Abstract
Disposable hygiene article is provided including a liquid-permeable topsheet, a liquid-impermeable backsheet, an absorbent core and liquid side barriers arranged substantially along longitudinal edges of the absorbent core and provided to reduce side-edge leakage. The coloured indications are provided on the article along the liquid side barriers to indicate the presence of the liquid side barriers to a user, the coloured indications being provided underneath at least one layer of translucent material so as to be visible through the at least one layer of translucent material while avoiding direct contact with the user's skin.
Claims22
A disposable hygiene article, comprising:
- a liquid-permeable topsheet;
- a liquid-impermeable backsheet;
- an absorbent core arranged between said topsheet and said backsheet, the absorbent core defining a longitudinal centre axis which extends substantially in the middle of the core in a longitudinal direction of the article;
- side flaps disposed on transverse sides of the absorbent core, and
- liquid side barriers arranged substantially along longitudinal edges of said absorbent core and provided to reduce side-edge leakage;
- wherein each of the liquid side barriers is formed by a side layer,
- wherein a longitudinal edge of said side layer overlaps longitudinal edge of said backsheet, the longitudinal edges of the side layer and the backsheet being terminal ends thereof facing a transverse direction,
- wherein coloured indications are provided on the article along said liquid side barriers to indicate the presence of said liquid side barriers to a user,
- wherein coloured indications are positioned between said longitudinal edge of said side layer and said longitudinal edge of said backsheet,
- wherein said coloured indications are provided underneath at least one layer of translucent material so as to be visible through said at least one layer of translucent material while avoiding direct contact with the user's skin,
- wherein, in at least one longitudinal position including the side flaps, the coloured indications do not overlap the absorbent core,
- wherein said at least one layer of translucent material includes the topsheet.

A method for manufacturing a disposable hygiene article,
- wherein the hygiene article comprises:
- a liquid-permeable topsheet,
- a liquid-impermeable backsheet,
- an absorbent core arranged between said topsheet and said backsheet, the absorbent core defining a longitudinal centre axis which extends substantially in the middle of the core in longitudinal direction (L) of the article,
- side flaps disposed on transverse sides of the absorbent core, and
- liquid side barriers including side layers arranged substantially along and overlapping outer longitudinal edges of said absorbent core and provided to reduce side-edge leakage during user of said article,
