Summary of the Invention

Problems to be Solved by the Invention

[0004] On the other hand, when the absorbent article absorbs a large amount of excrement, the swelling in the thickness direction increases, so it may be difficult to roll it up from the end. In that case, an absorbent article provided with a closing mechanism that closes in a folded state with the skin side facing inward is desired. The closing mechanism is provided, for example, such that when the absorbent article is folded in half with the skin side facing inward, a bonding agent such as an adhesive or a self-adhesive faces the both ends of the absorbent article. In such an absorbent article provided with a closing mechanism, after use, by closing the skin side surface to which excretory fluid has adhered, it can be hygienically discarded while confining the excretory fluid and its odor.

[0005] However, when the closing mechanism is provided on the skin side surface, it is difficult to recognize the position of the closing mechanism from the outside (non-skin side), and there is a risk that it will be difficult to sufficiently crimp the closing mechanism. In addition, when trying to confirm the position of the closing mechanism by opening the skin side surface, problems occurred in terms of hygiene and odor.

[0006] This embodiment has been made in view of the above-mentioned problems, and its purpose is to provide an absorbent article equipped with a closing mechanism, in which the closing mechanism can be pressed into place without having to open and check the skin side. [Means for solving the problem]

[0007] The main invention for achieving the above objective is: In its unfolded state, it has longitudinal, widthwise, and thicknesswise directions that are mutually orthogonal to each other. An absorbent article having a liquid-absorbing core, The skin-facing side has a bonding means that can be attached to a part of the absorbent article when discarded. It has a marker that is visible from the non-skin side, The absorbent article is characterized in that, when viewed in the thickness direction in an unfolded and extended state, it has a portion where the joining means and the mark overlap. Other features of the present invention will be made clearer by description in this specification and the accompanying drawings. [Effects of the Invention]

[0008] According to the present invention, it is possible to provide an absorbent article equipped with a closing mechanism, in which the closing mechanism can be compressed without opening and checking the skin side. [Brief explanation of the drawing]

Mode for Carrying Out the Invention

[0010] From the description in this specification and the accompanying drawings, at least the following matters become clear. (Aspect 1) An absorbent article having a longitudinal direction, a width direction, and a thickness direction that are orthogonal to each other in the deployed state, and having a liquid-absorbent absorbent core, having joining means on the skin side that can be joined to a part of the absorbent article at the time of disposal, having marks visible from the non-skin side, and having a portion where the joining means and the marks overlap when viewed in the thickness direction in the deployed and extended state.

[0011] According to Aspect 1, when the absorbent article is folded with the skin side facing inward at the time of disposal, by pressing the mark portion from the non-skin side in the thickness direction, the joining means is pressed at the portion overlapping the mark, and the joining means and the surface facing the joining means are crimped to each other. Therefore, the closing mechanism (joining means) can be crimped without opening and checking the skin side.

[0012] (Aspect 2) The absorbent article according to Aspect 1, wherein the joining means is provided on each of one side and the other side in the longitudinal direction, and the mark is provided on at least one of one side and the other side in the longitudinal direction.

[0013] According to Aspect 2, by pressing the joining means provided on at least one side of both sides in the longitudinal direction (both sides in the front-rear direction when folded), it is easy to crimp the joining means together.

[0014] (Aspect 3) The absorbent article according to Aspects 1 to 2, wherein one-side joining means and one-side mark are provided on the one side in the longitudinal direction, and the other-side joining means and the other-side mark are provided on the other side in the longitudinal direction.

[0015] According to Aspect 3, since the joining means (such as an adhesive) and the mark are provided on both sides in the longitudinal direction, it is easier to more firmly crimp the joining means together by pressing the mark portion from both sides.

[0016] (Aspect 4) The absorbent article according to either Aspect 1 or Aspect 3, wherein the one-side mark and the other-side mark are the same pattern.

[0017] According to Aspect 4, since the same mark is visible on both sides in the longitudinal direction (both sides in the front-rear direction when folded), the user can press without worrying about the front and back.

[0018] (Aspect 5) The absorbent article according to Aspects 1 to 4, wherein In the longitudinal direction, the one-side joining means and the one-side marker are spaced apart from the one end of the absorbent article, and the other-side joining means and the other-side marker are spaced apart from the other end of the absorbent article.

[0019] According to embodiment 5, since the joining means are spaced inward from the longitudinal ends, it is possible to suppress the joining means from protruding outward from the opposing end when being pressed together (resulting in weaker crimping). Also, since the markers are also located inward from the longitudinal ends, it is easier for the user to recognize the point to press (the markers are less likely to be interrupted).

[0020] (Appendix 6) An absorbent article described in any of Appendix 1 to Appendix 5, The size of the joining means and the size of the mark are different.

[0021] According to embodiment 6, if the mark is large, it is easier to press the entire joining means. If the mark is small, the joining means is pressed locally and the force is concentrated, making it easier to firmly press the two pieces together.

[0022] (Aspect 7) An absorbent article described in any of Aspects 1 to 6, In at least one of the longitudinal direction and the width direction, the length of the marker is shorter than the length of the joining means.

[0023] According to embodiment 7, the joining means is locally pressed and the force is concentrated, making it easy to achieve a firm bond.

[0024] (Appearance 8) An absorbent article described in any of Appearances 1 to 5, The joining means and the mark are of the same size.

[0025] According to embodiment 8, the entire joining means becomes easier to press, allowing for stable and secure bonding.

[0026] (Aspect 9) An absorbent article described in any of Aspects 1 to 8, When the mark is divided into three equal parts in the longitudinal direction into a first adjacent region, a central region, and a second adjacent region, the joining means and the central region overlap when viewed in the thickness direction in the unfolded and extended state.

[0027] According to embodiment 9, the central region where force is easily applied when pressing the marker overlaps with the joining means, so that the joining means is pressed efficiently and crimping is easier.

[0028] (Aspect 10) An absorbent article as described in Aspects 1 to 9, The mark has an indication that encourages pressing the absorbent article.

[0029] According to embodiment 10, the user can perform the operation of closing the absorbent article after use and pressing the joints together without hesitation.

[0030] (Aspect 11) An absorbent article described in any of Aspects 1 to 10, It has a leak-proof sheet laminated on the non-skin side of the absorbent core, The mark is provided on a sheet member laminated on the non-skin side of the aforementioned leak-proof sheet.

