Definitions
- the present invention relates to a panty for fitting a sanitary napkin on a crotch part and, particularly to a panty which can firmly hold the thick sanitary napkin for night use to prevent shifting out of position, is excellent in fitting property to the body, and hardly cause uncomfortable feeling for constraining of wearer's body.
- a panty is required to, certainly and firmly retain a sanitary napkin attached to the crotch part thereof, to prevent the sanitary napkin from shifting out of position at the crotch part, and in addition, and to give a comfortable feeling to the wearer by alleviating digging into a crotch portion of the body.
- a panty of this type a panty that has a section having a large tensile load bearing capacity in a center area between a front part and a back part, a crotch part positioned between the front part and the back part and joining the front part to the back part, and a pair of elastic openings for legs is disclosed (JP-2001 -522958A).
- This panty has a longitudinal stretch control member disposed in the crotch region and stretch control members which are disposed in both the front part and the back part and extend from the longitudinal stretch control member to a waist band.
- the inventors of the present invention provided a comfortable panty which can easily fit the sanitary napkin to the crotch part preventing the sanitary napkin from digging into the crotch portion (JP-A-2002-660).
- This panty includes a waist band around the waist opening part and leg bands around the leg openings, respectively, and a crotch part intended to be used for a part to attach a sanitary napkin.
- the panty is characterized in that the dimensional ratio between the center length from the crotch part to the waist opening part and the side length from the leg opening to the waist opening part, as taking that the center height length is 100, is in the range from 80 to 200 in the side height length when the dimensions are measured in a three- dimensional shaped condition as worn and an elastic lifting member is provided from the crotch part to the waist opening part in a back part.
- the sanitary napkin placed on the crotch area can be fitted tightly to the body by the stretch control member
- the stretch control member is provided as a narrow strip, a force concentrates on one linear point, and thus the panty may dig into the body in the worn condition.
- the sanitary napkin may be bent at the center to form an upward projection, and thus the top of the bent may cause uncomfortable feeling to the wearer's body.
- two elastic leg openings are formed by stitching the front part and the back part together, the stitched portion extends at the center of the crotch part so as to connect the two leg openings.
- the elastic lifting member provided on the back part extends in the longitudinal direction and generates a resilient contractive force.
- This resilient contractive force works substantially linearly along the medulla spinalis and then along the gluteal cleft and the crotch portion at the center of the back part. Therefore, a large lifting force in the for-and-aft direction is generated at the crotch part and thus the sanitary napkin on the crotch part is pressed to the ostium vagina.
- This panty has a structure such that the elastic lifting member provided on the back part extends in the longitudinal direction and thus generates an elastic lifting force for fitting the sanitary napkin to the body.
- the elastic lifting member is disposed on the back part and the front part is formed of a sufficiently elastic cloth, when the thick sanitary napkin for night use is attached to the panty, the sanitary napkin can not fitted to the hip or the crotch portion because the elastic lifting member sprawls due to the thickness and high rigidity of the sanitary napkin and thus does not adequately exercise the force to push the sanitary napkin even when the sanitary napkin is lifted by the elastic lifting member disposed on the back part to fit it to the body.
- menstrual blood may flow down along the back sides and leak from the sanitary napkin.
- the body is constricted, for example, by a tight girdle for preventing shifting out or kinking of the sanitary napkin when the wearer moves unconsciously during sleep, it may cause swelling or hernatogenous disorder due to tightness, which gives significant stress to the body.
- a panty having a structure which does not constrict the entire body, but can press and fit only the necessary portion of the sanitary napkin to the body is desirable.
- An object of the present invention is to provide a panty which can easily fit the thick sanitary napkin for night use to the crotch portion or the gluteal cleft, to prevent from shifting out of position, to prevent from digging into the crotch portion, and to provide a comfortable feeling without giving an uncomfortable feeling of constriction to the wearer.
- the present invention provides a panty which is formed by providing a highly elastic member made of a highly elasticated material, and a slightly elastic member made of a slightly elasticated material, and has a crotch part provided so as to bridge the front part with the back part.
- the slightly elastic member is provided in a center area of the back part ranging from a rear end of the crotch part to a waist hold part.
- a longitudinal elastic coefficient of the slightly elastic member is set to be larger than a longitudinal elastic coefficient of the highly elastic member covering a hip and a belly around the center area.
- a napkin lifting part stitched the slightly elastic member of the back part is provided in a middle of the crotch part, and a longitudinal elastic coefficient of which is set to be larger than a longitudinal elastic coefficient of a crotch cloth constituting the crotch part covering the crotch portion therearound.
- a panty formed by providing a highly elastic member made of a highly elasticated material and a slightly elastic member made of a slightly elasticated material comprising: a front part; a back part; a crotch part provided so as to bridge between the front part and the back part; a waist opening part provided in an upper edge of the front part and an upper edge of the back part; and a pair of leg openings provided below both side edges of the front part and both side edges of the back part, wherein a band- shaped area provided in a substantially center area of the back part from the crotch part to the waist opening part is formed of the slightly elastic member.
