Description

  The present invention relates to a garment having a body fluid absorbing pad and a crotch part.

  2. Description of the Related Art Conventionally, clothing is known in which a body fluid absorbing pad that absorbs body fluid such as menstrual blood, vaginal discharge and urine is attached to the skin side of the crotch in clothing having a crotch.

  For example, Patent Document 1 discloses shorts in which a body fluid absorbing pad is disposed on the skin side of a crotch part of a shorts body including a front body part, a back body part, and a crotch part. In this shorts, the body fluid absorption pad is attached to the shorts body by attaching the connecting cloth extending from the front and rear end edges of the pad to the entire back side surface and sewing the front and rear end edges of the connecting cloth to the shorts body. It has been. Further, the body fluid absorbing pad is disposed and attached to the skin side of the crotch so that the front edge and the rear edge thereof are substantially the same height from the bottom of the crotch.

  As this type of bodily fluid absorption pad, one in which an absorption layer is three-dimensionally arranged over a plurality of layers is known. For example, Patent Document 2 discloses a permeation cloth in which slit-like recesses are formed, and a waterproof backing that is provided on the back side of the permeation cloth and forms a bag portion by sewing a peripheral portion to the permeation cloth. There has been proposed a body fluid absorption pad having a cloth and an absorbent water retention layer that is provided in a plurality of layers inside the bag portion and absorbs and retains body fluid permeated from the recess.

  However, the conventional body fluid absorption pad has room for improvement in the following points. That is, in the conventional body fluid absorption pad, body fluids such as menstrual blood, vaginal discharge, and urine tend to accumulate on the front side of the body fluid absorption pad. Therefore, the wearer of the said garment felt wetness in the crotch part as wearing time became long, and the dry feeling was not obtained and felt unpleasant.

  In recent years, the front end edge of the crotch has been placed as low as possible in the front body by bringing the crotch behind as a whole, and the front edge of the crotch has been designed so that the front edge of the crotch is not noticeable. Clothing is increasing. In this type of clothing, the front edge of the body fluid absorbing pad is also arranged below the front body so that the attachment mark of the front edge of the body fluid absorbing pad will appear greatly on the front body and the design will not be damaged. May be attached. In this case, bodily fluids such as menstrual blood, vaginal discharge, and urine are more likely to accumulate on the front side of the bodily fluid absorption pad.

  In addition, a bodily fluid absorption pad configured to form slit-like dents on the front surface of the pad and absorb bodily fluids from the dents collects bodily fluids that can contain solids such as menstrual blood and vaginal discharge. Therefore, the dry feeling is also impaired by this. Moreover, solid content hardens and may block the slit-shaped dent.

  The present invention has been made in view of the above background, and is intended to provide a body fluid absorption pad in which body fluid does not easily accumulate on the front side of the pad even when used for a relatively long time, and a garment having a crotch portion using the pad. It is obtained.

One embodiment of the present invention is disposed on the skin side of the crotch in a garment having a crotch and is used in a state attached to the garment to absorb body fluid discharged from the crotch of the wearer of the garment. A body fluid absorption pad for
A permeation cloth that is made up of at least one sheet and permeates the body fluid from the front side surface to the back side surface, and a liquid-proof cloth that is disposed in contact with the skin side surface of the crotch part and prevents the body fluid from entering the crotch part And a multilayer laminate having a multilayer structure that is provided between the permeation cloth and the liquidproof cloth and that can absorb and retain the body fluid,
The multilayer laminate is
An upper absorbent layer that is disposed on the side of the permeation cloth and absorbs the bodily fluid on the upper side; a permeation layer that is disposed in contact with the back side surface of the upper absorbent layer and permeates the body fluid from the front side surface to the back side surface; and It is disposed in contact with the back side surface of the permeation layer, and has a bottom absorption layer that is formed at least rearward from the upper absorption layer and absorbs and holds the body fluid on the bottom side,
The upper absorbent layer is
The bodily fluid absorption pad has a notch extending rearward from an intermediate portion in the front-rear direction (Claim 1).

  Another aspect of the present invention is a garment having a crotch part, wherein the bodily fluid absorption pad is disposed on the skin side of the crotch part and attached to the garment. It is in clothing (claim 11).

  In the body fluid absorbing pad, the body fluid quickly permeates from the front side surface to the back side surface of the permeation cloth, and the body fluid hardly spreads on the pad front side surface. For this reason, the body fluid absorbing pad is easy for the wearer to feel dry. The bodily fluid absorption pad has a multilayer laminate having the specific structure as described above. Therefore, the body fluid that has penetrated into the pad flows below the upper absorbent layer while being absorbed by the upper absorbent layer. Here, the upper absorbent layer has a notch extending rearward from a midway portion in the front-rear direction. In addition, an osmotic layer that allows body fluid to permeate from the front side surface to the back side surface is disposed in contact with the back side surface of the upper absorbent layer. Therefore, the front side surface of the osmotic layer can be exposed along the notch. The portion defined by the front side surface of the permeation layer exposed by the notch and the end surface in the thickness direction of the upper absorbent layer in the notch functions as a flow path for guiding body fluid to the back side of the pad. . In other words, the rate at which body fluid penetrates into the permeation layer is faster than the rate at which body fluid is absorbed into the upper absorbent layer, so that the body fluid is absorbed and retained by the bottom absorbent layer disposed below while being drawn backward by the notch. It will be done. Therefore, even when the body fluid absorption pad is used for a relatively long time, it is difficult for body fluid to accumulate on the front side of the pad. Further, even when the body fluid absorbing pad is attached with the front end edge disposed below the front body in accordance with the arrangement of the crotch part, the body fluid absorbs the body fluid because the cutout portion facilitates the backward pulling of the body fluid. This is advantageous because it does not collect easily on the front side of the pad.

  Moreover, since the garment having the crotch part uses the body fluid absorption pad, body fluid is unlikely to accumulate on the front side of the pad even when used for a relatively long time. Therefore, even if the wearer wears the clothes for a relatively long time, the wearer does not feel wet in the crotch and can obtain a dry feeling for a long time.

It is the figure which looked at the upper absorption layer in the bodily fluid absorption pad of Example 1 from the front side. It is a figure for demonstrating arrangement | positioning with the through-hole of the three-dimensional formation layer in the bodily fluid absorption pad of Example 1, and the notch part of an upper absorption layer. 6 is a diagram schematically showing an example of another upper absorbent layer in the body fluid absorption pad of Example 1. FIG. It is explanatory drawing which shows typically the cross section of the VII-VII line of FIG. It is explanatory drawing which shows typically the cross section of the VIII-VIII line of FIG. It is a perspective view which shows typically the sanitary shorts as clothing which has a crotch part of Example 2. FIG. It is the figure which looked at the sanitary shorts as clothing which has a crotch part of Example 2 from the opening part by the side of the waist.

