[Patent Document 1] Japanese Patent Application Laid-Open No. 2009-536069

In Patent Document 1, by providing a matte layer on the packaging sheet, a decorative effect such as a sense of luxury can be exhibited. However, when embossing is performed on the packaging sheet, irregularities are formed on the front and back surfaces of the packaging sheet. Therefore, there are parts that are easy to print and parts that are not easy to print on the packaging sheet, and print unevenness is likely to occur. There is a possibility that the decorative effect to be exhibited by the decoration applied to the packaging sheet cannot be exhibited due to the occurrence of printed streaks.

Therefore, the packaging body of an absorbent article which can exhibit the decorative effect to be exhibited by the decoration given to a packaging sheet is desired.

(2) Structure of the package of the absorbent article Hereinafter, the package of the absorbent article according to the embodiment will be described with reference to the drawings. In addition, in the following drawing description, the same or similar code|symbol is attached|subjected to the same or similar part. However, the drawings are for schematic display, please note that the ratio of each dimension may be different from the actual one. Therefore, specific dimensions and the like should be determined with reference to the following description. Moreover, the part which differs in the relationship, ratio, etc. of mutual dimensions may be included in each drawing.

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 taken along the line A-A of Fig. 1 . The package 1 of an absorbent article (hereinafter referred to as the package 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 into 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 the present embodiment is a disposable paper diaper, and can be accommodated in the packaging sheet 10 in a state of being 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 part B shown in FIG. 2 . 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 is in contact with the absorbent article 20 .

The packaging sheet 10 has uneven portions 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 reflects light that comes into contact with the surface 10T of the packaging sheet 10 indiscriminately. Through the random reflection of light, it can play a decorative effect. The glossiness of the surface 10T of the packaging sheet 10 is lower than the glossiness of the back surface 10B of the packaging sheet 10 . More preferably, the glossiness of the surface 10T of the packaging sheet 10 is 1/2 times or less the glossiness of the back surface 10B of the packaging sheet 10 . The effect of random reflection of light by the surface 10T of the packaging sheet 10 can be obtained more ideally. The more light is reflected by the surface of the packaging sheet, the less visible the absorbent article inside the packaging sheet becomes. Therefore, by wrapping the sheet, the decorative effect to be presented is easy to be exhibited. The gloss can be measured by the gloss meter VG7000 of Nippon Denshoku Industries Co., Ltd. by the measuring method according to the specular gloss measuring method (JIS 8741), and is the gloss at an angle of 60°.

The back surface 10B of the packaging sheet 10 is smoother than the surface 10T of the packaging sheet 10 . As an index for comparing the smoothness of the sheet, for example, the height of the unevenness of the surface, the standard deviation (SMD) of the surface roughness of the surface KES, the mean deviation (MMD) of the mean friction coefficient, etc. are mentioned. 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 that of 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, since the shape of the unevenness on the surface opposite to the measurement surface has an influence, it is preferable to take out and measure only the layer constituting the surface to be measured. Since the back surface of the packaging sheet is smoother than the surface of the packaging sheet, frictional resistance when the absorbent article is taken out can be suppressed. When taking out the absorbent article, the absorbent article is not easily hooked to the back of the packaging sheet, and the user can easily take out the absorbent article smoothly. Since the surface of the packaging sheet has irregularities and the back of the packaging sheet is smooth, the decorative effect to be exhibited by the irregularities on the surface of the packaging sheet can be exhibited, and the absorbent article can be smoothly taken out during use.

The packaging sheet 10 has the main body layer 11 arranged on the back side of the uneven portion 15 . The body layer 11 is arranged on the back surface of the packaging sheet. The body layer 11 is formed of a thin film with 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 the KES on the back surface of the bulk layer 11 is 0.8 or less, more preferably 0.2 or more and 0.3 or less. The mean deviation (MMD) of the surface friction coefficient of KES on the back surface of the bulk layer is 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 is 10% or less of the average thickness of the body layer 11 . In addition, the surface of the bulk layer 11 is substantially smooth like the back surface of the bulk layer 11 . Since the surface of the main body layer 11 is substantially smooth, when the coloring layer 12 and the resin layer 13 are formed on the surface side of the main body layer 11 , it is difficult to generate streaks. Therefore, the coloring layer 12 and the resin layer 13 can be easily formed in the desired form, and the desired decorative effect can be exhibited by random reflection of light, coloring, and the like.

