  The fastening tape 7 is provided so as to protrude laterally from the second lateral end 125. And by fastening each fastening tape 7 to the target area | region 114 (FIG. 2) provided in the non-skin side surface of the 1st waist part 11, as shown to FIG. 4A, the waist part opening part 1HB and a pair of leg circumferences Openings 1HL and 1HL are formed, and the diaper 1 is attached to the low-weight child 9.

  The sheet-like member of the diaper 1 includes a liquid-permeable top sheet 2 that covers the absorber 3 from the skin side, a liquid-impermeable leak-proof sheet 4 that covers the absorber 3 from the non-skin side, and a leak-proof sheet 4. A pair of outer sheets 5 such as a substantially hourglass-shaped non-woven fabric covering the non-skin side and forming the outer shape of the diaper 1 are provided side by side on the top sheet 2 in a lateral direction. A pair of three-dimensional gather sheets 61 and 61 forming three-dimensional gathers 6 and 6 as leak-proof walls are provided.

  As illustrated in FIGS. 3A to 3C, the absorbent body 3 includes an absorbent core 31 and a core wrap sheet 32 that is a liquid-permeable sheet that covers substantially the entire outer peripheral surface of the absorbent core 31. The absorbent core 31 is a substantially rectangular liquid absorbent material, and has two pairs of notches 33 and 34 in the vertical direction at the end in the horizontal direction. The notches closer to the vertical end 123 are first cutouts 33 and 33, and the cutouts closer to the vertical end 113 are second cutouts 34 and 34 (FIG. 2). By being cut out by the pair of cutouts 33 and 34, the narrowest portion that is narrowest in the lateral direction is formed in the absorbent core 31 and the absorbent body 3. At this time, the first cutout 33 and the second cutout 34 are both formed on the vertical end 113 side from the vertical center line XX in the vertical direction. In addition, the shape of the absorptive core 31 is not limited to the above shape, and may be, for example, a substantially hourglass shape.

  As shown in FIGS. 2 and 3A to 3C, the top sheet 2 and the leak-proof sheet 4 have a planar dimension that protrudes from both sides in the vertical direction and both sides in the horizontal direction of the absorbent body 3 and is bonded or welded. And the absorbent body 3 is held between the two sheets 2 and 4. And on the skin side of the exterior sheet 5, the absorbent bodies 3 held between the sheets 2, 4 and the sheets 2, 4 are overlapped with the center positions in the lateral direction being aligned with each other, and bonded or welded. It is integrated with.

  As shown in FIGS. 2 and 3, the three-dimensional gather sheets 61, 61 are made of a non-woven fabric having flexibility such as an SMS non-woven fabric, and are paired so as to cover each lateral end of the top sheet 2 from the skin side. Is provided. Each three-dimensional gather sheet 61 is fixed to the top sheet 2 with an adhesive or the like, and can be raised on the skin side in the thickness direction with the base end portion 63 in the longitudinal direction that cannot stand up and the base end portion 63 as a fulcrum. The upright portions 65 are arranged in the horizontal direction. And the rubber thread 64 as the elastic member for three-dimensional gathers along the vertical direction is fixed to the tip part of the standing part 65 in the horizontal direction. Stands on the skin side in the thickness direction while forming a fold and functions as a three-dimensional gather 6. Further, fixing portions 62 and 62 for fixing the respective end portions are formed along the vertical direction at the respective vertical end portions of the standing portion 65.

  Note that the three-dimensional gather sheet 61 extends to the outer side in the lateral direction to substantially the same position as the outer edge of the outer sheet 5, and is integrated with the outer sheet 5 by adhesion or welding in the vicinity of this edge ( 2 and 3A to 3C). As a result, the three-dimensional gather sheet 61 and the exterior sheet 5 cooperate with each other in the first waistline portion 11, the second waistline portion 12, and the crotch portion 13, and the first side flaps 112, the second side flaps 122, and the A crotch side flap 132 is formed.

  Each crotch side flap 132 is a part that constitutes the leg opening 1HL together with each first side flap 112 and each second side flap 122, and covers the leg circumference of the low-weight child 9. And the rubber thread 8 along the vertical direction is fixed to each inseam side flap 132 as an elastic member of the leg gather portion by adhesion or the like in the stretched state. When the stretched state of the rubber thread 8 is relaxed, the crotch side flap 132 contracts in the vertical direction to form a plurality of ridges, and these ridges become leg gathers.

  The diaper 1 has a pair of cut lines 1c and 1c (first cut line and second cut line) and a cut line 2c cut as necessary (FIG. 2). Details will be described later.

