Description

The present invention relates to a pants-type absorbent article.

Pants-type absorbent articles such as pants-type disposable diapers are designed so that auxiliary absorbent pads can be stacked on the inner surface thereof, that is, on the side that contacts the skin of the wearer (user) wearing the pants-type absorbent article. It has become. In this case, the used auxiliary absorbent pad can be replaced with an unused one and the outer pants-shaped absorbent article can be reused, so that the amount of pants-shaped absorbent article consumed can be suppressed.

When wearing an auxiliary absorbent pad over a pant-type absorbent article, the wearer should lower the pant-type absorbent article to below the knees while sitting on a toilet seat, etc., and insert the inner crotch area upward through the opening in the waist of the pant-type absorbent article. Look down and place an auxiliary absorbent pad in the crotch area.

Here, the wearer folds the auxiliary absorbent pad in half in the longitudinal direction with the surface in contact with the wearer's skin facing inside, holds the auxiliary absorbent pad in his hand with the fold of the bi-fold facing down, and holds the auxiliary absorbent pad in the pant-type absorbent article. Insert it into the inner crotch part of the auxiliary absorbent pad so that the fold of the auxiliary absorbent pad is against the crotch part.

In this state, the wearer holds the upper end of the front part of the auxiliary absorbent pad, which has been folded in two, with one hand, and the upper end of the back part with the other hand, and folds the fold. By opening forward and backward at the center, the auxiliary absorbent pad is unfolded in a bi-folded state. Then, the wearer locks the fastening part provided on the outer surface near the upper end of the front-opening part to the absorbent body or top sheet on the inner surface of the ventral part of the pants-type absorbent article, and then opens the pants-type absorbent article. The auxiliary absorbent pad is fixed to the pants-type absorbent article by locking the fastening portion provided on the outer surface near the upper end of the section to the absorbent core or top sheet on the inner surface of the back side of the pants-type absorbent article.

However, when the wearer butts the fold of the auxiliary absorbent pad against the crotch of the pants-type absorbent article, the target position at which the fold hits the crotch of the pants-type absorbent article largely depends on the wearer's intuition. Moreover, the shape of the pants-type absorbent article when the article is lowered below the knees differs each time, and the viewing angle when the wearer looks into the crotch from above also differs each time. For this reason, it is difficult for the wearer to maintain a constant target position where the wearer hits the folds of the auxiliary absorbent pad.

By the way, an invention of an absorbent article in which a mark visible from the outside is provided on the diaper at a position corresponding to the wearer's groin area so that the diaper can be worn at an appropriate position on the wearer's body. (For example, see Patent Document 1) and a display area in which a display is formed in an area overlapping with wrinkles formed in a sheet member constituting an absorbent article, and the display area is displayed by stretching the wrinkles. An invention of an absorbent article (for example, see Patent Document 2) has been proposed.

[composition]
<Pants-type disposable diaper>
FIG. 1 is a perspective view showing a pants-type disposable diaper 100 assumed to be worn by a wearer 300, FIG. 2 is a plan view showing a state in which both sides of the pants-type disposable diaper 100 are separated and opened from front to back, and FIG. 2 is a cross-sectional view taken along the line AA in FIG. 2, and FIG. 4 is a cross-sectional view taken along the line BB in FIG. 2. The illustrated pants-type disposable diaper 100 is an embodiment of the pants-type absorbent article according to the present invention.

The pants-type disposable diaper 100 (hereinafter simply referred to as the diaper 100) shown in FIG. 1 has a ventral part 110, a crotch part 120, and a back part 130 that are continuous in the length direction L. The abdominal part 110 corresponds to a part of the diaper 100 that mainly covers the lower abdomen on the ventral side of the wearer (user) 300, and the crotch part 120 corresponds to a part that mainly covers the groin part of the wearer 300. However, the back side portion 130 corresponds to a portion that mainly covers the buttocks of the wearer. In addition, in the plan view shown in FIG. 2, the direction perpendicular to the longitudinal direction (front-back direction) L is defined as the width direction W. The width direction W corresponds to the circumferential direction of the waist of the wearer 300 when the diaper 100 is worn by the wearer 300.

In the diaper 100, one side 111 in the width direction W of the abdominal part 110 and one side 131 in the width direction W of the back part 130 are joined, and The other side 112 of the portion 110 in the width direction W and the other side 132 of the back side portion 130 in the width direction W are joined. As a result, the ventral side part 110 and the dorsal side part 130 are connected in the circumferential direction of the waist of the wearer 300, as shown in FIG. and underbody openings P2 and P3 are formed on both sides of the crotch portion 120.

