Description

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

  BACKGROUND Conventionally, there is known an absorbent pad laminate in which a plurality of absorbent pads for containing excrement such as urine are stacked. Such an absorbent pad laminate is excellent in handling, since new absorbent pads can be used by removing the absorbent pads sequentially from the top without replacing the pads themselves. 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 smaller.

JP 2011-72335 A

  The absorbent pad laminate is used by removing the absorbent pad in order from the top, but in the state where the absorbent pad laminate is attached between the crotch of the wearer, the work of removing the absorbent pad tends to be difficult. In addition, depending on the use condition of the absorbent pad, it may be desirable to remove two or more absorbent pads at a time, but in the conventional absorbent pad laminate, one absorbent pad is sequentially arranged from the top It needs to be removed, and the removal operation tends to be troublesome.

  The present invention has been made in view of the above-mentioned circumstances, and an object thereof is an absorbent pad laminate which can easily discriminate any absorbent pad and can easily remove one or more absorbent pads. It is an object of the present invention to provide an absorbent article comprising a body and the absorbent pad laminate.

  The absorbent pad laminate of the present invention, which was able to solve the above-mentioned problems, has a plurality of absorbent pads laminated, and the uppermost first absorbent pad and the second absorbent provided on the lower side thereof. 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 a feature in having the According to the absorbent pad laminate of the present invention, the first absorbent pad and the second absorbent pad can be easily distinguished when viewed from the top side, so that the first absorbent pad and the second absorbent pad can be selected according to the usage condition of the absorbent pad. (2) It is easy to select an absorbent pad to be removed from among the absorbent pads and to remove only the first absorbent pad or to remove both the first absorbent pad and the second absorbent pad at one time. Therefore, the absorbent pad can be easily removed, and by removing the desired absorbent pad, it is possible to use the absorbent pad laminate in a fresh state.

  Preferably, the first absorbent pad is white and the second absorbent pad is colored other than white. Because the absorbent pad is generally white, it is possible for the user to visually identify the absorbent pad laminate if the first absorbent pad that is most noticeable when using the absorbent pad laminate has a white color. It becomes difficult to feel a sense of discomfort. In addition, since it is not necessary to color the first absorbent pad, the manufacturing cost of the absorbent pad laminate can be reduced.

  Preferably, the second absorbent pad extends outwardly in the longitudinal direction than the first absorbent pad. If the second absorbent pad extends outward in the longitudinal direction more than the first absorbent pad, the first absorbent pad can be easily removed with the absorbent pad laminate 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, the third absorbent pad preferably extends outward from the outer edge of the second absorbent pad, and the second absorbent pad and the third absorbent pad preferably have different colors or patterns. If the absorbent pad laminate is configured in this manner, the first absorbent pad, the second absorbent pad, and the third absorbent pad can be easily distinguished as viewed from the upper surface side of the absorbent pad laminate. Can. Therefore, it is possible to easily remove one or more desired absorbent pads depending on the usage of the absorbent pad. Therefore, even if the absorbent pad laminate is configured as described above, the absorbent pad can be removed easily.

  When the absorbent pad laminate has the first to third absorbent pads, it is preferable that the first absorbent pad and the third absorbent pad be white, and the second absorbent pad be colored other than white. . When the absorbent pad laminate is configured as described above, it is difficult for the user to feel a sense of visual discomfort with respect to the absorbent pad laminate, and the first absorbent pad and the third absorbent pad are colored. Since it does not need to be applied, the manufacturing cost of the absorbent pad laminate can be reduced.

  When the absorbent pad laminate includes the first to third absorbent pads, the second absorbent pad extends outward in the longitudinal direction than the first absorbent pad, and the third absorbent pad has a second absorbent pad. It is preferable to extend outward in the longitudinal direction than the elastic pad. If each absorbent pad is formed as described above, it is possible to easily remove the first absorbent pad and the second absorbent pad with the absorbent pad laminate attached.

  The absorbent pad has an absorbent body, a top sheet disposed on the upper side of the absorbent body, and a back sheet disposed on the lower side of the absorbent body, and at least the back sheet of the second absorbent pad is colored Is preferred. If the back sheet is colored among the constituent members of the absorbent pad, the part colored by the absorber disposed on the upper side of the back sheet when viewed from the upper surface side of the absorbent pad is the absorbent pad Is limited to the peripheral portion of the Therefore, it is difficult for the user to feel a sense of visual discomfort with the absorbent pad.

