Description

diapers

technical field

The present invention relates to a diaper for infants used in medical facilities such as hospitals, particularly a diaper used for premature infants and low birth weight infants.

Background technique

Preterm and low birth weight infants are cared for in incubators in the neonatal intensive care unit (NICU). In general, normal disposable diapers and paper diapers are used for premature infants and low-birth-weight infants who are cared for in a neonatal intensive care unit, like other infants. However, the weight of a premature infant or the like is, for example, about 800 g to 2000 g. That is, the body size of premature infants and the like is smaller than that of other infants. Therefore, when an ordinary diaper is used for a premature infant or the like, a gap is likely to be formed between the body of the premature infant or the like and the diaper. When a gap is formed between the body of the premature infant or the like and the diaper, the excrement of the premature infant or the like may leak from the gap between the body of the premature infant or the like and the diaper. In addition, there are cases where a flexible tube is inserted into the body of a premature infant or the like, or where an excision process of the navel is necessary. In such a case, when an ordinary paper diaper is used, the body of a premature infant or the like may be completely covered by the paper diaper. Therefore, it is not preferable in terms of hygiene. Furthermore, the body size of premature infants and the like differs depending on the body weight. Therefore, if the size of the diaper is only reduced while maintaining the shape and structure of a normal diaper, it is difficult to cope with the differences in the body size of many premature infants and the like.

Patent Document 1 discloses a disposable diaper for premature infants or low birth weight infants used for premature infants and low birth weight infants who are cared for in an incubator in a neonatal intensive care unit. The disposable diaper for premature infants or low birth weight infants described in Patent Document 1 is worn on a premature infant or the like by placing the premature infant or the like on an absorbent body, and removing the absorbent body from the belt portion. After the protruding parts on both sides are wound around the waist and connected detachably, the absorptive main body is closely attached so as to cover the abdomen from the back through the crotch. According to the description of Patent Document 1, since the body movements of premature infants and low birth weight infants are restricted, the absorbent body does not open even if it is not locked by the belt portion. Moreover, according to the description of patent document 1, the front-end|tip part of an absorptive main body can be pinched|interposed between the belt part wound around a waist, and a body just in case.

SUMMARY OF THE INVENTION

However, the urine excretion position of men is located on the front side (ventral side) compared with the urine excretion position of women. That is, males excrete urine from the front side (ventral side) as compared with females. Therefore, although the body movements of premature infants and low-birth-weight infants are restricted, the urine of premature infants and other males may flow into premature infants only by the fact that the absorbent body is tightly attached to the abdomen or sandwiched between the belt and the body. The child waits on the ventral side of itself. In addition, when the absorbent body is in close contact with the abdominal side, the part in close contact with the abdominal side may be caught by a person performing treatment and care, and the treatment and care may be hindered. Therefore, a diaper that can be worn in a manner corresponding to the difference in body size between premature infants and low birth weight infants, and which can suppress interference with treatment and care, is desired.

The present invention has been made in order to solve the above-mentioned problems, and an object of the present invention is to provide a device that can be worn in a manner corresponding to the difference in body size of infants (premature infants and low birth weight infants), which can suppress the need for treatment and nursing care. The diapers that get in the way.

According to the present invention, the above-mentioned problems are solved by the following disposable diaper, which is characterized by comprising: a nonwoven fabric extending from the back side of the infant through the crotch to the abdominal side; and a back sheet formed from When the non-woven fabric is observed, it is arranged on the opposite side of the infant to suppress the permeation of the excrement discharged by the infant; the absorber is arranged between the non-woven fabric and the back sheet. absorb the excrement passing through the non-woven fabric; and a belt portion fixed to at least any one of the non-woven fabric and the back sheet and extending toward the non-woven fabric It extends on both sides of the direction crossing the direction of the nonwoven fabric, and has a connecting portion that is detachably connected to the non-woven fabric; at least a part of the portion where the non-woven fabric and the back sheet are bonded to each other is formed as an extension portion, the The extension part does not overlap with the absorber, and further extends from the end of the abdomen side of the absorber toward the abdomen side; in the direction in which the nonwoven fabric extends, the length of the extension part is greater than The length of the connection portion is long.

