  In the conventional boxer brief type pad holder as disclosed in Patent Document 1, it is difficult to stably fit the absorbent pad used together with the wearer's crotch, and the wearer's skin and absorbent pad In some cases, leakage occurs through the gap, or the absorbent pad bends in the gap formed between the wearer and the absorbent pad, resulting in leakage. Moreover, according to the pad holder disclosed in Patent Document 2, the absorbent pad can be satisfactorily fitted to the wearer's crotch, but there is room for improvement in terms of improvement in pad retainability and wearing feeling. . Further, since the gathering member is provided with elasticity to the sheet material by fixing the elastic member to the sheet material in a stretched state, in a natural state, the portion where the elastic member is disposed is the elastic member. In general, the extensibility is higher than the portion where no member is arranged. Furthermore, with the structure of the brief as disclosed in Patent Document 3, the effect of improving the fit and slip-off prevention properties of the absorbent pad is insufficient.

It is a front view (figure 1 equivalent figure) which shows other embodiment of the pad holder of this invention. FIG. 7 is a rear view (corresponding to FIG. 3) of the pad holder shown in FIG. 6.

Hereinafter, the pad holder of the present invention will be described with reference to the drawings based on preferred embodiments thereof.
The pad holder 1 according to an embodiment of the present invention has a waist region A and a main body portion H, and substantially the entire main body portion H is stretchable.
As shown in FIG. 1, the pad holder 1 has a pant-type configuration and includes a waist opening 5 and a pair of leg openings 6 and 6. The pad holder 1 has a front body 2 disposed on the wearer's abdomen when the pad holder 1 is worn, and a back body 3 disposed on the wearer's back when the pad holder 1 is worn. Yes.
The waist region A is a range from the opening peripheral edge of the waist opening 5 to a position 5 cm below, and the main body portion H is a portion positioned below the waist region A.
The main body portion H is composed of a cylindrical waistline portion arranged around the wearer's waist when worn, and two tubular thigh regions C arranged around the wearer's legs when worn. The waist part includes a waist part B on the front body 2 side and a waist part D on the back body 3 side.
As shown in FIG. 1, the pad holder 1 is formed symmetrically with respect to a center line CL extending in the vertical direction of the pad holder.

The pad holder 1 is worn in a state in which an absorbent pad 7 is disposed on the skin facing surface of the crotch part 4 (surface directed toward the wearer's skin when the pad holder is worn) as shown in FIGS. Is done. The crotch part 4 is a part disposed in the crotch part of the wearer when worn.
The absorbent pad 7 generally includes a liquid-permeable top sheet, a liquid-impermeable or water-repellent back sheet, and an absorbent core sandwiched and fixed between the two sheets. The absorbent pad 7 may or may not have a fixing means (such as an adhesive portion) for fixing to the pad holder 1 on the surface on the back sheet side.

The waist opening 5 is a portion through which the waist portion of the wearer is inserted, and a waist opening elastic portion 51 is formed in an annular shape at the periphery of the opening. Moreover, a pair of leg opening parts 6 and 6 are parts through which a wearer's leg is penetrated, and the leg opening elastic part 61 is formed cyclically | annularly in each opening peripheral part.
The waist opening elastic part 51 expands and contracts in the circumferential direction of the waist opening 5. The leg opening elastic part 61 expands and contracts in the circumferential direction of the leg opening 6.
The waist opening elastic part 51 in this embodiment is formed by arranging a waist part elastic member in the opening peripheral part of the waist opening part 5. As shown in FIG. Moreover, the leg opening elastic part 61 in this embodiment is formed by arranging a leg part elastic member in the opening peripheral part of the leg opening part 6. FIG. The waist elastic member and the leg elastic member may be attached to the elastic sheet constituting the pad holder 1 or may be attached to the edge of the elastic sheet so as to extend from the edge. good.
As a waist part elastic member and a leg part elastic member, the elastic woven fabric and nonwoven fabric containing a polyurethane fiber, a synthetic rubber sheet, a natural rubber sheet etc. are used, for example. The elastic members used in the leg opening elastic part 61 and the waist opening elastic part 51 may be the same or different.
The waist opening elastic part 51 and the leg opening elastic part 61 are formed by folding the elastic sheet constituting the pad holder and fixing its end to the holder inner surface (or outer surface) instead of overlapping each elastic member. You can also

  Due to the presence of the waist opening elastic portion 51, the opening peripheral edge portion of the waist opening portion 5 can tighten the wearer more strongly than the annular portion made only of the elastic sheet existing immediately below when the pad holder 1 is worn. it can. Similarly, the opening peripheral part of each leg opening part 6 and 6 can tighten a wearer strongly compared with the annular part which exists immediately above this opening peripheral part in each leg opening part 6. FIG.

