Description

TECHNICAL AREA

[0001] The present invention relates to an absorbent auxiliary article that is used in combination with an absorbent article, such as a urine pad and a disposable diaper. TECHNICAL BACKGROUND

[0002] Absorbent auxiliary articles are commonly known to be attached to the side of an absorbent article facing the skin surface in order to increase the absorption capacity of the absorbent article or to improve leakage protection (see, for example, patent literature 1 to 3). LIST OF REFERENCE PATENT LITERATURE PATENT LITERATURE 1 Japanese Unexamined Patent Disclosure Publication Number H11-267145 PATENT LITERATURE 2 Japanese Unexamined Patent Disclosure Publication Number 2004-261442 PATENT LITERATURE 3 Japanese Unexamined Patent Disclosure Publication Number 2011-72612 PRESENTATION OF THE INVENTIONAL PROBLEM

[0003] An absorbent aid may be provided with an adhesive portion on its outer surface for application to the skin-contacting side of an absorbent item. The adhesive portion is generally covered with a release liner before the absorbent aid is used. The absorbent aid, thus designed, is intended to be properly positioned at the desired location on the absorbent item when in use, thereby allowing urine or similar fluids excreted by the wearer to be absorbed by the absorbent aid, thus increasing its absorption capacity and leakage prevention effect.

[0004] The present invention was made in view of the above circumstances, and an object of the present invention is to provide an absorbent auxiliary article which is used by attaching it to a skin-facing side of an absorbent article and which can be easily attached to a desired position of the absorbent article when it is used. SOLUTION TO THE PROBLEM

[0005] The absorbent auxiliary article of the present invention, which solves the above problems, is an absorbent auxiliary article used by being attached to a skin-facing side of an absorbent article and having a longitudinal and a width direction, comprising: a main body comprising an absorber and a fluid-permeable cover layer covering a skin-facing side and an outer-facing side of the absorber; an adhesive part provided on an outer-facing side of the main body; and a peel-off layer provided on an outer-facing side of the adhesive part to cover the adhesive part; wherein the peel-off layer extends in the longitudinal direction and extends outwards in the longitudinal direction beyond at least one end edge in the longitudinal direction of the main body.

[0006] In the absorbent auxiliary article of the present invention, the release liner covering the adhesive portion is designed to extend outwards in the longitudinal direction beyond at least one end edge along the longitudinal direction of the main body, as described above. Therefore, after placing the absorbent auxiliary article on a skin-facing side to determine an approximate application position, the release liner is peeled off by pinching or hooking a longitudinal end of the liner in this state with a finger. This makes it easy to properly attach the absorbent auxiliary article in a desired position without significantly displacing its position.

[0007] Preferably, the peelable layer extends longitudinally beyond both end edges of the main body. This allows the peelable layer to be easily removed from either side along the longitudinal direction of the absorbent auxiliary article, thus facilitating its application.

[0008] Preferably, the covering layer comprises a first covering layer provided on the skin-facing side of the absorber and a second covering layer provided on the outer side of the absorber. Both end portions of the second covering layer are folded back along lateral edges in the width direction of the absorber and connected to a skin-facing side of the first covering layer. By forming the covering layer in this way, a section in which the covering layer extends outwards in the width direction from the absorber is not formed at both ends in the width direction of the absorbent aid, thereby improving the absorption capacity of urine or the like from the lateral sides in the width direction of the absorbent aid.If urine or similar substance is excreted from a carrier onto the first cover layer and diffuses across the first cover layer in the lateral direction, the second cover layer prevents the urine or similar substance from diffusing further outwards in the lateral direction, and a larger quantity of urine or similar substance is easily absorbed by the absorbent auxiliary article.

[0009] In the case of forming the cover layer as described above, it is advantageous that connecting sections of the second cover layer with the first cover layer are formed within a 15 mm radius of both end edges in the width direction of the second cover layer along its entire length, and that the two end edges in the width direction of the second layer are not connected to the first cover layer. In this case, a gap forms between the first cover layer and the end edges in the width direction of the second cover layer, which makes it more difficult for urine or similar substances that have diffused widthwise onto the first cover layer to flow over the second cover layer. Therefore, urine or similar substances are more easily absorbed by the absorbent auxiliary article.

