Claims15
An absorbent article, comprising:
- an absorbent pad having a front surface, a film of thermoplastic material covering at least a portion of the front surface of the pad in a fluid receiving region of the article, a fluid pervious top sheet covering said film in said region, said top sheet having an outer surface facing away from the film, said film having a plurality of fluid transmitting openings extending through the film in said region, and said top sheet being fused against the film in a pattern defining a recessed configuration in the outer surface of the top sheet.
An absorbent article, comprising:
- an absorbent pad having a back surface, and a thermoplastic backing sheet covering at least a portion of the back surface of the pad, said backing sheet having an outer surface facing away from the pad and a pattern fused into the sheet against said pad defining a recessed configuration in the outer surface of the backing sheet.
A disposable diaper, comprising:
- an absorbent pad having a front surface, and a perforated film of thermoplastic material covering at least a portion of the front surface of the pad in a fluid receiving region of the diaper, said film having an outer surface facing away from the pad, a closely spaced pattern fused into the film against the pad defining a recessed configuration in the outer surface of the film, and a plurality of fluid transmitting openings in said region, said openings comprising perforations enlarged by heating in the locality of said pattern from a size of 0.2 to 7 mms to a size of 0.2 to 8 mms.
A disposable diaper, comprising:
- an absorbent pad having a front surface, a fluid pervious top sheet covering at least a portion of the front surface of the pad, and a film of thermoplastic material intermediate said top sheet and pad, said film having a pattern fused against the top sheet and pad defining a recessed configuration of the front surface of the diaper, and a plurality of fluid transmitting openings extending through the film in the locality of said pattern, said openings being enlarged from perforations of a smaller size in said film.
An absorbent article comprising, an absorbent pad having a front surface, and sheet means, including a perforated film of thermoplastic material, covering at least a portion of the front surface of the pad and having a closely spaced pattern fused into the film to define a recessed configuration of the front surface of the article, said pattern defining a mesh-like configuration in said film, with the fineness of the configuration being in the range of 4 to 1000 mesh, and said film having a plurality of openings comprising a portion of said perforations enlarged from a smaller size by heating in the locality of said pattern.
A method of making an absorbent article, comprising the steps of:
- placing a film of thermoplastic material against a back surface of an absorbent pad;
- and
- fusing a pattern into said film against the back surface of the pad to define a partially recessed outer surface of the film relative the pad.
A method of making an absorbent article, comprising the steps of:
- perforating a film of thermoplastic material;
- placing the perforated film and a sheet of fluid pervious material against a surface of an absorbent pad with the film located intermediate the sheet and pad;
- and
- heating the sheet and film in a pattern to enlarge a plurality of film perforations and fuse the film to the sheet and pad in the locality of the pattern.
A method of making an absorbent article, comprising the steps of:
- placing a film of thermoplastic material against a front surface of an absorbent pad;
- placing a sheet of fluid pervious material against an outer surface of the film;
- and
- fusing a pattern into the film against the sheet and pad to define a partially recessed front surface of the article.
