The front body first extension restraining portions 21 and 22 at the waist part of the front body 2 or the back body 3 when the specific load is applied in the vertical direction (Y direction) of the pad holder 1 It is the part made smaller than the part located in at least one of the both sides on both sides. The former is preferable from the viewpoint of detachability and wearing feeling.

  The lateral extension suppressing portions 11 and 12 have a maximum extension rate in the vertical direction (Y direction) of the pad holder on both sides of the side extension suppressing portions 11 and 12 in the waist portion of the front body 2 or the back body 3. The side at which the stretch rate when the specific load is applied in the longitudinal direction (Y direction) of the pad holder 1 is the waist part of the front body 2 or the back body 3 is made smaller than the part located at least one side It is a part made smaller than the part located in at least one of the both sides on both sides of the direction expansion suppression parts 11 and 12. The former is preferable from the viewpoint of detachability and wearing feeling.

The front body second extension suppressing unit 20 (the same applies to the rear body second extension suppressing unit 30 of the back body 3 described later) has a maximum extension rate in the width direction (X direction) of the pad holder 1. 3, a specific load in the width direction (X direction) of the pad holder, or in the width direction (X direction) of the pad holder. This is a portion where the elongation rate when the is added is smaller than the portion located on at least one of both sides (up and down) sandwiching the front body second stretch suppressing portion in the waist part of the front body 2 or the back body 3. In addition, when the front body 2nd expansion | extension suppression part 20 and the front body 1st expansion | extension suppression parts 21 and 22 cross | intersect, the maximum expansion | extension rate of the width direction or the said expansion | extension rate is the front body 1st expansion | extension suppression part 21. , 22 is smaller in the front body second extension suppression unit 20, and the maximum longitudinal extension rate or the extension rate is smaller in the front body first extension suppression unit 21, 22 than in the front body second extension suppression unit 20. preferable.
The maximum elongation rate is the elongation rate when the material is stretched to a length that cannot be further stretched (the length immediately before material breakage), and the maximum elongation rate is obtained by the following formula (1).
Maximum elongation rate (%) = {(length after stretching−length before stretching) / length before stretching} × 100% (1)

The maximum elongation rate in the longitudinal direction of the front body first elongation suppressing portions 21 and 22 is preferably less than 180%, more preferably 20 to 150%, and even more preferably 40 to 120%.
The maximum extension rate in the longitudinal direction of the lateral extension suppressing portions 11 and 12 is preferably less than 180%, more preferably 20 to 150%, and still more preferably 40 to 120%.

Is preferably 150% or more, more preferably 180% or more, and the difference from the maximum elongation rate of the first body first elongation suppressing portions 21 and 22 is preferably 30% or more, particularly 50 to 150%. Furthermore, it is preferable that the difference from the maximum extension rate of the lateral extension suppressing portions 11 and 12 is 30% or more, particularly 50 to 150%.
Moreover, it is preferable that the maximum expansion | extension rate of the width direction of the front body 2nd expansion | extension suppression part 23-26 is less than 200%, 50-180% is more preferable, 70-160% is still more preferable. For example, the maximum elongation rate (X direction) of each of the highly stretchable portions in the width direction positioned above and below the second body stretching restrainers 23 to 26 is determined by the ease of attaching and detaching the pad holder, the feeling of wearing, and the absorbent pad. 160% or more, particularly 180% or more, particularly 200% or more from the standpoint of the retaining property of the front body, and the difference from the maximum elongation rate of the front body second elongation suppressing portions 23 to 25 is 20% or more. In particular, it is preferably 30 to 130%.

  Further, the pad holder 1 is 35% or more, more preferably 50% or more, and still more preferably 65% or more of the total area (the total area of the outer surface or the inner surface) in the natural state from the front body stretch suppressing portion 21 (22). It is preferable that the portion has a high extensibility, that is, a portion having a larger maximum elongation rate, from the viewpoint of ease of attaching and detaching the pad holder and a feeling of wearing. The total elongation suppressing part is preferably 35% or more, particularly 50% or more of the total area.

It is preferable from the viewpoints of pulling-up property during operation and stable holdability of the absorbent pad. The same applies to the rear body first extension suppressing portions 31 and 32 described later. It is preferable from the same viewpoint that the area of the front body second elongation suppressing portions 23 to 26 is 6% or more and less than 20%, particularly 8% or more and less than 15% with respect to the area of the front body. In addition, it is the same also about the area of each back body 2nd expansion | extension suppression part 35-38. Moreover, it is preferable from the same viewpoint that the area of the lateral extension suppressing portions 11 and 12 is 2% or more and less than 30%, particularly 3% or more and less than 15%, and further 3% or more and less than 10% of the total area.

