JP5091088B2 - Urine pad - Google Patents

Description

  The present invention, like a disposable diaper, comprises an absorbent body, a topsheet at least partly made of a liquid-permeable material, and arranged to cover the surface of the absorbent body, and a liquid-impermeable material. The present invention relates to a urine pad which is an absorbent article including a back sheet disposed so as to cover the back surface of the body.

  In recent years, a disposable diaper and a urine pad (also referred to as “inner pad”, “auxiliary pad”, etc.) have been used in combination in order to reduce labor when changing the diaper. For example, the disposable diaper is not directly applied to the wearer's skin, but a urine pad is laminated on the top sheet side surface of the disposable diaper, and the disposable diaper on which the urine pad is laminated is applied to the wearer's skin. . By doing so, even when the wearer excretes, it is sufficient to replace only the urine pad, and the disposable diaper can be used as it is. Therefore, compared with the method of exchanging the whole disposable diaper for every excretion like before, exchange is easy and the caregiver's care effort is reduced. Moreover, since a urine pad is cheaper than a disposable diaper, it is advantageous in terms of cost as compared with a method of exchanging the entire disposable diaper every time it is excreted.

  As such a urine pad, for example, a urine collection pad provided with a latching means (such as a mechanical fastener) for fixing the urine collection pad to a disposable diaper is disclosed (see Patent Documents 1 and 2). .

  Since the urine absorbing pad described in Patent Document 1 or 2 includes a mechanical fastener or the like, there is an advantage that it can be reliably fixed to a disposable diaper. The urine removing pad is easy to replace as compared with a method of exchanging the entire disposable diaper every time it is excreted.

  However, the work of drawing out and replacing the urine collecting pad between the disposable diaper and the wearer's skin still requires time and labor. In particular, it is difficult to replace the urine pad for people who are paralyzed or have joint contractures (the joints are stiff and difficult to bend and stretch), or who cannot sleep on their back and can only take a lateral position. There was a problem that there was. That is, a person with paralysis or joint contracture often has a narrow range of motion of the hip joint and cannot open the crotch widely. In addition, even a person who can only take a lateral posture is difficult to open the crotch from the posture. In these cases, it is difficult to insert the conventional urine pad through a narrow crotch gap, and it is difficult to arrange the urine pad so as to be in close contact with the wearer's skin. That is, it cannot be said that it can be exchanged quickly and easily, and still leaves room for improvement.

  The present invention has been made in view of the above-described problems of the prior art, is easy to wear, can be exchanged quickly and easily, and people with paralysis or joint contracture, or lying on their back The present invention provides a urine pad that can be suitably used even for a person who cannot open the crotch widely, such as a person who cannot take a posture in a lateral position.

  As a result of intensive investigations to solve the problems of the prior art as described above, the present inventor connected the unused pads to the used pads and then withdraws the used pads. It was found that unused pads can be attached at the same time, and that quick and simple replacement can be achieved. Then, it is conceived that the above problem can be solved by providing a fastening material for connection with another pad and arranging the fastening material only in either the left or right region of the pad. Completed the invention. Specifically, the following urine pads are provided by the present invention.

[8] The urine pad according to any one of [1] to [7], further including a fixing material capable of fixing the fixing material.

  The urine pad of the present invention is easy to wear and can be exchanged quickly and easily. Therefore, it can be suitably used for people who are paralyzed or joint contracture, or who cannot sleep on their back and can only take a lateral position, such as those who cannot open the crotch.

  Hereinafter, the best mode for carrying out the urine pad of the present invention will be specifically described. However, the present invention broadly encompasses urine pads having the invention-specific matters, and is not limited to the following embodiments.

[1]: Features of the urine pad of the present invention:
Urine pad of the present invention, as the urine pad 1A shown in FIG 1A~ Figure 1C, can have stop for other urine pad, further comprising a fastening member 54A to allow connection of the urine pad between The fastening material 54A is a urine pad arranged in either the left or right region 56 obtained by dividing the urine pad 1A by the center line Lc in the width direction.

  The urine pad 1A can connect the used pad and the unused pad using the fastening material 54A. As a result, it is possible to pull out the used pad to be replaced and attach the unused pad at the same time. Therefore, the urine pad can be used quickly and easily even when the wearer is a person who cannot open the crotch because of paralysis, joint contracture, or the like, or because the posture can only be in the lateral position. Can be exchanged.

