The release treatment agent may, for example, be an anthracene resin, a fluorine resin, or an octadecyl isocyanate resin.

The surface 72 of the packaging sheet 70 is a surface on the outer side when the absorbent article 1 is wrapped by the packaging sheet 70, and is visible on the surface of Figs. 2 and 3. On the surface 72 of the packaging sheet 70, printing is applied. Fig. 5 is a partial enlarged view of a portion B of Fig. 3. The packaging sheet 70 is provided with a first colored region A11 colored by the first color, a first non-colored region A12 not colored by the first color, and a second colored region A2 colored by the second color; a non-colored area A3 of any color of the color and the second color; and an overlapping area A4 colored by the first color and colored by the second color.

The first colored region A11 is provided on the entire packaging sheet 70, and constitutes a non-display element portion 62 that is a background of the display element portion 61 formed by the pattern. The non-display element portion 62 is a portion other than the display element having the pattern pattern or the character. The first non-colored area A12 is a display element portion 61 that constitutes a star pattern and a heart pattern. The second colored area A2 is printed by a second color different from the first color. The second colored area A2 is a display element portion 61 that constitutes a star pattern and a heart pattern. The first non-colored area A12 and the second colored area A2 have the same shape, and are arranged to overlap each other.

The display element unit 61 is a feature and a use that can represent the display element including the pattern pattern and the character, and can indicate the performance and the like of the absorbent article 1. The user can grasp the performance of the absorbent article 1 from the outside of the packaging sheet 70 when the absorbent article 1 is used and when the absorbent article 1 is used. In addition, depending on the content of the display element of the display element unit 61 (the impression or meaning of the pattern), the performance of the absorbent article or the like may be configured, and the performance of the absorbent article may be configured depending on the content and color of the display element. .

In this way, the packaging sheet is decorated by pattern patterns and colors, and By arranging the performance of the absorbent article by the decoration, the absorbent article 1 is stored in a state where it is taken out from the storage bag 201 (see FIG. 8) to be described later, or is taken out from the storage bag 201. When the absorbent article 1 is worn, the user can see the display elements of the packaging sheet 70 in a state in which the absorbent article 1 is wrapped in the packaging sheet 70, and whether or not the absorbent article such as an absorbent article for the daytime is grasped. Absorption performance and selection. Moreover, compared with the case of using a character or the like, since it is known that it is a sanitary napkin, it is suitable when it is not desired to recognize the content.

A non-colored area A3 and an overlapping area A4 are provided around the second colored area A2. The non-colored area A3 is an area that is not colored, and shows the color of the packaging sheet 70 itself. The non-colored area A3 is arranged along the outline of the second colored area A2. The overlap region A4 is a region in which the first color and the second color overlap, and is formed thicker than the first color and thicker than the second color.

In this manner, the non-colored region A3 is disposed along the contour of the second colored region A2, whereby the color of the first colored region A11 and the second colored region A2 and the non-colored region A3 are compared. 1 The colored area A11 and the second colored area A2 appear conspicuous, and the display elements can be expressed in a three-dimensional manner. Further, by arranging the overlapping area A4 along the outline of the second colored area A2, the outline of the second colored area A2 can be deepened, and the contrast can be expressed by the contrast of the colors, and the display elements forming the three-dimensional shape can be formed.

By displaying the elements in a three-dimensional manner, the texture of the packaging sheet 70 itself is improved, and the package 100 of the absorbent article can be seen in a packaged state. Come like a handkerchief and other cloth. In addition, the embossing process for three-dimensional decoration of the packaging sheet itself is not performed, but the three-dimensional display element is expressed by the contrast of the colors. Therefore, it is possible to suppress the occurrence of defects due to peeling of the adhesive or the like.