[0010] Preferably, the covering layer extends longitudinally beyond both end edges of the absorber to the outside, thus forming edge sections at both end parts along the longitudinal direction of the main body where the absorber is not present. The adhesive portion is positioned at a location that overlaps the absorber, rather than in a region of the outer half formed by uniformly bisecting the edge section longitudinally. Providing the adhesive portion in this way makes it easy to pinch or hook the longitudinal end of the peel-off layer with a finger, thus facilitating its removal.

[0011] Preferably, the adhesive portion is configured to overlap the main body with a center line in the width direction and to extend longitudinally. Because the adhesive portion is configured in this way, the portion located at a central point in the width direction of the main body acts as an impermeable layer when urine or similar substances excreted by a carrier are absorbed by the absorbent auxiliary article. This makes it less likely that urine or similar substances will rapidly penetrate the absorbent auxiliary article in the thickness direction and will readily diffuse both laterally and longitudinally within the absorbent auxiliary article. Therefore, it is likely that more portions of the absorbent auxiliary article will contribute to the absorption of urine or similar substances.

[0012] The peeling layer is preferably narrower in the width direction than the main body. This allows the main body to be held with one hand and the peeling layer to be clamped with the other hand when peeling the peeling layer off, thus facilitating the peeling process.

[0013] The peel-off layer can be configured to include a first peel-off layer on one side in the longitudinal direction and a second peel-off layer on the other side in the longitudinal direction. The first peel-off layer extends longitudinally beyond one end edge in the longitudinal direction of the main body, and the second peel-off layer extends longitudinally beyond the other end edge in the longitudinal direction of the main body. Providing the first and second peel-off layers in this way makes it even easier to attach the absorbent auxiliary article to a desired position on the absorbent article.This means that after the absorbent aid has been placed on one side of the absorbent article facing the skin to determine an approximate application position, the first backing layer is peeled off while the position of the other side of the absorbent aid is fixed longitudinally, one side of the absorber longitudinally is applied to the skin-facing side of the absorbent article, the second backing layer is further peeled off, and the other side of the absorbent aid longitudinally is applied to the skin-facing side of the absorbent article, thus making it easy to properly apply the absorbent aid in the desired position.

[0014] The peelable layer can be provided with a separable line that divides it longitudinally into two parts. In this case, by separating the peelable layer along the separable line, the first peelable layer and the second peelable layer are formed on one side and the other side, respectively, longitudinally. Even when the peelable layer is formed in this way, it is therefore easy to properly attach the absorbent auxiliary article in the desired position. ADVANTAGEOUS EFFECTS OF THE INVENTION

[0015] In the absorbent auxiliary article of the present invention, an adhesive portion is provided on the outer surface, and a release liner covering the adhesive portion is provided such that it extends outwards in the longitudinal direction beyond at least one end edge in the longitudinal direction of the main body. Therefore, after placing the absorbent auxiliary article on a skin-facing side to determine an approximate application position, the release liner is removed by pinching or hooking a longitudinal end of the release liner with a finger in this state. This makes it easy to properly attach the absorbent auxiliary article in a desired position without significantly displacing its position.

DESCRIPTION OF PREFERRED EXECUTION FORMS

[0016] An absorbent auxiliary article of the present invention is used by attaching it to an absorbent article, in particular by attaching it to a disposable diaper, a urine pad, or the like. The absorbent auxiliary article of the present invention is used by attaching it to a skin-facing side of an absorbent article and serves to prevent the lateral leakage of urine or similar substances by absorbing urine or similar substances that are temporarily excreted in large quantities by the wearer, or to increase the absorption capacity of the absorbent article.

[0017] The absorbent auxiliary article has a longitudinal direction and a lateral direction. The absorbent auxiliary article is generally used such that its longitudinal direction essentially coincides with the front-to-back direction of the absorbent article and the front-to-back direction of the step of a support. The lateral direction of the absorbent auxiliary article is a direction perpendicular to the longitudinal direction in the same plane as the absorbent auxiliary article. Additionally, a direction perpendicular to a plane formed by the longitudinal and lateral directions is defined as the thickness direction. The absorbent auxiliary article has a skin-facing side and a side facing the outside with respect to the thickness direction.The skin-facing side is the side that faces the wearer's skin when the absorbent aid is used, and the outside-facing side is the side that faces away from the wearer when the absorbent aid is used.