  Also, the fastening material 54A is disposed in either the left or right region 56 where the urine pad 1A is divided by the center line Lc in the width direction. That is, in the urine pad 1A, the fastening material 54A is attached only to one region 56, and the fastening material is not attached to the other region 58. Therefore, compared with the case where the fastening material 54A is attached to the entire region 56, 58, it is easy to connect the used pad and the unused pad.

  More specifically, the urine pad 1A can be inserted in advance in a direction in which the fastening material 54A and its fastening site are easily visible. In the example shown in FIG. 1E, the urine pad 1A is arranged so that the region 56 is located on the back side of the drawing and the region 58 is located on the front side of the drawing. Therefore, it is easy to visually recognize the fastening material 54A from the front side of the drawing, and the fastening can be reliably performed while visually confirming the fastening material 54A. Such a configuration is effective when the wearer is a person who can only take a lateral position. This can be easily understood by assuming that the rear side of the drawing in FIG. 1E is the lower leg side of the lateral position and the front side of the drawing is the upper leg side of the lateral position.

  Further, even when the fastening material 54A is a hook material, an adhesive portion or a self-adhesive film, the unused pad can be inserted without the fastening material 54A being caught by the used pad. That is, if the unused pad is inserted in a state where the region 56 provided with the fastening material 54A is floated from the used pad, the fastening material 54A is not caught on the used pad. At this time, when the region 58 where the unused pad fastening material 54A is not attached is brought into contact with the used pad, the used pad becomes a guide, and the unused pad can be inserted more stably.

  On the other hand, when the fastening material 54A is attached to both the regions 56 and 58, the unused pad cannot be inserted as described above, and the fastening material 54A is easily caught on the used pad. Therefore, the connection between the used pad and the unused pad may not be successful.

[1-1] Fastening material:
As shown in FIG. 1B, the urine pad of the present invention includes a fastening material 54 </ b> A that can be fastened to other urine pads and enables the urine pads to be connected to each other.

  The fastening type of the "fastening material" is as follows: Fastening using the adhesive strength of the adhesive (adhesive fastener); Fastening using the mechanical connection of the convex and concave parts (hook material and loop material) ( Mechanical fasteners); Fastening using self-adhesion between films (self-adhesive film); Fastening using string fastening; Fastening using button fastening; Among them, it is preferable to use a mechanical fastener that can be easily attached to another urine pad and has a high fastening force and does not decrease even after multiple times of detachment. The urine pad 1A shown in FIG. 1B is an example in the case where a hook material is attached as the fastening material 54A.

  Specific members corresponding to the “fastening material” include an adhesive part, a hook material, a self-adhesive film, a string, a button, and the like. What is necessary is just to attach these members to the predetermined site | part of a urine pad. The adhesive part can be attached by applying an adhesive, and the hook material can be attached by bonding with an adhesive such as a hot melt adhesive.

  The “self-adhesive film” means a resin film that itself has adhesiveness and adhesiveness even without applying an adhesive. For example, a polypropylene-natural rubber bilayer film (trade name “Besar” / manufactured by Kitamura Seisakusho), a polyester elastomer film (trade name “Mating Surface / Fastener” / manufactured by Sumitomo 3M Ltd.), and the like can be mentioned.

  In the urine pad of the present invention, as shown in FIG. 1B, the fastening material 54A is disposed in either the left or right region 56 where the urine pad 1A is divided by the center line Lc in the width direction. “One of the left and right regions” is the region 56 or the region 58 in the case of the urine pad 1A shown in FIG. 1B. That is, contrary to the urine pad 1A shown in FIG. 1B, the same effect can be obtained by attaching the fastening material 54A only to the right region 58 in the drawing.

  The “width direction” means a direction orthogonal to the front-rear direction of the urine pad, that is, the left-right direction. The urine pad is often configured to have a shape that is long in the front-rear direction and short in the left-right direction, such as a substantially rectangular shape. Therefore, the short direction is usually the “width direction”. The “width-direction center line” is a straight line passing through the center in the width direction of the urine pad 1A in the front-rear direction of the urine pad 1A, as shown in FIGS. 1A and 1B. In other words, it can also be referred to as a straight line connecting the midpoint of the front end E1 and the midpoint of the rear end E2 of the urine pad 1A.