  The pad holder of the present invention exhibits stretchability at least in the width direction of the pad holder (direction perpendicular to the longitudinal direction of the pad holder, direction along the waistline direction). In the longitudinal direction of the pad holder (the direction from the waist opening toward the crotch), it is not necessary to have stretchability, and it is only necessary to exhibit extensibility. However, it has vertical stretchability (especially the buttocks to the back waist), making it easier for the holder to follow the elongation of the skin near the buttocks due to movements such as walking and standing and to suppress the occurrence of slipping. This is preferable. Moreover, it is preferable from the point that it becomes easy to follow a complex shape having irregularities such as the abdomen (particularly the abdomen of the elderly) and the buttocks and the like, and the fitting property is good.

As shown in FIG. 1, the front body 2 of the pad holder 1 has a pair of left and right front body first extension suppressing portions 21 and 22 from the crotch region b2 to both side edges 1a and 1a of the body region b1, respectively. It is formed to extend. The front body first extension suppressing portion is a portion formed in the front body of the pad holder, in which the stretchability in the pad holder vertical direction is suppressed.
As shown in FIG. 1, the crotch region b2 is below a straight line L21 that bisects the length (measured on the center line CL) between the waist region A and the lower end 1b of the crotch region in the front body 2. The body region b1 is a portion located below the waist region A and above the straight line L21.
As shown in FIG. 1, the side edges 1a and 1a of the body region b1 are formed when the pad holder 1 is brought into a flat natural state by contacting the skin facing surfaces of the front body 2 and the back body 3 with each other. This is the position of the folding lines 1a and 1a generated on the side of the holder. Similarly, the lower end 1b of the crotch region is the position of the folding line 1b generated in the crotch part 4 when the pad holder 1 is brought into a flat natural state by bringing the skin facing surfaces of the front body 2 and the back body 3 into contact with each other. It is.

In the front body first extension restraining portions 21 and 22, the end portions 21a and 22a on the body region b1 side may not reach the folding lines 1a and 1a, but reach the folding lines 1a and 1a. It is preferable. Moreover, as for the front body 1st expansion | extension suppression part 21 and 22, the edge parts 21b and 22b by the side of the crotch area b2 have entered into the area | region 41 between a pair of leg opening parts 6 and 6, as shown in FIG. Is preferable, and it is more preferable that the folding line 1b is reached.
The distance L4 (see FIG. 1) between the pair of leg openings 6 and 6 in the width direction of the pad holder is 3 to 3 from the viewpoint of improving the adhesion of the pad holder 1 and the absorbent pad 7 to the wearer's crotch. It is preferable that it is 15 cm, and it is more preferable that it is 6-12 cm. Moreover, it is preferable that the front body 1st expansion | extension suppression parts 21 and 22 do not cross | intersect mutually in the crotch area | region b2 of the front body.

  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 crotch region b2 on the front body side to the side portion of the body region b1, An angle α formed with a straight line (for example, the straight line L21) extending in the width direction of the pad holder is formed in an arc shape so as to gradually decrease as the side portion of the body region b1 is approached. With such a configuration, it is possible to prevent weight and distortion from being concentrated on one point on the line of the front body first extension suppressing portions 21 and 22, so that the front body first extension suppressing portions 21 and 22 can be worn by the wearer. It fits into the body shape without gaps and is more easily caught on the superior anterior iliac spines 8,8. Therefore, it is more excellent in a feeling of wearing and slip-off prevention.

  Further, as shown in FIG. 1, the front body 2 of the pad holder 1 has three front body second extension suppressing portions 23 to 25, respectively, in the width direction of the pad holder (corresponding to a direction along the waistline direction). It is extended and formed. These front body second extension suppressing portions suppress the extensibility of the pad holder 1 in the width direction. Moreover, the three front body 2nd expansion | extension suppression parts 23-25 are arrange | positioned intermittently in the vertical direction of a pad holder. Of these, two are arranged in the crotch region b2, and one is arranged in the trunk region b1. From the standpoint of retention of the absorbent pad, the length along the longitudinal direction of the pad holder of each front body second stretch suppression portion is shorter than the length in the same direction of the highly stretchable portion positioned in the vertical direction. Is preferred.

