In the disposable diaper described in Patent Document 1 above, the leg flap absorbers located on the left and right sides of the central absorbent body are continuously connected in the low-rigidity region, so the diaper inseam in which the leg flap absorbent body is disposed The mobility of the side part in the part was not sufficient. Moreover, in the disposable diaper described in Patent Document 4, since the upper-layer absorbent web body is arranged and fixed so as to overlap with the peripheral portion of the lower-layer absorbent web body, the side part of the diaper crotch is movable. Sex was not enough. In this way, if the lateral mobility is not sufficient, sufficient followability cannot be obtained, so the adhesion around the thigh root of the wearer, particularly the adhesion between the absorbent body and the wearer's skin is insufficient. There was a possibility of causing side leakage. Further, the disposable diaper described in Patent Document 4 has a narrow width at the crotch portion and is not configured to have an absorber around the legs. Furthermore, even if gathers are installed on the side of the absorber, the rise of the side portion is lowered due to the rigidity of the lower layer absorber, and the holdability of the urine absorbing pad is hindered.
Furthermore, in the disposable absorbent article described in Patent Document 2, since the hole portion is provided in the center portion in the width direction along the longitudinal direction at the leg periphery portion, the liquid absorption performance in the center portion has been lowered.
Furthermore, in the disposable diaper described in Patent Document 3, at least both side portions of the central portion in the longitudinal direction of the central absorbent body are provided with a separation portion, and this separation portion is opened to both side portions of the other portion in the longitudinal direction. Therefore, there is a possibility that the liquid leaks from the open part.

  The present invention has been made in view of the above points, and provides an absorbent article that improves the fit of the thigh base or the crotch and prevents leakage from the thigh base. Is an issue.

  The present invention comprises a top sheet, a back sheet, and an absorbent body sandwiched between both sheets, and the absorbent body is located at the center of the crotch at the center of the article width direction, on both sides of the central absorbent body. A pair of side absorbers arranged, a separation portion between the central portion absorber and the side absorber, and one of the absorbers at both ends of the pair of separation portions in the longitudinal direction of the article. An absorbent article is provided in which an intermediate sheet is interposed between the central absorbent body and the side absorbent body.

  The absorbent article of the present invention has an excellent effect that it can improve the fit of the thigh base or the crotch, and can reliably prevent leakage from the thigh base.

A preferred embodiment of an absorbent article according to the present invention will be described with reference to the drawings. First, an outline of the disposable diaper 10 of the present embodiment will be described with reference to FIG. In addition, in FIG. 1, the expandable disposable diaper for adults was shown.
As shown in FIG. 1, the disposable diaper 10 of the present embodiment includes a liquid-permeable surface sheet 1 disposed on the skin contact surface side, and a moisture-permeable and liquid-impermeable surface disposed on the non-skin contact surface side. Back sheet 2 and an absorbent body 3 that is sandwiched between both sheets and absorbs and holds liquid.
The top sheet 1 and the back sheet 2 have a vertically long shape. The absorbent body 3 has a slightly shorter length in the longitudinal direction (Y direction) and the width direction (X direction) than these, and a central part absorbent body 3c located at the center of the article width direction at the crotch, the central part absorbent body It has a pair of side part absorber 3a, 3b distribute | arranged to the both sides of 3c. The absorbent body 3 is disposed substantially in the center with its longitudinal direction coinciding with the longitudinal direction of the top sheet 1 and the back sheet 2. These topsheet 1, backsheet 2 and absorber 3 are joined together by a hot melt adhesive or the like, for example.

A space 4 (4a, 4b) is provided between each of the side absorbers 3a, 3b and the central absorber 3c. Part of the absorbent body 3 exists at both ends of the pair of spaced-apart portions 4a and 4b in the longitudinal direction (Y direction) of the article. Therefore, the separation portion 4 does not reach both end portions in the longitudinal direction of the article.
An intermediate sheet 5 is interposed between the side absorbent bodies 3a and 3b and the central absorbent body 3c. Accordingly, the side absorbent bodies 3 a and 3 b and the central absorbent body 3 c are separated by the intermediate sheet 5. In the article width direction (X direction) near the center of the article in the longitudinal direction, the side absorbent bodies 3a, 3b and the central absorbent body 3c are in contact with or separated from each other in a plan view. When viewed three-dimensionally, since the intermediate sheet 5 is interposed between the side absorbers 3a and 3b and the central absorber 3c, the side absorbers 3a and 3b and the central absorber 3c are at least The thickness of the intermediate sheet 5 is separated.
As described above, when viewed three-dimensionally, the side absorbers 3a and 3b and the central absorber 3c are separated from each other, and the side absorbers 3a and 3b and the central absorber 3c are viewed in a plan view. Since the side absorbers 3a and 3b are easily deformed because they are in contact with or separated from each other, there is an effect that the fit is excellent around the thigh root and the crotch.

