Description

  The present invention relates to an absorbent pad laminate in which a plurality of absorbent pads for containing excrement such as urine are laminated, and an absorbent article provided with the absorbent pad laminate.

  Conventionally, an absorbent pad laminate in which a plurality of absorbent pads for containing excrement such as urine is laminated is known. Such an absorbent pad laminate is excellent in handling because a new absorbent pad can be used by removing the absorbent pad in order from the top without replacing the pad itself. For example, Patent Document 1 discloses an absorbent pad laminate in which a plurality of absorbent pads are stacked and the width of the lower absorbent pad is reduced.

JP 2011-72335 A

  The absorbent pad laminate is used by removing the absorbent pad in order from the top. However, when the absorbent pad laminate is attached between the wearer's crotch, the work of removing the absorbent pad tends to be difficult. Further, depending on the use situation of the absorbent pad, it may be desired to remove two or more absorbent pads at a time. However, in the conventional absorbent pad laminate, the absorbent pads are arranged one by one in order from the top. It is necessary to remove, and the removal work tends to be troublesome.

  The present invention has been made in view of the above circumstances, and an object of the present invention is to make it possible to easily discriminate an arbitrary absorbent pad and to easily remove one or more absorbent pads. It is providing the absorbent article provided with the body and the said absorbent pad laminated body.

  The absorbent pad laminate of the present invention that has been able to solve the above-mentioned problems is a laminate of a plurality of absorbent pads, the uppermost first absorbent pad, and the second absorbent provided on the lower side. An absorbent pad laminate having a pad, wherein the second absorbent pad extends outward from the outer edge of the first absorbent pad, and the first absorbent pad and the second absorbent pad have different colors or patterns It has the characteristic in having. In the absorbent pad laminate of the present invention, the first absorbent pad and the second absorbent pad can be easily discriminated when viewed from the upper surface side. It is easy to select the absorbent pad to be removed from the two absorbent pads and remove only the first absorbent pad or remove both the first absorbent pad and the second absorbent pad at once. Therefore, it is possible to easily remove the absorbent pad, and it is possible to use the absorbent pad laminate in a fresh state by removing the desired absorbent pad.

  The first absorbent pad is preferably white and the second absorbent pad is preferably colored other than white. Since the absorbent pad is generally white, if the first absorbent pad that is most noticeable when using the absorbent pad laminate has a white color, the user can visually recognize the absorbent pad laminate. It becomes difficult to remember a sense of incongruity. Moreover, since it is not necessary to color the 1st absorbent pad, the manufacturing cost of an absorbent pad laminated body can be held down.

  The second absorbent pad preferably extends outward in the longitudinal direction than the first absorbent pad. If the second absorbent pad extends outward in the longitudinal direction from the first absorbent pad, the first absorbent pad can be easily removed while the absorbent pad laminate is attached.

  In the absorbent pad laminate of the present invention, a third absorbent pad may be further provided below the second absorbent pad. In this case, it is preferable that the third absorbent pad extends outward from the outer edge of the second absorbent pad, and the second absorbent pad and the third absorbent pad have different colors or patterns. If the absorbent pad laminate is configured as described above, the first absorbent pad, the second absorbent pad, and the third absorbent pad can be easily distinguished from the upper surface side of the absorbent pad laminate. Can do. Therefore, it is possible to easily remove one or more desired absorbent pads depending on the usage state of the absorbent pad. Therefore, even if the absorbent pad laminate is configured as described above, the removal work of the absorbent pad can be easily performed.

  When the absorbent pad laminate has the first to third absorbent pads, the first absorbent pad and the third absorbent pad are white, and the second absorbent pad is preferably colored other than white. . If the absorbent pad laminate is configured in this way, it becomes difficult for the user to feel visually uncomfortable with the absorbent pad laminate, and the first absorbent pad and the third absorbent pad are colored. Since it does not need to give, the manufacturing cost of an absorbent pad laminated body can be held down.

  When the absorbent pad laminate has first to third absorbent pads, the second absorbent pad extends outward in the longitudinal direction from the first absorbent pad, and the third absorbent pad is the second absorbent pad. It is preferable to extend outward in the longitudinal direction from the conductive pad. If each absorbent pad is formed in this manner, the first absorbent pad and the second absorbent pad can be easily removed while the absorbent pad laminate is mounted.

  The absorbent pad has an absorbent body, a top sheet disposed above the absorbent body, and a back sheet disposed below the absorbent body, and at least the back sheet of the second absorbent pad is colored. Preferably it is. If the back sheet is colored among the constituent members of the absorbent pad, when viewed from the upper surface side of the absorbent pad, the colored portion is absorbed by the absorber disposed above the back sheet. It will be limited to the peripheral part. Therefore, it becomes difficult for a user to memorize visual discomfort with respect to the absorbent pad.

  The absorbent pads adjacent to each other are removably joined to each other, and the outer edge of the upper absorbent pad is a portion located inward of the outer edge of the lower absorbent pad, and is joined to the lower absorbent pad. However, a non-bonding region is formed, and the non-bonding region is preferably formed with a depth of 1 mm or more and 10 mm or less from the outer edge of the upper absorbent pad. If a non-bonding region is formed in the outer edge of the absorbent pad and in the vicinity thereof, the outer edge of the upper absorbent pad can be easily picked when the upper absorbent pad is removed from the lower absorbent pad. Become. Therefore, the work which removes an absorptive pad becomes easy in combination with the absorptive pad which adjoins up and down being formed so that it may have a mutually different color or pattern. In addition, since the non-bonded region is not excessively formed, the outer edge of the absorbent pad is not easily lifted and bent.

