Conventionally, a three-part disposable diaper 1 of the type described in Patent Document 1 has been used as an absorbent article for absorbing urine. 1A is a schematic perspective view of the diaper 1 in a worn state, and FIG. 1B is a schematic plan view showing the diaper 1 after being cut off from the portion 1s and 1s that abuts the side of the wearer, and is viewed from the non-skin side. The 3-part diaper 1 is roughly divided into three parts. In other words, the diaper 1 has an absorbent body 10 that abuts against the wearer's crotch portion to absorb urine, and the second member has a belly covering the wearer's ventral portion. The side belt member 30a has a back side belt member 30b covering the back side portion of the wearer in the third part. Further, the front side belt member 30a and the back side belt member 30b are arranged in a substantially parallel arrangement with each other spaced apart from each other, and the absorbent body 10 is laid between the same, and the longitudinal direction of the absorbent body 10 is Each of the end portions 10ea, 10eb is covered from the non-skin side of the absorbent body 10 and fixed to the respective closest belt members 30a, 30b, whereby the expanded shape The appearance of the diaper 1 of the state is formed into a slightly H-shaped shape in plan view.

Further, the longitudinal direction of the absorbent body 10 is along the longitudinal direction of the diaper 1, and the respective belt members 30a, 30b are arranged to extend in the lateral direction orthogonal to the longitudinal direction. Moreover, the direction orthogonal to both the longitudinal direction and the lateral direction (the direction which penetrates the paper surface in FIG. 1B) becomes the thickness direction of the diaper 1.

In the respective belt members 30a and 30b, a plurality of elastic members 35s1, 35s2, ... such as silk rubber are joined and fixed in this direction in the lateral direction, whereby the belt members 30a and 30b are provided with lateral stretchability. Further, in the belt members 30a and 30b, the portions 30ac and 30bc of the end portions 10ea and 10eb of the absorbent body 10 are fixed to the central portions 30ac and 30bc in the lateral direction, but the diaper 1 is provided in the central portions 30ac and 30bc. The illustration sheets 40 and 40 such as an animal picture (not shown) that is visible on the non-skin side.

===This embodiment ===

Fig. 2 is a schematic perspective view of a three-part disposable disposable diaper 1 as an example of the absorbent article of the embodiment. Fig. 3 is a schematic plan view of the diaper 1 viewed from the skin side in an unfolded state, and Fig. 4 is a non-skin A schematic perspective view of the diaper 1 is viewed from the side. 5A is a cross-sectional view taken along line A-A and a cross-sectional view taken along line C-C in FIG. 3, and FIG. 5B is a cross-sectional view taken along line B-B in FIG.

As shown in FIGS. 3, 5A, and 5B, the diaper 1 has three directions in which the longitudinal direction and the lateral direction and the thickness direction are orthogonal to each other. Moreover, since the diaper 1 is a so-called three-part type, it has three parts 10, 30a, and 30b. In other words, the diaper 1 has an absorbent main body 10 that absorbs urine in contact with the crotch portion of the wearer as a first component, and has a front side belt member 30a that covers the abdominal side portion of the wearer as a second part. The back side belt member 30b covering the back side of the wearer is provided as a third part. Further, in the unfolded state of Fig. 3, the abdominal side belt member 30a and the back side belt member 30b are arranged in a substantially parallel arrangement with a space therebetween, and the absorbent body 10 is laid between the same, and the absorbent body is placed. The respective end portions 10ea and 10eb of the main body 10 in the longitudinal direction are joined and fixed to the closest belt members 30a and 30b, and the outer shape thereof is slightly H-shaped in plan view. In this state, the absorbent body 10 is folded in half at a substantially central portion C1 in the longitudinal direction thereof, and the belt members 30a and 30b that face each other in the folded state must be in contact with each other. When the portions 30ae and 30be of the flank (that is, the respective end portions 30ae and 30be in the lateral direction) are connected, the belt members 30a and 30b are connected to each other in a ring shape, thereby forming the same as shown in FIG. The diaper 1 in the wearing state of the waist opening 1HB and the pair of leg-openings 1HL and 1HL.

