Description

Disposable diapers

The present invention relates to disposable diapers.

Conventionally, disposable diapers have been used not only in ordinary households but also in medical settings such as hospitals and facilities. In medical practice, users such as nurses who change diapers often check the size of diapers not only before use but also when measuring the weight of diapers after use. Patent Document 1 discloses a disposable diaper in which a display indicating the country of manufacture or the raw material and a display indicating the size of the diaper in characters are visibly arranged.

Japanese Unexamined Patent Publication No. 2016-22255

According to the disposable diaper of Patent Document 1, the user (exchanger) of the diaper can visually recognize the size display from the appearance of the diaper, but depending on the position of the size display, it may be difficult for the user to understand. , Wrinkles, etc. may be difficult to see.

The present invention has been made in view of the above-mentioned conventional problems, and an object of the present invention is to provide a disposable diaper in which a changer (nurse, etc.) can easily see the size notation when changing diapers. It is in.

The main invention for achieving the above object is
A disposable diaper having a liquid-absorbing absorber, which is provided with a size notation section that indicates the size of the disposable diaper and is visible from the non-skin side of the disposable diaper. , The disposable diaper is characterized in that it is arranged so as to straddle the center in the width direction of the disposable diaper.
Other features of the present invention will be clarified by the description in the present specification and the accompanying drawings.

According to the present invention, it is possible to provide a disposable diaper in which the changer (nurse, etc.) can easily see the size notation when changing the diaper.

It is a schematic plan view which looked at the disposable diaper 1 in the unfolded and stretched state from the skin side in the thickness direction. FIG. 2A is a schematic cross-sectional view of the disposable diaper 1 on the dorsal side 1A. FIG. 2B is a schematic cross-sectional view of the disposable diaper 1 in the inseam 1C. It is a schematic plan view of the disposable diaper 1, and is the figure explaining the three-dimensional gather part 50. It is a schematic plan view which looked at the disposable diaper 1 in the unfolded and stretched state from the non-skin side in the thickness direction. FIG. 5A is a partially enlarged view for explaining the ventral side portion 1B of the disposable diaper 1 of FIG. 4, and FIG. 5B is a diagram for explaining the arrangement relationship between the size notation portion 100 and the absorber 2. FIG. 6A is a diagram showing an example of the arrangement relationship between the size notation unit 100 and the absorber 2, and FIG. 6B is a diagram showing another example of the arrangement relationship between the size notation unit 100 and the absorber 2. It is a figure which shows the diaper 1 in the state which is folded in half by the fold line FL.

The description of this specification and the accompanying drawings will clarify at least the following matters.
A disposable diaper having a liquid-absorbing absorber, which is provided with a size notation section that indicates the size of the disposable diaper and is visible from the non-skin side of the disposable diaper. , The disposable diaper is characterized in that it is arranged so as to straddle the center in the width direction of the disposable diaper.

According to such a disposable diaper, the position straddling the center in the width direction of the diaper is a position that is easily visible to the diaper changer (nurse, etc.) when wearing the diaper, and therefore it is easy to check the size of the diaper. , The possibility of misidentifying the size can be reduced. Further, even when the product is taken out from the packaging bag, the center in the width direction is less likely to be folded or wrinkled, and the size notation portion is easy to see clearly.

In such a disposable diaper, it is desirable that the size notation portion is arranged so as to overlap the absorber by half or more in the width direction and the longitudinal direction orthogonal to the width direction.

According to such a disposable diaper, the absorber portion is a portion where wrinkles and the like are less likely to occur because the product is taut due to the thickness of the absorber, and is half of such an absorber in the width direction and the longitudinal direction. By providing the size notation section so as to overlap the above, most of the size notation section can be easily visually recognized. Therefore, it is easy for the exchanger (nurse, etc.) to check the size of the diaper, and the possibility of misidentifying the size can be reduced.

In such a disposable diaper, it is desirable that the size notation portion is arranged so as to completely overlap the absorber in the width direction and the longitudinal direction orthogonal to the width direction.

According to such a disposable diaper, the absorber portion is a portion where wrinkles and the like are less likely to occur because the product is taut due to the thickness of the absorber, and is completely in the width direction and the longitudinal direction with such an absorber. By arranging the size notation part so as to overlap with, the size notation part becomes easier to see. Therefore, it is easier for the exchanger (nurse, etc.) to confirm the size of the diaper, and the possibility of misidentifying the size can be further reduced.

