[[TECHNICAL FIELD]]

[0001] The present disclosure relates to a disposable paper diaper that is excellent in fit when put on by a wearer alone, as well as in adjustability for close contact with the body and wearing comfort. [[BACKGROUND ART]]

[0002] Patent Document 1 discloses a pants-type disposable diaper. The diaper includes an absorbent main body, a crotch outer cover portion, a front body portion, and a back body portion. The crotch outer cover portion, the front body portion, and the back body portion correspond to an outer cover member and are joined to the absorbent main body. The front body portion and the back body portion are connected in an annular shape, whereby the diaper is in a pants-type form with a waist opening and a pair of leg openings formed therein. [[PRIOR ART DOCUMENT]] [[PATENT DOCUMENT]]

[0003] [[Patent Document 1]] Japanese Patent Laid-Open No. 2022-066375 [[SUMMARY OF THE INVENTION]] [[Problem to be Solved by the Invention]]

[0004] When putting on a conventional pants-type paper diaper as described in Patent Document 1, one leg is inserted into the waist opening and then into one leg opening (also referred to as a leg hole), and then the other leg is inserted into the waist opening and into the other leg opening. However, in a pants-type paper diaper, the size of the opening for inserting legs is narrow, and insertion is performed one leg at a time, so the wearer may lose balance during putting on. For example, when a wearer whose physical function has started to decline puts on a pants-type paper diaper, there is a risk that the toe may get caught on the leg opening, three-dimensional gathers, the absorbent body or the like, causing the wearer to fall.

[0005] Furthermore, there has been a problem that if the waist-side end portion is not pulled up sufficiently when putting on the diaper, the absorbent body will not be in close contact with the wearer's body (urination area), which causes urine leakage.

[0006] Therefore, this disclosure aims to provide a disposable diaper that is easy for one person to put on and can be easily fitted to the body. [Means for solving the problem]

[0007] To solve the above problems, a disposable diaper according to a first aspect of the present invention comprises an outer body having a front waist region located on the wearer's abdominal side when worn, a rear waist region located on the wearer's back side, and a crotch region located between the wearer's legs; an absorbent body disposed in at least the crotch region of the outer body; and a means for attaching and detaching the outer body, which allows the front waist region and the crotch region including the absorbent body to be separated from each other and attached to each other.

[0008] A second aspect of the present invention is a disposable diaper according to the first aspect, wherein the front waist region and the rear waist region of the outer body are formed in a cylindrical shape extending vertically and have a waist opening at the top, the front waist region and the rear waist region are provided with an expandable member that can expand and contract the waist opening in the circumferential direction, and the crotch region of the outer body extends continuously from the rear waist region.

[0009] A third aspect of the present invention is a disposable diaper according to the first or second aspect, wherein the fastening means is a hook tape provided in the crotch area of ​​the outer body.

[0010] A fourth aspect of the present invention is a disposable diaper according to the first or second aspect, wherein a plurality of markings are provided on the front waist area of ​​the outer body at positions spaced apart vertically from each other, to serve as a guide when attaching the crotch area. [Effects of the Invention]

[0011] According to this disclosure, disposable diapers can be easily put on by one person and can be easily fitted to the body. [Brief explanation of the drawing]

Figure 1 is a front view perspective of the disposable diaper according to one embodiment of the present invention when it is being worn. Figure 2 is a front view perspective of the disposable diaper of Figure 1 before it is being worn.

[0014] Furthermore, the figures do not specify the relative sizes of the components of the disposable diaper 10. The dimensions of each component can be appropriately selected from a wide range depending on the intended use of the disposable diaper 10, the age of the wearer, etc.