[0018] The absorbent auxiliary article has a main body comprising an absorber and a fluid-permeable cover layer that covers one skin-facing side and one outer-facing side of the absorber. The shape of the main body is not particularly restricted. Examples of main body shapes include a substantially rectangular shape, an oval shape, an hourglass shape, a Battledore shape, and others. To facilitate the manufacture of the absorbent auxiliary article, the main body is preferably substantially rectangular.The main body is preferably longer in the longitudinal direction than in the transverse direction, and for example the length in the longitudinal direction of the main body is preferably 2.0 times or more, more preferably 2.5 times or more, even more preferably 3.0 times or more, and preferably 5.0 times or less, more preferably 4.5 times or less, even more preferably 4.0 times or less of the length in the transverse direction of the main body.

[0019] The absorber is not particularly limited in its composition, as long as it contains an absorbent material capable of absorbing excrement such as urine. The absorber can consist of a molded product made of an absorbent material formed into a specific shape as its absorbent core, or the absorbent core can be encased in a cover layer such as paper (e.g., toilet paper and thin paper) and a fluid-permeable nonwoven fabric. Examples of the absorbent material include a hydrophilic fiber such as a cellulose fiber and an absorbent polymer such as an absorbent polyacrylic polymer, an absorbent polyasparagine polymer, an absorbent cellulose polymer, and an absorbent starch-acrylonitrile polymer. The absorbent material can also include a thermally melted fiber such as a polyolefin fiber (e.g., polyethylene and polypropylene), a polyester fiber (e.g., PET), and a polyamide fiber.These thermo-melt fibers can be hydrophilized with a surfactant or similar substance to increase their affinity for urine or similar substances.

[0020] It is preferred that the absorbent material essentially comprises hydrophilic fibers to increase the absorption rate of urine or similar substances. Therefore, the absorber preferably includes an absorbent core formed from an aggregate of hydrophilic fibers (especially cellulose fibers). To further enhance absorption, the absorbent material also preferably contains an absorbent polymer. It is therefore more preferred that the absorbent core be formed from an aggregate of hydrophilic fibers containing an absorbent polymer. In this case, for example, an aggregate of hydrophilic fibers mixed with or dispersed in an absorbent polymer is preferably used as the absorbent core.

[0021] The mass per unit area of ​​the absorber is preferably 100 g / m², for example. 2 or more, preferably 120 g / m² 2 or more, preferably 150 g / m² 2 or more, which can increase the absorption capacity of the absorbent auxiliary article. To prevent the absorbent auxiliary article from being excessively bulky, the mass per unit area of ​​the absorber is preferably 500 g / m². 2 or less, preferably 400 g / m² 2 or less, and even more preferably 300 g / m² 2 or less.

[0022] The covering layer is permeable to liquids and is designed to cover both the skin-facing and the outer-facing side of the absorber. This allows, when the absorbent auxiliary is attached to and used on the skin-facing side of an absorbent article, urine or similar substances excreted by a wearer to be absorbed by the skin-facing side of the absorbent auxiliary, and urine or similar substances that have overflowed the skin-facing side of the absorbent auxiliary can also be absorbed by the outer-facing side of the absorbent auxiliary. Preferably, the covering layer is designed to cover the entire skin-facing and outer-facing side of the absorber.

[0023] A liquid-permeable cover layer can be, for example, a nonwoven fabric made of hydrophilic fibers such as cellulose, rayon, and cotton; a nonwoven fabric made of hydrophobic fibers such as polyolefin (e.g., polypropylene and polyethylene), polyester (e.g., PET), and polyamide (e.g., nylon), in which the hydrophobic fibers on the surface are hydrophilized with a surfactant; or similar materials. The nonwoven fabric can be a spunbond nonwoven, a dot-weave nonwoven, an air-permeable nonwoven, a meltblown nonwoven, an airlaid nonwoven, a spunlace nonwoven, an SMS nonwoven, or similar. A woven fabric, a knitted fabric, or a plastic layer with holes can also be used as a liquid-permeable cover layer.

[0024] The cover layer can consist of a single layer or multiple layers. The main body can be designed, for example, as follows: The cover layer consists of a single layer; a central portion in the width direction of the layer is placed on the outer side of the absorber; both end portions in the width direction of the layer are folded back along lateral edges in the width direction of the absorber onto the skin-facing side of the absorber, so that the two end portions are positioned on the skin-facing side of the absorber; and the two end portions folded back onto the skin-facing side are joined together.The main body can also be formed as follows: The cover layer consists of a single layer; a central portion in the width direction of the layer is placed on the skin-facing side of the absorber; both end portions in the width direction of the layer are folded back along lateral edges in the width direction of the absorber onto the outer side of the absorber, so that the two end portions are positioned on the outer side of the absorber; and the two end portions folded back onto the outer side are joined together. Alternatively, the main body can be formed as follows: The cover layer consists of a single layer; the layer is folded so that it overlaps, the absorber is placed between them, and the circumferential edges of the folded layer are joined together.

