Utility Model Registration No. 3205937 JP 2019-26295 A

As described above, absorbent article packages are sold in a state in which a plurality of individually packaged absorbent articles are housed in one packaging bag. Since the individually packaged absorbent article is almost invisible, the thickness of each individually packaged absorbent article can be determined by opening the packaging bag and removing the individually packaged absorbent article inside after purchase. You can't really tell unless you take it out. Therefore, when judging the thickness of the individually packaged absorbent article inside, the user relies on the information of the individually packaged absorbent article seen through a transparent window provided in a part of the packaging bag.

However, in the conventional absorbent article package 50, as shown in FIG. 13, the portion of the individually packaged absorbent article 51 facing through the window 52 is composed of a single color. The boundary between 51 and 51 was difficult to understand, and it was not possible to recognize how thick the individually packaged absorbent article 51 was at a glance.

In Patent Document 1, the performance characteristics of the absorbent article can be recognized by the color applied to the fastening tape. It's not clear.

Further, in the case described in Patent Document 2, since the mark provided in the window portion extends along the boundary between the absorbent articles, the individually packaged absorbent article stored inside is marked by the mark. However, since the mark is provided on the packaging bag, there is a risk that the boundary between the mark provided on the packaging bag and the actual individual absorbent article may be misaligned. However, if there is even a slight deviation, it is difficult to determine at a glance how much the individual packaged absorbent article is actually thick. That is, when the mark portion and the boundary between the individually packaged absorbent articles are misaligned, the actual boundary line between the individually packaged absorbent articles can be seen between the adjacent marked portions when viewed closely. It is difficult to recognize the thickness of the individual-packaged absorbent article, and there is a risk of misidentification as being thinner than the actual thickness of the individually-packaged absorbent article.

FIG.

BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

As shown in FIGS. 1 and 2, the package 20 of the sanitary napkin 1 according to the present invention is a packaging bag containing the individually packaged sanitary napkin N in which the sanitary napkin 1 and the individually packaged sheet 10 are folded small in the longitudinal direction. 21 is configured by housing a plurality of them.

[Packaging bag 21]
As shown in FIG. 1, the packaging bag 21 is formed in a substantially rectangular parallelepiped shape having a top surface portion 21A, a bottom surface portion 21B, a front surface portion 21C, a rear surface portion 21D and a pair of side surface portions 21E, 21E. A plurality of individually packaged sanitary napkins N can be stored inside. The front portion 21C is a surface that faces the front when the package 20 is arranged on a display shelf, and is the surface that is most visible to the purchaser. The term “substantially rectangular parallelepiped shape” is not limited to a rectangular parallelepiped in which connecting sides between adjacent faces are formed by clear straight lines, but also includes a rectangular parallelepiped as a whole. For example, it also includes those in which each side connecting each face and each vertex are slightly rounded.

In this specification, unless otherwise specified, the "vertical direction" is the direction connecting the upper surface portion 21A and the bottom surface portion 21B, and the "front-rear direction" is the direction connecting the front surface portion 21C and the rear surface portion 21D. The "horizontal direction" is the direction connecting the side portions 21E, 21E.

The packaging bag 21 is preferably made of flexible thin sheet material. Resin, non-woven fabric, paper, and the like can be used as the material constituting the packaging bag 21, and although not limited, resin films (polyethylene film, polypropylene film, etc.) are particularly preferably used. When the resin film is used, it is preferable to use one with a transparent background color, and the content of the resin film is visible from the outside in most areas of the outer surface of the packaging bag 21 other than predetermined areas. An opaque colored print is applied, and the product name and other necessary information are printed.

As shown in FIGS. 1 and 2, at least the front portion 21C of the packaging bag 21 is formed with a window portion 23 through which the individually packaged sanitary napkin N inside can be visually recognized. The window portion 23 is formed so that the individually packaged sanitary napkin N stored inside the packaging bag 21 can be seen from the outside. When the packaging bag 21 is made of a transparent resin film, the window part 23 can be formed by partially not performing the printing as described above, and the packaging bag 21 is made of nonwoven fabric or paper. In some cases, it can be formed by an opening or a portion covered with a transparent resin film.

