[Solution] This diaper 2 is provided with: a nonwoven fabric 3 extending from the back side to the abdomen side of an infant through the crotch part; a back sheet 4 for preventing the infant's excretions from soaking through; an absorber 5 that is provided between the nonwoven fabric 3 and the back sheet 4 and absorbs excretions that soak through the nonwoven fabric 3; and a belt part 6 having a joining part 63 that can be detachably joined to the nonwoven fabric 3. At least a part of an area where the nonwoven fabric 3 and the back sheet 4 are mutually adhered does not overlap the absorber 5, and forms an extension part 31 extending from an abdomen-side end part of the absorber 5 further toward the abdomen. In terms of the direction in which the nonwoven fabric 3 extends, the length L1 of the extension part 31 is longer than the length L2 of the connection part 63.

Description

Diapers

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

Premature babies and low birth weight babies are raised in incubators in the neonatal intensive care unit (NICU). Generally, ordinary disposable diapers and paper diapers are used for premature babies and low birth weight infants raised in a neonatal intensive care unit, like other infants. However, the weight of a premature baby or the like is about 800 g or more and 2000 g or less, for example. That is, the body of a premature baby or the like is smaller than the bodies of other infants. Therefore, when a normal diaper is used for a premature baby or the like, a gap is likely to be generated between the body of the premature baby or the like and the diaper. If a gap occurs between the body of a premature baby and a diaper, excrement such as a premature baby may leak from the gap between the body of a premature baby and the diaper. In addition, a tube may be attached to the body of a premature infant or the like, or a treatment for removing the navel may be necessary. In such a case, when a normal paper diaper is used, the paper diaper may completely cover the body of a premature baby or the like. Therefore, it is not preferable also in terms of hygiene. Furthermore, the body size of premature babies and the like varies depending on body weight. Therefore, it is difficult to cope with the difference in body size of a plurality of premature babies and the like only by reducing the size of the diaper while maintaining the shape and structure of the normal diaper.

Patent Document 1 discloses a disposable diaper for premature babies or low birth weight infants used for premature babies and low birth weight infants raised 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 mounts premature babies etc. on the absorbent main body, and wraps the portions protruding from both sides of the absorbent main body in the belt section around the waist After freely connecting, the absorbent main body is applied so as to cover from the back side through the crotch part to the abdominal side, so that it can be attached to a premature baby or the like. According to the description in Patent Document 1, since the body movement of premature babies and low birth weight infants is limited, the absorbent main body does not open even if it is not locked by the belt portion. In addition, according to the description in Patent Document 1, as a precaution, the front end portion of the absorbent main body may be sandwiched between the belt portion wound around the waist and the body.

Japanese Patent No. 5069532

However, the man's urine discharge position is on the front side (ventral side) of the woman's urine discharge position. That is, a man discharges urine from a position on the front side (ventral side) as compared with a woman. Therefore, although the movement of the body of premature babies and low birth weight infants is limited, it is only possible for the male body to be placed on the ventral side or be sandwiched between the belt and the body. There is a risk that urine from premature babies, etc. may fall on the ventral side of premature babies. Moreover, when the absorptive main body is applied to the abdomen, the part applied to the abdomen may be caught by a person who performs treatment or nursing, which may hinder treatment or nursing. Therefore, a diaper that can be worn according to the difference in body size between premature infants and low birth weight infants and that can prevent the treatment and nursing from being hindered is desired.

The present invention has been made in order to solve the above-described problems, and can be worn according to the difference in body size of infants (premature infants and low birth weight infants), which hinders treatment and nursing. It aims at providing the diaper which can suppress that.

According to the present invention, the subject is a non-woven fabric that extends from the infant's back to the abdomen through the crotch, and is provided on the opposite side of the infant as viewed from the non-woven fabric, and allows permeation of excreta discharged by the infant. The non-woven fabric is fixed to at least one of the non-woven fabric and the back sheet, the back sheet to be suppressed, the absorber that is provided between the non-woven fabric and the back sheet, and absorbs the excrement that has passed through the non-woven fabric. A belt portion extending toward both sides in a direction intersecting with the extending direction and detachably connectable to the nonwoven fabric, and the nonwoven fabric and the backsheet are bonded to each other At least a part of the portion does not overlap with the absorber, but is an extended portion that extends further from the abdomen end of the absorber toward the abdomen. Cage, in the direction in which the nonwoven fabric is extended, the length of the extended portion is solved by the diaper, characterized in that longer than the length of the connecting portion.