The maximum extension rate of the front body first extension suppression units 21 and 22 is measured by extending the front body first extension suppression units 21 and 22 in the longitudinal direction (Y direction) of the pad holder 1.
Similarly, the maximum extension rate of the side extension suppression units 11 and 12 is also measured by extending the side extension suppression units 11 and 12 in the longitudinal direction (Y direction) of the pad holder 1.
The maximum extension rate of the front body second extension suppressing unit 20 is measured by extending the front body second extension suppressing unit 20 in the width direction (X direction) of the pad holder.
On the other hand, the maximum elongation rate (Y direction) of the longitudinally high stretchable portions other than the front body first stretch restraining portions 21 and 22 and the lateral stretch restraining portions 11 and 12 is such that the highly stretchable portion Measurement is performed by extending in the direction (Y direction).
The maximum elongation ratio (X direction) of the width direction highly extensible portion other than the front body second elongation suppressing portions 23 to 26 is measured by extending the highly extensible portion in the width direction (X direction) of the pad holder. .

[Maximum elongation rate measurement method of the front body first elongation suppression units 21, 22 or the lateral elongation suppression units 11, 12]
From the pad holder to be measured, in the natural state, it is a rectangular shape with dimensions of 100 mm in the vertical direction (Y direction) and 50 mm in the width direction (X direction), and the center of the measurement sample in the longitudinal direction (equivalent to the Y direction) Are cut out so as to include the front body first extension suppressing parts 21 and 22 or the side extension suppressing parts 11 and 12 over a range of at least 60 mm, and the cut out rectangular shape is used as a measurement sample. In addition, although the said sample adjustment method presupposes that the front body 1st expansion | extension suppression parts 21 and 22 or the side expansion | extension suppression parts 11 and 12 are arrange | positioned continuously over the full range of 60 mm, front body 1st The case where the 1 stretch suppression part 21 or 22 or the lateral stretch suppression part 11 or 12 is divided at a part thereof and intermittently includes a longitudinally highly stretchable part is also included in this category.
The measurement sample is attached to a chuck of a tensile tester so that the longitudinal direction (corresponding to the Y direction) is the tensile direction. At this time, it is confirmed that the front body first extension suppressing parts 21 and 22 or the side extension suppressing parts 11 and 12 are sandwiched between the upper and lower chucks. The distance between chucks is 50 mm (the chuck part is a part 25 mm before and after the measurement sample). The measurement sample is pulled at 300 mm / min, and the distance between chucks is measured when at least a part of the measurement sample is broken.
However, when the sample for measurement does not break even after 100N load, the distance between chucks at 100N load is measured.
When the measurement sample cannot be taken out from the pad holder to be measured as described above, the sample length, the sample width, the distance between chucks, and the chuck width may be appropriately changed.

  The method for measuring the maximum elongation rate (Y direction) of the longitudinally highly extensible portions other than the front body first elongation suppressing portions 21 and 22 and the lateral elongation suppressing portions 11 and 12 is the same as described above. However, when cutting out the measurement sample, the measurement sample does not include the front body first extension suppression units 21 and 22 and the lateral extension suppression units 11 and 12. However, the front body second extension suppressing unit 20 may be partially included in the measurement sample.

[Measurement method of the maximum elongation rate of the front body second elongation suppression unit 20]
From the pad holder to be measured, in the natural state, it has a rectangular shape with dimensions of 100 mm in the width direction (X direction) and 50 mm in the longitudinal direction (equivalent to the Y direction), and the longitudinal direction of the measurement sample (equivalent to the X direction). In the center, at least one front body second elongation suppressing portion 23 to 25 is cut out so as to be included over a range of at least 60 mm, and the cut out rectangular shape is used as a measurement sample. The sample preparation method is based on the premise that the front body second extension suppressing units 23 to 26 are continuously arranged over the entire length of 60 mm. Forms that are partly divided and include a highly extensible portion in the width direction are also included in this category.
The measurement sample is attached to a chuck of a tensile tester so that the longitudinal direction (corresponding to the X direction) is the tensile direction. At this time, it is confirmed that at least one of the front body second extension suppressing portions 23 to 26 is sandwiched in any of the upper and lower chucks. The distance between chucks is 50 mm (the chuck part is a part 25 mm before and after the measurement sample). The measurement sample is pulled at 300 mm / min, and the distance between chucks is measured when at least a part of the measurement sample is broken.
However, when the sample for measurement does not break even after 100N load, the distance between chucks at 100N load is measured.
If the sample cannot be taken out from the pad holder to be measured as described above, the sample length, sample width, distance between chucks, and chuck width may be changed as appropriate.

  The method for measuring the maximum elongation rate (width direction) of the highly stretchable portion in the width direction other than the front body second stretch suppression portions 23 to 26 is the same as described above. However, when the measurement sample is cut out, the front body second extension suppressing portions 23 to 26 are not included in the measurement sample. However, the front body first extension suppressing parts 21 and 22 or the side extension suppressing parts 11 and 12 may be partially included in the measurement sample.

