Description

  The present invention relates to an interlabial pad that is inserted between a labia of a woman and abutted against the inner surface of the labium, and more particularly, prevents the outflow of menstrual blood regardless of the wearer's posture in the wearing state. It relates to the interlabial pad.

  Conventionally, sanitary napkins and tampons are generally used as feminine sanitary products. Here, with respect to sanitary napkins, great efforts have been made to prevent leakage of menstrual blood from gaps caused by poor adhesion to the vicinity of the vaginal opening. In addition, tampon also causes foreign object feeling and discomfort during wearing, and difficulty in wearing in the vagina due to the attributes of the article, and various measures have been taken to remove them. .

  Under such circumstances, as a sanitary product positioned between sanitary napkins and tampons, a sanitary product called an interlabial pad has recently attracted attention. The interlabial pad is worn by putting a part of the interlabial pad between female labia and contacting the inside of the labia. Therefore, the interlabial pad is more hygienic and safe to prevent menstrual blood from leaking due to its higher adhesion to the body than sanitary napkins, and to prevent menstrual blood from spreading and coming into wide contact with the body. Clean. Moreover, since it is smaller than a sanitary napkin, it is comfortable and comfortable to wear, and has a characteristic that psychological resistance when worn is lower than a tampon inserted into the vagina.

As interlabial pads having such characteristics, those having various structures have been developed. For example, in Patent Document 1 below, a front side sheet, a back side sheet, and an interlabial space in which an absorber is interposed therebetween A long convex region extending in the longitudinal direction so that a substantially central portion in the short side direction of the surface side sheet is a vertex toward the body side, and a short side of the surface side sheet as an extension of the skirt of the long convex region. An interlabial pad consisting of an extension region formed in the hand direction is disclosed.
International Publication No. WO02 / 094145 Pamphlet

  The above-mentioned interlabial pad of the above-described prior art has an extension region that extends from the labia when worn, and the extension region extends only from the bottom of the long convex region. Due to the external force due to the change, the extended region is deformed so as to cover the vulva. That is, the extension region is deformed depending on the external force, but a more specific preferable structure of the extension region has not been studied.

  FIG. 12 is a diagram showing the path of menstrual blood when the posture is constant when the conventional interlabial pad 500 as described above is worn on the labia 610 of the wearer 600. In the figure, 700 is shorts. As shown in this figure, when the posture is constant, menstrual blood is excreted at a low speed and in a small amount, and flows through the body in both outward directions. For example, when the posture is constant, such as when standing for a long time, external pressure is applied to the extension region 510, and the extension region 510 is deformed in a substantially horizontal direction so as to cover the vulva. In this case, in particular, a wearer having a body shape in which the small labia tip 620 is exposed from the large labia 630 may have a gap between the vulva region from the small labia tip 620 to the large labia 630 and the surface of the extension region 510. . Therefore, the excreted menstrual blood flows along the vulva part from the small labia tip 620 to the large labia 630 and flows out toward the shorts 700 along the arrow direction in the figure.

  On the other hand, FIG. 13 is a diagram showing the path of menstrual blood when the posture is changing. In this way, when the posture is changing, menstrual blood is excreted at a high speed and in large quantities, travels along the surface of the extension region 510, and flows more vertically. For example, when the posture is changing such as when standing up from a chair, the external pressure is released, so that the extension region 510 is deformed in the vertical direction so as to be separated from the vulva. Furthermore, since the labia are easy to open during the posture change, menstrual blood is excreted in large quantities at high speed. Therefore, the excreted menstrual blood travels along the surface of the extension region 510, and there is a high risk that the menstrual blood flows out toward the shorts 700 along the direction of the arrow in the figure.

  The present invention has been made in view of the problems as described above, and an object thereof is an interlabial pad that can prevent the outflow of bodily fluid such as menstrual blood regardless of the wearer's posture in the wearing state. The purpose is to provide.

  More specifically, the present invention provides an interlabial pad having the following configuration.

  (1) As a whole, a longitudinally long shape having a longitudinal direction and a lateral direction is formed, and an absorbent body capable of absorbing bodily fluids is provided, and a part is worn between the labia along the longitudinal direction. An interlabial pad, the interlabial pad comprising a labia pinching region sandwiched between the labia when worn, and an exposed region extending from the base of the region in the lateral direction and exposed from between the labia The interlabial pad is formed with standing portions protruding in the body direction of the wearer on at least a part of both side edges of the exposed region.