  The upper and lower adjacent absorbent pads are releasably joined to each other, and the outer edge of the upper absorbent pad is in contact with the lower absorbent pad at a portion located inwardly of the outer edge of the lower absorbent pad. It is preferable that a non-joined area is formed without being formed, and the non-joined area is formed at a depth of 1 mm or more and 10 mm or less from the outer edge of the upper absorbent pad. Thus, when the non-bonded area is formed at the outer edge of the absorbent pad and in the vicinity thereof, when removing the upper absorbent pad from the lower absorbent pad, it is easy to pick the outer edge of the upper absorbent pad Become. As a result, combined with the upper and lower adjacent absorbent pads being formed to have different colors or patterns, the task of removing the absorbent pad is facilitated. In addition, since the non-bonded area is not excessively formed, the outer edge of the absorbent pad is less likely to be lifted and bent.

  The non-bonded area is preferably embossed. If the non-joining area is embossed, the rigidity of the non-joining area is increased, and the longitudinal end of the absorbent pad can be easily grasped, and the longitudinal end of the absorbent pad is less likely to be bent.

  The present invention is also an absorbent article having a liquid-permeable top sheet, a liquid-impermeable back sheet, and a main absorbent body disposed therebetween, and the present invention is applied to the upper surface of the top sheet. An absorbent article provided with the absorbent pad laminate. 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 situation such as urine from the wearer. be able to. Under the present circumstances, since each absorptive pad which comprises an absorptive pad laminated body can be discriminate | determined easily, the absorptive pad to remove can be selected easily and the removal operation of an absorptive pad can be performed now easily.

  According to 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 (2) Since the absorbent pads have different colors or patterns, it is possible to easily distinguish the first absorbent pad from the second absorbent pad when viewed from the upper surface side of the absorbent pad laminate. Therefore, according to the use condition 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 one time.

The top view which looked at the absorptive pad laminated body of this invention from the surface sheet side is represented. FIG. 7 shows an AA cross section of the absorbent pad laminate shown in FIG. 1.

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

  The absorptive pad which comprises an absorptive pad laminated body contains the absorptive material which can absorb excretion, such as urine, and if it is formed in pad shape, it will not be specifically limited. The shape (planar shape) of the absorbent pad is not particularly limited. The shape of the absorbent pad may be appropriately determined according to the application, and examples thereof include a substantially rectangular shape, an hourglass shape, a gourd shape, and a wing plate shape.

  The absorbent pad has, for example, an absorbent, a top sheet disposed on the upper side of the absorbent, and a back sheet disposed on the lower side of the absorbent. In the absorbent pad laminate, the upper side means the side facing the wearer's skin when the absorbent pad laminate is attached. 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 crotch of the wearer when the absorbent pad laminate is attached. The width direction corresponds to the left-right direction of the wearer when wearing the absorbent pad laminate.

  The absorber is not particularly limited as long as it contains an absorbent material capable of absorbing excrement such as urine. As the absorber, for example, a molded body obtained by forming an 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. The thing can be used. Examples of the absorbent material include hydrophilic fibers such as pulp fibers, and water-absorbent resins such as polyacrylic acid-based, polyaspartic acid-based, cellulose-based and starch / acrylonitrile-based. In addition, the absorbent material may include polyolefin fibers such as polyethylene and polypropylene, polyester fibers such as PET, and heat fusible fibers such as polyamide fibers. These heat fusible fibers may be subjected to a hydrophilization treatment with a surfactant or the like in order to enhance affinity with urine or the like.

  The absorbent material preferably contains a hydrophilic fiber in order to increase the absorption rate of urine or the like. In addition, from the viewpoint of enhancing the absorption capacity, the absorbent material preferably contains a water absorbing resin. Therefore, the absorber preferably contains hydrophilic fibers (in particular, pulp fibers) and a water absorbing resin. In this case, it is preferable to use, for example, a mixture of or dispersed with a water absorbent resin in an aggregate of hydrophilic fibers.

  The absorber may be a sheet-like absorber. As a sheet-like absorber, what was formed so that it may have a water absorbing resin between liquid-permeable sheets and may not have a pulp fiber may be mentioned. The sheet-like absorbent body thus formed can be formed thin and not 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 wing plate shape.

