A disposable diaper put on by means of pressure-adhesive tape, has a liquid-permeable inner layer closest to the user during use of the diaper, a liquid-tight outer layer, and an absorbent layer disposed between the inner and outer layers. Tape tabs at one end of the diaper close to the corners of the diaper have a portion permanently joined to the liquid-tight outer layer at that diaper end. A plastic strip for fastening the tape tabs when putting the diaper on the user is disposed on the opposite end of the diaper and consists of a material which is inelastic and has suitable properties for fastening the tape tabs as well as removing and refastening the tape tabs. The plastic strip is elongated transversely of the diaper to permit adjustment of the tension of the diaper around the user by loosening and refastening the tape tabs. The strip extends across the width of the diaper on the outside of the liquid-tight outer layer. The tabs are also fastened to the same side of the liquidtight outer layer.

A disposable diaper which can be secured about the body of a user by means of pressure-sensitive adhesive tape tabs, said diaper having a first end and a second end opposite said first end, comprising: a liquid permeable inner layer closest to the user during use of the diaper; a liquid-tight outer layer having an inner surface and an outer surface; an absorbent layer disposed between the inner layer and the liquid-tight outer layer; a pair of tape tabs at said first end of the diaper, each tape tab being positioned close to a respective one of the corners of said first end of the diaper with a first end portion of each of said tape tabs being permanently joined to the liquid-tight outer layer at said first end of said diaper; and a single plastic strip comprising a material selected from the group consisting of polypropylene and polyester glued on said outer surface of said liquid-tight outer layer, adjacent said second end of said diaper, said plastic strip having an embassed exposed plastic surface away from the user serving as a tape-receiving surface for releasably fastening the pair of tape tabs when putting the diaper on the user, said plastic strip comprising a material which has suitable properties for fastening of the pair of tape tabs thereto as well as easy removal of the tape tabs therefrom and refastening of the tape tabs thereto, without risk that the plastic strip will stretch and be broken by the removal of the tape tabs therefrom, said plastic strip being elongated transversely to the diaper to permit adjustment of the tension of the diaper around the user by loosening at least one of said tape tabs from said plastic strip, adjusting the relative position of the loosened tape tab and the plastic strip, and refastening the tape tab to said plastic strip in the thus adjusted position, each of said tape tabs having a width no greater than the width of the plastic strip, each of said tape tabs having a second end portion opposite from its first end portion, each said second end portion having a pressure sensitive adhesive on the side thereof that contacts said plastic strip, whereby said plastic strip extends as a belt continuously between the tape tabs when the diaper is secured about the body of the user, said adhesive having a greater cohesion than the adhesion between said tape tabs and said plastic strip, and the tear strength of said plastic strip being greater than the adhesive strength of said tape tab adhesive for the material of said plastic strip, whereby the combination of said liquid-tight outer layer, said plastic strip and the glue therebetween allows said tape tabs with said adhesive thereon to be releasable from and refastenable to said plastic strip without stretching and breaking said plastic strip.
