(1) Outline of Embodiments At least the following matters will become apparent from the description of the present specification and the accompanying drawings.

  According to the absorbent article which concerns on one Embodiment, the 1st wing 41 has the tear induction | guidance | derivation part 80 extended in the front-back direction L, the outer side wing junction part 61 located in the outer side rather than the tear induction | guidance | derivation part 80 in the width direction W, And an inner wing joint 63 positioned inside the tear guide 80 in the width direction W.

  In such an absorbent article, even if the side part in the width direction W of the first wing 41 is unintentionally separated through the tear guiding part 80 before use, the remaining first wing remains on the main body part 2 side. The first inner wing joint 63 exists in the portion. Therefore, the first inner wing joint 63 can be attached to the underwear. Therefore, even if the side part of the width direction W of the 1st wing 41 is torn unintentionally via the tear induction | guidance | derivation part 80, the user can attach the absorbent article 1 to underwear and can use it.

  In the first mounting state and the second mounting state, the tear guiding portion 80 is sandwiched between the first inner wing bonding portion 63 and the first outer wing bonding portion 61. Therefore, it is suppressed that the area | region of the tear induction | guidance | derivation part 80 of the 1st wing 41 floats from underwear during wear of an absorbent article. Thereby, it can suppress that the area | region of the tear induction | guidance | derivation part 80 of the 1st wing 41 rubs against outers, such as pants. As a result, it is possible to prevent the first wing from being unintentionally torn through the tear guiding portion 80 during wearing of the absorbent article.

  According to the embodiment, in the unfolded state of the first wing 41 and the second wing 42, the distance D13 between the base end portion 41BE of the first wing 41 and the base end portion 42BE of the second wing 42 is the first. The sum of the distance D16 between the outer edge of the inner wing joint 63 and the proximal end of the first wing 41 and the distance D17 between the outer edge of the second wing 42 and the proximal end of the second wing Longer than the value. Thereby, in the 2nd wearing state (Drawing 5 and Drawing 6), the 1st inner side wing joint part 63 is joined to underwear, without overlapping with the 2nd wing 42. Since the first inner wing joint portion 63 is not joined to the second wing 42, the first wing 41 and the second wing 42 are separated from each other when the user tears the tear guiding portion 80. Thereby, the user can remove an absorbent article from underwear easily also in a 2nd mounting state. In addition, since the first inner wing joint 63 is joined to the undergarment, the absorbent article in use can be more difficult to shift.

  According to one embodiment, the outer side edge in the width direction W of the first inner wing joint portion 63 extends in parallel with the tear guiding portion 80, and the inner side of the outer wing joint portion 61 in the width direction W is extended. The end side extends in parallel with the tear guiding portion 80. Thereby, in the first wearing state (FIGS. 3 and 4) and the second wearing state (FIGS. 5 and 6), the region of the tear guiding portion 80 is adjacent to the underwear in a uniform state. If the first inner wing joint portion 63 and the first outer wing joint portion 61 and the tear guiding portion 80 are not parallel to each other, a part of the region of the tear guiding portion 80 may easily float from the underwear. is there. In this case, there is a possibility that a part of the tear guiding portion 80 is unintentionally broken during wearing of the absorbent article. If a part of the tear guiding portion 80 is unintentionally broken, the entire tear guiding portion 80 may be unintentionally broken with the broken portion as a starting point. In the present embodiment, since the first inner wing joint portion 63 and the first outer wing joint portion 61 and the tear guide portion 80 are parallel to each other, the possibility that the tear guide portion 80 breaks unintentionally is reduced. be able to.

  According to one embodiment, the width of the first inner wing joint 63 in the width direction W is narrower than the width of the first outer wing joint 61 in the width direction W. Thereby, the bonding force of the first inner wing bonding portion 63 is smaller than the bonding force of the first outer wing bonding portion 61. Therefore, when the user tries to remove the absorbent article from the undergarment, the first inner wing joint 63 is first detached from the undergarment due to the pulling force of the absorbent article. If the 1st inner side wing joint part 63 remove | deviates from underwear, the force which pulls an absorbent article will become easy to be applied to the tearing induction part 80 of the 1st wing 41, As a result, the tearing induction part 80 will fracture | rupture. Thus, by narrowing the width of the first inner wing joint 63, the used absorbent article can be easily removed from the underwear.

