This is also advantageous in that the space of the groove 212 can be maintained.

  As shown in FIG. 4, the flange portion 211 has a thickness T1, and the groove portion 212 has a thickness T2. The thickness T1 of the flange portion 211 is usually 0.3 to 1.5 mm, preferably 0.6 to 1.4 mm, more preferably 0.8 to 1.2 mm, and the thickness T2 of the groove portion 212 is usually The thickness is 0.1 to 0.5 mm, preferably 0.2 to 0.4 mm, and more preferably 0.2 to 0.3 mm. In addition, the thickness of the buttock and the groove is measured with a 100 mm × 100 mm top sheet sample cut out from a urine collecting pad and a laser displacement meter (for example, a high-precision two-dimensional laser displacement meter LJ-G series manufactured by Keyence Corporation) Using the model: LJ-G030)), it is carried out in a non-contact manner as follows. A top sheet sample is placed on a horizontal measuring table, and the displacement from the measuring table is measured with a laser displacement meter for five different collars, and the average value of the five measurements is defined as the thickness (mm) of the collar. . Similarly, about five different groove parts, the displacement from a measurement stand is measured with a laser displacement meter, and let the average value of five measured values be the thickness (mm) of a groove part.

The interval between two adjacent flange portions 211 is usually equal to the width W2 of the groove portion, and the interval between two adjacent groove portions 212 is usually equal to the width of the flange portion 211. The width W1 of the flange portion 211 is measured as a distance between the boundary lines of the flange portion 211 and the two groove portions 212 located on both sides thereof based on a planar photograph or a plane image of the top sheet 2 in a non-pressurized state. The The width W2 of the groove 212 is the same.

  In the present embodiment, the thickness T1 and the width W1 of the flange 211 are substantially the same in any flange. The same applies to the thickness T2 and the width W2 of the groove 212. However, such conditions are not essential in the urine absorption pad according to the present invention. Therefore, the urine absorbing pad according to the present invention includes, as another embodiment, an embodiment in which the flange portion 211 having a different thickness and width exists, and an embodiment in which the groove portion 212 having a different thickness and width exists. .

  The liquid permeable sheet used as the top sheet 2 is an air-through nonwoven fabric. The air-through nonwoven fabric in which the ridge groove structure 210 is formed is, for example, after forming the ridge groove structure 210 on a web (fleece) containing thermoplastic resin fibers, and then blowing hot air to intersect the thermoplastic resin fibers in the web.

  Examples of the method for forming the groove structure 210 on the web include the methods described in JP-A-2008-25079, JP-A-2008-23326, JP-A-2009-30218, and the like. According to these methods, the web is placed on a breathable support member (for example, a net-like support member), and the gas (usually air) is continuously formed on the upper surface of the web while moving the breathable support member in a predetermined direction. Can be formed on the web. In addition, in the area | region where gas was sprayed, while the groove part 212 extended in the moving direction of a breathable support member is formed, the collar part 211 is formed between the two adjacent groove parts 212. FIG. At this time, since the fibers in the region where the gas is blown move to both sides of the groove portion 212, the basis weight of the flange portion 211 is usually higher than the basis weight of the groove portion 212. The number, interval, basis weight, fiber density, and the like of the flange portion 211 and the groove portion 212 are desired by adjusting the number of nozzles, the diameter and pitch, the temperature and injection amount of the gas injected from the nozzle, the tension of the web, and the like. Can be adjusted within the range.

  Examples of the thermoplastic resin constituting the thermoplastic resin fiber contained in the web include polyolefin, polyester, polyamide, and the like. Examples of the polyolefin include, for example, linear low density polyethylene (LLDPE), low density polyethylene (LDPE), medium density polyethylene (MDPE), high density polyethylene (HDPE), polypropylene, polybutylene, and copolymers based on these (for example, Ethylene-vinyl acetate copolymer (EVA), ethylene-ethyl acrylate copolymer (EEA), ethylene-acrylic acid copolymer (EAA), ionomer resin), and the like. Examples of the polyester include linear or branched carbon atoms of up to 20 including polyethylene terephthalate (PET), polytrimethyl terephthalate (PTT), polybutylene terephthalate (PBT), polylactic acid, and polyglycolic acid.

Examples of the polyamide include 6-nylon and 6,6-nylon. The thermoplastic resin fiber is preferably subjected to a hydrophilic treatment. Examples of the hydrophilic treatment of the thermoplastic resin fiber include, for example, a treatment using a surfactant, a hydrophilic agent, etc. (for example, kneading a surfactant inside the fiber, coating a surfactant on the fiber surface, etc.) Plasma processing etc. are mentioned.

  The thermoplastic resin fiber may be composed of one kind of thermoplastic resin, but is preferably a composite fiber containing two or more kinds of thermoplastic resins. A preferable composite fiber is a core-sheath type composite fiber. As the thermoplastic resin forming the sheath component of the core-sheath composite fiber, a thermoplastic resin having a melting point lower than that of the thermoplastic resin forming the core component is selected. Examples of the core component of the sheath-core composite fiber and the thermoplastic resin forming the sheath component include olefin resins such as polyethylene and polypropylene, polyamide resins such as nylon, polyester resins, polyacrylonitrile resins, and the like. . The thermoplastic resin forming the sheath component is preferably polyethylene (for example, high density polyethylene, low density polyethylene, linear low density polyethylene, a mixture of these polyethylenes, etc.), and the thermoplastic resin forming the core component is Polypropylene and polyester are preferable. The core-sheath type composite fiber is preferably one in which the center positions of the core component and the sheath component are substantially the same, and does not exhibit spiral crimp caused by heating.

