(2) Structure of Package of Absorbent Articles The package of absorbent articles 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 in which the relationship and ratio of dimensions of the drawings are different from each other.

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

The packaging sheet 10 is formed in a bag shape. A plurality of absorbent articles 20 are housed in the space inside the packaging sheet 10. Examples of the absorbent article 20 include disposable diapers, sanitary napkins, and absorbent pads. The absorbent article 20 of the present embodiment is a disposable diaper, and may be housed in the packaging sheet 10 in a folded state. 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 10T of the packaging sheet 10 constitutes the outer surface of the packaging body 1, and the back surface 10B of the packaging sheet 10 constitutes the inner surface of the packaging body 1 and may come into contact with the absorbent article 20.

The packaging sheet 10 may have an uneven portion 15 provided on the surface of the packaging sheet 10. The uneven portion 15 is provided on the surface 10T of the packaging sheet 10 and diffusely reflects the light that hits the surface 10T of the packaging sheet 10. A decorative effect can be exhibited by diffused 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 the glossiness of the back surface 10B of the packaging sheet 10. The effect of diffusely reflecting light can be more preferably obtained by the surface 10T of the packaging sheet 10. The more light is reflected by the surface of the packaging sheet, the harder it is to see the absorbent articles inside the packaging sheet. Therefore, the intended decorative effect can be exhibited by the packaging sheet. The glossiness can be measured by a measurement method based on the mirror glossiness-measurement method (JIS Z 8741) using a gloss meter VG7000 manufactured by Nippon Denshoku Industries Co., Ltd., and has a glossiness at an angle of 60 °.

The back surface 10B of the packaging sheet 10 may be smoother than the front surface 10T of the packaging sheet 10. As an index for comparing the smoothness of the sheets, the height of the unevenness of the surface, the standard deviation of the surface roughness of KES (SMD), and the average deviation of the average friction coefficient (MMD) can be exemplified. 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 front surface of the packaging sheet, the back surface 10B of the packaging sheet 10 is smoother than the front surface 10T of the packaging sheet 10. Further, when measuring the standard deviation (SMD) of the surface roughness of KES, since the shape of the unevenness of the surface opposite to the measurement surface affects, only the layer constituting the surface to be measured should be taken out and measured. Is preferable. Since the back surface of the packaging sheet is smoother than the front surface of the packaging sheet, frictional resistance at the time of taking out the absorbent article can be suppressed. When taking out the absorbent article, the absorbent article is hard to be caught on the back surface of the packaging sheet, and the user can easily take out the absorbent article smoothly. Since the surface of the wrapping sheet has irregularities and the back surface of the wrapping sheet is smooth, the concave and convex portions on the surface of the wrapping sheet can exert the intended decorative effect, and the absorbent article can be smoothly taken out during use.

The packaging sheet 10 may have a main body layer 11 arranged on the back surface side of the uneven portion 15. The main body layer 11 may be arranged on the back surface of the packaging sheet. The main body layer 11 may be composed of a film having a thickness of 0.04 mm to 0.20 mm. The back surface of the 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 may be 0.8 or less, 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 may be 0.01 or less, more preferably 0.004 or more and 0.006 or less. The standard deviation of the thickness of the body layer 11 may be 10% or less of the average thickness of the body layer 11. Further, the front surface of the main body layer 11 may be substantially smooth as well as the back surface of the main body layer 11. Since the surface of the main body layer 11 is substantially smooth, unevenness is unlikely to occur when the colored layer 12 and the resin layer 13 are formed on the surface side of the main body layer 11. Therefore, the colored layer 12 and the resin layer 13 can be easily formed in the intended manner, and the intended decorative effect can be exhibited by diffused reflection of light or coloring.

Since the back surface of the main body layer 11 is substantially smooth, uneven processing is unlikely to occur when the main body layer 11 is subjected to decorative processing such as formation of uneven portions 15. Therefore, the uneven portion 15 can be processed in the manner intended for the main body layer 11, and the uneven portion 15 can easily exert the intended decorative effect. Further, the back surface of the main body layer 11 may form 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 performed by KES manufactured by Kato Tech Co., Ltd., which is generally known as a characteristic value indicating the feel of the surface of the sheet. It can be measured based on the characteristic values (reference: standardization and analysis of texture evaluation (2nd edition), published by author Kiyo Kawabata, July 10, 1980).