According to the above configuration, at least a part of the portion where the nonwoven fabric and the backsheet are bonded to each other is an extending portion that does not overlap the absorber. That is, the absorber is not disposed in the extending portion. The extending portion extends further toward the ventral side from the ventral end of the absorbent body. And in the direction where the nonwoven fabric extended, the length of the extension part is longer than the length of a connection part. Since the diaper has such an extended portion, the infant childcare person can fold the extended portion according to the size of the infant's body, so that the length extends from the infant's back to the crotch and extends to the ventral side. The baby can be fitted with a diaper of a size that matches the size of the baby's body. Thereby, the diaper of this invention can be mounted | worn corresponding to the difference in the magnitude | size of the infant's body. Therefore, it can suppress that the clearance gap by the bending of a diaper arises between an infant's body and a diaper, and can suppress the excrement of the infant from leaking through the clearance gap between them. In addition, the extension part is folded back according to the size of the infant's body and connected to the connecting part, so that it is prevented from being caught by a person who performs treatment or nursing or hindering treatment or nursing. Can do. In addition, a childcare worker of an infant (premature infant or low birth weight infant) folds the extension part to the opposite side of the infant according to the size of the infant's body, and connects the connecting part of the belt part to the folded extension part. When connecting, at least the connection part can be folded back along the end part of the absorber, so that the entire width in the extending direction of the connection part can be reliably accommodated in the folded-up extension part. Therefore, the connecting portion is connected to the extending portion over its entire width, and the connection between the connecting portion and the extending portion can be strengthened.

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

According to the above configuration, the frontal tape connected to the surface fastener as the connecting portion is provided on the surface of the nonwoven fabric. Thereby, a connection part is reliably connected with the surface of a nonwoven fabric.

Preferably, the back sheet has a plurality of crease marks provided at positions corresponding to the weight of the infant in the extended portion.

According to the said structure, the infant childcare person turns the extending part back to the opposite side of the infant according to the size of the infant's body (infant's weight), using the crease mark provided on the back sheet as a guide. be able to. Thereby, while being able to attach a diaper to an infant easily, it can suppress that a burden is applied to an infant.

Preferably, the non-woven fabric has a plurality of buttocks marks provided at positions corresponding to the weight of the infant.

According to the above-described configuration, the infant childcare person can place the infant on the diaper with the buttocks of the infant aligned with the mark of the buttocks according to the size of the infant's body. Therefore, the infant childcare person can place the infant on an appropriate position of the diaper in one operation, and can suppress the burden on the infant. In addition, since the infant childcare person can place the infant at an appropriate position in the diaper, it is possible to suppress the occurrence of a gap due to the bending of the diaper between the infant's body and the diaper, and the excrement of the infant from the gap. Leakage can be suppressed.

Preferably, the back sheet has a first surface fastener and a second surface fastener connected to the first surface fastener in the extended portion.

According to the above configuration, the backsheet has the first surface fastener and the second surface fastener. The first surface fastener and the second surface fastener are provided in the extending portion and can be connected to each other. Therefore, if the child care worker knows the size of the infant's body (the weight of the infant), before placing the infant on the diaper, the extension part should be folded back according to the size of the infant's body. By connecting the first hook-and-loop fastener and the second hook-and-loop fastener to each other, the folded extension portion can be maintained. Compared with the case where the extended part is folded back after the infant is placed on the diaper, the infant caregiver can suppress the stimulation and burden on the infant.

According to the present invention, it is possible to provide a diaper that can be worn corresponding to a difference in body size of an infant (i.e., premature baby or low birth weight infant), and can prevent an obstacle to treatment or nursing. Can do.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the drawings.
The embodiments described below are preferable specific examples of the present invention, and thus various technically preferable limitations are given. However, the scope of the present invention is particularly limited in the following description. Unless otherwise stated, the present invention is not limited to these embodiments. Moreover, in each drawing, the same code | symbol is attached | subjected to the same component and detailed description is abbreviate | omitted suitably.