  The non-bonded region is preferably embossed. If the non-bonded area is embossed, the rigidity of the non-bonded area is increased, and the longitudinal end of the absorbent pad is easily picked, and the longitudinal end of the absorbent pad is not easily bent.

  The present invention is also an absorbent article having a liquid-permeable top sheet, a liquid-impermeable back sheet, and a main absorbent disposed between the top sheet and the top sheet. An absorbent article provided with the absorbent pad laminate is provided. The absorbent article of the present invention is used by appropriately removing one or two or more absorbent pads from the absorbent pad laminate provided on the top surface of the top sheet according to the excretion state of urine and the like from the wearer. be able to. At this time, since each absorbent pad constituting the absorbent pad laminate can be easily discriminated, the absorbent pad to be removed can be easily selected, and the absorbent pad can be easily removed.

  In the absorbent pad laminate of the present invention, the second absorbent pad provided on the lower side extends outward from the outer edge of the first absorbent pad provided on the upper side, and the first absorbent pad and the first absorbent pad Since the two absorbent pads have different colors or patterns, the first absorbent pad and the second absorbent pad can be easily distinguished from the upper surface side of the absorbent pad laminate. Therefore, depending on the use situation of the absorbent pad, the absorbent pad to be removed is selected from the first absorbent pad and the second absorbent pad, and only the first absorbent pad is removed, or the first absorbent pad and It is easy to remove both of the second absorbent pads at once.

The top view which looked at the absorbent pad laminated body of this invention from the surface sheet side is represented. The AA sectional view of the absorptive pad layered product shown in Drawing 1 is expressed.

  The present invention relates to an absorbent pad laminate in which a plurality of absorbent pads are laminated. The absorbent pad laminate of the present invention can be used alone or in combination with separate absorbent articles (for example, disposable diapers and urine pads). In the former case, the absorbent pad laminate is used by being attached to the inner surface of the wearer's underwear (pants), for example. In the latter case, the absorbent pad laminate is used by being placed on the upper surface of a separate absorbent article, for example.

  The absorbent pad constituting the absorbent pad laminate is not particularly limited as long as it includes an absorbent material capable of absorbing excrement such as urine and is formed in a pad shape. The shape (planar shape) of the absorbent pad is not particularly limited. What is necessary is just to determine the shape of an absorptive pad suitably according to a use, for example, substantially rectangular shape, hourglass shape, gourd shape, a battledore shape, etc. are mentioned.

  An absorptive pad has an absorber, a surface sheet distribute | arranged above the absorber, and a back surface sheet | seat distribute | arranged below the absorber. In the absorbent pad laminate, the upper side means the side facing the wearer's skin when the absorbent pad laminate is worn. The lower side means the side opposite to the wearer when wearing the absorbent pad laminate. The longitudinal direction means a direction extending in the front-rear direction of the wearer's crotch when the absorbent pad laminate is mounted. The width direction corresponds to the left and right direction of the wearer when the absorbent pad laminate is mounted.

  The absorber is not particularly limited as long as it includes an absorbent material that can absorb excrement such as urine. As the absorbent body, for example, a molded body obtained by molding the absorbent material into a predetermined shape is used, or the molded body is covered with a covering sheet such as a paper sheet (for example, tissue paper or thin paper) or a liquid-permeable nonwoven sheet. Things can be used. Examples of the absorbent material include hydrophilic fibers such as pulp fibers, and water-absorbing resins such as polyacrylic acid, polyaspartic acid, cellulose, and starch / acrylonitrile. The absorbent material may include polyolefin fibers such as polyethylene and polypropylene, heat-fusible fibers such as polyester fibers such as PET, and polyamide fibers. These heat-fusible fibers may be hydrophilized with a surfactant or the like in order to increase the affinity with urine or the like.

  It is preferable that an absorptive material contains a hydrophilic fiber from the point which improves the absorption speed | rates, such as urine. Moreover, it is preferable that an absorptive material contains a water absorbing resin from the point which raises absorption capacity. Therefore, it is preferable that an absorber contains a hydrophilic fiber (especially pulp fiber) and a water absorbing resin. In this case, it is preferable to use, for example, a mixture of hydrophilic fibers mixed or dispersed in an aggregate of hydrophilic fibers.

  The absorbent body may be a sheet-shaped absorbent body. Examples of the sheet-like absorber include those formed so as to have a water-absorbing resin between liquid-permeable sheets and have no pulp fibers. The sheet-like absorbent body thus formed can be formed thin without being bulky while having a high absorption capacity.

  The shape (planar shape) of the absorber is not particularly limited. The shape of the absorber may be appropriately determined according to the application, and examples thereof include a substantially rectangular shape, an hourglass shape, a gourd shape, and a battledore shape.