The shape of the window portion 23 is not particularly limited, and may be formed in a known shape as long as the individually packaged sanitary napkin N inside is easily visible. For example, in addition to the illustrated heart shape, circular, elliptical, polygonal, star, and diamond shapes can be used.

As shown in FIG. 2, the window portion 23 has a length L1 in the thickness direction of the individually packaged sanitary napkins N (in the illustrated example, the package body) so that the plurality of individually packaged sanitary napkins N can be visually recognized. 20) is 25% or more, preferably 25 to 50%, of the length P1 of the front portion 21C in this direction. Since 12 or more individually packaged sanitary napkins N are normally stored in one package 20, at least 3 individually packaged sanitary napkins N can be accommodated by forming them with a length of 25% or more. becomes visible through the window 23. In addition, the window portion 23 has a length L2 in a direction perpendicular to the thickness direction of the individually packaged sanitary napkin N (in the illustrated example, the length in the vertical direction of the package 20) is the length of the front portion 21C in this direction. It is preferably 20% or more, preferably 20 to 70%, and more preferably 25 to 50% of the length P2. The length L2 is a length that allows the individual sanitary napkin N inside to be visually recognized continuously in the direction orthogonal to the thickness direction. It is the maximum length in the direction perpendicular to the thickness of N.

One or more of the window portions 23 are provided in the front portion 21</b>C of the packaging bag 21 . When a plurality of windows 23 are provided, the windows 23 may be arranged separately and arranged independently, or may be arranged continuously such that the windows are partly connected to each other.

Also, a window portion through which the individually packaged sanitary napkin N inside can be visually recognized may be formed on the face portion of the packaging bag 21 other than the front face portion 21C.

On the upper surface portion 21A and the bottom surface portion 21B of the packaging bag 21, both side edges of a planar resin film are joined together to form a tubular shape with both ends opened, and then a sealing portion 22 for closing the openings at both ends. is formed. The sealing portion 22 is formed over the entire length in the left-right direction at the central portion in the front-rear direction of the top surface portion 21A and the bottom surface portion 21B. As the joining means for the sealing portion 22, known means such as heat sealing, ultrasonic sealing, and adhesives can be used.

[Individually packaged sanitary napkin N]
Next, the individually packaged sanitary napkin N stored in the packaging bag 21 will be described. As shown in FIGS. It is formed by folding the sanitary napkin 1 into a small size in the longitudinal direction.

In this specification, unless otherwise specified, the “longitudinal direction” is the direction connecting the front end and the rear end of the sanitary napkin 1, and the “width direction” is the sanitary napkin perpendicular to the longitudinal direction. It is the direction connecting both sides of 1.

As shown in FIGS. 5 and 6, the sanitary napkin 1 includes a liquid-impermeable back sheet 2 made of a polyethylene sheet or the like placed on the non-skin side, and a liquid-impermeable back sheet 2 placed on the skin side, and on the menstrual blood side. Absorption consisting of a liquid-permeable surface sheet 3 that allows liquids such as vaginal discharge (hereinafter collectively referred to as body fluids) to permeate quickly, and floc-like pulp or synthetic pulp interposed between the two sheets 2 and 3. A body 4 and side sheets 7, 7 provided on both sides of the skin-contacting surface side over substantially the entire length in the longitudinal direction. The outer edges of the back sheet 2 and the top sheet 3 are joined by a joining means such as hot melt adhesive, heat sealing, or ultrasonic sealing, and both side edges extend laterally beyond the absorber 4. The back sheet 2 and the side sheet 7 are joined by a joining means such as hot-melt adhesive, heat sealing, or ultrasonic sealing to form a flap portion in which the absorbent body 4 is not interposed. . A second sheet having substantially the same shape as the topsheet 3 may be arranged between the topsheet 3 and the absorbent body 4 and adjacent to the non-skin side of the topsheet 3 .

The structure of the sanitary napkin 1 will be further detailed below.
For the back sheet 2, a sheet material having at least water impermeability, such as polyethylene, is used, but it is desirable to use a material having moisture permeability from the viewpoint of preventing stuffiness. The water-impervious/moisture-permeable sheet material is produced by melting and kneading an inorganic filler in an olefin resin such as polyethylene or polypropylene to form a sheet, and then stretching the sheet in a uniaxial or biaxial direction. A sheet is preferably used. As the back sheet 2, a polylaminated nonwoven fabric obtained by laminating a plastic film and a nonwoven fabric may be used.