  According to the interlabial pad of the present invention, upright portions that protrude upward are formed on part of both side edges of the exposed region exposed from between the labia. For this reason, the outflow of body fluid such as menstrual blood can be prevented by changing the direction of the upright portion in accordance with the change in the external pressure. Specifically, for menstrual blood that flows outward through the body, the outflow of menstrual blood is prevented by directing the upright part toward the labial clamping area and bringing the top of the upright part into contact with the vulva it can. Further, for menstrual blood that flows along the side of the body in the exposed area of the interlabial pad, the outflow of menstrual blood can be prevented by directing the standing portion in a substantially vertical direction. Thus, according to the present invention, both menstrual blood flowing through the body and menstrual blood flowing along the body surface side of the interlabial pad can be received regardless of changes in the posture of the wearer. Can be effectively prevented.

  (2) The interlabial pad according to (1), wherein the upright portion is formed by folding the both side edges in the body direction.

  According to this aspect, the absorber is disposed in the exposed region near the upright portion formed by folding. Therefore, not only can the body fluid be received by the absorber, but also the received menstrual blood can be instantaneously absorbed by the absorber, so that even if menstrual blood is repeatedly discharged, it can be received. Moreover, since the force which tries to return from the folded shape to the original shape tends to work in the exposed region including the absorber, the tip of the standing portion and the body side surface of the exposed region can be easily separated.

  (3) The interlabial pad is interposed between the liquid-permeable front side sheet facing the wearer's body side surface, the liquid-impermeable back side sheet provided on the opposite side, and both sheets. (1) or (2) which consists of an absorber and has a joined part in which the peripheral parts of the two sheets are joined together, and the upright part is formed by folding the joined part in the body direction. ) The interlabial pad as described.

  According to this aspect, since the joining portion is composed of only two sheets and is thin, the standing portion can be easily formed. Further, since the end face of the joint portion does not directly contact the side edge of the region exposed from between the labia, even if the side edge comes into contact with the body, it is difficult to give the wearer a foreign body feeling.

  (4) The interlabial pad according to (1), wherein the upright portion is formed by providing an upright member as another member on both side edges of the exposed region.

  According to this aspect, since the shape and the like of the standing part can be selected by another standing member, the shape, height, material, and the like of the standing part can be arbitrarily set.

  (5) The interlabial pad according to (4), wherein the standing member is provided with an elastic material that expands and contracts along a longitudinal direction of the interlabial pad.

  According to this aspect, since the standing member is provided with the elastic material that expands and contracts along the longitudinal direction of the interlabial pad, it becomes easier to stand up by contraction of the elastic body. In addition, the elastic body contracts, so that a frontage (an opening portion of a recessed space formed by the upright portion and the side surface of the labia pinching region) is easily formed, and body fluid is more easily received.

  (6) The interlabial pad according to (1), wherein the upright portion is formed by providing an absorber on both side edges of the exposed region.

  According to this aspect, similarly to the above (2), the absorbent body is disposed on the standing part, so that the received menstrual blood can be absorbed instantaneously. For this reason, even if menstrual blood is repeatedly discharged, it can be received. Further, when the absorber of the convex portion is laminated as a separate member, the material of the absorber of the convex portion can be freely selected, so that the setting of the absorber material and the shape processing can be easily performed. .

  (7) The interlabial pad according to (1), wherein the upright portion is formed by folding both side edges of the exposed region.

  According to this aspect, similar to the above (2) and (6), the received menstrual blood can be instantaneously absorbed by the absorber, so that even if menstrual blood is repeatedly discharged, it can be received. Moreover, since a space is formed between the folded portions by folding, this space becomes a buffering action, and it is difficult to give a foreign object to the wearer.

  (8) The interlabial pad according to any one of (1) to (7), wherein the upright portion is provided in the longitudinal direction in the vicinity of at least a portion in contact with the wearer's vaginal opening when worn.