[0031] According to embodiment 11, when the mark is pressed, the pressing force is distributed more evenly due to the presence of the sheet member compared to when there is no sheet member, making it easier to apply force to a wider area of ​​the joining means.

[0032] (Aspect 12) An absorbent article described in any of Aspects 1 to 11, It has a leak-proof sheet laminated on the non-skin side of the absorbent core, When unfolded and extended, more than 80% of the area of ​​the leak-proof sheet has a single color.

[0033] According to embodiment 12, the visibility of the leak-proof sheet itself is suppressed, making it easier for the user to see the marker. In other words, because the visibility of the leak-proof sheet 3 itself is suppressed, it is easier for the user to see the marker 40, and the user's attention is less likely to be drawn to the leak-proof sheet 3.

[0034] (Aspect 13) An absorbent article described in any of Aspects 1 to 12, The mark is provided on the non-skin side of the leak-proof sheet.

[0035] According to embodiment 13, by providing a marker on the inconspicuous surface of the leak-proof sheet, the marker becomes more visible to the user. Furthermore, by printing the marker on the leak-proof sheet, a clearer and more stable marker can be formed than when printing the marker on nonwoven fabric or the like.

[0036] (Aspect 14) An absorbent article described in any of Aspects 1 to 12, The disposable diaper has a locking mechanism on the non-skin side that can be attached to the skin side, When viewed in the thickness direction in the unfolded and extended state, there is a portion where the locking means and the mark overlap.

[0037] According to embodiment 14, the overlap of at least a portion of the locking means and the marker makes the marker more conspicuous and easier for the user to see. Furthermore, when pressing the marker, it becomes easier to press at least a portion of the relatively rigid locking means, so the joining means is pressed more efficiently and crimped more easily compared to the case where the marker and the locking means do not overlap.

[0038] (Aspect 15) An absorbent article described in any of Aspects 1 to 12, The disposable diaper has a locking mechanism on the non-skin side that can be attached to the skin side, When viewed in the thickness direction in the unfolded and extended state, there is no overlapping portion between the locking means and the mark.

[0039] According to embodiment 15, it is possible to prevent the locking means (fastening tape, adhesive, etc.) from being pressed. This protects the locking means and minimizes the risk of injury to the user's fingers.

[0040] (Aspect 16) An absorbent article as described in any of aspects 15, In the longitudinal direction when the device is unfolded and extended, the marker is located outside the locking means.

[0041] According to embodiment 16, by pressing the joining means at a position as far outward as possible in the longitudinal direction (near the longitudinal end), the inner end of the absorbent article becomes less likely to curl up, and the absorbent article is more likely to maintain a closed state.

[0042] ===Implementation Method=== In this embodiment, an absorbent article will be described using a urine pad (hereinafter sometimes simply referred to as "pad") as an example. However, the absorbent article in this embodiment is not limited to a urine pad, and can also be applied to, for example, sanitary napkins, disposable panty-type diapers, shorts-type sanitary napkins, disposable tape-type diapers, pet diapers, absorbent sheets for nursing care or pets, etc.

[0043] <<<Basic configuration of urine absorption pad 1>>> First, let's explain the basic structure of the urine absorption pad 1. Figure 1 is a schematic plan view of the pad 1 in its unfolded and extended state, as seen from the skin side. Figure 2 is a schematic cross-sectional view of the pad 1. The urine absorption pad 1 can be used by placing it inside a pant-type or tape-type disposable diaper, or it can be used as a standalone pad by placing it directly inside the wearer's underwear (pants or shorts).

[0044] When unfolded, pad 1 has a roughly rectangular shape in plan view and has mutually perpendicular longitudinal, width, and thickness directions. The longitudinal direction follows the front-to-back direction from the wearer's abdomen to the back when pad 1 is worn. In the thickness direction, the side that contacts the wearer's skin is called the skin side, and the opposite side is called the non-skin side. Since pad 1 in this embodiment has a symmetrical configuration in the longitudinal direction, either side of pad 1 in the longitudinal direction may correspond to the wearer's abdomen. Also, unlike tape-type or pant-type diapers, pad 1 is worn without one end and the other end in the longitudinal direction being connected along the wearer's waist.

[0045] The unfolded state of pad 1 refers to the state in which the entire pad 1 is unfolded flat. The extended state of pad 1 refers to the state in which pad 1 is extended to the point in which wrinkles that were present on pad 1 are virtually invisible, and pad 1 is extended until the dimensions of each component constituting pad 1 (for example, the side sheet 4 described later) match or are close to the dimensions of the individual component.

[0046] The pad 1 comprises a liquid-absorbing core 10, a liquid-permeable surface sheet 2 (hereinafter sometimes referred to as top sheet 2) (e.g., nonwoven fabric) located on the skin side of the absorbent core 10, a liquid-impermeable back sheet 3 (e.g., a resin film such as polyethylene or polypropylene) located on the non-skin side of the absorbent core 10, and a pair of side sheets 4 provided on both sides of the pad 1 in the width direction. As shown in Figure 2, the pair of side sheets 4 are folded inward in the width direction from the width direction side of the non-skin side of the back sheet 3 toward the skin side of the skin side sheet 2, so as to wrap around the absorbent core 10.

[0047] An example of the absorbent core 10 is a liquid-absorbing fiber, such as pulp fiber containing SAP (superabsorbent polymer), molded into a predetermined shape. The absorbent core 10 is covered with a liquid-permeable core wrap sheet 11 (e.g., tissue). However, the absorbent core 10 is not limited to the above, and may be an SAP sheet in which an SAP layer is attached to a hydrophilic sheet, or an airlaid sheet in which liquid-absorbing fibers are molded into a sheet by the airlaid method, or it may be a configuration of two or more layers. Furthermore, the absorbent core 10 does not have to be covered with the core wrap sheet 11.

