  Hereinafter, preferred embodiments of the present invention will be described with reference to the drawings.

<1. Diaper according to one embodiment>
Drawing 1 is a top view which looked at diaper 1 concerning one embodiment of the present invention from the skin side in the state where it developed. FIG. 2 is a plan view of the diaper 1 as viewed from the outside in the unfolded state. 3 is a cross-sectional view of the diaper 1 as viewed from the position III-III in FIG. As shown in FIGS. 1-3, the diaper 1 is provided with the pad 10 addressed to a wearer's crotch, and the strip | belt member 20 supported by a wearer's waist circumference.

  The pad 10 includes a liquid-permeable top sheet 11 disposed on the skin side, a liquid-impermeable back sheet 12 disposed on the outside, and an absorber 13 interposed between the sheets 11 and 12. Have. The urine excreted from the wearer of the diaper 1 passes through the top sheet 11, but does not penetrate outside from the back sheet 12, and is absorbed and held by the absorber 13 between the top sheet 11 and the back sheet 12. The

  The top sheet 11 is made of, for example, a nonwoven fabric that is made liquid permeable by treating the surface of hydrophobic fibers (polypropylene, polyethylene, polyester, polyamide, nylon, etc.) with a surfactant. The top sheet 11 may be made of a nonwoven fabric using hydrophilic fibers (cellulose, rayon, cotton, etc.).

  The back sheet 12 is made of, for example, a plastic film. In addition, the back sheet 12 may be comprised by the plastic film and the highly flexible nonwoven fabric affixed on the outer surface. The back sheet 12 may be made of a water-repellent nonwoven fabric using hydrophobic fibers (polypropylene, polyethylene, polyester, polyamide, nylon, etc.).

  The absorber 13 is fixed between the top sheet 11 and the back sheet 12 with an adhesive (not shown). The absorbent body 13 is, for example, a lump obtained by mixing hydrophilic fibers such as pulverized pulp fibers and cellulose fibers and granular superabsorbent polymer (SAP), a paper sheet such as tissue paper, or a liquid-permeable material. It is coated with a non-woven sheet. The absorbent body 13 may be formed by molding only a superabsorbent polymer into a sheet shape.

  The pad 10 includes a front body portion 10a addressed to the wearer's abdomen, a back body portion 10b addressed to the wearer's buttocks, and a crotch portion 10c connecting the front body portion 10a and the back body portion 10b. Have. Hereinafter, a direction in which the front body part 10a, the crotch part 10c, and the back body part 10b are connected is referred to as a “longitudinal direction”. A direction perpendicular to the longitudinal direction and along the surface of the pad 10 is referred to as a “width direction”. The pad 10 extends in the longitudinal direction from the front body part 10a to the back body part 10b, and has a shape constricted in the width direction at the crotch part 10c located in the middle.

  A front securing portion 14 is provided on the outer side surface of the front body portion 10a. The front fixing part 14 is a part where a front fixing part 24 of the band member 20 described later is detachably fixed. Further, a rear attachment portion 15 is provided on the outer surface of the rear body portion 10b. The rear part 15 is a part where a rear part 23 to be described later is detachably fastened. The front to-be-fixed part 14 and the back to-be-attached part 15 are comprised by the loop material of a hook_and_loop | surface fastener, for example, and are joined to the outer surface of the back seat | sheet 12 with the adhesive agent (illustration omitted).

  The band member 20 is a member that is attached to the waist of the wearer in order to fix the pad 10 between the wearer's crotch. As shown in FIG. 3, the belt member 20 has two belt-like sheets 21 and 22 extending in the width direction. The belt-like sheets 21 and 22 are overlapped on the skin side and the outside, and are joined to each other by a water-resistant adhesive or stitching.

  A rear fastening portion 23 is provided on the skin side surface in the vicinity of the center of the band member 20 in the width direction. The rear fastening part 23 is detachably fastened to the rear fastening part 15 of the pad 10. The rear fastening part 23 is made of, for example, a hook material of a hook-and-loop fastener, and is joined to the skin side surface of the belt-like sheet 21 by a water-resistant adhesive or stitching. When using the diaper 1, the pad 10 and the band member 20 are integrated by fastening the rear fastening part 23 to the rear fastening part 15. Further, as shown in FIG. 4, after use, the rear fastening part 23 can be peeled off from the rear fastening part 15 to separate the pad 10 and the band member 20.

  At both ends in the width direction of the band member 20, two tongue-shaped tab portions 20 a that protrude outward in the width direction are formed. A front fastening portion 24 is provided on the skin side surface of each knob portion 20a. The front fastening part 24 is detachably fastened to the front fastening part 14 of the pad 10. The front fastening part 24 is made of, for example, a hook material of a hook-and-loop fastener, and is joined to the skin side surface of the belt-like sheet 21 by a water-resistant adhesive or stitching.

