Description

The present invention relates to a deployable disposable diaper for low weight infants weighing 3000 grams or less.

Conventionally, deployable disposable diapers have been known. The deployable disposable diaper is configured so that it can fully exert its functions such as absorption of excrement fluid and suppression of leakage by being worn at an appropriate position of the wearer. For example, Patent Document 1 discloses an absorbent article having a mark portion for attaching a diaper at an appropriate position of a wearer, and the mark portion has an order display portion indicating an order of wearing operations. Has been done.

Some of these deployable diapers have infants as the wearer. For example, if the wearer is a baby in the NICU who gave birth with a low weight of 3000 grams or less (low weight baby), the low weight baby stays in the womb while being surrounded by medical equipment in an incubator. In many cases, the baby is in a prone posture (positioning posture) in which both legs are bent with the abdomen facing down and the knees are attracted to the abdomen. In addition, depending on the low weight child, the concept of minimum handling, in which it is desirable not to touch the body, may be applied from the viewpoint of not giving extra stress. In that case, the diaper is worn in the above-mentioned positioning posture.

When a low weight infant in a positioning position wears a deployable diaper, it is difficult to lock the fastening tape on the abdominal side hidden between the legs. Therefore, there is a method of putting on the diaper by turning the front and back of the diaper upside down and locking the fastening tape on the back side of the low weight child. In this case, the diaper is applied to the ventral side of the low weight infant by turning it upside down, but it may be difficult to determine to what position the diaper should be inserted into the ventral side with respect to the body to obtain stable wearing. is there.

In addition, even when wearing a diaper on a low-weight baby lying on his back, in a special environment where the body is connected to a medical device in an incubator, simply indicating the order of wearing the diaper as in Patent Document 1 is sufficient. , It may be difficult to achieve an appropriate wearing condition for the baby's body. Incomplete wearing of the diaper not only does not fit the diaper to the body, but also wrinkles the design design on the exterior of the diaper, impairing the original design. , There is a risk that the feeling of clothes in the diaper will fade and the feeling of goods will increase.

The present invention has been made in view of the above-mentioned conventional problems, and an object of the present invention is to realize a stable wearing state in a deployable disposable diaper for a low weight child of 3000 grams or less. is there.

The unfolded state of the diaper 1 is a state in which the diaper 1 is unfolded on a plane by opening the diaper 1 in the longitudinal direction thereof. Further, the extended state of the diaper 1 is a state in which the diaper 1 is extended to the extent that the wrinkles formed on the diaper 1 are substantially invisible in the unfolded state of the diaper 1, and each member constituting the diaper 1 is formed. The diaper 1 is in a stretched state until the dimensions of the member (for example, the side sheet 6 described later) match or are close to the dimensions of the member alone.

<< 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 orthogonal to each other, and from one side in the longitudinal direction, a first waist circumference portion 1A, a crotch lower portion 1C, and a second. It has a waist circumference portion 1B side by side. Further, 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 in contact with the wearer is called the "skin side", and the opposite side is called the "non-skin side".

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

The top sheet 3 can be an air-through non-woven fabric or the like, the leak-proof sheet 4 can be a resin film such as a polyethylene film, and the exterior sheet 5 and the side sheet 6 can be an SMS non-woven fabric (spun bond / melt blown). / Spunbond non-woven fabric) and other flexible sheets can be exemplified.

As shown in FIG. 1, the absorber 2 has a substantially rectangular shape in a plan view and is provided at the center in the width direction. The absorber 2 has 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 in a plan view, and has a constricted portion 2c between one end 2ga and the other end 2gb in the longitudinal direction. The width direction of the constricted portion 2c is smaller than the width direction of the one end portion 2ga and the other end portion 2gb. Further, the absorbent core 2A has notches (notches 71, 72, 73, which will be described later). Examples of the liquid-absorbent material include those in which a liquid-absorbent fiber such as pulp fiber contains a highly absorbent polymer (so-called SAP). Examples of the core wrap sheet 2B include liquid-permeable tissue paper and non-woven fabric, but the absorber 2 may not have the core wrap sheet 2B.