- the slightly elastic member allocated in the band-shape area provided from the crotch part to the waist part works to pull the crotch part connected thereto without extension. Accordingly, the sanitary napkin attached on the crotch part is pulled up and fitted to the crotch portion or the gluteal cleft of the body, whereby a gap is hardly generated between the sanitary napkin and the body and thus leakage of menstrual blood is prevented. Since the panty is made up of the highly elastic member which is highly elasticated, it is comfortable to wear without giving uncomfortable feeling of constriction all over the wearer's body as does with the girdle.
- the front part here means the front portion of the panty body which covers the belly
- the back part represents the back portion of the panty body which covers the back side of the waist.
- the panty body means the portion which covers the waist portion of the body.
- the crotch part is provided so as to bridge between the front part and the back part
- the crotch part is formed by connecting the crotch cloth to the front part and the back part by stitching or the like, not by connecting the front part directly to the back part.
- the invention provides a panty according to (1 ), wherein a longitudinal elastic coefficient of the slightly elastic member is larger than a longitudinal elastic coefficient of the highly elastic member.
- the slightly elastic member when the wearer attaches the sanitary napkin to a napkin fitting cloth and pulls the panty upward to wear, the slightly elastic member is pulled upward with the portion stitched between the crotch part and the slightly elastic member being a supporting point. Then, the force to pull up the slightly elastic member works as a force to pull the crotch part upward and as a force to suspend the sanitary napkin for night use attached to the napkin fitting cloth.
- the panty according to the present invention can easily fit the thick sanitary napkin for night use to the crotch portion or to the gluteal cleft.
- the longitudinal elastic coefficient of this slightly elastic member ranges approximately between 10N and 60N, and more preferably, between 20N and 50N.
- the elastic coefficient is smaller than 10N, a force to suspend the sanitary napkin is not sufficient and hence does not effectively work as a fqrce to suspend the sanitary napkin.
- the slightly elastic member extends too much, and thus the force exerted by the wearer does not work effectively as a force to pull up the sanitary napkin.
- the elastic coefficient larger than 60N is not preferable because a pulling up force larger than a force required for fitting the sanitary napkin is liable to be generated, and consequently, the sanitary napkin digs into the body more than necessary, which may cause uncomfortable feeling or pain.
- material which is not elastic by itself such as plastic tape or string, is not preferable because it makes the force to pull up the panty directly work as a force to pull up the sanitary napkin, and thus makes the sanitary napkin to dig excessively into the gap of the body.
- the longitudinal direction of the slightly elastic member and the longitudinal direction of the highly elastic member correspond to the direction to pull up and down the panty when wearing (Y-direction in Fig. 1 and Fig.
- the crotch portion means the portion of the body between the legs and includes portions such as the ostium vagina, the perineum, and the anal.
- the elastic coefficient means a value obtained by dividing the tensile load exerted when the members (the slightly elastic member, the highly elastic member, the napkin lifting part, and the fixing member) of the panty are pulled up and extended by a rate of extension at that time, and the larger the elastic coefficient is, the lesser the likelihood of extension becomes.
- the invention provides a panty comprising a front part; a back part; a crotch part provided so as to bridge between the front part and the back part, the crotch part being utilized for fitting a sanitary napkin; a waist opening part provided in an upper edge of the front part and an upper edge of the back part; and a pair of leg openings provided below both side edges of the front part and both side edges of the back part, wherein a napkin lifting part is provided in a middle of the crotch part from the front part to the back part, and a longitudinal elastic coefficient of the napkin lifting part is larger than a longitudinal elastic coefficient of a cloth constituting the crotch part.
- the napkin lifting part is pulled up by a force larger than a force pulling up the cloth therearound, which exerts a force to lift the center portion of the sanitary napkin attached to the crotch part (toward the crotch portion of the body).
- the elasticity of the napkin lifting part ranges from 5N to 30N in elastic coefficient, and more preferably, from 10 to 25N. When the elastic coefficient is smaller than 5N, a force to suspend the center portion of the sanitary napkin does not work effectively with respect to the pulling up force of the slightly elastic member.
- the crotch part is provided so as to bridge between the front part and the back part, it is positioned around the pubic bone and the portion backward of the anal in the worn state. Therefore, when the wearer attaches the sanitary napkin to the crotch part and wears the panty, the sanitary napkin may be stably attached to the crotch part, and thus the sanitary napkin is prevented from kinking, thereby avoiding the risk of leakage of menstrual blood.
- the waterproof cloth When providing a waterproof cioth having a waterproof property on inside of the crotch cloth constituting the crotch part, the waterproof cloth may be stitched together with the crotch cloth and the front part or with the crotch cloth and the back part along the stitched portions stitching the crotch cloth and the front part or the back part. Therefore, the number of stitching portions does not increase, and thus the uncomfortable sensation in the worn state or impair of appearance may be prevented.

- the resent invention provides a panty according to any one of (1 ) to (6), wherein the panty comprises a fixing member in a substantially center area of the front part stitched on the crotch part, the waist hold part, and the highly elastic member on an external side of the highly elastic member.
- the fixing member may control the highly elastic member to extend when the napkin lifting part is pulled toward the back part by the force carried by the slightly elastic member pulled up when the panty is wearing. Accordingly, since the portion of the napkin lifting part disposed on the side of the front part is fixed without being pulled by the influences of the napkin lifting part and the slightly elastic member, the force for pulling the slightly elastic member works directly as the force to pull up the napkin lifting part, and thus the sanitary napkin is pulled up toward the body and fitted better to the crotch portion and the gluteal cleft.