  The collar part 211 (projection strip extending in the longitudinal direction of the urine removing pad 1) in the present embodiment is an example of the convex part, and the convex part formed on the skin contact surface of the top sheet 2 is the collar part. It is not limited to 211. As another embodiment, the urine absorbing pad according to the present invention includes an embodiment in which a nonwoven fabric having a skin contact surface on which a large number of convex portions are formed is used as the top sheet 2. In the nonwoven fabric having a skin contact surface on which a large number of convex portions are formed, the thickness of the portion where the convex portion is formed (distance from the bottom surface of the nonwoven fabric to the top of the convex portion), the portion where the convex portion is not formed ( The thickness of the concave portion (the distance from the lower surface of the nonwoven fabric to the deepest portion of the concave portion), the pitch of the convex portion (the distance between the tops of two adjacent convex portions), etc. In consideration of improvement, improvement in touch, etc.), adjustment can be made as appropriate. As a method of manufacturing a nonwoven fabric having a skin contact surface on which a large number of convex portions are formed, a method using gear stretching, a method using heat stretching of heat stretchable fibers and / or a method using heat shrinking of heat shrinkable fibers Etc.

  Examples of the method using gear stretching include the methods described in JP-A Nos. 2004-174234, 2009-160035, 2009-201964, and the like. According to these methods, the first non-woven fabric layer is unevenly shaped by gear stretching, and then partially bonded to the second non-woven fabric layer at a portion other than the convex portion, thereby forming a skin contact having a large number of convex portions. A non-woven fabric having a contact surface can be produced. The convex part in the nonwoven fabric manufactured in this way protrudes to the skin contact surface side, and the inside becomes a cavity. As the shape of the convex part, for example, a flat rectangular parallelepiped or a truncated quadrangular pyramid with a rounded ridgeline, a pyramid with a rounded vertex (for example, a triangular pyramid, a quadrangular pyramid, etc.), and a rounded vertex Examples include a conical shape and an arch shape. For example, the convex portions can be arranged in a staggered pattern in plan view. When the convex portions are arranged in a staggered pattern, one concave portion is located between two adjacent convex portions (that is, four concave portions are located around one convex portion). Examples of the nonwoven fabric used as the first nonwoven fabric layer and the second nonwoven fabric layer include, for example, a spunbond nonwoven fabric, a point bond nonwoven fabric, a spunlace nonwoven fabric, a needle punch nonwoven fabric, a melt blown nonwoven fabric, and a combination thereof (for example, a spunbond, meltblown, Spunbond (SMS) nonwoven fabric etc.) etc. are mentioned. The joining of the first nonwoven fabric layer and the second nonwoven fabric layer can be performed, for example, by heat-sealing thermoplastic resin fibers contained in the first nonwoven fabric layer and / or the second nonwoven fabric layer. The significance and specific examples of the thermoplastic resin fibers are the same as described above.

  Examples of the method using the heat elongation of the heat-extensible fiber and the heat shrinkage of the heat-shrinkable fiber include a method described in JP2012-5701A. According to this method, the heat stretchable fiber layer is provided on the skin contact surface side, and the heat shrinkable fiber layer partially bonded to the heat stretchable fiber layer by the joint portion is provided on the non-skin contact surface side. The laminated sheet was heat-treated, and the heat-extensible fiber layer was raised on the skin contact surface side by heat expansion of the heat-extensible fiber layer and heat contraction of the heat-shrinkable fiber layer, thereby forming a large number of convex portions. A nonwoven fabric having a skin contact surface can be produced. Even if the heat-extensible fiber contained in the heat-extensible fiber layer is a fiber whose actual fiber length is extended by heat treatment (for example, a fiber whose actual fiber length is extended by changing the crystalline state of the resin). The actual fiber length is not elongated by heat treatment, but the fiber with an apparent fiber length (for example, the zigzag-like, Ω-like, spiral-like crimps that have been expressed are released and the apparent (Crimped fiber whose fiber length extends). Various heat-extensible fibers are known (for example, JP-A No. 2004-218183, JP-A No. 2005-350836, JP-A No. 2007-303035, JP-A No. 2007-204899, JP-A No. 2007-204901). No. 2007, No. 2007-204902, No. 2008-101285, etc.) can be appropriately selected and used. The heat-shrinkable fibers contained in the heat-shrinkable fiber layer may be fibers whose actual fiber length is shortened by heat treatment, and the actual fiber length is not shortened by heat treatment, but the apparent fiber length May be a fiber (for example, a latently crimpable fiber in which a zigzag-like, Ω-like, or spiral-like crimp is developed and an apparent fiber length is shortened). Various heat-shrinkable fibers are known (for example, JP-A-9-296325, JP-A-2-191720, JP-A-2007-177335) and can be appropriately selected and used. The joint that partially joins the heat-extensible fiber layer and the heat-shrinkable fiber layer is, for example, a recess formed by heat embossing. For example, the joints can be arranged in a staggered pattern in plan view. Since one region surrounded by a plurality of joints rises to the skin contact surface side starting from these joints, one convex portion is formed. It adjusts suitably in consideration of the formability of the convex part, bulkiness and the like.

