Absorbent articles are usually in a folded state at the time of packaging. When the assistant or the wearer wears the absorbent article, first, the folded absorbent article is deployed. At this time, if the flap portion of the front waist region is folded at the longitudinal fold line along the longitudinal direction, the operation of expanding the flap portion at the longitudinal fold line may be troublesome.

Therefore, a tape-type absorbent article having a more easily deployable structure is desired.

An absorbent article according to one aspect includes a longitudinal direction, a width direction orthogonal to the longitudinal direction, a front waist region, a rear waist region, and a space between the front waist region and the rear waist region. A crotch region, an absorber disposed at least in the crotch region, a pair of flaps extending outward from the absorber in the width direction in the rear waist region, and the pair of flaps Fastening tapes having hooks engaged with the front waist region. The fastening tape has a deployable fold folded into at least three layers. The flap portion is folded from the longitudinal fold line along the longitudinal direction in the folded state of the absorbent article. In a state where the pair of flaps are folded starting from the longitudinal fold line, the fastening tapes provided on the pair of flaps overlap each other.

FIG. 7 is a cross-sectional view of the fastening tape taken along line F3-F3 shown in FIG. FIG. 8 is a schematic view for explaining a gap which is generated below the folded flap portion.

(1) Outline of Embodiment At least the following matters will become clear by the description of the present specification and the attached drawings.

An absorbent article according to one aspect includes a longitudinal direction, a width direction orthogonal to the longitudinal direction, a front waist region, a rear waist region, and a space between the front waist region and the rear waist region. A crotch region, an absorber disposed at least in the crotch region, a pair of flaps extending outward from the absorber in the width direction in the rear waist region, and the pair of flaps Fastening tapes having hooks engaged with the front waist region. The fastening tape has a deployable fold folded into at least three layers, and the flap is folded starting from the longitudinal fold line along the longitudinal direction in the folded state of the absorbent article The fastening tapes provided on the pair of flaps overlap each other in a state in which the pair of flaps are folded starting from the longitudinal fold line.

Since the pair of fastening tapes overlap each other in the state where the flap portion is folded, the thickness of the portion where the fastening tapes overlap each other is increased. As a result, at least one of the flaps (the flap located at the upper side) tends to float upward, and a gap is likely to be generated below the one flap. Therefore, the assistant or the user can easily insert the finger by this gap, and the flap can be easily deployed.

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

Because the free end of the fastening tape extends out of the flap, the distance from the free end of the flap to the longitudinal fold can be relatively long. As a result, the free end of the fastening tape, which is the bending start point of the flap portion, moves away from the longitudinal fold line, so that a gap is easily formed on the lower side of the flap near the longitudinal fold line. Therefore, the assistant or the user can easily insert the finger by this gap, and the flap can be more easily deployed.

According to a preferred aspect, in a state where the pair of flaps are folded from the longitudinal fold line, the folded portions of the pair of fastening tapes overlap.

Since the folds overlapping at least three layers of the fastening tape overlap, the thickness of the overlapping part of the fastening tape is further increased. As a result, at least one flap portion is more likely to be lifted upward, and a gap is more likely to be generated below the flap portion. Therefore, the assistant or the user can easily insert the finger by this gap, and the flap can be more easily deployed.

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

The fold is higher in rigidity than the free end because it is an overlapping portion of at least three layers. Therefore, if the assistant or the user holds the absorbent article with both hands and bends the absorbent article in the folded state slightly in the valley folding direction, the free end of the fastening tape is used as a fulcrum to fold the absorbent article. The part acts to lift the sheet constituting the flap upwards. As a result, a gap is more likely to be generated below the flap portion when placed near the longitudinal fold line. Therefore, the assistant or the user can easily put in a finger by the gap on the lower side of the folded flap, and the flap portion can be more easily deployed.

According to a preferred aspect, the folded portion is folded such that a portion close to the free end in the unfolded state is located closer to the skin surface than a portion further from the free end 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 folding direction, the folding section is supported by the free end of the fastening tape as a fulcrum It tends to lift the sheet constituting the flap upward. As a result, a gap is more likely to be generated below the flap portion when placed near the longitudinal fold line. Therefore, the assistant or the user can easily put in a finger by the gap on the lower side of the folded flap, and the flap portion can be more easily deployed.

According to a preferred aspect, the fastening tape is not joined to a non-skin surface sheet positioned on the non-skin surface side of the fastening tape among the sheets constituting the flap section at least in the folding portion.

