Description

  The present invention relates to an absorbent article, and more particularly, to an absorbent article used by being disposed in a crotch portion of underwear.

  Absorbent articles such as sanitary napkins and incontinence pads are usually used by being placed inside the underwear, and often touch the skin of the wearer. For this reason, some have been devised to provide a good feeling when worn (for example, Patent Documents 1 and 2).

  In particular, Patent Document 1 describes a structure of a shorts that is a female underwear, in which a covering member is detachably attached to the inside of a crotch part of a shorts body. The covering member is made of the same fabric or non-woven fabric as the shorts from the viewpoint of reducing skin irritation. In this shorts body, an absorbent article can be sandwiched between the inner surface of the crotch part and the covering member, and an opening for communicating the body excretion part and the absorbent article is formed in the covering member. ing. This makes it possible to suppress the contact area of the absorbent article with the skin, and to maintain as much as possible the softness of the underwear on the skin.

JP 2002-345893 A Japanese Utility Model Publication No.59-28503

When an absorbent article is attached to the shorts as described above, the excretion point of the wearer and the opening may be shifted depending on the wearing state of the shorts and the movement of the wearer. At this time, the excretory fluid comes into direct contact with the shorts and causes dirt. Further, in the portion other than the opening, the absorbent article is in direct contact with the covering member of the shorts, so that the shorts may become dirty due to the return of the absorbed liquid.
Furthermore, depending on a wearing state, the liquid absorption surface of the absorbent article in the opening may be shifted in the middle to come into contact with the shorts, resulting in contamination. Even if the covering member can be replaced, depending on the wearing time and the amount of excretion, the liquid may ooze from the covering member to the shorts body, and the shorts body may become dirty. Even if the back surface and the opening of the covering member are coated with a liquid-impermeable resin film, etc., it is difficult to prevent contamination even if wetting can be prevented. Rather, because of the resin film, the diffusion of the liquid can be promoted on the shorts body side.

  The present invention relates to an absorbent article that can be used by being disposed in a two-layer structure portion of a crotch portion, and can prevent contamination of underwear during wearing as described above.

The present invention is an absorbent article in which the crotch portion is a two-layer structure part composed of a skin-contacting surface side surface and a non-skin-contacting surface side lining, and is used in combination with an underwear having an opening in the surface. And
A surface sheet disposed on the skin contact surface side, a back sheet disposed on the non-skin contact surface side, and an absorber disposed between both sheets, and the skin contact surface together with the absorber Having a convex part protruding to the side,
The convex portion is a portion that protrudes from the opening when the absorbent article is disposed between the outer surface and the lining of the underwear, and can be positioned on the skin contact surface side of the outer surface, and the convex portion has a thickness. An upper part and a lower part in the direction, the upper part has a liquid-permeable part on the skin contact surface, and the convex part other than the liquid-permeable part and the skin of the absorbent article other than the convex part Provided is an absorbent article in which a liquid-permeable permeable shielding part is disposed on a contact surface.

  The absorbent article of the present invention can prevent stains on the underwear when used by being inserted into the two-layer structure portion of the crotch portion.

  An absorbent pad as a preferred embodiment of the absorbent article according to the present invention will be described in detail below with reference to the drawings.

In the present invention, unless otherwise specified, the side that contacts the human body is referred to as the skin surface side, the skin contact surface side, the surface side or the inside, the opposite side is the non-skin surface side, the non-skin contact surface side, It is called the back side or the outside. The direction positioned on the front side of the human body when worn is referred to as the front, and its end is referred to as the front end, and the direction positioned on the rear is referred to as the rear, and the end is referred to as the rear end. The direction connecting the front end portion and the rear end portion, that is, the direction extending from the wearer's abdominal side portion to the back side portion via the excretory portion corresponding region is referred to as a longitudinal direction or a longitudinal direction (Y direction) of the absorbent article. A direction orthogonal to the vertical direction is referred to as a width direction or a horizontal direction (X direction). Moreover, the normal line direction of the surface or back surface of an absorbent article is called thickness direction, and the quantity is called thickness.
Further, in the two-layer structure in the crotch portion of the underwear, the fabric on the side in contact with the skin is referred to as the outer fabric, and the outer fabric is referred to as the lining.

  The absorptive pad of each embodiment shown below has a convex portion 5 on the skin contact surface side, and a liquid-permeable shielding portion 81 is provided on the lower portion of the convex portion 5 and the skin contact surface other than the convex portion. (Refer to FIGS. 1 and 2). The combination of the convex portion 5 and the poor liquid permeability 81 effectively prevents the undergarment (shorts 100) on which the absorbent pad is disposed, and provides a good wearing feeling. Hereinafter, the first embodiment will be described in order.