Further, as shown in FIG. 3, the diaper 100 has an exterior sheet 140 disposed on the lower side in the thickness direction D, that is, on the outer side (non-skin side) far from the skin of the wearer 300. In the diaper 100, the absorbent body 150 is disposed on the upper side in the thickness direction D, that is, on the inner surface side (skin side) that contacts the skin of the wearer 300. Further, a waist nonwoven fabric 170 is disposed over the entire region of the abdominal part 110 and the back part 130 in the width direction W so as to cover both ends of the absorber 150 in the length direction L from the skin side.

As shown in FIG. 3, the absorbent body 150 includes an absorbent member 152 in which pulp fibers are entwined and distributed with superabsorbent resin (SAP), and a liquid-permeable sheet 151 on the surface facing the skin. It is sandwiched between the liquid-impermeable sheet 153 on the back side and the skin side. The aforementioned gather sheet 160 is partially sandwiched and joined between the liquid-impermeable sheet 153 and the exterior sheet 140. As shown in FIG. 2, the absorbent body 150 is arranged in the length direction L over about half of the total length of the ventral part 110, the entire length of the crotch part 120, and about half of the total length of the dorsal part 130. There is.

(landmark)
A mark 10 is formed in the absorber 150 at approximately the center of the crotch portion 120 in the length direction L, which is a target position against which an auxiliary absorbent pad 200, which will be described later, is used to overlap the diaper 100. The mark 10 is formed to extend linearly along the width direction W of the diaper 100 when viewed from above in FIG. 2 .

The mark 10 is formed to have a symmetrical length with respect to the center C of the diaper 100 in the width direction W. The length W1 in the longitudinal direction of the mark 10 is longer than the width W0 of the auxiliary absorbent pad 200 (see FIG. 5), but may be the same length as the width W0 of the auxiliary absorbent pad 200, or It may be shorter than the width W0.

Further, the width d1, which is the dimension in the direction perpendicular to the longitudinal direction of the mark 10 (corresponding to the width direction W of the diaper 100), is the thickness d0 when the auxiliary absorbent pad 200 is folded in half (see FIG. 5). ), the width may be the same as the thickness d0 of the auxiliary absorbent pad 200, or it may be thinner than the thickness d0 of the auxiliary absorbent pad 200.

The width d1 is a width suitable for lightly pinching the portion of the auxiliary absorbent pad 200 near the fold line 240 between the front and rear portions of the absorbent body 150 that sandwich the mark 10, due to the action of the elastic member 20, which will be described later. It is preferable that there be.

As shown in FIG. 4 as an example, the mark 10 is formed by joining a liquid-permeable sheet 151 on the front surface of the absorber 150 and a liquid-impermeable sheet 153 on the back surface such that the dimension in the thickness direction D is other than that of the mark 10. It is formed thinner than the . In other words, at the mark 10, the absorbent member 152 is not arranged at all, or even if the absorbent member 152 is arranged, the liquid permeable sheet 151 and the liquid impermeable sheet are compressed in the thickness direction D. 153, the thickness is reduced. Note that even if the absorbing member 152 is placed at the mark 10, it will not function to absorb liquid.

The mark 10 in the above example is formed by removing or thinning the absorbing member 152 in advance to form a slit that is thinner than the other parts except for the mark 10. The liquid-permeable sheet 151 and the liquid-impermeable sheet 153 are bonded together using heat.

In this way, the mark 10 is formed to be thinner than the parts other than the mark 10, so that the wearer 300 can easily understand the difference in the thickness based on the difference in thickness or the difference in transparency in the thickness direction. , the landmark 10 can be visually recognized. Note that when the mark 10 is formed with different thicknesses as in this example, it can be recognized not only visually but also tactilely.

Note that the mark 10 formed by thermally bonding the liquid-permeable sheet 151 and the liquid-impermeable sheet 153 is liquid-impermeable.

(guiding part)
Further, as shown in FIG. 2, in the diaper 100 of the present embodiment, each end 10a of the mark 10 is bifurcated outward in the width direction W, and has, for example, a V-shaped guide portion 12. has been done. The guide portion 12 is configured such that when the diaper 100 is folded in two along the mark 10, both sides of the crotch portion 120 (leg openings P2, P3) are folded into a front portion (abdominal portion 110) overlapped in half. and the front half of the crotch section 120) and the rear section (the back section 130 and the rear half of the crotch section 120). This guide portion 12 is formed with the same structure as the mark 10 described above.