  The surface sheet is a sheet disposed on the upper side of the absorber, and is preferably liquid-permeable. The surface sheet is, for example, non-woven fabric made of hydrophilic fibers such as cellulose, rayon and cotton; and hydrophobicity 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 a hydrophobic fiber is made hydrophilic with a surfactant, or the like 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 under the absorber, and may be liquid permeable or liquid impermeable. If the back sheet is liquid-permeable, urine and the like can be transferred from the upper absorbent pad to the lower absorbent pad when the absorbent pad laminate is used, and the absorbent pad laminate is elongated Even when used for a while, it is difficult for leakage of urine and the like 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 or the like is excreted from the wearer, the absorbent pad laminate in a fresh state It is possible to use In addition, a back surface sheet may be comprised including a water-soluble film so that it may mention later.

  When the backsheet is liquid-permeable, a sheet member usable for the topsheet can be used as the backsheet. When the back sheet is liquid impermeable, a non-woven fabric formed from hydrophobic fibers such as, for example, polyolefin (for example, polypropylene, polyethylene), polyester (for example, PET), polyamide (for example, nylon) as the back sheet Or, 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 using a non-woven fabric as the top sheet or the back sheet, it is preferable to use a spun bond non-woven fabric, a point bond non-woven fabric, an air through non-woven fabric, a meltblown non-woven fabric, an air laid non-woven fabric, a spun lace non-woven fabric, an SMS non-woven fabric, etc.

  The upper surface of the absorbent pad may be provided with rising flaps on both sides in the width direction. By providing the rising flaps, side leakage such as urine is prevented. The rising flaps are formed, for example, by joining longitudinally extending leakproof sheets on both sides in the width direction of the surface sheet, and providing an elastic member inward in the width direction of the leakproof sheets. By providing the leakproof sheet and the elastic member in this manner, the inward in the width direction of the leakproof 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 leakproof sheet is preferably made of a liquid impermeable plastic film, a liquid impermeable nonwoven, or the like.

  As an elastic member provided in a standup flap, elastic elastic material used for absorbent articles, such as usual disposable diapers, such as polyurethane thread, a polyurethane film, and natural rubber, can be used. The elastic member is preferably fixed with a hot melt adhesive in a stretched state. For example, a polyurethane yarn having a fineness of 40 to 1,240 dtex is stretched and disposed at a magnification of 1.1 to 5.0 times and fixed. As a joining means, preferably, a rubber-based hot melt adhesive is used. In addition, the said magnification makes an unexpanded state 1.0 time.

  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 absorbent pad on the upper side of the absorbent pad adjacent to the top and bottom faces the surface sheet of the lower absorbent pad. As such, a plurality of absorbent pads are stacked.

  The laminated absorbent pads are preferably releasably joined to one another by known joining means. For example, the laminated absorbent pads are preferably releasably joined to each other by an intermittently applied adhesive, pressing (emboss), heat fusion or the like. The bonding means is preferably provided at or near the outer edge of each absorbent pad, for example, provided in an area 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 on the lowermost side of the absorbent pad laminate, is provided with fixing means for attaching to a separate absorbent article or underwear (pants) It is also good. The fixing means may, for example, be an adhesive or a hook member of a hook / loop fastener. If fixing means are provided on the lower surface of the absorbent pad laminate, the absorbent pad laminate is absorbed when it is mounted on the upper surface of a separate absorbent article or attached to the inner surface of underwear (pants) The elastic pad laminate can be suitably fixed to a separate absorbent article or underwear. In addition, a fixing means is not provided in a lower surface, but an absorbent pad laminated body may be simply mounted and used on the upper surface of another absorbent article.

  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 the absorbent pads to be laminated is preferably 5 or less, more preferably 4 or less, since the absorbent pad laminate tends to be easy to handle and wear when the thickness is not too large. And three or less are more preferable. In the present invention, the first absorbent pad, the second absorbent pad, the third absorbent pad, and so on are referred to in order from the uppermost absorbent pad to the lower side.

