The menstrual shorts disclosed in Patent Literature 1 have an upper band that extends upward from the shorts body and is arranged around the wearer's torso in a belly band shape, thereby warming the entire abdomen of the wearer and relieving menstrual pain. can be mitigated.

However, since the upper band is made of wide rubber, it is relatively difficult to stretch in the waist direction (lateral direction). It can be said that it is difficult to replace the napkin by inserting both hands between the body and the upper band due to the tightening force of the upper band. Therefore, the wearer has to bend the upper band by pulling it by hand, and then perform the replacement work, which is troublesome. Also, in the shorts body, it can be said that replacing the sanitary napkin becomes easier if the upper part located closer to the upper band is more likely to stretch in the waistline direction than the lower part where the crotch part is located.

The present invention is an improvement of conventional sanitary shorts, which can alleviate menstrual pain by warming the entire abdomen of the wearer and facilitate replacement of the sanitary napkin. The challenge is to provide

In order to solve the above problems, a front body having a longitudinal direction and a lateral direction, a back body, a crotch region positioned between the front and back bodies, an upper edge of the front body and an upper edge of the back body and a pair of leg openings.

The embodiments below relate to the sanitary shorts 10 shown in FIGS. 1-8 and include optional and preferred configurations as well as essential features of the invention. For convenience of explanation, the warm sheets 81 and 82 are shaded in light black, and the waterproof cloth 70 is shaded in each figure.

1 to 6, a sanitary shorts 10 shown as an example of the sanitary shorts of the present invention has a longitudinal direction Y, a lateral direction X, and a front-rear direction Z when worn, and has a waist opening 3 and It has a pair of leg openings 4, a front body 11, a back body 12, and a crotch region 13 positioned between the front and back bodies 11,12. The crotch region 13 is located between a pair of transverse suture lines 45, 46 for convenience of explanation. The sanitary shorts 10 further have a longitudinal centerline P that bisects the length in the longitudinal direction X, and a transverse centerline Q that bisects the length in the lateral direction X. As shown in FIG.

The sanitary shorts 10 include a shorts main body 20 covering from the lower abdomen to the buttocks of the wearer when worn, and an upper band 30 extending upward from the shorts main body 20 and arranged around the waist of the wearer in a belly band shape. including. The shorts main body 20 and the upper band 30 are connected to each other at a boundary sewing line (boundary portion) 41 extending in the lateral direction X. As shown in FIG. Since the sanitary shorts 10 have the upper band 30, the shorts main body 20 and the entire abdomen of the wearer can be covered and warmed, thereby relieving menstrual pain.

For convenience of explanation, the shorts body 20 is divided into a lower portion 21 where the crotch region 13 is located and an upper portion 22 located between the lower portion 21 and the upper belt 30 . A circularly extending boundary elastic body 63 is arranged on a boundary sewing line 41 where the upper band 30 and the upper portion 22 of the shorts body 20 are overlapped and sewn together.

The front body 11 consists of the front part 30A of the upper belt 30 and the front part 22A of the upper part 22 of the shorts body 20, and the back body 12 consists of the rear part 30B of the upper belt 30 and the upper part 22 of the shorts body 20. are formed from the front part 22A of the . Both side edges 11c and 11d of the front body 11 are formed from both side edges of the front portion 30A of the upper band 30 and both side edges of the front portion 22A of the upper portion 22 of the shorts body 20. Both side edges 12 c and 12 d are formed from both side edges of the rear portion 30</b>B of the upper band 30 and both side edges of the rear portion 22</b>B of the upper portion 22 of the shorts body 20 .

Both side edges 11c and 11d of the front body 11 and both side edges 11c and 11d of the back body 12 are joined to each other by a longitudinal sewing line (sewing line) 42 extending in the longitudinal direction Y, thereby forming a pair with the waist opening 3. and leg openings 4 are defined. Both side edges 11c and 11d of the front body 11 and both side edges 12c and 12d of the back body 12 are joined via a vertical sewing line 42 with their outer surfaces in contact with each other. 42 is located on the inner surface side of the shorts main body 20 and the upper band 30 .