1 and 2 show an absorbent pad 10 as a first embodiment. The absorbent pad 10 has a liquid retaining absorbent 3 inside. More specifically, the liquid permeable top sheet 1 disposed on the skin contact surface side, the back sheet 2 disposed on the non-skin contact surface side, and the liquid holding disposed between the two sheets. A sex absorber 3 is provided. The absorbent pad 10 in the present embodiment is, for example, a sanitary napkin that absorbs and holds viscous liquid such as menstrual blood, an incontinence pad that absorbs and holds urine, and the like.
As shown in FIG. 3, the absorbent pad 10 is used by being disposed between a surface material 101 and a lining material 102 in a crotch portion of shorts 100 as underwear.

  The top sheet 1 is made of a liquid-permeable member that has a good touch and is made of, for example, a hydrophilic air-through nonwoven fabric. From the viewpoint of preventing liquid leakage on the non-skin contact surface side of the absorbent body 3, the back sheet 2 is made of a liquid hardly permeable member, for example, formed using a liquid hardly permeable porous film or the like. It is. Moreover, it is preferable to have moisture permeability from a viewpoint of preventing stuffiness. “Liquid-permeability” means a property that hardly allows liquid to pass through, and includes waterproofness, water repellency, and liquid impermeability. The absorbent body 3 is obtained by covering a laminated fiber body of hydrophilic fibers or a mixed fiber body of hydrophilic fibers and a superabsorbent polymer with a hydrophilic covering sheet (not shown).

The absorptive pad 10 has the convex part 5 which protruded to the skin contact surface side with the absorber 3. FIG. As shown in FIG. 2, the convex portion 5 has a base portion 55 with respect to the flat surface 6 on the skin contact surface side of the absorbent pad 10 (hereinafter, this portion is also referred to as a skin contact surface 6 other than the convex portion 5). It stands up from and protrudes upward on the skin contact surface side. In this embodiment, the convex part 5 is made into hemispherical shape in the center position of the front and back, and right and left of an absorptive pad. The above flat surface refers to a flat portion as a whole as compared with the convex portion 5, and may have a partial depression such as a leak-proof groove.
In addition, the shape, size, and arrangement position of the convex portion 5 of the present embodiment are shown as an example, and the present invention is not limited to this. As long as the effects described later are exhibited, a form suitably combined with underwear such as shorts can be arbitrarily employed. Moreover, according to the intended purpose or application of the absorbent article, the size, shape, and position of the convex portion can be appropriately changed as an aspect that fits the wearer's excretion point accurately.

As shown in FIGS. 3 and 4, the absorbent pad 10 having the convex portion 5 is used by being disposed between the outer surface 101 and the lining 102 in the crotch portion of the shorts 100. At the time of the arrangement, the convex portion 5 is a portion that protrudes from the opening portion 105 of the surface material 101 and can be positioned on the skin contact surface side with respect to the surface material 101. The opening 105 of the shorts 100 corresponds to the excretion point of the wearer and is disposed as an excretion liquid intake port. The convex part 5 of the absorbent pad 10 of this embodiment is formed so that it may enter into the opening part 105 corresponding to this excretion point. The convex part 5 becomes a liquid intake part of the absorbent pad 10 at the time of use.
In the state where the convex portion 5 protrudes from the opening portion 105, the opening peripheral edge portion 106 is located outside the base portion 55 of the convex portion 5, overlapped with the base portion 55, and inside the base portion 55. Any of the states applied to the inclined surface of the convex portion 5 may be used. That is, not only when the whole convex part 5 is located in the skin contact surface side rather than the surface material 101, the case where a part of convex part 5 is hidden by the surface material 101 may be sufficient.

In this state, when the wearer wears the shorts 100, the protruding convex portion 5 of the absorbent pad 10 hits the skin preferentially over the outer fabric 101. Thereby, positioning with the absorbent pad 10 and a wearer's excretion point is made exactly. That is, since it is not alignment with the conventional opening part 105 and skin but alignment with the convex part 5 and skin, the shift | offset | difference of a wearer's excretion point and the liquid intake part of the absorptive pad 10 does not arise easily.
Moreover, the convex part 5 has high fitting property to a wearer's drainage point. That is, even if the fabric of the shorts 100 may be worn when worn, the convex portion 5 having a height and having the rigidity of the absorbent body 3 is firmly attached to the skin and is not easily displaced. In addition, it is difficult to come off the opening 105 at the height of the convex part 5 itself, and a deviation from the excretion point hardly occurs.