  In the case where the absorbent pad laminate has the uppermost first absorbent pad and the second absorbent pad provided on the lower side, the absorbent pad laminate has the second absorbent pad as the first absorbent. It is preferable to extend outward from the outer edge of the pad. Preferably, the first absorbent pad and the second absorbent pad are provided vertically adjacent to each other. Thus, if the first absorbent pad and the second absorbent pad are provided, it becomes 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 one time, depending on the use condition of the absorbent pad, and it is possible to laminate absorbent pads. You will be able to use your body fresh.

  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 amount of excretion such as urine, and the second absorbent pad together with the first absorbent pad The situation in which it is used can occur. Therefore, if the absorbent pad to be removed can be easily selected according to the use condition of the absorbent pad, the absorbent pad can be easily removed. Even if the back sheet of the absorbent pad is liquid impermeable, urine and the like are excreted from the first absorbent pad by excreting a large amount of urine and the like, and the second absorbent pad also absorbs urine and the like. It may happen to be used for Therefore, in this case as well, if it is possible to easily select the absorbent pad to be removed, the task of removing the absorbent pad is facilitated.

  When the absorbent pad laminate has the uppermost first absorbent pad, the second absorbent pad provided on the lower side, and the third absorbent pad provided on the lower side, 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. Preferably, the second absorbent pad is provided vertically adjacent to the first absorbent pad and the third absorbent pad. Thus, 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 pad from the upper surface side of the absorbent pad laminate. It is possible to see the absorbent pad. Thus, depending on the use of the absorbent pad, it is possible to remove one or more desired absorbent pads at a time.

  That is, in the absorbent pad laminate, it is preferable that the absorbent pads below the absorbent pads adjacent above and below be formed to extend outward from the outer edge of the upper absorbent pad. If the absorbent pad laminate is formed in this manner, each absorbent pad can be seen from the upper surface side of the absorbent pad laminate, and a desired absorbent pad can be obtained according to the usage condition of the absorbent pad. It is possible to remove one or more at a time.

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

  When the lower absorbent pad is formed to extend outward in the longitudinal direction more than the upper absorbent pad, the lower in the width direction of the absorbent pads adjacent to the upper and lower sides, 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 than the upper absorbent pad. It may be In the former case, urine or the like overflows from the upper absorbent pad and becomes less likely to migrate to the lower absorbent pad, and it becomes easier to sequentially use the absorbent pads from the upper absorbent pad. In the latter case, the upper absorbent pad can be easily removed from the widthwise end. Also, the upper absorbent pad may be formed wider in the width direction than the lower absorbent pad, in which case it is easy to pick only the upper absorbent pad, and the upper absorbent pad It becomes easy to remove. In the absorbent pad laminate, it is also preferable that upper and lower adjacent absorbent pads be formed so that the lower absorbent pad has a wider area than the upper absorbent pad.

  By the way, when laminating a plurality of absorbent pads, it is common to laminate similar absorbent pads, so that, for example, the second absorbent pad extends outward in the longitudinal direction than the first absorbent pad. Even if the first absorbent pad and the second absorbent pad may be difficult to distinguish. In particular, the absorbent pads are generally white, and when a plurality of white absorbent pads overlap, it tends to be difficult to distinguish the upper absorbent pad from the lower absorbent pad. Therefore, in the absorbent pad laminate of the present invention, the first absorbent pad and the second absorbent pad are made to have different colors or patterns. If the first absorbent pad and the second absorbent pad have different colors or patterns, it is easy to distinguish between the first absorbent pad and the second absorbent pad, and easily select the absorbent pad to be removed. Can. Of course, the first absorbent pad and the second absorbent pad may have different patterns different in color from each other, and "different colors or patterns" excludes different patterns being applied in different colors. It is not a thing. The pattern includes a pattern, an illustration, a symbol, a letter, a number, etc., and a plain color is also a kind of pattern. 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 It is preferred that the pads have different colors or patterns from one another. Thus, if the first to third absorbent pads are configured, the first absorbent pad, the second absorbent pad, and the third absorbent pad can be easily distinguished, and the absorbent pads to be removed can be easily selected. Can. 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. When the absorbent pad laminate is a laminate of four or more absorbent pads, it is preferable that upper and lower adjacent absorbent pads be formed 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. Because the absorbent pad is generally white, it is possible for the user to visually identify the absorbent pad laminate if the first absorbent pad that is most noticeable when using the absorbent pad laminate has a white color. Makes it difficult to feel uncomfortable. In addition, since it is not necessary to color the first absorbent pad, the manufacturing cost of the absorbent pad laminate can be reduced.