It is desirable that the size notation part of such a disposable diaper is located inside a predetermined design.

According to such disposable diapers, the size notation part stands out along with the design, making it easier for diaper changers (nurses, etc.) to check the size. Since the size notation is surrounded by a symbol, it can be easily recognized as a symbol, so that the size can be easily recognized, and a healing effect can be given when the size is visually recognized.

In such a disposable diaper, it is desirable that the area of the predetermined design is larger than the area of the size notation portion.

According to such disposable diapers, since the area of a predetermined pattern is larger, the size notation part has a larger element as a pattern than a simple number and character element indicating the size, so that the exchanger (nurse, etc.) ) Can be further given a healing effect.

In such a disposable diaper, a ventral portion arranged along the width direction on the ventral side of a low weight child of 3000 g or less, a crotch part arranged in the crotch of the low weight child, and the low weight child. The dorsal side portion arranged along the width direction is arranged side by side in the longitudinal direction orthogonal to the width direction, and is provided at each end portion of the dorsal side portion in the width direction. Each of the ends is locked to the ventral side via a fastening tape, and the disposable diaper has a folding line along the width direction at the center in the longitudinal direction, and the one waist circumference opening. With the upper side and the lower crotch part on the lower side, it is desirable that the size notation portion is arranged on the ventral side portion above the center of the disposable diaper folded in half along the folding line in the vertical direction.

According to such disposable diapers, the position above the center of the ventral side in the vertical direction is a position where the exchanger (nurse, etc.) can easily check the size when the product is taken out before wearing. In addition, since the size of diapers worn by low-weight children is smaller than usual, when parents of low-weight children visually recognize the size notation of the small size while wearing it, they may feel negative emotions such as anxiety and anxiety about the low-weight children. Easy to hold. However, the position above the center of the ventral side in the vertical direction is a portion where the size notation is likely to be hidden by the fastening tape when the diaper is worn, and the size notation can be obscured during wearing.

It is desirable that a part of the size notation portion of such a disposable diaper is located outside the absorber in the longitudinal direction.

According to such disposable diapers, in the case of diapers for low-weight infants, the diaper is often folded back along the width direction at the position of the outer end in the longitudinal direction of the absorber on the ventral side. At that time, a part of the size notation portion located outside the absorber is hidden, and it becomes difficult for the parents of the low weight child who is watching over to see the size of the diaper. By making it difficult to see, it is possible to prevent parents from feeling negative about wearing a small size.

In such a disposable diaper, when the disposable diaper in the unfolded state is folded in half at the central portion in the longitudinal direction, the extension region in which the fastening tape is extended inward in the width direction along the width direction is formed. It is desirable to have a portion that overlaps with the size notation portion in the longitudinal direction and the width direction.

According to such disposable diapers, when wearing a diaper, if you are wondering where to attach the fastening tape, you can lock the fastening tape so that it overlaps the size notation with the size notation as a mark. The disposable tape can be applied straight to the body of a low weight child. In addition, the size notation is more likely to be hidden by locking the fastening tape at the time of wearing, and the size notation is difficult to see, which reduces the possibility that parents have negative emotions.

It is desirable that the disposable diaper is provided with a dorsal size notation portion different from the size notation portion on the dorsal side portion.

According to such disposable diapers, having different size notations on the front and back makes it easier to recognize the front and back. In addition, the size can be confirmed both before and after the diaper, making it easier to prevent misidentification of the size.

It is desirable that the size notation part of the disposable diaper is larger than the dorsal size notation part.

According to such disposable diapers, the size notation on the ventral side is in a position that is easy to see when worn, so by making the size conspicuous to some extent, the exchanger (nurse, etc.) can check the size. It will be easier. In addition, since the size notation on the ventral side may be hidden by locking the fastening tape, it can be difficult to see from the appearance of the diaper. On the other hand, since it is difficult to hide the size notation on the back side even while wearing it, it is less noticeable if the notation is as small as possible, and it is difficult for parents of low-weight children to notice it. In addition, even if the low weight child is in the prone position during wearing, the dorsal size notation is difficult to see.

In such a disposable diaper, it is desirable that the dorsal size notation portion is arranged outside the size notation portion in the width direction.