  The fastening tapes 7 and 7 are provided at the second lateral ends 125 in the lateral direction of the pair of second side flaps 122 and 122, respectively (FIG. 2). Each fastening tape 7 uses a horizontally long belt-like sheet as a tape base, one end of the tape base in the horizontal direction is fixed to a part of the second side flap 122, and the other end is a second horizontal end 125. Protrudes outward in the lateral direction. A hook material 71 of a hook-and-loop fastener having a plurality of locking projections (not shown) is fixed to the skin side surface of the protruding portion. The fastening tape 7 is locked to the first waistline portion 11 by the hooking projections of the hook material 71 being hooked on the target region 114 provided on the non-skin side surface of the first waistline portion 11. As a result, a waistline opening 1HB and a pair of leghole openings 1HL, 1HL are formed, and the diaper 1 is attached to the low-weight infant 9 (FIGS. 4A and 4B).

<About wearing diapers 1>
The wearing of the diaper 1 in the present embodiment to the low-weight child 9 will be described.
When the diaper 1 is attached to the low-weight infant 9, the fastening tapes 7 are pulled by the pair of fastening tapes 7 and 7 to the both sides in the lateral direction, and each fastening tape 7 is moved to the first waist part 11 respectively. To the target region 114 (FIGS. 4A and 4B).

  Normally, when the low-weight child 9 is placed in a supine posture, the first waistline portion 11 of the diaper 1 covers the abdomen of the low-weight child 9 and the second waistline portion 12 covers the back (hereinafter, “normally” ”), A state as shown in FIG. 1A is obtained. The diaper 1 is pre-wrapped in the vertical direction with the narrowest part of the absorbent core 31 as a base point, and the narrowest part (first notch 33) is placed on the inseam of the low-weight child 9 when worn. Let Since the narrowest part (the first notch 33) is formed on the vertical end 123 side from the longitudinal center of the diaper 1, when the diaper 1 is attached to the low-weight child 9, the abdomen of the low-weight child 9 The back side is covered more widely. The waistline opening 1HB is in contact with the waistline of the low-weight child 9, the legline opening 1HL is in contact with the leg, and a part thereof is in contact with the shank.

  The low-weight child 9 is required to rest, and it is preferable not to change the posture as much as possible. Turning the low-weight child 9 in the prone posture every time the diaper is changed poses extra stress on the low-weight child 9 I will give it. In order to prevent this, the diaper is sometimes attached in the reverse direction. However, when the conventional diaper is attached in the reverse direction, the region for covering the back side widely covers the abdomen. The low-weight child 9 needs to carefully observe the condition, but if the abdomen is covered widely, the low-weight child 9 may not be able to observe the state of breathing, skin color, or the like.

  Therefore, as shown in FIG. 5, the first waistline portion 11 of the diaper 1 is used for the low-weight infant 9 by using a diaper 1 cut out by a cut line 2c and 1c described later for the low-weight infant 9 in the lying posture. The second waistline 12 covers the abdomen, and the hook material of the fastening tape 7 fixed to the second waistline 12 is locked to the first waistline 11 covering the back (hereinafter referred to as “front and back”). Even when wearing "reversely"), it is possible to observe the breathing state and skin color of the low-weight infant 9 without covering the abdomen of the low-weight infant 9 widely, and to reduce pressure on the groin Can do. FIG. 4B is a schematic perspective view of the diaper 1 in a mounted state after being cut along the cut lines 2c and 1c. When the diaper 1 cut off at the cut lines 2c and 1c is mounted reversely, the abdomen of the waist opening 1HB is exposed relatively widely, and the leg opening 1HL is wide open to compress the heel part. Reduce.

<About the cut line 2c>
Hereinafter, the cut line 2c will be described in more detail.
FIG. 6 is an enlarged view of a main part for explaining the cut line 2c. The cut line 2c is a line for cutting a part of the portion that becomes the waistline opening 1HB when mounted, and is formed by a plurality of elongated through holes. The length and interval of the through hole of the cut line 2c are appropriately set in consideration of cutting properties. For example, the length of the through hole can be set to 1 mm to 3 mm, and the interval between the through holes (the length of the portion without the through hole) can be set to 0.5 mm to 2 mm.

  The cut line 2c is provided on the vertical end 123 side of the absorber 3 and the fastening tape 7 in the vertical direction, and is a straight perforation along the horizontal direction. One end and the other end of the cut line 2 c are provided at the lateral ends of the second side flap 122.

  The second side flap 122 is provided with a curved portion connecting the vertical end 123 and the second horizontal end 125, and one end and the other end of the cut line 2 c are curves of the ends of the second side flap 122. Provided in the shape part. This one end or the other end is the starting point of cutting.