The length along the longitudinal direction of the pad holder of the front body second extension suppressing part may be changed from the outside in the width direction of the pad holder 1 toward the inside. From the viewpoint of pad retainability, the width may be increased from the outside in the width direction toward the inside.
The front body second extension restraining portion is formed to extend in the width direction of the pad holder. Here, “form to extend in the width direction” is limited to a form along the axial direction of the width direction. However, any shape may be used as long as it extends in the width direction. The shape is convex upward or downward in the vertical direction, the shape is extended in the vertical direction from one side in the width direction to the other side, or wavy. Or the like. Specific examples include a U shape, a V shape, a W shape, and an X shape. From the viewpoint of pad retainability and fitability to the wearer, it is preferably linear or convex downward. In addition, "the length along the vertical direction of the front body second expansion | extension suppression part" refers to the length along the vertical direction on the median line of the front body 2nd expansion | extension suppression part.
The three front body second extension suppressing portions 23 to 25 are respectively formed between the pair of front body first extension suppressing portions 21 and 22. More specifically, as for the front body 2nd expansion | extension suppression parts 23-25, all the both ends exist in the position of the front body 1st expansion | extension suppression parts 21 and 22.
Moreover, the front body 1st expansion | extension suppression part 21 and 22 is extended in the waist area | region side (upper side) from the position of the front body 2nd expansion | extension suppression part 23 nearest the waist area | region A.

  The front body first extension restraining portions 21 and 22 (the back body first and back body intermediate stretch restraining portions to be described later) have a maximum extension rate in the longitudinal direction of the pad holder. The part which is made smaller than the part located on at least one of the both sides sandwiching the first extension suppressing part, or the waist part of the front body or the back body when the specific load is applied in the longitudinal direction of the pad holder Includes a portion made smaller than at least one of the both sides sandwiching the front body first elongation suppressing portion, but the former is preferable from the viewpoint of detachability and wearing feeling.

The front body second extension suppressing portions 23 to 25 (the same applies to the rear body second extension suppressing portion described later) have a maximum extension rate in the width direction (also referred to as a lateral direction) of the pad holder, and the waist portion of the front body or the back body. The portion that is made smaller than the portion located on at least one of the both sides sandwiching the front body second extension restraining portion, or the stretch rate when a specific load is applied in the longitudinal direction of the pad holder is the front body or the back body It is a part made smaller than the part located in at least one of the both sides which pinch | interpose the front body 2nd expansion | extension suppression part in a waist part.
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 of the front body first elongation suppressing portions 21 and 22 is preferably less than 180%, more preferably 20 to 150%, and still more preferably 40 to 120%.
The maximum elongation rate of the front body second elongation suppressing portions 23 to 25 is preferably less than 200%, more preferably 50 to 180%, and still more preferably 70 to 160%.
Highly extensible parts other than the front body first and front body second elongation suppressing parts 21 to 25 in the waist part B of the front body 2, that is, parts having relatively higher extensibility than the elongation suppressing parts, for example, the front body first 1 The maximum elongation rate (Y direction) of the highly extensible portion present in at least one of the portions located on both sides of the stretch suppressing portion 21 (22) is determined by the ease of attaching and detaching the pad holder and the feeling of wearing. From the point of view, it is preferably 120% or more, more preferably 125% or more, and further preferably 180% or more, and the difference from the maximum elongation rate of the front body first elongation suppressing portion 21 (22). However, it is preferable that it is 30% or more, especially 50 to 150%. In addition, it is more preferable that the portions located on both sides of the front body first extension suppressing portion are within the above ranges.
In addition, for example, the maximum elongation ratio (X direction) of the highly extensible portion existing in at least one of the portions positioned above and below the second body stretching suppression portions 23 to 25 is easily attached / detached with the pad holder. 160% or more from the viewpoint of the property, wearing feeling, and retention of the absorbent pad, more preferably 180% or more, still more preferably 200% or more, and the elongation suppressing portions 23 to 25 The difference from the maximum elongation is preferably 20% or more, particularly preferably 30 to 130%. In addition, it is more preferable that the parts located on both sides of the front body second extension suppressing part are within the above-mentioned ranges.

  Moreover, the pad holder 1 is 35% or more of the total area (total area of the outer surface or inner surface) of the pad holder 1 in the natural state, more preferably 50% or more, and still more preferably 65% or more. It is preferable from the viewpoint of ease of attaching and detaching the pad holder and wearing feeling that the portion has a higher extensibility than the portion 21 (22), that is, a portion having a larger maximum elongation rate. The total area of the front body first extension restraining portions 21 and 22 is 5% or more and less than 30%, particularly 3% or more and less than 20%, and further 5% or more and less than 15% of the total area of the pad holder 1 in the natural state. Is preferable from the viewpoints of a feeling of wearing, a lifting property at the time of wearing operation, a stable holding property of the absorbent pad, and the like. 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%. In addition, about these numerical ranges, it is the same also about each area of the back body 1st expansion | extension suppression part and back body 2nd expansion | extension suppression part which are mentioned later.