According to such disposable diapers, the notation on the back side is difficult to hide even while wearing, so place it on the outside in the width direction of the diaper as much as possible to make it inconspicuous. On the other hand, the changer, such as a nurse, removes the diaper at the time of replacement, rolls the diaper so that the non-skin side of the dorsal side is on the outside, and then measures the weight of the diaper. Therefore, by arranging the diaper on the outside in the width direction (closer to the edge of the diaper), it becomes easier to visually recognize the size notation even when the diaper is rolled.

In such a disposable diaper, it is desirable that the dorsal size notation portion has a portion that does not overlap with the absorber in the width direction.

According to such a disposable diaper, the dorsal size notation part becomes easier to see as there are more parts that overlap with the absorber, but having a part that does not overlap with the absorber makes it difficult to see. By making it harder to see, it reduces the likelihood that parents of underweight children will have negative emotions about wearing a smaller size.

In such a disposable diaper, the size notation portion is located inside a predetermined symbol, and if the predetermined symbol on which the size notation portion is arranged is the first symbol, the dorsal size notation is used. It is desirable that the portion is located inside a predetermined second symbol different from the first symbol.

According to such a disposable diaper, front and back recognition becomes easy because the design is different before and after the diaper (ventral side and dorsal side). In addition, considering that the size notation on the ventral side is hidden by the fastening tape, the design on the ventral side can be made slightly conspicuous to prevent misidentification by the exchanger (nurse, etc.). Further, since the size notation portion on the back side is hard to hide even during wearing, a design that is inconspicuous can be used as the second symbol that surrounds the size notation portion on the back side.

Such a disposable diaper has a logo mark that can be seen from the non-skin side of the disposable diaper, and when the disposable diaper is folded in half along the folding line, the logo mark is the fastening in the vertical direction. It is desirable that the tape is provided below the lower end of the tape or above the upper end of the fastening tape.

According to such disposable diapers, the logo mark is not hidden by the locking of the fastening tape even while wearing it, and the logo mark is shown to the exchanger (nurse, etc.) and the watcher (parents, etc.), giving an impression of the product brand. To increase.

It is desirable that the disposable diaper is provided with linear patterns parallel to the longitudinal end edge of the absorber and the width direction on both sides of the size notation portion in the width direction.

According to such disposable diapers, diapers for low-weight infants may be used by folding back the longitudinal end of the ventral side, and the linear pattern serves as the reference line for folding back at that time. Therefore, the exchanger (nurse, etc.) can use the reference line as a guideline for turning back. In addition, when the diaper is folded back at the position of the linear pattern, a part of the size notation portion is also folded and becomes difficult to see, and it becomes difficult for parents of a low weight child to visually recognize the size notation while wearing the diaper.

=== Embodiment ===
FIG. 1 is a schematic plan view of a disposable diaper 1 in an unfolded and stretched state (hereinafter, also simply referred to as a diaper 1) as viewed from the skin side in the thickness direction. FIG. 2A is a schematic cross-sectional view of the diaper 1 in the dorsal portion 1A. FIG. 2B is a schematic cross-sectional view of the diaper 1 in the inseam 1C. FIG. 3 is a schematic plan view of the diaper 1 and is a diagram for explaining the three-dimensional gather portion 50.

This diaper 1 is a deployable diaper 1 that is worn by the wearable person using the fastening tape 40, and is particularly preferably used for a low weight child of 3000 grams or less. In the following, the wear target person will be described as a low weight child, but the wear target person is not limited to this, and the wear target person may be an infant, an infant, or an adult.

The unfolded state of the diaper 1 is a state in which the diaper 1 is unfolded on a flat surface 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 dorsal side portion 1A, an inseam 1C, and a ventral side portion. 1B and 1B are provided side by side. The ventral portion 1B is a portion arranged along the width direction on the ventral side (front side) of the wearer when wearing the diaper 1. The dorsal side portion 1A is a portion arranged along the width direction on the back side (rear side) of the wearer when wearing the diaper 1. An inseam 1C arranged between the user's crotch is provided between the ventral portion 1B and the dorsal portion 1A. 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 back sheet 4 (leakage-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. A flexible sheet such as (spun bond / melt blown / spun bond non-woven fabric) 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 on the dorsal side 1A, and both lateral sides in the width direction from the crotch 1C on the ventral side 1B. It is provided with a pair of extended second extension portions 20B. 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 on the ventral side 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 of diapers 1A on the dorsal side 1A side. The first extending portion 20A 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 ventral side 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 sides 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 around the legs 7 (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 be along 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 elastic member 7 around the leg are exemplified by 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 dorsal side 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. When the wearer of the diaper 1 is a low-weight child or the like, the diaper 1 may be worn upside down while in the prone position. In such a case, the fastening tape 40 is attached to the back side of the wearer. It will be in a stopped state. When removing the diaper from that state, by cutting the cutting line 60, the dorsal part 1A (here, attached to the ventral side) to which the hard fastening tape 40 is fixed is not passed between the legs of the low weight child. , The diaper 1 can be pulled out, and the burden on the skin of a low weight child 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 not limited to the shape shown in FIG. 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.

