Some of these deployable diapers are intended for infants and young children. For example, if the wearer is a baby born with a low birth weight of 3,000 grams or less in the NICU (low birth weight baby), the low birth weight baby will remain in the womb surrounded by medical equipment in an incubator. In other words, the patient is often in a prone position (positioning posture) with the abdomen facing down, both legs bent, and the knees pulled close to the abdomen. In addition, depending on the baby's low birth weight, the concept of minimum handling, in which it is desirable not to touch the baby's body, may be applied to prevent unnecessary stress. In that case, the diaper is worn in the above positioning posture.

When a deployable diaper is worn by a low birth weight baby who is in a positioning posture, it is difficult to lock the fastening tape on the abdomen hidden between the legs. Therefore, there is a method of making a low birth weight baby wear a diaper by turning the diaper upside down and locking a fastening tape on the back side of the low birth weight baby. In this case, the diaper is placed on the ventral side of the low birth weight infant with the front and back reversed, but it may be difficult to determine how far into the body the diaper should be inserted on the ventral side to ensure stable attachment. be.

Furthermore, even when putting a diaper on a low birth weight infant who is lying on his back, in special circumstances such as when the body is connected to medical equipment in an incubator, it is not enough to simply indicate the order in which the diaper should be put on, as in Patent Document 1. , it may be difficult to achieve an appropriate attachment state to the baby's body. If the diaper is not properly fitted, not only will the diaper not fit properly, but the designs on the outside of the diaper will also wrinkle and lose their original design. , there is a risk that the diaper will look less like a dress and look more like an article.

This diaper 1 is a diaper 1 specialized for low birth weight infants weighing 3000 grams or less, and is an expandable diaper 1 that is attached to a wearer (low birth weight infant) using a fastening tape 40.

Note that the unfolded state of the diaper 1 refers to a state in which the diaper 1 is unfolded on a plane by opening the diaper 1 in its longitudinal direction. In addition, the stretched state of the diaper 1 is a state where the diaper 1 is stretched to such an extent that the wrinkles that have occurred in the diaper 1 are substantially no longer visible in the unfolded state of the diaper 1, and each member constituting the diaper 1 is The diaper 1 is in a state in which the diaper 1 is stretched until the dimensions of (for example, the side sheets 6 to be described later) match or are close to the dimensions of the individual members.

<<Basic configuration of diapers>>
In the unfolded state shown in FIG. 1, the diaper 1 has a longitudinal direction, a width direction, and a thickness direction that are orthogonal to each other, and includes, from one side in the longitudinal direction, a first waist portion 1A, a crotch portion 1C, and a second crotch portion 1C. The waist portion 1B are arranged side by side. Moreover, the thickness direction is the direction in which the members constituting the diaper 1 are laminated, as shown in FIG. 2A and the like. In the thickness direction, the side that contacts the wearer is called the "skin side", and the opposite side is called the "non-skin side".

As shown in FIG. 2A, the diaper 1 includes an absorbent body 2 that absorbs excreted liquid such as urine, a liquid-permeable top sheet 3 that covers the absorbent body 2 from the skin side, and a liquid-permeable top sheet 3 that covers the absorbent body 2 from the non-skin side. A liquid-impermeable leak-proof sheet 4 (hereinafter also referred to as "back sheet 4") that covers, an exterior sheet 5 that covers the leak-proof sheet 4 from the non-skin side and forms the outer shape of the diaper 1, and a top sheet 3 It has a pair of side sheets 6 provided side by side in the width direction.

The top sheet 3 can be exemplified by an air-through nonwoven fabric, the leak-proof sheet 4 can be exemplified by a resin film such as a polyethylene film, and the exterior sheet 5 and side sheet 6 can be an SMS nonwoven fabric (spunbond/melt blown). Examples include flexible sheets such as /spunbond nonwoven fabric).

As shown in FIG. 1, the absorbent body 2 has a substantially rectangular shape in plan view and is provided at the center in the width direction. The absorbent body 2 includes an absorbent core 2A and a core wrap sheet 2B that covers the outer peripheral surface of the absorbent core 2A. The absorbent core 2A is formed by molding a liquid absorbent material into a substantially hourglass shape when viewed from above, and has a constricted portion 2c between one end 2ga and the other end 2gb in the longitudinal direction. The widthwise dimension of the constricted portion 2c is smaller than the widthwise dimensions of the one end 2ga and the other end 2gb. Moreover, the absorbent core 2A has notches (notches 71, 72, and 73, which will be described later). Examples of liquid-absorbing materials include liquid-absorbing fibers such as pulp fibers containing superabsorbent polymers (so-called SAP). Examples of the core wrap sheet 2B include liquid-permeable tissue paper and nonwoven fabric, but the absorbent body 2 may not include the core wrap sheet 2B.

