Description

Panties {PANTY}

The present invention relates to a panty that closely adheres the sanitary napkin to the crotch portion, and in detail, a thick sanitary napkin for night is firmly maintained in the crotch portion to prevent misalignment, and excellent discomfort due to pressure on the wearer's body It's about panties that don't give much.

The panties are required to keep the sanitary napkin securely and firmly attached to the crotch portion, to prevent displacement of the sanitary napkin from the crotch portion, and to reduce the feeding of the sanitary napkin into the crotch portion of the body to provide comfort to the wearer.

With this type of panties, there is a large capacity to withstand tensile loads in the central region of the front and rear portions, the crotch portion located between the front and rear portions and connecting the front and rear portions, and a pair of elastic leg openings. A panty with a was disclosed (JP-2001-522958A). This panty has a longitudinal elongation control member disposed in the crotch region, and the elongation control member is disposed on both the front part and the rear part to extend from the longitudinal elongation control member to the waist band. The inventors of the present invention have provided a comfortable panty that prevents the sanitary napkin from sticking to the crotch portion to prevent the sanitary napkin from being fed into the crotch portion (JP-A-2002-660). This panty includes a waist band around the waist opening, a leg band around the leg opening, and is used as a portion where the crotch is attached to the sanitary napkin. When the panties are measured in a three-dimensional state when worn, the ratio of the dimensions between the center length from the crotch to the waist opening and the side length from the leg opening to the waist opening is 100 when the center height length is 100. The side height is in the range of 80 to 200, characterized in that the stretch member is formed from the crotch portion to the waist opening of the rear portion.

However, in the case of the panties disclosed in JP-T-2001-522958, although the sanitary napkin located in the crotch region can be firmly adhered to the body by the kidney control member, since the kidney control member is provided in a narrow strip, the force is Concentrated on one linear point, panties can be fed into the body when worn. In addition, the sanitary napkin may be bent in the center to form a shape that rises upward, which may cause discomfort to the wearer's body.

Moreover, since two telescopic leg openings are formed by suturing the front and rear portions together, the sealed portion extends at the center of the crotch portion to connect the two leg openings. Therefore, when the sanitary napkin is attached to the panties, there is no basis for keeping the sanitary napkins stable, and consequently, the sanitary napkins may be twisted in a narrow form or the adhesive parts of the sanitary napkins may be peeled off from the panty body to cause problems related to leakage.

In the case of the panties disclosed in JP-A-2002-660, the elastic pulling member formed on the rear portion is elongated in the longitudinal direction to generate an elastic contractive force. This resilient contraction acts almost linearly in the middle of the posterior region, along the spinal cord and into the gluteal and crotch portions. Therefore, a large pulling force in the front and rear direction occurs in the crotch portion, and the sanitary napkin of the crotch portion presses the vaginal ball.

This panty has a structure in which the stretchable pulling member formed on the rear portion is elongated in the longitudinal direction to generate a stretchable pulling force for bringing the sanitary napkin into close contact with the body. However, since the stretch pull member is disposed on the rear portion and the front portion is formed of a sufficient stretch cloth, when the night-thick sanitary napkin is attached to the panties, the sanitary napkin is placed up with the stretch pull member disposed on the rear portion. Even when the sanitary napkin is brought into close contact with the body, since the sanitary napkin is thick and rigid, the elastic lifting member is stretched, and the sanitary napkin cannot be properly applied to the hip or crotch part because the urging pad is not properly applied.

Therefore, a gap is created between the sanitary napkin and the body, and the menstrual blood flows down the rear side and leaks out of the sanitary napkin. In addition, the problem that the acupuncture points spread through the gap to increase the skin area in contact with the acupuncture points is a burden on the skin and may cause skin irritation.

Because the wearer moves involuntarily during sleep, when the body is pressed with a strong girdle, for example, to prevent displacement or twisting of the sanitary napkin, this is caused by swelling or hematopoietic disease caused by tightening, which causes significant stress on the body. May result.

Therefore, panties having a structure that does not press the entire body but can be pressed against the body by pressing only the necessary portion of the sanitary napkin are preferable.

It is an object of the present invention to easily adhere to a thick sanitary napkin at night to the crotch portion or gluteal fever, to prevent misalignment, to prevent being fed into the crotch portion, and to provide a panty that gives comfort to the wearer without discomfort due to compression It is.

In view of the above problems of the related arts, the present invention provides a panty having a crotch portion formed of a highly elastic member made of a highly elastic material and a micro elastic member made of a micro elastic material, and formed to bridge the front part and the rear part. . The micro stretch member is formed in the central region of the rear portion from the rear end of the crotch portion to the waist retention portion. The longitudinal elongation coefficient of the microelastic member is set to be greater than the longitudinal elongation coefficient of the highly elastic member covering the hips and abdomen around the central region. A micro-stretch member of the rear portion sealed by the sanitary napkin lifting portion is formed in the center of the crotch portion, and its longitudinal extension coefficient is set to be greater than the longitudinal extension coefficient of the crotch fabric constituting the crotch portion covering the crotch portion. The above-mentioned problem can be solved by completing the present invention with the above-mentioned structure.

More specifically, the present invention provides the following.

(1) panties formed of a high elastic member made of a high elastic material and a micro elastic member made of a micro elastic material, the front part; Rear part; A crotch portion formed to bridge between the front portion and the rear portion; A waist opening formed at an upper edge of the front portion and an upper edge of the rear portion; And a pair of leg openings formed below both side edges of the front part and both side edges of the back part, wherein the band-shaped area formed from the crotch part to the waist opening part and formed in the substantially central area of the back part is formed of the micro stretchable member.

According to the present invention, when pulled up to wear the panties, a micro-stretch member assigned to the band-shaped area is provided from the crotch to the waist and acts to pull the crotch connected to it without stretching. As a result, the sanitary napkin attached to the crotch portion is pulled up to be in close contact with the crotch portion of the body and the gluteal cleft, and almost no gap is generated between the sanitary napkin and the body to prevent leakage of menstrual blood. Since the panty is composed of a highly elastic, highly elastic member, it is comfortable to wear because it does not cause the discomfort of pressing the wearer's body like wearing a girdle. Since the crotch part formed so as to bridge between the front part and the rear part when worn is located around the pubic bone and the anus, the sanitary napkin can be stably attached to the crotch part when wearing panties with a sanitary napkin attached to the crotch part, The sanitary napkin will not twist, avoiding the risk of leaking menstrual blood.

In the present invention, the front portion refers to the front portion of the panty body covering the abdomen, and the rear portion refers to the rear portion of the panty body covering the back side of the waist. The panty body refers to a portion covering the waist of the body. The term "crotch portion formed to bridge between the front portion and the rear portion" refers to the crotch portion formed by connecting the crotch cloth by the method such as stitching the front portion and the rear portion, and does not mean the crotch portion formed by connecting the front portion directly to the rear portion. Do not.