In addition, the front body first extension restraining portions 21, 22 indicate that “the front body first is in the waist part of the front body 2 or the back body 3 when the specific load is applied in the longitudinal direction (Y direction) of the pad holder 1. “It is made smaller than at least one part on both sides of the stretch suppression portions 21 and 22”, assuming that the excrement is held by the pad in a normal wearing state, at the time of 3N weighting It means that the elongation rate is small when compared with the elongation rate. The preparation method and measurement method of the measurement sample are performed according to the measurement method of the maximum elongation rate except for the weighted value. The concept is the same for the extension rate when the specific load of the side extension suppressing units 11 and 12 or the front body second extension suppressing unit 20 is applied.
The widths of the front body first extension restraining parts 21 and 22, the side extension restraining parts 11 and 12, and the front body second extension restraining part 20 are not particularly limited. For example, the width of the illustrated example is about 0.5 to 5 cm. is there.

  In the pad holder 1 of the present embodiment, as shown in FIGS. 1 to 4, the pair of front body first extension restraining portions 21 and 22 are arranged from the center region 2C in the width direction of the lower half 2D of the front body to the upper half of the front body. It extends over both the left and right side parts of the part 2U, and in the width direction side regions 2L and 2R, the pair of lateral extension suppressing parts 11 and 12 are crotch parts of the front body first extension suppressing parts 21 and 22, respectively. It extends along the substantially vertical direction (Y direction) on the 4 side. When worn by the front body first extension restraining parts 21 and 22 and the side extension restraining parts 11 and 12 extending along the longitudinal direction (Y direction), the crotch part 4 and the side in the width direction are worn. Since the regions 2L and 2R are pulled up at the same time, the entire periphery of the leg openings 6 and 6 is pulled up without being left behind, and the combined absorbent pad 7 can be easily fitted to the wearer's crotch. A feeling of wearing can be improved and the detachability at the time of wearing can also be improved. When wearing, the pair of front body first extension restraining parts 21 and 22 stabilize the shape of the pad holder 1, and the pair of side body extension restraining parts 11 and 12 are connected to the front body first extension restraining part 21, Since 22 is located on the crotch 4 side, the entire peripheral portions of the leg openings 6 and 6 can be efficiently pulled up without distortion of the lateral extension suppressing portions 11 and 12.

  Moreover, as shown in FIGS. 1-4, the pad holder 1 of this embodiment has the waist opening elastic part 51 and the front body 1st expansion | extension suppression parts 21 and 22 arranged at intervals, and the front body The first extension suppressing units 21 and 22 and the side extension suppressing units 11 and 12 are arranged with an interval therebetween. That is, in the front body 2, with respect to the longitudinal direction (Y direction) of the pad holder 1, between the waist opening elastic part 51 and the front body first extension suppressing parts 21 and 22, and the front body first extension suppressing parts 21 and 22; Between the side extension suppression parts 11 and 12, the area | region where extensibility is higher than the front body 1st extension suppression parts 21 and 22 and the side extension suppression parts 11 and 12 exists. This configuration allows the pad holder 1 to follow the expansion and contraction of the skin particularly when the posture changes (for example, forward bending, standing and sitting), and prevents slipping while wearing the pad holder 1 as well as during exercise and deep breathing. Even if it exists, the freedom degree of an abdomen is ensured and comfort is maintained. In addition, since the region having high extensibility absorbs the amount of extension of the skin during activities such as walking, it is possible to prevent activity inhibition caused by the accompanying pad holder 1. Further, the slip suppression by the extension suppressing portions 21 and 22 makes it possible to suppress the pad holder from slipping even if the tightening of the waist portion by the waist opening elastic portion 51 is weakened. And tightening marks can be reduced.

In addition, as shown in FIG. 5, the pad holder 1 of the present embodiment has a pair of lateral extension suppressing portions 11 and 12 in the longitudinal direction with the width across the folding lines 1a and 1a in the entire region ( (Y direction) extends in a band shape. The folding lines 1a and 1a having the longest distance between the front body first extension restraining portions 21 and 22 and the leg opening portions 6 and 6 are portions that are most easily stretched when worn, but a pair of side stretch restraining portions 11 and 11 12, the folding lines 1a and 1a can be efficiently pulled up.
From the viewpoint of efficiently pulling up the folding lines 1a and 1a, the pair of side extension suppressing parts 11 and 12 has the folding lines 1a and 1a at 70% or more of the total length of the pair of side extension suppressing parts 11 and 12, respectively. It is preferable to straddle, and it is more preferable to straddle the folding lines 1a, 1a in the whole area, that is, to arrange on the folding lines 1a, 1a in the whole area.
The width of each of the pair of lateral extension suppressing portions 11 and 12 may be different in each part in the longitudinal direction, but is substantially the same in each part in the longitudinal direction from the viewpoint of efficiently raising the folding lines 1a and 1a. It is preferable that