Since the back surface of the main body layer 11 is substantially smooth, when the main body layer 11 is subjected to decorative processing such as formation of the concave and convex portions 15 , processing unevenness is less likely to occur. Therefore, the concavo-convex portion 15 can be processed on the main body layer 11 in the desired form, and the desired decorative effect can be easily exhibited by the concave-convex portion 15 . In addition, the back surface 10B of the packaging sheet 10 may be constituted by the back surface of the main body layer 11, and the back surface 10B of the packaging sheet 10 may be substantially smooth.

The mean deviation (MMD) of the surface friction coefficient and the mean deviation (SMD) of the surface roughness can be measured based on the Kato Technology Co., Ltd. product, which is generally known as a characteristic value indicating the feel of the surface of the sheet. The characteristic value of KES (Reference: Standardization and Analysis of Tactile Evaluation (Second Edition), published by author Yoshio Kawabata on July 10, 1955) was measured.

Specifically, the measurement of the surface properties was performed using KES-FB4 manufactured by Kato Technology Co., Ltd., using the range of 1.0×1.0 cm for each sample as a sample, and arranging it on a flat metal flat test bench. To measure the surface roughness, put a load of 10gf on the surface (or back), and crimp a contact terminal with a width of 0.5cm wound around a piano wire with a diameter of 0.5mm to the sample, and then measure the surface friction. , which is performed by arranging 10 piano wires that are the same as the contact terminals used for the measurement of surface roughness, and then crimping the contact surface to the sample by a plumb bob with a force of 50 fg. In the measurement of surface friction and surface roughness, the sample was moved horizontally by 2 cm at a constant speed of 0.1 cm/sec, and a uniaxial tension of 20 gf/cm was applied to the sample. From the measurement results, the mean deviation (MMD) of the surface friction coefficient and the mean deviation (SMD) of the surface roughness were obtained.

The thickness of the bulk layer 11 can be measured by the following method. After the body layer 11 was subjected to humidity conditioning at 23°C x 50% RH for 2 hours, the reference direction (0° direction) was specified with an arbitrary point A of the body layer 11 as the center, and the reference direction (0° direction) was specified from the center point A. a), clockwise 45 degrees to the reference direction (b), 90 degrees (c), 135 degrees (d), 180 degrees (e), 225 degrees (f), 270 degrees (g) and A total of 8 straight lines L1~L8 of 100mm are drawn in the 8 directions of the 315-degree direction (h). On the respective straight lines, measurement was performed with a length meter "HEIDENHAIN-METRO MT1287" (manufactured by HEIDENHAIN) at intervals of 10 mm from the center point (measured at 10 points). Then, the average value of the measured values at a total of 80 points of data obtained by measuring all the straight lines was calculated, and this was taken as the average thickness, and the standard deviation value with respect to the average thickness was calculated.

In addition, the bending rigidity of the packaging sheet 10 may be 0.07×10 ⁻⁴ Nm/m or more, and the bending strength of the packaging sheet 10 may be 53.0 mm or more. Since the flexural rigidity of the packaging sheet 10 is 0.07×10 ⁻⁴ N or more, the flexural strength of the packaging sheet 10 is 53.0 mm or more, and the packaging sheet has toughness, it is difficult to produce irregularities in decorative processing such as formation of the uneven portion 15 . Therefore, the concavo-convex portion 15 can be processed on the main body layer 11 in the desired form, and the desired decorative effect can be easily exhibited by the concave-convex portion 15 .

The bending strength of the packaging sheet 10 was measured according to JIS L 1913 6.7.3. More specifically, 5 test pieces of 38 mm×25 mm were collected, and were continuously measured from the front and back of the test pieces with a Gurley tester (Bending Strength Tester No. 311 manufactured by Yasuda Seiki Co., Ltd.). The average value of the front and back surfaces obtained was used to calculate the flexural strength.

The flexural rigidity of the packaging sheet 10 was measured using KES FB-2 manufactured by Kato Technology Co., Ltd. A test piece having a size of 50 mm×100 mm was prepared, one end of the test piece in the longitudinal direction was held by one of a pair of jigs, and the other end in the longitudinal direction of the test piece was held by the other jig. One jig was rotated around the other jig, and the bending rigidity of the test piece thus folded was measured with a torque detector. Five sets of test pieces were prepared, and the average value of the measured values was taken as the bending rigidity.