Next, for the surface sheet 3, a perforated or non-perforated nonwoven fabric, a porous plastic sheet, or the like is preferably used. The material fibers that make up the nonwoven fabric include synthetic fibers such as olefins such as polyethylene or polypropylene, polyesters, and polyamides, as well as recycled fibers such as rayon and cupra, and natural fibers such as cotton. A nonwoven fabric obtained by an appropriate processing method such as a method, a spunbond method, a thermal bond method, a meltblown method, a needle punch method, or the like can be used. Among these processing methods, the spunlace method is superior in flexibility and drapeability, and the thermal bond method is superior in bulkiness and compression recovery. When a large number of through holes are formed in the surface sheet 3, body fluids are rapidly absorbed, and the dry touch property is excellent. The fibers of the non-woven fabric may be either long fibers or short fibers, but preferably short fibers are used in order to produce the feel of a terry cloth. Also, in order to facilitate embossing, it is preferable to use olefin fibers such as polyethylene or polypropylene having a relatively low melting point. In addition, composite fibers of core-sheath type fibers, side-by-side type fibers, and split type fibers having a high melting point fiber as a core and a low melting point fiber as a sheath can also be preferably used.

The absorbent body 4 interposed between the backsheet 2 and the topsheet 3 is made of, for example, cotton-like pulp and a water-absorbent polymer. The water-absorbing polymer is mixed in the pulp constituting the absorbent body, for example, as granular powder. Examples of the pulp include chemical pulp obtained from wood, cellulose fibers such as dissolving pulp, and artificial cellulose fibers such as rayon and acetate. Softwood pulp with a longer fiber length is more functional and functional than hardwood pulp. It is preferably used in terms of price. As for the manufacturing method of the absorbent body 4, it is desirable to use piled pulp so as to have high flexibility, but it is also possible to use an air-laid absorbent body that can reduce the volume. The absorbent body 4 may be surrounded by an enveloping sheet (not shown) made of crepe paper, non-woven fabric, or the like in order to retain its shape and improve diffusion.

Synthetic fibers may also be mixed in the absorber 4 . For the synthetic fibers, for example, polyolefins such as polyethylene or polypropylene, polyesters such as polyethylene terephthalate and polybutylene terephthalate, polyamides such as nylon, and copolymers thereof can be used. A mixture may also be used. In addition, composite fibers such as core-sheath type fibers, side-by-side type fibers, and split type fibers having a high-melting-point fiber as a core and a low-melting-point fiber as a sheath can also be used. In the case of hydrophobic fibers, the synthetic fibers are preferably surface-treated with a hydrophilizing agent so as to have affinity for body fluids.

In the illustrated example, the width dimension of the topsheet 3 is substantially the same as the width of the absorbent body 4, and it only covers the absorbent body 4, and the outer side thereof is a side sheet 7 different from the topsheet 3. Specifically, it is constructed using a non-woven fabric material that has undergone appropriate water-repellent or hydrophilic treatment according to the purpose of preventing the penetration of menstrual blood, vaginal discharge, etc., or improving the feel of the skin. A side seat 7 is provided.

The side sheet 7 may be made of natural fiber, synthetic fiber, regenerated fiber, or the like, and may be formed by an appropriate processing method. It is better to use an elevated nonwoven fabric. Specifically, it is desirable to use a non-woven fabric with a basis weight of 13 to 23 g/m ² , and in order to reliably prevent permeation of body fluids, silicone-based, paraffin-based, alkylchromic chloride-based water repellents, etc. A water-repellent nonwoven fabric coated with is preferably used.

The side sheet 7 is adhered with an adhesive such as a hot-melt adhesive over a range from a predetermined inner position to the outer edge of the back sheet 2 from the middle portion in the width direction. A side flap portion is formed on both sides of the absorbent body 4 by the laminated sheet portion of the absorbent body 4, in which the absorbent body 4 is not interposed. The flap portion has a pair of left and right wing-shaped flaps W, W on both sides of a portion substantially corresponding to the bodily fluid discharge portion H. As shown in FIG. A longitudinal section including the wing-shaped flaps W corresponds to the crotch portion of the wearer. Further, a pair of left and right hip hold flap portions extending in the width direction may be formed behind the wing-shaped flaps W, W. As shown in FIG.

