[0008] The following describes an absorbent article according to an embodiment of the present invention with reference to the drawings. Note that the configurations of the following embodiments are illustrative, and the present invention is not limited to these embodiments.

[0009] <Embodiment> In this embodiment, for a replaceable absorbent pad (an example of an "absorbent article" as referred to in this application), the direction connecting the front panel positioned opposite the wearer's abdomen and the back panel positioned opposite the wearer's back is defined as the longitudinal direction. Between these front panel (one side in the longitudinal direction) and back panel (the other side in the longitudinal direction) (in the center in the longitudinal direction), the inseam section, positioned between the wearer's legs (opposite the crotch), is connected. Furthermore, when the absorbent pad is attached to the wearer (hereinafter abbreviated as "attached state"), the side facing the wearer's skin (the inside when attached) is defined as the skin side, and the side opposite the skin side (the outside when attached) is defined as the non-skin side. In addition, the direction connecting the skin side and the non-skin side is defined as the thickness direction, and the direction perpendicular to both the longitudinal direction and the thickness direction is defined as the width direction. Moreover, viewing from the thickness direction is defined as a plan view.

[0010] Figure 1 is an external perspective view of the absorbent pad according to the embodiment. Figure 2 is an exploded perspective view of the absorbent pad according to the embodiment. The absorbent pad 1 has a crotch region 1B that covers the wearer's genitals when worn, a front body region 1F located in front of the crotch region 1B and corresponding to the wearer's front body, and a back body region 1R located behind the crotch region 1B and corresponding to the wearer's back body. The absorbent pad 1 according to this embodiment has a substantially rectangular shape.

[0011] The absorbent pad 1 incorporates an absorbent material 4 in the front body region 1F, the back body region 1R, and the crotch region 1B, primarily in the crotch region 1B. A back sheet 3 is provided on the non-skin side of the absorbent material 4, having a wider vertical and horizontal width than the absorbent material 4. The back sheet 3 is a film-like sheet formed from a thermoplastic resin such as polyethylene film. The back sheet 3 is a non-permeable sheet that prevents wastewater that has flowed into the absorbent material 4 from leaking to the non-skin side. The back sheet 3 may also be made of a material that has breathability to reduce stuffiness when worn. The back sheet 3 is an example of a non-skin side sheet according to this disclosure.

[0012] The absorbent pad 1 does not have a laminated cover sheet. Therefore, the entire non-skin side of the back sheet 3 is exposed to the non-skin surface of the absorbent pad 1. Since the absorbent pad 1 according to this embodiment does not have a cover sheet, costs can be reduced. Because the back sheet 3 is in the form of a film, it has smoothness and a low static friction coefficient of 0.63.

[0013] The absorbent core 4 is provided with a top sheet 6, which is a water-permeable skin-facing sheet, on its skin-facing side. The top sheet 6 is a sheet made of spunbond nonwoven fabric or air-through nonwoven fabric, etc., which contains thermoplastic resin fibers, and is positioned on the skin-facing side of the wearer so as to cover the absorbent surface of the absorbent core 4. The top sheet 6 is partially or entirely permeable to liquids. When the absorbent pad 1 is attached, the discharged liquid released from the wearer enters the absorbent core 4 through the top sheet 6, which can come into contact with the wearer's skin, and is absorbed there. The top sheet 6 may also be hydrophilic.

[0014] On the outer edges of both ends of the absorbent body 4 in the width direction, elastic threads 3L and 3R are arranged in an extended state, parallel to the longitudinal direction. When worn, the areas where the elastic threads 3L and 3R are arranged rise up to conform to the wearer's skin surface due to the biasing force of the elastic threads 3L and 3R, improving the wearing comfort and functioning as a fit gather to suppress lateral leakage of discharged fluid. Multiple elastic threads 3L and 3R may be arranged on each of the outer edges of the absorbent body 4 in the width direction; in this embodiment, two of each are arranged on the outer edges of the absorbent body 4 in the width direction. The elastic threads 3L and 3R are examples of longitudinally extending elastic members in this disclosure, and the fit gather is an example of leg gather in this disclosure.

