Description

  The present invention relates to an absorbent article that absorbs urine such as disposable diapers.

  Conventionally, a three-piece disposable diaper 1 as shown in Patent Document 1 has been used as an absorbent article that absorbs urine. FIG. 1A is a schematic perspective view of a diaper 1 in a worn state, and FIG. 1B is a schematic plan view of the diaper 1 developed from a portion 1s, 1s that contacts the wearer's flank and viewed from the non-skin side. FIG. The three-piece diaper 1 is roughly divided into three parts. That is, the diaper 1 has an absorbent main body 10 that is applied to the wearer's crotch and absorbs urine as a first part, and a ventral belt member 30a that covers the abdomen of the wearer as a second part. And the back part belt member 30b which covers a wearer's back side part as a 3rd part. Then, in the state where the abdominal band member 30a and the back band member 30b are arranged in parallel with a space between each other, the absorbent main body 10 is stretched between them, while the longitudinal length of the absorbent main body 10 is increased. The end portions 10ea and 10eb in the direction are covered and fixed to the corresponding nearest band members 30a and 30b from the non-skin side of the absorbent main body 10, whereby the appearance of the unfolded diaper 1 is viewed in plan view. It is substantially H-shaped.

  In addition, the longitudinal direction of the absorptive main body 10 is along the vertical direction of the diaper 1, and each strip | belt member 30a, 30b is extended and arrange | positioned in the horizontal direction orthogonal to this vertical direction. Further, the direction perpendicular to both the vertical direction and the horizontal direction (in FIG. 1B, the direction penetrating the paper surface) is the thickness direction of the diaper 1.

  A plurality of elastic members 35 s 1, 35 s 2, etc., such as rubber thread, are joined and fixed along the same direction in the lateral direction while being stretched in the lateral direction, so that each of the belt members 30 a, 30 b , Lateral elasticity is imparted. Further, of the band members 30a and 30b, the portions 30ac and 30bc to which the end portions 10ea and 10eb of the absorbent main body 10 are fixed are the center portions 30ac and 30bc in the lateral direction. 30bc is provided with illustration sheets 40, 40 such as a picture of an animal (not shown) so as to be visible from the non-skin side of the diaper 1.

  Here, when the stretchability as described above is imparted to the central portions 30ac, 30bc, the illustration sheets 40, 40 of the central portions 30ac, 30bc are contracted in the lateral direction to cause wrinkles, and the illustration sheets 40 40 becomes difficult to see. Therefore, among the plurality of elastic members 35s1, 35s2,... Provided on the belt members 30a, 30b, the elastic members 35s2, 35s2,... Traversing the illustration sheet 40 in the lateral direction are divided at the position of the illustration sheet 40. 1B, the elastic member crossing the illustration sheet 40 is not substantially present, or the elastic member (not shown) crossing the illustration sheet 40 is cut into a discontinuous state. Thus, the stretchability of the portions 30ac, 30bc corresponding to the illustration sheet 40 in the belt members 30a, 30b is lowered. However, the elastic members 35s1, 35s1,... That do not cross the illustration sheet 40 in the lateral direction are basically not cut and the elastic members 35s1, 35s1,. It is left in the form of And thereby, the problem is not produced about the fitting property of the diaper 1. FIG.

  However, the consumer who sees the elastic members 35s2, 35s2,. For example, it is anxious whether the diaper 1 that has absorbed urine has sufficient elasticity so as not to slip down.

  Such anxiety is considered to be reduced by looking at the elastic members 35s1, 35s1,... That are not cut, that is, the elastic members 35s1, 35s1,. . However, since the nonwoven fabric is generally used for the back sheet member 15 that forms the non-skin side surface of the absorbent main body 10 and each of the band members 30a and 30b, the color is often white, and generally the elastic member 35s1, Since the rubber thread is used even in the case of 35 s 2..., The color is often white, that is, they are often the same color. Therefore, the elastic members 35s1, 35s2,... Are hardly visible like the protective color, and as a result, the consumer is difficult to notice the presence of the elastic members 35s1, 35s1,. The anxiety about the fit of the diaper 1 may not be wiped out.

  The present invention has been made in view of the conventional problems as described above, and its purpose is to suppress the occurrence of wrinkles in the second colored portion such as an illustration sheet provided in the central portion in the lateral direction of the belt member.