The concavo-convex portion 15 is constituted by the resin layer 13 disposed on the surface side of the body layer 11 . The resin layer 13 is hardened by predetermined processing (temperature adjustment, ultraviolet irradiation). Therefore, the desired shape of the concavo-convex portion 15 can be easily realized. Therefore, by increasing the height of the concave-convex portion 15 to improve the reflection effect, or by making the height of the concave-convex portion 15 partially different to make the reflection pattern partially different, the concave-convex portion 15 of the packaging sheet 10 can easily exhibit the desired decorative effect. The height H15 of the concave-convex portion 15 is the distance in the thickness direction between the vertex of the convex portion and the bottom surface of the concave portion (see FIG. 6 ). The height of the uneven portion 15 is 0.8 μm or more. The height of the uneven portion 15 is desirably 1.2 μm or more, and more desirably 1.5 μm or more. By setting the height of the concavo-convex portion to be 0.8 μm or more, the effect of randomly reflecting light that has touched the surface of the packaging sheet can be more ideally obtained. In addition, the height of the uneven portion is preferably 1.2 μm or more, and more preferably 1.5 μm or more, whereby the effect of random reflection of light can be further enhanced. In addition, the concave-convex portion 15 may be formed in the body layer 11, or may be constituted by other layers different from the body layer, such as the resin layer 13 and the coloring layer 12 described later.

The resin layer 13 has ultraviolet curable resin. Since the resin layer 13 constituting the concavo-convex portion 15 has an ultraviolet curing resin, the packaging sheet 10 can easily absorb ultraviolet rays. When ultraviolet rays are irradiated to the absorbent article 20 in the packaging sheet 10 excessively, the absorbent article may be deteriorated or the indicator may react unintentionally. Therefore, since the resin layer 13 has the ultraviolet curable resin, the absorbent article 20 packaged by the packaging sheet 10 can be suppressed from being affected by the ultraviolet rays.

The packaging sheet 10 has a coloring layer 12 disposed between the 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 . In addition, since the main body layer 11 is a substantially smooth surface, the dot diameter of the colored layer 12 can be made constant, so that the colored layer 12 can be designed in the shape to be presented, and the decorative effect to be presented can be exhibited by the packaging sheet 10 .

The colored layer 12 may be constituted by an aggregate of dots. The standard deviation of the dot diameter constituting the coloring layer is 10% or less of the average diameter, 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 is identifiably provided with the concave-convex portion 15 and the dots of the colored layer 12 located on the back side rather than the concave-convex portion 15 . The colored layer 12 may be partially arranged, and a region where the colored layer 12 is arranged and a region where the colored layer is not arranged are provided. The dot diameter is the diameter of a point on a plane viewing angle. In FIG. 4, the dots are indicated by symbols 121 and 122, and the dot diameters are indicated by D121 and D122. Since the standard deviation of the spot diameter is 10% or less of the average diameter, the spot diameters are substantially equal. Therefore, streaks of the colored layer 12 are not easily generated, and the desired decorative effect can be easily exhibited by the colored layer 12 . The standard deviation of the spot diameter is an indicator of the distribution of spot diameters. When the average particle diameter (diameter of the plane viewing angle) of the dots is x and the standard deviation is σ, the distribution of particle diameters represented by σ/x is 10% or less, more preferably 5% or less.

Among a plurality of dots, the standard deviation of the dot diameters constituting the same color is 10% or less of the average diameter, more preferably 5% or less of the average diameter. Points that form the same color refer to points that form the same color in hue, lightness, and chroma. In FIG. 4 , the dots 121 are dots that form the same color, and the dots 122 are dots that form the same color. The dots 121 and 122 are dots of different colors and have different diameters. Since the diameters of the dots constituting the same color are substantially equal, the coloring effect of the same color can be equalized, and the desired decorative effect can be more easily exhibited.