[0015] In this specification, wearing the diaper 10 means the state in which the diaper 10 is attached to the body, regardless of whether it is before, during, or after the absorption of bodily fluids. Furthermore, "front side" means the direction that is the wearer's abdomen when the diaper 10 is worn, and "back side" means the direction that is the wearer's back. Furthermore, "upper side" means the direction that is the wearer's head when the diaper 10 is worn, and "lower side" means the direction that is the wearer's feet. Furthermore, the left and right directions mean the left and right directions as viewed from the wearer when facing forward. Furthermore, the longitudinal direction of each component of the diaper 10 means the longitudinal direction when the diaper 10 is unfolded (as shown in Figure 2), and is the direction along arrow X in Figure 2. Furthermore, the width direction of each component of the diaper 10 means the direction perpendicular to the longitudinal direction when the diaper 10 is unfolded (the direction along left and right), and is the direction along arrow Y in Figure 2. Furthermore, the thickness direction of each component of the disposable diaper 10 refers to the direction in which each component is stacked. Also, the skin side of each component of the disposable diaper 10 refers to the direction of the thickness direction that is on the skin side of the wearer when the disposable diaper 10 is worn, and the non-skin side refers to the direction of the thickness direction that is opposite to the skin side. Furthermore, body fluids refer to liquids that are expelled from the body to the outside, such as urine, blood, and water in loose stools.

[0016] (Disposable diapers) As shown in Figures 1 and 2, the disposable diaper 10 according to this embodiment comprises an outer body 20 that forms a pant-like outer shape when worn, an absorbent body 40 supported by the outer body 20, and a hook tape (attachment means) 50 that allows the crotch area of ​​the outer body 20, which will be described later, to be attached to the front waist area.

[0017] (Exterior) As shown in Figures 1 and 2, the outer casing 20 is a component that constitutes the external shape of the disposable diaper 10, and is formed by laminating nonwoven fabric and an elastic material. In this embodiment, the outer casing 20 is formed by laminating an outer nonwoven fabric sheet 21a on the non-skin side, an inner nonwoven fabric sheet 21b located on the skin side of the outer nonwoven fabric sheet 21a, and a plurality of elastic materials 22, 30 interposed between the outer nonwoven fabric sheet 21a and the inner nonwoven fabric sheet 21b. In addition to the outer nonwoven fabric sheet 21a and the inner nonwoven fabric sheet 21b, an auxiliary sheet that covers the periphery of the absorbent body 40, which will be described later, may be provided on the outer casing 20, and the auxiliary sheet may be laminated on the inner nonwoven fabric sheet 21b.

[0018] The outer nonwoven fabric sheet 21a and the inner nonwoven fabric sheet 21b can be made of nonwoven fabrics such as thermal bond nonwoven fabric, air-through nonwoven fabric, or spunbond nonwoven fabric, preferably air-through nonwoven fabric or spunbond nonwoven fabric, and made of thermoplastic resins such as polypropylene, polyester, or polyethylene.

[0019] The outer casing 20 has a front waist area 23 located on the wearer's ventral side (front of the abdomen) when worn, a rear waist area 24 located on the wearer's dorsal side (rear of the back), and a crotch area 25 located between the wearer's legs. The front waist area 23 and the rear waist area 24 are areas with side seal portions 26 on both sides in the width direction (areas that do not form the leg openings 27a and 27b described later), while the crotch area 25 is an area that does not have side seal portions 26 (areas that form the leg openings 27a and 27b).

[0020] As shown in FIG. 2, both widthwise ends of the front waist circumference region 23 and both widthwise ends of the rear waist circumference region 24 are joined to each other to constitute left and right side seal portions 26. As a result, the front waist circumference region 23 and the rear waist circumference region 24 are formed in a vertically extending cylindrical shape. The cylindrically formed front waist circumference region 23 and rear waist circumference region 24 have, at the upper end thereof, a waist opening 28 that opens upward. The crotch region 25 extends continuously from the lower end of the rear waist circumference region 24. In the longitudinal direction of the crotch region 25, a distal end 25a side opposite to the rear waist circumference region 24 is detachably attachable to a surface (non-skin side surface) of the front waist circumference region 23 by a hook tape 50. Accordingly, the outer cover 20 can be placed in a detached state in which the crotch region 25 is separated from the front waist circumference region 23 (the state shown in FIG. 2) and an attached state in which the crotch region 25 is attached to the front waist circumference region 23 (the state shown in FIG. 1).

