<Basic configuration of sanitary napkin 1 in the unfolded state>
FIG. 1 is a plan view of a deployed napkin 1 (hereinafter referred to as a napkin) as viewed from the skin side in the thickness direction. It is the top view which looked at the sanitary napkin 1 (henceforth napkin) from the skin side of the thickness direction. FIG. 2 is a plan view of the napkin 1 viewed from the non-skin side in the thickness direction. In FIG. 2, the packaging material 50 is omitted for convenience. FIG. 3 is a schematic cross-sectional view of the central part in the longitudinal direction of the napkin 1 in the unfolded state. The napkin 1 has a longitudinal direction, a width direction, and a thickness direction that are orthogonal to each other. Further, in the longitudinal direction of the napkin 1, the side that comes into contact with the lower abdomen of the wearer is called “front side”, and the side that comes into contact with the buttocks of the wearer is called “rear side”. Further, in the thickness direction of the napkin 1, the side that contacts the wearer is referred to as “skin side”, and the opposite side is referred to as “non-skin side”. A package 100 (FIG. 6A) is constituted by the folded napkin 1 and the packaging material 50 for packaging the napkin 1.

  As shown in FIG. 3, in the napkin 1, in order from the skin side in the thickness direction, a pair of side sheets 2, a top sheet (skin side sheet) 3, a second sheet (sheet member) 4, and an absorber 10, The back sheet (non-skin side sheet) 5 is laminated, and the packaging material 50 is provided on the non-skin side of the napkin 1. Each member 2, 3, 4, 10, 5 is joined to a member adjacent in the thickness direction with an adhesive (not shown). The napkin 1 includes a napkin main body portion 20 provided with the absorbent body 10 and a pair of wing portions 30 extending from the longitudinal central region of the napkin main body portion 20 to both outer sides in the width direction. However, the napkin 1 may not have the wing part 30.

  The top sheet 3 is a liquid-permeable sheet whose skin side surface and non-skin side surface are white, and examples thereof include an air-through nonwoven fabric. The back sheet 5 is a liquid-impermeable sheet whose skin side surface and non-skin side surface are pink, and can be exemplified by a polyethylene (PE) resin film and the like. The top sheet 3 and the back sheet 5 have a larger planar size than the absorbent body 10 and cover the entire planar surface of the absorbent body 10.

  The side sheets 2 are a pair of white liquid-permeable sheets provided at both ends in the width direction of the napkin 1 and are sheet members that do not have through holes. Examples of the material of the side sheet 2 include the same air-through nonwoven fabric as that of the top sheet 3. The side sheet 2 may be a liquid permeable sheet or a liquid impermeable sheet.

  The pair of side sheets 2 extends from both sides in the width direction of the top sheet 3 to the outside in the width direction, and forms a pair of wing portions 30 together with the back sheet 5. Further, the side sheet 2 does not have a portion overlapping the absorber 10 in the thickness direction. That is, in the width direction, the absorbent body 10 is provided at the center, and each side sheet 2 is provided outside the absorbent body 10. An end 2e on the inner side of the side sheet 2 on one side (for example, the left side in FIG. 1) in the width direction is located on the outer side (left side) of the end 10e on one side of the absorbent body 10, and the other side (for example, for example, The inner end 2e of the side seat 2 (on the right side in FIG. 1) is located on the outer side (right side) of the other end 10e of the absorbent body 10.

  Here, “the end 10 e of the absorber 10” refers to a portion of the absorber 10 that is located on the outermost side in the width direction. In this embodiment, it has the end 10et located in the front side of a longitudinal direction, the end 10em located in the approximate center of a longitudinal direction, and the end 10eb located in the back side of a longitudinal direction.

  The second sheet 4 is a white liquid-permeable sheet and can be exemplified by the same air-through nonwoven fabric as the top sheet 3. The second sheet 4 is provided on the skin side surface of the absorbent body 10, prevents the return of excrement such as menstrual blood, improves the diffusion of excrement, improves the cushioning property, and excretes the menstrual blood absorbed by the absorbent body 10. It plays the role of adjusting the color of objects. The second sheet 4 is provided in the center of the napkin 1 in the width direction, the length in the longitudinal direction is from the front end to the rear end of the napkin 1, and the length in the width direction is the absorber 10. Each end 4e in the width direction of the second sheet 4 is shorter and is located inside each end 10e of the absorbent body 10.