The maximum extension rate of the front body first extension suppressing unit 21 (22) is measured by extending the extension suppressing unit 21 (22) in the longitudinal direction (Y direction) of the pad holder.
The maximum extension rate of the front body second extension suppressing units 23 to 25 is measured by extending the extension suppressing units 23 to 25 in the width direction (X direction) of the pad holder.
On the other hand, the maximum elongation ratio (Y direction) of the highly extensible portion other than the first body body first elongation suppressing portion 21 (22) is measured by extending the highly extensible portion in the longitudinal direction (Y direction) of the pad holder. To do.
The maximum elongation ratio (X direction) of the highly extensible portion other than the front body second elongation suppressing portions 23 to 25 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 unit 21 (22)]
From the pad holder to be measured, in the natural state, in a rectangular shape with dimensions of 100 mm in the vertical direction (Y direction) and 50 mm in the width direction (X direction), and in the center of the longitudinal direction (Y direction) of the measurement sample It cuts out so that the expansion | extension suppression part 21 (22) may be included over the range of at least 60 mm, and let this cut-out rectangular shape be a sample for a measurement. In addition, although the said sample adjustment method presupposes that the front body 1st expansion | extension suppression part 21 (22) has arrange | positioned continuously over the full range of 60 mm, the front body 1st expansion | extension suppression part 21 (22) Is included in this category even if it is divided at a part thereof and intermittently contains a highly extensible part.
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 extension suppressing portion 21 (22) 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 ratio (Y direction) of the highly extensible portion other than the front body first elongation suppressing portion 21 (22) is the same as described above. However, when the measurement sample is cut out, the front body first elongation suppression unit 21 (22) is not included in the measurement sample. However, the front body second extension suppressing portions 23 to 25 may be included in the measurement sample.

[Maximum elongation rate measurement method of the front body second elongation suppression unit 23 to 25]
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 (Y direction), and the center of the measurement sample in the longitudinal direction (corresponding to the X direction) In addition, 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. In addition, although the said sample preparation method presupposes that the front body 2nd expansion | extension suppression parts 23-25 are arrange | positioned continuously over the full range of 60 mm, the front body 2nd expansion | extension suppression parts 23-25 are Forms that are partly divided and contain highly extensible parts 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 extension suppressing portions 23 to 25 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 ratio (width direction) of the highly extensible portion other than the front body second elongation suppressing portions 23 to 25 is the same as described above. However, when the measurement sample is cut out, the elongation suppression units 23 to 25 are not included in the measurement sample. However, the front body first elongation suppressing unit 21 (22) may be included in the measurement sample.

In addition, the extension restraining part means that “the extension rate when a specific load is applied in the vertical direction of the pad holder is smaller than the peripheral part” means that the excrement is held by the pad in a normal wearing state. This means that the expansion rate is small when compared with the expansion rate at the time of 3N weighting. 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.
Although the width | variety in particular of the expansion | extension suppression part 21-25 is not restrict | limited, For example, the width | variety of the thing of the example of illustration is about 0.5-5 cm.

  According to the pad holder 1 of the present embodiment, the absorbent pad 7 is a plurality of the front body first and front body second extension restraining portions 21 to 25, particularly the plurality of front body second stretch restraining portions. While being able to make it adhere to a wearer's skin and the front body 1st expansion | extension suppression part 21 is extended from the crotch area | region b2 to the trunk | drum area | region b1, the extension to the vertical direction of the pad holder 1 is suppressed, When the waist region A is pulled up, the crotch regions b2 and d2 in which the absorbent pad 7 is disposed follow and are pulled upward. Thereby, the absorptive pad 7 can be made to fit a wearer's crotch part favorably.

Moreover, when the front body 2nd expansion | extension suppression parts 23-25 are spanned between the front body 1st expansion | extension suppression parts 21 and 22, the front body 2nd expansion | extension suppression parts 23-25 are like a hammock. Since the front body first extension suppressing portions 21 and 22 function as described above, the front body second extension suppressing portions 23 to 25 hang downward even when the weight of the absorbent pad 7 increases due to liquid absorption. Can be effectively suppressed. Thereby, the absorptive pad 7 can be satisfactorily held (held) in a state fitted to the wearer's crotch.
Furthermore, the shaking of the absorbent pad is absorbed at the intersection (intersection) of each of the front body second extension suppressing units 23 to 25 and the front body first extension suppressing units 21 and 22, The main body can be prevented from distorting due to the shaking of the absorbent pad (effect of beam).
These effects are more effective when the plurality of front body second extension suppressing portions 24 and 25 exist in the crotch region b2 of the front body as in the present embodiment.
The front body second extension suppressing portions 23 to 25 do not exist in the upper region of the trunk region b1 (the region on the side of the trunk region b1 from the longitudinal center of the trunk region b1 toward the waist opening 5). It is preferable. In the upper region of the torso region b1, the effect of preventing the displacement of the main body due to the displacement of the absorbent pad by the second stretch suppressing part of the front body and the shaking of the absorbent pad (effect of the beam) is small. There is a concern that the wearer may feel pressure, which is not preferable.