(2) The present invention provides panties according to (1), wherein the longitudinal extension coefficient of the micro stretchable member is larger than the longitudinal extension coefficient of the high stretch member.

According to the present invention, when the wearer attaches the sanitary napkin to the sanitary napkin close fabric and pulls it up to wear the panties, the micro-stretch member is pulled up starting from the portion where the micro-stretch member is sealed between the crotch portion and the micro-stretch member. At this time, the force to pull up the micro-stretch member acts as a force to pull up the crotch portion, and acts as a force to float the night sanitary napkin attached to the sanitary napkin adhesion cloth. In this case, since the longitudinal elongation coefficient of the micro-stretch member is larger than that of the high-stretch member disposed around the micro-stretch member, the force to float the sanitary napkin up the crotch portion connected to the micro-stretch member and also the sanitary napkin attached to the crotch portion. It works effectively by pulling force. Therefore, unlike the panties having elasticity in the rear center region as in the prior art, even when the waist opening is held and the panties are pulled up, only the central region of the rear portion is elongated and it is difficult to work sufficiently as a force for pulling up the sanitary napkin. According to the panties can be closely adhered to the crotch portion and gluttony at night thick sanitary napkin.

Preferably, the longitudinal elongation coefficient of the micro stretchable member is about 10N to 60N, more preferably 20N to 50N. If the elongation coefficient is less than 10N, the force to float the sanitary napkin is not sufficient, and it does not act effectively as the force to float the sanitary napkin. In this case, when the wearer pulls the panties up, the micro-stretch member is stretched too much so that the force exerted by the wearer does not act effectively as the force to pull up the sanitary napkin. Elongation modulus greater than 6 ON tends to generate a pulling force greater than the force required to adhere the sanitary napkin, and consequently, the sanitary napkin may be eaten by the body more than necessary, resulting in discomfort or pain, which is undesirable. For example, non-stretchable materials, such as plastic tapes or laces, are undesirable because the force to pull up the panties acts directly as a force to pull the sanitary napkin up, causing the sanitary napkin to overeat into the body's gaps.

The longitudinal direction of the micro-elastic member and the longitudinal direction of the highly elastic member correspond to the direction in which the panties are pulled up and down (Y-direction in FIGS. 1 and 2), and the waist direction at the crotch and leg openings. The crotch portion refers to the body part between the legs and includes such parts as the vaginal opening, perineum, and anus. The elongation coefficient means the tensile load when the members of the panties (micro stretch member, high stretch member, sanitary napkin lifting portion, and fixing member) are pulled up and divided by the elongation rate at that time. The larger it is, the more difficult it is to stretch.

(3) the present invention; Rear part; Sanitary napkin close crotch formed to bridge between the front and rear portions; A waist opening formed at an upper edge of the front portion and an upper edge of the rear portion; And a pair of leg openings formed under both side edges of the front part and both side edges of the back part, wherein the sanitary napkin lifting part is formed at the center of the crotch part from the front part to the rear part, and the longitudinal elongation coefficient of the sanitary napkin lifting part is the crotch part. Provides panties that are greater than the crotch fabric's longitudinal elongation factor.

According to the present invention, since the longitudinal elongation coefficient of the sanitary napkin lifting portion is greater than the surrounding crotch fabric, the sanitary napkin pulling portion is pulled up with a force greater than the force pulling the surrounding fabric upwards, thereby removing the central portion of the sanitary napkin attached to the crotch portion (body It acts as a pulling force). The elasticity of the sanitary napkin lifting portion has an elongation coefficient of 5N to 30N, more preferably 10 to 25N. If the elongation coefficient is less than 5N, the force of floating the central portion of the sanitary napkin does not act effectively on the force of pulling up the micro stretch member. As described in (1), since the crotch is provided to be bridged between the anterior part and the posterior part, it is located around the back of the pubis and anus when worn. Therefore, when the wearer attaches the sanitary napkin to the crotch portion and wears panties, the sanitary napkin can be stably attached to the crotch portion, so that the sanitary napkin is not twisted, thereby avoiding the risk of leakage of menstrual blood. In the case of providing a waterproof waterproof cloth inside the crotch fabric constituting the crotch portion, along with the crotch fabric and the suture portion for sealing the front portion or the rear portion, the tarpaulin cloth with the crotch fabric and the front portion, or with the crotch fabric and the rear portion Can be sealed together. Therefore, the number of the sutures does not increase, so that an uncomfortable feeling of wear and appearance damage can be prevented. The longitudinal direction of the sanitary napkin lifting portion is the direction lying between the front part and the rear part.

(4) the present invention; Rear part; Sanitary napkin close crotch formed to bridge between the front and rear portions; A waist opening formed at an upper edge of the front portion and an upper edge of the rear portion; A pair of leg openings formed under both side edges of the front part and both side edges of the rear part; And a micro-stretch member made of a micro-stretch material formed in a highly stretched member made of a highly stretchable material, wherein the micro-stretch member is formed in a substantially central region of the rear portion from the crotch portion to the waist opening, and the sanitary napkin lifting portion is placed forward. The micro-stretch member and the sanitary napkin lifting portion are stitched together at the ends of the crotch portion on the side of the rear portion, the longitudinal stretch coefficient of the micro-stretch member being greater than the longitudinal stretch coefficient of the high stretch member. It provides a panty in which the longitudinal elongation coefficient of the sanitary napkin lifting portion is greater than the longitudinal elongation coefficient of the crotch fabric constituting the crotch portion.

According to the present invention, as described above in (2) and (3), the force of pulling up the micro-stretch member when wearing panties acts as the force of pulling up the sanitary napkin lifting portion. The sanitary napkin lifting portion is pulled upward with a force greater than the pulling force of the fabric constituting the crotch portion around it, and acts as a force for pulling up the central portion of the sanitary napkin attached to the crotch portion (in the direction of the crotch portion of the body). Therefore, the sanitary napkin is fixed to better adhere to the crotch portion. As described in (1), since the crotch is provided to be bridged between the anterior part and the posterior part, it is located around the back of the pubis and anus when worn. Therefore, when the wearer attaches the sanitary napkin to the crotch portion and wears panties, the sanitary napkin can be stably attached to the crotch portion, so that the sanitary napkin is not twisted, thereby avoiding the risk of leakage of menstrual blood.

(5) The present invention provides the panties described in any one of the above (1) to (4), wherein the crotch portion is formed by a crotch fabric sealed to the front portion and the rear portion.