  On the non-skin side surface (that is, the non-skin side surface of the back sheet 5) in the thickness direction of the napkin main body portion 20, a main body pressure-sensitive adhesive portion 21 is provided. When the napkin 1 is used, the main body adhesive section 21 is affixed to the side of the skin such as underwear, whereby the napkin 1 is fixed to the underwear or the like. In the main body adhesive section 21 shown in FIG. 2, three rectangular adhesive sections having long sides in the longitudinal direction are arranged at intervals in the longitudinal direction, and the row of the three adhesive sections is arranged in the width direction. Eight rows are arranged at intervals.

  Similarly, a wing portion adhesive portion 31 is provided on the non-skin side surface (that is, the non-skin side surface of the back sheet 5) in the thickness direction of each wing portion 30. When the napkin 1 is used, the wing portion 30 is bent toward the non-skin side, and the wing portion adhesive portion 31 is attached to the non-skin side surface such as underwear, whereby the napkin 1 is fixed to the underwear or the like. The wing adhesive portion 31 shown in FIG. 2 is a rectangular adhesive portion having a long side in the longitudinal direction.

  Absorber 10 is a member that absorbs excrement and holds it inside. Absorbent core 12, upper layer sheet 11 on the skin side in the thickness direction of absorbent core 12, and thicker than absorbent core 12. The lower layer sheet 13 is provided on the non-skin side in the vertical direction, and the members 11 to 13 are laminated in the thickness direction. The absorptive core 12 should just have a liquid absorptive fiber, and can contain what contains a superabsorbent polymer (what is called SAP) in liquid absorptive fibers, such as a pulp fiber. The upper layer sheet 11 is a liquid-permeable sheet and can be exemplified by tissue paper and the like. The lower layer sheet 13 may be a liquid-permeable sheet or a liquid-impermeable sheet, and examples thereof include an SMS (spunbond / meltblown / spunbond) nonwoven fabric. The absorbent core 12, the upper layer sheet 11, and the lower layer sheet 13 may have the same planar shape or may have different planar shapes. In addition, it is assumed that the members 11 to 13 may or may not be joined to each other by an adhesive. In addition, the upper layer sheet | seat 11, the absorptive core 12, and the lower layer sheet | seat 13 are each white, and the absorber 10 is white as a whole.

  The absorber 10, the second sheet 4 and the top sheet 3 are all white, but in the present embodiment, the absorber 10 has the highest whiteness among the absorber 10, the second sheet 4 and the top sheet 3, and subsequently The whiteness decreases in the order of the second sheet 4 and the top sheet 3. “Whiteness” indicates the degree of whiteness of the surface color, and the surface color recognized as white by the standard light source D65 is displayed by the whiteness index. Can be obtained by measuring with 1200 lx of illumination. Using the second sheet 4 having a higher whiteness than the top sheet 3 and relaxing the color of excrement such as menstrual blood absorbed by the absorber 10, the second sheet 4 has a lower whiteness than the absorber 10. Thus, the absorber 10 can be visually recognized through the second sheet 4. Of the absorber 10, the second sheet 4, and the top sheet 3, the light transmittance of the absorber 10 is the lowest, and the light transmittance is increased in the order of the second sheet 4 and the top sheet 3. “Light transmittance” is a ratio of the amount of light transmitted through a substance expressed as a ratio of the amount of light after transmission and the amount of light before transmission, and was measured using a spectrophotometer or a photoelectric photometer. It is a ratio. In the present embodiment, the second sheet 4 having a light transmittance higher than that of the absorber 10 is also used for a portion in which a part of the absorber 10 (the central portion in the width direction of the absorber 10) is covered by the second sheet 4. Therefore, when it sees from the skin side, the possibility that the absorber 10 may be covered with the second sheet 4 can be reduced.

  Further, the absorbent body 10 is provided with a folding guide portion 14 that guides the absorbent body 10 to protrude and bend toward the skin side in the thickness direction. Therefore, when the force of pinching the wearer's legs is applied when the napkin 1 is worn, the central region in the longitudinal direction of the absorbent body 10 has a shape that protrudes toward the skin side from the side in the width direction toward the center. Deformed, making it easy to adhere to the excretion opening (vaginal opening) of the wearer. Further, the absorbent body 10 is provided with a rear missing portion 15, a front missing portion 16, a pair of rear cutout portions 17, and a pair of front cutout portions 18.

  In addition, the napkin 1 is a portion that is recessed from the skin side in the thickness direction toward the non-skin side, and is provided with a plurality of compressed portions 40 (concave portions) having a higher density of liquid absorbent fibers than adjacent portions. ing. In the pressing part 40, the top sheet 3, the second sheet 4, and the whole area of the absorber 10 in the thickness direction are pressed (embossed) from the skin side in the thickness direction and joined and integrated. Moreover, suppose that the fabric weight of a liquid absorptive fiber is equal in the pressing part 40 and the site | part adjacent to it, and the density becomes high by pressing the liquid absorptive fiber in the pressing part 40. FIG. In addition, it is not restricted to the above, The pressing part 40 is provided only in the absorber 10, or the pressing part 40 is provided only from the top sheet 3 to a part on the skin side in the thickness direction of the absorbent core 12, or the back sheet 5 Alternatively, the compressed portion 40 may be provided in the absorbent body 10.