  According to this aspect, for example, since the upright portions are provided on both side edges of the position in contact with the vaginal opening, menstrual blood can be efficiently received near the vaginal opening where a large amount of menstrual blood is excreted at a high speed. The “part in contact with the wearer's vaginal opening” means the vicinity of the substantially central portion excluding both ends in the longitudinal direction of the interlabial pad.

  According to the present invention, the exposed region arranged at the position exposed from the labia when worn has the upright part, and the direction of the frontage by the upright part can be changed in accordance with the external pressure change. The menstrual blood flowing through the body and the menstrual blood flowing in the vertical direction through the surface of the interlabial pad can be received regardless of the change in body posture, and the outflow of menstrual blood can be prevented.

  Hereinafter, each embodiment of the present invention will be described with reference to the drawings. In the following description of the embodiment, the same constituent elements are denoted by the same reference numerals, and the description thereof is omitted or simplified.

[First Embodiment]
<Overall configuration of interlabial pad>
1 and 2 show an interlabial pad 100 according to a first embodiment of the present invention. Figure 1 is a perspective view of the interlabial pad 100 from the body side surface 12, FIG. 2 is a sectional view taken along the X ₁ -X ₂ line in FIG.

  As shown in FIGS. 1 and 2, the interlabial pad 100 has a vertically long shape as a whole, and is folded so that the sheets on the opposite body surface side 13 face each other on the central axis in the longitudinal direction. It is an interlabial pad provided with a labia nipping region 101 sandwiched between and an exposed region 102 exposed from between the labia. The body side 12 of the absorbent body 20 is covered with a liquid permeable sheet 10a (hereinafter also referred to as a front side sheet), and the non-body side 13 is covered with a liquid hardly permeable sheet 10b (hereinafter also referred to as a back side sheet). Has been. Then, as shown in FIG. 2, the peripheral edge portions 11 of both sheets are joined and folded back toward the labial clamping region 101 to form an upright portion 103.

<Labia pinching area and exposed area>
The labia pinching area sandwiched between the labia in the interlabial pad and the exposed area exposed from between the labia will be specifically shown. Although the depth of the labium varies among individuals, the average value is about 14 mm. Therefore, the labial clamping area sandwiched between the labial areas is an area within 14 mm from the vestibular floor in the vertical direction between the labial areas. is there. In addition, in the interlabial pad that changes in form before and after being installed between the labia, for example, in the interlabial pad that is folded in two with the longitudinal center line as the folding axis so that the back sheets face each other during wearing These are regions within 14 mm from the longitudinal center line in both outward directions. Further, the area that fits between the labia in the longitudinal direction is generally 55 mm as an average value of the length of the labia, 50 mm forward from the vaginal opening, and 5 mm backward. Therefore, the region that fits between the labia in the longitudinal direction is a region within 50 mm forward and 5 mm backward from the position in contact with the vaginal opening.

  The overall shape of the interlabial pad is not particularly limited as long as it is a shape that fits the labia of a woman, such as an oval shape, a heel shape, and a heel shape. The stated dimension of the outer shape is preferably 40 to 180 mm in the longitudinal direction, and more preferably 80 to 120 mm. Moreover, 20-100 mm is preferable and the width direction is preferable that it is 50-80 mm. The total dimension in the width direction shown here is the total dimension in the vertical direction in the wearing state.

<Configuration of the standing part>
As shown in FIG. 2, the peripheral edge portions 11 of both sheets are joined and folded back toward the labial clamping region 101, and joined only at the front and rear end portions 17 in the longitudinal direction shown in FIG. Thus, a recessed space is formed by the standing portion 103 and the side surface of the labia pinching region 101. In addition, although the standing part of both side edges may consist of a surface side sheet | seat and a back surface side sheet | seat like FIG. It is preferable to have a sheet on the back side because it is difficult to cause the received menstrual blood to bleed.

It explained apart the width W ₁ of the upright portion in FIG. The upright portions formed by folding are joined only at the front and rear end portions 17 in the longitudinal direction, and the upright portions 103 and the side surfaces of the labia pinching region 101 can be separated from each other, so that a frontage by the upright portions is formed. Is formed. Note that “separable” includes the case where the members are not joined but are not separated in advance. Specific spaced width _{W 1,} preferably in the range of 0～30Mm, more preferably in the range of 2 to 10 mm. Here, the measurement method of the separation width W _1, in the interlabial pad form with no pressure condition, the distance from Kagekuchibirukyo lifting region side to the tip of the standing portion in the vertical direction.