Side flaps 20 are provided on both sides of the absorbent body 2 in the width direction. As shown in FIG. 2A, the side flap 20 is made up of the side sheet 6 and a part of the exterior sheet 5. The side flaps 20 include a pair of first extending portions 20A that extend outward in the width direction from the crotch portion 1C in the first waist portion 1A, and a pair of first extending portions 20A extending outward in the width direction from the crotch portion 1C in the second waist portion 1B. A pair of second extending portions 20B extending outward. Further, fastening tapes 40 are fixed to each of the outer ends in the width direction of the pair of first extending portions 20A.

The fastening tape 40 has a tape base material 41 and a hook material 42. The tape base material 41 is, for example, a member made of nonwoven fabric, and has a substantially rectangular shape that is long in the width direction. The hook material 42 (for example, a male member of a hook-and-loop fastener) is provided on the skin side of a portion of the tape base material 41 that protrudes outward in the width direction from the first extending portion 20A of the side flap 20.

This fastening tape 40 can engage with a target area 45 (see FIG. 1), which is a predetermined area provided on the non-skin side of the exterior sheet 5 in the second waist portion 1B. In this embodiment, the exterior sheet 5 is made of a nonwoven fabric, so that the hook material 42 can be directly engaged with the exterior sheet 5 (target area 45). However, the present invention is not limited to this, and a member, such as a female member of a hook-and-loop fastener, to which the hook material 42 is easily locked may be provided separately from the exterior sheet 5. Moreover, instead of the hook material 42, for example, adhesive tape may be provided on the fastening tape 40.

When wearing the diaper 1, the unfolded diaper 1 is applied to the wearer's body and folded in half at approximately the center position CL2 (see FIG. 1) in the longitudinal direction, and the diaper 1 is folded in half at the first waist portion 1A side. The first extending portion 20A is folded back inward in the width direction. Then, each hook material 42 provided on the pair of fastening tapes 40 is latched to a target area 45 provided on the non-skin side surface of the second waist portion 1B. Thereby, a waist opening and a leg opening of the diaper 1 are formed, and the position of the diaper 1 can be fixed with respect to the wearer's body (torso).

The diaper 1 also has a pair of three-dimensional gathers 50 as leak-proof walls at positions on both sides in the width direction. As shown in FIG. 3, each three-dimensional gather part 50 includes an elastic member 51 (for example, thread rubber) for the three-dimensional gather part 50 that is stretchable in the longitudinal direction, and is located at both ends in the longitudinal direction, and a pair of first proximal end portions 52 that cannot stand up; It has a second base end portion 53 and a standing portion 54 that can stand up on the skin side in the thickness direction.

The first base end portion 52 and the second base end portion 53 have an elongated rectangular shape in the longitudinal direction, and are formed by fixing the side sheet 6 to the top sheet 3. Examples of the fixing method include well-known methods such as adhesion with hot melt adhesive and welding. Note that in FIG. 3, two first base end portions 52 are lined up in the width direction at each end of each three-dimensional gather portion 50 in the longitudinal direction, but the number is not limited to two.

Further, as shown in FIG. 2B, the inner side portion of the side sheet 6 in the width direction is folded back toward the skin side, and between the two layers of the side sheet 6, there is a space for the three-dimensional gathers portion 50. An elastic member 51 is fixed in a stretched state in the longitudinal direction. Therefore, the upright portion 54, which is a portion of the side sheet 6 between the pair of first base end portions 52 of each three-dimensional gather portion 50, moves in the thickness direction with the second base end portion 53 as a fulcrum due to the contraction of the elastic member 51. stand on the skin side. In addition, although the number of elastic members 51 which each three-dimensional gather part 50 has in FIG. 3 is one, it is not limited to this and a plurality of elastic members 51 may be lined up in the width direction.

In addition, a pair of leg elastic members 7 (for example, rubber thread) that are stretchable in the longitudinal direction are placed on both sides of the diaper 1 in the width direction, mainly at the crotch area 1C, along the wearer's legs. is provided. The leg elastic member 7 is fixed to the non-skin side surface of the side sheet 6 in a stretched state in the longitudinal direction. Therefore, when the diaper 1 is worn, each side portion of the diaper 1 in the width direction fits around the wearer's legs, and leakage of excrement is suppressed. In addition, in FIG. 1, two leg elastic members 7 are lined up in the width direction on each side of the diaper 1 in the width direction, but this number is not limited to two.

