In the following description, with the diaper 100 worn by the wearer as a reference, the wearer's abdomen side is the front side and the back side is the back side, and the direction perpendicular to the front-rear direction in the horizontal plane is the left-right direction ( Or, it is defined as the width direction).

  As shown in FIGS. 1 and 2, the diaper 100 includes a crotch part 1 applied to the wearer's crotch part, a ventral part 2 extending to the front side of the crotch part 1 and applied to the wearer's abdomen. The back portion 3 extends to the rear side of the crotch portion 1 and is applied to the back portion of the wearer. Fastening tapes 4 for fastening to the abdominal side 2 are provided at both ends of the back side 3.

  As shown in FIG. 1, the diaper 100 is attached to the lower half of the wearer in the unfolded state, and is fastened to an exterior portion (specifically, an outer layer sheet 51 described later) of the abdominal side 2. By fastening the fastening tape 4 to the part 21, it is comprised as a disposable paper diaper which connects the abdomen side part 2 and the back side part 3 cyclically | annularly, and forms a pants type.

  As shown in FIG. 2, the crotch portion 1 is formed such that both side portions are curved inward so as to gradually become thinner toward the center. The curved portion forms an opening around the leg by connecting the back side portion 3 and the ventral side portion 2 with the fastening tape 4.

  As shown in FIG. 3, the exterior portion of the diaper 100 is composed of an outer layer sheet 51 and an inner layer sheet 52. The outer layer sheet 51 and the inner layer sheet 52 are joined in a state where they are overlapped with each other by a hot melt adhesive or the like. In addition, although illustration is abbreviate | omitted, the edge part of the outer layer sheet | seat 51 is return | folded by the edge part upper surface side of the inner layer sheet | seat 52, and is joined in the overlapped state. By the laminated structure of the outer layer sheet 51 and the inner layer sheet 52, the exterior portions of the crotch portion 1, the abdominal side portion 2, and the back side portion 3 are configured.

  In the portion corresponding to the waist circumference of the wearer side portion 2 and the back side portion 3, an elastic member 53 for forming a waist gather is extended from the natural length along the left-right direction. It is attached. Due to the expansion and contraction action of the elastic member 53, this portion is in close contact with the wearer's waist.

  Further, an elastic member 54 for forming leg gathers is provided between the outer layer sheet 51 and the inner layer sheet 52 in a state where the elastic members 54 for forming leg gathers are extended in the respective curved portions of the crotch portion 1 corresponding to the leg circumference. Is attached. Due to the expansion / contraction action of the elastic member 54, the opening around the leg of the diaper 100 comes into close contact with the periphery of the leg.

  The outer layer sheet 51 and the inner layer sheet 52 are made of water-repellent waterproof sheets, and specifically, are formed of a water-repellent nonwoven fabric such as a bond nonwoven fabric. Therefore, the part which comprises the inner side of the exterior body of the crotch part 1, the abdominal side part 2, and the back side part 3 will be comprised with the waterproof sheet. The elastic members 53 and 54 are made of an elastic stretchable material (polyurethane yarn, polyurethane film, natural rubber, etc.) used for ordinary paper diapers. In the stretched state, a hot melt adhesive, heat welding, ultrasonic welding or the like is used. It is stuck on each part by the attaching means. And the absorption part 6 for absorbing body fluids, such as urine, is installed in the surface of the inner layer sheet | seat 52. FIG.

  As shown in FIG. 3, the absorbent section 6 includes an absorbent body 61 having liquid retention as an absorbent body main body, a top sheet 62 covering the skin surface side (upper side in FIG. 3) of the absorbent body 61, absorption The back sheet 63 is provided so as to wrap around the outer surface side (the lower side in FIG. 3) opposite to the skin surface side of the body 61, and has a structure formed in a rectangular shape extending in the front-rear direction.