  The length Ls in the Y direction of the side absorbers 3a and 3b is defined as the length of the portion having the opening 33 that penetrates the side portions 3a and 3b including the separation portion 4, and the length in the Y direction of the central absorber 3c. Lc is defined as the length of the part having the separation part 4 on the side part. Therefore, the length Lc is equal to the length Ld of the separation portion 4.

The distance D (Da, Db) between the side absorbers 3a, 3b and the central absorber 3c in plan view is 0 mm (contact in a plan view) or more, preferably 3 mm or more, more preferably 5 mm. That is 40 mm or less, preferably 30 mm or less, and more preferably 25 mm or less. Then, it is 0 mm (contact in a plan view) or more and 40 mm or less, preferably 3 mm or more and 30 mm or less, more preferably 5 mm or more and 25 mm or less. Therefore, the side absorbers 3a and 3b and the central absorber 3c do not overlap in plan view. Moreover, the effect of this invention mentioned later cannot be show | played in the state which the side part absorbers 3a and 3b and the center part absorber 3c have overlapped in planar view. On the other hand, when the separation distance D is too long, it is not preferable from the viewpoint that the widths of the side absorbent bodies 3a and 3b are narrowed and crotch leakage is likely to occur.
Further, the length Ld in the article longitudinal direction (Y direction) of the separation portion 4 is 100 mm or more, preferably 140 mm or more, more preferably 180 mm or more, 400 mm or less, preferably 380 mm or less, and more preferably 360 mm or less. And they are 100 mm or more and 400 mm or less, Preferably they are 140 mm or more and 380 mm or less, More preferably, they are 180 mm or more and 360 mm or less. When the length Ld of the separation portion 4 is too long, the excreted urine flows out in the front-rear direction of the separation portion 4 and is likely to leak before and back, which is not preferable from the viewpoint of preventing leakage, and is too short Therefore, it is not preferable from the viewpoint that the fit property is lowered.

The width Ws (width in the X direction) of the side absorbers 3a and 3b is 30 mm or more, preferably 40 mm or more, more preferably 50 mm or more, 140 mm or less, preferably 120 mm or less, more preferably 100 mm or less. . And they are 30 mm or more and 140 mm or less, Preferably they are 40 mm or more and 120 mm or less, More preferably, they are 50 mm or more and 100 mm or less. When the width Ws of the side absorbent bodies 3a and 3b is too long, it is not preferable from the viewpoint of reducing fit and followability, and when it is too short, it is not preferable from the viewpoint of preventing crotch leakage.
Further, the length Ls (the length in the Y direction) of the side absorbers 3a and 3b is not less than the length Ld of the spacing portion 4, and is not less than 200 mm, preferably not less than 240 mm, more preferably not less than 280 mm, It is 600 mm or less, preferably 570 mm or less, more preferably 540 mm or less. And it is 200 mm or more and 600 mm or less, Preferably it is 240 mm or more and 570 mm or less, More preferably, it is 280 mm or more and 540 mm or less. When the length Ls of the side absorbent bodies 3a and 3b is too long, the overlap between the first absorbent body and the second absorbent body is shortened on the end side in the longitudinal direction of the article. It is not preferable from the viewpoint of causing leakage and the fit of the waistline is likely to be lowered, and if it is too short, it is not preferred from the viewpoint of the fit and followability of the crotch without the thigh root.

The central absorbent body 3c has a width Wc (width in the X direction) of 60 mm or more, preferably 75 mm or more, more preferably 90 mm or more, 200 mm or less, preferably 180 mm or less, more preferably 160 mm or less. And they are 60 mm or more and 200 mm or less, Preferably they are 75 mm or more and 180 mm or less, More preferably, they are 90 mm or more and 160 mm or less. In the case where the width Wc of the central absorbent body 3c is too long, the spaced-apart portion 4 in a plan view is lost, and the side absorbent bodies 3b and 3c overlap with the side absorbent bodies 3b and 3c. Is not preferable from the viewpoint that the width of the separation portion 4 becomes too wide and easily leaks crotch and back.
Further, the length Lc (the length in the Y direction) of the central absorbent body 3c is equal to the length Ld of the separation portion 4, and is 150 mm or more, preferably 180 mm or more, more preferably 200 mm or more, preferably Is 400 mm or less, more preferably 360 mm or less. And they are 150 mm or more and 400 mm or less, Preferably they are 180 mm or more and 400 mm or less, More preferably, they are 200 mm or more and 360 mm or less. When the length Lc of the central absorbent body 3c is too long, the overlap between the first absorbent body and the second absorbent body is shortened on the end side in the longitudinal direction of the article, and the pre-leakage and back-leakage are caused by a decrease in absorption performance. It is not preferable from the viewpoint of causing, and if it is too short, it is not preferable from the viewpoint of decreasing flexibility. The separation part 4 is arranged at least in the crotch part C, and may be arranged so as to protrude in the direction of the back side part R and the abdominal side part F.