  The body fluid absorbing pad is mainly disposed on the skin side of the crotch part of the garment having the crotch part and is used in a state attached to the garment. That is, the bodily fluid absorption pad is not a disposable product such as a paper napkin, but when the bodily fluid is absorbed and becomes dirty, the bodily fluid is removed by washing and can be used repeatedly. In addition, the said body fluid absorption pad makes the same direction as the front side direction of the clothing which attaches this the front, and makes the same direction as the back side direction back. Further, the penetrating cloth side direction is the upper side, and the liquidproof cloth side direction is the lower side. Moreover, each member which comprises the said bodily fluid absorption pad makes the surface of the side which faces the skin side surface of the crotch part in clothing the back side surface, and makes the surface on the opposite side the front side surface.

  The crotch part in the garment having the crotch part is a part mainly arranged under the crotch part of a wearer who wears clothing such as underwear. Specific examples of clothing having a crotch part include shorts such as sanitary shorts, girdle, pants, body suits, leotards, and the like. In addition, the said wearer may be a woman or a man, and there is no restriction | limiting in particular.

  The body fluid absorbing pad is disposed with a liquid-proof cloth facing the skin side of the crotch and is attached to clothing. Specifically, for example, the body fluid absorption pad is attached with its front edge aligned with the front edge of the crotch of the garment, or with the front edge positioned behind the front edge of the crotch of the garment. Can be. The bodily fluid absorption pad includes, for example, a method of sewing the entire periphery of the bodily fluid absorption pad to the crotch portion, a method of sewing the front end portion and the rear end portion of the bodily fluid absorption pad to the crotch portion, a double-sided fastener, etc. It can be attached by, for example, a method of detachably attaching from the crotch part or the like. In particular, the method of sewing the whole periphery of the body fluid absorption pad to the crotch or the like can be worn with peace of mind without worrying about leakage of body fluid, because the body fluid absorption pad is difficult to slip and twist even if the wearer moves. There are advantages.

  The bodily fluid absorption pad is for absorbing bodily fluids discharged from the crotch of a wearer of clothing. Specific examples of the bodily fluid include menstrual menstrual blood, vaginal discharge, postpartum dew, urine, and the like. Menstrual menstrual blood, vaginal discharge, and postpartum exposure may contain solids and are more viscous than urine. It is hard to remain on the front side of the pad.

  In the bodily fluid absorption pad, the osmotic cloth can be composed of a cloth that allows body fluid to permeate from the front side surface to the back side surface over the entire surface. In this case, it is difficult for the body fluid to spread over the entire surface of the penetrating cloth, and the dry feeling of the pad front side surface can be improved. The structure / material of the permeable cloth is not particularly limited as long as it has a function of allowing body fluid to penetrate from the front side surface to the back side surface. Specifically, the permeation cloth can be configured to have a mesh-like surface, for example. In this case, there is an advantage that the wearer can easily obtain a dry feeling.

  In the body fluid absorption pad, the permeation cloth can be composed of at least one sheet. That is, the permeation cloth can be composed of a single cloth or the like, or can be composed of two or more plural cloths or the like. Moreover, when it comprises from several fabric etc., the penetration | infiltration degree of each bodily fluid can also be varied. Specifically, the osmosis cloth has, for example, a configuration including a first osmosis cloth to be brought into contact with the crotch of a wearer of clothing and a second osmosis cloth disposed in contact with the back side surface of the first osmosis cloth. It can be. Furthermore, the first permeable cloth and the second permeable cloth more specifically have, for example, a mesh-like surface, and the mesh-like surface of the first permeable cloth is more than the mesh-like surface of the second permeable cloth. Can also be configured such that the mesh becomes coarse (claim 6).

  In this case, the bodily fluid adhering to the first osmotic cloth having a coarse mesh quickly permeates downward at the adhering portion without spreading over the entire surface of the first osmotic cloth. In addition, the portion where the body fluid passes together becomes a fluid passage for the body fluid that continues to adhere to the first infiltration cloth, and prompts rapid penetration of the body fluid downward. The body fluid that has permeated the first permeation cloth further permeates the second permeation cloth having a finer mesh than the first permeation cloth. Therefore, in this case, it is advantageous for further improving the dry feeling on the front surface of the pad.

  Specifically, for example, the second permeation cloth can be configured from a cloth or the like in which one surface is a mesh surface and the other surface is a non-mesh surface. In this case, a function different from that of the first permeation cloth, such as absorption of body fluid by the non-mesh surface, can be given, which can contribute to improvement of the functionality of the pad. In this case, the mesh surface may be the front side surface, the non-mesh surface may be the back side surface, the mesh surface may be the back side surface, and the non-mesh surface may be the front side surface. The former is preferable. This is because there is an advantage that the body fluid can be easily transferred to the upper absorbent layer.

  In the bodily fluid absorption pad, the upper absorbent layer has the notch. The notch is a part of the upper absorbent layer so that the front side surface of the osmotic layer disposed below is exposed anywhere between the middle part of the upper absorbent layer in the front-rear direction and the rear edge of the upper absorbent layer. The part is a part that is cut out, and includes a notch such as a slit. The notch portion only needs to extend rearward from a middle portion in the front-rear direction of the upper absorbent layer, and the rear end portion of the notch portion and the rear end edge of the upper absorbent layer do not necessarily have to coincide with each other. . That is, the rear end part of the notch part may exist ahead of the rear end edge of the upper absorbent layer. Moreover, the notch part may be extended continuously from the middle part of the front-back direction of an upper absorption layer toward back, and may be extended discontinuously. However, from the viewpoint of ease of body fluid flow to the back side of the pad, ease of formation of the notch, etc., the rear end of the notch preferably matches the rear edge of the upper absorbent layer. Moreover, it is preferable that the notch part is continuously extended back from the middle part of the upper absorption layer in the front-back direction.

  In the body fluid absorption pad, the upper absorbent layer may have one notch or a plurality of notches. When there is a single notch, the notch can be arranged so as to be substantially along the center line in the width direction of the upper absorbent layer.

