Description

  The present invention relates to an absorbent article for a wearing assistant to wear on an adult wearer.

  Conventionally, an absorbent article for a wearing assistant to wear on a wearer is known. For example, Patent Documents 1 and 2 disclose a tape-type disposable diaper as an absorbent article. The tape-type disposable diaper has a crotch region applied to the wearer's inseam, a front waist region applied to the wearer's abdomen, and a back waist region applied to the wearer's back side. Fastening members that can be fastened to the other of the front waistline region and the rear waistline region are provided on both outer sides in the width direction of either the front waistline region or the rear waistline region.

  When the wearing assistant wears such a tape-type disposable diaper on the wearer, for example, after lifting the waist around the wearer and laying a rear waist area below the waist, the front waist area Thus, the abdomen of the wearing assistant is covered, and the fastening member provided in the rear waistline region is fastened to the front waistline region.

  However, for example, when a caregiver as a wearing assistant wears an absorbent article on an adult wearer, the caregiver lifts the waist circumference of the wearer and lays a rear waist area below the waist circumference. It is difficult. Therefore, for example, the disposable diaper 100 can be attached to an adult wearer who is lying on his / her back by the method shown in FIG. The wearing assistant first changes the position of the wearer. Specifically, the state is changed from the state of lying on the back (FIG. 9A) to the state of lying on the side (FIG. 9B). The wearing assistant lays the disposable diaper 100 on the back side of the wearer so that the center 100CL in the width direction of the disposable diaper matches the center of the body in a state where the wearer is laid sideways. At this time, the wearing assistant gathers the first region 101 on the side where the body is lower with respect to the center 100CL in the width direction of the disposable diaper, brings the first region 101 near the lower side of the body, and the first region 101 The second region 102 on the opposite side is spread in a spread state (FIG. 9B). Next, the wearing assistant changes the position of the wearer so that the wearer's body rides on the second region 102 (FIG. 9C). Next, the wearing assistant changes the position of the wearer from the supine state to the opposite sideward state (FIG. 9D), and the first region 101 is placed outward in the width direction from below the wearer's body. Pull out (FIG. 9E). Next, the wearing assistant changes the position of the wearer to the back again, covers the abdomen of the wearing assistant with the front waistline region, and fastens the fastening member 107 provided in the rear waistline region to the front waistline region ( FIG. 9 (f)).

  Patent Document 3 discloses a pants-type disposable diaper as an absorbent article. The pants-type disposable diaper has a crotch region applied to the wearer's inseam, a front waist region applied to the wearer's abdomen, and a rear waist region applied to the wearer's back side. The region and the rear waistline region are joined to each other at both outer edges.

  When such a pants-type disposable diaper is worn by the wearer on the wearer, for example, for a standing wearer, both the legs of the wearer are passed through the diaper, and the front waistline region and the rear Pull the waist area up to the wearer's waist. Moreover, with respect to the wearer in the sleeping state, both the legs of the wearer are passed through the diaper, and the front waistline region and the back waistline region are pulled up to the front side (leg side) of the waistline of the wearer in the sleeping state. Then, the wearing assistant lifts the buttocks of the wearer with both the legs of the wearer, realizes a state where the body floats with respect to the bedding, and pulls up the diaper around the wearer's waist.

At least the following matters will become apparent from the description of the present specification and the accompanying drawings.
The front-rear direction and the width direction orthogonal to each other;
Inseam area,
A first waistline region located outside the crotch region in the front-rear direction and having a fastening member;
A second waistline region located on the outer side in the front-rear direction than the crotch region, to which the fastening member can be fastened;
An absorbent body extending from the crotch region to at least one of the first waistline region and the second waistline region;
An absorbent article comprising an elastic member that expands and contracts in the width direction,
The outer edge on one side of the first waistline region in the width direction and the outer edge on one side of the second waistline region in the width direction are joined by a side joint portion,
The fastening member is provided on the outer edge on the other side of the first waistline region in the width direction,
The elastic member has an inclined part (inclined part 61D) that is disposed across the outer edge of the absorber and extends from the inner side in the width direction toward the outer side in the front-rear direction.
The inclined part is an absorbent article provided on at least the other side of the first waistline region and not provided in the second waistline region.

  According to such an absorbent article, the wearer in a sleeping state with the other side of the absorbent body covering the wearer's body in a state in which the wearer's one leg is passed through one side of the absorbent article In contrast, an absorbent article can be attached. Wearing an absorbent article to a wearer in a state where the wearing assistant is lying on his / her back by changing the position of the wearer twice, that is, a change in the position from the supine to the side and a change in the position from the side to the supine Can do. Therefore, it is possible to reduce the number of times the posture is changed and to reduce the burden on the wearing assistant and the wearer by repeatedly changing the posture.

  Moreover, the inclination part which straddles the outer edge of an absorber, and a fastening member are provided in the other side of the 1st waist area of an absorbent article. When the wearer is lying on his / her back, the wearing assistant pulls the fastening member to the outside on the other side of the absorbent article, so that the inclined portion is also pulled to the outside in the width direction. The width of the absorber can be widened by the inclined portion, and the inclined portion can be applied so as to be along the heel portion or the base of the heel portion. Moreover, when the wearing assistant pulls the other side of the absorbent article to the outside in the width direction, the edge of the absorbent body can be pulled up to the outside in the front-rear direction by the inclined portion. The absorber in the crotch region is pulled up to the wearer's crotch side and is in close contact with the body. On the other hand, the inclined portion is not provided in the second waistline region. Therefore, it is difficult for contraction force to be generated at the outer edge of the absorbent body in the second waistline region so as to be directed inward in the width direction and toward the crotch region. If the inclined portion is arranged in the second waistline region, the second waistline region extends and contracts in an oblique direction, and when the fastening member is fastened, the wearing assistant extends the hand so that the inclined portion is extended. It may need to be accompanied and may increase the physical burden on the wearer. Since the inclined portion is not provided in the second waistline region, it is not necessary for the wearing assistant to extend in the width direction when the fastening member is fastened, and the physical load can be minimized. The absorbent article can be mounted in a state where the entire absorbent body in the second waistline region is placed along the wearer's body without the wearing assistant performing the work of pulling the second waistline region in the width direction.