[0048] Furthermore, a fixing member 20 is provided on the non-skin side of the pad 1, serving as a fastening means that allows the pad 1 to be fastened to the skin side (inner side) of a pant-type diaper, underwear (outer garment), or disposable diaper. In Figure 1, for example, fixing members 20 are provided at both ends of the pad 1 in the longitudinal direction. The fixing member 20 is, for example, a rectangular member, and its long side is provided so as to be aligned with the width direction of the pad 1. The fixing member 20 is preferably a member that can be peeled off from the inner side of the outer garment without damaging the outer garment and can be reattached. In this embodiment, the fixing member 20 is a tape with a hook material (for example, the male part of a hook-and-loop fastener). Other examples of fixing members 20 include tape coated with adhesive. Note that the fixing member 20 may not be provided.

[0049] Furthermore, the pad 1 has a pair of leg-circumference elastic members 5 provided along the longitudinal direction on both sides in the width direction. In Figure 2, the leg-circumference elastic members 5 are fixed in an extended state in the longitudinal direction between the back sheet 3 and the side sheet 4. This makes it easier for both sides of the pad 1 in the width direction to conform closely to the wearer's legs.

[0050] Furthermore, the pad 1 has a pair of leak-proof wall portions 6 on both sides in the width direction that can be raised toward the skin. The leak-proof wall portion 6 comprises a side sheet 4 and a leak-proof wall elastic member 7. Both ends in the longitudinal direction are fixed to the surface sheet 2 by adhesive areas 8. The leak-proof wall elastic member 7 is fixed to the inner end of the side sheet 4 in the width direction in an extended state along the longitudinal direction of the pad 1. When the pad 1 is worn, the tip of the leak-proof wall portion 6 rises toward the skin based on the elasticity of the leak-proof wall elastic member 7, and the lateral leakage of excretory fluids, etc. is suppressed by the raised leak-proof wall portion 6.

[0051] Furthermore, the pad 1 has connecting means 30, 30' on the skin-facing side at both ends in the longitudinal direction, and has markings 40, 40' that are visible from the non-skin side. The details of their configuration will be described below.

[0052] <<<Joining means 30, 30'>>> As shown in Figure 1, one end of the pad 1 in the longitudinal direction is provided with a one-side joining means 30 on the skin-facing side (surface sheet 2) of the pad 1, which serves as a closing mechanism. The other end of the pad 1 in the longitudinal direction is provided with a other-side joining means 30' on the skin-facing side (surface sheet 2) of the pad 1. The other-side joining means 30' is part of the pad 1. When discarding the pad, the one-side joining means 30, as a joining means, can be joined to the other-side joining means 30', which is part of the pad 1. In this embodiment, the joining means 30 and 30' are regions in which an adhesive (such as a self-adhesive adhesive described later) is provided in at least a portion of the area.

[0053] Figure 3 shows the state when pad 1 is folded in half along its longitudinal direction. Specifically, the folded state is the state in which pad 1 is folded along the center line CL in the longitudinal direction, that is, the pad 1 is divided into two equal parts along its longitudinal direction and folded along the center line CL (hereinafter sometimes referred to as the fold line FL) along the width direction. This state is, for example, the state of pad 1 before use or the state when it is disposed of after use. Figure 3A is a plan view of pad 1 in the state when it is folded in half along its longitudinal direction, and Figure 3B is a schematic cross-sectional view of pad 1 when it is folded in half with the ends of pad 1 closed and viewed from the width direction. As shown in Figures 3A and 3B, when pad 1 is folded in half along its longitudinal direction, one-side joining means 30 and the other-side joining means 30' are arranged to overlap and face each other in the thickness direction so that they can be joined.

[0054] Figure 4 is a partially enlarged view illustrating the details of the configuration of pad 1. While the position of the one-sided joining means 30 in the longitudinal direction will be described, since pad 1 is symmetrical in the longitudinal direction, the configuration of the other-sided joining means 30' is the same as that of the one-sided joining means 30. The one-sided joining means 30 is provided at the end of pad 1 in the longitudinal direction, and at a predetermined distance d1 from the end of pad 1 in the longitudinal direction. The region extending in the width direction at a predetermined distance d1 from the end of pad 1 in the longitudinal direction to the one-sided joining means 30 is also called the dry edge D. The dry edge D is the non-adhesive region from the end of pad 1 to the one-sided joining means 30 where no adhesive is provided.

[0055] The one-sided joining means 30 and the other-sided joining means 30' each have a self-adhesive adhesive 31 (hereinafter sometimes referred to as self-adhesive or self-adhesive bonding agent) as a joining portion. Note that the bonding agent in this embodiment is not limited to a self-adhesive bonding agent, but may also be an adhesive.

[0056] Figure 5 (Figures 5A and 5B) is an explanatory diagram of the one-sided joining means 30 and the other-sided joining means 30'. The adhesive 31, which serves as a joining portion provided on the one-sided joining means 30 and the other-sided joining means 30', has low tackiness (adhesion) of its own, but exhibits adhesive force (hereinafter referred to as joining force) when the adhesive 31s are brought into contact with each other under relatively weak pressure. As shown in Figure 5A, when the one-sided joining means 30 and the other-sided joining means 30' are pressed together, the one-sided joining means 30 and the other-sided joining means 30' stick together (joint force is exhibited) due to their respective adhesives 31. On the other hand, as shown in Figure 5B, when the adhesive 31 comes into contact with a nonwoven fabric provided on the pad 1 or with a material other than the adhesive 31, such as skin, the one-sided joining means 30 does not easily stick to the material it comes into contact with.

[0057] The bonding force between the adhesive 31 and the other members is preferably 1 / 4 or less of the bonding force between the adhesive 31s themselves. More preferably, the bonding force between the adhesive 31 and the other members is 1 / 10 or less of the bonding force between the adhesive 31s themselves. Furthermore, when the adhesive 31s are brought into contact with each other, they can be separated without damaging the adhesive 31s, and can be re-bonded by bringing them into contact again after separation. By using the adhesive 31, the bonding means 30 can be made flexible with low rigidity, thereby suppressing discomfort when wearing the pad 1.

[0058] The adhesive 31 is not particularly limited as long as it is safe to come into contact with the wearer's skin, and examples include emulsion-type self-adhesives (emulsion inks) and hot-melt self-adhesives (HMAs). As the main component of the emulsion-type self-adhesive, it can be used by mixing natural rubber, synthetic rubber, etc. with emulsifiers, etc., and those disclosed in Japanese Patent No. 2589307 and Japanese Patent Application Publication No. 2005-095381 may be used. As the main component of the hot-melt self-adhesive, it can be used by heating and melting thermoplastic resins such as polyolefins and polyamides, as disclosed in Japanese Patent No. 7476348 and Japanese Patent No. 7543716. In this embodiment, an emulsion-type self-adhesive is used.