  In the bodily fluid absorption pad, the notch may be formed so that its width increases toward the rear of the upper absorbent layer. In this case, as it goes to the rear of the upper absorbent layer, more front side surfaces of the permeation layer disposed below are exposed. Therefore, in this case, it is easy to draw body fluid to the back side of the pad, which is advantageous.

  In the body fluid absorption pad, the material of the permeation layer is not particularly limited as long as the body fluid can permeate from the front side surface to the back side surface. The penetration layer can be configured to have a mesh-like surface, for example, like the above-described penetration cloth. In this case, it is easy to draw body fluid to the back side of the pad, which is advantageous. More specifically, the osmotic layer can be composed of, for example, a fabric whose one surface is a mesh surface and the other surface is a non-mesh surface. In this case, the non-mesh surface can be configured to have absorbency. In this case, the non-mesh surface may be the front surface, the mesh surface may be the back surface, the non-mesh surface may be the back surface, and the mesh surface may be the front surface. The former is preferable. This is because there is an advantage such as easier transfer of body fluid to the bottom absorption layer.

  In the bodily fluid absorption pad, the multilayer laminate may have a three-dimensionally formed layer in which a through-hole penetrating in the layer thickness direction is formed between the back side surface of the permeation cloth and the front side surface of the upper absorbent layer. (Claim 2).

  In this case, when the body fluid comes into contact with the penetrating cloth at the position corresponding to the through hole, the penetrating cloth bends downward due to the weight of the bodily fluid and passes through the penetrating cloth and falls into the through hole. Therefore, in this case, the body fluid is less likely to spread on the front side surface of the penetrating cloth and the body fluid is more easily diffused below the penetrating cloth as compared to the case where there is no solid forming layer. Therefore, in this case, the front side surface of the penetrating cloth is difficult to wet with body fluid, and the dry feeling of the pad front side surface can be improved. After the body fluid falls into the through hole, the osmotic cloth can be configured so that the downward deflection is recovered depending on the body temperature of the wearer, the characteristics of the material, and the like, and returns to a slightly flat state. From the viewpoint of enhancing the above effect, the through hole is preferably arranged at a position corresponding to a body fluid discharge port (for example, a vaginal opening, a urethral opening, etc.) in the wearer's crotch portion in the wearing state.

  In the bodily fluid absorption pad, the through hole and the front end portion (tip portion) of the notch portion can be arranged to overlap each other in plan view.

  In this case, since the bodily fluid that has flowed into the through hole comes into contact with the front end portion of the notch, it is easy to efficiently guide the bodily fluid to the notch. The shape of the through hole is not particularly limited. The shape of the through hole is, for example, a substantially circular shape, a substantially oval shape, a rounded rectangular shape (consisting of two parallel lines of equal length and two arcs), a substantially oval shape, a substantially bowl shape, or a rectangular shape. And a polygon such as a quadrangle such as a square, a trapezoid, etc., and a substantially rhombus (including two pairs in which diagonal lines are orthogonal and adjacent sides are equal). When the shape of the through hole is a shape including a straight line at least in part, for example, when sewing around the through hole, it is easy to position a sewing device such as a sewing machine, which can contribute to productivity improvement, etc. There are advantages.

  In addition, a solid formation layer can be comprised from 1 layer or 2 layers or more. Moreover, the three-dimensionally formed layer can have an absorption function for absorbing body fluid, for example. In this case, it becomes easy to suppress the backflow of body fluid from the bottom to the top. In this case, since the three-dimensionally formed layer can also absorb body fluid, it can contribute to an increase in absorption capacity on the upper side of the pad.

  The bodily fluid absorption pad, when the multilayer laminate has a three-dimensionally formed layer, stitches the permeable cloth and the multilayer laminate along the outer periphery of the through hole and includes a portion exposed to the skin side surface of the permeable cloth. (Claim 4).

  In this case, since the sewing thread is exposed along the outer periphery of the through hole on the front side surface of the penetrating cloth, the design of the body fluid absorbing pad can be improved by the exposed sewing thread. Furthermore, in this case, even if the wearer takes various postures, the permeation cloth and each layer of the multilayer laminate are not easily displaced from each other by the sewing thread along the outer periphery of the through hole, which corresponds to the movement of the wearer of the garment. There are advantages such as easier. In addition, there is an advantage that the shape is easily maintained even after washing.

  In the body fluid absorption pad, the bottom absorption layer can be composed of a single layer or a plurality of layers.

  When the bottom absorbent layer is composed of a single layer, it is thin, absorbent, and can be a soft body fluid absorbent pad. Further, when the bottom absorption layer is composed of a plurality of layers, the absorption capacity of the bottom absorption layer can be increased or decreased by increasing or decreasing the number of layers constituting the bottom absorption layer. Therefore, in this case, it becomes easy to obtain a body fluid absorption pad having an absorption capacity corresponding to the total amount of body fluid to be absorbed. In addition, the flexibility of the body fluid absorbing pad can be adjusted by increasing or decreasing the number of layers constituting the bottom absorbent layer or by appropriately changing the outer shape and size of each layer. Therefore, in this case, it becomes easy to obtain a bodily fluid absorption pad that easily fits the wearer's crotch.

  In the bodily fluid absorption pad, both side edges of the multilayer laminate can be disposed inside the both side edges of the permeation cloth and the liquid-proof cloth.

  In this case, even if the wearer takes various postures, the body fluid absorbed and held in the multilayer laminate is difficult to leak out from both side edges of the pad (it is difficult to leak sideways).

  In the body fluid absorption pad, the multilayer laminate can be configured to be sewn to the back side surface of the permeation cloth.

  In this case, even if the wearer takes various postures, the multilayer laminate is unlikely to be displaced, so that the absorption and retention of body fluid can be ensured. Moreover, since it is not necessary to make a needle hole etc. in a liquid-proof cloth for attachment of a multilayer laminated body, liquid-proof reliability can be improved.

  In the body fluid absorption pad, the liquid-proof cloth is formed larger than the permeable cloth and the multilayer laminate, and the outer peripheral edges of the permeable cloth and the outer peripheral edge of the liquid-proof cloth are joined together. It can be set as the structure which has a water-repellent water-repellent cloth (Claim 10).

  In this case, even if the wearer takes various postures and the body fluid absorbed and retained in the multilayer laminate leaks from the outer peripheral edge of the multilayer laminate, Can stay inside the fabric. Therefore, in this case, body fluid is more difficult to leak from the outer peripheral edge of the pad.