=== This Embodiment ===
FIG. 2 is a schematic perspective view of a three-piece type disposable diaper 1 as an example of the absorbent article of the present embodiment. FIG. 3 is a schematic plan view of the unfolded diaper 1 as viewed from the skin side, and FIG. 4 is a schematic perspective view of the diaper 1 as viewed from the non-skin side. 5A is an AA sectional view and a CC sectional view in FIG. 3, and FIG. 5B is a BB sectional view in FIG.

  As shown in FIGS. 3, 5A, and 5B, the diaper 1 has a vertical direction, a horizontal direction, and a thickness direction as three directions orthogonal to each other. Moreover, since the diaper 1 is a so-called three-piece type, it has three parts 10, 30a, 30b. That is, this diaper 1 has an absorbent main body 10 that is applied to the wearer's crotch portion and absorbs urine as a first component, and a ventral belt member that covers the ventral portion of the wearer as a second component. 30a, and the back part belt member 30b which covers the back side part of the same wearer as the third part. In the deployed state of FIG. 3, the abdomen side band member 30a and the back side band member 30b are arranged in parallel with a space between each other, while the absorbent main body 10 is stretched between them. End portions 10ea and 10eb in the longitudinal direction of the absorbent main body 10 are bonded and fixed to the nearest belt members 30a and 30b, respectively, and the external shape thereof is substantially H-shaped in plan view. Then, from this state, the absorbent main body 10 is folded in half with the substantially central portion C10 in the longitudinal direction as the folding position, and the band members 30a, 30b facing each other in the folded state are When the belt members 30a and 30be are connected to each other at the end portions 30ae and 30be (that is, the end portions 30ae and 30be in the lateral direction), the belt members 30a and 30b are connected in an annular shape, and as shown in FIG. It becomes the diaper 1 of the wearing condition in which the trunk periphery opening 1HB and a pair of leg periphery opening 1HL and 1HL were formed.

  In addition, various connection structures are employable as a connection structure which connects the above-mentioned band members 30a and 30b. For example, if a non-removable connection structure such as welding is used, the pant-type diaper 1 can be formed. On the other hand, if a detachable connection structure such as a fastening tape member (not shown) is used, an open type diaper 1 can be used. Can be a diaper. Incidentally, in this example, the former connection structure is used, and thus the diaper 1 is a pants type.

In the following description, the vertical direction, the horizontal direction, and the thickness direction of the diaper 1 are simply referred to as “vertical direction”, “horizontal direction”, and “thickness direction”, respectively. Regarding the thickness direction, the side in contact with the wearer is also referred to as “skin side”, and the opposite side is also referred to as “non-skin side”.
Hereinafter, the three components 10, 30a and 30b of the diaper 1 will be described with reference to FIGS. 2 to 5B.
As shown in FIGS. 3 and 5B, the absorbent main body 10 includes an absorbent core 11 formed by molding a pulp fiber as an example of a liquid absorbent fiber into a substantially hourglass shape in a plan view as an example of a predetermined shape, A top sheet member 13 that covers the absorbent core 11 from the skin side of the core 11, and a back sheet member 15 that covers the absorbent core 11 from the non-skin side of the core 11 and forms the exterior of the absorbent main body 10. Yes. In addition, this absorptive core 11 may contain, for example, a superabsorbent polymer as a liquid absorptive granule, or includes a liquid absorptive material other than a liquid absorptive fiber and a liquid absorptive granule. May be. Moreover, the absorptive core 11 may be coat | covered with liquid permeable sheets (not shown), such as tissue paper.

  The top sheet member 13 is, for example, a liquid-permeable nonwoven fabric having a larger planar size than the absorbent core 11. Further, as shown in FIG. 5B, the back sheet member 15 is also a sheet having a larger plane size than the absorbent core 11, and as an example, a liquid-impermeable leak-proof sheet 15a such as polyethylene or polypropylene, and a nonwoven fabric are used. For example, a sheet 15 having a two-layer structure in which an exterior sheet 15b such as the above is bonded. And in the state which inserted the absorptive core 11 between these back surface sheet members 15 and the top surface sheet member 13, in the part which protrudes outside from the four sides of the absorptive core 11, the leak-proof sheet 15a of the back surface sheet member 15 and The top sheet member 13 is bonded together in a frame shape, whereby the absorbent main body 10 is generally formed.