The shorts main body 20 has a body fabric 50 that forms the outer shape of the shorts main body 20 . The body fabric 50 has a front waist fabric 51 forming the outer surface on the front body 11 side, a rear waist fabric 52 forming the outer surface on the back body 12 side, and a crotch fabric 53 forming the outer surface of the crotch region 13 . The crotch fabric 53 has a first portion located on the front body 11 side and a second portion located on the back body 12 side, and the first and second portions are joined to each other via a cross sewing line 43. .

The upper band 30 has a band material (fabric) 31 composed of a material forming the front portion 30A and a material forming the rear portion 30B. In this embodiment, the upper band 30 is formed by folding a sheet of band material 31 at the edge of the waist opening 3 in the front portion 30A and the rear portion 30B. The front and rear portions 30A and 30B of the upper band 30 are formed by an inner surface portion positioned on the inner surface side and an outer surface portion positioned on the outer surface side of the band material 31, and a space is formed inside them. As a result, the air warmed to the body temperature of the wearer stays in the internal space, and the waist of the wearer can be warmed.

The body fabric 50 and the belt body fabric 31 are formed of a stretchable fabric (two-way stretch fabric) that can be stretched in the longitudinal direction Y and the lateral direction X by a knitting structure, and cotton yarn is mainly used as the material. A blend of cotton yarn and elastic yarn such as polyurethane elastic yarn is preferably used. In the present embodiment, organic cotton fibers can be preferably used as the cotton yarn.

Since the body fabric 50 and the band fabric 31 contain organic cotton fibers, the feeling of touch is improved, and the wearer can be given a sense of security due to the use of naturally-derived materials. The body fabric 50 and the belt body fabric 31 have different contents of elastic yarns, and therefore, as will be described later, the elastic force and the ease of stretching in the direction around the waist (lateral direction X) are different.

It is preferable that the content of organic cotton contained in body fabric 50 and band fabric 31 is 90% or more. Since the content of organic cotton is 90% or more, the sanitary shorts 10 as a whole are gentler on the skin than when fabrics made only of synthetic fibers or fabrics containing organic cotton with a low content are used. , it can be said that it is difficult to cause a rash.

The sanitary shorts 10 further have an annular waist elastic region 61 defining the waist opening 3 and leg elastic regions 62 defining the leg openings 4 . The opening edge of the waist opening 3 and the opening edge of the leg opening 4 are formed by the waist elastic region 61 and the leg elastic region 62, respectively, so that each opening edge fits the wearer's body.

In the sanitary shorts 10, the upper band 30 is connected to the shorts main body 20, so that the front and rear bodies 11 and 12 have relatively large longitudinal dimensions, and the waist opening 3 and the leg opening 4 are dull. When there is a risk that the sanitary shorts 10 may be separated from the body, the entire sanitary shorts 10 can be fitted to the body by placing the boundary elastic bodies 63 between them.

The waist elastic region 61 has a waist elastic body 64 arranged inside a folded portion formed by folding the band material in two so as to be contractible in a stretched state. The leg elastic region 62 is formed from a leg elastic 65 annularly extending along the leg opening 4 . The leg elastics 65 are attached to the inner surface of the body fabric 50 so as to be contractible in a stretched state.

The boundary elastic bodies 63, the waist elastic bodies 64, and the leg elastic bodies 65 are made of thread-like, tape-like, or ribbon-like elastic materials such as rubber, urethane, and elastic fiber nonwoven fabric.

2 and 5, the shorts main body 20 has a waterproof cloth 70 extending from the crotch region 13 toward the back body 12 side. The waterproof cloth 70 is joined to the inner surface of the body cloth 50 via a suture line. The waterproof cloth 70 extends to a boundary sewing line (boundary portion) 41 between the upper band 30 and the rear portion 22B of the upper portion 22 in the back body 12, and gradually narrows from the crotch region 13 toward the rear. It has a shape The waterproof cloth 70 has a wide portion 71 located in the crotch region 13 and a narrow portion 72 extending rearward from the wide portion 71 . By arranging the waterproof cloth 70 on the side of the crotch region 13 and the back body 12 of the shorts main body 20, leakage of body fluid spreading from the crotch region 13 and the back side of the wearer can be suppressed, especially when sleeping. can be done.

