20130226126 | ABSORBENT PRODUCT AND DISPOSABLE DIAPER - An absorbent body of a diaper has a central absorbent core, a pair of side absorbent cores and a pair of side elastic members. The side elastic members lie left and right of a front portion of the central absorbent core. The side absorbent cores lie left and right of rear and middle portions of the central absorbent core. In the diaper, by contraction of the side elastic members, the side absorbent cores come into close contact with the insides of thighs of a wearer, and urine is prevented from leaking from leg circumferences. Since the side absorbent cores are positioned left and right of the rear and middle portions of the central absorbent core, portions of the wearer's leg circumferences in the vicinity of the front are not covered with the side absorbent cores, and interference with leg movement of the wearer is prevented. | 08-29-2013 |
20130226127 | ABSORBENT PRODUCT AND METHOD OF MANUFACTURING ABSORBENT PRODUCT - In a disposable diaper in a developed state where a front cover sheet and a rear cover sheet are separated from each other to be developed, as distance in a left-right direction from an absorbent body increases, a lower edge of the rear cover sheet goes away from an upper edge of the rear cover sheet and then goes toward the upper edge. A leg elastic member is bonded on the rear cover sheet along its lower edge, in left and right of the absorbent body. As above, the lower end portion of the rear cover sheet is convex downward in each of left and right of the absorbent body, and lower portions of hips of a wearer are wrapped with the lower end portions. It is therefore possible to suppress leakage of excrement from the lower portions of hips of the wearer. | 08-29-2013 |