As shown in FIG. 3, the first non-colored region A12 is provided at the center in the width direction W of the absorbent article 1 and at both ends in the width direction W of the absorbent article 1. The second colored region A2 is partially overlapped with the first non-colored region A12 located at the center in the width direction W, and is not disposed to overlap the first non-colored region located at both end portions in the width direction W. A12. In other words, the first non-colored area A12 located at both end portions in the width direction is not colored by the second color, and becomes the non-colored area A3. The first non-colored area A12 positioned at the center in the width direction and the first non-colored area A12 positioned at both end portions in the width direction are different. Therefore, the decorative patterns of the plurality of first non-colored regions can be made different, and the decorative property can be improved.

The overlapping area A4 and the first non-colored area A12 are sandwiched by the second colored area A2 in the longitudinal direction L. The overlapping area A4 and the non-colored area A3 are disposed at both end portions in the longitudinal direction L of the second colored region A2. The overlapping area A4 is provided at the end on the opposite side of the non-colored area A3. By providing the overlapping area A4 and the non-colored area A3 in this manner, the color of one end portion of the second colored area A2 can be made lighter, the color of the other end portion can be made thicker, and the entire display element can be shaded. The display elements can be expressed more stereoscopically.

The color that is colored on the packaging sheet can also be based, for example, on a Japanese special watch. The Commission Internationale de l’Eclairage L*a*b* color space (hereinafter referred to as "CIELab") described in 2008-507385 is suitable. CIELab is a mathematical tristimulus color scale based on the CIE 1976 benchmark. CIELab is able to record colors quantitatively and correctly. CIELab is a 3-dimensional space that can plot colors in xyz space like Cartesian coordinates. CIELab is in the xyz space of Cartesian coordinates, which is originally the x-axis, but has a green to red color. CIELab uses the axis as the a-axis. A negative a* value indicates green, and a positive a* value indicates red. CIELab is in the xyz space of Cartesian coordinates, originally y-axis, but has a blue to yellow color. CIELab is the axis as the b axis. A negative b* value indicates blue, and a positive b* value indicates yellow. CIELab is in the xyz space of Cartesian coordinates, which is also the z-axis, but has brightness. CIELab means that the axis is regarded as the L axis. The L* axis is a range of 100 to 0, 100 is white, and 0 is black. The L* value of 50 indicates the gray in the middle (however, it is a case where the conditions of a* and b* are 0). According to 3 values (L*, a*, b*), any color can be illustrated in CIELab.

The three-dimensional CIELab is a component that can calculate three colors of chroma, hue, and brightness. The components of the hue and chroma are determined in the space of the 2nd dimension formed by the a-axis and the b-axis. Chroma is the relative saturation of the perceived color; and the a*b* plane is determined by the distance from the origin of the measurement.

For example, a color indicating a value of a*b* (10, 0) is lower than a color having a value of a*b* (20, 0). And it is a qualitative perception that the subsequent color is redder than the previous color. Hue, is a specific color Relative red, yellow, green, and blue. The radius from the origin to any color can be made in a 2-dimensional a*b* space. The hue is the angle measured from 0° (positive a* axis) to the radius made. The hue can be any value from 0° to 360°. Brightness is determined by the value of L*, and higher values are whiter and lower values are darker.

The color difference ΔE having a different color can be obtained, for example, by the following equation. △ E = ((ΔL *) 2 power + (△ a *) 2 power + (△ b *) 2 power) 1/2 power. Here, L is the brightness, a* is the coordinate of the red-green axis, and b* is the coordinate of the yellow-blue axis. By measuring the chromatic aberration with respect to the reference color, the colors of the first color and the second color which are printed on the packaging sheet or the like can be specified.

The color difference is, for example, measured by the following method. Specifically, first, a white color L*a*b* which becomes a reference color is measured using a color difference measuring device (for example, CR-300 manufactured by Konica Minolta Co., Ltd.). In the embodiment of the present embodiment, a C light source (Specification of the International Commission on Illumination (CIE)) is used as a light source of the measuring device. The diameter of the measuring window of the measuring machine is 10 mm. Further, a white reference plate (Y92.0 x 0.3145 y0.3198) was used as a reference color for measuring chromatic aberration. Further, here, Y is a value of a bright index, and x and y are plane coordinates of chromaticity.