According to the invention, a suture is present between the lower end of the anterior part and the front end of the crotch fabric, and between the lower end of the rear part and the rear end of the crotch fabric, and in the middle portion of the crotch portion in the width direction (a pair of leg openings and In the opposite direction). That is, each suture is placed around the back of the pubis and anus when worn. Therefore, when the wearer attaches the sanitary napkin to the crotch portion and wears panties, the sanitary napkin can be stably attached to the crotch portion, so that the sanitary napkin is not twisted, thereby avoiding the risk of leakage of menstrual blood.

(6) The present invention provides a panty according to any one of the above (1) to (5), wherein the panty further includes a waist holding portion formed by extending from the rear to the front around the waist opening. .

According to the present invention, the waist retaining portion distributes the force of pulling up the micro-stretch member and the force of fixing the fixing member to the side of the panty (in the width direction), and maintains this force at the waist so that the panty is in the width region. Close to the waist area over.

(7) The present invention provides a panty according to any one of the above (1) to (6), wherein the panty is almost centered on the outer side of the high elastic member, at the center of the front portion stitched to the high elastic member, the waist holding portion, and the crotch portion. It provides a panty that includes a fixing member in the area.

According to the present invention, by the force provided by the micro-stretch member that is pulled up when wearing the panties, the fixing member can control the stretch of the highly elastic member when the sanitary napkin lifting portion is pulled toward the rear portion. Accordingly, since the portion of the sanitary napkin lifting portion disposed on the front side side is fixed without being pulled under the influence of the sanitary napkin lifting portion and the micro stretchable member, the force for pulling the micro stretchable member acts as a force for directly pulling up the sanitary napkin lifting portion. As a result, the sanitary napkin is pulled up toward the body to better adhere to the crotch portion and the gluteal cleft.

(8) The present invention provides a panty according to any one of the above (1), (2), (4) to (7), wherein the micro stretchable member is formed of a material that is inelastic in the longitudinal direction. do.

According to the present invention, since the micro-stretch member is hardly stretched in the longitudinal direction, when a night sanitary napkin is attached to a sanitary napkin adhesion cloth and the panties are pulled up for wearing, the pulling force is effectively applied by the force of floating the sanitary napkin. Works. The micro-stretch member that can be used in the present invention is a cloth formed of a knitted fabric such as nylon fiber or polyester fiber, and does not include an elastic member such as polyurethane fiber in the longitudinal direction, and some stretchability is caused by the change of the floating structure. Although it has, there is no elasticity by the property of a member.

(9) The present invention provides a panty according to any one of (3) to (8), wherein the sanitary napkin lifting portion is formed of a material that is inelastic in the longitudinal direction.

According to the present invention, since the sanitary napkin lifting part is almost elastic in the longitudinal direction, when the panties are pulled up for wearing, the sanitary napkin lifting part is stronger than the cloth around it by the pulling force transmitted from the micro stretching member. This upward pull acts as a force to pull up the central part of the sanitary napkin. The sanitary napkin lifting portion used in the present invention is a fabric formed of a knitted fabric such as nylon fiber or polyester fiber, similarly to the micro stretchable member, and does not include an elastic member such as polyurethane fiber in the longitudinal direction, and is used to change the knit structure. There is some elasticity by this, but it does not have elasticity by the property of a member.

(10) The present invention provides a panty according to any one of (3) to (9), wherein the panty stretch factor of the sanitary napkin lifting portion is smaller than that of the microscopic stretching member.

When wearing the panties, the micro-extension member in the rear portion acts to keep the sanitary napkin close to the body while stretching the sanitary napkin lifting portion of the crotch portion. In the case where the sanitary napkin lifting portion has a greater elongation coefficient than the microscopic stretching member, when the panties are pulled up, the sanitary napkin lifting portion is not stretched, and the microscopic stretching member at the rear is stretched, and hardly acts by the force of pulling the sanitary napkin upward toward the body. .

(11) The present invention provides a panty according to any one of (3) to (10), wherein the width of the sanitary napkin lifting portion is narrowed from the front part to the rear part.

According to the present invention, the sanitary napkin lifting portion is pulled toward the rear by the force of pulling up the micro-stretch member, and acts as a force to float the sanitary napkin up (toward the crotch portion of the body) to bridge with the gap of the body. In this case, the width of the sanitary napkin lifting portion, which is the widest part, is gradually narrowed toward the vaginal, perineal and anal portions, from the portion where the sanitary napkin lifting portion is connected with the anterior portion (the portion in contact with the peri- pubic portion). Therefore, upward force acts along the centerline of the sanitary napkin attached to the crotch portion. When the width of the portion where the fixing member is connected to the front portion is almost the same as the width of the crotch portion, the portion of the pant to which the pubic circumferential portion contacts is stabilized, and the center around the vaginal fold is centered. If the lateral width of the fixing member is narrow, such as the perineum or the perianal part, it is not preferable because the center of the sanitary napkin may be distorted at the time of wearing and distorted at the center of the vaginal opening.

The width of this sanitary napkin lifting portion is narrowed toward the vaginal and perineal region from the portion where the fixing member, which is the widest portion, is connected to the anterior part (the portion in contact with the body part around the pubic bone), and further from the portion around the vaginal opening. It can be increased to the area around the anus, provided it is narrower than the width of the seamed portion of the fixation member.

(12) The present invention provides panties according to (11), wherein the width of the sanitary napkin lifting portion is 20 mm to 60 mm.

According to the invention, since the width of the sanitary napkin lifting portion is not assumed to be a thin line, the force is not concentrated at one point. Therefore, the possibility that the sanitary napkin is fed into the body when worn and formed to be bent up from the center to form a raised shape may be reduced when the sanitary napkin is attached to the sanitary napkin close cloth, which may cause inconvenience to the wearer.

(13) The present invention provides panties according to any one of the above (7) to (12), wherein the longitudinal elongation coefficient of the fixing member is larger than the longitudinal elongation coefficient of the highly elastic member.

According to the invention, the fastening member acts as a force for fixing the part of the panties which the peri pubic portion contacts at the center of the anterior part. However, since the longitudinal elongation coefficient of the fixing member is larger than the longitudinal elongation coefficient of the highly elastic member, it is controlled that the front portion is elongated in the longitudinal direction. Since the elongation is controlled by the fixing member, the central area of the anterior part is not elongated under the influence of the micro-elastic member or the sanitary napkin lifting portion, so that the part of the panties that the pubic bone contacts is fixed. The longitudinal elongation coefficient of the fixing member is 10N to 30N, more preferably 15N to 25N. This is because the part of the front part corresponding to the abdomen is a part which is greatly deformed by the movement of the body. When the cloth is not stretched at all, the waist part of the upper end of the front part flows downward, thereby impairing the adhesion. The fixing member is formed of a power net composed of nylon fibers or polyurethane fibers.