Side flaps 20 are provided on both sides of the absorber 2 in the width direction. As shown in FIG. 2A, the side flap 20 is composed of a side sheet 6 and a part of the exterior sheet 5. The side flaps 20 are a pair of first extending portions 20A extending outward in the width direction from the inseam 1C in the first waist circumference 1A, and both in the width direction from the inseam 1C in the second waist circumference 1B. It is provided with a pair of second extending portions 20B extending outward. Further, fastening tapes 40 are fixed to each end of the pair of first extending portions 20A on the outer side in the width direction.

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

The fastening tape 40 can be engaged with the target region 45 (see FIG. 1), which is a predetermined region provided on the non-skin side of the exterior sheet 5 in the second waist circumference portion 1B. In the present embodiment, the exterior sheet 5 is made of non-woven fabric so that the hook material 42 can be directly locked to the exterior sheet 5 (target region 45). However, the present invention is not limited to this, and a member such as a female member of the hook-and-loop fastener in which the hook member 42 is easily locked may be provided separately from the exterior sheet 5. Further, instead of the hook material 42, for example, an 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 the substantially central position CL2 (see FIG. 1) in the longitudinal direction, and a pair on the first waist circumference 1A side. The first extending portion 20A of the above is folded back inward in the width direction. Then, each hook member 42 provided on the pair of fastening tapes 40 is locked to the target region 45 provided on the non-skin side surface of the second waist circumference portion 1B. As a result, the waist opening and the 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).

Further, the diaper 1 has a pair of three-dimensional gathered portions 50 as leak-proof walls at positions on both side portions in the width direction. As shown in FIG. 3, each three-dimensional gather portion 50 is located at both ends in the longitudinal direction and in the thickness direction with an elastic member 51 (for example, rubber thread) for the three-dimensional gather portion 50 that can be expanded and contracted in the longitudinal direction. A pair of first base end portions 52 that cannot stand up, and outside of the first base end portion 52 in the width direction, are located over the entire length direction of the diaper 1 and cannot stand up in the thickness direction. It has a second base end portion 53 and an upright 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 form an elongated rectangular shape in the longitudinal direction, and are formed by fixing the side sheet 6 to the top sheet 3. As the fixing method, for example, a well-known method such as adhesion or welding with a hot melt adhesive can be exemplified. In FIG. 3, two first base end portions 52 are arranged in the width direction at each end portion in the longitudinal direction of each three-dimensional gather portion 50, 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 the side sheet 6 having two layers is used for the three-dimensional gather portion 50. The elastic member 51 is fixed in an extended 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, is in the thickness direction with the second base end portion 53 as a fulcrum due to the contraction of the elastic member 51. Stand up on the skin side of. In FIG. 3, the number of elastic members 51 included in each three-dimensional gather portion 50 is one, but the number is not limited to this, and a plurality of elastic members 51 may be arranged in the width direction.

Further, a pair of elastic members 7 around the legs (for example, rubber threads) that are both sides in the width direction of the diaper 1 and can be expanded and contracted in the longitudinal direction mainly at the position of the inseam 1C so as to follow the legs of the wearer. Is provided. The leg circumference elastic member 7 is fixed to the non-skin side surface of the side seat 6 in a 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 FIG. 1, two leg-surrounding elastic members 7 are arranged in the width direction on each side of the diaper 1 in the width direction, but the number is not limited to two.

In the above, the elastic member 51 for the three-dimensional gather portion 50 and the leg circumference elastic member 7 exemplify the thread rubber, but the present invention is not limited to this. These elastic members 51 and 7 may be, for example, an elastic non-woven fabric made of a thread-like polyurethane elastic fiber, an elastic film formed by melting a thermoplastic elastomer resin into a film, or an elastic fiber.

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

The cut line 60 is used especially when removing the diaper 1 from a low weight child. That is, there is an idea that it is desirable for a low-weight infant who gave birth with a low weight of 3000 grams or less (particularly less than 2500 grams) to spend time in a prone position while in the womb. The posture when in the womb is a state in which the back is curled up in a C shape with the abdomen facing down, and both legs are bent in an M shape while both knees are attracted to the abdomen. .. Hereinafter, such a posture peculiar to a low weight child is also referred to as a “positioning posture” (see FIG. 9B described later).