Note that the 0mm is spaced a width _{W 1,} a state in which the side surface of the standing portion 103 and Kagekuchibirukyo lifting region 101 is in contact. Spaced width W ₁ is at risk of being menstrual blood received for 30mm larger than the frontage are also larger resulting in overflow again. Even when the distance is 0 mm without being separated in advance, if the region exposed from between the labia is deformed due to a change in body posture or the like, the front side sheet and the tip of the standing portion can be separated. That is, the leading end of the upright portion is bent and a frontage is formed. That is, by changing the area exposed from between the labia, it is possible not only to change the direction of the frontage but also to change the depth of the frontage. In addition, since the standing portion 103 is formed by folding the peripheral portions extending from both side edges of the absorbent body toward the labial clamping region side, the tip of the standing portion is the body side surface of the exposed region. It will be in the state separated from.

Next, the standing width W2 of the standing part in FIG. ₂ will be described. Upright width _{W 2} is preferably in the range of 1~30mm from both side edges, and more preferably in the range of 5 to 15 mm. The method of measuring the standing width W _2, in the interlabial pad form with no pressure condition, the distance from the side edges of the interlabial pad to the tip of the standing portion. Risk of standing width W ₂ is not able to receive the large amount of menstrual blood flowing in the vertical direction down along the 1mm smaller than the surface of the interlabial pad sufficiently, the tip of 30mm larger the standing portion will fall within the interlabial This is not preferable because of its properties.

  Further, although the end face is exposed at the tip of the upright portion in FIG. 1, the end face may be prevented from being exposed at the tip by folding the tip inward in the both side edges. This makes it difficult for the wearer to feel a foreign object even when the tip of the upright part touches the skin.

  In this embodiment, since the upright part 103 is joined to the surface side sheet only by the front and rear end part 17 in the longitudinal direction, the frontage formed by the upright part 103 is provided in the entire longitudinal direction. The frontage may be provided in the entire longitudinal direction as shown in FIG. 1 or may be provided partially, but it is preferable that the frontage is provided at both side edges at a position in contact with the vaginal opening.

<Method for forming upright portion>
As a method for forming the upright portion, in particular, for joining the front and rear end portions 17, the material is bitten by an embossed pattern having irregularities, heat is applied during embossing, and the materials are heat-sealed, or joined via an adhesive. The method of doing etc. is mentioned. These methods may be performed alone or in combination. This is specifically shown below.

The embossing pattern for embossing can be employed without any particular limitation, such as a dot shape, a lattice shape, or a wave shape. As a specific example of the convex shape, the height is in the range of 0.1 to 2 mm, the interval is in the range of 0.2 to 10 mm, and the concave shape is a shape that engages with this. More specifically, two rows are arranged so that the embossed portions in each row are adjacent to each other with an area of 0.7 mm ² per stroke, the interval between the adjacent embossed portions is 1 mm, and the embossed portions in each row are alternated. The embossed pattern is a processed embossed pattern at a location 1 to 10 mm away from both side edges of the absorber. In the case of heat fusion, heat may be applied at a temperature equal to or higher than the softening point of the constituent material, and the specific means may be heat embossing or ultrasonic processing.

  Adhesives include pressure-sensitive adhesives and heat-sensitive adhesives mainly composed of rubbers such as SEBS, SBS, and SIS, and olefins such as linear low density polyethylene, polyvinyl alcohol composed of water-soluble polymers, carboxymethylcellulose, Examples thereof include water-sensitive adhesives such as gelatin or water swellable polymers such as polyvinyl acetate and sodium polyacrylate. In particular, even if body pressure is applied to the interlabial pad and the adhesive oozes out to the outer surface of the interlabial pad, it is preferable to use a heat-sensitive adhesive that does not have tackiness at that time. As a specific example, 5 to 25% by weight of SEBS, 40 to 60% by weight of alicyclic saturated hydrocarbon, 1 to 10% by weight of aromatic modified terpene, and 15 to 35% by weight of additives are melt mixed. The thing which was done is mentioned.