In the above description, rubber thread is used as an example of the elastic member 51 for the solid gather portion 50 and the leg elastic member 7, but the elastic member 51 is not limited to this. These elastic members 51 and 7 may be, for example, thread-like polyurethane stretchable fibers, a stretchable film made by melting a thermoplastic elastomer resin, or a stretchable nonwoven fabric made of stretchable fibers.

Moreover, as shown in FIG. 1, the diaper 1 has a perforation line 60 for cutting a portion (a portion indicated by a dotted line) to which the fastening tape 40 is fixed to the first waist portion 1A. In addition, since the diaper 1 has a pair of fastening tapes 40, it also has a pair of perforation lines 60. The perforation line 60 of this embodiment is formed as a perforation, and a part of the diaper 1 can be easily separated from the main body along the perforation line 60.

The perforation line 60 is used especially when removing the diaper 1 from a low birth weight baby. That is, there is a concept that it is desirable for low birth weight babies born with a low birth weight of 3,000 grams or less (particularly less than 2,500 grams) to spend their time lying face down in the same position as they were in the womb. The baby's posture while in the womb is with the belly facing down, the back rounded in a C shape, the legs bent in an M shape, and the knees pulled together so that they touch the abdomen. . Hereinafter, such a posture peculiar to low birth weight infants will also be referred to as a "positioning posture" (see FIG. 9B described later).

For example, when a diaper is worn on a low birth weight baby who is in a positioning posture (refer to "front and rear reverse wearing" described below, FIG. 9B), the fastening tape 40 is locked on the wearer's back side. However, by cutting the perforation line 60, the diaper 1 is unfolded in the longitudinal direction with the fastening tape 40 being secured to the second waist portion 1B located on the back side. Therefore, the diaper 1 can be pulled out without passing the first waist portion 1A (in this case, the ventral side) to which the hard fastening tape 40 is fixed between the legs of the low birth weight baby, thereby preventing contact with the skin of the low birth weight baby. It can reduce the burden.

Further, the absorbent body 2 (absorbent core 2A) shown in FIG. 1 is provided with a pair of notches 71 at the center in the longitudinal direction and at both ends in the width direction. Similarly, a pair of notches 72 are provided at both ends in the width direction between the longitudinal center portion and one end portion 2ga, and between the longitudinal center portion and the other end portion 2gb. A pair of notches 73 are provided at both ends of the holder. It is not necessary to provide three pairs (71, 72, 73) of notches as in this embodiment, and any number of notches may be provided. Each notch (71, 72, 73) is formed in a chevron shape toward the inner side in the width direction at both ends of the absorber 2 in the width direction, but the shape is not limited to the shape shown in FIG. do not have. Furthermore, in this embodiment, the absorbent core 2 (absorbent core 2A) is cut out at each notch (71, 72, 73), but the liquid absorbent material is smaller than other parts of the absorbent core 2. It may be formed by reducing the basis weight. The pair of notches (71, 72, 73) can prevent the absorbent core 2A from twisting and create a gap between the diaper 1 and the wearer, thereby suppressing leakage of excrement.

<<When normally wearing the front and back of the diaper>>
When a deployable diaper is worn by a low-weight infant in a supine position, the diaper is usually spread out in the longitudinal direction, and then the low-weight infant is placed on the diaper while lying face up. At that time, the wearer is worn so that the first waist portion 1A to which the fastening tape 40 is fixed covers the back side, and the second waist portion 1B covers the ventral side. Here, the case where the first waist portion 1A is worn as usual so as to cover the back side is referred to as "front and rear normal wear".

On the other hand, low birth weight infants in NICUs are often connected to medical equipment in incubators, and even when wearing normal clothing at the front and back, under such circumstances, the bodies of low birth weight infants are However, it may be difficult to achieve an appropriate wearing state. If the diaper is not properly fitted, there is a risk that the diaper will not fit the body and there is a possibility of leakage, but also that the diaper will look less like a garment and feel more like an item. . In many cases, no clothing other than diapers is worn inside the incubator, so for parents of low birth weight infants who are watching from outside the incubator, underwear is more important than wearing them unsteadily and making them look like medical items. Seeing something similar to that can easily lead to a sense of security.

On the other hand, the diaper 1 of this embodiment is provided with a wearing indicator 100 that can be visually recognized by a person changing the diaper 1 (such as a nurse) when wearing the diaper 1 (see FIG. 1 and FIG. 7 described later). The fitting index 100 serves as a guide for how far the diaper 1 should be inserted and at what position on the body of the low weight baby when the diaper 1 is inserted under the body of the low weight baby.