A diaper according to an embodiment of the present invention will be described with reference to FIGS. The diaper 2 which concerns on this embodiment is called a disposable diaper (diaper), a paper diaper (diaper), etc., and is used for infants. Specifically, the diaper 2 according to the present embodiment is used for premature babies and low birth weight babies in medical facilities such as hospitals.

The diaper 2 is sold in a state of being folded at a substantially central portion in the longitudinal direction of the diaper 2. On the other hand, the diaper 2 is unfolded as shown in FIGS. 1 and 2 when used. And the one end part in the longitudinal direction of the diaper 2 is arrange | positioned at the back side of the infant, and the other end part in the longitudinal direction of the diaper 2 is arrange | positioned at the ventral side 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 the infant.

As shown in FIG. 1 and FIG. 2, the diaper 2 includes a nonwoven fabric 3, a back sheet 4, an absorbent body 5, and a belt portion 6. The nonwoven fabric 3 is provided on the surface side that touches the skin of an infant. In the present specification, the “surface” refers to a surface that comes into contact with a diaper user (infant). The back sheet 4 is provided on the back side opposite to the infant when viewed from the nonwoven fabric 3. In the present specification, the “back surface” refers to a surface exposed to the outside when the diaper 2 is attached to an infant. The absorber 5 is provided between the nonwoven fabric 3 and the back sheet 4.

The non-woven fabric 3 extends from the infant's back to the stomach through the crotch. That is, the nonwoven fabric 3 extends along the extending direction D1 shown in FIGS. 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, and is, for example, about 100 mm or more and 300 mm or less. However, the length of the nonwoven fabric 3 in the extending direction D1 is not limited to this.

Non-woven fabric 3 is used as a surface material that touches the skin of an infant because it is a material that is difficult to raise, and has a role of allowing excretion such as urine of the infant to pass through the absorbent body 5. The nonwoven fabric 3 is called a surface sheet, a top sheet, etc., for example. The non-woven fabric 3 is a heat-bondable fiber (for example, PET / PE, PP / PE, PET / EP, PP / EP) obtained by fiberizing a synthetic resin, and is fused without using a binder by a thermal bond method or a spun bond method. It is formed by wearing.

As shown in FIG. 4, the nonwoven fabric 3 of the present embodiment is formed of a plurality of layers and includes a first fiber layer 33 and a second fiber layer 34. The first fiber layer 33 is disposed on a surface that directly touches the infant's skin and has an uneven surface 333 having a plurality of concave portions 331 and a plurality of convex portions 332. Thereby, the area which the nonwoven fabric 3 contacts with skin decreases, and a discomfort, a diaper rash, etc. are prevented. The 2nd fiber layer 34 is piled up on the back surface (inside of the diaper 2) of the 1st fiber layer 33, and exhibits a flat sheet shape as a whole.

The convex space 332 of the first fiber layer 33 bulges to the opposite side of the second fiber layer 34, so that an inner space S of the convex portion 332 is formed as a portion where the fibers are sparse. Thereby, even if the urine of the infant is not quickly absorbed by the absorbent body 5, it is 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 bonded to each other.

A three-dimensional gather portion 35 is provided on both outer sides of the uneven surface 333 in the width direction D2. The three-dimensional gather portion 35 is a barrier that prevents urine that has not been temporarily stored on the uneven surface 333 and prevents so-called side leakage. The width direction D2 corresponds to the “direction intersecting the direction in which the nonwoven fabric and the backsheet extend” and the “short 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 150 mm or less. However, the length of the nonwoven fabric 3 in the width direction D2 is not limited to this.

Crotch gathers 36 are provided on both outer sides of the three-dimensional gathers 35 in the width direction D2. The crotch gather part 36 is in close contact with the crotch part of the infant and prevents the urine etc. from leaking outside the diaper 2 even if excreted urine leaks from the three-dimensional gather part 35.