Thus, the convex part 5 fitted to the wearer's excretion point directly receives excretion fluid such as menstrual blood and urine at a position closer to the skin than the outer surface 101. And the excretory fluid moves to the inside of the lower absorbent body without touching the outer surface 101 of the shorts and is absorbed and held. Thereby, contact with excretion fluid and shorts 100 is avoided, and dirt of shorts 100 is prevented.
Moreover, since the skin contact surface other than the convex part 5 is coat | covered with the surface material 101 of the shorts 100, the absorptive pad 10 can feel the softness of the shorts 100 unique to skin, and is excellent in a feeling of wear.

  Further, the absorbent pad 10 is provided with a liquid-impervious shielding portion 81 on its skin contact surface. Specifically, a liquid-permeable shield is provided on the lower portion 51 of the thickness (LM) of the convex portion 5 (see FIG. 11A) and the skin contact surface 6 of the absorbent pad 10 other than the convex portion 5. A portion 81 is provided. The liquid poor permeability means a property that hardly allows liquid to pass through, and includes waterproofness, water repellency, and liquid impermeability. The liquid hardly permeable shielding part 81 can be formed by a method used for this type of article. For example, a method of applying a water repellent oil or the like to the skin contact surface of the liquid permeable top sheet 1, a method of bonding a non-liquid permeable film, and the like can be mentioned.

  The disposition range of the lower liquid-permeable shielding part 81 in the lower part 51 may be the whole lower part 51 defined below or a part thereof. Alternatively, depending on the shape of the convex portion 5, the lower portion 51 may be extended to a part of the upper portion 52. At least from the viewpoint of preventing stains on the shorts due to liquid return described later, it is preferable that the shorts 100 are disposed up to a position higher than the height of the opening peripheral edge 106 in the state of being disposed on the shorts 100. Moreover, the outer edge of the arrangement range in the plane direction of the liquid-impermeable shield 81 is on the entire skin contact surface 6 of the absorbent pad 10 other than the convex portion 5 (skin contact surface 6 of the topsheet 1). It may extend to a part of it. For example, since the liquid diffusion range in the absorbent body varies depending on the viscosity of the liquid, the assumed liquid amount, and the like, it can be appropriately set as a range that can effectively prevent liquid return to the shorts 100 described later. Furthermore, the arrangement range in the thickness direction of the liquid-impermeable shield 81 is not particularly limited, and is set in a range that does not impair the liquid retention of the absorber 3.

  The lower part 51 is a lower part from half of the thickness (LM) of the convex part 5 measured by the following measuring method. The upper half is referred to as the upper portion 52. That is, the upper part 52 is a part including the top part of the convex part 5 and its periphery, and taking in excretion fluid directly in contact with the wearer's skin. In addition, the said top part is the part which protruded to the skin contact surface side of the convex part 5, and may be a part which has a vertex, and may be a flat surface without a vertex.

(Measurement method of thickness of convex part)
In the present invention, the thickness of the convex portion 5 is obtained by the following method unless otherwise specified. That is, as a measuring method, a value obtained by measuring the convex portion 5 under a load of 0.245 KPa with a laser thickness meter (trade name: LK-080) manufactured by Keyence Co., Ltd. The difference when measured under a load of 41 KPa. The above load assumes a load applied to the convex portion 5 and a load applied to a flat portion other than the convex portion 5 due to the wearer's body pressure or the like in the wearing state of the shorts 100.

  The thickness of the convex part 5 specified by the above measurement method is a thickness generated by two kinds of pressure differences. From this, the absorbent pad having the convex portion 5 measured by the above measurement method includes an absorbent pad in which the convex portion 5 is generated due to a load difference of body pressure even when there is no thickness difference at the time of non-pressurization. It is.

  On the other hand, the upper part 52 of the convex part 5 has a liquid permeable part 82 on the skin contact surface as a liquid intake part. The liquid permeable portion 82 is a portion of the convex portion 5 where the liquid permeable shielding portion 81 of the top sheet 1 is not disposed. That is, the liquid permeable portion 82 and the liquid permeable shielding portion 81 are continuously arranged on the skin contact surface of the convex portion 5. The boundary exists at the boundary between the lower part 51 and the upper part 52, or at the lower part 51 or the upper part 52. This is determined by the arrangement range of the liquid poorly permeable shielding part 81 in the convex part 5. The liquid-permeable shielding portion 81 is disposed at least on the skin contact surface of the absorbent pad (the uppermost surface that comes into contact with the shorts). As long as it is possible to prevent contact with the shorts 100 due to the return, it is not always necessary to exist on the entire surface in the thickness direction.

