In recent years, in this type of diaper, it has been recognized that it is important to prevent leakage from around the waist (so-called front-rear leakage), and several solutions have been proposed. One of the representative examples is a diaper provided with an elastically contractible waist band all around the waist as described in Japanese Patent Application Laid-Open No. Sho 60-17101. In addition, as disclosed in
As described in Japanese Patent Application Laid-Open No. 83368, there is known a diaper provided with a heat-shrinkable elastic stretching band in place of a normal rubber band around the waist.

However, the conventional diapers have the following disadvantages. That is, in general, in order to attach a disposable diaper to an infant, the infant is turned on the diaper, and the binding tape is joined. Therefore, it is difficult to sufficiently expand the film, and the original elastic expansion and contraction function cannot be exhibited.

In addition, since the elastic member is provided substantially all around the waist, a gather portion having a minute undulation is generated, and the front and rear leaks easily occur from the gather portion. Further, looking back from the viewpoint after completion of the present invention, the elasticity of the elastic elastic member generated in response to the movement of the wearer is concentrated on the side of the waist, and therefore, it is possible to provide the elastic member only on the side. Considering that sufficient fit is ensured, the elastic members other than the side portions are useless.

Therefore, the main object of the present invention is to eliminate waste of material costs,
An object of the present invention is to provide a disposable diaper having improved fit to a wearer.

Means for solving the above problems and achieving the object of the present invention is that the body fluid absorber is wrapped between the water-permeable top sheet and the water-impermeable back sheet and extends outward from the end of the absorber, A disposable diaper having a flap portion at a waist corresponding position and having no absorber, and a bonding tape for joining the front and rear waist corresponding flap portions when the diaper is attached, provided on both sides of the rear waist flap portion. In the corresponding flap part position, when the wearer in the width direction center part of the diaper is turned on his back, it is separated from each other except for the area that is not pressed by the wearer,
An elastic elastic member along the waist direction is fixed on a line connecting the two bonding tapes and in the vicinity of a mounting portion of the bonding tape, and apart from the front waist-corresponding flap portion, apart from the widthwise central portion of the diaper, is separated from each other. Then, elastic elastic members along the waist direction are fixed.

According to the present invention, in the rear waist portion, the elastic elastic member is provided only in the vicinity of the tape attaching portion (the portion corresponding to the side portion of the wearer) connecting the front and rear waist corresponding flap portions, and the diaper width direction central portion is provided. In a case where the wearer is turned on his / her back, they are provided apart from each other except for a region which is not pressed by the wearer. Therefore, there are the following advantages.

When wearing the diaper on the user, after turning the user on the diaper, when connecting the bonding tape, since the elastic elastic member is present only on the side that is not pressed by the user, it is sufficient to stretch the tape Can follow,
An appropriate fit is given to the wearer, and leakage from the back side can be prevented.

In addition, since the elastic elastic member is on the line connecting the two connecting tapes, the elastic elastic member is stretched as it is when the connecting tape is extended, so that the connecting tape can be easily extended. Moreover, after the wearing, the stretching force acting on the disposable diaper accompanying the movement of the wearer mainly acts on the line connecting the two connecting tapes, so that the elastic elastic member is on the line connecting the both connecting tapes, An effect of preventing leakage by satisfactorily following the stretching force on the disposable diaper due to the movement is provided.

In obtaining the required elasticity, the length of the elastic member used can be short, and waste of materials is eliminated. This is the same for the elastic member at the front waist, in which the elastic member extending along the waist direction is fixed at the position of the front waist corresponding flap portion apart from the diaper except for the central portion in the width direction.

As described above, the elasticity of the elastic elastic member generated in response to the movement of the wearer is concentrated on the side of the waist from the body shape and the movement of the body, and therefore, it is sufficient to provide the elastic member only on the side with the elastic member. From the viewpoint that the front waist is fixed to the corresponding flap portions in the front and rear waist portions according to the present invention, the elastic elastic members that are separated from each other along the waist direction except for the center portion in the width direction of the diaper are fixed. In this case, the abdomen can be prevented from being excessively compressed, and the back waist can be prevented from having an elastic expansion / contraction member at the center in the width direction, and in particular, the absence of a gather portion can prevent bedsores.