Such an absorbent article,
It is desirable that the inclined portion is disposed across the outer edge of the absorber on the other side of the first waistline region and the one side of the first waistline region.

  According to such an absorbent article, the first elastic member is disposed so as to straddle the outer edge of the absorbent body on the one side of the first waistline region and the outer edge of the absorbent body on the other side. The absorber can be pulled up from the crotch side to the first waistline side on both the one side and the other side. Moreover, the width direction whole area of an absorber is extended by the 1st elastic member, wrinkles and twist are reduced in the width direction whole area of an absorber, and it is easy to maintain a planar state. The planar absorbent body can be brought into close contact with the wearer's crotch. Moreover, the inclined part can be along the base of both collar parts or both collar parts by extending the absorber of one side also in the diagonal direction.

Such an absorbent article,
The elastic member in the first waistline region has a pair of inclined portions and a central portion that connects between the pair of inclined portions and expands and contracts along the width direction,
It is desirable that an extension magnification of the inclined portion in the extended state where the absorbent article is extended is higher than an extension magnification of the central portion in the extended state.

  According to such an absorbent article, since the expansion ratio of the central portion is relatively low, it is possible to suppress the width of the absorbent body from being shortened by the contraction of the first elastic member. Moreover, since the expansion | extension magnification of an inclination part is comparatively high, the raising effect of the absorber by shrinkage | contraction of a 1st elastic member can be exhibited more. That is, by making the expansion ratios of the central portion and the inclined portion different, it is possible to obtain the effect of lifting the absorber while suppressing the width of the absorber from becoming narrow. In addition, both the outer edge of the absorber on one side and the outer edge of the absorber on the other side can be extended in an oblique direction to widen the width of the absorber, and an inclined portion is provided at the base of both ribs or both ribs. Can be along.

  Further, since the inclined portion and the central portion are continuous, the left and right inclined portions are interlocked, and the entire width direction of the absorber can be pulled by the first elastic member. Therefore, when the wearing assistant pulls the other side of the first waistline portion, not only the outer edge on the other side of the absorber but also the outer edge on the one side of the absorber is easily pulled, and the entire width direction of the absorber It becomes easy to adjust the position. It becomes easy to make the entire width direction of the absorbent body in the first waist area flat, and the absorbent body is disposed along the body, and the leg opening around the width direction outside the absorbent body is legged to the wearer. It can be fitted without gaps around.

Such an absorbent article,
The second waistline region is provided with a target portion to which the fastening member is fastened, and a front-rear non-stretchable region that does not stretch in the front-rear direction,
The front / rear non-stretchable region preferably overlaps the entire target portion.

  According to such an absorbent article, the target portion overlaps the front / rear non-stretchable region, and can maintain a state in which it does not contract in the front / rear direction. Therefore, the fastening member is easily attached to the target portion. Moreover, the target part may be in a state contracted in the width direction by an elastic member arranged in the front waistline region. When the fastening member is fastened to the target portion, a force along the wearer's waist is applied to the target portion and the fastening member. By this force, wrinkles and kinks due to shrinkage in the width direction in the target portion are eliminated. Further, only the force along the width direction is applied to the target portion when the fixing member is fixed, and the force along the front-rear direction and the force inclined with respect to the width direction are hardly applied. Therefore, unintentional wrinkles and twists are prevented from occurring in the target portion when the fastening member is fastened, and the fastening member is fastened to the target portion in a flat state, and the fastened state is easily maintained. In addition, since the target part and the fastening member are subjected to a force along the waist of the wearer, and it is difficult to apply a force along the front-rear direction or a force inclined with respect to the width direction, the fastening member is attached to the target part. After that, due to the elastic stress in the first waistline region, each other is a force along the width direction and is pulled in the opposite direction. Therefore, the tip of the fastening member can easily enter the target portion, and the fastening state can be easily maintained.

Such an absorbent article,
A target portion to which the fastening member is fastened is provided in the second waistline region,
A first leg opening provided on the one side of the absorbent article and a second leg formed on the other side of the absorbent article in a state where the fastening member is fastened to the target part An opening, and
In the extended state in which the absorbent article is extended, it is desirable that the length of the first leg opening is shorter than the length of the second leg opening.

  As a usage mode of the absorbent article, not only a mode in which the entire absorbent article is replaced after use, but an absorbent pad is disposed inside the absorbent article and only the absorbent pad is replaced after use. Thus, when only the absorbent pad is replaced, an opening for inserting and removing the absorbent pad is formed on the other side by removing the fastening member, so that one leg of the wearer is inserted into the opening around the first leg In this state, the absorbent pad can be replaced.

  Since the length of the first leg-hole opening is shorter than the length of the second leg-hole opening, the first leg-hole opening easily adheres to the wearer's leg. When the wearer moves at the time of replacement of the absorbent pad or the wearing assistant moves the absorbent article, the first leg opening is prevented from moving unintentionally, and the absorbent article is attached or absorbed. The pad replacement work can be carried out smoothly. Moreover, since the opening part around the second leg is relatively wide, an opening for taking in and out the absorbent pad can be formed widely, and the replacement work of the absorbent pad can be proceeded smoothly.