According to the structure, at least a part of the portion where the nonwoven fabric and the back sheet are bonded to each other is formed as an extension that does not overlap with the absorber. That is, the absorber is not arranged in the extension part. The extension portion extends further toward the abdominal side from the end portion on the abdominal side of the absorber. In addition, in the direction in which the nonwoven fabric extends, the length of the extending portion is longer than the length of the connecting portion. Since the diaper has such an extension, the childcare worker of the baby can adjust the length extending from the back of the baby through the crotch to the abdomen by folding the extension according to the size of the baby, and can be worn by the baby. A diaper that matches your baby's body size. Thereby, the diaper of the present invention can be worn in accordance with the difference in body size of infants. Therefore, it is possible to suppress the generation of a gap between the body of the infant and the diaper due to the curling of the diaper, and it is possible to prevent the excrement of the infant from leaking from the gap between the body of the infant and the diaper. In addition, since the extension portion is folded and connected to the connection portion according to the size of the infant, it is possible to prevent the extension portion from being caught by the person performing treatment and care, and to prevent the treatment and care from being hindered. In addition, a childcare worker for infants (premature infants and low birth weight infants) folds the extension portion to the opposite side of the infant according to the size of the infant, and connects the connecting portion of the belt portion to the folded extension portion. In this case, the entire width of the connection portion in the extending direction can be reliably accommodated in the folded extension portion by folding the connection portion at least along the end portion of the absorber. Therefore, the connection portion is connected to the extension portion over the entire width thereof, so that the connection between the connection portion and the extension portion can be strengthened.

Preferably, the connecting portion is a hook and loop fastener, and the front tape connected to the hook and loop fastener is provided on the surface of the non-woven fabric.

According to the said structure, the front tape connected with the hook-and-loop fastener which is a connection part is provided in the surface of the nonwoven fabric. Thereby, the connection part is connected to the surface of the nonwoven fabric more reliably.

Preferably, the bottom sheet has a plurality of crease marks, and the plurality of crease marks are provided in the extending portion at positions corresponding to the weight of the infant.

According to this structure, the caregiver of the infant can fold the extension to the opposite side of the infant according to the size of the infant (the weight of the infant) using the crease mark provided on the back sheet as a reference. Thereby, it is possible to easily put the diaper on the infant, and it is possible to suppress the burden on the infant.

Preferably, the non-woven fabric has a plurality of buttock marks, and the plurality of buttock marks are arranged at positions corresponding to the weight of the infant.

According to the above configuration, the nurse of the infant can place the infant on the diaper so that the buttocks and the buttock mark of the infant are matched according to the size of the infant. Therefore, the caregiver of the infant can place the infant in an appropriate position of the diaper with one operation, and it is possible to suppress the burden on the infant. In addition, since the childcare worker of the infant can place the infant at an appropriate position of the diaper, it is possible to suppress a gap between the body of the infant and the diaper due to the curling of the diaper, and it is possible to prevent the excrement of the infant from passing through the diaper. gap leaks.

Preferably, the back sheet has a first hook and loop fastener and a second hook and loop fastener connected to the first hook and loop fastener in the extending portion.

According to the said structure, the back sheet has a 1st hook-and-loop fastener and a 2nd hook-and-loop fastener. The first hook-and-loop fastener and the second hook-and-loop fastener are provided on the extension part and are configured to be able to be connected to each other. Therefore, when the childcare worker of the infant knows the size of the infant (the weight of the infant), before placing the infant in the diaper, the first hook and loop fastener is folded over the extension according to the size of the infant. The state of the folded extension can be maintained by being connected with the second hook and loop fastener. Compared with the case where the babysitter is placed in the diaper and then folded over the extension portion, it is possible to suppress stimulation to the baby and increase the burden on the baby.