  Examples of the method using the heat shrinkage of the heat-shrinkable fiber include methods described in JP 2002-187228 A, JP 2003-247155 A, JP 2007-177340 A, and the like. According to these methods, the heat-shrinkable fiber layer partially bonded to the non-heat-shrinkable fiber layer by the bonding portion has the non-heat-shrinkable fiber layer on the skin-contacting surface side. Heat-treat the laminated sheet on the side, and heat-shrink the heat-shrinkable fiber layer to raise the non-heat-shrinkable fiber layer to the skin-contacting surface, thereby forming a skin-contacting surface on which a large number of convex portions are formed. The nonwoven fabric which has can be manufactured. The non-heat-shrinkable fiber contained in the non-heat-shrinkable fiber layer may be a fiber that does not substantially have heat-shrinkability, or has heat-shrinkability, but its heat shrinkage start temperature is heat shrinkage. Heat shrinkage at a temperature higher than the heat shrinkage start temperature of the heat shrinkable fiber contained in the heat shrinkable fiber layer (that is, at a temperature lower than the heat shrinkage start temperature of the heat shrinkable fiber contained in the heat shrinkable fiber layer) Fiber).

  Examples of the method utilizing the thermal elongation of the thermally stretchable fiber include methods described in JP-A-2005-350836, JP-A-2010-168715, and the like. According to these methods, the heat stretchable fiber layer is provided on the skin contact surface side, and the non-heat stretchable fiber layer partially bonded to the heat stretchable fiber layer by the joint portion is provided on the non-skin contact surface side. The non-woven fabric having a skin contact surface on which a large number of convex portions are formed by heat-treating the laminated sheet having a heat-extensible fiber layer and raising the heat-extensible fiber layer toward the skin contact surface side Can be manufactured. The non-heat-stretchable fiber contained in the non-heat-stretchable fiber layer may be a fiber that does not substantially have heat-stretchability, or has heat-stretchability, but its heat-stretch start temperature is heat-stretching. The fiber is higher in temperature than the heat elongation start temperature of the heat stretchable fiber contained in the stretchable fiber layer (that is, substantially heat stretched at a temperature lower than the heat stretch start temperature of the heat stretchable fiber contained in the heat stretchable fiber layer). Fiber). Examples of non-heat-extensible fibers include regenerated fibers such as rayon; semi-synthetic fibers such as acetate; natural fibers such as cotton and wool; polyolefins (for example, polyethylene and polypropylene), polyesters (for example, polyethylene terephthalate), Examples thereof include thermoplastic resin fibers such as polyamide.

The basis weight of the top sheet 2 can be appropriately adjusted in consideration of touch and the like. The basis weight of the air-through nonwoven fabric is usually 20 to 40 g / m ^2, preferably 25 to 35 g / m ^2.

  From the viewpoint of improving the concealability of the top sheet 2, the top sheet 2 can contain an inorganic filler such as titanium oxide, barium sulfate, or calcium carbonate. When the top sheet 2 includes a core-sheath composite fiber, the inorganic filler can be contained in one or both of the core component and the sheath component.

  In the present embodiment, another liquid permeable sheet is not interposed between the top sheet 2 and the absorbent layer 4, but such a condition is not essential in the urine absorption pad according to the present invention. Therefore, the urine absorption pad according to the present invention includes an embodiment in which another liquid-permeable sheet is disposed between the top sheet 2 and the absorbent layer 4 as another embodiment. Examples of the liquid permeable sheet other than the top sheet 2 include a second sheet disposed between the top sheet 2 and the absorbent layer 4. Examples of the liquid permeable sheet used as the second sheet include a nonwoven fabric, a woven fabric, and a synthetic resin film in which liquid permeable holes are formed. Among these, a nonwoven fabric is preferable.

  The back sheet 3 is a liquid-impermeable sheet that can prevent leakage of urine absorbed and retained by the absorption layer 4. Examples of liquid-impermeable sheets include waterproof nonwoven fabrics (eg, point bond nonwoven fabrics, spunbond nonwoven fabrics, spunlace nonwoven fabrics, etc.), synthetic resin (eg, polyethylene, polypropylene, polyethylene terephthalate, etc.) films, nonwoven fabrics, and the like. Examples include composite sheets with synthetic resin films. In the present embodiment, another liquid-impermeable sheet is not interposed between the back sheet 3 and the absorbent layer 4, but such a condition is not essential in the urine absorption pad according to the present invention. Therefore, the urine absorption pad according to the present invention includes an embodiment in which another liquid-impermeable sheet is disposed between the back sheet 3 and the absorbent layer 4 as an embodiment other than the present embodiment.

  The material, thickness, basis weight, and the like of the backsheet 3 can be appropriately adjusted within a range in which leakage of urine absorbed and retained by the absorbent layer 4 can be prevented. The back sheet 3 preferably has air permeability or moisture permeability in addition to liquid impermeability in order to reduce stuffiness when worn.

  The top sheet 2 and the back sheet 3 are joined at peripheral edges that overlap each other. Examples of the bonding mode include bonding by heat embossing, bonding by ultrasonic embossing, and bonding by a hot melt adhesive.

  As shown in FIGS. 1 to 3, the absorbent layer 4 is disposed between the top sheet 2 and the back sheet 3. As shown in FIG. 1, the absorbent layer 4 is arranged so as to reach from the ventral side portion 11 to the back side portion 13 through the crotch portion 12.