  According to one embodiment, the first wing 41 has a convex constriction 70 toward the center in the front-rear direction L. The tear guiding portion is provided in the region of the constriction 70. The first wing 41 has a convex region 72 having a convex shape outward from the center in the front-rear direction of the first wing on the inner side in the width direction than the region of the constriction 70. When removing an absorbent article from underwear, a user grasps an end edge of main part 2 and pulls an end of main part 2 away from underwear, for example. When the main body 2 is separated from the underwear, the base ends of the pair of wings 41 and 42 are pulled toward the main body 2. A convex region 72 having a convex shape is provided on the inner side in the width direction from the region of the constriction 70 toward the outer side from the center in the front-rear direction L of the first wing 41. When the user pulls toward the main body 2, the convex region 72 swelled in the front-rear direction L pulls a portion on the outer side in the width direction than the convex region 72, that is, the region of the constriction 70 inward in the width direction. On the other hand, the wing overlap portion where the wings join each other in the width direction outside of the wings 41 and 42 resists the force pulled from the convex region 72 and stays on the non-skin surface side of the underwear. Power is applied to the overlapping part. The force applied to the wings 41 and 42 tends to concentrate on the position of the constriction 70 from the convex region 72 swelled in the front-rear direction L. Since the tear guiding portion 80 exists at the position of the constriction 70, the tear guiding portion 80 is easily torn by the force with which the wings 41 and 42 are pulled.

  According to one embodiment, the length of the first inner wing joint portion 63 in the front-rear direction L is longer than the length of the first outer wing joint portion 61 in the front-rear direction L. When removing the absorbent article from the underwear, for example, the user holds the edge of the main body 2 and pulls the end of the main body 2 away from the underwear (FIGS. 7A and 7B). reference). When a part of the main body 2 is separated from the underwear, the pair of wings 41 and 42 are pulled to the main body 2 side, and a force F1 pulled to the outer side W in the width direction is applied to the wing (FIGS. 7B and 7D). reference). Since the user pulls one of the front end edge and the rear end edge of the main body 2, the force F <b> 1 is biased to one of the front side or the rear side of the first wing 41. At this time, in a state where both the first inner wing joint portion 63 and the first outer wing joint portion 61 are joined to the undergarment, a state where a force is hardly applied to the tear guiding portion 80 is maintained. When the user further pulls the edge of the main body 2 and the first inner wing joint 63 comes off the underwear, the force F1 causes the front edge and the rear edge of the first inner wing joint 63 to Is instantaneously pulled up toward the main body 2. On the other hand, since the first wing 41 and the second wing 42 are firmly joined to each other at the first outer wing joint 61, the region of the first outer wing joint 61 resists the force F1. Attempts to stay at a stationary position with respect to the underwear S. As a result, at the moment when the first inner wing joint 63 is detached from the underwear, a force that is slightly twisted is applied to the region of the tear guiding portion 80. In particular, when the length of the first inner wing joint portion 63 in the front-rear direction L is longer than the length of the first outer wing joint portion 61 in the front-rear direction L, the force that deforms the first wing 41 to be twisted is It tends to be applied near the end portion of the tear guiding portion 80 in the direction L. Therefore, at the moment when the first inner wing joint 63 is detached from the underwear, the vicinity of the end portion of the tear guiding portion 80 is easily broken.

  According to one embodiment, the distance D11 between the first outer wing joint 61 and the tear guide 80 is shorter than the distance D12 between the base end of the first wing 41 and the tear guide 80. When the user pulls the main body 2 in a direction away from the undergarment, a tearing force is applied between the main body 2 and the first wing 41. Under a situation where the first inner wing joint portion 63 is detached from the underwear, a tearing force is likely to be applied to the first outer wing joint portion 61. Since the tear guiding portion 80 is located near the first outer wing joint portion 61 as compared with the base end portion of the first wing 41, the tearing force is efficiently applied to the tear guiding portion 80, and the first wing 41 is moved. It can be easily separated into two. Moreover, a wearer may trace a base end part of a wing at the time of wearing, and may attach a wing to underwear.

  According to one embodiment, in the unfolded state of the first wing 41 and the second wing 42, the distance D13 between the base end portion 41BE of the first wing 41 and the base end portion 42BE of the second wing 42 is the first wing 41. This is longer than the total value of the distance D12 between the base end portion 41BE and the tear guiding portion 80 and the distance D14 between the outer edge of the second outer wing joint portion 62 and the base end portion BE of the second wing 42. Thereby, the 2nd outer side wing junction part 62 and the tearing induction part 80 are spaced apart in the width direction W in a 1st mounting state. Since the second outer wing joint portion 62 and the tear guiding portion 80 do not overlap, the first wing 41 is easily torn through the tear guiding portion 80 and is smoothly separated into two.