<< About diaper size notation >>
In general, disposable diapers, regardless of whether they are for infants or adults, often have a size notation indicating the size of the diaper on the non-skin side of the diaper. When disposable diapers are used in general households, the number of wearers is limited, and there may be few opportunities to check the size of the diaper each time they are worn, but in medical settings such as hospitals, an unspecified number of patients (Wearer) diapers are often changed, and size confirmation is frequently performed in order to wear diapers of a size suitable for each patient.

In addition, confirmation of the size of the diaper in the medical field may be necessary not only before use but also when measuring the weight of the diaper after use, so that the size notation is required to be easy to read. However, in the conventional product, there are cases where the position of the size notation is difficult to understand, or the size notation itself is difficult to see due to wrinkles or the like on the diaper.

Regarding this point, the diaper 1 of the present embodiment has the following configuration. FIG. 4 is a schematic plan view of the unfolded and stretched diaper 1 as viewed from the non-skin side in the thickness direction. FIG. 5A is a partially enlarged view for explaining the ventral side of the disposable diaper 1 of FIG. 4, and FIG. 5B is a diagram for explaining the arrangement relationship between the size notation portion 100 and the absorber 2.

As shown in FIGS. 4 and 5A, the diaper 1 is provided with a size notation unit 100 that indicates the size of the diaper 1 and is visible from the non-skin side of the diaper 1. In the present embodiment, the size notation unit 100 means the number and character portion indicated as "4S", but the size display unit 100 is not limited to the combination of numbers and characters, and the notation of only numbers and characters It may be written only. Further, it may be some kind of mark or the like that allows the user (for example, a diaper changer such as a nurse) to recognize the size. Further, the size notation unit 100 of the present embodiment is provided by printing on the non-skin side of the back sheet 4, but the size is not limited to this as long as it can be visually recognized from the non-skin side of the diaper 1.

Then, as shown in FIG. 5A, the size notation unit 100 is arranged so as to straddle the center (center position CL1) in the width direction of the diaper 1. The position straddling the center (center position CL1) in the width direction of the diaper 1 is a position that is easily visible to the diaper 1 changer (nurse or the like) when wearing the diaper 1. Therefore, by providing the size notation unit 100 at such a position, it becomes easy to confirm the size of the diaper 1, and the possibility of misidentifying the size can be reduced. Further, even when the product (diaper 1) is taken out from the packaging bag before use, the center in the width direction is less likely to be folded or wrinkled, and the size notation portion 100 is easily visible.

Further, in FIG. 5B, only the size notation portion 100 and the absorber 2 in FIG. 5A are shown. Of the notation portion "4S" of the size notation unit 100, the length from the outer end to the inner end in the longitudinal direction is L1, and of the length L1, the length overlapping the absorber 2 in the longitudinal direction is L2. Assuming that the non-overlapping length is L3, the length L2 that overlaps in the longitudinal direction is longer (L2> L3). That is, the size notation portion 100 is arranged so as to overlap the absorber 2 by more than half in the longitudinal direction. Further, in the width direction, both side ends W1 and W2 of the notation portion "4S" of the size notation unit 100 are located inside the both side ends of the absorber 2 in the width direction. That is, the size notation unit 100 all overlaps with the absorber 2 in the width direction. However, the present invention is not limited to this, and the size notation unit 100 may be arranged so as to overlap the absorber 2 by half or more even in the width direction.

In the diaper 1, the part of the absorber 2 is a part where the product is taut due to its thickness and wrinkles and the like are unlikely to occur. By providing the size notation unit 100 so as to overlap the absorber 2 by more than half in the width direction and the longitudinal direction, the overlapping portion, that is, most of the size notation unit 100 can be easily visually recognized.

