(1) Outline of Embodiment At least the following matters will be clarified by the description of this specification and the accompanying drawings.

The absorbent article according to one aspect is between the longitudinal direction, the width direction orthogonal to the longitudinal direction, the front waist circumference area, the rear waist circumference area, and the front waist circumference area and the rear waist circumference area. The inseam region, at least the absorber arranged in the inseam region, a pair of flap portions extending outward from the absorber in the width direction in the rear waist circumference region, and the pair of flap portions are provided. , A fastening tape having a hook that engages with the front waist circumference area. The fastening tape has an unfoldable foldable portion that is folded into at least three layers, and the flap portion is folded from a longitudinal fold line along the longitudinal direction in a folded state of the absorbent article. In a state where the pair of flap portions are folded starting from the longitudinal folding line, the fastening tapes provided on the pair of flap portions overlap each other.

Since the pair of fastening tapes overlap each other with the flap portion folded, the thickness of the portion where the fastening tapes overlap each other increases. As a result, at least one flap portion (flap portion located on the upper side) is likely to float upward, and a gap is likely to be formed under the one flap portion. Therefore, the assistant or the user can easily insert the finger due to this gap and can easily deploy the flap portion.

According to a preferred aspect, the free end of the fastening tape extends outward of the flap in the width direction in a state where the pair of flaps are folded starting from the longitudinal fold line.

Since the free end of the fastening tape protrudes to the outside of the flap, the distance from the free end of the flap to the longitudinal fold line can be made relatively long. As a result, the free end of the fastening tape, which is the bending starting point of the flap portion, is moved away from the longitudinal fold line, so that a gap is likely to be formed on the lower side of the flap near the longitudinal fold line. Therefore, the assistant or the user can easily insert the finger due to this gap, and can more easily deploy the flap portion.

According to a preferred embodiment, the folded portions of the pair of fastening tapes overlap each other in a state where the pair of flap portions are folded starting from the longitudinal folding line.

Since the folded portions overlapping at least three layers of the fastening tape are overlapped with each other, the thickness of the portion where the fastening tapes are overlapped with each other is further increased. As a result, at least one flap portion is more likely to float upward, and a gap is more likely to be formed under the flap portion. Therefore, the assistant or the user can easily insert the finger due to this gap, and can more easily deploy the flap portion.

According to a preferred embodiment, the folded portion overlaps the sheet constituting the flap portion in the thickness direction of the absorbent article.

Since the folded portion is a portion in which at least three layers are overlapped, the folded portion has higher rigidity than the free end portion. Therefore, when the assistant or the user holds the absorbent article with both hands and bends the absorbent article with the flap folded slightly in the valley fold direction, the absorbent article is folded with the free end of the fastening tape as a fulcrum. The portion acts to lift the sheet constituting the flap upward. As a result, a gap is more likely to occur below the flap portion when placed near the longitudinal fold line. Therefore, the assistant or the user can easily insert his / her finger in the gap under the folded flap, and the flap portion can be more easily deployed.

According to a preferred embodiment, the folded portion is folded so that the portion close to the free end portion in the unfolded state is located closer to the skin surface side than the portion far from the free end portion in the unfolded state.

When the assistant or the user holds the absorbent article with both hands and bends the absorbent article with the flap folded slightly in the valley fold direction, the folding part becomes a fulcrum with the free end of the fastening tape as a fulcrum. It easily acts to lift the sheet that makes up the flap upward. As a result, a gap is more likely to occur below the flap portion when placed near the longitudinal fold line. Therefore, the assistant or the user can easily insert his / her finger in the gap under the folded flap, and the flap portion can be more easily deployed.

According to a preferred embodiment, the fastening tape is non-bonded to the non-skin surface sheet located on the non-skin surface side of the sheet constituting the flap portion at least in the folded portion.

Since the folded portion of the fastening tape is not joined to the non-skin surface sheet located on the non-skin surface side of the fastening tape, the folded portion of the fastening tape is more likely to rise upward than the non-skin surface sheet. Therefore, with the free end of the fastening tape as a fulcrum, the folding portion is more likely to act by lifting the sheet constituting the flap upward. As a result, a gap is more likely to occur below the flap portion when placed near the longitudinal fold line. Therefore, the assistant or the user can easily insert his / her finger in the gap under the folded flap, and the flap portion can be more easily deployed.