In the present invention, the longitudinal direction of the fixing member means a direction in which the panties are pulled up and down when worn, that is, the waist direction (Y-direction in FIG. 2) from the crotch to the leg opening.

(14) The present invention provides a panty according to any one of (1), (2), (4) to (13), wherein the upper end of the micro-stretch member is substantially V-shaped on the waist opening side. It provides a panty that is to be sutured.

According to the present invention, the length of the fabric constituting the micro-stretch member from the waist holding portion to the crotch portion is the length from the center of the V-shaped (V-shaped center point) that is sutured with the waist holding portion to the crotch portion. It is shorter than the end. Since the elongation amount at the time of elongation of the fabric is larger than the elongated portion of the shorter fabric, when the micro-stretch member is pulled up, the portion from the center portion of the V-shaped to the crotch portion is pulled up with a stronger force than the left and right ends thereof. Thus, the central portion is not loose, and a force for pulling up the sanitary napkin is generated.

(15) The present invention provides a panty according to any one of (6) to (13), wherein the top end of the fixing member on the waist opening side is substantially V-shaped with the waist retaining portion. .

According to the present invention, the length of the fabric constituting the fixing member extended from the waist holding portion to the crotch portion is shorter than the left and right ends of the center (V-shaped sharp top) length of the fixing member. Since the shorter side of the fabric has a larger amount of elongation than the long portion, when the fastening member is pulled up, the central portion of the fastening member is pulled up with a stronger force than its left and right ends. Thus, the central portion is not loose, and a force for pulling up the sanitary napkin is generated.

(16) The present invention provides a panty according to any one of (1) to (15), wherein the crotch portion includes a sanitary napkin adhesion cloth therein, wherein the front and rear ends of the sanitary napkin adhesion cloth are sealed with the crotch portion, and the sanitary napkin adhesion The lateral ends of the fabric provide panties that are not sewn to the crotch.

According to the present invention, the sanitary napkin closely sutures only the front and rear ends of the crotch portion and is not completely coupled to the crotch portion, that is, inside the crotch portion, independent of the crotch portion. Accordingly, the sanitary napkin closely adheres to the crotch portion and does not extend in the front-back direction (in the front and rear portions), and even when it is stretched, the amount of elongation is small, so that the sanitary napkin attached thereto can be reliably maintained. In addition, since it is closed at the crotch portion and the front and rear ends, it can be closed together with the crotch fabric constituting the crotch portion. Therefore, the number of the sutures does not increase, and discomfort or appearance damage during wearing can be prevented. The front and rear ends mean the ends of the sanitary napkin adhered fabric on the sides of the front part and the rear part.

(17) The present invention provides panties according to (16), wherein the length of the sanitary napkin adherent fabric is the same as or longer than the length of the crotch fabric constituting the crotch portion.

According to the present invention, when the panties are pulled up for wearing, even if the crotch portion formed of the elastic crotch fabric is elongated, the length of the sanitary napkin adherent cloth is long enough not to elongate. Alternatively, even if it is elongated, since the amount of elongation is small, the sanitary napkin can be surely maintained. When the crotch portion is extended, the sanitary napkin lifting portion is pushed toward the crotch portion, and the sanitary napkin is pushed onto the crotch portion.

(18) The present invention provides a panty according to any one of the above (1), (2), (4) to (17), wherein the elasticity is stretched from the high elastic member to the micro elastic member at the boundary between the high elastic member and the micro elastic member. Provides panties that are gradually decreasing.

According to the present invention, when the pants are pulled up for wearing, since the elasticity gradually decreases from the high-stretching member, the elongation of the micro-stretching member gradually decreases, so that the panties can adhere to the wearer's body without causing discomfort. have.

(19) The present invention provides the panties according to any one of (1), (2), (4) to (17), wherein the elasticity is stretched from the high elastic member to the micro elastic member at the boundary between the high elastic member and the micro elastic member. Provides panties that are discontinuously changing.

By discontinuously changing the elasticity of the micro stretchable member from the high stretch member to the micro stretch member, the high stretch member and the micro stretch member are clearly divided. Compared with the case where they are not clearly divided (ie when the elasticity is continuously changed), the adhesion may be reduced, but the effect of raising the sanitary napkin is enhanced.

(20) The present invention provides the panties according to any one of (1) to (19), wherein assuming that the panties are in a three-dimensional shape, the center height length from the crotch portion to the waist opening, and the leg opening to the waist opening The dimension ratio between the lateral height length, which is the shortest length of, provides a panty, wherein the lateral height length is 80 to 200 when the median height length is viewed as 100.

According to the present invention, because the side height length of the panties is long, the leg bands formed in the leg openings tighten the thighs of the wearer rather than tightening from the portion around the crotch to the lumbar spine. Therefore, because the apparent pulling force generated by the leg band does not act on the crotch portion, feeding into the crotch portion does not occur. In addition, since the great pulling force generated by the leg band does not act on the crotch portion, the sanitary napkin of the crotch portion is reliably floated upward by the micro-stretch member provided on the rear portion, thereby making it more closely adhered to.

(21) The present invention provides a panty according to any one of the above (1) to (20), wherein the micro-stretch member, the sanitary napkin lifting portion, and the waist retaining portion exhibit a color tone or gloss different from that of the highly elastic member. to provide.

According to the present invention, since the micro-stretch member, the sanitary napkin lifting portion, and the waist retention portion have a different color or texture than the high stretch member, they can be identified by the eye. As such, the waist retaining portion, the micro stretch member, and the sanitary napkin lifting portion stand out, so that the wearer can easily recognize the pulling member, and the effect of the pulling member can be easily understood. Since this pulling member formed at the center of the panty has a different appearance from other fabric members, when the wearer attaches and positions the sanitary napkin to the panty, the center of the sanitary napkin and the center of the panty are easily listed so that the center of the sanitary napkin is It may be in close contact with the center of the crotch portion. Accordingly, the effect of blocking the gap that prevents leakage of liquid such as acupuncture points can be improved.

(22) The present invention provides a panty according to any one of the above (1) to (21), wherein the panty includes an instruction indicating how to wear the front part or the rear part.

According to the present invention, the wearer can control the adhesion of the sanitary napkin by looking at the instructions, when the wearer attaches the sanitary napkin to the sanitary napkin adhesion cloth of the panty through an adhesive or the like, and tries to wear the panty up to a predetermined position of the body, Grab the upper side of the panties and pull the fabties up. In addition, this method of wearing can provide some adhesion to the sanitary napkin. However, since the desired degree of adhesion varies from person to person, a person who wants to be in close contact may, for example, see an instruction saying, "If you want to be in close contact, pull the part located on the extension line of the micro-stretch member at the center of the rear part." You can control the degree. As such, it helps the person who wants strong adhesion to easily understand how to wear.