  According to one embodiment, the first outer wing joint 61 is provided at a position overlapping the second wing 42 when the absorbent article is attached to the underwear, and the second wing 42 is formed from the absorbent article. Has a second outer wing joint 62 at a position overlapping with the first wing 41 in a state of being attached to the underwear. When the absorbent article is attached to the underwear, the first wing 41 and the second wing 42 are joined to each other on the non-skin surface side of the underwear by the first outer wing joint 61 or the second outer wing joint 63. can do. When removing the absorbent article from the underwear, the user grips the front end edge of the main body 2 and pulls the front end edge of the main body 2 away from the underwear, for example. When the main body 2 is separated from the underwear, the first wing 41 and the second wing 42 are dragged toward the main body 2 and a force that is pulled outward in the width direction is applied to the first wing 41. Due to the force applied to the first wing 41, the first wing 41 is torn through the tear guiding portion 80. When the side portion in the width direction W of the first wing 41 is separated, the side portion in the width direction W of the first wing 41 is second through the first outer wing joint portion 61 or the second outer wing joint portion 63. It continues to the wing 42. Therefore, the side part of the width direction W of the 1st wing 41 can be removed with the main-body part 2 by removing the main-body part 2 from underwear when removing an absorbent article from underwear.

(2) Structure of absorbent article With reference to FIG.1 and FIG.2, the absorbent article 1 which concerns on one Embodiment is demonstrated. In the following description of the drawings, the same or similar parts are denoted by the same or similar reference numerals. However, it should be noted that the drawings are schematic and ratios of dimensions and the like are different from actual ones. Therefore, specific dimensions and the like should be determined in consideration of the following description. Moreover, the part from which the relationship and ratio of a mutual dimension differ also in between drawings may be contained.

  FIG. 1 is a developed plan view of an absorbent article 1 according to an embodiment. FIG. 2 is a cross-sectional view taken along line AA in FIG. The developed plan view shown in FIG. 1 is a diagram of a developed state in which the wing 4 of the absorbent article is developed (not folded). As the absorbent article 1, an arbitrary absorbent article such as a panty liner (orimono sheet), a sanitary napkin or an incontinence pad is assumed. In the present embodiment, a case where a sanitary napkin is used as the absorbent article 1 will be described. The sanitary napkin of the present embodiment is a daytime sanitary napkin, but may be a night sanitary napkin.

  The absorbent article 1 has a front-rear direction L, a width direction W orthogonal to the front-rear direction L, and a thickness direction T. The thickness direction T has a skin facing surface side T1 and a non-skin facing surface side T2 which is the opposite side. The front-rear direction is a direction along the longitudinal direction of the absorbent article. The width direction is a direction along a line connecting the centers of the pair of wings in the front-rear direction.

  The absorbent article 1 includes an absorbent body 30, a skin surface sheet 10 positioned on the skin facing surface side with respect to the absorbent body 30, and a non-skin surface sheet 20 positioned on the non-skin facing surface side with respect to the absorbent body 30. At least.

  The skin sheet 10 includes a top sheet 11 and a side sheet 12. The top sheet 11 covers the skin facing surface side of the absorbent body 30. The side sheet 12 covers the outer edge of the top sheet 11 and extends outward in the width direction from the top sheet 11. The skin sheet 10 can use what is normally used for an absorptive article, for example, can use the sheet | seat material containing a fiber, or an apertured film. Nonwoven fabric and paper can be used for the sheet material containing fibers.

  The non-skin surface sheet 20 is a liquid-impermeable sheet. The non-skin surface sheet 20 covers at least the non-skin facing surface side of the absorber 30. The non-skin surface sheet 20 can use what is normally used for an absorbent article, for example, a non-breathable or breathable film, a nonwoven fabric, etc. can be used.

  The absorber 30 has an absorbent core having an absorbent material such as pulp and SAP, and a core wrap that covers the absorbent core. As the absorber, those normally used for absorbent articles can be used. For example, the absorbent core can use hydrophilic fibers, a polymeric water-absorbing polymer, or a combination thereof. For example, a tissue or a nonwoven fabric can be used for the core wrap.

  The absorbent article 1 has a main body 2 and a wing 4. The main body 2 is located in the center in the width direction W of the absorbent article 1 and extends in the front-rear direction L. The wing 4 extends outward in the width direction W from the outer edge 2E of the main body 2.

