[0047] The absorbent article 1 may have a pair of wings 40, which extend outward from the absorbent body 30 in the width direction W and are folded back toward the non-skin side of the underwear when worn. The wings 40 are provided as a pair at intervals in the width direction W. The wings 40 may be arranged in the central area S1, the front end edge 40F of the wings 40 constitutes the front end edge of the central area S1, and the rear end edge 40R of the wings 40 constitutes the rear end edge of the central area S1. The side sheets 12 as the surface sheets 10 and the back sheet 20 may be arranged on the wings 40. The wings 40 may be folded back toward the skin side T1 of the absorbent article 1 before use. The absorbent article 1 may have a wing peeling sheet (not shown) which covers the wing fixing portion 62 provided on the non-skin surface of each wing 40 when the pair of wings 40 are folded back. The wing peeling sheet may be arranged across the wing fixing portion 62 carried by each wing 40. In addition, in a modified example, the absorbent article 1 may not have the wing 40 .

[0048] The absorbent article 1 may not be linearly symmetrical when the axis of symmetry is the article width center 1CW that passes through the center in the width direction W of the absorbent article 1 and extends in the front-to-back direction L. That is, the absorbent article 1 may be left-right asymmetrical when viewed from above. In addition, the absorbent article 1 may not be linearly symmetrical when the axis of symmetry is the article front-to-back center 2CL that passes through the center in the front-to-back direction L of the absorbent article 1 and extends in the width direction W. That is, the absorbent article 1 may be front-to-back asymmetrical when viewed from above. In addition, the article front-to-back center 2CL of the absorbent article 1 of the present embodiment may be located at a position forward of the center line that passes through the center in the front-to-back direction L of the wing 40. For the wing 40, it may not be linearly symmetrical when the axis of symmetry is the article front-to-back center 2CL.

[0049] Next, the structure for hygienically grabbing the convex portion 50 and removing the absorbent article 1 in the absorbent article 1 thus constructed will be described in detail. The convex portion 50 is provided at the outer end portion in the front-back direction L of the absorbent article 1, and the convex portion 50 extends outward when the absorbent article 1 is viewed from above. Since the absorbent article 1 is provided with the convex portion 50, the wearer can grab the convex portion 50 and remove the absorbent article 1 from the underwear after using the absorbent article 1. The convex portion 50 is a portion protruding toward the outside of the absorbent article 1. The boundary BL between the convex portion 50 and the portion other than the convex portion may be an imaginary line extending along the outer line of the region of the absorbent article located around the convex portion 50, or may be the outer line of the region where the convex portion 50 is not provided in the embodiment in which the convex portion 50 is provided only on the left and right sides as in the present embodiment.

[0050] A non-fixed area is provided on the non-skin side T2 of the convex piece 50, and no fixing part 60 is provided in the non-fixed area. Figure 2 In the top view of the absorbent article 1 as viewed from the non-skin side T2, there is no region where the fixing portion 60 is arranged. Since the non-fixed region is provided in the convex portion 50, the wearer can grasp the region where the fixing portion is not provided when grasping the convex portion 50 to remove the absorbent article 1, thereby preventing the wearer's fingers from touching the fixing portion 60 and preventing the wearer from feeling uncomfortable due to grasping the fixing portion 60.

[0051] The convex portion 50 is separated from the article width center 1CW. That is, the inner edge 50I of the convex portion 50 is separated from the article width center 1CW. The excretion port is usually arranged across the article width center 1CW, and the body fluid is discharged toward the article width center 1CW. In the case of a large amount of body fluid, there is a case where the body fluid spreads outward along the article width center 1CW in the front-rear direction L and reaches the outer edge of the absorbent article 1. However, since the convex portion 50 is separated from the article width center 1CW, even if the body fluid reaches the outer edge of the absorbent article 1 along the article width center 1CW, the body fluid will not adhere to the convex portion 50, and the convex portion 50 can be kept more hygienic. Therefore, after use, the absorbent article 1 can be removed by holding the convex portion 50 hygienically. In particular, in the urine collecting pad, the urine outlet is located at a position closer to the front side than the vaginal opening, and the body fluid is easily guided to the front end of the absorbent article. However, since the convex piece 50 is separated from the article width center 1CW, even when the body fluid is guided to the front end of the absorbent article, it is possible to suppress the body fluid from adhering to the convex piece 50 provided at the front end of the absorbent article. The distance between the inner edge 50I of the convex piece 50 and the article width center 1CW is not limited, but from the viewpoint of suppressing the adhesion of body fluid, it can be 10 mm or more, preferably 20 mm or more.