- the invention provides a panty according to (1 ), (2) or (4) to (7), wherein the slightly elastic member is formed of a material which is non-elastic in a longitudinal direction.
- the slightly elastic member since the slightly elastic member has almost no elasticity in the longitudinal direction, when the wearer attaches the sanitary napkin for night use to the napkin fitting cloth and pulls the panty up for wearing it, the pulling up force works effectively as a force to suspend the sanitary napkin.
- the slightly elastic member that can be employed here is a cloth formed of knitted fabric, such as nylon fiber or polyester fiber, including no elastic member such as polyurethane fiber in the longitudinal direction, and having slight elasticity caused by variations of knitting structure but having no elasticity generated by the property of the member.
- the invention provides a panty according to any one of (3) to (8), wherein the napkin lifting part is formed of a material which is non- elastic in the longitudinal direction.
- the napkin lifting part since the napkin lifting part has almost no elasticity in the longitudinal direction, when the wearer pulls up the panty for wearing, the napkin lifting part is pulled by the pulling up force transmitted from the slightly elastic member which is stronger than the force exerting to the cloth therearound, and such pulling up force works as a force to lift up the center portion of the sanitary napkin.
- the napkin lifting part employed here is a cloth formed of knitted fabric, such as nylon fiber or polyester fiber as it is for the slightly elastic member, including no elastic member such as polyurethane fiber in the longitudinal direction, and having slight elasticity caused by variations of knitting structure but having no elasticity generated by the property of the member.
- the invention provides a panty according to any one of (3) to (9), wherein the longitudinal elastic coefficient of the napkin lifting part is smaller than the longitudinal elastic coefficient of the slightly elastic member.
- the slightly elastic , member of the back part works to fit the sanitary napkin to the body while extending the napkin lifting part of the crotch part.
- the napkin lifting part has larger longitudinal elastic coefficient than the slightly elastic member, when the panty is pulled up, the napkin lifting part does not extend and the slightly elastic member of the back part extends, and thus can hardly exert a force to pull up the sanitary napkin toward the body.
- the invention provides a panty according to any one of (3) to (10), wherein a width of the napkin lifting part is tapered from the front part to the back part.
- the napkin lifting part is pulled toward the back part by a force to pull up the slightly elastic member and exerts a force to suspend the napkin upward, (toward the crotch portion of the body) so as to bridge the gap of the body.
- the width of the napkin lifting part is tapered gradually from the portion where the napkin lifting part is connected to the front part (the portion which comes into contact with the portion around the pubic bone), which is the widest portion, toward the portion of ostium vagina, perineum, and anal, an upward force is exerted along the centerline of the sanitary napkin attached to the crotch part with respect to the portion therearound.
- the width of the portion where the fixing member is connected to the front part is substantially the same width as the width of the crotch portion, the portion of the panty with which the portion around the pubic bone comes into contact is stabilized, and may be centered on the portion around the ostium vagina.
- the width on the side of the fixing member being narrow as the portion around the perineum or the anal is not preferable because the center of the sanitary napkin may be shifted in the worn condition, and hence shifted from the center of the ostium vagina.
- the width of this napkin lifting part may be tapered gradually from the portion where the fixing member is connected to the front part (the portion that comes into contact with the body portion around the pubic bone), which is the widest portion, toward the portion around the ostium vagina and the perineum, and then increased from the portion around the ostium vagina to the portion around the anal (but narrower than the width of the portion stitched to the fixing member).
- the invention provides a panty according to (11 ), wherein the width of the napkin lifting part ranges between 20 mm. and 60 mm.
- the width of the napkin lifting part does not assume a narrow line, the force does not concentrate on a single point. Therefore, the possibility of the napkin to dig into the body in the worn state, or of being bent and folded at the center to form an upward projection with the top of the bent giving uncomfortable feeling to the wearer's body when the napkin is attached to the napkin fitting cloth may be reduced.
- the invention provides a panty according to any one of (7) to (12), wherein the longitudinal elastic coefficient of the fixing member is larger than the elastic coefficient of the highly elastic member in the longitudinal direction.
- the fixing member at the center of the front part works as a force to fix the portion of the panty with which the portion around the pubic bone comes into contact.
- the longitudinal elastic coefficient of the fixing member is larger than the longitudinal elastic coefficient of the highly elastic member, the front part is controlled to extend in the longitudinal direction is controlled. Since the extension is controlled by the fixing member, the center area of the front part does not extend by the influence of the slightly elastic member or the napkin lifting part, and thus the portion of the panty with which the pubic bone comes into contact is fixed.
- the longitudinal elastic coefficient of the fixing member is in the range from 10N to 30N, and more preferably in the range from 15N to 25N.
- the fixing member is formed of a power net constructed of nylon fiber and polyurethane fiber.