  The main body 2 includes a top sheet 11, a side sheet 12, a non-skin surface sheet 20, and an absorber 30. The wing 4 includes a side sheet 12 and a non-skin surface sheet 20. The center 4LC in the front-rear direction of the wing 4 is located within the range in the front-rear direction of the excretion opening facing area that is disposed to face the excretion opening of the wearer. The wing 4 is configured to be able to be folded back to the non-skin surface sheet 20 side, and is folded to the non-skin facing surface side of the underwear when worn. The configuration of the wing 4 will be described in detail later.

  As shown in FIG. 2, a non-skin facing surface of the non-skin surface sheet 20 is provided with a joint for stopping the absorbent article on the underwear S. The joint portion includes a main body joint portion 60 disposed in the main body portion 2 and wing joint portions 61, 62, 63, 64 disposed in the wing 4. These joints may be constituted by an adhesive, or may be configured to function as a hook and a loop of a locking system.

(3) Wing Configuration The wing 4 includes a first wing 41 and a second wing 42. The first wing 41 and the second wing 42 are overlapped with each other while being attached to the underwear S. Therefore, the length in the width direction of the first wing 41 (the length from the base end portion 41BE of the first wing 41 to the outer edge of the first wing 41) and the length in the width direction of the second wing 42 are matched. The total length may be longer than the distance between the base end of the first wing and the base end of the second wing 42, and the distance between the base end of the first wing and the base end of the second wing 42. It is preferable that it is 1.2 times or more. More preferably, the first outer wing joint portion 61 is provided at a position overlapping the second wing 42 when the absorbent article is attached to the underwear, and the second outer wing joint portion 62 is the absorbent article. Is provided at a position overlapping with the first wing 41 in a mounted state in the underwear.

  In the present specification, the base end portion of the wing is a portion located on the innermost side in the width direction of the wing and is a portion that intersects the main body portion 2. When the wing is folded back to the non-skin facing surface side of the underwear, it is folded at the base end of the wing.

  The first wing 41 includes a first outer wing joint portion 61 as a wing joint portion, a first inner wing joint portion 63 as a wing joint portion, and a tear guide portion 80 extending in the front-rear direction L. The first outer wing joint 61 is located outside the tear guide 80 in the width direction W. The first inner wing joint 63 is located on the inner side of the tear guide 80 in the width direction W.

In such an absorbent article, even if the side part in the width direction W of the first wing 41 is unintentionally separated through the tear guiding part 80 before use, the remaining first wing remains on the main body part 2 side. The first inner wing joint 63 exists in the portion. Therefore, the first inner wing joint 63 can be attached to the underwear. Therefore, even if the side part of the width direction W of the 1st wing 41 is torn unintentionally via the tear induction | guidance | derivation part 80, the user can attach the absorbent article 1 to underwear and can use it.
In the first mounting state and the second mounting state, the tear guiding portion 80 is sandwiched between the first inner wing bonding portion 63 and the first outer wing bonding portion 61. Therefore, it is suppressed that the area | region of the tear induction | guidance | derivation part 80 of the 1st wing 41 floats from underwear during wear of an absorbent article. Thereby, it can suppress that the area | region of the tear induction | guidance | derivation part 80 of the 1st wing 41 rubs against outers, such as pants. As a result, it is possible to prevent the first wing from being unintentionally torn through the tear guiding portion 80 during wearing of the absorbent article.

  The width of the first inner wing joint portion 63 in the width direction W is preferably narrower than the width of the first outer wing joint portion 61 in the width direction W. Thereby, the bonding force of the first inner wing bonding portion 63 is smaller than the bonding force of the first outer wing bonding portion 61. Therefore, when the user tries to remove the absorbent article from the undergarment, the first inner wing joint 63 is first detached from the undergarment due to the pulling force of the absorbent article. If the 1st inner side wing joint part 63 remove | deviates from underwear, the force which pulls an absorbent article will become easy to be applied to the tearing induction part 80 of the 1st wing 41, As a result, the tearing induction part 80 will fracture | rupture. Thus, by narrowing the width of the first inner wing joint 63, the used absorbent article can be easily removed from the underwear.