  When the absorbent pad laminate includes 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. When the absorbent pad laminate is configured as described above, it is difficult for the user to feel a sense of visual discomfort with respect to the absorbent pad laminate, and the first absorbent pad and the third absorbent pad are colored. Since it does not need to be applied, the manufacturing cost of the absorbent pad laminate can be reduced. When four or more absorbent pads are laminated, it is preferable that the odd-numbered absorbent pads from the top be white, and the even-numbered absorbent pads be colored other than white.

  When the absorbent pad is colored other than white, it is preferable that the absorbent pad be colored in the back sheet disposed on the lower side of the absorbent. 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 absorbs it. Since the body is disposed, when the absorbent pad is viewed from the upper surface side, the colored part of the back sheet is limited to the peripheral part of the absorbent pad. Therefore, even when the user sees the colored absorbent pad, it is difficult to feel visual discomfort. Further, the body fluid such as urine excreted in the absorbent pad can be confirmed in the same manner as the conventional absorbent pad, and the handling property is excellent. When the first absorbent pad is white and the second absorbent pad is colored, the first absorbent pad and the third absorbent pad are white, and the second absorbent pad is used as the second absorbent pad laminate. When the absorbent pad is colored other than white, the back sheet of the second absorbent pad may be colored. Therefore, in the absorbent pad laminate, it is preferable that at least the back sheet of the second absorbent pad be colored.

  In the upper and lower adjacent absorbent pads, it is preferable that the visible parts of the absorbent pad laminate viewed from the top have different colors or patterns. Therefore, it is preferable that the absorbent pads adjacent above and below have different colors or patterns at least at or near the longitudinal edges. For example, upper and lower adjacent absorbent pads 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 from one another. preferable.

  When the back 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 top side. Therefore, in this case, it is preferable that a part or all of the area within 30 mm (more preferably within 20 mm) at least from the longitudinal edge of the absorbent pad is colored. The back sheet to be colored is not particularly limited as long as it is a sheet disposed on the lower side of the absorber, and in the case where a plurality of sheets are arranged on the lower side of the absorber, at least one of them is colored It should be done.

  The absorbent pad may be colored in a fluorescent color. In particular, if the back surface sheet is colored in fluorescent color, even if the top surface sheet is superimposed thereon, the colored portions of the back surface sheet are noticeable, and each absorbent pad can be easily identified. In addition, the absorbent pad may be colored including a light emitting material and a luminous material, whereby each absorbent pad can be easily identified even in a dark place.

  The upper and lower adjacent absorbent pads are releasably joined to each other, and the outer edge of the upper absorbent pad is in contact with the lower absorbent pad at a portion located inwardly of the outer edge of the lower absorbent pad. Preferably, a non-junction region is formed. Thus, when the non-bonded area is formed at the outer edge of the absorbent pad and in the vicinity thereof, when removing the upper absorbent pad from the lower absorbent pad, it is easy to pick the outer edge of the upper absorbent pad Become. As a result, combined with the upper and lower adjacent absorbent pads being formed to have different colors or patterns, the task of removing the absorbent pad is facilitated.

  In the non-bonding area of the absorbent pad, the absorbent pad can be easily removed, and when the absorbent pad laminate is worn, the outer edge of the absorbent pad or the vicinity thereof is bent or the like. It is preferable that it is formed so as not to disturb the person. From this point of view, it is preferable that the non-bonding area be formed at a depth of 1 mm or more and 10 mm or less (more preferably, a depth of 2 mm or more and 8 mm or less) from the outer edge of the upper absorbent pad. If the non-bonding area is formed in this way, when removing the upper absorbent pad, the outer edge of the absorbent pad can be easily grasped, and the outer edge of the absorbent pad can not be lifted and bent.

  The non-bonded area 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 can be easily grasped. In addition, the outer edge of the absorbent pad and the vicinity thereof become difficult to bend.

  The embossing of the non-joining area may be pressing while heating, or may be simple pressing without heating. Also, the embossing of the non-joining area may be provided when the laminated absorbent pads are removably joined together.