The elastic body 7 is provided inside each of the three-dimensional gather portion 35 and the crotch gather portion 36. The elastic body 7 is disposed along the extending direction D1 and has an elastic contraction ability. As the elastic body 7, for example, an elongated rubber such as a thread rubber is used. As the elastic body 7, a sheet-like or net-like rubber may be used. The elastic body 7 is fixed in an extended state, and applies a contraction force to the three-dimensional gather portion 35 and the crotch gather portion 36 when no external force is applied. Therefore, as shown in FIG. 3 and FIG. 4, the three-dimensional gather portion 35 and the crotch gather portion 36 stand up at the time of wearing due to the elastic contraction ability of the elastic body 7. As shown in FIG. 3, when an 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 variation of the nonwoven fabric 3, for example, in a plan view (see FIG. 1) when the diaper 2 is viewed from the surface side, the convex portion 332 has a substantially hexagonal shape, and the concave portion 331 corresponds to the six sides of the substantially hexagonal shape of the convex portion 332. The groove shape may be exhibited (not shown). Of course, the shape of the recessed part 331 and the convex part 332 is not necessarily limited to this. Moreover, the nonwoven fabric 3 may be one in which mesh processing is applied to the first fiber layer 33 and the second fiber layer 34 and an infinite number of through holes are provided. By such a mesh process, the nonwoven fabric 3 quickly allows excretion such as urine and soft feces peculiar to a newborn to permeate the absorber 5. Therefore, the excreta easily penetrates into the absorber 5.

The back sheet 4 is used as a back material provided on the side opposite to the infant as viewed from the nonwoven fabric 3, and suppresses the permeation of excretions discharged by the infant. The back sheet 4 is a sheet material that is exposed to the outside when the diaper 2 is attached to an infant, and is formed of a flexible material, for example, a thin plastic film. Specifically, a polyethylene film, polyethylene laminated paper, or the like is used as the material for the back sheet 4. The backsheet 4 is preferably impermeable to urine while allowing water vapor to pass therethrough. Thereby, the steam of the part covered with the diaper 2 can be prevented.

The absorbent body 5 is provided between the nonwoven fabric 3 and the back sheet 4 and has a role of absorbing excrement that has passed through the nonwoven fabric 3. That is, the absorber 5 is a part for absorbing and holding the discharged liquid such as urine. In the absorber 5, it is preferable that the absorbability of the absorbed liquid is high, and it is preferable that the thickness is relatively thin. It is preferable that the absorber 5 is not bulky. As the absorbent body 5, for example, a polymer is arranged in a high density between a pulp absorbent body formed by mixing a polymer that is an absorbent material with pulp, or by dispersing a polymer onto a pulp, or a sheet material made of pulp or the like. A polymer sheet made into a sheet is used.

As shown in FIG. 4, the absorber 5 is wrapped in a tissue 52 and is not exposed to the outside. As the tissue 52, a soft material that absorbs liquid or the like, for example, pulp, rayon, cotton, kenaf, bagasse, silk, hydrophilic treated fiber (polyolefin, polyester, acrylic), etc., is formed into a single or composite sheet. Things are used.

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 in the direction (width direction D2) intersecting the extending direction D1 of the nonwoven fabric 3. Specifically, the belt portion 6 includes a first belt main body 61 and a second belt main body 62. The first belt main body 61 is a belt-like member extending in one direction of the width direction D2. The second belt main body 62 is a belt-like member extending in the other direction (the direction opposite to the first belt main body 61) in the width direction D2.

The belt portion 6 preferably has stretchability in the width direction D2. For example, a nonwoven fabric having elasticity may be used as the material of the belt portion 6. Alternatively, a belt-shaped member in which a plurality of non-woven fabrics are bonded together and an elastic body such as a thread rubber having an elastic contraction ability is provided between the plurality of non-woven fabrics may be used as the material of the belt portion 6.

A connecting portion 63 is provided at the tip of the first belt main body 61 and the second belt main body 62. The connecting portion 63 is detachably connectable to the nonwoven fabric 3. Specifically, the connecting part 63 is a hook-and-loop fastener. Further, as shown in FIGS. 1 and 3, a frontal tape 32 connected to a connecting portion 63 as a hook-and-loop fastener is provided on the surface of the abdomen end portion of the nonwoven fabric 3. Details of the connection between the connecting portion 63 and the frontal tape 32 will be described later.