  In some cases, as shown in FIGS. 2, 3, and 5B, a so-called three-dimensional gather LSG and leg gathers LG may be formed by the exterior sheet 15b. The three-dimensional gather LSG is a leak-proof wall portion LSG provided upright at each end portion in the lateral direction of the top sheet member 13, while the leg-hole gathers LG are the leg-hole openings 1 HL and 1 HL of the diaper 1. It is the expansion-contraction part LG formed in. The exterior sheet 15b will be described in detail. First, as shown in FIG. 5B, the lateral dimension of the exterior sheet 15b is sufficiently larger than the leak-proof sheet 15a. That is, the exterior sheet 15b is made of the leak-proof sheet 15a. It protrudes laterally from both lateral sides. Then, the protruding portion 15bf is folded back to the lateral center with the position forming the lateral end 10es of the absorbent body 10 being the folded position, and the rubber thread along the longitudinal direction in the vicinity of the folded position. An elastic member 17 such as the like is fixed under extension in the vertical direction, thereby forming the above-mentioned leg gathers LG. Further, the folded portion 15bg further extends toward the center in the lateral direction, and is joined to the end portion at a position covering the lateral end portion of the top sheet member 13. And the part joined to this end part functions as the base end part LSGb of the three-dimensional gather LSG, that is, the part on the tip side in the lateral direction further than the base end part LSGb serves as the free end part LSGf. 13 can stand up. In addition, an elastic member 18 such as rubber thread is fixed to the front end portion of the free end portion LSGf along the vertical direction under extension. Therefore, the absorbent main body 10 bends in the vertical direction so that the surface sheet member 13 side becomes the inner peripheral side by the shrinkage in the longitudinal direction of the elastic member 18. Thus, the free end portion LSGf contracts in the vertical direction and stands up from the top sheet member 13, whereby the free end portion LSGf functions as a three-dimensional gather LSG.

  Although not shown, depending on the case, liquid permeation of tissue paper or the like as a second sheet may be provided between the top sheet member 13 and the absorbent core 11 or between the back sheet member 15 and the absorbent core 11. A sex sheet may be interposed.

  As shown in FIG. 3, the ventral belt member 30 a and the back belt member 30 b are both sheet members having a substantially rectangular shape in a plan view made of a flexible sheet such as a nonwoven fabric. Here, as shown in FIG. 5A and FIG. 5B, the band members 30 a and 30 b are formed by joining the nonwoven fabrics 31 and 32 in a two-ply manner, and the band members 30 a and 30 b are respectively central portions in the lateral direction. 30ac and 30bc, while covering the longitudinal ends 10ea and 10eb of the absorbent main body 10 from the non-skin side of the absorbent main body 10, the central portions 30ac and 30b of the band members 30a and 30b are covered with the respective end portions 10ea and 10eb. 30bc are overlapped and joined.

  The two nonwoven fabrics 31 and 32 do not have to be the same size. For example, FIG. 6 as an explanatory diagram shows a cross-sectional view taken along the line VI-VI in FIG. 3 in the case of such a configuration. That is, in FIG. 6, the sizes in the longitudinal direction are different so that the nonwoven fabric 31 positioned on the non-skin side in the thickness direction protrudes beyond the nonwoven fabric 32 positioned on the skin side in the longitudinal direction. However, you may do this. In this case, as shown in FIG. 6, in the non-skin side nonwoven fabric 31, the portion 31 f protruding from the skin side nonwoven fabric 32 in the longitudinal direction is the longitudinal end of the skin side nonwoven fabric 32. It is folded back to the center in the vertical direction with the position near the edge as the folding position. The folded portion 31g is overlapped and joined to the nonwoven fabric 32 on the skin side. In this case, a part of the longitudinal end portions 10ea and 10eb of the absorbent main body 10 may be covered from the skin side of the absorbent main body 10 with the folded portion 31g.