  As one form of the urine pad of the present invention, like the urine pad 1A shown in FIG. 1, the fastening material 54A is at least one kind of fastening selected from the group of a hook material, an adhesive portion and a self-adhesive film. The fastening material 54A is disposed at the front end portion or the rear end portion of the urine pad 1A and is directly joined to the surface on the top sheet 18 side or the surface on the back sheet 20 side of the urine pad 1A. Is preferred.

  The fastening material can be configured in a planar manner, and in addition to not giving the wearer a feeling of foreign matter, it can be easily attached to the urine pad using a hot melt adhesive or the like, This is preferable in that the fastening operation is easier. In addition, since the fastening material is arranged at the front end portion or the rear end portion of the urine pad, it is possible to fix the unused pad to the used pad without connecting the unused pad and to connect the two urine pads. .

  Especially, it is preferable that the front end or the rear end of the fastening material is arranged so as to coincide with the front end or the rear end of the urine pad. By making the front end or the rear end of the fastening material coincide with the front end or the rear end of the urine pad, the fastening material can be easily seen and alignment at the time of connection is facilitated.

  In the present specification, the “front end” means a portion having a length of 20% on the front end E1 side of the total length of the pad, and the “rear end” means a portion having a length of 20% on the rear end E2 side of the total length of the pad. Means part. When the urine pad has a target shape, it is not necessary to distinguish between the “front end” and the “rear end”.

  The “surface on the top sheet side” means the surface of the urine pad that contacts the skin of the wearer, and not only the surface of the top sheet but also other members arranged on the skin side of the wearer (for example, three-dimensional gathers) Etc.). Similarly, the “surface on the back sheet side” means a surface that contacts the wearer's clothes, and is not only the surface of the back sheet but also other members disposed on the wearer's clothes side (for example, a cover sheet). Etc.).

  “Directly joined” means that the fastening material itself is joined to the surface of the top sheet side of the urine pad, and there is no member interposed between the fastening material and the urine pad. . That is, it shows that the fastening material is different from the form attached to the urine pad via a member such as a tape-like base material as in the case of using the fastening tape described later.

  When arrange | positioning a fastening material in a front-end part or a rear-end part, you may arrange | position a fastening material continuously or intermittently (intermittently) along a front end or a rear end. For example, in the urine pad 1A shown in FIG. 1B, the fastening material 54A is disposed at the front end portion of the urine pad 1A, and is continuously attached along the front end E1 of the urine pad 1A.

  However, the urine pad of the present invention includes two fastening materials 54B as in the urine pad 1B shown in FIG. 2B, and the fastening materials 54B are arranged one by one at both side edges in one region 56. It is preferable. Compared with the form in which the fastening material 54A is continuously provided along the front end E1 such as the urine pad 1A shown in FIG. 1B, this form is obtained by pulling out the used pad and then peeling off the fastening material 54B. It is preferable in terms of easy. In the present specification, “both side edge portions” mean portions on both sides excluding the 60% width portion at the center in the width direction in the entire width of the region.

[1-2] Fastening tape:
Urine pad of the present invention, as the urine pad 1B shown in FIG. 2B, the fastening member 62A is at least one selected from the group of the hook material, the adhesive portion and the self-adhesive film, the fastening member 62A a fastening tape 64A by the tape-shaped substrate 60A is configured, fastening tape 64A, together with the fastening member 62A is attached to the distal end portion of the tape-shaped substrate 60A, the distal end of the tape-shaped substrate 60A is It is preferable that the urine pad 1B is fixed to the surface on the back sheet 20 side.

  The form in which the fastening material 62A is attached to the tape-shaped substrate 60A is not in the form in which the fastening material 54A such as the urine pad 1A shown in FIG. 1B is directly joined to the urine pad 1A. Since the connection is possible without overlapping the used pads, the connection portion is not bulky and is preferable in that it can easily pass through a narrow crotch.

  The material of the tape-shaped substrate is not particularly limited, but a nonwoven fabric, a plastic film, or the like can be used. FIG. 2C is an enlarged side view schematically showing the fastening tape 64A shown in FIG. 2B as viewed from the side. This fastening tape 64A is an example in which a tape-like base material 60A made of a plastic film and an adhesive portion as a fastening material 62A are formed at the tip of the tape-like base material 60A. In this example, the tape-shaped substrate 60A is stored in a folded state so as to have a Z-shaped cross section (FIG. A). At the time of use, the fastening material 62A (adhesive part) is peeled off from the tape-shaped substrate 60A (FIG. B), and the fastening tape 64A is extended (FIG. C).