  The water repellent cloth can be composed of a smooth cloth made of a material such as polyester. Since the water-repellent smooth fabric has water repellency and is soft and excellent in touch, it can be suitably used as a water-repellent fabric. The water-repellent cloth and the permeable cloth can be connected to each other by sewing the inner edge of the water-repellent cloth and the outer peripheral edge of the permeable cloth. Further, the water-repellent cloth and the liquid-proof cloth can be connected to each other by sewing the outer edge of the water-repellent cloth and the outer peripheral edge of the liquid-proof cloth. At this time, the water-repellent cloth and the liquid-proof cloth can be connected to each other by a sewing thread when attaching the body fluid absorbing pad to the crotch part of the garment. The bodily fluid absorption pad may further include a piping that encloses the outer edge of the water-repellent cloth and the outer peripheral edge of the liquid-proof cloth. In this case, there is an advantage that the appearance of the body fluid absorption pad alone is improved.

  In the garment having the crotch part, the body fluid absorption pad may be configured such that the entire periphery thereof is sewn to the crotch part (claim 12).

  In this case, the entire circumference of the body fluid absorption pad is sewn to the crotch, so the body fluid absorption pad is difficult to slip and twist even if the wearer moves, so wear it without worrying about body fluid leaks. There are advantages you can do.

  The garment having the crotch part is a state in which the front and rear edges of the body fluid absorption pad are attached to the garment by sewing or the like, and the both side edges of the pad are released from the garment without being attached to the garment by sewing or the like. It is also possible. In this case, when a disposable bladed napkin or the like is used in combination, the blade portion of the napkin can be sandwiched between the body fluid absorbing pad and the crotch portion and stopped as necessary. In the garment, another liquid proof cloth may be further arranged between the liquid proof cloth of the body fluid absorbing pad and the crotch part of the garment. In this case, it becomes easy to reliably prevent body fluid from adhering to the crotch part of the clothing.

  The garment having the crotch part may be sanitary shorts (claim 13).

  In this case, sanitary shorts that are gentle to the wearer's skin can be obtained due to the soft touch of the body fluid absorbent pad and the excellent dry feeling. In this case, sanitary shorts that can be worn directly without using disposable paper napkins are obtained. In this case, since the amount of disposable paper napkins can be reduced, dust is reduced and sanitary shorts friendly to the global environment can be obtained.

Hereinafter, the garment which has a bodily fluid absorption pad and a crotch part of an Example is demonstrated using drawing.
Example 1
The bodily fluid absorption pad of Example 1 is shown in FIGS. As shown in FIGS. 9 and 10 to be described later, the body fluid absorbing pad 1 is disposed on the skin side of the crotch 61 in the garment 6 having the crotch 61 and is used in a state attached to the garment 6. In this example, specifically, the body fluid absorption pad 1 is disposed with the back side of the pad facing the skin side surface of the crotch 61 in the sanitary shorts 60, and the entire periphery thereof is sewn to the crotch 61. Used in state. At this time, the body fluid absorbing pad 1 is sewn with its front end edge aligned with the front end edge of the crotch 61 of the garment 6. The body fluid absorbing pad 1 is for absorbing body fluid discharged from the crotch of the wearer of the garment 6. The body fluid to be absorbed in this example is mainly menstrual blood or vaginal discharge.

  The body fluid absorption pad 1 is composed of at least one sheet, and is disposed in contact with the skin side surface of the crotch part 61 and the permeation cloth 2 that permeates the body fluid from the front side surface to the back side surface. A liquid-proof cloth 3 to be prevented, and a multilayer laminate 4 having a multilayer structure that is provided between the permeation cloth 2 and the liquid-proof cloth 3 and that can absorb and retain body fluids.

  The multilayer laminate 4 is disposed on the side of the permeable cloth 2 and is disposed in contact with the upper absorbent layer 41 that absorbs bodily fluids on the upper side and the back side surface of the upper absorbent layer 41, and permeates the body fluid from the front side surface to the back side surface. It has a permeation layer 42 and a bottom absorption layer 43 that is arranged in contact with the back side surface of the permeation layer 42 and is formed at least rearward of the upper absorption layer 41 and absorbs and retains body fluids on the bottom side. . And the upper absorption layer 41 has the notch part 410 extended toward the back from the intermediate part of the front-back direction. Hereinafter, the bodily fluid absorption pad 1 of this example will be described in detail.

  The permeation cloth 2 constitutes the pad front side surface of the body fluid absorption pad 1. The osmotic cloth 2 is formed smaller in size than the crotch part 61 of the garment 6 to which the body fluid absorbing pad 1 of this example is applied. More specifically, the permeation cloth 2 is formed so that the outer peripheral edge thereof is positioned about 15 to 30 mm inside the outer peripheral edge of the crotch portion 61. In this example, the width of the rear side compared to the front side Is wide and has a substantially divergent shape as a whole. Both side edges of the osmotic cloth 2 are formed to be curved so as to be disposed inward at a certain distance from both side edges of the crotch part 61 of the garment 6. The front end edge of the osmotic cloth 2 is formed to be curved forward and convex. The rear end edge of the osmotic cloth 2 is formed to be curved rearward.

  Specifically, the permeable cloth 2 includes a first permeable cloth 21 that is brought into contact with the crotch portion of the wearer of the garment 6 and a second permeable cloth 22 that is disposed in contact with the back side surface of the first permeable cloth 21. It consists of two sheets. In this example, the 1st penetration cloth 21 is constituted from the cloth which has a mesh-like surface. On the other hand, the 2nd penetration cloth 22 is constituted from the cloth whose one side is a mesh-like surface, and the other side is a non-mesh surface. In this example, the second osmotic cloth 22 has a mesh-like surface on the front side and a non-mesh-like surface on the back side so that body fluid can smoothly penetrate from the first permeable cloth 21 to the second permeable cloth 22. Use it so that it becomes a surface. In addition, the non-mesh surface that constitutes a part of the second permeable cloth 22 can absorb body fluid slightly. The mesh surface of the first permeable cloth 21 is set to be coarser than the mesh surface of the second permeable cloth 22. Specifically, the first permeation cloth 21 has about 9 stitches per 1 inch in the horizontal direction and about 8 stitches per 1 inch length, and the second permeation fabric 22 has 18 stitches per 1 inch width and 6.5 per 1 inch length. It is about eyes. Specifically, the material of the first osmosis cloth 21 is 100% polypropylene. Specifically, the material of the second permeable cloth 22 is a mixture of cotton and polyester, and the mixing ratio of cotton and polyester is about 60% cotton and about 40% polyester. The osmotic cloth 2 configured as described above can infiltrate body fluid from the front side surface to the back side surface over the entire surface.