  Further, in the pad holder 1 of the present embodiment, the portions 21c and 22c of the pair of front body first extension restraining portions 21 and 22 have the upper anterior iliac spine 81 of the wearer when worn as shown in FIG. Since it is formed in a band shape so as to be located above (upper side in FIG. 2), when the pad holder 1 is worn due to an increase in the weight of the absorbent pad 7 due to liquid absorption, etc., there is a force to pull down the pad holder 1 downward. Even if it works, the front body first extension restraining parts 21 and 22 are hooked on the upper anterior iliac spines 81 and 81, and the front body first extension restraining parts 21 and 22 are made of a stretchable sheet. Since the movement of the crotch part 4 downward is suppressed against the elongation of the crotch part, it is possible to effectively prevent the absorbent pad 7 and the pad holder 1 from sliding down. When the absorption capacity of the absorbent pad 7 is large, for example, when the absorption capacity (measured with physiological saline) is 250 mL or more, or 300 mL or more, the pulling force by the absorbent pad 7 is increased. Even so, the absorbent pad 7 can be held (held) in a state fitted to the wearer's crotch by the action of the front body first extension suppressing portions 21 and 22. In the form in which such an extension suppressing portion does not exist, it is necessary to prevent slipping by the waist elastic member, and it is necessary to devise such as increasing the tightening force. Then, it can be eased and resolved.

  Moreover, the pad holder 1 of this embodiment has the front body 2nd expansion | extension suppression part 20 extended in the width direction (X direction) of a pad holder in the front body 2, The front body 2nd expansion | extension suppression part 20 is The front body crosses the first extension restraining portions 21 and 22 and is in contact with the lateral extension restraining portions 11 and 12. In this way, the front body second extension restraining part 20 extends between the front body first extension restraining parts 21 and 22, so that the front body first extension restraining parts 21 and 22 that function like pillars are connected to the front body. Even if the second stretch suppression unit 20 is supported and the weight of the absorbent pad 7 increases due to liquid absorption, the front body second stretch suppression unit 20 acts like a hammock, and the front body second stretch suppression unit. It can suppress effectively that 20 hangs down. Thereby, the absorptive pad 7 can be hold | maintained in the state fitted well to a wearer's crotch part. In the present embodiment, the front body second extension suppressing unit 20 intersects with the front body first extension suppressing units 21 and 22 and further extends until it contacts the side extension suppressing units 11 and 12. Around this time, it is possible to more effectively suppress the second extension suppressing portion 20 from sagging. Even during activity, at least two or more front body second extension suppression parts 20 are the front body first extension suppression part 21 from the viewpoint of keeping the absorbent pad 7 in a state of being well fitted to the wearer's crotch part. , 22, and further extend to contact with the lateral extension suppressing portions 11, 12. Furthermore, it is more preferable that at least two or more front body second extension suppressing portions 20 are arranged in the front body lower half 2D. In particular, in this embodiment, the front body 2nd expansion | extension suppression part 20 consists of several front body 2nd expansion | extension suppression parts 23-26, The 3 front body 2nd expansion | extension suppression parts 23 and 24 in it are the inside. , 25 are in contact with the lateral extension suppressing portions 11 and 12, the force that the front body second extension suppressing portion 20 hangs down can be dispersed, so that the sag can be more effectively suppressed.

Further, the front body first extension restraining portions 21 and 22 extend from the width direction central region 2C side of the front body lower half 2D to the side of the front body upper half 2U, so that the front body 2 and / or Or, even when high extensibility is imparted to a wide range of the back body 3, there is a problem that when the pad holder 1 is pulled up and worn, the vicinity of the crotch part 4 of the holder is caught on the thigh and cannot be pulled up sufficiently. It is difficult to occur and the entire pad holder 1 can be easily pulled up to an appropriate position without reworking. At the time of lowering, when the wearer or a caregiver removes the front body first extension restraining portions 21 and 22 located on the upper anterior iliac spines 81 and 81 from the upper anterior iliac spines 81 and 81, The effect of suppressing the slipping by the extension suppressing units 21 and 22 is released, and can be easily pulled down.
In order to effectively prevent the absorbent pad 7 and the pad holder 1 from slipping downward, and the pad holder 1 can flexibly respond to changes in the abdominal circumference due to breathing or the like, It is preferable that at least the upper half 2U of the front body does not cross each other.

