diameter is a dot diameter in plan view. In FIG. 4, the dots are denoted by reference numerals 121 and 122, and the dot diameters are denoted by D121 and D122. Since the standard deviation of the dot diameter is 10% or less of the average diameter, the dot diameter is substantially uniform. Therefore, color unevenness of the colored layer 12 is less likely to occur, and the intended decorative effect is easily exhibited by the colored layer 12. The standard deviation of the dot diameter is an index of variation in the dot diameter. When the average particle size (diameter in plan view) of the dots is x and the standard deviation is σ, the variation in particle size represented by σ / x is 10% or less, more preferably 5% or less. It is preferable.

  Among the plurality of dots, the standard deviation of the diameters of the dots constituting the same color is 10% or less of the average diameter, and more preferably 5% or less of the average diameter. The dots constituting the same color refer to dots constituting a color having the same hue, lightness, and saturation. In FIG. 4, a dot 121 is a dot constituting the same color, and a dot 122 is a dot constituting the same color. The dots 121 and 122 are dots constituting different colors and have different diameters. Since the diameters of dots constituting the same color are substantially uniform, the coloring effect of the same color can be made uniform, and the intended decoration effect can be more easily exhibited.

  The dots of the colored layer 12 may be provided in a region that overlaps the concave portion of the uneven portion 15 and a region that overlaps the convex portion. The boundary between the concave portion and the convex portion may be an intermediate point in the thickness direction between the apex of the convex portion and the bottom surface of the concave portion. The region overlapping the concave portion is a region indicated by 15A in FIG. 4, and the region overlapping the convex portion is a region indicated by 15B in FIG. The standard deviation between the dot diameter of the region 15A that overlaps the concave portion and the dot diameter of the region 15B that overlaps the convex portion of the concavo-convex portion is 10% or less of the average diameter, and more preferably 5% or less of the average diameter. It's okay. More preferably, the dot diameter (for example, D121) of the dots constituting the same color among the dots of the region 15A overlapping the concave portion is substantially uniform, and the same color is constituted among the dots of the region 15B overlapping the convex portion. The dot diameter of the dots to be performed (for example, D121) is substantially uniform. Since the dot diameter of the region overlapping the concave portion and the dot diameter of the region overlapping the convex portion are substantially uniform, the coloring effect can be made uniform and the intended decoration effect can be more easily exhibited.

  The colored layer 12 may partially overlap with the resin layer 13, and a region 12A where the resin layer 13 and the colored layer 12 overlap and a region 12B where the resin layer 13 and the colored layer 12 do not overlap are provided. Good. In the region 12B where the resin layer 13 and the colored layer 12 do not overlap, the colored layer 12 may not be disposed, and the main body layer 11 and the resin layer 13 may be disposed. The difference between the height of the uneven portion of the region 12A where the resin layer 13 and the colored layer 12 overlap and the height of the uneven portion of the region 12B where the resin layer 13 and the colored layer 12 do not overlap may be 0.1 μm or less. Since there is no substantial difference between the height of the concavo-convex portion 15 in the region 12A where the resin layer 13 and the colored layer 12 overlap and the height of the concavo-convex portion in the region where the resin layer 13 and the colored layer 12 do not overlap, the resin layer and the colored layer 12 are colored. The substantially same light reflection effect can be exhibited in the region where the layers overlap and the region where the resin layer and the colored layer do not overlap. Therefore, the intended decorative effect is easily exhibited by the uneven portion of the packaging sheet.

  The packaging sheet 10 may be provided with a wearer image 17 that shows an image of the wearer and an identification image 16 that displays identification information such as a product name. The wearer image 17 and the identification image 16 may be configured by the colored layer 12. The wearer image 17 is an image for indicating the wear target person, and may include a part of the wear target person's face and body.

  The uneven part 15 may have a plurality of uneven patterns. The plurality of concavo-convex patterns may be different in at least one of the planar shape of the concavo-convex portion, the height of the concavo-convex portion, and the length and width of the concavo-convex portion. The planar shape of the concavo-convex portion is a shape of the concave portion or the convex portion in a plan view, and includes a rectangle, a circle, and a triangle. Since it has a plurality of concavo-convex patterns, different decorative effects can be exhibited depending on the plurality of reflection patterns. The light hitting the surface 10T of the packaging sheet 10 becomes a complicated reflection mode, and aesthetics can be enhanced. The width of the uneven portions and the interval between the uneven portions may be 2.0 mm or less. The width of the concavo-convex portion is the length of the concave portion or the convex portion in the width direction, and the interval between the concavo-convex portions is the interval between the concave portions or the interval between the convex portions. A fine uneven part is arrange | positioned on the surface of a packaging sheet, and light becomes easy to diffusely reflect on the surface of a packaging sheet. Therefore, the decoration effect by irregular reflection of light can be heightened and the intended decoration effect can be exhibited. Preferably, the width of the concavo-convex portions and the interval between the concavo-convex portions may be 0.5 mm or greater and 1.0 mm or less, further enhancing the irregular reflection effect of light and easily exhibiting the intended decoration effect.

  FIG. 5 is an enlarged plan view of a portion C in a region overlapping with the wearer image. FIG. 6 is a cross-sectional view of the packaging sheet taken along line DD shown in FIG. The dot diameter of the colored layer in the region R1 constituting the eye of the wearer image may be larger than the dot diameter of the colored layer in the region R2 constituting the periphery of the eye of the wearer image. Therefore, the eyes in the wearer image become dark and the eyes can be made conspicuous. The height of the concavo-convex portion 15 in the region R1 constituting the eye may be higher than the height of the concavo-convex portion 15 in the region R2 constituting the periphery of the eye. The reflection effect of the region R1 constituting the eye can be enhanced to make the eye stand out. The irregularities 15 in the region R1 constituting the eyes may be regularly arranged, and the irregularities 15 in the region R2 constituting the periphery of the eyes may be irregularly arranged. The area | region R2 around eyes is an area | region which comprises skin, and can give the texture like skin with an irregular shape.