[0021] As shown in FIG. 1, the outer cover 20 in the attached state is formed into a pants shape as a whole, and includes a waist opening 28 at an upper portion of the front waist circumference region 23 and the rear waist circumference region 24, and leg openings 27a and 27b on both left and right sides of the crotch region 25. The waist opening 28 is a portion into which the waist of a wearer is inserted when worn, and is defined by upper end edges of both the front waist circumference region 23 and the rear waist circumference region 24. A peripheral edge portion of the waist opening 28 in the front waist circumference region 23 and the rear waist circumference region 24 has elasticity in the circumferential direction. The left and right leg openings 27a and 27b are portions into which the legs of the wearer are inserted, and are defined at both left and right end edges of the crotch region 25 when placed in the attached state. A peripheral edge portion of the left and right leg openings 27a and 27b of the crotch region 25 has elasticity in the circumferential direction.

[0022] As shown in Figures 1 and 2, the front waist circumference region 23 and the rear waist circumference region 24 are provided with a plurality of elastic members 22 that can expand and contract in the circumferential direction of the waist opening 28. The plurality of elastic members 22 are provided at positions spaced apart from each other vertically. Each elastic member 22 is bonded to the exterior nonwoven fabric sheet 21a and the interior nonwoven fabric sheet 21b of the front waist circumference region 23 and the rear waist circumference region 24. As the elastic member 22, for example, filamentous, string-shaped, or flat-shaped members made of natural rubber, synthetic rubber, polyurethane, or the like can be appropriately used.

[0023] In the front waist circumference region 23, a plurality of marks 29 (in the present embodiment, four marks 29a to 29d) serving as a guide when attaching the crotch region 25 are provided so as to be visible from the outside (surface side). The plurality of marks 29 may be, for example, lines extending in the width direction colored and drawn on the surface of the front waist circumference region 23. The plurality of marks 29 are provided at positions spaced apart from each other vertically. The four marks 29a to 29d of the present embodiment serve as a guide for the position where the tip end 25a of the crotch region 25 is arranged when attaching the crotch region 25. The plurality of marks 29 are not limited to lines extending in the width direction, and any mark 29 that serves as a guide when attaching the crotch region 25 may be used. For example, the plurality of marks 29 may be a plurality of regions extending in the width direction and arranged side by side in the vertical direction with different colors from each other, or may be a plurality of patterns (dots, designs, etc.) provided vertically at equal intervals or different intervals.

[0024] The crotch region 25 continuously extends from the lower end of the rear waist circumference region 24. In the crotch region 25 of the present embodiment, both longitudinal sides (the front waist circumference region 23 side and the rear waist circumference region 24 side) are formed to be wide, and the intermediate portion in the longitudinal direction is formed to be narrow. Both side edges in the width direction of the crotch region 25 define the left and right leg openings 27a, 27b.

[0025] Multiple stretchable members 30 are provided on the outer edges of both sides in the width direction of the crotch area 25, and are expandable and contractible in the circumferential direction of the left and right leg openings 27a and 27b. The multiple stretchable members 30 are provided at positions spaced apart from each other in the width direction. Each stretchable member 30 is joined to the outer nonwoven fabric sheet 21a and the inner nonwoven fabric sheet 21b of the crotch area 25. As the stretchable members 30, thread-like, string-like, or flat-shaped materials such as natural rubber, synthetic rubber, or polyurethane can be used as appropriate.

[0026] The leading edge 25a of the crotch area 25 is formed to extend further longitudinally and wider than the left and right leg openings 27a and 27b so that it overlaps with the surface of the front waist area 23 when worn. That is, the leading edge 25a of the crotch area 25 is provided with an extension 31 that extends longitudinally beyond the area that demarcates the left and right leg openings 27a and 27b so that it overlaps with the surface of the front waist area 23 when worn. A hook tape 50 is provided on the skin-facing surface of the extension 31 of the crotch area 25 to allow the crotch area 25 to be attached to and detached from the front waist area 23. The hook tape 50 is an attachment / detachment means that functions as the hook material of a hook-and-loop fastener, and in this embodiment, it is attached to and detached from the surface of the front waist area 23. The hook tape 50 in this embodiment extends across the width direction of the extension 31 that allows the crotch area 25 to be attached to and detached from the front waist area 23. In other words, the hook tape 50 functions as a means of attachment and detachment that allows the crotch area 25 and the front waist area 23 to be separated and detached from each other, and to be attached to each other. When the hook tape 50 is provided in the crotch area 25, a loop tape (a means of attachment and detachment that functions as the loop material of a hook-and-loop fastener) corresponding to the hook tape 50 may be provided on the surface of the front waist area 23. Furthermore, the means of attachment and detachment is not limited to the hook tape 50. For example, an adhesive tape (means of attachment and detachment) may be provided on the extension 31 of the crotch area 25, and this adhesive tape may function as a means of attachment and detachment.