  Here, the superposition of the absorbent main body 10 on the central portions 30ac and 30bc of the band members 30a and 30b described above does not overlap the vertical end portions 30ae2 and 30be2 of the band members 30a and 30b. In addition, the absorbent main body 10 is overlapped with the portions 30ac2 and 30bc2 on the center side in the vertical direction with respect to the end portions 30ae2 and 30be2. As a result, the end portions 30ae2 and 30be2 in the vertical direction of the band members 30a and 30b are formed as portions 30ae2 and 30be2 where the absorbent main body 10 does not overlap at all over the entire length in the horizontal direction. Note that the non-overlapping portions 30ae2 and 30be2 are portions constituting the waist opening 1HB (FIG. 2) of the diaper 1. Therefore, the elastic members 35U described later are provided in the portions 30ae2 and 30be2 in the portions 30ae2 and 30be2. It is provided continuously over substantially the entire length in the lateral direction. Further, in this example, the longitudinal sizes La and Lb of the portions 30ae2 and 30be2 where the absorbent main body 10 does not overlap are larger in the back band member 30b than in the ventral band member 30a (Lb> La), that is, as a whole, the absorbent main body 10 is arranged more biased toward the ventral band member 30a than the back band member 30b. And although the smooth absorbability of urine is ensured by this, it is not restricted to this at all. For example, the magnitude relationship between the magnitudes La and Lb may be reversed (that is, Lb <La), or the magnitudes La and Lb may be equal to each other (that is, Lb = La). .

  As shown in FIG. 3, FIG. 5A, and FIG. 5B, a plurality of elastic members 35, such as rubber thread, are provided along the lateral direction between the two nonwoven fabrics 31 and 32 relating to the band members 30a and 30b. 35 ... are inserted and fixed to the non-woven fabrics 31 and 32 while being stretched in the lateral direction, whereby the belt members 30a and 30b are given stretchability in the lateral direction. In addition, the plurality of elastic members 35, 35... Are provided side by side in the vertical direction with an interval in the vertical direction. These elastic members 35, 35... Are provided on both the abdominal band member 30a and the back band member 30b, respectively, but the detailed specifications such as the thickness and number of the elastic members 35, 35. The basic configuration is generally the same as each other. Therefore, in the following, only the elastic members 35, 35 of the ventral band member 30a will be described on behalf of the elastic members 35, 35 of the ventral band member 30a and the back band member 30b. Description of the elastic members 35, 35. In connection with this, in FIG. 3, the elastic member 35 of the back | dorsal band member 30b is also shown using the same code | symbol 35 as the elastic member 35 of the ventral | abdominal band member 30a. This also applies to all configurations related to the back band member 30b. For example, the illustration sheet 40 and the coloring part 50, which will be described later, are also given the same reference numerals as the illustration sheet 40 and the coloring part 50, etc. of the ventral band member 30a, and the illustration sheet 40, the coloring part 50, etc. related to the back side band member 30b The description of is omitted.

  In the following, for convenience of explanation, as shown in FIG. 4, the belt member 30a is divided into three regions AU, AM, AD in the vertical direction, and each of the three regions AU, AM, AD arranged in the vertical direction. The ADs are referred to as “upper region AU”, “middle region AM”, and “lower region AD” from the vertical end to the center. As can be seen with reference to FIG. 4, each of the areas AU, AM, AD is a band-like area along the horizontal direction.

  The upper region AU is a part constituting the waist opening 1HB of the diaper 1, and the region AU is a region where the absorbent main body 10 is not overlapped at all over the entire length in the lateral direction. In the upper area AU, the elastic member 35U (35) is continuously extended over substantially the entire length from one end to the other end in the horizontal direction in the area AU, while being stretched in the horizontal direction. It is fixed. Therefore, the upper region AU is provided with a lateral stretchability over substantially the entire length in the lateral direction based on the elastic member 35U (35), and this stretchability is the stretch of the waist opening 1HB of the diaper 1. It becomes sex.

The middle region AM (corresponding to the first region) is a region where the longitudinal end portion 10ea of the absorbent main body 10 is overlapped and fixed to the lateral central portion AMc. More precisely, a portion 10n of the absorbent main body 10 where the absorbent core 11 does not exist is overlapped and fixed to the central portion AMc of the region AM. Note that the absorbent main body 10 is not superimposed on the portions AMe and AMe located on both sides of the central portion AMc in the middle region AM.
Here, in the middle region AM, the elastic member 35M (35) extends in the lateral direction while being continuously disposed over substantially the entire length from one end to the other end in the lateral direction in the region AM. It is fixed with. And thereby, the elasticity of the horizontal direction is provided to the middle area AM over the substantially entire length in the horizontal direction based on the elastic member 35M (35). Moreover, in the part which opposes the said center area | region AM among the absorptive main bodies 10, in order for a consumer to make it easy to visually recognize the elastic member 35M (35) of the center area | region AM from the non-skin side of the diaper 1, it is strip | belt shape. A coloring unit 50 (FIG. 7) is provided, which will be described later.