(23) The present invention provides panties according to (22), wherein the instructions are provided near a waist opening above the micro stretch member.

According to the invention, the sanitary napkin can be tighter by pulling up the pointing portion. That is, by holding the upper side portion of the panties, wearing the panties, and pulling the portions upwards, the micro-stretch members are pulled up. By pulling up the micro-stretch member, the sanitary napkin can be pushed toward the crotch portion of the body, as described above, so that higher adhesion can be obtained.

As shown in FIGS. 1 to 4, the panty 10 has a front portion 11, a rear portion 12, and a crotch portion 13 positioned between the front portion 11 and the rear portion 12. The waist opening 14 is formed at the upper edge of the front portion 11 and the upper edge of the rear portion 12, and a pair of leg openings 15 are formed below the front portion 11 and the rear portion 12. , The sanitary napkin adhesion cloth 16 (shown in FIG. 8) to which the sanitary napkin is attached is disposed inside the crotch portion 13. The waist retaining portion 17 extending from the front portion 11 to the rear portion 12 is formed around the waist opening 14 and has a micro stretchable member extending from the crotch portion 13 to the waist holding portion 17 ( 18 is disposed in the central region of the rear part 12. The highly stretchable member 19 is disposed throughout the other regions of the front portion 11 and the rear portion 12 except for the waist retaining portion 17 and the fixing member 20, and is provided almost at the front portion 11. Sutured in the center. A portion of the high stretch member 19 disposed in the rear portion 12 forms a rear side high stretch member 19b extending from the micro stretch member 18 to the front portion 11. Another portion of the high stretch member 19 disposed in the front portion 11 forms the front side high stretch member 19a. A fixing member 20 is provided in the central region of the front portion 11, and the fixing member 20 is sealed with the high stretching member 19. The high elastic member 19 is also sutured in the crotch portion 13 and the waist retaining portion 17 and in the front portion 11 and the rear portion 12. And the sanitary napkin lifting part 21 is provided in the center of the crotch part 13 which bridges the micro stretch member 18 with the fixing member 20. As shown in FIG. A waist band 22 is provided along the upper side of the waist retaining portion 17 formed at the upper edges of the front portion 11 and the rear portion 12, and a leg band 23 is provided around the leg opening 15. do. The dimension ratio between the median height length La from the crotch portion 13 to the waist opening 14 and the lateral height length Lb, which is the shortest length from the leg opening 15 to the waist opening 14, is the center height. With a length of 100, it is in the range of 80 to 200.

The highly stretchable member 19 may be formed into a knit fabric, such as a combination of nylon fibers and polyurethane fibers, a combination of polyester fibers and polyurethane fibers, or a combination of nylon fibers, polyester fibers and polyurethane fibers. Combinations other than the foregoing may also be used if the elongation coefficient does not exceed 10N. The crotch portion 13 is formed by the crotch fabric 24, and the crotch fabric 24 is sutured with the highly elastic member 19 at the side of the front portion 11 and the side of the rear portion 12. Similar to the high stretch member 19, the crotch fabric 24 may be a combination of nylon fibers and polyurethane fibers, a combination of polyester fibers and polyurethane fibers, or a combination of nylon fibers, polyester fibers and polyurethane fibers, It may be formed of an elastically stretchable knitted fabric. The waist band 22 formed along the waist opening 14 and the leg band 23 formed along the leg opening 15 are formed of an elastic material such as a stretch knit of polyurethane fiber, synthetic rubber sheet or natural rubber sheet. In the present invention, the longitudinal direction is the direction when the waist opening 14 and the crotch portion 13 are defined as the upper side and the lower side (Y-direction in FIG. 1), that is, pulling the panties 10 up and down when worn. Direction, and the lateral direction means a direction perpendicular to the longitudinal direction (X-direction in FIG. 1), that is, the width direction of the panties 10.

The waist holding portion 17 is formed with a V-shaped edge which is a sharp edge toward the center of the front portion 11 and the rear portion 12 along the waist opening 14 of the panty 10. It is sealed with the highly stretchable member 19 of the rear part 12. The waist holding portion 17 is a knitted fabric in which the longitudinal elongation coefficient is larger than the lateral elongation coefficient. Such knitwear is, for example, a combination of nylon fibers and polyurethane fibers, a combination of polyester fibers and polyurethane fibers, or a combination of nylon fibers, polyester fibers and polyurethane fibers. The waist band 22 formed around the waist opening 14 is, for example, a polyurethane band, a natural rubber band, or a synthetic rubber band of about 10 mm, and is closed with the waist retaining portion 17 in an extended state.

The waist holding portion 17 distributes the force of pulling up the sanitary napkin lifting portion 21 through the micro elastic member 18 or the fixing member 20, and maintains the force at the waist portion, thereby providing a panty 10. In wearing, it is preferable that the longitudinal extension of the waist holder 17 is limited so that the waist holder 17 is held and fixed to the waist portion. It is preferable that its lateral elongation coefficient is greater than the lateral elongation coefficient of the high-stretch member 19, because the force for pressing the waist opening 14 is increased, thereby preventing the panty 10 from flowing down.

The micro stretchable member 18 is provided in an almost central region of the rear portion 12. The upper end of the micro stretchable member 18 is sealed with the central portion of the waist retaining portion 17 (near the sharp edge of the V-shaped edge), and the lower end of the micro stretchable member 18 is formed of the rear portion 12. On the side (rear end of the crotch portion 13), the end of the crotch portion 13 is closed, and both side ends of the micro stretchable member 18 are closed with the high elastic member 19. The micro stretchable member 18 extends from the waist holding portion 17 to the rear end of the crotch portion 13 and narrows toward the rear end of the crotch portion 13. The width of the narrow portion is in the range of 10 mm to 30 mm, preferably about 20 mm. The width of the wide portion where the micro stretchable member 18 is sewn with the waist retaining portion 17 is in the range of 30 mm to 130 mm, preferably about 60 mm. The micro stretchable member 18 may extend to the waist opening 14.

The length of the central region of the micro stretchable member 18 (corresponding to Lc in FIG. 1) is shorter than the side end length of the micro stretchable member 18 (corresponding to Ld in FIG. 1), and the upper portion of the micro stretchable member 18. The distal end and the rear distal end of the waist retention portion 17 are sutured to form a V-shaped portion having the aforementioned V-shaped edges. Therefore, when the panties 10 are worn, the fabric located in the central region of the micro stretchable member 18 extending from the sharp edge of the V-shaped portion to the crotch portion 13 is less than the fabric located at the lateral end of the micro stretchable member 18. Stretches more. That is, the stretching force which pulls up the cloth located in the center area | region of the micro stretch member 18 is larger than the force which pulls up the cloth located in the side edge part of the micro stretch member 18. As shown in FIG. When the micro stretchable member 18 is pulled up, since the length of the central region of the micro stretchable member 18 is shorter than the side end length of the micro stretchable member 18, the fabric located in the central region is located at its left and right ends. The fabric is pulled up with a force greater than that of pulling it up. Thus, the central portion does not loosen, and a force for pulling up the sanitary napkin 25 is generated. Regarding the relationship between these lengths, the dimension and the elongation rate were measured before and after wearing the panties 10 on the doll. Dimensions and elongation are shown in Table 1. As shown in Table 1, the length in the central region of the micro stretchable member 18 is shorter before wearing the panty 10, and the elongation is greater when worn.

