Problems solved by technology

However, in this diaper, since the other side edges of the flaps are joined to each other in the crotch area, they should stand up from the liquid-permeable sheet and contact around the legs of the diaper wearer when the diaper is worn. The flap will fall to the liquid-permeable foreskin, creating a gap with the skin around the legs, which may cause excrement to easily leak from around the legs
In addition, as a result, there may also be a problem of excrement coming into contact with the skin around the legs