The lower region AD (corresponding to the second region) is a region where the portion 10p of the absorbent main body 10 where the absorbent core 11 is present is overlapped and fixed to the lateral central portion ADc. In the lower region AD, the absorbent main body 10 is not superimposed on the portions ADe and ADe located on both sides of the central portion ADc.
Further, in each of the portions ADe, ADe, the elastic member 35D (35) is arranged in the lateral direction while being continuously arranged over substantially the entire length from one end portion to the other end portion in the lateral direction in the portion ADe. It is fixed under extension. Thereby, the stretchability in the lateral direction is given to each of the portions ADe, ADe over substantially the entire length in the lateral direction.
On the other hand, the elastic member 35D (35) is discontinuously arranged in the lateral direction in the central portion ADc. Specifically, in this example, the end portions of the elastic member 35D (35) are located at both end portions ADce and ADce in the lateral direction of the central portion ADc. The elastic member 35D (35) does not exist in the central portion ADcc in the horizontal direction. Therefore, in the central portion ADc, the elastic member 35D (35) is disposed discontinuously in the horizontal direction. When the elastic member 35D (35) is not present in the central portion ADcc of the central portion ADc as described above, the central portion ADcc is hardly provided with stretchability. Shrinkage is suppressed. And in connection with this, since the shrinkage | contraction of the absorptive core 11 is also suppressed, generation | occurrence | production of the wrinkle of the core 11 is also prevented, and the skin side surface of the core 11 is maintained substantially flat. As a result, liquid absorption inhibition of the core 11 can be effectively prevented, and urine leakage due to wrinkles can also be prevented.

  As shown in FIG. 4, an illustration sheet 40 (corresponding to a second colored portion) on which an illustration (not shown) such as an animal is formed is provided in the central portion ADc of the lower region AD. For the same reason, the generation of wrinkles in the illustration sheet 40 is also suppressed. Therefore, the illustration becomes easy to see.

  In this example, as shown in FIG. 5B, the band member 30a is formed by overlapping two nonwoven fabrics 31 and 32, and the illustration sheet 40 is between the two nonwoven fabrics 31 and 32 stacked. Although it is inserted and fixed with an adhesive or the like, it is not limited to this. For example, it may be fixed to the non-skin side surface of the band member 30a without being inserted, and may be further fixed to the skin side surface of the band member 30a. Incidentally, when inserted between the non-woven fabrics 31 and 32, or when being fixed to the skin side surface of the band member 30a, the illustration of the illustration sheet 40 is the non-skin-side non-woven fabric 31 ( The non-woven fabric 31 (32) can be seen through the inter-fiber gap 32), and the illustration can be visually recognized from the non-skin side in the thickness direction through the non-woven fabric 31 (32). Moreover, as a material of this illustration sheet 40, although resin films, such as a polyethylene film or a polypropylene film, can be illustrated, for example, if it is a flexible sheet | seat and can form an illustration on a non-skin side, it will not restrict to this at all . For example, you may use a nonwoven fabric and a woven fabric.

  By the way, as described above, a consumer who sees the elastic member 35D (35) discontinuously disposed in the lower region AD (FIG. 4) of the band member 30a may feel anxious about the fit of the diaper 1. is there. Such anxiety is considered to be alleviated by looking at the elastic member 35 continuously disposed over the substantially entire length of the belt member 30a in the lateral direction. For example, in this example, in the upper region AU and the middle region AM, there are elastic members 35 (35U, 35M) arranged in such a manner. Therefore, it is considered that such anxiety can be resolved by looking at the elastic members 35U and 35M in the upper region AU and the middle region AM.

  However, as with many diapers, the diaper 1 in the example of FIG. 5A also has a white sheet on the exterior sheet 15b and the leak-proof sheet 15a of the back sheet member 15 forming the non-skin side of the absorbent body 10. A nonwoven fabric and a white film are used, white nonwoven fabrics 31 and 32 are used for the band member 30a, and white thread rubber is used for the elastic member 35 (35U, 35M). Therefore, the elastic member 35 (35U, 35M) in the upper region AU and the middle region AM of the belt member 30a in FIG. 4 is difficult to be visually recognized like a protective color, and the consumer is difficult to notice the presence.