Detailed ways

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

It should be noted that, since the embodiments described below are preferred specific examples of the present invention, various technically preferable limitations are added. Otherwise, the scope of the present invention is not limited only to these embodiments. In addition, in each drawing, the same code|symbol is attached|subjected to the same component, and a detailed description is abbreviate|omitted suitably.

1-4, the diaper which concerns on embodiment of this invention is demonstrated. The diaper 2 according to the present embodiment is called a disposable diaper (diaper), a paper diaper (diaper), or the like, and is used for infants and young children. Specifically, the diaper 2 according to the present embodiment is used for premature infants and low birth weight infants in medical facilities such as hospitals.

The diaper 2 is sold in a folded state substantially at the center in the longitudinal direction of the diaper 2 . On the other hand, the diaper 2 is unfolded as shown in FIGS. 1 and 2 during use. In addition, one end in the longitudinal direction of the diaper 2 is disposed on the back side of the infant, and the other end in the longitudinal direction of the diaper 2 is disposed on the abdomen of the infant. In the diaper 2 shown in FIGS. 1 and 2 , the direction of the arrow D11 corresponds to the back side of the infant, and the direction of the arrow D12 corresponds to the ventral side of the infant. Moreover, the substantially center part in the longitudinal direction of the diaper 2 is arrange|positioned at the crotch part of an infant.

As shown in FIGS. 1 and 2 , the diaper 2 includes a nonwoven fabric 3 , a backsheet 4 , an absorber 5 , and a belt portion 6 . The nonwoven fabric 3 is provided on the surface side which is in contact with the skin of the infant. In the specification of this application, "surface" means the surface which contacts the body of the user (infant) of a diaper. The back sheet 4 is provided on the back side opposite to the infant when viewed from the nonwoven fabric 3 . In the specification of the present application, the "back surface" refers to the surface on which the diaper 2 is exposed to the outside in a state where the diaper 2 is worn by an infant. The absorber 5 is provided between the nonwoven fabric 3 and the back sheet 4 .

The nonwoven fabric 3 extends from the back side of the infant to the ventral side through the crotch. That is, the nonwoven fabric 3 extends in the extending direction D1 shown in FIGS. 1 and 2 . The extending direction D1 corresponds to "the direction in which the nonwoven fabric and the back sheet extend" and the "longitudinal direction of the diaper". In the extending direction D1, the length of the nonwoven fabric 3 is substantially the same as the length of the diaper 2, for example, about 100 mm or more and 300 mm or less. However, the length in the extending direction D1 of the nonwoven fabric 3 is not limited to this.

The non-woven fabric 3 is a material that does not easily fluff, so it is used as a surface material that comes into contact with the skin of infants and young children, and has a function of allowing excretions such as urine of the infants and young children to pass through the absorber 5 . The nonwoven fabric 3 can be called, for example, a surface sheet, a top sheet, or the like. The non-woven fabric 3 is a hot-melt fiber obtained by fiberizing a synthetic resin (for example, PET/PE, PP/PE, PET/EP, PP/EP) by thermal bonding method (Thermal bond), spunbond method (Spunbond) ), etc., are formed by melting without using a binder.

As shown in FIG. 4 , the nonwoven fabric 3 of the present embodiment is formed of a plurality of layers, and has a first fiber layer 33 and a second fiber layer 34 . The first fiber layer 33 is disposed on the surface in direct contact with the skin of the infant, and has an uneven surface 333 having a plurality of concave portions 331 and a plurality of convex portions 332 . Thereby, the area of the nonwoven fabric 3 in contact with the skin is reduced, and discomfort, diaper rash, and the like are prevented. The second fiber layer 34 overlaps with the back surface of the first fiber layer 33 (the inner side of the diaper 2 ), and has a flat sheet shape as a whole.

By making the convex part 332 of the first fiber layer 33 swell to the opposite side of the second fiber layer 34, the inner space S of the convex part 332 is formed as a part where the fibers are sparse. Thereby, even when the urine of an infant is not quickly absorbed by the absorber 5 , it can be temporarily stored in the inner space S of the convex portion 332 . The first fiber layer 33 and the second fiber layer 34 are partially crimped to each other.