The micro-stretch member 18 is a combination of nylon fibers and / or polyester fibers, a combination of nylon fibers and polyurethane fibers, a combination of polyester fibers and polyurethane fibers, or a combination of nylon fibers, polyester fibers, and polyurethane fibers. It can be formed into a knitted fabric such as a combination. The fabric forming the micro stretch member 18 is somewhat stretchy caused by the knit structure, but does not have stretch caused by the material itself, i.e., does not have a stretchable material such as polyurethane fibers in the longitudinal direction, In other words, it is a cloth having a longitudinal elongation coefficient larger than the longitudinal elongation coefficient of the highly stretchable member 19. Therefore, the micro stretchable member 18 can hardly be extended as compared with the high stretch member 19. In this structure, the highly elastic member 19 covering the surrounding hips or abdomen is formed of a stretchable fabric both longitudinally and laterally, in accordance with the deformation of the body caused by the wearer's movement. However, the micro-stretch member 18 provided in the almost central region of the rear part 12 is hardly affected by the movement of the high-stretch member 19, which has a longitudinal expansion coefficient of which the stretch of the high-stretch member 19 is performed. Because it is larger than the coefficient.

The stretchability of the micro stretchable member 18 is preferably 10N to 60N, more preferably 20N to 50N. If the elongation coefficient is less than 10 N, the force to pull up the sanitary napkin 25 is not sufficient, and if the elongation coefficient is larger than 60 N, the sanitary napkin 25 may be fed too strongly into the body gap (FIG. 11). Even if the micro-stretch member 18 is not stretched at all, the force to pull up the panties 10 directly acts as a force to pull up the sanitary napkin 25 so that the force to pull up the sanitary napkin 25 is in close contact with the sanitary napkin 25. Larger than the required force, the sanitary napkin 25 is excessively fed into the body, which may cause discomfort or pain, which is undesirable. On the contrary, when the elasticity is too large, when the wearer pulls the panties 10 upward, the micro elastic members 18 are excessively stretched and do not act effectively by the force pulling the sanitary napkin 25 upwards.

On the other hand, the elongation coefficient of the high-stretch member 19 is preferably smaller than 10 N, more preferably 2 N to 3 N at 10 to 30% elongation. Specifically, the tensile load is about 0.4 to 0.6 N at about 20% elongation when the panty is worn, so it is gently adhered along the body. Elongation factor when worn means the elongation coefficient obtained by wearing panties on a doll of medium size.

The micro stretchable member 18 may be formed to have the same elongation rate throughout the region, or as shown in FIG. 5, so that the elongation rate may be gradually or discontinuously changed so as to reduce the elongation from the left and right ends toward the central region. Can be. FIG. 5 shows an expanded form of the micro stretchable member 18, which schematically shows a state in which its elongation is gradually changed from the left and right ends 18a to the central region 18b.

For reference, the relationship between the tensile elongation and the elongation rate of the micro stretchable member 18 of the panty 10 according to the present invention is shown in FIG. 12 in comparison with the panties of the prior art. In Figure 12, the vertical axis represents the tensile load in Newtons (N) and the lateral axis represents the elongation in%. Curve A corresponds to panties according to the invention and curve B corresponds to panties of the prior art.

As shown in Fig. 12, when the micro-stretch members provided in the nearly center region of the rear portion of the panties of the prior art are stretched 30%, the tensile load is P1. On the other hand, when the micro stretch member 18 of the panty 10 according to the present invention is stretched 30%, the tensile load is P2, which means that the panty 10 of the present invention has a greater tensile strength than the panties of the prior art. Indicates. That is, the panty 10 of the present invention has a greater tensile load than the panties of the prior art having the same elongation. Even when the panty 10 according to the present invention stretches only 10% when worn, the tensile strength applied to the panty 10 of the present invention is P3, which is larger than the tensile strength of the panties of the prior art. That is, even when the elongation rate is smaller than that of the prior art panties, the tensile strength applied to the panties 10 of the present invention is larger, which means that the micro-stretch members 18 of the panties 10 of the present invention are crotch portions 13. It means that it works effectively by pulling force. Thus, the force to pull up the night sanitary napkin 25 is increased, so that the sanitary napkin 25 is in close contact with the crotch portion of the body.

The fixing member 20 of the pant 10 is formed of a power net and is disposed in an almost center region of the front portion 11. Its upper end is sealed with the waist retaining portion 17 around the sharp edge of the V-shaped portion of the waist retaining portion 17, the side edge of which is sealed on the high elastic member 19. Its lower end is closed with the sanitary napkin sticking cloth 16 constituting the sanitary napkin lifting part 21 and the crotch part 13, or the end of the crotch part 13 on the side of the front part 11 (the crotch part 13). Sutures) with the high stretching member 19 at the front end). The fixing member 20 is narrowed from the waist holding portion 17 toward the crotch portion 13 and is closed with the sanitary napkin lifting portion 21 disposed almost at the center of the crotch portion 13. The width of the portion where the fixing member 20 is sealed with the sanitary napkin lifting portion 21 is approximately equal to the width of the front end of the sanitary napkin lifting portion 21 disposed on the side of the front portion 11. The upper end closed with the lumbar retainer 17 is formed substantially V-shaped, the width of which is 60 mm to 150 mm, preferably 80 mm to 120 mm.

The length of the central portion of the fixing member 20 (corresponding to Lc in FIG. 1) is shorter than the length of its left and right side ends (corresponding to Ld in FIG. 1), and the upper end and the waist holding portion ( The rear end of 17) is sutured to form a V-shaped portion as described above. Therefore, as in the case of the micro-stretch member 18, when the fixing member 20 is pulled up, the central portion of the fixing member 20 is pulled up with a force stronger than the force pulling up the left and right side ends thereof ( See Table 1). Thus, the central portion is not loosened, and a force for pulling up the sanitary napkin 25 is generated.