  Therefore, in the present embodiment, as shown in FIG. 5A, the elastic member 35 </ b> M is used to make the elastic member 35 </ b> M (35) of the middle region AM (FIG. 4) of the band member 30 a easily visible from the non-skin side of the diaper 1. In the absorptive main body 10 located on the skin side in the thickness direction from (35), the colored portion 50 corresponding to the middle region AM is colored by coloring the portion corresponding to the middle region AM with a color other than white. Is forming. Thus, the colored portion 50 can be shown as a background of the elastic member 35M (35) located in the middle region AM (see, for example, FIG. 7), and as a result, the elastic member 35M in the middle region AM. The visibility of (35) is improved. The details will be described below.

FIG. 7 is a schematic enlarged view of the ventral band member 30a when viewed from the non-skin side of the diaper 1.
As shown in FIG.7 and FIG.5A, in this example, the coloring part 50 (equivalent to a 1st coloring part) is the non-skin side surface of the leak-proof sheet 15a which concerns on the back surface sheet member 15 which the absorptive main body 10 comprises. Is provided in a portion facing the middle region AM (see the hatched portion in FIG. 7). Therefore, as shown in FIG. 7, when the elastic member 35 </ b> M (35) of the middle region AM is viewed from the non-skin side of the diaper 1, the elastic member 35 </ b> M is attached to the colored portion 50 (hatched portion in FIG. 7). Looks like they overlap. Accordingly, the elastic member 35M can be viewed from the non-skin side of the diaper 1 while using the colored portion 50 as the background of the elastic member 35M. As a result, the elastic member 35M is continuously provided in the lateral direction. It becomes easy to visually recognize the state of being.

  Further, as shown in FIG. 7, the colored portion 50 is formed in a band shape along the horizontal direction. Specifically, the colored portion 50 is formed in a strip shape having a length extending over the entire length in the lateral direction of the leak-proof sheet 15a (FIG. 5A). Further, as shown in FIG. It is said to be AM. Therefore, the visibility is improved with respect to all (three in FIG. 7) elastic members 35M, 35M, and 35M located in the middle region AM. Further, as can be seen from the above, in the example of FIG. 5A, the colored portion 50 is provided continuously over the entire length in the horizontal direction of the leak-proof sheet 15a, so that the elastic member 35M is continuous in the horizontal direction. It is possible to make the state of being visible with certainty. However, the colored portion 50 only needs to be the background of at least one elastic member 35M among the elastic members 35M, 35M... Located in the middle region AM. It may be smaller than the plane size, i.e., may be within the middle area AM.

  Incidentally, in the example of FIG. 5A, the sheet member positioned on the non-skin side in the thickness direction with respect to the leakage preventing sheet 15a provided with the colored portion 50 is the exterior sheet 15b of the back sheet member 15 of the absorbent main body 10. And the belt member 30a, both of the exterior sheet 15b and the belt member 30a are made of nonwoven fabric. Therefore, about the coloring part 50 of the leak-proof sheet 15a, it can be visually recognized at least from the non-skin side of the diaper 1 in a form that allows the exterior sheet 15b and the band member 30a to pass through. The part 50 can function effectively as a background of the elastic member 35M.

  In the example of FIG. 7, the illustration sheet 40 is provided in the lower area AD of the band member 30a, that is, not provided in the middle area AM. Therefore, it is effectively avoided that the illustration sheet 40 overlaps the colored portion 50 when viewed from the non-skin side of the diaper 1, and as a result, it is also effective to make it difficult to visually recognize the colored portion 50 from the non-skin side. It is prevented.

  Furthermore, the form in which the illustration sheet 40 is not provided in the middle region AM and the coloring portion 50 is provided in the middle region AM as described above can be rephrased as follows. That is, it can be said that “when viewed from the non-skin side of the diaper 1, the colored portion 50 has a portion 50 n that does not overlap the illustration sheet 40”. In this case, when viewed from the same non-skin side, the elastic member 35M in the middle region AM overlaps the portion 50n of the colored portion 50 that does not overlap the illustration sheet 40. Therefore, it is possible to effectively prevent the illustration sheet 40 from being wrinkled due to the elastic member 35M provided over substantially the entire length in the lateral direction. It can be made easier to see.

