Description

  The present invention has a pair of left and right fastening tapes on the left and right side edges on one end (first end) in the longitudinal direction, and the fastening tape is provided on the other end (second end) in the longitudinal direction. The present invention relates to a so-called unfolded disposable diaper that is attached to the body by being fastened to a landing tape.

As an unfolded disposable diaper, for example, Patent Document 1 discloses a disposable diaper that facilitates fastening of a fastening tape by bending at least both ends of a landing tape toward the rear side of the diaper.
However, the disposable diaper described in Patent Document 1 does not correspond to various physical characteristics and body shapes of the diaper wearer, and is particularly sufficient for a wearer having a body shape smaller than the adaptation size of the diaper. Can't give fit.

  Further, conventionally, a mark such as a vertical line indicating the fastening portion of the fastening tape is printed on the landing tape, and the fastening tape is fixed to the landing tape by matching the tip of the fastening tape to the mark. It is known that the diaper is roughly fitted to the individual body shape of the diaper wearer. For example, Patent Document 2 discloses a disposable diaper that displays on a landing tape a linear index that serves as a mark of a fastening portion of a fastening tape and a numerical index that includes the average waistline and underbody dimensions of the wearer of the diaper. Has been.

  However, in order to fasten the fastening tape according to such a numerical index, it is necessary to measure the body shape of the diaper wearer in advance, in order to wear the diaper utilizing the numerical index Requires complicated work. In addition, since various body type values measured in advance are not always accurate, if fastening of the fastening tape is performed only depending on the numerical index, not only a sufficient fit can be obtained, but also the diaper wearer's There is a risk of preventing the fastening of the flexible fastening tape that matches the body shape. In addition, for example, the body shape of the infant's abdomen protruding forward has three-dimensional characteristics that cannot be expressed sufficiently only by the numerical indices as described above, and the body shape of the diaper wearer changes greatly when hungry or full. For this reason, even if accurate body measurements are taken, it is difficult to say that wearing diapers according to numerical indices is always appropriate for fitting diapers. The surface of the landing tape is a particularly conspicuous part of the diaper, and the design in which straight lines and numerical values are written on the surface is mechanical and not interesting. In particular, in diapers for infants, the design of the surface of the landing tape may be an important element for selection when purchasing diapers, and the diaper described in Patent Document 2 has room for improvement in terms of design. .

Regarding the design of a landing tape on which an index indicating the fastening location of a fastening tape is displayed, Patent Documents 3 and 4 disclose disposable diapers in which a design correlated with the design of the outer surface of the landing tape is applied to the outer surface of the fastening tape. It is disclosed. According to the disposable diapers described in Patent Documents 3 and 4, the design applied to the outer surface of the landing tape is not obstructed by the fastening tape, and there is no sense of incongruity, and the fastening tape is fastened to the landing tape. It is thought that fun will be produced. Moreover, according to the patent document 3, according to the disposable diaper described in the patent document 3, it is said that it can be educated with respect to the infant who is a wearer.
However, the disposable diapers described in Patent Documents 3 and 4 cannot be said to correspond to various physical characteristics and body shapes of the diaper wearer, and the fastening tape is stopped according to the index displayed on the outer surface of the landing tape. Even when worn, there was a case where a sufficient fit could not be obtained.