Adhesive coating patterns include spiral coating, control seam coating, coater coating, curtain coater coating, summit gun coating, etc. Among them, a summit gun that can make the pitch between the joint and non-joint fine. Coating is preferred. Basis weight of the adhesive in the range of 1 to 30 g / ^{m 2,} preferably in the range of 3 to 10 g / ^{m 2.} Moreover, if the adhesive is a pattern coated in a linear shape, the wire diameter is preferably in the range of 30 to 300 μm. Adhesive weight is buried between fibers and sufficient bonding strength cannot be obtained. On the other hand, if the weight is larger than 30 g / m ² or the wire diameter is larger than 300 μm, the peripheral edge becomes stiff. End up.

<Constituent material: Example of surface side sheet>
The interlabial pad surface side sheet 10a is made of a thermoplastic resin such as polyethylene, polypropylene, polyethylene terephthalate, etc., and each resin is used alone or a composite fiber of a core-sheath type, a core-sheath eccentric type, or a side-by-side type composite fiber is used. can do. Examples of the sheet formation include a single fiber or a nonwoven fabric composed of two or more kinds of fibers by point bond, through air, or the like. Among these materials, in consideration of hydrophilicity with body fluids, cellulose-based liquid hydrophilic fibers such as pulp, chemical pulp, rayon, acetate, and natural cotton may be included. Specifically, after adjusting the fiber which mixed the rayon or the acetate in the ratio of 5 to 30 weight% and the polyethylene terephthalate in the ratio of 70 to 95 weight% in the range of 20-60 g / m < ² >, fibers are entangled by hydroentanglement. A spunlace nonwoven fabric that is entangled and dried and has a thickness adjusted in the range of 0.3 to 1.0 mm is preferable. Moreover, the film which has the permeation | transmission hole which consists of thermoplastic resins, and a film may be laminated to a fiber layer, and may have a permeation hole.

<Constituent material: Example of back side sheet>
As the back side sheet 10b of the interlabial pad, a sheet that can prevent menstrual blood held by the absorber from leaking out of the interlabial pad can be used. In addition, by using a moisture-permeable material, it is possible to reduce stuffiness at the time of wearing, and to reduce discomfort at the time of wearing. Examples of the material of such a liquid-impermeable sheet include polyethylene, polypropylene, polyethylene terephthalate, polyvinyl alcohol, polylactic acid, polybutyl succinate, or nonwoven fabric, paper, and laminate materials thereof having a thickness of 15 to 60 μm. . Moreover, the air permeable film obtained by being filled with an inorganic filler and performing a extending | stretching process may be sufficient. Specifically, a film prepared mainly with a low density polyethylene resin and adjusted in a range of 15 to 30 g / m ² , and further adjusted in a range of pore diameters of 0.1 to 0.6 mm with an aperture area ratio of 10 to 30%. Breathable film. Examples of the nonwoven fabric include a spunbond nonwoven fabric, a point bond nonwoven fabric, a through-air nonwoven fabric, and the like, and these may be subjected to a water repellent treatment. Among these, an SMS (spunbond / meltblown / spunbond) nonwoven fabric including a meltblown made of ultrafine fibers and having a very small interfiber distance is preferable. In this case, the basis weight spunbond layer 5 to 15 g / ^{m 2,} the meltblown layer 1~l0g / ^{m 2,} is preferably configured in the range of spunbond layer 5 to 15 g / ^{m 2.}

  Furthermore, the front side sheet and / or the back side sheet itself to be folded may have elasticity, or another elastic sheet may be provided on both side edges. Thereby, since the force which tries to return to the original shape from the folded shape acts, the front-end | tip of an upright part and the body side surface of an exposure area | region can be spaced apart previously. Examples of the sheet having elasticity include the liquid-impervious film described above, a laminate of elastic fibers, and a foamed material having air cells.