The power net constituting the fixing member 20 is formed of nylon fiber and polyurethane fiber of 100 dtex or more, and the longitudinal elongation coefficient is greater than the longitudinal elongation coefficient of the high stretching member 19. That is, the power net cloth constituting the fixing member 20 has less elasticity than the high stretching member 19. The longitudinal tensile strength of the fixing member 20 is such that the elongation coefficient is 10N to 3ON, more preferably 15N to 3ON. The mixing rate or type of fibers in the power net constituting the fixing member 20 is not limited to this, and may be appropriately selected if the above-described effects can be obtained.

As shown in FIG. 6, the sanitary napkin lifting portion 21 is disposed almost in the center of the crotch portion 13 formed by the crotch fabric 24 made of a material similar to the high stretch member 19, and the portion of the crotch portion is removed. Form. One end of the sanitary napkin lifting part 21 is sutured with the lower end of the micro-stretch member 18 provided in an almost central area of the rear part 12, and the other end of the sanitary napkin lifting part 21 is the front end ( 11) is sealed with the lower end of the fastening member 20, which is provided in an almost central region of 11). Both side ends of the fixing member 20 are closed with the crotch fabric 24 forming the crotch portion 13. The sanitary napkin lifting portion 21 extends from the vicinity of the portion in contact with the pubis to the portion around the anus, and narrows from the front end on the side of the anterior part 11 to the rear end on the side of the back part 12. The width of the sanitary napkin lifting portion 21 is 50 mm to 80 mm in the wide part, more preferably about 70 mm, 10 to 30 mm in the narrow part, and more preferably about 20 mm.

The sanitary napkin lifting portion 21 may be a combination of nylon fibers and / or polyester fibers, a combination of nylon fibers and polyurethane fibers, a combination of polyester fibers and polyurethane fibers, or similar to the micro stretch member 18, or It is formed from a knitted fabric, such as a combination of nylon fibers, polyester fibers, and polyurethane fibers, and does not include stretchable materials such as polyurethane fibers in the longitudinal direction, but has some stretch caused by changes in knitted structure, but It does not have the elasticity caused by itself. It is formed of a cloth having a longitudinal elongation coefficient smaller than the longitudinal elongation coefficient of the micro stretchable member 18. In other words, the fabric constituting the sanitary napkin lifting portion 21 is more elastic than the micro stretching member 18.

It is preferable that the elasticity of the sanitary napkin lifting part 21 is 5N-30N of elongation coefficient, More preferably, it is 10N-25N. If the elongation coefficient is less than 5N, the force for pulling up the central portion of the sanitary napkin 25 is not sufficient. When the elongation coefficient is greater than 30 N, its elasticity exceeds the elasticity of the micro stretchable member 18, so that the floating action of bringing the central portion of the sanitary napkin 25 into close contact with the body gap can hardly be performed.

As shown in Fig. 7, the sanitary napkin lifting portion 21 gradually narrows toward the middle region, from the portion sealed with the fixing member 20, which is the widest portion thereof, and then again from the middle region to the micro stretch member. It may be formed to increase toward the portion sealed in (18). In this case, the width of the sanitary napkin lifting portion 21 at the portion sealed with the micro stretchable member 18 is smaller than the width of the portion sealed with the fixing member 20.

As shown in FIG. 8, the sanitary napkin adherent fabric 16 is disposed over the inside of the crotch portion 13. The front end of the sanitary napkin sticking fabric 16 is sealed on the crotch portion 13 on the side of the front portion 11, and the rear end of the sanitary napkin sticking cloth 16 is the crotch portion 13 on the side of the rear portion 12. Suture). Sanitary napkin adherent fabric 16 is a cloth-film combination formed by suspending a waterproof cloth formed of polyurethane-laminated polyester annular stain knit and a polyester knit together around the left and right ends to protect the chucked film surface. The length L2 of the sanitary napkin adhesion cloth 16 is equal to or greater than the length L1 of the crotch portion 13, as shown in FIG. More specifically, the length L1 of the crotch portion 13 is 140 mm to 190 mm, preferably about 160 mm. The length L2 of the sanitary napkin adhesion cloth 16 is 140 mm-220 mm, Preferably it is about 200 mm.

The highly stretchable member 19 of the panty 10 is formed of a black semi-dull cloth. The waist holding portion 17, the micro stretchable member 18, and the sanitary napkin lifting portion 21 are formed of a light brown cloth. The power net constituting the fixing member 20 may be of a different color from the fabric of the highly stretchable member 19. Thus, even if the waist retaining portion 17, the micro-elastic member 18, the sanitary napkin lifting portion 21 and the fixing member 20 are different colors and the same color as the high-stretching member 19, It is desirable for these members to be visually distinguishable by changing them to have different light reflections, thereby elevating the sanitary napkin.

Next, with reference to FIGS. 10 and 11, the movement of the micro stretchable member 18, the sanitary napkin lifting portion 21, and the fixing member 20 when wearing the panty 10 according to the present invention will be described. . FIG. 10 is a cross-sectional view of the panties around the crotch portion of the body, showing how the micro stretch member, sanitary napkin lifting portion, and fastening member move around the crotch portion of the body when wearing the panties of the present invention. FIG. Reference symbol BD denotes a body, and reference symbol LG denotes a leg. 11 is a cross sectional view of a portion of the panty around the vaginal canal, showing the behavior of the portion of the panty near the vaginal canal when worn. In Fig. 11, the reference symbol I denotes the vaginal opening, and the reference symbol IT between the legs LG denotes the inside of the thigh.

At the time of wearing the panties 10, as shown in FIG. 10, by receiving the pulling force T1 caused by the micro-stretch member 18, pulling the sanitary napkin lifting portion 21 to the rear portion, the point A (fixed) The force T3 is generated so that the member and the crotch portion 13 are closed to each other and cover the gap of the body at the portion where the member and the crotch portion are in contact with the pubic bone of the body. The force T3 for pulling up the sanitary napkin lifting unit 21 acts as a force for pulling up the central portion of the sanitary napkin 25. The width of the sanitary napkin lifting portion 21 around the point A is about 70 mm and gradually widens toward the vaginal opening, perineum, and anus (to the point B, the sealed portion between the microstretch member 18 and the crotch portion 13). This narrows to a width of about 20 mm. Accordingly, the width of the sanitary napkin lifting part 21 at point A is wide, and the point A prevents the sanitary napkin lifting part 21 from moving left and right, and the center of the sanitary napkin lifting part 21 is positioned around the vaginal opening. To be fixed. If the width of the sanitary napkin lifting portion at point A is as narrow as 20 mm, the sanitary napkin lifting portion 21 may be twisted from side to side, so that the center of the sanitary napkin lifting portion 21 may not be located around the vaginal opening when worn.

As shown in FIG. 11, since the width of the sanitary napkin lifting portion 21 is narrow to about 20 mm in the vicinity of the vaginal opening, the sanitary napkin lifting portion 21 has a higher elongation coefficient than the surrounding cloth, and is elongated with a stronger force. It acts as a force (T4) to pull up the center portion of (25).