[0025] If the cover layer consists of multiple layers, it can comprise a first cover layer on the skin-facing side of the absorber and a second cover layer on the outer side of the absorber. Preferably, both the first and second cover layers are fluid-permeable. In this case, the main body can be configured as follows: The absorber is positioned between the first and second cover layers, and the circumferential edges of the first and second cover layers are connected.Furthermore, the main body can be configured as follows: The absorber is positioned between the first and second cover layers, and both end sections in the width direction of the first cover layer are folded back along the lateral edges in the width direction of the absorber onto the side of the absorber facing the outside and connected to the second cover layer. Alternatively, the main body can also be configured as follows: The absorber is positioned between the first and second cover layers, and the two end sections in the width direction of the second cover layer are folded back along the lateral edges in the width direction of the absorber onto the side of the absorber facing the skin and connected to the first cover layer.

[0026] Preferably, the cover layer is folded back along the side edges in the width direction of the absorber onto the side facing the skin or the side facing the outside. As a result, at both ends in the width direction of the absorbent aid, a section where the cover layer extends outwards from the absorber is not formed, thus improving the absorption capacity of urine or similar substances from the side in the width direction of the absorbent aid. Furthermore, when using the absorbent aid, it is easy to attach the absorbent aid to the skin-facing side of the absorbent, and there is no unpleasant sensation caused by the edge of the cover layer extending outwards from the absorber coming into contact with the wearer's skin.

[0027] On the other hand, it is advantageous that edge sections are formed at both end parts in the longitudinal direction of the main body, in which the cover layers are connected to each other without absorbers. That is, it is preferable for the cover layer to extend outwards in the longitudinal direction beyond both end edges in the longitudinal direction of the absorber, with the edge sections, in which the absorber is not present, being formed at both end parts in the longitudinal direction of the main body. This facilitates handling the absorbent auxiliary article when attaching or removing it from or from a skin-facing side of an absorbent article by grasping the edge sections formed at both end parts in the longitudinal direction of the absorbent auxiliary article.The length of the edge section formed on the two end parts in the longitudinal direction of the main body is preferably 10 mm or more, more preferably 15 mm or more, and preferably 40 mm or less, more preferably 30 mm or less.

[0028] An adhesive portion is located on one of the outer surfaces of the main body. This adhesive portion allows the absorbent auxiliary article to be used by attaching it to the absorbent article. Specifically, the adhesive portion is provided on one of the outer surfaces of the cover layer, which is located on the outer surface of the absorber.

[0029] On the outer side of the adhesive part is a release liner that covers the adhesive. The release liner is designed to be peeled off the adhesive part, and when using the absorbent aid, peeling off the liner exposes the adhesive part, allowing the absorbent aid to be applied to the skin-facing side of the absorbent. The release liner is designed to cover the entire adhesive part.

[0030] The adhesive component can be formed using a pressure-sensitive adhesive. Examples of pressure-sensitive adhesives include rubber-based, acrylic-based, silicone-based, and similar materials. Rubber-based pressure-sensitive adhesives include natural rubber, polyisoprene, styrene-butadiene copolymer (SBR), styrene-isoprene-styrene block copolymer (SIS), styrene-butadiene-styrene block copolymer (SBS), styrene-ethylene-butadiene-styrene block copolymer (SEBS), styrene-ethylene-propylene-styrene block copolymer (SEPS), and others. A single type of pressure-sensitive adhesive can be used, or two or more types can be used in combination.

[0031] The pressure-sensitive adhesive may contain a tackifier, an antioxidant, a plasticizer, a viscosity modifier, or similar substances. Conventionally known tackifiers may be used, such as dicyclopentadiene resin, C5 or C9 hydrocarbon resin, alicyclic hydrocarbon resin, rosin resin, terpene resin, and the like.

[0032] The release layer can consist of, for example, a plastic layer, or it can be a laminate with a plastic layer (e.g., a laminate in which paper, nonwoven fabric, woven fabric, knitted fabric, or similar material is laminated onto a plastic layer). In the latter case, the release layer is configured so that the plastic layer serves as the contact surface with the adhesive part. A base material that undergoes a peeling process can also be used as the release layer. Examples of peeling processes include applying a silicone resin to a base material to form a silicone resin layer (silicone processing). To prevent the silicone resin from penetrating the base material, a sealing layer can be provided between the silicone resin and the base material. The sealing layer consists, for example, of polyethylene or polyvinyl alcohol.If the base material is subjected to the peeling process, paper is preferably used as the base material for reasons of ease of production and cost.