For example, when a diaper is worn upside down for a low-weight child in a positioning posture (see "front-back reverse wearing" described later, FIG. 9B), the fastening tape 40 is locked on the back side of the wearer. By cutting the cutting line 60, the diaper 1 expands in the longitudinal direction with the fastening tape 40 locked to the second waist circumference portion 1B located on the dorsal side. Therefore, the diaper 1 can be pulled out without passing the first waist circumference 1A (here, the ventral side) to which the hard fastening tape 40 is fixed between the legs of the low weight child, and the skin of the low weight child can be pulled out. The burden can be reduced.

Further, the absorber 2 (absorbent core 2A) shown in FIG. 1 is provided with a pair of notches 71 at the central portion 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 central portion and the one end portion 2ga in the longitudinal direction, and the width direction is provided between the central portion and the other end portion 2gb in the longitudinal direction. A pair of notches 73 are provided at both ends of the above. The number of notches does not have to be provided in three pairs (71, 72, 73) as in the present embodiment, and may be any number. Each notch (71, 72, 73) has both ends in the width direction of the absorber 2 formed in a chevron shape toward the inside in the width direction, but the shape is limited to the shape shown in FIG. Absent. Further, in the present embodiment, the absorber 2 (absorbent core 2A) is notched in each cutout portion (71, 72, 73), but the liquid absorbent material is more than the other portion of the absorber 2. It may be formed by reducing the basis weight. Each pair of notches (71, 72, 73) can prevent the absorbent core 2A from twisting and a gap between the diaper 1 and the wearer, and can suppress the leakage of excrement.

<< When wearing normal diapers before and after >>
When a low weight child in a supine position wears a deployable diaper, it is usually worn with the low weight child lying on his back after the diaper is spread out in the longitudinal direction. At that time, the first waist circumference portion 1A to which the fastening tape 40 is fixed covers the dorsal side, and the second waist circumference portion 1B is worn so as to cover the ventral side. Here, the case where the first waist circumference portion 1A is worn so as to cover the back side as usual is referred to as "front and back normal wear".

On the other hand, low-weight infants in the NICU, etc. often have their bodies connected to medical devices in the incubator, and even when wearing them normally before and after, in such an environment, the body of the low-weight infant will be affected. On the other hand, it may be difficult to realize an appropriate mounting state. If the diaper is incompletely attached, the diaper will not fit the body and there is a possibility of leakage, and the diaper's clothes may be weakened and the feeling of goods may be increased. .. Incubators often do not wear clothing other than diapers, so for parents of low-weight children watching from outside the incubator, underwear is more than what looks like a medical item due to unstable wearing. It is easy to get a sense of security if it looks like.

On the other hand, in the diaper 1 of the present embodiment, a wearing index 100 that can be visually recognized by a diaper 1 changer (nurse or the like) at the time of wearing is provided (see FIG. 1 and FIG. 7 described later). The wearing index 100 serves as a guide for how much the diaper 1 should be inserted when the diaper 1 is inserted under the body of the low-weight child, and at what position on the body of the low-weight child.

The wearing index 100 in FIG. 1 is a wearing index 100 (hereinafter referred to as “wearing index 100A”) that can be visually recognized from the skin side of the diaper 1 by a diaper 1 changer (nurse or the like). It is provided in the first waist circumference portion 1A. The wearing index 100A is an index that serves as a guide when the front and rear are normally worn, and the first waist circumference 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 a low weight child in a supine position is made to wear the diaper 1. The structure of the human pelvis in FIG. 4 here means the structure of the pelvis of the wearer, a low weight infant. The wearing index 100A shown in FIG. 1 uses the iliac crest Pa and the acetabulum Q of the iliac bone P of the low-weight infant shown in FIG. 4 as indexes in the longitudinal direction of the diaper 1 to reduce the weight of the diaper 1. It serves as a mark when pulling into the back of the child. Specifically, as shown in FIG. 5, when the diaper 1 is worn on a low weight child in the supine position, the wearing index 100A can be visually recognized from both sides of the abdomen of the low weight child. The diaper changer inserts the diaper 1 under the body of the child, and while visually recognizing the wearing index 100A, the wearing index 100A is between the iliac crest Pa and the acetabulum Q of the child shown in FIG. The diaper 1 is pulled in so as to come into contact with the area of X, and is attached to the child. The iliac crest Pa is the outermost protruding portion of the iliac bone P, and the protruding portion is a portion that is easy to understand when the hip is touched. The acetabulum Q is a cup-shaped recess that serves as a saucer for the femoral head, and forms a hip joint together with the femoral head.

