Abstract

Abstract The invention refers to an anatomic absorbent which contrary to similar products exhibits dynamic and anatomic action, ac­companying the movement of the body of the user and providing increased protection against leakage. The absorbent of the invention comprises an absorbent substrate (3) sandwiched between a permeable and an impermeable layer (1, 2) which are sealed to each other at least at the ends of the absorbent. On each side, at least along a part of its length, there is provided between the edges of said layers (1, 2) a strip (6) of heat-shrinking material in the contracted state, so that each side takes the form of a raised flap (4 and 5). Said layers are bonded to the strips (6) at a plurality of regions interspaced along the lengths of the strips, there being no continuous bond between the layers and those parts of the flaps which are provided with the strips.

Claims Analysis

Total Claims: 7
Claim 1
Independent Claim 151 words
Elongated anatomic absorbent comprising an absorbent substrate sandwiched between a fluid impermeable layer designed to be remote from the body of the user, and a fluid permeable layer for surface contact in the perineal area of the user, said layers being bonded to each other at least at the ends of the absorbent, and the sides of the absorbent having elastic means which provide it with an anatomic curved profile, characterized in that each said elastic means comprises a strip (6) of heat-shrinkable material in the contracted state, so that the sides of the absorbent take the form of flaps (4, 5) raised with rela­tion to the horizontal, said layers (1, 2) being bonded to the strips at a plurality of regions interspaced along the lengths of the strips, the bond between the layers not being continuous in those parts of side flaps (4, 5) which are provided with the strips.
Claim 2
Dependent Claim 151 words
Elongated anatomic absorbent comprising an absorbent substrate sandwiched between a fluid impermeable layer designed to be remote from the body of the user, and a fluid permeable layer for surface contact in the perineal area of the user, said layers being bonded to each other at least at the ends of the absorbent, and the sides of the absorbent having elastic means which provide it with an anatomic curved profile, characterized in that each said elastic means comprises a strip (6) of heat-shrinkable material in the contracted state, so that the sides of the absorbent take the form of flaps (4, 5) raised with rela­tion to the horizontal, said layers (1, 2) being bonded to the strips at a plurality of regions interspaced along the lengths of the strips, the bond between the layers not being continuous in those parts of side flaps (4, 5) which are provided with the strips.
Claim 3
Dependent Claim 26 words
Anatomic absorbent according to claim 1, characterized in that the length of each strip covers from 40 to 80% of the respective side of the absorbent.
Claim 4
Dependent Claim 25 words
Anatomic absorbent according to claim 2, characterized in that the length of each strip (6) is approximately 60% of the respective side of the absorbent.
Claim 5
Dependent Claim 28 words
Anatomic absorbent according to claim 1, 2 or 3, character­ized in that each of said layers (1, 2) is made from pieces of material having straight parallel sides.
Claim 6
Dependent Claim 60 words
Anatomic absorbent according to claim 1, 2 or 3, character­ized in that said absorbent substrate (3) comprises a first layer (9) in contact with said permeable layer, having re­silient characteristics; a second central layer (10) serving as a fluid reservoir; and a third layer (11) in contact with the impermeable layer, said three layers of the substrate being successively shorter.
Claim 7
Dependent Claim 21 words
Anatomic absorbent according to claim 5, characterized in that said second layer (10) of the absorbent substrate includes super absorbent material.