Further, various connection structures can be employed to connect the above-described connection structures of the belt members 30a and 30b. And, for example, if you use fusion The diaper 1 of the shorts type can be formed as the detachable detachable structure, and the detachable diaper can be formed by using a detachable connection structure such as a buckle member (not shown). Moreover, in this example, the former connection structure is used, and the diaper 1 becomes a pants type.

In the following description, only the longitudinal direction, the lateral direction, and the thickness direction of the diaper 1 are referred to as "longitudinal direction", "lateral direction", and "thickness direction". In addition, in 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 FIG. 3 and FIG. 5B, the absorbent body 10 is formed by molding a pulp fiber as an example of a liquid absorbent fiber into a substantially hourglass shape absorbent core 11 as an example of a predetermined shape. The surface sheet member 13 covering the absorbent core 11 from the skin side of the core 11 and the back sheet member 15 covering the absorbent core 11 from the non-skin side of the core 11 to form an exterior of the absorbent body 10. Further, such an absorbent core 11 may contain, for example, a highly absorbent polymer as a liquid absorbing granular material, or may contain a liquid absorbing material other than liquid absorbing particles and liquid absorbing granular materials. . Further, the absorbent core 11 may be covered with a liquid permeable sheet (not shown) such as tissue paper.

The surface sheet member 13 is, for example, a liquid permeable non-woven fabric having a larger planar size than the absorbent core 11. Further, as shown in FIG. 5B, the inner sheet member 15 is also a sheet having a larger planar size than the absorbent core 11, and an example thereof may be a liquid impervious leakproof such as polyethylene or polypropylene. thin A sheet 15a having a two-layer structure of an outer sheet 15b such as a non-woven fabric. Further, in a state in which the absorbent core 11 is interposed between the inner sheet member 15 and the surface sheet member 13, the leak-proof sheet 15a of the inner sheet member 15 is protruded from the four sides of the absorbent core 11 toward the outside. The surface sheet member 13 is pasted into a frame shape, whereby the absorbent body 10 can be roughly formed.

Further, as shown in FIG. 2, FIG. 3, and FIG. 5B, a so-called three-dimensional folded edge LSG and a leg-surrounded folded edge LG may be formed by the outer sheet 15b. The three-dimensional folded edge LSG is a leakage preventing wall portion LSG which is provided at each end portion of the surface sheet member 13 in the lateral direction. On the other hand, the leg-surrounding folded edge LG is formed in each leg opening of the diaper 1. 1HL, 1HL expansion and contraction unit LG. When the outer sheet 15b is described in detail, first, as shown in Fig. 5B, the lateral dimension of the outer sheet 15b is set larger than the leakage preventing sheet 15a, that is, the outer sheet 15b is prevented. The lateral sides of the drain sheet 15a are largely convex toward the lateral direction. Further, the protruding portion 15bf is folded back toward the center side in the lateral direction at a position where the end portion 10es of the lateral direction of the absorbent body 10 is folded, and the elastic member 17 such as silk rubber is longitudinally located in the vicinity of the folded-back position. It is fixed in the longitudinal direction under elongation, whereby the leg-surrounding edge LG described above is formed. Further, the folded portion 15bg is further extended to the lateral center side, and is joined to the end portion at a position covering the lateral end portion of the surface sheet member 13. Further, the portion joined to the end portion functions as the base end portion LSGb of the three-dimensional hemming edge LSG, that is, a portion on the side of the front end portion which is located laterally closer to the base end portion LSGb as the free end portion LSGf becomes a usable surface. The sheet member 13 stands up. again The front end portion of the free end portion LSGf, the elastic member 18 such as silk rubber is fixed in the longitudinal direction in the longitudinal direction under elongation. Therefore, the absorbent body 10 is bent in the longitudinal direction by the longitudinal contraction of the elastic member 18 so that the side sheet member 13 side becomes the inner peripheral side, but at the time of the bending, the free end portion LSGf is obtained from the elastic member 18 The imparted stretchability contracts in the longitudinal direction and rises from the surface sheet member 13, whereby the free end portion LSGf functions as a three-dimensional folded edge LSG.