  The combination of the concavo-convex portion 15 and the colored layer 12 may exhibit a complex decoration effect that matches the image. The concavo-convex pattern of the concavo-convex portion that overlaps the wearer image may be different from the concavo-convex pattern of the identification image. The uneven pattern of the wearer image may be an irregular and fine uneven pattern to make it easy to produce a skin-like texture. The concavo-convex pattern of the concavo-convex portion that overlaps the identification image 16 may employ a regular concavo-convex pattern so that the identification information can be easily viewed. In addition, a fine uneven | corrugated pattern is a pattern with a short width | variety and the length of an uneven | corrugated | grooved part. Specifically, the width of the concavo-convex part in the region constituting the skin may be smaller than the width of the concavo-convex part in the region constituting the other part (around the skin) of the wearer image. The width of the concavo-convex portion of the region constituting the skin is short, and a smooth texture is obtained when the user touches the skin image. The soft texture of the skin image can give a soft impression to the skin and the absorbent article that touches the skin. Moreover, it is preferable that the planar shape of the uneven | corrugated | grooved part of the area | region which comprises skin is an ellipse which is not a perfect circle, or a rectangular shape. When the concavo-convex portion is a regular circle, the concavo-convex portion may exhibit a visual effect like a blowout, and a smooth texture can be provided by being an ellipse or a rectangle.

  As shown in FIG.2 and FIG.3, the absorbent article may be laminated | stacked on the thickness direction. The boundary 23 between the absorbent articles may be along the longitudinal direction and the width direction of the absorbent article. The absorbent article 20 may be made of a flexible material such as a nonwoven fabric, and the corners of the outer shape of the absorbent article are not linear but are likely to be curved. Therefore, the distance D1 between the article surface 22 of the absorbent article disposed opposite to the packaging sheet 10 and the back surface of the packaging sheet 10 is likely to change in the vicinity of the boundary 23 of the absorbent article 20. When the depth from the packaging sheet 10 to the article surface 22 changes, a shadow is generated on the inner side of the packaging sheet 10 and the visual effect when viewed from the surface 10T side of the packaging sheet 10 is likely to change. Specifically, since the shadow is deep at a portion where the depth from the packaging sheet 10 to the article surface 22 is deep, the brightness of the packaging sheet 10 is lowered. Since a shadow becomes thin in the location where the depth from the packaging sheet 10 to the article surface is shallow, the brightness of the packaging sheet 10 becomes high. At least one of the uneven portion 15 and the colored layer 12 may be disposed in a region straddling the boundary 23 between the absorbent articles 20. Since the uneven portion 15 is arranged in a region straddling the boundary 23 of the absorbent article 20, variation in brightness due to the boundary 23 of the absorbent article 20 can be made inconspicuous due to the decorative effect of the uneven portion 15. Therefore, the intended decorative effect of the packaging sheet can be exhibited more. Further, since the colored layer 12 is disposed in a region that crosses the boundary 23 between the absorbent articles, variation in brightness due to the boundary 23 of the absorbent article can be made inconspicuous due to the decoration effect of the colored layer 12.

  The absorbent article 20 has an article surface 22 disposed to face the packaging sheet 10. A colored region 21 may be provided on the article surface 22. FIG. 6 is an enlarged plan view of a portion E shown in FIG. In FIG. 6, a colored region 21 visible through the packaging sheet 10 is shown. The colored region 21 may be provided on the exterior sheet itself that constitutes the outer surface of the absorbent article 20, or may be provided so as to be visible through the exterior sheet. At least one of the concavo-convex portion 15 and the colored layer 12 of the packaging sheet 10 may be disposed in a region overlapping the colored region 21. If the colored region 21 of the absorbent article 20 is too conspicuous when viewed from the outside of the packaging sheet 10, the user may have difficulty grasping the decorative effect of the packaging sheet 10. The colored region 21 of the absorbent article 20 can be made inconspicuous by the decorative effect by the uneven part 15 or the colored layer 12, and the decorative effect of the packaging sheet 10 can be made conspicuous. Therefore, the decorative effect of the intended packaging sheet 10 can be exhibited more.

  The colored region 21 may have a plurality of patterns, and may be configured such that the pattern of the colored region 21 of the adjacent absorbent article is different. When the colored region 21 has a plurality of patterns, the decorative effect of each pattern is exhibited, and the colored region of the absorbent article 20 becomes more conspicuous. The decorative effect of the packaging sheet 10 makes the colored region 21 of the absorbent article 20 inconspicuous, and the decorative effect of the packaging sheet 10 can be easily noticeable.

  As shown in FIG. 6, at least one of the uneven portion 15 and the colored layer of the packaging sheet 10 may extend in a direction intersecting the direction in which the boundary 23 extends. Since the boundary 23 between the absorbent articles is likely to cause a shadow, the brightness of the packaging sheet tends to be low. Since the part which exhibits the decorative effect by the uneven | corrugated | grooved part 15 or the colored layer 12 extends in the direction which cross | intersects with the boundary 23 of absorbent articles, the shadow in the boundary 23 of absorbent articles can be made not conspicuous. Therefore, the intended decorative effect of the packaging sheet can be exhibited more.

  Next, an absorbent article packaging body according to another embodiment will be described. The packaging sheet of the absorbent article packaging body according to another embodiment may not have the main body layer 11. The colored layer 12 of the packaging sheet may also serve as the main body layer 11. The packaging sheet may not have the colored layer 12.