Next, the measured value (L*a*b*) is set as the reference color. Next, a packaging sheet or the like (a measurement target of chromatic aberration) to be a sample is placed on a white reference plate, and L*a*b* of the color to be measured is measured. Thereby, the chromatic aberration of the measurement target with respect to the reference color can be calculated. In addition, if the color portion of the sample to be measured is smaller than the measurement window of the measuring machine, the part that is to be cut out in advance is prepared in advance, and the gap is not overlapped. The method is juxtaposed on a white reference plate for measurement.

The color difference ΔE between the first color and the second color is preferably large in order to improve the visibility of the display element, and specifically, it is preferably 1 or more. When the color difference between the first color and the second color is 1 or more, the user can generally recognize the first color and the second color. Further, it is preferable that the color difference ΔE of the first color and the second color is 10 or more. When the color difference between the first color and the second color is 10 or more, the user can more clearly recognize the first color and the second color, and by the combination of the first color and the second color, the display element can be more stereoscopically displayed. .

The first color and the second color are ideal for the complementary color. The relationship of the complementary colors in the form of the present embodiment means a color in which the hue is in the range of 180 ± 45 degrees. Ideally, when the range is within ±15 degrees, it is easy to become dark when overlapping colors. Specifically, for example, green with respect to red; orange with respect to blue; a combination of such purple with respect to yellow.

The area of the overlap region A4 is preferably 1% to 50% with respect to the area of the second colored region A2. By providing the overlapping area A4 of such a range, the outline of the display element is highlighted, and the three-dimensional feeling can be made particularly clear. Further, it is preferable that the area of the overlapping region A4 is preferably 10% to 33% with respect to the area of the second colored region A2. Further, the area of the non-colored region A3 is preferably 1% to 50% with respect to the area of the second colored region A2. By providing the non-colored area A3 of such a range, the stereoscopic feeling of the display element can be made particularly clear. Further, it is preferable that the area of the non-colored region A3 is preferably 10% to 33% with respect to the area of the second colored region A2.

In the embodiment of the present embodiment, as shown in FIG. 4, the first color is superposed on the first color. There is a second color. At least the second color of the first color and the second color is configured to have light transparency. When the second color has light transmittance, when the first color and the second color overlap, the second color and the first color of the lower layer may appear to be mixed. Further, the brightness of the second color is lower than the brightness of the first color. When the luminance of the second color is low, when the first color and the second color are overlapped, the second color and the first color of the lower layer can easily appear to be mixed.

The coloring of the packaging sheet 70 can be applied in accordance with well-known various coloring techniques. The coloring may be, for example, printing, coating, or dipping, but is not limited thereto. The printing method may, for example, be relief printing, flexographic printing, gravure printing, lithography, screen printing, and inkjet, but is not limited thereto.

The absorbent article 1 and the packaging sheet 70 are folded at a predetermined bending position along the width direction W and the longitudinal direction L so that the surface sheet 10 of the absorbent article 1 is inside. Specifically, the packaging sheet 70 is folded via the long side creases FL1 and FL2 along the longitudinal direction L, and is folded via the wide creases FW1 and FW2 along the width direction W. The long side crease and the wide crease are indicated by a dotted line in FIGS. 1 and 2. In the state in which the absorbent article 1 is folded, one of the longitudinal direction L of the packaging sheet 70 is adhered to the packaging sheet 70. The end of the packaging sheet 70 is adhered to a portion of the packaging sheet 70 by an adhesive tape 75. The material for forming the adhesive tape 75 is formed of a single-layer film such as a polypropylene film or a polyethylene film, or a multilayer film in which a plurality of resin films are laminated.

Next, a method of folding the package 100 of the absorbent article will be described. Figure 6 is a diagram showing the folding work of the package 100 of the absorbent article. Body map. The folding work of the package 100 of the absorbent article includes: an absorbent article mounting project; a first folding project; a second folding project; a joining process; and a third folding project.