Three-dimensional pleated portions 35 are provided on both outer sides in the width direction D2 of the uneven surface 333 . The three-dimensional pleated portion 35 intercepts urine that is not temporarily stored in the uneven surface 333 , which is a so-called side leakage prevention barrier. The width direction D2 corresponds to "the direction intersecting the direction in which the nonwoven fabric and the back sheet extend" and "the width direction of the diaper", and is orthogonal to the extending direction D1. In the width direction D2, the length (width) of the nonwoven fabric 3 is, for example, about 50 mm or more and about 150 mm or less. However, the length of the nonwoven fabric 3 in the width direction D2 is not limited to this.

Leg gathers 36 are provided on both outer sides in the width direction D2 of the three-dimensional gathers 35 . The leg gathers 36 are in close contact with the crotch of the infant, and even when excreted urine or the like leaks from the three-dimensional gathers 35 , the urine and the like can be prevented from leaking to the outside of the diaper 2 .

The elastic body 7 is provided inside each of the three-dimensional gathers 35 and the leg gathers 36 . The elastic body 7 is arranged along the extending direction D1 and has elastic shrinkability. For example, an elongated rubber such as a rubber thread can be used as the elastic body 7 . A sheet-like or mesh-like rubber can be used as the elastic body 7 . The elastic body 7 is fixed in a stretched state, and when no external force is applied, a contraction force is applied to the three-dimensional gathers 35 and the leg gathers 36 . Therefore, as shown in FIGS. 3 and 4 , the three-dimensional gathers 35 and the leg gathers 36 stand up when worn due to the elastic shrinkability of the elastic body 7 . And, as shown in FIG. 3, when the external force is not applied to the diaper 2, the state of the diaper 2 bent in an arc shape is elastically maintained.

As a modification of the nonwoven fabric 3, for example, in a plan view of the diaper 2 when viewed from the front side (see FIG. 1 ), the convex portion 332 may have a substantially hexagonal shape, and the concave portion 331 may have a substantially hexagonal shape with the convex portion 332. The hexagonal corresponding to the groove shape (not shown). Of course, the shapes of the concave portion 331 and the convex portion 332 are not limited to this. In addition, as the nonwoven fabric 3, the first fiber layer 33 and the second fiber layer 34 can be subjected to mesh processing, and a nonwoven fabric having numerous through holes can be used. By such mesh processing, the non-woven fabric 3 allows urine and excrement such as soft stools unique to newborns to quickly permeate through the absorber 5 . Therefore, the excrement easily penetrates into the absorber 5 .

The back sheet 4 is used as a back material provided on the opposite side to the infant when viewed from the nonwoven fabric 3, and suppresses the permeation of excrement discharged from the infant. The back sheet 4 is a sheet exposed to the outside when the diaper 2 is worn by an infant, and is formed of a flexible material such as a thin plastic film. Specifically, a polyethylene film, a polyethylene laminate paper, or the like can be used as the material of the back sheet 4 . Preferably, the back sheet 4 is impermeable to urine and permeable to water vapor. Thereby, the hot flash of the part covered with the diaper 2 is prevented.

The absorber 5 is provided between the nonwoven fabric 3 and the back sheet 4 , and has a function of absorbing the excrement passing through the nonwoven fabric 3 . That is, the absorber 5 is a portion for absorbing and retaining liquid such as discharged urine. The absorber 5 is preferably an absorber having high retention of absorbed liquid, and a relatively thin absorber. Preferably, the absorber 5 has a small volume. As the absorber 5, for example, a pulp absorber formed by mixing or dispersing a polymer as an absorbent material in pulp, or a pulp absorber formed by dispersing a polymer in pulp, or a sheet made of pulp or the like arranged in a high density with a polymer can be used. A polymer sheet or the like formed in the form of a sheet.