- the longitudinal direction of the fixing member here means a direction to pull up and down the panty when wearing, that is, the direction from the crotch part to the leg opening toward the waist part
- the invention provides a panty according to any one of (1 ),
- the length of the cloth constituting the slightly elastic member from the waist hold part to the crotch part is such that the length from the center of the V-shape stitched with the waist hold part (the center point of the V-shape) to the crotch part is shorter than the left and right ends thereof. Since the amount of extension is larger at the shorter portion of the cloth than at the longer portion thereof when the cloth is extended, the portion from the center of the V-shape to the crotch part is pulled up by a force larger than the force exerted to the left and right ends thereof when the slightly elastic member is pulled upward. Therefore, the center portion does not slack and thus a force to pull up the sanitary napkin is generated.
- the invention provides a panty according to (6) to (13), wherein an upper end of the fixing member on a side of the waist opening part is stitched with the waist hold part in substantially V-shape.
- the length of the cloth constituting the fixing member extending from the waist hold part to the crotch part is such that the length of the center of the fixing member (the pointed top of the V-shape ) is shorter than the left and right ends thereof. Since the amount of extension when extended is larger at the shorter portion of the cloth than at the longer portion thereof, the center portion from of the fixing member is pulled up by a force larger than the force exerted to the left and right ends thereof when the fixing member is pulled upward,. Therefore, the center portion does not slack and thus a force to pull up the sanitary napkin is generated.
- the invention provides a panty according to any one of (1 ) to (15), wherein the crotch part comprises a napkin fitting cloth inside, front and rear ends of the napkin fitting cloth being stitched with the crotch part and side ends of the napkin fitting cloth being unstitched on the crotch part.
- the sanitary napkin fitting cloth is stitched to the crotch part only at the front and rear ends and is not completely integrated with the crotch part, that is, it is independent from the crotch part on the inside of the crotch part. Therefore, since the napkin fitting cloth does not extend in the fore-and-aft direction (in the direction toward the front part and the back part) together with the crotch part, or even when it extends, the amount of extension is very little, the sanitary napkin attached thereto may be reliably held. In addition, since it is stitched with the crotch part at the front and rear ends, it may be stitched together with the crotch cloth which constitutes the crotch part. Therefore, the number of stitching portions does not increase, and thus uncomfortable feeling in the worn state or impair of appearance may be prevented.
- the front and rear ends mean the ends of the napkin fitting cloth on the side of the front part and on the side of the back part.
- the invention provides a panty according to (16), wherein a length of the napkin fitting cloth is equivalent to or longer than a length of the crotch cloth constituting the crotch part.
- a length of the napkin fitting cloth is long enough not to extend, even when the crotch part formed of the crotch cloth of elastic fabric is extended when the wearer pulls up the panty for wearing, or even when it extends, the amount of extension is very little, and thus the sanitary napkin can be reliably held.
- the napkin lifting part is pushed toward the crotch portion and thus the sanitary napkin is pushed toward the crotch portion.
- the invention provides a panty according to (1 ), (2), or (4) to (17), wherein an elasticity gradually decreases from the highly elastic member to the slightly elastic member at a boundary between the highly elastic member and the slightly elastic member.
- the extension of the slightly elastic member gradually decreases and thus the panty can fit the wearer's body without giving uncomfortable feeling.
- the invention provides a panty according to any one of (1 ), (2) or (4) to (17), wherein an elasticity changes discontinuously from the highly elastic member to the slightly elastic member at a boundary between the highly elastic member and the slightly elastic member.
- the invention provides a panty according to any one of (1 ) to (19), wherein when the panty assumes a three-dimensional configuration, a dimensional ratio between a center height length from the crotch part to the waist opening part and the side height length which is a shortest length ranging from the leg openings to the waist opening part is set at 100 for the former and at between 80 and 200 for the latter.
- the leg bands provided at the leg openings do not tighten from the portion around the crotch portion to the side bone, but tighten the femoral regions of the wearer. Therefore, since the oblique pulling-up force generated by the leg bands does not act on the crotch part, digging into the crotch portion does not occur. In addition, since a large pulling-up force generated by the leg bands does not act on the crotch part, the sanitary napkin on the crotch part is reliably suspended upward by the slightly elastic member provided on the back part, thereby achieving better fit.
- the invention provides a panty according to any one of (1 ) to (20), wherein the slightly elastic member, the napkin lifting part, and the waist hold part exhibit different color tones or glosses from the highly elastic member.
- the slightly elastic member, the napkin lifting part, and the waist hold part are different in color or texture from the highly elastic member, they can be visually distinguished.
- the waist hold part, the slightly elastic member, and the napkin lifting part are outstanding, the wearer can easily recognize these lifting members, and can realize the effect of the lifting members easily.
- these lifting members provided at the center of the panty have different appearance from other cloth 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 can easily be aligned, and thus the center of the sanitary napkin can be fitted to the center of the crotch portion of the body adequately.
- the invention provides a panty according to any one of (1 ) to (21 ), comprising an instruction showing how to wear on the front part or on the back part.
- the wearer can control the fitting property of the sanitary napkin by viewing the instruction.
- the wearer attaches the sanitary napkin to the napkin fitting cloth on the panty via an adhesive agent or the like, and pulls up the panty by holding the upper side portion thereof when pulling up and wearing the panty to the prescribed position of the body.
- This way of wearing may also provide some degrees of adhesion to the sanitary napkin.
- desired degree of adhesion differs on an individual basis, those who want to achieve better fit can obtain adhesion of their preference by following the instruction, for example, saying that "better fitting may be achieved by pulling the portion located on the extension of the slightly elastic member at the center of the back part". In this manner, those who want to have high adhesion are guided so that they can recognize how to wear with ease.