  As shown in FIGS. 1 to 3, the absorption layer 4 includes a first layer 41 and a second layer 42. However, such conditions are not essential in the urine absorption pad according to the present invention. Therefore, the urine absorption pad according to the present invention includes, as another embodiment, an embodiment in which the absorption layer 4 is composed of a single layer, and 1 or 2 in which the absorption layer 4 is other than the first layer 41 and the second layer 42. Embodiments having the above layers are included.

  As shown in FIGS. 1 to 3, the first layer 41 has a through-hole 51 that penetrates the first layer 41 in the thickness direction, and the second layer 42 has the second layer 42. A through hole 52 penetrating in the thickness direction is formed. As shown in FIG. 1, the through holes 51 and 52 are located in the crotch portion 12 of the urine collection pad 1 and extend in the longitudinal direction of the urine collection pad 1 at approximately the center in the short direction of the urine collection pad 1. Exist. As shown in FIGS. 1 to 3, the first layer 41 and the second layer 42 are stacked so that the positions of the through holes 51 and 52 coincide (that is, the through holes 51 and 52 communicate with each other). Thereby, the through-hole 5 which penetrates the absorption layer 4 in the thickness direction is formed by the through-holes 51 and 52. Therefore, as shown in FIG. 1, the through-hole 5 is located in the crotch portion 12 of the urine removing pad 1 and the urine at the approximate center of the short-side direction of the urine removing pad 1 as with the through-holes 51 and 52. It extends in the longitudinal direction of the take pad. For this reason, the position of the through hole 5 easily matches the position of the wearer's genital area (urine excretion opening), and the fit of the urine collecting pad 1 to the wearer is improved. Moreover, since the part which a wearer's shadow (urine excretion opening | mouth) contacts becomes difficult to become a moist state, a wearer's discomfort is prevented.

  The urine absorption pad according to the present invention includes an embodiment in which a concave portion opened on the top sheet 2 side is formed in the absorbent layer 4 instead of the through hole 5. The absorption layer 4 having a recess opening on the top sheet 2 side can be formed, for example, by laminating a first layer 41 having a through hole 51 and a second layer 42 having no through hole 52.

  As shown in FIG. 1 and FIG. 2, the planar view shape of the first layer 41 is a bowl shape with a substantially central portion in the longitudinal direction narrowed, and the planar view shape of the second layer 42 is a substantially rectangular shape. However, such conditions are not essential in the urine absorption pad according to the present invention. Therefore, the urine absorbing pad according to the present invention includes, as another embodiment, an embodiment in which the first layer 41 has a shape other than a bowl shape and the second layer 42 has a shape other than a rectangular shape.

  As shown in FIGS. 1 to 3 and 5, the end edge 411 on one side in the longitudinal direction of the first layer 41 substantially coincides with the end edge 421 on the one side in the longitudinal direction of the second layer 42. The edge portion 412 on the other side in the longitudinal direction of the first layer 41 substantially coincides with the edge portion 422 on the other side in the longitudinal direction of the second layer 42. On the other hand, the end portion 413 on one side in the short direction of the first layer 41 is located on the outer side in the short direction than the end portion 423 on one side in the short direction of the second layer 42. The edge portion 414 on the other side in the lateral direction of the second layer 42 is located on the outer side in the lateral direction with respect to the edge portion 424 on the other side in the lateral direction of the second layer 42. Thus, the edge portions 421 and 422 of the second layer 42 coincide with the edge portions 411 and 412 of the first layer 41, and the edge portions 423 and 424 of the second layer 42 are the same as those of the first layer 41. Since it is located inside the edge portions 413 and 414, the planar view shape of the absorption layer 4 matches the planar view shape of the first layer 41. That is, the shape of the absorption layer 4 in plan view is a bowl shape with a substantially central portion in the longitudinal direction constricted. Thereby, the narrow part of the absorption layer 4 is easy to fit between a wearer's crotch, and the position of the absorption layer 4 becomes easy to correspond with the position of a wearer's crotch. However, such conditions are not essential in the urine absorption pad according to the present invention. Therefore, the urine absorption pad according to the present invention is an embodiment in which at least one of the edge portions 411 and 412 of the first layer 41 extends in the longitudinal direction from the edge portion of the corresponding second layer 42, In addition, an embodiment in which at least one of the edge portions 421 and 422 of the second layer 42 extends in the longitudinal direction from the edge portion of the corresponding first layer 41 is included.

  In the present embodiment, the positional relationship between the edge 413 of the first layer 41 and the edge 423 of the second layer 42, and the edge 414 of the first layer 41 and the edge 424 of the second layer 42. Is set as follows.

Meanwhile edge side) is substantially parallel to the imaginary straight line L _R. Therefore, the distance D ₁ between the virtual straight line _LR and the edge portion 413 of the first layer 41 is substantially constant. The distance D ₁ between the virtual straight line _LR and the edge 413 of the first layer 41 is usually 40 to 100 mm, preferably 50 to 70 mm.

Let D ₂ be the distance to the point that intersects the edge 423. In the present embodiment, since the second layer 42 has a substantially rectangular shape in plan view, the second layer 42 extends from a point intersecting the virtual straight line L _P to a point intersecting the virtual straight line L _{Q in} the edge portion 423 of the second layer 42. portion standing is substantially parallel to the imaginary straight line L _R. Therefore, the distance D ₂ between the virtual straight line _LR and the edge 423 of the second layer 42 is substantially constant. Virtual line L _R and the distance D ₂ between the edge portion 423 of the second layer 42 is usually 30～90Mm, preferably 40-60 mm.