The connecting portion 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 connecting portion 63 as an adhesive layer can be detachably connected to the nonwoven fabric 3. Note that the frontal tape 32 is not necessarily provided.

Here, as with other infants, ordinary disposable diapers and paper diapers are generally used for premature babies and low birth weight infants raised in a neonatal intensive care unit. However, if it does so, a clearance gap tends to arise between bodies, such as premature infants, and diapers, and excrement, such as premature infants, may leak from a clearance between bodies, such as premature infants, and diapers. In addition, the body size of premature babies and the like varies depending on body weight. Therefore, it is difficult to cope with the difference in body size of a plurality of premature babies and the like only by reducing the size of the diaper while maintaining the shape and structure of the normal diaper.

There have been disposable diapers for premature babies or low birth weight babies. For example, a disposable diaper for premature babies or low birth weight babies should be placed on the absorbent body, the premature babies, etc. are wrapped around the waist and detachably connected. It is attached to premature babies and the like by applying an absorber so as to cover up to. However, the man's urine discharge position is on the front side (abdominal side) of the woman's urine discharge position. That is, a man discharges urine from a position on the front side (ventral side) as compared with a woman. Therefore, although the body movements of premature babies and low birth weight infants are limited, urine from male premature babies, etc., is only ventilated by premature babies, etc. There is a risk of it. In addition, the portion applied to the ventral side may be caught by a person who performs treatment or nursing, which may hinder treatment or nursing.

On the other hand, the diaper 2 according to the present embodiment has an extending portion 31. As shown in FIGS. 1 and 2, the extending portion 31 does not overlap with the absorbent body 5 provided on the back surface side of the nonwoven fabric 3 in a plan view, and further from the end 51 on the ventral side of the absorbent body 5. It is a part extended toward the stomach side, and is a part where the nonwoven fabric 3 and the back sheet 4 are bonded to each other. In other words, the extending portion 31 is a portion in which the nonwoven fabric 3 and the backsheet 4 extend from the ventral end 51 of the absorbent body 5 in the direction of the arrow D12 in the same plan view, and the nonwoven fabric 3 and the backsheet. 4 is a part where they are stuck together. Therefore, the absorbent body 5 is not disposed in the extended portion 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 extending portion 31 is about 2 to 5 times, preferably 3 times the length L2 of the connecting portion 63. When the length L1 of the extending portion 31 is 4 cm or more, the folding operation as described later becomes easy. In the diaper 2 shown in FIG. 1 and FIG. 2, in the extending direction D1, the length L2 of the connecting portion 63 is substantially the same as the length of the first belt body 61 and the length of the second belt body 62. However, the length of the first belt main body 61 and the length of the second belt main body 62 may be shorter.

Since the diaper 2 has such an extended portion 31, the infant childcare person can fold the extended portion 31 in accordance with the size of the infant's body so that it passes through the crotch portion from the infant's dorsal side to the ventral side. The diaper 2 having a size that matches the size of the infant's body can be attached to the infant. Thereby, the diaper 2 which concerns on this embodiment can be mounted | worn according to the difference in the magnitude | size of the infant's body. Therefore, it can suppress that the clearance gap by the bending of the diaper 2 arises between the infant's body and the diaper 2, and can suppress the excrement of the infant from leaking through the clearance gap. In addition, the extension part 31 is folded according to the size of the infant's body and connected to the connecting part 63, so that the extension part 31 may be caught by a person who performs treatment or nursing or hinders treatment or nursing. 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, an infant (a premature baby or a low birth weight infant) childcare person folds the extension portion 31 to the opposite side of the infant according to the size of the infant's body, When the connecting portion 63 of the belt portion 6 is connected to the installation portion 31, at least the connection portion 63 is folded back along the end portion 51 of the absorber so that the connection portion 63 extends to the extended extension portion 31. The full width (length L2) in the existing direction D1 can be reliably accommodated. Therefore, the connecting portion 63 is connected to the extending portion 31 over its entire width, and the connection between the connecting portion 63 and the extending portion 31 can be strengthened.