[0052] At least part of the convex piece 50 may be arranged at a position outside the width direction W of the outer edge 61E of the main body fixing part 61. That is, the convex piece 50 and the outer edge 50E may be located outside the width direction W of the outer edge 61E of the main body fixing part 61. According to this structure, the force of pulling the convex piece 50 can be applied to the outer edge 61E of the main body fixing part 61, and the main body fixing part 61 can be smoothly peeled off from the underwear. In addition, as in the present embodiment, the outer edge of the main body fixing part 61 composed of a plurality of adhesive parts arranged in the width direction W is the outer edge of the adhesive part located at the outermost position.

[0053] The outer edge 50E of the protruding piece 50 may be located outside the outer edge 61E of the main body fixing portion 61 in the width direction W, and the inner edge 50I of the protruding piece 50 may be located inside the outer edge 61E of the main body fixing portion 61 in the width direction W. Figure 2As shown in FIG. 1 , the convex piece 50 may be arranged on an extension line 61EL extending from the outer edge 61E of the main body fixing portion 61 in the front-back direction L. According to this embodiment, the convex piece 50 straddles the outer edge 61E of the main body fixing portion 61 in the width direction W, so that it is easier to apply a force to pull the convex piece 50 to the outer edge 61E of the main body fixing portion 61, and the main body fixing portion 61 can be smoothly peeled off from the underwear, thereby smoothly removing the entire absorbent article 1. In addition, the distance between the outer edge 61E of the main body fixing portion 61 and the inner edge 50I of the convex piece 50 in the width direction W can be shorter than the distance between the outer edge 61E of the main body fixing portion 61 and the outer edge 50E of the convex piece 50 in the width direction W.

[0054] The front end edge 50F of the convex piece 50 may be located at a position further outward in the width direction W than the outer side edge 61E of the main body fixing part 61. The front end edge 50F of the convex piece 50 is a portion that is most convex to the front side of the convex piece 50 and is easily grasped by the wearer. According to this structure, by causing the wearer to grasp the portion including the front end of the convex piece 50, a force that pulls the convex piece 50 can be applied to the outer side edge 61E of the main body fixing part 61. The distance between the front end edge 50F of the convex piece and the inner side edge 50I of the convex piece 50 in the width direction W may be shorter than the distance between the front end edge 50F of the convex piece 50 and the outer side edge 50E of the convex piece 50 in the width direction W.

[0055] like Figure 2 As shown, at least a part of the convex piece 50 may be arranged on the absorbent body extension line 30EL, which passes through the outer edge 30E in the width direction W of the absorbent body 30 and extends in the front-back direction L. That is, the outer edge 50E of the convex piece 50 may be located outside the outer edge 30E of the absorbent body 30 in the width direction W, and the inner edge 50I of the convex piece 50 may be located inside the outer edge 30E of the absorbent body 30 in the width direction W. Since the convex piece 50 is arranged on the absorbent body extension line 30EL, it is easier to apply the force for gripping the convex piece 50 to remove it to the outer edge 30E of the absorbent body 30, and the absorbent body 30 with relatively high rigidity can be pulled to smoothly remove the entire absorbent article. In addition, at least a portion of the main body fixing portion 61 may be arranged at a position that is more inward than the outer edge 30E of the absorber 30 in the width direction W. Preferably, the entire area of ​​the main body fixing portion 61 may be arranged at a position that is more inward than the outer edge 30E of the absorber 30 in the width direction W. According to this structure, the convex piece portion 50 can be gripped and a removal force can be applied to the outer edge of the absorber 30, and the entire main body fixing portion 61 can be smoothly peeled off by using this force.

[0056] The shape of the outer end of the absorbent body 30 in the front-back direction L may be a curved shape (e.g., a convex shape), and in particular, the end of the absorbent body 30 on the side (the front side in this embodiment) where the convex piece 50 is arranged may be a curved shape. According to this structure, compared with a structure in which the outer end of the absorbent body 30 is linear, it is less likely to form a point where the rigidity changes locally, and the absorbent article 1 can be easily and smoothly peeled off even with a weak force. The front end edge 30F of the absorbent body 30 and the front end edge 50F of the convex piece 50 may be offset in the width direction W. In addition, in the form of providing the convex piece at the rear end of the absorbent article 1, the rear end edge of the absorbent body 30 and the rear end edge of the convex piece may be offset in the width direction.

[0057] At least a surface sheet 10 and a back sheet 20 may be arranged in the convex sheet portion 50. The surface sheet 10 and the back sheet 20 arranged to sandwich the absorbent body 30 are provided in the convex sheet portion 50, so that by holding and pulling the convex sheet portion 50, the absorbent body 30 sandwiched between the two sheets can be pulled together with the surface sheet 10 and the back sheet 20, thereby smoothly removing the entire absorbent article 1. The convex sheet portion 50 of this embodiment is configured with a side sheet 12 as the surface sheet 10, and a back sheet 20.