Further, although not shown, a liquid permeable sheet such as a thin paper may be interposed between the surface sheet member 13 and the absorbent core 11 or between the back sheet member 15 and the absorbent core 11 as described above. The second sheet.

As shown in FIG. 3, each of the front side belt member 30a and the back side belt member 30b is a sheet member of a substantially rectangular shape in plan view, for example, using a soft sheet such as non-woven fabric as a material. Here, as shown in FIG. 5A and FIG. 5B, each of the belt members 30a and 30b is formed by laminating two pieces of the nonwoven fabrics 31 and 32, and the belt members 30a and 30b are in the central portions 30ac and 30bc of the respective lateral directions. The non-skin side of the absorbent body 10 covers the respective end portions 10ea, 10eb of the absorbent body 10 in the longitudinal direction, and the end portions 10ea, 10eb are joined to the central portions 30ac, 30bc of the belt members 30a, 30b.

Further, the two sheets of non-woven fabrics 31, 32 may not be the same size with each other. For example, in Fig. 6 which is a diagram for the description, a cross-sectional view taken along line VI-VI in Fig. 3 showing such a configuration may be used. That is, in Fig. 6, the longitudinal direction of each other is different, and the non-woven fabric 31 on the non-skin side in the thickness direction is made more longitudinal than the non-woven fabric 32 on the skin side. The end side is convex. Further, in this case, as shown in FIG. 6, in the nonwoven fabric 31 on the non-skin side, the vicinity of the longitudinal end edge of the non-woven fabric 32 on the skin side is formed from the non-woven fabric 32 on the skin side toward the longitudinal projection 31f. The folded-back position is folded back toward the center side in the longitudinal direction. Further, the folded portion 31g is joined by the nonwoven fabric 32 which is superposed on the skin side. Further, at the time of the folding back, a portion of the longitudinal end portions 10ea, 10eb of the absorbent body 10 may be covered from the skin side of the absorbent body 10 by the above-described folded portion 31g.

Here, the overlapping of the absorbent body 10 to the central portions 30ac and 30bc of the above-described belt members 30a and 30b is such that the longitudinal ends 30ae2 and 30be2 of the belt members 30a and 30b do not overlap the absorbent body 10, but The portions 30ac2, 30bc2 of the end portions 30ae2, 30be2 which are located further on the center in the longitudinal direction overlap the absorbent body 10. Further, by this, the longitudinal end portions 30ae2, 30be2 of the belt members 30a, 30b are portions 30ae2, 30be2 which are provided so as not to overlap the absorbent body 10 at all in the transverse direction. Further, since the non-overlapping portions 30ae2 and 30be2 are portions that constitute the waist opening 1HB (Fig. 2) of the diaper 1, the portions 30ae2 and 30be2, and the elastic members 35U to be described later are substantially the entire length in the lateral direction of the portions 30ae2 and 30be2. Continuously set. Further, the longitudinal dimensions La and Lb of the non-overlapping portions 30ae2 and 30be2 of the absorbent body 10 are larger than the front side belt member 30a (Lb>La) in this example. That is, as a whole, the absorbent body 10 is disposed more toward the front side belt member 30a than the back side belt member 30b. Further, according to this, although the smooth absorption of urine is ensured, the slightest portion is limited to these. For example, the above The magnitude relationship of the sizes La and Lb may be reversed (that is, Lb < La), or the above-described sizes La and Lb may be set to 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, 35, such as silk rubber, are interposed between the two non-woven fabrics 31, 32 of the belt members 30a and 30b. Moreover, the nonwoven fabrics 31 and 32 are joined and fixed in the lateral direction by elongation, whereby the belt members 30a and 30b are provided with lateral stretchability. Further, the plurality of elastic members 35, 35, ... are juxtaposed in the longitudinal direction at the side edges spaced apart from each other in the longitudinal direction. Further, the elastic members 35, 35, . . . are respectively provided in both the front side belt member 30a and the back side belt member 30b, and the thickness, the number of the elastic members 35, 35, the longitudinal arrangement position, and the like may be removed. The detailed specifications of the specifications are roughly the same as each other. Therefore, in the following, each of the elastic members 35, 35, ... representing both the front side belt member 30a and the back side belt member 30b, will be described only for the elastic members 35, 35, ... of the front side belt member 30a, and with respect to the back side belt The description of the elastic members 35, 35, ... of the member 30b will be omitted. Further, in Fig. 3, the elastic member 35 of the back side belt member 30b is also denoted by the same reference numeral 35 as the elastic member 35 of the front side belt member 30a. Moreover, this matter is also the same for all the configurations of the back side belt member 30b. For example, the coloring portion 50 and the like of the illustration sheet 40 to be described later are also denoted by the same reference numerals as the illustration sheet 40 and the coloring portion 50 of the front side belt member 30a, and the illustration sheet 40 and the coloring portion 50 of the back side belt member 30b. The description is omitted.