The two portions 12a along each straight line K forming the V-shape of the bifurcated guide portion 12 are inclined to the front side in the length direction L with respect to the width direction W, and at the rear of the length direction L with respect to the width direction W. The side inclination is the same. That is, the two portions 12a, 12a are formed in line symmetry with respect to the width direction W.

Then, when the diaper 100 is folded in half along the crease along the mark 10, each portion 12a along the straight line K becomes a fold, and both sides of the crotch section 120 are folded inward.

(elastic member)
Further, as shown in FIG. 2, in the outer region in the width direction W from the vicinity of each end 10a of the mark 10 (for example, a rectangular region indicated by a solid line in FIG. 2), and as shown in FIG. An elastic member 20 is attached to the liquid-permeable sheet 151 on the skin side of the body 150 to apply an elastic force F in a direction to shorten the length along the length direction L.

The elastic member 20 is composed of, for example, a plurality of rubber threads stretched along the length direction L fixed to a nonwoven fabric, or an elastic film stretched along the length direction L. Ru.

As shown in FIGS. 2 and 4, the elastic member 20 uses its elastic force F to contract the liquid permeable sheet 151 disposed on the skin surface side of the absorber 150 in the length direction L. On the other hand, the liquid-impermeable sheet 153 disposed on the non-skin surface side of the absorber 150 cannot be shrunk. Therefore, the elastic member 20 applies a load to the absorbent body 150 that deforms the absorbent body 150 so that the skin side of the absorbent body 150 faces inside.

<Auxiliary absorption pad>
FIG. 5 is a perspective view showing the auxiliary absorbent pad 200 folded in half, and FIG. 6 is a schematic diagram showing the auxiliary absorbent pad 200 in a state where the fold line 240 is in contact with the crotch portion 120 on the inner surface of the diaper 100. , FIG. 7 is a schematic diagram showing a state in which the auxiliary absorbent pad 200 is used, with the front part 210 facing the ventral part 110 of the diaper 100 and the rear part 220 facing the back part 130.

The auxiliary absorbent pad 200 shown in FIG. 5 is an example of an auxiliary absorbent pad used to overlap the diaper 100 of this embodiment. The auxiliary absorbent pad 200 is formed into an elongated rectangle. When the wearer 300 places the auxiliary absorbent pad 200 over the diaper 100, as shown in FIG. It should be folded in half.

Then, the wearer 300 holds the folded auxiliary absorbent pad 200 with the fold line 240 facing downward, holding the upper end portions 211 and 221 between the hands, and as shown in FIG. into the crotch part 120 of the auxiliary absorbent pad 200 so that the fold 240 of the auxiliary absorbent pad 200 is in contact with the crotch part 120.

The auxiliary absorbent pad 200 is used with the front part 210 and the rear part 220 folded in half opened so as to be separated from each other in the front and back, as shown by the two-dot chain line in FIG. Ru. That is, the auxiliary absorbent pad 200 is inserted into the inner surface of the crotch portion 120 of the diaper 100 in a folded state as shown in FIG. The diaper 110 is opened toward the rear portion 110 and the rear portion 220 is opened toward the dorsal side portion 130, so that the diaper 100 is stacked on the inner surface of the diaper 100 and used.

The auxiliary absorbent pad 200 is provided with a fastening part 213 at the illustrated upper end 211 of the front part 210 on the outer surface in the folded state shown in FIG. A fastening portion 223 similar to the fastening portion 213 is also provided at the illustrated upper end portion 221 on the outer surface of the rear portion 220 . The fastening parts 213 and 223 engage with the liquid-permeable sheet 151 of the absorber 150 arranged on the inner surface of the diaper 100 when the auxiliary absorbent pad 200 is stacked on the inner surface of the diaper 100. The engagement prevents the auxiliary absorbent pad 200 from shifting relative to the diaper 100.

[Effect]
The diaper 100 of this embodiment has the following effects. That is, when wearing the auxiliary absorbent pad 200 over the diaper 100, the wearer 300 lowers the diaper 100 to below the knees while sitting on a toilet seat or the like, and then lowers the fold line 240 of the auxiliary absorbent pad 200 folded in two. Hold it in your hand, look through the waist opening P1 of the diaper 100 into the inner crotch 120 from above, insert the auxiliary absorbent pad 200 from the waist opening P1 into the crotch 120, and press the crease. 240 is brought into contact with the crotch portion 120.