Such an absorbent article,
The first waistline region is provided with a first elastic region that expands and contracts along the width direction outside the absorber in the width direction,
The distance in the width direction between the outer edge on the one side of the first elastic region and the center of the crotch region is the width direction between the outer edge on the other side of the first elastic region and the center of the crotch region. It is desirable to be shorter than the distance at.

  When the wearer's leg is passed through the opening around the first leg and the crotch region is aligned with the center of the wearer's body, the other side of the first waist region is pulled to obtain the first elasticity. The area grows. At this time, the crotch region may move to the other side as the first rear elastic region extends. According to such an absorbent article, the distance in the width direction between the outer edge on one side of the first elastic region and the center of the crotch region is set in advance in anticipation of the movement, and the outer edge and crotch region on the other side of the first elastic region. By making it shorter than the distance in the width direction with the center of the crotch, it is possible to suppress the crotch region from moving too far to the other side, and to prevent the crotch region from shifting from the center of the wearer's body.

Such an absorbent article,
The first waistline region is provided with a first elastic region that expands and contracts in the width direction outside the absorber in the width direction,
The second waistline region is provided with a second elastic region that expands and contracts in the width direction outside the absorber in the width direction,
The expansion / contraction rate in the width direction of the first elastic region is desirably lower than the expansion / contraction rate in the width direction of the second elastic region.

  According to such an absorbent article, since the expansion / contraction rate of the first elastic region is relatively low, the first waistline region does not contract too much when the absorbent article is mounted, and the width of the first waistline region can be secured. Therefore, it is easy to arrange the first waistline region where the fastening member is provided under the wearer's body when the absorbent article is mounted. In addition, even when the first elastic region has a relatively low expansion / contraction rate and the first waistline region is not in close contact with the wearer's body in a natural state, the attachment assistant is required to attach the fastening member to the target portion. However, by pulling the first waistline region to the other side, the first waistline region can be brought into close contact with the wearer's body. On the other hand, since the second waistline region has a relatively high expansion / contraction rate, it is easily placed in close contact with the wearer's body.

Such an absorbent article,
The first elastic region and the second elastic region are preferably separated from an absorber arrangement region that overlaps the absorber.

  According to such an absorbent article, the absorbent body can be prevented from shrinking due to the shrinkage of the first elastic region and the second elastic region, and can be worn on the wearer while ensuring the width of the absorbent body.

Next, the first elastic member 61 is removed from the exterior sheet and left in an atmosphere of 20 ° C. ± 2 ° C. and relative humidity 60% ± 5% for 24 hours. The length of the rear inclined portion 61D and the length of the central portion 61C in the state of being left are measured and set as the length of the natural state. Based on the measured “length in the state of being bonded to the exterior sheet” and “length in the natural state”, the expansion ratio is calculated.

  The third elastic member 62 is located behind the first elastic member 61 in the front-rear direction L. The third elastic member 62 is disposed in parallel with the width direction W and expands and contracts along the width direction W. The third elastic member 62 is not disposed in a region overlapping with the absorber 13, but is disposed outside the absorber 13 in the width direction W and behind the absorber 13 in the front-rear direction L. The 2nd elastic member 63 is a 2nd elastic member in this invention, and is arrange | positioned at the front waistline part 22 as a 2nd waistline area. The second elastic member 63 is disposed in parallel with the width direction W and expands and contracts along the width direction W. The second elastic member 63 is not disposed in a region overlapping with the absorber 13, but is disposed on the outer side in the width direction with respect to the absorber 13 and on the front side in the front-rear direction with respect to the absorber 13.

  The inclined portion 61D of the first elastic member 61 is provided in a state of extending in the width direction W and the front-rear direction L. Therefore, the region where the inclined portion 61D is disposed expands and contracts in the width direction W and the front-rear direction L. Further, the central portion 61C of the first elastic member 61, the side portion 61L of the first elastic member 61, the third elastic member 62, and the second elastic member 63 are provided in a state where only the width direction W is extended. Therefore, the region where the central portion 61C of the first elastic member 61, the side portion 61L of the first elastic member 61, the third elastic member 62, and the second elastic member 63 are expanded and contracted in the width direction W, and the front-rear direction L It does not expand and contract, and it constitutes a front / rear non-stretchable region. Moreover, the area | region where the 1st elastic member 61, the 3rd elastic member 62, and the 2nd elastic member 63 is not arrange | positioned in the exterior body 20 does not expand-contract in the width direction W and the front-back direction L, but comprises a back non-expandable area | region. . That is, the front-rear non-stretchable region is a region where the central portion 61C of the first elastic member 61 and the side portion 61L of the first elastic member 61 are not disposed in the exterior body 20. The front / rear non-stretchable region is disposed at least in a region overlapping the absorber 13 in the front waistline region S2 and the rear waistline region S3. The front / rear non-stretchable region is a region that is not contracted in the front / rear direction by the elastic member provided in the exterior body, and is a concept that includes a region where the leakproof elastic member 16 provided in the absorbent main body 10 is disposed.

  As shown in FIG. 4, the rear waistline portion 23 is provided with a rear elastic region R62 that expands and contracts in the width direction outside the absorber 13 in the width direction. Further, the front waistline portion 22 is provided with a front elastic region R63 that expands and contracts in the width direction outside the absorber 13 in the width direction. The rear elastic region R62 and the front elastic region R63 expand and contract in the width direction W and do not expand and contract in the front-rear direction L. Therefore, it is easy to secure an area covering the waist circumference (abdomen and buttocks) of the wearer, the body can be properly covered, and a sense of security can be given to the wearer and the wearer. Further, when the front waistline portion and the rear waistline portion are pulled in the width direction at the time of mounting, the rear elastic region R62 and the front elastic region R63 extend in the width direction W, and wrinkles are eliminated. Therefore, the operation | movement which extends a wrinkle other than mounting | wearing operation | movement so that the wrinkles of back elastic area | region R62 and front elastic area | region R63 is not formed becomes unnecessary, and can improve work efficiency.