  The cut line 2c is a straight cut line that crosses the second side flap 122, the region between the two raised portions 65, and the second side flap 122 in this order from one lateral end to the other end.

  By cutting the cut line 2c, the abdomen side of the waistline opening 1HB can be opened more widely when the low-weight child 9 is mounted reversely. In addition, by providing the cut line 2c on the vertical end 123 side from the fastening tape 7, the function as the diaper 1 can be exhibited by locking with the fastening tape 7 even after the cut line 2c is cut. .

  FIG. 7 shows a center Y-Y that is a line along the horizontal direction passing through the vertical center of the fastening tape 7 and a center ZZ that is a line along the horizontal direction passing through the vertical center of the first horizontal end 115. It is a top view of the diaper 1 by which the skin side was folded inside so that it might match. As shown in FIG. 7, when the skin side is folded inward so that the center YY and the center ZZ are aligned, the product center XX is positioned on the vertical end 123 side from the folding line at this time. ing. In the folded state, the longitudinal end 113 is located between the longitudinal end 123 and the fastening tape 7 in the longitudinal direction. In this state, the cut line 2c is preferably provided between the vertical end 123 and the vertical end 113 in the vertical direction. Thereby, especially when attaching the diaper 1 to the low-weight infant 9 with a small body, it can be set as the diaper 1 suitable for a small body by cutting off with the cut line 2c.

  Further, by providing the cutting start point of the cut line 2c at the curved portion connecting the vertical end 123 and the second horizontal end 125, the cutting range can be made smaller than when the cutting start point is provided at the second horizontal end 125. Can do.

  The position of the cut line 2c in the vertical direction can be changed as appropriate according to the size of the body of the low-weight child 9 to be worn. For example, when the body of the low-weight child 9 is relatively small, the diaper 1 is wide and covers the abdomen of the low-weight child 9, so that the cut line 2c is formed on the vertical end 113 side in the vertical direction. The abdomen of the low-weight child 9 can be widely exposed. For example, the cut line 2c may be provided at the second lateral end 125. Thereby, since it becomes easy for an operator to support the diaper 1 at the time of cutting, it becomes easy to cut along the cutting line 2c.

  When the cutting start point of the cut line 2c is provided in the curved portion connecting the vertical end 123 and the second horizontal end 125, the two angles formed by the cut line 2c and the tangent line of the curved portion at one end of the cut line 2c Is an angle a and an angle b (a ≧ b), the angle b is preferably 45 degrees or more and 90 degrees or less. The same applies to the tangent of the curved portion at the other end of the cut line 2c. As the angle b is vertical (90 degrees), the operator tends to cut easily. For this reason, when the angle b is 45 degrees or more and 90 degrees or less, it becomes an angle at which a worker can easily apply a force when cutting, and can be easily cut off.

  A plurality of sheets exist in the thickness direction in the region where the cut line 2c is formed. Specifically, the three-dimensional gather sheet 61 and the exterior sheet 5 exist from the thickness direction skin side in the region of each second side flap 122 that does not have the leak-proof sheet 4, and each three-dimensional gather sheet 61 is provided. In the region having the leak-proof sheet 4 in the portion, the three-dimensional gather sheet 61, the top sheet 2 (inner side in the lateral direction), the leak-proof sheet 4 and the exterior sheet 5 are present from the skin side in the thickness direction. In the region between the sheets 61, the top sheet 2, the leak-proof sheet 4, and the exterior sheet 5 exist from the skin side in the thickness direction.

  The cut line 2c is formed by a perforation formed by a plurality of through holes penetrating the plurality of sheets 2, 4, 5, 61, so that the operator can cut the cut line 2c with a small force. it can.

  Of the cut line 2c, a portion e of the second side flap 122 provided in a region not including the leak-proof sheet 4 is a part e, and a portion provided in a region including the leak-proof sheet 4 of the three-dimensional gather sheet 61 is a part. f The part provided in the area between the two three-dimensional gather sheets 61 is defined as part g. Of the portion f, a portion where the top sheet 2 is not provided on the outer side in the horizontal direction is a portion f1, and a portion where the top sheet 2 is provided on the inner side in the horizontal direction is a portion f2. It is preferable that the through hole of the cut line 2c has a larger proportion of the length of the through hole per unit length than the part e and the part g with respect to the part f. That is, when the total length of the through holes in a certain length (for example, 1 cm) is compared, the total length of the through holes in the portion f is made larger so that the portion f is more than the portions e and g. The cut line is easy to cut. In particular, it is preferable to increase the ratio of the length of the through hole per unit length of the portion f2 where the number of sheets is the largest.