Here, since the diaper 100 is formed with a mark 10 that serves as a guide for the position where the fold line 240 of the auxiliary absorbent pad 200 hits, the wearer 300 passes the mark 10 of the crotch region 120 from above through the waist opening P1. can be visually recognized. The wearer 300 determines the mark 10 as a target position to which the fold line 240 of the auxiliary absorbent pad 200 is to abut, and abuts the fold line 240 of the auxiliary absorbent pad 200 to this mark 10.

Then, as shown in FIG. 5, the wearer 300 holds the upper end 211 of the front part 210 of the auxiliary absorbent pad 200, which has been folded in two in two layers, with one hand, and holds the upper end 211 of the rear part 220 with one hand. 221 with the other hand, and with the fold line 240 abutting the mark 10, open the front part 210 and the rear part 220 back and forth around the fold line 240 to open the auxiliary absorbent pad 200 in a two-folded state. Expand back and forth.

The wearer 300 locks the fastening part 213 of the front part 210 that opens forward to the absorbent body 150 that extends to the ventral part 110 of the diaper 100, and fixes the fastening part 223 of the rear part 220 that opens backward. is secured to the absorbent body 150 extending to the back side portion 130 of the diaper 100. This fixes the auxiliary absorbent pad 200 to the diaper 100.

As described above, since the diaper 100 of the embodiment is formed with the mark 10 that can be visually recognized by the wearer 300 as the target position, the wearer 300 can easily locate the diaper 100 where the fold line 240 of the auxiliary absorbent pad 200 should hit. The target position can be visually confirmed. As a result, the wearer 300 can place the fold line 240 of the auxiliary absorbent pad 200 in alignment with the mark 10 of the diaper 100 while visually confirming the mark 10 of the diaper 100.

Therefore, in the diaper 100 of the embodiment, when the wearer 300 unfolds the auxiliary absorbent pad 200 back and forth and fixes the auxiliary absorbent pad 200 to the diaper 100, the length direction L of the auxiliary absorbent pad 200 with respect to the diaper 100 is The arrangement position along can be kept constant at all times.

Further, since the mark 10 is formed to have a symmetrical length with respect to the center C in the width direction W of the diaper 100, when the wearer 300 aligns the fold line 240 of the auxiliary absorbent pad 200 with the mark 10, In addition, each end and position of the fold line 240 relative to each end 10a of the mark 10 can be visually recognized.

Thereby, the wearer 300 can make the positional relationship between the left end of the fold 240 and the left end 10a of the mark 10 and the positional relationship between the right end of the fold 240 and the right end 10a of the mark 10 equal on the left and right sides. By adjusting the position of the fold line 240 with respect to the mark 10 along the width direction W while visually checking the position, the auxiliary absorbent pad 200 can be positioned evenly on the left and right sides with respect to the center C of the diaper 100 in the width direction W. can be placed.

Therefore, the mark 10 can also keep the placement position of the auxiliary absorbent pad 200 in the diaper 100 constant along the width direction W when the auxiliary absorbent pad 200 is placed in the diaper 100.

FIG. 8 is a schematic diagram showing a state in which the elastic member 20 applies an elastic force F to the absorbent body 150 so that the front and rear parts of the absorbent body 150 with the mark 10 in between face each other with the skin side facing inside. It is a diagram.

In the diaper 100 of this embodiment, the elastic member 20 provided on the absorbent body 150 is arranged such that the front and rear portions of the absorbent body 150 are arranged with the skin side inward, with the mark 10 in between, as shown by the arrow in FIG. An elastic force F is applied to the absorbent body 150 to cause it to deform so as to face each other. Therefore, as shown in FIG. 6, when the fold line 240 of the auxiliary absorbent pad 200 hits the mark 10, as shown in FIG. The portions sandwich the auxiliary absorbent pad 200 that is abutted against the mark 10.

Thereby, the diaper 100 can be held by lightly sandwiching the portion of the auxiliary absorbent pad 200 near the fold line 240 between the absorbent body 150. Therefore, the diaper 100 can prevent the auxiliary absorbent pad 200 from being displaced during the period before the fastening parts 213 and 223 are fixed to the diaper 100.

In the diaper 10 of this embodiment, the elastic member 20 is arranged on the liquid-permeable sheet 151 on the skin side of the absorber 150, but the elastic member 20 is not arranged on the liquid-permeable sheet 151 on the skin side. For example, it may be placed on the liquid-impermeable sheet 153 on the non-skin surface side, or it may be placed on a portion other than the absorbent body 150. That is, in the diaper 100 of the present embodiment, the elastic member 20 may be arranged by deforming the absorber 150 such that the absorber 150 faces each other with the skin side facing inside, and there is no limitation on the arrangement thereof.