[0027] The longitudinal length (X direction) L1 of the extension 31 of the crotch region 25 is formed to be shorter than the longitudinal length L2 of the front waist region 23. That is, when the outer lower end of the extension 31 in the width direction (the ends on the left and right leg openings 27a, 27b sides) is aligned with the lower ends of the left and right side seal portions 26 of the front waist region 23 (as shown in Figure 1), the surface of the front waist region 23 is exposed above the tip 25a (upper edge) of the crotch region 25, and at least one mark 29 (three marks 29b to 29d in Figure 1) is exposed on the surface of the exposed front waist region 23. This allows the tip 25a of the crotch region 25 to be further raised and attached, so the degree of contact of the crotch region 25 with the body can be appropriately adjusted.

[0028] (Absorbent body) The absorbent body 40 is a component for absorbing and retaining bodily fluids, and is mainly positioned on the inner surface of the crotch area 25 of the outer body 20 and is joined to the outer body 20. The absorbent body 40 has a roughly band-like shape in the front-to-back direction, covering the wearer's crotch area from the front, below, and behind. The rear end of the absorbent body 40 may extend to the rear waist area 24 of the outer body 20.

[0029] The absorbent body 40 includes a liquid-permeable top sheet 41 on the skin side, a liquid-impermeable back sheet 42 on the non-skin side, and an absorbent material 43 placed between the top sheet 41 and the back sheet 42.

[0030] The top sheet 41 is formed from a substrate that has liquid permeability, allowing bodily fluids to move to the absorbent material 43. Examples of substrates include nonwoven fabrics such as thermal bond nonwoven fabric, composite nonwoven fabrics formed by laminating thermal bond nonwoven fabric / spunbond nonwoven fabric, open films such as open polyethylene film, foamed films such as polyethylene foam and urethane foam, or composite sheets formed by laminating these. The top sheet 41 may also be embossed or perforated on its surface to improve liquid permeability. Known methods can be used without limitation for these embossing and perforating processes. Furthermore, to reduce skin irritation, the top sheet 41 may contain lotions, antioxidants, anti-inflammatory components, pH adjusters, antibacterial agents, moisturizers, etc.

[0031] The shape of the top sheet 41 is not particularly restricted, but it should be shaped to cover the absorbent 43 in order to guide bodily fluids to the absorbent 43 without leakage.

[0032] The backsheet 42 can be formed using a liquid-impermeable substrate so as to prevent leakage of bodily fluids held by the absorbent 43 to the non-skin side, and can be formed from materials such as a resin film or a composite sheet formed by laminating a resin film and a nonwoven fabric. The nonwoven fabric used in the composite sheet is not particularly limited in its manufacturing method and can include, for example, a composite nonwoven fabric formed by laminating multiple identical and / or different nonwoven fabrics such as spunbond nonwoven fabric, meltblown nonwoven fabric, spunbond nonwoven fabric / meltblown nonwoven fabric, spunbond nonwoven fabric / meltblown nonwoven fabric / spunbond nonwoven fabric, and composite materials thereof. Examples of resin films include polyester, polyvinyl alcohol, polyethylene, polypropylene, and composite films of polyethylene and polypropylene.

[0033] The back sheet 42 is preferably made breathable to prevent stuffiness during wear. To make the back sheet 42 breathable, for example, a filler can be compounded into the base resin film, or the back sheet 42 can be embossed. Calcium carbonate can be used as a filler, and the compounding method can be any known method without limitation. For example, a porous (breathable) resin film can be obtained by kneading a resin and a filler, forming the resulting mixture into a film, and then removing the filler from the resulting film.