[0015] Figure 3 is a plan view of the absorbent pad according to this embodiment. 1 has a symmetric configuration in both the longitudinal direction and the width direction. Therefore, the wearer or caregiver can attach the absorbent pad without considering the attachment direction. Regardless of the attachment direction, the backsheet 3, the absorber 4, and the topsheet 6 all extend from the front body region 1F to the back body region 1R. Thus, when the absorbent pad 1 is inserted between the diaper or undergarment and the skin surface to cover the wearer's genital area, both longitudinal ends of the backsheet 3, the absorber 4, and the topsheet 6 are positioned on the ventral and dorsal sides of the wearer. Therefore, the wearer's excretory opening corresponds to the absorber 4.

[0016] The topsheet 6, like the backsheet 3, has a longer longitudinal width and a wider lateral width than the absorber 4. Also, the lateral width of the topsheet 6 is wider than that of the backsheet 3. Therefore, at the widthwise ends of the absorbent pad 1, the film-like backsheet 3 is covered by the topsheet 6 and does not come into direct contact with the wearer's skin surface. Thus, even if the backsheet 3 is exposed on the non-skin side, the wearer is less likely to feel discomfort.

[0017] Further longitudinally outside the end of the absorber 4 at the longitudinal end of the absorbent pad 1, the backsheet 3 and the topsheet 6 are firmly adhered by heat fusion such as heat sealing. Since the sheets are adhered longitudinally outside the longitudinal end of the absorber 4, the position of the absorber 4 is kept constant. Due to this adhesion, the discharged liquid that has flowed into the absorber 4 is less likely to flow out further from the longitudinal ends of the absorbent pad 1. Also, due to this adhesion, peeling of the backsheet 3 and the topsheet 6 is suppressed at the longitudinal ends where relatively more force is likely to be applied. Note that the adhesion of the backsheet 3 and the topsheet 6 at the longitudinal ends of the absorbent pad 1 may be made by a hot melt adhesive applied in a planar shape. Note that further laterally outside the widthwise end of the absorber 4 of the absorbent pad 1, the backsheet 3 and the topsheet 6 are adhered by a hot melt adhesive that is linearly applied in the longitudinal direction and a plurality of which are applied in parallel at a predetermined interval in the width direction. Lateral leakage of the discharged liquid that has flowed into the absorber 4 is suppressed by the hot melt adhesive.

[0018] FIG. 4 is a cross-sectional view when the central portion of the absorbent pad is cut along the width direction. In FIG. 4, in order to clearly show the internal structure of the absorbent pad 1, each structure is greatly emphasized and gaps are provided between the structures. However, in reality, the cross-section of the absorbent pad 1 is thin and each internal structure is in close contact. The absorber 4 has an absorption core 4c and a core wrap sheet 5 that covers the absorption core 4c. The absorption core 4c has a structure in which granular absorbent resin (high molecular water absorbent material) such as SAP (super absorbent polymer), which is a hydrophilic polymer having a cross-linked structure capable of absorbing and holding water, is held in the gaps between short fibers of cellulose-based fibers such as pulp fibers, rayon fibers, or cotton fibers, or short fibers obtained by subjecting synthetic fibers such as polyethylene, polypropylene, or polyethylene terephthalate to a hydrophilization treatment.

[0019] The SAP particles in this embodiment refer to those in which a resin composition containing SAP is formed into granules. The "resin composition containing SAP" mentioned here is a concept that includes both a composition consisting only of SAP and a composition having SAP as the main component and containing other substances to such an extent that it does not adversely affect water absorption. Examples of the "other substances" include additives (such as surface modifiers added for the purpose of hydrophobizing the particle surface) and unreacted monomers remaining during the synthesis of SAP.

[0020] In this embodiment, the absorption core 4c has a two-layer structure of an upper absorption core 4a and a lower absorption core 4b. And an SAP layer 4s made of SAP particles is provided between the upper absorption core 4a and the lower absorption core 4b. While the SAP particles can be gelled and retain moisture, absorption takes a certain amount of time. Therefore, until the SAP particles absorb moisture, the short fibers diffuse inside the absorption core 4c while decelerating the discharged liquid, and absorb the discharged liquid into a wide range of SAP particles to suppress backflow.

[0021] The core wrap sheet 5 has an upper core wrap sheet 5a that is placed between the absorbent core 4c and the top sheet 6, and a lower core wrap sheet 5b that is placed on the non-skin side of the absorbent core 4c, covers the sides of the absorbent core 4c, and also covers the outer width of the upper core wrap sheet 5a. By arranging the upper core wrap sheet 5a and the lower core wrap sheet 5b in this way, the core wrap sheet 5 covers all of the skin side, non-skin side, and sides of the absorbent core 4c. By covering the absorbent core 4c with the core wrap sheet 5, the absorbent core 4c becomes less prone to deformation, and the deterioration of its function is suppressed.