In the virtual plane shown in FIG. 5, a virtual straight line extending in the Y direction from any point on the line segment having both ends of the point I _PS and the point I _QS through the arbitrary point is formed on the first layer 41.

Therefore, the distance D ₃ between the virtual straight line L _S and the edge portion 414 of the first layer 41 is substantially constant. A distance D ₃ between the virtual straight line L _S and the edge 414 of the first layer 41 is usually 40 to 100 mm, preferably 50 to 70 mm.

In the virtual plane shown in FIG. 5, an imaginary straight line extending in the Y direction from the arbitrary point on the line segment having both ends of the point I _PS and the point I _QS through the arbitrary point is the second layer 42. Let D ₄ be the distance to the point that intersects the edge 424. In the present embodiment, since the second layer 42 has a substantially rectangular shape in plan view, the second layer 42 extends from a point intersecting the virtual straight line L _P to a point intersecting the virtual straight line L _{Q in} the edge portion 424 of the second layer 42. The existing portion is substantially parallel to the virtual straight line L _S. Accordingly, the distance D ₄ between the imaginary straight line L _S and the edge 424 of the second layer 42 is substantially constant. The distance D ₄ between the virtual straight line L _S and the edge 424 of the second layer 42 is usually 30 to 90 mm, preferably 40 to 60 mm.

Under the above conditions, the positional relationship between the edge 413 of the first layer 41 and the edge 423 of the second layer 42 is set so as to satisfy D ₂ > D _1/2 , and the edge of the first layer 41 positional relationship between the edge 414 and the edge 424 of the second layer 42 is set so as to satisfy D _4> D _3/2.

In addition, the measurement of the thickness of an absorption layer is a 100 mm x 100 mm absorption layer sample cut out from the urine collection pad, a commercially available thickness measuring instrument (for example, PE257 manufactured by PEACOCK, measurement surface 50 mm (diameter), measurement pressure 3 g. / Cm ² ) and is carried out as follows. Using a thickness meter, pressurize five different parts of the absorbent layer sample at a constant pressure of 3 g / cm ² , measure the thickness after 10 seconds of pressurization at each part, and calculate the average of the five measured values as thickness (mm) And

  The lengths, widths, and the like of the through holes 51 and 52 can be appropriately adjusted based on the sizes of the first layer 41 and the second layer 42. The width | variety of the through-hole 51 is 5.0-50 mm normally, Preferably it is 10-20 mm. The width of the through hole 52 is equal to or smaller than the width of the through hole 51, and is usually 5.0 to 40 mm, preferably 10 to 15 mm.

Even if the width and length of the through-hole 51 are equal to or larger than the width and length of the through-hole 52, even if some deviation occurs in the process of laminating the first layer 41 and the second layer 42. The size of the through hole 5 viewed from the top sheet 2 side surface of the absorbent layer 4 is kept substantially constant. Further, a step is generated on the inner wall surface of the through hole 5 and the inner surface area of the through hole 5 is increased, so that the urine absorption capacity of the absorption layer 4 in the portion where the through hole 5 is formed is improved.

  As shown in FIG. 3, the width of the through hole 51 is substantially constant from the top sheet 2 side surface of the first layer 41 to the back sheet 3 side surface. Similarly, the width of the through hole 52 is substantially constant from the top sheet 2 side surface of the second layer 42 to the back sheet 3 side surface. However, such conditions are not essential in the urine absorption pad according to the present invention. Therefore, as another embodiment, the urine absorbing pad according to the present invention has one or both of the width of the through hole 51 and the width of the through hole 52 being different from the top sheet 2 side surface of the first layer 41 on the back sheet 3 side. Includes embodiments that narrow or widen toward the surface.

Occurrence of local urine saturation can be prevented.

  The absorbent layer 4 may have a core wrap that covers the first layer 41 and the second layer 42. By covering the first layer 41 and the second layer 42, which are layered molded bodies of absorbent material, with a core wrap, the collapse of the first layer 41 and the second layer 42 can be prevented. The core wrap is a liquid-permeable sheet through which urine excreted from the wearer can permeate. Examples of the core wrap include a nonwoven fabric, a woven fabric, and a synthetic resin film in which liquid permeation holes are formed, and a nonwoven fabric is preferable. The core wrap may cover the whole of the surfaces of the first layer 41 and the second layer 42, or may cover a part thereof.

The topsheet surface of the urine absorbing pad 1, since folded virtual straight line L ₁ as an axis, the virtual straight line L ₁ is the outermost of the Y-direction in the curved surface drawn by the top sheet side surface of the urine absorbing pad 1.

  As shown in FIGS. 9 and 10, the first portion 40 a of the absorbent layer 4 is bent with the second portion 40 b of the absorbent layer 4 in the thickness direction of the first portion 40 a of the absorbent layer 4 by bending in the first stage. The fourth portion 40d of the absorption layer 4 overlaps the sixth portion 40f of the absorption layer 6 in the thickness direction of the fourth portion 40d of the absorption layer 4, and the fifth portion 40e of the absorption layer 4 The fifth portion 40e overlaps the eighth portion 40h of the absorption layer 4 in the thickness direction of the fifth portion 40e.