[0034] The absorbent body 43 includes a body fluid absorbent material, preferably a base material and a body fluid absorbent material held by the base material. The body fluid absorbent material is not particularly limited as long as it absorbs and retains body fluids, but examples include fluff pulp and super absorbent polymer (SAP). The base material of the absorbent body 43 is not particularly limited as long as it is generally used in absorbent articles such as sanitary napkins, diapers, and incontinence pads, and is formed from materials such as fluff pulp, cotton, rayon, acetate, tissue, absorbent paper, and hydrophilic nonwoven fabric. Among these, fluff pulp is preferred from the viewpoint of absorbency. Examples of fluff pulp include wood pulp, synthetic fibers, polymer fibers, and non-wood pulp that have been defibrated into a cotton-like form.

[0035] SAP is not particularly limited as long as it can absorb body fluids and prevent backflow. Examples include those formed from materials such as polyacrylates, polyaspartates, (starch-acrylic acid) graft copolymers, (acrylic acid-vinyl alcohol) copolymers, (isobutylene-maleic anhydride) copolymers, and their saponified products. Among these, polyacrylates are preferred from the viewpoint of absorption per unit weight, and sodium polyacrylates are more preferred.

[0036] The absorbent body 43 preferably contains a base material and SAP, and its composition includes a material formed by mixing SAP particles into the base material, or an SAP sheet in which SAP particles are fixed between base materials. Furthermore, from the viewpoint of preventing the SAP particles from falling off and stabilizing the shape of the absorbent body 43, it is preferable to wrap the absorbent body 43 in a carrier sheet. Alternatively, the SAP may be formed into fibers and mixed with the base material. The base material of the carrier sheet may be any material that is hydrophilic, such as tissue, absorbent paper, or hydrophilic nonwoven fabrics such as airlaid nonwoven fabric. If the absorbent body 43 comprises multiple carrier sheets, the base materials of the carrier sheets may be the same or different.

[0037] The shape of the absorbent 43 is not particularly limited and can be rectangular, hourglass-shaped, I-shaped, a rounded rectangle, an oval, or an elongated ellipse. The absorbent 43 may be used in two or more layers.

[0038] The absorbent body 40 may include a pair of three-dimensional gathers (not shown) to prevent lateral leakage of bodily fluids. The three-dimensional gathers may have their outer ends in the width direction (along the direction of arrow Y in Figure 2) fixed to the skin-facing surface of the back sheet 42, their middle portions in the width direction fixed to the skin-facing surface of the top sheet 41, and their inner ends in the width direction being free ends that extend to the skin-facing surface of the top sheet 41. By configuring the three-dimensional gathers in this way, the area near the free ends of the three-dimensional gathers is given uprightness, allowing them to deform to conform to the wearer's body shape.

[0039] Next, we will explain how to put on the disposable diaper 10. When putting on the disposable diaper 10, first, the crotch area 25 of the disposable diaper 10 should be separated from the front waist area 23 and put into a detached state.

[0040] When putting on the disposable diaper 10, the user first inserts one leg from above into the waist opening 28 of the disposable diaper 10, passing it through the inner diameter of the tubular front waist area 23 and rear waist area 24. Next, the user inserts the other leg from above into the waist opening 28 of the disposable diaper 10, passing it through the inner diameter of the tubular front waist area 23 and rear waist area 24. After both legs have been inserted through the inner diameter of the tubular front waist area 23 and rear waist area 24, the user pulls the front waist area 23 and rear waist area 24 up to the correct waist position. Finally, the user pulls the front end 25a of the crotch area 25 upward and forward from between their legs, and attaches the hook tape 50 of the extension 31 of the crotch area 25 to the surface of the front waist area 23, thereby putting the disposable diaper 10 into place. This allows the user to put on and wear the disposable diaper 10.

[0041] In the disposable diaper 10 configured as described above, the crotch area 25 of the disposable diaper 10 can be separated from the front waist area 23 and made detachable. In the detachable state, the left and right leg openings 27a and 27b are not partitioned, and the absorbent body 40 hangs down continuously from the rear waist area 24. Therefore, by putting the disposable diaper 10 into the detachable state, the left and right leg openings 27a and 27b, which are prone to catching on the user's toes when putting it on, can be left open, and the three-dimensional gathers of the absorbent body 40 can be easily moved to the rear. This prevents the user's toes from getting caught on the left and right leg openings 27a and 27b or the three-dimensional gathers of the absorbent body 40 when putting it on.