  The absorber 61 has, for example, a structure in which a polymer absorber (SAP: Superabsorbent Polymer) in which sodium polyacrylate is granulated is covered with a liquid-permeable auxiliary sheet. Excreted bodily fluids such as urine, spillage and menstrual blood penetrate the top sheet 62 and reach the absorber 61, and are then adsorbed by the polymer absorber.

  The absorbent body 61 is a mass of hydrophilic fibers such as pulverized pulp fibers and cellulose fibers, and a mass obtained by mixing a polymer absorbent is pasted on a paper sheet such as tissue paper or a liquid-permeable nonwoven fabric sheet. You may be comprised by the thing. However, in order to suppress the bulk of the absorbent body 61, it is desirable that the absorbent body 61 is composed of a polymer absorbent body without pulp.

  The top sheet 62 is made of, for example, a non-woven fabric that is made liquid permeable by treating the surface of hydrophobic fibers (polypropylene, polyethylene, polyester, polyamide, nylon, etc.) with a surfactant. However, the top sheet 62 may be made of a nonwoven fabric using hydrophilic fibers (cellulose, rayon, cotton, etc.).

  Moreover, the back sheet 63 is comprised with the plastic film which stuck the plastic film and the highly flexible nonwoven fabric, for example. However, the back sheet 63 may be made of a water-repellent nonwoven fabric using hydrophobic fibers (polypropylene, polyethylene, polyester, polyamide, nylon, etc.).

  Furthermore, the side sheets 64 and 64 are joined to the width direction both sides by the side of the skin surface in the absorption part 6 with the hot-melt-adhesive etc., respectively along the front-back direction. Moreover, the elastic member 65 for forming a three-dimensional gather is attached to the inner edge part of each of the side sheets 64 and 64 in the state extended | stretched rather than the natural length along the front-back direction. Due to the expansion and contraction action of the elastic member 65, a three-dimensional gather 7 is formed that rises inward to be pressed against the wearer's skin.

  For the side sheet 64, for example, a plastic film, a plastic film on which a highly flexible nonwoven fabric is pasted, or a hydrophobic fiber (polypropylene, polyethylene, polyester, polyamide, nylon, etc.) is used as in the case of the back sheet 63 and the like. It is composed of a water-repellent nonwoven fabric. The elastic member 65 is made of the same material as the elastic members 53 and 54.

  Further, both end portions in the front-rear direction (longitudinal direction) of the absorbent portion 6 are covered with end press sheets 66, 66 joined to the abdominal side portion 2 or the back side portion 3 with a hot melt adhesive or the like. Thereby, it is suppressing that the edge part of the absorption part 6 contacts skin directly.

  As shown in FIG. 2, a part of the outer side surface of the side sheet 64 that forms the pair of three-dimensional gathers 7, 7 is distinguished from other neighboring parts (hereinafter referred to as “proximity parts”). The identification unit 8 is provided. Here, the inner layer sheet 52, the absorbing portion 6, other portions on the side sheet 64, and the like correspond to this proximity portion. Since the identification unit 8 is provided on the outer side surface of the side sheet 64, the wearer or the like can easily recognize the identification unit 8 when the diaper 100 in the unfolded state illustrated in FIG.

  Specifically, the identification unit 8 is configured so as to be visually identifiable from the adjacent site by forming it so as to exhibit a color different from the color of the adjacent site by printing or coloring. Here, the color of the identification unit 8 may be determined according to the color of the adjacent portion. For example, when the color is a clear color such as pink or green, it is considered that the visibility is excellent. However, it may be colored with other colors. Furthermore, the identification part 8 is not restricted to what is comprised with a single color, and may be colored with the several color which combined the other kind of color.

  Further, a light emitter such as a phosphorescent paint (for example, alumina-based oxide) may be applied to the identification unit 8. In this case, since the position of the three-dimensional gather 7 can be identified by the identification unit 8 even in a dark environment, the visibility of the identification unit 8 can be improved. In addition, the identification unit 8 is not limited to an aspect configured to exhibit a specific color, and is configured to be visually identifiable, for example, so as to exhibit a pattern different from the adjacent portion. It may be. Further, the recognition unit 8 may be configured to present a figure having some meaning (for example, including an arrow pointing to the three-dimensional gather 7, a character such as “Draw”, and other symbols).

