Description

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

  The disposable diapers can be divided into tape type and pants type. The general shape of a tape-type disposable diaper is that the longitudinal absorbent body is in contact with the lower abdomen, crotch, and buttocks of the body so that the absorbent body is fixed to the wearer's body. Side edges are formed on both sides of the part corresponding to the back and back parts, and a pair of fastening tapes are attached to the ends of both side edges of the back part. A fastening zone is provided so that the fastening tape can be engaged. In order not to create a gap around the legs, elastic elastic bodies such as thread rubber and flat rubber are arranged along the absorbent body on the outside of both side edges of the absorbent body. In order not to make it, stretchable elastic bodies such as urethane foam, urethane film, and thread rubber may be arranged along the edge on the front body side of the absorbent body.

  As a characteristic of the tape-type disposable diaper, in order not to create a gap around the wearer's leg, the crotch of the diaper is adjusted, and in order not to create a gap around the waist, Fasten the engagement position toward the center of the body. Since the fastening tape works so that the diaper does not slide down, it also contributes to fixing of the crotch, that is, adjustment around the leg. Thus, a tape type diaper can be adjusted according to a wearer's leg circumference and abdominal circumference.

  On the other hand, a general shape of a pants-type disposable diaper has a front body, a back body, and a crotch portion positioned between the two body parts, and opposite side edges of the front body and the back body. Are joined to form an opening around the waist and a pair of openings around the legs, and a stretchable elastic body is disposed along each opening.

  The pants-type disposable diaper can be worn like the so-called cloth pants, and the abdomen and legs are tightened only by the ablation, and no adjustment is required. Therefore, it is possible to change diapers in a short time and to change while standing.

  The tape type and the pants type are generally used properly. In the case of diapers for children, the infant type is often sleeping, so the tape type is used, and the child lies down when standing high or high. I don't like it, so I prefer pants. 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 are available for people who can live the same life as healthy people but who suffer from incontinence and who need nursing and walk while using auxiliary equipment. 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 is loosened and leakage occurs from the portion. In particular, when the influence around the leg is large and the dimension around the leg is smaller than the allowable range, the leakage tends to occur. For example, depending on the wearer, even if the waist circumference is in the proper range, the leg circumference may be smaller than the allowable range. However, in conventional pants-type disposable diapers, wear around the leg. 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 to adjust the tightening of a loosely worn part. For example, a pants-type disposable diaper in which a fastening tape is attached in parallel to each opening in the vicinity of the waist opening and the leg opening in the outer surface of either the front body or the back body is disclosed (for example, Patent Document 1). Moreover, the underpants type disposable diaper which attached the fastening tape to the waist direction area of the diaper in the intermediate | middle area | region of a waist opening part and a leg opening part in the width direction of the diaper is disclosed (for example, patent document 2). Furthermore, a pants-type disposable diaper is disclosed in which a slit is formed from the leg opening side to the vicinity of the waist, and a portion divided by the slit is detachably connected by a connecting member (fastening tape) (for example, a patent) Reference 3).