The wearing index 100 in FIG. 1 is a wearing index 100 (hereinafter referred to as "wearing index 100A") that is visible from the skin side of the diaper 1 by a person changing the diaper 1 (a nurse, etc.), and the wearing index 100A is It is provided in the first waist portion 1A. The wearing index 100A is an index used as a guide when normally worn on the front and back, and the first waist portion 1A corresponds to the dorsal side portion here.

FIG. 4 is a diagram illustrating the structure of the human pelvis. FIG. 5 is a diagram when the diaper 1 is put on a low birth weight infant in a supine position. The structure of the human pelvis in FIG. 4 here means the structure of the pelvis of a low birth weight baby who is the wearer. The wearing index 100A shown in FIG. 1 is based on the iliac crest Pa of the ilium P of the low birth weight baby shown in FIG. 4 and the acetabulum Q in the longitudinal direction of the diaper 1. It serves as a landmark when pulling into the baby's dorsal side. Specifically, as shown in FIG. 5, when the diaper 1 is attached to a low birth weight infant in a supine position, the attachment indicators 100A become visible from both sides of the abdomen of the infant. The person changing the diaper inserts the diaper 1 under the child's body, and while visually checking the fitment indicator 100A, makes sure that the fitment indicator 100A is between the infant's iliac crest Pa and the acetabulum Q as shown in FIG. The diaper 1 is pulled in so as to come into contact with the region X, and the baby is put on it. The iliac crest Pa is the most outwardly protruding part of the ilium P, and the protruding part is easily noticeable when touching the lower back. The acetabulum Q is a cup-shaped recess that serves as a receptacle for the femoral head, and together with the femoral head forms the hip joint.

By attaching the diaper 1 so that the attachment index 100A abuts between the iliac crest Pa and the acetabulum Q of a low birth weight infant, the diaper 1 is inserted into the infant's body appropriately. This makes it easier to achieve a stable wearing state, and reduces stress on the wearer, such as a nurse, when changing diapers. In addition, by stably wearing the device, parents and others watching over the device can easily feel the feeling of wearing clothes.

In addition, although the attachment indicator 100A shown in FIG. 1 uses a triangular indicator as an example, it is not limited to this in any way, and an indicator of any shape that is easily visible to the person changing the diaper 1 can be used.

Moreover, as shown in FIG. 1, a pair of attachment indicators 100A are provided on both sides of the diaper 1 in the width direction, and are arranged symmetrically with respect to the center in the width direction (center position CL1). The center CL1 in the width direction of the diaper 1 is a position corresponding to the center of the body of the low birth weight infant who is the wearer, and a pair of attachment indicators 100A are placed on both sides in the width direction, and the position is symmetrical with respect to the center CL1. By doing so, it is possible to confirm the deviation in the width direction from the center of the body of a low birth weight infant. In addition, the wearing indicator 100A prevents displacement not only in the longitudinal direction but also in the width direction, thereby realizing a more stable wearing state and reducing stress during diaper changing.

Further, the absorbent body 2 of this embodiment extends along the longitudinal direction over the first waist portion 1A, the crotch portion 1C, and the second waist portion 1B, and the mounting index 100A is in the width direction. It is located outside the absorber 2.

When aligning the mounting index 100A with the area X between the iliac crest Pa and the acetabulum Q of a low birth weight infant (FIG. 4), if the mounting index 100A is provided at a position overlapping the absorber 2 in the width direction, At the time of wearing, the wearing indicator 100A may become difficult to see due to the body of the wearer (low birth weight child). However, by arranging it outside the absorber 2 in the width direction, the visibility from the skin side of the diaper 1 when worn is improved.

In addition, at the time of wearing, the unfolded diaper 1 shown in FIG. Assuming that the crotch 1C is on the lower side, the mounting index 100A is provided between the lower end 40ed of the fastening tape 40 and the center (center position ML) in the vertical direction. By adjusting to the attachment index 100A, the part between the iliac crest Pa and the acetabulum Q of a low birth weight infant (the area marked by The portion of the fastening tape 40 does not obstruct the movement of the low birth weight baby during the process and wearing of the diaper. Thereby, a stable wearing state can be maintained.

In addition, the fastening tape 40 of the present embodiment is fixed to each outer end in the width direction, and hook materials 42 are provided on the skin side of the fastening tape 40. In some cases, an engaging part (hook material) is provided at the part so that the fastening tape 40 can be removed from either the ventral side or the dorsal side of the diaper 1. In that case, for example, when reattaching the fastening tape 40 while the diaper 1 is in use, the attachment index 100A may be used as a positioning guide for reattachment. That is, the attachment indicator 100A may overlap the fastening tape 40 in the longitudinal direction. By locking the fastening tape 40 at the position of the mounting index 100A in the longitudinal direction, the stable mounting state can be prevented from shifting.