The absorption layer 4 is in the embodiments and absorbing layer having no sixth portion 40f has no embodiment of the eighth portion 40h, also bent in the top sheet 2 side urine absorbing pad 1 is in the virtual straight line L _1, Such an overlap does not occur.

(2) In the second step the second stage, the urine absorbing pad 1 after the first stage is folded in the top sheet 2 side in the virtual straight line L _2. Here, bending of the top sheet 2 side of the imaginary straight line L _2, the virtual straight line L ₂ means the bending hidden inside (the so-called valley fold).

  As shown in FIG. 9 and FIG. 10, the bending in the second stage is such that the top sheet side surfaces of the third portion 10 c, the seventh portion 10 g and the ninth portion 10 i of the urine removing pad 1 are respectively on the urine removing pad 1. The first portion 10a, the fourth portion 10d, and the fifth portion 10e of the first portion 10a are performed so as to face the surface of the top sheet 2 side. The bending in the second stage is such that the top sheet side surfaces of the third portion 10c, the seventh portion 10g and the ninth portion 10i of the urine removing pad 1 are the first portion 10a and the fourth portion of the urine removing pad 1, respectively. 10d and the 5th part 10e may be implemented so that it may contact with the top sheet 2 side surface, and you may implement so that it may not contact.

Since the top sheet side surface of the urine picking pad 1 is bent with the virtual straight line L ₂ as an axis, the virtual straight line L ₂ is located on the outermost side in the Y direction on the curved surface drawn by the top sheet side surface of the urine collecting pad 1. .

  As shown in FIGS. 9 and 10, the first portion 40a of the absorption layer 4 overlaps the third portion 40c of the absorption layer 4 in the thickness direction of the first portion 40a by bending in the second stage. Similarly, the fourth portion 40d of the absorption layer 4 overlaps the seventh portion 40g of the absorption layer 4 in the thickness direction of the fourth portion 40d, and the fifth portion 40e of the absorption layer 4 is the thickness of the fifth portion 40e. In the vertical direction, it overlaps the ninth portion 40 i of the absorption layer 4.

However, the absorption layer 4 is in the embodiment without and absorbing layer 4 a seventh portion 40g is an embodiment without a ninth portion 40i, even if the urine absorbing pad 1 is bent to the topsheet 2 side with the virtual straight line L ₂ Such an overlap does not occur.

In the present embodiment, the second stage (folding along the virtual straight line L ₂ ) is performed after the first stage (folding along the virtual straight line L ₁ ). However, such a condition is not essential in the urine collecting pad 1 according to the present invention. Therefore, the urine absorbing pad 1 according to the present invention includes, as another embodiment, an embodiment in which the bending at the virtual straight line L ₂ is performed before the bending at the virtual straight line L ₁ .

As shown in FIG. 8, the first overlapping portion 40a ₁ and the second overlapping portion 40a ₂ are formed on both sides in the Y direction of the non-overlapping portion 40a ₃ . In the present embodiment, as shown in FIG. 9, the first overlapping portion 40a ₁ and the second overlapping portion 40a ₂ are formed around the non-overlapping portion 40a ₃ .

(3) Third Stage In the third stage, the urine absorbing pad 1 after the second stage is bent toward the top sheet 2 along the virtual straight line L ₃ . Here, bending of the top sheet 2 side of the imaginary straight line L _3, means folding the virtual straight line L ₃ is inside the (so-called valley fold).

  As shown in FIGS. 7 and 8, the folding in the third stage is such that the back sheet side surfaces of the sixth portion 10f and the seventh portion 10g overlaid on the fourth portion 10d are overlaid on the first portion 10a, respectively. It is carried out so as to face the back sheet side surfaces of the second part 10b and the third part 10c. The bending in the third stage is performed by the second portion 10b and the third portion 10c in which the back sheet side surfaces of the sixth portion 10f and the seventh portion 10g overlapped with the fourth portion 10d are overlapped with the first portion 10a. It may be carried out so as to be in contact with the back sheet side surface of the sheet, or may be carried out so as not to be in contact.

The topsheet surface of the urine absorbing pad 1, since folded virtual straight line L ₃ as an axis, a virtual straight line L ₃ is the outermost in the X direction in the curved surface drawn by the top sheet side surface of the urine absorbing pad 1.

Due to the bending in the third stage, the first overlapping portion 40a ₁ of the first portion 40a of the absorbing layer 4 becomes the second portion of the absorbing layer 4 in order from the first overlapping portion 40a ₁ side in the thickness direction of the first portion 40a. 40b overlaps with the sixth portion 40f and the fourth portion 40d. Similarly, the second overlapping portion 40a ₂ of the first portion 40a of the absorbing layer 4 has the third portion 40c and the seventh portion of the absorbing layer 4 in order from the second overlapping portion 40a ₂ side in the thickness direction of the first portion 40a.

The absorption layer 4 is an embodiment without a seventh portion 40 g, the second overlapping portion 40a ₂ of the first portion 40a, in the thickness direction of the first portion 40a, the absorption layer from the second overlapping portion 40a ₂ side in this order 4 Of the second portion 40c and the fourth portion 40d.

(4) Fourth Stage In the fourth stage, after the third stage, the urine collecting pad 1 is bent along the virtual straight line L ₄ to the top sheet 2 side. Here, bending of the top sheet 2 side of the imaginary straight line L ₄ are meant folding imaginary straight line L ₄ is inside the (so-called valley fold).