  The top sheet is a sheet disposed on the upper side of the absorber, and is preferably liquid permeable. Examples of the surface sheet include nonwoven fabrics formed from hydrophilic fibers such as cellulose, rayon, and cotton; and hydrophobic properties such as polyolefin (for example, polypropylene and polyethylene), polyester (for example, PET), and polyamide (for example, nylon). A non-woven fabric formed from fibers, in which the surface of hydrophobic fibers is hydrophilized with a surfactant, can be used. Moreover, you may use a woven fabric, a knitted fabric, a perforated plastic film etc. as a surface sheet.

  The back sheet is a sheet disposed below the absorber, and may be liquid permeable or liquid impermeable. If the back sheet is liquid permeable, urine can be transferred from the upper absorbent pad to the lower absorbent pad when the absorbent pad laminate is used. Even when used for a long time, leakage of urine and the like is less likely to occur. If the back sheet is liquid-impermeable, when using the absorbent pad laminate, for example, by removing the absorbent pad every time urine is excreted from the wearer, the absorbent pad laminate in a fresh state Can be used. In addition, a back surface sheet | seat may be comprised including a water-soluble film so that it may mention later.

  When the back sheet is liquid permeable, a sheet member usable for the top sheet can be used as the back sheet. When the back sheet is liquid-impermeable, as the back sheet, for example, a nonwoven fabric formed from hydrophobic fibers such as polyolefin (for example, polypropylene, polyethylene), polyester (for example, PET), polyamide (for example, nylon), etc. Alternatively, a plastic film or the like can be used. Moreover, you may use the laminated body of a nonwoven fabric and a plastic film.

  When a nonwoven fabric is used as the topsheet or the backsheet, it is preferable to use a spunbond nonwoven fabric, a point bond nonwoven fabric, an air-through nonwoven fabric, a melt blown nonwoven fabric, an airlaid nonwoven fabric, a spunlace nonwoven fabric, an SMS nonwoven fabric, or the like.

  On the upper surface of the absorbent pad, rising flaps may be provided on both sides in the width direction. By providing the rising flap, side leakage of urine and the like is prevented. The rising flap is formed, for example, by joining a leakproof sheet extending in the longitudinal direction on both sides of the topsheet in the width direction and providing an elastic member inward in the width direction of the leakproof sheet. By providing the leakage preventing sheet and the elastic member in this manner, the inner side in the width direction of the leakage preventing sheet rises toward the wearer's skin by the contraction force of the elastic member, and a rising flap is formed. The rising flap or the leakage preventing sheet is preferably composed of a liquid-impermeable plastic film, a liquid-impermeable nonwoven fabric, or the like.

  As the elastic member provided on the rising flap, an elastic stretchable material used for absorbent articles such as ordinary disposable diapers such as polyurethane yarn, polyurethane film, and natural rubber can be used. The elastic member is preferably fixed in a stretched state with a hot melt adhesive. For example, polyurethane yarn having a fineness of 40 to 1,240 dtex is stretched and arranged at a magnification of 1.1 to 5.0 times and fixed. As the joining means, a rubber-based hot melt adhesive is preferably used. The magnification is 1.0 in the non-expanded state.

  The absorbent pad laminate is formed by laminating a plurality of absorbent pads. When the absorbent pad described above is laminated, in the absorbent pad laminate, the back sheet of the upper absorbent pad and the top sheet of the lower absorbent pad face each other vertically adjacent to the absorbent pad. As described above, a plurality of absorbent pads are laminated.

  The laminated absorbent pads are preferably detachably joined to each other by a known joining means. For example, it is preferable that the laminated absorbent pads are detachably joined to each other by intermittently applied adhesive, pressing (embossing), heat fusion, or the like. The joining means is preferably provided at or near the outer edge of each absorbent pad. For example, the joining means is provided in a region within 30 mm (preferably within 20 mm, more preferably within 10 mm) from the outer edge of each absorbent pad. .

  The lower surface of the absorbent pad laminate, that is, the lower surface of the absorbent pad located at the lowermost side of the absorbent pad laminate is provided with fixing means for attaching to a separate absorbent article or underwear (pants). Also good. Examples of the fixing means include adhesives and hook members of hooks, loops, and fasteners. If fixing means are provided on the lower surface of the absorbent pad laminate, the absorbent pad laminate is absorbed when placed on the upper surface of a separate absorbent article or attached to the inner surface of an undergarment (pants). The adhesive pad laminate can be suitably fixed to a separate absorbent article or undergarment. The absorbent pad laminate may be used by simply placing the absorbent pad laminate on the upper surface of a separate absorbent article without providing a fixing means on the lower surface.

  The number of absorbent pads to be laminated is not particularly limited as long as the absorbent pad laminate is a laminate of a plurality of absorbent pads. The number of absorbent pads to be laminated is preferably 5 or less, and more preferably 4 or less, because the absorbent pad laminate is likely to be easy to handle and wear when the thickness is not too thick. More preferably, 3 or less. In the present invention, the first absorbent pad, the second absorbent pad, the third absorbent pad,...

  When the absorbent pad laminate includes the uppermost first absorbent pad and the second absorbent pad provided below the absorbent pad laminate, the absorbent pad laminate has the first absorbent pad as the first absorbent pad. It is preferable to be provided so as to extend outward from the outer edge of the pad. The first absorbent pad and the second absorbent pad are preferably provided adjacent to each other in the vertical direction. Thus, if the first absorbent pad and the second absorbent pad are provided, it is possible to see both the first absorbent pad and the second absorbent pad from the upper surface side of the absorbent pad laminate. . Therefore, it is possible to remove only the first absorbent pad or to remove both the first absorbent pad and the second absorbent pad at a time according to the use situation of the absorbent pad, and the absorbent pad stack The body can be used in a fresh state.