Specifically, for the measurement of surface characteristics, KES-FB4 manufactured by Kato Tech Co., Ltd. was used, and each sample was placed in a range of 1.0 × 1.0 cm on a test table on a smooth metal surface. I went. The surface roughness is measured by applying a load of 10 gf on the front surface (or back surface) and crimping a contact terminal having a width of 0.5 cm wound with a piano wire having a diameter of 0.5 mm to the sample. The surface friction is measured by arranging 10 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 by a weight. In the measurement of surface friction and surface roughness, the sample is moved horizontally by 2 cm at a constant speed of 0.1 cm / sec, and the sample is given a uniaxial tension of 20 gf / cm. From the measurement results, the average deviation of the surface friction coefficient (MMD) and the average deviation of the surface roughness (SMD) were determined.

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

The flexural rigidity of the packaging sheet 10 may be 0.07 × 10 ^-4 Nm / m or more, and the rigidity of the packaging sheet 10 may be 53.0 mm or more. The flexural rigidity of the packaging sheet 10 is 0.07 × 10 ^-4 N or more, the rigidity and softness of the packaging sheet 10 is 53.0 mm or more, and the packaging sheet is stiff, so that uneven portions 15 are formed. Uneven decoration processing is unlikely to occur. Therefore, the uneven portion 15 can be processed in the manner intended for the main body layer 11, and the uneven portion 15 can easily exert the intended decorative effect.

The rigidity and softness 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 sampled, and the front and back of the test pieces were continuously measured with a Garley tester (Rigidity and Softness Measuring Instrument No. 311 manufactured by Yasuda Seiki Seisakusho Co., Ltd.). The rigidity is calculated from the average value on the front and back.

The flexural 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 of the test piece is sandwiched between the other chucks. One chuck rotates around the other chuck, and the flexural rigidity of the test piece bent by this is measured by a torque detector. Five sets of test pieces are prepared, and the average value of the measured values is taken as the bending rigidity.

The uneven portion 15 may be composed of a resin layer 13 arranged on the surface side of the main body layer 11. The resin layer 13 is cured by a predetermined process (temperature adjustment, ultraviolet irradiation). Therefore, it is easy to realize the desired shape of the uneven portion 15. Therefore, the height of the uneven portion 15 is increased to enhance the reflection effect, the height of the uneven portion 15 is partially different to partially different the reflection mode, or the uneven portion 15 of the packaging sheet 10 is intended. It is easy to exert a decorative effect. The height H15 of the uneven portion 15 is the distance between the apex of the convex portion and the bottom surface of the concave portion in the thickness direction (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, and more preferably 1.5 μm or more. When the height of the uneven portion is 0.8 μm or more, the effect of diffusely reflecting the light hitting the surface of the packaging sheet can be more preferably obtained. Further, the height of the uneven portion is preferably 1.2 μm or more, more preferably 1.5 μm or more, so that the diffused reflection effect of light can be further enhanced. The uneven portion 15 may be formed on the main body layer 11, or may be formed of a layer separate from the main body layer, such as the resin layer 13 and the colored layer 12 described later.

The resin layer 13 may have an ultraviolet curable resin. Since the resin layer 13 constituting the uneven portion 15 has an ultraviolet curable resin, the packaging sheet 10 easily absorbs ultraviolet rays. If the absorbent article 20 in the packaging sheet 10 is excessively irradiated with ultraviolet rays, the absorbent article may be deteriorated or the indicator may react unintentionally. Since the resin layer 13 has the ultraviolet curable resin, it is possible to suppress the influence of ultraviolet rays on the absorbent article 20 packaged in the packaging sheet 10.

The packaging sheet 10 may have a colored layer 12 arranged 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 exert the decorative effect of the colored layer 12. Further, since the main body layer 11 is a substantially smooth surface, the colored layer 12 can be provided in an intended shape such as by making the dot diameter of the colored layer 12 constant, and the packaging sheet 10 can provide the intended decorative effect. Can be demonstrated.

The colored layer 12 may be composed of an aggregate of dots. The standard deviation of the dot diameters constituting the colored layer may be 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 front surface of the packaging sheet may be provided with visibly provided uneven portions 15 and dots of the colored layer 12 located on the back surface side of the uneven portions 15. The colored layer 12 is partially arranged, and a region in which the colored layer 12 is arranged and a region in which the colored layer is not arranged may be provided. The dot diameter is the diameter of the dots in a plan view, and in FIG. 4, the dots are indicated by reference numerals 121 and 122, and the dot diameters are indicated 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 colored layer 12 tends to exert an intended decorative effect. The standard deviation of the dot diameter is an index of the variation of the dot diameter. When the average particle size (diameter in plan view) of 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. Is preferable.