As shown in FIGS. 7 and 8, is folded in the fourth stage, the back sheet side surface of the eighth portion 10h and the ninth portion 10i that is bent in the virtual straight line L ₁ and the virtual straight line L ₂ is a third virtual It is carried to face the back sheet side surface of the fourth portion 10d which is bent in a straight line L _3. Incidentally, folding the in the fourth stage, the fourth portion 10d backsheet side surface of the eighth portion 10h and the ninth portion 10i that is bent in the virtual straight line L ₁ and the virtual straight line L ₂ is folded in the virtual straight line L ₃ It may be carried out so as to be in contact with the back sheet side surface of the sheet, or may be carried out so as not to be in contact.

The topsheet surface of the urine absorbing pad 1, since folded virtual straight line L ₄ as an axis, the virtual straight line L ₄ are, the outermost in the X direction in the curved surface drawn by the top sheet side surface of the urine absorbing pad 1.

Due to the bending in the fourth stage, the first overlapping portion 40a ₁ of the first portion 40a of the absorbing layer 4 becomes the second portion of the absorbing layer 4 in order from the first overlapping portion 40a ₁ side in the thickness direction of the first portion 40a. 40b, the sixth portion 40f, the fourth portion 40d, the eighth portion 40h, and the fifth portion 40e overlap. Similarly, the second overlapping portion 40a ₂ of the first portion 40a of the absorbing layer 4 has the third portion 40c and the seventh portion of the absorbing layer 4 in order from the second overlapping portion 40a ₂ side in the thickness direction of the first portion 40a. It overlaps with the portion 40g, the fourth portion 40d, the ninth portion 40i, and the fifth portion 40e.

In the absorption layer 4 is an embodiment without a eighth portion 40h, a first overlapping portion 40a ₁ of the first portion 40a is absorbed in the thickness direction of the first portion 40a, in order from the first overlapping portion 40a ₁ side The second portion 40b, the sixth portion 40f, the fourth portion 40d, and the fifth portion 40e of the layer 4 overlap. The absorption layer 4 is an embodiment without a ninth portion 40i, the second overlapping portion 40a ₂ of the first portion 40a, in the thickness direction of the first portion 40a, the absorption layer from the second overlapping portion 40a ₂ side in this order 4 The third portion 40c, the seventh portion 40g, the fourth portion 40d, and the fifth portion 40e overlap.

  Through the first to fourth steps, the folded structure shown in FIGS. 7 and 8 is formed. In this embodiment, after the first stage and the second stage, the third stage and the fourth stage are performed, but such a condition is not essential in the urine collecting pad according to the present invention. Therefore, the urine absorption pad according to the present invention is an embodiment in which the third stage is performed after the first stage and the second stage, but the fourth stage is not performed, and after the first stage and the second stage. The third stage is not implemented, but the fourth stage encompasses the implemented embodiment.

In the folded urine collecting pad 1, the first overlapping portion 40 a ₁ and the second overlapping portion 40 a ₂ of the first portion 40 a of the absorption layer 4 are respectively formed in the absorption layer 4 in the thickness direction of the first portion 40 a. while the second portion 40b and the third portion 40c of the overlap, the non-overlapping portion 40a _3, any overlap of the second portion 40b and the third portion 40c in the thickness direction of the absorbent layer 4 of the first part 40a Not. Therefore, when the pressure which compresses the urine picking pad 1 in the thickness direction of the 1st part 40a of the absorption layer 4 is applied to the urine picking pad 1 (for example, several folded urine picking pads 1 are the absorption layer 4). The second portion 40b of the absorbent layer 4 overlying the first overlapping portion 40a ₁ , and the second portion 40b when the first portion 40a is compressed in the thickness direction of the first portion 40a. a third portion 40c of the absorbent layer 4 that overlaps the overlapping portion 40a ₂ is to function as a pressure buffer layer, to protect the non-overlapping portion 40a ₃ from the pressure. In particular, in the present embodiment, a plurality of portions of the absorption layer 4 that overlap the first overlapping portion 40a ₁ (second portion 40b, sixth portion 40f, fourth portion 40d, eighth portion 40h, and fifth portion 40e). And a plurality of portions (the third portion 40c, the seventh portion 40g, the fourth portion 40d, the ninth portion 40i, and the fifth portion 40e) of the absorption layer 4 overlapping the second overlapping portion 40a ₂ are pressure buffering. Acts as a layer and effectively protects non-overlapping parts from pressure. For this reason, the top sheet portion arranged in the non-overlapping portion 40a ₃ is not easily pressed by the pressure applied to the urine collecting pad 1. Moreover, since the non-overlapping portion 40a ₃ through hole 5 is located, the topsheet portion disposed in the non-overlapping portion 40a ₃ can also escape into the through hole 5 as being pressed. Thus, even if the pressure to compress the urine absorbing pad 1 in the thickness direction of the first portion 40a of the absorber layer 4 is applied to the urine absorbing pad 1, the top sheet portion disposed in the non-overlapping portion 40a ₃ is pressed Even if pressed, it is possible to escape into the through hole 5, so that the shape of the flange portion 211 in the top sheet portion arranged in the non-overlapping portion 40 a ₃ is easily maintained. Such an operational effect is also exhibited in the embodiment in which a recess that opens to the top sheet 2 side is formed in the absorbent layer 4 instead of the through hole 5.

