Description

  The present invention relates to a pants-type disposable diaper that absorbs and holds urine and stool for babies and adults.

  It can be divided into a tape type and a pants type according to the type of disposable diapers. The general shape of a tape-type disposable diaper is that the front body of the absorbent body is used to fix the absorbent body to the wearer's body by contacting the vertically long absorbent body so as to cover from the lower abdomen to the crotch and buttocks of the body A side edge is formed on both sides of the part corresponding to the back body, and a pair of fastening tapes are attached to the ends of the side edges of the back body, while the fastening tape is placed on the outside of the absorber on the front body. It is the shape which provided the fixation zone so that can engage. Also, in order not to create a gap around the legs, place elastic elastic bodies such as thread rubber and flat rubber along the absorber on the outside of both side edges of the absorber, and do not create a gap around the belly. In some cases, a stretchable elastic body such as urethane foam, urethane film, or thread rubber is disposed along the edge of the front body side of the absorbent body.

  The tape-type disposable diaper is characterized by adjusting the crotch of the diaper so as not to create a gap around the wearer's leg, and the fastening tape so as not to create a gap around the waist. The engagement position can be freely tightened toward the center of the body. Since such a fastening tape enables crotch fixation, that is, adjustment around the legs, the tape-type diaper has an advantage that it can be adjusted according to the size of the wearer's legs and abdomen.

  On the other hand, a general shape of a pants-type disposable diaper has a front body, a back body, and a crotch part positioned between the two body parts, and joins the opposite side edges of the front body and the back body. Then, a waist opening and a pair of leg openings are formed, and a stretchable elastic body is disposed along each opening.

  The characteristic of the pants-type disposable diaper is that it can be worn in the same way as a so-called cloth pant. Therefore, there are advantages that the diaper can be changed in a short time and that the diaper can be changed while standing.

  The tape type and the pants type are generally used properly, and in the case of diapers for children, the tape type is often used because the baby is often sleeping, and at the time of standing high or high, Pants are preferred because children don't like lying down. In the case of adult diapers, pants-type disposable diapers are preferred if they can take a standing posture at the time of replacement. In addition, there are various levels of physical abilities related to daily life.For example, pants-type disposable diapers for those who can live the same life as healthy people but who suffer from incontinence or who need nursing and walk while using assistive devices Is widely used.

  The disadvantage of pants-type disposable diapers is that there is a tolerance in the dimensions around the legs and around the abdomen, so if the wearer's body shape deviates from the dimensions, a gap will be created between the diaper and the wearer's body, or The tightening may be loosened and leakage may occur from the part. Such a leakage problem has a great influence especially around the legs, and leakage easily occurs when the dimensions of the wearer's legs are smaller than the allowable range of the diaper. For example, depending on the wearer, even if the size around the waist is within the proper range, the size around the leg may be smaller than the allowable range, but in conventional pants-type disposable diapers, the size around the leg is adjusted and worn. I couldn't.

As a method for solving the above-mentioned problems, a method has been proposed in which a fastening tape is attached to a pants-type disposable diaper and the tightness of a loosely worn part is adjusted. For example, either one of the front body and the back body is proposed. A pants-type disposable diaper with a fastening tape attached in parallel to each opening (Patent Document 1) or an intermediate area between the waist opening and the leg opening in the vicinity of the outer periphery of the waist and the opening of the legs A pants-type disposable diaper (Patent Document 2) with a fastening tape attached in the width direction of the diaper in the region around the waist of the diaper, and further, a slit is formed from the leg opening side to the vicinity of the waist part and divided by the slit A pants-type disposable diaper (Patent Document 3) or the like, in which portions are detachably connected by a connecting member (fastening tape), has been proposed.