  As shown in FIG. 2, the pad holder 1 of the present embodiment includes portions 2 b and 2 c in which the portions covering the iliac crests 8 and 8 in the front body 2 are more extensible than the first body body first extension restraining portions 21 and 22. In addition, since the front body first extension suppressing portions 21 and 22 are positioned above the iliac crest, the vicinity of the boundary between the highly extensible portions 2b and 2c is easily caught by the iliac ridges 8 and 8. Therefore, the downward sliding of the absorbent pad 7 or the pad holder 1 can be more effectively prevented. In particular, when the portions covering the upper anterior iliac ridges 8 and 8 are stretchable, it is easy to follow the movement of the wearer during wearing, and the upper anterior iliac bone is caught when the front body extension restraining portions 21 and 22 are caught. This is preferable because the feel of hitting the ridge becomes soft.

  Moreover, the pad holder 1 of the present embodiment can effectively prevent the absorbent pad 7 and the pad holder 1 from slipping downward by the front body first elongation suppressing portions 21 and 22 described above. There is no need to place the elastic member along the wearer's ridge and press the pad holder against the ridge. Although it is possible to arrange an elastic member on the ridge, it is preferable not to tighten the ridge with an elastic member from the viewpoint of reducing irritation to the skin and good wearing feeling, especially for elderly people with weak skin preferable.

  Moreover, the front body 2nd expansion | extension suppression part 20 is arrange | positioned intermittently by multiple pieces (in this embodiment, the 4 front body 2nd expansion | extension suppression parts 23-26), and the longitudinal direction of the absorptive pad 7 is arranged. The position can be easily adjusted. And at least 1 of these, Preferably 2 or more are distribute | arranged to the front body lower half part 2D (In this embodiment, 3 front body 2nd expansion | extension suppression parts 24-26), an absorptive pad 7 stable fixation and good wearability can be obtained.

  It is preferable from the viewpoint of pad holding property and wearing feeling that the front body first extension suppressing portions 21 and 22 are always positioned above the crotch (near the crotch edge) and above the wearer's heel. In this case, since the front body first extension restraining portions 21 and 22 do not intersect with the heel portion, it is difficult for leg movements such as walking to be transmitted to the front body first extension restraining portions 21 and 22 through the heel portion. Since it becomes difficult to be transmitted to the front body 2nd expansion | extension suppression parts 23-25 through a front body 1st expansion | extension suppression part, it becomes easy for each expansion | extension suppression parts 21-25 to suppress position shift effectively. For this reason, it becomes easy to suppress the position shift of an absorption pad, and it becomes possible to suppress effectively that an uncomfortable feeling is produced in a ridge part and each expansion | extension suppression part contact part.

  In addition, the front body second extension suppressing portion 20 is an upper region of the front body upper half 2U (a side of the front body upper half 2U from the center in the Y direction of the front body upper half 2U toward the waist opening 5). It is preferable that it does not exist in this region. In the upper region of the upper half 2U of the front body, the effect of preventing distortion of the main body due to the displacement of the absorbent pad 7 by the front body second elongation suppressing portion 20 and the shaking of the absorbent pad 7 (the effect of the beam) is small. This is because a change in abdominal circumference is restricted, and the concern of giving a feeling of pressure to the wearer can be reduced.

  Further, in the pad holder 1 of the present embodiment, as described above, when wearing, a part of the iliac crest 8 of the wearer, more specifically, the uppermost part of the iliac crest 8 is suppressed from stretching the front body. It can be sandwiched between the portions 21 and 22 and the extended portion 23c of the front body second extension suppressing portion 23. The front body first extension restraining parts 21 and 22 and the extension part 23c of the front body second extension restraining part 23 surround a part of the iliac crest 8 (by being caught by the iliac crest 8), and the wearer The pad holder 1 is less likely to be displaced (up / down / left / right) even when standing or sitting or walking. In addition, since the displacement of the pad holder 1 is suppressed, the absorbent pad 7 is less likely to be displaced, which is preferable from the viewpoint of leakage prevention. Further, when the front body second extension suppressing unit 20 (in this embodiment, the front body second extension suppressing units 23 and 24) is present so as to place the upper anterior iliac spine 81 therebetween, the position of the pad holder 1 It is preferable because a shift (particularly a vertical shift) hardly occurs and the wear feeling is excellent. In addition, the front body 2nd expansion | extension suppression part 23 which has the extension part 23c continues to the back body 2nd expansion | extension suppression part 35 in the side part of the pad holder 1, as shown in FIG. It is preferable to form the surrounding cyclic | annular expansion | extension suppression part.