Further, when the diaper 1 is a small size diaper for low weight children as in the present embodiment, when the product is stored in the packaging body, the portion without the absorber 2 may be folded. There are many. However, by arranging the size notation unit 100 so as to overlap the absorber 2 by more than half in the width direction and the longitudinal direction, even when the folded diaper 1 is taken out, more than half of the size notation unit 100 can be visually recognized. Because it can be done, it is easy for users such as nurses to check the size.

Next, FIG. 6A is a diagram showing an example of the arrangement relationship between the size notation unit 100 and the absorber 2, and FIG. 6B is a diagram showing another example of the arrangement relationship between the size notation unit 100 and the absorber 2. Is. 6A and 6B show only the size display unit 100 and the absorber 2 for convenience of explanation.

As shown in FIG. 6A, the size notation unit 100 may be arranged so as to completely overlap the absorber 2 in the width direction and the longitudinal direction. The size notation portion 100 of FIG. 6A is arranged at substantially the center of the absorber 2 in the width direction and near the upper end 2ea of the absorber 2 in the longitudinal direction, but is not limited to this. It may be located closer to the widthwise end of the absorber 2 or lower in the longitudinal direction. Since the part of the absorber 2 is a part where the product is tense due to its thickness and wrinkles and the like are unlikely to occur, the size is indicated so as to completely overlap with such a absorber 2 in the width direction and the longitudinal direction. By arranging the unit 100, the size notation unit 100 becomes easier to see.

Returning to FIG. 5, the diaper 1 has a fold line FL (corresponding to the central position CL2 in the longitudinal direction) along the width direction at the central portion in the longitudinal direction. Further, as shown in FIG. 5A, assuming that the side that becomes one waist circumference opening (so-called outer end in the longitudinal direction) is on the upper side and the inseam 1C is on the lower side, the size notation portion 100 is located on the ventral side portion 1B. The diaper 1 folded in half along the folding line FL is arranged above the central ML in the vertical direction.

The position above the central ML in the vertical direction of the ventral side 1B is a position where the nurse or the like who is the user can easily confirm the size when the product is taken out before mounting. By providing the size notation unit 100 at such a position, the possibility of misidentification of the size is reduced. Also, if the low weight child is the wearer, the size of the diaper 1 to be worn is smaller than usual, so if the parents of the low weight child check the size notation of the small size while wearing it, they may be worried about the low weight child. It is easy to have negative feelings such as anxiety. However, there is also a target area 45 for locking the fastening tape 40 at a position above the central ML in the vertical direction of the ventral side portion 1B, and there is a high possibility that the size notation portion 100 is hidden by locking the fastening tape 40. It is a part. As a result, the size notation unit 100 can be obscured while the diaper 1 is being worn. By making it difficult to see, it becomes difficult for parents of a low-weight child to recognize the size notation unit 100, and the possibility of having negative emotions can be reduced.

Further, as shown in FIG. 6B, a part of the size notation portion 100 may be located outside the absorber 2 in the longitudinal direction. In the case of the diaper 1 for low-weight children, when the diaper 1 is attached to the child, in order to prevent the diaper from coming into contact with the medical device attached to the body, or to further reduce the size of the diaper 1, etc. Therefore, in the ventral portion 1B, the diaper 1 is often folded back along the width direction at the position of the outer end 2ea in the longitudinal direction of the absorber 2. In that case, a part of the size notation portion 100 located outside the absorber 2 in the longitudinal direction is folded back together and hidden, making it difficult to visually recognize the size. This prevents parents of low weight infants from feeling negative about their small size.

Further, as shown in FIGS. 4 and 5A, the size notation unit 100 is surrounded by a predetermined heart-shaped symbol 105, that is, is located inside the predetermined symbol 105. By locating the size notation unit 100 inside the predetermined symbol 105, the size notation portion 100 stands out together with the symbol 105, and the nurse or the like who is the user can easily confirm the size. Further, since the size notation unit 100 is surrounded by the heart-shaped symbol 105, it is easy to recognize the size as a symbol, so that not only the size can be easily visually recognized, but also a healing effect can be given when the size is visually recognized. The predetermined symbol 105 is not limited to the heart shape, and any symbol having an arbitrary shape that can surround the size notation unit 100 can be used.

Further, it is preferable that the area of the predetermined symbol 105 is larger than the area of the size notation unit 100. As a method of obtaining the area of each of the predetermined symbol 105 and the size notation unit 100, for example, the area of each of the predetermined symbol 105 including the size notation unit 100 is taken into a personal computer and the area can be measured by software. Can be measured. Since the area of the predetermined symbol 105 is larger, the element as the handle is larger than the numerical element indicating the mere size, so that it has a healing effect on the diaper 1 changer and parents watching over the low weight child. Can be given.