  The packaging material 50 is a white sheet member for individually packaging the napkin 1, and is formed of various films such as a plastic film and a nylon film, a nonwoven fabric, a film obtained by laminating a nonwoven fabric, and the like. The packaging material 50 is joined in a state of being overlapped in the thickness direction of the napkin 1 before the napkin 1 is used, and is removed from the napkin 1 when the napkin 1 is used. In addition, the napkin 1 and the packaging material 50 are joined by the main body portion adhesive portion 21 and the wing portion adhesive portion 31 provided on the back sheet 5.

  In addition, a tape 51 for holding the napkin 1 in a folded state is provided at the front end of the packaging material 50. The tape 51 is pulled by the user when the folded napkin 1 is unfolded (opened).

<About individual package 100>
As shown in FIG. 1, the napkin 1 of the present embodiment includes a first longitudinal fold Q1 on one side in the width direction (left side in FIG. 1) and the other side in the width direction as longitudinal folds along the longitudinal direction. As the second longitudinal fold Q2 (on the right side in FIG. 1) and the width fold along the width direction, there are a first width fold P1 on the front side in the longitudinal direction and a second width fold P2 on the rear side in the longitudinal direction. ing. Starting from each of the folds P1, P2, Q1, and Q2, the napkin 1 and the packaging material 50 are folded in the longitudinal direction and the width direction, whereby the individual package 100 (FIG. 6A) is formed.

  In the present embodiment, first, with the first longitudinal fold Q1 as a base point, the napkin 1 in a state of being stacked in the thickness direction and one end side in the width direction of the packaging material 50 (left side in FIG. 1) are folded inward. Subsequently, the other end side (the right side in FIG. 1) of the napkin 1 and the packaging material 50 in the width direction is folded inward with the second longitudinal fold Q2 as a base point. Furthermore, with the second width fold line P2 as a base point, one end side in the longitudinal direction of the napkin 1 and the packaging material 50 is folded inward. Finally, the other end side in the longitudinal direction of the napkin 1 and the packaging material 50 (the front side in FIG. 1) is folded inward with the first fold line P1 as a base point, and the folded state by the tape 51 is maintained.

<About the state when the napkin 1 is seen from the skin side>
Hereinafter, the state when the napkin 1 is viewed from the skin side will be described. As shown in FIGS. 1 and 3, the inner end 2 e of the side sheet 2 on one side (the left side in FIGS. 1 and 3) in the width direction of the napkin 1 is outside the end 10 e on one side of the absorbent body 10 ( The inner end 2e of the side sheet 2 on the other side in the width direction (the right side in FIGS. 1 and 3) is on the outer side (more on the right side) than the other end 10e of the absorbent body 10. positioned. That is, as shown in FIG. 3, each end 10 e in the width direction of the absorbent body 10 is not covered by any side sheet 2, so that the top sheet 3 is disposed on the skin side in the thickness direction of the absorbent body 10. Only arranged.

  Therefore, when a wearer uses the napkin 1 or the like, when the napkin 1 is viewed from the skin side, it absorbs more than when the top sheet 3 and the side sheet 2 are provided on the skin side from the absorbent body 10. It becomes easier to visually recognize the end 10e of the body 10. Even when both the top sheet 3 and the side sheet 2 are white, the more members are stacked in the thickness direction, the more difficult it is to see the end 10e of the absorber 10 when the absorber 10 is viewed through the stacked members. Because it becomes.

  In the napkin 1 of the present embodiment, the inner end 2e of the side sheet 2 on one side and the end 10e of the absorbent body 10 are separated from each other by a predetermined distance in the width direction. 2 is separated from the inner end 2e of the absorber 2 by an end 10e of the absorber.

  Similarly, since the length in the width direction of the second sheet 4 arranged at the center in the width direction of the napkin 1 is shorter than the length in the width direction of the absorbent body 10, each end 4 e of the second sheet 4 is It is located inside the width direction from the end 10e. Therefore, it becomes easier to visually recognize the end 10e of the absorbent body 10 than when the end 10e of the absorbent body 10 is covered with the second sheet 4.