- the invention provides a panty according to (22), wherein the instruction is provided near the waist opening part above the slightly elastic member.
- the sanitary napkin can be fitted better by pulling up the portion of the instruction.
- the slightly elastic member is pulled up by pulling the portion of the instruction further upward after wearing the panty by holding the upper side portions of the panty.
- the sanitary napkin can be pushed toward the crotch portion of the body more firmly as described above, and thus higher adhesion may be obtained.

- a highly elastic member 18 extending from the crotch part 13 to the waist hold part 17 is disposed at a center area of the back part 12.
- a part of the highly elastic member 19 which is disposed in the back part 12 forms a back side highly elastic member 19b which extends from the slightly elastic member 18 to the front part 11.
- the other part of the highly elastic member 19 which is disposed in the front part 11 forms a front side highly elastic member 19a.
- the fixing member 20 is provided, and the fixing member 20 is stitched with the highly elastic member 19.
- the highly elastic member 19 is stitched also with the crotch part 13 and the waist hold part 17 both in the front part 11 and the back part 12.
- a napkin lifting part 21 is provided in a middle of the crotch part 13 bridging the slightly elastic member 18 with the fixing member 20.
- a waist band 22 is provided along the upper side of the waist hold part 17 which is formed in the upper edges of the front part 11 and the back part 12, and leg bands 23 are provided around the leg openings 15.
- a dimensional ratio between a center height length La ranging from the crotch part 13 to the waist opening part 14 and a side height length Lb which is the shortest length ranging from the leg openings 15 to the waist opening part 14 is between 80 and 200 as taking that the center height length is 100.
- the highly elastic member 19 may be formed of a knitted fabric, such as a combination of a nylon fiber and a polyurethane fiber, a combination of a polyester fiber and a polyurethane fiber, or a combination of a nylon fiber, a polyester fiber and a polyurethane fiber. Other knitted fabric than the above-described combinations may be used as long as the elastic coefficient does not exceed 10N.
- the crotch part 13 is formed by providing a crotch cloth 24, and the crotch cloth 24 is stitched with the highly elastic member 19 on a side of the front part 11 and a side of the back part 12.
- the crotch cloth 24, similar to the highly elastic member 19, is formed of a resiliency stretchable knitted fabric such as the combination of the nylon fiber and the polyurethane fiber, the combination of the polyester fiber and the polyurethane fiber, or the combination of the nylon fiber, the polyester fiber and the polyurethane fiber.
- the waist band 22 provided along the waist opening part 14 and the leg bands 23 provided along the leg openings 15 are formed of elastic material such as elastic woven fabric of polyurethane fiber, synthetic rubber sheet, or natural rubber sheet.
- the longitudinal direction here means a direction when the waist opening part 14 and the crotch part 13 are defined to be upper and lower sides (Y-direction in Fig.
- the waist hold part 17 is formed around the waist opening part
- the waist hold part 17 is a knitted fabric whose elastic coefficient in the longitudinal direction is higher than the elastic coefficient in the lateral direction.
- the knitted fabric is the combination of the nylon fiber and the polyurethane fiber, the combination of the polyester fiber and the polyurethane fiber, or the combination of the nylon fiber, the polyester fiber and the polyurethane fiber for example.
- the waist band 22 provided around the waist opening part 14 is, for example, a polyurethane band, a natural rubber band, or a synthetic rubber band of about 10 mm and is stitched with the waist hold part 17 in an extended state.
- the waist hold part 17 functions to disperse a force to pull up the napkin lifting part 21 through the slightly elastic member 18 or the fixing member 20 and to hold the force at the waist portion, and thus it is desirable that the longitudinal extension of the waist hold part 17 is restricted so that the waist hold part 17 is held and fixed at the waist portion when the panty 10 is worn. It is desirable that a lateral elastic coefficient thereof is larger than a lateral elastic coefficient of the highly elastic member 19, because a force constricting the waist opening part 14 increases and hence the panty 10 is prevented from slipping down.
- the slightly elastic member 18 is provided in the substantially center area of the back part 12.
- the upper end of the slightly elastic member 18 is stitched with a center portion of the waist hold part 17 (the portion in the vicinity of the pointed edge of the V-shaped edge), and the lower end of the slightly elastic member 18 is stitched with an end of the crotch part 13 on the side of the back part 12 (a rear end of the crotch part 13) and both side ends of the slightly elastic member 18 are stitched with the highly elastic member 19.
- the slightly elastic member 18 extends from the waist hold part 17 to the rear end of the crotch part 13, and is tapered toward the rear end of the crotch part 13.
- the width of the narrow portion ranges from 10 mm to 30 mm, and preferably, is about 20 mm.
- the width of the wide portion where the slightly elastic member 18 is stitched with the waist hold part 17 is in the range from 30 mm to 130 mm, and preferably about 60 mm.