FIG. 6 is a diagram showing a modification of the attachment indicator 100 (100A). The mounting index 100A shown in FIG. 6 (the part indicated by diagonal lines downward to the left) is provided in the entire area from the lower end 40ed of the fastening tape 40 to the center ML of the diaper 1 in the vertical direction. For example, if only one small indicator is provided as the attachment indicator 100A, the indicator should be in contact with the area X (Fig. 4) between the iliac crest Pa and the acetabulum Q of a low birth weight infant. Even if you insert the diaper with aim, there is a risk that it will shift within that area. However, since the attachment index 100A exists in the entire area from the lower end 40ed of the fastening tape 40 to the center ML in the vertical direction, it becomes easier to see the area for positioning, and it becomes easier to insert the diaper in a more appropriate position. can.

Furthermore, the mounting indicator 100A in the modification shown in FIG. 6 may be provided together with the mounting indicator 100A in the present embodiment shown in FIG. In that case, using the attachment index 100A (FIG. 1) of the present embodiment, it is possible to know where on the diaper 1 the portion between the iliac crest Pa and the acetabulum Q of the low birth weight infant should be brought into contact. It is possible to easily check the degree of insertion of the diaper 1 by using the modified attachment indicator 100A (FIG. 6), which is provided long in the vertical direction, as a guide.

Returning to FIGS. 1 and 2A, in this embodiment, the top sheet 3 is located closer to the skin in the thickness direction than the absorbent body 2, and the pair of side sheets 20 are arranged on the skin side of the top sheet 3. They are arranged in pairs in the direction. The attachment indicator 100A of this embodiment is provided on the skin side of the backsheet 4. By providing it on the skin side of the back sheet 4, the attachment indicator 100A can be seen through the skin side through the top sheet 3 and side sheet 20. With this configuration, the mounting index 100A can be created at the same time during the printing process of the backsheet 4, so that it is possible to reduce the cost of the manufacturing process.

<<When wearing the diaper backwards>>
Next, a case will be described in which the diaper 1 is made to be worn by a low birth weight baby who is taking a positioning posture, which is a posture unique to low birth weight babies. FIG. 7 is a schematic plan view of the disposable diaper 1 in an expanded and stretched state, viewed from the non-skin side in the thickness direction. FIG. 8 is a diagram showing the diaper 1 in a folded state at the folding position Fd. FIG. 9A is a diagram showing a state in which the diaper 1 is inserted into the ventral side of a low birth weight infant who is in a positioning posture, and FIG. 9B is a diagram showing a state in which the diaper 1 is inserted into the abdomen of a low birth weight infant who is in a positioning posture. It is a figure showing the state where it is worn.

When placing Diaper 1 on a low birth weight infant who is in a positioning position, based on the concept of minimal handling, which states that it is desirable to avoid touching the body of the low birth weight infant as much as possible, the infant should be placed in a prone position rather than on the back. It is preferable to wear it as is. Therefore, when the diaper 1 is worn normally from front to back, it is necessary to put a hand under the abdomen of a low-weight baby in a prone position to lock and remove the fastening tape 40, which is not easy to operate.

Furthermore, low birth weight infants are generally often raised in incubators at hospitals and the like. Therefore, when putting a diaper on a low birth weight baby, the operator (the person changing the diaper) must pass his or her hand through a working window provided in the incubator and work within a narrow space. For example, when putting on a diaper for a low birth weight infant who is in a positioning position in an incubator, the worker must pass the diaper between the infant's legs with one hand and pull it out toward the abdomen with the other hand. is required, which limits operability.

On the other hand, in the diaper 1 of this embodiment, as shown in FIGS. 9A and 9B, the diaper 1 is worn with the front and rear sides reversed so that the first waist portion 1A covers the abdominal side (hereinafter referred to as "front and back reversed"). By having a low birth weight baby wear a baby's clothes (also called ``wearing''), work can be done without putting stress on the body of a low birth weight baby. Hereinafter, the operation when the diaper 1 is worn backwards and forwards on a low birth weight baby will be explained.

When the diaper 1 is worn backwards and forwards on a low weight baby who is in a positioning posture, the first waist portion 1A of the diaper 1 is first applied to the ventral side of the low weight baby. As shown in FIG. 7, the diaper 1 has a pair of folding positions Fd along the longitudinal direction on both sides in the width direction in at least a portion of the first waist portion 1A and the crotch portion 1C. When inserting the diaper 1 into the ventral side of a low birth weight baby, first, the pair of side flaps 20 (front side extension part 20A and fastening tape 40) are each folded inward in the width direction at the pair of folding positions Fd (Fig. 8). By doing this, the widthwise dimension of the diaper 1 on the side to be inserted is made as small as possible, and the first waist portion 1A is inserted so as to pass between the wearer's legs from the crotch side to the ventral side ( Figure 9A). Further, the second waist portion 1B is applied to the back side of the low birth weight infant (FIG. 9B).

