1. a pants type disposable diaper, its predecessor and after engage in sidepiece, form waist opening portion and pair of right and left leg opening part, the feature of described pants type disposable diaper is:

  • Described pants type disposable diaper has;

    the outermost thin slice forming the profile of described pants type disposable diaper;

    With the tabletting that the mode covering the part except waist on the inner face of described outermost thin slice is fixing;

    Absorber, is fixed on the inner face of described tabletting, extends in the longitudinal direction centered by hip crotch pars intermedia;

    And front and back leakproof thin slice, extend to described waist from the leading section of described absorber and rearward end respectively,Described outermost thin slice turns back at the most inner face of described pants type disposable diaper in waist opening portion, and this fold back portion is fixed on above the waist of described front and back leakproof thin slice,The junction surface of the sidepiece of described predecessor and described rear body is formed as, the multiple square unit of longitudinal arrangement fuses portion at certain intervals, and it is continuous that the unit of sustained height size fuses portion, form unit and fuse portion'"'"'s group, in addition, units different for each height dimension is fused portion'"'"'s component and become interval, described longitudinal direction refers to the bonding position of abdominal part side and side, backDescribed junction surface, from described waist opening portion side to described leg opening part side, is divided into following four intervals;

    Between waist area, be made up of the fold back portion of described outermost thin slice, described outermost thin slice, described front and back leakproof thin slice, laminated sheet number is total three layers;

    Rib upper interval, be made up of the fold back portion of described outermost thin slice, described outermost thin slice, described front and back leakproof thin slice, described tabletting, laminated sheet number is total four layers;

    Rib pars intermedia is interval, and be made up of outermost thin slice, described front and back leakproof thin slice, described tabletting, laminated sheet number is total three layers;

    Between rib lower region, be made up of described outermost thin slice, described tabletting, laminated sheet number is two-layer for adding up to,The pass that unit in these intervals described fuses the height dimension in portion is described in described rib upper interval >

    between waist area >

    =the interval >

    of described rib pars intermedia described between rib lower region,The height dimension that described unit fuses portion is, is 0.3-3mm between described waist area, is 0.5-5mm in described rib upper interval, and be 0.3-3mm in described rib pars intermedia interval, be 0.1-2mm between described rib lower region.