By mounting the diaper 100A so as to abut between the iliac crest Pa and the acetabulum Q of the low weight infant, the degree of insertion of the diaper 1 into the infant's body becomes appropriate. As a result, it becomes easy to realize a stable wearing state, and it is possible to reduce stress when changing diapers by a wearer such as a nurse. In addition, stable wearing makes it easier for parents who are watching over to feel the feeling of clothes.

The wearing index 100A shown in FIG. 1 uses a triangular index as an example, but the index is not limited to this, and an index having an arbitrary shape that is easily visible to the diaper 1 changer can be used.

Further, as shown in FIG. 1, a pair of wearing indexes 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 weight child who is the wearer, and the wearing index 100A is a pair on both sides in the width direction and a position symmetrical with respect to the center CL1. Therefore, it is possible to confirm the deviation in the width direction with respect to the center of the body of the low weight infant. In addition, the wearing index 100A prevents deviations not only in the longitudinal direction but also in the width direction, thereby realizing a more stable wearing state and reducing stress when changing diapers.

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

When the attachment index 100A is aligned with the region X (FIG. 4) between the iliac crest Pa and the acetabulum Q of a low weight infant, if the attachment index 100A is provided at a position overlapping the absorber 2 in the width direction, the attachment index 100A is provided. When worn, the wearing index 100A may be difficult to see depending on the body of the wearer (low weight child). However, by arranging the diaper outside the absorber 2 in the width direction, the visibility of the diaper 1 from the skin side is improved when the diaper 1 is worn.

Further, at the time of wearing, the unfolded diaper 1 shown in FIG. 1 is folded in half at the central portion (center position CL2) in the longitudinal direction, and one waist circumference opening when applying the diaper 1 to the body of a low-weight child is on the upper side. When the inseam 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 in the vertical direction. By adjusting to the wearing index 100A, the portion between the iliac crest Pa and the acetabulum Q (the region X in FIG. 4) of the low weight infant is the lower end 40ed of the fastening tape 40 and the central ML in the vertical direction. Aligned with, the portion of the fastening tape 40 does not impede the movement of the low weight infant during and during the diaper wearing process. As a result, a stable wearing state can be maintained.

Further, the fastening tape 40 of the present embodiment is fixed to each end on the outer side in the width direction, and hook members 42 are provided on the skin side surface of the fastening tape 40. For example, both ends of the fastening tape 40 in the width direction are provided. In some cases, an engaging portion (hook material) is provided in the portion 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 the fastening tape 40 is reattached while the diaper 1 is in use, the attachment index 100A may be used as a guideline for alignment for reattaching. That is, the mounting index 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, it is possible to prevent the stable mounting state from shifting.

FIG. 6 is a diagram showing a modified example of the mounting index 100 (100A). The mounting index 100A (the portion indicated by the diagonal line downward to the left) shown in FIG. 6 is provided in the entire area from the lower end 40ed of the fastening tape 40 to the central ML of the diaper 1 in the vertical direction. As the wearing index 100A, for example, when only one small index is provided, the index abuts on the region X (FIG. 4) between the iliac crest Pa and the acetabulum Q of the low weight infant. Even if the diaper is aimed at and inserted, there is a risk that it will shift within that area. However, in the vertical direction, the presence of the mounting index 100A in the entire area from the lower end 40ed of the fastening tape 40 to the central ML makes it easier to understand the region to be aligned, and the diaper can be inserted at a more appropriate position. it can.

Further, the mounting index 100A in the modified example shown in FIG. 6 may be provided together with the mounting index 100A of the present embodiment shown in FIG. In that case, from the wearing index 100A (FIG. 1) of the present embodiment, it is possible to know which position of the diaper 1 the portion between the iliac crest Pa and the acetabulum Q of the low weight infant is specifically brought into contact with. While making it easy, it is possible to easily confirm the degree of insertion of the diaper 1 by using the mounting index 100A (FIG. 6) of the modified example provided long in the vertical direction as a guide.