Of the plurality of dots, the standard deviation of the dot diameters constituting the same color may be 10% or less of the average diameter, and more preferably 5% or less of the average diameter. The dots that make up the same color refer to the dots that make up the same color in hue, lightness, and saturation. In FIG. 4, the dot 121 is a dot forming the same color, and the dot 122 is a dot forming the same color. The dots 121 and 122 are dots forming different colors, and their diameters are different. Since the dot diameters constituting the same color are substantially uniform, the coloring effect of the same color can be made uniform, and the intended decorative effect can be more easily exhibited.

The dots of the colored layer 12 may be provided in a region overlapping the concave portion of the uneven portion 15 and a region overlapping 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 the region shown by 15A in FIG. 4, and the region overlapping the convex portion is the region shown by 15B in FIG. The standard deviation between the dot diameter of the region 15A overlapping the concave portion and the dot diameter of the region 15B overlapping the convex portion of the uneven portion is 10% or less of the average diameter, and more preferably 5% or less of the average diameter. You can. More preferably, among the dots in the region 15A overlapping the concave portion, the dot diameters (for example, D121) of the dots constituting the same color are substantially uniform, and among the dots in the region 15B overlapping the convex portion, the same color is formed. The dot diameter (for example, D121) of the dots to be formed 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 decorative effect can be more easily exhibited.

The colored layer 12 may partially overlap with the resin layer 13, and is provided with a region 12A in which the resin layer 13 and the colored layer 12 overlap and a region 12B in which the resin layer 13 and the colored layer 12 do not overlap. 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 arranged, but the main body layer 11 and the resin layer 13 may be arranged. 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 uneven portion 15 in the region 12A where the resin layer 13 and the colored layer 12 overlap and the height of the uneven portion 15 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. Substantially the 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, it is easy to exert the intended decorative effect by the uneven portion of the packaging sheet.

The packaging sheet 10 may be provided with a wearer image 17 showing an image of the wearer and an identification image 16 displaying identification information such as a product name. The wearer image 17 and the identification image 16 may be composed of the colored layer 12. The wearer image 17 is an image for indexing the wear target person, and may include a part of the wear target person's face and body.

The uneven portion 15 may have a plurality of uneven patterns. The plurality of uneven patterns may differ in at least one of the planar shape of the uneven portion, the height of the uneven portion, and the length and width of the uneven portion. The planar shape of the uneven 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 uneven patterns, different decorative effects can be exhibited depending on the plurality of reflection patterns. The light that hits the surface 10T of the packaging sheet 10 has a complicated reflection mode, and the aesthetics can be enhanced. The width of the uneven portion and the interval between the uneven portions may be 2.0 mm or less. The width of the uneven portion is the length in the width direction of the concave portion or the convex portion, and the interval of the uneven portion is the interval between the concave portions or the interval between the convex portions. By arranging fine uneven portions on the surface of the packaging sheet, light is more easily reflected diffusely on the surface of the packaging sheet. Therefore, the decorative effect due to diffused reflection of light can be enhanced, and the intended decorative effect can be exhibited. Preferably, the width of the uneven portion and the interval between the uneven portions may be 0.5 mm or more and 1.0 mm or less, further enhancing the diffused reflection effect of light, and easily exhibiting the intended decorative effect.

FIG. 5 is an enlarged plan view of the C portion of the region overlapping the wearer image. FIG. 6 is a cross-sectional view of the packaging sheet along the DD line shown in FIG. The dot diameter of the colored layer in the region R1 constituting the eyes of the wearer image may be larger than the dot diameter of the colored layer in the region R2 constituting the periphery of the eyes of the wearer image. Therefore, the eyes in the wearer's image become darker and the eyes can be made more conspicuous. The height of the uneven portion 15 of the region R1 constituting the eye may be higher than the height of the uneven 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 uneven portion 15 of the region R1 constituting the eye may be regularly arranged, and the uneven portion 15 in the region R2 forming the periphery of the eye may be irregularly arranged. The region R2 around the eyes is a region constituting the skin, and the irregular shape can give a skin-like texture.