The liquid-impervious shielding portion 81 further ensures the anti-dirt property of the shorts by the convex portion 5 described above. That is, the liquid-impervious shielding portion 81 prevents contact with the shorts 100 due to the return of excretory liquid absorbed and held inside the absorbent pad 10 and prevents dirt.
More specifically, in the absorbent pad 10, a portion that can come into contact with the opening peripheral edge portion 106 of the shorts 100 and the non-skin contact surface 101 </ b> B of the outer fabric 101 is used as a liquid-impervious shielding portion 81. Thereby, even if the liquid moves from the inside of the absorbent pad 10 to the skin contact surface side, the liquid cannot ooze on the skin contact surface of the absorbent pad, and the liquid onto the outer surface 101 of the shorts 100 Will be blocked. As a result, while the shorts 100 are worn, even if it is worn for a long time, the transition of the liquid to the shorts 100 is suppressed, and the shorts 100 are prevented from being soiled.
This cannot be obtained by making the non-skin contact surface side 101B of the outer material 101 liquid impervious in conventional shorts. This is because the absorbent pad 10 of the present embodiment blocks the contact between the shorts and the liquid itself (see FIG. 5 (A)), whereas the liquid impermeability on the conventional shorts side is the dough and the excretory liquid. This is because the contact itself cannot be blocked (see FIG. 5B), and the adhesion of dirt and the outflow of liquid on the surface of the shorts cannot be prevented. Therefore, the absorptive pad 10 of this embodiment has an excellent liquid blocking action that has not been achieved in the past. In the cross-sectional view of FIG. 5, only the outer shape of the absorbent pad 10 is shown by a solid line to avoid complexity, and the configuration of each member is omitted (the same applies to the cross-sectional views of FIG. 6 and subsequent figures). .)

  The arrangement of the liquid-impermeable shield 81 described above is a configuration that can be taken because it is an absorbent article that is disposed within the two-layer structure of the shorts and takes in excretion liquid only by the convex portion 5 instead of the entire surface sheet. is there. If it is a normal absorbent article, it is arranged on the inner surface of shorts or the like, and tries to receive the excretion fluid on the entire skin contact surface side. Cannot be placed.

Next, the absorbent pad 20 as a second embodiment will be described with reference to FIGS.
The absorbent pad 20 of the second embodiment includes the convex portion 5 of the first embodiment and a liquid-impervious shielding portion 81, and the fixing means 7 is disposed on the skin contact surface side. The fixing means 7 can adopt various means for releasably fixing this kind of article to clothes or the like, and can be formed by, for example, applying a hot melt adhesive or attaching a surface fastener. . The adhering means 7 is disposed on the skin contact surface 6 other than the convex portion 5 of the absorbent pad 20, which is in contact with the non-skin contact surface 101 </ b> B of the outer material 101 of the shorts 100.

The absorbent pad 20 is fixed to the non-skin contact surface 101 </ b> B of the surface material 101 by the fixing means 7 when being arranged on the shorts 100. Thereby, the arrangement | positioning shift | offset | difference of the convex part 5 and the opening part 105 is prevented, and it is preferable. This effect cannot be obtained by a non-skin contact surface side misalignment stop portion used in a conventional absorbent article. When it is fixed to the lining 102 on the non-skin contact surface side like a conventional absorbent article, the convex portion 5 and the opening portion when the outer surface 101 shows a movement that does not interlock with the lining 102 due to some force. This is because misalignment with 105 cannot be prevented.
The absorbent pad 20 of the present embodiment prevents even unexpected dirt due to the misalignment between the convex portion 5 and the opening portion 105, which cannot be achieved by a conventional absorbent article.

On the other hand, it is preferable that the non-skin contact surface side of the absorbent pad 20 has the liquid-permeable back sheet 2 and the non-skin contact surface side does not have fixing means for the shorts 100. Thus, the back sheet 2 does not have a fixing means, and can be reliably fixed while suppressing the fixing area by the fixing means 7 on the skin contact surface side, and the air permeability on the back sheet 2 side due to the HM of the fixing means 7 is reduced. Is suppressed. Moreover, arrangement | positioning of the absorptive pad 20 between the surface material 101 of the shorts 100 and the lining 102 becomes easy. That is, unintentional sticking between the back sheet 2 and the shorts 100 during the placement operation can be avoided, and accurate placement is possible. This action is effective both when the outer material 101 and the lining material 102 are integrated as a structure of the shorts 100 and when the outer material 101 is detachable. That is, when the outer material 101 and the lining 102 are integrated, the absorbent pad 20 is inserted between the two fabrics, but there is no unnecessary sticking between the back sheet 2 and the lining 102. Further, when the outer surface 101 is detachable, the absorbent pad 20 is fixed to the outer surface 101 after being fixed to the outer surface 101 by the fixing means 7, but there is no unintentional sticking to the inner surface 102 at that time. As a result, accurate installation can be achieved and reliable positioning is possible.
Furthermore, since the back sheet 2 and the lining 102 are not fixed, it is difficult for a force such as a sag of the lining 102 to be transmitted to the absorbent pad 20 with the shorts 100 worn. Thereby, the maintainability of arrangement | positioning with the convex part 5 and the opening part 105 further increases.