  The liquidproof cloth 3 constitutes the pad back side surface of the body fluid absorbing pad 1 of this example. The liquidproof cloth 3 is formed to have substantially the same outer shape and size as the crotch part 61 of the garment 6 to which the body fluid absorbing pad 1 of this example is applied. That is, the liquid-proof cloth 3 is formed to be larger than the penetrating cloth 2. Therefore, in this example, in the state where the permeable cloth 2 and the liquid proof cloth 3 are overlapped at an appropriate position, the outer peripheral edge (front edge, rear edge, both side edges) of the liquid proof cloth 3 is the permeable cloth 2. It is comprised so that it may arrange | position outside the outer periphery (a front-end edge, a rear-end edge, both-sides edge).

  The liquidproof cloth 3 is made of a cloth that does not allow body fluid to permeate. As the fabric, for example, a fabric in which at least one surface of the base fabric is liquidproofed with a polymer that does not allow body fluid to permeate can be used. In addition, when only one surface of the base fabric is liquid-proofed, the liquid-proofed surface is preferably a front side surface from the viewpoint of improving liquid-proof properties. In this example, specifically, a fabric in which one side of a base fabric made of 100% polyester is liquidproofed with polyurethane is used. In this example, from the viewpoint of ensuring liquidproofness, the liquidproofed surface is the front side surface, and the non-liquidproofed surface is the backside surface.

  In this example, the outer peripheral edge of the penetrating cloth 2 and the outer peripheral edge of the liquid-proof cloth 3 are connected by a water-repellent water-repellent cloth 5. Specifically, the water repellent cloth 5 includes a front end edge water repellent cloth 51, a rear end edge water repellent cloth 52, a left side edge water repellent cloth 53, and a right side edge water repellent cloth 54. The water repellent cloth 5 is a smooth cloth made of 100% polyester.

  The body fluid absorbing pad 1 of this example is formed into a bag shape as a result of the permeation cloth 2 and the liquid proof cloth 3 having different sizes being joined together by the water repellent cloth 5, and the multilayer laminate 4 is disposed in the bag. Has been. The body fluid absorbing pad 1 is formed by enclosing the outer peripheral edges of the permeation cloth 2 and the liquid proof cloth 3 by piping (not shown) in consideration of the amount of body fluid to be absorbed without using the water repellent cloth 5. It is also possible to constitute a bag shape as a whole.

  The multilayer laminate 4 is composed of a plurality of functional layers, and can absorb and hold body fluids as a whole. In this example, as shown in FIG. 3, the multilayer laminate 4 includes a three-dimensional formation layer 40, an upper absorption layer 41, an infiltration layer 42, and a bottom absorption layer 43 in order from the infiltration cloth 2 side downward. Are stacked in this order. In this example, the multilayer laminated body 4 has shown the example which has the three-dimensional formation layer 40 between the back side surface of the permeable cloth 2, and the front side surface of the upper absorption layer 41. FIG. The three-dimensionally formed layer 40 is additionally provided to suppress spreading of body fluid on the front side surface of the permeable cloth 2 and to promptly diffuse body fluid below the permeable cloth 2, and is omitted. It is also possible. Hereinafter, the multilayer laminate 4 will be described in order from the penetrating cloth 2 side.

  As described above, in this example, the three-dimensionally formed layer 40 has the through hole 400 that penetrates in the layer thickness direction. Specifically, the through-hole 400 is disposed so as to be at a position substantially corresponding to the vaginal opening in the crotch portion of the average wearer when the body fluid absorption pad 1 is worn. When viewed from the whole body fluid absorbing pad 1, the center of the through hole 400 is disposed slightly forward of the center in the front-rear direction of the center line that bisects the pad width direction. Further, the shape of the through hole 400 in this example is a substantially elliptical shape having a length of about 50 mm in the front-rear direction of the pad and a length of about 30 mm in the pad width direction. The through hole 400 is formed by punching with a mold, but is not limited thereto, and can be formed by various methods. The through hole 400 has a shape and a size that allow the permeation cloth 2 to bend downward due to the weight of the body fluid when the body fluid is placed on the permeation cloth 2 located above the through hole 400. Is formed. Therefore, the through hole 400 of this example is different from the narrow slit hole found in the prior art. The penetrating cloth 2 can be configured to return to a substantially flat state by passing through the penetrating cloth 2 and dropping body fluid into the through hole 400 and then drying.

  The three-dimensionally formed layer 40 is formed so that the length in the pad front-rear direction and the pad width direction is smaller than that of the permeable cloth 2. Specifically, both edge sides of the three-dimensionally formed layer 40 are formed to be curved so as to be disposed inward at a certain distance from both side edges of the crotch portion 61 of the garment 6. Specifically, both the front edge and the rear edge of the three-dimensionally formed layer 40 are formed substantially parallel to the pad width direction. The three-dimensionally formed layer 40 is made of a fabric that can absorb and retain body fluid. Therefore, the three-dimensionally formed layer 40 not only promotes the downward deflection of the osmotic cloth 2, but also suppresses the backflow of body fluid from the bottom to the top, and can complement the absorption function of the upper absorbent layer 41 described later. It is said that. Specifically, the material of the three-dimensional formation layer 40 is a mixture of cupra, nylon, and acrylic. These mixing ratios are about 46% of cupra, about 27% of nylon, and about 27% of acrylic.

  The upper absorbent layer 41 is formed so that the length in the pad front-rear direction and the pad width direction is smaller than that of the permeable cloth 2. Specifically, both edge sides of the upper absorbent layer 41 are formed to be curved so as to be disposed inward at a certain distance from both side edges of the crotch portion 61 of the garment 6. Specifically, the front edge and the rear edge of the upper absorbent layer 41 are both formed substantially parallel to the pad width direction. In the present example, the three-dimensionally formed layer 40 described above is formed to have substantially the same outer shape and size as the upper absorbent layer 41. Moreover, in this example, the upper absorption layer 41 is comprised from the fabric which can absorb a bodily fluid. Specifically, the material of the upper absorbent layer 41 is a mixture of cupra, nylon and acrylic. These mixing ratios are about 46% of cupra, about 27% of nylon, and about 27% of acrylic.