  The rear elastic region R62 and the front elastic region R63 are separated from the absorber arrangement region that overlaps the absorber 13. That is, the rear elastic region R62 and the front elastic region R63 do not overlap the absorber 13 in the thickness direction T. The absorber 13 can be prevented from contracting due to the contraction of the rear elastic region R62 and the front elastic region R63, and can be attached to the wearer while the width of the absorber 13 is secured.

  The expansion / contraction rate in the width direction W of the rear elastic region R62 is lower than the expansion / contraction rate in the width direction of the front elastic region R63. Since the expansion / contraction rate of the rear elastic region R62 is relatively low, the rear waistline region S3 does not contract too much when the absorbent article 1 is mounted, and the width of the rear waistline region S3 can be secured. Therefore, the rear waistline region S3 can be arranged at the time of mounting in a state where the width of the rear waistline region S3 is secured. When the position of the wearer is changed at the time of wearing, the rear waistline region S3 can be prevented from entering between the body and the bedding. Further, since the front elastic region R63 has a relatively high expansion / contraction rate, the front waistline region S2 is in close contact with the wearer's body when the front elastic region R63 is contracted. On the other hand, in the rear waistline region S3, the expansion / contraction ratio of the rear elastic region R62 is relatively low, and it is difficult for the rear waist region S3 to be in close contact with the wearer's body when the rear elastic region R62 contracts. However, the wearing assistant pulls the rear waistline region S3 in the width direction when the fastening member 27 is fastened to the target portion 28 at the time of wearing. At this time, since the rear elastic region R62 extends, the rear waistline region S3 can be disposed so as to cover and closely adhere to the wearer's body.

The expansion / contraction rate means the degree of expansion / contraction in the width direction of the front elastic region and the rear elastic region, and can be defined as follows.
Stretch rate of the front elastic region = (length of the stretched state of the front elastic region in the product) / (length of the natural state of the front elastic region in the product)
Stretch rate of the rear elastic region = (length of the extended state of the rear elastic region in the product) / (length of the natural state of the rear elastic region in the product)

  The expansion / contraction rate can be measured as follows. The side joint portion formed on one side of the absorbent article is cut to bring the absorbent article into a developed state. The unfolded absorbent article is left in an atmosphere of 20 ° C. ± 2 ° C. and relative humidity 60% ± 5% for 24 hours. Using the left absorbent article as a natural absorbent article, the length in the width direction of the front elastic region in the natural state and the length in the width direction of the rear elastic region in the natural state are measured. Next, the absorbent article is stretched until no wrinkles of the absorbent article are formed, and the length in the width direction of the front elastic region in the stretched state and the length in the width direction of the rear elastic region in the stretched state are measured. Based on the measured “length of the natural state” and “length of the extended state”, the expansion / contraction rate is calculated.

  The exterior body 20 is asymmetric with respect to the width center line 13WL. Specifically, the length in the width direction W on the one side W1 of the exterior body 20 is shorter than the length in the width direction W on the other side W2 of the exterior body 20. At least one of the front waistline portion 22 and the rear waistline portion 23 is asymmetric with respect to the width center line 13WL. As shown in FIG. 4, the length L11 in the width direction W on the one side W1 of the rear waistline portion 23 is shorter than the length L12 in the width direction W on the other side W2 of the rear waistline portion 23. The length L11 in the width direction on one side W1 of the rear waistline portion 23 is a distance in the width direction W between the outer edge 23E1 on one side W1 of the rear waistline portion 23 and the width center line 13WL. The length L12 in the width direction of the other side W2 of the rear waistline portion 23 is a distance in the width direction W between the outer edge 23E2 of the other side W2 of the rear waistline portion 23 and the width center line 13WL. Further, the rear elastic region R62 is asymmetric with respect to the width center line 13WL. The distance L13 between the outer edge R62E1 on one side W1 of the rear elastic region R62 and the center of the crotch region S1 is shorter than the distance L14 between the outer edge R62E2 on the other side W2 of the rear elastic region R62 and the center of the crotch region S1. The center of the crotch region S1 coincides with the width center line 13WL. Further, the outer edge R62E1 on one side W1 of the rear elastic region R62 coincides with the outer edge 23E1 on one side W1 of the rear waistline portion 23. The outer edge R62E2 on the other side W2 of the rear elastic region R62 coincides with the outer edge 23E2 on the other side W2 of the rear waistline portion 23.