In addition, in the following, the convenience of the description is as shown in FIG. The member 30a is divided into three regions AU, AM, and AD, and the three regions AU, AM, and AD arranged in the longitudinal direction are sequentially referred to as "upper region AU" and "middle region AM" from the longitudinal end side toward the center side. ", and "lower area AD". Further, as can be seen from FIG. 4, any of the regions AU, AM, and AD also becomes a strip-shaped region along the lateral direction.

The upper region AU is a portion constituting the waist opening 1HB of the diaper 1, and this region AU is a region where the lateral full length absorbent body 10 does not overlap at all. Further, in the upper region AU, the elastic member 35U (35) is continuously disposed from the one end portion in the lateral direction of the region AU to substantially the entire length of the other end portion, and is fixed in the lateral direction under the extension. Therefore, the elastic member 35U (35) imparts lateral stretchability to the entire upper end of the upper region AU in the lateral direction, and the stretchability is the stretchability of the waist opening 1HB of the diaper 1.

The central region AM (corresponding to the first region) is a region in which the longitudinal end portion 10ea of the absorbent body 10 is superposed on the lateral center portion AMc and fixed. More specifically, in the central portion AMc of the region AM, the portion 10n in which the absorptive core 11 does not exist in the absorbent body 10 is superposed and fixed. Further, in the central portion AM, the portions AMe, AMe located on both sides of the central portion AMc, the absorbent body 10 are not overlapped.

Here, in the central portion AM, the elastic member 35U (35) is continuously arranged from the one end portion in the lateral direction of the region AM to the substantially entire length of the other end portion, and is fixed in the lateral direction under the extension. Moreover, by virtue of the elastic member 35M (35), the central portion of the AM is substantially extended in the lateral direction. Transverse flexibility. Further, in the portion of the absorbent main body 10 opposed to the central portion AM, the belt member is provided for the purpose of easily viewing the elastic member 35M (35) of the central portion AM from the non-skin side of the diaper 1. The coloring section 50 (Fig. 7) can be described later.

The lower region AD (corresponding to the second region) is a region in which the portion 10p in which the absorptive core 11 exists in the absorbent body 10 is superposed on the central portion ADc in the lateral direction. Further, in the lower region AD, the absorbent bodies 10 are not overlapped in the respective portions ADe, ADe located on both sides of the central portion ADc.

Further, in the portions ADe and ADe, the elastic members 35U (35) are continuously disposed from substantially one end portion of the lateral portion of the portion ADe to the other end portion, and are fixed in the lateral direction under elongation. Further, in this manner, the respective portions ADe and ADe are provided with lateral stretchability in substantially the entire length in the lateral direction.

