Claims28
A diaper, especially for infants, comprising
- an outer sheet of plastic foam which is elastic and air-permeable but water-impermeable,
- an inner sheet of plastic foam which is elastic, air-permeable, and water-permeable,
- a water absorbent pad located between said outer sheet and said inner sheet, and
- fastening means fixed on two opposite side margins of the diaper in order to close the diaper around the waist of the infant.

A diaper, especially for infants, comprising
- an outer sheet of plastic foam which is elastic and air-permeable but water-impermeable and is at least partially reticulated,
- an inner sheet of plastic foam which is elastic and air-permeable and water-permeable and is at least partially reticulated,
- a water absorbent pad located between said outer sheet and said inner sheet, and
- fastening means fixed on two opposite side margins of the diaper in order to close the diaper around the waist of the infant.

A diaper especially for infants, comprising
- an outer sheet,
- an inner sheet,
- a water absorbent pad in between said outer sheet and said inner sheet, and
- fastening means fixed on two opposite side margins of the diaper in order to close the diaper around the waist of the infant,
- the outer sheet and the inner sheet each being made of a first and a second layer of the same elastic plastic foam material, which is at least partially reticulated, said second layer being thicker than said first layer, so that said outer sheet is air-permeable but water-impermeable and said inner sheet is both air-permeable and water-permeable.