  Specific examples of the elastic fiber include a thermoplastic material such as PE, PP, and PET, and each resin is a single or a core-sheath type, a core-sheath eccentric type, and a side-by-side type fiber. In addition, a fiber obtained by subjecting this fiber to secondary crimping by mechanical crimping or heat is preferable because it has elasticity. Furthermore, considering the feeling of wearing due to the elastic force and rigidity, it is preferable to use a product adjusted to a fiber length of 3 to 64 mm with a fineness of 0.5 to 8.8 dtex. Further, specific examples of the film include PE, PP, PET having elasticity, and a material obtained by extruding a resin such as urethane, rubber, etc. having high elasticity in a single, composite, or multilayer with a T-die or inflation. . Specific examples of the foamed material include PE, PP having elastic force, a material obtained by foaming a resin such as urethane and rubber having high elasticity, and a cellulose sponge having absorbency. The foam may be a continuous type or a stand-alone type. Furthermore, these materials can be used singly, or can be used even if they are fixed to another sheet with a multilayered adhesive or emboss.

<Constituent material: Example of absorber>
As fibers used in the absorber, pulp, chemical pulp, rayon, acetate, natural cotton, polymer absorber, fibrous polymer absorber, synthetic fiber, etc., or a mixture thereof can be used. . These fibers formed into a sheet by an airlaid method, a spunlace method, a papermaking method, a melt blown method, or the like may be subjected to embossing by passing between rollers such as needling, dot shape, lattice shape, and wave shape. The embossed area ratio is in the range of 0.1 to 60%, preferably in the range of 1 to 30%.

More specifically, 5 core-sheath eccentric type synthetic fibers of PE and PP having a fiber length of 51 mm, a fiber crimp ratio of 60%, and a fineness of 4.4 dtex with a hydrophilic oil agent of 0.2% by weight are attached. ~ 100 wt%, fiber length 51mm, fiber crimp rate 50%, hydrophilic oil agent 0.2wt% attached rayon with a fineness of 3.3dtex is opened at a mixing ratio of 95-0wt%, 50 to 1000 g / ^{m 2,} preferably in the range after collecting in the range of 100 to 800 g / ^{m 2,} which was embossed with dotted embossing pattern can be mentioned as an example. Further, the shape of these absorbers is not particularly limited as long as it is a shape that fits the labia of a woman such as an ellipse, a saddle, and a saddle, and further, slit processing may be performed to obtain flexibility. .

  Further, as an example for stably holding the interlabial pad on the finger and guiding the interlabial pad between the labia, the anti-body surface side 13 has one side portion on both sides of the longitudinal central axis. To the other side, and a mini sheet piece is provided. Thus, a finger insertion opening is formed between the mini sheet piece and the back side sheet.

<Constituent material: Example of mini sheet piece>
The examples given for the front side sheet and the back side sheet can be used, and it is preferable that the mini sheet piece is provided by an elastic sheet. Since the elastic mini-sheet piece is provided on the opposite side of the region exposed from between the labial areas, even if the external pressure is released and the region exposed from between the labial areas tends to move substantially vertically, the elastic mini-sheet The region exposed from between the labia due to the elastic repulsive force of the piece tends to return almost horizontally. For this reason, the contact between the tip of the standing part and the vulva can be maintained, and not only menstrual blood that travels on the surface of the interlabial pad but also menstrual blood that travels the body can be blocked.

  In addition, the material which comprises said interlabial pad may consist of a water-disintegrating material and a biodegradable material so that it can be washed with water.

<Action>
Next, the operation of the interlabial pad 100 will be described. Since the shape of the exposed area exposed from between the labia changes in accordance with the change in external pressure, the direction of the frontage formed by the standing portion of the exposed area exposed from between the labia also changes accordingly.

  FIG. 3 is a view showing a deformed state of the standing portion 103 of the interlabial pad 100 and a menstrual blood path in a wearing state when the posture is constant. In the figure, 300 indicates shorts. In this state, the posture is constant, and external pressure is applied to the exposed region 102 exposed from between the labia, so the exposed region 102 has a substantially horizontal shape so as to cover the vulva part 210. At this time, the frontage by the standing part 103 is directed to the labia pinching region side, and the standing part 103 and the vulva part 210 are in contact with each other at the contact point 150. As a result, it is possible to block a low-speed and small amount of menstrual blood flowing along the body and flowing along the arrow direction in the figure.