  In addition, in the pad holder 1 of this embodiment, as shown in FIG. 2, the opening peripheral part of a pair of leg opening parts 6 and 6 is located below the crotch part 4 when the pad holder 1 is worn. . The opening peripheral edge of the pair of leg openings 6 and 6 is positioned below a line (not shown) along the wearer's ridge, so that the absorbent pad can be held and exposed from the holder to the outside. It is preferable from the point of prevention. Further, it is preferable that an extension suppressing portion for suppressing extension in the width direction is not formed on the opening peripheral portion of the leg openings 6 and 6 having a large movable amount and a large difference in circumference between individuals. It is further preferable not to form an extension suppressing portion extending in the width direction within 3 cm from the opening peripheral edge of the openings 6 and 6.

  The front body first extension suppressing portions 21 and 22 in the pad holder 1 of the present embodiment are respectively tangent L (only one is shown) in a region from the front body lower half 2D to the side of the front body upper half 2U. The angle α (see FIG. 1) formed with a straight line extending in the width direction of the pad holder (for example, a straight line L21 that bisects the crotch length L2) gradually decreases as the side part of the upper half 2U of the front body approaches. It is formed in a circular arc shape. With such a configuration, it is prevented that load and strain are intensively applied to one point on the line of the extension suppressing portions 21 and 22, so that the extension suppressing portions 21 and 22 fit the wearer's body without gaps, and It is more easily caught on the iliac crests 8 and 8. Therefore, it is more excellent in wearing feeling and slip-off prevention.

  It is preferable that the front body first elongation suppressing units 21 and 22, the side elongation suppressing units 11 and 12 and the front body second elongation suppressing unit 20 do not include elastic yarn such as polyurethane elastic fiber (spandex). When the elastic yarn having shrinkage is included in the extension suppressing portion, when the front body first extension suppressing portions 21 and 22 and the front body second extension suppressing portion 20 intersect, the side extension is suppressed at the intersection. When the portions 11 and 12 and the front body second elongation suppressing portion 20 are in contact with each other, the tissue density (knitting tissue density in the case of a knitted fabric) is increased at the contact portion, and the tissue is likely to be hardened. When the elastic yarn is not included, such curing does not occur and irritation to the wearer's skin can be suppressed.

As shown in FIGS. 3 and 4, the pad holder 1 according to the present embodiment includes, in the back body 3, the back body first extension suppressing portions 31 and 32, the back body intermediate extension suppressing portions 33 and 34, and the back body second extension. A suppression unit 30 is provided.
More specifically, a pair of left and right rear body first extension restraining portions 31 and 32 extending from the center region 3C in the width direction of the lower half 3D of the back body toward the side of the upper half 3U of the back body, and the back body A pair of left and right rear body intermediate extension restraining portions 33, 34 extending from the lower half 3D toward the waist opening 5 are formed. The back body 2nd expansion | extension suppression part 30 extended in the width direction (X direction) of a pad holder is formed from the 4 back body 2nd expansion | extension suppression parts 35-38 in this embodiment.

  Here, the lower half 3D of the back body is a portion located below a straight line L31 that bisects the crotch length L3 of the back body 3 as shown in FIG. 3, as with the above-described lower half 2D of the front body. And the back body upper half part 3U is a part located above the same straight line L31 similarly to the front body upper half part 2U mentioned above. Further, the width direction central region 3C is the region located on the leftmost side when the back body 3 is divided into three equal parts on the left and right (width) as shown in FIG. Direction side region 3L) and a region located on the rightmost side (width direction side region 3R).

As shown in FIG. 4, the back body first extension suppressing portions 31 and 32 preferably pass over the recess 9 formed in the overlapping portion of the pelvic recess and the gluteal muscle group, preferably on the central portion of the recess 9. The pad holder 1 is formed so as to pass in a substantially vertical direction (Y direction). FIGS. 7A to 7C show a pelvis 91, a middle ankle muscle 92, and a greater ankle muscle 93 that overlap in this order from the inside to the outside (skin surface side) of the body. 7 (d) shows the position and approximate size of the depression 9 that can be formed in the overlapping portion of the pelvis 91 recess and the gluteal muscle group (the middle gluteal muscle 92 and the large gluteal muscle 93). The depression 9 can be formed by the insertion of the gluteal muscle group (the middle gluteal muscle 92 and the large gluteal muscle 93) into the concave portion of the pelvis 91.
It is effective that a gap is generated between the absorbent pad 7 and the skin by arranging the rear body first extension suppressing portions 31 and 32 so as to pass through the position of the center portion of the recess 9 of the buttocks. Can be prevented and leakage prevention is improved.