[0058] The non-fixed area may be provided at least partially on the convex portion 50. However, it is preferred that the non-fixed area be provided on the entire area of ​​the convex portion 50. According to this embodiment, no matter where the wearer grasps the convex portion 50, the fixing portion 60 will not be grasped. Therefore, the discomfort caused by grasping the fixing portion 60 can be suppressed, and the absorbent article 1 after use can be disposed of hygienically.

[0059] The convex piece 50 may be disposed only on one side in the width direction W relative to the width center 1CW of the article. Since the convex piece 50 is disposed only on one side, the convex piece 50 is more conspicuous and easier to identify than a structure in which the convex piece 50 is disposed on both sides, and the convex piece 50 can be used to hygienically dispose of the absorbent article 1 during the removal operation after use. In addition, since the convex piece 50 is disposed only on one side in the width direction W relative to the width center 1CW of the article, the absorbent article 1 becomes left-right asymmetric. The presence of the convex piece 50 allows the orientation and arrangement position of the absorbent article 1 to be grasped, and the installation operation can be easily performed.

[0060] Preferably, the convex piece 50 can be arranged at the front end of the absorbent article 1. The front end of the absorbent article 1 is a portion that is easily visually recognized by the wearer and easy for the wearer to grasp when discarding. Therefore, by providing the convex piece 50 at the front end of the absorbent article 1, it is easier for the wearer to use the convex piece 50 when discarding. More preferably, the convex piece 50 can be arranged in a plan view ( Figure 1The applicant has conducted an in-depth investigation and found that the wearer often grabs the front end of the absorbent article 1 with the right hand when discarding it. By providing the convex piece 50 at the front end of the right side of the absorbent article 1, the wearer can easily and smoothly grab the convex piece 50.

[0061] The convex piece 50 of the embodiment is arranged only on one side of the front end of the absorbent article 1 with respect to the article width center 1CW, and is not provided at the rear end of the absorbent article 1. However, in a modified example, the convex piece 50 may be arranged on both sides of the front end of the absorbent article 1 with respect to the article width center 1CW, may be arranged at both the front end and the rear end of the absorbent article 1, or may be arranged only at the rear end of the absorbent article 1.

[0062] At least a portion of the leakage-proof gathers 70 may be provided at the convex piece 50. The leakage-proof gathers 70 of the present embodiment are composed of a portion formed by folding the side sheet 12 and a leakage-proof elastic member 74, and the portion formed by folding the side sheet 12 is provided at the convex piece 50. According to the present embodiment, the leakage-proof gathers 70 are used to increase the rigidity of the convex piece 50, and the entire absorbent article 1 can be smoothly removed when the convex piece 50 is grasped and pulled. In addition, when the convex piece 50 is pulled, the absorbent article 1 can be pulled in the front-rear direction L by the contraction of the leakage-proof elastic member 74, so that the entire absorbent article 1 can be more smoothly peeled off. For the area on the outside in the front-rear direction L than the front-rear base point 72 of the leakage-proof gathers 70, the side sheet 12 does not stand up, and the side sheets 12 are fixed to each other. At least a portion of the fixed portion may be provided at the convex piece 50. According to this structure, the rigidity of the fin portion 50 is further increased by the leakage-proof gathers 70 , and the entire absorbent article 1 can be removed more smoothly by grasping and pulling the fin portion 50 .

[0063] The contraction portion 71 of the leak-proof gathers 70 can be provided separately from the convex portion. That is, the boundary BL of the convex portion 50 can be separated from the contraction portion 71 and can be arranged at a position further outside in the front-to-back direction L than the contraction portion 71. According to this embodiment, the convex portion 50 can be prevented from contracting due to the contraction of the contraction portion 71, and the convex portion 50 can be maintained in a state where it is easy for the wearer to grasp. The contraction portion 71 is composed of an area that stands up toward the wearer's side by utilizing the contraction of the leak-proof elastic member 74. Figure 1, the range of the contraction part 71 in the front-to-back direction is shown. In a mode in which the elastic leakage-proof member 74 that can be stretched and fixed extends to the outside in the front-to-back direction L across the contraction part 71, the front-to-back base point 72 constitutes the outer edge in the front-to-back direction of the contraction part 71, and in a mode in which the elastic leakage-proof member 74 that can be stretched and fixed is only arranged at a position closer to the inside in the front-to-back direction L than the contraction part 71, the outer edge in the front-to-back direction L of the portion of the elastic leakage-proof member 74 that can be stretched and fixed constitutes the outer edge in the front-to-back direction of the contraction part 71.