  It is preferable that the front body first and front body second elongation suppressing portions do not include elastic yarn such as polyurethane elastic fiber (spandex). When an elastic yarn having shrinkage is included in the stretch suppressing part, when the front body first and the front body second stretch suppressing part cross each other, the tissue density (knitting structure density in the case of a knitted fabric) increases at the crossing part. Curing of is likely to occur. When the elastic yarn is not included, such curing does not occur and irritation to the wearer's skin can be suppressed. Even if the elastic yarn is not included, the front body second extension suppressing portions 23 to 25 extend between the front body first extension suppressing portions 21 and 22 so that the absorbent pad is securely fitted to the crotch portion of the wearer. Can be made.

From the viewpoint of obtaining one or more of the effects described above more reliably, it is preferable that all the front body second extension suppression parts intersect the front body first extension suppression part. It is sufficient that at least one or more cross. The term “crossing” as used herein includes a state in which the first body body first stretch suppressing portion and the front body second stretch restraining portion intersect at least in part, and a distance of less than 10 mm also has a similar action. . However, in order to obtain a reliable effect, it is preferable that at least a part of the front body first extension suppressing portion and the front body second extension suppressing portion intersect each other.
The fact that the front body second extension suppressing portion extends between the front body first extension suppressing portions 21 and 22 is intermittent and spaced apart by a distance of less than 10 mm because it has a similar action as well as being continuous. Including. However, in order to obtain a reliable effect, it is preferable that the front body second extension suppressing unit is continuously arranged between the front body first extension suppressing units 21 and 22.

  Moreover, the position of the longitudinal direction of an absorptive pad can be easily match | combined by arrange | positioning the front body 2nd expansion | extension suppression parts 23-25 intermittently. Furthermore, by disposing at least one front body second extension suppressing portion 24 (25) in the crotch region b2 of the front body, the front body first extension suppressing portions 21 and 22 are suppressed from shifting in the width direction. Therefore, it is preferable because the fit of the crotch part is good, the absorbent pad can be easily attached, and the absorbent pad is difficult to sway during wearing. This effect is more easily exhibited when a plurality of front body second extension suppressing portions 24, 25 are present in the crotch region b2 of the front body.

From the viewpoint of obtaining one or more of the effects described above more reliably, the front body first extension restraining portions 21 and 22 are located on the waist region side (upper side) from the position of the front body second extension restraining portion 23 closest to the waist region A. ) Extends 3 cm or more in the longitudinal direction of the pad holder, and more preferably 5 to 10 cm.
In addition, the front body second extension suppressing portion 23 closest to the waist region A has a distance L23 from the folding line 1b to the center position of the extension suppressing unit 23, and a distance L2 from the lower end of the waist region A to the folding line 1b. It is preferable that it exists in the position which is in the range of 30 to 90%, particularly 45 to 75% of (see FIG. 1), and at least one other front body second extension suppressing part suppresses extension from the folding line 1b. It is preferable that the distance to the center position of the part 23 exists in the position which becomes in the range of 10-50% of the said L2, especially 20-40%. In terms of dimensions, the distance L23 can be, for example, 8 to 20 cm, and particularly preferably 13 to 18 cm.

Even if one or two or more of the front body second extension suppressing portions in the present invention cross the front body first extension suppressing portion in a cross shape and extend further outward in the holder width direction than the intersecting portions. good. For example, as shown in FIG. 6, the front body second extension suppressing portions 23 ′ to 25 ′ excluding the one 26 ′ that is closest to the folding line 1 b of the crotch region b 2 are the front body first extension suppressing portions 21. , 22 extends outward from the holder and reaches the folding line 1a. In this case, it is easy to obtain the effect associated with the suppression of the wobbling in the width direction of the front body first elongation suppressing portion in the crotch region b2 of the front body described above.
However, on the other hand, as in the present embodiment, when the front body second extension suppressing portions 23 to 25 are not extended outward in the holder width direction from the positions of the front body first extension suppressing portions 21 and 22, The tightening around the legs can be reduced, and this facilitates the insertion of the legs into the leg openings 6 and 6 and the withdrawal of the legs from the openings 6.
Moreover, although the front-and-rear end of an absorbent pad is easy to shift | deviate largely in the left-right direction, the length between front body 1st expansion | extension suppression parts 21 and 22 (length of the front body 2nd expansion | extension suppression part), so that it approaches the waist area | region A. Therefore, the lateral displacement of the front and rear ends of the absorbent pad can be effectively suppressed, and excessive tightening around the legs can be prevented.