[0022] In the widthwise center of the absorbent pad 1, which corresponds to the midline of the wearer's body, the core wrap sheet 5 separating the skin side from the absorbent core 4c consists only of the upper core wrap sheet 5a, so the discharged fluid passes through the core wrap sheet 5 relatively easily. On the other hand, at the widthwise ends, the core wrap sheet 5 is double-layered, consisting of the upper core wrap sheet 5a and the lower core wrap sheet 5b, so the movement of discharged fluid outward in the widthwise direction is suppressed. Furthermore, backflow caused by compression of the absorbent core 4c at the widthwise outer side of the absorbent body 4, where body weight is relatively likely to be applied, can be suppressed.

[0023] The core wrap sheet 5 can be formed, for example, from a permeable pulp fiber sheet, or more specifically, from tissue paper. The materials of the upper core wrap sheet 5a and the lower core wrap sheet 5b may be the same or different. The upper core wrap sheet 5a needs to quickly move the incoming discharged liquid to the absorbent core 4c, and to minimize discomfort to the wearer via the top sheet 6, it may be made of a material with low rigidity or may be hydrophilic. On the other hand, the lower core wrap sheet 5b may be made of a material with relatively high rigidity to help maintain the shape of the absorbent core 4c and to suppress the movement of discharged liquid towards the back sheet 3.

[0024] In this embodiment, multiple hot-melt adhesives HM are applied intermittently in the longitudinal direction and at regular intervals in the width direction between the top sheet 6 and the skin-facing side of the absorbent 4. The top sheet 6 and the absorbent 4 are temporarily bonded by the hot-melt adhesive HM. Temporary bonding refers to a state of adhesion strong enough to allow the top sheet 6 to be peeled off the absorbent 4 without damaging the absorbent pad 1, such as by tearing it. This temporary bonding state can be achieved by adjusting the placement of the hot-melt adhesive HM, or by adjusting the performance and amount of the adhesive applied.

[0025] On the skin-facing side of the absorbent material 4, the absorbent material 4 and the top sheet 6 are in a temporary bonded state, making it easy for at least a portion of the top sheet 6 to peel off from the absorbent material 4. As a result, the top sheet 6, which contains moisture such as urine, adheres to the wearer's skin. This allows the absorbent pad 1 according to this embodiment to improve its fixation force to the wearer, thereby suppressing displacement within the diaper and improving wearing comfort. Furthermore, because the top sheet 6 has significantly less rigidity compared to other components of the absorbent pad 1, it adheres easily to the skin and is more likely to stick to it.

[0026] On the other hand, hot melt adhesive HM is also applied intermittently in the longitudinal direction and at predetermined intervals in the width direction between the non-skin side of the absorbent material 4 and the back sheet 3. The back sheet 3 and the non-skin side of the absorbent material 4 are bonded together by this hot melt adhesive HM. On the non-skin side of the absorbent material 4, the spacing between the hot melt adhesive HM is denser in the width direction compared to the skin side. Also, the back sheet 3 is in film form and is less likely to peel off from the hot melt adhesive HM compared to the top sheet 6, which is a nonwoven fabric. For this reason, the absorbent material 4 and the back sheet 3 are bonded together. Bonded state means that the absorbent pad 1 cannot be torn or otherwise damaged. The adhesive is strong enough that the bonded areas cannot be separated without further action.

[0027] Furthermore, as shown in Figures 2 and 3, the top sheet 6 and back sheet 3 are longer in the width direction than the absorbent material 4 and extend outward from the widthwise end of the absorbent material 4. Here, the top sheet 6 is longer in the width direction than the back sheet 3 and extends outward from the widthwise end of the back sheet 3. For this reason, the top sheet 6 is the outermost part in the width direction within the absorbent pad 1 and comes into contact with materials such as diapers used in combination. The top sheet 6 becomes wet with urine or other fluids discharged by the wearer and adheres tightly to materials such as diapers. In this embodiment, the diaper 1 can also suppress displacement due to the adhesive force provided by this top sheet 6.