In addition, it is preferable that the fixing means 7 is provided at a position where it can be adhered to the outer side of the opening peripheral edge 106 of the shorts 100 in the arrangement state on the shorts 100. That is, it is preferable that the fixing means 7 is provided on the skin contact surface 6 of the absorbent pad 20, not on the corresponding position of the opening peripheral edge 106, but on the outer side. Thereby, the absorptive pad 20 can be firmly fixed to the non-skin contact surface 101B of the outer surface 101 of the shorts 100 with a certain area.
Furthermore, since the fixing means 7 is provided outside the opening peripheral edge 106, the fixing means can be comfortably mounted without touching the skin.
Specific examples thereof include FIGS. 7A to 7D. However, the arrangement of the fixing means 7 is not limited to this specific example as long as it is the above-described embodiment. 7A to 7D project the opening peripheral edge 106 when arranged on the shorts 100 on the skin contact surface of the absorbent pad 20 and indicate them by a one-dot chain line (hereinafter, FIG. 7). 8 (C), FIG. 9, FIG. 11 (B) and (C) also show the same).

  7A, the adhering means 7 (7A) is disposed in the vicinity of the outside of the opening peripheral edge 106 so as to surround the opening peripheral edge 106 with a predetermined width. The shape is an ellipse similar to the opening peripheral edge 106. By this fixing means 7 </ b> A, the absorbent pad 20 is firmly fixed to the outer surface 101 of the shorts 100 in the vicinity of the opening 105 and the convex portion 5. As a result, the floating due to the deformation of the surface material 101 in the vicinity of the opening 105 and the convex portion 5 hardly occurs, and the misalignment between the convex portion 5 and the opening 105 hardly occurs. Further, since the position area of the fixing means 7A is limited, the absorbent pad 20 can be accurately installed on the shorts. Furthermore, since the fixing area is suppressed, a decrease in air permeability can be suppressed. Also, the uncomfortable feeling due to the thickness of the fixing means can be reduced.

  FIG. 7B is a mode in which the fixing means 7B is further added to the fixing means 7A in FIG. The fixing means 7B are disposed at the four corners of the skin contact surface of the absorbent pad 20. In this aspect, it is preferable because the fixing force of the entire absorbent pad 20 to the surface material 101 is increased while suppressing the fixing area. Further, since the four corners are fixed, the absorbent pad does not protrude from the surface material 101 and does not get dirty from there. Moreover, the shift | offset | difference of the absorptive pad whole is suppressed, and a feeling of fitting improves.

  In FIG. 7C, instead of the fixing means 7A, four fixing means 7C are disposed so as to surround the opening peripheral edge 106 outside the opening peripheral edge 106. In this case, it is suitable for the case where the absorbent pad is arranged in shorts where the opening 105 is not so large. That is, when the opening 105 is small, the area of the outer surface 101 to be fixed around the opening 105 is small, and therefore, the floating of the outer surface 101 can be prevented with a small fixed area. Thereby, the uncomfortable feeling due to the thickness and hardness of the fixing means is reduced. Further, since the fixing area can be minimized, air permeability is improved, which is preferable.

  In FIG. 7D, the fixing means 7 </ b> D is disposed on the entire skin contact surface of the absorbent pad 20 outside the opening peripheral edge 106 at a predetermined width. This embodiment is preferable because the adhering force between the absorbent pad 20 and the outer material 101 of the shorts 100 is high, and the displacement of the arrangement can be greatly suppressed. Moreover, since the fixing means 7D is disposed on the entire skin contact surface of the absorbent pad 20 outside the opening peripheral edge portion 106 by a predetermined width, there is no sense of a step at the fixing means 7D. By suppressing the step, it is difficult for a gap to be formed between the outer surface 101 and the fixing means 7D, and stable fixing is possible.

  In the above specific example, the shape of the opening peripheral edge portion 106 is a long oval shape that is long in the longitudinal direction (Y direction) of the absorbent pad 20, and the arrangement of the fixing means 7 corresponding to this is shown. In the present embodiment, if the opening peripheral edge 106 is different, the shape of the fixing portion 7 can be deformed accordingly.