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.

  As shown in FIG. 2, the pad holder 1 of the present embodiment is configured such that the upper front iliac spines 8 and 8 are covered by the front body 2 when worn. The upper anterior iliac spine is an anatomical term, and is a blunt protrusion (portion indicated by reference numeral 8 in FIG. 5) existing at the front end of the iliac crest. The superior anterior iliac spine 8 exists near the body surface, and a pair exists on the left and right sides of the wearer. In FIG. 2, the position of the navel is indicated by reference numeral 10.

As shown in FIG. 2, each of the pair of front body first extension restraining portions 21 and 22 in the pad holder 1 of the present embodiment has portions 21 c and 22 c of the upper anterior iliac spine 8 of the wearer when worn. It is formed so as to be positioned above.
When the front body first extension suppressing portions 21 and 22 are arranged in such a manner, the pad holder 1 is pulled down when the pad holder 1 is worn due to an increase in the weight of the absorbent pad 7 due to liquid absorption or the like. Even if force is applied, the front body first extension restraining portions 21 and 22 are caught by the upper anterior iliac spines 8 and 8, and the front body first extension restraining portions 21 and 22 in which the extension is restrained are stretchable. In order to suppress the downward movement of the crotch part 4 against the elongation of the highly extensible part made of a sheet, it is possible to more effectively prevent the absorbent pad 7 and the pad holder 1 from sliding down. it can.

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 order to effectively prevent the absorbent pad 7 and the pad holder 1 from slipping downward, and the pad holder 1 flexibly responds to changes in the abdominal circumference due to breathing or the like, the extension restraining portions 21 and 22 include at least the front body It is preferable not to cross each other in the body region b1.

  From the standpoint of obtaining the above-described effects more reliably, the front body first extension restraining portions 21 and 22 are located on the widthwise center portion side of the pad holder 1 from the crotch region b2 toward the side edges 1a and 1a of the trunk region b1. It is preferable to draw a curve that is convex. That is, it is preferable that the tangents of the respective points of the front body first extension suppressing portions 21 and 22 are directed toward the crotch side from the outer side in the width direction of the pad holder 1 toward the central portion side. However, the tangent line may be parallel to the width direction of the pad holder 1 in the vicinity of the side edges 1a and 1a.

  Further, as shown in FIG. 2, the pad holder 1 of the present embodiment has a portion that covers the upper anterior iliac spines 8, 8 in the front body 2, which is a higher extension portion than the extension suppressing portions 21 to 25. The upper anterior iliac spines 8 and 8 are easily caught near the boundary between the first extension suppressing portions 21 and 22 and the highly extensible portion. 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 above-described extension suppressing portions 21 to 25, so There is no need to place an elastic member along the ridge and press the pad holder against the ridge. It is preferable not to tighten the ridge portion with an elastic member from the viewpoints of reducing irritation to the skin and good wearing feeling, and particularly preferable for elderly people with weak skin. In the case where an elastic member is disposed at the heel portion, the elastic member contracts and tries to move to a stable place having a short circumference, and exerts an action of pulling the front body first extension suppressing portions 21 and 22 downward. For this reason, it is preferable not to arrange an elastic member along the vicinity of the ridge portion from the viewpoint of preventing slipping.

  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. Moreover, the expansion | extension suppression part (width direction expansion | extension suppression part) which suppresses the extensibility of the width direction is formed in the opening peripheral part of the leg opening parts 6 and 6 with a large movable amount and a large circumference difference between individuals. It is preferable that the width direction expansion suppressing portion is not formed within 3 cm from the opening peripheral edge of the leg openings 6 and 6. In addition, the longitudinal extension suppression part may exist in the opening peripheral edge part of the leg opening parts 6 and 6, and its vicinity.

In the pad holder 1 of this embodiment, as shown in FIGS. 3 and 4, the extension restraining portions 31, 32, 33, and 34 are also formed in the back body 3.
More specifically, in the rear body, a pair of rear body first extension restraining portions 31 and 32 extending from the crotch region d2 to both side edges 1a and 1a of the body region d1, and a waist from the crotch region d1 A pair of rear body intermediate extension suppressing portions 33 and 34 extending toward the region A are formed.
As shown in FIG. 3, the crotch region d2 is positioned below a straight line L31 that bisects the length (measured on the CL) between the waist region A and the lower end 1b of the crotch region in the back body 3. The body region d1 is a portion located below the waist region A and above the straight line L31.