A longitudinal elastic body 75 extending from the crotch region 13 to the back body 12 along the longitudinal center line P is arranged on the inner surface side of the shorts main body 20 . The longitudinal elastic body 75 is interposed between the body cloth 50 and the waterproof cloth 70 . The longitudinal elastic body 75 is formed of the same elastic material as the waist elastic body 64 and the like, and one end 75A is fixed to the rear waist fabric 52 via the boundary sewing line 41, and the other end 75B is sewn across. By being fixed to the crotch fabric 53 via the attachment line 43, it is attached in the longitudinal direction Y so that it can be contracted in a stretched state.

One end 75A of longitudinal elastic body 75 is located at boundary sewing line 41 and connected to boundary elastic body 63, thereby preventing shorts main body 20 from slipping down when worn. In addition, since the abdomen of the wearer has a more rounded shape than the back, the longitudinal elastic body 75 is not arranged on the front body 11, which is likely to slip down during wearing. The contractile force of the front body 11 can prevent the front body 11 from sliding downward.

The longitudinal elastic body 75 continuously extends in the vertical direction Y in a strip shape, but may extend intermittently. In addition, the longitudinal elastic body 75 may extend continuously from the cross stitch line 45 to the cross stitch line 46 so as to cross the crotch region 13 . The longitudinal elastic body 75 is located on the outer surface side of the waterproof cloth 70 and the first and second warming sheets (heat sensitive sheets) 81 and 82 to be described later. 2 The warm sheets 81 and 82 can be pressed against the body. In particular, by positioning the first and second warm sheets 81 and 82 on the skin surface side of the longitudinal elastic body 75, the first and second warm sheets 81 and 82 come into contact with the skin and reliably warm the body. be able to.

Referring to FIG. 5, the crotch region 13 is provided with a patch cloth 77 fixed to the inner surface of the crotch fabric. The patch cloth 77 has front and rear ends extending in the horizontal direction X and both side edges extending in the vertical direction Y between the front and rear ends. Front and rear end portions of the patch cloth 77 are fixed to the crotch cloth 53 via a pair of transverse stitching lines 45 and 46 . Further, both side edges of the patch cloth 77 are not fixed to the crotch cloth, and portions other than the front and rear ends are not fixed to the crotch cloth 53 and are in a free (non-fixed) state. The patch cloth 77 is composed of two sheets located on the inner and outer surface sides, and the outer surface side (non-skin facing side) is made of synthetic fibers such as polyethylene fiber, polyester fiber and acrylic fiber, and is waterproofed. It is preferable to use a knitted fabric.

Although not shown, a sanitary napkin can be attached to the patch cloth 77 when wearing the sanitary shorts 10 . Specifically, with the non-skin-facing surface of the sanitary napkin applied to the patch cloth 77, the wings are folded and inserted between the waterproof cloth and the patch cloth 77, and the skin-facing side of the wing is folded. The sanitary napkin can be stably fixed to the sanitary shorts 10 by attaching it to the non-skin-facing surface of the patch cloth 77 via the adhesive portion located at . Since the padding cloth 77 is free except for its front and rear ends, it is suspended in the crotch region 13, and the sanitary napkin can be moved so as to follow the wearer's body movements. Blood leakage can be effectively prevented.

2 to 4, on the inner surface of the intermediate region of the front body 11, there is a first warm feeling extending in the lateral direction X between the vertical sewing lines 42 where the both side edges of the front and back bodies 11 and 12 are joined to each other. A sheet (warm sheet) 81 is arranged. The first warm sheet 81 has an outer peripheral edge consisting of upper and lower edges extending in the horizontal direction X and both side edges extending in the vertical direction Y between the upper and lower edges. The first warm sheet 81 is fixed to the front waist fabric 51 only at the outer peripheral edge 81a.