Next, an absorbent pad 30 as a third embodiment will be described with reference to FIGS.
The absorbent pad 30 of 3rd Embodiment is provided with the convex part 5 of 1st Embodiment, and the liquid-permeable shielding part 81, and the convex part 5 is a mushroom shape in a cross section. This mushroom shape means that when the absorbent pad 30 is viewed in plan, the outer peripheral edge portion 56 (mushroom umbrella) is larger than the outer peripheral edge 55A of the convex base composed of the base portion 55. This is a shape having a portion). That is, the outer peripheral edge 56 </ b> A of the bevel part 56 that forms the top of the convex part 5 is larger than the outer peripheral edge 55 </ b> A of the base part 55.
When viewed from the side, the maximum width H1 of the outer peripheral edge 56A of the umbrella portion 56 is wider than the width H3 of the outer peripheral edge 55A of the base portion 55 at that position. In other words, the side wall portion 58 formed of the non-skin contact surface 56B of the umbrella portion 56 or the side wall portion 58 formed of the peripheral surface of the non-skin contact surface 56B and the handle 57 is spread outward and opened as a whole.
The maximum width H1 of the outer peripheral edge 56A of the above-described umbrella portion 56 is a width of a portion having a longest diameter corresponding to a circle when the umbrella portion 56 is viewed in plan. The maximum width H1 is preferably in the longitudinal direction (Y direction) of the absorbent pad 30 from the viewpoint of preventing the shorts 100 from being soiled and preventing liquid leakage.

  As a specific example of the mushroom shape, for example, the example of FIG. In FIG. 8A, the side wall portion 58 includes the non-skin contact surface 56 </ b> B of the bevel portion 56. The side wall portion 58 crosses at an acute angle with the base portion 55 as an intersection with respect to the plane of the skin contact surface 6 of the absorbent pad 30 and spreads outward. That is, a V-shape is formed by the flat surface of the skin contact surface 6 and the side wall portion 58 starting from the base portion 55. In FIG. 8B, the side wall portion 58 includes a non-skin contact surface 56 </ b> B of the bevel portion 56 and a peripheral surface of the handle 57. In the side wall portion 58, the handle 57 rises perpendicularly at the base end portion 55 with respect to the plane of the skin contact surface 6 of the absorbent pad 30, while the non-skin contact surface side 56 </ b> B of the umbrella portion 56 faces outward. Spreading. In either case, the side wall 58 as a whole has a shape that opens outward rather than inside the convex portion 5.

  In the absorbent pad 30, since the convex part 5 is mushroom-shaped, the area which touches skin as a liquid intake part becomes large, fitting to an excretion point. Thereby, the collection property of excretion liquid improves, and a liquid leak and the stain | pollution | contamination of the shorts 100 by it are prevented and preferable. Moreover, since the bevel part 56 is larger than the side wall part 58 of the convex part 5, it is difficult to come out when the convex part 5 enters the opening part 105, and it is preferable because it can take in excretion fluid accurately and prevent the shorts 100 from being stained. Furthermore, even when the convex portion 5 enters the opening 105 and deviates from the initial arrangement position, exposure of the skin contact surface 6 of the absorbent pad 30 can be suppressed by the size of the umbrella portion 56. Thereby, in the opening part 105, excretion liquid does not enter easily into the clearance gap between the surface material 101 of the shorts 100, and the absorptive pad 30, and it is preferable from a viewpoint of the stain | pollution | contamination prevention of the shorts 100.

  In the mushroom-shaped convex part 5, it is preferable that the liquid-permeable shielding part 81 extends to the side wall part 58. Thereby, the stain | pollution | contamination prevention property of the shorts 100 in the process of taking in excretion fluid by the convex part 5 further improves. In this case, although the arrangement region of the liquid-impermeable shield 81 depends on the height of the mushroom-shaped umbrella 56, the lower part of the convex part 5 described above (the lower half of the thickness of the convex part 5). In some cases, it may remain within the range, or in some cases, the upper portion (the upper half of the thickness of the convex portion 5) may be exceeded.

It is more preferable that the above-mentioned mushroom-shaped convex portion 5 has a shape that makes it difficult for the mushroom-shaped convex portion 5 to be removed from the opening 105, and the convex portion 5 has the following configuration with respect to the opening 105. That is, it is preferable that the shape of the convex portion 5 in plan view has a portion larger than the outer shape of the opening 105 of the shorts. Further, when the absorbent pad 30 is disposed on the shorts 100, it is preferable that the shape of the top portion of the convex portion 5, which is a plan view shape of the umbrella portion 56, can cover at least a part on the skin contact surface side of the opening 105. . More specifically, it is preferable that the outer peripheral edge 56A of the umbrella 56 has a portion larger than the opening peripheral edge 106 of the shorts in plan view. This large portion is not limited to the entire outer peripheral edge of the bevel portion 56 but may be at least partially. In this embodiment, the umbrella portion 56 does not fit into the opening portion 105 as it is when placed on the shorts 100, but is large enough to be taken out and exposed to the skin contact surface side of the opening portion 105. Have.
As this example, it is mentioned that the maximum width H1 of the bevel 56 of the convex part 5 is larger than the width H2 of the opening 105 at that position (see FIGS. 8A and 8B). The relationship between H1 and H2 is not limited to the entire outer peripheral edge 56A of the umbrella portion 56, but may be a part thereof.

