特開昭59−144601号公報において知られている。(Prior Art) Conventionally, in a disposable diaper having a waist band, band-shaped elastic elements that stretch in the direction around the waist are intermittently bonded between front and back sheets forming the waist band. A channel is formed between the elastic element and the front and back sheets to provide air permeability.
This is known from Japanese Patent Application Laid-Open No. 144601/1983.

う重大な欠点がある。(Problems to be Solved by the Invention) The channel of the known technique communicates with the inside of the diaper and opens at the outer end of the waistband, so that the crushed pulp constituting the absorbent body of the diaper can be extracted from the channel. Particularly when superabsorbent polymer particles are used as part of the absorbent body, a significant drawback is that a large amount of the particles fall off when the diaper is worn.

is interposed and fixed. Between the front and back sheets 1 and 2 extending outward from both ends of the absorbent body 3 in the width direction, there are elastic leg bands 4 that stretch in the longitudinal direction of the diaper, and also extend outward from the longitudinal ends of the absorbent body 3. Elastic waistbands 5 are interposed and fixed between the front and back sheets 1 and 2, respectively, and a fastening tape 6 is provided at the widthwise end of the rear waistband to connect these and the front waistband.

いるものを採択することができる。 Further, regarding the elastic waist band 5, as shown in FIGS. Moreover, they are arranged in several rows at intervals in the width direction, and the intervals in the longitudinal direction become larger toward the outer ends in the width direction, and the continuous bonded parts 8 are arranged in a continuous linear shape in the longitudinal direction. are adhered to the front and back sheets 1 and 2, respectively. This adhesive means adopts a heat-weldable and heat-shrinkable synthetic resin film as the elastic waist band 5, and heats it to weld (including ultrasonic welding).
It is preferable to do so. In order to impart elasticity to the elastic waist band 5, the elastic waist band 5 may be interposed and fixed between the front and back sheets 1 and 2, and then treated with hot air to shrink it.
The contracted elastic waist band 5 provides gears around the rear waist as shown in the figure. By the way, before the elastic waist band 5 is treated with hot air, the front and back sheets 1 and 2 are
It is preferable for the fixing work to temporarily bond the absorber 3 between the front and back sheets 1 and 2, but in order to fix the absorber 3 between the front and back sheets 1 and 2, a hot-melt type adhesive coated on the inner surfaces of the front and back sheets 1 and 2 in several rows is preferable. It is best to use adhesive. The length of the elastic waist band 5 may be the same width as the front and back sheets 1 and 2, or it may be shorter than the width of the front and back sheets 1 and 2 so that it can be drawn in from both widthwise ends of the front and back sheets 1 and 2. Although not particularly limited, the extension length (width) of the front and back sheets 1 and 2 forming the rear waist area without the absorbent body 3 intervening from 5 mm, taking into consideration stretch elasticity, design, and economic efficiency. It is determined, but preferably 10 to 40 mm. Heat-fusible and heat-shrinkable synthetic resin films are already known, for example, as disclosed in U.S. Patent No.
Those described in the specifications of No. 3819401 and No. 3912565 can be adopted.

公知おむつのように脱落することが全くない。(Operations and Effects of the Invention) According to the present invention, since the elastic waist band 5 is fixed around the waist, elastic gears are formed around the waist, and the waist is elastically brought into close contact with that of the wearer. The general function of the elastic waist band 5 is that it can prevent the leakage of excrement from the waistband.
Not only is it effective, but it also has the following functions and effects. That is, first, the elastic waist band 5 and the front and back sheets 1 and 2
and are sealed with a continuous adhesive part 8, so that
Even if pulverized pulp is used as the absorbent material 3 and superabsorbent polymer particles are used in order to improve its absorption and retention properties, these particles will not fall off from around the waist like the previously mentioned known diapers. do not have.

In other words, each non-bonded part, which is located between each adhesive part and can freely expand and contract, becomes wider as it goes towards the outer end in the width direction. Because I'm getting used to it,
The diaper improves adhesion to the wearer's waist and adjusts the compressive force, so even if the diaper is worn for a relatively long time, it does not give an unpleasant feeling of pressure to the waist.