Both side edges 1a, 1a of the body region d1 are the positions of the folding lines 1a, 1a, and are common to both side edges 1a, 1a of the body region b1 of the front body 2. The lower end 1b of the crotch region is the position of the folding line 1b and is common to the lower end 1b of the crotch region of the trunk region b1 of the front body 2.
The elongation suppressing portions 31, 32, 33, and 34 have a lower maximum elongation rate than the other highly extensible portions. The preferable extensibility of the expansion | extension suppression parts 31-34 is the same as that of the front body 1st expansion | extension suppression parts 21 and 22 by the front body 2 side mentioned above.

  As for the back body 1st expansion | extension suppression parts 31 and 32, it is preferable that the edge parts 31a and 32a by the side of the crotch area | region d2 have reached the said folding lines 1a and 1a, as shown in FIG. It is preferable that the end part 33a, 34a by the side of the trunk | drum area | region d1 exists in the trunk | drum area | region d1. However, the distance between the end portions 33a and 34a and the opening peripheral edge of the waist opening is preferably 3 cm or more, particularly 5 cm or more. When the end portions 33a and 34a reach the arrangement position of the waist elastic member 51, the longitudinal (Y direction) stretchability of the back side pad holder is lowered, and there is a concern about the back side slipping. .

  The end portions 31b, 32b, 33b, 34b on the crotch region d2 side of the back body first and back body intermediate extension suppressing portions 31 to 34 are regions 41 between the pair of leg openings 6 and 6 in the crotch region d2, respectively. It is preferable that each of the folds has reached the folding line 1b.

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 rear body first extension restraining parts 31 and 32 of the back body 3 are provided on the crotch part and the side part of the wearer. It is connected at the site | part arrange | positioned, and is continuing cyclic | annular as a whole. Thereby, since the position where the expansion | extension suppression part which continued cyclically | annularly is fixed by the pubic bone coupling | bond part and an upper anterior iliac spine, slipping down is further suppressed.
The pubic joint portion refers to a portion where the pubic bone located on the left and right sides below the pelvis is joined at the crotch center.

  The distance W3 (see FIG. 3) between the back body first extension suppressing part and the back body intermediate extension suppressing part on the same left and right sides of the pad holder 1, that is, the back body first extension suppressing part 31 and the back body intermediate extension suppressing part. The distance between the first body 33 and the back body first extension restraining portion 32 and the back body intermediate stretch restraining portion 34 gradually increase from the bottom to the top of the pad holder 1. Thereby, while suppressing the center part (for example, part which has an absorptive core inside) of the absorptive pad 7 by the back body 1st expansion | extension suppression part 31, both sides of the absorptive pad 7 are controlled by the back body middle expansion | extension suppression part 34. A part (for example, a side flap part etc. extended from the both-sides edge of an absorptive core) can be suppressed, and a leak-proof property improves. Moreover, since the space | interval W3 of an expansion | extension suppression part opens as it progresses to a waist opening part side, even the bowl-shaped pad opened front and back in the shape of a fan can be made to fit skin firmly.

  As the stretchable sheet forming the pad holder 1 of the present embodiment, a knitted fabric, a stretchable nonwoven fabric, or the like can be used, but a knitted fabric is preferable, and the yarn itself has stretchability and expresses stretchability. It is preferable to use a knitted fabric formed by an easy knitting method. In the pad holder 1 of the present embodiment, the portions other than the waist opening and the opening peripheral edge of the pair of leg openings are formed from a stretchy knitted fabric manufactured by a circular knitting machine or the like, and an extension suppressing portion In the portions 21 to 25 and 31 to 34, the maximum elongation rate is lowered by making the mesh of the knitted fabric denser than the other portions. Examples of other forming methods of the extension suppressing portions 21 to 25 and 31 to 34 include a method in which a belt-like sheet having inferior extensibility is joined to a sheet having excellent stretchability by stitching or fusion. Moreover, the method of using the knitted fabric formed with the thread | yarn whose extensibility is lower than the high extensibility part for the expansion | extension suppression parts 21-25 is mentioned. For example, a method of using a knitted fabric made of rayon yarn and cotton yarn for the stretch suppressing portion and the high stretch portion, and increasing the blending rate of the stretch restraining portion as compared to the high stretch portion can be mentioned.

As mentioned above, although this invention was demonstrated based on the preferable embodiment, this invention is not restrict | limited to embodiment.
For example, the front body first extension suppressing portions 21 and 22 have a linear portion and an arc-shaped portion instead of an arc-shaped portion over the entire length, or two or three connected at an angle. What consists of the above linear part etc. can also be provided.