  As an aspect of the above-described “having a portion larger than the outer shape of the opening 105 of the shorts”, an aspect in which the entire planar shape of the bevel portion 56 of the convex portion 5 is larger than the opening peripheral edge 106 of the shorts is one preferable embodiment. (See FIG. 8C). In this aspect, even if the convex portion 5 entering the opening 105 tries to move in various directions, the convex portion 5 having a mushroom shape is preferable.

  In addition to this mode, a mode in which a part of the convex portion 5 “has a portion larger than the outer shape of the opening 105 of the shorts” may be used (hereinafter, this portion is also simply referred to as a “large portion”). For example, as shown in FIG. 9, there is one portion in the longitudinal direction (Y direction) of the absorbent pad 30 that has the maximum width H <b> 1 of the umbrella portion 56, and this width H <b> 1 is the opening 105 of the shorts at that location. The aspect which becomes a "larger part" than width H2 of this is mentioned. Alternatively, there may be a mode in which there are a plurality of “large portions”, such as a mode in which the “large portions” are arranged in a cross shape orthogonal to both the vertical direction and the width direction. Further, the shape may not be symmetrical as shown in FIGS. 8A and 8B, and only one side may be a “large portion”. In this embodiment, “the portion larger than the opening peripheral edge portion 106 of the shorts” is formed by arranging the absorbent pad 30 in the two-layer structure portion of the shorts 100, and the center point of the opening portion 105 and the center point of the convex portion 5. It is a part shown by planar view in the state which matched.

  Furthermore, the aspect illustrated in FIG. 10 is included as an aspect “having a portion larger than the outer shape of the opening 105 of the shorts” (FIG. 10). That is, after the absorbent pad 30 is correctly placed on the shorts 100 (FIG. 10A), even if there is a displacement due to external force during use (FIG. 10B), one end of the “large portion” is This is an aspect that remains outside the opening peripheral edge 106. Thereby, the bevel part 56 of the convex part 5 remains on the skin contact surface side of the opening part 105, and is difficult to come off from the opening part 105.

  The absorbent pad 30 of the third embodiment can be combined with the fixing means 7 in the second embodiment as appropriate. In addition, in the absorbent pad 30, when the bevel part 56 is sufficiently large with respect to the opening part 105, this can prevent misalignment and the fixing means 7 may be omitted. In this case, the absence of the adhering means 7 is preferable because accurate mounting can be quickly performed while securing the placement stability of the absorbent pad 30.

  Next, a preferred numerical range in the first to third embodiments will be described with reference to FIG. As shown in the cross-sectional view of FIG. 11A, the height (LM) of the convex portion 5 of the absorbent pad common in the first to third embodiments is preferably 5 mm or more, more preferably 7 mm or more. 9 mm or more is more preferable. Thereby, adhesiveness with an excretion point will go up. The upper limit is preferably 15 mm or less, and more preferably 13 mm or less. More preferably, it is 12 mm or less. Thereby, the uncomfortable feeling at the time of mounting | wearing will reduce.

On the other hand, the size of the convex portion 5 in plan view differs depending on the intended use and application of the absorbent article, and thus cannot be generally determined. For example, a urine absorbing pad or incontinence pad having a shape similar to a sanitary napkin can be used. In this case, the following range is preferable. That is, as shown in the plan view of FIG. 11B, the length (H) in the longitudinal direction (Y direction) of the convex portion of the absorbent pad is preferably 2 cm or more, more preferably 3 cm or more, and 5 cm or more. Further preferred. Further, the length (G) in the width direction (X direction) of the convex portion is preferably 1 cm or more, and more preferably 2 cm or more. Thereby, the collection property of an excretion point goes up.
On the other hand, the upper limit of the length (H) in the vertical direction (Y direction) of the convex portion is preferably 33 cm or less, more preferably 18 cm or less, and even more preferably 11 cm or less. Further, the upper limit of the length (G) of the convex portion in the width direction (X direction) is preferably 13 cm or less, more preferably 9 cm or less, and still more preferably 7 cm or less. Thereby, the contact area to the skin of an absorptive pad can be reduced by the crotch width equivalent to a general underwear.