As shown in FIG. 4, the absorber 5 is surrounded by the thin fabric 52 and is not exposed to the outside. As the thin fabric 52, a material obtained by sheeting a soft material for absorbing liquids, etc., such as pulp, rayon, cotton, kenaf, bagasse, silk, etc., can be used alone or in combination. Hydrophilic-treated fibers (polyolefin-based, polyester, acrylic) and the like.

The belt portion 6 is fixed to at least one of the nonwoven fabric 3 and the back sheet 4 , and extends toward both sides of the direction (width direction D2 ) intersecting the extending direction D1 of the nonwoven fabric 3 . Specifically, the belt portion 6 has a first belt main body 61 and a second belt main body 62 . The first belt main body 61 is a belt-shaped member extending toward one of the width directions D2. The second belt main body 62 is a belt-shaped member extending toward the other direction (the direction opposite to the first belt main body 61 ) in the width direction D2 .

Preferably, the belt portion 6 has stretchability in the width direction D2. For example, as the material of the belt portion 6, a stretchable nonwoven fabric can be used. Alternatively, as a material of the belt portion 6, a belt-shaped member in which a plurality of nonwoven fabrics are bonded and an elastic body such as a rubber yarn having elastic shrinkability is provided between the plurality of nonwoven fabrics may be used.

A connecting portion 63 is provided at the front end portions of the first belt main body 61 and the second belt main body 62 . The connection part 63 is detachably connected to the nonwoven fabric 3 . Specifically, the connection portion 63 is a hook and loop fastener. Moreover, as shown in FIG.1 and FIG.3, the front tape 32 is provided in the edge part surface of the ventral side of the nonwoven fabric 3, and this front tape 32 is connected with the connection part 63 which is a hook-and-loop fastener. Details of the connection between the connection portion 63 and the front belt 32 will be described later.

The connection part 63 is not limited to a hook-and-loop fastener, and may be an adhesive layer provided with an adhesive. Even in this case, the connection portion 63 serving as the adhesive bond layer is detachably connected to the nonwoven fabric 3 . It should be noted that the front band 32 does not necessarily need to be provided.

Therefore, in general, preterm infants and low birth weight infants who are cared for in the neonatal intensive care unit use ordinary disposable diapers and paper diapers in the same way as other infants. However, in this way, a gap is likely to be formed between the body of the premature infant or the like and the diaper, and the excrement of the premature infant or the like may leak from the gap between the body of the premature infant or the like and the diaper. In addition, the body size of premature infants and the like varies according to body weight. Therefore, if the size of the diaper is only reduced while maintaining the shape and structure of an ordinary diaper, it is difficult to cope with the differences in the body size of many premature infants and the like.

So far, there are disposable diapers for premature or low birth weight infants. For example, a disposable diaper for premature infants or low birth weight infants is worn on premature infants or the like by placing the premature infant or the like on the absorbent body, wrapping the belt around the waist and detachably connecting the absorbent body. It is closely attached so as to cover from the back through the crotch to the abdomen. However, the discharge position of male urine is located on the front side (ventral side) compared with the discharge position of female urine. That is, compared with women, men excrete urine from a position on the front side (ventral side). Therefore, although the body movements of premature infants and low birth weight infants are restricted, if the absorber is only attached to the ventral side, the urine of male premature infants and the like may flow to the ventral side of the premature infant or the like. In addition, the part that is in close contact with the abdomen may be caught by the person who performs treatment or care, thereby hindering the treatment and care.