  For example, when the back sheet of the absorbent pad is liquid permeable, the situation in which only the first absorbent pad is used according to the excretion amount of urine and the like, and the second absorbent pad together with the first absorbent pad The situation used can occur. Therefore, if the absorbent pad to be removed can be easily selected according to the usage state of the absorbent pad, the absorbent pad can be easily removed. Even when the back sheet of the absorbent pad is liquid-impermeable, urine and the like are excreted in large quantities, so that urine overflows from the first absorbent pad and the second absorbent pad also absorbs urine and the like. May be used for Therefore, also in this case, if the absorbent pad to be removed can be easily selected, the work of removing the absorbent pad becomes easier.

  When the absorbent pad laminate has the uppermost first absorbent pad, the second absorbent pad provided below the first absorbent pad, and the third absorbent pad provided further below the first absorbent pad, Preferably, the second absorbent pad extends outward from the outer edge of the first absorbent pad, and the third absorbent pad extends outward from the outer edge of the second absorbent pad. In addition, it is preferable that a 2nd absorbent pad is provided adjacent to a 1st absorbent pad and a 3rd absorbent pad up and down. In this way, if the first absorbent pad, the second absorbent pad, and the third absorbent pad are provided, the first absorbent pad, the second absorbent pad, and the third absorbent from the upper surface side of the absorbent pad laminate. It is possible to see the absorbent pad. Therefore, it is possible to remove one or more desired absorbent pads at a time depending on the usage state of the absorbent pad.

  In other words, in the absorbent pad laminate, it is preferable that the lower absorbent pad adjacent to the upper and lower absorbent pads extend outward from the outer edge of the upper absorbent pad. If the absorbent pad laminate is formed in this way, each absorbent pad can be seen from the upper surface side of the absorbent pad laminate, and a desired absorbent pad can be selected depending on the use situation of the absorbent pad. One or more can be removed at a time.

  In the upper and lower adjacent absorbent pads, the lower absorbent pad only needs to extend outward from at least a part of the outer edge of the upper absorbent pad, but preferably the lower absorbent pad Extends outward in the longitudinal direction from the upper absorbent pad. Specifically, it is preferable that the second absorbent pad extends outward in the longitudinal direction from the first absorbent pad, and the third absorbent pad is outside in the longitudinal direction than the second absorbent pad. It is preferable to extend in the direction. If each absorbent pad is formed in this manner, the wearer or caregiver can easily remove the first absorbent pad or the second absorbent pad with the absorbent pad laminate attached. become.

  When the lower absorbent pad is formed to extend outward in the longitudinal direction from the upper absorbent pad, the relationship between the lengths of the absorbent pads adjacent in the vertical direction in the width direction is The absorbent pad may be formed to have the same length in the width direction as the upper absorbent pad, and the lower absorbent pad is formed to extend outward in the width direction from the upper absorbent pad. It may be. In the former case, it is difficult for urine or the like to overflow from the upper absorbent pad and shift to the lower absorbent pad, and it becomes easier to use the absorbent pad sequentially from the upper absorbent pad. In the latter case, the upper absorbent pad can be easily removed from the end in the width direction. Further, the upper absorbent pad may be formed wider in the width direction than the lower absorbent pad. In this case, it becomes easy to pick only the upper absorbent pad, and the upper absorbent pad. Easy to remove. In the absorbent pad laminate, it is also preferable that the absorbent pads adjacent to each other are formed such that the lower absorbent pad has a larger area than the upper absorbent pad.

  By the way, when laminating a plurality of absorbent pads, it is common to laminate similar absorbent pads. Therefore, for example, the second absorbent pad extends more outward in the longitudinal direction than the first absorbent pad. Even if present, the first absorbent pad and the second absorbent pad may be difficult to distinguish. In particular, the absorbent pad is generally white, and when a plurality of white absorbent pads are stacked, it is difficult to distinguish between the upper absorbent pad and the lower absorbent pad. Therefore, in the absorbent pad laminate of the present invention, the first absorbent pad and the second absorbent pad have different colors or patterns. If the first absorbent pad and the second absorbent pad have different colors or patterns, the first absorbent pad and the second absorbent pad can be easily distinguished, and the absorbent pad to be removed can be easily selected. Can do. Of course, the first absorbent pad and the second absorbent pad may have different patterns of different colors, and “different colors or patterns” excludes different patterns being applied in different colors. It is not a thing. Patterns include patterns, illustrations, symbols, letters, numbers, etc. Solid colors are also a kind of patterns. The handle may be colored.

  When the absorbent pad laminate includes the first to third absorbent pads, the first absorbent pad and the second absorbent pad have different colors or patterns, and the second absorbent pad and the third absorbent pad. It is preferred that the pads have different colors or patterns. If the 1st-3rd absorptive pad is constituted in this way, the 1st absorptive pad, the 2nd absorptive pad, and the 3rd absorptive pad can be distinguished easily, and choose the absorptive pad to remove easily. Can do. In this case, the first absorbent pad and the third absorbent pad may have the same color or pattern, or may have different colors or patterns. In the case where four or more absorbent pads are laminated, it is preferable that the absorbent pads adjacent in the vertical direction are formed so as to have different colors or patterns.