Returning to FIGS. 1 and 2A, in the present embodiment, the top sheet 3 is located on the skin side in the thickness direction of the absorber 2, and the pair of side sheets 20 are wide on the skin side surface of the top sheet 3. A pair are provided side by side in the direction. The wearing index 100A of the present embodiment is provided on the skin side surface of the back seat 4. By providing the back seat 4 on the skin side surface, the wearing index 100A can be seen through the skin side through the top sheet 3 and the side seat 20. With such a configuration, the mounting index 100A can be created at the same time in the printing process of the back sheet 4, so that the cost of the manufacturing process can be reduced.

<< When wearing diapers upside down >>
Next, a case where a low-weight child in a positioning posture, which is a posture peculiar to a low-weight child, is made to wear the diaper 1 will be described. FIG. 7 is a schematic plan view of the unfolded and stretched disposable diaper 1 as viewed from the non-skin side in the thickness direction. FIG. 8 is a diagram showing a 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 the low weight child in the positioning posture, and FIG. 9B is a diagram showing the front and back of the diaper 1 in the low weight child in the positioning posture. It is a figure which shows the state which was put on.

When a low-weight child in a positioning position wears diaper 1, it is desirable to avoid touching the body of the low-weight child as much as possible. Therefore, the low-weight child should not lie on his back and should be in a prone position. It is desirable to wear it as it is. Therefore, when the diaper 1 is normally worn in the front and back, it is necessary to put a hand under the abdomen of a low weight infant in a prone position to lock or remove the fastening tape 40, which is not good in operability.

In addition, low-weight infants are generally raised in incubators at hospitals and the like. Therefore, when making a low-weight child wear a diaper, it is necessary for a worker (diaper changer) to work in a narrow space through a work window provided in an incubator. For example, when wearing a diaper for a low weight child in a positioning position in an incubator, the worker puts the diaper between the legs of the low weight child with one hand and pulls it out to the ventral side with the other hand. Is required, and operability is limited.

On the other hand, in the diaper 1 of the present embodiment, as shown in FIGS. 9A and 9B, the front and back of the diaper 1 are reversed, and the first waist circumference portion 1A is worn so as to cover the ventral side (hereinafter, "back and forth reverse"). By making them wear (also called "wearing"), the work can be performed without burdening the body of a low-weight child. Hereinafter, the operation when the diaper 1 is worn upside down for a low weight child will be described.

When a low-weight child in a positioning posture is to wear the diaper 1 upside down, first, the first waist circumference 1A of the diaper 1 is applied to the ventral side of the low-weight child. 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 at least a part of the first waist circumference portion 1A and the inseam 1C. Then, when the diaper 1 is inserted into the ventral side of the low weight infant, first, the pair of side flaps 20 (front extending portion 20A and fastening tape 40) are folded inward in the width direction at the pair of folding positions Fd (FIG. 8). By doing so, the dimension in the width direction of the diaper 1 on the insertion side is made as small as possible, and the first waist circumference portion 1A is inserted so that the space between the wearer's legs is passed from the inseam side to the ventral side ( FIG. 9A). Further, the second waist circumference portion 1B is applied to the dorsal side of the low weight child (FIG. 9B).

After the first waist circumference 1A is applied to the abdomen of the low weight child, the folded front extension part 20A and the fastening tape 40 are pulled out from under the abdomen of the low weight child to both sides in the width direction. expand. Then, the deployed front extension portion 20A and the fastening tape 40 are turned from the ventral side to the dorsal side along the waist circumference of the low weight child, and the fastening tape is provided in the target area 45 of the second waist circumference portion 1B arranged on the back side. 40 (hook material 42) is engaged. By performing these operations, the diaper 1 can be worn upside down as shown in FIG. 9B.

In this way, when the diaper 1 is worn upside down, it is clear from conventional general diapers to what position on the ventral side of the low weight child in the positioning posture the diaper 1 can be properly worn. It can be difficult. Therefore, in the diaper 1 of the present embodiment, the area where the diaper 1 is folded toward the skin at the pair of folding positions Fd shown in FIG. 7 is set as the folding area 80 (see FIG. 8), and the diaper 1 is set from the side of the folding area 80. A mounting index 100 (hereinafter referred to as “mounting index 100B”) that can be visually recognized when viewed in the thickness direction is provided. The wearing index 100B is 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 weight child) is in the prone position or the positioning posture. It is a mark when the diaper 1 is pulled toward the ventral side of the wearer using the lower end of the ischium (R in FIG. 4) as an index. Specifically, as shown in FIG. 9, the wearing 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 ischium (R) of a low weight infant. By unfolding and wearing the diaper 1 after inserting it in this way, the degree of insertion of the diaper 1 into the body of a low-weight child becomes appropriate. As a result, a stable wearing state is realized, and stress when changing diapers by users such as nurses is reduced. In addition, stable wearing makes it easier for parents who are watching over to feel the feeling of clothes.