  In the urine pad of the present invention, as in the urine pad 1C shown in FIG. 3B, the tape-like base material 60B is preferably made of an elastic material and is extensible in the length direction. By configuring the tape-shaped substrate 60B with a stretchable material, the length of the tape-shaped substrate can be shortened compared to the case where the tape-shaped substrate is configured with a non-stretchable material such as a plastic film. The effect that can be obtained.

  As the stretchable material, an elastic nonwoven fabric, an elastomer spunbond nonwoven fabric, or the like can be used. More specifically, Straflex (produced by Idemitsu Unitech Co., Ltd.), Espancione (produced by KB Seiren Co., Ltd.) and the like can be suitably used under the trade names below.

  The form of the fastening tape is not particularly limited. For example, it is possible to divert the configuration of a tape-type disposable diaper fastening tape or a disposal tape for fixing and discarding a used urine pad in a rolled state. As the fastening material, the above-described adhesive portion or hook material can be suitably used.

  The fastening tape is preferably arranged so that its free end coincides with the tip of the urine pad. The fastening tape can be easily removed by making its free end coincide with the tip of the urine pad.

  The urine pad of the present invention has only the fastening material 62B attached to the fastening tape 64B as a fastening material for connecting to another urine pad, like the urine pad 1C shown in FIG. 3B. May be. However, like the urine pad 1B shown in FIG. 2B, one having both the fastening material 54B directly joined to the urine pad 1B and the fastening material 62A attached to the fastening tape 64A is preferable.

  In the urine pad 1B shown in FIG. 2B, the fastening by the fastening material 54B is reinforced by the fastening material 62A of the fastening tape 64A, and the urine pads are more firmly connected. Therefore, when pulling out the used urine pad, it is possible to effectively prevent the situation where the connection with the unused urine pad is disconnected and the quick replacement is hindered.

[1-3] Bonding material:
The urine pad of the present invention preferably further includes a to-be-fixed material 68 capable of fixing the fixing material 62B as in the urine pad 1C shown in FIG. 3B. By causing fastened the fastening member 62B to be fastening member 68, the fastening member 62B as compared with the case where is fastened directly to the urine pad 1C, it is possible to more firmly bond the used pad It is possible to effectively prevent a problem that the urine pads are disconnected when they are pulled out.

  “Fastening material” includes a plastic film with a smooth surface when the fastening material is an adhesive part, a loop material when it is a hook material, a self-adhesive film when it is a self-adhesive film, and a button In the case of loop string, a string or the like can be used.

  In the urine pad of the present invention, as in the urine pad 1C shown in FIG. 3B, the fixing material 68 is an end portion of the region 56 where the fixing material 62B is provided, on the side where the fixing material 62B is not disposed. It is preferable to arrange in. Further, when both the fastening tape 64B and the fastening material 68 are attached to the surface on the back sheet 20 side as in the urine pad 1C shown in FIG. 3B, both the fastening tape 64B and the fastening material 68 are visually recognized. However, since the used pad and the unused pad can be connected, it contributes to a quick and simple exchange of the urine pad.

[1-4] Vulnerable part:
Urine pad of the present invention, along the width direction center line of the urine pad, weakened portion to facilitate folding into a mountain fold shape or valley fold shape that is formed. Such a structure makes it easy to fold the urine pad during replacement, and therefore people who cannot open the crotch widely for reasons such as paralysis or joint contracture, or because they can only take a lateral position. The urine pad can be easily inserted between the crotch of the chin and can be replaced quickly and easily.

  The “fragile portion” means a portion having a relatively low strength compared to the adjacent portion, and is preferably formed on the absorbent body having the highest rigidity among the constituent members of the urine pad. For example, a structure in which a thin portion or a punched portion (penetrating portion) is formed as a fragile portion at a position that becomes a fold when the absorbent body is folded is preferable.

  In addition, since the “fragile part” only needs to have a relatively low strength compared to the adjacent part, the weak part can be weakened by increasing the strength relatively by, for example, hardening the adjacent part of the part desired to be the weak part. A part may be formed. For example, the part of the both sides of the width direction centerline of an absorber may be hardened by press work, and the intensity | strength of the part along the width direction centerline of an absorber may be made relatively low.