Further, the size of the opening 105 in plan view is different depending on the purpose of use or application of the absorbent article, as in the case of the convex portion 5, and thus is not generally defined. For example, the opening 105 has a shape similar to that of a sanitary napkin In the case of a urine absorption pad or an incontinence pad, the following ranges are preferable. That is, as shown in the plan view of FIG. 11C, the length (R) of the opening 105 in the vertical direction (Y direction) is preferably 3 cm or more, more preferably 4 cm or more, and further preferably 6 cm or more. The length (P) of the opening 105 in the width direction (X direction) is preferably 2 cm or more, and more preferably 3 cm or more. Thereby, it becomes easy to take out the absorptive pad which has a convex part which can cover an excretion point.
On the other hand, the upper limit of the length (R) in the longitudinal direction (Y direction) of the opening 105 is preferably 30 cm or less, more preferably 15 cm or less, and still more preferably 8 cm or less. Further, the upper limit of the length (P) in the width direction (X direction) of the opening 105 is preferably 10 cm or less, more preferably 6 cm or less, and still more preferably 4 cm or less. Thereby, it is not necessary to reduce the skin contact area of the underwear.

The difference between the size of the protrusion 5 and the size of the opening 105 is preferably in the following range. That is, the difference (HR) in the vertical direction (Y direction) is preferably 1 cm or more in total in the front and rear ends. Moreover, 0.5 cm or more is preferable at least on one side of the front and rear ends. Thereby, it is possible to prevent the excretion liquid from being dropped. On the other hand, the upper limit of the difference (HR) in the longitudinal direction (Y direction) is preferably 3 cm or less in total in the front and rear ends. Further, it is preferably at least 1.5 cm on one side of the front and rear ends. Thereby, in the state which covered the opening part enough, the uncomfortable feeling at the time of mounting | wearing can be reduced.
Furthermore, the difference (GP) in the width direction (X direction) between the convex portion 5 and the opening portion 105 is preferably 1 cm or more in total in the front and rear ends. Moreover, 0.5 cm or more is preferable at least on one side of the front and rear ends. Thereby, it is possible to prevent the excretion liquid from being dropped. On the other hand, the upper limit of the difference (GP) in the width direction (X direction) is preferably 3 cm or less. Further, it is preferably at least 1.5 cm on one side of the front and rear ends. Thereby, in the state which covered the opening part enough, the uncomfortable feeling at the time of mounting | wearing can be reduced.

Furthermore, in this embodiment, it can also provide as a kit which combined the various absorptive pad mentioned above and the said shorts. If the kit is a combination of an absorbent pad having a suitable convex part and a liquid-permeable shielding part with respect to the size of the two-layer structure part and the opening part of the shorts and the position where the opening part is formed, the convex part As a result, the retention of the arrangement position between the opening and the opening is enhanced, and the anti-dirt property of the shorts is excellent. In particular, for the absorbent pad 30 having the mushroom-shaped convex portion having the “part larger than the outer shape of the opening portion 105 of the shorts” of the third embodiment, the shorts having the opening portion 105 that matches the convex portion are combined. Kits are preferred.
The “kit” here includes various patterns such as a combination in which the number of absorbent pads and shorts (including one and a plurality) matches, and a combination in which either one is more than the other. For example, a plurality of absorbent pads may be combined for one short. In the case where a plurality of absorbent pads are used, the kit may include, in part, a complex in which the absorbent pads are attached to the shorts.

  As a material for forming the top sheet 1, the back sheet 2, and the absorber 3 used in the above absorbent pad, those employed for this type of article can be used without particular limitation.

  For example, the surface sheet 1 is preferably a hydrophilic thermal bond nonwoven fabric from the viewpoint of promptly absorbing excreted bodily fluid and transmitting it to the absorbent body and from the viewpoint of good touch, and particularly preferably an air-through nonwoven fabric. The surface layer 1 is preferably a thermoplastic resin fiber that has been subjected to a hydrophilic treatment, and the fiber is a fiber that has undergone a three-dimensional crimp such as a secondary crimp or a tertiary crimp. Specifically, polyethylene, polypropylene, polyester, nylon, and composite fibers thereof are prepared, and various hydrophilizing agents are applied at a stage before cutting into a predetermined length to form staples. Hydrophilic agents include various alkyl sulfonates represented by α-olefin sulfonates, acrylates, acrylate / acrylamide copolymers, ester amides, ester amide salts, polyethylene glycol and derivatives thereof, water-soluble Hydrophilic treatment with a hydrophilizing agent known to those skilled in the art, such as a reactive polyester resin, various silicone derivatives, various sugar derivatives, and mixtures thereof, can be used.
