JP-A-8-322878

  In the diaper disclosed in Patent Document 1, even if the movable portion of the leak-proof sheet functions as a barrier that prevents the stool from flowing in the lateral direction, the movable portion does not cover the excreted stool from above. Therefore, the stool excreted in the diaper is exposed from between the leak-proof sheets, and the stool easily comes into contact with the wearer's crotch and buttocks. When excreted stool contacts the wearer's crotch or buttocks, the stool may adhere to the crotch or buttocks, and the wearer's skin may be contaminated extensively by stool that should be held in the diaper.

  An object of the present invention is to provide a disposable wearing article in which excreted stool does not adhere to the wearer's crotch or buttocks, and the skin of the wearer's skin due to stool can be prevented.

  The premise of the present invention to solve the above problems is that the skin contact surface and the non-skin contact surface are provided, and the liquid-permeable surface sheet is located on the skin contact surface side, while the non-skin contact surface A liquid-impervious back sheet is located on the side of the front surface, the front waistline region and the back waistline region, the crotch region located between the waistline regions, both ends extending in the lateral direction, and both sides extending in the vertical direction Each of the liquid-resistant leak-proof sheets extending in the longitudinal direction of the both side portions of the skin contact surface of at least the crotch region of the front and rear waist regions and the crotch region, Each of the leak-proof sheets has a fixed portion that is located on both sides and extends in the vertical direction, and a stretchable movable portion that extends in the vertical direction in parallel with the fixed portion and has an upright orientation above the skin contact surface. And fixed front and rear end portions located on both sides in the longitudinal direction of the movable portion and lying in the lateral direction. It is a disposable wearing article.

  The feature of the present invention based on the premise is that the lateral separation dimension between the vertices of the movable part gradually increases from the fixed rear end part side toward the fixed front end part side. The skin contact surface exposed from the end extends from the fixed rear end portion side toward the fixed front end portion side and spreads toward the end, and is attached to the hydrophobic nonwoven fabric and the fiber nonwoven fabric so as to extend in the lateral direction. And a stretchable end sheet that is disposed between the movable parts in the rear waist region and draws the movable parts in the lateral direction, and the stretchable end sheet. Has a fixed both ends joined to the movable part between the liquid-permeable surface sheet and the leak-proof sheet, and a free intermediate part extending between the fixed both ends.

  In an example of the embodiment of the present invention, a tape fastener that is a male mechanical fastener is provided on each of the both side portions of the rear waist area, while the non-skin contact surface of the front waist area is A female mechanical fastener with which a male mechanical fastener is engaged, provided with a target tape extending in the lateral direction, and by fixing the tape fastener to the target tape, the front waistline region and the rear waistline And the target tape and the apex of the movable part of the leak-proof sheet are overlapped in the thickness direction of these sheets via the back sheet and the top sheet, and the elastic end sheet The lateral length dimension is narrower than the lateral length dimension of the target tape.

  According to the disposable wearing article according to the present invention, a stool storage space for storing stool is formed between the skin contact surface and the movable part extending toward the fixed rear end of the leakproof sheet, and excreted during wearing of the article. The passed stool passes between the vertices of the movable part and is stored in the stool accommodation space, and the movable part extending toward the fixed rear end of the leakproof sheet covers the stool from above. In the article, the stool is difficult to be exposed between the leak-proof sheets, the stool can be prevented from adhering to the crotch part and the buttock of the wearer, and the skin of the wearer's skin due to the stool can be prevented. In this article, the lateral distance between the apexes of the movable part gradually increases from the fixed rear end side toward the fixed front end part, and the skin contact surface exposed from between the leakproof sheets is fixed. Since the urine extends from the end side toward the fixed front end side, the urine is not excreted outside the movable part, and the lateral flow of the excreted urine moves the leakproof sheet. This prevents the urine leakage from both sides.

FIG. 8 is a view of the crotch portion of the wearer as viewed from below, and FIG. 9 is a view of the wearer as viewed from the side of the buttocks. An example of the procedure for wearing the article 20A is as follows. The wearer's buttocks are placed on the skin contact surface 27 of the crotch region 22, the crotch region 22 is bent, and the front waistline region 21 is placed on the wearer's abdomen. Next, the both side portions 26 of the rear waist region 23 are overlapped on the outside of the both side portions 26 of the front waist region 21 so that the both side portions 26 of the rear waist region 23 are positioned on the wearer's abdomen. The free end 62 of the tape fastener 60 is fixed to the target tape 64 and the front waistline region 21 and the back waistline region 23 are connected. The article 20A to which the front and rear waist areas 21 and 23 are connected is formed with a waist opening and a pair of leg openings (not shown).

  In the article 20 </ b> A, the apex 43 of the movable portion 40 of the leak-proof sheet 34 extending to the crotch region 22 approaches or abuts the root of the wearer's crotch region, and the movable portion 40 extends from the crotch region 22 to the rear waist region 23. The apex 43 enters a crack in the wearer's buttocks and approaches or contacts both sides of the anus. In the article 20A, the stool excreted during wearing is stored in the stool storage space 46 through the apex 43 of the movable part 40 and in the pocket 53, and the movable part 40 and the end seat 45 are disposed above the stool. Cover from. The urine excreted between the vertices 43 of the movable part 40 passes through the top sheet 29 and is absorbed and held by the core 31.

  In the article 20 </ b> A, the distance between the vertices 43 of the movable portion 40 gradually decreases from the crotch region 22 toward the rear waist region 23, and the stool accommodation space is provided between the topsheet 29 and the movable portion 40 of the leak-proof sheet 34. 46 and the pocket 53 is formed between the top sheet 29 and the end sheet 45, the excreted stool is stored in the space 46 and the pocket 53, and the crotch region 22 and the rear waist region. The stool from which the movable part 40 and the end part sheet | seat 45 of the leak-proof sheet | seat 34 extended to 23 were excreted is covered reliably from the upper direction. In the article 20A, the excreted stool is difficult to be exposed from between the movable parts 40, the stool does not contact the wearer's crotch or buttock, and the stool can be prevented from adhering to the crotch or buttock. Can prevent the wearer's skin from being soiled. In the article 20A, the flow of urine and stool in the lateral direction is blocked by the movable portion 40 of the leak-proof sheet 34, and leakage of urine and stool from the side portions 26 can be prevented. The end seat 45 prevents the stool from leaking from the rear waist area 23.

  Since the end sheet 45 having the part 52 that can be expanded and contracted in the lateral direction is attached to the movable part 40 of the leak-proof sheet 34 so that the article 20A can be contracted, the article 20A is fixed by the operation of the wearer while wearing the article 20A.