  Note that the “mountain fold shape” is a shape that is folded so that the top sheet 18 side of the pad is convex and the back sheet 20 side is concave with the width direction center line Lc as a fold, as in the urine pad 1A shown in FIG. 1D. Means. When viewed from the front end E1 side or the rear end E2 side, the urine pad 1A has a shape that is bent so that the end surface has an inverted V shape.

  The “valley fold shape” means a shape folded like a urine pad 1C shown in FIG. 3C so that the top sheet 18 side of the pad is concave and the back sheet 20 side is convex with the center line Lc in the width direction as a fold. To do. When viewed from the front end E1 side or the rear end E2 side, the urine pad 1C has a shape that is bent so that the end surface is V-shaped.

[2] Other components of the urine pad:
The urine pad of the present invention, like the urine pad 1A shown in FIGS. 1A to 1C, is arranged so as to cover the surface of the absorber 22 with at least a part made of a liquid-permeable material. A top sheet 18 and a back sheet 20 made of a liquid-impermeable material and arranged to cover the back surface of the absorber 22 are provided.

[2-1] Absorber:
The “absorber” is a member for absorbing and holding the wearer's urine and the like, and is made of an absorbent material. Usually, the absorber is sandwiched between a top sheet and a back sheet, and used in a state of being integrated with both sheets.

  Examples of the “absorbent material” include fluff pulp, super absorbent polymer (hereinafter referred to as “SAP”), a hydrophilic sheet, and the like. “Fluff pulp” is made by pulverizing wood pulp or non-wood pulp into cotton, “SAP” is sodium polyacrylate, “Hydrophilic sheet” is tissue, absorbent paper, hydrophilized It is preferable to use a non-woven fabric that has been treated.

  As the absorber, it is preferable to use one or two or more absorbent materials formed into a single-layer or multi-layer mat. Especially, what combined 10-500 mass parts SAP with respect to 100 mass parts of fluff pulp is preferable. At this time, the SAP may be mixed in the fluff pulp mat or used in a layered manner between the fluff pulp mats.

  The absorber can be used after being molded into a desired shape such as a rectangular shape, an hourglass shape, a gourd shape, or a T-shape. The absorber is preferably encapsulated with a hydrophilic sheet for the purpose of preventing SAP from falling off and imparting shape stability. A urine pad 1A shown in FIG. 1C is an example in which tissue is used as a hydrophilic sheet and the absorbent body 22 is encapsulated by an upper tissue 50 and a lower tissue 52.

[2-2] Top sheet:
Since the top sheet needs to allow the wearer's urine or the like to pass therethrough, at least a part (all or a part) of the top sheet is made of a liquid-permeable material.

  Examples of the “liquid permeable material” include woven fabric, non-woven fabric, and porous film. Among these, it is preferable to use a nonwoven fabric made of a thermoplastic resin such as polypropylene, polyethylene, polyester, aliphatic polyamide, etc., which has been subjected to a hydrophilic treatment.

  As the “nonwoven fabric”, a nonwoven fabric produced by a production method such as air through (card hot air) or card embossing can be suitably used. The “hydrophilic treatment” can be performed by applying, spraying, impregnating, etc. a surfactant.

  The top sheet is preferably “at least partly”, more specifically, when the top sheet is viewed in plan, at least the vicinity of the surface of the absorber is made of a liquid-permeable material.

[2-3] Backsheet:
The back sheet is a sheet disposed so as to cover the back surface of the absorbent body (the surface located on the side far from the wearer's skin when the urine pad is attached). The back sheet is made of a liquid-impermeable material because it is necessary to prevent the wearer's urine from leaking outside the urine pad.

  There is no restriction | limiting in particular about the arrangement position of a back seat | sheet. From the viewpoint of preventing leakage of urine absorbed by the absorber, it is preferable that a back sheet is disposed at least in a portion where the absorber exists.

  Examples of the liquid-impermeable material constituting the backsheet include a liquid-impermeable film made of a resin such as polyethylene. Among these, a microporous polyethylene film is preferably used. This microporous polyethylene film has a large number of fine pores of 0.1 to several μm, and is liquid impervious but has moisture permeability, so that the inside of the diaper can be prevented from being steamed There is.

  A cover sheet may be bonded to the outer surface side of the back sheet. This cover sheet is used to reinforce the back sheet and improve the feel (tactile feeling) of the back sheet.