According to a preferred embodiment, the folded portion is provided with a hook for engaging the fastening tape with the front waist circumference area.

Since the hook is provided in the folded portion, the rigidity of the folded portion is increased. Therefore, with the free end of the fastening tape as a fulcrum, the folding portion makes it easier to lift the sheet constituting the flap upward. As a result, a gap is more likely to occur below the flap portion when placed near the longitudinal fold line. Therefore, the assistant or the user can easily insert his / her finger in the gap under the folded flap, and the flap portion can be more easily deployed.

According to a preferred embodiment, the length of the folded portion in the width direction is longer than the length from the folded portion to the tip of the fastening tape.

If the length of the folded portion in the width direction is shorter than the length of the free end portion in the width direction, it is difficult for the folded portion to lift the sheet constituting the flap. Therefore, the length of the folded portion in the width direction is preferably longer than the length of the free end portion in the width direction. As a result, a gap is more likely to occur below the flap portion when placed near the longitudinal fold line. Therefore, the assistant or the user can easily insert his / her finger in the gap under the folded flap, and the flap portion can be more easily deployed.

According to a preferred embodiment, there is a waist stretch on the back side of the absorber in the longitudinal direction.

There are areas where it is easy to expand and contract and areas where it is difficult to expand and contract due to the waist expansion and contraction portion. Due to the difference in expansion and contraction of the waist expansion and contraction portion, the pair of folded flap portions may be tilted diagonally with respect to the width direction. Due to the distortion caused by this expansion and contraction, a gap is more likely to be formed on the lower side of the flap portion. Therefore, the assistant or the user can easily insert his / her finger in the gap under the folded flap, and the flap portion can be more easily deployed.

According to a preferred embodiment, the waist stretch extends outward from the outer edge of the absorber in the width direction.

The action of the waist elastic portion pulling the flap portion increases, and the pair of folded flap portions tends to tilt more obliquely with respect to the width direction. As a result, a gap is likely to be formed on the lower side of the flap portion. Therefore, the assistant or the user can easily insert his / her finger in the gap under the folded flap, and the flap portion can be more easily deployed.

According to a preferred embodiment, the waist stretch extends outward from the longitudinal fold line in the width direction.

Since the flap portion in the folded state is also pulled outward in the width direction, the flap portion is more likely to be inclined, and a gap is likely to be generated under the flap portion. Therefore, the assistant or the user can easily insert his / her finger in the gap under the folded flap, and the flap portion can be more easily deployed.

According to a preferred embodiment, the absorbent article has a surface sheet that covers the absorber, and a shape is formed on a portion of the surface sheet that overlaps with the flap portion in a folded state.

The free end of the fastening tape is easily caught in the shaping of the surface sheet. Therefore, if the assistant or the user holds the absorbent article with both hands and bends the absorbent article with the flap folded slightly in the valley fold direction, the free end of the fastening tape does not shift in the width direction. As a result, a gap is more likely to occur below the flap portion. Therefore, the assistant or the user can easily insert his / her finger in the gap under the folded flap, and the flap portion can be more easily deployed.

According to a preferred embodiment, the absorbent article has a pair of leg side gathers provided on both sides of the center of the absorbent article in the width direction, the leg side gathers at least in the inseam area. It extends along the longitudinal direction and a portion of the effective stretch region of the leg side gathers reaches the flap portion.

The leg cather drags the vicinity of the root of the folded flap portion, and a gap is likely to occur in the region near the longitudinal fold line of the folded flap portion. Therefore, the assistant or the user can easily insert the finger due to this gap, and can more easily deploy the flap portion.

The absorbent article 10 may have a pair of leg side gathers 71 provided on both sides of the absorbent article 10 in the width direction W. The leg side gather 71 is formed by an elastic member that can expand and contract in the longitudinal direction L. The elastic member may be made of, for example, a rubber thread. The elastic member constituting the leg side gather 71 may be provided on, for example, the side seat 70.