The wearing index 100B shown in FIG. 7 uses a heart-shaped index as an example, but the index is not limited to this, and any index that is easily visible to the diaper 1 changer can be used.

Further, as shown in FIG. 7, a pair of wearing indexes 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 the low weight child who is the wearer, and the wearing index 100B is a pair on both sides in the width direction and a position symmetrical with respect to the center CL1. Therefore, it is possible to confirm the deviation in the width direction with respect to the center of the body of the low weight infant. In addition, the wearing index 100B prevents deviations not only in the longitudinal direction but also in the width direction, thereby realizing a more stable wearing state and reducing stress when changing diapers.

Further, the mounting index 100B is located outside the absorber 2 in the width direction. By being outside the absorber 2 in the width direction, the visibility of the wearing index 100B in the folding region 80 when the diaper 1 is folded toward the skin along the folding position Fd from the unfolded state of FIG. 7 is improved.

Further, when the diaper 1 is applied to the body of a low-weight child, the unfolded diaper 1 in FIG. 7 is folded in half at the central portion in the longitudinal direction (center position CL2). Assuming that the waist circumference opening is on the upper side and the crotch lower part is on the lower side, the wearing index 100B is provided between the central ML of the diaper 1 and the lower end (corresponding to the central position CL2) in the vertical direction. By adjusting to the wearing index 100B, the portion between the lower end of the acetabulum (Q) and the lower end of the ischium (R) of the low weight child in the positioning posture (Y region in FIG. 4) is in the vertical direction. The first extending portion 20A, which is aligned between the central 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 during wearing, and is stable. It can be kept attached.

FIG. 10 is a diagram showing a modified example of the mounting index 100 (100B). The mounting index 100B (the portion indicated by the diagonal line 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. As the wearing index 100B, for example, when only one small index is provided, it is located between the lower end of the acetabulum (Q) and the lower end of the ischium (R) of a low weight child (Y region in FIG. 4). Even if the diaper 1 is inserted with the aim of causing it to move, there is a risk that it will shift within that area. However, in the vertical direction, the presence of the wearing index 100B in the entire area from the central ML to the lower end (CL2) makes it easier to understand the area for positioning with the body of the low weight child in the positioning posture, which is more appropriate. You can insert the diaper in the position.

Further, the mounting index 100B in the modified example shown in FIG. 10 may be provided together with the mounting index 100B of the present embodiment shown in FIG. 7 and the like. In that case, according to the wearing index 100B (FIG. 7) of the present embodiment, the portion between the lower end of the acetabulum (Q) and the lower end of the ischium (R) of the low-weight infant is specifically positioned at which position of the diaper 1. It is possible to easily confirm the degree of insertion of the diaper 1 by using the mounting index 100B (FIG. 10) of the modified example provided long in the vertical direction as a guide while making it easy to understand whether or not the diaper is brought into contact with the diaper.

<< About the central mounting index >>
Further, as shown in FIG. 7, the diaper 1 of the present embodiment is provided with a central wearing index 110 different from the wearing index 100 (100B) at the central portion in the longitudinal direction. Further, the central wearing index 110 is visible from the non-skin side of the diaper 1 as in the wearing index 100B.

FIG. 11 is a diagram showing a state in which the diaper 1 is pulled up when the diaper 1 is worn. When the diaper 1 is worn, the central part in the longitudinal direction is the position corresponding to the acetabulum of the inseam of the low weight child (Q in FIG. 4), and as shown in FIG. 11, the central wearing index 110 is the position of the low weight child. If the diaper 1 is pulled up so as to be located between the left and right acetabulums, the insertion condition will be appropriate. As a result, it becomes easy to realize a stable wearing state, and the stress of the diaper 1 user (nurse, etc.) when changing diapers is reduced. In addition, stable wearing makes it easier to feel the feeling of clothes.