  Or you may make the ratio of the length of the through-hole per unit length in the part e larger than the part f and the part g. By making the total length of the through-holes of the part e at a certain length larger than the part f and the part g, the operator can cut the cutting start part with a smaller force.

  More preferably, the ratio of the length of the through-hole occupying per unit length of the part f2 is set to be the largest, the ratio of the part e and the part f1 is set to be approximately the same as that of the part f2, and the ratio of the part g is further set. It may be set smaller than the part e and the part f1. As a result, the portion f2 provided in the region with the largest number of sheets is easily cut, and subsequently the portion f1 provided in the region with the largest number of sheets and the portion e provided in the portion where the worker starts to cut are provided. By making it easier to cut from the part g, the operator can easily perform the work of cutting the cut line 2c.

  This ratio can be set, for example, by changing the length of the through hole. By changing the length of the through hole while maintaining the interval between the through holes constant, the ratio of the length of the through hole per unit length of the cut line 2c can be changed. Moreover, this ratio can be appropriately changed not only by the number of sheets (number of members) but also by the thickness and material of the members.

  In the present embodiment, the cut line 2c is formed by an elongated through hole, but the present invention is not limited to this. It is good also as a through-hole of predetermined shapes, such as a circular through-hole. Further, a predetermined number of sheets may be penetrated without penetrating all of the plurality of sheets, or a continuous cut may be formed as the cut line 1c.

  As described above, when the diaper 1 is normally attached to the low-weight child 9 without cutting along the cut line 2c, the abdomen can be exposed while covering the buttocks widely, while the lying posture is low. By attaching the diaper 1 cut along the cut line 2c to the weight child 9 in the reverse direction, the abdomen of the low weight child 9 can be exposed, and the skin of the low weight child 9 can be observed. . Thus, the diaper 1 of the present embodiment can provide a diaper suitable for both normal wearing and reverse wearing.

<About the cut line 1c>
The diaper 1 includes a cut line 1c (first cut line, second cut line) for cutting at least a part of the region on the vertical end 113 side in the vertical direction from the fastening tape 7 and outside in the horizontal direction from the absorber 3. One end and the other end of the first cut line 1c are provided at one end in the horizontal direction, and one end and the other end of the second cut line 1c are connected to one end in the horizontal direction. Is provided at the other end on the opposite side. Thereby, the pressure of the lower part of the low weight child 9 can be reduced, and the diaper 1 which can be worn reversely can be provided.

  At this time, it is preferable that the cut line 1 c is provided on the outer side in the lateral direction than the three-dimensional gather 6. Thereby, the fear that the excrement held inside the horizontal direction of solid gathers 6 may leak from a diaper can be reduced.

  Moreover, it is preferable that the cut line 1c is provided on the outer side in the lateral direction than the rubber thread 8 of the leg gathers. Thereby, a possibility that excrement leaks from the leg circumference can be reduced.

  Furthermore, it is preferable that one end of the cut line 1 c is provided at the second lateral end 125. Since the second horizontal end 125 is a portion where the operator can easily hold the diaper 1, the operator can easily cut the cut line 1 c.

  At this time, the cut line 1c is preferably provided from the second lateral end 125 to the inside of the fastening tape fixing portion 128 in the lateral direction. Usually, the fastening tape fixing | fixed part 128 is harder than the other part of the diaper 1. FIG. Therefore, if it cuts out from the 2nd horizontal end 125, the ridge part of the low weight child 9 will contact | abut to fastening tape fixing | fixed part 128 vicinity, and there exists a possibility that a hard part may press the ridge part. On the other hand, when the cut line 1c is provided from the fastening tape fixing portion 128 to the inner side in the lateral direction, the skirt portion comes into contact with the cushion region 129 inside the fastening tape fixing portion 128. The cushion region 129 is a portion of the side flap 10 made of a relatively soft material, and is a portion where the curved shape 1cB is formed, and has a function of softly contacting the ridge portion. Due to the function of the soft cushion region 129, it is possible to further prevent the heel portion from being strongly pressed. The cushion region 129 is formed symmetrically with respect to the horizontal center line C1 of the diaper 1.

  Each cut line 1c includes a curved first curved portion 1cA that protrudes outward in the vertical direction from one end of the cut line 1c and the vertical end 123 from the other end of the cut line 1c. And a second curved portion 1cB that connects the first curved portion 1cA and the linear portion 1cL while being located laterally inward of the first curved portion 1cA. . At this time, the second curved portion 1cB preferably has a larger curvature than the first curved portion 1cA. Thereby, even if the diaper 1 is worn reversely, the shape can be made along the heel portion of the low-weight child 9, and the pressure on the heel portion of the low-weight child 9 can be reduced.