  Here, the upper absorbent layer 41 has a notch 410 extending rearward from a midway portion in the front-rear direction. In this example, as shown in FIGS. 3 and 4, the number of the notches 410 is one, and is arranged so as to be substantially along the center line in the width direction of the upper absorbent layer 41. Further, the notch portion 410 continuously extends rearward from an intermediate portion in the front-rear direction of the upper absorbent layer 41, and is formed so that the width thereof becomes wider toward the rear of the upper absorbent layer 41. . Therefore, the notch 410 can gradually expose more front side surfaces of the permeation layer 42 disposed below as it goes rearward of the upper absorbent layer 41. In this example, as shown in FIG. 5, the through hole 400 of the three-dimensional formation layer 40 and the front end of the notch 410 are arranged so as to overlap each other in plan view. In other words, the front end portion of the notch portion 410 is disposed so as to overlap with a projection surface obtained by projecting the through hole 400 of the three-dimensional formation layer 40 onto the upper absorption layer 41. On the other hand, the rear end of the notch 410 is made to coincide with the rear edge of the upper absorbent layer 41 in this example. The length of the notch 410 in the front-rear direction of the pad is about 60 mm, and the length in the pad width direction at the rearmost end of the notch 410 is about 8 mm.

  In this example, as described above, the cutout portion 410 is formed in a substantially isosceles triangle shape with a part on the rear edge of the upper absorbent layer 41 as a base, but formed in another shape. May be. In FIG. 6, an example of the modification of the notch part 410 is shown. The notch 410a in FIG. 6A illustrates the case where the rear edge exists ahead of the rear edge of the upper absorbent layer 41. The notch portion 410b in FIG. 6B illustrates a case where the width of the upper absorbent layer 41 is formed to be substantially constant from the front to the rear. The notch portion 410c in FIG. 6C exemplifies a case where it is formed in a substantially long hole shape that is long in the front-rear direction. The notches 410d and 410e in FIGS. 6 (d) and 6 (e) exemplify a case where the notches 410d and 410e are composed of a plurality of notches extending continuously rearward. The notch portion 410f in FIG. 6 (f) is an example of a case where it extends rearward discontinuously.

  The permeation layer 42 is formed so that the length in the front-rear direction of the pad and the length in the pad width direction are smaller than those of the permeation cloth 2. The garment 6 is formed to be curved so as to be arranged inwardly at a certain distance from both side edges of the crotch part 61. Specifically, the front edge and the rear edge of the osmotic layer 42 are both formed substantially parallel to the pad width direction. In this example, the permeation layer 42 is formed to have substantially the same outer shape and size as the three-dimensional formation layer 40 and the upper absorption layer 41. The osmotic layer 42 is made of a fabric that can permeate body fluid from the front side surface to the back side surface. Specifically, the osmotic layer 42 is made of a fabric made of the same material as that of the second osmotic cloth 22 in the osmotic cloth 2. However, in this example, the non-mesh surface of the fabric is used as the front side surface and the mesh surface is used as the back side surface from the viewpoint of encouraging the body fluid to be drawn downward.

  Although the bottom absorption layer 43 can be composed of one layer, in this example, the bottom absorption layer 43 is composed of a plurality of layers. Specifically, the bottom absorbent layer 43 includes a permeation layer side absorbent layer 433 disposed in contact with the back side surface of the permeation layer 42 and a liquidproof cloth side absorbent layer disposed in contact with the front side surface of the liquidproof cloth 3. 434.

  The permeation layer side absorption layer 433 and the liquidproof cloth side absorption layer 434 are formed larger in the front-rear direction than the upper absorption layer 41. More specifically, the permeation layer side absorbent layer 433 and the liquidproof cloth side absorbent layer 434 are wider on the rear side than the front side, and are generally widened toward the rear as a whole. Both side edges of the osmotic layer side absorbent layer 433 and the liquidproof cloth side absorbent layer 434 are formed so as to be positioned about 5 mm inside both side edges of the permeable cloth 2, and both side edges of the crotch part 61 of the garment 6. It is formed to be curved so as to be disposed inward at a predetermined distance from the center. The permeation layer side absorption layer 433 and the liquidproof cloth side absorption layer 434 are formed so that the respective side edges thereof substantially coincide with each other when the solid formation layer 40, the upper absorption layer 41, and the permeation layer 42 are overlapped. Has been. Further, the front end edges of the osmotic layer side absorbent layer 433 and the liquidproof cloth side absorbent layer 434 are both curved so as to be convex forward. The rear end edges of the osmotic layer-side absorbent layer 433 and the liquid-proof cloth-side absorbent layer 434 are both curved so as to be convex rearward. However, the permeation layer side absorbent layer 433 is arranged so that the rear edge thereof is disposed at a position approximately 16 mm ahead of the rear end edge of the liquidproof cloth side absorbent layer 434. It is formed smaller than. The front end edges of the permeation layer side absorbent layer 433 and the liquidproof cloth side absorbent layer 434 are formed so as to substantially coincide with the front end edge of the permeation cloth 2 when overlapped with the permeation cloth 2. Further, the rear end edge of the liquid-proof cloth-side absorbent layer 434 is formed so as to substantially coincide with the rear end edge of the permeation cloth 2 when overlapped with the permeation cloth 2.

  The bottom part absorption layer 43 is comprised from the fabric which can absorb and hold | maintain a bodily fluid. In this example, the bottom absorption layer 43 has a larger body fluid absorption capacity than the upper absorption layer 41, as can be seen from the fact that the bottom absorption layer 43 is formed larger than the upper absorption layer 41 and is composed of a plurality of layers. Is set. Therefore, most of the body fluid that has flowed in when the wearer wears for a long time is mainly absorbed and retained by the bottom absorbent layer 43. In this example, the bottom absorbent layer 43 is made of the same material as the upper absorbent layer 41.

  In this example, both side edges of the multilayer laminate 4 having the above-described configuration are disposed on the inner side than both side edges of the permeable cloth 2 and the liquid-proof cloth 3. The multilayer laminate 4 is sewn to the back side surface of the permeable cloth 2. In this example, body fluid absorption pad 1 has sewing thread L1 for sewing permeation cloth 2 and multilayer laminate 4 along the outer periphery of through hole 400. The sewing thread L1 is disposed at a position about 3 mm outward from the edge of the through hole 400 and includes a portion exposed on the front side surface of the permeable cloth 2. Therefore, as shown in FIG. 1, the bodily fluid absorption pad 1 of the present example has an annular shape formed by a sewing thread L1 formed in a substantially elliptical shape corresponding to the outer peripheral shape of the through hole 400 on the skin surface side of the penetrating cloth 2. The part is visible.