FIG. 7 is a diagram showing a diaper 1 in a state of being folded in half along the folding line FL. As shown in FIG. 7, when the unfolded diaper 1 is folded in half along the folding line FL in the central portion in the longitudinal direction, the extension region 40ex in which the fastening tape 40 is extended inward in the width direction along the width direction is formed. , Has a portion that overlaps with the size notation portion 100 in the longitudinal direction and the width direction.

When the diaper 1 is attached to the wearer, it may be confused as to where the fastening tape 40 should actually be locked, but the extension region 40ex has a portion that overlaps with the size notation portion 100 in the longitudinal direction and the width direction. Therefore, if each fastening tape 40 is locked so as to overlap the size notation portion 100 with the size notation portion 100 as a mark at the time of wearing, the fastening tape 40 can be attached straight to the body of a low weight child. Further, with such a configuration, there is a high possibility that the size notation portion 100 is hidden by the fastening tape 40 when the diaper 1 is worn, and it is possible to make it difficult to visually recognize the size of the diaper during wearing.

Returning to FIG. 4, the diaper 1 of the present embodiment is provided with a dorsal size notation unit 110 different from the size notation unit 100 in the dorsal side portion 1A. Similar to the dorsal size notation unit 110 and the size notation unit 100, here, it means the number and character portion indicated as "4S" as an example. The dorsal size display unit 110 is not limited to a combination of numbers and letters, and may be represented only by numbers or letters. Further, it may be some kind of mark or the like that allows the nurse or the like who is the user to recognize the size. As described above, by having the dorsal size display unit 110 indicating the size of the diaper 1 not only in the ventral portion 1B but also in the dorsal portion 1A, the diaper 1 can be placed in front of or behind the diaper 1 (ventral side and dorsal side). You can check the size, and it will be easier to prevent misidentification of the size.

Further, it is preferable that the size notation unit 100 is larger than the dorsal size notation unit 110. Since the size notation part 100 of the ventral side 1B is in a position where the changer of the diaper 1 can easily see it when wearing it, it is easy for the changer (nurse, etc.) to check the size by making the size conspicuous to some extent. Become. Further, since the size notation portion 100 of the ventral side portion 1B may be hidden by locking the fastening tape 40 at the time of wearing, it can be obscured by the parents of the low weight child. On the other hand, since it is difficult to hide the dorsal size notation 110 of the dorsal portion 1A even while wearing it, it is less noticeable if the notation is as small as possible, and it is difficult for parents of a low weight child to notice it.

Also, by having size notation parts with different sizes on the front and back (ventral side and dorsal side) of the diaper 1, the person who exchanges the diaper 1 can easily recognize the front and back. Furthermore, even if the low weight child is in the prone position during wearing and the dorsal part 1A side is in a state where it is easy for the watcher such as parents to see, the dorsal size notation part 110 is changed to a small notation part. It is hard to see by leaving it. The size of the size notation unit 100 and the size of the dorsal size notation unit 110 are compared by comparing the total area of each notation unit. For example, the portion of the size notation unit 100 and the portion of the dorsal size notation unit 110 can be taken into a personal computer, and the respective areas can be measured and compared with software capable of measuring the area.

Further, as shown in FIG. 4, the dorsal size notation unit 110 is arranged outside the size notation unit 100 in the width direction. Since the dorsal size notation portion 110, which is different from the size notation portion 100 of the ventral side portion 1B, is provided on the dorsal side portion 1A, it is difficult to hide even while the diaper 1 is worn. Therefore, by locating the diaper 1 on the outer side in the width direction as much as possible, it is made inconspicuous. On the other hand, an exchanger such as a nurse may remove the diaper 1 at the time of exchange, roll the diaper 1 with the skin side of the diaper 1 inside, and fasten it with the fastening tape 40, and then measure the weight of the diaper 1. .. At that time, the size of the rolled diaper 1 can be confirmed by arranging the dorsal size notation portion 110 on the outside in the width direction (closer to the edge of the diaper) with the non-skin side surface of the dorsal side portion 1A on the outside. It becomes easier to do.