The absorbent article 10 may have a pair of leg gathers 76 provided on both sides of the absorbent article 10 in the width direction W. The leg gather 76 is formed by an elastic member that can expand and contract in the longitudinal direction L. The elastic member may be made of, for example, a rubber thread or an elastic sheet. The leg gather 76 may be located outside the leg side gather 71 in the width direction.

The absorbent article 10 may have a pair of fastening tapes 90 for fastening the front waist circumference region S1 and the rear waist circumference region S3. Fastening tapes 90 may be provided on both sides of the rear waist circumference region S3 in the width direction W. The fastening tape 90 fastens the front waist circumference region S1 and the rear waist circumference region S3 when the absorbent article 10 is attached. Specifically, the absorbent article 10 is held by the wearer's body by fastening the fastening tape 90 provided in the rear waist circumference area S3 to the front waist circumference area S1.

The absorbent article 10 has a pair of flap portions 80 extending outward from the absorber 40 in the width direction W in the rear waist circumference region S3. The pair of flap portions 80 are folded from the longitudinal folding line FL3 along the longitudinal direction L in the folded state of the absorbent article 10. The pair of flap portions 80 may be valley-folded starting from the longitudinal fold line FL3 when viewed from the skin surface side. The longitudinal folding line FL3 may be located outside the absorber 40 in the width direction W.

The flap portion 80 is defined by a portion of the outer line extending from the rear waist circumference region S3 to the inseam region S2, which is outside the longitudinal direction L, rather than a point at 45 ° with respect to a straight line extending in the width direction W.

The absorbent article 10 has a fastening tape 90 provided on a pair of flaps 80. The fastening tape 90 engages with the front waist circumference region S1 during use. The fastening tape 90 may have a base material 91 fixed to the rear waist circumference region S3 and a hook material 92 provided on the base material 91. A large number of hooks that can be engaged with the front waist circumference region S1 may be provided on one surface (engagement surface) of the hook material 92. The hook material 92 is configured to be engaged with the front waist circumference region S1 at the time of use.

The fastening tape 90 has unfoldable folds that are folded into at least three layers. Specifically, the fastening tape 90 has a mountain fold portion FL2 that is mountain-folded when viewed from the skin surface side and a valley fold portion FL1 that is valley-folded when viewed from the skin surface side in the unfolded state of the fastening tape 90. And may have. In this case, the folded portion is defined by a region between the mountain fold portion FL2 and the valley fold portion FL1 in the folded state of the fastening tape 90, and a region overlapping the region in the thickness direction T.

In the unfolded state of the fastening tape 90, the valley fold portion FL1 may be provided outside the mountain fold portion FL2 in the width direction W. The fastening tape 90 may be folded in three in a state of being folded at the valley fold portion FL1 and the mountain fold portion FL2. In this case, with the fastening tape 90 folded, the free end 93 of the fastening tape 90 extends outward in the width direction W. In the unfolded state of the absorbent article, the free end 93 of the fastening tape 90 may extend outside the flap 80 in the width direction W. The fixed end 94 opposite to the free end 93 of the fastening tape 90 may be fixed to a sheet existing in the rear waist circumference region S3, for example, the front sheet 50 and / or the back sheet 60.

With the fastening tape 90 folded, a portion of the hook member 92 may face another portion of the hook member 92 within the folded and overlapping surfaces (folded portions). That is, the hook material 92 may be provided on both sides of the valley fold portion FL1. In this case, since the hook members 92 face each other in the folded state of the fastening tape 90, it is possible to prevent the hook members 92 from unintentionally adhering to the non-woven fabric constituting the absorbent article 10.

The front waist circumference area S1 or the rear waist circumference area S3 preferably has an accommodating portion 72 accommodating at least a part of the folded fastening tape 90. The accommodating portion 72 may be composed of a sheet member such as the side sheet 70 and the back surface sheet 60 described above.

As described above, when the folded fastening tape 90 is accommodated in the accommodating portion 72, it is preferable that the free end portion 93 of the fastening tape 90 protrudes outward from the accommodating portion 72. When the absorbent article 10 is to be worn by a person requiring assistance, first, the absorbent article is laid on the floor and the person requiring assistance is laid down on the absorbent article. At this time, if the free end portion 93 of the fastening tape 90 projects outward from the accommodating portion 72, the fastening tape 90 can be easily pulled and deployed.