In the absorbent article mounting work, the absorbent article 1 is placed on the packaging sheet 70. The packaging sheet 70 is opposed to the inner sheet 20 of the absorbent article 1. Further, the absorbent article 1 may be disposed on the packaging sheet 70 that individually packs the size of one absorbent article 1. For example, a plurality of absorptions spaced apart by a predetermined interval may be disposed on the packaging sheet that is continuous along the conveying direction. Sexual items. In the present embodiment, a description will be given of a folding method using a package in which an absorbent article for packaging one absorbent article is used.

In the first folding process, as shown in FIG. 6(a), the packaging sheet 70 and the absorbent article 1 are based on the first long side crease (see FIG. 1) FL1 along the longitudinal direction L, and include the width direction W. The end portion side of one end side of the absorbent article 1 is folded back toward the inside. In the second folding process, as shown in FIG. 6(b), the packaging sheet 70 and the absorbent article 1 are based on the second wide crease FL2 (see FIG. 1) along the longitudinal direction L, and include the width direction W. The other end portion side end portion side of the absorbent article 1 is folded back toward the inside.

Next, the joining process is the end portion in the width direction of the absorbent article 1 and the packaging sheet 70 which are folded back based on the second long side crease FL2 on the packaging sheet 70 via the hot-melt adhesive. According to the present process, the absorbent article 1 is individually packaged by the packaging sheet 70. The hot-melt adhesive may be disposed so that the wide end portion of the inner surface 71 of the packaging sheet can be attached to the surface 72 of the packaging sheet.

Further, in the present embodiment, the end portion in the width direction of the packaging sheet 70 which is folded back based on the first long side crease FL1 and the second long side crease FL2 via the hot-melt type adhesive may or may not be used. The end portion of the sheet 70 in the width direction is then packaged. Further, the method of attaching the end portions in the width direction of the packaging sheet 70 may be followed by heat fusion, pressing or ultrasonic welding.

In the third folding process, as shown in FIG. 6(c), the packaging sheet 70 and the absorbent article 1 have the first wide crease FW1 and the second wide crease FW2 along the width direction W (refer to FIG. 1). The base point is folded back from the both end sides in the longitudinal direction of the absorbent article 1. By performing the above-described work, the package 100 of the absorbent article is folded and miniaturized.

In addition, when the packaging sheet 70 and the absorbent article 1 are folded back from the both end portions of the absorbent article 1 in the longitudinal direction L, one of the end portions of the longitudinal direction L may be folded back, or may be configured. Both sides are folded back one at a time from the both end sides in the longitudinal direction L.

By such folding, the absorbent article 1 can be individually packaged by the packaging sheet 70. When the absorbent article 1 is miniaturized and stored in a bag such as a small storage bag or a handbag, the storage space of the bag is not greatly occupied, and it can be easily carried. In addition, the absorbent article 1 can be individually packaged in a small size, and when it is carried in a toilet or the like during use, it can be placed in the hand without being folded back, and can be kept from being seen by others.

As shown in FIG. 3, the display element portion 61 located at the center in the width direction of the packaging sheet 70 is composed of the first non-colored region A12 and the second colored region A2 (for example, a star pattern), and is positioned at the first long side. Crease FL1 and 2nd long crease between. Moreover, the display element portion 61 located at both end portions in the width direction of the packaging sheet 70 is composed of the first non-colored region A12 and the second colored region A2 (for example, a heart pattern), and is smaller than the first long-side crease FL1. Further, it is located outside the width direction or outside the width direction of the second long side crease FL2.

Therefore, in a state in which the packaging sheet and the absorbent article are folded along the first long side crease or in a state in which the packaging sheet and the absorbent article are folded along the second long side crease, the first long crease is formed to be visible. And the second long side crease is further in the state of the display element portion on the outer side in the width direction. This display element portion is composed of a first non-colored area.