On the other hand, in the center portion ADc, the elastic member 35D (35) is disposed discontinuously in the lateral direction. More specifically, in this example, the end portions of the elastic member 35D (35) described above are located at the lateral end portions ADce, ADce of the central portion ADc, but in the lateral central portion of the central portion ADc. Since the ADcc elastic member 35D (35) does not exist, the elastic member 35D (35) is discontinuously disposed in the lateral direction in the central portion ADc. Further, when the central portion ADcc elastic member 35D (35) is not present in the central portion ADc, since the stretchability is hardly imparted to the central portion ADcc, the lateral contraction of the central portion ADcc is suppressed. And with this case, since the horizontal of the absorptive core 11 can also be suppressed Since the contraction of the direction is also prevented, the generation of wrinkles of the core 11 is prevented, and the skin side surface of the core 11 is maintained substantially flat. Further, as a result, the liquid absorbing hindrance of the core 11 can be effectively prevented, and leakage of urine due to wrinkles can also be prevented.

In addition, as shown in FIG. 4, the center sheet ADc of the lower region AD is provided with an illustration sheet 40 (corresponding to the second coloring portion) in which an illustration such as an animal (not shown) is formed, but for the same reason as described above. The occurrence of wrinkles in the illustrated sheet 40 can also be suppressed. Therefore, the illustrations are easy to see.

Further, in this example, as shown in Fig. 5B, the belt member 30a is formed by laminating two sheets of non-woven fabrics 31, 32, and the illustrated sheet 40 is interposed in the two sheets of non-woven fabrics 31, 32 which are overlapped. They are fixed to each other by an adhesive or the like, but are not limited thereto. For example, it may be fixed to the non-skin side surface of the belt member 30a without interposing, or may be fixed to the skin side surface of the belt member 30a. Further, when being inserted between the nonwoven fabrics 31 and 32 and being fixed to the skin side surface of the belt member 30a, the illustration of the illustrated sheet 40 is non-woven fabric 31 which can pass through the non-skin side in the belt member 30a. The interfiber gap or the like is visually recognized by the non-woven fabric 31 (32), whereby the non-woven fabric 31 (32) is visible from the non-skin side in the thickness direction. In addition, the material of the illustration sheet 40 may be, for example, a resin film such as a polyethylene film or a polypropylene film, and the illustration may be formed on the soft sheet and on the non-skin side surface. For example, non-woven fabrics and woven fabrics can also be used.

However, as described, the consumption of the elastic member 35D (35) which is discontinuously disposed in the lower region AD (Fig. 4) of the belt member 30a is seen. In addition, the diaper of the diaper 1 is uncomfortable. Further, such an uneasiness may be alleviated if the elastic member 35 that is continuously disposed over substantially the entire length of the belt member 30a in the lateral direction is seen. For example, in this example, the elastic members 35 (35U, 35M) thus continuously disposed are present in the upper region AU and the central region AM. Therefore, if the upper region AU and the elastic members 35U, 35M of the central region AM are viewed, such uneasiness can be eliminated.

However, in many diapers, even in the diaper 1 of the example of FIG. 5A, the outer sheet 15b and the leakage preventing sheet 15a of the inner sheet member 15 which is the non-skin side of the absorbent body 10 are respectively made of white non-woven fabric and A white film is used, and white non-woven fabrics 31, 32 are used for the belt member 30a, and a thin color silk rubber is used for the elastic members 35 (35U, 35M). Therefore, the upper region AU of the belt member 30a of FIG. 4 and the elastic members 35 (35U, 35M) of the middle portion AM are not easily recognized as a protective color, and it is difficult for the consumer to find its existence.

In the present embodiment, the elastic member 35M (35) of the central portion AM (FIG. 4) of the tape member 30a is easily viewed from the non-skin side of the diaper 1, and as shown in FIG. 5A, The member 35M (35) is located on the skin side of the absorbent body 10 in the thickness direction, and the portion corresponding to the central portion AM is colored by a color other than white, whereby the coloring portion 50 is formed corresponding to the central portion AM. Further, by this, the coloring portion 50 can be formed as the background of the elastic member 35M (35) positioned in the central portion AM (for example, refer to FIG. 7), and as a result, the visibility of the elastic member 35M (35) of the central portion AM is improved. . Take Next, a detailed description will be given.