On the other hand, in the illustrated example, the inner side portion of the side sheet 7 is laminated on the skin side of the topsheet 3 and adhered to the absorber 4 side (the skin side of the topsheet 3), but the width direction A three-dimensional gather that stands up toward the wearer's skin may be formed by folding the garment into two and arranging an elastic stretchable member in the folded portion along the longitudinal direction.

On the non-skin side (the outer surface of the back sheet 2) of the body portion where the absorbent body 4 is interposed between the top sheet 3 and the back sheet 2, an appropriate application pattern is applied for fixing to underwear when worn on the body. By one or a plurality of lines, in the illustrated example, three lines of main body anti-slip adhesive layers 8, 8 ... are formed along the longitudinal direction of the napkin, and these main body anti-slip adhesive layers 8, 8 ... are for the main body It is releasably covered with a release material 5 (see FIG. 9). In addition, on the non-skin side surfaces of the wing-shaped flaps W, W (outer surface of the back sheet 2), when worn on underwear, the wing-shaped flaps W, W are positioned at the base end folding line RL (see FIG. 1). The wing slip-preventing adhesive layers 9, 9 for winding and fixing to the crotch part of the underwear are formed, and these wing slip-preventing adhesive layers 9, 9 cross in the width direction. It is peelably covered with one sheet of wing peeling material 6 (see FIGS. 8 and 9). Further, in the case where the aforementioned hip hold flap portion is formed behind the wing-shaped flap W, the non-skin side surface (outer surface of the back sheet 2) of the hip hold flap portion is provided with an anti-slip adhesive layer. In this way, the anti-slipping adhesive layer formed on the hip hold flap portion may be releasably covered by the rearwardly extending portion of the wing release material 6 .

In order to individually pack the above sanitary napkin 1, as shown in FIG. 7, the flaps on both sides are folded toward the top sheet 3 with the side edge of the absorbent body 4 as the base end, and then folded. 8 and FIG. 9, it is placed on an individual packaging sheet 10 to which the main body release material 5 is fixed to the abutting portions of the main body anti-slip adhesive layers 8, 8 . . . The agent layers 9, 9 are covered with the wing release material 6, and the sanitary napkin 1 is folded along with the individual packaging sheet 10 in the longitudinal direction.

A rectangular sheet having a predetermined size is used as the individual packaging sheet 10 . Non-woven fabric, plastic film, paper, etc. can be used as the material. The width of the individual packaging sheet 10 is narrower than the unfolded width of the sanitary napkin 1 (the distance between the tips of the wing-shaped flaps W, W), and the flaps on both sides are folded (the state shown in FIG. 7). is also formed in a rectangular shape with a predetermined length.

As shown in FIG. 8, the individual packaging sheet 10 is folded so that at least one short side 10b of the individual packaging sheet 10 is positioned outside one of the front and rear ends (front end) of the sanitary napkin 1. As shown in FIG. The sanitary napkin 1 is arranged on the inner surface of the sanitary napkin 1, and the individual packaging sheet 10, the main body release material 5, and the wing release material 6 are firmly adhered to each other by a hot-melt adhesive or the like in predetermined fixation regions.

When the sanitary napkin 1 is placed at a predetermined position on the individual packaging sheet 10, the sanitary napkin 1 and the individual packaging sheet 10 are folded in the longitudinal direction along the folding lines X1, X2, and X3 along the width direction. Fold to one side. The fold lines have a rear fold line X1, an intermediate fold line X2, and a front fold line X3 in order from the rear side of the sanitary napkin 1. As shown in FIG.

As for the folding procedure, first, the rear end of the napkin along with the individually packaged sheet 10 is folded toward the sanitary napkin 1 in the longitudinal direction along the rear folding line X1, and then the folded portion is folded along the intermediate folding line. At the X2 position, the individual packaging sheet 10 is folded in the longitudinal direction to the area where the wing-shaped flaps W are arranged. After that, the front end of the napkin is folded at the position of the front folding line X3 so as to overlap the upper surface of the rear end that has been folded in two, and as shown in FIG. Sealing is performed by a suitable sealing means such as embossed pressure bonding, heat sealing, adhesive agent, or the like, alone or in combination. Moreover, the longitudinal edge 10b of the individual packaging sheet 10 is preferably sealed with a tab tape 11 after bonding with an adhesive. Thus, the sanitary napkin 1 is individually packaged.