The side absorbers 3 a and 3 b are constituted by the first absorber 31, and the central absorber 3 c is constituted by the second absorber 32. That is, the side absorbers 3 a and 3 b are included in the first absorber 31, and the central absorber 3 c is included in the second absorber 32. The first absorber 31 is arranged in an upper layer than the second absorber 32 through the intermediate sheet 5.
The first absorbent body 31 has, for example, an outer edge whose shape is curved inward at the crotch part, and spreads outward at the site of the abdominal side F or the back side R, and passes through the central part thereof. 33. The first absorber 31 on the side in the width direction of the opening 33 serves as the side absorbers 3a and 3b.
As for the 2nd absorber 32, the longitudinal direction both end part side is longer than the width | variety of the said opening part 33, and the longitudinal direction center part is shorter than the width | variety of the said opening part 33. FIG. For example, the second absorber 32 may have a shape curved inward at the crotch part. Thereby, a gap in plan view is formed between the first absorbent body 31 and the second absorbent body 32, and the gaps serve as the separation portions 4a and 4b. Accordingly, the length of the separation portion 4 is equal to or less than the length of the opening portion 33 in the longitudinal direction. Usually, since the second absorbent body 32 is disposed so as to overlap the first absorbent body 31 at the side of the opening 33 on the longitudinal end side, the longitudinal length Lc of the central absorbent body 3c is the above-described length Lc. As described above, the distance Ld is equal to the length Ld of the separation portion 4. In addition, the first absorber 31 and the second absorber 32 overlap each other at both ends in the longitudinal direction of the opening 33.

The said 1st absorber 31 and the 2nd absorber 32 can take various shapes.
For example, as shown in FIG. 2A, the first absorbent body 31 has a so-called hourglass shape with a narrowed central part, and has a rectangular opening 33. The second absorbent body 32 has a so-called hourglass shape constricted at the center in the longitudinal direction, and the first absorbent body 31 and the second absorbent body 32 overlap each other at both ends of the longitudinal opening 33. In addition, the width of the second absorber 32 is narrower than the width of the opening 33 in plan view at the central portion in the longitudinal direction. Further, as shown in FIG. 2 (b), the shape of the first absorber 31 in the configuration shown in FIG. Further, as shown in FIG. 2C, in the configuration shown in FIG. 2A, the first absorbent body 31 and the second absorbent body 32 may be rectangular. In this case, since the width of the second absorbent body 32 is narrower over the entire length direction than the width of the opening 33, the length Ls of the side absorbent bodies 3a and 3b in the longitudinal direction and the length of the central absorbent body 3c. Lc is equal to the length Ld of the separation portion 4.

Next, the first absorber 31 will be described in detail with reference to FIG.
The first absorber 31 has an opening (a hollow portion) 33 that passes therethrough. The width Wh in the article width direction (X direction) of the opening 33 is preferably wider than the width in the X direction of the second absorbent body 32. For example, the width Wh of the opening 33 in the crotch part is the width of the second absorbent body 32. The width Wc at the crotch is at least 0 mm or more, preferably 6 mm or more, more preferably 10 mm or more, and the difference between the width Wh and the width Wc is 80 mm or less, preferably 60 mm or less, more preferably 50 mm or less. And it is 0 mm to 80 mm wide, preferably 6 mm to 60 mm wide, more preferably 10 mm to 50 mm wide. In the case of 0 mm, the side portion of the second absorbent body 32 arranged in the longitudinal direction (Y direction) of the second absorbent body 32 is in contact with the side portion of the opening 33 arranged in the longitudinal direction of the article. . In three dimensions, since the intermediate sheet 5 is arranged between the first absorbent body 31 and the second absorbent body 32 in the crotch part, the first absorbent body 31 and the second absorbent body 32 are It is separated.
Therefore, the width of one of the spacing portions 4 on both sides is ½ of the value of Wh−Wc, and is as described above.
