Abstract
A sanitary absorbent article is provided which has a generally rectangular main body and two positioning tabs laterally extending from the main body for use in securing the article to an undergarment of a user. The tabs, when folded, provide upstanding barriers that extend along the longitudinal edges of the main body to prevent leakage of menstrual fluid.

A sanitary absorbent product comprising a layered elongate main body including a liquid permeable cover layer, an absorbent core and a liquid impermeable barrier layer, said absorbent core being located between said cover layer and said barrier layer, said main body having two opposed longitudinal edges, said longitudinal edges defining a length of the sanitary absorbent product, a positioning tab extending laterally from each of said longitudinal edges of said main body, each positioning tab having a width and a length, the width being substantially parallel to the longitudinal edges of said main body and does not exceed 50% of the length of the main body, each positioning tab including a cover layer portion continuous with said cover layer of said main body and a barrier layer portion continuous with said barrier layer of said main body, each positioning tab having a side barrier device projecting from a body facing surface of each said positioning tab, said barrier device being continuous and integrally formed from the cover layer and barrier layer of the respective positioning tab, and wherein said barrier device has a length which does not substantially exceed the width of said positioning tab.
A sanitary absorbent product comprising:
- a layered elongate main body, comprising from top layer to bottom layer a cover layer which is permeable to liquid, at least one absorbent layer and a barrier layer which is impermeable to liquid, said main body having two opposed longitudinal edges and two opposed lateral edges;
- a positioning tab extending laterally from each longitudinal edge of said main body intermediate said lateral edges, each positioning tab comprising a barrier layer portion continuous with the barrier layer of said main body, and a cover layer portion continuous with the cover layer of said main body;
- an adhesive means provided on the barrier layer portion of each positioning tab for attachment of the tab to a garment facing surface of an undergarment;
- the barrier layer portion of each positioning tab being bonded to the cover layer portion of the tab around the perimeter of the tab;
- and
- an upwardly projecting barrier device formed along each interface between said positioning tabs and said main body, said upwardly projecting barrier device being continuous and integrally formed from the cover layer and barrier layer of the respective positioning tab and having a length not substantially exceeding a width of a respective positioning tab at said interface, each positioning tab having a maximal width not substantially exceeding 50% of a maximal length of said main body.