As shown in FIG. 3, the individually packaged sanitary napkin N folded in the longitudinal direction in this manner is formed into a flat rectangular shape, with two opposing sides on one side being folded portions 10c and 10c, respectively, and the other side folded. The two sides facing each other are the sealing portions (both side edge portions 10a, 10a).

The direction in which the individually packaged sanitary napkin N is accommodated in the packaging bag 21 is such that the folded portion 10c of the individually packaged sanitary napkin N faces the front portion 21C of the packaging bag 21 having the window portion 23. do. In FIG. 1, a pair of side portions forming the folded portion 10c are opposed to the front portion 21C and the rear portion 21D, respectively, and a pair of side portions forming the sealing portion (side edge portions 10a, 10a) are respectively The plane of the individually packaged sanitary napkin N faces the top surface portion 21A and the bottom surface portion 21B, and is arranged in a vertical direction perpendicular to the horizontal direction between the side surfaces 21E, 21E. Also, although not shown, a pair of side portions forming the folded portion 10c are opposed to the front portion 21C and the rear portion 21D, respectively, and a pair of side portions forming the sealing portion (side edge portions 10a, 10a). may face the side portions 21E, 21E, respectively, and the plane of the individually packaged sanitary napkin N may be arranged horizontally perpendicular to the vertical direction between the top portion 21A and the bottom portion 21B.

[Color area of individual packaging sheet 10]
In the package 20 of the sanitary napkin 1 according to the present invention, the individual packaging sheet 10 in the portion facing the window portion 23 has a plurality of color regions of different colors partitioned in the thickness direction of the individually packaged sanitary napkin N. , in the illustrated example, a first color region 12 and a second color region 13 are provided. That is, along the folding line when the sanitary napkin 1 is folded together with the individually packaged sheet 10, the folding part 10c of the individually packaged sheet 10 facing from the window part 23 of the individually packaged sanitary napkin N is folded. A single color area 12 and a second color area 13 are provided. The first color region 12 and the second color region 13 are provided along the folding line and adjacent to each other in the thickness direction of the individually packaged sanitary napkin N (longitudinal direction of the sanitary napkin 1). A plurality of color regions can be visually recognized through the window portion 23 within the thickness range of the sanitary napkin N. As shown in FIG. As shown in FIG. 1, each of the plurality of individually packaged sanitary napkins N seen through the window 23 is provided with the first color region 12 and the second color region 13, thereby forming a striped pattern as a whole. Vertical stripes are formed when the individually packaged sanitary napkins N are arranged vertically as in the illustrated example, and horizontal stripes are formed when the individually packaged sanitary napkins N are arranged horizontally (not shown).

By forming the plurality of color regions 12 and 13 on the portion of the individually packaged sheet 10 facing the window portion 23, the portions partitioned by the plurality of color regions can be formed with the thickness of one individually packaged sanitary napkin N. Therefore, the thickness of the individually packaged sanitary napkin N can be clearly recognized at a glance of the window portion 23 . In other words, among the regular striped pattern formed by a plurality of color regions visible through the window 23, a combination of color regions that constitute one unit of stripes can be recognized as one individually packaged sanitary napkin N. The thickness of the sanitary napkin N can be clearly recognized at a glance. Therefore, even when the sanitary napkin N is stored in the packaging bag 21, it can be clearly determined whether the individually packaged sanitary napkin N is thick or thin, and it is easy to imagine how the sanitary napkin N is carried in a bag. There are various thicknesses of the sanitary napkin 1, such as one that is as thin as possible in order to reduce discomfort when worn, and one that is thick enough to give the user a sense of security. The degree can be clearly recognized without taking it out of the packaging bag 21.例文帳に追加