[0033] The peel-off layer is designed to extend longitudinally and outwards beyond at least one end edge of the main body. Because the peel-off layer is designed in this way, the absorbent auxiliary can be easily attached to a desired position on the absorbent. Specifically, after placing the absorbent auxiliary on a skin-facing side of the absorbent to determine an approximate placement position, the peel-off layer is removed by pinching or hooking a longitudinal end of the peel-off layer with a finger. This allows the absorbent auxiliary to be conveniently attached to a desired position without significantly altering the position of the absorbent auxiliary.

[0034] Preferably, the peelable layer extends longitudinally beyond the two end edges of one side and the other side of the main body. This allows the peelable layer to be easily removed from both sides of the absorbent auxiliary article, thus facilitating its application.

[0035] The peel-off layer preferably extends 0.5 mm or more, more preferably 1.0 mm or more, outwards beyond the end edge in the longitudinal direction of the main body. Providing the peel-off layer in this manner allows the longitudinal end of the layer to be easily pinched or hooked with a finger, thus facilitating peeling off the layer. To prevent the peel-off layer from being unintentionally peeled off before the absorbent auxiliary article is used, the peel-off layer preferably extends 5.0 mm or less, more preferably 4.0 mm or less, and even more preferably 3.0 mm or less, outwards from the end edge in the longitudinal direction of the main body.

[0036] The adhesive part is preferably designed to extend continuously or intermittently in the longitudinal direction. By providing the adhesive part in this way, the peel-off layer is stably attached to the main body. In the case where the adhesive part is designed to extend intermittently in the longitudinal direction, the length of the intermittent section is preferably 15 mm or less, more preferably 10 mm or less, and even more preferably 5 mm or less.

[0037] Preferably, the adhesive part is provided at a location that overlaps the absorber. Provided that the absorber is divided longitudinally into three equal parts, i.e., a first section, a second section, and a third section from one side in the longitudinal direction, the adhesive part is preferably provided at least at one location that overlaps the first section and the third section of the absorber. The adhesive part may or may not be provided at a location that overlaps with the second section of the absorber. For the purpose of ensuring stable attachment of the absorbent auxiliary article to a skin-facing side of the absorbent article, the adhesive part is preferably also provided at a location that overlaps with the second section.

[0038] The adhesive portion is preferably located within 20 mm, and more preferably within 15 mm, inward along the longitudinal direction of both end edges of the absorber. By providing the adhesive portion in this manner, the longitudinal ends of the release layer do not protrude excessively loosely beyond the main body, and the release layer is stably attached to the main body. Furthermore, the absorbent auxiliary article can be stably attached to a skin-facing side of an absorbent article. Of course, the adhesive portion can be located in an inner region along the longitudinal direction, and it is, for example, preferable for the adhesive portion to be continuous or intermittent, extending from a region within 20 mm inward along the longitudinal direction of both end edges of the absorber to the second section of the absorber.

[0039] In cases where the edge sections, lacking the absorber, are provided at both ends along the longitudinal direction of the main body, it is preferable that the adhesive portion not be located in a region of the outer half formed by uniformly bisecting the edge section longitudinally (i.e., a region comprising half the edge section on one side of the longitudinal end). Providing the adhesive portion in this manner makes it easy to pinch or hook the longitudinal end of the peel-off layer with a finger, thus facilitating its removal.

[0040] The length of the adhesive portion in the width direction is preferably 60% or less, more preferably 50% or less, than the length of the main body in the width direction. Because the adhesive portion is provided in this way, when attaching the absorbent auxiliary article to a skin-facing side of an absorbent article, the application of the absorbent auxiliary article can be easily carried out by holding a different part of the main body than the adhesive portion. To ensure the adhesive strength of the absorbent auxiliary article on a skin-facing side of an absorbent article, the length of the adhesive portion in the width direction is preferably 10% or more, more preferably 20% or more, of the length of the main body in the width direction.