  FIG. 4 is a diagram showing a deformed state of the upright portion 103 of the interlabial pad 100 and a menstrual blood path in the wearing state when the posture is changing. When the posture is changing, the exposed area exposed from between the labia is directed almost vertically because the external pressure is released, and the front opening by the standing portion 103 faces upward. As a result, menstrual blood flowing in the vertical direction along the direction of the arrow in the drawing can be received along the surface of the exposed region.

<Modification>
FIG. 5 shows another example of the interlabial pad in the present embodiment. The interlabial pad 110 is formed by folding an exposed area 112 in which the front side of the absorbent body 20 is covered with the liquid permeable sheet 10a and the back side is covered with the liquid permeable sheet 10b along the body direction along the end of the absorbent body 20. The point which forms the standing part 113 is different from the said interlabial pad 100. In this way, when the entire absorbent body is folded back, the force to return the folded shape to the original shape is likely to work, so that the tip of the upright portion 113 and the body side surface of the exposed region can be easily separated in advance.

[Second Embodiment]
<Configuration>
6 and 7 show an interlabial pad 120 according to a second embodiment of the present invention. Figure 6 is a perspective view of the interlabial pad 120 from the body side surface 12, FIG. 7 is a sectional view taken along the X ₁ -X ₂ line in FIG. The interlabial pad 120 is different from the interlabial pad 100 according to the first embodiment in that the upright portion 123 is formed by providing the upright member 14 as a separate member on both side edges of the exposed region 122. Is different.

  The upright member 14 rises from both side edges of the exposed area 122 toward the labial clamping area side, and is then folded back into an L shape toward both side edge sides. Furthermore, the front-end | tip part of the standing member is folded down. And the linear elastic material 15 is included along the longitudinal direction at the starting point folded back to the L-shape and the tip of the standing member.

  The tip of the upright portion 123 can be further separated from the body side surface of the exposed region by the expansion / contraction force along the longitudinal direction of the elastic member 15 (force to return the stretched state to the original state). It becomes easy to form. Moreover, since the standing part 123 and the surface side sheet | seat are joined by the front-and-rear end part 17 of a longitudinal direction, the front-and-rear end part 17 of a longitudinal direction is return | folded to a body direction as shown in FIG. Thereby, the exposure area | region 122 is maintained in the substantially horizontal direction, without falling below like FIG. The shape of the upright portion 123 is not limited to an L shape as shown in FIG. 7, and is not particularly limited to a T shape, a Σ shape, or the like. Although FIG. 7 shows an example in which two elastic members 15 are provided on each side, there is no particular limitation. As the material of the elastic material 15, natural rubber, polyurethane elastic yarn or the like is generally used. In addition to the arrangement of the elastic member 15, the standing member 14 itself may have elasticity, and specifically, an elastic sheet as described above is given as an example.

  A specific example of the upright member 14 is a liquid-permeable back side sheet. In addition, as a method of manufacturing the standing portion, for example, an adhesive may be applied to the standing member 14, and the elastic material 15 in an expanded state may be joined, and then wound up by the standing member and joined to both side edges of the interlabial pad.

  Further, at least the absorber, particularly the absorber at the boundary between the labia nipping region sandwiched between the labia and the exposed region exposed from between the labia is subjected to slit processing and / or emboss processing extending intermittently or continuously in the longitudinal direction. May be. Thereby, since the absorber is bent by the tension of the elastic material on both side edges starting from the slit processing and / or embossing, the inner tip of the standing portion can be further separated from the body side surface of the exposed region. Become.

<Action>
FIG. 8 is a diagram showing a deformed state of the upright portion 123 of the interlabial pad 120 and a menstrual blood path in a wearing state when the posture is constant. Since the posture is constant and external pressure is applied to the exposed region 122 exposed from between the labia, the exposed region 122 has a substantially horizontal shape so as to cover the vulva 210. Furthermore, since the standing part 123 is provided with the elastic material 15 that can be expanded and contracted, the standing part becomes easier to stand up. Moreover, since the tip of the upright portion 123 can easily maintain contact with the vulva by folding back to the side edges, menstrual blood flowing along the body along the arrow direction can be completely blocked.