As shown in FIG. 3, the rear body first extension restraining portions 31, 32 are configured so that the end portions 31 a, 32 a on the back body upper half 3 U side face the pad holder 1 between the front body 2 and the back body 3. It is preferable to reach the folding lines 1a and 1a generated on the side portions of the holder when they are brought into a planar natural state by being in contact with each other. The end portions 31a and 32a may not reach the folding lines 1a and 1a, respectively, but in this case, the shortest distance to the folding lines 3a and 3a is preferably 30 mm or less, particularly 10 mm or less.
Further, as shown in FIG. 3, the end portions 31 a and 32 a of the back body first extension restraining portions 31 and 32 are located at the waist opening portion from the position of the back body second stretch restraining portion 35 described later closest to the waist opening portion 5. It extends to the 5th side (upper side).
Moreover, as for the back body 1st expansion | extension suppression part 31,32, as shown in FIG. 3, center part 3C of the width direction center area | region 3C in the back body lower half part 3D has end parts 31b and 32b by the side of the back body lower half part 2D. It is preferable to enter the region 41 between the pair of leg openings 6 and 6 near the line CL, and when the skin facing surfaces of the front body 2 and the back body 3 are brought into contact with each other to form a planar natural state It is more preferable that the folding line 1b generated at the crotch part 4 is reached.

As shown in FIG. 3, it is preferable that the end portions 33 a and 34 a on the waist opening 5 side are present in the upper half 3 U of the back body of the back body intermediate extension suppressing portions 33 and 34. However, the distance between the end portions 33a, 34a and the opening peripheral edge of the waist opening 5 is preferably 3 cm or more, particularly 5 cm or more. When the end portions 33a and 34a reach the waist opening elastic portion 51, the longitudinal (Y direction) stretchability of the back side pad holder is lowered, and there is a concern that the back side slips down. is there.
As shown in FIG. 3, the end portions 33 a and 34 a of the rear body intermediate extension suppressing portions 33 and 34 are in contact with a later-described rear body second extension suppressing portion 35 closest to the waist opening 5.

  As shown in FIG. 3, the rear body middle extension restraining portions 33 and 34 have end portions 33 b and 34 b on the lower back half 3D side closer to the center line CL than the center region 3 </ b> C in the width direction in the lower half 3D of the back body. The region 41 between the pair of leg openings 6 and 6 preferably penetrates into the region 41, and more preferably reaches the folding line 1 b generated in the crotch portion 4. The area of the back body intermediate restraining portions 33, 34 is 2% or more and less than 15%, particularly 4% or more and less than 10% of the back body area in the natural state of the pad holder. From the viewpoint of stable holdability of the absorbent pad.

  In the pad holder 1 of the present embodiment, the front body first extension restraining parts 21 and 22 of the front body 2 and the back body first extension restraining parts 31 and 32 of the back body 3 are the crotch part 4 and the side part of the wearer. It is connected by the site | part distribute | arranged to, and is continuing cyclic | annular as a whole. Thereby, since the expansion | extension suppression part continued cyclically | annularly is position-fixed by the pubic bone coupling | bond part and the upper anterior iliac spine 81, a slip-off is further suppressed. In particular, it is preferable from the viewpoint of the slip-off suppressing effect in a situation where the back body side is pulled more in a sitting posture or the like. Here, the pubic joint part is an anatomical term, and is a part where the pubic bones located on the left and right sides below the pelvis are joined at the crotch center.

As shown in FIG. 3, the four rear body second extension suppressing portions 35 to 38 of the rear body second extension suppressing portion 30 are formed to extend in the width direction (X direction) of the pad holder. Moreover, the back body 2nd expansion | extension suppression parts 35-38 are arrange | positioned intermittently in the vertical direction (Y direction) of a pad holder.
The back body second elongation suppressing portion 30 may have a shape such as a convex shape or a wave shape upward or downward. From the standpoint of pad retainability and fitability to the wearer, it is preferably linear or convex downward.

  The rear body second extension suppressing part 30 is formed between the pair of rear body first extension suppressing parts 31 and 32. More specifically, as shown in FIG. 3, three rear body second extension suppressing portions 35 to 37 out of the four rear body second extension suppressing portions 35 to 38 are arranged in the width direction of the pad holder ( In the X direction), it extends outward from the rear body first extension suppressing portions 31 and 32 until it contacts the side extension suppressing portions 11 and 12. On the other hand, as for the remaining one rear body second extension suppressing part 38, both ends in the width direction (X direction) are located at the positions of the rear body first extension suppressing parts 31 and 32.

The rear body first extension restraining portions 31 and 32 and the back body intermediate stretch restraining portions 33 and 34 have a lower maximum stretch rate in the longitudinal direction (Y direction) than other portions (highly extensible portions). The preferable extensibility of the 3rd, 4th expansion | extension suppression parts 31-34 is the same as that of the front body 1st expansion | extension suppression parts 21 and 22 mentioned above.
The back body second elongation suppressing part 30 has a lower maximum elongation rate in the width direction (X direction) than other portions (highly extensible portions). The preferable extensibility of the back body second elongation suppressing unit 30 is the same as that of the front body second elongation suppressing unit 20 described above.