As shown in FIG. 2, in a state where the pair of flap portions 80 are folded starting from the longitudinal folding line FL3, the fastening tapes 90 provided on the pair of flap portions 80 overlap each other. In this case, the thickness of the portion where the fastening tapes 90 overlap each other increases. As a result, at least one flap portion (flap portion located on the upper side) 90 is likely to float upward, and a gap I is likely to be formed under the one flap portion 80. In the example shown in FIG. 2, a gap I is likely to occur under the flap portion 80 on the left side. Therefore, the assistant or the user can easily insert a finger into the gap I and can easily deploy the flap portion 80.

It is preferable that the folded portions of the pair of fastening tapes 90 overlap each other in a state where the pair of flap portions 80 are folded starting from the longitudinal folding line FL3. That is, in a state where the flap portion 80 and the fastening tape 90 are folded, the folded portions overlapping at least three layers of the pair of fastening tape 90 overlap each other. Therefore, the thickness of the portion where the fastening tapes 90 overlap each other is further increased. As a result, at least one flap portion 80 is more likely to float upward, and a gap I is more likely to be generated under the flap portion 80. Therefore, the assistant or the user can easily insert the finger by the gap I, and can more easily deploy the flap portion 80.

In a state where the pair of flap portions 80 are folded starting from the longitudinal folding line FL3, the free end portion 93 of the fastening tape 90 preferably extends to the outside of the flap portion 80 in the width direction W (see also FIG. 8). ). Since the free end 93 of the fastening tape 90 protrudes outside the flap 80, the distance from the free end 93 of the fastening tape 90 to the longitudinal fold line FL3 is longitudinally folded from the outer edge of the flap portion 80 in the width direction W. It will be longer than the distance to line FL3. As a result, the free end 93 of the fastening tape 90, which tends to be the starting point for lifting the flap 80, moves away from the longitudinal fold line FL3, so that a gap I is likely to occur on the lower side of the flap 80 near the longitudinal fold line FL3. Therefore, the assistant or the user can easily insert the finger by the gap I, and can more easily deploy the flap portion 80.

The fastening tape 90 is preferably non-bonded to the non-skin surface sheet (back surface sheet) 60 located on the non-skin surface side of the flap portion 80 among the sheets constituting the flap portion 80, at least in the folded portion. Since the folded portion of the fastening tape 90 is not joined to the non-skin surface sheet 60 located on the non-skin surface side of the fastening tape 90, the folded portion of the fastening tape 90 tends to rise above the non-skin surface sheet 60. It has become. Therefore, with the free end portion 93 of the fastening tape 90 as a fulcrum, the folding portion is more likely to act by lifting the sheet constituting the flap portion 80 upward. As a result, a gap I is more likely to occur below the flap portion when placed near the longitudinal fold line FL3. Therefore, the assistant or the user can easily insert a finger by the gap I on the lower side of the folded flap portion 80, and the flap portion 80 can be more easily deployed.

As previously mentioned. It is preferable that the folding portion is provided with a hook 92 for engaging the fastening tape 90 with the front waist circumference region S1. As a result, the rigidity of the folded portion is increased. Therefore, with the free end 93 of the fastening tape 90 as a fulcrum, the folding portion makes it easier to lift the sheet forming the flap upward. As a result, a gap I is more likely to occur below the flap portion 80 in the vicinity of the longitudinal folding line FL3. Therefore, the assistant or the user can easily put his / her finger in the gap under the folded flap, and the flap portion 80 can be more easily deployed.

The length of the folded portion in the width direction W is preferably longer than the length from the folded portion to the tip of the free end portion 93 of the fastening tape 90. If the length of the folded portion in the width direction W is short, it is difficult for the folded portion to lift the sheet forming the flap portion 80. Therefore, the length of the folded portion in the width direction W is preferably longer than the length from the folded portion to the tip of the free end portion 93 of the fastening tape 90. As a result, a gap I is more likely to occur below the flap portion 80 in the vicinity of the longitudinal folding line FL3.