A second warming sheet (warming sheet) 82 extending in the horizontal direction X is arranged on the inner surface of the intermediate region of the back body 12 between the vertical sewing lines 42 where the side edges of the front and back bodies 11 and 12 are joined to each other. It is The second warm sheet 82 has an outer peripheral edge consisting of upper and lower edges extending in the horizontal direction X and both side edges extending in the vertical direction Y between the upper and lower edges. The second warm sheet 82 is fixed to the rear waist fabric 52 and the waterproof fabric 70 only at the outer peripheral edge 82a.

The first and second warm sheets 81 and 82 are made of a stretchable fabric (two-way stretch fabric) that is stretchable in the vertical direction Y and the horizontal direction X by a knitting structure. A warm material that can warm is used. Examples of warm-sensing materials used as fiber materials include fibers having a far-infrared radiation effect in which powdered ceramic is kneaded, heating powders such as heat, and oxidizable metals such as aluminum, zinc, manganese, and magnesium. and fibers having heat insulating and heat absorbing and heat absorbing effects such as wool, glass fiber, wood pulp fiber, etc. can be used. When using a fiber into which an acidizable metal that produces an exothermic effect is kneaded, activated carbon, carbon black, graphite, zeolite, etc., should be kneaded into the fiber together as an oxygen retaining/supplying agent to promote the exothermic reaction. is preferred.

In this embodiment, the thermal materials of the first and second thermal sheets 81 and 82 are alumina-based ceramics, zirconium-based ceramics, or the like, which can efficiently radiate far-infrared rays even at a low temperature of 20 to 40°C. It uses far-infrared fibers in which high-purity ultrafine ceramic particles are kneaded into each fiber. In addition to far-infrared fibers, it is preferable to use heat-storage fibers, which can be said to be a composite structural material in which a plurality of trace metal elements such as silicon, aluminum, and magnesium are combined with an organic plant carbonization material such as activated carbon.

The first and second warming sheets 81 and 82 have a far-infrared heat retaining function, in which the far-infrared fibers absorb far-infrared rays emitted from the wearer's body and radiate the far-infrared rays to the wearer's body, thereby further warming the body. In addition, the heat storage fiber efficiently absorbs the far infrared rays emitted from the body and reaches the far infrared rays, thereby providing a heat storage and heat retention function that allows more far infrared rays to be radiated. Therefore, compared to conventional warming sheets using only far-infrared fibers and conventional warming sheets using only fibers that produce heat insulation and moisture absorption and heat generation, heat retention is superior, and the body can be warmed to the inside. It can be said. In addition, secondary effects such as a deodorizing effect and a dehumidifying effect can also occur due to the presence of the porous heat accumulating fibers.

When the warming sheets 81 and 82 having such a heat retaining effect are arranged on the entire inner surface of the sanitary shorts 10, or when far-infrared fibers are used for the body fabric 50 itself, the warming sheets 81 and 82 The ventilation is low and the body is warmed over a wide area, which promotes sweating and may cause the inside of the sanitary shorts 10 to become stuffy. In particular, in the sanitary shorts 10 according to the present embodiment, when the warming sheets 81 and 82 are arranged in the crotch region 13 where the waist elastic region 61 and the leg elastic region 62 are located, the inside becomes stuffy and the elastic region Due to the stretching action of the rubber, rubber marks are likely to be left on the skin, and the skin may become irritated and cause skin troubles.

In this embodiment, the first and second warming sheets 81 and 82 are arranged on the upper portion 22 of the shorts main body 20 in the front and rear bodies 11 and 12, respectively. When the first and second warming sheets 81 and 82 are arranged only on the upper portion 22 and not arranged on the upper band 30 and the lower portion 21, the entire inner surface of the sanitary shorts 10 is warmed. It is possible to suppress stuffiness inside, rubber marks in the waist elastic region 61 and the leg elastic region 62, and rashes on the skin.