  In the absorbent pad laminate, it is preferable that the first absorbent pad is white and the second absorbent pad is colored other than white. Since the absorbent pad is generally white, if the first absorbent pad that is most noticeable when using the absorbent pad laminate has a white color, the user can visually recognize the absorbent pad laminate. Makes it difficult to remember. Moreover, since it is not necessary to color the 1st absorbent pad, the manufacturing cost of an absorbent pad laminated body can be held down.

  When the absorbent pad laminate has the first to third absorbent pads, the first absorbent pad and the third absorbent pad are white, and the second absorbent pad is colored other than white. preferable. If the absorbent pad laminate is configured in this way, it becomes difficult for the user to feel visually uncomfortable with the absorbent pad laminate, and the first absorbent pad and the third absorbent pad are colored. Since it does not need to give, the manufacturing cost of an absorbent pad laminated body can be held down. When four or more absorbent pads are laminated, it is preferable that the odd-numbered absorbent pads from the top are white and the even-numbered absorbent pads are colored other than white.

  When the absorbent pad is colored other than white, the absorbent pad is preferably colored on the back sheet disposed on the lower side of the absorbent body. Since the top sheet of the absorbent pad is generally composed of a white or colorless thin sheet, even if the back sheet is colored, the color of the back sheet can be visually recognized through the top sheet, but the upper side of the back sheet is absorbed. Since the body is arranged, when the absorbent pad is viewed from the upper surface side, the colored portion of the back sheet is limited to the peripheral portion of the absorbent pad. For this reason, even if the user witnesses the colored absorbent pad, it is difficult to memorize the visual discomfort. Moreover, body fluids such as urine excreted in the absorbent pad can be confirmed in the same manner as in the conventional absorbent pad, and the handleability is excellent. In the absorbent pad laminate, when the first absorbent pad is white and the second absorbent pad is colored, or when the first absorbent pad and the third absorbent pad are white, the second absorbent pad is white. When the absorbent pad is colored other than white, the back sheet of the second absorbent pad may be colored. Accordingly, in the absorbent pad laminate, it is preferable that at least the back sheet of the second absorbent pad is colored.

  It is preferable that the absorbent pads adjacent to each other in the upper and lower sides have different colors or patterns in portions where the absorbent pad laminate is visible when viewed from the upper surface side. Therefore, it is preferable that the absorbent pad which adjoins up and down has a color or a pattern from which the edge of the longitudinal direction or its vicinity has mutually different. For example, the absorbent pads adjacent to each other may be formed such that at least regions within 30 mm (more preferably within 20 mm) from the longitudinal edge of each absorbent pad have different colors or patterns. preferable.

  When the back surface sheet of the absorbent pad is colored, it is preferable that the back sheet is colored in a portion visible through the top sheet when the absorbent pad laminate is viewed from the upper surface side. Therefore, in this case, it is preferable that the back sheet is colored at least partly or entirely within a region within 30 mm (more preferably within 20 mm) from the edge in the longitudinal direction of the absorbent pad. The back sheet to be colored is not particularly limited as long as it is a sheet disposed below the absorber. When a plurality of sheets are disposed below the absorber, at least one of the sheets is colored. It only has to be done.

  The absorbent pad may be colored in a fluorescent color. In particular, if the back sheet is colored in a fluorescent color, even if the top sheet is overlaid on the back sheet, the colored portion of the back sheet is conspicuous and each absorbent pad can be easily identified. Moreover, the absorptive pad may be colored including a light emitting material or a phosphorescent material, so that each absorptive pad can be easily distinguished even in a dark place.

  The absorbent pads adjacent to each other are removably joined to each other, and the outer edge of the upper absorbent pad is a portion located inward of the outer edge of the lower absorbent pad, and is joined to the lower absorbent pad. Instead, it is preferable that a non-bonding region is formed. If a non-bonding region is formed in the outer edge of the absorbent pad and in the vicinity thereof, the outer edge of the upper absorbent pad can be easily picked when the upper absorbent pad is removed from the lower absorbent pad. Become. Therefore, the work which removes an absorptive pad becomes easy in combination with the absorptive pad which adjoins up and down being formed so that it may have a mutually different color or pattern.

  The non-bonding area of the absorbent pad can be worn by removing the absorbent pad easily, and when the absorbent pad laminate is worn, the outer edge of the absorbent pad or its vicinity is bent. It is preferable that it is formed so as not to disturb the person. From this point, it is preferable that the non-bonded region is formed with a depth of 1 mm to 10 mm (more preferably a depth of 2 mm to 8 mm) from the outer edge of the upper absorbent pad. If the non-bonding region is formed in this way, when the upper absorbent pad is removed, the outer edge of the absorbent pad can be easily picked, and the outer edge of the absorbent pad can be lifted and hardly bent.

  The non-bonded region is preferably embossed. If the non-bonded area is embossed, the rigidity of the non-bonded area is increased and the outer edge of the absorbent pad is easily picked. Further, the outer edge of the absorbent pad and the vicinity thereof are not easily bent.