- the slightly elastic member 18 may be extended to
- the length of a middle area of the slightly elastic member 18 (corresponds to Lc in Fig. 1 ) is shorter than lengths of the side ends of the slightly elastic member 18 (corresponds to Ld in Fig 1 ), and the upper end of the slightly elastic member 18 and the rear end of the waist hold part 17 are stitched with each other to form a V-shaped portion having the V-shaped edge as described above. Therefore, a cloth positioned in the middle area of the slightly elastic member 18 extending from the pointed edge of the V-shaped portion to the crotch part 13 is extended more than clothes positioned in the side ends of the slightly elastic member 18 when the panty 10 is worn.
- an extension force lifting the cloth positioned in the middle area of the slightly elastic member 18 is larger than the one lifting the clothes positioned in side ends of the slightly elastic member 18.
- the slightly elastic member 18 is pulled upward, since the length of the middle area of the slightly elastic member 18 is shorter than those of the side ends of the slightly elastic member 18, the cloth positioned in the middle area is pulled up by a larger force than the force pulling up the clothes positioned in left and right ends thereof. Therefore, the center portion does not go slack and thus a force to pull up the sanitary napkin 25 is generated.
- dimensions and elastic rates were measured before and after the panty 10 is put on a doll. The dimensions and elastic rates are shown in Table 1. As shown in Table 1 , the length at the middle area of the slightly elastic member 18 is shorter before the panty 10 is worn, and the elastic rate when it is worn is large. [Table 1 ]
- Center portion (Lc) the length extending from the pointed edge of the V- shaped portion to the crotch part.
- the slightly elastic member 18 may be formed of a knitted fabric such as the combination of the nylon fiber and/or the polyester fiber, the combination of the nylon fiber and the polyurethane fiber, the combination of the polyester fiber and the polyurethane fiber, or the combination of the nylon fiber, the polyester fiber, and the polyurethane fiber.
- the cloth forming the slightly elastic member 18 has no elastic material such as polyurethane fiber in the longitudinal direction so that it has slight elasticity caused by knitting structure but has no elasticity generated by the material itself, that is, the cloth having a larger longitudinal elastic coefficient than the longitudinal elastic coefficient of the highly elastic member 19. Therefore, the slightly elastic member 18 can hardly be extended in comparison with the highly elastic member 19.
- the highly elastic member 19 covering the hip and the belly of the body therearound is formed of the cloth which is elastic longitudinally and laterally, it follows the deformation of the body caused by the movement of the wearer.
- the slightly elastic member 18 provided substantially in the center area of the back part 12 is hardly affected by the movement of the highly elastic member 19 because the longitudinal elastic coefficient thereof is larger than the elastic coefficient of the highly elastic member 19.
- the elasticity of the slightly elastic member 18 is such that the elastic coefficient is preferably in the range from 10N to 60N and, more , preferably, from 20N to 50N.
- the force to lift the sanitary napkin 25 is not sufficient when the elastic coefficient is smaller than 10N, and when the elastic coefficient is larger than 60N, the sanitary napkin 25 may dig into the gap of the body too strong.
- Fig. 11 Although the force to pull up the panty 10 directly works as a force to pull up the sanitary napkin 25 even when the slightly elastic member 18 does not extend at all, a force to pull up the sanitary napkin 25 is larger than the force required for fitting the sanitary napkin 25 which may make the is sanitary napkin 25 dig the body excessively and cause uncomfortable feeling or pain, which is not desirable.
- the slightly elastic member 18 extends excessively when the wearer pulls up the panty 10, and thus does not work effectively as a force to pull up the sanitary napkin 25.
- the elastic coefficient of the highly elastic member 19 is less than 10N, and more preferably, in the range from 2N to 3N when extended between 10 and 30%. More specifically, the tensile load exerted when the panty is extended about 20% in the worn state is in the range from 0.4 to 0.6N, so that comfortable gentle fitting along the body is achieved.
- the elastic coefficient in the worn state means the elastic coefficient obtained when the panty is put on the doll assuming medium size.
- the slightly elastic member 18 may be formed such that the extension rate is the same throughout the area, or may be formed such that the extension rate changes gradually or discontinuously to decrease from the left and right ends toward the middle area as shown in Fig. 5.
- Fig. 5 shows the slightly elastic member 18 in an enlarged manner, in which the slightly elastic member 18 is shown in a state in which the extension rate changes gradually from the left and right ends 18a toward the middle area 18b in a schematic manner.
- the relation between the extension rate and the tensile strength of the slightly elastic member 18 of the panty 10 according to the present invention is shown in Fig. 12 in comparison with the panty in the related art.
- Fig. 12 the relation between the extension rate and the tensile strength of the slightly elastic member 18 of the panty 10 according to the present invention is shown in Fig. 12 in comparison with the panty in the related art.
- the vertical axis represents the tensile load with the unit of Newton (N), and the lateral axis represents the extension rate with the unit %.
- a curve A corresponds to the panty according to the present invention and the curve B corresponds to the panty in the related art.
- the tensile load applied is P1.
- the slightly elastic member 18 of the panty 10 according to the present invention extends 30%
- the tensile load applied is P2, which means that the panty 10 of the present invention is larger tensile strength than the panty in the related art.
- the panty 10 of the present invention has- larger tensile load than that of the panty in the related art with the same extension rate.
- the tensile strength applied to the panty 10 of the present invention is P3 which is larger than the tensile strength of the panty in the related art.