Further, as shown in FIG. 7, a pair of center mounting indexes 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 central CL1 in the width direction of the diaper 1 is a position corresponding to the center of the body of the low weight child who is the wearer, and the central wearing index 110 is a pair and symmetrical positions on both sides in the width direction. It is possible to confirm the deviation of the weight child in the width direction with respect to the center of the body, and a more stable wearing state is realized. Further, as shown in FIG. 9B, when wearing the diaper 1 on a low weight child in a positioning posture, it is appropriate to bend the leg so that the heel of the low weight child is positioned on the pair of central wearing indexes 110. It makes it easier to take a positioning posture. Therefore, the central mounting index 110 also serves as a guide for the position of the foot in the positioning posture.

Further, the central mounting index 110 of the present embodiment overlaps with the absorber 2 in the width direction. The inseam 1C is a portion that is easily wrinkled by being sandwiched between the wearer's legs when worn, but the portion of the absorber 2 is less likely to wrinkle because the product is taut due to the thickness of the absorber 2. By arranging the central mounting index 110 so as to overlap with such an absorber 2 in the width direction, the changer of the diaper 1 can easily see the central mounting index 110. The central mounting index 110 of the present embodiment is provided so as to overlap the absorber 2 in the width direction, but the present invention is not limited to this, and at least a part of the central mounting index 110 is the absorber 2 in the width direction. It suffices if it overlaps with.

Further, the central wearing index 110 shown in FIG. 7 uses a flower pattern index as an example, but the index is not limited to this, and any index that is easily visible to the diaper 1 changer can be used.

FIG. 12 is a schematic plan view of the unfolded and stretched disposable diaper 1 provided with the symbol 120 as viewed from the non-skin side in the thickness direction. The symbol 120 is an example of a decorative symbol for decorating the diaper 1. The design 120 is provided on the non-skin side of the back sheet 4 by printing or the like, and is visible from the non-skin side of the diaper 1. In the present embodiment, among the symbols 120, the heart-shaped symbol is the symbol 120a and the flower-patterned symbol is the symbol 120b. The mounting index 100B has a similar shape to the symbol 120a, and the central mounting index 110 has a similar shape to the symbol 120b. In the present embodiment, the wearing index 100B and the central wearing index 110 both have a similar shape to the symbol 120 (120a or 120b) of the diaper 1, but may have the same size.

After wearing diaper 1 on a low-weight child in a positioning position, the low-weight child may be repositioned from the prone position to the supine position, at which time the first waist circumference 1A side (here, the abdomen). The wearing index 100B and the central wearing index 110 provided on the side) can be visually recognized by the watching nurse and parents. Since the wearing index 100B and the central wearing index 110 have the same shape or a similar shape to the symbol 120 (120a, 120b) of the diaper 1, each wearing index (100B, 110) is not an index but a symbol of the diaper 1. It becomes easier to be recognized as a part. In addition, such a configuration does not interfere with the world view of the design of the entire diaper 1, and gives a more clothing feeling.

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

The diaper 1 shown in FIG. 13 has a colored region 150 visible from the non-skin side of the diaper 1, which is colored with a predetermined color from both side ends of the back sheet 4 to the outer edge region of the absorbent core 2A in the width direction. Have. The term "end" as used herein means a range from the widthwise end of the backsheet 4 to 10 mm inward in the widthwise direction. The "outer edge region" of the absorbent core 2A means a range from the widthwise end (outer edge) of the absorbent core 2A to 10 mm inward and outward 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 the present embodiment, the colored region 150 is printed on the back sheet 4. Then, as shown in FIG. 14, when the diaper 1 is applied to the low weight child in the supine position and the diaper 1 is pulled up, the colored region 150 is used as a guide, so that the center of the crotch of the low weight child and the width of the diaper 1 are used as a guide. It becomes easier to align with the center of the direction. Further, the absorbent core 2A is a portion of the diaper 1 having high rigidity, but since the colored region 150 is provided outside the absorbent core 2A in the width direction, the absorbent core 2A and the rigid portion (absorbent core 2A) are provided. The boundary between the non-rigid portion (outside of the absorbent core 2A) becomes easy to understand, and the rigid portion can be prevented from hitting the leg circumference. Therefore, it is easy to wear it so as not to hinder the positioning posture and body movement of a low weight child.