Next, with reference to FIGS. 5 to 7, the structure of the diaper 2 according to the present embodiment will be further described, and the method of using the diaper 2 will be described. First, when the infant childcare person wears the diaper 2 on the infant, the infant diaper 2 unfolds the diaper 2 (see FIGS. 1 and 2) and places the infant on the diaper 2.

At this time, as shown in FIG. 1 and FIG. 5, the nonwoven fabric 3 has a plurality of rib marks M1, M2, and M3. The buttocks mark M1, M2, M3 is provided at a position corresponding to the weight of the infant on the surface side of the central portion of the absorbent body 5 in the extending direction D1 of the nonwoven fabric. The buttocks mark M1, M2, M3 extends linearly along the width direction D2. The collar marks M1, M2, and M3 may have a form in which a continuous straight line extends along the width direction D2, and portions separated from each other, such as a broken line or a dotted line, extend along the width direction D2. It may have the form arranged and extended. For example, the buttocks mark M1, M2, M3 may be formed on the nonwoven fabric 3 by printing. Alternatively, the collar marks M1, M2, and M3 may be formed by embossing, such as the uneven surface 333 described above with reference to FIG.

When the infant childcare person wears the diaper 2 on the infant, the infant's buttocks are placed on the diaper 2 in accordance with the buttocks marks M1, M2, and M3 according to the size of the infant's body (infant's weight). be able to. That is, the buttocks mark M1 is a mark for an infant whose weight is about 800 g, for example. The infant childcare person can place the infant on an appropriate position of the diaper 2 by placing the infant's buttocks having a weight of, for example, about 800 g on the diaper 2 in accordance with the buttocks mark M1. Specifically, the infant childcare person can match the crotch portion of the infant with the substantially central portion of the absorbent body 5 in the extending direction D1. The buttocks mark M2 is a mark for infants whose weight is about 1500 g, for example. The infant childcare person can place the infant on an appropriate position of the diaper 2 by placing the infant's buttocks with a weight of, for example, about 1500 g on the diaper 2 in accordance with the buttocks mark M2. The buttocks mark M3 is a mark for an infant whose weight is about 2000 g, for example. The infant childcare person can place the infant on an appropriate position of the diaper 2 by placing the infant's buttocks having a weight of, for example, about 2000 g on the diaper 2 in accordance with the buttocks mark M3.

In this way, the infant childcare person places the infant's buttocks on the diaper 2 in accordance with the buttocks marks M1, M2, and M3 according to the size of the infant's body, and the appropriate position of the diaper 2 can be achieved by one operation. You can put an infant on it. That is, the infant childcare person can adjust the relative position of the infant and the diaper 2 to an appropriate position by one operation, and does not need to move the infant unnecessarily. Thereby, it can suppress that a burden is applied to the infant. In addition, since the infant childcare person can place the infant at an appropriate position of the diaper 2, it is possible to suppress a gap due to the bending of the diaper 2 between the infant's body and the diaper 2 and The excrement can be prevented from leaking.

In addition, the infant's weight with respect to each of the above-mentioned buttocks marks M1, M2, and M3 is an example, and is not limited thereto. The weight of the infant with respect to the buttocks mark M1 provided on the back side is lighter than the weight of the infant with respect to each of the buttocks mark M2 and the buttocks mark M3. The weight of the infant with respect to the buttocks mark M3 provided on the relatively ventral side is heavier than the weight of the infant with respect to each of the buttocks mark M1 and the buttocks mark M2. The buttocks mark M2 provided between the buttocks mark M1 and the buttocks mark M3 is heavier than the infant's weight relative to the buttocks mark M1 and lighter than the infant's weight relative to the buttocks mark M3.

Subsequently, the infant childcare person covers the infant's abdomen with the ventral part of the diaper 2. At this time, as shown in FIG. 2 and FIG. 5, the backsheet 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 extending portion 31 (the surface on the opposite side of the nonwoven fabric 3 from the surface 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 along the width direction D2. For example, portions separated from each other such as a broken line or a dotted line in the width direction D2. You may have the form arranged and extended along. For example, the crease marks M11, M12, and M13 may be formed on the back sheet 4 by printing. Alternatively, the crease marks M11, M12, and M13 may be formed by embossing, such as the uneven surface 333 described above with reference to FIG.

