Description

[0001]
TECHNICAL FIELD OF THE INVENTION
The present invention relates to a disposable diaper, and more particularly, the present invention relates to a tape-type disposable diaper having excellent wearability and fit, and particularly having an excellent effect of preventing leakage from around the legs. .
[0002]
[Prior art]
Generally, the caregiver's work load when changing diapers is very large, and the care recipient is physically and mentally burdened. Furthermore, if excrement leaks out of the diaper due to the excretion of the wearer, it is necessary not only to change the diaper, but also to change clothes, sheets, etc. Is also a huge burden. In addition, since the physical and mental burdens on the cared person become even greater, improvement of leakage is strongly desired.
[0003]
In addition, in the case of a disposable diaper, one of the leak-prone parts is around the legs. Especially in the case of tape-type disposable diapers, since the wearer can be from temporary wearing due to injury or long-term bedridden due to paralysis, illness, etc. There is a large individual difference, and depending on the wearer, there is a case where a gap is easily generated around the leg and a leak is easily generated.
[0004]
Generally, a tape-type disposable diaper is provided with a fastening tape having an adhesive or a fastening means such as a mechanical fastening system on both side edges of the body, and the diaper is attached by the fastening tape when the diaper is attached. It is configured so that the back body and the front body can be concluded. Usually, one or more fastening tapes are attached to the left and right sides of the disposable diaper. The former is often used for newborn babies and infants, and the latter is used for adults. It is often found in diapers.
[0005]
In a conventional tape-type disposable diaper, when a plurality of fastening tapes are attached to both side edges of the rear body, they are all attached at right angles to the longitudinal direction of the diaper. Therefore, when the diaper is worn, the fastening tape attached to the waist circumference is fastened so that the seam of the back body and the front body that is substantially perpendicular to the longitudinal direction of the diaper fits the user's body. However, if the fastening tape attached to the leg circumference side is pulled in the placement direction and fastened as it is, the fit around the wearer's leg is insufficient, and the fastening tape between the diaper and the wearer's body Clearance was likely to occur.
[0006]
Especially for wearers who have been sleeping for a long period of time, fastening tape is fastened in order to fit diapers to such wearers in many cases because they are thin and their hips and legs are thin and their hips are overhanging To do so, it is necessary to pull the fastening tape particularly on the side of the leg circumference at an angle different from the mounting direction, that is, slightly upward. However, when the fastening tape is arranged at right angles to the vertical direction of the diaper, it is difficult to pull up and fasten well, and as a result, a gap is easily generated between the wearer and the diaper, and the leakage is likely to occur. .
[0007]
As described above, the difficulty in securely attaching the diaper to the wearer also leads to the diaper easily loosening or slipping off the wearer's body during use. This loosening and sliding down is considered to be caused by the movement of the wearer, such as walking or changing the posture, and the downward force generated when receiving a load of excrement. If not fitted, loosening and slipping will occur easily and significantly, which will contribute to early leakage.
[0008]
Various proposals have been made to solve these problems. For example, a disposable diaper or the like in which two fastening tapes are arranged on both side edges of the back body and both of them are arranged downward (see Patent Document 1) ), There has been proposed a disposable diaper in which a fastening tape positioned on the side of the opening around the leg is attached obliquely at an angle of up to 45 degrees in the upper direction with respect to the horizontal direction of the diaper (see Patent Document 2). .
[0009]
In addition, two fastening means are attached to the side edges of the left and right side flaps on the back body, and a slit is formed in the side flap between the fastening means in a diagonal direction in a diaper lateral direction or a crotch direction, so as to fit the wearer. Or a disposable diaper in which wings are attached to both side edges of the rear body of the diaper and the wings are bisected to form engaging means. (See Patent Document 5).