FIG. 7 is a schematic enlarged view of the front side belt 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 colored portion 50 (corresponding to the first colored portion) is provided in the non-skin side of the leakage preventing sheet 15a of the back sheet member 15 provided in the absorbent body 10. A portion opposed to the central region AM (refer to the hatched portion in Fig. 7). Therefore, as shown in Fig. 7, when the elastic member 35M (35) of the central portion AM is viewed from the non-skin side of the diaper 1, the elastic member 35M can be visually overlapped in the colored portion 50 (the hatched portion in Fig. 7). ). Therefore, the elastic member 35M can be viewed from the non-skin side of the diaper 1 by using the colored portion 50 as the background of the elastic member 35M. As a result, it is easy to visually recognize the state in which the elastic member 35M is continuously provided in the lateral direction.

Further, as shown in FIG. 7, the colored portion 50 is formed in a strip shape along the lateral direction. Specifically, the colored portion 50 is formed in a strip shape having a length across the entire length of the leakage preventing sheet 15a (FIG. 5A), and as shown in FIG. 7, the size in the longitudinal direction is set in the central portion AM. Therefore, the visibility of the elastic members 35M, 35M, and 35M which are all in the central region AM (three in FIG. 7) can be improved. Moreover, as is apparent from the above, in the example of FIG. 5A, since the colored portion 50 is continuously provided over the entire length of the leakage preventing sheet 15a in the lateral direction, the elastic member 35M can be surely viewed in the horizontally continuous state. However, the colored portion 50 may be a background of at least one of the elastic members 35M, 35M, which are located in the central portion AM, and therefore the coloring portion 50 may be provided at this time. The planar area AM has a smaller planar size, that is, it can also be accommodated inside the central region AM.

Moreover, in the example of FIG. 5A, the sheet member which is located on the non-skin side in the thickness direction than 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 body 10 and Two of the belt members 30a, and any of the outer sheet 15b and the belt member 30a are made of non-woven fabric. Therefore, the coloring portion 50 of the leakage preventing sheet 15a is formed such that the exterior sheet 15b and the belt member 30a are transparent, and can be viewed at least from the non-skin side of the thin diaper 1, whereby the leakage preventing sheet 15a The coloring portion 50 can function effectively as a background of the elastic member 35M.

Further, in the example of Fig. 7, the illustration sheet 40 is provided in the lower region AD of the belt member 30a, that is, it is not provided in the central portion AM. Therefore, when the illustration sheet 40 is superposed on the colored portion 50 when viewed from the non-skin side of the diaper 1, it can be effectively avoided. As a result, it is possible to effectively prevent the colored portion 50 from being easily seen from the non-skin side.

Further, as described above, the illustration sheet 40 is not provided in the central portion AM, and the coloring portion 50 is provided in the central portion AM, and the description can be switched as follows. In other words, in other words, it can be said that "the colored portion 50 has a portion 50n that does not overlap the illustrated sheet 40 when viewed from the non-skin side of the diaper 1". Further, at this time, also when viewed from the non-skin side, the elastic member 35M of the central portion AM overlaps the portion 50n where the insituation sheet 40 does not overlap in the colored portion 50. Therefore, it is possible to effectively prevent the elastic member 35M which is disposed substantially in the lateral direction from causing wrinkles in the illustrated sheet 40. In the case, it is easier to visually recognize the illustration of the sheet 40.