- the tensile strength applied to the panty 10 of the present invention is larger, which means that the slightly elastic member 18 of the panty 10 of the present invention works effectively as the force to pull the crotch part 13. Therefore, the force to pull up the sanitary napkin 25 for night use increases, so that the sanitary napkin 25 fits better to the crotch portion of the body.
- the fixing member 20 of the panty 10 is formed of a power net, and is disposed in the substantially center area of the front part 11.
- the upper end thereof is stitched with the waist hold part 17 around the pointed edge of the V-shaped portion of the waist hold part 17, and the side edges thereof are stitched on the highly elastic member 19.
- the lower end thereof is stitched with the napkin lifting part 21 and the ⁇ 4
- the fixing member 20 is tapered from the waist hold part 17 toward the crotch part 13, and is stitched with the napkin lifting part 21 disposed in the substantially middle of the crotch part 13.
- the width of the portion where the fixing member 20 is stitched with the napkin lifting part 21 is almost the same as the width of the front end of the napkin lifting part 21 disposed in the side of the front part 11.
- the upper end stitched with the waist hold part 17 is formed into a substantially V-shape, and the width thereof is in the range from 60 mm to 150 mm, and preferably, in the range from 80 mm to 120 mm.
- the length of the center portion of the fixing member 20 (corresponds to Lc in Fig. 1 ) is shorter than those of the left and right side ends thereof (corresponds to Ld in Fig. 1 ) and the upper end of the fixing member 20 and the rear end of the waist hold part 17 are stitched to form a V-shaped portion as described above. Therefore, as in the case of the slightly elastic member 18, when the fixing member 20 is pulled upward, the center portion of the fixing member 20 is pulled up by the stronger force than the force lifting the left and right side ends thereof (See Table 1 ). Therefore, the center portion does not go slack and the force to pull up the sanitary napkin 25 is generated.
- the power net constituting the fixing member 20 is a cloth formed of nylon fabric and polyurethane fiber higher than 100 dtex, and the longitudinal elastic coefficient is larger than the longitudinal elastic coefficient of the highly elastic member 19, that is, the power net cloth constituting the fixing member 20 is less elastic than the highly elastic member 19.
- the longitudinal tensile strength of the fixing member 20 is such that the elastic coefficient is in the range from 10N to 30N, more preferably, in the range from 15N to 30N.
- the type or the mixing rate of the fiber in the power net constituting the fixing member 20 is not limited thereto, and may be selected as appropriate so that the above- described effect can be obtained.
- the napkin lifting part 21 is disposed in the substantially middle of the crotch part 13 formed by providing the crotch cloth 24 which is a similar material as of the highly elastic member 19 and forms a part of the crotch part.
- One end of the napkin lifting part 21 is stitched with the lower end of the slightly elastic member 18 provided at the substantially center area of the back part 12, and the other end of the napkin lifting part 21 is stitched with the lower end of the fixing member 20 provided at the substantially center area of the front part 11.

- the width of the napkin lifting part 21 is in the range from 50 mm to 80 mm at the wider portion, and more preferably, about 70 mm, and in the range from 10 to 30 mm at the narrower portion, and more preferably, about 20 mm.
- the napkin lifting part 21 similar to the slightly elastic member
- the nylon fiber 18, is formed of a knitted fabric such as the combination of the nylon fiber and/or the polyester fiber, the combination of the nylon fiber and he polyurethane fiber, the combination of the polyester fiber and the polyurethane fiber, or the combination of the nylon fiber, the polyester fiber, and the polyurethane fiber, and includes no elastic material such as polyurethane fiber in the longitudinal direction, and has slight elasticity caused by variations of knitting structure but has no elasticity generated by the material itself. It is formed of a cloth having a longitudinal elastic coefficient smaller than the longitudinal elastic coefficient of the slightly elastic member 18, that is, the cloth constituting the napkin lifting part 21 is more elastic than the slightly elastic member 18.
- the elasticity of the napkin lifting part 21 is preferably such that the elastic coefficient is in the range from 5N to 30N, and more preferably, in the range from 10N to 25N.
- the force to lift the center portion of the sanitary napkin 25 is not sufficient when the elastic coefficient is smaller than 5N.
- the elastic coefficient is larger than 30N, the elasticity thereof exceeds that of the slightly elastic member 18, and thus suspending action which makes the center portion of the sanitary napkin 25 fit to the gap of the body can hardly be performed.
- the napkin lifting part 21 may be formed in such a manner that the width thereof is tapered gradually from the portion stitched with the fixing member 20, which is the widest portion, toward the intermediate area, and increases again from the intermediate area toward the portion stitched to the slightly elastic member 18, as shown in Fig. 7.
- the width of the napkin lifting part 21 at the portion stitched with the slightly elastic member 18 is smaller than the width of the portion stitched with the fixing member 20.
- the napkin fitting cloth 16 is disposed over the inside of the crotch part 13.
- the front end of the napkin fitting cloth 16 is stitched on the crotch part 13 on the side of the front part 11 and the rear end of the napkin fitting cloth 16 is stitched on the crotch part 13 on the side of the back part 12.
- the napkin fitting cloth 16 is a cloth-film integration formed by stitching a waterproof cloth formed of polyurethane-laminated polyester circular dappled knit and polyester knitted fabric for protecting the laminated film surface together around the left and right ends.