Further, in the unfolded state shown in FIG. 13, the total length L1 in the longitudinal direction of the diaper 1 is set to the vertical center position ML on the first waist circumference portion 1A side, the center position CL2 in the longitudinal direction of the diaper 1, and the second waist circumference portion. Of the four regions divided into four equal parts by the central position NL in the vertical direction on the 1B side, the two regions located inside in the longitudinal direction (that is, the regions from ML to NL in the longitudinal direction) are referred to as the inner region CH. Then, the colored regions 150 are provided in the inner region CH in the longitudinal direction, respectively. In the two regions that are the medial region CH, at least one of the colored regions can be visually recognized regardless of whether the low weight infant is in the supine position or the prone position. By providing the colored regions 150 in the two regions that are the inner region CH, the rigid portion (absorbent core 2A) and the non-rigid portion (outside of the absorbent core 2A) are provided in both the supine and prone positions when worn. ) Borders are easier to understand. By preventing the rigid part from hitting the child's legs, it becomes easier to wear the child in a low-weight child so as not to interfere with the positioning posture and body movement.

Further, as shown in FIG. 13, the colored region 150 has a convex shape in which the inner edge 150in in the width direction protrudes inward in the width direction at the central portion in the longitudinal direction of the diaper 1. The central portion of the diaper 1 in the longitudinal direction is the inseam 1C, which is a portion sandwiched between both legs of a low-weight child when worn and whose length (width) in the width direction is narrowed. By projecting the colored region 150 inward in the width direction so as to follow such a narrowing shape of the diaper 1, the diaper 1 gives the impression that the diaper 1 is more closely fitted to the body and is worn, giving the diaper 1 a more clothing feeling. be able to.

Further, the predetermined color of the coloring region 150 is 196U, 217U, 250U, 494U, 502U, 503U, 510U, 517U, 670U, 671U, 677U, 678U, 684U, 685U in the color sample book of PANTONE (registered trademark).

=== Other embodiments ===
Although the embodiments of the present invention have been described above, the above-described embodiments are for facilitating the understanding of the present invention, and are not for limiting the interpretation of the present invention. Further, it is needless to say that the present invention can be changed or improved without departing from the spirit thereof, and the present invention includes an equivalent thereof.

In the above-described embodiment, the colored region 150 exemplifies a region colored with a predetermined color from both side ends of the backsheet 4 to the outer edge region of the absorbent core 2A in the width direction, but is not limited thereto. For example, the width (length in the width direction) of the colored region 150 may be narrower or wider. Further, the colored region 150 has a convex shape protruding inward in the width direction, but is not limited to this, and may have an arbitrary shape such as a rectangular shape or a wavy shape.

Further, the central mounting index 110 may be provided together with, for example, the mounting index 100A (the portion indicated by the diagonal line downward to the left) of the modified example shown in FIG. In the modified example of FIG. 6, since the mounting index 100A is provided in the entire area from the lower end 40ed of the fastening tape 40 to the central ML of the diaper 1 in the vertical direction, the region for alignment becomes easier to understand. There is. Then, by providing the central wearing index 110 together with such a wearing index 100A, when wearing a low weight child in the supine position, the diaper 1 is first aligned with the wearing index 100A as a guide, and then the diaper 1 is pulled up. At that time, it becomes easier to adjust the left-right (width direction) deviation and confirm the appropriate insertion condition with the central mounting index 110 as a guide, and the diaper 1 can be inserted more appropriately.

Further, the central mounting index 110 may be provided together with, for example, the mounting index 100B (the portion indicated by the diagonal line downward to the left) of the modified example shown in FIG. The wearing index 100B of 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, thereby providing an area for aligning with the body of a low weight child. It is easier to recognize. By providing the central wearing index 110 together with such a wearing index 100B, when wearing a low weight child in a positioning posture, the diaper 1 is aligned with the wearing index 100B as a guide, and then the buttocks of the low weight child are covered. When the diaper 1 is attached, it becomes easy to check the left-right (width direction) deviation with the central attachment index 110 as a guide. Therefore, a more stable wearing state can be realized for a low weight child.