Further, in the above-described pad holder 1, the number of the front body second elongation suppressing portion is three, but it may be two or four (for example, four to eight), particularly 2 to seven. From the viewpoint of adhesion and ease of attachment / detachment, 2 to 5 are more preferable. For example, any one of the three front body second extension suppressing units 23 to 25 in the pad holder 1 is omitted, or two or more front body second parts between the front body second extension suppressing units 23 and 25 are omitted. An extension suppressing part can also be arranged.
Further, the front body first extension restraining portions 21 and 22 of the front body 2 of the pad holder 1 may not reach the folding lines 1a and 1a and / or the folding line 1b. Either one or both of the 1 extension suppressing units 31 and 32 and the back body intermediate extension suppressing units 33 and 34 may be omitted.
Moreover, it is not necessary for each of the front body first extension suppressing part and the front body second extension suppressing part to extend continuously, and the extension suppressing part is divided at a part thereof to include a part having a high extension. In this case, for example, the extension suppressing part and the highly extensible part may be arranged alternately.

  Further, in the back body, one or more back body second extension suppressing portions extending in the pad holder width direction may be provided between the pair of back body first extension suppressing portions 31 and 32. As shown in FIG. 7, when providing a plurality of back body second expansion | extension suppression parts, it arrange | positions intermittently in the vertical direction of a pad holder. The back body second extension suppressing portions 35 to 38 have a lower maximum extension rate in the width direction (X direction) than other parts (highly extensible parts). The preferable extensibility of the back body second extension suppressing part 35 to 38 is the same as that of the front body second extension suppressing part described above. Further, as shown in the drawing, the rear body second extension restraining portions 35 to 37 except for the one existing closest to the folding line 1b in the crotch region are more outward in the holder width direction than the rear body first extension restraining portions 31 and 32. In this case, in the case of the folding lines 1a and 1a of the pad holder, the rear body second extension suppressing portions 35 to 37 that extend are shown in FIG. It is preferable to be provided so as to be connected to the portions 23 ′ to 26 ′. And the position of the back body 2nd expansion | extension suppression part 35 nearest the waist opening part 5 is the crotch part 4 rather than the position of edge part 31a, 32a by the side of the trunk | drum area | region b1 of the back body 1st expansion | extension suppression parts 31 and 32. It is preferable that the rear body second elongation suppressing portion 35 and the front body second elongation suppressing portion 23 ′ are connected to each other, and the rear body second elongation suppressing portion 35 and the front body second portion are connected. The upper anterior iliac spines 8 and 8 of the wearer are covered in a region surrounded by the extension suppressing portion 23 ′, the rear body first extension suppressing portions 31 and 32, and the front body first extension suppressing portions 21 and 22. It is preferable that it is made.

Moreover, the pad holder 1 may make the total light transmittance of the central region in the width direction higher than the total light transmittance of the side region in the width direction. For example, the total light transmittance between the front body first stretch suppression units 21 and 22 in the waist part B of the front body 2 is set to be wider than the first body body first stretch suppression units 21 and 22 in the waist part B of the front body 2. It may be higher than outside. Further, the total light transmittance between the back body first stretch suppression units 31, 32 in the back body 3 or between the back body intermediate stretch suppression units 33, 34 is set to be the third or back body intermediate stretch suppression unit 21 in the front body 3, Each of 22 may be higher than the outside in the width direction.
The total light transmittance is measured using, for example, HR-100 manufactured by Murakami Color Research Laboratory in accordance with JIS K7150 (Measurement Method A).
By doing in this way, the pad holder 1 determines whether or not the absorbent pad 7 is disposed at an appropriate position by a caregiver or the like through the high light passage rate portion on the outer surface (non-skin facing surface) of the pad holder 1. From the side). In addition, when an indicator processing unit is provided on the absorbent pad 7 and the care recipient needs to urinate, the indicator processing unit of the absorbent pad 7 passes through the high light transmission rate unit to the outer surface of the pad holder 1 (non-skin facing). It can be recognized by the caregiver from the front side).

The indicator processing unit is preferably arranged along the longitudinal direction on the back surface side of the absorbent pad 7 from the viewpoint of urination sensing reliability and visibility.
From the viewpoint of fixing the absorbent pad 7, it is preferable that the absorbent pad 7 has a fixing means for fixing to the pad holder 1 on the back sheet side surface. From the viewpoint of displacement prevention, a mechanical fastener (male material) is preferable. The mechanical fastener (male material) is preferably disposed in the vicinity of the front and rear ends of the absorbent pad 7 so as not to hinder the visibility of the indicator processing portion.

  Moreover, the pad holder 1 described above may be a high leg type instead of the boxer brief type. However, in the present invention, from the viewpoint of preventing a problem that the vicinity of the product crotch is caught on the thigh and cannot be sufficiently pulled up during the pulling, the opening peripheral edge of the pair of leg openings 6 and 6 is more than the folding line 1b. The boxer brief type pad holder located below exhibits a particularly excellent effect.
