Claims
- 1. A disposable diaper which can be secured about a body of a user by means of pressure-sensitive adhesive tape tabs, said diaper having a first end having corners 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 said 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 elongated 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, by glue between said outer surface and said plastic strip,
- said plastic strip having a length and an 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 tension of the diaper around the user by loosening at least one of said tape tabs from said plastic strip, adjusting a relative position of a thus-loosened tape tab and the plastic strip, and refastening the tape tab to said plastic strip in a thus-adjusted position,
- said liquid-tight outer layer being wider at said first end of the diaper than the length of said elongated plastic strip,
- each of said tape tabs having a width no greater than the width of the elongated 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 a side thereof that contacts said plastic strip so that there is adhesion between said tape tabs and 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 said adhesion between said tape tabs and said plastic strip,
- and said plastic strip having a tear strength greater than said adhesion,
- whereby the combination of said liquid-tight outer layer, said plastic strip and said 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.
- 2. A disposable diaper as claimed in claim 1, wherein said single plastic strip is inelastic.
- 3. A disposable diaper which can be secured about a body of a user by means of pressure-sensitive adhesive tape tabs, said diaper having a first end having corners 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 said 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 elongated 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, by glue between said outer surface and said plastic strip,
- said plastic strip having an 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 tension of the diaper around the user by loosening at least one of said tape tabs from said plastic strip, adjusting a relative position of a thus-loosened tape tab and the plastic strip, and refastening the tape tab to said plastic strip in a thus-adjusted position,
- said elongated plastic strip being mounted centrally of said second end of the diaper, and being shorter than a transverse extent of said liquid-tight outer layer at said second end of the diaper,
- each of said tape tabs having a width no greater than the width of the elongated 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 a side thereof that contacts said plastic strip so that there is adhesion between said tape tabs and 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 said adhesion between said tape tabs and said plastic strip,
- and said plastic strip having a tear strength greater than said adhesion,
- whereby the combination of said liquid-tight outer layer, said plastic strip and said 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.