  In the extended state of the absorbent article, the length of the first leg opening 32a is shorter than the length of the second leg opening 32b. In the expanded state shown in FIG. 4, the length of the first leg opening 32 a in the extended state is such that the rear end edge P <b> 1 at the outer edge 22 </ b> E <b> 1 on one side W <b> 1 of the front waistline 22 and the one side W1 of the rear waistline 23. This is the length of the front edge P4 of the outer edge 23E1. More specifically, the length of the first leg opening 32 a is the length of the exterior from the rear edge P 1 on the outer edge of the one side W 1 of the front waist 22 to the intersection P 2 of the front waist 22 and the absorbent main body 10. The length of the outer edge of the body 20, the length of the outer edge of the absorbent main body 10 from the intersection P2 of the front waistline portion 22 and the absorbent main body 10 to the intersection P3 of the rear waistline portion 23 and the absorbent main body 10, and the rear waistline The length of the outer edge of the exterior body 20 from the intersection part P3 of the part 23 and the absorbent main body 10 to the front end edge P4 at the outer edge of the one side W1 of the rear waistline part 23 is the combined length. Further, the length of the second leg-hole opening 32b is such that the rear edge P5 at the outer edge 22E2 on the other side W2 of the front waistline 22 and the front edge P8 at the outer edge 23E2 on the other side W2 of the rear waistline 23 The length of More specifically, the length of the second leg-hole opening 32b is the length of the exterior from the rear end edge P5 on the outer edge of the other side W2 of the front waistline 22 to the intersection P6 of the front waistline 22 and the absorbent main body 10. The length of the outer edge of the body 20, the length of the outer edge of the absorbent main body 10 from the intersection P6 of the front waistline portion 22 and the absorbent main body 10 to the intersection P7 of the rear waistline portion 23 and the absorbent main body 10, and the rear waistline The length of the outer edge of the exterior body 20 from the intersection part P7 of the part 23 and the absorbent main body 10 to the front end edge P8 at the outer edge 23E2 on the other side W2 of the rear waistline part 23 is the combined length.

  A fastening member 27 that extends outward in the width direction from the exterior sheet is provided on the rear waistline portion 23 of the exterior body 20. The fixing member 27 is configured to be fixed to the target portion 28 of the front waistline portion 22. The fastening member 27 has a substantially rectangular shape in plan view, and includes a base sheet 27 a and a locking portion 27 b that can be engaged with the target portion 28. An example of the locking portion 27b is a hook-and-loop fastener having a plurality of locking protrusions (hooks). The target portion 28 is provided on the non-skin facing surface side T <b> 2 of the front waistline portion 22 of the exterior body 20. The target portion 28 has a substantially rectangular shape in plan view. Examples of the target portion 28 include a hook-and-loop fastener and a nonwoven fabric having a loop that engages with a hook.

  At least a part of the target portion 28 overlaps the front / rear non-stretchable region in the thickness direction T. The front / rear non-stretchable region of the present embodiment overlaps the entire target portion 28. The target portion 28 overlaps with the front / rear non-stretchable region and can maintain a state in which it does not contract in the front / rear direction. Therefore, the fastening member 27 is easily attached to the target portion 28.

  Moreover, the skin side sheet | seat 25 and the non-skin side sheet | seat 26 which comprise an exterior sheet | seat have the folding | returning part 25a, 26a folded back inside the front-back direction in the front-end edge and rear-end edge of the absorbent article 1. FIG. The folded portion is disposed on the skin facing surface side of the absorbent main body 10 and is joined to the leakage preventing portion 15. Of the region where the folded portions 25a, 26a and the absorbent main body 10 overlap, the side portions in the width direction are joined together, and the center portions in the width direction are not joined together. Therefore, the folded portions 25a, 26a and the absorbent main body 10 can be separated from each other at the center in the width direction of the region where the folded portions 25a, 26a and the absorbent main body 10 overlap, and an absorption pad described later can be held. it can.

(2) Mounting Mode of Absorbent Article Next, an example of a mounting mode when the mounting assistant (wearing person) wears the absorbent article 1 configured as described above on a wearer lying on his back. explain. FIGS. 6 and 7 are diagrams for explaining the wearing mode, and FIGS. 6A to 6E show a state in which the wearer is viewed from above, and FIG. It is sectional drawing along the XX line shown to 6 (b). FIG. 7 is a schematic rear view of the wearer as viewed from the back side.

  The wearing assistant inserts one leg of the wearer lying on his back into the first leg opening 32a (FIG. 6A). At this time, since the first leg opening 32a is narrower than the second leg opening 32b, the wearing assistant pushes the disposable diaper up to the vicinity of the wearer's crotch, so that the wearer's buttocks The disposable diaper can be continuously arranged at a close position, and can be more easily worn.

  Next, the wearing assistant turns the wearer sideways so that the leg on the side inserted into the first leg opening 32a faces upward, and pulls up the absorbent article 1 to a position around the waist of the wearer (FIG. 6). (B)). At this time, since the first elastic member 61 is disposed so as to straddle the outer edge 13E of the absorber 13 on one side of the rear waistline portion 23, the absorbent article 1 is pulled up to the position around the waist of the wearer. The absorber 13 on one side W1 is pulled up from the crotch region S1 side to the rear waistline region S3 side, and the absorber 13 on one side approaches the wearer's crotch. At this time, since the expansion magnification of the inclined portion 61D of the first elastic member 61 is higher than the expansion magnification of the central portion 61C of the first elastic member 61, the inclined portion 61D of the first elastic member 61 causes the outer side of the absorber 13 to move. It is easy to exert the effect of pulling up the edge 13E backward. Moreover, since the expansion | extension magnification of the center part 61C of the 1st elastic member 61 is comparatively low, and the center of the width direction of the absorber of a 1st waist area is hard to shrink, it is easy to make a disposable diaper follow a collar part. Further, since the first waistline region does not shrink too much in the width direction, the second leg opening 32b positioned on the fastening member side does not enter the inside in the width direction, and the fastening member 27 is prepared for the next operation. It is possible to place the other side of the second waistline region, which is a region where the rubber is fastened, as far as possible outside in the width direction.