Further, in FIG. 4, the dorsal size notation portion 110 is arranged so as not to overlap with the absorber 2 in the width direction. The portion of the absorber 2 is taut due to the thickness of the absorber 2 and wrinkles and the like are less likely to be formed, and the more the portion overlaps with the absorber 2, the easier it is to see the dorsal size notation portion 110. However, by preventing the dorsal size notation 110 from overlapping with the absorber 2 in the width direction, the dorsal size notation 110 is made difficult to see, and it is difficult for parents of low-weight children to recognize the small size. obtain.

A part of the dorsal size notation part 110 may overlap with the absorber 2 in the width direction. That is, in order to make the dorsal size notation portion 110 difficult to see, it is sufficient to have a portion that does not overlap with the absorber 2 in the width direction. As a result, the dorsal size notation unit 110 has a portion that is difficult to see.

Further, as shown in FIG. 4, the dorsal size notation portion 110 of the present embodiment is surrounded by a predetermined symbol 115 which is a floral pattern, that is, is located inside the predetermined symbol 115. The predetermined symbol 115 (second symbol) of the dorsal size notation unit 110 is different from the predetermined symbol 105 (first symbol) in which the size notation unit 100 is arranged. Since the design surrounding the size notation (100, 110) is different between the front and back of the diaper 1, the person who exchanges the diaper 1 can easily recognize the front and back by using the pattern as a guide. Further, the size notation portion 100 of the ventral side portion 1B may be conspicuous in consideration of being hidden by the fastening of the fastening tape 40 at the time of wearing. Further, since the dorsal size notation portion 110 of the dorsal side portion 1A is difficult to hide, it is preferable to use a design that is inconspicuous. For example, it is preferable to use a design or the like related to a decorative design (not shown) that can be visually recognized from the appearance of the diaper. By making the design related to the decorative design, the dorsal size notation portion 110 is confused with the decorative design and becomes inconspicuous. This makes it less noticeable to parents of low birth weight infants. The above-mentioned decorative pattern may be provided on the non-skin side surface of the back sheet 4 together with the dorsal size notation portion 110, for example.

Further, as shown in FIG. 4, the diaper 1 of the present embodiment has a logo mark 120 visible from the non-skin side of the diaper 1 on the dorsal side 1A and the ventral side 1B. As an example, the logo mark 120 surrounds the characters "ABC", which means the name of the manufacturing company, with a heart-shaped pattern, but the form of the logo mark 120 is not limited to this, and any logo mark can be adopted. Is. The logo marks 120 are provided below the lower end of the fastening tape 40 in the vertical direction when the diaper 1 is folded in half along the folding line FL (see FIGS. 4 and 7). By arranging the logo mark 120 at such a position, the logo mark 120 is hard to be hidden by the fastening tape 40 even during wearing on the ventral side 1B, and the user (nurse or parents) is placed on the dorsal side 1A. Etc.) are easy to see. By showing the logo mark 120 before, after, and during mounting, the impression of the product brand can be enhanced. The logo mark 120 may be provided above the upper end of the fastening tape 40, and the same effect can be obtained in that case as well.

Further, it is preferable that the size notation unit 100 and the dorsal size notation unit 110 are larger than the logo mark 120. Since the size notation unit 100 and the back side size notation unit 110 indicating the size of the diaper 1 are more conspicuous, the possibility of misidentifying the size when the diaper 1 is taken out from the packaging bag is reduced.

Further, as shown in FIGS. 4 and 5, linear symbols 106 along the longitudinal edge 2ea of the absorber 2 are provided on both sides of the size notation portion 100 in the width direction. In the case of diapers 1 for low weight infants, the length of the ventral portion 1B is to avoid medical devices attached to the body of the low weight infant or to fit the small body size of the low weight infant. The end portion in the direction may be folded back along the edge 2ea of the absorber 2 for use. Then, the linear symbol 106 serves as a reference line for folding back at that time. Therefore, an exchange such as a nurse can use the reference line as a guideline for turning back. Further, when the diaper 1 is folded back at the position of the linear pattern 106, a part of the size notation portion 100 is also folded in and becomes difficult to see. Therefore, it becomes difficult for the parents and the like to see the size notation unit 100 during wearing, and it is possible to reduce the possibility that the parents watching over the low weight child have negative emotions toward the small size. The linear symbol 106 of the present embodiment is provided along the longitudinal edge 2ea of the absorber 2, but is not limited to this. That is, the linear symbol 106 may be parallel to the longitudinal edge 2ea of the absorber 2 in the width direction on both sides of the size notation portion 100 in the width direction.