  Next, an example of the manufacturing method of the bodily fluid absorption pad 1 of this example is demonstrated. Here, a method of sequentially laminating the members constituting the body fluid absorption pad 1 of this example by sewing will be described. The sewing location, the sewing procedure, the sewing method, and the like are not limited by the following description, and can be appropriately optimized in consideration of productivity and the like.

  First, each member which comprises the bodily fluid absorption pad 1 of this example is prepared. Next, the back side surface of the upper absorbent layer 41 and the front side surface of the osmotic layer 42 are overlapped and sewn to configure the laminate A. In this example, specifically, the back side surface of the upper absorbent layer 41 and the front side surface of the osmotic layer 42 are overlapped, and the periphery of the notch 410 is sewn using a sewing thread L2 such as a resinon thread. (However, it is around the hypotenuse of the substantially isosceles triangular notch 410 and excluding the rear edge of the notch 410), and the laminate A is formed.

  Next, the back side surface of the three-dimensionally formed layer 40 is superimposed on the front side surface of the upper absorbent layer 41 in the obtained laminate A, and a part of the bottom absorbent layer 43 is configured on the back side surface of the permeation layer 42 in the laminate A. The front side surface of the permeation layer side absorption layer 433 is overlapped. In addition, the laminated body A and the osmotic layer side absorption layer 433 are overlaid so that the osmotic layer side absorption layer 433 protrudes from the front and rear of the laminated body A in a state in which both are laminated. And in this example, the front end edge of the laminated body A is sewn by the main sewing using the sewing thread | yarn L3, such as a resinon thread | yarn, and the laminated body B is comprised.

  Next, the front side surface of the liquid-proof cloth side absorbent layer 434 constituting the remainder of the bottom absorbent layer 43 is superimposed on the back side surface of the permeation layer side absorbent layer 433 in the obtained laminate B. In addition, the laminated body B and the liquid-proof cloth side absorption layer 434 are overlaid so that the liquid-proof cloth side absorption layer 434 protrudes from the back of the laminated body B in a state where both are overlaid. In this example, the laminated body C is formed by sewing the rear end edge of the laminated body B by main sewing using a sewing thread L4 such as a resinon thread.

  Next, the second permeable cloth 22 and the first permeable cloth 21 constituting the permeable cloth 2 are laminated in this order on the front side surface of the three-dimensionally formed layer 40 in the obtained laminate C. And in this example, about 8 mm inside each side edge of the laminated body C is sewn by the main sewing using the sewing thread L5, such as a resinon thread, and the laminated body D is comprised.

  Next, the laminated body E is formed by sewing by sewing using a sewing thread L1 such as a regiron thread along the outer periphery of the through hole 400 of the three-dimensionally formed layer 40 in the obtained laminated body D. The sewing position at this time is about 3 mm outward from the peripheral edge of the through hole 400.

  Next, the left side edge water-repellent cloth 53 is sewn to the left side edge and the right side edge water-repellent cloth 54 is sewn to the right side edge by using the sewing threads L6 and L7 such as RESIRON yarns in the obtained laminate E, and the layers are laminated. The body F is comprised. In this case, as shown in FIG. 8, the inner edges of the left-side edge water-repellent cloth 53 and the right-side edge water-repellent cloth 54 are bent downward, and the bent pieces and the permeation cloth 2 are joined together. This can be performed by connecting the sewing threads LL6 and L7. When such joining is performed, the sewing thread L6, L7 can be configured not to be exposed on the skin side of the produced body fluid absorption pad 1.

  Next, the front end edge water-repellent cloth 51 is sewn to the front end edge in the obtained laminate F, and the rear end edge water-repellent cloth 52 is sewn to the rear end edge by sewing using the sewing threads L8 and L9 such as resinon threads. The laminated body G is comprised. In this case, as shown in FIG. 7, the inner edge of the front end edge water-repellent cloth 51 is bent downward, and the bent piece, the permeation cloth 2 and the bottom absorbent layer 43 are sewn. This can be done by connecting using L8. Further, the inner edge of the rear edge water-repellent cloth 52 is bent downward, and the bent piece, the permeation cloth 2 and the liquid-proof cloth-side absorbent layer 434 are joined together using the sewing thread L9. Can do. When such joining is performed, the sewing threads L8 and L9 can be configured not to be exposed on the skin side of the produced body fluid absorption pad 1.

  Next, the front side surface of the liquid-proof cloth 3 is overlapped with the back side surface of the obtained laminate G, and span yarns and wooly yarns are within a range of about 5 to 7 mm from the front edge and the rear edge of the laminate G. Is sewn by a sewing method such as overlock using a sewing thread L10. Further, the inside of the range from the both side edges of the laminate G to about 5 to 7 mm is sewn by using a sewing method such as two flats using a sewing thread L11 such as a spun thread or a woolly thread. Thereby, the outer peripheral edge of the permeation cloth 2 and the outer peripheral edge of the liquid-proof cloth 3 are joined together by the water repellent cloth 5 to form a bag shape. Although not shown, the outer edge of the water-repellent cloth and the outer peripheral edge of the liquid-proof cloth may be encapsulated by piping. Thus, the bodily fluid absorption pad 1 of this example can be obtained. As shown in FIG. 10 to be described later, the above sewing is performed by laminating the liquid-proof cloth 3 and the laminated body G in this order on the skin side surface of the crotch part 61 of the garment 60, and the front edge and the rear end of the laminated body G. The range from the edge to the inner side of about 5-7mm is sewn by sewing method such as overlock using sewing thread L12 such as spun yarn, woolly yarn, etc., and about 5-7mm from both side edges of the laminate G The range up to the inner side can be sewn by using a sewing method such as two flats using a sewing thread L13 such as a spun thread or a woolly thread. That is, the configuration of the body fluid absorption pad 1 and the attachment of the garment 60 to the crotch 61 can be performed simultaneously.

  As shown in FIG. 1, the body fluid absorbing pad 1 of this example includes a sewing thread L1 when the outer periphery of the through hole 400 is sewn on the front surface of the pad, both side edges of the multilayer laminate 4, and a permeating cloth. The sewing thread L5 at the time of sewing 2 is at least exposed.