Moreover, in this example, the outer sheet 15b and the leakage preventing sheet 15a of the inner sheet member 15 of the absorbent main body 10, the elastic members 35 (35U, 35M, 35D), and the belt members 30a (30b) are each colored. In the case of white, the color of the colored portion 50 is set to blue as an example of a color different from white, but it is not limited thereto. For example, it may be set to red or green, and colors other than these may be selected. That is, any color other than white can also be selected. Further, when at least one of the outer sheet 15b, the leakage preventing sheet 15a, the elastic member 35, and the belt member 30a (30b) is a color other than white, the color of the colored portion 50 can be appropriately selected in accordance with the combination of the colors. . That is, when the color of the colored portion 50 can be selected from the non-skin side of the diaper 1 when the elastic member 35M (35) is selected, the elastic member 35M (35) becomes a color in an eye-catching state. For example, the color of the colored portion 50 may be set to a color different from the colors of the elastic member 35M (35) and the leakage preventing sheet 15a, and the color of the colored portion 50 may be set to be the elastic member 35M (35). The color of the three of the leakage preventing sheet 15a and the exterior sheet 15b is different.

Moreover, the definition of the same color as used herein is as follows. First, as a premise, the expression of all the colors can be expressed for each combination of values selected from 0° to 360° for brightness, hue, and chroma. Moreover, under this premise, for each of the two colors of the same color, the values of the brightness, the hue, and the chroma are compared, and when the comparison results, that is, the brightness, the hue, and the chroma are respectively When the values enter the range of ±5° of the color value of each other, they are regarded as the same Color, and even if one of the values of lightness, hue, and chroma does not enter the range of ±5°, it is regarded as "different colors."

Further, in the example of FIG. 5A and FIG. 7, the non-skin side surface of the leakage preventing sheet 15a is directly colored to form the coloring portion 50, but is not limited thereto. For example, the colored portion 50 may be provided by bonding the other sheet to be colored to the leakage preventing sheet 15a. Further, instead of the leakage preventing sheet 15a, the colored portion 50 may be formed on the exterior sheet 15b. Further, as for the method of molding the coloring portion 50 at this time, the same method as in the case of the leakage preventing sheet 15a can be used. In other words, the non-skin side surface of the exterior sheet 15b may be directly colored to form the colored portion 50, or the colored sheet 50 may be formed by joining the colored sheet to the exterior sheet 15b.

However, as is apparent from the foregoing, the colored portion 50 is a portion provided in the absorptive body 10 and opposed to the central portion AM. That is, as shown in Fig. 7, the portion 10n in which the absorptive core 11 does not exist in the absorbent body 10 is provided. On the other hand, the elastic member 35M (35) which is required to be horizontally continuous in the colored portion 50 is also provided in the central portion AM. Further, such an elastic member 35M (35) allows the absorbent body 10 to contract in the lateral direction. However, the central portion AM of the elastic member 35M (35) is provided, as is known from the above, the absorbent body 10 is known. A portion 10n in which the intermediate absorbent core 11 is not present. Therefore, the occurrence of wrinkles in the absorbent core 11 due to the elastic member 35M (35) can be effectively suppressed, and the skin side surface of the absorbent core 11 can be easily maintained substantially flat. Moreover, this case also contributes to the prevention of the liquid absorbing hindrance of the absorbent core 11.

The embodiments of the present invention have been described above, but the above-described embodiments are intended to facilitate the understanding of the present invention and are not intended to limit the present invention. It is to be understood that the invention may be modified or modified without departing from the spirit and scope of the invention. For example, there may be variations such as those shown below.

In the above-described embodiment, the coloring portion 50 as an example of the first colored portion is provided in the portion of the absorbent body 10 that faces the central portion AM of the abdominal band member 30a, but is not limited thereto. . That is, the same coloring portion 50 may be provided in a portion of the absorbent body 10 of FIG. 4 opposite to the central portion AM of the back side belt member 30b. Further, if so provided, the consumer can surely recognize the elastic member 35M (35) positioned in the central portion AM of the back side belt member 30b, that is, the elastic member 35M which is continuously disposed substantially in the lateral direction of the central portion AM. (35) By this, it is possible to alleviate the anxiety of the consumer that the diaper 1 is not slipped downward.

In the above-described embodiment, the purpose of reducing the stretchability of the central portion ADc of the lower portion AD of the illustrated sheet 40 in the belt member 30a (30b) is reduced, and the elastic member 35D (35) of the central portion ADc is set to be no. continuous. Further, as an example of the discontinuous elastic member 35D, as shown in Fig. 7, the lateral end portions ADce and ADce of the central portion ADc have the elastic member 35M (35) present, but in the center The lateral central portion ADcc in the portion ADc exemplifies a configuration in which the elastic member 35D (35) does not exist, but is not limited thereto.