[0064] At least part of the sheet pressing portion 86 is provided on the convex portion 50. According to this structure, the sheet pressing portion 86 can be used to increase the rigidity of the convex portion 50, so that the convex portion 50 can be easily grasped and the entire absorbent article 1 can be easily removed by means of the convex portion 50. Figure 4 As shown, the sheet pressing portion 86 can be arranged across the boundary BL between the convex portion 50 and the area outside the convex portion. According to this structure, when the convex portion 50 is grasped and pulled, it is easy to transfer the force applied to the convex portion 50 to the area outside the convex portion, so that the entire absorbent article 1 can be peeled off more smoothly.

[0065] The convex portion 50 may be provided at one of the front end and the rear end of the absorbent article 1, and the other of the front end and the rear end of the absorbent article 1 may be provided with a recessed portion 55 that is recessed inward when the absorbent article 1 is viewed from above. According to this structure, the absorbent article 1 becomes asymmetrical in the front and rear. Therefore, the convex portion 50 is more conspicuous, and the wearer can easily identify the convex portion 50, and the convex portion 50 can be used to hygienically dispose of the absorbent article during the removal operation after use. In addition, the orientation and configuration position of the absorbent article can be grasped by the presence of the convex portion 50 and the recessed portion 55, and the installation operation can be easily performed. In this embodiment, the convex portion 50 is provided at the front end of the absorbent article, and the recessed portion 55 is provided at the rear end of the absorbent article.

[0066] The recessed portion 55 may be provided on an extension line extending from the convex piece 50 in the front-to-back direction L. When the absorbent articles 1 are continuously manufactured in a state where the absorbent articles 1 are arranged in the front-to-back direction L, the part of the convex shape of the convex piece 50 that is convex outward is adjacent to the inward concave shape of the recessed portion 55, which can reduce waste materials (so-called scraps).

[0067] The main body squeezing portion 80 can also be used to make the presence and position of the convex piece 50 conspicuous. In detail, the front squeezing portion 84 is a design imitating the number 0 (zero), and is a design indicating a partial notch thereof, with the notch portion being on top. By providing the notch portion, the wearer's attention can be drawn, and the presence of the convex piece 50 arranged near the notch portion can be made conspicuous. In addition, the orientation of the number can be used to indicate the orientation of the front-to-back direction L of the absorbent article 1. In addition, the rear squeezing portion 85 is a design imitating cotton, and the orientation of the cotton can be used to indicate the front-to-back direction L of the absorbent article 1. In addition, the rear squeezing portion 85 indicates cotton, thereby indicating the material of the absorbent article 1 when it contains cotton fibers. In the case where the absorbent article 1 has a cotton-like touch, its touch can be indicated.

[0068] At least a portion of the sheet material constituting the absorbent article 1 may be provided with a welded portion formed by welding fibers to each other. In the present embodiment, the first nonwoven fabric 31 and the second nonwoven fabric 32 are formed of hot air nonwoven fabrics having a welded portion. According to this structure, when the convex piece 50 is grasped and pulled, the force applied to a part of the area is easily transferred in the planar direction, so that the entire absorbent article 1 can be easily and smoothly peeled off.

[0069] The outer side portion in the width direction W of the wing 40 may have a convex portion 41 that bulges outward in the width direction W. The vertex 42 of the convex portion 41 may be arranged at a position more rearward than the wing center 40CL. In addition, the wing 40 of the present embodiment is a shape in which the wing 40 as a whole bulges outward in the width direction W, the wing 40 as a whole constitutes the convex portion 41, and the vertex 42 of the convex portion 41 is dot-shaped. The length of the wing 40 in the front-to-back direction L gradually shortens from the inner side edge (root) of the wing 40 toward the outer side in the width direction W. The vertex 42 of the convex portion 41 is arranged at a position more rearward than the wing center 40CL. Therefore, when the convex portion provided at the front end portion of the absorbent article 1 is grasped and the absorbent article 1 is peeled off from the front side to the back side, it is easy to gradually peel off the absorbent article, and it is easy to peel off the entire absorbent article 1 more smoothly.

[0070] like Figure 2 As shown, if the line connecting the front edge 40F of the wing 40 and the vertex 42 of the convex portion 41 is set as the first imaginary line FL1, the line connecting the rear edge 40R of the wing 40 and the vertex 42 of the convex portion 41 is set as the second imaginary line FL2, and the line connecting the front edge 40F and the rear edge 40R of the wing 40 is set as the third imaginary line FL3, then the angle α formed by the third imaginary line FL3 and the first imaginary line FL1 can be smaller than the angle β formed by the third imaginary line FL3 and the second imaginary line FL2. According to this structure, the wing 40 can be easily folded or rolled from the front edge 40F side of the wing 40 toward the rear edge 40R side, and the installation operation and the disposal operation can be smoothly performed.