After the first girth part 1A is applied to the abdomen of the low birth weight baby, the folded front side extension part 20A and the fastening tape 40 are pulled out from under the belly of the low birth weight baby to both sides in the width direction. expand. Then, the unfolded front side extension part 20A and the fastening tape 40 are passed around the waist of the low birth weight infant from the ventral side to the back side, and the fastening tape is applied to the target area 45 of the second waist part 1B located on the back. 40 (hook material 42) is engaged. By performing these operations, the diaper 1 can be worn backwards and forwards as shown in FIG. 9B.

In this way, when the diaper 1 is worn backwards and forwards, it is difficult to determine which position on the abdomen of a low birth weight baby who is in the positioning position to insert the diaper 1 properly. It may be difficult. Therefore, in the diaper 1 of this embodiment, the area where the diaper 1 is folded toward the skin side at the pair of folding positions Fd shown in FIG. 7 is defined as a folding area 80 (see FIG. 8), and the diaper 1 is A mounting indicator 100 (hereinafter referred to as "mounting indicator 100B") that is visible when viewed in the thickness direction is provided. The attachment index 100B is located between the lower end of the wearer's acetabulum (Q in FIG. 4) in the longitudinal direction of the folding region 80 when the wearer (low birth weight infant) is in the prone position or positioning posture. This is a mark when pulling the diaper 1 toward the wearer's ventral side using the lower end of the ischial bone (R in FIG. 4) as an index. Specifically, as shown in FIG. 9, the attachment index 100B comes to the region Y shown in FIG. 4 between the lower end of the acetabulum (Q) and the lower end of the ischial bone (R) of the low birth weight infant. By inserting the diaper 1 and then unfolding and wearing it, the diaper 1 can be inserted into the body of a low birth weight baby appropriately. As a result, a stable wearing condition is achieved, and stress on users such as nurses when changing diapers is reduced. In addition, by stably wearing the device, parents and others watching over the device can easily feel the feeling of wearing clothes.

Note that although a heart-shaped indicator is used as an example of the attachment indicator 100B shown in FIG. 7, the attachment indicator 100B is not limited to this, and any indicator that is easily visible to the person changing the diaper 1 can be used.

Further, as shown in FIG. 7, a pair of attachment indicators 100B are provided on both sides of the diaper 1 in the width direction, and are arranged symmetrically with respect to the center in the width direction (center position CL1). The center CL1 in the width direction of the diaper 1 is a position corresponding to the center of the body of a low birth weight infant who is the wearer, and a pair of attachment indicators 100B are placed on both sides in the width direction, and a position is symmetrical with respect to the center CL1. By doing so, it is possible to confirm the deviation in the width direction from the center of the body of a low birth weight infant. In addition, the wearing indicator 100B prevents displacement not only in the longitudinal direction but also in the width direction, thereby realizing a more stable wearing state and reducing stress during diaper changing.

Furthermore, the mounting index 100B is located outside the absorbent body 2 in the width direction. Being located on the outer side of the absorber 2 in the width direction improves the visibility of the wearing indicator 100B in the folding region 80 when the diaper 1 is folded toward the skin side along the folding position Fd from the unfolded state shown in FIG.

Furthermore, when the diaper 1 is applied to the body of a low birth weight baby, the diaper 1 in the unfolded state shown in FIG. Assuming that the two waist openings are on the upper side and the crotch area is on the lower side, the mounting index 100B is provided between the center ML and the lower end (corresponding to the center position CL2) of the diaper 1 in the vertical direction. By aligning with the attachment index 100B, the part between the lower end of the acetabulum (Q) and the lower end of the ischial bone (R) of a low birth weight infant in the positioning posture (Y area in Fig. 4) can be adjusted in the vertical direction. In this case, the first extension part 20A, which is aligned between the center ML and the lower end (CL2) and to which the fastening tape 40 is fixed, does not hinder the movement of the wearer during the wearing process and is stable. You can keep it attached.