[0041] Preferably, the adhesive portion is configured to overlap the main body with a center line in the width direction and to extend longitudinally. Because the adhesive portion is configured in this way, the portion located at a central point in the width direction of the main body acts as an impermeable layer when urine or similar substances excreted by a carrier are absorbed by the absorbent auxiliary article. This makes it less likely that urine or similar substances will rapidly penetrate the absorbent auxiliary article in the thickness direction and will readily diffuse both laterally and longitudinally within the absorbent auxiliary article. Therefore, it is likely that more portions of the absorbent auxiliary article will contribute to the absorption of urine or similar substances.

[0042] The peelable layer preferably does not extend beyond the end edges of the main body in the width direction and is preferably narrower in the width direction than the main body. Therefore, when peeling the peelable layer from the main body, the main body can be held with one hand and the peelable layer clamped with the other, thus facilitating the peeling process. The length of the peelable layer in the width direction is preferably 70% or less, more preferably 60% or less, than the length of the main body in the width direction.

[0043] Only one peel-off layer, or two or more peel-off layers, can be provided. For example, two or more peel-off layers can be arranged side by side in the width direction, and these layers can be spaced apart, abutting each other, or partially overlapping. In this case, only one adhesive part extending in the longitudinal direction can be provided, or two or more adhesive parts can be provided side by side in the width direction.

[0044] Two peeling layers can also be provided side by side in the longitudinal direction. In this case, a first peeling layer is provided on one side in the longitudinal direction, and a second peeling layer on the other side in the longitudinal direction. The first peeling layer can be designed to extend outwards in the longitudinal direction beyond one end edge in the longitudinal direction of the main body, and the second peeling layer can be designed to extend outwards in the longitudinal direction beyond the other end edge in the longitudinal direction of the main body. The first and second peeling layers can be arranged separated from each other in the longitudinal direction, adjacent to one another, or partially overlapping.By providing the first and second release layers in this manner, it becomes even easier to properly attach the absorbent aid to the desired position on the absorbent item. That is, after placing the absorbent aid on one side of the absorbent item facing the skin to determine an approximate application position, the first release layer is peeled off while the position of the other side of the absorbent aid is fixed longitudinally. One side of the absorber is then applied longitudinally to the skin-facing side of the absorbent item. The second release layer is then peeled off, and the other side of the absorbent aid is applied longitudinally to the skin-facing side of the absorbent item, thus allowing the absorbent aid to be properly applied to the desired position.

[0045] The peelable layer can be provided with a separable line, e.g., a perforation, and designed so that it can be separated into two parts by cutting along the separable line in the longitudinal direction. In this case, by cutting the peelable layer along the separable line, the first peelable layer and the second peelable layer are formed on one side and the other side in the longitudinal direction, respectively. The separable line can be designed to run straight in the width direction, or it can be designed to run diagonally. The separable line can be straight or curved (e.g., in a meander).In this case, it is advantageous that the adhesive part is not located at a point that overlaps with the separable line, making it easy to separate the peelable layer at the separable line when the peelable layer is pulled lengthwise from one side or the other.

[0046] An example of the configuration of the absorbing auxiliary article of the present invention is explained below with reference to the drawings. Fig. 1 to Fig. Figure 3 shows an example of the absorbent auxiliary article of the present invention, Fig. Figure 1 shows a top view of the absorbing auxiliary article as seen from one side of the same facing the skin. Fig. 2 shows a top view of the in Fig. 1 of the absorbing auxiliary article shown, viewed from one of its outer sides, and Fig. Figure 3 shows a cross-sectional view along line III-III of the in Fig. 1 and Fig. The absorbent auxiliary article shown in Figure 2. In the drawings, an arrow x represents a width direction, an arrow y a length direction, and an arrow z a thickness direction. The present invention is not limited to the embodiments shown in the drawings.

[0047] An absorbent auxiliary article 1 comprises a main body 2 in which an absorber 3 is covered with a liquid-permeable cover layer 4, an adhesive part 7 provided on an outer-facing side of the main body 2, and a peelable layer 8 provided on an outer-facing side of the adhesive part 7 to cover the adhesive part 7. The peelable layer 8 extends in the longitudinal direction y and extends outwards in the longitudinal direction y beyond the two end edges in the longitudinal direction y of the main body 2.In the absorbent auxiliary article 1 shown in the drawing, the adhesive part 7 is designed to overlap the absorber 3 and extend in the longitudinal direction y along a central portion in the width direction x of the main body 2, and the release layer 8 is designed to cover the adhesive part 7 and extend in the longitudinal direction y along the central portion in the width direction x of the main body 2. By providing the release layer 8 in this way, the absorbent auxiliary article 1 can be easily attached to a desired position on an absorbent article. This is illustrated by the drawing. Fig. 4 and Fig. 5 explained.