Referring to FIG. 7(a), when the sanitary shorts 10 are worn, the first warming sheet 81 is located locally on the front body 11 so as to face the uterus of the wearer's abdomen. It can relieve menstrual cramps by warming a person's uterus with the far-infrared effect. In addition, the second warming sheet 82 is disposed in the back body 12 at a position that locally faces the vicinity of the sacrum of the back of the wearer, and warms the vicinity of the sacrum of the wearer by the far-infrared effect to relieve lumbago due to menstruation. can be mitigated.

The first warming sheet 81 is arranged only on the rear part 22A of the upper part 22 of the front body 11, and the second warming sheet is arranged only on the rear part 22B of the upper part 22 of the back body 12. As a result, both side edges of the first warming sheet 81 and both side edges of the second warming sheet 82 are joined together with the body cloth 50 via the longitudinal sewing line 42 so as to at least partially overlap each other. ing. In this way, by connecting both side edges of the first warming sheet 81 and both side edges of the second warming sheet 82, an annular warm zone extending in the direction around the waist is formed. Alternatively, compared to the case where only the back is warmed, a part of the wearer's abdomen and back including the uterus and the vicinity of the sacrum can be annularly warmed to alleviate menstrual cramps more effectively.

However, both or at least one of the first and second warming sheets 81 and 82 may be arranged on the inner surface of the sanitary shorts 10 as long as the desired effect of alleviating menstrual pain is produced. Only the warming sheet 82 may be arranged on the inner surface of the back body 12 and the first warming sheet 81 may not be arranged on the inner surface of the front body 11 . In particular, since women often suffer from lower back pain rather than abdominal pain during menstruation, when the warming sheets 81 and 82 are arranged only on one of the front and back bodies 11 and 12, they can be arranged only on the back body 12.例文帳に追加preferable.

As described above, the first and second warming sheets 81 and 82 are fixed to the body cloth 50 and the waterproof cloth 70 only at the outer peripheral edges 81a and 82a, and the area surrounded by the outer peripheral edges 81a and 82a , inner spaces S1 and S2 separated from the body cloth 50 are defined. By forming the internal spaces S1 and S2 between the first and second warming sheets 81 and 82 and the body fabric 50 and the waterproof cloth 70, the air warmed by the far-infrared effect enters the internal spaces S1 and S2. Stay. Since the high-temperature air stays in the inner space and spreads in the lateral direction X, together with the far-infrared radiation effect of the first and second warming sheets 81 and 82, the vicinity of the wearer's uterus and sacrum is heated. Warming at a high temperature over a wide area and for a longer time can relieve menstrual cramps more effectively.

Referring to FIG. 6(a), the strip fabric 31 forming the upper strip 30 is formed by rib-weaving constituent yarns, and is arranged at intervals in the horizontal direction X, and It has a plurality of ribs 33 extending in the vertical direction.

The sanitary shorts 10 are composed of a shorts main body 20 and an upper band 30 and cover the wearer's lower half of the body in a relatively wide range, so that the inside tends to get stuffy, but the band material forming the upper band 30. By having a plurality of ribs 33 in 31, internal air is released from the waist opening 3 through the recesses 34 formed between the ribs 33 and external air is easily taken in, It is possible to prevent the inside of the sanitary shorts 10 from becoming stuffy and the skin from becoming irritated.

In addition, since the upper band 30 has a plurality of ribs 33, the contact area with the skin is reduced. The wearing operation can be performed smoothly without the 30 being in close contact with the body and being difficult to pull up.

Referring to FIG. 6( b ), at the boundary sewing line 41 , the band material 31 forming the upper band 30 is the skin of the body material (rear waist material 52 ) 50 forming the upper portion 22 of the shorts body 20 . Located on the opposite side. When the upper band 30 is located on the non-skin-facing side of the upper portion 22 at the boundary sewn line 41 , body fluids that have traveled from the crotch region 13 to the front and rear bodies 11 and 12 are and there is a risk of leaking to the outside from the gap between the upper part 22 and the upper belt 30, but by positioning the upper belt 30 on the skin facing side of the upper part 22, such a situation can be avoided. can.

