First, as shown in FIGS. 5(a) and 5(b), the reversible mounting portion 16 is folded back toward the outer surface of the holder 10 so that the first surface 31 faces away from the wearer's skin.
At this time, the holder-side fastening structure 15 is also directed to the opposite side of the wearer's skin. In this state, the pad-side fastening structure 25 is pressed against the holder-side fastening structure 15 to fasten.
Then, as shown in FIGS. 1(a) and 1(b), the folding back of the reversible mounting portion 16 is released so that the first surface 31 faces toward the skin when worn. When the folding is released, the end region 20e of the absorbent pad 20 in the longitudinal direction X, which is integrated with the reversible mounting portion 16, faces the side opposite to the wearer's skin side, that is, the back sheet 22 side. folded back.
In this way, the absorbent pad 20 is attached to the holder 10, and the end region 20e of the absorbent pad 20 in the longitudinal direction X is folded back toward the backsheet 22 side, and the inner surface side of the holder 10 is formed. Positioned. This state is a preferred usage state of the diaper 1 of the present embodiment.

In the holder 10 of this embodiment, the pad-side fastening structure 25 of the absorbent pad 20 is fastened to the holder-side fastening structure 15 with the first surface of the reversible mounting portion 16 folded back toward the outer surface of the holder 10 . Therefore, the pad-side fastening structure 25 can be fastened to the holder-side fastening structure 15 with the holder-side fastening structure 15 facing the outer surface of the holder 10 as described above. . Therefore, it is possible to easily attach the absorbent pad 20 to the holder 10 . Also, when the absorbent pad 20 attached to the holder 10 is replaced with a new one, the first surface 31 of the reversible attachment portion 16 is folded back toward the outer surface of the holder 10, and the pad-side fastening structure 25 is attached. Since it can be removed from the holder-side fastening structure 15, the absorbent pad 20 can be easily replaced.

In addition, in the diaper 1 of the present embodiment, when the reversible attachment portion 16 of the holder 10 is unfolded, the end regions 20e of the absorbent pad 20 are reversibly attached as shown in FIGS. It is located on the side of the skin facing surface of the portion 16 . Therefore, when the diaper 1 is viewed from the non-skin facing side, the appearance of the diaper 1 becomes neat as shown in FIG. 1(a). Thus, the diaper 1 of this embodiment is excellent in appearance. In addition, since the end region 20e of the absorbent pad 20 is located on the skin-facing side of the reversible mounting portion 16, the holder 10 is less likely to be soiled by the wearer's excrement. Further, the pad-side fastening structure 25 and the holder-side fastening structure 15 are positioned on the side of the skin-facing surface of the holder 10 in a state where they are coupled. In other words, the pad-side fastening structure 25 and the holder-side fastening structure 15 are sandwiched between the holder 10 and the wearer's skin in a state in which they are combined. Unintentional separation from the holder 10 can be prevented, and the absorbent pad 20 can be prevented from coming off from the holder 10. - 特許庁

By locating the end region 20e of the absorbent pad 20 on the skin facing surface side of the reversible mounting portion 16, the absorbent pad 20 can be effectively used. This point will be described below.
For example, when the end region of the absorbent pad is attached to the non-skin facing surface of the holder as in the absorbent article of Patent Document 2, the height direction of the holder from the edge of the end region in the absorbent pad is located on the non-skin facing side of the holder.
On the other hand, in the diaper 1 of this embodiment, as shown in FIGS. 1(a) and 1(b), the end region 20e of the absorbent pad 20 is located on the side of the holder 10 facing the skin. Therefore, the length in the vertical direction X of the portion of the absorbent pad 20 located on the skin-facing side of the holder 10 can be relatively long, and the portion of the absorbent pad 20 that is in direct contact with the wearer's skin. can be made longer, the absorbent pad 20 can be effectively utilized.
Thus, the diaper 1 of the present embodiment has an excellent appearance, the holder 10 is less likely to become dirty, the absorbent pad 20 is less likely to come off from the holder 10, and the absorbent pad 20 can be effectively utilized.