<Other aspects of landmarks>
The mark 10 in the diaper 100 only needs to be visible to the wearer 300, and is not limited to the embodiment described above. For example, without removing or thinning the absorbent member 152 in advance, that is, the mark 10 remains the same thickness as the portion of the absorbent body 150 other than the mark 10, and the peripheral edge forming the outline of the mark 10 is The mark 10 may be made thin by compressing it in the thickness direction D, and at the thinned periphery, the liquid-permeable sheet 151 and the liquid-impermeable sheet 153 are bonded by heat to form only a thin outline. .

In addition, the mark 10 can be fit-embossed by fit-embossing only the periphery of the absorber 150 or the entire mark 10 including the periphery and the area inside thereof, while keeping the same thickness as the portion of the absorber 150 other than the mark 10. (Many dot-shaped compression marks formed by embossing) may be formed.

Furthermore, the mark 10 combines the heat bonding between the liquid-permeable sheet 151 and the liquid-impermeable sheet 153 in the portion where the slit is formed, and the fit embossing formed outside the outline of the slit. It may be something.

The mark 10 formed by the above-mentioned slit or fit embossing has a difference in thickness from the part other than the mark 10, so it can be recognized visually as well as tactilely. It is.

FIG. 9 is a plan view corresponding to FIG. 2 showing the uncolored mark 10 surrounded by the colored area by coloring the surrounding area 30. The mark 10 on the diaper 100 may be only visually recognizable. That is, as shown in FIG. 9, for example, by coloring the area 30 around the landmark 10, the uncolored landmark 10 surrounded by the colored surrounding area 30 can be colored. It may also be something that allows for visual recognition.

In addition, although what is shown in FIG. 9 shows a region 30 around the mark 10 and the guide portion 12 as a colored region, the guide portion 12 that does not need to be recognized by the wearer 300 is colored. Instead of providing a colored area in the surrounding area 30, only the area 30 surrounding the mark 10 may be the colored area.

Further, the surrounding area 30 may be evenly and uniformly filled with a predetermined color, but in this case, the liquid permeability of the filled colored area may be reduced. Therefore, the colored area is not formed by filling it with a predetermined color, but by forming a large number of small colored dots dispersed in the surrounding area 30, the surrounding area 30 as a whole becomes a colored area. It may be formed so that it can be visually recognized. In this case, liquid permeability is ensured in the region excluding the dotted portions where small colored dots are formed, which is preferable.

In the example described above, by coloring the area 30 around the landmark 10, the uncolored landmark 10 was made visible, but instead of coloring the surrounding area 30, by coloring the landmark 10 itself, The mark 10 may be made visible. That is, the mark may be formed on the absorber 150 so that it can be visually recognized by the difference in color between the absorber 150 and the portion other than the mark 10.

Note that the mark in the pants-type absorbent article according to the present invention does not have to be formed in the shape of an elongated rectangle like the mark 10 of each form described above. That is, instead of forming the outline of the elongated rectangular area that is the mark, the mark in the pants-type absorbent article according to the present invention has a mark such as "pad attachment position" within the elongated rectangular area that is the mark. By printing the character string, the range of the printed character string may be visually recognized as a mark. The characters in this case may be formed by a collection of small dots as described above.

The diaper 10 of this embodiment has an elastic member 20 that deforms the skin sides of the front and rear absorbers 150 to face each other with the mark 10 in between. However, the elastic member 20 is not essential. Therefore, the pants-type absorbent article according to the present invention does not need to include the elastic member 20.

The diaper 10 of the present embodiment has guide portions 12 formed at both ends 10a of the mark 10, and the guide portions 12 cause the folds formed when the diaper 10 is folded to be formed at fixed positions. Therefore, in the pants-type absorbent article according to the present invention, the guiding part is not an essential structure and may be omitted.

In the above description, the pants-type disposable diaper 100 was explained as an example of the pants-type absorbent article according to the present invention, but the pants-type absorbent article according to the present invention can be used as long as it is used by overlapping the auxiliary absorbent pad. The diaper is not limited to diapers that are often disposable when the auxiliary absorbent pad is replaced, but may be one that continues to be reused over a period of time until the auxiliary absorbent pad is replaced multiple times.