  The embossing of the non-bonded region may be performed while heating, or may be performed simply by pressing without heating. Moreover, the embossing of a non-joining area | region may be provided when joining the laminated absorbent pads mutually so that removal is possible.

  When the lower absorbent pad is formed so as to extend outward in the longitudinal direction from the upper absorbent pad, the non-bonding region should be formed at the longitudinal end of the absorbent pad. Is preferred. If the absorbent pad laminate is configured in this manner, it is easy to pick up the end of the absorbent pad in the longitudinal direction when the absorbent pad is removed, and it is easy to remove the absorbent pad.

  In the absorbent pad laminate of the present invention, the back sheet of the absorbent pad may include a water-soluble film. In this case, the absorbent pad is preferably formed so that the liquid can leak to the outside when the water-soluble film dissolves. In the absorbent pad laminate, for example, the back sheet of the absorbent pad other than the lowermost absorbent pad includes a water-soluble film, and the back sheet of the lower absorbent pad is also water-soluble. You may be comprised including a film. If the absorbent pad is configured as described above, body fluid such as urine excreted from the wearer is absorbed by the absorbent body of the absorbent pad in a state where the water-soluble film is present without being broken. Since a water-soluble film requires a certain amount of time from contact with moisture (that is, body fluid such as urine) until it dissolves, urine or the like excreted initially or first time is absorbed by, for example, the first absorbent pad. . The water-soluble film in contact with urine and the like gradually dissolves until the next excretion, and in the second and subsequent excretion, the urine excreted in the first absorbent pad passes through the back sheet and the 1 It will leak outside the absorbent pad. Urine or the like leaked to the outside of the first absorbent pad is absorbed by the second absorbent pad provided below the first absorbent pad. Therefore, the absorbent capacity of each absorbent pad is fully utilized, and urine or the like overflows from the absorbent pad laminate and hardly leaks sideways.

  Even when the back surface sheet of the absorbent pad is configured to include a water-soluble film, the absorbent pad laminate may appropriately include one or more absorbent pads depending on the state of excretion such as urine from the wearer. Remove and use. For example, if one absorbent pad is removed and used for each excrement from the wearer, the wearer can use the absorbent pad laminate in a fresh state. If a large amount of urine etc. is excreted in the absorbent pad laminate, the urine etc. will be transferred from the upper absorbent pad to the lower absorbent pad as the water-soluble film of the absorbent pad dissolves. Side leakage such as is less likely to occur. When a large amount of urine or the like is excreted in the absorbent pad laminate, two or more absorbent pads may be removed and used at a time according to the usage state of the absorbent pad. At this time, as described above, since an arbitrary absorbent pad can be easily identified, the desired absorbent pad can be easily removed.

  The back sheet may be entirely composed of a water-soluble film, or may be partially composed of a water-soluble film. The water-soluble film may be a known one, and is composed of polyvinyl alcohol, carboxymethyl cellulose, methyl cellulose, hydroxyethyl methyl cellulose, hydroxypropyl methyl cellulose, hydroxypropyl cellulose, polyethylene oxide, polyvinyl pyrrolidone, sodium alginate, gelatin, starch, pullulan and the like. Film can be used. The thickness of the water-soluble film may be appropriately set in consideration of easiness of dissolution. For example, the thickness is preferably 5 μm or more, more preferably 10 μm or more, preferably 100 μm or less, and more preferably 80 μm or less.

  The back sheet may be composed of a liquid-impermeable region and a region that can be leaked by the water-soluble film. For example, by providing a liquid-impermeable region at the center in the longitudinal direction and / or the center in the width direction of the back sheet and making the other areas leakable, urine or the like can easily spread the back sheet in the plane direction. In addition, it becomes possible to more efficiently utilize the absorbent capacity of the absorbent pad. In addition, it is preferable that the area | region in which a back sheet is formed so that leakage is possible occupies 30% or more of the entire area of the back sheet, and more preferably 50% or more. The liquid-impermeable region of the back sheet may be formed by, for example, a liquid-impermeable sheet, or may be formed by subjecting the water-soluble film to water repellency treatment such as silicone processing or fluorine processing.

  The back sheet may be configured by stacking a first back sheet configured to include a water-soluble film and a liquid-permeable second back sheet. In this case, it is preferable that the liquid-permeable second back sheet is overlaid on a region where the first back sheet can be leaked by the water-soluble film. If the liquid-permeable second back sheet is stacked on the water-soluble film of the first back sheet, even if the water-soluble film is melted, the absorbent material contained in the absorbent body is difficult to drop out. Therefore, for example, when urine is excreted in the first absorbent pad, the first absorbent pad is removed and the second absorbent pad under the first absorbent pad is used. The first absorbent pad can be easily removed without care. On the other hand, since the second back sheet is liquid permeable, urine or the like can leak out of the absorbent pad even if the second back sheet is provided. As the second back sheet, a sheet member usable for the top sheet can be used.

  The order of arrangement of the first back sheet and the second back sheet in the vertical direction is not particularly limited. The second back sheet may be provided on the upper side or the lower side of the water-soluble film of the first back sheet.