As shown in FIG. 10, the sanitary napkin lifting portion 21 is pushed backward (to the rear portion 12) by the force T1 in which the micro stretchable member 18 is pulled to the upper side of the rear portion 12. Lose. Therefore, a force that twists the sanitary napkin lifting portion 21 back occurs at point A. When the sanitary napkin lifting portion 21 is twisted backward along the point A, the force of bringing the sanitary napkin 25 generated by the sanitary napkin lifting portion 21 to the body hardly exerts an effect. That is, when the whole of the sanitary napkin lifting part 21 is twisted backward, the force which closely adheres the sanitary napkin 25 to a body does not generate | occur | produce. In order to avoid this condition, it is desirable to fix it at point A as firmly as possible. On the other hand, the fixing member 20 of the front portion 11 acts as a force for fixing the point A.

On the other hand, by closing the power net constituting the fixing member 20 to the high-stretching member 19 of the panties 10, the force T2 extending in the vertical direction generated in the front portion 11 can be reduced. . In this way, the elongation of the front portion 11 can be reduced by suturing it to the fixing member 20, so that the point A is fixed without being pulled by the micro-stretch member 18 and the sanitary napkin lifting portion 21. . The longitudinal elongation coefficient of the cloth of the power net constituting the fixing member 20 is preferably 10 N to 30 N. If the cloth is formed of an elastic fabric, the abdomen contacting the front part 11 is deformed according to the movement of the wearer. Since it is an easy part, a waist opening flows down from the upper end of the front part 11, and there exists a possibility of impairing adhesiveness.

In the present invention, the point A represents around the sutured portion between the fixing member 20 and the crotch portion, that is, the portion where the pubic bone of the body contacts, and the point B represents the micro-elastic member 18 and the crotch portion 13. The sutured portion between), ie the posterior part 12 side part than the anus, and about 150-200 mm part behind the pubic bone (on the side part of the posterior part 12).

Next, a method of measuring the elasticity of the members of the panties (microscopic stretching member, sanitary napkin lifting portion, fixing member, and high stretching member) will be described.

<Measurement of micro stretch member>

A sealed portion for suturing the rear end of the crotch portion 13 with the micro-stretch member 18 on the side of the rear portion 12 (the back portion of the crotch portion 13), and the waist opening portion 14 at this sealed portion. Chucking the chucking position at 100 mm (rectangle with 30 mm x 25 mm in the holding surface), pulling the micro-stretch member 18 at 100 mm / min with a tension tester Stretch up to 50% at speed, and measure the tensile load every 10%.

<Measurement of sanitary napkin lifting part>

The portion where the sanitary napkin lifting portion 21 is sealed with the front portion 11 and the position at which the chucking distance 150 mm from the sealing portion toward the rear portion 12 of the panty 10 is chucked (the size of the surface to be held is A 30 mm × 25 mm rectangle), tensile tester, stretches the sanitary napkin pull up to 50% at a pulling speed of 100 mm / min, and measures the tensile load each time it is stretched by 10%.

<Measurement of fixed member>

Chuck the fixing member 20 with the end of the crotch portion 13 on the side of the front portion 11 and the position at which the chucking distance 80 mm toward the waist opening 14 of the panties 10 is sewn from this sealing portion. (Rectangle with a holding surface dimension of 30 mm X 25 mm), with a tension tester, the holding member 20 is stretched to 50% at a pulling speed of 100 mm / min, and a tensile load every 10% Measure

<Measurement of the altitude stretching member>

The highly stretchable member 19 of the panty 10 is cut into dimensions of 130 mm long x 25 mm wide. Thereafter, the cut strip is held with a chuck (a rectangle having a holding surface dimension of 30 mm X 25 mm), and with a tensile tester, the highly elastic member 19 is stretched to 50% at a pulling speed of 100 mm / min, Tensile loads are measured at every 10% elongation.

Elongation coefficient is the value obtained by dividing the tensile load measured by the method described above by the corresponding elongation. For example, when the tensile load is 10N at 20% elongation, the elongation coefficient is 10N / 0.2 = 50N.

Next, FIGS. 13 and 14 show the panty 10a according to the second embodiment of the present invention and the panty 10b according to the third embodiment. Fig. 13 is a rear view showing the panties 10a according to the second embodiment, showing a state in which the panties are turned upside down so that the front and rear portions of the panties come into contact with each other. FIG. 14 is a rear view of another form of the second embodiment shown in FIG. 13. FIG. In this embodiment, the same components as those in the first embodiment are given the same reference numerals, and the description thereof is omitted.

The panty 10a of the second embodiment shown in FIG. 13 has a waterproof cloth 26 having a width of 30 to 140 mm, more preferably 80 mm, and the inner side of the panty 10a in the substantially center region of the rear part 12. This is different from the panty 10 of the first embodiment in that it extends from the crotch portion 13 to the waist holding portion 17. The waterproof cloth 26 is sealed on the crotch portion 13, the waist holding portion 17, and the micro stretchable member 18, and is coupled to the main body of the panties 10a. The left and right ends of the waterproof cloth 26 are not sewn on the rear portion 12 of the panties 10a, so that the elasticity of the panties 10a is not impaired.

This waterproof cloth 26 is sealed together around the left and right ends to protect the chucked film surface with a waterproof cloth formed of a polyurethane-laminated polyester annular stain knit fabric and a polyester knit, as in the case of the sanitary napkin adherent fabric 16. It is a cloth-film assembly formed by. The waterproof cloth 26 has elasticity in the longitudinal and lateral directions, and does not impair the elasticity of the main body of the panties 10a. .

Thus, by providing the waterproof cloth 26 in the substantially center area of the rear part 12 on the inner side of the panties 10a, when the amount of acupuncture points exceeding the absorbent capacity of the sanitary napkin is discharged, the acupuncture points overflowing from the sanitary napkin are discharged. It can be taken out with the waterproof cloth 26 to prevent leakage out of the panties 10a.

As shown in FIG. 14, the waterproof cloth 26 is not extended to the crotch portion 13 at the lower end of the waterproof cloth 26, and is almost halfway between the waist holding portion 17 and the rear portion 12. Up to a portion, may be provided to stretch. That is, the waterproof cloth 26 may be extended from the waist retaining portion 17 to the portion not covered by the sanitary napkin so that the front end of the sanitary napkin is placed on the waterproof cloth 26 when worn. The waterproof cloth 26 is sewn on the waist retaining portion 17 and the micro-elastic member 18, and at its lower end, the waterproof cloth 26 is sewn behind the highly elastic member 19b of the rear portion 12 to engage with the body of the panty 10a.