Since the folded portion of the fastening tape is not joined to the non-skin 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 sheet. Therefore, with the free end of the fastening tape as a fulcrum point, the folding section acts more easily to lift the sheet constituting the flap upward. As a result, a gap is more likely to be generated below the flap portion when placed near the longitudinal fold line. Therefore, the assistant or the user can easily put in a finger by the gap on the lower side of the folded flap, and the flap portion can be more easily deployed.

According to a preferred embodiment, the folding portion is provided with a hook for engaging the fastening tape with the front waist region.

Since the hooks are provided at the folding portion, the rigidity of the folding portion is enhanced. Therefore, with the free end portion of the fastening tape as a fulcrum, the folding portion can easily lift the sheet constituting the flap upward. As a result, a gap is more likely to be generated below the flap portion when placed near the longitudinal fold line. Therefore, the assistant or the user can easily put in a finger by the gap on the lower side of the folded flap, and the flap portion can be more easily deployed.

According to a preferred aspect, the length of the fold in the width direction is longer than the length from the fold to the tip of the fastening tape.

If the length of the fold in the width direction is shorter than the length of the free end in the width direction, it is difficult for the fold to lift the sheet constituting the flap. Therefore, it is preferable that the length of the fold in the width direction is longer than the length of the free end in the width direction. As a result, a gap is more likely to be generated below the flap portion when placed near the longitudinal fold line. Therefore, the assistant or the user can easily put in a finger by the gap on the lower side of the folded flap, and the flap portion can be more easily deployed.

According to a preferred embodiment, a waist stretchable portion is provided on the rear side of the absorber in the longitudinal direction.

There are an area which is easily expanded and contracted and an area which is not easily expanded and contracted by the waist expansion and contraction part. Due to the difference in expansion and contraction of the waist expansion and contraction portion, the pair of folded flap portions may be inclined with respect to the width direction. The distortion due to the expansion and contraction makes the gap easier to be created on the lower side of the flap portion. Therefore, the assistant or the user can easily put in a finger by the gap on the lower side of the folded flap, and the flap portion can be more easily deployed.

According to a preferred aspect, the waist elastic portion extends outward in the width direction beyond the outer edge of the absorber.

The action of the waist expansion and contraction unit pulling the flaps is increased, and the pair of folded flaps can be more easily inclined obliquely with respect to the width direction. As a result, the gap is more easily formed on the lower side of the flap portion. Therefore, the assistant or the user can easily put in a finger by the gap on the lower side of the folded flap, and the flap portion can be more easily deployed.

According to a preferred aspect, the waist elastic portion extends outward in the width direction beyond the longitudinal fold line.

Since the flap part in the folded state is also pulled to the outside in the width direction, the flap part is more easily inclined, and a gap tends to be generated below the flap part. Therefore, the assistant or the user can easily put in a finger by the gap on the lower side of the folded flap, and the flap portion can be more easily deployed.

According to a preferred aspect, the absorbent article has a surface sheet covering the absorber, and the shape is formed on the portion of the surface sheet overlapping the flap portion in the folded state.

The free end of the fastening tape is easily caught in the shaping of the top sheet. Therefore, when the assistant or the user holds the absorbent article with both hands and bends the absorbent article in the folded state slightly in the valley folding direction, the free end of the fastening tape does not shift in the width direction. This makes the gap more likely to occur below the flap. Therefore, the assistant or the user can easily put in a finger by the gap on the lower side of the folded flap, and the flap portion can be more easily deployed.

According to a preferred aspect, 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, and the leg side gathers at least in the crotch region It extends along the longitudinal direction, and a part of an effective elastic area of the leg side gathers reaches the flap.

The leg gathers pull near the root of the folded flaps, and the area near the longitudinal fold line of the folded flaps tends to create a gap. Therefore, the assistant or the user can easily insert the finger by this gap, and the flap can be more easily deployed.

The side sheet 70 may extend in the longitudinal direction L over the front waistline region S1, the crotch region S2, and the rear waistline region S3. The side sheet 70 may be configured of one or two or more stacked non-woven fabrics.

The absorbent article 10 may have a waist stretch portion 85 on the rear side of the absorber 40 in the longitudinal direction L. The waist stretch unit 85 is formed of an elastic member that can stretch in the width direction W. The elastic member may be made of, for example, a rubber thread or an elastic sheet.

The absorbent article 10 may have a pair of leg side gathers 71 provided on both sides of the center of the absorbent article 10 in the width direction W. The leg side gathers 71 are formed of 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 members constituting the leg side gathers 71 may be provided, for example, on the side seat 70.