In folding the urine absorbing pad 1 in the state, the first overlapping portion of the portion 40a ₁ of the first portion 40a of the absorber layer 4, a high basis weight of the second portion 40b of the absorbing layer 4 in the thickness direction of the first part 40a The portions overlap, and the other portion has the low basis weight portion of the second portion 40b of the absorbent layer 4 in the thickness direction of the first portion 40a. Therefore, when the pressure which compresses the urine picking pad 1 in the thickness direction of the 1st part 40a of the absorption layer 4 is applied to the urine picking pad 1 (for example, several folded urine picking pads 1 are the absorption layer 4). first when part 40a adjacent to each other in a compressed state in the thickness direction to the are housed in a container), the pressure, of the first overlapping portion 40a _1, the high of the second portion 40b of the absorbing layer 4 It is easy to transmit to the part with which the basic weight part has overlapped, and it is difficult to transmit to the part with which the low basic weight part of the 2nd part 40b of the absorption layer 4 has overlapped. In particular, since the thickness of the high basis weight portion of the second portion 40b of the absorbent layer 4 is larger than the thickness of the low basis weight portion of the second portion of the absorbent layer 4, the pressure is within the first overlapping portion 40a ₁ . It is easy to be transmitted to the portion where the high basis weight portion of the second portion 40b of the absorbent layer 4 is overlapped, and is difficult to be transmitted to the portion where the low basis weight portion of the second portion 40b of the absorbent layer 4 is overlapped. Therefore, the top sheet portion arranged in the portion where the low basis weight portion of the second portion 40b of the absorbent layer 4 is overlapped in the first overlapping portion 40a ₁ is pressed by the pressure applied to the urine absorbing pad 1. It is difficult to maintain the form of the flange 211 in the top sheet portion.

In folding the urine absorbing pad 1 in the state, the second overlapping portion of the portion 40a ₂ of the first portion 40a of the absorber layer 4, a high basis weight of the third portion 40c of the absorbent layer 4 in the thickness direction of the first part 40a The portions overlap each other, and the low basis weight portion of the third portion 40c of the absorbent layer 4 overlaps the other portions in the thickness direction of the first portion 40a. Therefore, when the pressure which compresses the urine picking pad 1 in the thickness direction of the 1st part 40a of the absorption layer 4 is applied to the urine picking pad 1 (for example, several folded urine picking pads 1 are the absorption layer 4). first when part 40a adjacent to each other in a compressed state in the thickness direction to the are housed in a container), pressure in the second overlapping portion 40a _2, high of the third portion 40c of the absorbent layer 4 It is easy to transmit to the part with which the basic weight part has overlapped, and it is difficult to transmit to the part with which the low basic weight part of the 3rd part 40c of the absorption layer 4 has overlapped. In particular, since the thickness of the high basis weight portion of the third portion 40c of the absorbent layer 4 is larger than the thickness of the low basis weight portion of the third portion 40c of the absorbent layer 4, the pressure is within the second overlapping portion 40a ₂ . The high basis weight portion of the third portion 40c of the absorbent layer 4 is easily transmitted to the overlapping portion, and the low basis weight portion of the third portion 40c of the absorbent layer 4 is not easily transmitted to the overlapping portion. Therefore, the top sheet portion arranged in the portion of the second overlapping portion 40a ₂ where the low basis weight portion of the third portion 40c of the absorbent layer 4 overlaps is pressed by the pressure applied to the urine collecting pad 1. It is difficult to maintain the form of the flange 211 in the top sheet portion.

  As shown in FIGS. 11 and 12, a urine collection pad storage product 100 that is an embodiment of the urine collection pad storage product according to the present invention has a plurality of urine collection pads 1 and a plurality of urine collection pads 1 folded. And a container 7 stored in a state where the structure is maintained.

  As shown in FIGS. 11 and 12, the number of urine collecting pads 1 stored in the container 7 is plural. However, such a condition is not essential in the urine collecting pad storage product according to the present invention. Therefore, the urine collection pad storage product according to the present invention includes an embodiment in which the number of the urine collection pads 1 stored in the container 7 is one as another embodiment.

  As shown in FIG. 11 and FIG. 12, the plurality of urine collecting pads 1 are arranged in the vertical direction and stored in the container 7 in a state in which the folding structure of each urine collecting pad 1 is maintained. However, such a condition is not essential in the urine collecting pad storage product according to the present invention. Therefore, the urine collection pad storage product according to the present invention includes an embodiment in which a plurality of urine collection pads 1 are arranged side by side and stored in the container 7 as another embodiment.

  The container 7 is not particularly limited as long as it can store a plurality of urine collecting pads 1. The container 7 is a bag-shaped molded product made of packaging material such as a plastic film.

In the urine collection pad storage product 100, when a plurality of urine collection pads 1 are stored in a container adjacent to each other in a compressed state in the thickness direction of the first portion 40a of the absorbent layer 4, the urine collection pad 1 The effect of is remarkable. That is, in such a case, the pressure for compressing the urine absorbing pad 1 in the thickness direction of the first portion 40a of the absorbent layer 4 is applied to the urine collecting pad 1, but the non-overlapping portion of the first portion 40a of the absorbent layer 4 is applied. Since the top sheet portion arranged at 40a ₃ is hardly pressed and can escape into the through-hole 5 even if pressed, the shape of the flange portion 211 in the top sheet portion arranged at the non-overlapping portion 40a ₃ is maintained. Easy to be.