  Further, the length of the first inner wing joint portion 63 in the front-rear direction L is preferably longer than the length of the first outer wing joint portion 61 in the front-rear direction L. When removing the absorbent article from the underwear, for example, the user holds the edge of the main body 2 and pulls the end of the main body 2 away from the underwear (FIGS. 7A and 7B). reference). When a part of the main body 2 is separated from the underwear, the pair of wings 41 and 42 are pulled to the main body 2 side, and a force F1 pulled to the outer side W in the width direction is applied to the wing (FIGS. 7B and 7D). reference). Since the user pulls one of the front end edge and the rear end edge of the main body 2, the force F <b> 1 is biased to one of the front side or the rear side of the first wing 41. At this time, in a state where both the first inner wing joint portion 63 and the first outer wing joint portion 61 are joined to the undergarment, a state where a force is hardly applied to the tear guiding portion 80 is maintained. When the user further pulls the edge of the main body 2 and the first inner wing joint 63 comes off the underwear, the force F1 causes the front edge and the rear edge of the first inner wing joint 63 to Is instantaneously pulled up toward the main body 2. On the other hand, since the first wing 41 and the second wing 42 are firmly joined to each other at the first outer wing joint 61, the region of the first outer wing joint 61 resists the force F1. Attempts to stay at a stationary position with respect to the underwear S. As a result, at the moment when the first inner wing joint 63 is detached from the underwear, a force that is slightly twisted is applied to the region of the tear guiding portion 80. In particular, when the length of the first inner wing joint portion 63 in the front-rear direction L is longer than the length of the first outer wing joint portion 61 in the front-rear direction L, the force that deforms the first wing 41 to be twisted is It tends to be applied near the end portion of the tear guiding portion 80 in the direction L. Therefore, at the moment when the first inner wing joint 63 is detached from the underwear, the vicinity of the end portion of the tear guiding portion 80 is easily broken.

  The outer side edge in the width direction W of the first inner wing joint part 63 extends in parallel with the tear guiding part 80, and the inner side edge in the width direction W of the first outer wing joint part 61 is a tear. It is preferable to extend in parallel with the guide portion 80. Thereby, in the first wearing state (FIGS. 3 and 4) and the second wearing state (FIGS. 5 and 6), the region of the tear guiding portion 80 is adjacent to the underwear in a uniform state. If the first inner wing joint portion 63 and the first outer wing joint portion 61 and the tear guiding portion 80 are not parallel to each other, a part of the region of the tear guiding portion 80 may easily float from the underwear. is there. In this case, there is a possibility that a part of the tear guiding portion 80 is unintentionally broken during wearing of the absorbent article. If a part of the tear guiding portion 80 is unintentionally broken, the entire tear guiding portion 80 may be unintentionally broken with the broken portion as a starting point. In the present embodiment, since the first inner wing joint portion 63 and the first outer wing joint portion 61 and the tear guide portion 80 are parallel to each other, the possibility that the tear guide portion 80 breaks unintentionally is reduced. be able to.

  Preferably, in the unfolded state of the first wing 41 and the second wing 42, the distance D13 between the base end portion 41BE of the first wing 41 and the base end portion 42BE of the second wing 42 is the first inner wing joint portion. 63 is longer than the sum of the distance D16 between the outer edge of 63 and the proximal end of the first wing 41 and the distance D17 between the outer edge of the second wing 42 and the proximal end of the second wing. . Thereby, in the 2nd wearing state (Drawing 5 and Drawing 6), the 1st inner side wing joint part 63 is joined to underwear, without overlapping with the 2nd wing 42. Since the first inner wing joint portion 63 is not joined to the second wing 42, the first wing 41 and the second wing 42 are separated from each other when the user tears the tear guiding portion 80. Thereby, the user can remove an absorbent article from underwear easily also in a 2nd mounting state. In addition, since the first inner wing joint 63 is joined to the undergarment, the absorbent article in use can be more difficult to shift.

  The second wing 42 has a second outer wing joint 62 as a wing joint and a second inner wing joint 64 as a wing joint. In the present embodiment, the second wing 42 does not have a tear guiding portion. That is, the tear guiding portion 80 is provided only in the first wing 41. Instead, the second wing 42 may have a tear guiding portion.

  In the present embodiment, the second wing 42 has a second outer wing joint 62 and a second inner wing joint 64. However, the present invention is not limited to this, and the second wing 42 may have only one of the second outer wing joint 62 and the second inner wing joint 64. The second wing 42 may not have both the second outer wing joint 62 and the second inner wing joint 64.

  The tear guiding portion 80 is configured so that the wearer can easily tear the wing. Specifically, the tear guiding portion 80 is configured by a perforation, a concave portion that is recessed backward from the front edge of the wing, a fragile portion in which the strength of the material is lower than the surroundings, or a combination thereof. The perforation has an opening penetrating the side sheet 12 and the non-skin sheet 20 constituting the first wing 41. The “front edge” of the wing is an outer edge 41FE that extends outward in the width direction from the base end portion 41BE on the front side of the wing among the outer edges of the wing. Moreover, a weak part is providing the opening in the skin sheet | seat 10 without providing the opening in the part which reduced the fabric weight of the said material by expanding the material which comprises the 1st wing 41, and the non-skin sheet | seat sheet 20 The part which made the intensity | strength low compared with the circumference | surroundings and the part which reduced the intensity | strength of material with heat and pressure by embossing can be illustrated.