In the diaper 1 of this embodiment, the absorbent pad 20 has an end flap portion 20f in an end region 20e in the longitudinal direction X, as shown in FIGS. 4(a) and 4(b). It is preferable to have the pad-side fastening structure 25 on the surface of the portion 20f on the side of the top sheet 21 . One or both of the topsheet 21 and the backsheet 22 extend from the end of the absorber 23 to form the end flap portion 20f. The advantages of the absorbent pad 20 having the end flap portion 20f and the end flap portion 20f having the pad-side fastening structure 25 are as follows. Since the end flap portion 20f does not include the absorber 23, it is thinner than the portion of the absorbent pad 20 other than the end flap portion 20f. Therefore, after the pad-side fastening structure 25 is fastened to the holder-side fastening structure 15, when the end region 20e having the pad-side fastening structure 25 is folded back toward the back sheet 22, the end region 20e is folded back. In addition, the thickness of the end regions 20e can be made relatively thin when the diaper 1 is folded back, so that the wearer is less likely to feel uncomfortable when wearing the diaper 1.例文帳に追加

The absorbent pad 20 preferably has two or more pad-side fastening structures 25 on the skin-facing surface side. This allows the absorbent pad 20 to be more securely attached to the holder 10 . From the viewpoint of achieving this effect more remarkably, the number of pad-side fastening structures 25 provided on the skin-facing side of the absorbent pad 20 is preferably 2 or more, more preferably 4 or more, and more preferably 4 or more. Preferably, it is 6 or more. The upper limit of the number of pad-side fastening structures 25 that the absorbent pad 20 has on the skin-facing surface side can be set to ten.
Also, as shown in FIG. 4(b), the absorbent pad 20 preferably has one or more second fastening structures 26 on the non-skin facing side. The second fastening structure 26 is attached to the non-skin facing surface of the absorbent pad 20 by folding back at least the portion having the pad-side fastening structure 25 of the end region 20e of the absorbent pad 20 toward the back sheet 22 side. It is a fastening structure used for wearing. The second fastening structure 26 is preferably located in the end region 20e. The second fastening structure 26 can be provided at a portion facing the folded end region 20e instead of being provided at the end region 20e. By having the second fastening structure 26, as shown in FIG. 1(b), when the diaper 1 is worn, the folded state of the end region 20e of the absorbent pad 20 is stably maintained. , the preferable use condition of the diaper 1 is stably maintained.

In the holder 10, the length F1 of the front body F and the length R1 of the back body R may be the same or different in the height direction HD. When the length F1 of the front body F is different from the length R1 of the back body R, the length F1 of the front body F may be longer than the length R1 of the back body R, or the length of the front body F may be longer than the length R1 of the back body R. The length F1 may be shorter than the length R1 of the back body R. In general, the wearer's excretory part, such as the urethral opening, is located on the abdomen of the wearer. Therefore, from the viewpoint of making the holder 10 less likely to get dirty, the length F1 of the front body F is preferably short. The length R1 of the back body R is preferably long from the viewpoint that the back body R properly covers the wearer's buttocks and gives the wearer a sense of security. That is, from the viewpoint of compatibility between these, the length F1 of the front body F is preferably shorter than the length R1 of the back body R. More specifically, the length F1 of the front body F is preferably 80% or less, more preferably 75% or less, still more preferably 70% or less of the length R1 of the back body R. As for the lower limit of the length F1 of the front body F, F1 can be 50% of the length R1 of the back body R. When the diaper 1 or holder 10 is for adults, the length F1 of the front body F is preferably shorter than the length R1 of the back body R by 5 cm or more, more preferably 6 cm or more, and 7 cm or more. is more preferred.

It is preferable that the holder 10 is made of an expandable member that expands and contracts in the height direction HD and the circumferential direction CD. By doing so, the fit of the holder 10 can be improved. Moreover, since the absorbent pad 20 can be pulled up when the diaper 1 is put on, the fit of the absorbent pad 20 can also be improved. From the viewpoint of achieving these effects more remarkably, the expansion/contraction rate of the expansion/contraction member constituting the holder 10 is preferably 10% or more, more preferably 15% or more, and still more preferably 20% or more. The upper limit of the expansion ratio of the holder 10 can be set to 40%.