[0059] Next, the specific configurations of the one-sided joining means 30 and the other-sided joining means 30' will be explained in detail using Figure 6. Figure 6 is a diagram illustrating the joining means 30 and 30'. For the sake of brevity, only the one-sided joining means 30 will be described, but the other-sided joining means 30' has a similar configuration.

[0060] As shown in Figure 6, the one-sided joining means 30 and the other-sided joining means 30' are quadrilateral regions that circumscribe the portion to which the self-adhesive adhesive 31 is applied as the joining area. In Figure 6, the region to which the self-adhesive adhesive 31 is applied is shown as a lightly filled area.

[0061] As mentioned above, in this embodiment, an emulsion-based self-adhesive agent is used as the bonding agent 31. Furthermore, one application is defined as applying the bonding agent 31 uniformly in a roughly rectangular shape that is long in the width direction (so-called solid coating), and in the example shown in Figure 6, it is applied repeatedly three times. By applying the bonding agent 31 in multiple layers in the thickness direction, the bonding strength when bonding agents 31 are joined together can be increased compared to the case of a single application. Note that although three applications are used in this embodiment, it is not limited to this.

[0062] In this embodiment, as shown in Figure 6, the application positions of the adhesive 31 are offset in the longitudinal and width directions. Therefore, as shown in the thickness direction diagrams (lower side view and right side view) of Figure 6, the amount of adhesive 31 applied per unit area (basis weight or basis weight) in the first adjacent regions L1 and W1 adjacent to one of the central regions Lc and Wc, and in the second adjacent regions L2 and W2 adjacent to the other, is less than the amount of adhesive 31 applied per unit area in the central regions Lc and Wc. In other words, since the amount of adhesive 31 applied per unit area is less than in the central regions Lc and Wc, the bonding strength is also lower than in the central regions Lc and Wc.

[0063] Furthermore, the surface of the one-sided joining means 30 has protrusions 32 and recesses 33 formed due to differences in the amount of adhesive 31 applied per unit area. The protrusions 32 are the first portion 34, where the amount of adhesive 31 applied per unit area is greater than the surrounding area, and this portion has been applied three times out of three applications. On the other hand, the recesses 33 are the second portion 35, where the amount applied is less than the surrounding area. Thus, the first portion 34 is thicker in the thickness direction because the amount of adhesive 31 applied per unit area is greater, while the second portion 35 is thinner because the amount is less than that of the first portion 34. Note that there may be other methods for forming the protrusions 32 and recesses 33 on the surface of the one-sided joining means 30. For example, the surface of the surface sheet 2 may be made uneven so as to form irregularities on the surface of the adhesive 31 applied to the surface sheet 2, or the irregularities may be formed by compressing a portion of the applied adhesive 31.

[0064] <<<Landmark 40, 40'>>> Next, the specific configuration of the marker 40 will be described. Figure 7 is a schematic plan view of the pad 1 of this embodiment as seen from the non-skin side when it is unfolded and extended. As shown in Figure 7, the pad 1 has a marker 40 that is visible from the non-skin side. In addition, when the pad 1 is unfolded and extended and viewed in the thickness direction, there is a portion where the joining means 30 and the marker 40 overlap.

[0065] In this embodiment, the marker 40 is provided on the non-skin side of the leak-proof sheet 3. The pad 1 has a one-side marker 40 corresponding to the one-side joining means 30 on one side in the longitudinal direction, and a other-side marker 40' corresponding to the other-side joining means 30' on the other side in the longitudinal direction. In Figure 7, the markers 40 and 40' have indications (such as "Press") that encourage pressing the pad 1. Furthermore, the one-side marker 40 and the other-side marker 40' have the same design (color, shape, text information, etc.). However, the configuration is not limited to the above, and the marker 40 may be provided on at least one of the one and the other sides in the longitudinal direction of the pad 1.

[0066] Furthermore, in the longitudinal direction of the pad 1, the one-sided joining means 30 and the one-sided marker 40 are spaced apart from one end of the pad 1, and the other-sided joining means 30' and the other-sided marker 40' are spaced apart from the other end of the pad 1. In Figure 7, the joining means 30 and 30' are provided at positions located at a predetermined distance d1 from both ends of the pad 1, as described above, and the markers 40 and 40' are provided at positions located at a predetermined distance d2 from both ends of the pad 1. Note that, as shown in Figure 7, the predetermined distances d1 and d2 in this embodiment are equal, but are not limited to this.

[0067] Furthermore, in this embodiment, when the pad 1 is unfolded and extended, the markings 40 and 40' do not have any overlapping portions with the fixing members 20, which serve as locking means provided at both ends, when viewed in the thickness direction. Also, as shown in Figure 7, the center position CL40 of the markings 40 and 40' is located further outward in the longitudinal direction than the center position CL20 of the fixing member 20. However, the configuration is not limited to the above.

[0068] Next, the operation and effects of the pad 1 of this embodiment will be explained using Figures 7 and 3B. When disposing of a used pad 1, first fold the pad 1 along the center line CL (fold line FL) with the skin side facing inward. Then, overlap the fastening means 30 (30') so that they face each other and press from the non-skin side (see Figure 3B). At this time, because the fastening means 30 (30') is provided on the skin side, it was difficult to recognize the position of the fastening means 30 (30') from the outside (non-skin side), and it was sometimes difficult to sufficiently press the fastening means 30 (30') into place. In addition, when trying to open the skin side to check the position of the fastening means 30 (30'), hygiene and odor problems arose.

[0069] In contrast, in this embodiment, when the pad 1 is folded with the skin-side surface facing inward for disposal, pressing the marks 40 and 40' from the non-skin side in the thickness direction presses the joining means 30 (30') in the portion overlapping with the marks 40 and 40', causing the one-side joining means 30 and the surface facing the one-side joining means 30 (the other-side joining means 30' in Figure 3B) to be pressed together. Therefore, the joining means 30 (30') as a closing mechanism can be pressed together without opening and checking the skin-side surface.