  Further, when the napkin 1 is viewed from the skin side, the white color of the absorbent body 10 and the pink color of the back sheet 5 can be visually recognized. Thereby, since the pink area | region of the back sheet 5 can be visually recognized in the area | region between the edge 10e of the white absorber 10 and the edge 2e inside the white side sheet | seat 2, the absorber 10 is depending on a color boundary. Can be easily recognized.

  In the present embodiment, the white absorbent body 10 and the pink back sheet 5 are provided. However, the present invention is not limited to this. You may use the absorber 10 and the white backsheet 5 which were colored in arbitrary colors, for example, green. At this time, when the napkin 1 is viewed from the skin side, the region between the end 10e of the absorbent body 10 and the inner end 2e of the side sheet 2 is white, and due to the color boundary with the green color at the end of the absorbent body 10 The end 10e of the absorber 10 can be easily recognized. The absorber 10 may be colored by coloring the upper layer sheet 11 or by coloring liquid absorbent fibers such as pulp fibers contained in the absorbent core 12.

  Thus, when the napkin 1 is seen from the skin side, the area between the end 10e of the absorbent body 10 and the inner end 2e of the side sheet 2 because the colors of the absorbent body 10 and the back sheet 5 are different. Since it becomes easy to recognize the boundary between the color of the back sheet 5 that can be seen and the color of the end portion of the absorbent body 10 and the end 10e of the absorbent body can be more easily recognized, the wearer configures the configuration of the napkin 1 to be worn. I can know.

  Note that both the absorbent body 10 and the back sheet 5 may be colored. For example, even when the absorber 10 is green and the back sheet 5 is pink, the end 10e of the absorber 10 can be easily recognized. At this time, it is preferable that the color of the absorber 10 and the color of the back sheet 5 are different.

  Subsequently, the difference in color when the napkin 1 in the unfolded state is viewed from the skin side will be described in detail. FIG. 4 is a diagram illustrating a state in which the napkin 1 in a developed state is viewed from the skin side. The color of the region of the napkin 1 in the developed state differs depending on the type and number of members stacked in the thickness direction. In FIG. 4, the region having a different color when viewed from the skin side is different. Shown by hatching. In addition, in FIG. 4, the pressing part 40 is abbreviate | omitted for convenience.

  4 is a region where the top sheet 3, the second sheet 4, the absorber 10, and the back sheet 5 are overlapped. A region B (a portion with a horizontal line in FIG. 4) is a region where the top sheet 3, the absorbent body 10, and the back sheet 5 are overlapped. A region C (a portion with a double slanted line in the lower left in FIG. 4) is a region where the top sheet 3, the second sheet 4 and the back sheet 5 are overlapped. A region D (portion with the cross pattern in FIG. 4) is a region where the top sheet 3 and the back sheet 5 are overlapped. A region E (a portion with a slanting line in the lower left of FIG. 4) is a region where the side sheet 2, the top sheet 3, and the back sheet 5 are overlapped. The region F (the portion with the right-down triple diagonal line in FIG. 4) is a region where the side seat 2 and the back seat 5 are overlapped. The region G is a region where the packaging material 50 is provided.

  In this embodiment, the side sheet 2, the top sheet 3, the second sheet 4, the absorber 10, and the packaging material 50 are each white, and the back sheet 5 is pink. At this time, the color of the back sheet 5 can be visually recognized as the number of members stacked on the back sheet 5 is small or the light transmittance of the members stacked on the back sheet 5 is high. Of the regions A to F, the region D in which the member stacked on the back sheet 5 is only the top sheet 3 can visually recognize the color of the back sheet 5 more than the other regions A, B, C, E, and F. it can. That is, the color of region D looks darkest. Even when the region G is taken into consideration, the packaging material 50 is white, so the region D is the darkest part.

  FIG. 5 is a diagram illustrating each region adjacent from the outer side in the width direction of the end region (region b) of the absorbent body 10. Assuming the regions A to G shown in FIG. 4, FIG. 5 shows a region b, a region d, a region e, a region f, and a region g. Of the region B, the end region of the absorber 10 with reference to the end 10e (10et, 10em, 10eb) of the absorber 10 is a region b. Of the region D, the region adjacent to the region b from the outside in the width direction is the region d (first region). Of the region E, a region adjacent to the region d from the outside in the width direction is a region e (second region). Of the region F, the region adjacent to the region e from the outside in the width direction is a region f (third region). Of the region G, the region adjacent to the region f from the outside in the width direction is a region g (packaging region). In the present embodiment, the region b, the region d, the region e, the region f, and the region g are the ranges shown in FIG. 5, but the region is not limited to this as long as the region is based on the end 10e. If each region changes, each region in FIG. 5 also changes correspondingly.