  If the lower absorbent pad is formed to extend longitudinally outward more than the upper absorbent pad, the non-bonded area should be formed at the longitudinal end of the absorbent pad Is preferred. When the absorbent pad laminate is configured as described above, when removing the absorbent pad, the longitudinal end of the absorbent pad can be easily grasped, and the absorbent pad can be easily removed.

  In the absorbent pad laminate of the present invention, the back sheet of the absorbent pad may comprise a water-soluble film. In this case, it is preferable that the absorbent pad is formed so that the liquid can leak to the outside when the water-soluble film is dissolved. In the absorbent pad laminate, for example, the back sheet of the absorbent pad other than at least the lowermost absorbent pad includes a water-soluble film, and the back sheet of the lowermost absorbent pad is also water-soluble. It may be configured to include a film. If the absorbent pad is configured as described above, in the state where the water-soluble film is present without breaking, a body fluid such as urine excreted from the wearer is absorbed by the absorbent pad absorbent body. The water-soluble film takes a certain time to dissolve after being in contact with water (i.e., body fluid such as urine), so urine excreted initially or at the first time is absorbed by, for example, the first absorbent pad . Then, the water-soluble film in contact with urine etc. gradually dissolves until the next excretion, and in the second and subsequent excretion, urine etc. excreted in the first absorbent pad passes through the back sheet and 1 It will leak to the outside of the absorbent pad. Urine etc. which leaked out of the 1st absorptive pad are absorbed by the 2nd absorptive pad provided in the lower side. Therefore, while the absorption capacity of each absorptive pad is fully utilized, it also becomes difficult to happen that urine etc. overflow from an absorptive pad laminated body and a side leak.

  Even when the back sheet of the absorbent pad is configured to include a water-soluble film, the absorbent pad laminate suitably has one or two or more absorbent pads according to the excretion status of urine and the like from the wearer. You may remove and use. For example, if the absorbent pad is removed and used one by one every time the wearer's excrement is used, the wearer can use the absorbent pad laminate in a fresh state. When a large amount of urine or the like is excreted in the absorbent pad laminate, the water-soluble film of the absorbent pad dissolves, whereby urine or the like sequentially shifts from the upper absorbent pad to the lower absorbent pad. Side leakage such as is also 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 at one time depending on the usage of the absorbent pad. At this time, as described above, since any absorbent pad can be easily identified, a 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 made of polyvinyl alcohol, carboxymethyl cellulose, methyl cellulose, hydroxyethyl methyl cellulose, hydroxypropyl methyl cellulose, hydroxypropyl cellulose, polyethylene oxide, polyvinyl pyrrolidone, sodium alginate, gelatin, starch, pullulan, etc. Film can be used. The thickness of the water-soluble film may be appropriately set in consideration of ease of dissolution, and is preferably 5 μm or more, more preferably 10 μm or more, and preferably 100 μm or less, and more preferably 80 μm or less.

  The back sheet may be composed of a liquid impermeable area and an area which can be leaked by a water soluble film. For example, by providing the liquid impermeable area in the longitudinal central part and / or the central part in the width direction of the back sheet, and making the other areas leakable, it is easy for urine etc. to spread in the plane direction of the back sheet. It is possible to utilize the absorption capacity of the absorbent pad more efficiently. In addition, it is preferable that the area | region in which a back surface sheet is formed so that leakage may occupy 30% or more of the whole area of a back surface sheet, and it is more preferable to occupy 50% or more. The liquid impermeable area of the back sheet may be formed of, for example, a liquid impermeable sheet, or may be formed by subjecting a water-soluble film to a water repelling treatment such as silicone processing or fluorine processing.

  The back sheet may be configured by overlapping a first back sheet including a water-soluble film and a liquid-permeable second back sheet. In this case, it is preferable that the liquid-permeable second back sheet be superimposed on the area where the first back sheet can be leaked by the water-soluble film. If the liquid-permeable second back sheet is superimposed on the water-soluble film of the first back sheet, even if the water-soluble film is melted, the absorbent material contained in the absorber is unlikely to fall out. Therefore, for example, when urine or the like is excreted into the first absorbent pad, the first absorbent pad is removed and the second absorbent pad under the first absorbent pad is used, etc. The first absorbent pad can be easily removed without taking care. On the other hand, since the second backsheet is liquid-permeable, urine and the like can leak to the outside of the absorbent pad even if the second backsheet is provided. As the second back sheet, a sheet member usable for the top sheet can be used.