[0070] Furthermore, the pad 1 has a mark 40 on one side and a mark 40' on the other side at both ends in the longitudinal direction of the pad. That is, when the pad 1 is folded in half after use, the marks 40 and 40' are provided on both sides of the folded pad 1 (both sides in the longitudinal direction when folded), so that the marks 40 and 40' are easy for the user to see and confirm. This makes it easier to press the parts marked 40 and 40' from both sides, making it easier to press the joining means 30 (30') together more firmly.

[0071] In this embodiment, the marker 40 may be located on at least one side of both ends in the longitudinal direction of the pad 1. In this case, the joining means 30 (30') provided on both sides in the longitudinal direction of the folded pad 1 can be easily pressed together by pressing them from at least one side. Furthermore, if the marker 40 is located on only one side in the longitudinal direction of the pad 1, the cost of providing the other side marker 40' can be reduced. In this embodiment, the pad 1 has a symmetrical configuration in the longitudinal direction, but is not limited to this. For example, the pad may have a front-to-back direction in the longitudinal direction when worn, and the marker 40 may be located on only one side in the front-to-back direction in the longitudinal direction of the pad 1. In this case, the user can easily recognize the front-to-back direction when the pad 1 is folded.

[0072] Furthermore, since the markers 40 and 40' in this embodiment have indicators that prompt the user to press the pad 1, the user can perform the operation of closing the pad 1 after use and pressing the joining means 30 (30') without hesitation. In Figure 7, the marker is shown as "press," but it is not limited to this, and may be a diagram, shape, text information, etc., as shown in Figure 10 described later.

[0073] Furthermore, because the markings 40 on one side and 40' on the other side have the same design, the same marks 40 and 40' are visible on both sides of the folded pad 1 in the longitudinal direction, allowing the user to press without worrying about the front or back.

[0074] Furthermore, the markers 40 and 40' in this embodiment are spaced apart from the longitudinal ends of the pad 1, respectively. In other words, since the joining means 30 (30') is spaced inward from the longitudinal ends, it is possible to prevent the joining means 30 (30') from protruding outward from the opposing end (resulting in weaker compression) when it is pressed. Moreover, since the markers 40 and 40' are also spaced inward from the longitudinal ends, it is easier for the user to recognize the area to be pressed. For example, since the markers 40 and 40' are less likely to be interrupted in the longitudinal direction, they can be more clearly recognized by the user.

[0075] Furthermore, in this embodiment, the markers 40 and 40' do not have any overlapping portions between the fixing members 20 provided at both ends and the markers 40 and 40' when viewed in the thickness direction of the pad 1 (see Figures 3B, 4, etc.). This prevents the fixing means 20 from being accidentally pressed, thereby protecting the fixing means 20 and minimizing the risk of injury to the user's fingers.

[0076] Furthermore, the center position CL40 of the markers 40 and 40' is located further outward in the longitudinal direction than the center position CL20 of the fixing member 20 (see Figure 7). By pressing the joining means 30 (30') as far outward as possible in the longitudinal direction (near the longitudinal end), the longitudinal end becomes less likely to curl up, and the pad 1 is more likely to remain closed.

[0077] Furthermore, in this embodiment, the size of the joining means 30 (30') and the sizes of the markers 40, 40' may be different. Figure 8 is an explanatory diagram of the size relationship between the markers 40, 40' and the joining means 30, 30'. Figures 8 to 11, described later, are partially enlarged views of the pad 1 as seen from the non-skin side, where the horizontal direction of the paper is the width direction of the pad 1 and the vertical direction is the longitudinal direction of the pad 1. Also, for the sake of brevity, only the one-sided marker 40 and the one-sided joining means 30 will be described, but a similar configuration can be used even if there is a other-sided marker 40' and a other-sided joining means 30'. In Figure 8A, the size of the marker 40 is smaller than the size of the joining means 30. If the marker 40 is small, the joining means 30 is pressed locally and the force is concentrated, making it easier to firmly press it. On the other hand, in Figure 8B, the size of the marker 40 is larger than the size of the joining means 30. If the marker 40 is large, it will be more noticeable and easier for the user to see. In addition, it will be easier to press the entire joining means 30, allowing for stable crimping.

[0078] In this embodiment, the length of the marker 40 may be shorter than the length of the joining means 30 in at least one of the longitudinal and width directions of the pad 1. For example, in Figure 8C, the marker 40 is longer in the longitudinal direction and shorter in the width direction than the longitudinal / width direction length of the joining means 30. In this case, the longitudinal direction of the joining means 30 is more easily pressed locally, making it easier to firmly press it in the longitudinal direction. On the other hand, in Figure 8D, the marker 40 is shorter in the longitudinal direction and longer in the width direction than the longitudinal / width direction length of the joining means 30. In this case, the width direction of the joining means 30 is more easily pressed locally, making it easier to firmly press it in the width direction.

[0079] Furthermore, as shown in Figure 8E, the joining means 30 and the marker 40 may be the same size. Doing so suppresses excessive pressing on areas without the joining means 30, and makes it easier to press the entire joining means 30, allowing for stable bonding.

[0080] Figure 9 is an explanatory diagram of the positional relationship between the markers 40, 40' and the joining means 30, 30'. In this embodiment, when the marker 40 (40') is divided into three equal parts in the longitudinal direction of the pad 1 into a first adjacent region M1, a central region Mc, and a second adjacent region M2, the joining means 30 (30') and the central region Mc overlap when viewed in the thickness direction in the unfolded and extended state of the pad 1. Specifically, as shown in Figure 9A, the marker 40 and the joining means 30 overlap in the longitudinal / width direction, and the joining means 30 overlaps with the central region Mc of the marker 40. With this configuration, the central region Mc, where force is easily applied when pressing the marker 40, overlaps with the joining means 30, allowing the joining means 30 to be pressed more efficiently and making it easier to apply pressure.

[0081] Furthermore, in Figure 9A, the central region Mc, where force is easily applied when pressing the marker 40, overlaps in the thickness direction with the central region Lc of the joining means 30. As a result, the central region Lc of the joining means 30 is pressed more efficiently, making it easier to bond.