[0028] Furthermore, the frequency of diaper changes is lower than that of the absorbent pad 1, and there are cases where a new absorbent pad 1 is placed inside the diaper while the top sheet of the diaper is still wet. In this case, the portion of the top sheet 6 of the absorbent pad 1 that extends outward in the width direction comes into contact with the top sheet of the diaper and becomes wet. Because the top sheet 6 adheres tightly to the top sheet of the diaper when wet, the absorbent pad 1 can be prevented from shifting position.

[0029] Furthermore, in the absorbent pad 1 according to this embodiment, the skin-facing side of the top sheet 6 does not have a water-impermeable leak-proof sheet that forms three-dimensional gathers, and the top sheet 6 is positioned closest to the wearer across its entire width. Normally, the absorbent pad 1 is placed between a pair of three-dimensional gathers of the diaper used in combination. Because the absorbent pad 1 does not have a leak-proof sheet, the top sheet 6 comes into contact with the three-dimensional gathers of the diaper. In this state, when liquid discharged by the wearer is spread across the entire width of the top sheet 6, moisture is created between the top sheet 6 and the three-dimensional gathers of the diaper, and the surface tension between them causes the top sheet 6 and the three-dimensional gathers of the diaper to adhere tightly, suppressing displacement of the absorbent pad 1. It is also conceivable that discharged liquid may leak from the absorbent pad 1 and enter between the diaper and the back sheet 3. The presence of moisture between the back sheet 3 and the top sheet of the diaper causes the surface tension between them to adhere tightly, suppressing displacement of the absorbent pad 1.

[0030] Figure 5 shows the application of adhesive on the non-skin side of the absorbent pad according to the embodiment. As described above, on the outer side of the longitudinal end of the absorbent body 4, the back sheet 3 and the top sheet 6 are heat-fused together by heat sealing or the like to form a heat-sealed portion HS. Furthermore, hot melt adhesive HM is applied between the back sheet 3 and each structure that comes into contact with the back sheet 3. In the area where the absorbent body 4 extends, the hot melt adhesive HM is applied between the absorbent body 4 and the back sheet 3, and outside the area where the absorbent body 4 extends, it is applied between the back sheet 3 and the top sheet 6, in multiple linear applications in the longitudinal direction and parallel applications in the width direction with predetermined intervals. Also, since the hot melt adhesive HM is applied intermittently, the applied areas appear as dotted lines.

[0031] Because the backsheet 3 is a thin film, when the hot melt adhesive HM cools and solidifies, an uneven surface is formed in the longitudinal direction due to the presence of the hot melt adhesive HM and the resulting adhesion to other structures, as well as the absence of the hot melt adhesive HM and the resulting lack of adhesion. When the finished absorbent pad 1 is viewed from the non-skin side, the surface of the backsheet 3 shows recessed areas where it is adhered to other structures by the hot melt adhesive HM, and raised areas where the hot melt adhesive HM is not applied and the pad is not adhered. Since the hot melt adhesive HM is applied intermittently in the longitudinal direction, this uneven surface is formed in the longitudinal direction. This uneven surface functions as an anti-slip surface extending in the longitudinal direction.

[0032] Although the back sheet 3 itself is smooth, the irregularities formed along its length provide anti-slip properties. It functions as such. Therefore, the absorbent pad 1 is less likely to shift position between itself and the diaper or undergarments while being worn. Thus, the absorbent pad 1 in this disclosure can easily maintain its position without the need for a non-slip cover sheet on the non-skin side or additional structures such as anti-slip tape.

[0033] The anti-slip effect described above is exhibited not only while the absorbent pad 1 is attached, but also before the absorbent pad 1 is attached. The anti-slip effect before the absorbent pad 1 is attached will be described below. Figure 6 shows an example of how the absorbent pad is folded. Figure 6(A) shows the bending of the absorbent pad 1 before use. Before use, such as at the time of factory shipment, distribution, and storage, the absorbent pad 1 is folded in a C-shape in the width direction and further folded into thirds in the length direction. More specifically, the absorbent pad 1 is distributed with the outer side in the width direction of the fold line 7, shown by a dashed line and located near the width direction end of the absorbent body 4, folded toward the skin side, and the outer side in the length direction of the fold line 8, which divides the absorbent pad 1 into approximately three equal parts in the length direction, folded toward the length direction.