The combination of the uneven portion 15 and the colored layer 12 may exert a complicated decorative effect according to the image. The uneven pattern of the uneven portion overlapping the wearer image and the uneven pattern of the identification image may be different. As the uneven pattern of the wearer's image, an irregular and fine uneven pattern may be adopted to easily generate a skin-like texture. As the uneven pattern of the uneven portion overlapping with the identification image 16, a regular uneven pattern may be adopted so that the identification information can be easily seen. The fine uneven pattern is a pattern in which the width of the uneven portion and the length of the uneven portion are short. Specifically, the width of the uneven portion of the region constituting the skin may be smaller than the width of the uneven portion of the region constituting the other portion (periphery of the skin) of the wearer image. The width of the uneven portion of the area constituting the skin is short, and when the user touches the image of the skin, the texture becomes smooth. The soft texture of the skin image can give a gentle impression to the skin and an absorbent article that touches the skin gives a soft impression. Further, the planar shape of the uneven portion of the region constituting the skin is preferably an ellipse or a rectangle that is not a perfect circle. When the uneven portion is a perfect circle, the uneven portion may exert a visual effect like a pimple, and the elliptical shape or the rectangular shape can give a smooth texture.

As shown in FIGS. 2 and 3, the absorbent articles may be laminated in the thickness direction. The boundary 23 between the absorbent articles may be along the longitudinal direction and the width direction of the absorbent articles. The absorbent article 20 may be made of a flexible material such as a non-woven fabric, and the outer corners of the absorbent article tend to be curved rather than straight. Therefore, the distance D1 between the article surface 22 of the absorbent article arranged so as to face the packaging sheet 10 and the back surface of the packaging sheet 10 is likely to change near 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 inside the packaging sheet 10, and the visual effect when visually recognized from the surface 10T side of the packaging sheet 10 is likely to change. Specifically, since the shadow becomes darker in the deep portion from the packaging sheet 10 to the article surface 22, the brightness of the packaging sheet 10 becomes low. Since the shadow is lightened in the portion where the depth from the packaging sheet 10 to the surface of the article is shallow, the brightness of the packaging sheet 10 is increased. At least one of the uneven portion 15 and the colored layer 12 may be arranged in a region straddling the boundary 23 between the absorbent articles 20. Since the uneven portion 15 is arranged in the region straddling the boundary 23 of the absorbent article 20, the variation in brightness due to the boundary 23 of the absorbent article 20 can be made less noticeable by the decorative effect of the uneven portion 15. Therefore, the intended decorative effect of the packaging sheet can be more exerted. Further, since the colored layer 12 is arranged in the region straddling the boundary 23 between the absorbent articles, the variation in brightness due to the boundary 23 of the absorbent articles can be made less noticeable by the decorative effect of the colored layer 12.

The absorbent article 20 has an article surface 22 that is arranged 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 the E portion shown in FIG. FIG. 6 shows a colored region 21 that is visible through the packaging sheet 10. The colored region 21 may be provided on the exterior sheet itself constituting the outer surface of the absorbent article 20, or may be visibly provided via the exterior sheet. At least one of the uneven portion 15 and the colored layer 12 of the packaging sheet 10 may be arranged 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, it may be difficult for the user to grasp the decorative effect of the packaging sheet 10. The colored region 21 of the absorbent article 20 can be made less noticeable by the decorative effect of the uneven portion 15 or the colored layer 12, and the decorative effect of the packaging sheet 10 can be made more noticeable. Therefore, the intended decorative effect of the packaging sheet 10 can be more exerted.

The colored region 21 may have a plurality of patterns, and the patterns of the colored regions 21 of adjacent absorbent articles may be 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 less noticeable, and the decorative effect of the packaging sheet 10 can be made more 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. The boundary 23 between the absorbent articles tends to be shaded, so that the brightness of the packaging sheet tends to be low. Since the portion of the uneven portion 15 or the colored layer 12 that exerts the decorative effect extends in the direction intersecting the boundary 23 between the absorbent articles, the shadow at the boundary 23 between the absorbent articles can be made less noticeable. Therefore, the intended decorative effect of the packaging sheet can be more exerted.

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

Although the present invention has been described in detail using the above-described embodiments, it is clear to those skilled in the art that the present invention is not limited to the embodiments described in the present specification. The present invention can be implemented as modifications and modifications without departing from the spirit and scope of the present invention as defined by the claims. Therefore, the description herein is for purposes of illustration only and does not have any limiting implications for the present invention.

According to the above aspect, it is possible to provide a package of an absorbent article capable of smoothly taking out the absorbent article while exerting an intended decorative effect by the decoration applied to the packaging sheet.
