2. Description of the Related Art In a pants-type disposable diaper disclosed in Japanese Utility Model Laid-Open No. 5-39531, a strip of adhesive tape extending in the girth direction is provided on each of the left and right sides, and the total number of soiled diapers is two. It can be rolled using tape. By doing so, even if dirt is attached to the diaper, it can be discarded in a hygienic condition.

[0003]

SUMMARY OF THE INVENTION
In the diaper of Japanese Patent No. 31 gazette, if the left and right side portions are rolled so that they are inward, the adhesive tape may be hidden and may not be used. If feces are excreted while wearing a pants-type diaper, the diaper may be removed by cutting open the left and right sides of the diaper. It is preferable that the cut-out diaper be rounded so that each side is inward so that the soiled area cannot be peeked outside by stool. At that time, it is necessary to avoid the situation where the adhesive tape cannot be used.

Further, since this diaper does not have a means for widely closing the diaper rolled in the width direction in the vertical direction, in a large adult diaper or the like, the soiled portion tends to be seen outside.

Therefore, the present invention has an object to make it possible to close the disposable diaper widely when it is rolled in the width direction.

[0006]

In order to solve the above-mentioned problems, in the present invention, a liquid-absorbent core is interposed between a liquid-permeable top sheet and a liquid-impermeable back sheet, and a front waist region is formed. And an adhesive tape that can be used to roll the diaper on the outer surface of the back sheet of either of the front and rear waist regions of a disposable diaper having a rear waist region and a crotch region located between these two regions. It is intended for disposable diapers.

On this premise, the feature of the present invention resides in that the adhesive tape is composed of at least two adhesive tapes extending in parallel to each other in the waist circumference direction of the diaper and spaced apart in the vertical direction. is there.

In a preferred embodiment of the present invention, one end of each of the double-sided adhesive tape is fixed to the outer surface of the back sheet at the center in the width direction of either of the front and rear waist regions, and the remaining portions of these tapes are It extends around the waist of the diaper in the same direction or in opposite directions.

[0009]

The details of the disposable diaper according to the present invention will be described below with reference to the accompanying drawings.

A pants-type disposable diaper 1 shown in a partially cutaway perspective view in FIG. 1 is viewed from the back side, and has a liquid permeable top sheet 2, a liquid impermeable back sheet 3 and
It is composed of the liquid-absorbent core 4 interposed between these sheets 2 and 3, and has a front waist region 6, a back waist region 7, and a crotch region 8 located between these both regions 6 and 7. . The front and rear waist regions 6, 7 are joined to each other by overlapping the left and right side edges to form left and right waist sides 11, 12, and a waist opening 13 and a pair of left and right leg openings 14 are formed.
And are defined. A plurality of elastic members 16 and 17 are joined to the inner surfaces of the front and back sheets 2 and 3 in a stretched state at the peripheral edge of the waist opening 13 and the peripheral edge of the leg opening 14, respectively. On the outer surface of the back sheet 3 at the center in the width direction of the rear waist region 7, there are double-sided adhesive tapes 19 and 20 for use when rolling the soiled diaper 1.
One ends 19A and 20A of the tapes 19 and 20 are fixed to the outer surface of the back sheet, and the remaining portions 19B and 20B are folded so that they can be extended in the left and right directions in the figure, as indicated by imaginary lines.

2 and 3 show the adhesive tape 1 in FIG.
It is the II-II line and III-III line arrow line view of 9 and 20. One ends 19A and 20A of the tapes 19 and 20 are fixed by a hot-melt adhesive 24, and the remaining freely deformable portions 19B and 20B are attached to required parts on both sides by the adhesive material 2.
6 has an adhesive area 27 formed by applying 6,
The folded state is maintained by the action of the adhesive 26. The tapes 19 and 20 are surface-treated so that the surface facing the pressure-sensitive adhesive 26 can be easily peeled off when folded, and the tapes 19 and 20 are stretched by grasping and pulling the respective end portions 19C and 20C.

