BACKGROUND OF THE INVENTION
The present invention comprises a bodily fluid-retaining absorbent layer and a bodily fluid impermeable back layer formed on the non-skin contact surface side of the absorbent layer, and when the disposable diaper is worn, the skin contact surface side of the disposable diaper In more detail, the disposable diaper can be repeatedly used without absorbing bodily fluids in the daytime, and can be used at night. The present invention relates to an auxiliary pad for a disposable diaper that can absorb and retain a large amount of body fluid together with the diaper.
[0002]
[Prior art and problems to be solved by the invention]
Generally, as an auxiliary pad for a disposable diaper, a body fluid retaining absorbent layer and a body fluid impermeable back layer formed on the non-skin contact surface side of the absorbent layer are provided, and the disposable diaper is attached when the disposable diaper is worn. There is known an auxiliary pad for disposable diapers that is disposed and used on the skin contact surface side.
This disposable pad for disposable diapers avoids the transfer of bodily fluids to disposable diapers by frequently replacing the auxiliary pad only when the diaper can be changed frequently, such as during the daytime, so that disposable diapers can be used repeatedly and economically. Used for the purpose (for spare). In addition, when the diaper cannot be changed over a long period of time, such as at night, it is used for the purpose of absorbing and holding a large amount of bodily fluid together with the disposable diaper and preventing leakage from the disposable diaper (for absorption assistance).
Moreover, such an auxiliary pad for disposable diapers includes a three-dimensional guard that stands up from the skin contact surface to the wearer.
[0003]
When the conventional auxiliary pad as described above is mounted for a relatively short time, the three-dimensional guard reliably avoids liquid leakage from the auxiliary pad, so that the function as a spare is satisfactorily exhibited. In addition, when wearing for a long time such as at night, the body fluid passes over the three-dimensional guard and is transferred from the side of the auxiliary pad to a disposable diaper and functions as an absorption aid.
However, even in such an auxiliary pad for disposable diapers, when the wearer's operation is intense, such as in the daytime, the auxiliary pad is displaced from the disposable diaper, and body fluid is leaked to the disposable diaper outside the auxiliary pad. May end up.
[0004]
In order to prevent leakage from the outside of the side of the auxiliary pad, it has been proposed that flaps are extended from the left and right side edges of the auxiliary pad. A disposable diaper with a guard has a problem that it is difficult to place stably. In addition, when such an auxiliary pad is stably disposed, it is difficult for body fluid to smoothly transition to a disposable diaper even when worn for a long time, such as at night, and there is a problem that the auxiliary pad is not suitable for absorption assistance.
Conventionally, an auxiliary pad in which the non-skin contact surface side of the absorbent layer is formed of a nonwoven fabric or the like is also known. In such an auxiliary pad, body fluid is well transferred to a disposable diaper and functions well as an absorption aid, but even if a very small amount of body fluid is leaked, the body fluid is transferred to a disposable diaper. Not suitable for use.
[0005]
Accordingly, an object of the present invention is to use the disposable diaper arranged on the skin contact surface side when the disposable diaper is mounted, and in the daytime, the disposable diaper can be used repeatedly without absorbing bodily fluids. Another object of the present invention is to provide an auxiliary pad for a disposable diaper that can absorb and retain a large amount of body fluid together with the disposable diaper at night.
[0006]
[Means for Solving the Problems]
The present invention comprises a bodily fluid-retaining absorbent layer and a bodily fluid impermeable back layer formed on the non-skin contact surface side of the absorbent layer, and when the disposable diaper is worn, the skin contact surface side of the disposable diaper arranged and used as a spare and for absorption aid, an auxiliary pad for disposable diapers, the flap having a body fluid impermeable layer to the left and right both sides of the absorbent layer is extended, the flap, It is bent from the boundary portion between the absorbent layer Yes forms detachably on the back layer, and said back surface layer or the flap, under withdrawal state of the flap, the skin contact surface of the disposable diaper The object is achieved by providing an auxiliary pad for disposable diapers characterized in that it can be adhesively fixed.