In this regard, the diaper 2 according to the present embodiment has the extension portion 31 . As shown in FIGS. 1 and 2 , in plan view, the extension 31 does not overlap with the absorber 5 provided on the back side of the nonwoven fabric 3 , but extends from the abdominal end 51 of the absorber 5 toward the abdomen. The side extending portion is a portion where the nonwoven fabric 3 and the back sheet 4 are bonded to each other. In other words, the extension portion 31 is a portion where the nonwoven fabric 3 and the back sheet 4 extend in the direction of the arrow D12 from the end 51 on the abdominal side of the absorber 5 in the same plan view, and is the nonwoven fabric 3 and the back sheet 4 4 parts that are glued to each other. Therefore, the absorber 5 is not arranged in the extension part 31 . In the extending direction D1 of the nonwoven fabric 3 , the length L1 of the extending portion 31 is longer than the length L2 (about 2 cm) of the connecting portion 63 of the belt portion 6 . For example, the length L1 of the extension part 31 is about twice or more and about five times or less, preferably three times, of the length L2 of the connection part 63 . When the length L1 of the extension part 31 is 4 cm or more, the folding operation described later can be easily performed. In the diaper 2 shown in FIGS. 1 and 2 , the length L2 of the connecting portion 63 in the extending direction D1 is substantially the same as the length of the first belt main body 61 and the length of the second belt main body 62, but it is not limited to this , may be shorter than the length of the first belt main body 61 and the length of the second belt main body 62 .

Since the diaper 2 has such an extension portion 31, the childcare worker of the infant can fold the extension portion 31 according to the size of the infant, so as to adjust the length extending from the back side of the infant through the crotch portion to the abdomen side, Put on the diaper 2 of the size that matches the body size of the baby. Thereby, the diaper 2 according to the present embodiment can be worn in accordance with the difference in body size of infants. Therefore, it is possible to suppress the generation of a gap between the body of the infant and the diaper 2 due to the deflection of the diaper 2, and to prevent the excrement of the infant from leaking from the gap. In addition, the extension portion 31 is folded and connected to the connection portion 63 according to the size of the infant, so that it can be prevented from being caught by a person performing treatment or care, and interference with treatment and care can be suppressed.

According to the diaper 2 according to the present embodiment, the length L1 of the extending portion 31 is longer than the length L2 of the connecting portion 63 in the extending direction D1 of the nonwoven fabric 3 . Therefore, as shown in FIG. 7 , the caregiver of infants (premature infants and low-birth-weight infants) folds the extension portion 31 to the opposite side of the infant according to the size of the infant, so that the connecting portion of the belt portion 6 is folded. When the 63 is connected to the folded extension portion 31, at least the connecting portion 63 is folded along the end portion 51 of the absorber, so that the entire width (length L 2 ) of the connecting portion 63 in the extending direction D1 can be reliably is accommodated in the folded extension portion 31 . Therefore, the connection portion 63 is provided so as to be connected to the extension portion 31 over the entire width thereof, and the connection between the connection portion 63 and the extension portion 31 can be strengthened.

Next, with reference to FIGS. 5-7, the structure of the diaper 2 which concerns on this embodiment is demonstrated further, and the usage method of the diaper 2 is demonstrated. First, when putting on the diaper 2 for the infant, the childcare worker unfolds the diaper 2 (see FIGS. 1 and 2 ), and places the infant on the diaper 2 .

At this time, as shown in FIGS. 1 and 5 , the nonwoven fabric 3 has a plurality of buttock marks M1, M2, and M3. The buttock marks M1, M2, and M3 are provided at positions corresponding to the weight of the infant on the surface side of the center portion of the absorber 5 in the extending direction D1 of the nonwoven fabric. The buttock marks M1, M2, and M3 extend linearly along the width direction D2. The buttock marks M1, M2, and M3 may have a form in which a continuous straight line extends in the width direction D2, or may have a form in which separated portions are arranged and extended in the width direction D2, for example, a dotted line or a dotted line. For example, the buttock marks M1, M2, and M3 may be formed on the nonwoven fabric 3 by printing. Alternatively, the buttock marks M1, M2, and M3 may be formed by embossing, for example, like the uneven surface 333 described in FIG. 4 .

