[Embodiment of the invention]

 Hereinafter, the present invention will be specifically described based on embodiments. The structure for preventing leakage of the absorber of the present invention is applied to sanitary articles used for absorbing excrement from the human body. As shown in FIGS. 1 and 2, in the first embodiment, a disposable diaper 2 is used. Has been applied.

More specifically, the disposable diaper 2 includes a surface layer 20 that is hydrophilic and permeable to liquid, a bottom layer 21 that is water-impermeable and impervious to liquid, It has an absorption layer 22 interposed therebetween. The surface layer 20 completely penetrates the liquid, the absorbing layer 22 sandwiched between the surface layer 20 and the bottom layer 21 absorbs the liquid, and the bottom layer 21 prevents the liquid absorbed in the absorbing layer 22 from penetrating. It is to prevent. The periphery of the surface layer 20 and the periphery of the bottom layer 21 are integrally bonded to each other. As this bonding method, for example, a known method such as heat sealing or ultrasonic sealing is used.

The disposable diaper 2 has a buttocks 23, a crotch portion 24, and a lower abdomen 25 extending from a predetermined position along the periphery and covering corresponding portions of the body. The buttocks 23, the crotch portion 24, and the lower abdomen 25 are provided with side wings 230, 240, 250 on both sides facing each other in the longitudinal direction. Here, the side wings 230 of the buttocks 23 and the side wings 250 of the lower abdomen 25 are formed substantially symmetrically with a large protrusion amount. The side wing 240 of the crotch portion 240 has a slight amount of protrusion, is located between the side wings 230 and 250, and continuously connects them.

The side wings 240 of the crotch portion 24 are formed with partitioning folds 241 made of a material through which liquid cannot penetrate, and the partitioning folds 241 are provided with elastic members 242 therein. In this embodiment, a band-shaped elastic material is applied as the elastic member 242.

On both side wings 250 of the lower abdomen 25, first blocking edges 251 which are inclined in opposite directions (directions approaching each other) are formed at bases thereof, where the side wings 250 start to protrude. The first blocking edge 251 is fixed by a heat seal or an ultrasonic seal with an adhesive resin. In addition, the buttocks 23 and the lower abdomen 25 are provided with elastic members 231 and 252 made of the same elastic band as described above at both longitudinal edges of the disposable diaper 2.

When the wearer wears the disposable diaper 2 having the above configuration, the first blocking edge 251 on the front surface rises to form a blocking wall. In addition, the arrangement of the elastic members 231, 242, and 252 attached to the buttocks 23, the crotch portion 24, and the lower abdomen 25 makes it possible to optimally adjust the size according to the size of the waist of the wearer and provide an extremely comfortable wearing feeling. Can be.

Then, of the excrement excreted from the body of the wearer, the liquid permeates from the surface layer 20 into the interior and is absorbed by the absorbent layer 22 below the excrement. In addition, the liquid is prevented from leaking to the outside by a partition wall 241 formed on both sides of the crotch portion 24 and a blocking wall formed by the first blocking edge 251 on the front surface. Therefore, even if the wearer stands or sits, there is no possibility that the liquid in the excrement leaks out from both sides of the crotch portion 24 and both sides of the lower abdomen 25. As a result, it is possible to prevent the wearer's kimono from being stained.

FIG. 3 shows a disposable diaper 2 as an absorber according to a second embodiment of the present invention. The disposable diaper 2 is different from the first embodiment in that second diametrical edges 232 which are inclined in opposite directions (directions approaching each other) are provided at the bases of the buttocks 23 where the side wings 230 start to protrude. Is different. The second blocking edge 232 is fixed by heat sealing or ultrasonic sealing with an adhesive resin as in the first embodiment.

When the wearer wears the disposable diaper 2 of the second embodiment, similarly to the first embodiment, the first blocking edge 251 on the front surface rises to form a blocking wall portion, and the second blocking portion 251 is formed. Separator 232 rises to form a blocking wall. The first and second blocking edges 251 and 232 and the partition fold 241 of the crotch portion 24 form a substantially box-shaped accommodation chamber.

Therefore, it is possible to reliably prevent the liquid in the excrement excreted from the wearer from leaking from around the disposable diaper 2 and contaminating the underwear. That is, even if the wearer stands, sits, or sleeps, the liquid in the excrement is formed by the partition pleats 241, the first blocking edge 251, and the second blocking edge 232 provided on the periphery of the disposable diaper 2 of the present invention. Does not leak from the buttocks 23, crotch 24 and lower abdomen 25, and does not stain the kimono or sheets.

FIG. 4 shows an absorbent body according to a third embodiment of the present invention. In the third embodiment, the leakage prevention structure according to the first and second embodiments is applied to a female sanitary napkin 3. It is.

The sanitary napkin 3 has a surface layer through which liquid can penetrate, a bottom layer through which liquid cannot penetrate, and an absorbent layer interposed between the surface layer and the bottom layer, similar to the disposable diaper 2. Has a length extending from the buttocks to the lower abdomen through the crotch. On the surface of the surface layer, partitioning folds 30, a first blocking edge 31 and a second blocking edge 32 are arranged at edges facing both sides along the longitudinal direction.