FIG. 4 is a perspective view of the diaper 1 rolled up for disposal, in which (A) is the rear waist region 7 and (B) is the front waist region 6. . Diaper 1
After the crotch region 8 is folded over the front waist region 6, the left and right waist regions 11, 12 are rounded with the front waist region 6 inside. As is apparent from (B) of the figure, the adhesive tapes 19 and 20 are wound around the waist and the tape 19
The adhesive area 27 of the tape 20 is fixed to the outer surface of the rounded right waist side portion 12, and the adhesive area 27 of the tape 20 is fixed to the outer surface of the rounded left waist side portion 11. These tapes 19,2
When 0s are vertically separated from each other as shown in the figure when being fastened, the rolled diaper 1 is in a state of being widely closed in the vertical direction, so that the soiled portion of the diaper is less likely to be exposed. By the way, when the diaper 1 is to be closed wide like this, if the adhesive tape is a single strip,
The tape is much longer than that shown in the figure, and its handling becomes complicated.

The necessity of rolling the soiled diaper 1 as shown in FIG. 4 is as follows. Feces may be excreted while an infant is wearing a pants-type diaper 1, and if the diaper 1 is pulled down and taken off, the feces may stick to various parts of the body. In order to avoid this, the worn diaper 1 may be cut open at the left and right waist circumference side parts 11, 12 to separate the front and rear waist circumference regions 6, 7 and the diaper 1 may be detached from the body. This will reduce the amount of rubbing your body with a dirty diaper. However, in the diaper 1 cut open in this way, a dirty part may be seen from the cut side part or filth may leak out, so that the open side parts 11 and 12 are respectively separated as shown in the drawing. Diaper 1 so that it is inside
It is preferable to round and discard. This is the need.

Further, even when the diaper 1 is not of pants type but of open type, it can be rolled up as shown in FIG. If there are adhesive tape fasteners on the left and right edges of the diaper, it is possible to roll the diaper with it. However, such a fastener is similar to the diaper disclosed in Japanese Utility Model Laid-Open No. 5-39531.
In addition to the possibility of hiding when the diaper is rolled up,
Since the length of the adhesive tape 1 may not always be sufficient, the adhesive tape 1 shown in FIG.
It is preferable to have 9, 20.

FIG. 5 is a drawing similar to FIG. 2, showing an example of an embodiment of the diaper 1. In this diaper 1, two strips of adhesive tape 19 and 20 are attached so as to extend in the same direction around the waist.

FIG. 6 is a drawing similar to FIG. 2 showing another example of the embodiment. This diaper 1 adhesive tape 19,2
No. 0 has a perforation 30 extending in the longitudinal direction at the center in the width direction of each freely deformable portion 19B, 20B. If such portions 19B and 20B are cut and used at the perforations 30 when fastening them, it becomes easy to further widen the fastening area in the vertical direction of the diaper when fastening as shown in FIG. . This aspect may be applied to a large size diaper for adults.

In the present invention, the adhesive tapes 19 and 20
A plastic film or a non-woven fabric can be used for the tape substrate. The tapes 19 and 20 are used to form the adhesive regions 27 on the required sites on both surfaces thereof, to fold the tapes 19 and 20 and to roll the diaper 1. However, the free ends 19C and 20C for gripping are
It is preferable that both surfaces are non-adhesive. Tape 19,
20 may be in any of the front and rear waist regions 6, 7.
In the diaper 1 shown in FIGS. 2 and 4, in addition to being rolled from both the left and right sides as in the illustrated example, it is also rolled from one side to form two adhesive tapes 19,
It is also possible to use only one of 0.

[0018]

In the disposable diaper according to the present invention,
The two strips of adhesive tape, which have one end fixed to the widthwise central part and extend in the girth direction, are separated from each other in the vertical direction of the diaper, so that they do not hide when the diaper is rolled in the width direction, The vertical fastening area of the diaper can be widened so that even large diapers do not look into the dirty area.