  FIG. 5 is a view showing a state in which the front fastening part 24 is fastened to the front fastened part 14. When the diaper 1 is worn, the rear fastening part 23 is fastened to the rear fastening part 15 in advance, and the pad 10 and the band member 20 are integrated. Next, the pad 10 is placed between the crotch of the wearer. Then, the both ends of the width direction of the strip | belt member 20 are pulled out to a wearer's ventral side along a wearer's waist circumference. Then, the four front fastening parts 24 are respectively attached to arbitrary positions of the front fastening part 14 of the pad 10. As a result, the band member 20 is supported around the waist of the wearer, and the pad 10 is securely placed between the wearer's crotch.

  In addition, the front to-be-fastened part 14 has a fastening surface wider than the total area of the four front to-be-fastened parts 24. FIG. For this reason, a wearer can adjust the fastening position of the four front fastening parts 24 according to a body shape.

  The belt-like sheets 21 and 22 are both made of woven fabric. Since the woven fabric is made by interweaving thread-like fibers, it has higher resistance to washing than the nonwoven fabric. The fibers constituting the woven fabric of the belt-like sheets 21 and 22 may be natural fibers such as cotton, hemp, silk, and wool, or may be chemical fibers such as polyester, acrylic, and rayon. Moreover, what mixed the natural fiber and the chemical fiber may be used.

  As described above, the belt member 20 can be attached to and detached from the pad 10. For this reason, after the diaper 1 is used, the pad 10 and the band member 20 can be separated and only the pad 10 can be discarded. The belt-like sheets 21 and 22 of the belt member 20 are made of washable woven fabric. For this reason, the band member 20 can be washed, and the new pad 10 can be attached to the band member 20 after washing.

  Thus, the wearer can use the band member 20 repeatedly. This reduces the economic burden on the wearer. Moreover, compared with the case where the whole diaper is made disposable, the amount of garbage discarded is reduced and resources are effectively used. This contributes to the global environment.

  When the diaper 1 is replaced, a particularly large tensile stress acts on the band member 20. For this reason, it is preferable to use a material that is less likely to break against tensile stress than the top sheet 11 or the back sheet 12 of the pad 10 for the woven fabric that forms the belt-like sheets 21 and 22. On the other hand, with respect to the pad 10, the demand for strength against tensile stress can be suppressed. For this reason, the pad 10 can be designed to be thinner.

  Between the two belt-like sheets 21 and 22 of the belt member 20, a plurality of elastic members 25 that extend and contract in the width direction (the direction along the wearer's waist) are provided. The elastic member 25 is attached between the two belt-like sheets 21 and 22 in a state where the elastic member 25 is extended beyond the natural length. For this reason, the plurality of elastic members 25 generate an elastic force so as to shrink the band member 20 in the width direction. When the diaper 1 is worn, the belt member 20 is gently fitted around the waist of the wearer by the elastic force of the elastic member 25. Moreover, also when a wearer changes a attitude | position, the strip | belt member 20 follows a wearer's operation | movement favorably. For the elastic member 25, for example, natural rubber or polyurethane rubber is used.

  As shown in FIGS. 2 and 3, the elastic member 25 is provided at a position outside the rear fastening portion 23 in the width direction. In other words, the belt member 20 has a pair of stretchable regions 20b in which the elastic member 25 is provided at a position outside the rear fastening portion 23 in the width direction. The band member 20 has a non-stretchable region 20c in which the elastic member 25 is not provided between the pair of stretchable regions 20b, and the rear fastening portion 23 is provided in the non-stretchable region 20c.

  The stretchable region 20b of the belt member 20 fits well to the left and right side waist portions having a particularly large curvature among the waist circumference of the wearer. On the other hand, the contraction force of the elastic member 25 does not act on the rear fastening portion 23 provided in the non-stretchable region 20 c of the band member 20. For this reason, the rear fastening part 23 can be favorably attached to and detached from the rear fastening part 15 of the pad 10.

<2. Modification>
Although one embodiment of the present invention has been described above, the present invention is not limited to the above embodiment.

  In said embodiment, the strip | belt member 20 was an integral member containing the site | part addressed to a wearer's right waist part, and the site | part addressed to a wearer's left waist part. In this way, the band member 20 can be easily manufactured as an integral member. Moreover, the rear fastening part 23 and the rear fastening part 15 are sufficient in one place, respectively. However, the band member 20 may be composed of a plurality of separate members.