FIG. 10 is a diagram showing a modification of the mounting index 100 (100B). The attachment indicator 100B (the part indicated by diagonal lines downward to the left) shown in FIG. 10 is provided in the entire area from the center ML to the lower end (CL2) of the diaper when folded in half in the vertical direction. For example, if only one small indicator is provided as the attachment indicator 100B, it may be located between the lower end of the acetabulum (Q) and the lower end of the ischial bone (R) of a low birth weight infant (Y area in Fig. 4). Even if you insert the diaper 1 with the aim of making it move, there is a risk that it will shift within that area. However, since the attachment index 100B exists in the entire area from the center ML to the lower end (CL2) in the vertical direction, it becomes easier to understand the area where alignment is performed with the body of a low birth weight infant in the positioning posture, and more appropriate You can insert the diaper into position.

Further, the mounting indicator 100B in the modification shown in FIG. 10 may be provided together with the mounting indicator 100B of the present embodiment shown in FIG. 7 and the like. In that case, according to the attachment index 100B (FIG. 7) of the present embodiment, the part between the lower end of the acetabulum (Q) and the lower end of the ischial bone (R) of the low birth weight baby can be specifically positioned at which position in the diaper 1. While making it easy to understand whether the diaper 1 is in contact with the diaper 1, it is possible to easily check the degree of insertion of the diaper 1 by using the modified attachment indicator 100B (FIG. 10), which is provided long in the vertical direction, as a guide.

<<About the central attachment index>>
Moreover, as shown in FIG. 7, the diaper 1 of this embodiment is provided with a central wearing indicator 110, which is different from the fitting indicator 100 (100B), at the center in the longitudinal direction. Further, the central wearing indicator 110 is visible from the non-skin side of the diaper 1, similarly to the wearing indicator 100B.

FIG. 11 is a diagram showing a state in which the diaper 1 is pulled up when the diaper 1 is worn. When wearing the diaper 1, the central part in the longitudinal direction corresponds to the acetabulum (Q in FIG. 4) in the crotch of a low birth weight baby, and as shown in FIG. When the diaper 1 is pulled up so that it is located between the left and right acetabulum, the diaper is properly inserted. This makes it easier to achieve a stable wearing state, and reduces stress on the user (nurse, etc.) of the diaper 1 when changing the diaper. In addition, stable wearing makes it easier to feel like clothes.

Further, as shown in FIG. 7, a pair of central attachment indicators 110 are provided on both sides of the diaper 1 in the width direction, and are arranged symmetrically with respect to the center in the width direction (center position CL1). The center CL1 in the width direction of the diaper 1 is a position corresponding to the center of the body of a low birth weight infant who is the wearer. It is possible to check the deviation in the width direction from the center of the baby's body, realizing a more stable wearing condition. Further, as shown in FIG. 9B, when putting the diaper 1 on a low birth weight baby who is in a positioning posture, if the baby's legs are bent so that the heels of the low birth weight baby are positioned on the pair of central attachment indicators 110, the appropriate This makes it easier to position yourself. Therefore, the central attachment index 110 also serves as a guide for the position of the feet in the positioning posture.

Moreover, the central attachment indicator 110 of this embodiment overlaps with the absorber 2 in the width direction. The crotch area 1C is a part where wrinkles tend to form as it is pinched between the wearer's legs when worn, but wrinkles are less likely to occur in the absorbent core 2 part because the product has tension due to the thickness of the absorbent core 2. By arranging the central attachment indicator 110 so as to overlap the absorber 2 in the width direction, the person changing the diaper 1 can easily visually recognize the central attachment indicator 110. In addition, although the central attachment index 110 of this embodiment is provided so as to overlap with the absorbent body 2 in the width direction, the present invention is not limited to this, and at least a part of the central attachment index 110 is provided so as to overlap the absorbent body 2 in the width direction. It is sufficient if it overlaps with

Moreover, although a flower-patterned indicator is used as an example for the central attachment indicator 110 shown in FIG. 7, the indicator is not limited to this in any way, and any indicator that is easily visible to the person changing the diaper 1 may be used.

FIG. 12 is a schematic plan view of the disposable diaper 1 provided with the pattern 120 in an unfolded and stretched state, viewed from the non-skin side in the thickness direction. The pattern 120 is an example of a decorative pattern that decorates the diaper 1. The pattern 120 is provided on the non-skin side of the backsheet 4 by printing or the like, and is visible from the non-skin side of the diaper 1. In this embodiment, among the patterns 120, a heart-shaped pattern is a pattern 120a, and a flower pattern is a pattern 120b. The attachment indicator 100B has a similar shape to the pattern 120a, and the central attachment indicator 110 has a similar shape to the pattern 120b. In this embodiment, both the attachment indicator 100B and the central attachment indicator 110 have a similar shape to the pattern 120 (120a or 120b) of the diaper 1, but they may also have the same shape with the same size.