  In the state shown in FIG. 6B, the lower side of the wearer's waist (the right side of the waist in the example shown in FIG. 6) is in contact with the bedding. The wearing assistant places the outer edge 23E2 on the other side W2 of the rear waistline portion 23 in the vicinity of the surface where the wearer's waistline and the bedding contact (FIG. 6 (f)). More specifically, the outer edge 23E2 of the other side W2 of the rear waistline portion 23 is disposed on the bedding side with respect to the swelling of the body's buttocks. By arranging the absorbent article 1 in this way, the front waistline portion 22 of the absorbent article 1 is attached to the wearer's stomach side, and the rear waistline portion 23 of the absorbent article 1 is attached to the wearer's back side. Arranged.

  Next, the wearing assistant turns the wearer on his / her back (FIG. 6C). When the position of the wearer changes to the back, the wearer's buttocks are arranged on the rear waistline portion 23 arranged along the back side in a sideways state. The outer edge 23E2 on the other side E2 of the rear waistline portion 23 extends outward in the width direction W from the body. At this time, since the expansion / contraction ratio of the rear elastic region R62 is relatively low, the rear waistline portion 23 does not contract too much, and the width of the rear waistline portion 23 can be secured. Therefore, the back waistline part 23 is easy to arrange | position between a wearer and bedding. When the outer edge 23E2 on the other side W2 of the rear waistline portion 23 is under the body, the wearing assistant moves the outer edge 23E2 on the other side W2 of the rear waistline portion 23 from between the body and the bedding. Pull it out in the width direction.

  The width center line 13WL of the absorbent body 13 is positioned on the leg side that has passed through the first leg opening 32a rather than the center of the body in such a state that the position of the wearer has changed to the back (see FIG. 7 (a)). )). This is because the absorbent article 1 is pulled toward the opening portion around the first leg where the leg is inserted. Further, the crotch region S1 is not in close contact with the wearer's crotch. When the absorbent article 1 is pulled up with one leg passing through the first leg opening 32a, the wearer is turned sideways and the entire absorbent article 1 cannot be pulled up to the waist of the wearer. It is.

  Next, the wearing assistant pulls the other side W2 of the rear waistline portion 23 outward in the width direction (FIG. 6D). When the other side W2 of the rear waistline portion 23 is pulled outward in the width direction W, the absorber 13 is also pulled to the other side, and the absorber 13 is positioned so that the width center line 13WL of the absorber 13 is aligned with the center of the body. Be placed. At this time, since the inclined portion 61D of the first elastic member 61 is disposed so as to straddle the outer edge 13E of the absorber 13 on the other side W2 of the rear waistline portion 23, the absorber 13 is disposed on the other side W2 and rearward. Be raised. By providing the inclined portion 61D of the first elastic member 61, the absorbent body 13 disposed in the crotch can be pulled rearward, and the wrinkles and steps of the absorbent body 13 disposed in the crotch are reduced. The absorber 13 arranged in the crotch can be brought into close contact with the body. At this time, since the expansion magnification of the inclined portion 61D of the first elastic member 61 is higher than the expansion magnification of the central portion 61C of the first elastic member 61, the inclined portion 61D of the first elastic member 61 causes the outer side of the absorber 13 to move. It is easy to exert the effect of pulling up the edge 13E backward. In addition, since the inclined portion 61D is provided on the outer edge and the outer edge on the other side on one side of the absorber, the width of the absorber 13 can be increased by the inclined portion 61D, and the inclined portion 61D can be Can be applied along the root of Further, since the inclined portion 61D and the central portion 61C of the first elastic member 61 are continuous, the left and right inclined portions 61D are interlocked, and the first elastic member 61 may pull the entire width direction of the absorber 13. it can. Therefore, when the wearer pulls the other side of the rear waistline portion 23, not only the outer edge 13E on the other side of the absorbent body 13 but also the outer edge 13E on one side of the absorbent body 13 can be easily pulled. It becomes easy to adjust the position of 13 width direction whole areas. Therefore, the center in the width direction of the absorbent article substantially coincides with the center in the width direction of the body, and the crotch part 21 of the absorbent article is in close contact with the wearer's crotch (FIG. 7B). As described above, when the absorbent article is pulled up around the wearer's waist with the wearer sideways so that the leg on the side inserted into the first leg opening 32a is up, one side of the absorbent body The side is raised to the rear side. Therefore, by pulling the other side W2 of the rear waist portion 23 to the outside in the width direction W and pulling up the other side W2 of the absorber 13, the one side W1 and the other side W2 of the absorber 13 are brought into the inseam of the wearer. It can be adhered. In addition, it becomes easy to make the entire width direction of the absorbent body in the rear waistline region flat, and the absorbent body is arranged along the body, and the periphery of the leg opening on the outer side in the width direction than the absorbent body is provided to the wearer. Fits around the legs without any gaps.

  In addition, when the wearer's leg is passed through the first leg opening 32a and the crotch region S1 is aligned with the center of the wearer's body, the other side of the rear waist region S3 is pulled. The rear elastic region R62 extends. At this time, the crotch region S1 may move to the other side W2 as the rear elastic region R62 extends. According to such an absorbent article 1, in anticipation of its movement, the distance L13 in the width direction between the outer edge R62E1 on one side of the rear elastic region R62 and the center of the crotch region S1 is set to the other side W2 of the rear elastic region R62. By making it shorter than the distance L14 in the width direction between the outer edge R62E2 and the center of the crotch region S1, the crotch region S1 is prevented from moving too far to the other side W2, and the crotch region S1 is displaced from the center of the wearer's body. Can be suppressed.