The absorbent article 10 may have a pair of leg gathers 76 provided on both sides of the center of the absorbent article 10 in the width direction W. The leg gathers 76 are formed by elastic members that can extend 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 gathers 76 may be located outside the leg side gathers 71 in the width direction.

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

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

Flap portion 80 is defined by a portion outside longitudinal direction L than a point of 45 ° with respect to a straight line extending in width direction W in the outline continuous from back waist area S3 to crotch area S2. .

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 area S1 in use. The fastening tape 90 may have a base material 91 fixed to the back waistline area S3 and a hook material 92 provided on the base material 91. One surface (engagement surface) of the hook member 92 may be provided with a large number of hooks that can be engaged with the front waist area S1. The hook member 92 is configured to be engageable with the front waist area S1 in use.

The fastening tape 90 has a deployable fold folded into at least three layers. Specifically, in the unfolded state of the fastening tape 90, the fastening tape 90 has a mountain fold portion FL2 that is mountain folded as viewed from the skin side and a valley fold portion FL1 that is valley folded as viewed from the skin side. And may be included. In this case, in the folded state of the fastening tape 90, the folding portion is defined by a region between the mountain fold portion FL2 and the valley fold portion FL1 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, the free end 93 of the fastening tape 90 extends outward in the width direction W with the fastening tape 90 folded. 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 present in the back waist area S3, for example, the top sheet 50 and / or the non-skin sheet 60.

In the folded state of the fastening tape 90, a part of the hooking material 92 may face another part of the hooking material 92 in a face folded (folded portion). That is, the hook members 92 may be provided on both sides of the valley fold portion FL1. In this case, since the hook materials 92 face each other in a state where the fastening tape 90 is folded, it is possible to suppress the hook materials 92 from being unintentionally attached to the nonwoven fabric constituting the absorbent article 10.

It is preferable that the front waistline region S1 or the rear waistline region S3 have a receiving portion 72 for receiving at least a part of the fastening tape 90 in a folded state. The housing portion 72 may be configured by a sheet member such as the side sheet 70 or the non-skin 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 93 of the fastening tape 90 protrudes from the accommodating portion 72 to the outside. When the absorbent article 10 is to be worn by the assistant, first, the absorbent article is laid on the floor, and the assistant is laid on the absorbent article. At this time, when the free end portion 93 of the fastening tape 90 protrudes from the housing portion 72 to the outside, the fastening tape 90 can be easily pulled and developed.

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

It is preferable that the folded portions of the pair of fastening tapes 90 overlap in a state where the pair of flaps 80 is folded starting from the longitudinal fold 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 tapes 90 overlap each other. Accordingly, the thickness of the overlapping portion of the fastening tapes 90 is further increased. As a result, at least one of the flaps 80 is more likely to float upward, and a gap I is more likely to be generated below the flaps 80. Therefore, the assistant or the user can easily insert the finger by the gap I, and the flap 80 can be more easily deployed.

It is preferable that the free end 93 of the fastening tape 90 extend to the outside of the flap 80 in the width direction W in a state where the pair of flaps 80 is folded from the longitudinal fold line FL3 (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 longer than the outer edge of the flap 80 in the width direction W It is longer than the distance to the line FL3. As a result, the free end 93 of the fastening tape 90, which tends to be a starting point for lifting up the flap portion 80, goes away from the longitudinal fold line FL3, the gap I is easily generated by 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 the flap 80 can be more easily deployed.

It is preferable that the fastening tape 90 is not joined to the non-skin surface sheet (non-skin surface sheet) 60 located at the non-skin surface side of the fastening tape 90 among the sheets constituting the flap section 80 at least in the folding section. . Since the folding portion of the fastening tape 90 is not joined to the non-skin sheet 60 positioned on the non-skin surface side relative to the fastening tape 90, the folding portion of the fastening tape 90 is likely to float upward above the non-skin sheet 60 It has become. Therefore, with the free end 93 of the fastening tape 90 as a fulcrum, the folding portion is more likely to lift the sheet constituting the flap portion 80 upward. As a result, the gap I is more likely to be generated 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 under the folded flap portion 80, and the flap portion 80 can be more easily deployed.