After putting the diaper 1 on a low birth weight baby who is in a positioning posture, the low birth weight baby may be changed from a prone position to a supine position. The attachment indicators 100B and the center attachment indicators 110 provided on the sides (sides) are visible to the nurses and parents watching over them. Since the mounting index 100B and the central mounting index 110 have the same shape or similar shape to the pattern 120 (120a, 120b) of the diaper 1, each mounting index (100B, 110) is not used as an index but as a part of the pattern of the diaper 1. become more easily recognized as part of the Further, such a configuration does not interfere with the worldview of the overall design of the diaper 1, and can give it an even more clothes-like feel.

<<About colored areas>>
FIG. 13 is a schematic plan view of the disposable diaper 1 having the colored region 150 in an expanded and stretched state, viewed from the non-skin side in the thickness direction. FIG. 14 is a diagram showing the colored area 150 when the diaper 1 is pulled up when the diaper 1 is worn. In FIG. 13, for convenience of explanation, the attachment indicator 100B and the central attachment indicator 110 are omitted.

The diaper 1 shown in FIG. 13 has a colored region 150 that is colored in a predetermined color from both ends of the backsheet 4 to the outer edge region of the absorbent core 2A in the width direction and is visible from the non-skin side of the diaper 1. have. Note that the term "end" as used herein refers to a range up to 10 mm from the end of the backsheet 4 in the width direction to the inner side in the width direction. The "outer edge region" of the absorbent core 2A refers to a range up to 10 mm from the widthwise end (outer edge) of the absorbent core 2A to the inner and outer sides in the width direction. Further, a pair of colored regions 150 are provided on both sides of the diaper 1 in the width direction along the longitudinal direction. In this embodiment, the colored area 150 is printed on the backsheet 4. Then, as shown in FIG. 14, when applying the diaper 1 to a low-weight baby in a supine position and pulling up the diaper 1, by using the colored area 150 as a guide, the center of the low-weight baby's crotch and the width of the diaper 1 can be adjusted. It becomes easier to align the center of the direction. Further, the absorbent core 2A is a highly rigid part of the diaper 1, but since the colored region 150 is provided outside the absorbent core 2A in the width direction, the rigid part (absorbent core 2A) The boundary between the non-rigid parts (the outside of the absorbent core 2A) can be easily seen, and the rigid parts can be prevented from hitting the leg area. Therefore, it is easy to wear the device so as not to hinder the positioning and body movements of low birth weight infants.

In addition, in the unfolded state shown in FIG. 13, the total length L1 in the longitudinal direction of the diaper 1 is defined as the center position ML in the vertical direction on the first waist part 1A side, the center position CL2 in the longitudinal direction of the diaper 1, and the second waist part 1A. Of the four areas divided into four equal parts at the center position NL in the vertical direction on the 1B side, the two areas located on the inside in the longitudinal direction (that is, the area from ML to NL in the longitudinal direction) are called the inner area CH. Then, the colored regions 150 are each provided in the inner region CH in the longitudinal direction. In the two regions that are the inner region CH, at least one of the colored regions is a region that can be visually recognized regardless of whether the low birth weight infant is in the supine or prone position. By providing the colored area 150 in the two areas that are the inner area CH, when worn, the rigid part (absorbent core 2A) and the non-rigid part (outside of the absorbent core 2A) can be seen in both the supine and prone positions. ) becomes easier to understand. By preventing the rigid part from touching the child's legs, it becomes easier to wear the device without interfering with the positioning and body movements of low birth weight infants.

Further, as shown in FIG. 13, the colored region 150 has a convex shape in which an inner edge 150 inches in the width direction protrudes toward the inner side in the width direction at the center portion in the longitudinal direction of the diaper 1. The central part of the diaper 1 in the longitudinal direction is the crotch part 1C, and this part is a part where the length (width) in the width direction becomes narrow because it is sandwiched between the legs of a low birth weight baby when the diaper is worn. By making the colored region 150 protrude inward in the width direction so as to follow such a narrowing shape of the diaper 1, it gives the impression that the diaper 1 is being worn in a better fit to the body, giving the diaper 1 an even more clothes-like feel. be able to.

Further, the predetermined colors of the colored area 150 are 196U, 217U, 250U, 496U, 502U, 503U, 510U, 517U, 670U, 671U, 677U, 678U, 684U, 685U, The color corresponds to any one of 691U, 692U, 698U, 699U, 705U, 706U, 7422U, 7429U, 7430U, and 7436U. These colors in the PANTONE® color swatch book are visually perceived as pale pink.

The determination as to whether the color is a predetermined color shown in the PANTONE (registered trademark) color sample book is performed, for example, by a method similar to the method disclosed in Japanese Patent No. 5934744. That is, this is done by comparing the visually observed color of the colored region 150 with the color sample book.