  Since the tear guiding portion 80 extends along the front-rear direction L, the tearing portion that is torn through the tear guiding portion 80 extends in the front-rear direction L. The front end edge of the tear guiding portion 80 may coincide with the front end edge of the first wing 41. In the configuration in which the distance between the front end edge of the front tear guiding portion 80 and the front end edge of the first wing 41 is 4 mm or less, the front end edge of the tear guiding portion 80 and the front end edge of the first wing 41 coincide with each other. The same effect can be obtained and the first wing 41 can be easily separated via the tear guiding portion 80. In addition, the tear guiding portion 80 may extend from one end to the other end in the front-rear direction L of the first wing 41.

  The tear guiding portion 80 is disposed on the inner side in the width direction than the first outer wing joint portion 61 in the developed state of the first wing shown in FIGS. 1 and 2. The distance D11 between the first outer wing joint portion 61 and the tear guiding portion 80 may be shorter than the distance D12 between the base end portion 41BE of the first wing 41 and the tear guiding portion 80. In this case, when the wearer pulls the main body including the absorber in a direction away from the underwear, a tearing force is applied between the main body and the wing, and in the first wing, a force is applied near the first wing joint 61. Easy to take. Since the tear guiding portion 80 is located closer to the first wing joint portion 61 than the base end portion of the first wing 41, the tearing force is efficiently applied to the tear guiding portion 80, and the two first wings 41 can be easily formed. Can be separated. Further, the wearer traces the base end of the wing at the time of wearing, and puts the wing on the underwear. Since the tear guiding portion is relatively away from the base end portion of the wing, it is difficult for the wearer to touch the tear guiding portion during wearing, and the tear guiding portion can be prevented from being unintentionally torn during wearing.

  In the unfolded state of the first wing 41 and the second wing 42, the distance D13 between the base end portion 41BE of the first wing 41 and the base end portion 42BE of the second wing 42 is torn with the base end portion 41BE of the first wing 41. The distance D12 between the guide portion 80 and the distance D14 between the outer edge of the second outer wing joint 62 and the base end portion BE of the second wing 42 may be longer. Since the distance D13 is longer than the total length of the distance D12 and the distance D14, the second outer wing joint 62 and the tear guide 80 are necessarily separated in the width direction in the first mounting state. Since the second outer wing joint 62 and the tear guiding portion 80 do not overlap, the first wing is easily torn through the tear guiding portion 80 and is smoothly separated into two.

  The difference between the distance D13 combined with the distance D12 and the distance D13 may be 3 mm or more. When the distance between the distance D12 and the distance D14 is less than 3 mm and the difference between the distance D13 and the distance D13 is less than 3 mm, when the wing is folded back to the non-skin surface side with the inner side in the width direction as the folding base point, In the first mounting state, the second outer wing joint 62 may overlap the tear guide 80 and the tear guide 80 may be difficult to break.

(4) Attaching Mode and Removing Mode of Absorbent Article FIGS. 3 to 6 show a state where the absorbent article is attached to the underwear. 3 and 4 show a first mounting state in which the first wing 41 is disposed inside the second wing 42 in the thickness direction T and the absorbent article 1 is mounted on the undergarment S. FIG. FIG. 6 shows a second wearing state in which the first wing 41 is disposed outside the second wing 42 in the thickness direction T, and the absorbent article 1 is worn on the underwear. FIG. 7 is a diagram schematically showing the removal mode in the second mounting state.

  As shown in FIGS. 7A and 7B, in a state where the absorbent article 1 is mounted on the underwear S, the main body 2 is joined to the skin facing surface side of the underwear S, and the pair of wings 4 are It is joined to the non-skin facing side of the underwear. More specifically, in the first mounting state, the first wing 41 and the undergarment S are joined via the first outer wing joint 61, and the first wing 41 and the second garment are joined via the second outer wing joint 62. The wing 42 is joined. In the second mounting state, the second wing 42 and the undergarment S are joined via the second outer wing joint 62, and the first wing 41 and the second wing 42 are joined via the first outer wing joint 61. Are joined.