  For example, if the liquid-permeable second back sheet is provided on the upper side of the water-soluble film of the first back sheet, urine and the like come into contact with the water-soluble film and the water-soluble film dissolves, so that the urine and the like are smooth. It tends to flow out of the absorbent pad. In this case, the melted and dispersed water-soluble film is easily peeled off from the second back sheet, so that only a part of the water-soluble film is melted, so that urine or the like easily passes through the back sheet and smoothly moves to the outside. Accordingly, side leakage of urine or the like hardly occurs in the absorbent pad.

  On the other hand, if the liquid-permeable second back sheet is provided on the lower side of the water-soluble film, the water-soluble film will completely flow out and flow out to the outside through the second back sheet. For example, the water-soluble film partially melted and formed into a lump (gel) in another absorbent pad below it is difficult to migrate. Therefore, after urine is excreted in the absorbent pad, for example, when the first absorbent pad is removed and the second absorbent pad therebelow is used, the water-soluble film is lumped on the upper surface of the second absorbent pad. As a result, it is difficult for the wearer to feel uncomfortable. When the second back sheet is provided on the lower side of the water-soluble film, the water-soluble film may be formed relatively thin from the viewpoint that the water-soluble film dissolves and urine etc. easily leaks to the outside of the absorbent pad. Preferably, the thickness of the water-soluble film is preferably 60 μm or less, for example.

  The second back sheet is preferably provided in a wider range than the absorber. Specifically, the second back sheet is preferably provided so as to extend outward from the entire outer edge of the absorber. Thus, if a 2nd back surface sheet is provided, it will become difficult for the absorptive material contained in an absorber to fall outside.

  As described above, the absorbent pad laminate of the present invention may be colored on the back sheet of the absorbent pad. Therefore, when the back sheet includes a water-soluble film, the back sheet is configured. The water-soluble film may be colored, and the liquid-impermeable sheet or the liquid-permeable second back sheet that forms the liquid-impermeable region may be colored. In addition, as for a back surface sheet, it is preferable that the part which can be visually recognized through a surface sheet sees the absorptive pad laminated body from the upper surface side.

  The absorbent pad laminate of the present invention can be used particularly effectively for excretion care of dementia patients. For example, in the case of a mild dementia patient who is aware of excretion, it is preferable to manage excretion by the patient as much as possible, and when using a urine pad or the like, it is preferable that the patient can replace the pad quickly. In this respect, the absorbent pad laminate of the present invention can be easily replaced by simply removing the absorbent pad, and is easy for the patient to use. For patients with moderate dementia who are not aware of excretion, it is preferable that the caregiver can replace the pad as quickly as possible while ensuring the patient's self-esteem. In this regard, the absorbent pad laminate of the present invention allows the caregiver to easily remove the absorbent pad, and when a large amount of urine is excreted, remove two or more absorbent pads, The absorbent pad laminate can be used in a fresh state. In patients with severe dementia who do not have the concept of excretion, the patient's own cooperation may not be obtained for pad replacement work. In this respect, the absorbent pad laminate of the present invention can be easily absorbed by a caregiver. Can be removed and is effective. In addition, even if the caregiver is unaware of the timing of excretion and the patient excretes multiple times, the absorbent pad is laminated in a fresh state by removing one or more absorbent pads according to the usage situation. The body can be used.

  A configuration example of the absorbent pad laminate of the present invention will be described with reference to FIGS. 1 and 2. 1 and 2 show an example of the absorbent pad laminate of the present invention. FIG. 1 is a plan view of the absorbent pad laminate viewed from the upper surface side, and FIG. 2 is a cross-sectional view taken along line AA of FIG. In the drawing, the arrow x represents the width direction, the arrow y represents the longitudinal direction, and the arrow z represents the vertical direction. The absorbent pad laminate of the present invention is not limited to the embodiment shown in the drawings.

  The absorbent pad laminate 1 is configured by laminating a plurality of absorbent pads 2, and includes an uppermost first absorbent pad 2A, a second absorbent pad 2B provided on the lower side, and It has the 3rd absorptive pad 2C provided in the lower side. Each absorbent pad 2 includes an absorbent body 3, a top sheet 4 disposed on the upper side of the absorbent body 3, and a back sheet 5 disposed on the lower side of the absorbent body 3. The back sheet 5 includes a first back sheet 6 that forms the lower surface of the absorbent pad 2 and a second back sheet 7 disposed between the absorber 3 and the first back sheet 6.

  In the absorbent pad 2, the top sheet 4 is liquid permeable. On the other hand, the back sheet 5 may be liquid permeable or liquid impermeable. For example, the first back sheet 6 may be liquid impermeable and the second back sheet 7 may be liquid permeable (hydrophilic). In this case, diffusion of urine or the like excreted by the absorbent pad 2 in the planar direction is promoted by the second back sheet 7, and leakage from the absorbent pad 2 is prevented by the first back sheet 6. Both the first back sheet 6 and the second back sheet 7 may be liquid permeable. In this case, urine or the like excreted by the absorbent pad 2 is transmitted from the back sheet 5 and another absorption under the urine is absorbed. Will be absorbed by the adhesive pad 2. One of the first back sheet 6 and the second back sheet 7 may be composed of a liquid-permeable sheet and the other may be composed of a water-soluble film. In this case, urine excreted in the absorbent pad 2 is water-soluble. The diffusion in the plane direction is promoted by the film, and the absorption capacity of the absorbent body 3 is fully utilized. After the water-soluble film is melted and broken, urine excreted in the absorbent pad 2 is removed. It penetrates from the back sheet 5 and is absorbed by another absorbent pad 2 below it.