  The distance W3 (see FIG. 3) between the back body first extension suppressing parts 31 and 32 and the back body intermediate extension suppressing parts 33 and 34 on the same left and right sides of the pad holder 1, that is, the back body first extension suppressing part 31 and The distance between the back body intermediate extension suppressing part 33 and the distance between the back body first extension suppressing part 32 and the back body intermediate extension suppressing part 34 is increased from the lower side to the upper side in the longitudinal direction (Y direction) of the pad holder 1. Gradually increasing. Thereby, while suppressing the center part (for example, part which has an absorptive core inside) by the back body 1st expansion | extension suppression part 31 and 32, back body intermediate | middle expansion | extension suppression part 33 and 34 absorbs. Both side portions of the pad 7 (for example, side flap portions extending from both side edges of the absorbent core) can be suppressed, and leakage prevention is improved. Moreover, since the space | interval W3 of the back body 1st expansion | extension suppression parts 31 and 32 and the back body intermediate | middle expansion | extension suppression parts 33 and 34 opens as it progresses to the waist opening part 5 side, the front and back are fan-shaped. Even with a pad, you can fit your skin firmly.

As the stretchable sheet including the stretchable member forming the pad holder 1 of the present embodiment, a knitted fabric, a stretchable nonwoven fabric or the like can be used. In particular, the yarn itself has stretchability and stretchability. It is preferable to use a knitted fabric formed by a knitting method that easily develops.
The pad holder 1 of the present embodiment is formed from a stretchy cylindrical knitted fabric manufactured by a circular knitting machine or the like, and is formed seamlessly without a joint joining the front body 2 and the back body 3. It is preferable. At the waist opening 5 of the pad holder 1 and the opening peripheral edge of the pair of leg openings 6, 6, the waist opening elastic part 51 and the waist opening elastic part 51 are obtained by folding back a predetermined width part from the end of the cylindrical knitted fabric. A leg opening elastic portion 61 is formed. Each extension suppressing part 21-26, 31-38 is reducing the maximum extension rate by making the mesh of the knitted fabric of those parts denser than other parts. As another forming method of the extension suppressing portions 21 to 26 and 31 to 38, for example, a method of joining a belt-like sheet inferior in extensibility to a sheet rich in stretchability by stitching, fusion bonding, or the like can be given.

In addition, the pad holder 1 of the present embodiment preferably has a width direction (X direction) stretching stress at a circumference of 100 cm of 5 to 40 N, particularly preferably 10 to 30 N, and the pad holder 1 in the vertical direction (Y direction) under a load of 750 g. ) Is preferably 175 to 500%, particularly preferably 200 to 300%. The circumference of 100 cm is an approximate value for expanding the waist when the wearer puts up, and the 750 g load is an approximate model value when the wearer pulls the waist when putting up.
The pad holder 1 is opened with a relatively low stress with the width direction (X direction) stretching stress in the above range, and moderate longitudinal elongation is developed with the elongation in the longitudinal direction (Y direction) within the above range. By doing so, it is possible to achieve an easy pulling property. However, the deterioration of the slip-off property is unavoidable only by this, but by providing the extension suppressing portions 21 to 26 and 31 to 38 as in the present invention, it is possible to achieve both the pulling-up property and the slip-off preventing property. .

[Measurement method of stretching stress in width direction (X direction) at 100cm circumference]
A pad holder to be measured is bridged between a pair of U-shaped jigs and fixed between chucks of a tensile tester (for example, “RTA-100” manufactured by Orientec Co., Ltd.). In the initial state, the pad holder is set to a natural state (a state in which no external force is applied). Then, the pad holder fixed between the chucks is extended at 300 mm / min, and the stress when the distance between the left and right sides of the pad holder becomes 50 cm is referred to as “width direction (X direction) stretching stress at 100 cm circumference”. To do.

[Measurement method of longitudinal elongation at 750g load]
In the natural state, a rectangular shape having a size of 100 mm in the vertical direction (Y direction) and 50 mm in the width direction (X direction) is cut out from the pad holder to be measured, and this cut out rectangular shape is used as a measurement sample.
The measurement sample is attached to a chuck of a tensile tester so that the longitudinal direction (corresponding to the Y direction) is the tensile direction. The distance between chucks is 50 mm (the chuck part is a part 25 mm before and after the measurement sample). The measurement sample is pulled at 300 mm / min and stopped when a 750 g (7.4 N) load is indicated. The distance between the chucks at that time is measured, and “the elongation in the longitudinal direction (Y direction) under a load of 750 g” is calculated from the following equation.
Elongation (%) = {(Distance between chucks during extension (mm) / Distance between initial chucks 50 mm} × 100

As mentioned above, although this invention was demonstrated based on the preferable embodiment, this invention is not restrict | limited to embodiment.