  In a state where the absorbent article 1 is in close contact with the wearer's crotch, the wearing assistant covers the wearer's abdomen with the front waistline portion 22 of the absorbent article 1 and covers the fastening member 27 of the rear waistline portion 23 with the front waistline portion. 22 is fixed to the target portion 28 (FIG. 6E). 28 overlaps with the front-rear non-stretchable region and can maintain a state in which it does not contract in the front-rear direction L. Therefore, the fastening member 27 is easily attached to the target portion 28. Further, the target portion 28 may be in a state of being contracted in the width direction W by the second elastic member 63. When the fastening member 27 is fastened to the target portion 28, a force along the waist of the wearer is applied to the target portion 28 and the fastening member 27. By this force, wrinkles and kinks due to shrinkage in the width direction W in the target portion 28 are eliminated. When the fastening member 27 is fastened to the target portion 28, only a force along the width direction W is applied, and a force along the front-rear direction L or a force inclined with respect to the width direction W is difficult to be applied. Therefore, unintentional wrinkles and kinks in the target portion 28 are suppressed when the fastening member 27 is fastened, and the fastening member 27 is fastened to the flat target portion 28 to maintain the fastened state. It becomes easy. In the absorbent article 1, the front waistline portion 22 of the exterior body 20 is not provided with an elastic member that expands and contracts in the front-rear direction L, and the front waistline portion 22 expands and contracts only along the width direction W. Therefore, the length in the front-rear direction L of the front waistline portion 22 is suppressed from being shortened during mounting, and the fastening member 27 can be stopped on the target portion 28 in a flat state. By maintaining the target portion 28 in a flat state, a contact area between the target portion 28 and the fastening member 27 can be secured, and a decrease in bonding strength can be suppressed. By securing the bonding strength between the target portion 28 and the fastening member 27, it is possible to prevent the fastening member 27 from being unintentionally detached from the target portion 28. In addition, since the target part and the fastening member are subjected to a force along the waist of the wearer, and it is difficult to apply a force along the front-rear direction or a force inclined with respect to the width direction, the fastening member is attached to the target part. After that, due to the elastic stress in the first waistline region, each other is a force along the width direction and is pulled in the opposite direction. Therefore, the tip of the fastening member can easily enter the target portion, and the fastening state can be easily maintained.

  The wearing assistant pulls the rear waistline region S3 to the other side when the fastening member 27 is fastened to the target portion 28. Therefore, the rear waist region S3 is in close contact with the wearer's body even when the rear elastic region R62 has a relatively low expansion / contraction rate and the rear waist region S3 is not in close contact with the wearer's body in the natural state. Since the disposable diaper according to the present embodiment has one side joined by the side joining portion and has the first elastic member and the second elastic member, the wearing assistant pulls the fastening member along the width direction. Thus, the first elastic member can be interlocked to pull not only the other side but also the one side, and can pull not only the rear waistline but also the front waistline. By having the interlocking property of the elastic member in this way, the disposable diaper used only for the operation of pulling the fastening member with respect to both the leg circumference and the waist circumference of the wearer can be brought along the body.

  According to such a wearing mode, the wearing assistant wears the absorbent article on the wearer by changing the body posture twice, that is, the posture change from the supine to the sideways and the posture from the sideways to the supine. Can do. Therefore, it is possible to reduce the number of changes in the position of the wearer at the time of wearing, and to reduce the burden on the wearing assistant and the wearer by repeatedly changing the position. Moreover, as for the absorbent article 1 mounted in this way, the rear elastic region R62 and the front elastic region R63 are separated from the absorber arrangement region, and the width of the absorber 13 can be suppressed. Therefore, the absorbent article is attached to the wearer with the width of the absorbent body 13 secured. Moreover, the elastic member is arrange | positioned in the whole area | region from the waist opening part formed by the front-end edge and back end edge of a disposable diaper to a leg periphery opening part, and the elastic force is effective in the circumferential shape along a waist periphery. Therefore, even if the wearer moves, the disposable diaper can follow both the leg circumference and the waist circumference of the wearer, and the uncomfortable feeling at the time of wearing can be reduced.

  The inclined portion of the elastic member is disposed so as to straddle both outer edges 13E of the absorber 13 in the rear waistline region S3, and is disposed so as not to straddle both outer edges 13E of the absorber 13 in the front waistline region S2. . Therefore, the outer edge 13E of the absorbent body 13 in the front waistline region S2 is unlikely to generate contraction force so as to be directed inward in the width direction W and toward the crotch region S1. If the absorbent body 13 in the front waistline region S2 contracts so as to be directed inward in the width direction W and toward the crotch region S1, the outer edge 13E of the absorbent body 13 is not disposed along the heel portion of the body, and body fluid leaks. It leads to. In order to prevent such leakage, it is conceivable that the attachment assistant stops the fastening member 27 in a state where the absorber 13 in the front waistline region S2 is extended. However, generally, when the fastening member 27 is stopped, the wearer is lying on his / her back as shown in FIG. Therefore, in order to maintain the stretched state of the absorbent body 13 in the front waistline region S2, the wearing assistant pulls the absorbent body 13 in the front waistline region S2 outward in the width direction and pulls so as to maintain the state. Need to continue. However, since the inclined portions are arranged so as not to straddle both outer edges 13E of the absorber 13 in the front waistline region S2, the wearing assistant does not continue to stretch the absorber, and the absorber of the front waistline region The absorbent article can be worn in a state where the entire area is along the wearer's body. On the other hand, the rear waistline region S3 is in a state in which the absorber 13 in the rear waistline region S3 is stretched by pulling the other side of the absorbent article 1 during mounting. At this time, since the wearer is generally lying on his / her back, the absorbent article 1 is sandwiched between the body and the bedding and can maintain the stretched state of the absorbent body 13 in the rear waistline region S3. Therefore, even in the configuration in which the inclined portions are arranged so as to straddle both outer edges 13E of the absorbent body 13 in the rear waistline region S3, the absorber in the rear waistline region S3 without the wearing assistant continuously extending the absorbent body 13 The absorbent article 1 can be worn in a state where the entire region of 13 is along the wearer's body.