First, in a natural state, two marks are made on the outer surface of the holder 10 with a permanent marker or the like at a constant interval L0 (eg, 100 mm) in the direction of expansion and contraction of the holder 10 . Then, the marked portion of the holder 10 is clamped by a chuck of a tensile tester (manufactured by Shimadzu Corporation, model number: Autograph AG-X). Next, the chuck-to-chuck distance is increased at a speed of 300 mm/min, and the chuck-to-chuck distance when the tensile load reaches 3N is defined as L1. Then, the expansion ratio is calculated by the following formula.
Stretch ratio = (L1-L0)/L0

It is also preferable that the holder 10 has liquid absorbency. By doing so, the holder 10 can absorb sweat while the diaper 1 is being worn, so discomfort due to sweat can be reduced even when the diaper 1 is worn for a long period of time. Here, having liquid absorbability means that when a drop (approximately 0.05 cc) of physiological saline is dropped using a Komagome pipette or the like, the liquid It means that the drops are absorbed and become invisible. As a method of imparting liquid absorbency to the holder 10 , for example, a member having liquid absorbency may be used as the outer layer sheet 13 or the inner layer sheet 12 . Examples of the absorbent material include cotton, polyester, and the like.

The present invention is not limited to the above embodiments, and can be modified as appropriate without departing from the scope of the present invention.
For example, the holder of the present invention may be worn in a ring shape around the wearer's waist when in use, and may not be in a ring shape when not in use. For example, the holder main body 11 has a belt-like shape elongated in one direction, and one end and the other end in the longitudinal direction of the holder main body 11 are detachably connectable. At the time of mounting, the holder main body 11 may be formed into an annular shape by connecting one end and the other end in the longitudinal direction of the holder main body 11 . Alternatively, the holder main body 11 is divided into a plurality of members (for example, a member corresponding to the front body F and a member corresponding to the back body R) in the circumferential direction CD, and the plurality of members can be detachably attached to each other in one direction. The plurality of members may be connected to each other to form the ring-shaped holder main body 11 during use (mounting).

Further, the shape of the front body F and the back body R of the holder 10 in the maximum stretched state in plan view is not particularly limited, and may be a substantially rectangular shape or the like. Also, the front body F and the back body R may have the same shape and the same size in plan view.

In the above embodiment, both the outer layer sheet 13 and the inner layer sheet 12 have a single layer structure, but in the present invention, one or both of the sheets 12 and 13 may have a laminated structure. For example, the outer layer sheet 13 may have a laminated structure of two or more sheets including a sheet having stretchability in the lateral direction Y, and the inner layer sheet 12 may have a single layer structure made of a non-stretchable sheet.

In the above-described embodiment, the holder 10 includes the outer layer sheet 13 and the inner layer sheet 12 as the sheet-like members forming the holder main body 11. However, in the present invention, sheet-like members other than the two sheets 12 and 13 are used. may contain. Specifically, for example, the holder 10 (holder main body 11) has a function of being arranged in a region corresponding to the wearer's waist on the skin-facing surface (inner surface) of the holder 10 in addition to the sheets 12 and 13. may include sex sheets. The functional sheet has, for example, at least one of various functions such as sweat absorption, moisture absorption, antibacterial properties, and deodorant properties.

In the above embodiment, the holder-side fastening structure 15 is the female member of the mechanical hook-and-loop fastener, and the pad-side fastening structure 25 is the male member of the mechanical hook-and-loop fastener. The fastening structure 15 may be a male member of a mechanical hook-and-loop fastener, and the pad-side fastening structure 25 may be a female member of a mechanical hook-and-loop fastener. As the second fastening structure 26, the aforementioned male member of the mechanical hook-and-loop fastener or the like can be used. It is preferable that the surface to which the second fastening structure 26 is attached is provided with a female member of a highly engaging nonwoven fabric or a mechanical hook-and-loop fastener.

A pair of leak-prevention cuffs may be arranged on both sides of the absorbent pad 20 along the longitudinal direction X so as to stand on the wearer's skin side when the diaper 1 is worn. Each leak-preventing cuff may include a sheet for forming a leak-preventing cuff, which is the main body of the leak-preventing cuff, and an elastic member fixed to the sheet in an elongated state in the longitudinal direction X.

In the above-described embodiment, the planar view shape of the absorbent pad 20 is a substantially hourglass shape in which the length in the horizontal direction Y is shorter in the central region in the vertical direction X than in the end regions 20e in the vertical direction X. The planar view shape of the sexual pad 20 is not limited to this, and may be, for example, a substantially rectangular shape.
