Abstract

According to the invention it is disclosed an absorbent pad (1) comprising a liquid-impervious back sheet (2), a plurality of bodies (3) of liquid-absorbent material disposed on one surface of the back sheet (2), and a liquid-pervious cover sheet (4) covering said bodies (3) of absorbent material and secured to the back sheet (2) along channels (7) which separate said bodies (3) of absorbent material. The channels (7) progresses in a channel-pattern in which three channels (7), meeting in a joint, form respective edges (6) of said whole bodies (3) and said channels (7) being substantially free from absorbent material. A method for the manufacturing of such absorbent pad (1) is also disclosed.

Claims

1. An absorbent pad comprising a liquid-impervious back sheet, a plurality of bodies of liquid-absorbent material disposed on one surface of the back sheet, and a liquid-pervious cover sheet covering said bodies of absorbent material and secured to the back sheet along channels which separate said bodies of absorbent material, wherein;

the channels progresses in a channel-pattern in which three channels, meeting in a joint, form respective edges of said whole bodies and said channels being substantially free from absorbent material.

2. An absorbent pad as claimed in claim 1, in which said edges of said whole body has an angle of 105-135°

, preferably 118-122°

, in relation to nearlying edges thereof.

3. An absorbent pad as claimed in claim 1, in which said cover sheet is adhesively bonded to said back sheet propagating along said channels.

4. An absorbent pad as claimed in claim 1, in which said cover sheet is cohesively secured to said back sheet along said channels.

5. An absorbent pad as claimed in claim 1, in which said back sheet is substantially flat and said cover sheet has pockets therein and containing said bodies.

6. An absorbent pad as claimed in claims 1, in which said bodies contains 6 edges.

7. An absorbent pad as claimed in claim 1, in which said three channels propagates evenly distributed, in the plane of said absorbent pad, from said joint.

8. A method of making an absorbent pad from a liquid-impervious back sheet and a liquid-pervious cover sheet and absorbent material between said sheets, comprising forming in the cover sheet a plurality of bodies, filling the bodies with a separate quantity of absorbent material in each body, and securing the back sheet to the cover sheet along channels between the bodies, wherein;

the channels progresses in a channel-pattern in which three channels meet in joints forming respective edges of said whole bodies and said channels being substantially free from absorbent material.