As an embodiment of the first color region 12 and the second color region 13, as shown in FIGS. When the area is divided into two areas, the first color area 12 can be provided in one area and the second color area 13 can be provided in the other area. Accordingly, as shown in FIGS. 1 and 2, the first color regions 12 and the second color regions 13 are alternately arranged between the adjacent individually packaged sanitary napkins N, N. The thickness of the combination of the region 12 and the second color region 13 can be more clearly recognized as one individually packaged sanitary napkin N. That is, since the first color regions 12 and the second color regions 13 having different colors are alternately arranged adjacent to each other, the first color regions 12 and the second color regions 13 are recognized as one individually packaged sanitary napkin N. In addition, since different color regions are arranged in adjacent portions of adjacent individually packaged sanitary napkins N, the boundary between adjacent individually packaged sanitary napkins N can be clearly distinguished.

Here, the first color region 12 and the second color region 13 are preferably provided at a ratio of approximately 1/2 of the thickness of the portion facing the window 23 of each individually packaged sanitary napkin N. As a result, the first color regions 12 and the second color regions 13 are alternately arranged with substantially equal widths through the window portion 23, so that the set of the first color regions 12 and the second color regions 13 can be combined into one unit. It becomes easy to recognize the thickness of the sanitary napkin N. In order to form the first color area 12 and the second color area 13 to have substantially the same width, as shown in FIG. 10, the first color areas having substantially the same width are formed before and after the front fold line X3 as a boundary. 12 and a second color region 13.

As shown in FIG. 10, the first color area 12 and the second color area 13 are provided along the folding line X3 along which the individual packaging sheet 10 is folded, and are also provided in the adjacent front and back portions in the same manner. preferable. As a result, even if the folding positions are misaligned, the first color area 12 and the second color area 13 are arranged at desired positions.

In addition, the portion facing the window portion 23 of each individually packaged sanitary napkin N is divided into two regions in the thickness direction, and the respective regions are the first color region 12 and the second color region 13. When arranging the two-color areas 13 before and after the folding line X3 as a boundary, the first-color area 12 and the second-color area 13 are arranged with respect to the thickness of the portion facing the window 23 of each individually packaged sanitary napkin N. , and may be formed with a width greater than 1/2. As a result, even if the boundary between the first color region 12 and the second color region 13 is not exactly folded in half and the folding line is slightly shifted forward and backward, the color regions extend to the front and rear portions, so that one side of the color region is folded. Another color is no longer visible from the side edges of the color area.

The colors of the adjacent color regions are preferably 24 color charts classified by the Ostwald color wheel, and the hue numbers are shifted by 6 or more. This makes it easier to distinguish between two adjacent color regions. Also, the colors of the adjacent color regions may be a white-based color and a black-based color. Here, the white base color means that ΔL ^* in the (L ^* a ^* b ^* ) color space for the standard white plate (L ^* =96.76, a ^* =+0.44, b ^* =2.17) is A color of 4.0 or less, and a black-based color is a color of 54.0 or more in ΔL ^* in the (L ^* a ^* b ^* ) color space with respect to the standard white plate. Also, the colors of the adjacent color regions may be composed of a color having a specific hue such as red, blue, and yellow, and a white-based color or a black-based color.

In order to make it easier to clearly distinguish adjacent color regions, it is more preferable that the colors of the adjacent color regions are complementary colors. Complementary colors refer to colors that are opposite to each other on the color wheel, and vary depending on the color expression method. For example, in the case of RYB, red and green, blue and orange, yellow and purple, and RGB In the case of , there are relationships between red and cyan, magenta and green, and yellow and blue. Furthermore, in order to clearly recognize that the first color region 12 and the second color region 13 form one individually packaged sanitary napkin N, the first color region 12 and the second color region 13 may be mixed to form a gradually changing gradation.

In order to apply the first color region 12 and the second color region 13, either one of the first color region 12 or the second color region 13 is the background color of the individual packaging sheet 10, and the outer surface of the individual packaging sheet 10 is colored. Either one of the other color areas can be provided in a predetermined area of the other by printing or bonding of another member.