  Moreover, in this example, each color of the exterior sheet 15b and the leak-proof sheet 15a forming the back sheet member 15 of the absorbent main body 10, the elastic member 35 (35U, 35M, 35D), and the belt member 30a (30b) is all. As an example of a color different from white because of the white color, the color of the colored portion 50 is blue, but the present invention is not limited to this. For example, red or green may be used, or colors other than these may be selected. That is, any color other than white may be selected. In addition, when at least one color of the exterior sheet 15b, the leak-proof sheet 15a, the elastic member 35, and the belt member 30a (30b) is a color other than white, coloring is performed according to the combination of these colors. The color of the part 50 is appropriately selected. That is, the color of the coloring portion 50 is selected so that the elastic member 35M (35) is conspicuous when the elastic member 35M (35) is viewed from the non-skin side of the diaper 1. For example, the color of the coloring part 50 may be set to a color different from both the colors of the elastic member 35M (35) and the leak-proof sheet 15a, or the elastic member 35M (35), the leak-proof sheet 15a, and the exterior sheet. The color of the colored portion 50 may be set to a color different from the three colors 15b.

  Incidentally, the definition of the same color here is as follows. First, as a premise, here, it is assumed that the expression of all colors can be expressed by a combination of values selected from 0 ° to 360 ° for each of brightness, hue, and saturation. Then, with respect to the two colors to be determined whether or not they are the same color, the brightness, hue, and saturation values are compared with each other, and as a result of the comparison, the brightness, hue , And saturation values are within the range of ± 5 ° of each other's color values, they are considered to be “same color” and are one of the lightness, hue, and saturation values. However, if it is not within the range of ± 5 °, it is regarded as “different colors”.

  Moreover, in the example of FIG. 5A and FIG. 7, although the coloring part 50 was formed by coloring directly to the non-skin side surface of the leak-proof sheet 15a, it is not restricted to this at all. For example, the colored part 50 may be provided by joining another colored sheet to the leak-proof sheet 15a. Furthermore, the colored portion 50 may be formed on the exterior sheet 15b instead of the leak-proof sheet 15a. In addition, about the formation method of the coloring part 50 in that case, the method similar to the case of the leak-proof sheet | seat 15a can be used. That is, the colored portion 50 may be formed by directly coloring the non-skin side surface of the exterior sheet 15b, or the colored portion 50 may be formed by joining another colored sheet to the exterior sheet 15b. good.

  By the way, as can be seen from the foregoing, the colored portion 50 is provided in a portion of the absorbent main body 10 that faces the middle region AM. That is, as shown in FIG. 7, the absorbent main body 10 is provided in the portion 10 n where the absorbent core 11 does not exist. On the other hand, an elastic member 35M (35) that is continuous in the lateral direction to make the colored portion 50 stand out is also provided in the middle region AM. And this elastic member 35M (35) shrinks the absorptive main body 10 in the lateral direction. Here, as is clear from the above, the central region AM provided with the elastic member 35M (35) is absorbent. It is a portion 10 n of the main body 10 where the absorbent core 11 does not exist. Accordingly, the occurrence of wrinkles in the absorbent core 11 due to the elastic member 35M (35) is effectively suppressed, and the skin side surface of the absorbent core 11 is easily maintained substantially flat. This also contributes effectively to prevention of liquid absorption inhibition of the absorbent core 11.

=== Other Embodiments ===
As mentioned above, although embodiment of this invention was described, said embodiment is for making an understanding of this invention easy, and is not for limiting and interpreting this invention. Further, the present invention can be changed or improved without departing from the gist thereof, and needless to say, the present invention includes equivalents thereof. For example, the following modifications are possible.

  In the above-mentioned embodiment, although illustrated about the case where the colored part 50 as an example of a 1st colored part is provided in the part which opposes the middle area | region AM of the abdominal side belt member 30a among the absorptive main bodies 10, it is not restricted to this at all Absent. That is, you may provide the same coloring part 50 in the part which opposes the center area | region AM of the back | bag side band member 30b among the absorptive main bodies 10 of FIG. And if it does in this way, elastic member 35M (35) located in middle part area AM of back side belt member 30b, ie, elastic member 35M (disposed continuously over the full length of the transverse direction of middle part AM) ( 35) can be surely seen by the consumer, and this can alleviate the consumer's anxiety that the diaper 1 will be displaced downward after a stool.