Referring to FIGS. 7(a) and 7(b), when worn, the sanitary shorts 10 include an upper band 30 covering the waist of the wearer, and the shorts main body 20 extending from the sacrum to the lower abdomen. By having the first warm sheet 81 and the second warm sheet 82 facing each other, the wearer's entire abdomen and back can be effectively warmed to relieve menstrual pain. .

On the other hand, the sanitary shorts 10 have the upper band 30 extending upward from the shorts main body 20, and the longitudinal dimension Y of both side edges of the front and back bodies 11, 12 is relatively large. When the sanitary napkin attached to the patch cloth 77 of 13 is replaced with a new one after use, if the upper band 30 is relatively difficult to stretch, it is difficult to widen the waist opening 3, and the body and the sanitary shorts will not fit together. It is not possible to easily replace by inserting a hand between them.

In this embodiment, the upper band 30 is more likely to stretch in the lateral direction X (in the waistline direction) than the upper portion 22 of the shorts body 20, and the upper portion 22 is more likely to stretch in the lateral direction X (in the waistline direction) than the lower portion 21. f) It is easy to stretch. As a result, the upper band 30 has elasticity to the extent that it does not slide down from the proper position of the body when worn, and is easily stretchable in the lateral direction when the sanitary napkin is replaced, widening the waist opening 3 greatly. Exchange work can be done in this state.

In addition, since the upper portion 22 is more easily stretched in the lateral direction X than the lower portion 21, the upper portion 22 can be expanded together with the upper belt 30, while the lower portion 21 is relatively difficult to stretch. Therefore, even if the sanitary napkin is expanded in the lateral direction X together with the upper part 22 and its shape collapses, the sanitary napkin cannot be visually recognized even if it is seen through the waist opening 3, and the sanitary napkin itself is not twisted. Able to remove and install sanitary napkins. The stretchability in the lateral direction X of the shorts main body 20 and the upper strip 30 can be confirmed by the tensile strength in the lateral direction X measured by the measuring method described below.

In this way, since the sanitary shorts 10 become more difficult to stretch in the lateral direction from the top to the bottom, the provision of the upper band 30 gives the wearer the image of being difficult to put on and take off in the toilet or the like. However, since the upper band 30 is easily stretched in the lateral direction X, such concerns can be eliminated, and the sanitary napkin fits the body by being firmly held by the lower part 21.例文帳に追加Therefore, it is possible to give a sense of security that body fluid does not leak sideways even during sleep at night.

The length L1 in the vertical direction Y of the upper band 30 is 1.0 to 1.5 times as large as the length L2 in the vertical direction Y of the upper portion 22 of the shorts body 20 . For example, as shown in FIG. 8, the lengths L1 and L2 are 2 so that the front inner surface and the rear inner surface of the sanitary shorts 10 are in contact with each other via a transverse center line Q that crosses the crotch region 13. It can be measured with a measuring tool such as a ruler in the folded state. If the vertical dimension L1 of the upper band 30 is relatively too large, the body can be covered and warmed over a wide area, while the length from the waist opening 3 to the crotch region 13 is limited when replacing the sanitary napkin. The longer the distance, the more difficult the replacement work becomes. In this embodiment, since the length dimension L1 and the length dimension L2 have such a correlation, the upper belt 30 can warm the abdomen, and the upper belt 30 is relatively too long, It does not make it difficult to replace the sanitary napkin.

4 and 7(b), the narrow portion 72 of the waterproof cloth 70 intersects with the second warming sheet 82, and the waterproof cloth 70 overlaps with the second warming sheet 82 at the overlapping portion where it overlaps the most. It can be said that it has a narrow shape. In this way, by making the area of the portion of the waterproof cloth 70 that overlaps the second warming sheet 82 relatively small, the waterproof cloth 70 with low air permeability and the second warming sheet 82 overlap each other. It is possible to suppress the generation of stuffiness in the shorts 10 for wearing.

