Disposable absorbent hygiene article having waistband pockets improving the sealing

A disposable absorbent hygiene article having a general rectangular shape with first and second opposite longitudinal edges and first and second opposite transverse edges and comprising from outside inward:

• a supporting sheet impermeable to liquids having first and second opposite longitudinal edges, first and second opposite transverse edges, an external face and an internal face;
• an absorbent pad having first and second opposite longitudinal edges, first and second opposite transverse edges, an external face, and an internal face, said absorbent pad being arranged on the internal face of said supporting sheet, said pad being smaller in size than said supporting sheet;
• a covering sheet having first and second opposite longitudinal edges, first and second opposite transverse edges, an external face and an internal face, said covering sheet covering the internal face of said absorbent pad and of the supporting sheet and being joined to the supporting sheet around said longitudinal and transverse edges of the absorbent pad;
• longitudinal elastic elements fastened in a tensioned state to said supporting sheet transversely outside the first and second opposite longitudinal edges of said absorbent pad;
• fastening means provided in the vicinity of said first transverse edge of the hygiene article, in order to close the latter around a user's waist in such a way that the hygiene article defines a rear part and a front part corresponding respectively to two end zones near said opposite first and second transverse edges of said hygiene article and a crotch part corresponding to an intermediate zone located between said end zones;
• two transversely spaced lateral flaps arranged on the internal face of the covering sheet substantially along said first and second longitudinal edges of said hygiene article, each of said flaps having a proximal part joined to the covering sheet and a distal part having a tensioned longitudinal elastic element;
• and
• a first additional sheet permeable to liquids having first and second opposite transverse edges, first and second opposite longitudinal edges, an external face and an internal face, said first additional sheet being arranged between the absorbent pad and the covering sheet and extending from said first transverse edge of the hygiene article at least over the first transverse edge of the absorbent pad which is closest to said first transverse edge of the hygiene article;
• wherein said covering sheet further comprises:
• a) a first transverse cutout above the absorbent pad between the proximal parts of said lateral flaps, in the vicinity of said first transverse edge of the absorbent pad, and having a first side confronting said first transverse edge of the hygiene article and a second opposite side;
• and
• b) a first tensioned transverse elastic element extending along said first cutout on said first side thereof confronting said first transverse edge of the hygiene article and having two ends,
• wherein said covering sheet is fastened to the first additional sheet at least along said first transverse edge of the hygiene article and adjacent the two ends of said first transverse elastic element, in order to form a sealing waistband pocket open at the location of said first transverse cutout.