  In the absorbent pad laminate 1, the second absorbent pad 2B extends outward from the outer edge of the first absorbent pad 2A, and the third absorbent pad 2C extends outward from the outer edge of the second absorbent pad 2B. It is extended. Specifically, the second absorbent pad 2B extends outward in the longitudinal direction y from the first absorbent pad 2A, and the third absorbent pad 2C extends in the longitudinal direction y from the second absorbent pad 2B. It extends outward. The first absorbent pad 2A and the second absorbent pad 2B have different colors or patterns, and the second absorbent pad 2B and the third absorbent pad 2C have different colors or patterns. Since the absorbent pad laminate 1 is configured in this way, when the absorbent pad laminate 1 is viewed from the upper surface side, each absorbent pad 2A, 2B, 2C can be easily distinguished, and the desired absorbent pad 2 can be easily removed.

  It is preferable that the absorbent pad 2 which adjoins up and down has the color or pattern from which the back sheet 5 mutually differs. As the back sheet 5, the first back sheet 6 may have a different color or pattern, and the second back sheet 7 may have a different color or pattern.

  As shown in FIG. 2, the absorbent pads 2 adjacent to each other in the vertical direction are detachably joined to each other by the joining means 8 and are not attached to the end in the longitudinal direction y (the outer portion in the longitudinal direction y than the joining means 8). A junction region is formed. In FIG. 2, the first absorbent pad 2A and the second absorbent pad 2B below the first absorbent pad 2A and the second absorbent pad 2B are respectively disposed at the ends in the longitudinal direction y (predetermined regions from the edges in the longitudinal direction y) of the lower surfaces. A non-bonding region that is not bonded to the third absorbent pad 2C is formed. If the non-bonded regions are formed at the ends in the longitudinal direction y of the first absorbent pad 2A and the second absorbent pad 2B, when removing the first absorbent pad 2A and the second absorbent pad 2B, It becomes easy to pick the end portion in the longitudinal direction y, and the removal work of the absorbent pad 2 becomes easy.

  Next, the absorbent article of the present invention will be described. The absorbent article of the present invention has a liquid-permeable top sheet, a liquid-impermeable back sheet, and a main absorbent body disposed therebetween, and the absorbent pad laminate of the present invention is the top. It is provided on the upper surface of the sheet. A typical example of the absorbent article is a disposable diaper. The absorbent article of the present invention can be worn in the same manner as a general absorbent article, and the same effect as the absorbent pad laminate of the present invention can be obtained.

  When the absorbent article is a disposable diaper, the disposable diaper includes, for example, a front side portion, a rear side portion, and a crotch portion that is located between them and includes a main absorbent body. The disposable diaper includes, for example, a laminated body in which a main absorbent body is disposed between a top sheet and a back sheet on a crotch part of a pants member having a front side part, a rear side part, and a crotch part positioned therebetween. Configured. The disposable diaper may also be formed in a pants shape in which a laminate in which a main absorbent body is disposed between a top sheet and a back sheet has a front side part, a rear side part, and a crotch part positioned therebetween. Good.

  The front side portion corresponds to a portion applied to the wearer's belly side when wearing the disposable diaper, and the rear side portion corresponds to a portion applied to the wearer's back side when wearing the disposable diaper. A crotch part is located between a front side part and a rear side part, and is equivalent to the part applied to a wearer's crotch.

  A disposable diaper is an open type (tape type) disposable diaper that is provided with a pair of fastening members at the left and right ends of the rear side part and is formed into a pants shape when worn by the fastening member. It may be a pants-type disposable diaper in which a waist opening and a pair of leg openings are formed by joining the side parts.

  The top sheet is a sheet positioned on the wearer side when wearing the absorbent article. The top sheet is liquid permeable, and a sheet usable as the top sheet can be used.

  The back sheet is a sheet that is located on the opposite side, that is, outside, of the wearer when the absorbent article is worn. The back sheet is liquid-impermeable, and a sheet usable for the liquid-impermeable back sheet can be used.

  As the main absorbent body, the absorbent body of the absorbent pad described above can be used. In addition, the absorbent material used for the main absorbent body of the absorbent article and the absorbent material used for the absorbent body of the absorbent pad may be the same or different. The shape of the main absorbent body is not particularly limited.

  The main absorbent body of the absorbent article preferably has a larger basis weight (mass per unit area) than the absorbent body of each absorbent pad constituting the absorbent pad laminate. By forming the basis weight of the main absorbent body of the absorbent article to be relatively large, it becomes easy to prevent urine etc. from leaking from the absorbent article even if a large amount of urine is excreted.

  The absorbent article is preferably provided with rising flaps on both sides in the width direction of the top sheet. By providing the rising flap, side leakage of urine and the like is prevented. Moreover, by providing the rising flap, it becomes easy to stably place the absorbent pad laminate between them. The rising flap is formed, for example, by joining side sheets extending in the longitudinal direction on both sides in the width direction of the top sheet and providing an elastic member inward in the width direction of the side sheet. The rising flap or the side sheet is preferably composed of a liquid-impermeable plastic film, a liquid-impermeable nonwoven fabric, or the like.