  Further, using a conventional tape-type disposable diaper, a leg-hole opening on one side of a tape-type disposable diaper is formed, and the leg-hole opening on the other side is opened, as in this embodiment. It is conceivable that a wearing assistant wears the wearer. However, when a tape-type disposable diaper is mounted in the same manner as the single-open type disposable diaper shown in the present embodiment, the following problem occurs. When the leg opening is formed on one side of the tape-type disposable diaper, the fastening member of the rear waist is fastened on the target of the front waist around the leg opening. Therefore, a region in which the front waistline portion and the rear waistline portion are stacked is provided around the leg opening. If the absorbent article is pulled up toward the wearer's waist through one leg through the leg opening, the portion where the front waistline and the back waistline are stacked will be shifted, and the front waistline and the back waistline will be wrinkled. May occur, or the wearer may rub against the wearer. Moreover, in order to suppress the shift | offset | difference of the part by which the front waistline part and the back waistline part were laminated | stacked, shifting the fastening position of the fastening member with respect to the target of a front waistline part, an absorbent article with respect to a wearer's body It can be placed loosely. However, when the absorbent article is loosely attached to the wearer's body, the position of the absorbent body and the wearer's body is shifted, the position of the side joint is shifted, It is necessary to change the posture repeatedly. By repeatedly changing the posture, it is necessary to repeatedly fasten the fastening member, so that the absorbent article cannot be easily attached, and the physical and mental loads of the wearing assistant and the wearer are increased. Furthermore, when the disposable diaper is loosely attached, the elastic force is difficult to act, and the disposable diaper does not follow the wearer's legs and waists, thus causing leakage. On the other hand, the single-open disposable diaper shown in the present embodiment has a side joint portion formed on one side and the front waistline portion and the rear waistline portion are not laminated on one side, so that the absorbent article can be smoothly The absorbent article can be changed by changing the posture with a small number of times.

  Moreover, as a use aspect of an absorbent article, not only the aspect which replace | exchanges the whole absorbent article but an absorption pad can be arrange | positioned inside an absorbent article, and only an absorption pad can be replaced | exchanged after use. FIG. 8 is a view for explaining an exchange mode of the absorbent pad arranged in the absorbent article.

  The wearing assistant turns the wearer sideways so that the leg on the side inserted into the second leg-hole opening 32b faces upward, removes the fastening member from the target portion, and deploys the other side of the absorbent article 1. (FIG. 8 (a)). Since the second leg-hole opening 32b side of the absorbent article 1 is opened, the wearing assistant can take out the absorbent pad through the opening. Next, the wearing assistant places the absorbent article 1 so as to cover the absorbent pad 80 after applying the new absorbent pad 80 to the wearer's body. At this time, the wearing assistant arranges the center in the width direction of the body so that the width center line 13WL of the absorber 13 is aligned (FIG. 8B). With the absorbent pad 80 disposed along the wearer's body, the wearing assistant pulls the other side W2 of the rear waistline portion 23 outward in the width direction W to extend the rear elastic region R62 (FIG. 8C )). At least the other side W2 of the rear waistline region S3 is in close contact with the wearer's body as the rear elastic region R62 extends. Next, the wearing assistant turns the wearer on his back (FIG. 8D). After adjusting the position of the absorbent pad 80 disposed in the front waistline region S2, the wearing assistant pulls the other side W2 of the front waistline portion 22 to the outside in the width direction W to extend the front elastic region R63 (FIG. 8). (E)). At least the other side W2 of the front waistline region S2 is in close contact with the wearer's body as the front elastic region R63 extends. In a state where the absorbent article 1 is in close contact with the wearer's body, the wearing assistant fastens the fastening member 27 of the rear waistline portion 23 to the target portion 28 of the front waistline portion 22 (FIG. 8E).

  According to such an exchange mode, when only the absorbent pad 80 is exchanged, an opening for taking in and out the absorbent pad 80 is formed on the other side by removing the fastening member 27, so that one leg of the wearer The absorbent pad 80 can be exchanged in a state where is inserted into the first leg opening 32a. Moreover, the wearing assistant can exchange the absorbent pad by changing the body position twice, that is, changing the body position from side to side and changing the body position from side to side. Therefore, it is possible to reduce the burden on the wearing assistant and the wearer by repeatedly changing the posture.

  Moreover, since the length of the 1st leg periphery opening part 32a is shorter than the length of the 2nd leg periphery opening part 32b, the 1st leg periphery opening part 32a tends to closely_contact | adhere to a wearer's leg periphery. When the wearer moves or moves the absorbent article 1 at the time of replacement, the absorbent article 1 is prevented from moving unintentionally, and the work of attaching the absorbent article 1 and the work of replacing the absorbent pad 80 are performed smoothly. Can proceed. Moreover, since the opening part 32b around the second leg is relatively wide, an opening for taking in and out the absorption pad 80 can be formed wide, and the replacement work of the absorption pad 80 can be smoothly advanced.

(3) Modification In the modification, the 3rd elastic member 62 and the 2nd elastic member 63 may be arrange | positioned in the area | region which overlaps with an absorber. In the modified example, the elongation rates of the third elastic member 62 and the second elastic member 63 disposed in the region overlapping with the absorber are set to the third elastic member 62 and the second elastic member disposed in the region not overlapping with the absorbent main body. It is preferable to make it lower than the member 63. Examples of the configuration for reducing the elongation rate of the elastic member include cutting of the elastic member and application of heat and ultrasonic waves.