  When removing the absorbent article 1, the wearer generally holds the front end edge of the main body 2 and pulls the front end edge of the main body 2 away from the underwear. Since the pair of wings 4 are bonded to each other on the non-skin facing surface side of the underwear, when the main body 2 is separated from the underwear, the pair of wings 4 is to be maintained while being bonded to the underwear, and is torn between the main body 2 and the wing 4. It takes power. The force applied to the wing 4 tends to act strongly on the front side gripped by the wearer. The first wing 41 is torn through the tear guiding portion 80 (see FIGS. 7C and 7D). When the wearer further pulls the main body 2, the first wing 41 is separated into two along the front-rear direction L as shown in FIGS. 7 (E) and B (F).

  When the first wing 41 is separated into two in the first mounting state, a part of the first wing 41 on the base end side is connected to the main body 2. On the other hand, the side portion of the first wing 41 in the width direction W is connected to the second wing 42 via the second outer wing joint 62. When the wearer further pulls the absorbent article, the first outer wing joint 61 and the undergarment are separated, and the main body joint 60 and the undergarment are separated, and the entire absorbent article is removed from the undergarment.

  Further, when the first wing 41 is separated into two in the second mounting state, a part of the base end portion side of the first wing 41 is connected to the main body portion 2. The side portion of the first wing 41 in the width direction W is connected to the second wing 42 via the first outer wing joint 61. When the wearer further pulls the absorbent article, the second outer wing joint 62 and the undergarment are separated, and the main body joint 60 and the undergarment are separated, and the entire absorbent article is removed from the undergarment.

(5) Modified Example Next, an absorbent article according to a modified example will be described based on FIGS. 8 to 10. In the description of the modification, the same reference numerals are used for the same configurations as those in the above-described embodiment, and the description is omitted.

  FIG. 8 is a plan view of the developed state of the absorbent article 1A according to the first modification. An absorbent article 1A according to Modification 1 has a tear guiding portion 81 formed of a recess. Moreover, the 1st wing 41 of 1 A of absorbent articles which concerns on the modification 1 is sheet | seat joining area | region R1 where the skin sheet 10 and the non-skin surface sheet 20 were joined, the skin sheet 10 and the non-skin sheet 20 Is not joined, and the sheet joining region R1 and the sheet non-joining region R2 extend in the front-rear direction.

  The sheet bonding region R1 is a region that is hatched in FIG. The sheet joining region R1 is a region where the sheets are joined by an adhesive such as HMA, heat welding, or the like.

  The tear guiding portion 81 is a concave portion that is recessed backward from the front end edge of the first wing 41. The tear guiding portion 81 is disposed in the sheet non-bonding region R2. The recessed part should just be comprised so that it may dent toward the back from the front edge of a wing, and the shape is not limited, such as circular arc shape, trapezoid shape, V shape. The length of the recess in the front-rear direction (depth of the recess) may be 1 mm or more and 15 mm or less. When the length of the recess in the front-rear direction is 1 mm or more, the wing tends to tear, and when the length of the recess in the front-rear direction is greater than 15 mm, the wing may be unexpectedly torn.

  The sheet non-bonding region R2 has a lower strength than the sheet bonding region R1, and is easily torn by the tear guiding portion 81. Since the tear guiding portion 81 is disposed in the sheet non-bonding region R2 having a relatively low strength, the first wing is torn in the sheet non-bonding region R2. Since the sheet bonding region R1 and the sheet non-bonding region R2 extend in the front-rear direction, the tearing portion easily extends in the front-rear direction.

  FIG. 9 is a plan view of the developed state of the absorbent article 1B according to the second modification. The absorbent article 1B according to Modification 2 includes a tear guiding portion 82 including a perforation and a recess. The tear guiding portion 82 is provided continuously from the front end edge 41FE to the rear end edge 41RE of the first wing 41. Moreover, the length of the front-back direction of the 1st wing 41 of the absorbent article 1B which concerns on the modification 2 and the length of the front-back direction of the 2nd wing 42 are short as it goes to the outer edge of a deployment state.

  The first wing 41 has a convex constriction 70 toward the center 4LC in the front-rear direction L. The tear guiding portion 82 is provided in the region of the constriction 70. The first wing 41 has a convex region 72 that is convex outward from the center in the front-rear direction L of the first wing 41 on the inner side in the width direction than the region of the constriction 70. The region of the constriction 70 is a region where the outline 41FE of the first wing 41 is convex toward the center 4LC in the front-rear direction L. The boundary on the inner side in the width direction W of the region of the constriction 70 may be an inflection point on the outline 41FE of the first wing 41. It should be noted that even when the tear guiding portion 80 is provided at the boundary position of the constricted 70 region, the tear guiding portion 80 is provided in the constricted 70 region. In the case of the tear guiding portion 82 formed of a concave portion as in the present embodiment, the outer shape of the wing on both sides in the width direction or one side in the width direction of the tear guiding portion 82 is a region having a constriction 70 (convex shape at the center 4LC in the front and rear direction of the wing). It is assumed that the tear guiding portion 82 is provided in the constricted region 70.