- the length L2 of the napkin fitting cloth 16 is, as shown in Fig. 9, the same as the length L1 of the crotch part 13 or more.
- the length L1 of the crotch part 13 is in a range of 140 mm to 190 mm, and preferably, about 160 mm.
- the length L2 of the napkin fitting cloth 16 is in a range of 140 mm to 220 mm, and preferably, about 200 mm.
- the highly elastic member 19 of the panty 10 is formed of black semi-dull cloth.
- the waist hold part 17, the slightly elastic member 18, and the napkin lifting part 21 are formed of bright brown cloth.
- the power net constituting the fixing member 20 may be of different color from the cloth of the highly elastic member 19. In this manner, it is preferable that the waist hold part 17, the slightly elastic member 18, the napkin lifting part 21 , and the fixing member 20 are differentiated from the highly elastic member 19 in color or in light reflection by changing the amount of blended titanium oxide whether or not the colors be the same, so that these members for lifting the sanitary napkin are visually distinguishable.
- FIG. 10 is an explanatory cross-sectional view of the panty around the crotch portion of the body showing how the slightly elastic member, the napkin lifting part, and the fixing member move around the crotch portion of the body when the panty of the present invention is worn.
- Reference sign BD designates the body
- reference sign LG designates a leg.
- FIG. 11 is an explanatory lateral cross-sectional view of the portion of the panty around the ostium vagina showing the behavior of the portion of the panty in the vicinity of the ostium vagina in the worn state.
- Reference sign I in Fig. 11 designates the ostium vagina, and reference numeral IT between both legs LG designates the inside of the femurs.
- a force T3 for pulling the napkin lifting part 21 toward the back part to cover the gap of the body at a point A (a portion where the fixing member and the crotch part 13 are stitched each other, which comes into contact with the pubic bone of the body) as a supporting point is emerged by receiving a lifting force T1 caused the slightly elastic member 18. Then, the force T3 for pulling up the napkin lifting part 21 is exerted as force to pull up the center portion of the sanitary napkin 25 upward.
- the width of the napkin lifting part 21 around the point A is about 70 mm, and is tapered gradually toward the ostium vagina, the perineum, and the anal (toward a point B, which is a stitched portion between the slightly elastic member 18 and the crotch part 13) into the width of about 20 mm.
- the point A is fixed so that the napkin lifting part 21 may be prevented from moving to right or left side and the center of the napkin lifting part 21 may be around the ostium vagina.
- the napkin lifting part 21 may be shifted to right or left and hence the center thereof may not be positioned around ostium vagina in the worn state, which is not preferable.
- the width of the napkin lifting part 21 in the vicinity of the ostium vagina is as narrow as 20 mm, and the elastic coefficient of the napkin lifting part 21 is higher than the cloth therearound, it is extended by a stronger force and exerts as a force T4 for lifting the center portion of the sanitary napkin 25 upward.
- Fig. 11 since the width of the napkin lifting part 21 in the vicinity of the ostium vagina is as narrow as 20 mm, and the elastic coefficient of the napkin lifting part 21 is higher than the cloth therearound, it is extended by a stronger force and exerts as a force T4 for lifting the center portion of the sanitary napkin 25 upward.
- the napkin lifting part 21 is pulled toward rearward (the back part 12) by the force T1 caused by the slightly elastic member 18 being pulled toward the upper side of the back part 12. Therefore, a force to shift the napkin lifting part 21 toward rearward is generated at the point A.
- the force to make the sanitary napkin 25 fit to the body which is exerted by the napkin lifting part 21 , can hardly be effected.
- the force to make the sanitary napkin 25 fit to the body is not generated. In order to avoid such a state, it is preferable to fix the point A as firm as possible.
- the fixing member 20 of the front part 11 exerts the force to fix the point A.
- the force T2 generated in the front part 11 fending to extend in the vertical direction may be lessened.
- the extension of the front part 11 is lessened by stitching the fixing member 20 thereon, and thus the point A is fixed without being pulled by the slightly elastic member 18 and the napkin lifting part 21.
- the longitudinal elastic coefficient of the cloth of the power net which constitutes the fixing member 20 is preferably in a range of 10N to 30N, because if it is formed ,of non-elastic cloth, the waist opening part at the upper end of the front part 11 may slip downward since the belly with which the front part 11 comes into contact is a significantly deformable portion according to the movement of the wearer, and thus there is a risk of impairing the fitting property.
- the point A here corresponds to the stitched portion between the fixing member 20 and the crotch part 13, that is, around the portion which comes into contact with the pubic bone of the body, while the point B corresponds to the stitched portion between the slightly elastic member 18 and the crotch part 13, that is, the portion on the side of the back part 12 with respect to the anal, and the portion about 150 to 200 mm rearward (on the side of the back part 12) from the pubic bone.
- the stitched portion stitching the napkin lifting part 21 with the front part 11 and the position at the chucking distance of 150 mm from the stitched portion toward the back part 12 of the panty 10 are clamped by the chuck (the dimensions of the chucking surface is a rectangular of 35 mm X 25 mm), the napkin lifting part is extended by 50% at a pulling speed of 100 mm/min. by the tensile tester, and the tension loads are measured at every 10% of extension. ⁇ Measurement of the fixing member>