As shown in FIG. 10, the color region is preferably provided along the front folding line X3 among the folding lines X1 to X3 along which the sanitary napkin 1 and the individual packaging sheet 10 are folded in the longitudinal direction. This front folding line X3 is the final folding line for laminating the front portion of the sanitary napkin 1 on top of the rear portion of the sanitary napkin 1 folded in two, as described in the folding procedure described above. Positional deviation is less likely to occur, and polygonal lines are likely to be formed at relatively stable positions. Therefore, by providing the color areas along the front folding line X3, the first color area 12 and the second color area 13 are easily formed at desired positions.

As shown in the illustrated example, it is preferable that the color area is provided only along the front fold line X3 and not provided along the other fold lines X1 and X2. That is, the color region is provided only on one folded portion 10c of the pair of folded portions 10c, 10c. The window portion 23 is often provided only in the front portion 21C of the packaging bag 21 and not provided in the rear portion 21D on the opposite side. facing each other and storing the individually packaged sanitary napkin N in the packaging bag 21 , the first color region 12 and the second color region 13 can be seen through the window 23 . Moreover, since the range in which the color regions are provided can be limited, manufacturing can be simplified. Furthermore, when the sanitary napkin 1 is attached, when the individually packaged sanitary napkin N is taken out from the packaging bag 21 and opened, the folding part 10c provided with the color region is placed upward and opened, so that the sanitary napkin 1 is always individually packaged. Since the sanitary napkin 1 can be taken out with the front side facing upward, the sanitary napkin 1 can be taken out from the individual package and worn on the underwear without worrying about the top and bottom of the sanitary napkin 1 when worn. can be simplified.

On the other hand, although not shown, the color regions are formed along both the intermediate folding line X2 and the front folding line X3 among the folding lines X1 to X3 along which the sanitary napkin 1 is longitudinally folded together with the individual packaging sheet 10. may be provided. That is, the color regions are provided on both of the pair of folded portions 10c, 10c. In this case, the individually packaged sanitary napkin N can be stored in the packaging bag 21 without worrying about its orientation, and the window part 23 is provided not only in the front part 21C of the packaging bag 21 but also in the back part 21D. Even in this case, the color area of the individually packaged sanitary napkin N inside can be seen through the window 23 provided in the back portion 21D.

The color area may be provided in at least a part of the individual packaging sheet 10 in the width direction facing the window 23, but as shown in FIG. is preferred. As a result, even if the individually packaged sanitary napkins N stored in the packaging bag 21 are slightly displaced within the packaging bag 21, the color area can be reliably seen through the window portion 23.例文帳に追加

Another embodiment of the color area will be described with reference to FIGS. 11 and 12. FIG. In the embodiment shown in FIGS. 11 and 12, the color area is composed of the first color area 12 and the second color area 13 as in the above embodiment. In this embodiment, when the portion facing the window portion 23 of each individually packaged sanitary napkin N is partitioned into three regions in the thickness direction, the first color region 12 is located in the central region of the three partitioned regions. and the second color regions 13 are provided on both sides thereof. In other words, the folded portion 10c visible through the window portion 23 of each individually packaged sanitary napkin N has a first color region 12 along the folding line in the central portion in the thickness direction, and a second region 13 on both sides thereof. As a result, the first color area 12 is sandwiched between the second color areas 13 , 13 . Therefore, it is easy to recognize that the thickness of one individually packaged sanitary napkin N is the portion sandwiched between the second color regions 13, 13 on both sides. Therefore, since the thickness of each individually packaged sanitary napkin N can be recognized by using the second color regions 13, 13 on both sides as marks, the folding line position when folding the sanitary napkin 1 along with the individually packaged sheet 10 in the longitudinal direction is slightly different. Even if there is a shift, the thickness of the individually packaged sanitary napkin N can be recognized as long as the second color regions 13, 13 on both sides are visible.

At this time, the width of the first color region 12 is formed at a ratio of approximately 1/2 of the thickness of the portion facing the window portion 23 of each individually packaged sanitary napkin N, and the width of the second color region 13 is is preferably formed at a ratio of about 1/4 of the thickness of the portion of each individually packaged sanitary napkin N facing through the window portion 23 . In this way, by setting the width of the second color region 13, which marks the boundary between adjacent individually packaged sanitary napkins N, to approximately half the width of the central first color region 12, the individually packaged sanitary napkin N The role as a contour line that divides N becomes clear, and the thickness of one individually packaged sanitary napkin N becomes easier to recognize.