  The first wing 41 has a convex region 72 that is convex outward from the center in the front-rear direction L of the first wing 41 on the inner side in the width direction than the region of the constriction 70. The boundary on the outer side in the width direction W of the convex region 72 having a convex shape may be an inflection point on the outline 41FE of the first wing 41.

  The outer edge of the region 70 in the width direction W in the width direction W may reach the outer side of the first wing joint portion 61 on the inner side in the width direction W, and the outer side of the first wing joint portion 61 in the width direction W. It may have reached the outside of the edge of. Thereby, when removing an absorbent article from underwear, the force which concentrates on the 1st wing junction part 61 can be easily applied to the tearing induction part 80. FIG.

  The tear guiding portion 82 is configured by a recess located at the front end edge 41FE and the rear end edge 41RE of the first wing 41 and a perforation that continuously extends between the recess and the recess.

  When removing an absorbent article from underwear, a user grasps an end edge of main part 2 and pulls an end of main part 2 away from underwear, for example. When the main body 2 is separated from the underwear, the pair of wings 41 and 42 are pulled toward the main body 2. A convex region 72 having a convex shape is provided on the inner side in the width direction from the region of the constriction 70 toward the outer side from the center in the front-rear direction L of the first wing 41. When the user pulls toward the main body 2, the convex region 72 swelled in the front-rear direction L pulls a portion on the outer side in the width direction than the convex region 72, that is, the region of the constriction 70 inward in the width direction. On the other hand, the wing overlap portion where the wings join each other in the width direction outside of the wings 41 and 42 resists the force pulled from the convex region 72 and stays on the non-skin surface side of the underwear. Power is applied to the overlapping part. The force applied to the wings 41 and 42 tends to concentrate on the position of the constriction 70 from the convex region 72 swelled in the front-rear direction L. Since the tear guiding portion 80 exists at the position of the constriction 70, the tear guiding portion 80 is easily torn by the force with which the wings 41 and 42 are pulled.

  In the second modification, the tear guiding portion 82 is provided continuously from the front end edge to the rear end edge of the first wing 41. In an absorbent article having the same front and rear shapes, such as a daytime napkin, the wearer may wear the front and back in reverse. Since the tear guiding portion 82 is provided from the front end edge to the rear end edge of the first wing 41, the tear guiding portion 82 is arranged on the front side of the wearer even when the first wing 41 is worn in the reverse direction. The first wing 41 can be broken through the guide portion 82.

  FIG. 10 is a plan view of the developed state of the absorbent article 1C according to Modification 3. In the absorbent article 1 </ b> C according to Modification Example 3, the first wing 41 is provided with the tear guiding portion 83, and the second wing 42 is also provided with the tear guiding portion 84. The tear guiding portion 84 extends from the rear end edge 42RE of the second wing 42 in the front-rear direction. Similar to the tear guiding portion 83, the tear guiding portion 84 can be configured by perforations, concave portions, fragile portions, and combinations thereof.

  Even if the second wing 42 has the tear guiding portion 84, the tear guiding portion 80 of the first wing 41 or the tear guiding portion 84 of the second wing 42 is worn even when the second wing 42 is mounted reversely. It is arranged in front of the person. Therefore, even if it is a case where it is mounted reversely in the front-rear direction, the wing 4 is divided by peeling the main body 2 from the underwear, so that the work of removing the absorbent article 1 can be easily performed.

  Depending on a wearer, when removing an absorbent article after use, the rear side of the main body 2 may be gripped and the main body may be pulled away from the undergarment. Thus, even if it is a case where the main-body part 2 is pulled from the rear side, the 2nd wing 42 isolate | separates into two. Therefore, even if the removal work is performed in the reverse direction, the main body 2 and the pair of wings 4 can be removed together without dropping a part of the wing, and the removal work of the absorbent article can be performed cleanly. . That is, even if the wearer tries to remove the absorbent article from the front side of the main body part 2 or tries to remove the absorbent article from the rear side of the main body part 2, at least one of the first wing 41 and the second wing 42 is required. One is divided.