In the above-described embodiment, the elastic member 35D (35) of the central portion ADc is used for the purpose of reducing the stretchability of the central portion ADc in the lateral direction of the lower region AD where the illustration sheet 40 is provided in the belt member 30a (30b). It was discontinuous. As an example of this discontinuous elastic member 35D, as shown in FIG. 7, elastic members 35M (35) are present at both ends ADce and ADce in the lateral direction of the central portion ADc. The configuration in which the elastic member 35D (35) is not present is illustrated in the lateral central portion ADcc of the central portion ADc, but is not limited thereto.
That is, if the elastic member 35D is discontinuously arranged in the central portion ADc in order to reduce the stretchability of the central portion ADc of the lower region AD, the elastic member 35D is further provided in the central portion ADcc of the central portion ADc. May exist. FIG. 8 is a schematic plan view for explaining an example thereof. In FIG. 8, the non-skin side non-woven fabric 31 of the belt member 30a is removed, and the elastic member 35 (35U, 35M, 35D) is exposed to the outside. In the example of FIG. 8, the elastic member 35D located at the central portion ADcc is in a state of being finely divided. And if it is in this finely cut state, elastic member 35D will no longer give stretchability to central portion ADcc. Therefore, as long as the elastic member 35D is in such a state, it may exist in the central portion ADcc. The length of the elastic member 35D in a finely cut state is, for example, greater than 0 mm and not greater than 5 mm, and more desirably greater than 0 mm and not greater than 3 mm. However, when the elastic member 35D is cut into pieces, the appearance deteriorates. Therefore, it is desirable that the elastic member 35D is not present in the central portion ADcc (FIG. 7).

  In the above-described embodiment, the elastic member 35D (35) is discontinuously disposed in the central portion ADc in the lateral direction in the lower region AD of FIG. 4, but this is not a limitation. For example, the elastic member 35D (35) may not be disposed in the center portion ADc. That is, in the example of FIG. 4 described above, the end portion of the elastic member 35D (35) is applied to the center portion ADc at the position of each end portion ADce, ADce in the horizontal direction. However, the elastic member 35D (35) The end portion of the central portion ADc may not be located at the position of the end portion ADce of the central portion ADc.

  In the above-described embodiment, the strip-shaped colored portion 50 extending in the lateral direction is provided on the leak-proof sheet 15a as an example of the first colored portion 50, but the shape of the colored portion 50 is not limited to this. For example, a horizontal stripe shape in which a plurality of linear portions along the horizontal direction are arranged in the vertical direction may be used, or a vertical stripe shape in which a plurality of linear portions along the vertical direction are arranged in the horizontal direction may be used. However, it may be an oblique stripe shape in which a plurality of straight portions facing the direction between the vertical direction and the horizontal direction are arranged. Furthermore, it may be other than such a geometric pattern, for example, a character, a picture, a symbol, or the like. Moreover, as a coloring method to the leak-proof sheet 15a for forming the coloring part 50, printing methods, such as flexographic printing, inkjet printing, and screen printing, can be illustrated.

  In the above-described embodiment, the material of the exterior sheet 15b and the band members 30a and 30b is a non-woven fabric, but is not limited to the non-woven fabric. That is, if the coloring part 50 of the leak-proof sheet 15a is visible from the non-skin side of the diaper 1 in a form that allows the exterior sheet 15b and the band members 30a and 30b to pass through, a material other than the nonwoven fabric can be used without any problem. . For example, a woven fabric or a sheet member other than the woven fabric may be used. Incidentally, the exterior sheet 15b may be omitted, and in that case, the leak-proof sheet 15a forms the exterior of the absorbent main body 10.

  In the above-described embodiment, illustrations (not shown) of animals and the like are formed on the illustration sheet 40, but the illustrations are not limited to animals and the like. For example, it may be a picture other than an animal, a letter or a symbol, or a pattern. That is, as long as the design of the diaper 1 can be improved, it may be formed on the illustration sheet 40. It should be noted that the pattern formation on the illustration sheet 40 can also be performed by the printing method described above.

  In the above-described embodiment, the rubber thread is exemplified as the elastic member 35 (35U, 35M, 35D), but the invention is not limited thereto. For example, a belt-like rubber may be used as the elastic member 35, a belt-like non-woven fabric having elasticity or a belt-like resin film having elasticity.
