洩れを防ぐことが望ましい。 In the past, various disposable diapers have been proposed for use on infants. Such diapers can usually be classified into two categories: That is, (a) a diaper that is rectangular and can be partially unfolded when applied to an infant, and (b) a diaper that has a special shape other than a rectangle and is designed to fit the infant well. In general, rectangular diapers are difficult to provide a comfortable fit for infants (particularly at the thighs of the diaper), while diapers with unusual shapes are often difficult to manufacture. In many cases, specially shaped diapers require the use of complex and precise machinery to mass produce, resulting in higher selling prices for consumers. Moreover, it is desirable that the specially shaped diaper prevents leakage as it ages, especially in the thighs of the diaper where the most fluid transfers into the diaper.

のが好ましい。 The method of manufacturing the diaper of the present invention has been described with reference to FIGS. 1-6. In this method, the back side of the absorbent pad is covered with a fluid-impermeable backing sheet that is wider than the pad. Next, the side portion of the back sheet is folded back along a folding line that extends vertically between the side edge of the pad and the side edge of the back sheet. Fix the edge of the folded side part to the front surface near the side edge of the pad, and cut a slit in the folded side part of both sides from the fold line to the side edge of the pad between the folded part and the edge of the diaper. A notch is formed on the side of the plate. Therefore, a barrier is formed on the folded side between the side edge of the pad and the slit to prevent leakage from the pad through the slit. The flap panels are made by placing two folded flap panels at the above intervals on the front surface of the pad along the folding line extending vertically at intervals between the pads.
It is preferable to attach it to the front surface of the pad in the middle of the fold line of the book.