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

  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 melts, whereby the urine and the like become smooth. It is easy to flow out of the absorbent pad. In this case, since the water-soluble film which has been melted and dispersed is easily peeled off from the second back sheet, urine and the like easily pass through the back sheet and are easily transferred to the outside simply by melting a part of the water-soluble film. Accordingly, side leakage such as urine is less likely to occur 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 completely dissolved water-soluble film passes through the second back sheet and flows out to the outside, For example, the water-soluble film which has been partially dissolved and lumped (gelled) is less likely to migrate to another absorbent pad below it. Therefore, after urine or the like is excreted in the absorbent pad, for example, when using the second absorbent pad below by removing the first absorbent pad, the water-soluble film lumps on the upper surface of the second absorbent pad As it becomes difficult to exist, it becomes difficult for the wearer to feel discomfort. When the second back sheet is provided on the lower side of the water-soluble film, the water-soluble film is formed relatively thin in that the water-soluble film melts and urine and the like are easily leaked to the outside of the absorbent pad. Preferably, the thickness of the water-soluble film is, for example, 60 μm or less.

  The second back sheet is preferably provided in a wider range than the absorber. Specifically, the second back sheet is preferably provided to extend outward beyond the entire outer edge of the absorber. When the second back sheet is provided as described above, the absorbent material contained in the absorber is unlikely to be dropped out.

  In the absorbent pad laminate of the present invention, as described above, since the back sheet of the absorbent pad may be colored, when the back sheet includes a water-soluble film, the back sheet is constituted. The water-soluble film to be formed may be colored, or the liquid impermeable sheet forming the liquid impermeable area or the liquid-permeable second back sheet may be colored. In the back sheet, it is preferable that a portion visible through the top sheet be colored when the absorbent pad laminate is viewed from the top side.

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

  The structural example of the absorptive pad laminated body of this invention is demonstrated with reference to FIG. 1 and FIG. 1 and 2 show an example of the absorbent pad laminate of the present invention.

  In the absorbent pad 2, the top sheet 4 is liquid permeable. On the other hand, 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 and the like excreted in 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 which case urine excreted in the absorbent pad 2 is transmitted from the back sheet 5 and another absorption therebelow is absorbed. It will be absorbed by the sex pad 2. One of the first back sheet 6 and the second back sheet 7 may be formed of a liquid-permeable sheet and the other may be formed of a water-soluble film. In this case, the urine excreted in the absorbent pad 2 is water-soluble The film promotes diffusion in the planar direction to fully utilize the absorption capacity of the absorber 3, and after the water-soluble film is dissolved and broken, urine etc. excreted in the absorbent pad 2 It permeate | transmits from the back surface sheet 5, and will be absorbed by the another absorptive pad 2 of the lower part.

  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 than the first absorbent pad 2A, and the third absorbent pad 2C extends in the longitudinal direction y relative to the second absorbent pad 2B. It extends outward. And the 1st absorptive pad 2A and the 2nd absorptive pad 2B have mutually different color or pattern, and the 2nd absorptive pad 2B and the 3rd absorptive pad 2C have mutually different color or pattern. Since the absorbent pad laminate 1 is configured as described above, when the absorbent pad laminate 1 is viewed from the upper surface side, each absorbent pad 2A, 2B, 2C can be easily distinguished, and a desired absorbent pad is obtained. 2 can be removed easily.

  In the absorbent pads 2 adjacent to the top and bottom, it is preferable that the back sheet 5 have different colors or patterns. As the backsheet 5, the first backsheet 6 may have different colors or patterns, and the second backsheet 7 may have different colors or patterns.

  Upper and lower adjacent absorbent pads 2 are releasably joined to each other by joining means 8 as shown in FIG. 2 and are not connected to the end in the longitudinal direction y (outward portion in the longitudinal direction y than joining means 8). A junction area is formed. In FIG. 2, the lower end of the second absorbent pad 2B is provided at the end in the longitudinal direction y (a predetermined area from the edge of the longitudinal direction y) of the lower surface of the first absorbent pad 2A and the second absorbent pad 2B. And a non-joining area which is not joined to the third absorbent pad 2C. If non-bonded areas are respectively formed at the end portions 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, The end portion in the longitudinal direction y can be easily grasped, and the absorbent pad 2 can be easily removed.