[0042] Furthermore, the hook tape (attachment means) 50 allows the crotch area 25 and the front waist area 23 to be attached to each other. As a result, the user inserts both legs into the inner diameter of the tubular front waist area 23 and rear waist area 24, pulls the diaper 10 up to the normal waist position, and then pulls the crotch area 25 forward from between the legs and attaches it to the front waist area 23, thereby inserting both legs into the left and right leg openings 27a and 27b. This allows the user to easily put on the diaper 10 by themselves, unlike when inserting one leg at a time into the narrow left and right leg openings 27a and 27b.

[0043] Furthermore, when the crotch area 25 is pulled forward from between the legs and attached to the front waist area 23, the user can easily adjust the degree to which the crotch area 25 adheres to the body by the amount it is pulled up. The user can then adjust the attachment position of the crotch area 25 to the front waist area 23 when putting on the disposable diaper 10. As a result, even users of different sizes can easily ensure that the crotch area 25 adheres tightly to the body when putting on the disposable diaper 10. This helps to reduce urine leakage.

[0044] Thus, according to this embodiment, the disposable diaper 10 can be easily put on by one person and can be easily fitted to the body. As a result, even wearers whose physical functions have begun to decline can put on the disposable diaper 10 by themselves and have it easily fitted to their body, thus preventing falls during application due to the toes getting caught on the left and right leg openings 27a, 27b or the absorbent body 40.

[0045] Furthermore, when the user puts on the disposable diaper 10, they can adjust the attachment position of the crotch area 25 relative to the front waist area 23, thereby adjusting the degree of contact of the multiple elastic members 30 (leg gathers) provided in the left and right leg openings 27a and 27b.

[0046] Furthermore, since the front waist area 23 and the rear waist area 24 are formed in a cylindrical shape, and multiple stretchable members 22 that can expand and contract in the circumferential direction of the waist opening 28 are provided, the disposable diaper 10 can be fitted to the wearer's waist.

[0047] Furthermore, since the front waist area 23 and the rear waist area 24 are formed in a cylindrical shape, and multiple stretchable members 22 that can expand and contract in the circumferential direction of the waist opening 28 are provided, the disposable diaper 10 will not fall down even if you release both hands after raising the front waist area 23 and the rear waist area 24 to the waist when putting on the disposable diaper 10. As a result, the task of pulling up the crotch area 25 from between the legs forward can be done with both hands, making it easy to put on the disposable diaper 10 by one person, and the degree of contact of the crotch area 25 with the body can be easily adjusted.

[0048] Furthermore, since the hook tape 50 is the means for attaching and detaching the crotch area 25 and the front waist area 23 to each other, it can be an inexpensive and simple means of attachment and detachment.

[0049] Furthermore, the front waist area 23 is provided with multiple markers 29 positioned vertically and spaced apart from each other, serving as a guide when attaching the crotch area 25. Therefore, after the wearer adjusts the degree of contact of the diaper 10 to the body once, they can remember the markers 29, and the next time they put it on, they can easily put on the diaper 10 with the appropriate degree of contact based on the markers 29. In addition, not only the wearer, but also caregivers, for example, can recognize the markers 29 that are appropriate for the person being cared for (the wearer), and can easily put on the diaper 10 with the appropriate degree of contact.

[0050] Furthermore, since the crotch area 25 and the front waist area 23 are detachable from each other, a caregiver, for example, can easily visually check the absorption capacity of the absorbent body 40 by removing the crotch area 25 from the front waist area 23. In this way, the absorbent body 40 can be checked by removing the crotch area 25 from the front waist area 23, which is different from the case where a finger is inserted into the gap between the waist opening 28 and the left and right leg openings 27a and 27b to widen the waist opening 28 and the left and right leg openings 27a and 27b to check the absorbent body 40. This makes it easy and hygienic to determine when to change the disposable diaper 10.

[0051] Although the present invention has been described above based on the above embodiments, the present invention is not limited to the contents of the above embodiments, and can naturally be modified as appropriate without departing from the present invention. In other words, all other embodiments, examples, and operational techniques made by those skilled in the art based on these embodiments are of course included in the scope of the present invention.