  FIG. 9 is a diagram showing a deformed state of the upright portion 123 of the interlabial pad 120 and a menstrual blood path in the wearing state when the posture is changing. When the posture is changing, the exposed area exposed from between the labia tends to go almost vertically because the external pressure is released. However, as described above, the exposed region 122 exposed from between the labia tends to maintain a substantially horizontal direction due to the elastic force of the elastic material 15 described above, so that the contact between the tip of the standing portion and the vulva is maintained, and the labia Not only menstrual blood that travels on the surface of the pad, but also menstrual blood that travels along the direction of the arrow can be blocked.

[Third Embodiment]
FIG. 10 shows a cross-sectional view of the interlabial pad 130 according to the third embodiment of the present invention. The interlabial pad 130 is mainly different from the interlabial pad 120 according to the second embodiment in that the standing portion 133 is formed by providing the absorbent body 23 on both side edges of the exposed region 132. Is different.

  The interlabial pad 130 is provided with a substantially flat absorbent body 21 above the liquid-impervious back side sheet 10b. Further, an absorbent body 22 which is bulky along the longitudinal central axis and an absorbent body 23 on both side edges are provided on the upper surface thereof, and liquid permeation along the upper surfaces of these absorbent bodies 21, 22 and 23. It covers with the surface side sheet 10a. Then, the bulky region along the central axis in the longitudinal direction forms the labia pinching region 131 sandwiched between the labia when worn, the flat region forms the exposed region 132, and the absorbers 23 on both side edges form the standing portion 133. .

  The standing portion 133 is provided at a position of 5 to 30 mm from the longitudinal central axis to both side edges, and is preferably 1 to 30 mm higher than the surface side sheet of the exposed region exposed from between the labia, and the width is in the range of 1 to 30 mm, respectively. Is preferred.

The absorbent body 23 used for the standing part may be composed of one layer or two or more layers, but the fibers used are preferably fibers that are easily compressed and easily recovered. Fiber stiffness is used as a numerical value for judging compressibility and bulk recoverability. The fiber stiffness can be generally expressed by Young's modulus (= load / strain amount). Specifically in the range of 100 to 1,500 / mm ^2, more preferably in the range of 300~1000kg / mm ^2. The fiber stiffness can also be adjusted by changing the fineness, and is specifically selected from the range of 1.1 to 8.8 dtex.

  When the absorber 23 is a separate member, the material of the absorber can be selected. Specific examples of the absorber include pulp, chemical pulp, rayon, acetate, natural cotton, polymer absorber, fibrous polymer absorber, synthetic fiber, etc., or a mixture thereof, which is bulky. It is preferable that it is difficult to lose its shape and has little chemical stimulation.

  Among them, a bulky material is preferable in order to have compressibility that does not give the wearer a feeling of foreign matter. For example, physically embossed rayon or acetate, chemical pulp cross-linked with a cross-linking agent, crimped core, or core-sheath type using the heat shrinkage rate of resin such as PE, PP, PET, etc. It is preferable to mainly use composite synthetic fibers such as types and side-by-side types. These may be mixed with ones whose molecular orientation has been enhanced by stretching at the time of spinning, and those with a different cross-sectional shape such as Y-type or C-type.

  Furthermore, it is more preferable that it is the range of the said Young's modulus, and it is a crimped fiber, since it is easy to be compressed so that it may shrink and to return to an original shape. Furthermore, an oil agent may be applied to or contained in the fibers in order to improve the slipping property between the fibers. Further, these absorbers may be subjected to slit processing in order to obtain flexibility.

[Fourth Embodiment]
FIG. 11 shows a cross-sectional view of the interlabial pad 140 according to the fourth embodiment of the present invention. The interlabial pad 140 is folded so that the back side sheets on both side edges of the exposed region 142 face each other. The point which forms the standing part 143 by joining the folded back sheet | seats with the adhesive agent in the junction part 16, and forming a convex part differs from the interlabial pad 130 which concerns on the said 3rd Embodiment. Thus, since the convex part of a both-sides edge is provided so that it may have space by folding, compressibility which does not give a wearer a foreign material feeling can be obtained, and a bulky part can be formed easily.

  The upright portions 143 may be provided at least on both side edges, but the upright portions are arranged in front and / or rear of a region that fits between the labia and flows in the front-rear direction through the front side sheet of the interlabial pad. This is preferable because menstrual blood can be received.