The dots of the colored layer 12 can be provided in the region overlapping with the concave portion of the concave-convex portion 15 and the region overlapping with the convex portion. Furthermore, the boundary between the concave portion and the convex portion may be used as an intermediate point in the thickness direction between the apex of the convex portion and the bottom surface of the concave portion. The area|region which overlaps with a recessed part is the area|region shown by the code|symbol 15A of FIG. 4, and the area|region which overlaps with a convex part is the area|region shown by the code|symbol 15B of FIG. The standard deviation of the spot diameter of the region 15A overlapping the concave portion and the spot diameter of the region 15B overlapping the convex portion of the uneven portion is 10% or less of the average diameter, more preferably 5% or less of the average diameter. More preferably, the dot diameters (eg D121 ) of the dots forming the same color are substantially equal in the dots of the area 15A overlapping the concave portion, and the dots forming the dots of the same color among the dots of the area 15B overlapping the convex portion The diameters (eg D121) are substantially equal. Since the dot diameter of the region overlapping with the concave portion and the dot diameter of the region overlapping the convex portion are substantially equal, the coloring effect can be equalized, and the desired decorative 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 overlaps with the colored layer 12 and a region 12B where the resin layer 13 does not overlap with the colored layer 12 may be provided. In the region 12B where the resin layer 13 and the colored layer 12 do not overlap, the colored layer 12 is not disposed, but the body layer 11 and the resin layer 13 are disposed. The difference between the height of the concavo-convex portion 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 12B where the resin layer 13 does not overlap the colored layer 12 is 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 coloring layer 12 overlap, and the height of the concavo-convex portion in the region where the resin layer 13 does not overlap the coloring layer 12, the resin layer and the coloring layer are overlapped with each other. The area and the area where the resin layer and the coloring layer do not overlap can exhibit substantially the same light reflection effect. Therefore, the desired decorative effect can be easily exhibited by the concave-convex portion of the packaging sheet.

The packaging sheet 10 is provided with a wearer image 17 that displays 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 formed by the colored layer 12 . The wearer image 17 is an image for indicating the wearer, and includes a face and a part of the body of the wearer.

The concavo-convex portion 15 may have a plurality of concavo-convex patterns. The plurality of concave-convex patterns differ in at least one of the planar shape of the concave-convex portion, the height of the concave-convex portion, and the length and width of the concave-convex portion. The plane shape of the concave-convex portion is the shape of the concave portion or the convex portion in the plane viewing angle, and includes a rectangle, a circle, and a triangle. Due to the plurality of concave-convex patterns, different decorative effects can be exerted by the plurality of reflection patterns. The light contacting the surface 10T of the packaging sheet 10 is formed in a complex reflection form, and the aesthetics can be improved. The width of the concavo-convex portion and the interval of the concave-convex portion may be 2.0 mm or less. The width of the concave-convex portion is the length in the width direction of the concave portion or the convex portion, and the interval of the concave-convex portion is the interval between the concave portions or the interval between the convex portions. The fine unevenness|corrugation part is arrange|positioned on the surface of a packaging sheet, and it becomes easy to reflect light indiscriminately on the surface of a packaging sheet. Therefore, the decorative effect by the random reflection of light can be improved, and the desired decorative effect can be exhibited. Ideally, the width of the concave-convex portion and the interval between the concave-convex portions are 0.5 mm or more and 1.0 mm or less, so that the effect of random reflection of light can be further improved, and the desired decorative effect can be easily exhibited.

Figure 5 is an enlarged plan view of portion C of the area overlapping the image of the wearer. FIG. 6 is a cross-sectional view of the packaging sheet along the line D-D as shown in FIG. 5. FIG. The dot diameter of the coloring layer in the region R1 constituting the eye of the wearer's image is larger than the dot diameter of the coloring layer in the region R2 around the eye constituting the wearer's image. Therefore, the eyes of the wearer's image are darkened, and the eyes can be made conspicuous. The height of the uneven portion 15 of the region R1 constituting the eye portion is higher than the height of the uneven portion 15 of the region R2 constituting the periphery of the eye portion. The reflection effect of the region R1 constituting the eye can be enhanced, and the eye can be made conspicuous. The concavo-convex portions 15 of the region R1 constituting the eye portion may be regularly arranged, and the concave and convex portions 15 of the region R2 constituting the periphery of the eye portion may be irregularly arranged. The area R2 around the eyes is an area that constitutes the skin, and the irregular shape can give a skin-like texture.

By the combination of the concave-convex portion 15 and the coloring layer 12, it is possible to exert a complex decorative effect in accordance with the image. The concavo-convex pattern of the concavo-convex portion overlapping the wearer's image may be different from the concavo-convex pattern of the identification image. The concave-convex pattern of the wearer's image adopts an irregular and fine concave-convex pattern, which is easy to produce a skin-like texture. The concave-convex pattern of the concave-convex portion overlapping the identification image 16 adopts a regular concave-convex pattern, which constitutes the identification information that is easy to see. In addition, the thin concavo-convex pattern is a pattern in which the width of the concavo-convex portion and the length of the concave-convex portion are short. Specifically, the width of the concavo-convex portion in the region constituting the skin is narrower than the width of the concave-convex portion in the region constituting the other part of the wearer's image (surroundings of the skin). The width of the concavities and convexities of the area constituting the skin is narrow, so that a slippery texture is obtained when the user touches the image of the skin. By the soft texture of the skin image, it is possible to give a skin-friendly impression, an impression that an absorbent article in contact with the skin is soft, and the like. Moreover, it is preferable that the planar shape of the uneven|corrugated part of the area|region which comprises the skin is an ellipse, a rectangle, etc. which are not a perfect circle. If the concave-convex part is perfectly circular, the concave-convex part will have a visual effect like a pimple, and a smooth texture can be imparted by an oval shape, a rectangular shape, or the like.