[0082] Furthermore, the configuration is not limited to that shown in Figure 9A. For example, as shown in Figure 9B, the marker 40 and the joining means 30 may be offset in the longitudinal direction, and there may be an overlapping portion between the joining means 30 and the central region Mc of the marker 40. Even in this case, because the central region Mc, where force is easily applied when pressing the marker 40, overlaps with the joining means 30, the joining means 30 is pressed more efficiently, making it easier to crimp.

[0083] On the other hand, in Figure 9C, the marker 40 and the joining means 30 are offset from each other in the longitudinal direction, and there is no overlap between the central region Mc of the joining means 30 and the marker 40. In this case, since the central region Mc, where force is easily applied when pressing the marker 40, does not overlap with the joining means 30, the joining means 30 may not be pressed efficiently, making it difficult to crimp.

[0084] ===Modifications of Markers 40 and 40'=== In this embodiment, the markers 40 and 40' are printed or coated with colored ink on the surface of the leak-proof sheet 3, as explained in Figure 7, but are not limited to this. Figure 10 is an explanatory diagram of a modified example of the markers 40 and 40'. For example, as shown in Figures 10A to 10D, the markers 40 may be provided on a sheet member 41 laminated on the non-skin side of the leak-proof sheet 3. In that case, when the markers 40 are pressed, the pressing force is dispersed by the presence of the sheet member 41 compared to when the sheet member 41 is not present, making it easier to apply force to a wider area of ​​the joining means 30.

[0085] Furthermore, the design of the marker 40 should preferably be a display that encourages the user to press down on the pad 1, as shown in the examples in Figures 10A to 10D. Figure 10A shows the word "push" and an arrow indicating the area to press. Figure 10B highlights the area that the user should press down with a graphic, and the sheet member 41 is formed in a distinctive shape that is easily noticeable, rather than being a rectangle. Figure 10C has the words "Please press" written in large letters encouraging the user to press down. Figure 10D is an example where the word "PUSH" (the English spelling of "push") is placed in the center, and graphics are used to highlight both sides of the word. In addition, messages for the user (for example, infants or their guardians) may also be displayed. In all of these examples, the design of the marker 40 (color, shape, and text information) allows the user to close the pad 1 after use and press down on the joining means 30 (30') without hesitation.

[0086] Furthermore, when the pad 1 is unfolded and extended, the markers 40 and 40' may have portions that overlap with the fixing member 20, which serves as a locking means, when viewed in the thickness direction. Figure 11 is an explanatory diagram (schematic plan view) of the case where the marker 40 and the fixing member 20 overlap. As shown in Figure 11, in a plan view of the pad 1, at least a portion of the marker 40 and the fixing member 20 overlap, and furthermore, at least a portion of the marker 40 and the joining means 30 overlap. In this case, the marker 40 is more conspicuous and easier for the user to see. Also, when pressing the marker 40, it becomes easier to press at least a portion of the relatively rigid fixing member 20, so the joining means 30 is pressed more efficiently and easier to crimp compared to the case where the marker 40 and the fixing member 20 do not overlap. Furthermore, the marker 40 may be printed on the skin side of the fixing member 20 and be visible from the non-skin side of the pad 1. In that case, the size of the marker 40 and the fixing member 20 may be equal.

[0087] ===About Leak-Proof Sheet 3=== In this embodiment, it is desirable that 80% or more of the area of ​​the leak-proof sheet 3 has a single color when the pad 1 is unfolded and extended. Figure 12 is an explanatory diagram of the leak-proof sheet 3. As shown in Figure 12A, the leak-proof sheet 3 of this embodiment is a single color with a white background, so the user will notice the marker 40 and will be able to easily see the marker 40. In other words, by making the leak-proof sheet 3 itself inconspicuous, the user will be able to easily see the marker 40, and the user's attention will not be drawn to the leak-proof sheet 3.

[0088] On the other hand, in Figure 12B, a large stripe pattern is applied to a wide area of ​​the leak-proof sheet 3. Furthermore, in Figure 12C, pictures and marks such as flowers and stars are applied to a wide area of ​​the leak-proof sheet 3. In these examples of Figures 12B and 12C, the leak-proof sheet 3 itself is conspicuous, which may make it difficult for the user to see the marker 40. In other words, the user's attention may be more easily drawn to the leak-proof sheet 3.

[0089] In this embodiment, as shown in Figure 12A, the background is a single color white, but it is not limited to this; for example, it could be a light blue background or a light green background. The point is that if the marker 40 is more conspicuous than the background (in this case, the leak-proof sheet 3), it will be easily visible to the user, so it is desirable that more than 80% of the area of ​​the leak-proof sheet 3 has a single color.

[0090] Furthermore, the pad 1 of this embodiment has markings 40 and 40' on the surface (non-skin side) of the inconspicuous leak-proof sheet 3, as shown in Figure 12A. As a result, the user can more easily see the markings 40 and 40' when folding the pad after use. Moreover, by printing the markings 40 and 40' on the leak-proof sheet 3 (for example, a film), clearer markings can be reliably formed than when printing the markings 40 and 40' on a nonwoven fabric or the like.

[0091] <<<Regarding the bonding force of bonding means 30 and 30' as bonding means>>> Figure 13 is a diagram illustrating the operation and effect of pad 1 to which the markers 40, 40' and joining means 30, 30' are applied. Figure 13A is a view from the thickness direction of pad 1 when it is folded in half along the fold line FL so that one joining means 30 and the other joining means 30' face each other, and the two halves are glued together. Figure 13B is a diagram showing the process of separating one joining means 30 and the other joining means 30' when unfolding pad 1.

[0092] As shown in Figure 13A, in this embodiment, when the pad 1 is folded in half along the center line CL (fold line FL), the central region Lc of the one-sided joining means 30 and the central region Lc' of the other-sided joining means 30' overlap in the thickness direction. Although not shown, in the width direction as well, the central region Wc of the one-sided joining means 30 and the central region Wc' of the other-sided joining means 30' overlap.