Although not shown, it is preferable that the upper band 30 and the shorts body 20 have different colors. In such a case, before wearing, the wearer is made to visually recognize that the sanitary shorts 10 are provided with the upper band 30 extending upward from the shorts body 20, and the entire abdomen is warmed to relieve menstrual pain. You can let us know that there is an effect to be done. Even if the belt material 31 and the body material 50 are formed from threads of the same color, it is possible to form the belt material 31 by rib weaving and the body material 50 by plain weaving, that is, by using different knitted fabrics. It can be said that the color tone looks different and the above effects can be achieved. Also, the threads of the belt body fabric 31 and the threads of the body fabric 50 may be colored in different colors.

<Method for measuring tensile strength>
Referring to FIG. 8, the tensile strength (hardness to stretch) in the lateral direction X in each region of the sanitary shorts 10 is measured using a digital force gauge 100 (manufactured by Nidec-Shimpo Corporation: SHIMPO FGP-2) as follows. measured by the method. Although FIG. 8 shows how the upper band 30 was measured, similar measurements were also performed for the upper portion 22 and the lower portion 21 in sequence.

The sanitary shorts 10 are laid flat on the measuring table 110, and the sanitary shorts 10 are folded in two so that the inner surface on the front side and the inner surface on the rear side are in contact with each other via the transverse center line Q that crosses the crotch region 13. bottom. Next, each area to be measured (upper belt 30 consisting of front part 30A and rear part 30B, upper part 22 of shorts main body 20 consisting of front part 22A and rear part 22B, and front part 21A The side edges of the lower portion 21) consisting of the rear portion 21B and the rear portion 21B are sandwiched between the clip portions 121 of the double clip 120. As shown in FIG. On the inner surface of the clip portion 121 of the double clip 120, an anti-slip tape (manufactured by 3M, "Safety-walk type SB yellow") 130 cut to match the width dimension (30 mm width) of the clip portion 121 was attached.

Next, a hook positioned at the tip of the digital force gauge 100 was hooked on the lever portion 122 of the double clip 120, and the state in which a tensile force of about 0.3 N was applied was defined as the start position (0 mm). While holding the side edge of the sanitary shorts 10 opposite to the side edge to which the double clip 120 is attached with one hand, the measurer separates the digital force gauge 100 from the sanitary shorts with the other hand. Measured values (N) were read at positions separated by 20 mm and 50 mm from the starting position. In addition, the separation dimension was measured with a ruler arranged on the mounting table. The measurement was performed four times (N=4), and the average value was taken as the tensile strength of each region. Table 1 below shows the measured results.

As shown in Table 1, the measurement results showed that the tensile strength in the lateral direction X was 2.4 N and 5.1 N when the distance between the upper strips 30 was 20 mm and 50 mm, respectively. The tensile strengths in the lateral direction X with the distances of 20 mm and 50 mm of the upper part 22 were 3.1 N and 6.2 N, respectively. Therefore, it can be said that the tensile strength in the lateral direction X of the shorts body 20 is higher than that of the upper band 30 (difficult to expand in the lateral direction X). In addition, the tensile strength in the lateral direction X at the separation dimension of 20 mm of the lower part 21 was 18.0N.

Therefore, it can be said that the tensile strength in the lateral direction X of the lower portion 21 (crotch region 13 ) is higher than the tensile strength in the lateral direction X of the upper portion 22 of the shorts body 20 . In addition, since the lower part 21 could not be pulled up to 50 mm from the starting position in the measurement, the tensile strength at the distance of 50 mm could not be measured. From these measurement results, it can be said that the upper band 30 is more likely to stretch in the lateral direction than the upper portion 22 of the shorts body 20, and the upper portion 22 is more likely to stretch in the lateral direction than the lower portion 21.

Unless otherwise specified, for the members constituting the sanitary shorts 10, in addition to the materials described herein, known materials commonly used in this type of field may be used without limitation. can be done.