  At this time, when the napkin 1 is viewed from the skin side, the region d, the region d, and the region e that appears to be the darkest color depending on the color of the back sheet 5 is the region d. The region d is a region between the inner end 2e of the side sheet 2 and the end 10e of the absorbent body 10. Therefore, when the color of the region d looks darkest, it becomes easy to visually recognize the boundary with the region b adjacent to the region d. As a result, it becomes easier to recognize the end 10 e of the absorber 10.

  Similarly, of the regions b, d, e, and f, the region that appears to be the darkest color depending on the color of the backsheet 5 is the region d. Further, the region d, which is the darkest color among the region b, the region d, the region e, the region f, and the region g is also the region d.

  In this way, when the color of the region d adjacent from the outside in the width direction of the end 10e of the absorber 10 is darker than the regions b, e, f, and g adjacent in the width direction, when viewed from the skin side. Since it becomes easy to visually recognize the end 10e of the absorber 10, it becomes easier to recognize the outline of the absorber 10. Accordingly, the wearer can know the configuration of the napkin 1 to be used in advance, and can wear it with peace of mind.

  Moreover, in this embodiment, when recognizing the edge 10e of the white absorbent body 10, by visually recognizing the region d in which the color of the backsheet 5 colored in pink is best seen, the region b and the most colored Although the visual recognition is facilitated by the difference in color from the dark area d, the present invention is not limited to this. For example, when the absorbent body 10 colored in green and the white backsheet 5 are used, the region D in FIG. 4 has the least number of members laminated in the thickness direction, and the white color of the backsheet 5 It will be the area that looks best and the area with the lightest color. Thus, the region d adjacent to the outer side in the width direction of the end 10e of the absorber 10 is adjacent to the region b and the outer side in the width direction with respect to the colored absorber 10 as described above. The difference in color of the region d can be easily recognized, and the outline of the absorber 10 can be easily recognized.

FIG. 6A is a diagram illustrating the individual package 100. FIG. 6B is a diagram illustrating the napkin 1 in which a part of the individual package 100 is developed. FIG. 6C is a diagram illustrating the napkin 1 further expanded from FIG. 6B. FIG. 6D is a diagram illustrating the napkin 1 further expanded from FIG. 6C. FIG. 6E is a diagram for explaining the napkin 1 further expanded from FIG. 6D. FIG. 6F is a diagram illustrating the napkin 1 obtained by removing the packaging material from FIG. 6E. In FIG. 6A-FIG. 6D, the external shape of the napkin 1 which can be visually recognized through the packaging material 50 is shown with the dotted line.

  FIG. 6A shows the individual package 100 in a state of being folded with the longitudinal folds Q1 and Q2 and the width folds P1 and P2 in FIG. At this time, since the packaging material 50 is white, the back sheet 5 is pink, so that the outer shape of the napkin 1 can be visually recognized through the packaging material 50. At this time, it is difficult to visually recognize the outline of the absorber 10 (the end 10e of the absorber 10).

  Subsequently, by pulling the tape 51, as shown in FIG. 6B, the second width fold line P2 is developed at the base point, and as shown in FIG. 6C, the first width fold line P1 is developed at the base point. Thereby, it will be in the state fully developed in the longitudinal direction. Even in these states, since the absorbent body 10 is covered with the packaging material 50, the back sheet 5, and the like, it is difficult to visually recognize the outline of the absorbent body 10 (the end 10e of the absorbent body 10).

  Further, by developing the second longitudinal fold Q2 as a base point, as shown in FIG. 6D, at least a part of the top sheet 3 is exposed. At this time, by providing the inner end 2e of the side sheet 2 outside the end 10e of the absorbent body 10, the end 10e of the absorbent body 10 can be easily seen and the contour of the absorbent body 10 can be recognized more.

  Finally, by developing the first longitudinal fold Q1 as a base point, the entire shape of the napkin 1 can be visually recognized as shown in FIG. 6E, and then the packaging material 50 is removed as shown in FIG. 6F. Thus, the napkin 1 can be put on.

  As shown in FIG. 6E and FIG. 6F, not only the folds P1, P2, Q1, and Q2 are all expanded, but also a part of the folds (P1, P2,. Q2) Even in a state where some folds are not expanded (Q1), the outline of the absorber 10 can be visually recognized. Therefore, for example, even if the wearer removes the packaging material 50 from the state of FIG. 6D without going through the state of FIG. 6E, the wearer is in the state of FIG. Since at least a part of the contour can be visually recognized, it becomes possible to recognize the configuration of the napkin 1 scheduled to be worn in advance.