[0093] The one-sided joining means 30 is divided into three equal parts in the longitudinal direction and the width direction. In the longitudinal direction, these are the first longitudinal adjacent region L1, the longitudinal central region Lc, and the second longitudinal adjacent region L2, starting from one side. In the width direction, these are the first width adjacent region W1, the width central region Wc, and the second width adjacent region W2. (See Figure 6) There are differences in joining strength among these regions. In this embodiment, the joining strength of the first adjacent regions L1 and W1, which are adjacent to one side of the central regions Lc and Wc, is weaker than the joining strength of the central regions Lc and Wc in the longitudinal and width directions. Furthermore, the joining strength of the second adjacent regions L2 and W2, which are adjacent to the other side of the central regions Lc and Wc, is weaker than the joining strength of the central regions Lc and Wc.

[0094] The magnitude of the bonding force in each region, such as the first longitudinal adjacent region L1 and the longitudinal central region Lc, can be evaluated by the amount (basis weight) of the adhesive 31 per unit area provided as a bonding part in each region. In each region, the greater the amount (basis weight) of the adhesive 31 per unit area, the greater the bonding force. Furthermore, for example, if a hook-and-loop fastener 36, described later, is used as a bonding part instead of the adhesive 31, and some of the hook portions of the hook-and-loop fastener 36 are flattened by embossing or the like, the bonding force can be evaluated by the amount (number) of hook portions per unit area that maintain their function as hooks (unflattened hook portions) in each region.

[0095] Alternatively, the magnitude of the bonding force in each region may be evaluated using a measuring instrument.

[0096] When measuring the magnitude of the bonding force in the first longitudinal adjacent region L1, the longitudinal central region Lc, and the second longitudinal adjacent region L2, two sample pieces are prepared. The first sample piece is a cut-out of the region to be measured from the first longitudinal adjacent region L1, the longitudinal central region Lc, etc. The second sample piece is a nonwoven fabric to which a uniform amount of bonding agent 31 has been applied.

[0097] By attaching masking tape to the end of the sample piece, a holding portion (grasping portion) is formed at the end of the sample piece. Next, the two sample pieces are placed on top of each other, and the two sample pieces are joined together by rolling a 2kg roller at 5mm / second from the opposite side of the holding portion.

[0098] Next, the sample piece is held in the chuck of a tensile testing machine (for example, an Instron universal material testing machine), and the two sample pieces are separated by pulling the two holding parts apart in the longitudinal direction. The tensile load at the time of separation is then measured. The average value of the tensile load represents the magnitude of the bonding force in the area being measured. The joint strength can be measured in the same manner for the first adjacent width region W1, the central width region Wc, and the second adjacent width region W2.

[0099] Before use (during packaging), the pad 1 is closed, and for example, as shown in Figure 13A, the one-sided joining means 30 and the other-sided joining means 30' are in contact. When using the pad 1, as shown in Figure 13B, the user grasps the areas of the dry edges D provided at both ends in the longitudinal direction of the pad 1 and peels it off towards the center in the longitudinal direction.

[0100] In this case, if the bonding force at the point where the peeling begins is strong, it may be difficult to open when unfolding, and this may be particularly difficult for elderly users with reduced dexterity in their fingers. However, in the pad 1 of this embodiment, the bonding force of the first longitudinal adjacent regions L1 and L1' in the one-side bonding means 30 is weaker than the bonding force of the longitudinal central regions Lc and Lc'. Therefore, it can be peeled and unfolded with relatively less force compared to when the bonding force of the first longitudinal adjacent regions L1 and L1' in the one-side bonding means 30 is stronger than, or the same as, the bonding force of the longitudinal central regions Lc and Lc'. Furthermore, because a dry edge D is provided, it is easier for the user to grasp and even easier to peel off.

[0101] In this embodiment, since the second adjacent region L2 with weak bonding force is located on the longitudinal centerline CL side, the pad 1 can also be peeled away from the leg-around elastic member 5 toward the end. In this case as well, the same effects as described above are achieved. Furthermore, since a dry edge D is provided over a predetermined distance d1 from the end in the width direction of the pad 1, the ease of peeling can be improved even when performing such peeling.

[0102] Furthermore, the central region (first portion 34) of both the one-sided joining means 30 and the other-sided joining means 30' has a stronger joining force than the adjacent region. As a result, when the pad 1 is folded in half along the fold line FL after use or disposal, it is easier to maintain the state in which the pad 1 covers the excrement on the side of the skin by bringing one end of the pad 1 into contact with the other end.

[0103] Furthermore, the configuration is not limited to the above. The coating amount in either the first adjacent region L1, W1 or the second adjacent region L2, W2 may be less than that in the central region Lc, Wc. Alternatively, the difference in coating amount may be in only one of the directions, either the longitudinal or the width. For example, the coating amount in the second adjacent region L2 (second longitudinal adjacent region) in the longitudinal direction may be less than that in the central region Lc. In this case, when the user peels off the pad 1, they can easily unfold it by peeling it off from the second adjacent region L2, which has weaker bonding force.

[0104] Furthermore, in the pad 1 of this embodiment, when the pad 1 is folded in half along the center line CL (fold line FL), the central regions Lc and Wc of the one-sided joining means 30 and the central regions Lc' and Wc' of the other-sided joining means 30' overlap in the thickness direction. Because the central regions overlap, when disposing of the pad 1, it is easier to maintain the state in which the pad 1 is folded in half and covers the excrement on the side of the skin with the pad 1.

[0105] Furthermore, the same effect and benefits can be achieved even when the pad 1 is folded in half at the center position in the width direction (a fold line along the center line in the width direction). In this case, two joining means should be provided on one side and the other side in the width direction, with the center line in the width direction as the reference.

[0106] Alternatively, the joining means 30 on one side may have varying degrees of joining force, while the joining means 30' on the other side may have a uniform joining force.

[0107] Furthermore, regarding the magnitude of the joining force in the longitudinal and width directions of the one-sided joining means 30, the value obtained by dividing the difference between the joining force of the longitudinal central region Lc and the joining force of the first longitudinal adjacent region L1 by the longitudinal length of the longitudinal central region Lc is greater than the value obtained by dividing the difference between the joining force of the width central region Wc and the joining force of the first width adjacent region W1 by the width direction length of the width central region Wc. In other words, the difference in joining force per unit length is greater in the longitudinal direction than in the width direction.