In other words, if it is necessary to reduce the stretchability of the central portion ADc of the lower region AD, and the elastic member 35D is discontinuously disposed in the central portion ADc, the elastic member 35D may exist in the central portion ADc and be located at the central portion ADcc. . Fig. 8 is a schematic plan view showing an example of the same. In addition, FIG. 8 shows a state in which the nonwoven fabric 31 on the non-skin side in the belt member 30a is removed, and the elastic members 35 (35U, 35M, 35D) are exposed to the outside. In the example of Fig. 8, the elastic member 35D located in the central portion ADcc is in a state of being finely cut. Further, when such a thin strip state is formed, the elastic member 35D does not substantially impart stretchability to the central portion ADcc. Therefore, if it is the elastic member 35D in a thin strip state, it may exist in the center part ADcc. The length of the elastic member 35D in the thin strip state is, for example, set to a length of 5 mm or more larger than 0 mm, and more desirably set to a length of 3 mm or less larger than 0 mm. However, when the finely-cut elastic member 35D is present, it is desirable that the elastic portion 35D does not exist in the central portion (Fig. 7) because the appearance is deteriorated.

In the above-described embodiment, the elastic member 35D (35) is discontinuously disposed in the lateral center portion ADc of the lower region AD of FIG. 4, but is not limited thereto. For example, the elastic member 35D (35) may not be disposed in the central portion ADc. That is, in the example of Fig. 4 described above, the end portion of the central portion ADc elastic member 35D (35) comes to the position of each of the lateral end portions ADce, ADce, but the end portion of the elastic member 35D (35) does not have Come to the position of the ADce at the end of the central ADc.

In the above embodiment, the strip-shaped coloring portion along the lateral direction is used. The anti-leakage sheet 15a is provided as an example of the first colored portion 50, and the shape of the coloring portion 50 is not limited thereto. For example, a horizontal line shape in which a plurality of straight portions in the lateral direction are arranged in the longitudinal direction may be arranged, or a vertical line shape in which a plurality of straight portions along the longitudinal direction are arranged in the lateral direction may be arranged, and the longitudinal direction and the lateral direction may be applied. A plurality of straight portions in the direction of each other are arranged in a diagonal shape. Furthermore, it may be other than the geometric appearance of such a type, for example, characters, drawings, symbols, and the like. Moreover, the coloring method of the leakage preventing sheet 15a for forming the coloring portion 50 is a printing method such as flexographic printing, inkjet printing, or screen printing.

In the above-described embodiment, the material of the exterior sheet 15b and the belt members 30a and 30b is not woven, and it is not limited to the nonwoven fabric. In other words, the coloring portion 50 of the leakage preventing sheet 15a can be used without any problems other than the woven fabric, as long as it can be viewed from the non-skin side of the diaper 1 by the form of the outer sheet 15b and the belt members 30a and 30b. For example, it may be a woven fabric or a sheet member other than the woven fabric. In other words, the exterior sheet 15b may be omitted. In this case, the leakage preventing sheet 15a is an exterior of the absorbent body 10.

In the above-described embodiment, an illustration (not shown) of an animal or the like is formed on the illustrated sheet 40, and it is not limited to an illustration of an animal or the like. For example, it may be a picture other than an animal, or may be a character, a symbol, or a pattern. In other words, the illustration sheet 40 may be formed as long as the design pattern of the diaper 1 can be improved. Further, the formation of the pattern of the illustrated sheet 40 may be performed by the above-described printing method.

In the above embodiment, the silk rubber is exemplified as the elastic member 35. (35U, 35M, 35D), but this is not limited to this. For example, a strip-shaped rubber may be used as the elastic member 35, or a stretchable strip-shaped nonwoven fabric or a stretchable strip-shaped resin film may be used.