When putting on the diaper 2 for the infant, the nurse of the infant can place the infant in such a way that the buttocks of the infant and the buttock marks M1, M2, and M3 are matched according to the size of the infant (the weight of the infant) on diapers 2. That is, the buttock mark M1 is a mark for infants with a weight of, for example, about 800 g. The childcare worker of the infant places the infant on the diaper 2 so that the buttocks of the infant weighing about 800 g, for example, match the buttock mark M1, thereby placing the infant at an appropriate position in the diaper 2. . Specifically, the caregiver of the infant can fit the crotch of the infant and the substantially central portion of the absorber 5 in the extending direction D1. The buttocks mark M2 is a mark for infants and young children with a body weight of, for example, about 1500 g. The childcare worker of the infant can place the infant on the diaper 2 so that the buttocks of the infant weighing about 1500 g, for example, match the buttock mark M2, so that the infant can be placed at an appropriate position in the diaper 2. . The buttock mark M3 is a mark for infants and young children with a weight of, for example, about 2000 g. The childcare worker of the infant can place the infant on the diaper 2 so that the buttocks of the infant weighing about 2000 g, for example, match the buttock mark M3, and the infant can be placed at an appropriate position in the diaper 2. .

In this way, the nurse of the infant can place the infant on the diaper 2 so that the buttocks of the infant and the buttock marks M1, M2, M3 are matched according to the size of the infant, and can place the infant on the diaper 2 in one operation. The appropriate position of the diaper 2. That is, the caregiver of the infant can adjust the relative position of the infant and the diaper 2 to an appropriate position with one operation, and unnecessary movement of the infant can be prevented. As a result, it is possible to suppress an increase in the burden on the infant. In addition, since the childcare worker of the infant can place the infant at an appropriate position of the diaper 2 , it is possible to suppress the generation of a gap between the body of the infant and the diaper 2 due to the deflection of the diaper 2 , thereby suppressing the occurrence of a gap between the infant's body and the diaper 2 . Excrement leaks out of this gap.

In addition, the weight of the infant corresponding to each of the buttock marks M1, M2, and M3 described above is an example, but is not limited to this. On the other hand, the weight of the infant corresponding to the buttocks mark M1 provided on the back side is lighter than that of the infants corresponding to the buttocks mark M2 and the buttocks mark M3, respectively. On the other hand, the weight of the infant corresponding to the buttocks mark M3 provided on the ventral side is heavier than the weight of the infants corresponding to the buttocks mark M1 and the buttocks mark M2, respectively. The buttocks mark M2 provided between the buttocks mark M1 and the buttocks mark M3 is heavier than the infant corresponding to the buttocks mark M1 and lighter than the infant corresponding to the buttocks mark M3.

Next, the childcare worker of the infant covers the abdomen of the infant with the ventral portion of the diaper 2 . At this time, as shown in FIGS. 2 and 5 , the back sheet 4 has a plurality of crease marks M11 , M12 , and M13 . The crease marks M11 , M12 , and M13 are provided on the portion on the back side of the extension portion 31 (the surface on the opposite side to the nonwoven fabric 3 among the surfaces of the back sheet 4 ). The crease marks M11, M12, and M13 extend linearly along the width direction D2. The crease marks M11, M12, and M13 may have a form in which a continuous straight line extends in the width direction D2, or may have a form in which separated portions are arranged and extended in the width direction D2, for example, a dotted line or a dotted line. For example, the crease marks M11, M12, M13 may be formed on the back sheet 4 by printing. Alternatively, the crease marks M11 , M12 , and M13 may be formed by embossing, for example, like the uneven surface 333 described in FIG. 4 .

The crease marks M11, M12, and M13 are provided at positions corresponding to the weight of the infant. That is, the crease mark M11 is a mark for infants with a weight of, for example, about 800 g. As shown in FIG. 6 , by folding the extension 31 to the opposite side of the infant based on the position of the crease mark M11, the childcare worker of the infant can adjust the weight of the infant, for example, about 800 g. The extension portion 31 is folded over at the corresponding position. The crease mark M12 is a mark for infants with a body weight of, for example, about 1500 g. As shown in FIG. 6 , the childcare worker of the infant can fold the extension portion 31 to the opposite side of the infant using the position of the crease mark M12 as a reference, so as to be able to adjust the size of the infant with a weight of, for example, about 1500 g. The extension portion 31 is folded over at the corresponding position. The crease mark M13 is a mark for infants with a body weight of, for example, about 2000 g. As shown in FIG. 6 , the childcare worker of the infant can fold the extension 31 to the opposite side of the infant using the position of the crease mark M13 as a reference, so as to be able to adjust the size of the infant with a weight of, for example, about 2000 g. The extension portion 31 is folded over at the corresponding position.