  Next, the position where the identification unit 8 is provided will be described. When the diaper 100 is mounted in a state where the top of the standing three-dimensional gathers 7 is in contact with the buttocks, male or female genitals are stored in a space sandwiched between the pair of three-dimensional gathers 7. At this time, since the three-dimensional gather 7 is flexibly adhered between the crotch by the elastic member 65 provided in the three-dimensional gather 7, it is suppressed that body fluids such as urine discharged from the genitals leak outside the three-dimensional gather 7. The

  Therefore, in the present embodiment, as shown in FIG. 2, a side seat provided from the crotch portion 1 to the ventral side portion 2 so that the wearer can correctly wear the diaper 100 by placing the three-dimensional gather 7 on the buttocks. Among 64, the identification part 8 is provided at a position corresponding to the buttocks (specifically, a position slightly deviated from the central position of the crotch part 1 to the ventral part 2). The wearer confirms the identification part 8 with his / her eyes, holds the part with his / her finger, erects the three-dimensional gather 7, and puts the diaper 100 on the buttocks as it is, thereby wearing the three-dimensional gather 7 correctly. be able to. Thus, the identification part 8 can function as a mark at the time of wearing for the wearer or the like.

  Of course, it is not hindered to provide the identification portion 8 other than the portion corresponding to the collar portion. However, the wearer or the like is provided so as to be unevenly distributed on the front side (the abdomen side 2 side) of the side seats 64 in order for the wearer or the like to be a mark for the wearer or the like to correctly apply the three-dimensional gather 7 to the buttocks. It is preferable.

  In addition, when the side sheet 64 is made of a relatively thick thin material, if a part of the side sheet 64 is colored by printing or coloring, the identification unit 8 may be difficult to be visually recognized because the hue is thin. In such a case, you may provide an identification part in parts other than on the side seat | sheet 64. FIG.

  FIG. 4 is a top view showing the diaper 100 in which the identification portion 8A is provided on the inner layer sheet 52 in an expanded manner. As shown in FIG. 4, an identification portion 8 </ b> A is provided in the inner layer sheet 52 at a position outside the side sheet 64 and close to the identification portion 8 of the side sheet 64. The identification unit 8A may be formed to exhibit the same color as that of the identification unit 8, but may be formed to exhibit a color different from that of the identification unit 8.

  By providing the identification unit 8A, the three-dimensional gather 7 can be easily identified from other parts even when the identification unit 8 of the side sheet 64 is difficult to visually recognize. Therefore, it becomes easy to put on the diaper 100 in a state where the three-dimensional gather 7 is properly raised. In addition, by providing the identification portion 8A in the portion of the inner layer sheet 52 that is close to the identification portion 8, it becomes easy for the wearer to identify the position to be applied to the buttocks. Can do.

  In addition, omitting the identification portion 8 of the side sheet 64 and providing only the identification portion 8A on the inner layer sheet 52 is not prevented. Moreover, you may provide an identification part in the top sheet 62 grade | etc., Of the absorption part 6 instead of the inner layer sheet | seat 52. FIG.

  The identification unit 8 can be easily provided by printing or coloring the corresponding part directly or attaching a material exhibiting a specific color when the side sheet 64 is manufactured. Therefore, it becomes possible to provide the diaper 1 that facilitates proper mounting at a low cost. Moreover, in the diaper 1, since it becomes easy to make the solid gathers 7 function appropriately, it can reduce that a bodily fluid leaks outside from the diaper 1. Therefore, since it is also possible to reduce wearers and the like by uniquely adding the absorbent member to the inside of the diaper 1, it is possible to suppress the generation of wasteful waste.