[0048] The Fig. 4 and Fig. Figure 5 shows an example of attaching the absorbent auxiliary article to an absorbent article (a disposable diaper with adhesive tape). Fig. Figure 4 shows a top view of the absorbent auxiliary article 1 before the peel-off layer 8 is removed, in a state in which the absorbent auxiliary article 1 is placed on a skin-facing side of a disposable diaper with adhesive tape 11, and Fig. Figure 5 shows a cross-sectional view (i.e., the VV cross-section in Fig. 4) of the absorbent auxiliary article 1 when the peel-off layer 8, which is attached to the skin-facing side of the absorbent article 11 with the adhesive part 7, has been removed.

[0049] The disposable diaper 11 consists of an upper layer 12, a lower layer 13, and an absorbent layer 14 sandwiched between them. The upper layer 12 is located on the side facing the carrier when the absorbent item is worn and is preferably permeable to liquids. A hydrophilic nonwoven fabric, a perforated plastic layer, or a similar material can be used as the upper layer 12. The lower layer 13 is located on the side facing away from the carrier, i.e., on the outside when the absorbent item is worn, and is preferably impermeable to liquids. A hydrophobic nonwoven fabric, a plastic layer, or a laminate consisting of a nonwoven fabric and a plastic layer can be used as the lower layer 13.The absorber 14 is not particularly limited as long as it contains an absorbent material capable of absorbing excrement such as urine, and reference is made to the description of the absorber of the absorbent auxiliary article.

[0050] On both sides of the upper layer 12, a pair of lateral layers 15 are provided in the width direction, extending in the front-back direction. The lateral layer 15 is connected to the upper layer 12, and at its inner end is a rising elastic element 16. Due to the contraction force of the rising elastic element 16, the inner end of the lateral layer 15 is oriented towards the skin of the wearer, thus forming a rising flap.

[0051] The disposable diaper 11 is provided with fastening elements 17 on both sides in the width direction of a rear section, and a fastening receptacle 18 is provided on one of the outer sides of a front section. The fastening element 17 is configured to be attached (e.g., with hook-and-loop fasteners or adhesive) to a base layer. The disposable diaper 11 is put on in the crotch of the wearer, and the fastening element 17 engages with the fastening receptacle 18, thereby shaping the absorbent article 11 into a trouser-like form for wearing.

[0052] At both end sections of the disposable diaper 11, elastic leg sections 19 extending in the front-to-back direction are preferably provided. The elastic element 19 at the legs forms a gather around the wearer's legs, improving the fit of the disposable diaper 11. The disposable diaper 11 is also preferably provided with an elastic waist element 20 extending in the front-to-back direction at one end section. The elastic waist element 20 forms a waist belt around the wearer's waist to prevent leakage of urine or similar substances from the abdomen or back.

[0053] As in Fig. As shown in Figure 4, when attaching the absorbent aid 1 to a skin-facing side of the disposable diaper 11, the absorbent aid 1 is first placed on the skin-facing side of the disposable diaper 11 to determine an approximate attachment position. In the Fig. In the disposable diaper 11 shown in Figure 4, the absorbent aid 1 is placed between the rising tabs formed by the left and right side layers 15. The peel-off layer 8 is then peeled back by pinching or hooking one end of the peel-off layer 8 with a finger in this state, allowing the absorbent aid 1 to be positioned appropriately without its position changing significantly. Since the end of the peel-off layer 8 protrudes from the main body 2 of the absorbent aid 1 when the absorbent aid 1 is placed on the skin-facing side of the disposable diaper 11, pinching the end of the peel-off layer 8 is facilitated. Furthermore, it is easy to position the absorbent aid 1 in the center of the disposable diaper 11 in the width direction, with the peel-off layer 8 serving as an indicator.

[0054] As in the Fig. 1 and Fig. As shown in Figure 2, it is advantageous that the covering layer 4 encasing the absorber 3 extends outwards in the longitudinal direction y beyond both end edges in the longitudinal direction y of the absorber 3, thereby forming edge sections 6 at both end parts in the longitudinal direction y of the main body 2 in which the absorber 3 is not present. By providing the edge section 6 in this way, the absorbent auxiliary article 1 can be easily handled when attaching to or removing it from the skin-facing side of the disposable diaper 11 by grasping the edge section 6.