  Next, the effect of the bodily fluid absorption pad of this example is demonstrated. In the bodily fluid absorption pad 1 of this example, the bodily fluid quickly permeates from the front side surface to the back side surface of the osmotic cloth 2, and the bodily fluid does not easily spread on the pad front side surface. Therefore, the body fluid absorbing pad 1 is easy for the wearer to feel dry. The body fluid absorption pad 1 includes the multilayer laminate 4 having the specific structure as described above. Therefore, the body fluid that has penetrated into the pad flows below the upper absorbent layer 41 while being absorbed by the upper absorbent layer 41. Here, the upper absorbent layer 41 has a notch 410 extending rearward from a midway portion in the front-rear direction. In addition, a permeation layer 42 that allows the body fluid to permeate from the front side surface to the back side surface is disposed in contact with the back side surface of the upper absorbent layer 41. Therefore, the front side surface of the osmotic layer 42 can be exposed along the notch 410. The portion defined by the front side surface of the permeation layer 42 exposed by the notch 410 and the end surface in the thickness direction of the upper absorbent layer 41 in the notch 410 is a flow for guiding body fluid to the back side of the pad. Functions as a road. That is, the speed at which the body fluid penetrates into the permeation layer 42 is faster than the speed at which the body fluid is absorbed into the upper absorbent layer 41, so that the body fluid is drawn downward by the notch 410 and is disposed below the bottom absorbent layer 43. Is absorbed and retained. Therefore, the body fluid absorbing pad 1 is unlikely to accumulate body fluid on the front side of the pad.

  Furthermore, in the bodily fluid absorption pad 1 of this example, the multilayer laminate 4 has a three-dimensionally formed layer 40. Therefore, when the body fluid comes into contact with the permeation cloth 2 at the position corresponding to the through hole 400, the permeation cloth 2 bends downward due to the weight of the body fluid, and passes through the permeation cloth 2 and the body fluid falls into the through hole 400. Therefore, in the body fluid absorbing pad 1 of this example, the body fluid is less likely to spread on the front side surface of the penetrating cloth 2 and the body fluid is more easily diffused below the penetrating cloth 2 as compared to the case where the three-dimensional formation layer 40 is not provided. Therefore, in the body fluid absorbing pad 1 of this example, the front side surface of the penetrating cloth 2 is difficult to get wet with body fluid, and the dry feeling of the pad front side surface can be improved. The three-dimensionally formed layer 40 has the same absorption function as that of the upper absorbent layer 41. Therefore, the bodily fluid absorption pad 1 of this example easily suppresses the backflow of bodily fluid from below to the top, and the three-dimensionally formed layer 40 can also absorb bodily fluid, contributing to an increase in absorption capacity on the upper side of the pad. can do.

(Example 2)
9 and 10 show a garment having a crotch part according to the second embodiment. In the garment 6 having the crotch part 61 of this example, the body fluid absorption pad 1 of Example 1 is disposed on the skin side of the crotch part 61 and attached to the garment 6. In this example, specifically, the garment 6 having the crotch portion 61 is a sanitary short 60. This will be described in detail below.

  The sanitary shorts 60 includes a front body part 62, a back body part 63, and a crotch part 61 connected between the front body part 62 and the back body part 63 by sewing. The front body part 62 and the back body part 63 are connected to each other by sewing on both side surfaces of the shorts to constitute a shorts body part. In addition, the connection part of both sides of shorts is abbreviate | omitted. In the sanitary shorts 60, the crotch part 61 is moved rearward as a whole by disposing the front end part of the crotch part 61 as close as possible to the lower end edge of the front body part 62. Therefore, the sanitary shorts 60 is designed so that the front end portion of the crotch portion 61 is relatively inconspicuous when viewed from the front.

  The body fluid absorption pad 1 of Example 1 is disposed on the skin side surface of the crotch part 61 of the sanitary shorts 60 and attached to the shorts by sewing. In this example, specifically, the bodily fluid absorption pad 1 is arranged so that the back side surface of the liquid-proof cloth 3 of the bodily fluid absorption pad 1 is in contact with the skin side surface of the crotch part 61. The front end edge and the rear end edge of the bodily fluid absorption pad 1 are sewn to the crotch portion 61 by using a sewing thread L12 such as a spun thread or a woolly thread. Further, the body fluid absorption pad 1 is sewn at both side edges to the crotch portion 61 using a sewing thread L13 such as a spun thread or a woolly thread. Specifically, the sanitary shorts 60 of this example superimposes the liquid-proof cloth 3 and the above-described laminated body G on the skin side surface of the crotch part 61 of the garment 60 in this order, The range from the end edge to the inside of about 5 to 7 mm is sewn by using a sewing method such as overlock using a sewing thread L12 such as a spun thread or woolly thread, and 5 to 7 mm from both side edges of the laminate G. By sewing the inside of the range up to the inside by using a sewing method such as two flats using a sewing thread L13 such as a spun thread or a woolly thread, the configuration of the body fluid absorbing pad 1 and the crotch part 61 of the garment 60 can be obtained. The mounting is performed at the same time. In addition, in this example, the body fluid absorption pad 1 is attached to the sanitary shorts 60 so that its front end edge is disposed below the rear end edge in a worn state.

  Next, the effect of the sanitary shorts 60 of this example will be described. The sanitary shorts 60 of this example uses the body fluid absorption pad 1. Therefore, even when the sanitary shorts 60 of the present example is used for a relatively long time, body fluid does not easily accumulate on the front side of the pad. Therefore, the wearer of the sanitary shorts 60 of the present example can hardly feel wet on the crotch portion even when wearing the physiological shorts for a relatively long time, and can obtain a dry feeling for a long time. In addition, the sanitary shorts 60 of this example is gentle to the wearer's skin due to the soft touch of the body fluid absorbent pad 1 and the excellent dry feeling. Moreover, since the sanitary shorts 60 of this example can be worn directly without using a disposable paper napkin, the amount of disposable paper napkin used can be reduced. As a result, garbage is reduced and it is friendly to the global environment.

  As mentioned above, although the Example of this invention was described in detail, this invention is not limited to the said Example, A various change is possible within the range which does not impair the meaning of this invention.

  For example, in the second embodiment, the body fluid absorbing pad 1 is attached to the sanitary shorts 60 by sewing. However, the body fluid absorbing pad 1 is detachably attached to the sanitary shorts 60 using a double-sided fastener or the like. You can also. In this case, when the body fluid absorption pad 1 is soiled by body fluid, the body fluid absorption pad 1 can be easily removed from the crotch portion 61 and washed. Further, in this case, it becomes easy to replace the body fluid absorbing pad 1 with a new one when the body fluid absorbing pad 1 becomes old.

  Moreover, in the said Example, although the bodily fluid to be absorbed was demonstrated using the case of menstrual blood or a thing, it is not limited to this but urine etc. may be sufficient.

  Moreover, the form of each layer which comprises a multilayer laminated body is not limited to the Example mentioned above, It can change suitably.