As shown in FIGS. 2 and 3 , the absorbent articles are laminated in the thickness direction. The boundary 23 between absorbent articles is along the longitudinal direction and the width direction of the absorbent articles. The absorbent article 20 is made of a flexible material such as non-woven fabric, and the corners of the outer shape of the absorbent article tend to be curved rather than straight. 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 easily changed in the vicinity of the boundary 23 of the absorbent article 20 . If the depth from the packaging sheet 10 to the article surface 22 is changed, a shadow is generated inside the packaging sheet 10, and the visual effect when viewed from the surface 10T side of the packaging sheet 10 is easily changed. Specifically, since the shadow becomes deep in the part where the depth from the packaging sheet 10 to the article surface 22 is deep, the lightness of the packaging sheet 10 is lowered. The lightness of the packaging sheet 10 becomes high because the shadow becomes lighter in the portion where the depth from the packaging sheet 10 to the surface of the article is shallow. At least one of the uneven portion 15 and the colored layer 12 may be arranged in a region spanning the boundary 23 of the absorbent articles 20 . By arranging the uneven portion 15 in the region spanning the boundary 23 of the absorbent article 20 , the decorative effect of the uneven portion 15 can be utilized to make the distribution of lightness in the boundary 23 of the absorbent article 20 inconspicuous. Therefore, the decorative effect of the packaging sheet to be presented can be further exerted. Moreover, by arranging the colored layer 12 in the region spanning the boundary 23 of the absorbent articles, the decorative effect of the colored layer 12 can be utilized, and the distribution of the brightness of the boundary 23 of the absorbent articles can be made inconspicuous.

The absorbent article 20 has an article surface 22 disposed opposite the packaging sheet 10 . On the surface 22 of the article, a colored area 21 may also be provided. FIG. 6 is an enlarged plan view of the portion E shown in FIG. 1. FIG. In FIG. 6, the colored area 21 which can be recognized by the packaging sheet 10 is shown. The colored region 21 may be provided on the outer sheet itself constituting the outer surface of the absorbent article 20, or may be provided so as to be identified through the outer sheet. At least one of the uneven portion 15 of the packaging sheet 10 and the colored layer 12 may be arranged in a region overlapping the colored region 21 . If the colored area 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 . Due to the decorative effect of the uneven portion 15 or the colored layer 12, the colored region 21 of the absorbent article 20 is made inconspicuous, and the decorative effect of the packaging sheet 10 can be made conspicuous. Therefore, the decorative effect of the packaging sheet 10 to be presented can be further exerted.

The colored regions 21 may be configured to have a plurality of patterns, and the patterns of the colored regions 21 of adjacent absorbent articles may be different. When the colored area 21 has a plurality of patterns, the decorative effect of each pattern can be exhibited, and the colored area of the absorbent article 20 can be more conspicuous. With the decorative effect of the packaging sheet 10, the colored area 21 of the absorbent article 20 becomes inconspicuous, and the decorative effect of the packaging sheet 10 can be made conspicuous.

As shown in FIG. 6 , at least one of the uneven portion 15 and the colored layer of the packaging sheet 10 extends in a direction intersecting the direction in which the opposite boundary 23 extends. The lightness of the packaging sheet tends to be lowered because shadows tend to occur at the boundaries 23 of the absorbent articles. Since the part to exhibit the decorative effect by the uneven part 15 or the colored layer 12 extends in the direction intersecting the boundary 23 of the absorbent articles, the shadow of the boundary 23 of the absorbent articles can be made inconspicuous. Therefore, the decorative effect of the packaging sheet to be presented can be further exerted.

Next, the package of the absorbent article concerning other embodiment is demonstrated. The packaging sheet of the packaging body of the absorbent article of other embodiments may not have the body layer 11 . The colored layer 12 of the packaging sheet can also serve as the body layer 11 . In addition, the packaging sheet may not have the colored layer 12 .