[0108] In the longitudinal direction, the difference in bonding force per unit length between the central region Lc(Lc') and the adjacent region L1(L1') is large. Therefore, even when the pad 1 is folded along the fold line FL in the width direction before use, and the one-sided bonding means 30 and the other-sided bonding means 30' of the pad 1 are joined, it is possible to easily separate the one-sided bonding means 30 and the other-sided bonding means 30' and unfold the pad in the longitudinal direction. On the other hand, as shown in the configuration of Figure 6, in the width direction, the difference in bonding force per unit length between the central region Wc(Wc') and the adjacent region W1(W1') is small. Therefore, when discarding the pad 1, it is possible to easily maintain the state in which the excrement on the skin side is covered by the pad 1 by joining the one-sided bonding means 30 and the other-sided bonding means 30' provided on the skin side.

[0109] Furthermore, in this embodiment, the pad 1 is made possible by providing a first portion 34 and a second portion 35 that is thinner than the first portion 34 on the joining means 30 and 30', thereby forming convex and concave portions. As a result, when the joining means 30 on one side and the joining means 30' on the other side of the pad 1 are joined before use, the joining means 30 on one side and the joining means 30' on the other side can be easily separated and unfolded in the longitudinal direction. In other words, by forming irregularities with the adhesive 31, the concave portion 33, which is thinner in the thickness direction, can be made easier to separate.

[0110] The joining means is not limited to the adhesive 31. For example, a hook-and-loop fastener can be provided on at least one of the skin-facing sides of the pad 1 in the joining means 30. In that case, a similar effect can be achieved by forming a convex portion and a concave portion on the joining surface of the hook-and-loop fastener. Specifically, when hook-and-loop fasteners are provided so as to face each other at both ends of the skin-facing side of the pad 1, it is possible to make it easier to peel one hook-and-loop fastener from the other by providing a high portion (convex portion) and a low portion (concealed portion) on the hook of the hook-and-loop fastener. Similarly, when a hook-and-loop fastener is placed on only one end and the other end is made of nonwoven fabric (surface sheet 2), it is possible to make it easier to peel the hook-and-loop fastener from the surface sheet 2, which is part of the pad 1, by forming a convex portion and a concave portion on the hook-and-loop fastener.

[0111] Furthermore, in the pad 1 of this embodiment, since the joining means 30 and 30' are provided at the ends of the pad 1, it is easier to peel off and more difficult to open when disposing of the pad than when the joining means 30 and 30' are provided in the center.

[0112] ===Modified versions of joining means 30, 30'=== Figure 14 is an explanatory diagram showing modified examples of the joining means 30 and 30' of the pad 1. It is desirable that the self-adhesive adhesive 31 in the joining means 30 and 30' be provided in a non-uniform pattern on the skin side of the surface sheet 2. An example of such a configuration is shown in Figures 14A and 14B. Figures 14A and 14B show self-adhesive quadrilateral joining means 30 and 30', respectively.

[0113] In the modified example shown in Figure 14A, the longitudinal central region Lc is an area on the skin-side surface sheet 2 where the adhesive 31 is applied uniformly in a roughly rectangular shape that is long in the width direction (so-called solid coating). In addition, the first longitudinal adjacent region L1 and the second longitudinal adjacent region L2 are coated with the self-adhesive adhesive 31 in a wave-like pattern, as shown in Figure 14A.

[0114] In this case, compared to the case where the self-adhesive adhesive 31 is applied evenly to the surface sheet 2 (uniform pattern), the total amount (basis weight) of the self-adhesive adhesive 31 can be reduced. Furthermore, the bonding strength of the first longitudinal adjacent region L1 and the second longitudinal adjacent region L2, which have margins due to the application of the self-adhesive adhesive 31 in a wave-like pattern, is weaker than that of the longitudinal central region Lc, which is applied evenly. As a result, while ensuring ease of peeling when unfolding the pad 1, the bonding strength of the longitudinal central region Lc is stronger than that of the adjacent regions, so that when folding the pad 1 for disposal, the excrement on the side of the skin can be kept covered by the pad 1.

[0115] Next, in the modified example shown in Figure 14B, the longitudinal central region Lc is a uniformly coated area, similar to the modified example in Figure 14A. Then, as shown in Figure 14B, the first longitudinal adjacent region L1 and the second longitudinal adjacent region L2 have the self-adhesive bonding agent 31 partially applied in the width direction, leaving a blank area.

[0116] In this case, similar to the modified example in Figure 14A, the total amount of self-adhesive adhesive 31 applied (basis weight) can be reduced compared to the case where the self-adhesive adhesive 31 is applied evenly to the surface sheet 2 (uniform pattern). Furthermore, the bonding strength of the first longitudinal adjacent region L1 and the second longitudinal adjacent region L2, which have margins due to the self-adhesive adhesive 31 being applied only to a portion of the width direction, is weaker than that of the longitudinal central region Lc, which is fully coated. As a result, while ensuring ease of peeling when unfolding the pad 1, the bonding strength of the longitudinal central region Lc is stronger than that of the adjacent regions, so that when folding the pad 1 for disposal, the excrement on the side of the skin can be kept covered by the pad 1.

[0117] The joining means 30 in Figure 14C has a hook-and-loop fastener 36. In the modified example of Figure 14C, the longitudinal central region Lc is a region where the hook-and-loop fastener 36 is uniformly arranged, and the first longitudinal adjacent region L1 and the second longitudinal adjacent region L2 are configured such that some of the hook portions of the hook-and-loop fastener 36 are flattened by embossing 37 or the like, as shown in Figure 14C, thereby rendering them unusable as hooks.

[0118] In this case, the bonding force of the first longitudinal adjacent region L1 and the second longitudinal adjacent region L2, where some of the hook portions of the hook fastener 36 are crushed by embossing 37 or the like to eliminate the hook function, is weaker than that of the longitudinal central region Lc, where the hook portions are not crushed. As a result, while ensuring ease of peeling when deploying the pad 1, the bonding force of the longitudinal central region Lc is stronger than that of the adjacent regions, so that when folding the pad 1 for disposal, the excrement on the side of the skin can be kept covered by the pad 1.

[0119] In these modified examples, the amount of coating per unit area and the arrangement pattern of the bonding means 30, 30' in the central regions Lc, Wc differ from the arrangement pattern of the bonding means 30, 30' in the first adjacent regions L1, W1 or the second adjacent regions L2, W2.