[0055] Preferably, the adhesive part 7 is provided at a point that overlaps with the absorber 3, and not in a region of the outer half formed by uniformly bisecting the edge section 6 in the longitudinal direction y. This way of providing the adhesive part 7 allows the end of the peel-off layer 8 to be easily pinched or hooked with a finger in the longitudinal direction y, thus facilitating the peeling off of the peel-off layer 8. Fig. 2 the adhesive part 7 is not provided at all in the edge section 6, however the adhesive part 7 may be provided in an area of ​​the inner half which is formed by uniformly halving the edge section 6 in the longitudinal direction y.

[0056] The peeling layer 8 is preferably narrower in the width direction x than the main body 2. This allows the main body 2 to be held with one hand and the peeling layer 8 to be clamped with the other hand when peeling the peeling layer 8 from the main body 2, thus facilitating the peeling of the peeling layer 8.

[0057] As in Fig. As shown in Figure 3, the cover layer 4 preferably comprises a first cover layer 4A, which is provided on a skin-facing side of the absorber 3, and a second cover layer 4B, which is provided on an outer-facing side of the absorber 3. Both end parts are folded back in the width x direction of the second cover layer 4B along lateral edges in the width x direction of the absorber 3 and connected to the skin-facing side of the first cover layer 4A. By forming the cover layer 4 in this way, a section in which the cover layer 4 extends outwards in the width x direction from the absorber 3 is not formed at both ends in the width x direction of the absorbent auxiliary article 1, thereby improving the absorption capacity of urine or the like from the sides in the width x direction of the absorbent auxiliary article 1.If urine or similar substance is excreted from a carrier onto the first cover layer 4A and diffuses across the first cover layer 4A in the lateral direction x, the second cover layer 4B prevents the urine or similar substance from diffusing further outwards in the lateral direction x, and the urine or similar substance is readily absorbed by the absorbent auxiliary article 1 in a suitable manner.

[0058] Preferably, the connecting sections 5 of the second cover layer 4B with the first cover layer 4A are formed in an area within 15 mm of both end edges in the width direction x of the second cover layer 4B over the entire length direction y, and both end edges in the width direction x of the second layer 4B are not connected to the first cover layer 4A. That is, it is advantageous that the two end edges in the width direction x of the second cover layer 4B are not attached to the first cover layer 4A with an adhesive or the like and are free ends. In this case, a gap forms between the first cover layer 4A and the end edges in the width direction x of the second cover layer 4B, which makes it difficult for urine or similar substances that have diffused in the width direction x onto the first cover layer 4A to flow over the second cover layer 4B.Therefore, urine or similar substances are more easily absorbed by the absorbent auxiliary article 1. The connecting section 5 is preferably formed in a region within 12 mm, and even more preferably in a region within 10 mm, of both end edges in the width direction x of the second cover layer 4. Furthermore, it is advantageous that no elastic element is provided on one edge side in the width direction x (i.e., an inside side in the width direction x) of the connecting section 5 in the second cover layer 4B.

[0059] The end edge on one side and the end edge on the other side in the width direction x of the second cover layer 4B, which is folded back onto the skin-facing side of the absorber 3, are preferably 20 mm or more, more preferably 25 mm or more, and even more preferably 30 mm or more apart in the width direction x. As a result, an area of ​​the section where the first cover layer 4A does not overlap with the second cover layer 4B on the skin-facing side of the absorber 3 is protected, and urine or similar substances excreted onto the first cover layer 4A are immediately absorbed by the absorbent auxiliary article 1.

[0060] The adhesive part 7 is preferably designed to overlap a center line in the lateral direction x of the absorbent auxiliary article 1 and to extend in the longitudinal direction y. When the adhesive part 7 is designed in this way, urine or similar substances excreted by a carrier are first absorbed by the absorbent auxiliary article 1 and then diffuse in the lateral direction x or the longitudinal direction y due to the adhesive part 7, which is provided in the central part in the lateral direction x within the absorbent auxiliary article 1, as shown in Fig.Figure 5 shows how more parts of the absorbent aid 1 contribute to the absorption of urine or similar substances. As urine or similar substances continue to be absorbed by the absorbent aid 1 in this state, the urine or similar substances move through a non-existent portion of the adhesive part 7 to the disposable diaper 11 located beneath the absorbent aid 1, and the urine or similar substances are absorbed by the absorber 13 of the disposable diaper 11. By using the absorbent aid 1 together with the disposable diaper 11, a large quantity of urine or similar substances can be absorbed at once in this way.