The crease marks M11, M12, and M13 are provided at positions corresponding to the weight of the infant. That is, the fold mark M11 is a mark for infants having a weight of about 800 g, for example. As shown in FIG. 6, the infant childcare person can return the extension portion 31 to the side opposite to the infant with the position of the crease mark M11 as a guide, so that the weight corresponds to an infant whose weight is about 800 g, for example. The extending portion 31 can be folded back. The fold mark M12 is a mark for infants whose weight is about 1500 g, for example. As shown in FIG. 6, the child care worker of the infant turns the extension portion 31 to the side opposite to the infant with the position of the crease mark M12 as a guideline, so that the position corresponding to the infant whose weight is about 1500 g, for example. The extending portion 31 can be folded back. The fold mark M13 is a mark for an infant whose weight is about 2000 g, for example. As shown in FIG. 6, the child care worker of the infant turns the extension portion 31 to the side opposite to the infant with the position of the crease mark M13 as a guideline, so that the position corresponding to the infant whose weight is about 2000 g, for example. The extending portion 31 can be folded back.

Thus, the infant childcare person turns the extension part 31 back according to the size of the infant's body (infant's weight) using the crease marks M11, M12, M13 provided on the backsheet 4 as a guide. Can do. At this time, as shown in FIG. 5, in the extended portion 31, the first surface fastener 41 and the second surface fastener 42 are provided on the surface of the back sheet 4 on the side opposite to the nonwoven fabric 3. It has been. The first hook-and-loop fastener 41 and the second hook-and-loop fastener 42 can be connected to each other on the surface of the back sheet 4 opposite to the nonwoven fabric 3. For example, one of the first surface fastener 41 and the second surface fastener 42 is a male material of the surface fastener. For example, the other of the first surface fastener 41 and the second surface fastener 42 is a female material of the surface fastener. Note that the second hook-and-loop fastener 42 is not necessarily provided in the extending portion 31, and may be provided, for example, on the crotch portion side when viewed from the abdomen side end portion 51 of the absorbent body 5.

According to this, when the infant childcare person knows the size of the infant's body (the weight of the infant), the childcare person can extend the baby according to the size of the infant's body before placing the infant on the diaper 2. By folding the installation portion 31 and connecting the first surface fastener 41 and the second surface fastener 42 to each other, the state of the extended installation portion 31 can be maintained. Compared with the case where the extension part 31 is folded back after the infant is placed on the diaper 2, the infant childcare worker can suppress the stimulation and burden on the infant.

Further, since the absorbent body 5 is not disposed in the extended portion 31, it is possible to prevent the extended portion 31 from becoming strong or bulky when the extended portion 31 is folded. Therefore, the infant childcare person can easily fold the extended portion 31 back.

Subsequently, as shown in FIG. 7, the infant childcare person covers the abdomen of the infant with the abdomen portion of the diaper 2 while maintaining the state of the extended portion 31 folded back to the opposite side of the infant, The connection part 63 of the belt part 6 is connected to the surface of the nonwoven fabric 3 exposed on the opposite side to the infant. At this time, as described above with reference to FIGS. 1 and 3, the frontal tape 32 is provided on the end surface of the non-woven fabric 3 on the ventral side. Specifically, the frontal tape 32 is provided on the surface of the nonwoven fabric 3 in the extending portion 31. The infant childcare person covers the abdomen of the infant with the abdomen portion of the diaper 2 and connects the connecting portion 63 of the belt portion 6 to the frontal tape 32. Thereby, the connection part 63 is reliably connected by the surface of the nonwoven fabric 3 in the extension part 31. FIG.

Thus, as shown in FIG. 7, the diaper 2 according to the present embodiment is attached to an infant (a premature baby or a low birth weight infant). An infant childcare person places the infant's buttocks on the diaper 2 in accordance with the buttocks marks M1, M2 and M3 according to the size of the infant's body, or uses the fold marks M11, M12 and M13 as a guide.