  Examples of the material constituting the cover sheet include woven fabric and non-woven fabric. Especially, it is preferable to use the dry nonwoven fabric and wet nonwoven fabric which consist of thermoplastic resins, such as polyethylene, a polypropylene, and polyester.

[2-4] Solid gathering:
Urine pad of the present invention, as shown in FIGS. 1A and 1C, made water-repellent sheet 32, at least a pair of standing gathers 26 (26a, 26b) disposed on both sides of the absorbent body 22 be provided with a preferable.

  The structure used for the conventional disposable diaper and a urine pad can be employ | adopted for the structure of a three-dimensional gather. For example, as in the urine pad 1A shown in FIG. 1C, an elastic material (three-dimensional gather elastic material 36) is sandwiched and fixed between the layers of the water-repellent sheet 32, and the gathers (claws) are formed by the contraction force of the three-dimensional gather elastic material 36. What was formed can be used suitably. A urine pad 1 </ b> A shown in FIG. 1C is an example in which a three-dimensional gather stretchable material 36 is sandwiched and fixed to a folded portion of a water-repellent sheet 32. The water-repellent sheet may be a nonwoven fabric produced by a production method such as card embossing or spunbonding, but a nonwoven fabric sheet such as SMS or SMMS having a high waterproof property is more preferable.

  The three-dimensional gather may be separately provided with a water-repellent sheet for three-dimensional gather as described above, or may be formed by a part of the sheet material constituting the urine pad.

[2-5] Elastic material:
In the urine pad of the present invention, elastic materials may be arranged on both side edges and the like. By disposing this stretchable material, it is possible to form a gather that is rich in stretchability at both side edges of the urine pad. Therefore, it becomes difficult to form a gap at both side edges of the urine pad, and so-called side leakage can be effectively prevented.

  It is preferable that the elastic material is arrange | positioned in the part outside the standing line of a three-dimensional gather. With such a configuration, it is possible to improve the wearing feeling and wearing feeling of the crotch part while ensuring a sufficient leakage preventing effect of the three-dimensional gather.

  Regarding the stretchable material, the constituent material, the elongation rate of the material, the stretched state at the time of fixing, and the like may be determined in consideration of the degree of gather contraction and the like.

  As an elastic material, the elastic material used with the conventional disposable diaper and the urine pad can be used suitably. Specific examples include elastic rubber, elastic film, elastic foam (urethane foam, etc.), etc. in addition to natural rubber flat rubber and synthetic rubber (urethane rubber, etc.) elastic thread. it can.

  The stretchable material is preferably fixed in the stretched state in order to exert a sufficient stretch force. For example, when the elastic material is a flat rubber made of natural rubber or a thread rubber made of an elastic thread of synthetic rubber, it is preferably fixed in an extended state of 120 to 400%, and fixed in an extended state of 200 to 300%. More preferably. By fixing in the extended state in such a range, it is possible to apply a sufficient expansion / contraction force without applying an excessive tightening force to the wearer.

  The stretchable material as described above is fixed to other components of the urine pad by an adhesive or other means. The fixing method may be, for example, adhesion using a hot melt adhesive or other highly fluid adhesive, or may be welding by heat such as heat sealing or ultrasonic waves.

[3] How to use:
The urine pad of the present invention can be used as follows, for example. Hereinafter, in the description of FIG. 1E and FIG. 3D, the drawing back leg positioned below the human lateral position (referred to as "lower leg".), Located on the upper side of a person's lateral position in the drawings the front side leg (Denoted as “upper leg”) will be described.

  In the case of the urine pad 1A shown in FIGS. 1A to 1C, it is preferable to replace both the used pad and the unused pad in a mountain fold shape as shown in FIG. 1D. Specifically, as shown in FIG. 1E, in consideration of ease of visual recognition of the fastening material 54A, an area in which the fastening material 54A is previously attached to the lower leg side (the back side of the drawing) of the person in the lateral position. The urine pad 1A is inserted so that a region 58 where the fastening material 54A is not attached is located on the upper leg side (front side of the drawing) of the person in the lying position.

  In the inserted state, the fastening material 54A is easily visible from the upper leg side of the wearer. Therefore, when the urine pad is replaced, the surface of the unused pad 72A on the top sheet side is adhered to the fastening material 54A while visually confirming the fastening material 54A of the used pad 70A.