In this way, the childcare worker of the infant can fold the extension 31 in accordance with the size of the infant (the weight of the infant) using the crease marks M11, M12, and M13 provided on the back sheet 4 as a reference. At this time, as shown in FIG. 5 , in the extension portion 31 , the first hook and loop fastener 41 and the second hook and loop fastener 42 are provided on the surface of the back sheet 4 on the opposite side to the nonwoven fabric 3 . . The first hook-and-loop fastener 41 and the second hook-and-loop fastener 42 can be connected to each other on the surface on the opposite side to the nonwoven fabric 3 among the surfaces of the backsheet 4 . For example, any one of the first hook and loop fastener 41 and the second hook and loop fastener 42 is a male part of the hook and loop fastener. For example, any other of the first hook and loop fastener 41 and the second hook and loop fastener 42 is a female part of the hook and loop fastener. In addition, the 2nd hook-and-loop fastener 42 does not necessarily need to be provided in the extension part 31, and may be provided in the crotch part side when seeing from the edge part 51 of the abdominal side of the absorber 5, for example.

Thereby, when the childcare worker of the infant knows the size of the infant (the weight of the infant), before placing the infant in the diaper 2, the childcare worker folds the extension 31 in accordance with the size of the infant to make the first The hook and loop fastener 41 and the second hook and loop fastener 42 are connected to each other so that the state of the folded extension portion 31 can be maintained. Compared with the case where the babysitter is placed on the diaper 2 and the extension portion 31 is folded back by the caregiver of the infants, it is possible to suppress stimulation to the infants and increase the burden on the infants.

In addition, since the absorber 5 is not disposed in the extension portion 31, when the extension portion 31 is folded back, the extension portion 31 can be prevented from becoming rigid or bulky. Therefore, the childcare worker of the infant can easily fold the extension portion 31 .

Next, as shown in FIG. 7 , the childcare worker of the infant covers the abdomen of the infant with the abdominal portion of the diaper 2 while maintaining the state of the extension portion 31 on the opposite side of the infant, and folds the belt portion. The connecting portion 63 of 6 is connected to the surface of the nonwoven fabric 3 exposed on the side opposite to the infant. At this time, as described in FIGS. 1 and 3 , the front tape 32 is provided on the end surface of the ventral side of the nonwoven fabric 3 . Specifically, the front tape 32 is provided on the surface of the nonwoven fabric 3 in the extension portion 31 . The childcare worker of the infant covers the abdomen of the infant with the abdominal portion of the diaper 2 , and connects the connection portion 63 of the belt portion 6 to the front belt 32 . Thereby, the connection part 63 is connected to the surface of the nonwoven fabric 3 in the extension part 31 more reliably.

As shown in FIG. 7 , the diaper 2 according to the present embodiment is put on the infant (premature infant and low birth weight infant) in this manner. The nurse of the infant places the infant on the diaper 2 so that the buttocks of the infant and the buttock marks M1, M2, and M3 are matched according to the size of the infant, and the crease marks M11, M12, and M13 are used as the reference. The extension portion 31 is folded back according to the size of the infant, so that the diaper 2 can be easily put on the infant, and the burden on the infant can be suppressed.

The embodiments of the present invention have been described above. However, the present invention is not limited to the above-described embodiments, and various modifications can be made without departing from the scope of the claims. A part of the structure of the above-mentioned embodiment can be omitted, or it can be combined arbitrarily in the form different from the above.