  It is preferable that the other end of this cut line 1c is located in the longitudinal end 123 side rather than the longitudinal direction center XX of the diaper 1, respectively. Thereby, even if the diaper 1 is worn reversely, the risk of pressure on the butt portion of the low-weight child 9 can be reduced.

  Furthermore, it is preferable that the other end of the tear line 1c is provided closer to the vertical end 123 than the narrowest portion of the absorber 3. When the diaper 1 is attached to the low weight child 9, the narrowest portion is in a position corresponding to the crotch part of the low weight child 9. By cutting off the vertical end 123 side from the position, it is possible to reduce the risk of pressure on the heel portion of the low-weight infant 9 without forming the cut line carelessly long.

  Moreover, it is preferable that the angle which the tangent in the edge part of the horizontal direction of the 1st curvilinear part 1cA of the cut line 1c and the linear part 1cL makes is 82.5 degrees or more and 102.5 degrees or less. Thereby, the diaper suitable for the shape of the lower part of the low weight child 9 can be provided.

  Similarly to the cut line 2c, the cut line 1c is preferably formed by a plurality of through holes penetrating in the thickness direction. This is because the cut line 1c can be cut with a small force.

  Furthermore, when comparing the ratio of the length of the through hole per unit length of the cut line 1c, it is more preferable that the ratio of the first curved portion 1cA is smaller than the ratio of the linear portion 1cL. . When starting to cut from the first curved portion 1cA, it is easy to apply a force at the beginning, and it is easy to separate, so there is a risk of unexpectedly cutting beyond the cut line. On the other hand, the straight portion 1cL is difficult to apply a force and the separation is difficult. It can be difficult. Therefore, the ratio of the through holes in the first curved portion 1cA where the force is easily applied is reduced to prevent cutting other than the cut line by mistake, and the ratio of the through holes in the straight upper portion 1cL where the force is difficult to be applied is relatively large. By doing so, the linear part 1cL can be easily cut off.

=== Other Embodiments ===
As mentioned above, although embodiment of this invention was described, said embodiment is for making an understanding of this invention easy, and is not for limiting and interpreting this invention. Further, the present invention can be changed or improved without departing from the gist thereof, and needless to say, the present invention includes equivalents thereof. For example, the following modifications are possible.

  In the above-described embodiment, the cut line 2c is formed in a straight line shape, but is not limited thereto. A curved shape that is convex in any one of the vertical directions or a zigzag shape may be used. For example, if it is formed in a curved shape that is convex toward the vertical end 113 side, it can be appropriately changed, such as a shape that follows the roundness of the abdomen of the low-weight child 9. Further, a plurality of cut lines 2c may be provided.

  FIG. 8 is an enlarged view of a main part for explaining a cut line 2c according to another embodiment. As shown in FIG. 8, a notch 2k is formed as a mark indicating the position of the cut line 2c at the lateral end of the second side flap 122 where one end of the cut line 2c is located. The notch 2k is formed in a substantially V shape on the inner side in the horizontal direction.

  The notch portion 2k makes it easier for the operator to visually recognize the position of the cut line 2c, and also recognizes the position of the cut line 2c by touching the notch 2k with a hand even in a dimly lit working environment. it can. Further, when starting to cut the cut line 2c, it is possible to cut with a relatively small force.

  The mark indicating the position of the cut line 2c is not limited to the substantially V-shaped notch 2k. For example, a desired shape such as a semicircular cutout may be formed, and a knob that protrudes from the second side flap 122 may be formed. Further, one end of the cut line 2c may be colored as a mark. Similarly, the cut line 1c may be provided with a mark such as a notch 1k.

  Furthermore, in the above-described embodiment, the cut line 2c is formed by the perforation by the through hole penetrating the plurality of sheets 2, 4, 5, 61, but is not limited thereto. For example, the cut line 2c may be formed on the exterior sheet 5 (corresponding to the first sheet) and not formed on the top sheet 2, the leak-proof sheet 4, and the three-dimensional gather sheet 61 (corresponding to the second sheet). .

  Thus, the diaper 1 was pulled in the vertical direction by forming the cut line 2c on the exterior sheet 5 and not forming the cut line 2c on the top sheet 2, the leak-proof sheet 4, and the three-dimensional gather sheet 61. In this case, a tensile force that can act on the cut line 2c can be effectively received on the three-dimensional gather sheet 61 side where the cut line 2c is not formed. As a result, it is possible to prevent a situation where the cut line 2c is unintentionally cut off.