  For example, as shown in FIG. 6, the belt member 20 may be composed of a right belt member 26 addressed to the wearer's right waist and a left belt member 27 addressed to the wearer's left waist. . In this way, the band member 20 can be narrowed as a whole. For this reason, the quantity of the woven fabric used for the strip | belt member 20 can be suppressed.

  Further, as shown in FIG. 7, the band member 20 may have a convex portion 20 d that protrudes in a trapezoidal shape toward the crotch side outside the back body portion 10 b. If it does in this way, the wider area | region of a wearer's buttocks surface can be coat | covered with the convex part 20d. Moreover, since the shape of the diaper 1 approaches pants, the discomfort in appearance can be reduced.

  However, the area where the pad 10 and the belt member 20 overlap is smaller in the above embodiment than in the example of FIG. For this reason, in terms of air permeability with respect to the wearer's skin, the above embodiment is preferable to the example of FIG. In addition, the body fluid is less likely to adhere to the band member 20 in the above embodiment than in the example of FIG. For this reason, the frequency | count of washing of the strip | belt member 20 can be reduced.

  Moreover, in said embodiment, the hook_and_loop | surface fastener was mentioned as an example of the front to-be-attached part 14, the back to-be-attached part 15, the front to-be-attached part 24, and the back to-be-attached part 23. FIG. If a hook-and-loop fastener is used, sufficient fastening strength can be obtained and attachment / detachment is easy. However, other detachable fastening means such as hooks and buttons may be used for these fastening parts and to-be-fastened parts.

  Moreover, as long as it can fix | attach directly with respect to the sheet | seat which comprises the pad 10 or the strip | belt member 20, you may abbreviate | omit one of a fixation part and a to-be-fixed part. For example, when the outer surface of the back sheet 12 of the pad 10 is composed of a nonwoven fabric, it is possible to directly attach the hook material to the nonwoven fabric. For this reason, as shown in FIG. 8, the front fastening part 24 and the rear fastening part 23 are directly provided on the outer surface of the back sheet 12 without providing the front fastening part 14 and the rear fastening part 15. You may make it fix. In this way, the structure of the diaper 1 can be further simplified.

  However, as in the above-described embodiment, if the front attachment portion 14 and the rear attachment portion 15 having a higher attachment force than other parts are provided, the front attachment portion 24 and the rear attachment portion 23 are It is preferable at the point which can be fixed more firmly.

  In the above embodiment, the center position of the band member 20 is fixed to the back body part 10 b of the pad 10, and both end parts of the band member 20 are fixed to the front body part 10 a of the pad 10. If it does in this way, the both ends of the belt member 20 can be fixed on the abdomen side of the wearer who is easy to operate. However, the center position of the band member 20 may be fixed to the front body part 10 a of the pad 10, and both end parts of the band member 20 may be fixed to the rear body part 10 b of the pad 10.

  In the above embodiment, both end portions of the band member 20 are fixed to the pad 10. However, as shown in FIG. 9, the other end may be fixed to one end of the band member 20. In the example of FIG. 9, one end of the band member 20 is extended from the pad 10 to the outside in the width direction. Then, the fastening portion 28 provided on the skin side surface of the one end portion of the belt member 20 is fastened to the to-be-attached portion 29 provided on the outer side surface of the other end portion. In the example of FIG. 9, a front fastening portion 24 that is detachably fastened to the front secured portion 14 is provided on the inner side in the width direction of the securing portion 28.

  Moreover, in said embodiment, although the strip | belt member 20 was formed in the substantially rectangular shape extended in the width direction, the strip | belt member 20 may be formed in the annular | circular shape previously. However, it is preferable that the substantially rectangular band member 20 is wound around the waist of the wearer because it can accommodate more body shapes.

  In the above embodiment, the elastic member 25 is attached between the two belt-like sheets 21 and 22 of the belt member 20. However, the elastic member 25 may be woven into the belt-like sheets 21 and 22. Moreover, the strip | belt-shaped sheets 21 and 22 themselves may be comprised with the woven fabric which has a stretching property. The band member 20 may be composed of a single layer sheet.

  Moreover, in order to improve the fitting property of the pad 10 with respect to a wearer, the elastic member may be provided in the pad 10. Further, in order to prevent leakage of urine from the pad 10, a pair of water-repellent sheets (so-called three-dimensional gathers) that stand up may be provided on the skin surface side of the pad 10.

  The diaper 1 may absorb not only urine but also other body fluids such as loose stool and menstrual blood. Moreover, the diaper 1 may be intended for adults or may be intended for infants.

  Moreover, you may combine suitably each element which appears in the above embodiment and modification.