As described above, it is preferable that the folding portion be provided with the hook 92 for engaging the fastening tape 90 with the front waist area S1. Thereby, the rigidity of the folding portion is enhanced. Therefore, with the free end 93 of the fastening tape 90 as a fulcrum, the folded portion can more easily lift the sheet constituting the flap upward. Thereby, in the vicinity of the longitudinal fold line FL3, the gap I is more easily generated below the flap portion 80. Therefore, the assistant or the user can easily put in a finger by the gap on the lower side of the folded flap, and the flap 80 can be more easily deployed.

The length of the fold in the width direction W is preferably longer than the length from the fold to the tip of the free end 93 of the fastening tape 90. If the length of the folding portion in the width direction W is short, the folding portion does not easily lift the sheet constituting the flap portion 80. Therefore, the length of the fold in the width direction W is preferably longer than the length from the fold to the tip of the free end 93 of the fastening tape 90. Thereby, in the vicinity of the longitudinal fold line FL3, the gap I is more easily generated below the flap portion 80.

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. The folded portion is higher in rigidity than the free end 93 because it is an overlapping portion of at least three layers. Therefore, when the assistant or the user holds the absorbent article with both hands and bends the absorbent article in a state in which the flap portion 80 is folded slightly in the valley folding direction, the free end 93 of the fastening tape 90 is fulcrum Then, the folding portion acts to lift the sheet constituting the flap portion 80 upward. Thereby, in the vicinity of the longitudinal fold line FL3, the gap I is more easily generated below the flap portion 80.

The folded portion of the fastening tape 90 is folded so that the portion close to the free end 93 in the unfolded state is located closer to the skin surface than the portion further from the free end 93 in the unfolded state. When the assistant or user holds the absorbent article with both hands and bends the absorbent article 10 with the flap 80 folded in the valley folding direction slightly, the free end 93 of the fastening tape 90 is used as a fulcrum. Thus, the folding portion tends to lift the sheet constituting the flap portion 80 upward. Thereby, the gap I is more likely to be generated below the flap portion 80 by being placed near the longitudinal fold line FL3. Therefore, the assistant or the user can easily insert a finger by the gap under the folded flap portion 80, and the flap portion 80 can be more easily deployed.

It is preferable that a shaping is formed on a portion of the topsheet 50 overlapping the flap 80 in a folded state. The free end 93 of the fastening tape 90 is easily caught in the shaping of the top sheet 50. Therefore, when the assistant or the user holds the absorbent article with both hands and bends the absorbent article in a folded state slightly in the valley folding direction, the free end 93 of the fastening tape 90 is in the width direction W As a result, the gap I is more likely to occur below the flap 80. Therefore, the assistant or the user can easily insert a finger by the gap I under 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 stretchable portion 85 on the rear side of the absorber 40 in the longitudinal direction L. There are an area which is easily expanded and contracted and an area which is not easily expanded and contracted by the waist expansion and contraction part 85. By the expansion and contraction of the waist expansion and contraction portion 85, the pair of folded flap portions 80 inclines obliquely to the width direction W. Due to the distortion due to the expansion and contraction, the gap I is more easily formed below the flap portion 80. Therefore, the assistant or user can easily insert a finger by the gap I under the folded flap portion 80, and the flap portion can be more easily deployed.

It is preferable that the waist expansion and contraction portion 85 extend outward in the width direction W beyond the outer edge of the absorber 40. The action of the waist stretchable portion 85 pulling the flap portion 80 is increased, and the pair of folded flap portions 80 can be more easily inclined at an angle with respect to the width direction W. As a result, the gap I is more easily formed on the lower side of the flap portion 80. Therefore, the assistant or user can easily insert a finger by the gap I under the folded flap portion 80, and the flap portion can be more easily deployed.

The waist stretch unit 85 extends outward in the width direction W beyond the longitudinal fold line FL3. Since the folded flap portion 80 is also pulled to the outside in the width direction W, the flap portion 80 is more easily inclined, and the gap I is easily generated below the flap portion 80. Therefore, the assistant or the user can easily insert a finger by the gap I under the folded flap portion 80, and the flap portion 80 can be more easily deployed.

It is preferable that the leg side gathers 71 extend along the longitudinal direction L at least in the crotch region S2, and a part of the effective stretch area of the leg side gathers 71 reaches the flap portion 80. Here, the effective stretch area of the leg side gathers 71 is defined by the area of the elastic member joined to the sheet in the stretched state. Since the vicinity of the root of the folded flap portion 80 is dragged by the leg side gathers 71, a gap I is likely to be generated in the region near the longitudinal fold line FL3 of the folded flap portion 80. Therefore, the assistant or the user can easily insert the finger by the gap I, and the flap 80 can be more easily deployed.