The folded portion of the fastening tape 90 preferably overlaps the sheet constituting the flap portion 80 in the thickness direction T of the absorbent article 10. Since the folded portion is a portion in which at least three layers are overlapped, the folded portion has higher rigidity than the free end portion 93. Therefore, when the absorbent article with the flap portion 80 folded while the assistant or the user holds the absorbent article with both hands is slightly bent in the valley fold direction, the free end portion 93 of the fastening tape 90 is used as a fulcrum. Then, the folding portion acts to lift the sheet constituting the flap portion 80 upward. As a result, a gap I is more likely to occur below the flap portion 80 in the vicinity of the longitudinal folding line FL3.

The folded portion of the fastening tape 90 is folded so that the portion close to the free end portion 93 in the unfolded state is located closer to the skin surface side than the portion farther from the free end portion 93 in the unfolded state. When the absorbent article 10 with the flap portion 80 folded while the assistant or the user holds the absorbent article with both hands is slightly bent in the valley fold direction, the free end portion 93 of the fastening tape 90 is used as a fulcrum. Therefore, the folding portion easily acts to lift the sheet constituting the flap portion 80 upward. As a result, a gap I is more likely to occur below the flap portion 80 when placed near the longitudinal fold line FL3. Therefore, the assistant or the user can easily insert a finger by the gap on the lower side of the folded flap portion 80, and the flap portion 80 can be more easily deployed.

It is preferable that the shaping is formed on the portion of the surface sheet 50 that overlaps with the flap portion 80 in the folded state. The free end 93 of the fastening tape 90 is easily caught in the shaping of the surface sheet 50. Therefore, when the assistant or the user holds the absorbent article with both hands and bends the absorbent article with the flap folded slightly in the valley fold direction, the free end portion 93 of the fastening tape 90 becomes W in the width direction. As a result, a gap I is more likely to occur below the flap portion 80. Therefore, the assistant or the user can easily insert a finger by the gap I on the lower side of the folded flap portion 80, and the flap portion 80 can be more easily deployed.

As described above, the absorbent article preferably has a waist stretch 85 on the rear side of the absorber 40 in the longitudinal direction L. The waist stretchable portion 85 has a region that easily expands and contracts and a region that does not easily expand and contract. Due to the expansion and contraction of the waist expansion and contraction portion 85, the pair of folded flap portions 80 are inclined obliquely with respect to the width direction W. Due to the distortion due to this expansion and contraction, a gap I is more likely to be formed on the lower side of the flap portion 80. Therefore, the assistant or the user can easily insert a finger by the gap I on the lower side of the folded flap portion 80, and the flap portion can be more easily deployed.

The waist elastic portion 85 preferably extends outward from the outer edge of the absorber 40 in the width direction W. The action of the waist elastic portion 85 pulling the flap portion 80 increases, and the pair of folded flap portions 80 are more likely to tilt more obliquely with respect to the width direction W. As a result, a gap I is likely to be formed on the lower side of the flap portion 80. Therefore, the assistant or the user can easily insert a finger by the gap I on the lower side of the folded flap portion 80, and the flap portion can be more easily deployed.

The waist elastic portion 85 extends outward from the longitudinal folding line FL3 in the width direction W. Since the flap portion 80 in the folded state is also pulled to the outside in the width direction W, the flap portion 80 is more likely to be tilted, and a gap I is likely to be formed under the flap portion 80. Therefore, the assistant or the user can easily insert a finger due to the gap I on the lower side of the folded flap portion 80, and the flap portion 80 can be more easily deployed.

It is preferable that the leg side gather 71 extends along the longitudinal direction L at least in the inseam region S2, and a part of the effective expansion / contraction region of the leg side gather 71 reaches the flap portion 80. Here, the effective expansion / contraction region of the leg side gather 71 is defined by the region of the elastic member joined to the sheet in the stretched state. Since the leg side cather 71 drags the vicinity of the root of the folded flap portion 80, a gap I is likely to occur in the region near the longitudinal folding line FL3 of the folded flap portion 80. Therefore, the assistant or the user can easily insert the finger by the gap I, and can more easily deploy the flap portion 80.