[0034] Figure 6(B) shows a folded absorbent pad 1. The absorbent pad 1 is distributed folded in the form shown in Figure 6(B). Before use, the widthwise edges of the absorbent pad 1 are folded inward along the fold line 7, and the longitudinal outer edges are folded inward along the fold line 8. Because it is folded in this way, before use, the back sheet 3 is exposed to the outside of the entire surface of the absorbent pad 1, and the more delicate absorbent material 4 and top sheet 6 are not exposed to the surface, thus suppressing performance degradation before use.

[0035] Although the backsheet 3 exposed to the outside of the absorbent pad 1 before use is smooth, the surface of the backsheet 3 has uneven surfaces 9 formed due to the hot melt adhesive HM that is intermittently applied to the internal structure side and hardened. These uneven surfaces 9 function as an anti-slip surface, allowing the wearer or caregiver to easily grasp and handle the absorbent pad 1 before use. For example, the user can grasp the absorbent pad 1 before use and pull it out in the direction of the removal direction 12 indicated by the arrow.

[0036] Figure 7 shows a package of absorbent pads sealed in an sealing bag. Before use, as shown in Figure 6, for example, multiple absorbent pads 1 are folded and stacked in the thickness direction to form a stack, and this stack is compressed in the thickness direction and sealed in a roughly rectangular sealing bag 10 to form the package 20. Multiple stacks may be stacked and sealed, and Figure 7 shows an example with two stacks. Absorbent pads 1 are changed more frequently than diapers, so the number of pads consumed is also large, but by forming a stack, compressing it, and sealing it in the sealing bag 10, handling during distribution and storage becomes easier. The sealing bag 10 may be made of a thermoplastic resin film, a nonwoven fabric, or paper.

[0037] The surface of the sealing bag 10 may include a description of the absorbent pad and instructions for use. Furthermore, the top and bottom surfaces of the sealing bag 10 may have tabs, and the tab on the top surface may have a handle or a perforated section that can be used as a handle by the user tearing along the perforation. The user can then more easily transport the package 20 by inserting their fingers into the handle of the sealing bag 10 and gripping it.

[0038] The package 20 can have an opening 11 from which the absorbent pad 1 can be removed from the inside. The opening 11 can be formed, for example, by pre-perforating the surface of the sealing bag 10 and allowing the user to open the perforations. It is desirable that the opening 11 be shaped in such a way that the user can remove the absorbent pad 1 relatively easily, and that other absorbent pads 1 do not easily move to the outside of the package 20 and scatter in conjunction with it.

[0039] The back sheet 3 is exposed on the outer surface of the folded absorbent pad 1, and the back sheet 3 is smooth. Therefore, when a user inserts their hand through the opening 11 of the package 20 and takes out any absorbent pad 1, other absorbent pads 1 are taken out in conjunction, making it less likely for them to scatter around. On the other hand, if the back sheet 3 exposed on the surface of the enclosed absorbent pad 1 is smooth, it becomes difficult for the user to grasp the absorbent pad 1, and it becomes difficult to take the absorbent pad 1 out of the package 20.

[0040] The absorbent pad 1 according to this disclosure has its widthwise end folded inward, so in the folded state, the widthwise end is thicker and the widthwise center is thinner. Therefore, with the opening 11 formed, the user can easily insert their fingers into the thin portion between the multiple absorbent pads 1 forming the stack and grasp any absorbent pad 1. The back sheet 3 has multiple anti-slip protrusions 9 spaced apart in the direction of the removal direction 12 indicated by the arrow. These protrusions 9 function as an anti-slip feature when the user grasps the absorbent pad 1 and pulls it out in the removal direction 12, making removal easier. With this configuration, the user can easily grasp the absorbent pad 1, which has a smooth surface on the back sheet 3 exposed on the outer side, and reliably remove it from the package 20.

[0041] Thus, the absorbent pad 1 according to this disclosure is easy to handle during distribution, storage, and use, and can effectively perform its function. Furthermore, since it does not require structures such as cover sheets or anti-slip tapes used in known absorbent pads, it is low-cost and not bulky. Therefore, it can be said that it has characteristics that make it very suitable as an absorbent pad that is replaced frequently.

[0042] Although this embodiment has been described above, the present invention is not limited to the above embodiment. For example, several strands of hot melt adhesive HM may be applied to the non-skin side of the back sheet 3 of the absorbent pad 1 according to this disclosure. The hot melt adhesive HM functions effectively as an anti-slip agent.

[0043] The features included in each embodiment and its modified form disclosed above can be combined in any way. [Explanation of Symbols]
